A telescopic limiting rod 518 for controlling its movement track is fixedly connected to the bottom of one side of the arc-shaped frame 521.

[0028] The end of the linkage shaft 510 away from the rotating plate 59 is slidably connected to the slide groove 512 opened in the middle of the swing rod 511, which can not only realize the relative movement between the linkage shaft 510 and the swing rod 511, but also ensure a stable connection between the two, avoiding loosening or detachment during operation.

[0029] The inner wall of the pulley A513 is fixedly connected with a spring A, and the other end of the spring A is fixedly connected to the pawl 523.

[0030] When in use, first start the motor to drive the transmission shaft 58 to drive the rotating plate 59 to rotate, and then the linkage shaft 510 at the upper end of the rotating plate 59 will rotate accordingly. At the same time, since the linkage shaft 510 is slidably connected to the inside of the slide groove 512, when the rotating plate 59 continues to rotate, the linkage shaft 510 will make a circular motion in the slide groove 512 and push the swing rod 511 to swing back and forth around the rotating rod 52 as the axis, thereby driving the rotating rod 52 and the top mounting plate 53 to swing left and right synchronously, so that the sprayer 33 and the suction cover 43 on the mounting plate 53 can be adjusted in the horizontal direction, thereby expanding the dust removal operation range; At the same time, when the transmission shaft 58 rotates, it will drive the ratchet 522 fixed on the outer wall to rotate synchronously. Under the action of the spring A on the inner wall of the pulley A513, the pawl 523 always contacts the ratchet 522. When the ratchet 522 rotates counterclockwise, the pawl 523 will be embedded in the tooth groove of the ratchet 522 and drive the pulley A513 to rotate. Then, the transmission action of the transmission belt 514 will cause the pulley B515 to rotate synchronously, thereby driving the reciprocating screw 517 on the upper end of the pulley B515 to rotate. When the reciprocating screw 517 rotates, The connecting rod connected to the outer wall thread will be driven to reciprocate up and down along its axial direction, and the connecting rod will drive the arc frame 521 at both ends to move synchronously. The slider 520 in the arc frame 521 will pull the sprayer 33 and the suction cover 43 to swing up and down with the movable shaft 55 as the axis through the connecting rod 519. Combined with the previous horizontal swing, the sprayer 33 and the suction cover 43 can achieve multi-angle dust removal operation in a three-dimensional space, ensuring that dust at different heights and positions can be effectively treated. When the ratchet 522 rotates clockwise, the pawl 523 will slide on the back of the teeth of the ratchet 522. At this time, the pulley A513 will not rotate accordingly, thereby ensuring that the reciprocating screw 517 only reciprocates in a specific direction, avoiding motion conflicts that affect the stability of the device.

[0031] Example 2, please refer to Figures 1-8On the basis of Example 1, the inner side of the purification tank 45 is equipped with a cleaning and filtering assembly 6, which includes a fixed plate 61. A moving rod 62 is slidably penetrated on the upper side of the fixed plate 61. The two ends of the moving rod 62 are respectively fixedly connected to an arc block 63 and a connecting block 65. A rotating shaft 67 is rotatably penetrated on one side of the purification tank 45. A moving cylinder 66 is fixedly connected to the inner side of the connecting block 65. A scraper 68 is fixedly connected to the outer wall of the rotating shaft 67. A spiral groove 69 is opened on the outer wall of the rotating shaft 67. A sliding shaft 610 is fixedly connected to the inner wall of the moving cylinder 66. A filter plate 611 is provided on the inner wall of the purification tank 45.

