Soil sample collecting device for geological exploration

Abstract

The invention discloses a soil sample collecting device for geological exploration. The soil sample collecting device comprises a machine frame; the machine frame is arranged in an inverted T shape; the left side and the right side of the bottom of the machine frame are in threaded connection with adjusting columns which are vertically arranged; the top of the machine frame is in screw connectionwith a screw rod; a first motor is fixed at the bottom of the screw rod; sliding grooves are formed in the left side and the right side of an inner cavity of the machine frame; a supporting plate is connected between two sliding blocks; the bottom of the first motor is connected to the top of the supporting plate; and the output end of the first motor is connected with a rotating shaft. A soil layer is crushed under the action of a drill bit and a crushing blade, then a soil sample is moved upwards under the action of a spiral propeller, and soil is pushed into a sampling barrel and is moved upwards, so that the pushed soil falls into an obliquely-arranged sampling box through a second threaded sleeve and is collected; and the second threaded sleeve and the sampling box are in threaded connection, so that the disassembly and installation of the second threaded sleeve and the sampling box are facilitated, and the sampling box can be replaced when the soil with different depths is collected.

Description

technical field [0001] The invention relates to the technical field of soil sample collection, in particular to a soil sample collection device for geological exploration. Background technique [0002] At present, in the excavation and construction sites of foundation pits such as subway construction and housing construction, it is necessary to collect soil samples for geological inspection and exploration. However, the existing soil sample collection devices have simple structures and relatively single functions when used. , and the moving method is relatively inconvenient, and it is not convenient for the staff to control the depth of soil sample collection, and the existing soil sample collection device often collects soil samples in one place first and then transfers them to the soil sample storage box, and then collects the next time , this method increases the number of soil sample transfers and increases the possibility of soil sample contamination.
