Free -style skiing originated

Freedom skiing was born in the United States in the 19th generation. At that time, the United States was in a period of change. The psychology of people's eagerness of freedom prompted this new stimulating Ski project to appear in front of people.This project initially only set the alpine skiing and acrobatics. After decades of development, it became what it is today.

The first free Ski competition was held in the 19th Hampshire. In the following ten years, many brave people created a lot of thrilling movements, and this sport has gradually taken shape.

The International Ski Federation formally recognized free skiing projects in 1979, and formulated new rules in terms of athletes and their jumping skills to reduce the danger of this sport.The first World Cup Freedom Ski Series was held in 1980. France held the first World Free Ski Championship in 198.Freedom skiing is divided into three small items, including snow skills, air skills and ballet on snow.

one,SkiletWhat is

Skiboard is a skiing equipment, which invented Nordic in the early 20th century to increase the speed of skiing during skiing.The structure of the Ski panel consists of a base, arched head, contact, edge, effective edges and bending points.Skiboards are mainly divided into two types: skiing veneer and Ski double board. With the continuous progress of technology, skiing boards have been differentiated into many different types.

2. There are several types of skiing boards

1. All Mountain Skis

This is the most common type. Most of the snow friends use this type. The all-round board can actually be classified as this column, with the waist width of 68-75.This type of board is generally reduced by 15 cm to 5cm.If you choose, look at the level and skiing habits.Beginners recommend that they choose short, good control, and good technology improvement.Senior skiers actually prefer to enjoy the fun brought by speed, so that the board must be relatively long.In addition, people with heavy weight should choose a little longer.

Just like its name, the goal of this Skiboard aim is to glide in any region.Its shape is very close to the Carving skiing, so it is still suitable for taxi on the compact snow surface.It is different from the Carving skilets in its waist width. Most of them are between 75 and 90 mm, which can give you more buoyancy in the snowy snow.There are many global skiing boards, all kinds of shapes and hardness, some like traditional traditions with Ski panels, while others look more like free -style skiing boards.

2. Carving Skis (Carving Skis)

Carving skiing board is the most used Skiboard for most casual Ski people.It is very suitable to glide on the compact snow trail and there will be a lot of fun.Generally speaking, the waist of the snowboard (the position under the foot of the Ski) is about 70 to 80 mm width, and the width of the head and tails exceeds 110 mm.This shape allows the Skiboard to slip along the edge of its edge.

3. Free -style Ski board

Free -style skiboards are very similar to wild snowboards, but they are not so wide.Its design goals are mainly targeted at gliding outside the snow road, but it can also slip well in the snow channel.It is slightly wider than skiing plates across the region, and its waist is generally between 80 and 100 mm.The mainstream free -scale Ski board will have some Rocker, and the board head and the tail of the plate are slightly raised from the side.This design helps skiing to float on various snow surfaces, and can easily change the direction of gliding. At the same time, it can also provide sufficient grip on the compact snow surface.

4. Wild Snow board (Powder Skis)

Wild snowboards are generally between 88-120.(Some people say that the waist width of the wild snowboards generally from 90 mm to 140 mm, and the length is generally 170 cm to 200 cm.) As mentioned above, wild snow buoyancy is the key.Choosing a wild snowboard is generally as tall as height, and such as those with a width of 110 or more, it is difficult for you to find boards below 176cm.You sink in the 5 -meter -deep wild snow, but it is difficult to get up.

Compared to the snow trail, the wild snowboard has a wider and longer body, but the snowboard elasticity is softer.The larger length and width can provide sufficient buoyancy in the deep and soft snow.Some wild snowboards have designs called Rocker or head and tails. Compared with ordinary snowboards, the wild snowboards start to rise up in the head and tail., To provide more control capabilities.There are also some wild snowboards that have the waistline that are opposite to ordinary snowboards, that is, the width of the head and the tail of the plate is narrower than the waist waist. This design is still to improve the buoyancy and handling in the powder snow.

5. Big Mountain Skis

The waist width of the high mountains and wild snowboards is usually between 90 and 130 mm. It is harder and longer than ordinary skilets.Takayama Wild Snowboards are usually 180 to 210 cm long. This snowboard is the favorite of extreme Ski people.

6. SLALOM Skis (SL Skis)

This kind of skiing plate is generally divided into large turns and small rotation.The level of skiers who can control the competitive board should be very high.Large turning boards are generally choosing a length of similar to their height, and small backboards generally choose the length of 15cm.But if you pursue speed, choose a little longer, so that the stability is higher.

