Crushing tooth assembly and tooth holder thereof

Abstract

The invention discloses a tooth holder used for a crushing tooth assembly. The tooth holder comprises a body; a cutter tooth mounting hole matched with a crushing cutter tooth is formed in the middle of the front end surface of the body; the lower bottom surface of the body is a circular arc surface; the lower bottom surface of the body is tangent with the conveying direction of the material. In the working process, the lower bottom surface of the body is the circular arc surface which is tangent with the conveying direction of the material, the extrusion force to material caused by the tooth holder, the crushing tooth assembly and related parts can be effectively reduced or avoided in the running process of equipment, and the abrasion between a scraper conveyor arranged at the lower part and related parts can be further avoided; furthermore, the tooth holder is simpler and more reliable in a whole assembly structure. The invention also discloses the crushing tooth assembly adopting the tooth holder.

Description

technical field [0001] The invention relates to the technical field of feed crushers, in particular to a gear seat. The invention also relates to a crushing tooth assembly using the tooth seat. Background technique [0002] Feed crusher is a kind of construction machinery equipment used for material conveying and transfer, and the crushing tooth assembly is the main material processing device of feed crusher, and its working performance is also widely concerned by people. [0003] At present, during the working process of the existing crushing tooth assembly, the materials to be processed or crushed will be conveyed through the scraper conveyor located under the crushing tooth assembly. However, due to the relatively Complex, especially the large assembly volume of the tooth seat part, it is very easy to squeeze the material under the crushing tooth assembly during the operation of the equipment, and the force formed during the extrusion process will be transmitted to the l...

Problems solved by technology

[0003] At present, during the working process of the existing crushing tooth assembly, the materials to be processed or crushed will be conveyed through the scraper conveyor located under the crushing tooth assembly. However, due to the relatively Complex, especially the large assembly volume of the tooth seat part, it is very easy to squeeze the material under the crushing tooth assembly during the operation of the equipment, and the force formed during the extrusion process will be transmitted to the lower scraper by the material On the conveyor, the friction between the relevant components of the scraper conveyor increases, which in turn accelerates the wear of its related components, and even causes accidents such as scraper jamming, which seriously affects the overall operation stability and continuity of the feed crusher.
