Soil sampling equipment for geological survey

Abstract

The invention discloses soil sampling equipment for geological survey. A sampling box, a storing box and a storage box are mounted on an upper end face of a vibration-absorption base; a motor is fixedin a groove of a U-shaped seat of the sampling box; an output shaft of the motor is connected with a sampling barrel; the vibration-absorption base is provided with a penetrating hole capable of penetrating through the sampling barrel; sliding blocks are fixed at two sides of the U-shaped seat respectively; one sliding block is connected with a thread rod through a thread; a tapered gear is fixedon the thread rod; the tapered gear is engaged with a main tapered gear on a rotary shaft; a crank handle is fixed at one end of the rotary shaft; the storing box is provided with a pulling drawer for storing a sample; a storage battery for supplying a power supply to the motor is arranged in the storage box; an L-shaped push rod is fixed at the top of the storage box. The soil sampling equipmentdisclosed by the invention has the advantages of simple structure and convenience for moving and carrying, and also has the advantages of good working stability, good shock-resisting performance, long service life, capability of completely taking out sample oil and convenience for storing a sample after soil sampling and the like.

Description

technical field [0001] The invention relates to soil-taking equipment for geological survey, belonging to the technical field of geological survey tools. Background technique [0002] Geological survey is a geological survey and research work to find out the geological factors that affect engineering buildings. The geological factors that need to be surveyed include geological structure or geological structure: landform, hydrogeological conditions, physical and mechanical properties of soil and rock, natural geology Phenomena and natural building materials, etc. These are usually called engineering geological conditions. After the engineering geological conditions are identified, it is necessary to predict the way the engineering building interacts with the geological environment based on the structure and operating characteristics of the designed building. It is often necessary to use soil-taking equipment for sampling work in geological survey work. Among existing soil-tak...

Problems solved by technology

It is often necessary to use soil-taking equipment for sampling work in geological survey work. Among existing soil-taking equipment, such as a kind of soil-taking equipment for geological survey disclosed in Chinese Patent Document Application No. 201720541297.1, although this equipment can Sampling of hard soil, but the equipment is heavy and inconvenient to carry, and when taking soil, the soil layer cannot be completely preserved by breaking the soil layer, which is not convenient for subsequent analysis. The vibration generated during soil extraction is likely to affect the equipment and reduce the service life of the equipment. There is no storage box for reasonable storage of samples after soil extraction.

Therefore the existing earth-borrowing equipment for geological survey is still not ideal enough and cannot meet the needs of use.