Compared to the above -mentioned snowboards, the small competitive schola plates look very short. The length of the snowboard used by the fastest competitors in the world today is about 160 cm (but these people will not consider any shorter than 205 cm in previous years.To.The small turn board is dexterous and reactive. It can turn on the solid snow surface at an incredible speed, but this kind of board is not a good choice for the unsuccessful snow trail and deep snow.

7. Giant Skis (GS Skis)

The large back Ski board has a longer waist radius than the small backplane, and it is harder, so its turn radius is longer.It is also used to glide at high speed on a solid snowway, usually more length than the small turn board to enhance stability and grip.

8. Fancy skiing board (two-ends of skiing boards, TWIN-TIP Skis)

The two -ends are the favorite of those who like to challenge the semi -Tube snow trails and venue parks, and are also called Freestyle Skis.This kind of Ski board is very soft, and the tail is raised, and it can provide better tolerance when jumping up.Please try it before choosing a fancy board.At the same length, fancy boards can slide like the entire area plate. If the performance allows, a slightly shorter fancy board is also possible.

9. Cross Country Skis

The main difference between off -road board and all Alpine Skis mentioned above is that it is not only designed to slide from the landscape, it is very light and easy to wear in a vast area.Its fixed device allows the skiers to lift the heels of the Ski, walking as usual.Compared to other snowboards, in order to provide grip in the process of moving forward, its bottom bottom has texture.The usual skiing boards need to be waxed and choose different types of wax according to different snow quality, while it does not need to be waxed and easy to use.

10. Competitive off -road Ski board (Cross Country Racing Skis)

Competitive off -road boards are used to move quickly on compact Ski trails. It is very narrow and is not suitable for snowfills that are not opened on the road.There are two types of competitive off -road boards, one is a straight slip, and the other is the traditional pedal ice type.Because it is necessary to judge which type of snowboard is more suitable for yourself according to the Ski style, its own weight, and the local snow quality, only you can choose the Ski board through the above factors.

11. Touring Skis (Touring Skis)

This is a Ski board used by the Alpine Touring activity. This Ski board has a variety of width and style.The wider model, especially the type of metal edge, can travel through or engaged in Ski Camping activities in rugged terrain.The narrow and lighter model is generally used to travel on a gentle terrain or compact snow.Many people now use free Ski panels to replace the climbing board, which can adapt to more snow quality.Backcountry skiers usually need a pair of stop skating bands to the bottom of the snowboard to help climb.

three,SkiletWhat is the length

When choosing the length of the skiing board, the maximum is limited to the height of the wrist that does not exceed my arm, and the shortest should not be shorter than the crotch.Choose a long relief snowboard to use fast, good stability, short Ski board speed, slow fibrillation, poor stability.

For beginners, too long skiing boards are not easy to control, and it is difficult to turn it. It is not conducive to improving their technical level. Beginners are best to add about 5 cm with their height.Beginners should also choose skiing boards with large elasticity.Because this kind of Skiboard is not easy to bump when it encounters uneven snow surface, the braking effect is better, and it is easier to operate.

Emerging agricultural machinery equipment, replacing traditional manual operations, has the characteristics of high efficiency and convenient carriers to get the love of farmers' brothers!

definition

The seeder refers to the planting machine with crops and seeds as the object. The seeder has the characteristics of uniform seeding, consistent depth, stable lines, good soil covering, saving seeds, and high work efficiency.

Pay attention to the main points

Pay attention to the following points to master the following points:

Before entering the field, clean up the debris in the seed box and the entanglement and soil on the ditch to ensure a good condition. The transmission and rotation parts of the tractor and the seeder will be injected with lubricating oil according to the requirements of the instructions, especially in particular, especiallyBefore each job, pay attention to the lubrication and tension of the transmission chain, and the tightening of the bolt on the seeder;

The rack cannot be tilted. After the seeding machine is connected to the tractor, it must not be tilted. When working, the front and back of the rack should be in a horizontal state;

To do a good job of various adjustments, in accordance with the provisions and agronomy requirements of the instruction manual, the seeding amount, the spacing of the ditch, and the depth adjustment of the ditch to the soil suppression wheels are appropriate;

Pay attention to adding the seeds and add the seeds of the seed box to achieve no small, , and miscellaneous to ensure the effectiveness of the seeds; secondly, the amount of seed boxes should be added to the entrance to the breeding box to ensure the Smooth seeds smoothing the Smooth breeding boxesItems

In order to ensure the sowing quality of the seeder, before the large -scale sowing, you must insist on the trial broadcast for 20 meters to observe the work of the seeder.Ask agricultural technicians, local farmers and other test consultations to confirm the local agronomy requirements, and then plant large -scale seeding;

Pay attention to the uniform speed line, and the agricultural machine handles choose the operation to walk the route. It should be convenient for the addition and mechanical entry and exit. When sowing, pay attention to the straight line forward.

