Abstract

The invention discloses a roller type rock breaking device for a blind area of a heading machine. The technical problem that an existing large-section heading machine cannot conduct efficient breaking and deslagging on a hard rock blind area is solved. The device comprises a roller, a driven roller is arranged on the rear side of the roller, the roller and the driven roller are in transmission connection through a crawler belt, and a plurality of cutting tooth assemblies are arranged on the crawler belt. During construction, the roller drives the crawler belt to rotate, the cutting tooth assemblies formed on the crawler belt rotate and extrude the blind area to crush rocks in the blind area within the distance between the cutting teeth, then the cutting tooth assemblies drive the crushed rocks to the rear portion of the roller for deslagging, and the device can be used for excavating the blind area formed after tunneling of a horseshoe-shaped tunneling machine and other large-section tunneling machines. The cutting tooth assembly is small in working resistance, flexible in rotation performance, resistant to abrasion and not prone to falling off, sparks are not prone to being generated during operation, hard rocks can be effectively cut, and the drum-type structure can drive rock residues to be discharged outwards in the process of driving the cutting tooth assembly to break rocks.

Description

technical field [0001] The invention relates to the technical field of the tunneling mechanism of a roadheader, in particular to a roller type rock breaking device in the blind area of ​​the roadheader. Background technique [0002] Large-section roadheaders have blind spots due to their structural characteristics, such as figure 1 The shown horseshoe roadheader has many blind spots 1 and different positions. When excavating soft soil or soft rock tunnels, the blind area is squeezed and broken by the thrust of the roadheader, but the strength of the hard rock is high, and the thrust of the roadheader cannot effectively solve the blind area of ​​the hard rock. Therefore, it is necessary to study a rock-breaking device that can solve the blind area of ​​large-section driving, so that the large-section roadheader can work normally in hard rock environment. [0003] The invention patent with the application publication date of 2013.02.13 and the application publication number ...
