[0035] To facilitate the crushing of scrap steel, a control motor 9 is installed on the outer surface of the rectangular bin 1. A round shaft 10 is installed at the output end of the control motor 9, and a crushing roller 11 is installed on the outer surface of the round shaft 10. The crushing roller 11 is located inside the rectangular bin 1.

[0038] Specifically, the working process or working principle of a waste steel crushing and dust reduction device is as follows: Currently, the method of crushing waste steel is to put the waste steel into the crushing equipment. Since the waste steel has been stored for a long time, a lot of dust will fall on the outer surface of the steel. This results in a large amount of dust being generated during the crushing of waste steel. This dust will not only pollute the environment, but also cause harm to the workers. Therefore, this device was designed to solve this problem.
[0039] This device can reduce dust generated during scrap steel crushing, preventing large amounts of dust from escaping and polluting the environment. It also protects workers from harm. Specifically, the device is connected to an external power source. When crushing scrap steel, the cover plate 33 is rotated to open the top of the conical chamber 2. Both the linkage rod 31 and the cover plate 33 are set to damped rotation, allowing scrap steel to be added from the conical chamber 2 into the rectangular chamber 1 without obstruction by the cover plate 33. Then, the control motor 9 drives the circular shaft 10 to rotate. Two circular shafts 10 are installed inside the rectangular chamber 1, with one end extending out of the rectangular chamber 1. Each circular shaft 10 is equipped with a crushing roller 11. The crushing teeth on the two crushing rollers 11 are staggered to improve the crushing effect on the scrap steel.
[0040] The control motor 9 drives one of the circular shafts 10 to rotate, and the first gear 12 rotates with the circular shaft 10, and the first gear 12 is connected with the second gear 13, and the second gear 13 drives the other circular shaft 10 to rotate, so that the two crushing rollers 11 rotate to crush the scrap steel and meet the use.
[0041] After the scrap steel is added to the rectangular bin 1, the shutter 33 can be rotated to fit the top of the conical bin 2, and the shutter 33 is provided with two shutters 33, which are fitted together at the top of the conical bin 2, and the two shutters 33 can be closed together to avoid a large amount of dust from the top of the conical bin 2, thereby achieving the effect of dust reduction.
[0042] Furthermore, in order to improve the dust reduction effect, the crushing roller 11 can also extract water from the outside through the liquid extractor 43, and the water is extracted and transported to the water conveying pipe 42, and the water conveying pipe 42 transports the water to the spray pipe 41, and the spray pipe 41 is provided with a plurality of spray heads, which are communicated with the inside of the water conveying pipe 42, and the water outlet hole of the spray head is very small, so that the water sprayed from the inside of the spray head is in the form of water mist, and all the spray heads can spray water at the same time to increase the water mist in the rectangular bin 1, and the water mist can condense the particles in the dust into large blocks and fall down.
[0043] In the above manner, the dust generated during the crushing of scrap steel can be reduced, the environment can be protected from pollution, and the workers can be protected from harm.
[0044] After the crushing roller 11 crushes the scrap steel, it is discharged from the discharge bin at the bottom of the rectangular bin 1, which meets the use.
