BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excavator,

The present invention relates to a plant removing apparatus for an excavator, and more particularly, to a pair of horizontal rotating bodies provided at a predetermined interval in parallel to a fore end of an operating arm of an excavator, a saw blade for removing grass, The present invention relates to a plant removing apparatus for an excavator, which is capable of safely and efficiently removing a large area of vegetation.

Generally, the weeding for removing weeds, lawns, and brushes is carried out manually by lifting a cutter equipped with an engine by hand or the like, so that the heavy equipment easily feels fatigue by the heavy equipment, I could not do a lot of work because the work was slowed down.

In addition, when a cutting machine is used, a high-speed rotating cutting blade causes a lot of safety accidents due to the occurrence of safety accidents of the workers. Therefore, the working efficiency is limited in wide fields, orchards, etc. .

In recent years, there has been a method in which a lawn mower is mounted on a bumper of a general vehicle and then used to remove the vegetation of various places more effectively by using the power source of the vehicle. However, there is a problem in that the lawn, grassland, Such as weeds and bushes that breed lushly in special areas such as the United States.

In view of this, an excavator having a herbicidal means has been disclosed in Korean Patent Application No. 10-2004-18093. This herbicide is installed at the tip of the working arm of an excavator for excavating soil or rock, It was proposed to weed weeds and bushes that grew in special areas such as grasslands, hills, and hills.

However, since the excavator having the above-described conventional weeding means is capable of removing the grass or grass by a single structure herbicide blade, the herbicide is a structure that can remove relatively soft material such as grass. Therefore, In addition, there is a problem that the herbicide is not easily removed, and when the herbicide strikes a strong substance such as a stone in the herbicidal action such as grass, the herbicide is damaged and safety accidents are likely to occur.

In addition, in the case of having a horizontal herbicidal blade, it is not possible to broaden the turning radius of the structurally rotated horizontal herbicidal blade, so that it is not possible to weed a large area. In addition, There is a problem that the efficiency of the operation is deteriorated because the separation process can not be performed to one side.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a horizontal rotating body provided in parallel with a fixed frame on a fixed frame mounted on an operating arm end of an excavator, The plant removing member is a saw blade for removing the grass or a saw blade for removing the grass, and a foreign matter removing member for removing foreign substances such as stones is provided at the front end and the rear end of the fixing frame, The plant can be removed safely and efficiently.

Further, the cutting blade attached to the vegetation removing member of the present invention for removing the grass is provided with a shaft rotating type between a guide plate constituting a rotating disk and a supporting plate. When the cutting blade hits a stone or the like, the cutting blade is inserted between the guide plate and the supporting plate Thereby preventing damage to the cutting edge and preventing a safety accident from occurring.

The present invention relates to a fixing frame which is composed of a rectangular frame, a fastening part which is installed on one side of the upper face of the fixing frame so as to be detachable and can be fastened to the front end of the operating arm of the excavator, A horizontal rotating body fixedly installed on both sides of a rotating shaft part connected in parallel to each other by a belt so as to be interlocked with each other and to transmit rotation force of the rotating power unit; A plant removing member provided with fastening means for removing and attaching the planting member and a foreign matter removing member protruding from the front end and the rear end of the stationary frame, respectively.

And the fastening part is provided with a fastening guide rod between the vertical supports and fastened to a fastener provided at the end of the operating arm of the excavator.

And the rotary power unit generates a rotational force as a rotational power source by hydraulic pressure supplied from an excavator.

The center of the horizontal rotary body is fitted into the rotary shaft portion and is coupled to the inside of the protruded tip of the rotary shaft portion and a plurality of screw engagement holes are formed in the horizontal rotary body so that the vegetation removal member can be detached and attached by bolts .

The vegetation removing member may be any one of saw blades installed on a first rotating disk and installed on a cutting blade or a second rotating disk for removing the grass, and a saw blade for removing the grass.

The first rotating discs are provided as a pair of guide plates having guide grooves into which a cutting blade can be inserted and flat plate-like support plates, so that a cutting blade can be rotated between the guide plate and the support plate, At regular intervals.

And a saw blade radially protruding at regular intervals around the second rotating disk is fixedly fixed to the saw blade, and the saw blade has sharp ends and a plurality of teeth on both sides of a triangular contact surface inclined to both sides.

The plant removal device for an excavator according to the present invention is composed of a vegetation removal member which is installed on a horizontal rotary body of a fixed frame mounted on an end portion of an operation arm of an excavator and is attached and detached, A saw blade for removing scum, and selectively fastening the saw blade to securely and efficiently remove a large area of vegetation.

In addition, the cutting edge for removing the grass has a structure in which the cutting blade is rotated by the contact resistance when it comes into contact with a foreign material such as stone concealed by the grass, and is inserted between the guide plate and the support plate. It is possible to smoothly remove the burrs by the saw blade when removing the burrs such as the branches, and the foreign matter such as stones can be pushed outward by the foreign matter removing part to perform the operation, The efficiency can be greatly improved.
