Problems solved by technology

The traditional soil drill is to fix the handle on the soil drill rod, and the downward force is generated by rotating the handle and downward force to make the soil drill move downward; because the handle can only be rotated in one direction, it needs to be inverted repeatedly during the rotation process. hand, even the operator needs to follow the handle to rotate around the drill pipe
The operating handle is fixed at a certain height and cannot move up...

Abstract

The invention discloses a soil drill. The soil drill comprises a handle, a flywheel mechanism, a drilling rod and a drilling head arranged at the end portion of the drilling rod; the flywheel mechanism comprises a steel box in inside gearing with an unidirectional-rotation ratchet mechanism, and a steel shaft nested to the ratchet mechanism, the centers of the steel box, the ratchet mechanism and the steel shaft are respectively provided with a circular through hole, the drilling rod traverses the circular through holes and is clamped to the steel shaft, and the steel box is fixedly connected with the handle from the outside; and the flywheel mechanism drives the drilling rod to rotate in an unidirectional mode after the handle is rotated. The soil drill has the advantages of labor saving, time saving, and substantial improvement of the soil sampling work efficiency.

Description

technical field [0001] The invention relates to the technical field of soil sampling machinery, in particular to an earth drill. Background technique [0002] During soil and subsurface root sampling, deep soil sampling is often performed. The traditional soil drill is to fix the handle on the soil drill rod, and the downward force is generated by rotating the handle and downward force to make the soil drill move downward; because the handle can only be rotated in one direction, it needs to be inverted repeatedly during the rotation process. The hand, even the operator needs to follow the handle to rotate around the drill pipe. The operating handle is fixed at a certain height and cannot move up and down. If it is too high or too low, it will affect the operator's strength; at the same time, deep soil sampling requires a longer drill pipe, which makes the length of the drill pipe too long, which affects the firmness of the material. It is also very demanding. Therefore, w...
