Description

Technical Field

[0001] The utility model relates to the technical field of granite crushing, in particular to a granite crushing device. Background Art

[0002] Granite is an igneous rock formed by the cooling of magma below the earth's surface. Its main components are feldspar and quartz. Granite has a uniform structure, beautiful color, and hard texture, and is commonly used in the construction industry, such as in the demand for sand in the construction of infrastructure such as high-speed railways, highways, airports, and bridges. After granite is mined, it needs to be crushed for convenient transportation.

[0003] Traditional granite crushing devices often generate a large amount of dust during the crushing process, which not only causes serious environmental pollution but also poses a threat to the health of operators. Therefore, we propose a granite crushing device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that a large amount of dust generated during the crushing of granite is not treated in the prior art, resulting in environmental pollution and threatening the physical health of operators, and to propose a granite crushing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A granite crushing device includes a crushing box, the crushing box is hollow up and down, the bottom of the crushing box is fixedly connected with a dust reduction bin, and the crushing box is communicated with the dust reduction bin. The top of the crushing box is rotatably connected with an eccentric shaft. One end of the eccentric shaft is fixedly connected with a driven multi-groove synchronous pulley, and the other end of the eccentric shaft is fixedly connected with a flywheel. The device further includes:

[0007] A crushing assembly, which is arranged inside the crushing box and is used for crushing granite;

[0008] A conveying assembly, which is arranged inside the dust reduction bin and is used for conveying the crushed granite to the outside of the device;

[0009] A dust reduction assembly, which is arranged inside the dust reduction bin and is used for reducing the dust generated during the crushing of granite.

[0010] In a possible design, the crushing component includes a moving jaw, the moving jaw is sleeved on an eccentric shaft, and the moving jaw extends into the interior of the crushing chamber. One side of the moving jaw is fixedly connected with a movable jaw plate. On the inner wall of one side of the crushing chamber close to the movable jaw plate, a fixed jaw plate is fixedly connected. On the side of the moving jaw away from the fixed jaw plate, an elbow plate and a spring pull rod are rotatably connected, and the elbow plate is located above the spring pull rod. One end of the spring pull rod away from the fixed jaw plate is rotatably connected with the inner wall of one side of the crushing chamber. A U-shaped block is fixed on the inner wall of one side of the crushing chamber, and one end of the elbow plate away from the fixed jaw plate extends into the U-shaped block. At the top of the dust-removing chamber, an AC motor is fixedly connected. The output end of the AC motor is fixedly sleeved with a driving multi-groove synchronous pulley, and the driving multi-groove synchronous pulley and a driven multi-groove synchronous pulley are connected by a plurality of belts.

[0011] In a possible design, the conveying component includes a roller motor, the roller motor is fixedly arranged on the inner walls on both sides of the dust-removing chamber. A transmission cylinder is rotatably connected in the dust-removing chamber, and the roller motor and the transmission cylinder are connected by the same conveyor belt.

[0012] In a possible design, the dust-removing component includes two spray pipes, the two spray pipes are respectively arranged on the outer walls on both sides of the dust-removing chamber, and the two spray pipes are located above the conveyor belt. A plurality of spray heads are equidistantly arranged on the two spray pipes, and the plurality of spray heads respectively penetrate through the dust-removing chamber and extend into the interior of the dust-removing chamber.
