[0002] A weeding roller (sprocket roller weeder) is an agricultural machine used to remove weeds during crop growth. This equipment usually consists of a series of sprockets equipped with sharp teeth or roller teeth that crush or cut weeds by rotating. The design and adjustment capabilities of the weeding roller are crucial to improving weeding efficiency and reducing damage to crops.

[0003] After searching, the weeding tooth disc spacing quick adjustment structure of the weeding tooth disc roller of the announcement number CN220191479U is a structure in which the weeding tooth disc is positioned circumferentially and radially and axially movably mounted on the square roller shaft of the weeding tooth disc roller in sequence, and threaded holes are respectively opened along the axial direction at the symmetrical parts of the weeding tooth disc hub, and the separated optical axis fixing ring is respectively snap-fitted and installed at the parts between adjacent weeding tooth discs on the square roller shaft of the weeding tooth disc roller, and long strip through holes are respectively arranged on the upper and lower half rings of the separated optical axis fixing ring along the axial direction, and the assembly screws pass through the long strip through holes on the upper and lower half rings and are screwed into the threaded holes on the weeding tooth disc to fix the separated optical axis fixing ring and the weeding tooth disc at the same side into one body, and the countersunk fastening screw locks the separated optical axis fixing ring and the weeding tooth disc as a whole on the square roller shaft of the weeding tooth disc roller through the clamping cooperation of the upper and lower half rings; the adjustment operation of this structure is simple and convenient, the adjustment accuracy is high, and the adaptability is strong;

[0004] Based on the above patent, the existing weeding toothed disc rollers mentioned in the background technology are all equipped with multiple weeding toothed discs on the square roller shaft in sequence, and then clamped by the fastening nuts installed on the two ends of the square roller shaft, the multiple weeding toothed discs installed on the square roller shaft are axially locked and positioned to complete the assembly of the weeding toothed disc roller. The spacing between adjacent weeding toothed discs on the weeding toothed disc roller of this structure is all achieved and solved by the way of matching different lengths or different numbers of integral spacing sleeves. When the spacing between adjacent weeding toothed discs needs to be adjusted, the fastening nut on one end of the square roller shaft should be loosened and removed, and then the weeding toothed discs and the integral spacing sleeve should be removed from the square roller shaft in sequence, and then the integral spacing sleeves and weeding toothed discs of different lengths or different numbers should be installed in sequence according to the requirements of the adjacent toothed disc spacing after adjustment. The labor intensity is high, the operation efficiency is low, the operation is cumbersome, the adjustment accuracy is poor, and the number of spare parts of the integral spacing sleeve is large. In view of this technical problem, the present application proposes a weeding toothed disc roller with adjustable toothed disc spacing. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 The utility model provides an embodiment: a weeding toothed disc roller with adjustable toothed disc spacing, including a roller shaft 1, a connecting column 2 is fixedly connected to the left and right ends of the roller shaft 1, a rotating rod 3 is rotatably connected to the inner wall of the top end of the right connecting column 2, a knob 4 is fixedly connected to the top of the rotating rod 3, an active bevel gear 5 is fixedly connected to the bottom end of the rotating rod 3, and a driven bevel gear 6 is fixedly connected to the outer wall of the right end of the bidirectional threaded rod 7, the active bevel gear 5 is meshed with the driven bevel gear 6, and the inner wall of the connecting block 8 is respectively threadedly connected to the left and right ends of the bidirectional threaded rod 7. On the outer walls at both right ends, the outer wall of the right end of the bidirectional threaded rod 7 is rotatably connected to the inner wall of the connecting column 2, and the left end of the bidirectional threaded rod 7 is rotatably connected to the inner wall of the left end of the roller shaft 1. The inner walls at the upper and lower ends of the roller shaft 1 are slidably connected with multiple slides 9, and the middle of the rear ends of the slides 9 on both sides are fixedly connected to the front end of the connecting block 8. The upper and lower ends of the slides 9 are fixedly connected to the toothed disc body 10, and the middle of the front end of the slides 9 is fixedly connected to the connecting rod 11. The outer wall of the front end of the connecting rod 11 is rotatably connected to the connecting plate 12, and the connecting plates 12 are relatively connected by rotation.

[0023] Specifically, when the distance between the toothed disc bodies 10 is to be adjusted, the knob 4 is turned to drive the rotating rod 3 to rotate, and then the active bevel gear 5 is driven to rotate. The rotation of the active bevel gear 5 drives the driven bevel gear 6 to rotate, and then the bidirectional threaded rod 7 is driven to rotate. The rotation of the bidirectional threaded rod 7 drives the connecting blocks 8 on both sides to move inward at the same time, and then the slides 9 on both sides are driven to move inward. The slides 9 on both sides move inward at the same time, thereby driving the connecting plates 12 on the left and right sides to move inward at the same time, thereby reducing the angle between the connected connecting plates 12, and reducing the distance between the middle parts of adjacent connecting plates 12. The middle parts of the connecting plates 12 are connected to the slides 9 on the connecting rods 11, so that the distance between the adjacent slides 9 is reduced, which can reduce the distance between the toothed disc bodies 10. Similarly, rotating the knob 4 in the opposite direction can increase the distance between the toothed disc bodies 10.

[0024] Working principle: First, when the distance between the toothed disc bodies 10 is to be adjusted, the knob 4 is turned to drive the rotating rod 3 to rotate, and then the active bevel gear 5 is driven to rotate. The active bevel gear 5 is rotated to drive the driven bevel gear 6 to rotate, and then the two-way threaded rod 7 is driven to rotate. The rotation of the two-way threaded rod 7 drives the connecting blocks 8 on both sides to move inward at the same time, and then the slides 9 on both sides are driven to move inward. The slides 9 on both sides move inward at the same time, thereby driving the connecting plates 12 on the left and right sides to move inward at the same time, thereby reducing the angle between the connected connecting plates 12, and reducing the distance between the middle parts of adjacent connecting plates 12. The middle parts of the connecting plates 12 are connected to the slides 9 on the connecting rod 11, so that the distance between the adjacent slides 9 is reduced, which can reduce the distance between the toothed disc bodies 10. Similarly, rotating the knob 4 in the opposite direction can increase the distance between the toothed disc bodies 10.
