Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology for cotton planting, specifically a film edge covering soil device to prevent drifting. Background Technology

[0002] The core agricultural tool used for soil covering in cotton planting is the cotton sowing and soil covering device (often integrated with the seeder, called "cotton sowing and soil covering integrated machine"). Its core advantages are high efficiency and precision, which can ensure a stable environment for cotton seed germination. It can complete soil covering immediately after sowing, reduce the number of times agricultural machinery enters the field, reduce damage to the soil structure (especially avoid soil compaction), and shorten the operation cycle, seizing the sowing window period.

[0003] An investigation revealed a utility model patent for a thickened biodegradable double-film seeding device (publication number: CN222776591U), comprising a frame body. The frame body has traveling rollers positioned at its lower left and lower right. Between these traveling rollers, from left to right, are arranged a lower film roll, a seeding turntable, a soil-covering turntable, and an upper film roll. Vertical supports are adjacent to the right sides of the lower and upper film rolls. An auxiliary pressure roller is rotatably connected to the bottom of each vertical support. This utility model, through the inclusion of a suction fan, suction pipe, suction connector, suction hood, limiting support, and vertical support, facilitates the use of both biodegradable and thickened film layers in the double-film seeding operation. During this operation, the device utilizes a side-end suction structure to smooth the edges of the film layers, preventing uneven or inconsistent film coverage during subsequent covering operations.

[0004] Although the aforementioned patent improves the soil covering effect during the sowing process and reduces the wrinkling of the film edges by setting up components such as exhaust fans, soil covering turntables, and auxiliary pressure rollers, thereby improving cotton growth conditions, the different particle sizes of soil clods in the soil during the sowing and soil covering process will lead to different pressing effects of the film covering. Often, the film edges will drift due to different weights of covering, which is very detrimental to providing the quality of film covering.

[0005] Therefore, this utility model provides a membrane edge covering device to prevent drift, in order to solve the above problems. Utility Model Content

[0018] (III) Beneficial Effects

[0019] By setting up the soil covering component, the mulching effect during cotton sowing can be improved through the cooperation of various components. During the operation of the equipment box, the soil cutting blade feeds soil clods into the equipment box, and then the screening component screens large soil particles. The loose soil is sent to the discharge pipe by the suction machine, and then the soil covering is quickly inverted to the edge of the film through the discharge pipe. The weight of the soil covering presses down on the film and prevents it from drifting. At the same time, the airflow in the discharge pipe blows the film above the film through multiple blow pipes, further improving its flatness. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a membrane edge covering device to prevent drifting, such as... Figures 1-5 As shown, the anti-drift membrane edge covering device includes a mounting frame 1 and a covering component, the covering component including an equipment box 2 welded to the outer surface of the mounting frame 1;

[0029] A rotating base 3 is fixedly connected to the inner wall of the equipment box 2. A rotating roller 4 is rotatably sleeved on the inner wall of the rotating base 3. A cutting blade 5 is fixedly sleeved on the outer wall of the rotating roller 4. A protective box 6 is installed on the outer wall of the equipment box 2. A suction machine 7 is installed inside the protective box 6. A feed pipe 8 is fixedly connected to the input end of the suction machine 7. A suction disc 9 is fixedly connected to the end of the feed pipe 8. A discharge pipe 10 is fixedly connected to the output end of the suction machine 7. A discharge trough is opened on the outer wall of the discharge pipe 10. A screening component is set inside the equipment box 2.

[0030] The soil covering assembly also includes a purge pipe 11 fixedly sleeved on the outer wall of the discharge pipe 10. There are several purge pipes 11, and the inner wall of the purge pipe 11 is threaded with an extension pipe 12.

[0031] Specifically, the soil covering assembly improves the efficiency and quality of mulch film coverage during cotton seed covering and sowing through the coordinated operation of its various components. This avoids uneven mulch film coverage caused by uneven soil clods, thus improving cotton seed growth efficiency. The mounting frame 1 allows for quick connection between the soil covering equipment and the sowing equipment. As the sowing equipment moves forward, the equipment box 2 moves along with it. The cutting blades 5, in contact with the soil, cut and feed soil clods into the equipment box 2 during movement. Furthermore, the screening component separates large soil particles. The soil is screened out, and simultaneously, the suction machine 7 installed in the protective box 6 uses strong negative pressure suction to suck up the soil entering the equipment box 2. Then, the soil is quickly discharged above the mulch film through the discharge pipe 10. The soil pressure provides covering force for the mulch film, preventing it from being blown away by the wind and causing it to drift. The suction plate 9 increases the adsorption surface of the feed pipe 8, improving the efficiency of soil covering. The multiple blow pipes 11 on the outer wall of the discharge pipe 10 can use some airflow to blow from above the mulch film, improving the flatness of the mulch film and thus improving the overall covering quality of the mulch film.

[0032] The screening assembly includes a socket 13 fixedly connected to the inner wall of the equipment box 2, a screening plate 14 inserted into the inner wall of the socket 13, and a screen hole on the outer wall of the screening plate 14.

[0033] The screening assembly also includes a discharge baffle 16 rotatably connected to the bottom of the equipment box 2 via a rotating shaft 15, and a ratchet 17 fixedly sleeved on the outer wall of the rotating roller 4.

[0034] The cutting blade 5 is fixedly connected to a reset seat 18 on one side of the ratchet 17. A spring pawl 19 is slidably connected to the inner wall of the reset seat 18, and the outer wall of the spring pawl 19 abuts against the outer wall of the ratchet 17.

[0035] Specifically, by setting up the screening components, the screening plate 14 can be used to screen large particles in the soil clods, and then the discharge baffle 16 can be used to discharge excess particles. By cooperating with the reset seat 18 on the outer wall of the cutting blade 5, the spring pawl 19 and the ratchet 17 on the outer wall of the rotating roller 4, the cutting angle of the cutting blade 5 on the soil can be adjusted, thereby adjusting the amount of soil covering according to different thicknesses of mulch film, and further improving the versatility of soil covering.

[0036] Inside the equipment box 2, a support roller 20 is rotatably connected to one side of the cutting blade 5, and a feeding hopper 21 is rotatably sleeved on the outer wall of the support roller 20.

[0037] The outer wall of the equipment box 2 is equipped with a cover plate 22, and the outer wall of the cover plate 22 is equipped with a drive motor 23. The output end of the drive motor 23 is coaxially driven with the end of the support roller 20.

[0038] Specifically, by using the support rollers 20 on the inner wall of the equipment box 2 in conjunction with multiple feeding hoppers 21, and with the cooperation of the drive motor 23 on the outer wall of the cover plate 22, the rotating support rollers 20 drive the multiple feeding hoppers 21 to rotate, further impacting and conveying the soil entering the equipment box 2. This can improve both conveying efficiency and screening efficiency, thereby further improving the overall quality of the film covering.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
