In the mulching film covering operation, according to different crop types and agronomic requirements, parameters such as ditching depth, film laying position and soil covering width need to be adjusted. The functional components of the existing film-rolling and film-laying equipment are mostly connected in a welded or fixed manner, which can only realize local limited adjustment and is difficult to meet the rapid response requirements of various operation scenes on row spacing, film width and terrain changes.

[0034] The following will be described by referring to Figures 1 to 5 The technical solution of the present application will be further described.

[0035] A full-automatic film lifting and laying machine mainly comprises a frame body 1, a soil turning mechanism 2, a film lifting mechanism 3, a film laying mechanism 4 and a covering mechanism 5. The frame body 1 is welded by profile steel and constitutes the basic framework of the whole machine. A traction frame 11 is welded at the front end thereof, which is used to connect with the three-point suspension system of a tractor or other power machinery to provide traction power and lifting power for the whole machine.

[0036] The soil-turning mechanism 2 is symmetrically arranged on both sides of the front end of the frame body 1. The soil-turning mechanism 2 mainly comprises a furrow opener 21, a first moving plate 23 and a first mounting plate 24. A first limiting sleeve 22 is sleeved on the side longitudinal beam of the frame body 1, and the first mounting plate 24 is welded with the first limiting sleeve 22. By penetrating the first bolts (the bolt numbers are not shown in the figure, which can be in the form of stud and nut) of different heights, the first limiting sleeve 22 and the first mounting plate 24 thereon can be fastened at the required height position of the frame body 1, so as to realize the height coarse adjustment of the whole soil-turning mechanism 2. The first moving plate 23 is connected with the first mounting plate 24 through the second bolts (which can also be in the form of stud and nut).

[0037] A series of vertically arranged threaded holes are formed in the first moving plate 23, and a series of transversely arranged threaded holes are formed in the first mounting plate 24. By selecting different threaded hole combinations and tightening the second bolts, the height and transverse position of the first moving plate 23 relative to the first mounting plate 24 can be accurately adjusted, and then the soil penetration depth and transverse furrowing position (i.e. the working width) of the furrow opener 21 can be finally adjusted. The furrow opener 21 is fixed at the bottom end of the first moving plate 23 by welding.

[0038] The film-removing mechanism 3 is fixed on the middle beam of the frame body 1 through its mounting seat 31 and is located directly behind the soil-turning mechanism 2. The film-removing mechanism 3 is one of the core working components, mainly comprising a mounting seat 31, a cylinder 32, a connecting plate 33 and a film-removing body 34. The mounting seat 31 is fixed on the middle beam of the frame body 1 by bolts. The cylinder body end of the cylinder 32 is hinged to the mounting seat 31, and the piston rod end thereof is hinged to the connecting plate 33. By controlling the extension and contraction of the cylinder 32, the whole film-removing body 34 can be driven to rise and fall, so as to adjust the optimal winding operation depth according to the burial depth of the residual film in the soil.

[0039] The film-removing body 34 comprises a driving motor 341, a motor fixing frame 342, an electric push rod 343, a rotating plate 344 and a scraper 345. The driving motor 341 is fixed on the connecting plate 33 through the motor fixing frame 342. Its output shaft extends downward and is fixedly connected with the center of the rotating plate 344. A plurality of vertical rods 346 are uniformly distributed in a radial manner and are fixed perpendicularly at the bottom of the rotating plate 344. The bottom of the vertical rod 346 is tapered, which facilitates insertion into the soil and guides the winding of the residual film. When the driving motor 341 works, it drives the rotating plate 344 and all the vertical rods 346 to rotate together, and utilizes the rotating force to wind and collect the residual film on the vertical rods 346.

[0040] Two electric push rods 343 are provided in this embodiment, which are symmetrically vertically installed on both sides of the rotating plate 344. In other embodiments, the number of electric push rods 343 can be increased, and they are distributed at equal intervals around the central axis of the rotating plate 344. The push rod of the electric push rod 343 extends downward, and its end is connected with the scraper 345. The scraper 345 is provided with through holes corresponding in number and position to the vertical rods 346, and the vertical rods 346 pass through these through holes. When the residual film is wound to a certain amount, the electric push rod 343 is controlled to extend, pushing the scraper 345 to move downward along the vertical rod 346. By using the relative movement between the scraper 345 and the vertical rod 346, the wound residual film is stripped and falls off from the vertical rod 346, completing the film unloading.

