Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire processing, in particular to a tire fixing mechanism for processing tires of rice transplanters. Background Art
[0002] Rice transplanter tires refer to wheel-type components used for rice transplanters, usually made of rubber and other materials, with specific structures and properties, and are used to provide support and movement capabilities for rice transplanters during operation.
[0003] Rice transplanter tires are usually processed through the following steps: first, select suitable rubber materials and cut them into blocks of appropriate sizes according to design requirements. Then, mix the rubber blocks with other additives, heat and stir them in a mixer to evenly mix the various materials. Then, push the mixed rubber into a mold, heat and press it to shape and solidify it to form the final tire product. Before the rice transplanter tires leave the factory, they also need to be trimmed and deburred. Trimming and deburring can make the edges of the tires smooth and flat, which helps the stability and service life of the tires during work, and improves the operating efficiency and safety of the rice transplanter.
[0004] When trimming and deburring a small batch of rice transplanter tires, workers are generally required to place the rice transplanter tires on an operating table for manual operation. However, it is not convenient for workers to perform processing on the rice transplanter tires placed on the operating table. The rice transplanter tires need to be turned over after processing on one side. The position far away from the workers also requires the workers to move the rice transplanter tires or go to the position to process them by themselves, which brings labor burden to the workers and affects the processing efficiency to a certain extent. To this end, we propose a tire fixing mechanism for rice transplanter tire processing. Utility Model Content

[0025] Working principle: First, the transplanter tire is sleeved on the middle part of the outer wall of the cylindrical barrel 2, then one hand holds the front edge of the cylindrical barrel 2 tightly, and the other hand rotates the handwheel 4, the handwheel 4 will drive the stud 12 to rotate inside the cylindrical barrel 2, and the stud 12 will drive the collar 13 to slide backward on the outer wall of the stud 12, and the three L-shaped plates 14 on the collar 13 will move backward in the rectangular grooves 8 on the corresponding cylindrical barrel 2, and the rear ends of the three L-shaped plates 14 will all move in the direction away from the center of the cylindrical barrel 2, and the three L-shaped plates 14 will also rotate on the corresponding connecting plates 5, the three connecting plates 5 will also rotate on the cylindrical blocks 17, and the rectangular shells 3 on the three connecting plates 5 will also move away from each other until the three rectangular shells 3 are tightly fitted with the inner wall of the transplanter tire, then the handwheel 4 can be stopped.

[0026] Subsequently, one of the rotating blocks 7 is rotated, and the rotating block 7 will drive the bidirectional screw rod 16 thereon to rotate in the corresponding rectangular shell 3, and the bidirectional screw rod 16 will drive the two limit blocks 11 to slide close to each other on the outer wall of the bidirectional screw rod 16, and the two limit blocks 11 will also slide close to each other in the rectangular groove 16 on the rectangular shell 3, until the two limit blocks 11 are tightly fitted with the outer wall of the rice transplanter tire, the rotating block 7 can be stopped, and the rice transplanter tire can be further fixed between the two limit blocks 11. Similarly, according to the same operation, the rice transplanter tire can be fixed between the other two groups of mutually corresponding limit blocks 11, and it can be applicable to the fixing of rice transplanter tires of different thicknesses. At this time, the staff can perform processing operations on the rice transplanter tire, and because the cylindrical barrel 2 rotates and is connected to the fixed frame 1, the staff can also rotate the rice transplanter tire according to processing needs.
[0027] It should be noted that the rice transplanter tire can be fixed and can be rotated according to processing needs.

This avoids the situation where the rice transplanter tire is far away from the staff and the staff need to move the rice transplanter tire or go to the location for processing by themselves. This brings convenience to the staff's processing operations, reduces the labor burden, and improves the processing efficiency to a certain extent.
