Description

Technical Field

[0001] The utility model relates to the technical field of prying machines, in particular to an underground manual safety prying machine. Background Art

[0002] In ore mining, in order to ensure the safety of mining, personnel are required to manually pry the pumice in the mine room and the excavation face during the mining and excavation process. Only by prying the prying in the underground mine room and the excavation face can the underground mine room and the excavation face be guaranteed to be safe and effective for mining, mining and prospecting. Due to the difficulty of the underground workers' prying operation, there will be accidents of pumice hitting people and roof falling, which is extremely unfavorable to the future safety production and long-term development of the mine.

[0003] After searching, the utility model patent with announcement number CN217813461U discloses a manual safety prying machine for underground mining, including a frame; a fixed plate is fixedly installed on the right end of the frame; a symmetrical functional reversing handle is installed on the top of the fixed plate; a rotating drum is installed at the lower end of the left end of the frame; a connecting plate is fixedly installed on the left wall of the fixed plate; a bearing plate is installed on the upper end of the top of the connecting plate; and a symmetrical guide hole is opened at the left end of the bearing plate; in this patent, the position of the pneumatic pick can be adjusted up and down, so as to impact the loose part of the rock mass, and the rough stones impacted will fall to the ground, achieving the purpose of cleaning the rough stones. However, the above patent still has the following shortcomings: although the angle and up and down position of the pneumatic pick can be adjusted by the boom, the height of the pneumatic pick needs to be adjusted synchronously with the angle of the pneumatic pick, which is not convenient to ensure that the pneumatic pick can face the prying position; and the working angle of the pneumatic pick can only be consistent with the angle of the boom, and it is not convenient to adjust when the angle of a certain working height of the pneumatic pick needs to be changed. For this reason, we propose an underground manual safety prying machine. Utility Model Content
