Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] The overall structure of the present invention is as figure 1 As shown, it includes a feed hopper 1, an upper box body 2, a toothed roller 3, a power unit 4, a main shaft 5, a lower box body 6, an end cover 7, a discharge hopper 8, a base 9, an air inlet pipe 10, and a transmission device 11; The hopper 1 is set at the entrance of the upper box body 2. The two are connected and fixed by bolt holes on the side. The lower box body 6 is located directly below the upper box body 2, and the upper box body 2 and the lower box body 6 are opened through the front and rear sides of the box body The connecting hole is bolted. The gear roller 3 is divided into a left gear roller 3-1 and a right gear roller 3-2. The right gear roller 3-2 is connected to the main shaft 5. One side of the main shaft 5 is equipped with a power unit 4, and the other side It is connecte...

Abstract

The invention provides a double-toothed roller crusher and a working method thereof. The double-toothed roller crusher improves a roller tooth structure of a toothed roller machine; a roller surface of each toothed roller is provided with 10-20 laps of roller teeth in a direction parallel to the axis; gaps among all laps of roller teeth are equal; each toothed roller is provided with multiple rows of roller teeth in the radial direction; included angles between every two adjacent teeth are equal; the roller teeth of each toothed roller consist of high teeth and low teeth; and one row of high teeth is arranged by every four rows of low teeth. The lower surface of a lower box body is of a through hole structure; 3-4 cleaning holes are respectively formed in the left and right side surfaces of the lower box body; and intake pipes with corresponding numbers are mounted in the cleaning holes. The double-toothed roller crusher improves the roller tooth structure of the toothed roller machine, solves the problem of influence on the crushing efficiency by incapability of effectively crushing one part of materials with regular shapes, can improve the defect of weak cleaning capacity of the toothed roller machine, and is excellent in self-cleaning capacity.

Description

Technical field [0001] The invention relates to the field of coal crushing devices, in particular to a double-tooth roller crusher and a working method thereof. Background technique [0002] In the coal sample preparation system, the coal must be crushed to a certain particle size before it can be sampled. Roller crushers are widely used because of their continuous work, high crushing efficiency and uniform product size. However, the traditional roller crusher with equal-height roller teeth may cause some materials with regular shapes to roll over the roller and cannot be effectively crushed, and it needs to be shut down during cleaning, which is time-consuming, labor-intensive and inefficient. Therefore, the development of a new type of toothed roller crusher is an urgent problem to be solved. Summary of the invention [0003] In order to solve the problems of the prior art, the present invention provides a double-toothed roller crusher and a working method thereof, improves th...
