Abstract

The invention discloses a digging and anchoring device for collecting coal by a spiral drum, belongs to the technical field of digging and anchoring devices, and solves the technical problems. The digging and anchoring device is simple in structure and convenient to popularize. The invention adopts the technical scheme as follows: the digging and anchoring device comprises a digging and anchoring device body, a cutting part, an anchor rod drill bit and a traveling part, wherein the cutting part is positioned at the front part of the digging and anchoring device body; the anchor rod drill bit is arranged on the digging and anchoring device body and positioned on the rear side of the cutting part; the traveling part is arranged at the bottom of the digging and anchoring device body; a coal shovel plate is arranged at the bottom of the cutting part; one end of the coal shovel plate is arranged on the digging and anchoring device body; the spiral drum used for collecting the coal is arranged on the coal shovel plate; a scraper conveyer is arranged in the middle of the digging and anchoring device body and used for conveying the coal collected by the spiral drum to a coal transport hopper. The digging and anchoring device can be widely applied to coal mining.

Description

technical field [0001] The invention discloses an anchor digging device utilizing a spiral drum to collect coal, and belongs to the technical field of anchor digging devices. Background technique [0002] Coal mine roadway excavation includes two operations of excavating the roadway space and supporting the roadway. Now most of the coal roadway excavation in our country adopts cantilever type roadheader to excavate the roadway bolt support, and the bolt support has occupied more than two-thirds of the entire roadway excavation time. Therefore, the bolt support is the main factor affecting the tunneling speed of the coal roadway. Since the 1980s and 1990s, the United States and Europe began to develop bolt-digging devices that can dig coal roadways and bolt support at the same time. At present, my country has introduced and used two types of bolt-digging devices, MB670 from Sandvik Company of Sweden and 12CM30 from JOY Company of the United States. The structure is basically...
