Novel soil sampling device

Abstract

The invention discloses a novel soil sampling device. The novel soil sampling device comprises a drilling rod, a heart-shaped drill bit, a spiral type drill bit, an annular cutter sampling device, an extending rod and a spirit level and is characterized in that the spirit level is arranged at the top of a handle; tenon and mortise structure joint connectors are arranged at two ends of the drill bit and the handle; the handle and a drilling rod can be extended or the drill bit can be replaced by utilizing the tenon and mortise structure joint connectors. According to the novel soil sampling device disclosed by the invention, the length of the drilling rod can be extended through tenon and mortise structure joint, so that the sampling of a relatively deep soil layer can be carried out; when the drill bit is replaced, different types of soil samples can be collected; the verticality of punching is ensured through observing the water level, so that the novel soil sampling device has the characteristics of deep drilling, accuracy in punching, detachability, light weight, wide application, convenience for carrying and the like.

Description

technical field [0001] The invention relates to the technical field of soil collection tools, in particular to a novel soil sampler. Background technique [0002] Soil drills are widely used in soil, geology, water conservancy, environmental protection and other fields, and are mainly used to collect soil or soil samples. Its development is conceived in soil science and geology, and can promote and promote the development of soil science and geology. At present, the commonly used soil drills are mostly "T" type soil drills, which are composed of a drill rod and a drill bit installed at the bottom of the drill rod. First of all, the length of the handle and the drill pipe cannot be adjusted freely. When the soil drill goes deep into the soil layer, due to the short drill pipe and the large resistance, it is difficult to rotate the handle, and it is laborious to drill the soil; At this time, the traditional soil drill cannot guarantee the verticality of the hole. In the proc...

AI Technical Summary

Problems solved by technology

First of all, the length of the handle and the drill pipe cannot be adjusted freely. When the soil drill goes deep into the soil layer, due to the short drill pipe and the large resistance, it is difficult to rotate the handle, and it is more laborious to drill the soil; At this time, the traditional soil drill cannot guarantee the verticality of the hole. In the process of drilling down the soil, the excessive inclination angle will bring a large error, resulting in insufficient excavation depth; third, the commonly used soil The drill bit and the drill pipe are connected by welding, and the drill bit cannot be replaced, and the soil drill can only collect disturbed soil, but cannot collect undisturbed soil samples, and it is impossible to use one drill for multiple purposes
