[Background Art]
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.
In recent years, a national afforestation plan is required to prevent yellow dust from China or fine dust or to support “Growing Trees” for North Korea, and cropping and cultivation in mountain areas are increasingly performed for personal purposes along with a well-being trend for living to be 100 years old and a healing trend, and with the increase in high-income specialty crops, scientific farming, and the number of people returning to farming. Therefore, the government is institutionally and actively encouraging people to utilize the mountain areas and is supporting by supplementing the Forest Law, Management of Mountainous Districts of Act, or Promotion Act. Accordingly, short-term forest products such as traditional medicinal hubs, health foods, and wild hubs and vegetables are increasingly cultivated in mountain areas, and fruit trees or seedling are increasingly planted. In addition, farming in mountain areas is increasing to utilize idle farmland and to spread farming in a city.
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. Therefore, there is an acute need for development of portable mechanization equipment for agriculture and forestry.

Referring to FIGs. 1 to 6, the portable power rotary device provided with the drill having the earthwork and cut-off functions according to the present invention will be describeld hereinafter.
The portable power rotary device 10 (hereinafter, referred to as a rotary device) provided with the drill having the earthwork and cut-off functions of the present invention has a drill 30 rotatably mounted therein for excavating soil 50, and the rotary device 10 includes a rotary body 20 and the drill 30.
As well-known and widely used, the rotary body 20 has a decelerator and a driving engine embedded therein, and has a rotary shaft 31 of the drill 30 attachably and detachably connected thereto to pivot about a perforation shaft 21, and then rotates the connected drill 30 to use the drill 30 for many purposes, such as planting a seedling, earthwork in a place which equipment cannot enter or a little piece of land, excavating a hole for installing a fence wood pillar, or perforating a lumber pillar of a Ginseng field. Therefore, an inner structure and an operation relationship of the rotary body 20 will not be described in detail.
The portable power rotary device 10 provided with the drill having the earthwork and cut-off functions of the present invention is the rotary device 10 having the drill 30 rotatably mounted therein for excavating soil 50, and the drill 30 is made of metallic material and is designed to excavate soil 50 in a mountain area. The drill 30 may include a shaft part 32 formed of a circular metal rod, a screw 35a and 35b formed along the outer circumferential surface of the shaft part 32, for excavating soil 50 and transporting the excavated soil, a rotary shaft 31 formed on the upper part of the shaft part 32, a connection socket 40 formed on the rotary shaft 31 for adjusting length, and a fixed shaft part 37 formed on the lower part of the shaft part 32 for being inserted and rotated into the soil 50 to be excavated. A pair of horizontal blades 33 are formed on the connection part between the fixed shaft part 37 and the shaft part 32 to face each other. The screw 35a and 35b has layers formed one on the other and symmetrically and integrally connected to each other on the pair of horizontal blades 33, for transporting soil upwardly. Cutting blades 34 are inclined downwardly to be symmetrical to each other and are integrally formed on the -8- pair of horizontal blades 33. A plurality of vertical blades 36 protrude vertically from the upper portion of the lower wing of the screw 35a and 35b, and are formed to be spaced apart from one another at a predetermined distance. When soil is excavated, soil and tree roots are cut by the cutting blades 34, and lumps of soil 50, transferred along the screw 35a and 35b, are cut again by the vertical blades 36.
The cutting blades 34 formed on the horizontal blades 33 have blade parts 34A formed on lower ends thereof and inclined inwardly, for cutting tree roots during excavation and transporting soil 50 toward the screw 35a and 35b.
The vertical blades 36 formed on the upper portion of the lower wing of the screw 35a and 35b have edges formed in a saw-tooth shape or a diamond shape and inclined, and are formed by welding or attachably or detachably formed.
The edges of the vertical blades 36 are inclined so as to prevent an overload from being applied to the screws 35a and 35b when lumps of soil 50 and tree roots are cut.
The fixed shaft part 37 has a cutout groove 37a formed on the center of the lower end thereof and thus has excavation blades 37b twisted to cross each other, for digging into soil by itself without pressing the device.

