Soil auger

Abstract

A soil auger belongs to the technical field of soil appliance and is applied in soil sampling. The soil auger comprises a drill, a screw, a drill barrel, a handle, a transverse tie rod, a diagonal tie rod, a pedal, a slide block, a support and a soil outlet groove. The upper end of the screw is connected to the handle, and the lower end of the screw is connected to the upper end of the drill. The screw is provided with external thread which matches internal thread of a nut, which is in threaded connection to the screw. The upper end of the drill barrel is connected to the nut. The support is welded at the lower end of the drill barrel. The drill is arranged inside the drill barrel. One end of the transverse tie rod is fixed on the support through welding, and the other end of the transverse tie rod is connected to the pedal. One end of the diagonal tie rod is connected to the middle position of the transverse tie rod, and the other end of the diagonal tie rod is connected to the drill barrel through the slide block. The transverse tie rod, the diagonal tie rod and the pedal form a foldable pedal device. The soil auger of the invention is convenient for dismounting and replacement of the drill and the drill body. The function and practicality of the soil auger are enhanced. The soil auger is reasonably designed, is easy to carry, is time-saving and labor-saving to operate, is convenient for soil sampling, and is convenient for promotion and application.

Description

technical field [0001] The invention belongs to the technical field of soil tools, and in particular relates to a soil drill. Background technique [0002] In the research of ecology and soil science, the collection and analysis of soil is of great significance. When carrying out agricultural production, soil pollution control, animal and plant research, etc., it is often necessary to sample field soil. The most basic tool for these tasks is the soil auger. [0003] At present, existing soil drills are usually artificial soil drills and electric motor soil drills. But the drill body and drill bit of the artificial soil drill in the prior art have a single connection relationship. When this soil drill takes soil, the drill shank pushes the drill rod, and the drill bit goes deep into the soil. It is difficult, time-consuming and labor-intensive, and the work efficiency is low; secondly, when taking soil, it is necessary to hit the drill pipe with a hammer to provide the power...

AI Technical Summary

Problems solved by technology

But the drill body and the drill bit of the artificial soil drill in the prior art have a single connection relationship. When this soil drill takes soil, the drill shank pushes the drill rod, and the drill bit goes deep into the soil. It is difficult, time-consuming and labor-intensive, and the work efficiency is low; secondly, when taking the soil, it is necessary to hit the drill pipe with a hammer to provide the power to take the soil. Sampling is particularly laborious

[0004] Although the electric soil drill is less labor-intensive than the artificial soil drill, the cost of the electric soil drill is high, and it is not suitable for wide application; secondly, the electric soil drill is too large, and it is inconvenient to carry and operate when going out.

Therefore, when soil sampling is carried out with the existing soil auger, it brings great difficulties to the work
