[0026] During operation, the first cover plate 2 can prevent the dust generated during the grinding process from flying out when grinding concrete, thereby reducing environmental pollution. The first handle 1 and the third handle 27 make it convenient for the staff to open the cover plate, control the switch of the fan 10 through the controller 9, and collect the ground concrete powder through the receiving box 13. The second handle 14 makes it convenient for the staff to carry the receiving box 13.
[0027] Further, such as Figure 2 and Figure 3 As shown, a third filter plate 21 is fixedly connected to the lower inner part of the grinding tank body 5, a grinding cone 17 is penetrated and rotatably connected to the middle of the top of the third filter plate 21, a dust box 22 is fixedly connected to the middle of the bottom of the third filter plate 21, a spiral feeding rod 23 is penetrated and rotatably connected to the middle of the bottom of the dust box 22, a dual-rotor motor 24 is fixedly connected to the middle of the inner bottom of the dust box 22, and the two output ends of the dual-rotor motor 24 are respectively penetrated and fixedly connected to the grinding cone 17 and the spiral feeding rod 23, and a second filter plate 20 is fixedly connected to the middle of the inner wall of the grinding tank body 5. The grinding cone 17 passes through the second filter plate 20, the first filter plate 19 is fixedly connected to the upper inner wall of the grinding tank body 5, and the grinding cone 17 passes through the first filter plate 19, the inner wall of the grinding tank body 5 is fixedly connected with evenly distributed first grinding columns 16, the outer wall of the grinding cone 17 is fixedly connected with evenly distributed second grinding columns 18, and the second grinding columns 18 correspond to the first grinding columns 16, the bottom of the first fixed plate 3 is fixedly connected to the collecting hopper 11, the bottom of the collecting hopper 11 is fixedly connected to the discharge pipe 12, and the discharge pipe 12 corresponds to the spiral feeding rod 23.
[0028] During operation, the space inside the grinding tank body 5 is divided into three spaces by the first filter plate 19, the second filter plate 20 and the third filter plate 21. Under the action of the three filter plates, the accumulation of raw materials is avoided, which causes a large operating load on the equipment. The first grinding column 16 and the second grinding column 18 are respectively provided on the inner wall of the grinding tank body 5 and the grinding cone 17, which reduces the grinding time and improves the grinding efficiency of the concrete. Under the action of the spiral feeding rod 23, the ground concrete powder is transported to the outside at a uniform speed, and with the cooperation of the discharge pipe 12, the splashing of concrete powder is reduced.
[0029] Further, such as Figure 4 As shown, a dust removal assembly is provided between the lower parts of the support columns 6, and the dust removal assembly includes a dust collection head 8, which passes through and is fixedly connected to the support columns 6. A dust collection box 26 is passed through and fixedly connected to the middle part of the rear side of the dust collection head 8 through a pipe, and a partition net 29 is fixedly connected to the lower part of the interior of the dust collection box 26. A dust collection bag 28 is provided on the upper side of the partition net 29, and the dust collection bag 28 corresponds to the dust collection head 8, and a fan 10 is passed through and fixedly connected to the lower part of the rear side of the dust collection box 26.
[0030] During operation, the dust removal component first turns on the fan 10. Under the action of the fan 10, the air inside the dust box 26 is discharged, and then a negative pressure is formed near the inner opening of the dust collector head 8, which sucks in the splashed concrete dust and enters the dust collecting bag 28 through the dust collector head 8 and is collected. When the grinding of concrete is stopped, the second cover 25 is opened through the third handle 27, and then the dust collecting bag 28 is taken out, and the concrete powder filtered inside the dust collecting bag 28 is taken out, thereby reducing environmental pollution and reducing the loss of raw materials.
[0031] Working principle: When concrete needs to be ground, first open the first cover plate 2 through the first handle 1, then put the raw materials in through the opening on the upper part of the grinding tank body 5, then turn on the dual-rotor motor 24 to drive the grinding cone 17 to rotate, and at the same time drive the spiral feeding rod 23 to rotate, and the second grinding column 18 rotates with the grinding cone 17. Under the action of the rotating grinding cone 17 and the second grinding column 18, and in cooperation with the first grinding column 16, large pieces of raw materials are crushed, and the crushed raw materials into small pieces fall through the opening on the first filter plate 19 onto the second filter plate 20. At this time, the gap between the grinding cone 17, the second grinding column 18 and the grinding tank body 5 becomes smaller, so that the raw materials are continuously filtered. The concrete powder is further crushed into smaller raw materials and falls onto the third filter plate 21 through the openings on the second filter plate 20. At this time, the gaps between the grinding cone 17, the second grinding column 18 and the grinding tank body 5 become smaller again. After continuing to grind to a suitable particle size, the concrete powder falls into the collecting hopper 11 through the openings on the third filter plate 21, moves downward along the slope of the inner wall of the collecting hopper 11, and is transported to the outside through the discharge pipe 12 under the action of the rotating spiral feeding rod 23. The concrete powder falls into the receiving box 13 and is collected. The dust generated during the concrete collection process is then removed by the dust removal component. After the collection is completed, the receiving box 13 is finally pulled out by the second handle 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
