Feed crusher, crushing tooth roller and its crushing tooth assembly

Abstract

The invention discloses a crushing tooth assembly. A crushing cutter tooth is inserted in a cutter tooth installing hole in the middle of the front end face of a tooth holder, the lower bottom surface of the tooth holder is an arc surface, the lower bottom surface of the tooth holder is tangent to a material conveying direction, a front cutter surface is arranged at the front end part of the upper surface of the crushing cutter tooth, a cutter is arranged at the front end of the front cutter surface, a main rear cutter surface is arranged on the front end face of the crushing cutter tooth, and an included angle between the main rear cutter surface and the front cutter surface is an acute angle. In a working process, because the lower bottom surface of the tooth holder is the arc surface tangent to the material conveying direction and the included angle between the main rear cutter surface and the front cutter surface is the acute angle, an extruding force of relevant parts of the crushing tooth assembly to materials in a running process of the crushing tooth assembly can be effectively reduced or avoided, and further the abrasion of a scraper conveyer below the crushing tooth assembly and among the relevant parts is prevented; and an integral assembling structure of the crushing tooth assembly is simple and reliable. The invention also discloses a crushing tooth roller adopting the crushing tooth assembly and a fed material crusher adopting the crushing tooth roller.

Description

technical field

[0001] The invention relates to the technical field of feed crushers, in particular to a crushing tooth assembly and a crushing tooth roller using the crushing tooth assembly. The invention also relates to a feed crusher using the crushing gear roller. 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 It is complex, and its assembly volume is large. During the operation of the equipment, it is very easy to squeeze the material below the crushing tooth assembly. The force formed during...
