With the cooperation of the end 13, spring 14, elastic ball 16 and other structures, the fluid stress generated by the instantaneous flow of water can be released.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Multiple friction grooves are provided on the surface of the end 13. The multiple friction grooves are arranged in a ring array on the end 13. The friction grooves can improve the sliding friction effect of the end 13.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5A guide mechanism 9 is provided on both the rotating disk 7 and the separating tank 1. The guide mechanism 9 includes a fixing ring 90. The fixing ring 90 is fixedly sleeved on the outer side of the rotating disk 7. A fixing ring 91 is fixedly sleeved on the outer side of the rotating disk 7 and below the fixing ring 90.

[0023] The specific implementation process of this utility model is as follows: When in use, concrete can be input into the rotating disk 7 through the setting of the conveying pipe 4. Under the action of the clean water pipe 5, high-pressure water can be sprayed into the rotating disk 7. When the motor 6 drives the output shaft to rotate, it can drive the rotating disk 7 to rotate, thereby driving the separation net 8 to rotate, thereby driving the concrete to rotate. With the flushing action of the high-pressure water, the concrete can be effectively separated from sand and gravel. When water is instantly transported inside the clear water pipe 5, the high-pressure water can be guided by the flow guide pipe 10, so that the high-pressure water impacts the end 13, causing the telescopic frame 12 to slide along the inner wall of the fixed block 11, causing the spring 14 to form and drive the telescopic frame 12 to move, so that the telescopic frame 12 squeezes the elastic ball 16. Under the deformation of the spring 14 and the elastic ball 16, the fluid stress generated by the water can be released instantly, avoiding the problem of impact damage to the pipeline structure. When the rotating disk 7 rotates, it drives the first fixed ring 90 and the second fixed ring 91 to rotate, causing the limiting block 96 to slide along the surfaces of the rotating disk 7, the first fixed ring 90, and the second fixed ring 91, thereby limiting the rotation of the rotating disk 7 and preventing centrifugal vibration. This can drive the rotating disk 98 to rotate, and with the threaded connection, it can drive the screw barrel 95 to move, thereby driving the slide plate 94 to slide along the inner wall of the slide groove 93, thus ensuring the stable movement of the screw barrel 95, and finally driving the limiting block 96 to move, so as to ensure the fitting effect of the limiting block 96.
