[0036] Combine Figures 1 to 4 As shown, according to a specific embodiment of the present utility model, a belt conveyor tail dust removal system is provided.

[0037] Specifically, if Figure 1 、 Figure 2As shown, the belt conveyor tail dust removal system includes: a tail airtight cover 10, which is arranged at the tail part 100 of the machine and is used to seal the dust at the tail of the machine, and a vent 11 is provided on the tail airtight cover 10; a connecting component 20, one end of the connecting component 20 is connected to the vent 11; a pulse bag filter 30, an air inlet 31 of the pulse bag filter 30 is connected to the vent 11; an air suction part 40, the air suction part 40 is connected to the air outlet 32 ​​of the pulse bag filter 30, and the air suction part 40 is used to generate an airflow so that the dust at the tail part 100 of the machine flows into the pulse bag filter 30 through the connecting component 20, and the pulse bag filter 30 is used to blow and collect dust.

[0038] In this embodiment, by setting up a pulse bag filter 30 and utilizing pulse spraying technology, the dust generated at the tail of the belt conveyor can be efficiently captured and removed, significantly improving the dust removal efficiency.

[0045] like Figure 3 As shown, the belt conveyor tail dust removal system also includes: a positioning mechanism 50, the positioning mechanism 50 is fixed on the tail enclosure 10, and is located on both sides of the vent 11, the positioning mechanism 50 has a locking state for fixing the dust hood 21 on the tail enclosure 10, and the positioning mechanism 50 has an unlocking state for detaching the dust hood 21 from the tail enclosure 10.

[0046] By switching between locked and unlocked states, the positioning mechanism 50 enables quick installation and removal of the dust hood 21, significantly improving the convenience of equipment maintenance and reducing production downtime caused by equipment maintenance. Furthermore, the positioning mechanism 50 ensures a stable connection between the dust hood 21 and the tail enclosure 10, enhancing the overall stability and reliability of the system.

[0047] like Figure 3 As shown, the dust hood 21 includes: a dust hood body 211, which is arranged on the tail airtight cover 10; a raised structure 212, which is arranged on both sides of the dust hood body 211 and extends along the length direction of the dust hood body 211.

At the same time, the positioning mechanism 50 ensures a stable connection between the dust hood 21 and the tail airtight cover 10, enhancing the overall stability and reliability of the system.

[0048] Furthermore, the positioning mechanism 50 includes: a limit block 51, the limit block 51 has a limit space with an opening on one side; a linkage part 52, the linkage part 52 is arranged on both sides of the limit block 51, and the linkage part 52 is operated to move, so that the linkage part 52 has a stop protrusion structure 212 so that the protrusion structure 212 is located in a locked state within the limit space, and the linkage part 52 has a release protrusion structure 212 so that the protrusion structure 212 is out of the unlocked state of the limit space.

[0050] The combined design of the limiting space of the limiting block 51 and the elastic member 522, L-shaped frame 521, and connecting rod 523 of the linkage part 52 enables the rapid locking and unlocking of the dust hood 21, improving the usability and flexibility of the device. In the locked state, the dust hood 21 can be kept stable, avoiding displacement caused by vibration or airflow impact, thereby ensuring the dust removal effect; in the unlocked state, the dust hood 21 can be quickly disassembled for cleaning or replacement. The use of the elastic member 522 allows the connecting rod 523 to remain close to each other in the initial state, forming a locked state; in the compressed state, the connecting rod 523 moves away from each other, unlocking the dust hood 21 for easy disassembly. This design not only simplifies the operation process, but also ensures the stability of the locked state through the elastic force of the elastic member.

[0051] Furthermore, the connecting rod 523 is provided with a groove 5231, and the L-shaped frame 521 is provided with a mating rod 524.
