[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 The present invention provides a technical solution: A mulching device for vegetable cultivation includes a main frame 1. A crossbar 2 and a tail frame 3 are fixedly connected to the front and rear ends of the main frame 1, respectively. The crossbar 2 is vertically connected to the main frame 1 at the middle position, and the connection position is at the front end of the main frame 1. Adjusting arms 5 are connected to both ends of the crossbar 2. The lower end of the adjusting arm 5 is rotatably connected to a movable wheel 6 through a rotating shaft 22. A motor 21 is fixedly connected to one side of the adjusting arm 5. The motor 21 drives the rotating shaft 22 to rotate through a belt 23. After the motor 21 is started, it can drive the movable wheel 6 to rotate, so that the mulching device can move along the field. A T-shaped frame 33 is connected to the main frame 1. A bending frame 34 is slidably connected to both ends of the T-shaped frame 33. An adjusting arm 5 is connected to the bending frame 34 through a transmission frame 26. A separating shovel 8 is connected to the lower end of the bending frame 34. The separating shovel 8 consists of a rod-shaped structure at the upper end and a shovel-shaped structure at the lower end. The separating shovel 8 can shovel the soil clods on the field to both sides of the field to ensure that the subsequent push frame 9 can push enough soil clods so that the soil clods can be re-buried on both sides of the new plastic film. A connecting frame 13 is connected to the main frame 1. A film rolling roller 14 is rotatably connected to the connecting frame 13. The new plastic film to be covered is wound on the film rolling roller 14. The rotation of the film rolling roller 14 mainly relies on the traction of the new plastic film so that the new plastic film is covered on the field. A driven wheel 7 is rotatably connected to the tail frame 3. The driven wheel 7 rotates by being driven by the moving wheel 6. A guide frame 36 and a push frame 9 are connected to the front and rear of the tail frame 3, respectively. A recycling mechanism for recycling waste plastic film on the field is connected to one side of the crossbar 2.

[0020] Specifically, such as Figure 2 As shown, the upper end of the adjusting arm 5 is slidably sleeved on the crossbar 2. There are two sets of adjusting arms 5. An adjusting component is provided between the adjusting arms 5 to adjust the distance between the adjusting arms 5. The distance between the moving wheels 6 can be adjusted by the adjusting component, so as to adapt to different field row spacing.

[0021] Specifically, such as Figure 6 As shown, the adjusting component includes a turntable 27, which is fixedly connected to a gear 30 via a shaft. The turntable 27 and the gear 30 are rotatably connected to the upper and lower sides of the crossbar 2 via shafts, respectively. A traction bar 28 is eccentrically rotatably connected to the lower surface of the turntable 27. The other end of the traction bar 28 is rotatably connected to one side of the adjusting arm 5. When the turntable 27 rotates, it can pull the adjusting arm 5 closer to or further away from each other in conjunction with the traction bar 28.

[0022] Specifically, such as Figure 7 As shown, a crank handle 29 is connected to the upper end of gear 30. The crank handle 29 is designed to facilitate the operation of gear 30 rotation. A locking block 31 is rotatably connected to the crossbar 2. One end of the locking block 31 is locked onto gear 30. A spring 32 is connected between the locking block 31 and the crossbar 2. The spring 32 can ensure that the locking block 31 is locked onto gear 30. When the locking block 31 is driven to deflect upward, the elastic force of the spring 32 needs to be overcome.

[0023] Specifically, such as Figure 8 As shown, the lower end of the bending frame 34 is sleeved on the outside of the separating shovel 8. A connecting wheel 35 is threaded onto the bending frame 34. One end of the connecting wheel 35 abuts against the outside of the separating shovel 8 inside the bending frame 34. The connecting wheel 35 is tightened onto the bending frame 34. At this time, one end of the connecting wheel 35 abuts against the outside of the upper rod-shaped structure of the separating shovel 8, thereby fixing the separating shovel 8. Before fixing, the separating shovel 8 can be easily adjusted to rotate and change the orientation angle of the separating shovel 8. The transmission frame 26 enables the separating shovel 8 to move synchronously along the T-shaped frame 33 when the adjusting arm 5 moves along the crossbar 2, ensuring that the separating shovel 8 can also be synchronously adapted to the row spacing of the field.

[0024] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the recycling mechanism includes a winding rod 11, a top frame 4 connected to one side of the main frame 1, a slide 10 for the winding rod 11 to slide on the top frame 4, and a guide frame 12 connected to one end of the slide 10 for guiding the waste plastic film to be rolled up. Through the guide frame 12, the waste plastic film can be stably rolled up onto the winding rod 11. A rotating shaft 22 is rotatably connected to a wheel frame 25 via a bearing. A wheel frame 25 is rotatably connected to a transfer wheel 24 via a bearing. A transfer wheel 24 is rotatably connected to another wheel frame 25 via a bearing. The other wheel frame 25 is rotatably connected to the winding rod 11 via a bearing. There are two sets of wheel frames 25. The two sets of wheel frames 25 correspond to the connection between the rotating shaft 22 and the transfer wheel 24, and between the transfer wheel 24 and the connecting wheel 15, respectively. The wheel frame 25 can stabilize the distance between the rotating structures. The bearings connected at the rotating position of the wheel frame 25 are to reduce structural wear. Multi-stage transmission is achieved through the transfer wheel 24, so that the horizontal position of the winding rod 11 can be freely adjusted without changing the transmission ratio, which is suitable for the constantly changing winding diameter during the recycling of waste plastic film. A belt 23 is connected between the rotating shaft 22 and the transfer wheel 24. The transfer wheel 24 is connected to the connecting wheel 15 via another belt 23. The connecting wheel 15 is fixedly connected to the winding rod 11. When adjusting the spacing of the adjusting arm 5, it can simultaneously drive the winding rod 11 to slide on the slide 10 along the direction of the crossbar 2.

