Plugging gear crusher tooth roller with interlocking mechanism and compression-shear blades

Abstract

A plugging gear crusher tooth roller with an interlocking mechanism and compression-shear blades comprises multiple hollow roller bodies, external circular surfaces of which are respectively provided with multiple rows of tooth handle holes. Multiple roller teeth are respectively inserted in the multiple rows of tooth handle holes. The multiple roller teeth comprise a protective bench and a tooth handle respectively. Multiple tooth columns and multiple compression-shear blades which are integrally connected and arranged at intervals are arranged along the peripheral direction of the hollow roller body on the upper surface of the protective bench. Corresponding sides of the protective benches of each two adjacent roller teeth have an interlocking mechanism respectively. According to the invention, material consumption is greatly reduced, and a processing technology is simplified. A high-hardness material and a high-toughness material are organically combined, thus making the best use of things, decreasing dosage of noble metal, reducing abrasion and greatly improving crush efficiency and grinding fineness and uniformity of a product. by the design of the interlocking mechanism and the roller teeth correspondingly inserted in the tooth handle holes in the roller bodies through the tooth handles, equipment is simple to install and convenient to adjust and maintain.

Description

technical field [0001] The present invention mainly relates to a crusher for crushing mineral products, in particular to a toothed roller crusher, in particular to a plug-and-pull toothed crusher toothed roller with an interlocking mechanism and a pressing shear blade. Background technique [0002] With the rapid development of my country's economy, the scale of infrastructure construction is huge. The demand for building materials will be staggering. China is also a country with a large demand for mineral products. The mineral product processing market has broad prospects. At present, in China and even abroad, the crushing and processing equipment of mineral products has been hovering in the "one low" and "three high" of low efficiency, high energy consumption, high wear and high pollution. For example, "hammer crusher", "impact crusher" and "cone crusher" have always been equipped with high power, large machine wear, low efficiency, high noise, and serious dust poll...

AI Technical Summary

Problems solved by technology

The patent number is ZL201020625553.9 for the toothed roller crusher patent. Although the fundamental problem of the crusher is solved, the manufacturing process is relatively complicated and the cost is high

[0003] There is no cutting edge on the teeth of the existing crusher toothed rollers, so the crushing rate is relatively low, and the roller body of the crusher toothed rollers is a solid structure, which is expensive; in addition, the roller teeth of the crusher toothed rollers are made of single metal , consumes a lot of precious metals, and the cost is high. The roller teeth are directly and independently inserted into the mounting holes on the surface of the roller body during installation, which is cumbersome to fix and time-consuming to disassemble.
