DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-Figure 4As shown, the embodiment of the utility model proposes a blowing pipe structure of a bag dust collector, including a dust collecting cylinder 1, a dust collecting bag 2, a quick assembly and disassembly assembly and a blowing pipe dust collecting assembly: an air intake blowing pipe 3 is arranged on the top of the dust collecting cylinder 1, and an air pump can be connected to the upper end of the air intake blowing pipe 3 to quickly blow air into the dust collecting bag 2 through the air intake blowing pipe 3, an exhaust pipe 4 is arranged on the lower end of the side wall of the dust collecting cylinder 1, and a supporting base is fixedly connected to the bottom of the dust collecting cylinder 1; the quick assembly and disassembly assembly includes an upper mounting fixedly connected to the lower end of the outer wall of the air intake blowing pipe 3 Block 5, a lower mounting block 6 is fixedly connected at the port of the dust bag 2, a plug-in plate 7 is fixedly connected to the side wall of the lower mounting block 6, a plug-in protrusion is arranged on the upper end of the plug-in plate 7, a clamping component is arranged on the upper mounting block 5, and the clamping component includes two sliding rods 11 fixedly connected to the side wall of the upper mounting block 5, and the ends of the two sliding rods 11 away from the upper mounting block 5 are fixedly connected to the abutment plate 12, and the two sliding rods 11 are slidably connected to the clamping plate 13, and a compression spring 14 is fixedly connected between the clamping plate 13 and the abutment plate 12, and the abutment plate 1 2 is provided with a through hole in the middle, and a pull rod 16 is fixedly connected to the middle of the card plate 13, and the pull rod 16 matches the through hole; by pushing the lower mounting block 6 upward, the plug-in board 7 is driven to move upward, so that the plug-in board 7 first contacts and squeezes the card plate 13, so that the card plate 13 slides outward on the sliding rod 11, and at the same time, the compression spring 14 starts to compress and accumulate force. When the plug-in protrusion at the upper end of the plug-in board 7 is located at the upper end of the card plate 13, the compression spring 14 elastically pushes the card plate 13 to move inward, thereby making the card plate 13 close to the plug-in protrusion. The plate 7 is automatically snap-fitted and fixed, so that the upper mounting block 5 and the lower mounting block 6 can be quickly fixed. When the dust bag 2 and the air intake blowing pipe 3 are disassembled, the snap-fit ​​plate 13 can be moved by pulling the pull rod 16, so that the snap-fit ​​plate 13 moves outward on the sliding rod 11, and then the snap-fitting of the plug-in plate 7 can be directly released, and the dust bag 2 and the air intake blowing pipe 3 can be disassembled, so that the air intake blowing pipe 3 and the dust bag 2 can be quickly loaded and unloaded, and the dust bag 2 can be replaced and maintained conveniently.

[0018] like Figure 1 , Figure 2 and Figure 4As shown, the blow pipe dust removal assembly includes two limit blocks 8 fixedly connected to the inner wall of the air intake blow pipe 3, and guide rods 9 are slidably connected to the two limit blocks 8. The ends of the two guide rods 9 located outside the air intake blow pipe 3 are fixedly connected to traction rods 15, and the ends of the guide rods 9 located inside the air intake blow pipe 3 are fixedly connected to an annular scraper 10, which fits the inner wall of the air intake blow pipe 3, and the outer ring side of the annular scraper 10 is arranged in an inclined structure; the two guide rods 9 are driven to move downward by pulling the traction rod 15, so that the two guide rods 9 drive the annular scraper 10 in the air intake blow pipe 3 to move downward, and the dust layer attached to the inner wall of the air intake blow pipe 3 can be scraped and cleaned by the downward movement of the annular scraper 10 relative to the inner wall of the air intake blow pipe 3, thereby ensuring the blowing rate of the air intake blow pipe 3 and the dust removal efficiency of the dust removal cylinder 1.

[0019] When in use, during the installation process of the air intake blowing pipe 3 and the dust bag 2, firstly, the lower mounting block 6 is matched with the upper mounting block 5, and the lower mounting block 6 is pushed upward, so that the plug-in plate 7 first contacts and squeezes the clamping plate 13, so that the clamping plate 13 slides outward on the sliding rod 11, and at the same time, the compression spring 14 starts to compress and accumulate force. When the plug-in protrusion at the upper end of the plug-in plate 7 is located at the upper end of the clamping plate 13, the compression spring 14 elastically pushes the clamping plate 13 to move inward, so that the clamping plate 13 automatically clamps and fixes the plug-in plate 7, thereby facilitating the rapid fixation of the upper mounting block 5 and the lower mounting block 6. When the dust bag 2 and the air intake blowing pipe 3 are disassembled, the clamping plate 13 can be driven to move by pulling the pull rod 16 The movement causes the clamping plate 13 to move outward on the sliding rod 11, and then the clamping fixation of the plug-in plate 7 can be directly released, and the dust bag 2 and the air intake blowing pipe 3 can be disassembled, so that the air intake blowing pipe 3 and the dust bag 2 can be quickly loaded and unloaded, and the dust bag 2 can be replaced and maintained conveniently; after the dust bag 2 is disassembled, the two guide rods 9 can be driven downward by pulling the traction rod 15, so that the two guide rods 9 drive the annular scraper 10 in the air intake blowing pipe 3 to move downward, and the annular scraper 10 can be moved downward relative to the inner wall of the air intake blowing pipe 3 to scrape and clean the dust layer attached to the inner wall of the air intake blowing pipe 3, thereby ensuring the blowing rate of the air intake blowing pipe 3 and the dust removal efficiency of the dust removal cylinder 1.
