Embodiment 1

[0031] This embodiment provides an automatic rod-feeding device for a coal mine bolter, which includes a bolt storage mechanism, a first manipulator, a second manipulator and a fixing seat;

[0032] The anchor rod storage mechanism includes a lower supporting plate 301, a rotating power part 302, a central shaft 303, a lower sub-dial 304, an upper sub-dial 305 and an upper fixed retaining ring 306;

[0033] The lower supporting plate 301 is circular, and its edge protrudes upwards.

[0034] The rotating power part 302 can be a motor, or a power device such as a hydraulic motor. On rotating parts, such as rotors of electric motors and hydraulic motors; the axis of the central shaft 303 is perpendicular to the lower support plate 301 .

[0035] The center of the lower dial 304 is provided with a first through hole, and the side wall of the lower dial 304 is provided with a plurality of semicircular grooves along the axial direction of the lower dial 304. The lower part can be ...

Abstract

The invention discloses an automatic rod feeding device for a mine anchor rod drilling machine. The device comprises an anchor rod storing mechanism, a first manipulator, a second manipulator and a fixing seat. According to the device, an anchor rod is stored into semicircular grooves in an upper index plate and a lower index plate through the anchor rod storing mechanism; the anchor rod is grasped, conveyed and positioned through the first manipulator and the second manipulator; therefore, automatic conveying of the anchor rod is achieved; the replacing efficiency of the anchor rod and a drilling rod can be increased; the time of supporting the tunnel is reduced; the risk of collapse of the tunnel is reduced.

Description

technical field [0001] The invention relates to parts of a rock bolter used in coal mines, in particular to an automatic rod feeding device of a rock bolt used in coal mines. Background technique [0002] In the coal mining process, the coal seam is generally drilled with a rock bolter, and then the drilled hole is sprayed with anchoring agent, and the bolt is inserted into the hole to support the roadway. But the bolter in the prior art needs to replace the drill rod of the bolter with a bolt after the hole is drilled, and this process is all done manually by workers, and the work efficiency is low, so that the support of the roadway The process takes a long time, which increases the risk of roadway collapse. Contents of the invention [0003] The object of the present invention is to provide an automatic rod feeding device for a rock bolter used in coal mines, which can automatically convey the bolts and improve the working efficiency. [0004] The present invention so...
