It also includes a driving box 3, a crushing roller 4, a rotating rod 5, a screen 6, a spring 7 and a discharge port 8; the box body 1 is fixedly connected to the driving box 3; the box body 1 is rotatably connected to a pair of crushing rollers 4, and the crushing rollers 4 are connected to the driving box 3; the box body 1 is rotatably connected to the rotating rod 5; the rotating rod 5 is fixedly connected to a screen 6, and the screen 6 is arranged at an angle; the screen 6 is fixedly connected to two springs 7, and the spring 7 is fixedly connected to the box body 1; the box body 1 is provided with a discharge port 8, and the end of the screen 6 close to the spring 7 is supported by the discharge port 8.

It also includes an electric roller 101, a paddle 102 and a stirring blade 103; the bottom of the box body 1 is set as a collecting area 1a; the box body 1 is fixedly connected to the electric roller 101; the rotating part of the electric roller 101 is fixedly connected to a plurality of paddles 102, and the paddles 102 correspond to the screen 6; the rotating part of the electric roller 101 is fixedly connected to four stirring blades 103, and the stirring blades 103 are located in the collecting area 1a.

It also includes a box door 104; the box door 104 is arranged at the collection area 1a.

It also includes a pump case 201, a pipeline 202, a suction pipe 1 203, a suction pipe 204 and a suction pipe 3 205; the box body 1 is fixedly connected to the pump case 201; the suction part of the pump case 201 is connected to the pipeline 202; the pipeline 202 is connected to the suction pipe 1 203, and the suction pipe 1 203 is connected to the inside of the box body 1; the pipeline 202 is connected to the suction pipe 2 204, and the suction pipe 2 204 is connected to the inside of the box body 1; the pipeline 202 is connected to the suction pipe 3 205, and the suction pipe 3 205 is connected to the inside of the box body 1.

Suction pipe 1 203 is located below the crushing roller 4, suction pipe 204 is located near the discharge port 1 8, and suction pipe 3 205 is located near the box door 104. The generated dust can be fully extracted to prevent it from escaping to the outside and being inhaled by surrounding workers, affecting their physical safety.

A filter bag 206 is also included; the output portion of the pump case 201 is connected to the filter bag 206 .

The working steps of the above embodiment are as follows: in the specific work, the required crushed stone raw materials are manually put into the box body 1 from the feed port 2, and the driving box 3 is controlled to drive the crushing roller 4 to rotate, so as to crush the put-in crushed stone raw materials. After crushing, the crushed stone falls on the screen 6 below, and the crushed stone is screened by the screen 6, and the larger crushed stone is screened out after crushing, and the larger crushed stone is screened by the inclined screen 6, and the screened larger crushed stone can roll down and be discharged from the discharge port 8, and the subsequent staff collects it and puts it into the box body 1 for further crushing until it is processed into machine-made sand; and the machine-made sand is collected in the collection area 1a;

However, a large amount of dust will be generated during crushing and screening. Therefore, during the process of machine-made sand processing, the pump housing 201 is controlled to suck the inside of the housing 1 through the pipeline 202, the suction pipe 1 203, the suction pipe 204 and the suction pipe 3 205 in sequence to extract the generated dust, and the sucked gas is passed into the filter bag 206 to filter the extracted dust through the filter bag 206 to avoid the generated dust being discharged to the outside, which will affect the hygiene and health of the workers.
