Waste rock throwing equipment suitable for fully mechanized coal mining face roadway

Abstract

The invention discloses waste rock throwing equipment suitable for a fully mechanized coal mining face roadway. The waste rock throwing equipment comprises a waste rock throwing belt inclining towards a filling area, a block cover frame arranged right above the waste rock throwing belt, crushing and angle grinding devices, first guide rails and a monitoring device; the multiple crushing and angle grinding devices are mounted in the block cover frame and are arranged in the conveying direction of the waste rock throwing belt, and the distances between the lower ends of the crushing and angle grinding devices and the upper surface of the waste rock throwing belt are equal; the first guide rails are symmetrically arranged at the left side and the right side of the blocking cover frame, the first guide rails and the crushing and angle grinding devices are longitudinally arranged in an alternative manner, and a set of first guide rail is installed between every two adjacent crushing and angle grinding devices; and the monitoring device is mounted on the first guide rails and clamped at the left side and the right side of the waste rock throwing belt.

Description

technical field [0001] The invention relates to the technical field of roadway gangue throwing, in particular to a gangue throwing device suitable for the roadway of a fully mechanized mining face. Background technique [0002] During the coal mining process, a large amount of gangue will be produced, and the abandoned roadway after mining can be used as a storage of gangue to enhance the support strength of the roadway after mining. In the existing gangue throwing equipment, in the process of throwing gangue into the landfill, the gangue is directly thrown into the roadway filling area, resulting in different sizes of gaps between the gangue filled in the roadway filling area, resulting in the waste rock filling The relative density of the waste rock is relatively low, thereby reducing the supporting strength of the gangue, and the gangue is prone to rolling down during the stacking process, making the construction environment more dangerous. [0003] Therefore, those skil...
