[0036] Example 2:
[0037] Specifically, the water outlet pipe 17 is provided in two sets and fixedly connected to both sides of the second connecting rod 15, and the actuating plate 16 is fixedly provided on the lower side of the second connecting rod 15. The actuating plate 16 is provided in two sets and symmetrically arranged.
[0038] In this embodiment, the water outlet pipe 17 is made of PVC, with 6 spray holes evenly distributed on each side of the pipe, and the spray direction is 45° downward with respect to the horizontal; the toggle plate 16 is made of natural rubber, and the bottom edge is arc-shaped.

[0047] In use, firstly, the washing sand is conveyed to the inside of the water tank body 11 by the on-site conveyor rotation. Then, the drive motor 12 is started, driving the reciprocating screw 13 to rotate. Simultaneously, one end of the second connecting rod 15 slides on the water tank body 11, causing the actuating plate 16 to reciprocate and move the washing sand inside the water tank body 11. At the same time, the installed water pump (not shown) is started to draw water from the water tank (not shown), which is then sprayed out onto the water tank body 11 through the water outlet pipe 17. Inside, the washed sand is rinsed, and the water outlet pipe 17 is driven by the second connecting rod 15 to rinse it back and forth. By pulling the baffle 19 out of the water tank body 11, the washed sand and water in the water tank body 11 can fall onto the screen 24. By starting the drive cylinder 21, the connecting cylinder 23 is pulled back and forth, causing the connecting cylinder 23 to swing back and forth on the guide slide rod 25, so that the screen 24 can screen the washed sand and collect it through the collection device set up on site.
[0048] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means.
