Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushing devices, in particular to a coal crushing device. Background Art
[0002] As is well known, coal is a carbonized fossil mineral, usually used as fuel. After coal mining, since the coal has not been crushed, a crushing device is needed to crush large-particle coal, bringing convenience to subsequent processing, transportation and use.
[0003] The existing coal crushing devices do not have a dust reduction mechanism during use, resulting in a large amount of dust generated when large-particle coal is crushed, and splashing out from the feed inlet and the discharge outlet, causing environmental pollution and damage to the respiratory tract of the staff. At the same time, small-particle sputtering of coal during crushing can also cause injuries to personnel, which is not conducive to production, processing and use as a whole. Therefore, it is urgent to reduce dust, and for this reason, we have designed a coal crushing device. Content of the Utility Model
[0004] (1) Technical Problems to be Solved
[0005] In view of the deficiencies of the prior art, the utility model provides a coal crushing device, which solves the technical problems mentioned in the above background art.

A feed pipe is fixedly connected to the top of the crushing box, and a feed hopper is fixedly connected to the top of the feed pipe. On both sides of the inner wall of the feed pipe, there are staggered baffles. Two crushing wheels are installed inside the crushing box. One end of each crushing wheel is equipped with a motor, and each motor is installed on the box body. The bottom of the crushing box is connected to a discharge hopper. A plurality of support legs are arranged at the bottom of the discharge hopper. A water tank is installed on one side of the crushing box. A plurality of spray nozzles are installed at the top of the inner wall of the discharge hopper. A flow dividing plate is installed at the top of the discharge hopper, and a water pump is installed on the flow dividing plate. A connecting pipe is installed between the water pump and the water tank.
[0008] Further, the inside of the flow dividing plate is provided with flow channels communicated with each spray nozzle.
[0009] Further, the discharge hopper is inclined obliquely downward.
[0010] Further, each motor and the water pump are connected to an external power supply.
[0011] Further, a plurality of crushing heads are arranged on each crushing wheel.
[0012] Furthermore, a support block is provided at the bottom of each support leg, and an anti-slip coating is provided at the bottom of each support block.
[0013] (III) Advantageous Effects
[0014] Compared with the prior art, the present utility model provides a coal crushing device, which has the following advantageous effects:
[0015] In this coal crushing device, baffles are arranged in an interlaced manner in the feed pipe, and the dust during the crushing process is folded by the baffles, reducing the spillage of dust. At the top of the inner wall of the discharge hopper, a plurality of nozzles are provided and water is supplied through a water pump to dust the crushed coal blocks. The device has a simple structure, is easy to operate, and effectively reduces the air pollution caused by dust and the harm to the human body. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-3, a coal crushing device of the present utility model, comprising a crushing box 1, a feed pipe 2 fixedly connected to the top of the crushing box 1, a feed hopper 3 fixedly connected to the top of the feed pipe 2, baffles 4 arranged in a staggered manner on both sides of the inner wall of the feed pipe 2, two crushing wheels 5 installed inside the crushing box 1, a plurality of crushing heads arranged on each crushing wheel 5, a motor 13 installed at one end of each crushing wheel 5, each motor 13 being installed on the box body, a discharge hopper 6 connected to the bottom of the crushing box 1, the discharge hopper 6 being inclined obliquely downward, a plurality of support legs 7 arranged at the bottom of the discharge hopper 6, a support block arranged at the bottom of each support leg 7, and an anti-slip coating arranged at the bottom of each support block; a water tank 8 is installed on one side of the crushing box 1, water is contained in the water tank 8, a plurality of spray nozzles 9 are installed at the top of the inner wall of the discharge hopper 6, a flow dividing plate 10 is installed at the top of the discharge hopper 6, a flow channel communicating with each spray nozzle 9 is arranged inside the flow dividing plate 10, a water pump 11 is installed on the flow dividing plate 10, and a connecting pipe 12 is installed between the water pump 11 and the water tank 8:.
[0022] In summary, when the coal crushing device is in use, coal blocks are put into the feed hopper 3 and enter the crushing box 1 along the feed pipe 2. Then, the motor 13 drives the crushing wheels 5 to rotate to crush the coal blocks. Dust splashes upward and is folded by the staggered baffles 4, reducing the splash of dust. The crushed coal blocks slide out through the discharge hopper 6. During this process, the water pump 11 pumps the water in the water tank 8 into the spray nozzles 9 to reduce the dust of the coal blocks and reduce the splash of dust at the discharge port.
