Soil sampling device for constructional engineering

Abstract

The invention discloses a soil sampling device for constructional engineering, and the device comprises a protection box, a positioning box, a sampling pipe, a lubricating mechanism, a dismounting mechanism and a damping mechanism; a motor is fixedly mounted in an inner cavity of the protection box, a driving shaft is arranged at one end of the motor, the driving shaft penetrates through the surface of the bottom end of the protection box, and the lubricating mechanism comprises a sleeve. According to the invention, through the arrangement of the sleeve, the long-time rotation friction force increase of the driving shaft on the motor at the bottom end of the protection box is effectively avoided, so a certain lubricating effect is achieved, the rotating efficiency of the driving shaft is improved, and the working efficiency of the device is further improved; through the arrangement of the pull handle, the problem that when the sampling pipe is damaged after long-time use and needs to be replaced, the dismounting process is tedious is effectively avoided, manpower is saved, the dismounting efficiency of the device is improved; through the arranged rubber columns, the situation thatvibration of the device cannot be buffered during working is effectively avoided, the stability of the device is improved, and the positioning accuracy of the device is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of sampling devices, in particular to a soil sampling device for construction engineering. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals, animals and plants from weathering of rocks, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. [0003] Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms through photoinhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. They are interrela...

Problems solved by technology

[0004] However, during use, the driving shaft on the motor of the sampling device rotates at the bottom of the protection box for a long time, and the friction force increases, which reduces the rotation efficiency of the driving shaft, thereby reducing the working efficiency of the device, and the sampling tube is damaged after long-term use and needs to be replaced. At the same time, the disassembly process is cumbersome, which reduces the disassembly efficiency of the device. Finally, there is a problem that the device cannot buffer the vibration of the device when it is working, and the stability of the device is poor, which has a certain adverse effect on the accuracy of device positioning. For this reason, we Propose a Soil Sampling Device for Construction Engineering
