Description

Dustpan type material guiding device capable of preventing coal falling from deviating Technical Field The utility model belongs to the technical field of coal mine tunneling transportation, and particularly relates to a dustpan type material guiding device for preventing falling coal from deviating. Background In the tunneling operation process of the bottom suction roadway, after the gangue cutting operation (related to the rock roadway part) is finished, a remarkable problem is often encountered that the gangue backlog phenomenon is easy to occur in the area of 5-10 meters behind the unit and the tail of the belt conveyor. The problem is complex and various in root, but the core factors can be summarized into two points, namely that the gangue is instantaneously sprung up and falls into an unexpected area due to the deviation between the gangue and the gangue falling point of the transfer belt in the conveying process, and the phenomenon of deviation possibly occurring in the belt running process, so that the gangue is scattered from the belt and cannot fall into the effective bearing range of the belt conveyor accurately. The gangue deviating from the track not only increases the cleaning difficulty of the working face, but also forces staff to frequently adjust the belt position of the rubber belt conveyor, and the efficiency and the safety of tunneling operation are seriously affected. In view of the current situation, and in combination with the specific tunneling operation environment characteristics of the site, the utility model provides an innovative solution, namely, designs and applies a dustpan type material guiding device for preventing the falling coal (gangue) from deviating. Disclosure of utility model The utility model aims to solve the problem that gangue is instantaneously sprung and falls off due to the fact that the gangue falling center point and the transfer belt are not right in running track, and cannot accurately fall on a rubber belt conveyor.
