[0035] Embodiment 1

[0036] Referring to the attached drawings Figures 1 - 3 As shown, an agricultural ridging and film covering machine includes:

[0037] A U-shaped bracket 10, both ends of one side of the U-shaped bracket 10 are fixedly connected with cross bars 11, the ends of the two cross bars 11 are fixedly connected with a connecting rod 12, the bottom of the connecting rod 12 is fixedly connected with two connecting plates 14, the U-shaped bracket 10, the cross bars 11 and the connecting rod 12 together form a support structure, the bottom of the cross bars 11 are all provided with film pressing wheels 13, and one side of the connecting plate 14 is fixedly connected with a soil covering wheel 15 for turning the soil.

[0038] An earth-opening component 20 arranged at the bottom of the U-shaped bracket 10 for pushing and leveling the ground at the film covering place;

[0039] A film covering component 30 fixedly arranged at the bottom of the U-shaped bracket 10 and on one side of the earth-opening component 20 for covering the film on the ground after earth-opening;

[0040] A pressing and covering component 40 arranged on one side of the film covering component 30, the pressing and covering component 40 includes a film pressing unit and a telescopic unit, the film pressing unit includes a driver and a pressing and cutting structure, the driver works to drive the pressing and cutting structure to press and cut the film covering place, and the telescopic unit works to drive the pressing and cutting structure to contact the ground and the telescopic unit can achieve a length change in the horizontal direction.

[0041] In the initial state, the pressing component 40 does not contact the ground. When the device starts to work, the film pressing unit is placed on the ground through the telescopic unit to press against the film unfolded on the film covering component 30. Then, through the operation of the driver, the pressing and cutting structure is driven to firmly press the film. As the device moves forward, the soil-opening component 20 at the front end of the device levels the soil on the walking route. At this time, on the premise that one end of the unfolded film is pressed, the film gradually unfolds following the movement of the device. The film pressing wheels 13 run on the surfaces on both sides of the film to achieve pressing. At the same time, the soil covering wheels 15 push the soil pushed flat onto the film to achieve covering. After moving a certain distance, there is enough soil of sufficient weight on the film surface to ensure that the film will unfold when the device moves rather than move with the device, thereby realizing the film covering operation, which enables the operator not to manually step on the film when the machine starts, simplifies the operation process, improves the convenience and efficiency of the operation, greatly reduces the dependence on labor, reduces the labor intensity, and improves the work efficiency;

[0042] After covering one row of land, only need to repeat the operations when the device starts to work as described above to cut the film covering the ground, eliminating the step of the operator manually cutting the film after the operation is completed, reducing the labor intensity and operation complexity.

[0043] The telescopic unit includes two sleeves 41 rotatably connected to one side of the connecting rod 12. Support rods 42 are slidably arranged inside the sleeves 41. An electric telescopic rod 43 is rotatably installed on one side of the connecting plate 14. The piston rod of the electric telescopic rod 43 is rotatably connected to the bottom of the sleeve 41. The support rod 42 can freely slide inside the sleeve 41. When the electric telescopic rod 43 extends, the sleeve 41 will tilt upward. At this time, the support rod 42 will automatically slide into the inside of the support rod 42, facilitating the retraction of the support rod 42 after the pressing is completed.

[0044] The pressing and cutting structure includes a cross plate 44 fixedly connected to one end of the support rod 42. The driver includes a cylinder 45 fixedly installed on the top of the cross plate 44. The piston rod of the cylinder 45 penetrates the cross plate 44 and its end is fixedly connected to a pressing plate 46.

At the beginning stage of the work, by controlling the operation of the cylinder 45, the pressing plate 46 is driven to move, thereby pressing the film covering the ground. At the same time, the cutting knife 48 cuts the excess part on the outside. At the end stage of the work, the cylinder 45 is controlled to work again, so that the cutting knife 48 cuts the film.

[0045] The film covering assembly 30 includes two roller frames 31 fixedly connected to the bottom of the U-shaped bracket 10. A film roller 32 is rotatably arranged between the two roller frames 31.

The upper part of the roller frame 31 is arranged in an open structure, and the film roller 32 can be taken out from the roller frame 31, which is convenient for replacing the plastic film 33.

[0046] The soil opening assembly 20 includes a connecting rod 21 fixedly connected to the bottom of the U-shaped bracket 10 and located between the two roller frames 31. A soil leveling plate 22 is fixedly connected to the bottom of the connecting rod 21. When the device is moving, the soil leveling plate 22 will level the soil on the walking path, which is convenient for film covering. And after pushing the soil to both sides of the device, it is convenient for subsequent pressing of the film.

[0047] The distance between the two soil covering wheels 15 is greater than the distance between the two film pressing wheels 13 and greater than the width of the plastic film 33. The width of the plastic film 33 is greater than the distance between the two film pressing wheels 13. The film pressing wheels 13 walk on the surfaces on both sides of the plastic film 33 to press the plastic film 33 tightly, while the soil covering wheels 15 scrape the soil on both sides onto the surface of the plastic film 33 to press the plastic film 33.
