[0015] Beneficial Effects

[0017] 1. The protective structure of a coal mine belt conveyor is provided with a cooling mechanism, a driving mechanism and a valve mechanism. In the initial state, the arc sponge pad and the strip sponge pad do not contact the outer wall surfaces of the conveying roller and the conveying belt, and the lifting valve plate forms a blockage on the inner middle part of the drain pipe. When the equipment needs to cool down the conveyor roller and the conveyor belt after long-term use, the telescopic end of the electric telescopic rod is controlled to drive the force-applying slider to move to the left, and the force-applying slider drives the arc sponge pad on the arc-shaped fitting seat to move to the left through the connecting bracket to fit the outer wall of the conveyor roller. During the movement of the force-applying slider to the left, the bottom wall of the force-applying slider squeezes the top wall of the stress slider, forcing the stress slider to drive the strip-shaped fitting seat to move downward through the reset slide rod along the reset slide hole to stretch the reset spring and drive the strip sponge pad to fit the outer wall of the conveyor belt. The strip-shaped fitting seat also drives the lifting valve plate at the bottom of the lifting slide rod to move downward along the inside of the storage slide groove through the lifting bracket to open the drain pipe, so that the cold water in the cooling water tank is introduced into the arc sponge pad and the strip sponge in turn through the drain pipe, the three-way joint and the two water inlets under the action of its own gravity. The strip sponge pad is moved upwards through the strip fitting seat and resets under the elastic force of the reset slide hole, and the strip fitting seat drives the lifting valve plate at the bottom of the lifting slide rod to move upwards through the lifting bracket to block the middle of the drain pipe, so that the cold water inside the cooling water tank stops being discharged. The above operation is simple and practical, so that the arc sponge pad and the strip sponge pad on the equipment do not need to always keep in contact with the outer wall surfaces of the conveyor roller and the conveyor belt, which reduces the wear on the arc sponge pad and the strip sponge pad and extends the service life of the equipment.

[0018] 2. The protective structure of the coal mine belt conveyor is provided with a driving mechanism. The device only drives the arc sponge pad to move horizontally, the strip sponge pad to move vertically, and the switch operation of the drainage pipe through an electric telescopic rod. The structure is reasonable and compact, which reduces the use cost of the equipment and improves the practicability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
