Boring machine

Abstract

The invention discloses a boring machine, which comprises a main body part (1), and also comprises a main protecting plate (2) which is arranged above the main body part (1) towards the boring direction of the boring machine. When the boring machine is positioned in a harder terrane and needs blasting to carry out auxiliary boring, the main protecting plate (2) can block the small broken rocks generated by the blasting so as to prevent the collapsed rocks from damaging the main body part (1), thereby improving the self-protecting ability of the boring machine, preventing the boring machine from being damaged in the blasting process, and reducing maintenance cost; and the boring machine does not need to be away from the working face when the blasting is carried out in a drift, thereby, thetravel cost is saved, and the use cost of the boring machine is reduced.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a boring machine. Background technique [0002] With the rapid development of my country's economic construction, the coal industry continues to develop in the direction of mechanization and automation, and comprehensive mechanized mining equipment is more and more widely used in coal production under various geological conditions. [0003] In the operation of mechanized mining, the roadheader is one of the main mining equipment, and the excavation of the roadway is realized through the rotary cutting of the cutting head. During the excavation process of coal mine roadway, the roadheader is mainly used to excavate coal rock, semi-coal rock or rock roadway. The hardness of coal rock and semi-coal rock is low, and the roadheader can usually excavate normally, while the hardness of rock roadway is relatively high. , roadheaders are generally only able to economically excav...

Problems solved by technology

However, in the process of blasting with explosives, there will be a lot of rock fragments that burst out at high speed, and these rock fragments may hit the operating table, fan and fuel tank of the roadheader, causing serious damage to the key components of the roadheader. Therefore, it is usually necessary to keep the roadheader away from the working face in the working condition of blasting excavation (generally, the roadheader needs to be moved back about 30 meters to 50 meters), and the roadheader is moved back to continue working after the blasting is completed. The size of the roadheader is relatively large, and the related equipment is more and more complicated. When the roadheader moves, other related equipment also needs to move with it. It is difficult to transfer the huge working system, which increases the work cost.
