A kind of ground film precision sealing machine

Abstract

The invention discloses a mulch film precision soil sealing machine, which comprises a transmission system, a soil taking and filtering system, a soil delivery and soil sealing system and a ground soil distribution profiling system. The transmission system transmits power to each sprocket in sequence through a gearbox and a shaft, wherein the soil is finely crushed by a soil taking wheel assembly and a soil crushing sprocket, and is transported to the middle of the drum through a soil delivery roller, and the pushing has the function of further crushing soil blocks. Afterwards, the crushed soil is further evenly pushed to the soil delivery unit through a left spiral drum and a right spiral drum. Due to the action of the soil retaining bucket of the soil delivery roller, a certain amount of crushed soil is guaranteed to fall into the soil discharge port. In the ground soil distribution profiling mechanism, the ground profiling of the soil guide trough ensures that the discharge height of the soil guide trough is always at a certain height with the ground, thereby ensuring that the crushed soil is evenly spread at the hole sowing port of the plant seedling, and the hole sowing port on the film is sealed, and the mulch film is connected by simulating wind disasters, so as to achieve the purpose of soil sealing.

Description

Technical Field

[0001] The invention relates to a crop film hole sowing and soil sealing machine, in particular to a film cotton precision soil sealing machine, belonging to the technical field of agricultural machinery. Background Art

[0002] Film covering planting has been widely used in various places, especially in the arid areas of northern my country. The planting of cotton adopts the precision hole-seeding technology of punching holes on the film. Especially after the cotton seedlings emerge, the openings on the hole-seeding film need to be covered with soil to prevent the film from being blown up by strong winds in bad weather. If this work is done manually, it will take a lot of time and effort, and the cost is high. In order to adapt to the development of modern agriculture, the use of mechanical soil covering has become an important agronomic demand for cotton planting in our region. However, the existing machines have uneven thickness of the soil covering layer, and the problem of soil falling and damaging the seedlings is relatively common.

[0003] In view of the above problems, the present invention creates a precision soil sealing machine for mulch film. After taking soil through the soil-taking wheel, it adopts mechanical power to crush and screen, and evenly distributes it to the soil sealing outlet through a spiral feeder. Then, through the ground profiling wheel, the finely crushed soil is evenly spread to the opening of the hole-sowing mulch film, and the height of the fallen soil is guaranteed to be consistent, the soil sealing is uniform, and seedling damage is prevented. Summary of the invention

DETAILED DESCRIPTION

[0013] The invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] As attached Figure 1As shown, the tractor is connected to the rear of the tractor through a three-point suspension on the frame 1, and transmits power to the gearbox through the rear power output shaft. The gearbox 15 then transmits power to the shaft 14. The soil taking and soil crushing parts are arranged symmetrically on the left and right. After the soil taking wheel cover 13 is cut open, it can be seen that the left soil taking wheel assembly 3 has a certain scimitar, and the shaft 14 distributes power to the driving sprockets 4 at both ends. The left and right soil taking wheel assemblies 3 connected to the shaft 14 rotate to cut the soil on the surface and throw it to the upper and rear left and right soil crushing spike teeth 2, and send it to the top of the soil crushing spike teeth 2. The soil crushing spike teeth 2 rotate to further crush the soil on the surface.

[0015] As mentioned above, the left driving sprocket 4 distributes power to the left soil crushing sprocket 5 and the soil feeding sprocket 5 through chain transmission and drives them to rotate together, and distributes power to the left soil crushing spike teeth 2 and the soil feeding sprocket 6 respectively. The right driving sprocket 4 distributes power to the right soil crushing sprocket 5 and the soil covering sprocket 17 through chain transmission, and drives them to rotate together, and distributes power to the right soil crushing spike teeth 2 and the soil covering sprocket 17 respectively.

[0016] As mentioned above, the left and right soil crushing sprockets 5 drive the left and right soil crushing spike teeth 2 to rotate, and the crushed soil thrown by the left and right soil wheel assemblies 3 is further crushed. The crushed soil passes through the sieve of the left and right soil crushing grid bars 7 and falls into the soil feeding roller 12 below. At this time, the soil feeding roller 12 rotates through the power transmitted by the soil feeding sprocket 6, and the finely crushed soil is transported to the middle of the roller. At this time, the pushing of the soil feeding roller 12 also has the effect of further crushing the soil blocks.

[0017] As mentioned above, after the soil delivery roller 12 delivers the crushed soil to the middle, it is pushed to both sides by the left spiral roller 8 and the right spiral roller 10 respectively. Due to the retaining effect of the soil retaining bucket 11, a certain amount of crushed soil can be ensured to fall into the lower discharge port of the soil retaining bucket, ensuring the uniformity of the discharge.

[0018] As mentioned above, the soil guide trough bracket 19 below the stage outlet sends the crushed soil into the soil guide trough 9. Since the roller 18 installed on the soil guide trough 9 is in contact with the ground and is hinged to the soil guide trough bracket 19 through the rotating pin 20, the ground profiling of the soil guide trough 9 is realized, thereby ensuring that the unearthed height of the soil guide trough 9 is always at a certain height with the ground, ensuring that the crushed soil is evenly spread on the hole sowing opening of the mulch film of the plant seedlings, and the hole sowing opening is sealed to achieve the purpose of sealing the soil. After the soil feeding roller 12 sends the crushed soil to the middle part, the wind is pushed to both sides by the left spiral roller 8 and the right spiral roller 10. Due to the soil retaining effect of the soil retaining bucket 11, it can be ensured that a certain amount of crushed soil falls below the soil retaining bucket at this time, ensuring the uniformity of unearthing.

[0019] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions created by the present invention and are not intended to limit the present invention. Although the innovations of the present invention have been described in detail with reference to the preferred implementation modes, those skilled in the art should understand that the technical solutions created by the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the solutions of the present invention, which are all included in the scope of the claims of the present invention.
