Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural technology, in particular to a seeding and mulching device for wheat planting and a method thereof. BACKGROUND

[0002] In the process of wheat seeding and planting, mulching is needed, which can effectively improve soil temperature, promote the germination of wheat seeds and the growth of seedlings, especially in low temperature environment. Meanwhile, mulching can also reduce soil water evaporation and maintain soil humidity, providing a stable water environment for wheat growth. In addition, mulching can also inhibit weed growth to some extent and reduce the occurrence of diseases and insect pests, which is conducive to the healthy growth of wheat and the improvement of final yield. These advantages make seeding and mulching an important cultivation and management measure in wheat planting.

[0003] In the traditional film pressing process, the soil is turned to the edge of the film by the soil turning wheel, and the film edge is pressed. Since the soil mound is in the form of a bulge, the film edge is downward. In order to ensure the high utilization rate of land area during mechanical planting, the pressing area of the film is controlled as small as possible. If the pressing area of the film is too large, the planting area of the wheat machine will be reduced accordingly. At the same time, if the soil block is too small, there will be a pressing force, and if the soil block is too large, it will roll down from the pressing position because of the bulge form of the soil mound. With the passage of time, the film edge will be exposed. Once the film edge is exposed, it will be lifted by the exposed position in the case of strong wind. In this case, some equipment uses a point-by-point soil covering form on the film. Although this can solve the problem of film edge exposure to a certain extent, it is very difficult to handle when the film is lifted. The film will be damaged due to the increase in weight of single-point soil covering and the aging of the film after long-term use. Therefore, the present application proposes a seeding and mulching device for wheat planting and a method thereof to solve the problems in the prior art. SUMMARY

[0049] Embodiment two

[0050] According to Figure 1 、 2 , 3, 4, 5, 6, 7, 8, the embodiment proposes a seeding and film mulching method for wheat planting, comprising the following steps:

[0051] The device is connected to the power car to the land, and is pulled by the power car to move in cooperation with the first crawler wheel 2 and the second crawler wheel 3.

[0052] After adjusting the seeding distance, the front-end punching assembly and the seeding assembly are punched and seeded at equal intervals in sequence;

[0053] According to the width of the film mulching required, the spacing between the two groups of wheel frames 5 is adjusted, and then the driving part is adjusted to drive the linkage shaft 12 to rotate, and the linkage shaft 12 drives the wheel shaft 8 to rotate through the gear part, so that the two ends of the press wheel 9 are tilted to the required angle at the same time;

[0054] The first air cylinder 6 pushes the press wheel 9 downward, and after punching and seeding, the press wheels 9 on both sides of the front end roll out the film groove on both sides of the top of the seeded soil;

[0055] The film mulching roller assembly releases the film, which is wound around the first guide roller 21 and the second guide roller 22 to the seeded soil, and the press wheels 9 on both sides of the rear end press the film into the film groove at the same time;

[0056] As the device moves, the soil shoveling assembly at the rear end shovels the soil to both sides of the top of the film mulching to the film groove for fixing the film mulching; a double film mulching groove is formed on both sides of the film to form a double film mulching form, which effectively avoids the exposure of the film edges;

[0057] After a certain distance of film mulching, the film released by the film mulching roller assembly is cut off by the cutter 60, and when the film is released, the film mulching roller assembly is replaced with a new film.

[0058] The sowing film covering device for wheat planting adopts a compound film pressing form, and a film pressing groove is added on both sides of the film to form a compound form. Specifically, the spacing between the two sets of wheel frames 5 is adjusted according to the required width of the film, and the operating drive part drives the linkage shaft 12 to rotate. The linkage shaft 12 drives the wheel shaft 8 to rotate through the gear part, so that the pressure wheels 9 at both ends are synchronously tilted to the required angle. After punching and sowing, the first cylinder 6 pushes the pressure wheel 9 downward, and the pressure wheels 9 on both sides of the front end will roll out film pressing grooves on both sides of the top of the sowing soil. After filming, the pressure wheels 9 on both sides of the rear end press the film into the film pressing groove, and the soil-moving component moves the soil to both sides of the top of the film to fix the film in the film pressing groove, which can effectively avoid the exposure of the film edge and will not be lifted up in strong winds. When peeling off the film, the soil on the film pressing groove can be lifted to both sides, which will not affect the integrity and work efficiency of the film peeling. The present invention releases the film through the film roller 27 on the arc groove. When the film on the film roller 27 is used up, the second cylinder 30 lifts the bending arm 29, so that the first arc claw 31 and the second arc claw 32 move upward, and the first arc claw 31 pushes the new film roller at the front end of the second hook plate 25 from the second hook plate 25 to the inside of the first hook plate 24. The second arc claw 32 pushes the film roller on the arc groove 33 through the one-way door 34 to the top of the first hook plate 24, and rolls it into the storage groove 35 for storage depending on the inclination of the first hook plate 24, thereby completing a roller replacement process, which is more convenient to use. At the same time, when punching holes, the eccentric wheel 48 rotates, driving the swing arm 52 to swing, pulling the pulling arm 54 to swing, thereby pulling the punching column 56 up and down to punch holes in the soil. By adjusting the position of the adjusting block 53, the depth of the punching is changed, and the number and interval of the punching holes are adjusted by removing the belt 50 of the eccentric wheel 48 at different positions. When sowing, the rotating disk 43 rotates to drive the eccentric movement of the connecting arm 44, pulling the pulling plate 45 and the slide plate 40 to reciprocate, thereby switching the slide plate 40 to block the discharge pipe 41 and connect the discharge pipe 41 with the sowing pipe 42 for interval discharging. According to needs, the sowing pipes 42 at different positions can also be blocked to change the number and interval of sowing, and the functions are diversified.
