[0030] Working principle: When the device is installed and used for dust prevention of material boxes related to putty powder production, the device is connected to the lifting equipment through a cable, and then the device is hung on the material box through the lifting equipment, and the staff fine-tunes the position of the device on the material box so that the base frame 103 completely covers the feed port of the material box; after placement, the two gate plates 201 can be separated by the operation of the hydraulic rod 204, and the air in the collecting barrel 301 is continuously sucked through the operation of the pump 401; when the crushed putty powder raw material is injected into the material box from the opening above the feed rack 101, it will pass through the feed rack 101, the middle rack 102, and the base rack 103 from high to low, and fall into the material box. During the falling process of the putty powder raw material, the collecting barrel 301 with a negative pressure inside will continuously suck the air on the feed rack 101 through the dust collecting frame 303 and the material guide pipe 304. The dust of putty powder raw materials floating at the square opening can be prevented, thereby effectively limiting the range of dust dispersing outside the device; when the material box is filled with materials, the hydraulic rod 204 can be made to work again to reset the gate plate 201, so as to prevent the putty powder raw materials in the material box from floating out of the device. When it is observed through the window 104 that there is no more dust floating above the putty powder raw materials accumulated in the material box, the device can be lifted off the material box and the material box can be sealed; when the device has been running for a long time and there is a large amount of putty powder raw materials in the collecting barrel 301, the staff can push the push-pull rod 306 to separate the collecting barrel 301 from the sealing cover 308, and the unloading piece 307 pushes the putty powder raw materials out of the collecting barrel 301. When the staff no longer touches the push-pull rod 306, under the action of the spring 311, the guide rod 310 will drive the push-pull rod 306 and the unloading piece 307 to reset through the sealing cover 308.
