[0001] The invention relates to the technical field of conveying and dust removal, and in particular to an airflow dust removal structure at the edge of a conveyor. Background Art

[0002] Conveyors are needed in the process of loading and unloading goods, especially belt conveyors, which are the most widely used in conveying scenarios. Belt conveyors are mainly composed of frames, conveyor belts, rollers, drums, tensioning devices, transmission devices, etc. They can form a material conveying process from the initial feeding point to the final unloading point on a certain conveyor line. It can convey both bulk materials and piece items.

[0003] When transporting goods, especially loose goods, a certain amount of dust will be generated when placing the goods on the conveyor, which will pollute the transportation environment over time. At the same time, the generated dust will remain on the surface of the conveyor belt, affecting the subsequent transportation of goods. The dust in the transportation process needs to be cleaned manually, which is time-consuming and labor-intensive. With the development of technology, a cleaning mechanism is set on the conveyor belt, such as a rotating brush in contact with the surface of the conveyor belt, which can clean the surface of the conveyor belt.

The roller 103 is located below the conveyor belt 102 to support and limit the conveyor belt 102. A driving mechanism is also installed on the frame 101 to drive the drum 104 to rotate, drive the conveyor belt 102 to make a rotary motion, and transport the material. The structure includes a baffle 1, which is in contact with the conveyor belt 102 of the conveyor, and also includes a protective cover 2, an airflow generating component and a dust collecting component. Compared with the existing The existing conveyor uses a manual or rotating brush 403 to clean the conveyor belt 102.

At the same time, the fan 203 and the vacuum pump 204 generate airflow, so that the dust is collected in the bag 302. The reciprocating screw 401 is driven by the conveyor to rotate, so that the movable frame 402 and the brush 403 move back and forth inside the protective cover 2 to clean the inner wall of the protective cover 2 to prevent dust from clogging the air intake hole. At the same time, the crankshaft 701 is driven by the conveyor to rotate, so that the piston 703 moves back and forth to hit the knocking block 705, which drives the protective cover 2 to vibrate, and assists in shaking off the dust on the surface of the protective cover 2, thereby improving the dust removal effect.
