Abstract

The invention discloses a comprehensive dredging machine. The comprehensive dredging machine comprises a crawler-free type dredging machine, a hydraulic support, a drilling machine, a scraper conveyor, a runner and the like. The upper end of the hydraulic support is provided with a main top beam, a front canopy, a back canopy and a cross beam; the dredging machine is arranged on a foundation; thefront and rear ends of the foundation are provided with a slope regulation jack respectively; one end of a front pushing and pulling jack is connected with the foundation of the dredging machine, andthe other end of the front pushing and pulling jack is connected with the hydraulic support; the rear of the dredging machine is provided with a self-advancing jack, and two sides of the foundation are provided with a side push cylinder respectively; and the drilling machine is arranged below the main top beam or the back canopy; and the runner is arranged behind the hydraulic support and is connected with a rear push and pull jack arranged on the hydraulic support by an anchor chain and a pulley. The comprehensive dredging machine has the advantages of parallel operation of hole drilling andsupporting, and coal cutting of a development machine, a roadway turns flexibly, the turning radius is small, the turning speed is high, the tunneling speed is high, and the safety is guaranteed.

Description

technical field

[0001] The invention relates to a bolter, in particular to a comprehensive bolter with the functions of digging, transporting, supporting, paving and anchoring integrated. Background technique

[0002] At present, there are four methods of roadway excavation in the coal industry at home and abroad: one is to adopt the blasting method to excavate; the other is to use the cantilever type roadheader to excavate; Use above-mentioned four kinds of excavation methods and all need coal seam roof to be relatively stable, especially the third, fourth, only can bring into play its peculiar effectiveness under the firm situation of roof. Since the 1980s, my country has successively introduced foreign cantilever roadheaders, continuous miners and a small number of bolter units. However, when using these three types of roadheaders for tunneling, it is necessary to increase the power and increase the deadweight at the same time. Enhance its stability, and the driving effic...
