Description

Technical Field

[0003] The soil sampling device with publication number CN219757779U is provided with an electric telescopic rod, a lifting plate, a motor, a sampling structure and a connecting sleeve. The main body of the sampling structure includes a drill bit and a sampling tube spliced ​​by two symmetrical semicircular tubes. The top of the sampling tube is fixedly connected to the connecting sleeve by a first bolt, and the connecting sleeve is fixedly connected to the motor drive shaft. When the motor drives the sampling tube to rotate, the electric telescopic rod can drive the motor and the sampling tube to descend, and the drill bit is used to crush the rock in the soil, so that the sampler can sample various harder geological soils, thereby improving practicality. However, when unloading, it is necessary to first unscrew the first bolt on the top of the sampling tube to separate the sampling tube from the connecting sleeve, and then unscrew the second bolt fixing the sampling tube and the drill bit to separate the drill bit from the sampling tube. At this time, the sampling tube can be divided into two semicircular tubes, and then the cylindrical soil inside can be taken out. The sampling tube needs to be manually disassembled to collect the soil, which affects the work efficiency of the staff. When multiple sampling is performed, it cannot meet the production needs.
