Description

Technical Field

[0001] The utility model relates to the technical field of soil detection and processing, in particular to a sample crushing device for soil detection. Background Art

[0002] Soil testing refers to determining the environmental quality (or degree of pollution) and its changing trend by determining the representative values ​​of factors that affect soil environmental quality. What we usually call soil testing refers to soil environmental monitoring, which generally includes on-site sampling, sample preparation, analysis methods, result characterization, data statistics, quality evaluation and other technical contents. During soil testing, the soil to be tested needs to be crushed, so sample crushing equipment for soil testing is needed.

[0003] Patent No. CN202020201370.2 discloses a sample crushing device for soil detection, including a support foot, a crushing box is fixedly connected to the top of the support foot, a feed hopper is fixedly connected to the middle of the top of the crushing box, a discharge pipe is fixedly connected to the middle of the bottom of the crushing box, a motor is fixedly installed in the middle of one side of the crushing box, a rotating shaft is fixedly connected to the middle of one side of the motor, a stirring blade is fixedly connected to the outside of the rotating shaft, a crushing hole is opened in the middle of the stirring blade, a leakage plate is fixedly connected to the middle of the inner bottom wall of the crushing box, and a leakage hole is opened on the upper surface of the leakage plate. The utility model can improve the fluidity of the soil by setting the motor, the rotating shaft and the stirring blade, thereby improving the crushing efficiency of the soil, and can prevent the soil particles from affecting the detection results by setting the crushing hole and the leakage hole, thereby improving the reliability of the device.

[0004] At present, the crushing effect of the sample crushing equipment for soil testing is relatively good, but the crushing equipment usually uses crushing teeth to crush the sample soil. When the crushing teeth are used for a certain period of time, they will be damaged. The connection between the existing crushing teeth and the motor is mostly an integral fixed structure to ensure the stability of the crushing. If one of the crushing teeth is damaged, it will affect the overall use effect and shorten the service life of the crushing equipment. It is not convenient to disassemble and replace the crushing teeth. After the crushing equipment crushes the soil sample, it is not convenient to quickly take out the soil sample, which requires a lot of manual labor and affects the soil detection efficiency. Therefore, we propose a new type of sample crushing equipment for soil testing. Utility Model Content
