In general, equipment such as a grass cutter is used to remove weeds and scarves that have grown up in the summer season. The grass cutter is equipped with an engine for generating power and a power transmission shaft for transmitting the power of the engine. A workbench formed so as to be long to be used, and a cutting blade which is rotated by the power of the engine at the end of the workbench.

However, in the conventional lawn mower, there is a problem that the operator feels fatigue easily as the worker must carry the engine with 20 to 30 kg of the engine on his / her shoulders and lifting the power transmission shaft and the cutting blade with the arm, There is a problem that even after finishing the work, the user can not normally live for a certain period of time.

To solve this problem, Korean Utility Model Registration No. 20-0478578 discloses a structure in which a housing (12) is installed at the front end of an excavator (1) through a clamp (2) and covers an upper surface and a side surface, A weighing apparatus includes a discharge guide 24 for guiding the weeds to the outside, a rotating shaft 30 installed at the inside of the housing for rotating at high speed by the hydraulic power of the excavator, A cutting member (50) slanting in the inside of the housing and provided to the left and right along the rotation axis to remove the weeds and barks wound on the rotating shaft, and a cutting member And a spacing member 60 provided on both sides of the lower side of the side surface of the housing and spaced apart from the bottom surface of the housing by a predetermined distance.

Since the weed machine for excavator as described above is cut by contacting the weed cut on the rotary shaft through the cutting member using the hydraulic device of the excavator, the overload is not applied to the rotary shaft, thereby preventing breakage of the hydraulic device.

However, such an excavator weaving machine can smoothly cut weeds, but it is difficult to cut easily such as weeds in the case of a bamboo grass. In particular, in the case of thick bamboo shrubs, There is a problem that the connecting portion of the cutting edge is broken or an overload is applied to the rotary shaft, which causes malfunction and breakage of the hydraulic device.

Here, the attachment 110 provided in the housing 100 is formed in various shapes according to the type of the heavy equipment to be mounted, and the hydraulic pressure of the heavy equipment is supplied to the hydraulic motor 120. The lower part of the housing 100 is connected to the rotary shaft 200, So that the weeds can be cut by the cutting member 400 rotating together with the wefts.

It is preferable that the housing 100 has a rake 130 protruding horizontally outwardly on one side to which the rotary shaft 200 is coupled so as to align the weighers or the weights with the cutting member 400 So that it can be cut easily.

The hydraulic motor 120 may be a vane motor, but it is preferable that a piston motor be used instead of the vane motor. Although the structure of the piston motor is complicated and expensive, This is because it can be rotated at a high speed with a high efficiency and a large output.

3, the guide member 300 is inserted into the outer surface of the rotary shaft 200 and is inserted into the rotary shaft 200 through the rotary shaft insertion hole 311 so as to be coupled with the rotary shaft 200 at a predetermined interval along the longitudinal direction thereof. The rotary shaft insertion portion 310 and the rotary shaft insertion portion 310 are integrally formed with the rotary shaft insertion portion 310. The rotary shaft insertion portion 310 and the rotary shaft insertion portion 310 are formed to have an arc- A guide supporting portion 320 having a concave guide 330 and a weir and a weir attached to an end of the guide supporting portion 320 and contacting the outer surface are moved toward the blade body 420 so as to be cut by the cutting blade 421 And a movement guiding part 340 guiding the guiding part 340 in a forward direction.

Since the installation space of the guide member 300 is kept constant through the rotation axis insertion unit 310, the guide member 300 and the cutting member 400 at mutually adjacent positions can be prevented from interfering with each other, The movement guide portion 340 can be firmly supported by the guide support portion 320 and is provided at a position adjacent to the cutting edge 421. The movement guide portion 340 is formed in a shape of an arc along the outer peripheral surface of the rotation axis 200, So that the movement of the weeds and the weeds can be guided to the cutting blade 421 side and cut smoothly.

The key groove 210 is formed in one of the outer circumferential surface of the rotary shaft 200 and the inner circumferential surface of the rotary shaft insertion hole 311 and the other is formed in a shape corresponding to each other so as to be tightly coupled with the key groove 210, It is preferable that the guide member 300 and the guide member 300 are installed in a mutually keyed manner so that the guide member 300 coupled to the rotation axis 200 is tightly coupled to the rotation axis 200, This is to prevent the guide member 300 from being idle during the cutting operation of the weeds and the weeds by the cutting edge 421.

The cutting member 400 includes a blade support 410 installed on the guide member 300 through a hinge shaft 411 fitted to the lower end of the blade attachment groove 330, A cutting blade 421 is provided at an upper end of the blade body 421 and cuts the weeds and the weft. The cutting blade 421 is provided at the tip end of the rotating shaft 200 in the forward and backward directions, (420).

At this time, the blade body 420 may be formed integrally with the blade supporting portion 410, but may be detachably coupled to the blade body 410 by welding or by using a bolt and a nut. It is preferable to protrude from the outer circumferential surface of the guide member 300 in order to easily cut off the weeds and the weeds whose movement is guided by the guide 300.

In addition, it is preferable that the guide member 300 is fitted to the rotary shaft 200 so that the cutting members 400 coupled to the adjacent guide members 300 are installed at different positions, The cutting member 400 coupled to the member 300 is formed in a screw shape along the longitudinal direction of the rotary shaft 200. This is because the weeds and the brush are not pushed by the wind generated as the rotary shaft 200 rotates But rather smoothly flows in the direction of the rotation axis, so that a rapid cutting operation can be performed.

In order to keep the distance between the guide member 300 and the cutting member 400 at a constant distance from each other during the cutting of the articles and the blanks, a spacing support plate 140 supported on the ground is formed on the lower surface of the housing 100 Although not shown, the spacer support plate 140 is mounted on an elastic member installed to apply an elastic force to the housing 100 in an upward and downward direction. The impact generated by the contact with the ground surface is transmitted to the housing 100 A height adjustment hole is formed in the side surface of the housing 100 so as to pass in the upward and downward directions and a height adjustment is possible through a fixing member fitted in the height adjustment hole, The height can be adjusted.
