Problems solved by technology

[0002] Excavation equipment often encounters hard rock during mining and tunneling operations. The working devices of existing equipment generally adopt mechanical rock crushing, which greatly affects the excavation due to severe tool wear and frequent tool change operations. Work efficiency, not widely used in hard rock crushing
Therefore, there is an urgent need to carry out research on new methods of hard rock crushing and develop a new type of hard rock crushing device to solve the problem of rapid tool wear during mining.

Abstract

The invention discloses a disc crusher. Rotational motion is transferred to a disc crushing device by an external driving rotary input shaft through a rotary connecting shaft, a rotary connecting hub, a rotary connecting sleeve and a supporting frame to change the direction of the disc crushing device, so that disc cutters on the disc crushing device are aligned to rock in different directions. A power output device in the crushing supporting device transfers power to the disc crushing device, and the rock is crushed through the disc cutters on the disc type crushing device. According to the disc crusher, all the disc cutters form a meshy track in the space through two kinds of rotational motion and crush the rock, and the rocks at different angles are crushed. A supporting dis rotates to drive the disc cutters on the supporting disc to extrude, cut and crush the rock, and hard contact between the disc cutters and the rock is reduced. Meanwhile, the rotary input shaft is utilized for driving the disc crushing device integrally connected with the rotary connecting sleeve to rotate, and therefore the disc cutters form the meshy track in the space and crush the rock, and crushing and mining of the rock are accelerated.

Description

technical field [0001] The invention relates to the field of hard rock crushing, in particular to a disc crusher. Background technique [0002] Excavation equipment often encounters hard rock during mining and tunneling operations. The working devices of existing equipment generally adopt mechanical rock crushing, which greatly affects the excavation due to severe tool wear and frequent tool change operations. Work efficiency is not widely used in hard rock crushing. Therefore, there is an urgent need to carry out research on new methods of hard rock crushing and develop a new type of hard rock crushing device to solve the problem of rapid tool wear during mining. Contents of the invention [0003] The object of the present invention is to provide a disc crusher to overcome the deficiencies of the prior art. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A disc crusher comprising a rotary input device, a ro...
