Description

A spring-tooth sprocket type residual film recovery machine

technical field

The invention belongs to the field of agricultural machinery, and in particular relates to an elastic-tooth sprocket type residual film recovery machine suitable for crops with relatively regular film covering and small stubble.

Background technique

In recent years, plastic film mulching cultivation technology has been popularized and applied to the cultivation of vegetable fields, which has solved the problem of low temperature and water shortage in dry land in cold and cold regions, thus starting a large-scale promotion and application. After using plastic film mulching planting technology, due to the increase of effective temperature, the growth period is relatively extended, and middle and late maturing varieties can be widely used, so that the quality and yield can be greatly improved. At the same time, the suitable growing areas of various crops are shifted and expanded to the north, so that the land resources can be used more effectively. The moisture conservation effect produced by plastic film mulching promotes the deep rooting of crops, so it is also a drought-resistant measure, which has important strategic significance for the effective use of water resources and the development of early-land agriculture in my country.

Although plastic film mulching planting technology is an effective way to increase crop yield, if the residual film left in the field cannot be recycled in time, it will not only cause environmental pollution, but also cause serious harm to agricultural production itself. Residual film recycling is one of the important factors affecting the sustainable development of agricultural production, which has been recognized by more and more people. At present, the Chinese government and some agricultural production departments have begun to invest manpower, material and financial resources to solve the problem of residual film recycling. But overall, due to the large planting area covered by plastic film in my country, the long period of film laying, and the untimely recycling and treatment of residual film, the number of waste and residual film in rural areas has increased sharply, and "white pollution" has appeared in many places.

There is an MS-2 film harvesting machine at the seedling stage developed by Northeast Agricultural University. The principle is to loosen the pressed film soil on both sides of the ridge with a soil loosening shovel, and the two film rolling wheels roll along the front edge of the ridge, and the plastic film is rolled by the film picking teeth. The film cutting knife cuts the film, and the film is wound on the film rolling wheels on both sides by the rolling of the film rolling wheel. On the one hand, the machine completely rolls the film on the film roll. When unloading the film, it must be cut off from the middle with a knife to unload the film. It is cumbersome and difficult to unload the film; on the other hand, the film winding wheel is a driving wheel. Plastic elongation of the film is not compensated resulting in unreliable winding.

The IMC-70 type residual film picking and stubble machine developed by the Agricultural Mechanization Research Institute of Inner Mongolia Autonomous Region uses a tractor to travel during operation. In the separation sieve, the residual film, root stubble and soil clods rotate in the roller sieve, and under the action of centrifugal force, the soil clods are crushed and thrown to the ground through the screen holes. The residual film and root stubble left in the roller sieve are thrown into the film-collecting basket, and when it is full, the film stubble is unloaded into piles by human operation. The machine entangles the residual film with the stubble, which cannot be separated and can only be separated by burning, resulting in a low recovery rate of the residual film. In addition, the two shovels scoop up the root stubble and residual film, which is equivalent to sieving the ground surface once, and consumes a lot of power.

Detailed ways

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings, and the present invention is not limited to the following examples.

As shown in Fig. 1 and Fig. 2, they are respectively the front view and the top view of the elastic sprocket type residual film recovery machine of the present invention.

The spring tooth sprocket type residual film recovery machine comprises a frame 19 and a film collecting box 8 installed on the frame 19, the traction frame 1 is connected to the front end of the frame 19, and the ground wheels 6 are symmetrically arranged on the left and right sides of the frame 19. side. The ground wheel 6 is coaxially installed with the first driving sprocket 7. The first driven sprocket 11 is installed on the film collecting box 8, and the second cam 12 and the third cam 14 are symmetrically distributed on both sides of the first driven sprocket 11 and are installed on the film collecting box 8. The sprocket 7 is connected with the first driven sprocket 11, the second cam 12 and the third cam 14 through a chain drive; the second cam 12 and the third cam 14 rotate in the same direction as the first driving sprocket 7, and the first driven sprocket The sprocket 11 rotates counterclockwise with the first drive sprocket 7 . The second driving sprocket 13 is installed on the bearing seat of the frame 19, coaxially installed with the first driven sprocket 11. The second driving sprocket 13 is connected with the second driven sprocket 2 through the crawler belt 5 , and the second driven sprocket 2 is installed on the second driven sprocket shaft 15 . The track 5 is tensioned by the first cam 4 . Multiple rows of crawler rods 18 are arranged on the crawler belt 5, and a plurality of spring teeth 10 are arranged on the crawler rods 18; 10 spring teeth. The film stripping plate 9 is fixed on the film collecting box 8, the film stripping plate 9 has a plurality of slits, and the elastic teeth 10 pass through the slits of the film stripping plate 9.

The surface of the crawler belt 5 is covered with a lightweight leak-proof film 16, such as canvas, to prevent the mulch from being wrapped around the crawler belt 5, and the elastic teeth 10 pass through the lightweight leak-proof membrane 16.

Lug connection on tensioner shaft 17. When the extension spring 3 shrinks, the lug on the tensioner shaft 17 is close to the lug on the frame 19, so that the tensioner shaft 17 rotates counterclockwise, because the first cam 4 is rigidly connected with the tensioner shaft 17 , and then the first cam 4 moves counterclockwise, so that the vertical distance between the first cam 4 and the side beam of the frame 19 increases, and then the first cam 4 pushes the crawler belt 5 downward, which increases the stroke of the crawler belt 5 as a whole, so that the crawler belt 5 tensioned.

When the elastic tooth sprocket type residual film recovery machine of the present invention is working:

The traction frame 1 is connected with a tractor, and the tractor provides power. The traction frame 1 drives the ground wheel 6 to roll forward, and the ground wheel 6 drives the first driving sprocket 7 to rotate, thereby driving the first driven sprocket 11 to rotate in the reverse direction. A driven sprocket 11 drives the second driving sprocket 13 to rotate, thereby drives the second driven sprocket 2 to rotate, and then drives the crawler belt 5 to rotate, and the rotation of the crawler belt 5 drives the elastic teeth 10 on it to rotate, thereby driving the whole residual Circular movement of the film recovery machine; when the elastic teeth 10 turn to the ground position, they contact the plastic film, so that the plastic film can be picked up, and the elastic teeth 10 rotate with the caterpillar 5 to the position of the stripping plate 9 with the raised plastic film. 10 passes through the slit of the stripping plate 9, and the stripping plate 9 takes off the mulch film picked up by the elastic teeth 10, and the film taken off is collected by the film collecting box 8. When the extension spring 3 is tightened, the shaft of the first cam 4 is driven to rotate counterclockwise, so the first cam 4 can tighten the entire crawler belt 5 to enhance the adaptability to the terrain.
