Problems solved by technology

[0002]In the "three soft" coal seams, because the medium is relatively soft, it can be almost crushed by hand. It is soft and easy to fall off, so it is not possible to use explosives to blast the coal body during excavation. You can only use hand picks to drop coal and pneumatic picks to break the bottom. Four or five workers must be arranged to use hand picks and pneumatic picks to work, which consumes manpower and material resources, increases costs, and brings safety hazards to construction workers

Abstract

The invention relates to a combined type pneumatic pick suspended on an I-steel support of a coal mine. Four pneumatic picks are combined into the combined type pneumatic pick which is hung on the I-steel support of a coal mine roadway, and a hydraulic system is used for driving the combined type pneumatic pick to move so as to carry out coal seam tunneling, so that a conventional manual coal breaking manner is replaced, the labor intensity of workers is alleviated, the speed is increased, the efficiency is improved, the input of manpower and material resources is reduced, and the safety factors are improved. The combined type pneumatic pick swings from side to side by adjusting a direction adjustment air cylinder, so that the width range of tunneling of the combined type pneumatic pick is extended; the combined type pneumatic pick swings up and down by adjusting an upper height adjustment oil cylinder and a lower height adjustment air cylinder, so that the height range of tunneling of the combined type pneumatic pick is extended; the height range of tunneling of the combined type pneumatic pick can also be extended by an upper oil cylinder; the combined type pneumatic pick is pushed to tunnel continuously and forwards by pushing an oil cylinder and a telescopic cylinder.

Description

Technical field: [0001] The invention belongs to the technical field of coal mine machinery, and in particular relates to a coal mine I-beam support, suspension and combined air pick machine. Background technique: [0002] In the "three soft" coal seams, because the medium is relatively soft, it can almost be crushed by hand. During the excavation process of the coal road, the coal seam occurrence conditions are unstable, the coal seam is soft, and it is easy to fall off. Therefore, it is not possible to use explosives to blast the coal during excavation. The only way to work is to use hand picks to drop coal and pneumatic picks to break the bottom. This manual excavation method requires four or five workers to use hand picks and pneumatic picks in each shift for a single excavation face. It both consumes manpower and material resources, increases costs, and brings potential safety hazards to construction workers. Invention content: [0003] To sum up, in order to ove...