[0032] The movable cylinder 66 is movably sleeved on the outside of the rotating shaft 67, and the sliding shaft 610 is slidably connected to the inside of the spiral groove 69, so that relative movement can occur between the two. At the same time, the sliding shaft 610 is embedded in the inside of the spiral groove 69 through the form of sliding connection, thereby achieving dynamic cooperation with the spiral groove 69. The outer wall of the fixed plate 61 is fixedly connected to the spring B64, and the other end of the spring B64 is fixedly connected to the arc block 63. During use, when the mounting plate 53 swings, it pushes the arc block 63 to move, which in turn drives the moving rod 62 to slide along the direction through which the fixed plate 61 passes. The connecting block 65 at the other end of the moving rod 62 then drives the moving cylinder 66 to slide outside the rotating shaft 67. Because the sliding shaft 610 on the inner wall of the moving cylinder 66 is slidably connected to the spiral groove 69 on the outer wall of the rotating shaft 67, when the moving cylinder 66 moves axially along the rotating shaft 67, the sliding shaft 610 slides within the spiral groove 69 and drives the rotating shaft 67 to rotate, thereby driving the scraper 68 on the outer wall of the rotating shaft 67 to rotate synchronously. During the rotation process, the scraper 68 contacts the surface of the filter plate 611 on the inner wall of the purification tank 45, scraping and cleaning the dust and impurities attached to the filter plate 611 to prevent the filter plate 611 from being blocked and affecting the purification effect; When the mounting plate 53 swings in the opposite direction and no longer squeezes the arc block 63, the spring B64 on the outer wall of the fixed plate 61 will push the arc block 63 to reset, driving the moving rod 62, the connecting block 65 and the moving cylinder 66 to move in the opposite direction, causing the sliding shaft 610 to slide in the opposite direction in the spiral groove 69, and then driving the rotating shaft 67 and the scraper 68 to rotate in the opposite direction, realizing reciprocating cleaning of the filter plate 611, ensuring that the filter assembly continues to work efficiently.

[0033] Example 3, please refer to Figures 1-8On the basis of Example 1, the inner and outer sides of the water tank 31 are equipped with a mixing assembly 7, which includes a stirring shaft 71, which is rotatably connected to the inner wall of the water tank 31, and a stirring rod 72 is fixedly connected to the outer wall of the stirring shaft 71. One end of the stirring shaft 71 passes through the water tank 31 and is fixedly connected to a gear 73. A rack 74 is engaged at the bottom of the gear 73, and a rectangular frame 76 is fixedly connected to the outer wall of the rack 74. The bottom of the slider 520 is fixedly connected to a fixed shaft 77, and the top of the water tank 31 is fixedly connected to a chemical treatment agent box 79.

[0034] The bottom of one side of the curved frame 521 is provided with an arcuate groove 78. A fixed shaft 77 slides within the groove 78 and the interior of the rectangular frame 76. The fixed shaft 77 not only slides flexibly within the groove 78 but also extends into the interior of the rectangular frame 76, performing the same sliding connection there. A slide rail 75 is fixedly connected to the outer wall of the water tank 31. The rack 74 slides along the outer wall of the slide rail 75, ensuring a stable connection between the rack 74 and the slide rail 75.

[0035] During use, treatment agent is first added to the interior of the water tank 31 through the chemical treatment agent tank 79. Then, as the slider 520 moves along the arc-shaped frame 521, the fixed shaft 77 at its bottom slides along the arc-shaped groove 78 at the bottom of the arc-shaped frame 521. Since the fixed shaft 77 is also installed inside the rectangular frame 76, its sliding will drive the rectangular frame 76 to move back and forth in the horizontal direction. The rectangular frame 76 then pulls the rack 74 to slide back and forth on the slide rail 75. The rack 74 and the gear 73 are meshed with each other. The sliding of the rack 74 drives the gear 73 to rotate forward and backward. The gear 73 drives the stirring shaft 71 to rotate synchronously. The stirring rod 72 on the outer wall of the stirring shaft 71 rotates inside the water tank 31, fully mixing the water in the water tank 31 with the treatment agent added by the chemical treatment agent tank 79, forming a uniform dust removal spray, thereby improving the subsequent spray dust removal effect.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
