Technical Field
[0001] This utility model relates to the field of mulched soil compactor technology, and in particular to a soil diversion device for a mulched soil compactor. Background Technology
[0002] A mulching and compaction machine is an agricultural machine primarily used in farmland operations to integrate the laying of mulch film with soil compaction. By covering the soil surface with a film and compacting the edges, it achieves functions such as heat preservation, moisture retention, and weed suppression, significantly improving the quality of the crop growing environment. With the development of modern machinery, mulching and compaction machines have become increasingly functional. In some modern mulching and compaction machines, to prevent the film from blowing up in the middle after laying, some soil needs to be added to the middle area to achieve the compaction effect. Currently, most machines use a cylindrical drum for compaction, with soil added in the middle of the drum. The system creates a gap in the membrane, and the cylinder rotates with the mulching and compaction machine. During the mulching process, the covering wheel pushes some soil into the cylinder, which then diverts the soil. Some soil covers the edges of the membrane, while some enters the cylinder. As the cylinder rotates, the soil leaks out through the gap, forming intermittently distributed mounds that press the membrane down. However, in practice, the mounds are unevenly distributed on the membrane, and some areas are heavily pressed down, which can easily cover the plants and make the system inconvenient to use. Therefore, it is necessary to improve the diversion device to enhance the soil diversion effect and the uniformity of pressing down the membrane in the middle of the membrane. Utility Model Content
[0003] To overcome the technical defects of the existing technology, this utility model provides a soil diversion device for a mulching and compaction machine, which facilitates soil diversion and easy control of the amount of soil compacted on the middle position of the film, thereby improving the mulching effect.
[0004] The technical solution adopted by this utility model is: a soil diversion device for a mulched soil compactor, including a fixed cylinder. A fixed frame for fixed connection with an external mulched soil compactor is fixed to the upper end of the fixed cylinder. The fixed frame has a U-shaped structure, and a rotating shaft is rotatably installed between its two ends. A first roller and a second roller are respectively fixedly installed at the two ends of the rotating shaft. The ends of the first roller and the second roller opposite to each other are rotatably inserted into the fixed cylinder. A sleeve is obliquely fixedly installed on the fixed cylinder, and a helical rod is rotatably installed inside the sleeve. A soil discharge pipe is obliquely fixedly installed at one end of the sleeve, and a diversion plate is threadedly connected to the lower end of the soil discharge pipe on the fixed cylinder. The diversion plate has an inverted V-shaped structure. During use, the soil is diverted... The fixing frame is installed on the external film-covering and compacting machine, so that the lower ends of the first and second rollers contact the upper surface of the film after covering, which serves to hold and guide the film. During compaction, the external covering rollers lift the soil on both sides of the film, so that some soil compacts the edge of the film, and some soil enters the interior of the first and second rollers. Through the rotation of the first and second rollers, the soil moves towards the fixing cylinder, causing the spiral rod inside the sleeve to rotate, and the soil inside the fixing cylinder is rotated to the outlet pipe for discharge, falling into the middle of the upper surface of the covered film, which facilitates the distribution and compaction of the soil, forming soil covering on both sides and the middle of the film.
[0005] Preferably, both ends of the fixed frame are fixedly installed with rotating rings, and both ends of the rotating shaft are rotatably connected to the fixed frame through the rotating rings. Through the rotating rings, the first roller and the second roller can rotate on the rotating shaft when the external film-covering and soil compaction machine moves.
[0006] Preferably, retainers are fixedly installed at both ends of the rotating shaft, and the first roller and the second roller are respectively fixedly installed on the retainers at both ends, so as to facilitate the fixed installation of the first roller and the second roller on the rotating shaft.
[0007] Preferably, both ends of the fixing frame are fixedly installed with connecting ears, and the fixing frame is fixedly connected to the external film covering and compacting machine through the connecting ears, so as to facilitate the installation of the fixing frame on the external film covering and compacting machine.
[0008] Preferably, rubber scrapers are fixedly installed on both sides of the fixed cylinder on the fixing frame, and the scrapers at both ends are in contact with the outer surfaces of the first roller and the second roller, respectively. When the first roller and the second roller rotate, the scrapers scrape the soil off the surfaces of the first roller and the second roller to avoid damage to the film.
[0009] Preferably, both ends of the fixed cylinder are fixedly installed with insertion rings, and the first roller and the second roller are provided with insertion slots on opposite sides. The insertion rings are rotatably inserted into the insertion slots. The first roller and the second roller are fixedly installed with spiral blades, which facilitates the stable rotation of the first roller and the second roller on both sides of the fixed cylinder. The spiral blades also facilitate the transport of soil that has entered the first roller and the second roller into the fixed cylinder.
[0010] Preferably, a servo motor is fixedly installed at the end of the sleeve, and the output end of the servo motor is fixedly connected to the screw rod. One end of the screw rod located inside the fixed cylinder extends to the outside of the sleeve. The servo motor facilitates the driving of the screw rod, and the amount of soil discharged can be controlled by controlling the rotation speed of the servo motor.
[0011] Preferably, an internally threaded pipe is fixedly installed on the outside of the fixed cylinder, and a threaded rod is fixedly installed on one end of the diverter plate. The diverter plate is connected to the internally threaded pipe through the threaded rod, and the internally threaded pipe and the threaded rod facilitate the disassembly of the diverter plate.
