Linkage control device for mining belt conveyor and water spraying mechanism

A mining belt conveyor and water spraying mechanism linkage control device comprises a sensing mechanism arranged on a bottom frame of a belt conveyor, the sensing mechanism is used for sensing raw coal on the belt conveyor, the sensing mechanism comprises a rotating rod rotationally arranged on the bottom frame and a sensing plate fixedly arranged on the bottom frame, and the rotating rod comprises a rod body rotationally connected with the bottom frame; a vertically-upward contact rod is arranged at the end, close to the belt conveyor, of the rod body, a vertically-downward induction rod is arranged at the other end of the rod body, and the induction rod and the induction plate are matched to form a linked switch used for controlling the water spraying mechanism to be started or stopped. When an upper belt of the belt conveyor is pressed by raw coal to deform, the sensing rod can be driven to be separated from the sensing plate by pressing the contact rod downwards, and the rod body is further connected wit