In order to prevent the ditch from blocking, the lifting of the seeding machine should be operated during the travel, and the seeding machine should be lifted when retreating or turning;

Predse the ground first, first sow the ground to avoid rolling the ground, causing deep broadcasts; regular observation, often observing the work conditions of the gaunting device, ditch, coverage, and transmission mechanism during sowing., Covering grass and seeds are not strictly covered, and timely eliminate it.

Adjusting, repairing, lubricating or cleaning up grass, etc., must be carried out after parking;

When the protection of the machine, when the seeding machine is working, it is strictly forbidden to retreat or turn sharply.

Pay attention to the seed box, the seeds in the seed box during operation must not be less than 1/5 of the seed box volume;

When transporting or transferring the block, there must be no seeds in the seed box, let alone other heavy objects.

history

The first seeder was made in Greece in 1636.In 1830, the Russians installed the seedlings on the livestock plow to make a plow broadcasting machine.After 1860, Britain, the United States and other countries began to produce large amounts of animal grain sowers after 1860.After the 20th century, traction and suspension grain seeders appeared one after another, as well as the seedlings using forceful seedlings.In 1958, the first centrifugal seeder appeared in Norway, and various precision seeders gradually developed after the 1950s.

The seeder was introduced in the 20th century, and in the 1960s, it was successfully developed a variety of models such as the suspension grain seeding device, centrifugal seeder, universal rack seeder, and air -suction seeder.Formulator.By the 1970s, two series of sowing plowing machines and grain joint seeding device had been formed and put into production.Various broadcasting machines and acupoints for grains, farming crops, pastures, and vegetables have been promoted and used.At the same time, a variety of precision seeders were successfully developed.

maintenance method

After the seeding season is over, the dust on the seeds is completely cleaned, and the seeds and Fertilizers in the seed box are cleaned.The friction parts and transmission devices of the seeding machine are cleaned, and lubricate, such as the transmission chain, and apply the rust -proof agent after drying.Check the tightness of the connector. If there is a loose, it should be tightened in time.

The exterior and seeding shaft of the gear transmission device of the seeder should be coated to lubricate oil.The springs should be adjusted to a free state of freedom.The sowing machine should be placed in a dry and ventilated warehouse. If it is kept in open -air, the wooden seed box must be covered, and the seeding machine should be matched in two wheels.The frame should also be padded to prevent deformation.The preparation, parts and tools should be stored in the library. After the seeding machine is stored for a long time, it should be maintained early before sowing in the next season.

The metal transmission Tube of the seeder should be removed. Do not deform in the indoor control. Relax the telescopic springs of the ditch.place.The disc truncapus must be decomposed. After cleaning the diesel, reassemble and get the oil. The surface of the inside and outside of the disc is coated with waste oil. It is placed in a dry and covered room.Get up with a wooden board.

If the seedlings or ditch of the seeder, if it is blocked, clay, grass, and seed coverage, it should be excluded in time.Adjusting, repairing, lubricating, or cleaning the seedworm entanglement, etc., must be carried out after parking; when the seeder work, it is strictly forbidden to retreat or turn sharply.The seeds inside should not be less than 1/5 of the seed box volume; when transporting or transferring the blocks, there must be no seeds in the seed box, let alone other heavy objects.The precautions for the use of the seeder are not limited to the above points. Farmers need to be continuously accumulated by reading product manuals and farming practice.

Life

Sowing device is a very common agricultural machinery equipment used in rural areas. As long as it is a equipment, it cannot avoid loss during the use process. So how can we minimize this loss? This requires us to use it in daily use.Do a series of maintenance work before and after.In this way, it can ensure that the equipment can be used normally and allows the service life of the equipment.

Before use: If it is a product of the previous year, you need to check the transmission parts of the gear of the seeder, check whether the parts can operate normally, can be applied to lubricating oil for maintenance, and the spring device corresponding to each component needs to be checked.If there is a loose and more slippery, the user uses the newly purchased products without these operations. It only needs to be assembled;

When used: installation and use according to the technical requirements of the manufacturer, the Fertilizer box should not be loaded. Do not operate vigorously when sowing. It is forbidden to pull down or turn sharply.

After use: thoroughly clean up the Fertilizer box and place the seeder in a ventilated and dry warehouse. If the open -air is kept, the seeder should be covered with operations. To prevent parts from damage, disassembly and keeping can be performed.

A device that allows user income, you can rely on the quality of the equipment itself, and add reasonable operation methods and maintenance methods, so as to ensure the product's maximum effect and increase the service life of the product.
