When the pump body 1 64 is turned on, the clean water in the connecting box 60 enters the annular tube 68 through the Y-shaped tube 66 and the connecting tube 65, and is sprayed from the nozzle 69 to clean the beef. The pump body 2 600 is turned on, so that the sewage flows out through the conduit 601. The sewage passes through the surface of the guide plate 72 and changes its flow direction, so that one of the two groups of filter plates 63 is filtered. The filtered sewage passes through the pump body 1 64 again, enters the annular tube 68, and is sprayed from the nozzle 69 to achieve recycling.

[0026] The interference hole 742 is set to an arc shape, which can drive the circular plate 741 to rotate when the interference rod 743 moves. The limiting groove 747 is set to a hemispherical shape, and the diameter of the limiting groove 747 is smaller than the diameter of the limiting bead 746. When the linkage plate 7402 is not limited, the rotating rod 71 is rotated, and the limiting bead 746 can enter the limiting groove 747 in turn to interfere. A motor 3 is fixed on the top of the cleaning box 1, and the output shaft of the motor 3 passes through the cleaning box 1. A stirring rod 5 is fixed on the surface of the output shaft of the motor 3. A bottom plate 4 is fixed on the inner wall of the cleaning box 1. A water leakage hole is opened on the surface of the bottom plate 4. The motor 3 and the pump body 64 are opened. When the motor 3 is started, the stirring rod 5 is driven to rotate, which can roll the beef and improve the cleaning efficiency. The water leakage hole can discharge sewage. Two groups of filter plates 63 are provided, and the two groups of filter plates 63 are symmetrically arranged with the center line of the connecting box 60 as the symmetry axis, which can be used alternately and convenient for replacement.

[0027] When it is necessary to clean the beef, open the box door 2, place the beef on the surface of the bottom plate 4, close the box door 2, and inject clean water into the connection box 60. At this time, start the motor 3 and the first pump body 64. When the motor 3 starts, it drives the stirring rod 5 to rotate, which can tumble the beef and improve the cleaning efficiency. When the first pump body 64 is turned on, the clean water in the connection box 60 enters the annular pipe 68 through the Y-shaped pipe 66 and the connecting pipe 65, and sprays out from the nozzle 69 to clean the beef. The sewage falls through the water leakage holes of the bottom plate 4. At the same time, the operator can turn on the second pump body 600, so that the sewage flows out through the conduit 601. The sewage passes through the surface of the guide plate 72 and changes its flow direction, so that one of the two filter plates 63 is filtered. The filtered sewage passes through the first pump body 64 again, enters the annular pipe 68, and sprays out from the nozzle 69 to realize recycling. When the filter plate 63 is blocked and needs to be replaced and cleaned after a long time of use, at this time, the operator pulls down the T-shaped plate 7400, so that the linkage plate 7402 disengages from the card slot 7403. At this time, turn the knob 73, which drives the rotating rod 71 to rotate, so as to change the orientation of the guide plate 72, and then change the flow direction of the sewage, so that the other filter plate 63 can perform the filtering work. At the same time, when the rotating rod 71 rotates, the inner wall of the limiting groove 747 abuts against the surface of the limiting bead 746, so that the limiting bead 746 drives the sliding rod 744 to move away from the rotating rod 71, and the first spring 745 is compressed. The sliding rod 744 drives the abutting rod 743 to move synchronously. The abutting rod 743 abuts against the abutting hole 742, causing the circular plate 741 to rotate. The rotation of the circular plate 741 drives the linkage plate 7402 to move synchronously. When the rotating rod 71 continues to rotate, the limiting bead 746 can sequentially enter the limiting groove 747 and abut against the inner wall of the limiting groove 747. At the same time, the first spring 745 is released, and the sliding rod 744 drives the limiting bead 746 to enter the limiting groove 747, so that the circular plate 741 and the linkage plate 7402 return to their positions. When the guide plate 72 is adjusted, the T-shaped plate 7400 can be released, and the second spring 749 drives the T-shaped plate 7400 to return to its position. At this time, the T-shaped plate 7400 enters the card slot 7403 to limit the linkage plate 7402 and the circular plate 741. The through hole 7401 enables the linkage plate 7402 to move normally, so that the sliding rod 744 cannot continue to move, and the limiting bead 746 is limited by the limiting groove 747, which can prevent the guide plate 72 from rotating automatically due to the impact of the water flow. At this time, the operator can take out the filter plate 63 that needs to be replaced through the L-shaped plate 62. When installing, placing the L-shaped plate 62 on the top of the connection box 60 can make it stable, so that there is no need to stop the cleaning equipment, improving the work efficiency.

[0028] Generally speaking, the above has described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
