Description

Technical Field

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

[0002] Soil environmental monitoring refers to an important measure to understand the status of soil environmental quality. It aims to prevent and control the hazards of soil pollution and conducts dynamic analysis and measurement of the degree and development trend of soil pollution. It includes surveys on the current status of soil environmental quality, surveys on regional soil environmental background values, investigations on soil pollution accidents and dynamic observations of polluted soil. Currently, most soil tests are conducted in laboratories, and the collected soil needs to be crushed to facilitate observation of the soil.

[0003] A Chinese patent discloses a laboratory soil detection crushing device (CN216284558U), including a base and a cover plate, the top of the base is fixedly connected with a processing frame, and the top of the processing frame is fixedly connected with a rubber pad. The utility model relates to the technical field of soil detection devices. The laboratory soil detection crushing device, by setting a driving frame at the bottom of the cover plate, drives the motor to drive the second rotating rod to rotate, thereby driving the grinding disc to rotate and drive the processing hammers on both sides to move up and down reciprocatingly, so as to achieve the effect of rotating and beating the soil blocks inside the processing frame. At the same time, the rotation of the grinding disc can also grind small soil blocks, so as to achieve the effect of quickly breaking the soil blocks, avoid the situation that the soil blocks are not completely broken due to manual crushing, and increase the efficiency of soil detection experiments. Most of the crushing devices currently used have only the crushing function. During the crushing process, the soil may adhere to the inner wall of the crushing device, which not only easily reduces the crushing quality, but also is not convenient for later collection. Therefore, a laboratory soil detection crushing device is provided. Utility Model Content
