Shield Bolter Mining Machine

Abstract

The invention relates to a shield type digging and anchoring machine, solving the problems that the conventional operation equipment is poor in safe reliability and complex in operation process and cannot meet the normal production needs of mines. The shield type digging and anchoring machine comprises a shield body, a cutting head, a drilling anchor supporting working platform, a rotary table feeder, a reversed loader, a self-moving belt conveyor and a dedusting air duct. The shield type digging and anchoring machine is characterized in that the shield body adopts a frame structure which is composed of a front shield body and a rear shield body connected with each other through a pushing hydraulic cylinder, and each of the front shield body and the rear shield body is composed of a shield body top and a shield body bottom which are supported and connected through a lifting hydraulic cylinder; the cutting head is arranged at the front end of the front shield body, and the cut-down coal and rock are transported out through the rotary table feeder, the reversed loader and the self-moving belt conveyor; the drilling anchor supporting working platform is arranged at the rear part of the rear shield body, and a top plate and two sides of a rear tunnel space are permanently supported under the screening of the shield body. The shield type digging and anchoring machine has the advantages of being reasonable in structural design, stable in supporting and moving and safe and reliable and realizes the concurrent job of digging and permanent supporting, and the operation rate and the digging efficiency of the digging and anchoring machine are significantly improved.

Description

technical field [0001] The invention relates to a fully-mechanized excavation device for tunneling and supporting operations in coal mine roadways, in particular to a shield-type bolter that advances along the roadway to realize integrated operations of driving, roadway support and advanced drilling. It belongs to the field of excavation machinery manufacturing and application. Background technique [0002] The tunneling operation of the roadway is the prerequisite for all other mining operations in the current mine mining, especially in the underground mining of coal mines. However, due to the substantial increase in the output of the mining face, accompanied by a large amount of roadway consumption, the tunneling cannot keep up with the contradiction of the mining needs Increasingly prominent in many mining areas. The low rate of roadway excavation is closely related to the way of excavation and support. [0003] Safe, fast and efficient roadway excavation and support te...
