Sampling device for geological mineral exploration

Abstract

The invention provides a sampling device for geological mineral exploration, relates to the technical field of geological sampling, and solves the problems that the pulling convenience of a barrel cannot be improved through structural improvement, and a pulling structure cannot be matched with a pulling structure of a ground nail, and the problem that the soil on the sampling cylinder cannot be automatically cleaned. The sampling device for geological mineral exploration comprises a frame body, wherein a sampling structure is connected to the frame body in a sliding manner, two ground nails are inserted into the frame body, and the two ground nails are both connected with soil in an inserted manner. Two elastic telescopic rods are symmetrically welded on the frame body and are in contact with the outer wall of the barrel body; grooves are formed in the outer wall of the cylinder body in a rectangular array shape, and the grooves are of an annular groove-shaped structure; and when the cylinder body moves upwards by 20cm, the groove makes contact with the head end of the elastic telescopic rod, and the groove and the elastic telescopic rod jointly form a vibration cleaning structurefor soil in the through hole.

Description

technical field [0001] The invention belongs to the technical field of geological sampling, and more specifically relates to a sampling device for geological and mineral exploration. Background technique [0002] In geological prospecting, taking soil samples back to the laboratory for comparative testing and research is the most commonly used exploration method, and soil sampling is usually carried out by field workers. [0003] For example, the application number: CN202020294820.7, the utility model discloses a sampling device for geological mineral exploration, the technical field of sampling equipment for geological research, and solves the problem that the existing sampling device has relatively large limitations in soil depth. It includes a top plate, the four corners of the bottom of the top plate are fixed with support feet, two mutually symmetrical slots are opened on the top of the top plate, both of the two slots pass through the top plate, and the inside of the t...
