[0024] In order to realize the function of absorbing dust when crushing, the crushing device 2 comprises an electric conveying belt 20, the bottom of the electric conveying belt 20 is fixedly provided with supporting legs 21, the electric conveying belt 20 is installed on the working plane 1 through the supporting legs 21, one side of the electric conveying belt 20 is provided with a crusher 22, a pair of crushing rollers 26 are rotatably installed in the crusher 22, the crushing rollers 26 divide the crusher 22 into two spaces, i.e. a crushing cavity 23 and a collecting cavity 24, a collecting box 28 is slidably installed in the collecting cavity 24, one end of the crushing roller 26 located at one side is provided with a first motor 25, the other end of the two crushing rollers 26 is provided with a gear 27, and the two gears 27 are meshed with each other. The dust absorption device 3 comprises a negative pressure fan 30, the negative pressure fan 30 is fixedly installed on one side of the crusher 22 close to the crushing cavity 23, a clamping plate 31 is rotatably installed on one side of the negative pressure fan 30, filter screen cotton 32 is slidably installed in the negative pressure fan 30, and a fan 33 is installed in the negative pressure fan 30. By placing waste on the electric conveying belt 20, the electric conveying belt 20 will transport the waste to one side of the crusher 22, when the waste enters the crusher 22, the first motor 25 will drive the two crushing rollers 26 to rotate through the gears 27, so as to crush the waste by the crushing rollers 26, and the fan 33 in the negative pressure fan 30 will rotate to generate negative pressure to generate suction force on the crushing cavity 23, so as to suck the dust generated above the crushing cavity 23 during crushing, thereby avoiding dust leakage.
[0025] Example 2: as Figures 1-4, in order to realize the function of continuous crushing work, the anti-overflow device 4 includes an anti-overflow baffle 41 fixedly installed on one side of the crusher 22 close to the electric conveying belt 20, a connecting pipe 40 fixedly installed between the crusher 22 and the anti-overflow baffle 41, the connecting pipe 40 being in communication with the interiors of the crusher 22 and the anti-overflow baffle 41 respectively, an inlet cloth strip 42 installed at an end of the anti-overflow baffle 41 away from the crusher 22, a first rotating shaft 43 rotatably installed at an end of the crusher 22 close to the anti-overflow baffle 41, an internal blocking cloth 44 fixedly installed on the first rotating shaft 43, and a counterweight 45 fixedly installed at an end of the internal blocking cloth 44 away from the first rotating shaft 43. In order to realize the continuous crushing mode, the waste is placed in piles on the electric conveying belt 20, and the electric conveying belt 20 is continuously worked. When the waste is placed, it is placed in piles, and a certain distance should be maintained between each pile of waste, which should be no less than the length in the anti-overflow baffle 41. When the waste on the electric conveying belt 20 enters the crusher 22, it will first pass through the inlet cloth strip 42 and then enter the anti-overflow baffle 41. At this time, the internal blocking cloth 44 blocks the opening of the crusher 22 to avoid dust overflow in the crusher 22. Then the waste advances and lifts the internal blocking cloth 44. At this time, the anti-overflow baffle 41 loses the obstruction and naturally drops to close the opening. The interior of the anti-overflow baffle 41 is communicated with the crushing cavity 23 through the connecting pipe 40. When the fan 33 works, it will synchronously suck the air in the anti-overflow baffle 41 through the connecting pipe 40, so as to suck away a small amount of dust overflowing from the internal blocking cloth 44, avoiding its overflow to the outside. The counterweight 45 in the internal blocking cloth 44 can make the internal blocking cloth 44 always keep falling, so that when the waste lifts the internal blocking cloth 44, the internal blocking cloth 44 can always be attached to the waste, thereby reducing the gap between the waste and the internal blocking cloth 44, and reducing the dust overflow in the crushing cavity 23. The remaining features are the same as those in example 1.
[0026] The working principle is that: by placing the waste on the electric conveyor belt 20, the electric conveyor belt 20 will transport the waste to the side of the crusher 22, when the waste enters the crusher 22, the first motor 25 will drive the two crushing rollers 26 to rotate by the gear 27, so as to crush the waste by the crushing roller 26, and the fan 33 in the negative pressure fan 30 will rotate to generate negative pressure to the suction area of the crushing cavity 23, so as to suck the dust generated above the crushing cavity 23 during crushing, avoid dust leakage, in order to realize the continuous crushing mode, the waste is placed on the electric conveyor belt 20, the electric conveyor belt 20 is continuously working, when placing the waste, it is placed in piles, and a certain distance should be maintained between each pile of waste, and the distance should be not less than the length of the anti-overflow baffle 41, preferably, when the waste on the electric conveyor belt 20 enters the crusher 22, it will first pass through the entrance cloth 42, and the waste will first lift the entrance cloth 42 into the anti-overflow baffle 41, at this time, the internal blocking cloth 44 blocks the opening of the crusher 22 to avoid dust overflow in the crusher 22, then the waste advances to lift the internal blocking cloth 44, at this time, the anti-overflow baffle 41 loses the obstruction and naturally falls to close the opening, the inside of the anti-overflow baffle 41 is communicated with the crushing cavity 23 through the connecting pipe 40, and the fan 33 works to synchronously suck the air in the anti-overflow baffle 41 through the connecting pipe 40, so as to suck away a small amount of dust overflowing from the internal blocking cloth 44, avoiding its overflow to the outside, and the counterweight 45 in the internal blocking cloth 44 can make the internal blocking cloth 44 always fall down, so that when the waste lifts the internal blocking cloth 44, the internal blocking cloth 44 can always be attached to the waste, thereby reducing the gap between the waste and the internal blocking cloth 44, and reducing the dust overflow in the crushing cavity 23.
