[0032] Further: The water injection mechanism 6 includes a nozzle 61 arranged above the third screen body fixing frame 25, and the water injection mechanism 6 also includes a water pipe 62 and a solenoid valve 63. One end of the water pipe 62 is used to connect to the nozzle 61, and the other end of the water pipe 62 is connected to the solenoid valve 63, and the solenoid valve 63 is connected to the water pump.

[0033] Further: The drainage assembly 7 includes a funnel 71 disposed below the third screen body fixing frame 25 , and a drainage pipe 72 is disposed on the funnel 71 .

[0034] In this embodiment, the base frame 41 is installed on the inner frame 11 of the oscillator 1, and then the soil sample is poured into the filter screen 3 of the third sieve body fixing frame 25, the solenoid valve 63 of the water injection mechanism 6 is connected to the water source through a water pump, the solenoid valve 63 is opened and the water is led to the nozzle 61 through the water pipe 62 by the water pump, and finally the water is injected into the filter screen 3 of the third sieve body fixing frame 25 through the nozzle 61; At this time, turn on the oscillator 1 switch and set the speed, 500-1000 rpm for fine soil samples, 100-300 rpm for coarse soil samples, the soil sample with small particles in the filter screen 3 is separated by the third filter screen 3, the second filter screen 3 and the first filter screen 3 in turn under the action of dense water flow impact and reciprocating oscillation, and the water pump and the oscillator 1 are turned off when the water flowing through the drain pipe 72 in the drain assembly 7 becomes clear, and the soil particles of different particle sizes are separated; After the soil screening is completed, the driving rod 52 in the retraction control assembly 5 is rotated. Since the driving rod 52 is threadedly connected to the linkage frame 51, and the limit ring 53 on the linkage frame 51 is slidably connected to the guide rod 221 on the right vertical frame 22, and the guide member 511 is an arc panel, the arc panel at the bottom contacts the roller 54 on the first screen body fixing frame 23 and the roller 54 on the second screen body fixing frame 24, and the arc panel at the top contacts the roller 54 on the second screen body fixing frame 24 and the roller 54 on the third screen body fixing frame 25. Therefore, when the driving rod 52 is rotated, the linkage frame 51 will be driven to approach the right vertical frame 22. In the process of the linkage frame 51 approaching, the arc panel at the bottom will press the first screen body fixing frame 23 and the roller 54 on the second screen body fixing frame 24. The roller 54 on the second sieve body fixing frame 24 makes the second sieve body fixing frame 24 away from the first sieve body fixing frame 23, and the arc panel at the top will press the roller 54 on the third sieve body fixing frame 25, so that the third sieve body fixing frame 25 is away from the second sieve body fixing frame 24. At this time, the distance between the first sieve body fixing frame 23 and the second sieve body fixing frame 24 is consistent with the distance between the second sieve body fixing frame 24 and the third sieve body fixing frame 25. The staff can turn the container for receiving the soil sample particles upside down above the first sieve body fixing frame 23, the second sieve body fixing frame 24 and the third sieve body fixing frame 25, and the container for receiving the soil sample particles can be connected to the corresponding filter screen 3 by snap-fit ​​or threaded connection; Next, the three filter screens 3 need to be turned over so that the soil sample particles inside them are transferred to the receiving container. The staff twists the connecting rod 42 in the turning drive assembly 4. Since the connecting rod 42 passes through the column 411 and is rotatably connected thereto, and one end of the connecting rod 42 is fixedly connected to the left stand 21, when the connecting rod 42 rotates, the first screen body fixing frame 23, the second screen body fixing frame 24 and the third screen body fixing frame 25 are driven to turn over through the left stand 21. When the turning over is completed, the soil particles in the three filter screens 3 all fall into the corresponding receiving containers, and then the water sprayed by the nozzle 61 is used to make all the particles in the filter screens 3 fall into the corresponding receiving containers to avoid a certain degree of sticking, and the soil particles in the three receiving containers are dried for inspection. Finally, the three filter screens 3 are restored to their states, and the linkage rod 42 in the flip drive assembly 4 is twisted to drive the first screen body fixing frame 23, the second screen body fixing frame 24 and the third screen body fixing frame 25 to flip and reset through the left vertical frame 21, and then the driving rod 52 is rotated to make the linkage frame 51 move away from the right vertical frame 22 and drive the guide member 511 which is the arc panel. At this time, the expansion support of the corresponding arc panel will be lost between the first screen body fixing frame 23 and the second screen body fixing frame 24, and the expansion support of the corresponding arc panel will be lost between the second screen body fixing frame 24 and the third screen body fixing frame 25. Since the first screen body fixing frame 23 is fixedly connected to the left vertical frame 21 and the right vertical frame 22, the second screen body fixing frame 24 and the third screen body fixing frame 25 above it after flipping will fall again to form a stacked state, and the next batch of separation processing can be continued at this time.
