Problems solved by technology

Because the existing soil-breaking bit has only one soil-breaking end, the soil-breaking effect is poor, and it is difficult to smash the soil and send out the soil in an environment with high soil compactness.

Embodiment 1

[0023] The high-efficiency ground-breaking bit includes a main shaft 5, a spiral guide vane 4 connected to the main shaft, and a ground-breaking end; the ground-breaking end includes an outer ground-breaking end 1, an outer ground-breaking end 3, a central ground-breaking end 2, and a central soil-breaking end 6; the outer ground-breaking ends 1 and 3 are fixed At the symmetrical position of the spiral guide vane 4, the central soil-breaking ends 2 and 6 are connected to the end of the drill bit main shaft 5, the connection line of the outer soil-breaking ends 1 and 3 is perpendicular to the connection line of the central soil-breaking ends 2 and 6, and the work of the outer soil-breaking ends The radius is larger than the working radius of the central ground-breaking end, and the space distribution of the four ground-breaking ends is even in the working range, increasing the ground-breaking area. The central soil-breaking ends 2 and 6 are bifurcated structures with a central a...

Abstract

The invention discloses an efficient soil breaking drill bit. The efficient soil breaking drill bit comprises a spindle, a spiral guide vane connected to the spindle, and a soil breaking end. The soil breaking end comprises two outer side soil breaking end bodies and two central soil breaking end bodies. The outer side soil breaking end bodies are fixed to the symmetrical positions of the spiral guide vane. The central soil breaking end bodies are connected to the tail end of the spindle of the drill bit. The soil breaking drill bit is good in soil breaking effect in a high compacting degree environment, high in broken stone passing ability, low in energy consumption, simple in structure and easy to machine.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an efficient soil-breaking drill bit. Background technique [0002] Afforestation, fruit tree planting, tree transplantation, topdressing pit digging and other tasks require frequent digging operations. In environments with high soil compactness or soil environments with a lot of gravel, general burrowing tools or The drill does not work properly. In particular, the output power of portable hole punching machinery is generally small, and more efficient ground-breaking drill bits are needed. Because the existing soil-breaking bit has only one soil-breaking end, the soil-breaking effect is relatively poor, and it is difficult to crush the soil and send it out in an environment with high soil compactness. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency soil-breaking drill b...
