Technical Field

[0001] This utility model relates to the field of potato planting technology, specifically a device for trenching and hilling potato planting. Background Technology

[0002] In the process of potato planting, ditching and ridging machines are needed. Ditching and ridging machines are commonly used equipment in the field of agricultural machinery. They are mainly used for inter-row cultivation and ridging operations in the planting of crops such as sugarcane. The machine adopts the principle of plowing and rotating, and guides the soil to flow to the roots of the crop through guide plates, realizing the mechanized operation of soil transportation and redistribution.

[0003] However, the shafts and plow blades of existing trenching and ridging machines are fixed together with bolts and nuts. Since the plow blades rotate at high speed during operation, there is a possibility that the bolts and nuts may loosen, potentially causing the plow blades to fly out and injure the user. Therefore, existing trenching and ridging machines have certain safety defects. To address these issues, innovative designs based on existing trenching and ridging machines are urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a potato planting trenching and hilling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a potato planting trenching and ridging device, comprising a trenching and ridging machine body, wherein a rotating shaft is internally mounted on the trenching and ridging machine body, and rectangular blocks are fixed at both ends of the rotating shaft. A ring sleeve and a rectangular sleeve are nested on the outer side of each rectangular block, and the ring sleeve and rectangular sleeve are integrally formed. A plow blade is fixed to the outer wall of the ring sleeve. Bolts penetrate the interior of both the rectangular blocks and rectangular sleeves, and nuts are threaded onto the lower end of each bolt. A slot is formed on the outer side of each bolt. A fixing plate is fixed to the outer wall of the rectangular sleeve. A rotating plate is mounted on the bottom of the fixing plate via a rotating mechanism. A movable rod penetrates the interior of the rotating plate. A clamp is fixed to one end of the movable rod, and the top of the clamp abuts against the bottom of the nut. The clamp engages within the slot. A pressure plate is fixed to the outer wall of the movable rod, and a spring is nested on the outer side of the movable rod. The spring is located between the rotating plate and the pressure plate.

[0006] Preferably, the rotating mechanism includes a rotating rod, the rotating rod is fixed to the top of the rotating plate, the rotating rod is configured as a "T" shaped structure, and the outer side of the lower half of the rotating rod is in contact with the inner side of the fixed plate.

[0007] Preferably, the end of the movable rod is configured as a rectangular structure, and the outer side of the movable rod is in contact with the inner side of the rotating plate.

[0008] Preferably, a pull rod is fixed to the end of the movable rod away from the clamp, and the end of the movable rod and the pull rod are combined to form a "T" shaped structure.

[0009] Preferably, a bellows is fixed to one side of the pressure plate and one side of the rotating plate, and the spring is located inside the bellows.

[0010] Preferably, the card is configured as a "U" shaped structure, with the inner side, top and bottom of the card fitting against the inner side of the card slot, and the end of the card penetrating the interior of the card slot.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: a potato planting trenching and ridging device, including a trenching and ridging machine body 1. A rotating shaft 2 is rotatably mounted inside the trenching and ridging machine body 1 via a sealed bearing. Rectangular blocks 3 are fixed at both ends of the rotating shaft 2 outside the trenching and ridging machine body 1. Annular sleeves 4 and rectangular sleeves 6 are movably nested on the outer sides of the rectangular blocks 3, and the annular sleeves 4 and rectangular sleeves 6 are integrally formed. A plow blade 5 is fixed to the outer wall of the annular sleeve 4. Bolts 7 movably penetrate the interiors of both the rectangular blocks 3 and the rectangular sleeves 6, with threads at the lower end of the bolts 7. Nut 8 is installed. A slot 13 is opened on the outside of bolt 7. A fixing plate 9 is fixed on the outer wall of rectangular sleeve 6. A rotating plate 10 is installed at the bottom of fixing plate 9 through a rotating mechanism. A movable rod 11 is movably passed through the inside of rotating plate 10. A clamp 12 is fixed at one end of movable rod 11. The top of clamp 12 abuts against the bottom of nut 8. Clamp 12 is engaged in the inside of slot 13. A pressure plate 14 is fixed on the outer wall of movable rod 11. A spring 15 is movably nested on the outside of movable rod 11. Spring 15 is located between rotating plate 10 and pressure plate 14.

