[0024] In one embodiment, two groups of pillars 14 and bulldozers 15 are provided, and the two groups of pillars 14 and bulldozers 15 are symmetrical about the vertical center line of the film covering frame 1. The bulldozers 15 are arc-shaped as a whole, and the bulldozers 15 are narrow in front and wide in the back, and the surface of the bulldozers 15 is provided with an arc surface 20. The narrower end of the bulldozers 15 faces the movable plate 3. Through the setting of the bulldozers 15, the soil can be gathered to the middle, so that the soil can be easily pushed to the edge of the film without the need for manual sealing.

[0025] In one embodiment, the cross-sections of the guide block 4 and the guide groove 5 are both T-shaped structures, and anti-slip grooves are provided between the guide block 4 and the guide groove 5. The anti-slip groove structure can be grid-shaped, which can easily increase the friction between the guide block 4 and the guide groove 5 and prevent the movable plate 3 from undergoing large displacement.

[0026] In one embodiment, the threaded column 17 is vertically arranged relative to the horizontal plate 6, and the diagonal support 7 is inclined relative to the threaded column 17. Through the arrangement of the diagonal support 7, the pressure wheel 13 of the diagonal support 7 can be rolled and connected with the edge of the unrolled film, which is convenient for guiding the film and preventing it from being blown by side wind.

[0027] In one embodiment, the handle 2 is tilted relative to the laminating frame 1, and the handle 2 is composed of a U-shaped steel frame and a rubber sleeve sleeved in the middle. The setting of the handle 2 can assist the laminating frame 1 in moving, which can easily increase the laminating effect.

[0028] In one embodiment, the cross section of the positioning shell 11 is U-shaped, and screw holes are provided on both sides of the positioning shell 11 corresponding to the plum blossom knob 12. The arrangement of the positioning shell 11 facilitates locking of the roller shaft of the laminating roller 9.

[0029] Working principle:

[0030] When in use, first connect the traction frame 16 on the top of the film covering frame 1 to the external tractor tail, then place the film covering roller 9 that meets the coffee planting gap size between the two movable plates 3 of the film covering frame 1, and move the two movable plates 3 toward and away from each other, so that the positioning shells 11 installed on the opposite surfaces of the two movable plates 3 using the rotating column 10 are gradually close to the film covering roller 9, so that the roller shaft of the film covering roller 9 extends into the positioning shell 11 until the plum blossom knobs 12 screwed on both sides of the positioning shell 11 are against the side of the roller shaft of the film covering roller 9, thereby locking the film covering roller 9. The film covering frame 1 is driven to move, so that the film on the surface of the film covering roller 9 is unwound until the film is laid on the planting area of ​​the coffee seeds. In this process, by adjusting the position of the threaded column 17 in the oblong hole 19, the diagonal support 7 connected to the threaded column 17 is prompted to adjust its position accordingly, so that the pressure wheel 13 at the bottom of the diagonal support 7 can be rolled to guide the edge of the unwound film, which is convenient for film covering while preventing the film from being blown by the side wind. The bulldozers 15 arranged on both sides of the tail of the film covering frame 1 push the soil to the edge of the film during the walking stage, so that the soil is covered on the edge of the film, thereby increasing the coating effect of coffee planting.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
