Mining touch sensor

Abstract

The invention discloses a mining touch sensor. The mining touch sensor comprises a main shell body, the upper part of the main shell body is fixedly connected with a handle hrough a butterfly nut anda first cross-shaped screw in a matched mode, a base is connected to the bottom of the main shell body, the outer side wall of the base is attached to the inner wall of the main shell body, and a sealing groove is formed in the side wall of the base; a second sealing ring is arranged in the sealing groove, the base is connected with a circuit board through a stud, a vibration sensor is fixed on the circuit board, the vibration sensor is connected with the circuit board, the circuit board and the vibration sensor are both located inside the main shell body, a chain is further welded to the base, and the chain is located outside the main shell body. According to the sensor, other sensor pieces are all arranged in the main shell body, sealing rings are arranged at multiple positions of a mining waterproof suspension type touch control sensor, the sealing performance is good, the induction failure in a dust humid environment is avoided, and the service life of the mining touch sensor is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a mine-used touch sensor. Background technique [0002] Mine touch sensors are mostly used for dust control hosts. The working scene is mainly used above the coal conveyor belt. When coal materials pass by on the detection belt, the coal materials touch the touch chain of mine touch sensors. The touch sensor Output a level signal to the dust suppression host, and the dust suppression host controls the solenoid valve to sprinkle water and spray dust. At present, the mining touch sensor has the following problems: 1. At present, most touch sensors need to be rotated to fix after wiring, causing the cable at the terminal to rotate accordingly, which is easy to cause the wire to twist and disconnect, which affects the sensing; 2. The environment in the mine is humid , Sprinkling and dust suppression will regularly carry out sprinkling operations, which will easily cause the sensor's w...