[0018] The rotating mechanism in this example includes a rotating rod 16. The rotating rod 16 is fixed to the top of the rotating plate 10. The rotating rod 16 is configured as a "T" shaped structure. The outer side of the lower half of the rotating rod 16 is in contact with the inner side of the fixed plate 9, and the bottom of the upper half of the rotating rod 16 is in contact with the top of the fixed plate 9. The top of the rotating plate 10 is in contact with the bottom of the fixed plate 9. This ensures that after the movable rod 11 drives the locking piece 12 to separate from the locking slot 13, the movable rod 11 and the locking piece 12 can be rotated through the rotating plate 10 and the rotating rod 16, so that the locking piece 12 can be separated from the locking slot 13. This ensures that the locking piece 12 will not hinder the rotation and disassembly of the nut 8.

[0019] In this example, the end of the movable rod 11 is set as a rectangular structure. The outer side of the movable rod 11 fits against the inner side of the rotating plate 10, ensuring that the movable rod 11 can only move in a straight line on the rotating plate 10, and there will be no rotation of the movable rod 11 and the locking piece 12, which is beneficial for the locking piece 12 to be installed on the locking slot 13.

[0020] In this example, a pull rod 18 is fixed at the end of the movable rod 11 away from the clamp 12. The end of the movable rod 11 and the pull rod 18 are combined to form a "T"-shaped structure, which allows the movable rod 11 and the clamp 12 to be moved manually by the pull rod 18.

[0021] In this example, a bellows 17 is fixed to one side of the pressure plate 14 and one side of the rotating plate 10. The spring 15 is located inside the bellows 17. The bellows 17 is designed to prevent soil from entering the spring 15, so that the spring 15 can be used normally.

[0022] In this example, the card 12 is designed with a "U" shape. The inner side, top and bottom of the card 12 are respectively attached to the inner side of the card slot 13. The end of the card 12 penetrates the interior of the card slot 13, which extends the length of separation between the card 12 and the card slot 13 and prevents the card 12 from separating from the card slot 13 automatically.

[0023] In this example, the inner sides of the annular sleeve 4 and the rectangular sleeve 6 fit snugly against the outer side of the rectangular block 3, so that the annular sleeve 4 and the rectangular sleeve 6 will not wobble after being installed on the rectangular block 3.

[0024] In this example, a sprocket 19 is nested and fixed in the middle of the shaft 2. The output end of the diesel engine on the trenching and ridging machine body 1 is rotatably connected to the sprocket 19 on the shaft 2 through another sprocket 19 and a chain.

[0025] Working principle: When using this potato planting trenching and hilling device, to remove the plow blade 5, pull the lever 18 by hand. The lever 18 drives the movable rod 11, the locking piece 12, and the pressure plate 14 to move simultaneously. The pressure plate 14, in conjunction with the rotating plate 10, further compresses the spring 15. (See attached...) Figure 5 The spring 15 is in a compressed state. Through actual testing, when the rotating shaft 2 drives the plow blade 5 to rotate, the locking piece 12 is always engaged with the slot 13 under the elastic force of the spring 15 (preventing the locking piece 12 from separating from the slot 13). When the locking piece 12 separates from the bolt 7, the rotating plate 10, the movable rod 11 and the locking piece 12 are rotated by the rotating rod 16 to ensure that the locking piece 12 will not re-engage with the slot 13 when the pull rod 18 is released. This ensures that the locking piece 12 will not hinder the disassembly of the bolt 7 and the nut 8. The nut 8 is rotated with a wrench to remove the nut 8 and the bolt 7 from the rectangular block 3 and the rectangular sleeve 6. Finally, the ring sleeve 4, the plow blade 5 and the rectangular sleeve 6 are removed from the rectangular block 3. Reinstall the annular sleeve 4, plow blade 5, and rectangular sleeve 6 back onto the rectangular block 3. Then, pass the bolt 7 through the inside of the rectangular block 3 and the rectangular sleeve 6. Next, install the nut 8 at the lower end of the bolt 7. Then, pull the pull rod 18. The pull rod 18 drives the movable rod 11, the clamp 12, and the pressure plate 14 to move simultaneously. The pressure plate 14 cooperates with the rotating plate 10 to further compress the spring 15. Rotate the rotating plate 10, movable rod 11, and clamp 12 through the rotating rod 16 until the clamp 12 is aligned with the slot 13. Slowly reduce the pulling force on the pull rod 18. Under the elastic force of the spring 15, the clamp 12 engages with the slot 13. At this time, the top of the clamp 12 abuts against the bottom of the nut 8. Therefore, under the limit of the clamp 12, there will be no loosening between the bolt 7 and the nut 8, thereby preventing the plow blade 5 from flying off the rotating shaft 2. This protects the user and improves the safety of the trenching and ridging machine body 1. By starting the diesel engine on the main body 1 of the trenching and ridging machine, the diesel engine drives the two plow blades 5 to rotate simultaneously through two sprockets 19, chains and shafts 2, thus making the soil trenched and ridged.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
