BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-purpose attachment for heavy equipment, and relates to a multi-purpose attachment for heavy equipment capable of performing work by converting it into a bucket or grab form according to a work purpose.

In general, the excavator used in the construction site, the excavation of the ground using the bucket (bucket), the loading and transport of the earth and sand, the crushing and reinforcing of the building using the crusher (crusher), the rock using the breaker (Breaker) and Various kinds of attachments can be exchanged with each other depending on the purpose, such as concrete demolition work and heavy material transport work such as scrap and rock using grabs.

On the other hand, various types of attachments are detachably mounted to the arms of the excavator so that they can be replaced according to the purpose of the work.

An example of mounting this attachment to an excavator is shown in FIGS. 1 and 2. 1 shows a state in which the bucket 10 is mounted to the excavator arm 1 by an attachment coupling 4, the attachment coupling 4 having the bucket 10 attached to the arm 1 of the excavator. It is configured to connect easily.

Here, the first and second bucket mounting pins 31 and 32 are installed on the bucket 10. First, the fixing hook 21 of the attachment coupling 4 is fixed to the first bucket mounting pin. And insert the bucket 10 into the second bucket mounting pin 32 by rotating the driving hook 22.

The bucket 10 attached to the attachment coupling 4 is mainly used for the purpose of loading and transporting the excavation of the ground or earth and sand, but depending on the situation, it is also used to carry scrap metal, rock and wood.

However, when the bucket 10 is used for carrying heavy materials such as rocks and wood, there is a problem that the work efficiency is significantly lowered and the risk of an accident is increased. This is because the structure of the bucket 10 is suitable for the purpose of pumping up and transporting soil and relatively small particles of rock, so that it is not easy to carry rocks larger than the weight of the heavy material accommodated in the bucket 10 and the like. This is because heavy articles of the same length must be placed on the bucket 10 and bundled in a rope.

2 and 3 are perspective views showing a state in which the grab 35 is fitted to the attachment coupling 4 provided on the arm 1 and a conventional bucket-type tongs for heavy equipment. The mounting method of the grab 35 is the same as the mounting method of the bucket 10, and the grab 35 is operated by the driving hook 22 installed on the arm 1.

An excavator equipped with such a grab 35 has a problem in that it is not suitable when it is intended to be used for the purpose of loading and transporting ground excavation and earth and sand.

The present invention is to solve the problems as described above, according to the work purpose bucket function for loading and transporting excavation or soil excavation without replacing the bucket or grab, and easy to transport heavy materials such as wood or large grain stone The purpose is to provide a multi-purpose attachment for heavy equipment that can perform one grab function at the same time.

In addition, an object of the present invention is to provide a multi-purpose attachment for heavy equipment that can easily transport wood and large stones when used as a grab.

In order to achieve the above object, the present invention, the attachment coupling (Attachment Coupling) for connecting the arm (Arm) and the push link (Push Link) of the heavy equipment, and in the attachment mounted on the heavy equipment by the attachment coupling The attachment includes a bucket mounting portion having a bucket provided with a bucket tooth and installed in the bucket and mounted to the attachment coupling; It is characterized in that it comprises a jaw is hinged rotatably coupled to the bucket mounting portion, the jaw tooth (Jaw Tooth) is engaged with the bucket tooth, the excavation tooth is installed on the other side of the jaw tooth. .

In addition, the jaw, and a pair of side plates that are spaced apart; First and second plates arranged at intervals above the side plate; A second cylinder coupling hole penetrating through the side plate and the first and second partition plates, through which a jaw coupling hole of the drive cylinder is penetrated by a second cylinder coupling pin; A support shaft for supporting the side plate and the first and second partition plates; The base plate is installed on the lower side of the support shaft and connects the pair of side plates, and the jaw tooth and the excavation tooth are installed to face each other in a direction perpendicular to the connected portion.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the multipurpose attachment for heavy equipment according to the present invention will be described in detail.
