An automatic rod feeding device for a rock bolter used in coal mines

Abstract

The invention belongs to the technical field of jumbolter equipment for coal mines, and particularly relates to an automatic rod feeding device of a jumbolter for a coal mine. The problem that the operation efficiency of an existing roof bolter for the coal mine is low, thus the time of the support process of a roadway is long, and consequently the landslide risk of the roadway is increased is solved. The automatic rod feeding device comprises an anchor storeroom support, a rotatable anchor rod support plate is located at the bottom of the anchor rod storeroom support and arranged horizontally, the anchor rod support plate is provided with anchor rods arranged in a circle shape, a rotating center shaft arranged vertically is fixed to the position, on the circle center of the anchor rod support plate, of the anchor rod storeroom support, an anchor grasping mechanical arm fixing sleeve tube is arranged on the upper part of the rotating center shaft in a concentric mode, the anchor grasping mechanical arm fixing sleeve tube is provided with an anchor grasping mechanical arm, and a hydraulic driving device fixedly connected with the upper surface of a second cross arm is arranged at the top of the anchor rod storeroom support. According to the automatic rod feeding device, the changing and mounting efficiency of the anchor rods is effectively improved, the time of the support process of the roadway is shortened, and the landslide risk of the roadway is reduced.

Description

technical field [0001] The invention belongs to the technical field of rock bolter equipment for coal mines, and in particular relates to an automatic rod feeding device for rock bolters for coal mines. Background technique [0002] In the coal mining process, generally all use the rock bolter that coal mine is used to drill the coal seam, then inject anchoring agent into the drilled hole and insert the anchor rod in the hole, to realize the support to the roadway. However, when the rock bolt rig in the prior art is carrying out bolt support, after a bolt is finished, the next bolt needs to be manually installed by the worker, and the operation efficiency is low, so that the supporting process of the roadway takes a long time. Long, increasing the risk of landslides in the roadway. Contents of the invention [0003] The present invention provides an automatic rod feeding device for a coal mine bolter in order to solve the problem that the existing coal mine bolter has low...
