[0029] Combined with Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 7 : An opening and closing device 6 capable of adjusting the size of the air inlet and the air volume flow rate is provided at one end of the direction adjustment component 3 away from the anti-blocking and wind dispersion device 2, a retracting and expanding bracket 5 for controlling the retraction and expansion of the opening and closing device 6 is provided between the opening and closing device 6 and the direction adjustment component 3, a detachable dust collecting bag 7 is sleeved between the opening and closing device 6 and the anti-blocking and wind dispersion device 2, the opening and closing device 6 comprises a cross-axis frame 601, the four ends of the cross-axis frame 601 are rotatably connected with support rods 602, the two sides of the end of the support rod 602 away from the cross-axis frame 601 are rotatably connected with a first fan-shaped wind plate 603 and a second fan-shaped wind plate 604, the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 between two adjacent support rods 602 are hinged, the hinge of the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 is rotatably connected with a U-shaped rotating frame 605, and the ends of the four support rods 602 are detachably connected with the detachable dust collecting bag 7; The retracting bracket 5 comprises a first main rod 501 fixedly connected to a cross-axis frame 601, a sliding sleeve 502 is slidably connected to the first main rod 501, and the sliding sleeve 502 is provided with four shaft frames 504 corresponding to the U-shaped rotating frame 605 at the bottom end near the cross-axis frame 601, and a rotating rod 505 is provided between the shaft frames 504 and the U-shaped rotating frame 605; The direction adjustment assembly 3 includes a fixing sleeve 310 fixedly connected to the first main rod 501, first extension frames 311 are provided on both sides of the bottom of the fixing sleeve 310, a second extension frame 503 corresponding to the first extension frame 311 is provided at one end of the sliding sleeve 502 close to the fixing sleeve 310, an extension frame adjustment assembly 4 is provided between the first extension frame 311 and the second extension frame 503, and the extension frame adjustment assembly 4 includes a threaded rod 402 located between the first extension frame 311 and the second extension frame 503, one end of the threaded rod 402 is rotatably connected to the first extension frame 311, and the other end is threadedly connected to the second extension frame 503, and a first driving motor 401 for controlling the rotation of the threaded rod 402 is provided on the first extension frame 311; Through the above structure, the first drive motor 401 is started to drive the threaded rod 402 to rotate, thereby controlling the second extension frame 503 to drive the sliding sleeve 502 to slide on the first main rod 501. When the sliding sleeve 502 is close to the cross-axis frame 601, the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 are in a fully opened state. At this time, the air inlet area is the smallest. When the second extension frame 503 drives the sliding sleeve 502 to slide on the first main rod 501 in the direction of the direction adjustment component 3, the axis frame 504 pulls the U-shaped rotating frame 605 toward the second extension frame 503 through the rotating rod 505, so that the two adjacent first fan-shaped wind plates 603 and the second fan-shaped wind plates 604 are bent toward the second extension frame 503. At this time, the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 are in a fully opened state. 04 and the detachable dust bag 7, and a gap appears between the bend of the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 and the detachable dust bag 7, and dust enters the dust bag through the gap. When the second extension frame 503 continues to drive the sliding sleeve 502 to slide on the first main rod 501 in the direction of the direction adjustment component 3, the two adjacent first fan-shaped wind plates 603 and the second fan-shaped wind plates 604 drive the support rod 602 to bend. At this time, the dust collecting cross-sectional area of ​​the detachable dust bag 7 is reduced, and the gap between the bend of the first fan-shaped wind plate 603 and the second fan-shaped wind plate 604 and the detachable dust bag 7 is increased. During this process, the air inlet area remains basically the same, so that the negative pressure in the detachable dust bag 7 is maintained within a relatively stable range, thereby preventing dust from overflowing. The detachable dust bag 7 is open at both ends and tightened in the middle, and a steel ring support frame is provided in the middle. This is a prior art and is not described here.

[0030] In the specific implementation of the present invention, when the unloading vehicle is dumping, the second drive motor 305 is started to drive the worm 304 to rotate, thereby driving the worm wheel 306 to rotate, and the worm wheel 306 is fixedly connected to the wheel frame 307, and is rotationally connected to the stand 309, so that the fixed sleeve 310 can rotate with the connecting shaft of the worm wheel 306 and the stand 309 as the axis, thereby adjusting the angle of the fixed sleeve 310, and starting the third drive motor 308 to drive the stand 309 to rotate with the output shaft of the third drive motor 308 as the axis, thereby adjusting the angle of the fixed sleeve 310, so that the air inlet of the detachable dust bag 7 is aligned with the position of the unloading pile; The dust collecting fan 1 is started to collect dust synchronously. When the second extension frame 503 drives the sliding sleeve 502 to slide on the first main rod 501 in the direction of the direction adjustment component 3, the shaft frame 504 pulls the U-shaped rotating frame 605 to move toward the second extension frame 503 through the rotating rod 505, so that the two adjacent first fan-shaped air plates 603 and the second fan-shaped air plates 604 are bent toward the second extension frame 503. At this time, a gap appears between the bending part of the first fan-shaped air plates 603 and the second fan-shaped air plates 604 and the detachable dust collecting bag 7, and dust enters the dust collecting bag 7 through the gap. When the second extension frame 503 continues to drive the sliding sleeve 502 to slide on the first main rod 501 toward the direction adjustment component 3, the two adjacent first fan-shaped air plates 603 and second fan-shaped air plates 604 drive the support rod 602 to bend. At this time, the air inlet area of ​​the detachable dust bag 7 is reduced, and the gap between the bending part of the first fan-shaped air plate 603 and the second fan-shaped air plate 604 and the detachable dust bag 7 is increased. During the process, the air inlet area is basically kept consistent, so that the negative pressure in the detachable dust bag 7 is kept within a relatively stable range, thereby preventing dust from overflowing. The curved wind slot 2022 in the return air cover 202 forms a wind dispersing channel, so that the air volume at the filter holes of the annular filter plate 2023 is uniform, and dust is not easy to approach the circular filter plate 204, thereby causing damage to the dust removal fan 1. The fourth drive motor 209 is started, and the fourth drive motor 209 drives the gear 208 to rotate. Through the cooperation between the gear 208 and the inner gear ring 203, the first cleaning brush 212 rotates and revolves at the same time, thereby ensuring that the circular filter plate 204 always remains unobstructed; During the revolution of the fourth drive motor 209, the second cleaning brush 211 is driven to rotate in the curved wind slot 2022 via the curved connecting rod 210, so that the second cleaning brush 211 cleans the annular filter plate 2023. The vibration generated by the fourth drive motor 209 during the operation is conducive to the cleaning of the annular filter plate 2023 by the second cleaning brush 211, thereby ensuring that the annular filter plate 2023 always remains unobstructed.

[0031] The present invention and its implementation methods are described above, and such description is not restrictive, and the actual structure is not limited thereto. In general, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can creatively design a structure and implementation method similar to the technical solution, which should fall within the protection scope of the present invention.
