Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a centrifugal analysis device for soil detection. Background Art

[0002] Soil testing refers to determining the environmental quality and its changing trends by measuring the representative values of factors affecting soil environmental quality. Soil monitoring usually refers to soil environmental monitoring. When monitoring soil, soil samples are usually placed in test tubes, which are centrifuged by rotating the test tubes, and then the centrifuged soil material is monitored. When the test tubes are centrifuged, they are usually placed in the grooves on the rotating rods and then rotated. However, if the test tubes are not fixed, they may be thrown out during rotation.

[0003] A search for the above-mentioned problem revealed that among the currently disclosed prior art, there is a soil testing centrifugal analysis device proposed in publication number CN218782074U. This device places a test tube in a mounting hole of a mounting plate. Then, by turning a handle, a gear engages, thereby rotating a screw, moving a limit block forward, and then fitting the limit block against the test tube, which is then fixed. However, since the test tube is mostly made of glass, if the force is not properly controlled when moving the limit block, the limit block may move forward excessively, thereby breaking the test tube, thereby affecting subsequent centrifugal testing. Utility Model Content
