Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-

The present invention relates to a multipurpose work machine for an excavator, and more particularly, to a multipurpose work machine for an excavator, which is capable of being manufactured in various forms according to the object of a work object so as to be replaced with a fork- And an adjustment unit for controlling the work performing unit according to the nature and purpose of the work, so that the speed of the work performing unit To a multipurpose work machine for an excavator, which is capable of adjusting the pivoting motion and providing the work progress.

Generally, the end of the arm of an excavator is only used as a fork-type container, and is used only for the purpose of transporting wastes or building wastes during construction work.

Due to the limited use of these excavators, excavators are not utilized in other field operations and remain in a state of being left untouched.

In order to improve the utilization of the excavator, the present inventor has filed a patent application No. 10-2013-0085288.

The technique of this application No. 10-2013-0085288 further improves the use of an excavator to provide a portable connector for connection of a forceps (trimming, trimming) and forceps to large trees such as forests or street trees .

However, the above-described technique is characterized in that the connection rotary connector for fastening the clamp to the arm end of the excavator does not suggest various types of work performing parts for performing the work according to the purpose of the construction work, I can not expect to fulfill work that meets my job objectives.

In addition, the device to be fastened to the arm end of the excavator generally includes a portion that provides a large amount of power, a body portion that is rotated by the power, and a hinge portion that is connected to the body by a hinge to perform various functions (A part for providing power, a body part, and a part for performing work) fastened to the arm end of the excavator according to the nature and purpose of the work .

As such, replacing the entire apparatus (the portion for providing power, the body portion, and the portion for performing the work) fastened to the arm end of the excavator results in an increase in replacement cost, Increasing fatigue and delaying replacement time due to excessive weight in the replacement process.

In addition, when an example of a part of a component of an apparatus to be engaged with an arm end of an excavator is used for cutting (use for picking up an object or battery), the operating speed of the cutting part is uniformly constant, It is impossible to expect efficiency in construction work requiring fine adjustment. When one of the opposed cutting (blade) portions is separated and the remaining one is required, the separated side is also operated. There was a problem that it acted as an element.

In addition, even if the object (eg, trees) is cut, it is necessary to mobilize a separate heavy equipment such as a crane during the process of loading the cut object (eg, a tree) into the freight vehicle. Since it is necessary to adjust the mounting of the trees in the process of loading in the freight vehicle, the worker adjusts the mounting of the trees with the manpower directly, thereby increasing the fatigue of the workers. This also causes the accumulated fatigue, Causing injury or injury to the human body.

On the other hand, as technologies to be compatible with the aggregators fastened to the arm of the excavator, there are a number of technologies that can be applied to the excavator as disclosed in Japanese Patent No. 10-1068130 (Patent Document 1), Japanese Patent Application No. 10-0920711 (Patent Document 2), Registered Patent No. 10-1141540 Patent Document 3), Patent No. 10-1130994 (Patent Document 4), Published Patent No. 10-2013-0078418 (Patent Document 5), Published Patent No. 10-2013-0069286 (Patent Document 6) There is a bar.

Although the upper and lower tongs can pick up or collect objects such as large glazed gravel, wood, scrap metal and the like, they are not suitable for the purpose of crushing, and there are limitations in performing various work purposes at the construction site. When fastening a site suitable for various construction work purposes, all of the reinforcing brackets, bearing frames, upper pincers, and lower pincers, which are fastened around the link part of the excavator's arm end, Which causes the hassle of replacement.

Therefore, it is difficult to cope with the purpose of crushing or conveying the object, which is used only for the purpose of simply picking or dropping large objects, and the operation method of the clamp is also different from that of the present invention. Adjustments to speed or pause can not be adjusted appropriately depending on the situation and are not suitable for work environments where precise or fine work is required.

Japanese Patent Application No. 10-0920711 (Patent Document 2) discloses a structure in which a crusher cutter having a cylindrical shape and a blade portion provided on an inner surface of a flywheel provided in the crusher cutter are rotated together with a crusher cutter rotated by a motor And the tree branches are broken through the blade portion.

Such a crusher can not reach the position of the desired tree branch, and since the tree branches cut by the worker must be moved and cut, the worker's labor force is still burdened, and the crusher has a problem in that the cylindrical crusher is rotated It can also be seen that the manner of operation is also different from the present invention.

Japanese Patent Laid-Open No. 10-1141540 (Patent Document 3) discloses a technique for adjusting the clearance of a jaw crusher. The first and second clearance adjusting devices provided between the first and second crusher jaws Thereby facilitating the gap adjustment operation and preventing the foreign matter jamming and jaw movement caused during the cutting or crushing operation.

Such a jaw crusher is used for cutting and crushing but it is different from the purpose and effect of the present invention because it is a technique which focuses on the jamming of foreign matter caused by the crushing operation or the jigging of the jaw or the gap between the crusher jaws.

In the waste cutting machine, a blade is formed on both sides of the fixed frame jaw, and a blade and a blade are formed on both sides of the rotating frame jaw, so that the rotating frame rotates, Is configured to cut soft waste at the same size between the blade and the blade of the jaws on both sides of the fixed frame while crossing both the blades and the blades of the fixed frame jaw.

The above-described cutting machine is a technology that is used for cutting soft wastes, and is used only for cutting, and has limitations in use for applications required in various construction works. In other words, it is not suitable for the cutting application of a large solid (rock, concrete lump) and is also unsuitable for transportation.
