Soil is put into the screening bin 1 through the feed port 3, so that the soil falls onto the top sieve plate 12, and then the vibration is driven by the vibration pump 8 to make the soil fall onto the middle sieve plate 11, and then fall onto the bottom sieve plate 10, so that the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 all have soil particles of different sizes. During the screening process, the detection personnel can prepare for the next step of the process.

[0022] In a preferred embodiment, the bottom sieve plate 10 has no holes at the bottom, and the holes on the middle sieve plate 11 are smaller than the holes on the top sieve plate 12, so that the top sieve plate 12 can screen out small soil particles and leave large soil particles on the top sieve plate 12, and the middle sieve plate 11 can screen out fine soil particles and leave medium soil particles on the middle sieve plate 11. At this time, the bottom sieve plate 10 retains fine soil particles.

[0023] In a preferred embodiment, the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 are all movably connected to the mounting bracket 9, and the ends of the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 away from the mounting bracket 9 are fixedly equipped with a connecting block 13, and the inner wall of the connecting block 13 is movably sleeved with a connecting bracket 14, and the end of the connecting bracket 14 away from the connecting block 13 is movably sleeved with a lifting rod 15. By pulling the lifting rod 15, the lifting rod 15 moves upward to drive the connecting bracket 14 to move. At this time, the angle of the connecting bracket 14 changes, and the three connecting brackets 14 respectively drive the angles of the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 to change. Due to the change in angle, the soil particles can roll, thereby improving the rationality of the device.

[0024] In a preferred embodiment, the inner wall of the analysis chamber 2 is provided with a fixed plate 16, the bottom of the fixed plate 16 is installed with a mounting plate 18, the inner wall of the mounting plate 18 is fixedly equipped with a slide groove 19, and a soil storage drawer 17 is provided on the left side of the slide groove 19. The soil storage drawer 17 is located above the fixed plate 16. The soil rolls on the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12, and the soil particles slide into the soil storage drawer 17 through the slide groove 19, so that the soil particles can be stored in the soil storage drawer 17. By pulling out the soil storage drawer 17, the soil particles can be subjected to the next step of detection, thereby improving the rationality of the device.

[0025] In a preferred embodiment, three fixed plates 16, slide grooves 19 and soil storage drawers 17 are provided respectively, and each fixed plate 16, slide groove 19 and soil storage drawer 17 corresponds to the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12, and detection needles 20 are fixedly installed under the three fixed plates 16. When soil particles enter the soil storage drawer 17, soil particles of different coarseness and fineness will contact the corresponding detection needles 20. Soil particles of different coarseness and fineness are detected by the detection needles 20, thereby improving the rationality of the device.

[0026] In a preferred embodiment, a mounting groove 21 is provided on the outer edge of the analysis chamber 2, and a display 22 is fixedly mounted on the inner wall of the mounting groove 21. There are three mounting grooves 21 and three displays 22, and the display 22 is connected to the detection needle 20 through an electric wire. The data detected by the three detection needles 20 are transmitted to the corresponding display 22, and the data of soil of different coarseness and fineness can be observed through the display 22.

[0027] Working principle: when in use, soil is put into the screening bin 1 through the feed port 3, the soil falls onto the top sieve plate 12, and then the vibration is driven by the vibration pump 8, the soil falls onto the middle sieve plate 11, and then falls onto the bottom sieve plate 10. At this time, soil particles of different sizes remain on the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12. Then the lifting rod 15 is pulled upward to drive the three connecting brackets 14 to move. The angles of the three connecting brackets 14 change, and the three connecting brackets 14 respectively drive the angles of the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 to change. At this time, the soil particles on the bottom sieve plate 10, the middle sieve plate 11 and the top sieve plate 12 slide onto the soil storage drawer 17 through the slide 19 respectively. At this time, soil particles of different coarseness and fineness contact the detection needle 20 respectively, and then the detection needle 20 transmits the data to the corresponding display 22, and the user can observe the data of soil particles of different coarseness and fineness through the display 22.
