Coal mine tunneling device capable of being adjusted in multiple directions

Abstract

The invention discloses a coal mine tunneling device capable of being adjusted in multiple directions. The coal mine tunneling device comprises a machine body, wherein a slewing bearing is arranged onthe outer wall of the top of the machine body; a slewing motor is arranged in the slewing bearing; an adjusting plate is fixedly connected to the outer wall of the top of the slewing bearing; adjusting grooves which are symmetrically distributed are formed in the outer wall of the top of the adjusting plate; rod grooves are formed in the two sides of the inner wall of each adjusting groove; a bearing rod is rotationally connected to the inner wall of each rod groove; the outer wall of each bearing rod is sleeved with an adjusting wheel; a clamping groove is formed in the position, located inthe middle of the corresponding adjusting groove, of the outer wall of a top plate of the adjusting plate; and a limiting plate is fixedly connected to the inner wall of each clamping groove. According to the coal mine tunneling device, the stability of the device during tunneling operation can be guaranteed while multi-directional adjustment is achieved, a supporting rod, a tunneling control boxand the limiting plates form a stable triangular structure so as to counteract the counter-acting force during tunneling, a dust blocking cover and an air suction cover serve as a first suction fan protection mode, and the bowl-shaped air suction cover is buckled on the dust blocking cover, so that solid particles are not prone to being sucked into the device.

Description

technical field [0001] The invention relates to the technical field of coal mine tunneling devices, in particular to a coal mine tunneling device that can be adjusted in multiple directions. Background technique [0002] Excavation is the work of excavating wells, lanes, and chambers of various shapes, sections, or criss-crossing in rock formations or mine layers. The existing coal mine excavation equipment adjusts its orientation through the overall movement of the body. When there are many coal mine debris on the ground, When it is inconvenient to move, adjusting the position becomes a problem. [0003] After searching, the Chinese patent authorization number is CN108086974A, which discloses a coal mine tunneling device that can be adjusted in multiple directions, including a base, a movable plate, a first transmission chamber, a second transmission chamber and a tunneling mechanism; the lower end of the base is symmetrically installed There are outriggers; the upper end ...

AI Technical Summary

Problems solved by technology

The coal mine excavation device in the above-mentioned patent has the following disadvantages: the overall structure of the device is unstable, and it uses the first threaded rod as a transmission mechanism to adjust the front and rear orientation of the excavation drill bit, and during the excavation operation, the first threaded rod is subjected to a strong reaction The force is very easy to wear the thread, resulting in a very short service life of the threaded rod, and this device installs the suction fan at one end of the telescopic pipe, and the dust collection cover is close to the excavation drill bit, and the small solid particles produced by the excavation operation during dust discharge are very easy to absorb. Into the pipeline, and then hit the impeller, damage the suction fan, the design is not reasonable
