[0002] With the development of society, the amount of waste generated is also increasing day by day. The unreasonable discharge and random discarding of waste products and wastewater have caused great pollution and damage to the land. Therefore, soil testing is becoming more and more important. Common soil testing refers to soil environmental monitoring, which generally includes technical contents such as on-site sampling, sample preparation and laboratory analysis.

[0003] Soil samples collected on site need to be air-dried, ground, and sieved before they can be used for experimental testing. However, some types of soil (such as clay) are very hard after air-drying. The current way to handle this kind of soil in the laboratory is to first break up the soil blocks with a wooden hammer, and then use a wooden roller to grind the soil blocks into fine particles and sieve them. This processing method is labor-intensive and has low grinding efficiency, which brings great inconvenience to the staff.

[0040] The soil sample to be ground is spread in the soil grinding box 100, and the motor 110 is started. The power of the motor 110 is transmitted to the driven pulley 120 through the V-belt, and then the driven pulley 120 drives the first sprocket 130 to rotate together.

The slider 210 and the slide rail 200 are slidably matched. When the roller 151 moves from the tight side of the chain 150 to the loose side, the roller 151 can slide along the length direction of the slide groove. Therefore, with the operation of the chain 150, the roller 151 can drive the slider 210 to move back and forth on the slide rail 200, so that the soil roller 340 can repeatedly grind the soil sample in the soil grinding box 100. The ground soil sample can be screened and stored for experimental detection.
