[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] See also Figure 1-4 , a technical solution provided by an embodiment of the utility model: the portable electric film breaker includes a fixed plate 17 fixedly connected in the cylinder 1, a rotating rod 16 rotatably and slidably connected to the fixed plate 17, a film breaker cylinder 2 is sleeved on the rotating rod 16, a barb 18 is provided at the bottom end of the rotating rod 16, a movable plate 12 is provided at the top of the rotating rod 16, an elastic unit is provided between the movable plate 12 and the fixed plate 17, a first bevel gear 9 is horizontally rotatably connected in the cylinder 1, a second bevel gear 10 meshing with the first bevel gear 9 is vertically rotatably connected in the cylinder 1, one end of the second bevel gear 10 is coaxially fixedly connected with a cam 11, the elastic force of the elastic unit causes the movable plate 12 to abut against the peripheral side of the cam 11, a motor 7 is provided in the cylinder 1, the first bevel gear 9 is sleeved on the output shaft 8 of the motor 7, and the rotating rod 16 is slidably sleeved on the output shaft 8 of the motor 7, specifically, a switch 6 is provided on the top of the cylinder 1, and the switch 6 is electrically connected to the motor 7.

[0021] As a preferred technical solution, the elastic unit includes a spring 15, which is sleeved on a rotating rod 16. The two ends of the spring 15 are respectively fixedly connected to the movable plate 12 and the fixed plate 17. Specifically, during the rotation of the cam 11, the movable plate 12 is pushed, and the elastic potential energy of the spring 15 causes the movable plate 12 to drive the rotating rod 16 to rise and fall vertically, thereby cutting the ground film and causing the barbs 18 to rise and fall vertically to hook the residual film after cutting.

[0022] As a preferred technical solution, the bottom end of the film breaking cylinder 2 is provided with a plurality of saw teeth 3 in a circular array. Specifically, the rotating rod 16 rotates to cause the saw teeth 3 at the lower part of the film breaking cylinder 2 to rotate around the central axis of the cylinder body 1. The saw teeth 3 scratch through the ground film so that a hole is scratched in the ground film, so that the cut part of the ground film is completely separated from the other parts of the ground film instead of being pressed into the soil, which will not cause the hole wall to be covered by the ground film and cause the nutrients of the seedlings to be blocked by the ground film.

[0023] As a preferred technical solution, a slide groove 13 is vertically opened in the rotating rod 16, and a slider 14 is fixedly connected to the peripheral side of the output shaft 8 of the motor 7, and the slider 14 is slidably connected in the slide groove 13. Specifically, by the peripheral side of the slider 14 being in contact with the slide groove 13, the output shaft 8 of the motor 7 can drive the rotating rod 16 to rotate, and by the slider 14 sliding vertically in the slide groove 13, the rotating rod 16 and the output shaft 8 of the motor 7 can produce relative movement in the vertical direction, so that the rotating rod 16 is movably connected in the cylinder 1, and drives the barb 18 and the membrane breaking cylinder 2 to slide and rotate synchronously.

[0024] As a preferred technical solution, two handles 4 are symmetrically provided on the circumferential side of the cylinder body 1, and an anti-slip sleeve 5 is sleeved on the two handles 4. Specifically, the anti-slip sleeve 5 increases the friction between the operator's hands and the handles 4, and the symmetrically arranged handles 4 make it more convenient for the operator to hold the device.

[0025] Working principle: The portable electric film breaker starts the motor 7 to drive the first bevel gear 9 to rotate, and the second bevel gear 10 is rotated through the meshing transmission of the first bevel gear 9, and the second bevel gear 10 drives the cam 11 to rotate. Through the rotation of the cam 11, the change in the rotation diameter of the cam 11 and the action of the spring 15 on the movable plate 12 make the rotating rod 16 continuously reciprocate up and down during the rotation process, and the film breaker cylinder 2 punches holes in the ground film. After the film is broken, the barbs 18 can hook the cut ground film and wrap it around the rotating rod 16, which is convenient for subsequent cleaning. No manual cleaning is required, thus avoiding white pollution to farmland.

[0026] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
