Description

Technical Field

[0001] The utility model relates to a soil block hardness detection device, belonging to the field of soil detection. Background Technique

[0002] Soil hardness detection is one of the items in soil detection. When detecting the hardness of a soil block, the soil block needs to be placed between the anchor cable dynamometer and the pressing plate installed at the movable end of the driving member. The driving member can be a hydraulic cylinder, an electric push rod, etc. When controlling the driving member to extend, the pressing plate moves downward and squeezes the soil block. Thus, the extrusion force received by the soil block is transferred to the anchor cable dynamometer, and the hardness of the soil block can be measured through the reading on the anchor cable dynamometer. However, the shape of the soil block is generally irregular. When the soil block is placed between the pressing plate and the anchor cable dynamometer, the soil block will move out between the anchor cable dynamometer and the pressing plate due to uneven force, affecting the detection of the soil block. Therefore, it is necessary to design a soil block hardness detection device that can prevent the displacement of soil blocks with irregular shapes during the extrusion process. Content of the Utility Model
