[0030] Embodiment 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model proposes an agricultural film covering device with automatic cutting effect. Compared with the first embodiment, as another embodiment of the utility model, the outer wall of the device body 1 is provided with a hand wheel 3, one end of the hand wheel 3 is fixedly connected with a worm 31 rotatably connected to the inner wall of the device body 1, the outer wall of the worm 31 is meshed with a worm wheel 32 rotatably connected to the inner wall of the device body 1, the rotation center of the worm wheel 32 is fixedly connected with a swing rod 33 through a connecting shaft, the outer wall of the swing rod 33 is slidably connected with a limit block 34 slidably connected to the outer wall of the device body 1, the outer wall of the limit block 34 is fixedly connected with a telescopic rod 37 telescopically connected to the outer wall of the device body 1, and the telescopic rod 37 is provided to facilitate when passing through When the film covering equipment is covering crops, in order to improve the convenience of adjusting the height of the smoothing roller 14 and improve the film covering effect on the ground at different heights, the hand wheel 3 can be turned to drive the worm wheel 32 to rotate through the rotation of the worm 31 according to the required film covering height. The rotation of the worm wheel 32 drives the limit block 34 to slide along the outer wall of the limit groove 35 through the rotation of the swing rod 33. At the same time, the limit block 34 slides along the outer wall of the fixed groove 36. The sliding of the limit block 34 drives the connecting rod 13 to retract through the extension and retraction of the telescopic rod 37, thereby adjusting the height of the smoothing roller 14, thereby realizing the control operation of improving the film covering effect on the ground at different heights when the film covering equipment is used to cover crops.

[0032] Furthermore, a limiting groove 35 is provided at the connection position between the outer wall of the swing rod 33 and the limiting block 34, a fixing groove 36 is provided at the connection position between the outer wall of the equipment body 1 and the limiting block 34, and a telescopic groove is provided at the connection position between the outer wall of the equipment body 1 and the telescopic rod 37. The limiting block 34 forms a sliding structure between the swing rod 33 and the fixing groove 36, which is beneficial to the rotation of the swing rod 33, driving the limiting block 34 to slide along the outer wall of the limiting groove 35, and at the same time slide along the outer wall of the fixing groove 36, thereby realizing the control operation of extending and retracting the telescopic rod 37.

[0033] Furthermore, two groups of worm wheels 32 are provided, and the rotation directions of the two groups of worm wheels 32 are opposite. The rotation center of the swing rod 33 and the rotation center of the worm wheel 32 are arranged to coincide with each other. The swing rod 33 forms a rotating structure with the device body 1 through the worm 31 and the worm wheel 32, which is conducive to the rotation of the worm 31 to drive the swing rod 33 to rotate through the rotation of the worm wheel 32, thereby realizing the sliding control operation of the limit block 34.

[0035] Working principle: When using this agricultural film covering equipment with automatic cutting effect, first, after the crops are covered with film by the film covering equipment, in order to improve the positioning effect of the ground film 12 after cutting and prevent the source of the ground film 12 from being found when the ground film 12 is used next time, the driving motor 2 can be turned on to rotate the threaded rod 21 to drive the blade 22 to slide along the outer wall of the slide groove 23, so that the two sets of blades 22 clamp and fix the ground film 12, thereby realizing the control operation of improving the positioning effect of the ground film 12 after cutting after the crops are covered with film by the film covering equipment.

[0036] Secondly, after the crops are covered with film by the covering equipment, in order to improve the automatic cutting effect of the ground film 12, there is no need for the staff to manually cut the ground film 12, thereby reducing the workload of the staff. The driving motor 2 can be turned on to rotate the threaded rod 21 to drive the blade 22 to slide along the outer wall of the slide groove 23, so that the two sets of blades 22 are close to each other to cut the ground film 12, thereby realizing the control operation of improving the automatic cutting effect of the ground film 12 after the crops are covered with film by the covering equipment.

[0037] Again, when the crops are covered with film by the covering equipment, in order to improve the convenience of adjusting the height of the smoothing roller 14 and improve the covering effect on the ground at different heights, the hand wheel 3 can be turned to drive the worm wheel 32 to rotate through the rotation of the worm 31 according to the required covering height. The rotation of the worm wheel 32 drives the limit block 34 to slide along the outer wall of the limit groove 35 through the rotation of the swing rod 33. At the same time, the limit block 34 slides along the outer wall of the fixed groove 36. The sliding of the limit block 34 drives the connecting rod 13 to retract through the extension and retraction of the telescopic rod 37, thereby adjusting the height of the smoothing roller 14, thereby realizing the control operation of improving the covering effect on the ground at different heights when the crops are covered with film by the covering equipment.

[0038] Finally, when the film covering equipment is covering crops, the height of the smoothing roller 14 can be adjusted first, and then the ground film 12 can be placed under the smoothing roller 14, and then the equipment can be moved. Through the movement of the equipment, the smoothing roller 14 can be driven to smooth the ground film 12 to prevent wrinkles from appearing during the covering process of the ground film 12, resulting in incomplete coverage. Through the movement of the equipment, the flattening roller 15 can be driven to press the two sides of the ground film 12, and then through the rotation of the soil-turning roller 16, the soil covers both sides of the ground film 12, thereby fixing the ground film 12.

[0039] This is how this agricultural film covering device with automatic cutting effect works.

[0040] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms.