[0012] The beneficial effects of this utility model are as follows: When in use, after the external covering wheel lifts the soil, part of it presses the soil against the edge of the film, and part of it enters the interior of the first and second rollers. It then enters the interior of the fixed cylinder through the spiral blades. The spiral rod causes the soil inside the fixed cylinder to be spiraled out and discharged into the middle position of the film through the soil outlet pipe, which improves the uniformity of soil pressing in the middle position of the film. In addition, the diversion plate facilitates the expansion of the soil pressing range, avoids the formation of soil piles, facilitates use, and makes it easy to divert the soil, thereby improving the film covering effect.

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] like Figures 1-5 As shown, this embodiment provides a soil diversion device for a mulching compactor, including a fixed cylinder 1. A fixed frame 2 for fixed connection with an external mulching compactor is fixed to the upper end of the fixed cylinder 1. The fixed frame 2 has a U-shaped structure, and a rotating shaft 3 is rotatably installed between its two ends. A first roller 4 and a second roller 5 are respectively fixed to the two ends of the rotating shaft 3. The opposite ends of the first roller 4 and the second roller 5 are rotatably inserted into the fixed cylinder 1. A sleeve 6 is obliquely fixedly installed on the fixed cylinder 1, and a spiral rod 7 is rotatably installed inside the sleeve 6. A soil discharge pipe 8 is obliquely fixedly installed at one end of the sleeve 6, and a diversion plate 9 is threadedly connected to the lower end of the soil discharge pipe 8 on the fixed cylinder 1. The diversion plate 9 has an inverted V-shaped structure. Whether to install the diversion plate 9 is selected according to the mulching requirements. When the diversion plate 9 is installed, two parallel compaction tracks are formed in the middle of the film surface. When the diversion plate 9 is not installed, one compaction track is formed in the middle of the film. During use, the fixed frame 2 is... Installed on an external film-covering compactor, the lower ends of the first roller 4 and the second roller 5 contact the upper surface of the film after covering, thus pressing and guiding the film. During use, the drive end of the external film-covering compactor drives the first roller 4 and the second roller 5 in contact, keeping them rotating at the same speed as the compactor. During compaction, the external covering rollers lift the soil on both sides of the film, causing some soil to compact the edges of the film while some soil enters the interior of the first roller 4 and the second roller 5. The rotation of the first roller 4 and the second roller 5 moves the soil towards the fixed cylinder 1, causing the spiral rod 7 inside the sleeve 6 to rotate, rotating the soil inside the fixed cylinder 1 to the outlet pipe 8 for discharge. The soil falls onto the middle of the covered film surface, facilitating soil distribution and compaction, covering the sides and middle of the film, and preventing the film from being blown or swayed by the wind, which could cause tearing.
[0021] As a technical optimization solution of this utility model, specifically as follows: Figure 1 and Figure 2As shown, both ends of the fixed frame 2 are fixedly installed with rotating rings 10. Both ends of the rotating shaft 3 are rotatably connected to the fixed frame 2 via the rotating rings 10. The rotating rings 10 facilitate the rotation of the first roller 4 and the second roller 5 on the rotating shaft 3 when the external mulching and compaction machine moves, thus transporting the soil. Both ends of the rotating shaft 3 are fixedly installed with retainers 11. The first roller 4 and the second roller 5 are respectively fixedly installed on the retainers 11 at both ends. The retainers 11 facilitate the fixed installation of the first roller 4 and the second roller 5 on the rotating shaft 3. Both ends of the fixed frame 2 are fixed... The fixing frame 2 is equipped with connecting ears 12, and is fixedly connected to the external film-covering and soil compaction machine through the connecting ears 12. The connecting ears 12 facilitate the installation of the fixing frame 2 on the external film-covering and soil compaction machine. Rubber scrapers 13 are fixedly installed on both sides of the fixing cylinder 1 on the fixing frame 2, and the scrapers 13 at both ends are in contact with the outer surfaces of the first roller 4 and the second roller 5 respectively. When the first roller 4 and the second roller 5 rotate, the scrapers 13 scrape the soil on the surfaces of the first roller 4 and the second roller 5 to improve cleanliness and avoid damage to the film.
[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 3 and Figure 4 As shown, both ends of the fixed cylinder 1 are fixedly installed with insertion rings 14. The first roller 4 and the second roller 5 are respectively provided with insertion slots 15 on opposite sides. The insertion rings 14 are rotatably inserted into the inside of the insertion slots 15. The first roller 4 and the second roller 5 are respectively fixedly installed with spiral blades 16. Through the insertion rings 14 and the insertion slots 15, the first roller 4 and the second roller 5 can rotate stably on both sides of the fixed cylinder 1.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3 and Figure 5 As shown, a servo motor 17 is fixedly installed at the end of the sleeve 6, and the output end of the servo motor 17 is fixedly connected to the screw rod 7. One end of the screw rod 7 located inside the fixed cylinder 1 extends to the outside of the sleeve 6. The servo motor 17 facilitates the driving of the screw rod 7, and by controlling the rotation speed of the servo motor 17, it is easy to control the amount of soil discharged, which facilitates the covering of the middle position of the film with soil. An internal threaded pipe 18 is fixedly installed on the outside of the fixed cylinder 1, and a threaded rod 19 is fixedly installed at one end of the diverter plate 9. The diverter plate 9 is connected to the internal threaded pipe 18 through the threaded rod 19. The internal threaded pipe 18 and the threaded rod 19 facilitate the disassembly of the diverter plate 9, making it convenient to select whether to install the diverter plate 9 and improving its applicability during use.
