Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wheat harvesters, in particular to an end-side fixing device for a double-layer vibrating screen in a wheat harvester. Background Technique
[0002] A wheat harvester relies on a gasoline engine as power, drives a saw blade to rotate at a high speed through a transmission shaft, thereby playing a role in harvesting. There are various types of harvesters, including models with a single-layer vibrating screen and models with a double-layer vibrating screen. Among them, the model with a double-layer vibrating screen has a better effect of screening and removing wheat bran compared to the single-layer vibrating screen.
[0003] The upper vibrating screen and the vibrating bin frame are connected through a connecting piece. The connecting piece mainly includes two upper and lower connecting shafts and a connecting seat connected between the two upper and lower connecting shafts. The two upper and lower connecting shafts are respectively fixed on the side walls of the upper vibrating screen and the vibrating bin frame, and rubbers are fixedly sleeved on the two upper and lower connecting shafts. Then, the connecting seat wraps the rubber and is fixed on the connecting shaft.
[0004] Regarding the above-mentioned related technology, the inventor believes that under the high-intensity vibration of the vibrating screen, the rubber is easily worn into debris and falls off, so that the elastic buffer protection between the connecting shaft and the connecting seat is lost. In this case, if the vibrating screen continues to be used, it will directly cause damage or even breakage and falling off of the side wall of the vibrating screen. Content of the Utility Model
