The inside of the two conveyor belt box slot plates 7 is fixedly connected with the conveyor belt bearings 10. The outside of the conveyor belt bearings 10 is fixedly connected with the conveyor belt driven gear shaft 9. The outside of the conveyor belt driving gear shaft 4 is sleeved with a transmission assembly. The outside of the transmission assembly is fixedly connected with multiple conveyor belt chain rake plates 6. It is designed here that the displacement of the conveyor belt chain rake plates 6 can realize the lifting and transportation of materials. The far side of the conveyor belt box slot plate 7 is slidably connected with a conveyor belt tensioning push-pull plate 11. It is designed here that the tightness of the conveyor belt can be adjusted by the conveyor belt tensioning push-pull plate 11.

[0020] Reference Figure 2 - Figure 4The transmission assembly includes two conveyor belt drive chains 5, the outsides of the two conveyor belt drive chains 5 are meshed and connected to the outside of the conveyor belt drive gear shaft 4, and the outside of the conveyor belt drive chain 5 is fixedly connected with multiple conveyor belt driven gear shafts 9. It is designed here that a conveyor belt drive chain 5 is sleeved on the outside of a conveyor belt drive gear shaft 4 and a corresponding conveyor belt driven gear shaft 9, and then the conveyor belt drive chain 5 can be driven to rotate with the rotation of the conveyor belt drive gear shaft 4, and then the lifting and transportation of materials can be achieved through the cooperation of the conveyor belt chain rake plate 6. The outside of the conveyor belt drive gear shaft 4 is rotatably connected to the inside of the conveyor belt chain rake supporting plate 8, and the conveyor belt drive gear shaft 4 and the conveyor belt drive chain 5 are meshed.

[0021] Working principle: When it is necessary to harvest crops, the conveyor belt hydraulic drive motor 1 is used to drive the conveyor belt drive shaft coupling 2 to rotate, and then the conveyor belt drive gear shaft 4 can be driven to rotate. At this time, the conveyor belt drive gear shaft 4 and the conveyor belt drive chain 5 are meshed and connected to each other, so that the conveyor belt drive chain 5 is displaced. As the conveyor belt drive chain 5 is displaced, the conveyor belt chain rake plate 6 is displaced, and then the conveyor belt driven gear shaft 9 and the bearing transition disk are combined to realize directional transmission. At this time, the material is lifted to the destination through the displacement of the conveyor belt chain rake plate 6. The tightness of the conveyor belt is adjusted by the push-pull combination of the threaded pair of the conveyor belt tensioning push-pull plate 11. The bearing makes the equipment run smoothly and reduces the failure point. The design here cancels the drive sprocket and the sprocket tensioning mechanism and changes to hydraulic motor drive, so that the drive shaft is more efficient, stable and safer, thereby improving the working efficiency of the harvester conveyor belt and reducing the failure rate.
