Threshing cylinder tooth component of whole-feed harvesting machine

Abstract

The invention provides a threshing cylinder tooth component of a whole-feed harvesting machine. The threshing cylinder tooth component comprises an installing base. The installing base is provided with cylinder teeth, the cylinder teeth are formed by forging of a 45# material, the cylinder teeth and anti-winding pieces inside the cylinder teeth are integrated, and no gap is formed between the anti-winding pieces and the cylinder teeth. The center of each cylinder tooth is in a cone shape, the protruded top ends are in an arc shape, and the two sides are of a symmetrical shape structure. Due to the fact that an integrated forging structure mode is adopted, the production cost is lower, the integral strength of the cylinder teeth is higher, and the anti-winding pieces and the external teeth are combined to be a whole to protect cylinder tooth gaps from weed winding; the top ends of the cylinder teeth are in an arc shape, the load is light during running, and the grain breakage rate is low; the two sides of the cylinder teeth are of the symmetrical shape structure, when one side is abraded, the other side can be turned and used, and the threshing cylinder tooth component is more economical and practical.

Description

technical field [0001] The invention relates to the field of a full-feed combine harvester, in particular to a tooth part of a threshing cylinder of a full-feed combine harvester. Background technique [0002] The detachment chamber of the combine harvester is mainly composed of a drum, a top cover, a cutter, a filter screen, a vibrating screen, a blower, and a conveying auger. When harvesting, the rice straw is transported to the threshing chamber by the conveyor belt and passed through the teeth of the drum. Drive the rotation of the rice stalk and the blocking impact of the filter screen to achieve the effect of separating the rice stalk from the grain and crushing the rice stalk. Due to the large friction force, the drum tooth parts are vulnerable. At present, the drum teeth of the semi-feed thresher are mainly bow teeth Mainly, this type of roller tooth A is bow-shaped and formed by bending steel bars, and is fixed on the bottom plate C. There is an anti-winding piece B...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the defects of high maintenance cost, grass entanglement and easy damage of the existing full-feed harvester drum teeth, the present invention provides a full-feed combine harvester threshing drum tooth part, which has sufficient strength and hardness, reasonable structure, and can Meet the threshing and crushing requirements of the full-feed harvester during high-speed cutting, effectively reduce the grain breakage rate, and at the same time make the maintenance of the drum teeth more low-cost, simpler and safer
