[0002] The rocks on the Earth's surface are gradually broken down into loose mineral particles of varying sizes through weathering. Soil is formed and evolved under the combined effects of various soil-forming factors, such as parent material, climate, organisms, topography, and time. Soil composition is very complex, generally consisting of solid, liquid, and gaseous phases, including minerals, organic matter from the decomposition of plant and animal remains, water, and air. Soil environmental monitoring refers to determining environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we usually refer to it, generally includes technical aspects such as sampling site selection, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation.

[0003] In related technologies, soil testing often involves drying the soil and then pre-treating it by crushing the dried, clumped soil, then sieving, sampling, and finally testing. However, this method can easily crush debris such as stones and tree roots that have fallen into the soil along with the clumps, resulting in inaccurate soil test data.

[0004] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

The side of the receiving plate 2 near the collection box is open to the outside.

[0022] A sieve plate 3 is provided above the receiving plate 2. A driving device for causing the sieve plate 3 to shake is provided between the receiving plate 2 and the sieve plate 3. The driving device includes a fixing block 5 fixedly connected to the upper end face of the receiving plate 2. A protruding rod 6 is provided on both sides of the fixing block 5, with one end of the protruding rod 6 rotatably connected to it. A cavity is opened in the fixing block 5. A motor 1 for driving the protruding rod 6 to rotate is installed in the cavity. The motor 1 is a servo motor. The output shaft of the motor 1 is connected to one end of the protruding rod 6. The other end of the protruding rod 6 is rotatably connected to a driving rod 7. The other end of the driving rod 7 is rotatably connected to the side wall of the sieve plate 3.

[0023] Several protrusions 8 are fixedly connected to the side wall of the sieve plate 3, and several protrusions 9 corresponding to the positions of protrusions 8 are fixedly connected to the side wall of the receiving plate 2. A limiting plate 10 is provided between protrusions 8 and protrusions 9, and the two ends of the limiting plate 10 are rotatably connected to protrusions 8 and protrusions 9 respectively.

[0024] A baffle plate 4 is fixedly connected around the screen plate 3. A pressure roller 15 is provided on the upper end face of the screen plate 3. The pressure roller 15 is in contact with the upper end face of the screen plate 3. A moving device for driving the pressure roller 15 is provided on the inner wall of the baffle plate 4. The moving device includes a groove 11 provided on the inner wall of the baffle plate 4. A lead screw 12 is rotatably connected to the inner wall of the groove 11. A motor 13 for driving the lead screw 12 to rotate is installed on the side wall of the baffle plate 4. A nut seat 14 is sleeved on the lead screw 12. The pressure roller 15 is rotatably connected to the nut seat 14.

[0025] A limiting block 16 is fixedly connected to the side wall of the nut seat 14. A limiting groove 17 is provided on the inner wall of the groove 11 for the limiting block 16 to be inserted and moved.

[0026] Working principle: When soil pretreatment is required, the soil is poured onto the sieve plate 3, which is a fine-mesh sieve plate. After the soil is poured in, the protruding rods 6 on both sides are driven to rotate synchronously by motor one. The protruding rods 6 drive the drive rod 7 connected to them to push and pull, which causes the sieve plate 3 to shake. At this time, the limiting plate 10 will rotate with the shaking of the sieve plate 3, so that the sieve plate 3 and the receiving plate 2 can remain parallel, making the screening process more stable. At the same time, the lead screw 12 is driven by motor two 13 to rotate in both directions. The lead screw 12 drives the nut seat 14 to move back and forth. 14 drives the pressure roller 15 to reciprocate and press the soil clods on the screen plate 3. Since the soil clods are loose materials, they can be dispersed into loose soil particles after being pressed. However, stones and branches are hard materials, and branches and roots are mostly long strips and lumps, which are difficult to break down by pressing. After being crushed, they cannot become fine particles like soil. During the screening process, the soil can fall through the screen plate 3 onto the receiving plate 2 and then be collected in the collection box along the inclined surface of the receiving plate 2. Stones and roots will remain on the screen plate 3, realizing the separation of impurities and making the subsequent test results of the soil more accurate.

All technical solutions falling within the scope of this utility model's concept are protected.
