Novel planting earth auger

Abstract

The invention discloses a novel planting earth auger which includes a gasoline engine, two handle frames, a gear box and a drilling rod. The gear box is connected to the bottom of the gasoline engine. The bottom of the gear box is fixedly disposed on a supporting base. The handle frames are disposed on both the two ends of the supporting base respectively. The drilling rod penetrates the supporting base and is connected to the gear box in a transmission manner. A plurality of propeller blades are disposed on the drilling rod in the axial direction at equal interval. Each propeller blade is composed of a right-up-rotating blade and a left-down-rotating blade in an integrated manner. A plurality of triangle teeth are formed on the edge of each propeller blade successively. Two ends of the supporting base are connected to a square-shaped moving frame in a vertically sliding manner. A positioning plate is transversally disposed between two vertical support legs, which are closed to the bottom, on the square-shaped moving frame. An elastic buffer protective device is disposed between the positioning plate and the supporting base. The planting earth auger is simple in structure and high in feasibility, is good in positioning, can form a pit being uniform in depth, is high in accuracy, reduces labor force output, is convenient to move and is high in pitting efficiency.

Description

technical field [0001] The invention relates to a digging machine, in particular to a novel tree planting digging machine. Background technique [0002] The pit digging machine is a special machine for fast digging of pits for afforestation and fertilization in mountains, hills, and gullies. The digging machine frees people from heavy physical labor and is widely used in afforestation, planting fruit forests, fences, and fertilizing fruit trees in autumn. It has strong power, beautiful appearance, comfortable operation, low labor intensity, suitable for various terrains, high efficiency, easy to carry and field field operations. [0003] The advantages of existing digging machines, especially semi-automatic digging machines, are that they are suitable for family-based farmers to plant trees and dig pits, which can reduce the trouble and complexity of traditional shovel-type digging, reduce labor force, and improve agricultural productivity. Efficiency, but the existing hou...

Problems solved by technology

[0003] The advantages of existing digging machines, especially semi-automatic digging machines, are that they are suitable for family-based farmers to plant trees and dig pits, which can reduce the trouble and complexity of traditional shovel-type digging, reduce labor force, and improve agricultural productivity. Efficiency, but the existing household digging machine needs to manually hold the handle frame of the digging machine in the actual use process, so under the action of dynamic vibration, it is difficult to dig the pit accurately , and in the case of vibration, manually holding the handle frame to dig a hole will undoubtedly cause vibration and oppression to the arm, and long-term use will cause harm to the body
