[0028] Please see Figures 1-5 This utility model provides a crop planting film pressing mechanism, including a connecting beam 1, multiple limiting plates 2 fixedly disposed on the lower side of the connecting beam 1, and multiple film pressing components. The film pressing components include a film pressing bracket 3 and a film pressing roller 4 rotatably disposed on the film pressing bracket 3. The film pressing bracket 3 is correspondingly disposed with the limiting plate 2 and is elastically connected to the limiting plate 2. Even if the field is uneven, the film pressing bracket 3 will adaptively adjust, enabling the film pressing roller 4 to easily cope with uneven field conditions. This makes the mechanism more adaptable to field operations, allows the mulch film 20 to adhere better to the field, and the multiple film pressing components can improve work efficiency. The number of film pressing components can be increased or decreased according to the number of rows of crops, making it more widely applicable to various types of fields.

[0029] like Figures 1-5 As shown, a rotating shaft 401 is inserted into the pressing roller 4, and the rotating shaft 401 is rotatably connected to the pressing bracket 3.

[0030] like Figures 1-5 As shown, the pressure film support 3 is provided with a guide rod 5 along the vertical direction, and the limiting plate 2 is provided with at least one guide hole (not shown) that passes through it vertically. The guide rod 5 is movably inserted into the guide hole. The guide rod 5 and the pressure film support 3 are connected by welding, threading, or locking plates. The cooperation between the guide rod 5 and the guide hole makes the pressure roller support more stable when compressing the elastic element 6, and has a guiding effect on the pressure film roller 4.

[0031] like Figures 1-5 As shown, the guide rod 5 is fitted with an elastic element 6, which is located between the limiting plate 2 and the pressure film bracket 3. Specifically, the elastic element 6 is a spring, and the guide rod 5 cooperates with the elastic element 6, so that the spring has good compression guidance.

[0032] like Figures 1-5 As shown, the pressure film support 3 is detachably inserted with at least one limiting rod 7 along the vertical direction, and the limiting plate 2 is provided with at least one limiting hole 201 that passes through it vertically. The limiting rod 7 is movably inserted with the limiting hole 201. Specifically, each limiting plate 2 has four limiting rods 7 and four limiting holes 201. The limiting rod 7 is a limiting bolt. The nut of the limiting bolt abuts against the limiting plate 2 to form a limit, preventing the guide rod 5 from disengaging from the limiting plate 2, and also serving to connect the limiting plate 2 and the pressure roller support.

[0033] like Figures 1-5 As shown, a guide sleeve 8 is fixedly provided on the upper side of the limiting plate 2, and the guide rod 5 is movably inserted into the guide sleeve 8. Further, as a preferred technical solution, there are two guide rods 5, and each guide rod 5 is fitted with one guide sleeve 8. The connecting beam 1 is located between the two guide sleeves 8. The guide sleeves 8 guide the guide rods 5, further improving the guiding effect. During installation, the guide sleeves 8 also play a positioning role for the connecting beam 1.

[0034] like Figures 1-5 As shown, the limiting rod 7 is detachably connected to the pressure film bracket 3 via a nut 9, which can lock the limiting rod 7 and the pressure film bracket 3.

[0035] like Figures 1-5 As shown, the connecting beam 1 is a C-shaped tube, which is lightweight, simple in structure, and easy to select.

[0036] like Figures 1-5As shown, a connecting rod 101 is vertically arranged on each side of the connecting beam 1. Specifically, a film cutting and film topping device is installed on the frame of the mulching agricultural machinery. The film cutting and film topping device includes a main beam 10, two fixed supports 11 respectively arranged at both ends of the main beam 10, a flipping rod 12 rotatably arranged on the fixed supports 11, a flipping telescopic device 13 with a flipping piston rod 1301, a mounting frame 14 fixedly arranged on the flipping rod 12, a film cutting telescopic device 15 with a film cutting piston rod 1501 arranged on the mounting frame 14, and a film topping telescopic device with a film topping telescopic rod arranged on the mounting frame 14. 16. The top film blade 18 and the film cutting blade 17 are located between the two mounting frames 14. One end of the flip telescopic device 13 is rotatably connected to the fixed bracket 11. One end of the flip piston rod 1301 is rotatably connected to the flip rod 12 through the connecting frame 19. One end of the film cutting piston rod 1501 is connected to the film cutting blade 17. One end of the top film piston rod 1601 is connected to the top film blade 18. Two mounting plates 1401 are fixedly installed on the lower side of each mounting frame 14. The two ends of the connecting rod 101 are respectively connected to the two mounting plates 1401 on the same side. The connection method is reasonable and makes reasonable use of the installation space.

[0037] like Figures 1-5 As shown, the overturning telescopic device 13, the film cutting telescopic device 15, and the top film telescopic device 16 are driving devices such as telescopic cylinders, telescopic electric cylinders, and telescopic hydraulic cylinders. The specific operation process is as follows: the overturning telescopic device 13 drives the overturning piston rod 1301 to extend, and the overturning rod 12 flips downward, so that the film cutting knife 17 is approximately perpendicular to the mulch film 20. The film cutting telescopic device 15 drives the film cutting piston rod 1501 to extend, and the film cutting knife 17 descends to cut the mulch film 20. At this time, the top film piston rod 1601 is in the retracted state.

[0038] After the film cutting is completed, the film cutting telescopic device 15 drives the film cutting piston rod 1501 to retract, the top film telescopic device 16 drives the top film piston rod 1601 to extend, and the top film blade 18 descends to press the mulch film 20 into the field. After the top film is completed, the top film telescopic device 16 drives the top film piston rod 1601 to retract, and the pressing roller 4 continues to roll the mulch film 20. The cooperation of the top film and the pressing film makes the mulch film 20 adhere better to the field.

[0039] The above embodiments are merely descriptions for clearly illustrating the present utility model, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here, and the obvious variations or modifications derived therefrom are still within the protection scope of the present utility model.
