Description

Apparatus of cutting and removing trees and plants}

The present invention relates to a vegetation removal crushing device, and more particularly, a vegetation removal device that is separately mounted on a bucket mounting portion of an excavator and driven by receiving hydraulic pressure from a hydraulic supply system provided in the excavator. It relates to a vegetation removal and crushing device that cuts and crushes vegetation or miscellaneous trees such as ragweed through instant hitting force.

In general, the removal work to remove lush weeds and miscellaneous trees in the summer season must be performed manually by the operator holding a mowing machine equipped with an engine or carrying it on the back, so the speed of work is slowed and a large amount of work can be performed. There is no, and accordingly, the need for a large number of working manpower has emerged as an unavoidable problem.

As technologies to compensate for these problems, Korean Patent Registration No. 10-0448278, Patent Publication No. 2012-0019093, and Utility Model Publication No. 2015-0000811 are disclosed.

Conventional weeding devices for excavators as described above are in a state in which a weeding device is mounted on the ground by mounting a weeding device to the excavator that can freely enter special areas such as grasslands, hills, and hills where vehicle entry is impossible. It is a device to perform weeding work while maintaining.

In a conventional weeding apparatus for an excavator including the above weeding apparatus, a support roller is installed horizontally at a lower side of the main body in order to support the main body on the ground so that the weeding operation can be smoothly performed.

These support rollers are rotatably provided to move the body while being rotated while being supported on the ground.

However, since the support roller installed in the conventional weeding device is connected to the main body via a bracket, problems such as bending of the bracket easily due to its own weight or external pressing force have occurred, and thus the support roller's natural function has not been exhibited.

In addition, the rotary-type vegetation removal device using an excavator may stop rotation or even break the rotation when a blade is caught on a thick tree, and rotation stops due to vines being wound around the rotating rotary. There were problems throwing away.

In order to solve this, the applicant installs a rotational degree in which an ax-shaped blade is formed on a drum-shaped rotating drum alternately with two-row blades and three-row blades in Korean Patent Application Publication No. 2017-0126360, and has a cutting means that prevents vine plants from winding. As a result, there has been proposed a vegetation removal and crushing device that cuts out vegetation or miscellaneous trees and crushes them simultaneously.

The vegetation removal device shown in FIG. 1 is a vegetation removal device having a link connection 50 that can be detachably coupled to a bucket mounting portion of an excavator, and is equipped with a hydraulic motor 40 and a rotation degree 20 that are rotated by hydraulic pressure. It includes a rotating drum 10 and a case portion 30 provided to rotate the rotating shaft 15 of the rotating drum 10.

When both ends of the rotating shaft 15 of the rotating drum 10 are supported and fixed by the left and right side frames 33, the left and right bearing parts 35 reduce frictional force due to rotation of the rotating shaft 15 of the rotating drum. It is provided at the binding site to be harmful.

However, in the present invention, crushing material is accumulated in the bolt nut portion of the blade between the drum and the blade during the operation of the crusher, so that crushing is not smoothly performed, or crushing is performed in the process of passing through the upper part of the crusher. There may be a case that the drum stops by being discharged or wound around the drum without losing, and there is a problem that the welding part is damaged at the fixed part welded to the drum due to the impact of crushing when crushing miscellaneous wood.
