Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Embodiment 1

[0028] A vegetable planting plastic film hole opener, as Figure 1 shown, includes a frame 1. The frame 1 is connected with wheels 3 through an adjustment component 2. A rotating shaft 5 is rotatably connected to the surface of the frame 1. The rotating shaft 5 is connected to the adjustment component 2 through a transmission component 8. A disc 4 is fixedly connected to the surface of the rotating shaft 5. A plurality of convex blocks 6 are detachably connected to the circumference of the surface of the disc 4;

[0029] The surface of the disc 4 and the convex blocks 6 cooperate with a telescopic component 7. One end of the telescopic component 7 is provided with a hole-opening rod 9.

[0030] During use, by pushing the frame 1, the wheels 3 drive the rotating shaft 5 to rotate through the adjustment component 2 and the transmission component 8, so that the disc 4 and the convex blocks 6 rotate. By utilizing the mutual cooperation between the telescopic component 7 and the convex blocks 6 and the disc 4, the hole-opening rod 9 moves up and down. By using the up and down movement of the hole-opening rod 9, the laid ground film is perforated.

[0031] In this device, by providing bumps 6 and a disc 4, the bumps 6 and the disc 4 are driven to rotate by the wheel 3, and then by the mutual cooperation between the telescopic assembly 7, the bumps 6 and the disc 4, the opening rod 9 moves up and down, thus achieving the technical effect of opening holes in the laid ground film, solving the problem that the electric heating sheet is prone to cause adhesion between the ground film and the equipment, and the defect that the entire ground film is pulled by the equipment.

[0032] As Figure 2 shown, the telescopic assembly 7 includes a fixed box 12 fixedly connected to the surface of the vehicle frame 1 and a connecting box 13 slidably connected to the inner surface of the fixed box 12. A support plate 11 is fixedly connected to the surface of the connecting box 13, and a round wheel 10 is rotatably connected to the side of the support plate 11;

[0033] One end of the connecting box 13 is fixedly connected to one end of the opening rod 9. The other end of the opening rod 9 passes through the surface of the fixed box 12, and the outer surface of the opening rod 9 is slidably fitted with the fixed box 12. A spring 14 is arranged on the outer side of the opening rod 9. One end of the spring 14 is fixedly connected to the surface of the connecting box 13, and the other end of the spring 14 is fixedly connected to the inner surface of the fixed box 12.

[0034] In this device, by providing the round wheel 10, and using the rotation of the round wheel 10 to cooperate with the surfaces of the disc 4 and the bumps 6, the friction between the telescopic assembly 7 and the disc 4 and the bumps 6 is reduced, and thus the damage to the surfaces of the disc 4 and the bumps 6 by the telescopic assembly 7 is reduced, thereby increasing the service life of the device.

[0035] The adjusting assembly 2 includes a round rod 15 fixedly connected to the side of the wheel 3 and a round barrel 16 rotatably connected to the vehicle frame 1. One end of the round rod 15 is movably inserted into the inner surface of the round barrel 16;

[0036] A plurality of pin holes 17 are linearly arranged on the surface of the round barrel 16, and through holes adapted to the pin holes 17 are arranged on the surface of the round rod 15;

[0037] A pin member 18 is inserted into the pin hole 17, and the pin member 18 passes through the pin hole 17 and the round rod 15.

[0038] In this device, by providing the round rod 15, the distance between the two wheels 3 can be adjusted by sliding the two round rods 15 in the round barrel 16. At the same time, by using the pin member 18 to connect the round rod 15 and the round barrel 16 together, the device can adjust the distance between the two opposite wheels 3 according to the width of the ground film, so that the wheels 3 will not damage the film, and at the same time, the applicability of the device is increased.

[0039] As Figure 4As shown, a plurality of threaded holes 19 are arranged in a circumferential array on the surface of the disc 4, and the bump 6 is fixedly connected to the threaded hole 19 through a bolt 20.

[0040] In this device, by arranging a plurality of threaded holes 19 on the surface of the disc 4, the number of bumps 6 fixed on the surface of the disc 4 can be adjusted, so that the number of times the punching rod 9 moves downward when the disc 4 rotates one circle can be adjusted, so that the distance between the holes in the plastic film can be adjusted, thereby further increasing the applicability of the device.

[0041] The transmission component 8 is any one of belt drive, chain drive and gear drive, and belt drive is preferably selected for this device.

[0042] Working principle: By pushing the vehicle frame 1 and utilizing the mutual cooperation between the wheels 3 and the ground, the wheels 3 drive the round rod 15 to rotate, thereby driving the round barrel 16 to rotate. The round barrel 16 drives the disc 4 and the bump 6 to rotate through the transmission component 8. By utilizing the mutual cooperation between the round wheel 10, the bump 6 and the disc 4, the round wheel 10 rotates and the elastic force of the spring 14 causes the connection box 13 to move up and down. By utilizing the up and down movement of the punching rod 9, holes are punched in the laid ground film.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
