Portable power rotary device provided with drill having earthwork and cut-off functions

Abstract

A rotary device having mounted therein a drill for soil earthwork. The drill includes a shaft and a screw, formed along the outer circumferential surface of the shaft, for earthwork and the transportation of displaced soil. A rotary shaft is formed on the upper part of the shaft. A fixed shaft part is formed on the lower part of the shaft, for being inserted and rotated into the soil. A pair of horizontal blades face each other on the connection part between the shaft and the fixed shaft part. Cutting blades, which are symmetrical with each other, incline downwardly on the pair of horizontal blades. Vertical blades protrude vertically on the upper portion of the lower wing of the screw and, when performing earthwork, soil and tree roots are cut by the cutting blades, and soil lumps, transferred along the screw, are cut again by the vertical blades.

Description

TECHNICAL FIELD[0001]The present invention relates to a portable power rotary device provided with a drill having earthwork and cut-off functions, and more particularly, to a portable power rotary device provided with a drill having earthwork and cut-off functions, which excavates soil and cuts tree roots tangled like a spider's web using cutting blades, formed on a pair of horizontal blades, by inserting a fixed shaft part of the drill rotatably mounted in a rotary body into the soil and fixing the same to its location, and then rotating the drill, and also, cuts the soil again using vertical blades and then transports the soil upwardly through a screw.BACKGROUND ART[0002]In general, about 65% of our country's total land area (South Korea) is covered by mountain areas including woods and fields, and mountain areas are important factors for establishing country's policies. Therefore, the government aggressively pursues utilization of mountain areas as resources and applying policies...

AI Technical Summary

Benefits of technology

The present invention provides a portable power rotary device with drill that can easily cut soil and tree roots, and transport them upwardly by the screw without leaving the drill location. The device can also perforate steel pipes and walls, and effectively excavate places with less obstacle or soft soil. The drill can be easily rotated and has good workability, resulting in easy cropping and harvesting of high price medicinal herb roots. The device is easy to carry, can be used vertically or horizontally, and can be designed for high or low speed and light / heavy load, making it more efficient and effective for agricultural and forestry applications.

Problems solved by technology

However, unlike in farmland, mechanization in mountain areas is almost impossible due to the characteristics of the mountain areas, such as steep slopes, obstacles such as trees, incomplete access roads, or the like, and soil conditions of tree roots, grass roots, and stones are poor.

In addition, working with manpower has become more difficult due to chronic labor shortage in farm villages, aging society, and evasion of manual labor.

However, soil and tree roots may not be completely crushed only by the horizontal cutting blades.
