The rack 36 moves forward and backward continuously, which will cause the extrusion rod 326 to intermittently squeeze the moving plate 321. When the extrusion rod 326 does not squeeze the moving plate 321, the moving plate 321 will be reset and move forward by the elastic force of the spring 322, which will start the spring pump 319, causing the spring pump 319 to exhaust gas and eject gas through the exhaust pipe 324. The exhaust pipe 324 is located above the conveyor belt 31, so that the dust and debris left on the conveyor belt 31 due to transmission can be blown away from the conveyor belt 31. Cleaning the dust and debris on the conveyor belt 31 can ensure that the working environment during the sand making process remains clean, which helps to reduce the impact of dust on equipment and operators and improve the comfort and safety of the working environment.
