[0004] When the noise reduction jaw crusher crushes materials, there is no dust removal structure at the feed port of the box body. Therefore, the dust generated by the crushed materials will be discharged directly from the feed port as the box body shakes, which not only pollutes the environment, but also affects the health of the operators around who are in this environment for a long time. At the same time, the buffering noise reduction structure is set at the bottom of the box body, and the main force of the jaw crusher moves in the horizontal direction, so the buffering noise reduction effect is not good.

At the same time, the above-mentioned buffering noise reduction structure is set at the bottom of the box body, and the main force of the jaw crusher moves in the horizontal direction, so the buffering noise reduction effect is not good.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a noise-reducing jaw crusher, comprising a bottom plate and a vertical plate, a pair of vertical plates being fixedly connected to the upper surface of the bottom plate, a pair of telescopic rods being fixedly connected to the inside of the right vertical plate, a crusher body being fixedly connected to the left side of the telescopic rods, two pairs of wheels being fixedly connected to the bottom of the crusher body, and the lower outer walls of the wheels are gap-matched with the inner walls of the slide grooves of the bottom plate, a box body being fixedly connected to the left side of the upper surface of the crusher body, a fan being fixedly connected to the right side of the box body, and an air intake pipe and an air outlet pipe of the fan being respectively connected to the inside of the crusher body and the box body, a filtering mechanism being installed inside the box body, and a noise reduction mechanism being installed on the outer wall of the crusher body.

[0012] Beneficial Effects

[0013] The utility model provides a noise reduction jaw crusher, which has the following beneficial effects:

[0014] When the movable jaw plate in the crusher body is working, the crusher body will be driven by the crushing force to drive the wheel to move on the bottom plate. At this time, the crusher body will drive the trapezoidal tooth plate to move, so that the trapezoidal tooth plate squeezes the gear, and the gear drives the concave plate to move on the vertical rod. At the same time, the concave plate cooperates with the second horizontal plate to squeeze the spring, causing the spring to undergo elastic deformation. In this way, the spring cooperates with the shock absorber to dampen the crusher body and reduce the noise generated when it shakes, so the noise reduction effect is better.

[0015] When the movable jaw and the stationary jaw in the crusher body are crushing the material, the fan can be started to generate suction through the fan's air intake pipe to suck in the dust during crushing, and then discharge the dust into the box through the fan's air outlet pipe. The dust is filtered through the filter plate, the second filter layer and the first filter layer in turn, and then discharged through the opening on the left side of the box, thus avoiding environmental pollution and minimizing the harm to the health of surrounding operators.

[0016] The materials to be crushed can be discharged into the crusher body through the feed hopper, and at the same time, the transmission assembly on the moving jaw plate cooperates with the static jaw plate to crush the falling materials, and then the electric push rod is started to drive the baffle to move back and forth regularly, so that the crushed materials can continue to fall down, and then the motor is started to make the output shaft of the motor drive the conveying auger to rotate. Since the conveying auger is a bidirectional symmetrical structure, the material can be transported to the middle and discharged from the discharge hopper to complete the material crushing.
