Problems solved by technology

[0004] However, this anti-blocking protection device has disadvantages. Firstly, the reaction is not sensitive, and it is easily affected by the external environment. Its action is determined by the direction of the tent coal. If it is placed in the wrong position, it may cause no action; secondly, its reliability is not high. , the plant vibrates greatly, and the suspended detector is

Abstract

The invention discloses an anti-blocking device for a discharging chute. The anti-blocking device is arranged inside the discharging chute and is an infrared inductive switch. A mounting hole is formed in the side wall of the discharging chute, the infrared inductive switch penetrates through the mounting hole, and an inductive head of the infrared inductive switch faces a discharging port of the discharging chute. The distance between the inductive head of the infrared inductive switch and the discharging port is smaller than the sensing distance of the infrared inductive switch. By arranging the infrared inductive switch, the stability is improved.

Description

technical field [0001] The invention relates to the field of mining, in particular to an anti-blocking device for a feeding chute. Background technique [0002] At present, the transportation of raw coal and clean coal is basically carried directly by belts and chutes. Due to coal quality and other reasons, the chute is easy to be blocked, and the phenomenon of coal gushing out of the chute and stuffy head happens from time to time, which seriously affects the amount of coal carried and increases the number of workers. The labor intensity reduces the production safety, which is not conducive to the safe production of the coal preparation plant. [0003] The original chute anti-blocking switch uses a mercury-type anti-blocking switch, also called a tilt switch. Its parameters are AC220V, 1 normally open point (or 1 normally closed point), and the action angle is universal 20°-35°. The structure is: Suspended, the detector housing is made of stainless steel. Its working prin...