[0025] Specifically, such as Figure 3 As shown, a pressure groove 17 is provided on the winding rod 11, and a pressure strip 16 for clamping and limiting the waste mulch film is connected in the pressure groove 17. By setting the pressure groove 17 and the pressure strip 16 to cooperate with each other, it is ensured that one end of the waste mulch film can be fixed before recycling before the new mulch film is covered, and that the waste mulch film can be stably wound on the winding rod 11.

[0026] Specifically, such as Figure 3As shown, a pull rod 19 is slidably connected to the top frame 4. One end of the pull rod 19 is connected to a sleeve 18 that is sleeved on the outside of the winding rod 11. A spring 20 is connected between the sleeve 18 and the top frame 4 to pull the sleeve 18. By setting the spring 20, the winding rod 11 can be pulled to abut against one end of the slide 10. As the winding and recycling proceeds, the waste plastic film can overcome the elastic force of the spring 20 and pull the winding rod 11 to slide on the slide 10. After the waste plastic film recycling is completed, the spring 20 can also pull the winding rod 11 to reset.

[0027] In summary, the mulching device for vegetable cultivation provided in this embodiment allows for the following process: When mulching a field, the mulching device is moved to one end of the field, the locking block 31 is moved to release the limit on the crank handle 29, and then the crank handle 29 is turned to drive the turntable 27 to rotate. The traction bar 28, which is eccentrically connected to the turntable 27, drives the adjusting arm 5 to move along the crossbar 2, so that the distance between the two adjusting arms 5 is adapted to the row spacing of the field. In contrast, traditional mulching devices can only adapt to fixed-size row spacing mulching. After adjustment, the locking block 31 is released, and the spring 2 32 pulls the locking block 31 to re-limit the gear 30, preventing the gear 30 from rotating during the operation of the mulching device.

[0028] When adjusting the spacing of the adjusting arm 5, the transmission frame 26 connected to one side of the adjusting arm 5 can drive the bending frame 34 to slide on the T-shaped frame 33. The upper end of the bending frame 34 is a sleeve structure, which is sleeved on the T-shaped frame 33, while the lower end of the bending frame 34 is a round tube structure. Therefore, while the adjusting arm 5 moves along the crossbar 2, the bending frame 34 will also move on the T-shaped frame 33 at the same time, thereby driving the separating shovel 8 at the lower end of the bending frame 34 to move, ensuring that the separating shovel 8 can also adapt to the mulching requirements of different ridge spacing fields.

[0029] The separating shovel 8 is fixed to the lower end of the bending frame 34 by the abutment wheel 35. The angle of the lower end of the separating shovel 8 can be changed by rotating the separating shovel 8. The separating shovel 8 can guide the soil on the field to the ditch, which is convenient for the subsequent laying of mulch film and burying on both sides.

[0030] The tail frame 3 is connected to the tail end of the main frame 1. Two sets of driven wheels 7 are rotatably connected to the tail frame 3. The driven wheels 7 can slide on the tail frame 3 to adjust the distance between the driven wheels 7 to adapt to different field row spacing. Two sets of guide frames 36 are symmetrically arranged on the side of the tail frame 3 facing the film rolling roller 14. The guide frame 36 has an arc-shaped structure, which can guide the mulch film to be laid on the field without damaging the mulch film. On the side of the tail frame 3 away from the film rolling roller 14, two sets of push frames 9 are symmetrically arranged. The push frames 9 can push the soil clods scooped up by the separating shovel 8 back to both sides of the mulch film, thereby stabilizing the mulch film laying structure. The push frame 9 consists of the lowest inclined plate and the connecting structure connecting the inclined plate to the tail frame 3. The inclined plate is in an inclined state. As the mulching device moves, it can push the soil clods with the matching inclined plate to complete the burial of both sides of the mulch film.

[0031] Before mulching, one end of the waste plastic film in the field can be clipped onto the winding rod 11, and the pressure strip 16 can be inserted into the pressure groove 17 to fix the waste plastic film onto the winding rod 11. When the mulching device moves on the field, the motor 21 drives the moving wheel 6 to rotate through the belt 23. The moving wheel 6 drives the connecting wheel 15 to rotate through the transfer wheel 24, so that the winding rod 11 can rotate automatically when the device moves, so that the waste plastic film is wrapped around the winding rod 11 and the recycling is completed.

[0032] As the amount of waste plastic film wrapped on the winding rod 11 increases, the length of the recycled waste plastic film increases with each rotation of the winding rod 11. At this point, the moving speed of the device cannot keep up with the recycling of the waste plastic film. Through the traction of the waste plastic film, the winding rod 11 can be moved away from the adjusting arm 5, the spring-20 structure is stretched, and the winding rod 11 slides forward on the slide 10. This recycling mechanism enables the recycling of waste plastic film at the same time when new plastic film is applied, avoiding soil pollution and improving the efficiency of new plastic film application.

[0033] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
