Anchor digging machine

Abstract

The invention discloses a bolt-digging integrated machine, which comprises a machine frame, a cutting arm, a coal conveying channel, a shovel plate assembly and a jacking anchor device. The shovel assembly includes the first main shovel, the second main shovel, the coal inlet channel, the first auxiliary shovel, the second auxiliary shovel, the first rotator and the second rotator, the first auxiliary shovel and the second The opening angle of the auxiliary shovel can be adjusted; the top anchor device includes a drill mount, a rock bolt and a linear drive assembly, and the rock bolt is rotatably arranged on the drill mount around a third axis, and the third axis is along the first horizontal axis. The linear drive assembly is installed on the frame, and the linear drive assembly is connected with the drilling rig mounting base so as to drive the drilling rig mounting base and the bolter to move along the second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction. The integrated bolter digging machine of the present invention can support the top of the roadway in a large range, and can also adjust the width of the blade assembly according to the width of the roadway.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery, in particular to an integrated bolt digging machine. Background technique [0002] The integrated bolt and digger is widely used in coal mining, and the integrated machine for digging and anchor needs to continuously support the coal mine roadway during the process of coal mining. The construction roadway of the integrated machine for mining and bolting is mostly rectangular, and the top of the roadway needs to be supported in multiple directions and in a large range during the coal mining process. [0003] The jacking and anchoring device of the integrated bolter digging machine in the related art can only support the top of the roadway at a fixed position, and cannot meet the construction requirements for large-scale support of the top of the roadway and vertical support of bolts. [0004] In addition, the coal cut by the cutting drum of the integrated bolter digging machine is col...
