Abstract
The present invention relates to a quick coupler for excavator for manually coupling or separating work tools according to the nature of the work is coupled to the construction, civil machinery, such as excavator.
Conventionally, the hydraulic pressure is actuated to operate the movable hook to engage or separate the work tool, but this is a means of operating the movable hook by means of a cylinder actuated by the action of hydraulic pressure. The need for a hydraulic line for supplying the device is complicated and the cost is increased. To solve this problem, a pair of coupling pins coupled to the arm of the excavator is provided on the upper side, and a lower side of the work tool is provided. In the quick coupler for excavator is provided with a fixed hook is inserted into one side of the fixing pin and the other side movable hook receiving elastic force by the elastic member to the hinge pin, the movable hook 40 is provided with a support plate spaced apart A hinge portion 41 coupled to the hinge pin 36 coupled to the 31 and 32, and the rear surface of the movable hook 40 Safety pin 37 is inserted into the side, the front side is characterized in that the locking bolt 43 is detachably fastened by penetrating the locking plate 46 to the boss 44 coupled to the front of the movable hook 40. A quick coupler for an excavator is provided.
Therefore, by operating the movable hook manually, the structure is simplified, the manufacturing is easy and the operation is assured, and the manufacturing cost is low. In particular, the coating is performed on the back and front sides of the movable hook, so that the movable hook is not detached arbitrarily. Will have

Description
The present invention relates to a quick coupler for an excavator, and more particularly to an excavator quick coupler for easily coupling and separating the brake, crusher, bucket, etc. manually to heavy equipment such as excavators.
In general, in the construction of excavators and heavy equipment for civil engineering, work tools such as breakers, buckets, and crushers are used to dig the ground, treat the soil dug from the ground, or crush rocks. It will be replaced according to the work.
Conventionally, a device for coupling a work tool is coupled to the
And the
Therefore, the
However, such a conventional technique is a means for operating the movable hook is made by a cylinder that is operated by the action of hydraulic pressure, but there is a convenience that can be coupled or detached work tools in the driver's seat, but supply the hydraulic pressure to the cylinder inside the coupler The need for a hydraulic line for this has caused problems such as complicated apparatus and increased cost.
The present invention has been invented to solve the above problems, an object of the present invention is to provide a quick coupler for excavators that is simple in structure, easy to operate, reliable operation and can reduce the manufacturing cost.
Excavator quick coupler according to the present invention for achieving the above object is provided with a pair of coupling pins coupled to the female arm of the excavator on the upper side, a fixed hook is inserted into one side fixed pin of the working mechanism on the lower side In this provided and the other side of the quick coupler coupled to the movable hook that is elastically coupled to the hinge pin by the elastic member, the movable hook includes a hinge portion coupled to the hinge pin coupled to the support plate installed at intervals And, the safety pin is inserted into the back side of the movable hook, the front side is characterized in that the locking bolt is detachably fastened through the locking plate to the boss coupled to the front of the movable hook.
According to the present invention, by operating the movable hook by manual rather than hydraulic type, the structure is simplified, the manufacturing is easy and the operation is made reliably, and the manufacturing cost is low. In particular, the coating is performed on the back and front sides of the movable hook. It has the effect of having the safety that a hook does not separate.
Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