[0041] The film laying mechanism 4 is installed above the frame body 1 through the first support assembly 12. The first support assembly 12 is in the shape of a rectangular frame, including two mutually parallel support plates 123 connected through a first telescopic rod 121 and a second telescopic rod 122. The first telescopic rod 121 and the second telescopic rod 122 can adopt a sleeve structure, and the length is fixed through a bolt hole or a threaded tightening method. By adjusting the length of the telescopic rod, the transverse span between the two support plates 123 can be changed to adapt to different width of the film roll.

[0042] The film laying mechanism 4 further includes a film cylinder support 41 and a film pressing mechanism 42.

[0043] The film cylinder support 41 is used to install the film roll, which is connected with the support plate 123 through an adjusting screw 124. One end of the adjusting screw 124 is hinged with the film cylinder support 41, and the other end passes through the hole on the support plate 123 and is locked by a nut. By loosening the nut and rotating the adjusting screw 124, the film cylinder support 41 can be driven to move along the support plate 123, so as to finely adjust the distance between the two film cylinder supports 41, and ensure accurate matching with the width of the film roll.

[0044] The film pressing mechanism 42 includes a film pressing roller 421, a second mounting plate 422 and a second moving plate 423. The second mounting plate 422 is welded on the second telescopic rod 122. The bottom of the second moving plate 423 is provided with an open slot 424, and the film pressing roller 421 is rotationally connected with the open slot 424. The second moving plate 423 is connected with the second mounting plate 422 through a third bolt. A plurality of groups of vertical threaded holes are formed on the second mounting plate 422 and the second moving plate 423. By selecting different threaded hole combinations and tightening the third bolt, the height of the second moving plate 423 and the film pressing roller 421 connected at the lower end thereof from the ground can be adjusted, so as to ensure that the film pressing roller 421 can always be in close contact with the ground with appropriate pressure, and the film can be flattened and pressed.

[0045] The covering mechanism 5 is installed at the lower rear of the frame body 1 through a second support assembly 13. The second support assembly 13 comprises a "C-shaped" second support 131, the front end of which is connected with a first support seat 132 welded on the frame body 1 through a fourth bolt. The lateral position of the second support 131 can be adjusted as a whole by loosening the fourth bolt. The rear end of the second support 131 is welded with a second support seat 133.

[0046] The covering mechanism 5 mainly comprises a covering disc plough 51, a third moving plate 52 and a film pressing wheel 53. The third moving plate 52 is connected with the second support seat 133 through a fifth bolt. A plurality of groups of thread holes arranged laterally are formed in the second support seat 133, and the lateral working position of the third moving plate 52 and the whole covering part can be adjusted by selecting different hole positions and tightening the fifth bolt. The film pressing wheel 53 is connected with the lower end of the third moving plate 52 through a spring shock absorber 54. The spring shock absorber 54 can effectively absorb the impact caused by uneven ground and keep the film pressing wheel 53 stable. The covering disc plough 51 is connected with the tail end of the third moving plate 52 through a disc plough adjusting rod 55. The disc plough adjusting rod 55 is provided with a scale (not shown in the figure) and is fixed on the third moving plate 52 through a second limiting sleeve 56 and a locking bolt. By loosening the locking bolt, the depth of the covering disc plough 51 can be adjusted by moving the disc plough adjusting rod 55 up and down, and the deflection angle of the covering disc plough 51 can be adjusted by swinging the disc plough adjusting rod 55 left and right, so as to control the covering amount and the covering direction.

[0047] Working principle:

[0048] During operation, the tractor pulls the whole machine forward. First, the furrow plough 21 on the two sides of the soil turning mechanism 2 breaks the soil and opens the ditch. Then, the film lifting mechanism 3 behind is lowered to the set depth, the rotating vertical rod 346 rolls up the residual old film in the field and peels off the residual film through the timing action of the scraper 345. After completing the residual film cleaning, the film laying operation is carried out, the new film roll is unfolded by the film laying mechanism 4, and the new film is flattened and laid on the cleaned field surface by the film pressing roller 421. Finally, the film pressing wheel 53 of the covering mechanism 5 presses the edges of the film on both sides, the soil is turned up by the covering disc plough 51 and covered on the edges of the film, and the covering and film pressing operation is completed. The parameters of all mechanisms can be quickly adjusted according to the actual situation in the field through the above bolt connection structure and adjusting device, so as to realize efficient and high-quality integrated operation.

[0049] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
