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 crushing tooth 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 by the material to the scraper below. On the scraper conveyor, the friction between the related components of the scraper conveyor increases, which in turn accelerates the wear of its related parts, and even causes accidents such as scraper jamming, which seriously affects the overall operation stability and continuous operation of the feeder crusher. sex

Abstract

The invention discloses a crushing cutter tooth used for a crushing tooth assembly. The crushing cutter tooth comprises a tooth body; the front end of the upper surface of the tooth body is provided with a front cutter face; the front end of the front cutter face is provided with a cutter; the front end surface of the tooth body is provided with a main rear cutter face; the included angle between the main rear cutter face and the front cutter face is an acute angle. In the working process, the included angle between the main rear cutter face and the front cutter face is the acute angle, the extrusion force to the material caused by the crushing cutter tooth, 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 crushing cutter tooth is simpler and more reliable in a whole assembly structure. The invention also discloses the crushing tooth assembly adopting the crushing cutter tooth.

Description

technical field [0001] The invention relates to the technical field of feeding crushers, in particular to a crushing knife tooth. The invention also relates to a crushing tooth assembly using the crushing blade. 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 crushing tooth 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 b...
