[0021] The reciprocating mechanism 6 includes a first support plate 601 fixedly connected to the upper end of the grit chamber main body 1. A first guide groove 602 is provided inside the first support plate 601. The outer structure of the first guide groove 602 is wavy, and the cooperation mode between the first guide groove 602 and the first guide rod 603 is clearance fit, so that the first guide rod 603 can swing when moving along the track of the first guide groove 602. A first guide rod 603 is provided inside the first guide groove 602. A rack 604 is fixedly connected to the upper end of the first guide rod 603. The connection mode between the rack 604 and the second support plate 605 is transverse sliding connection, and the thickness of the rack 604 is greater than the thickness of the gear 611, so that the rack 604 can swing transversely on the upper end of the second support plate 605. A second support plate 605 is fixedly connected to the upper end of the scraper 5. A third support plate 606 is fixedly connected to the upper end of the second support plate 605. A first hole 607 is provided inside the third support plate 606. A second guide groove 608 is communicated with the inner wall of the first hole 607. A second guide rod 609 is provided inside the second guide groove 608. A rotating rod 610 is provided inside the first hole 607. The outer structure of the rotating rod 610 is cylindrical, and the outer side surface of the rotating rod 610 fits with the inner side surface of the first hole 607, so that the rotating rod 610 will not rotate when rotating inside the first hole 607. The connection mode between the rotating rod 610 and the second guide rod 609 is fixed connection. The rack 604 is meshed with a gear 611 above it. The connection mode between the gear 611 and the rotating rod 610 is key connection. The outer structures at both ends of the second guide groove 608 are arc-shaped, and the middle end of the second guide groove 608 is "V"-shaped, so that the second guide rod 609 will not move horizontally when moving inside the arc groove of the second guide groove 608, and the second guide rod 609 will move horizontally when moving inside the "V" shape of the second guide groove 608.

[0022] The swinging mechanism 7 includes a fourth support plate 701 fixedly connected to the end of the second support plate 605 away from the gear 611. A second hole 702 is provided inside the fourth support plate 701. A sliding block 703 is provided inside the second hole 702. A telescopic rod 704 is fixedly connected to the upper end of the sliding block 703. The connection mode between the telescopic rod 704 and the rotating rod 610 is hinge connection. A nozzle 705 is fixedly connected to the lower end of the sliding block 703. A water pump 706 is fixedly connected to the upper end of the first support plate 601. The water pump 706 and the nozzle 705 are communicated through a water pipe 707. The outer structure of the sliding block 703 is spherical, and the outer side surface of the sliding block 703 fits with the inner side surface of the second hole 702, so that the sliding block 703 can move inside the second hole 702 without shaking.

[0023] When cleaning is required, start the motor 2 to drive the threaded rod 3 to rotate, so that the first sliding plate 4 and the scraper 5 move horizontally to clean the inner side of the grit chamber main body 1, drive the second support plate 605 and the rack 604 to move horizontally, so that the first guide rod 603 moves horizontally. Since the first guide rod 603 is nested inside the first guide groove 602, and the outer structure of the first guide groove 602 is wavy, the first guide rod 603 and the rack 604 perform reciprocating motions, so that the gear 611 performs reciprocating rotations, and then the rotating rod 610 rotates, driving the telescopic rod 704, the sliding block 703 and the nozzle 705 to rotate, driving the second guide rod 609 fixedly connected thereto to rotate. Since the two ends of the second guide groove 608 are arc-shaped and the middle end of the second guide groove 608 is "V"-shaped, when the second guide rod 609 moves to the inside of the "V"-shaped groove, it will swing left and right, pulling the telescopic rod 704, the sliding block 703 and the nozzle 705 to swing, expanding the spraying range of the nozzle 705, and the grit chamber main body 1 can be cleaned from multiple angles, making the cleaning cleaner.
