[0024] Specifically combined Figure 2 The blowing mechanism 3 comprises a fan 31 and a fan box 32, the fan 31 is arranged in the fan box 32 in a regular manner, the fan box 32 is arranged on the support 1, the fan box 32 is a rectangular box, the top surface is provided with a detachable screen 33, and the four side vertical surfaces are solid surfaces, so as to ensure that the fan blows upward and does not leak from the side. One or more rows of fans can be arranged at equal intervals in the fan box 32, and 3-6 fans are arranged at equal intervals in each row.

[0025] Further referring to Figures 3-4The impeller power module 21 includes a fan 211 and a motor 212. A support rib 11 is provided on the top of the bracket 1, and the fan 211 is mounted on the support rib 11. A protective cover 2114 is provided around the fan 211, also mounted on the support rib 11. The impeller head 22 is connected to the air inlet 2111 of the fan 211 via a dust collection pipe 24. The dust collection tank 23 is connected to the air outlet 2112 of the fan 211 via a dust outlet pipe 25. The motor 212 is connected to the impeller 2113 inside the fan 211 to drive the impeller 2113 to rotate. The impeller head 22 is trapezoidal funnel-shaped, with one small opening connected to the dust collection pipe 24 and the larger opening aligned with the lower conveyor line. When the blower 211 is started, the suction head 22 draws air to draw impurities into the blower 211, and discharges the impurities from the air outlet 2112 along the dust discharge pipe 25 into the dust collection tank 23 for storage. When the dust collection tank 23 is full, it can be replaced and taken away for unified processing.

[0026] Combined with reference Figure 3 , Figure 5 The dust collection trough 23 is provided with a dust inlet 231, which is movably connected to the dust outlet pipe 25, and a connector 26 is provided at the connection point.

When replacing the dust collection tank 23, pressing the connector 26 releases the pressure between the limiting block 263 and the pre-reserved slot 262, allowing the dust inlet 231 to be removed from the dust outlet pipe 25. This enables quick disassembly and replacement of the dust collection tank 23, improving the equipment's operational convenience and maintenance efficiency.
