The weed cutting device for mounting an excavator can remove the vegetation to be clean in comparison with a vegetation removing method using a bucket of the excavator, which is not specially composed for removing vegetation.

Description

{Weed cutting machine for excavator}

The present invention relates to an excavator-mounted vegetation removal apparatus mounted on an excavator and rotatably driven. More specifically, the present invention relates to a vegetation removal apparatus for excavator mounting, which comprises a center block fastened to a shaft of a driving member mounted on an arm of an excavator, The present invention relates to an excavator-mounted vegetation removing apparatus comprising a plurality of plate-shaped cutter blades and capable of arranging a ground before a planting material.

Generally well-known lawn mowers are classified into those using gasoline as a fuel and electricity generated from a generator as a power source and motors of an agricultural manager as a power source.

As described above, the conventional lawn mowing machine using the lawn mower cuts the weeds by rotating the lawn mower at a high speed. Therefore, when the weeds growing in the graveyard or the rice paddy are removed, the lawn weed is wound around the rotary shaft. When the amount of weed that winds on the rotating shaft of the blade becomes large, the rotating shaft may stop due to the wound weed, or when the mowing blade rotating at a high speed hits a stone hidden in the weeds, the stone is repelled It is pointed out as a disadvantage that safety accidents such as damage to the worker or others around him may be caused.

In addition, since the lawnmower has to be used on the back of a worker, the power is so small that it is difficult to cut and remove food organisms such as small trees or tree branches, and a problem that a larger power source is needed is emerged.

The following is a representative prior art related to a vegetation removal apparatus to be mounted on an excavator.

Korean Patent Registration No. 10-0973116 relates to a cutting device for heavy equipment coupling, a concrete file cutting device and lawn mower including the cutting device, and includes a left and right angle adjusting engaging portion coupled to a front end of a boom of a heavy equipment, An angle regulating piston having one side connected to the side of the left and right angle adjusting engagement portion and the other side coupled to a side portion of the main frame portion, a cutter frame portion coupled to the main frame portion, A cutting blade coupled to the cutting motor and horizontally disposed therein, a first angle adjustment engagement pin receiving portion coupled to the left and right angle adjustment engagement portion to protrude toward the main frame portion, A second angle adjustment engagement pin receiving portion coupled to the main frame portion, a first angle adjustment engagement pin receiving portion, Wherein the main control frame includes a plurality of adjusting pins which are received in the second angle adjusting pin receiving portion, wherein when the adjusting pistons are compressed or elongated, And the angle is changed by relatively rotating.

Further, the above-mentioned prior art has realized the effect that the cutting device is combined with the heavy equipment such as an excavator to overcome the limit of the workforce and can perform an easy cutting operation. However, the structure is complicated, There is a concern that it is frequently caught in the connection part or the rotation part and it may cause frequent failure. Therefore, there is a need for continuous research and development to solve this problem.

Korean Registered Patent No. 10-0973116 (Jul. 23, 2010) Korean Registered Patent No. 10-0633396 (2006.10.02.) Korean Patent Publication No. 10-2012-0019093 (2012.03.06.)

The vegetation removal method and the apparatus of the present invention are designed to solve the problems of the prior art of the vegetation removal apparatus. The vegetation removal method and apparatus of the present invention can be applied not only to vegetation weed, There has been a problem of directly removing food organisms such as tree branches;

Most of the lawn mowers used by the workers have a small power, so that it is difficult to cut and remove food organisms such as small trees or tree branches.

It is a main object of the present invention to provide a solution to such a problem that the organisms such as small trees or branches have to be removed mainly by using a bucket of an excavator.

The present invention has been made to solve the above-

A center block to which the shaft of the driving member mounted on the arm of the excavator is fastened at the center; And a plate-shaped cutter blade having a length in a horizontal direction on the side of the center block and having a plurality of radial shapes.

As described above, the vegetation removal apparatus for excavator according to the present invention can be installed and used in an excavator generally used in the afforestation operation, so that it is not necessary to apply extra manpower for removing vegetative organisms to the afforestation area. Can be obtained;

Since the cutter blade is rotated by using the strong power of the excavator, it is possible to easily cut and remove the food organisms such as small trees or branches that can not be removed by the lawn mower used by the operator;

It is possible to obtain the effect of removing the food organisms more cleanly than the method of removing the biological organisms using the bucket of the excavator, which is not particularly configured for removing the living organism.