The connection socket 40 is connected to the rotary shaft 31 to adjust the length of the drill 30, so that a worker can work in a comfortable position and thus fatigue can be reduced, or when it is necessary to increase excavation depth, a connection socket 40 of a different size may be connected and used.
[Mode for Embodying the Invention]
The use state of the portable power rotary device 10 provided with the drill having the earthwork and cut-off functions as described above will be described. -9-
Referring to FIG. 4, a user grips the rotary body 20 having the drill 30 mounted thereon and fixes the fixed shaft part 37 of the drill 30 in soil to be excavated, and then rotates the drill 30 by driving the rotary body 20.
Alternatively, the user may rotate the drill 30 and then insert the rotating fixed shaft part 37 to soil to be excavated, and the fixed shaft part 37 may be easily inserted into the soil by the spiral 37d of the fixed shaft part 37.
Thereafter, the drill 30 being inserted into the soil 50 by the fixed shaft part 37 and being supported is rotated, and the blade part 34a of the cutting blades 34 formed on the horizontal blades 33 excavate the soil 50 and also cut tree roots. The excavated soil is cut again by the plurality of vertical blades 36 formed on the lower wing of the screw 35a and 35b and the soil is transported upwardly by the screw 35a and 35b and is discharged to the outside. In this way, a series of earthworks is finished.
In this case, the plurality of vertical blades 36 are provided on the wing of the screw 35a and 35b, and thus cut the soil 50 raised along the screw 35a and 35b again, and the crushed soil and tree roots are transported upwardly by the screw 35a and 35b, so that earthwork can be easily performed.
Since the lumps of the soil 50 are cut by the vertical blade 36 as described above, the soil is prevented from being tangled and enclosing the shaft part 32 and thus a load can be prevented from being applied to an engine.
The cutting blades 34 formed on the horizontal blades 33 excavate the soil and simultaneously cut the tree roots, and the excavated soil and the cut tree roots are guided by the screw 35a and 35b and the soil lumps are cut again by the vertical blades 36 and are transported upwardly.
Inconvenience that may be caused by the drill 30 being shaken by imbalance during the earthwork or not being easily mounted on an inclined surface and sliding out can be prevented by the fixed shaft part 37, and soil can be very finely and lightly ground by rotating the left and right excavation blades 37b, which are thin and strong, at high speed, so that a plowing effect and a grinding effect of a management device can be obtained simultaneously. Therefore, a subsequent work can be easily performed and there are effects of forming pores of soil, enhancing air permeability, and reducing -10- harmful microorganism.
In addition, tree roots may be raised without being cut due to a misaligned angle of the cutting blades 34. In this case, the tree roots may be exactly cut again by the horizontal blades 33, so that the engine can be prevented from being stopped by the tension of the roots, and the work can be continuously and smoothly performed.
In addition, the plurality of connection sockets 40 may be provided on the rotary shaft 31 of the drill 30 to adjust the height of the device according to a gradient or a difference in heights of workers, or desired excavation depth.

In particular, the present invention relates to the portable power rotary device provided with the blade part 36a of the sharp vertical cutting blades 34, in addition to the horizontal blades 33 having dial earthwork and cutoff functions, which can easily perform the works without damaging roots during -11 - harvest, and also, can make a contribution to public functions such as flood prevention by enhancing a water-containing function in a mountain area.
Therefore, the present invention can utilize mountain areas as resources and enhance farmland efficiency, and also can perform very efficient works in substituting for tree-planting works such as landscaping or afforesting, traditional “shovel” works or rotary works, which depend on labor force in various construction sites. Therefore, the present invention can make a great contribution to elimination of labor and energy saving, and also can make a contribution to effectiveness thereof and industry.
As described above, the present invention relates to a device which is easy to carry and operate for the purposes of enhancing efficiency of various “earthworks” or “shovel works” such as cultivating a mountain area, cultivating medicinal hubs, digging for seedlings, digging waterway, landscaping, laying out a city vegetable garden, or the like, and of replacing and supplementing a tractor or a management device in a little piece of land or a mountain area where large scale equipment cannot enter.
In addition, the present invention provides the portable power rotary device provided with the drill having the earthwork and cut-off functions, which can minimize mechanization of the rotary device so that anybody can simply operate the device, and shows excellent efficiency 5-10 times higher than that of manpower works, and thus enhances quality of soil by forming pores, enhancing air permeability, and reducing harmful microorganism, and also improves efficiency such as easy cropping and easy harvesting of roots, and enables deep plowing, agitating, and pulverizing.
While preferred embodiments of the present invention have been described, the present invention may make various changes and use equivalents. It is obvious that the present invention can make appropriate changes to the above-described embodiments and equally apply the embodiments. Accordingly, the above-described matters do not limit the scope of the present invention which is defined by the limit of the claims presented below.
