[0002] In construction projects, soil is indispensable for dams, road bridges, houses, etc. Geotechnical tests are used to study the physical and mechanical properties of soil through experimental methods, so as to provide reliable parameters for engineering design and construction. It is an important means for engineering quality supervision and supervision, and also the basis for correctly evaluating engineering geological conditions, carrying out quality improvement, engineering quality assessment, engineering safety evaluation and identification, and project acceptance. The soil particle size analysis test is a common geotechnical test method for measuring the particle size distribution of soil, which requires separating and weighing soil particles of different particle sizes in the soil. For sandy gravel soil containing clay particles, it is necessary to wash the soil sample through a sieve with water again and again to separate soil particles of different particle sizes in the soil sample. At present, the washing and screening in the particle size analysis test are mostly carried out manually. At the same time, when washing, the soil sample is continuously washed with water flow, which causes a certain degree of waste of water resources. Summary of the Invention

[0025] When using the present invention, according to the precision required for screening soil particles, an appropriate number of screening pools 2 are selected. After connecting several screening pools 2 through the insertion rods 6, they are inserted into the water storage pool 1. The adjustment motor 16 is started, and the adjustment motor 16 drives the adjustment screw rod 15 to rotate. The adjustment screw rod 15 drives the sliding block 14 to move up and down through the thread.

During the rotation of the rotating mechanism 12, the push rod 20 is driven to rotate. During the rotation of the push rod 20, the cleaning pool 19 is driven to rotate.

[0026] Compared with the prior art, the beneficial effects of the present specific embodiment are as follows: 1. Several screening pools 2 are stacked on the water storage pool 1. While performing water washing and screening, the washed sewage can pass through the screening pool 2 and enter the water storage pool 1, so that it can be reused again, reducing the waste of water resources, and the circulating water can be ensured to be clear water through the filter screen 17, improving the water washing effect; 2. Several spray heads 11 arranged at equal angles in the screening tank 2 can be rotated by the drive of the rotating mechanism 12, so that the clear water sprayed by the spray heads 11 can be stirred during the cleaning process, thereby improving the screening effect; 3. Several screening tanks 2 are connected by inserting rods 6, and the conveying mechanism 8 can be spliced according to requirements, so that the number of screening tanks 2 can be selected, thereby improving the screening speed.
