By starting the dust suction pump 7, the dust in the crushing box 1 can be sucked and discharged into the dust removal box 4, and then the dust can be treated by the dust removal assembly arranged in the dust removal box 4, so as to avoid the dust from spreading outward.

[0023] Please refer to Figures 2-3 The baffle 9 is fixedly installed in the left opening of the dust removal box 4, the rubber sheets 10 are glued and bonded on the bottom side of the baffle 9, and the rubber sheets 10 are closely arranged. The rubber sheets 10 can be used for closing and shielding at the left opening of the dust removal box 4, so as to avoid the dust from spreading outward as much as possible.

[0024] Please refer to Figures 2-3The door sealing assembly 6 includes a rotating shaft 11 rotatably connected to the top of the feed hopper 2. A fixed cylinder 12 is fixedly installed on the outside of the rotating shaft 11. A sealing plate 13 is fixedly installed in the middle of the fixed cylinder 12. The sealing plate 13 has a protrusion and a recess on opposite sides, and the protrusion is stuck in the recess. A fixed shell 14 is fixedly installed on the outside of the feed hopper 2 at both ends of the rotating shaft 11. The end of the rotating shaft 11 is rotatably connected to the fixed shell 14. A spiral spring 15 is fixedly installed between the inner wall of the fixed shell 14 and the outer side of the rotating shaft 11. The spiral spring 15 supports and positions the rotating shaft 11 through its own elasticity, so that the sealing plates 13 on both sides are horizontally abutting in the initial state, thereby sealing and covering the top opening of the feed hopper 2 to prevent the internal dust from spreading outward.

[0025] Please see Figure 4 The dust removal assembly includes a water inlet pipe 16 fixedly installed on the top of the dust removal box 4. A support pipe 17 is fixedly installed at the bottom end of the water inlet pipe 16. The support pipe 17 is U-shaped, and a water pump is connected to the other end of the water inlet pipe 16.

The water will then be sprayed downward through the atomizing nozzle 19 on the bottom side of the frame pipe 18 to suppress the dust flying inside and prevent the dust from spreading outward.

[0028] In summary, the dust removal device in the production of this sand roller supports and positions the rotating shaft 11 through the elastic force of the spiral spring 15, so that the sealing plates 13 on both sides are horizontally abutting in the initial state, thereby sealing and covering the top opening of the feed hopper 2. Therefore, the opening can be automatically reset and sealed and covered at the stone pouring port, thus minimizing the spread of internal dust to the outside.

[0029] By starting the dust pump 7, the dust in the pulverizing box 1 can be pumped into the dust removal box 4. Then, by starting the water pump, water can be drained along the water inlet pipe 16, and water mist will be sprayed downward through the atomizing nozzle 19 on the bottom side of the frame pipe 18, thereby suppressing the dust flying inside and preventing the dust from spreading outward.
