[0023] In this embodiment, the chassis 1 can be reinforced by dividing the four reinforcing steel frames 12 into a group and installing them on both sides of the chassis 1 at a 45-degree angle. By dividing the four motors 7 into two groups, one group rotates clockwise and the other group rotates counterclockwise, the vibrating member 8 can be vibrated when the motor 7 is running. By installing the plate 9 at an angle and the height of the water leakage port 10 being lower than the highest point of the sieve plate 9, water can be separated from sand when the chassis 1 vibrates, and the water can flow into the inside of the leakage pipe 11 through the leakage port 10. By locating the bottom of the leakage pipe 11 inside the water storage tank 21 and the leakage pipe 11 being The interior of 11 is interconnected with the interior of the chassis 1 through the water leakage port 10, so that the water flowing out of the water leakage port 10 can flow into the interior of the water storage tank 21 through the water leakage pipe 11.

By opening the sieve holes 14 with a diameter of one centimeter in a rectangular array, larger impurities in the sand can be screened out when the chassis 1 vibrates, and the impurities inside the sieve box 13 can be cleaned by pulling out the cleaning frame 15 through the handle 16.
[0024] Specifically, there are four reinforcing steel frames 12, and two reinforcing steel frames 12 are grouped together and installed at a forty-five degree angle on both sides of the chassis 1. By dividing the four reinforcing steel frames 12 into a group and installing them at a forty-five degree angle on both sides of the chassis 1, the chassis 1 can be reinforced.
[0025] Specifically, there are four motors 7, which are divided into two groups, one group rotates clockwise and the other group rotates counterclockwise. By dividing the four motors 7 into two groups, one group rotates clockwise and the other group rotates counterclockwise, the vibrating member 8 can be vibrated when the motors 7 are operating.
[0026] Specifically, the sieve plate 9 is installed at an angle, and the height of the leakage port 10 is lower than the highest point of the sieve plate 9. By installing the sieve plate 9 at an angle, and the height of the leakage port 10 is lower than the highest point of the sieve plate 9, water and sand can be separated when the chassis 1 vibrates, and water can flow into the inside of the leakage pipe 11 through the leakage port 10.
[0027] Specifically, the bottom of the leakage pipe 11 is located inside the water tank 21, and the interior of the leakage pipe 11 is communicated with the interior of the chassis 1 through the leakage port 10. By locating the bottom of the leakage pipe 11 inside the water tank 21 and communicating with the interior of the chassis 1 through the leakage port 10, the water flowing out of the leakage port 10 can flow into the interior of the water tank 21 through the leakage pipe 11.

[0029] Specifically, the diameter of the sieve hole 14 is one centimeter, and the sieve hole 14 is opened in a rectangular array. By opening the sieve hole 14 with a diameter of one centimeter in a rectangular array, larger impurities in the sand can be screened out when the chassis 1 vibrates, and the cleaning frame 15 can be pulled out by the handle 16 to clean the impurities inside the sieve box 13.
[0030] The working principle or use process of the utility model: When the utility model is used, the sand pumping machine 4 is first started to extract the sand that needs to be screened through the sand pumping pipe 5, and then the sand is pumped into the interior of the chassis 1 through the sand outlet pipe 6, and then the motor 7 is started to rotate the vibrating member 8 to vibrate the chassis 1. The sand and water inside the chassis 1 are separated by vibration. When the water accumulates to overflow the leakage hole 10, the water will flow through the leakage hole 10 into the leakage pipe 11 and into the interior of the water storage tank 21. The sand inside the chassis 1 will gradually fall through the sieve plate 9 because the vibration direction is oblique. The sand enters the interior of the screening box 13, and then the sand will be screened out by the sieve holes 14 opened inside the screening box 13, while the larger debris will be left inside the screening box 13. When the debris inside the screening box 13 accumulates to a certain extent, the cleaning frame 15 can be opened by the handle 16, and the cleaning frame 15 will sweep away the debris inside the screening box 13. When the chassis 1 vibrates, the vibration damping member 18 will reduce the impact of the vibration on the support column 17 to prevent damage to the device.
