Longitudinal tearing detection device for barrier type belt conveyor

The utility model discloses a longitudinal tearing detection device of a barrier type belt conveyor. The utility model aims to solve the problem that longitudinal cracks of a belt cannot be found, so that the whole conveying belt is possibly scrapped. The dust-proof device comprises a dust-proof box (9), wherein the dust-proof box is used for preventing external dust from entering the dust-proof box; the at least two groups of infrared correlation switches (8) are used for detecting blanking of the conveying belt; the dust isolation box comprises a square box body (1), the shape of the top of the square box body is the same as that of the conveying belt, a square ring air pipe (2) is fixed to the top of the square box body, and the square ring air pipe is communicated with an air inlet pipe (3). The longitudinal tearing detection device is used for longitudinal tearing detection of the belt conveyor. 一种阻隔式皮带输送机纵撕检测装置。是为了解决皮带发生纵裂时不及发现，就有可能使得整条运输带报废的问题。本实用新型组成包括：隔尘箱（9），所述的隔尘箱用于阻隔外部灰尘进入到隔尘箱内；至少两组红外对射开关（8），所述的红外对
