The present invention installs a soundproof ring surrounding the rod to the lower side of the housing of the breaker mounted on the excavator, and a soundproof plate is installed on the inner circumferential surface of the housing, so that the severe vibration and noise generated by the rod hit by the cylinder of the breaker The present invention relates to an apparatus for preventing vibration and noise of a breaker that can effectively attenuate. In particular, a stepped portion having a recess formed therein is provided below the housing of the breaker mounted on an excavator, and an elastic notched groove on one side inside the groove of the stepped portion. The formed sound-proof ring is interpolated to keep the airtight in a state surrounding the rod, the soundproof plate is installed on the inner circumferential surface of the housing, while on one side of the outer surface of the breaker, the breakdown window is opened as a coupling bolt to open the breaker. Removably installed, breaker cylinder Maintain airtightness through the sound-proof ring when the rod is moved up and down, thereby effectively attenuating the extreme vibration and noise generated by the impact of the rod, as well as by the soundproof plate installed on the inner peripheral surface of the breaker housing To reduce the vibration of the breaker to extend its life, and to open the disassembly window installed on one side of the outer surface of the breaker, the breaker vibration and noise prevention device for easy and easy maintenance inside the breaker.

In general, the breaker which is connected to the arm of the boom end of the excavator and performs various civil works, as shown in Figure 1, the noise and vibration caused by the impact of the cylinder and the struck rod during the operation such as the excavation light by hydraulic It is an extreme occurrence.

The noise prevention structure of a conventional breaker associated with such a technique is known from Korean Patent Publication No. 10-0529508.

That is, the technical configuration is as shown in Fig. 2, the breaker is provided with a cylinder (1) and a piston (2) operated by hydraulic or pneumatic, and hitting the piston (2) in front of the cylinder (1) The rod 3 is provided, while the rod 3 has a sharp tip to break or break a building or road, and a housing for connecting the arm of the excavator to the front and the rear of the cylinder 1. (4) is provided, in order to absorb the noise generated during operation of the breaker rod (3) inside the housing (4), a plurality of flaw plate 16 is installed inside the side plate 11 and the top plate ( 12) and the bottom plate 13 is wrapped and fixed, and the space portion formed inside the piston (2) is made of a configuration in which the absorber 17 for absorbing a separate blow noise is embedded.

In the conventional breaker noise prevention structure having the above configuration, the rod 3 is repeatedly hitting an object by the cylinder 1 and the piston 2 extended, and the rod 3 The noise generated by the striking) is absorbed through the sound absorbing plate 16 inside the housing 4, and the striking noise is absorbed through the absorber 17 inside the piston 2.

However, since the extreme noise and vibration generated when the rod 3 operated by the cylinder of the breaker is hit by the vertical movement is transmitted to the breaker through the gap between the rod 3 and the lower end of the housing, the housing The lower end is extremely vulnerable to the vibration caused by the strike, accordingly, it is not possible to properly absorb the vibration transmitted to the breaker, as well as the shortcomings of shortening the life of the breaker.

In addition, when opening for maintenance of the power transmission system of the breaker housing, there were many problems such as extremely deterioration of workability by disassembling and assembling the whole housing.

The present invention has been made in order to improve the above-mentioned conventional problems, the object of which is to maintain the airtight through the sound-proof ring during the vertical movement of the rod actuated by the cylinder of the breaker, according to the extreme caused by the impact of the rod In addition to effectively attenuating vibration and noise, the soundproof plate installed on the inner circumferential surface of the breaker housing reduces the vibration of the breaker and extends its life, and opens the disassembly window installed on one side of the outer surface of the breaker. An object of the present invention is to provide a breaker vibration and noise prevention device that can easily and easily maintain a breaker interior.

As a technical means for achieving the above object, the present invention, in the breaker having a cylinder and a piston in the housing of the breaker which is operated by hydraulic or pneumatic, and the front of the cylinder is provided with a rod striking the piston ,

A stepped portion integrally installed with a recess formed inside the housing of the breaker mounted to the excavator;

Upper and lower sound insulation rings are formed in the grooves inside the stepped portions, respectively, and elastic cutout grooves are formed at one side, and a plurality of hemispherical grooves are formed at the periphery so as to insert the interpolation to maintain airtightness in a state surrounding the rod;

Seal parts installed on the upper and lower sound-proof ring peripheral part so that the upper, lower sound-proof ring to be inserted into the groove in the step portion is fixed tightly;

A resin soundproof plate installed on an inner circumferential surface of the housing; And

By virtue of providing a vibration and noise prevention device of the breaker, characterized in that it comprises a; a disassembly window is installed to be detachably as a coupling bolt to open the interior of the breaker to one side of the outer surface of the breaker.

At this time, the soundproof ring installed inside the groove formed in the lower step portion of the housing is made of a urethane resin, wherein the lower soundproof ring is characterized in that the inclined portion is inclined in the inner peripheral surface so that the upper soundproof ring is installed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
