Hereinafter, a multipurpose weeding apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a multipurpose weeding apparatus according to the present invention, FIG. 2 is a cross-sectional view of FIG. 1, FIG. 3 is a perspective view of a weed section extracted from FIG. 2, and FIG. 4 is an operation diagram of FIG.

As shown in Figs. 1 to 3, the present invention relates to a multipurpose weeding apparatus having a structure in which a bucket of an excavator is replaced with a bucket to be linked to remove weeds and grass, as well as a billet can be cut.

The multipurpose weeding apparatus 100 is composed of three parts: a housing 10, a weeding section 20, and a wood cutting section 30.

The weed or grass is removed from the bottom of the housing 10, and the weed cutter 30 is connected to the bottom of the bottom of the housing 10 to cut the weed, .

A lid 16 is coupled to the upper surface of the housing 10 and a connection frame 161 connected to the excavator is protruded from the lid 16.

A hydraulic motor 11 is fixed to an inner center of the housing 10 to provide power to the weeding unit 20 and the wood cutting unit 30.

The hydraulic motor 11 is provided with a drive pulley 111 having a plurality of belt connecting grooves 112 at its upper portion so as to simultaneously transmit power to the weeding unit 20 and the wood cutting unit 30 .

The weed control unit 20 includes a first driven shaft 13 rotatably inserted into the tube 121 of the bushing 12 fixed to the bottom surface of the housing 10, And is rotated by the first driven pulley 131 coupled to the upper end.

The tubular body 121 of the bushing 12 is inserted into the housing 10 to support the first driven pulley 131. The first driven pulley 131 is coupled to the belt connecting groove 112 of the drive pulley 111, And receives the power of the hydraulic motor 11 by the belt B connected to the rotating shaft.

Accordingly, when the first driven pulley 131 rotates, the first driven shaft 13 coupled to the first driven pulley 131 rotates, and as the first driven shaft 13 rotates, And the weed portion 20 coupled to the weft 13 is rotated.

The weeding portion 20 is connected to the first driven shaft 13 exposed on the bottom surface of the housing 10 through the bushing 12 and has an arm 211 extending equally along the circumferential surface, (21).

At this time, the first cutter blade 22 and the second cutter blade 23 are hinged to the upper surface and the lower surface of each arm 211 with a single hinge shaft 24.

At this time, the rotary disc 21 can form four, five or six arms 211 depending on the number of the first cutter blade 22 and the second cutter blade 23, Of course.

The first cutter blade 22 and the second cutter blade 23 are coupled to the single hinge shaft 24 of the rotary disk 21 and rotate together.

Therefore, when the rotary disk 21 rotates, the first cutter blade 22 and the second cutter blade 23 rotate simultaneously to remove grass or weeds.

At this time, when the second cutter blade 23 and the first cutter blade 22 are struck against a stone or soil, they are rotated around the hinge shaft 24 to prevent breakage.

Further, the first cutter blade 22 and the second cutter blade 23 are simultaneously rotated at different heights, thereby making it possible to crush the grass or the stem of the weeds.

On the other hand, the second cutter blade 23 has a configuration in which the outer periphery is bent upward by the thickness of the bushing 12. Accordingly, the second cutter blade 23 can prevent the weed stem from being entangled with the bushing 12, thereby preventing the hydraulic motor 11 from being loaded.

The rotary disc 21 may also be provided with a blade (not shown) at an outer periphery thereof to remove the first cutter blade 22 and the weeds not removed from the second cutter blade 23 .

The cover 10 further includes a cover 15 surrounding the weed portion 20 to prevent the weed and turf from being scattered by the centrifugal force of the rotary disc 21.

Here, a discharge port 151 for discharging the removed weed is further formed at one point of the cover 15.

At this time, three blades 25 equally divided are further coupled to the upper surface of the rotary disk 21, and the removed grass is blown to the outer surface of the rotary disk 21.

As shown in FIG. 4, when the blade 25 is formed in an L-shaped cross-section and rotates, the blade 25 blows the inside air outward due to air resistance on the vertical plane.

Therefore, the centrifugal force of the rotating disk 21 and the grass or grass removed due to the blowing of the blade 25 can be discharged far away through the discharge port 151 of the cover 15, so that the shredded lawn or the grass is not collected .

The wood cutting portion 30 is connected to the other bottom surface of the housing 10 and rotates by the power of the hydraulic motor 11 to remove the burrs.

This wood cutting portion 30 is constituted by a rotary saw blade in the form of a circular disk.

The wood cutting portion 30 is connected to a second driven shaft 14 rotatably inserted into the tube 121 of the bushing 12 fixed to the bottom surface of the housing 10 and rotated.

At this time, the tube 121 of the bushing 12 is inserted into the housing 10 to support the second longitudinal coaxial shaft, and the second driven pulley 141, which is coupled to the upper end of the second driven pulley 141, And the belt B connected to the belt connecting grooves 112 of the first and second cams 111 and 111 receives the power of the hydraulic motor 11 and rotates.

Accordingly, when the second driven pulley 141 rotates, the second driven shaft 14 coupled to the second driven pulley 141 rotates, and as the second driven shaft 14 rotates, the second driven shaft 141 rotates, And the wood cutting portion 30 coupled to the frame 14 is rotated.

In the above-described multipurpose weeding apparatus 100, when the single hydraulic motor 11 rotates, the drive pulley 111 coupled with the hydraulic motor 11 rotates.

Then, the first driven pulley 131 and the second driven pulley 141, which are connected with the belt B, rotate together with the drive pulley 111.

Thereafter, the first driven coaxial shaft 13 and the second driven coaxial shaft 14 coupled to the first driven pulley 131 and the second driven pulley 141 rotate.

When the first driven coaxial shaft 13 and the second driven coaxial shaft 14 rotate, the weed portion 20 coupled to the first driven coaxial shaft 13 rotates, and at the same time, The cutting portion 30 rotates.

Accordingly, a structure is provided that can be rotated simultaneously with the timber cutting portion 30 and the weeding portion 20 to remove weeds and grass as well as thick barks.

The technical idea should not be construed as being limited to the above-described embodiment of the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Accordingly, such modifications and changes are within the scope of protection of the present invention as long as it is obvious to those skilled in the art.
