The present invention enables a standard function of the ripper and a function of tongs to be achieved by one ripper in order to perform works using the ripper and the tongs while only the ripper and main pieces of the tongs are mounted in the ripper without alternately replacing each bucket and the ripper while performing the works. Therefore, the present invention can removes in convenience and degradation of work efficiency caused by repetitive replacement and installation of the bucket.

Description

[0001] The present invention relates to a multi-function ripper for an excavator having both a tongue function and a ripper function,

The present invention relates to a multifunctional ripper which is installed on a boom of an excavator and is used for breaking off an obstacle such as an ascon of the ground and is usually mounted on a boom instead of a bucket so as to exhibit a basic function of a ripper, It is possible to change the structure of the bucket without changing the structure of the bucket. Therefore, it is possible to eliminate the burden of replacing the bucket at the same time and to improve the work efficiency This is a technology that can be improved.

Generally, an excavator mainly carries out work such as digging soil on the ground by using a bucket installed on the boom.

In addition to these main tasks, it is also possible to move rocks or other heavy obstacles existing on the ground of the workshop.

In this case, the main bucket is mounted on the back of the boom while the bucket is basically installed. The bucket and the main bucket are rotated in opposite directions through the cylinder in a state where the main bucket and the bucket face each other. So that the bucket and the main forceps can exhibit a single clamping function,

In this state, a tongue function in which an obstacle such as a rock is picked up between the bucket and the main forceps is exerted.

Recently, in order to exercise such a tongue function at any time, it is basically equipped with a main tongs always attached to the boom. Normally, when a tongue is required to work by using only a bucket, the main tongs are operated immediately, .

In addition to these tongs,

If you need to remove asphalt or cement from the work site during the work process, remove the bucket from the boom bar and replace it with a separate device called 'ripper'. Then, the ripper is rotated by the cylinder, And the like.

However, if you perform the work with the ripper installed instead of the bucket, and you need to use the tongue to lift the obstacles on the ground, remove the used ripper from the boom frame and remove the bucket It should be mounted on the boom again so that it can be used with the main forceps.

After that, to use the ripper again, remove the bucket and re-install the ripper.

In other words, since a conventional ripper has to exert pure ripper function, it is troublesome to install a bucket and a ripper alternately in order to perform a ripper operation and a tongue operation at the same time. In addition, There is a high possibility of safety accidents during the replacement process.

And for reference, buckets or rippers separated from the boom frame must be located at a point away from the work point for operational safety reasons,

Whenever the bucket and the ripper are changed every so often, the whole excavator has to travel between the beach point and the work point every time, which leads to a decrease in the efficiency of operation and a waste of fuel.

Since the bucket is used both for the work of the excavator and the work for the bucket, the bucket is likely to wear and break, and the bucket is the main work tool of the excavator. Therefore, the economical burden and time burden none.

Disclosure of the Invention The present invention has been made to solve the above problems of the prior art,

One ripper can be operated simultaneously with the ripper basic function and the tongue function, so that when the tongue work and the ripper work are carried out from time to time, the ripper operation and the main tongue operation can be performed without replacing the bucket and the ripper one by one. As well as the pinched operation can be carried out, it is possible to eliminate the troubles due to repetitive replacement of the bucket and the phenomenon that the work efficiency is lowered.

The present invention for solving such a problem,

A ripper rotatably connected to a main link of an end of a boom with a main clamp plate mounted on a back of an excavator boom,

A fixing body connected to the main link and having an upper end integrally fixed to a lower end of the coupling portion, a first central shaft hole formed at a center of a lower end thereof, and a first coupling hole formed at a first central shaft hole, And a second central shaft hole is formed at the center point and the second central shaft hole is positioned so as to be in line with the first central shaft hole and is symmetrical with respect to the first central shaft hole, A coupling plate having a second coupling hole formed therein and pivotable about an axis pin passing through the first and second central shaft holes at the same time, a ripple tooth protruding from one side edge of the coupling plate, A foldable reef piece extending from a point symmetrical to the reed piece about the connecting plate, The ripper is a larger number of teeth than the teeth tongs connected with the right and left distance and rotating operation body, including the connecting plate and the rotatable clamp pieces together,

And a rotation blocking pin inserted into the first and second fastening holes so as to penetrate the first and second fastening holes at the same time in a state where the rotation operation body rotates around the fastening pin to block the rotation of the rotation operation body .

In addition, the fixing body is formed with an insertion gap at a dividing point in a state where the lower end is divided into two, and the first central shaft hole and the first fastening hole are formed to face each other at mutually symmetric points with reference to the dividing point, Wherein the pivoting operation body is inserted into the insertion gap so that the second center shaft hole is positioned so as to be in line with the first center shaft hole and the shaft pin passes through both the first center shaft hole and the second center shaft hole at the same time, And the pivot pin is pivoted about the pivot pin, and the pivot pin and the pivot pin protrude from both sides of the lower end of the fixed body. When the pivot pin is completely pivoted in one direction in the course of pivoting with the pivot pin, The end portion is brought into contact with the one side edge of the fixed body so that the further rotation is blocked and the other end is completely rotated The end portion of the pincers comes into contact with the other side edge of the fixed body and is no longer rotated.

And a first insertion groove through which the ripple teeth can be inserted in the process of the rotation of the rotary operation body among the rims of the fixed body and the ripples of the ripper pieces contacting the fixed body, A second insertion groove into which the pawl teeth can be inserted is formed in the process of contacting the pawl body with the pawl body.

The side surfaces of the reamers facing each other in a state where the reamers are positioned on both sides with respect to the end of the reamer piece are integrally connected to both sides of the reamer piece. As shown in FIG.

According to the present invention,

If you want to use the ripper function instead of the bucket, attach the ripper to the main link of the boom. Rotate the entire body so that the ripper and ripper teeth face the ground. To do this,

In this state, when it is desired to exhibit the tongue function,

After replacing the buckets, place the entire ripper on the ground, remove it from the main link, lift it up again in the opposite direction from the main link, rejoin the main link, remove the pivot pin, So that the clamping pieces and the main clamp pieces face each other in a state where the clamp pieces and the clamp teeth are directed to the ground and then the pivot pin is re-joined again.

Therefore, when the ripper operation is switched to the clamping operation, the clamping function of the ripper can be exerted only through the rotation of the rotating body of the ripper without the need to re-install the bucket. Therefore, It is possible to solve the troublesome work and improve the work efficiency.

In addition, the moving distance and time of the excavator for frequent replacement of the bucket and the ripper can be reduced, thereby improving the working efficiency and reducing the fuel consumption.

Also, not using the buckets for clamping purposes minimizes wear and tear on the buckets, thus extending the life of the buckets.
