Description
The present invention relates to a vibration ripper installed in a heavy equipment, in which a rotary shaft connecting an outer case and a vibration main body is installed on one side so that the vibration main body rotates about a rotary shaft, and the vibration main body and the shank are separated from each other And a shank link rotating type vibration ripper which has a light up and down movement by linking the vibrating main body, the shank, the shank and the outer case with each other so as to minimize unnecessary lateral vibration caused by the movement of the boom or the arm.
Generally, excavators used in civil engineering and construction sites for the development of highways, harbors, bridges, dams, buildings, and cities are used to perform the compaction, crushing, excavation, etc. of ground by batting operation, rotation operation and drilling operation A severe noise is generated.
Especially, excavation of rocks, concrete structures, solid ground, etc., or use of a breaker or ripper mounted on a boom of an excavator in order to scrape the soil of the ground. The vibration generated by a breaker or a ripper is directly transmitted to the boom. The vibration generates noise and damages the boom.
In view of this, a "nipper for an excavator" (Korean Patent Registration No. 10-0741245, Patent Document 1) includes a connection mount portion fixedly connected to a boom of an excavator, a connection mount portion rotatably mounted on the connection mount portion, A blade main body for excavating the soil, and a vibration means mounted on the blade main body for providing a vibration force to the blade main body.
In the nipper for an excavator in Patent Document 1, a blade body is rotatably mounted on a boom of an excavator, and vibration is provided to the blade body, so that vibration is transmitted to the boom through the blade body. Thus, The vibration is amplified to make the adjustment of the excavator difficult, and further, the excavator is damaged.
On the other hand, in the "Vibration Ripper for Excavator" (Korean Patent Laid-Open Publication No. 10-2012-0125916, Patent Document 2), there is provided an operation plate inside the housing and a drive unit for camming the operation plate, A damper for connecting the upper and lower portions to the upper portion of the housing and a link for connecting the damper are provided to restrict forward movement during camming.
In the above configuration, the operation plate installed inside the housing is configured to only move up and down, and the dampers connected to the operation plate absorb the forward and backward movement moments. Bolted to move up and down along the operating plate.
However, in the above-described structure, the dampers for restricting the movement of the actuating plate to be rotated are heavily loaded, and the durability of the damper and the actuating plate is deteriorated.
In addition, since the ripper is also integrally connected to the operation plate, vibration is transmitted even to the ripper blade.
In addition, in the process of moving the boom or arm, there is no intervening component to block or reduce the vibration in the left and right direction that occurs outside the vertical direction, so that vibration is directly transmitted to the boom or arm, And noise generation can not be minimized.
The shank link rotation type vibration ripper of the present invention is provided to solve the problems caused by the conventional art as described above. The vibration ripper of the present invention is configured such that a rotary shaft connecting the outer case and the vibration body is installed at one side, In addition, the vibration body and the shank are separated from each other, and the vibrating body, the shank, the shank, and the outer case are connected by a link so as to minimize the unnecessary lateral vibration due to the movement of the boom and the arm I want to.
More specifically, the oscillating body is configured to be rotatable from the outer case with respect to the rotating shaft, and the shank is rotatably connected to the oscillating body, so that the oscillating body is conventionally moved up and down, So that the movement of the shank can be moved much more lightly by the way it moves.
Further, since one side of the shank is linked to the vibrating main body and the other side is linked to the outer case in a linking manner, the up and down movement of the shank is controlled to prevent the rotation of the shank, I would like to.
In addition, when a spring is installed on the upper part between the outer case and the vibrating main body, and the cushioning member is installed between the outer case and the lower part of the vibrating main body, In order to minimize the possibility of adding.
In order to solve the above-mentioned problems, the vibration ripper of the shank link rotation type of the present invention includes an outer case having a mounting portion for engaging with a boom or a heavy equipment fixing bracket on an upper side thereof, And a pair of rotation shafts disposed in parallel to each other and provided with eccentricities on the rotation shafts, respectively, a drive gear provided on the rotation shafts and meshed with each other such that the pair of rotation shafts rotate in opposite directions, A vibrating body connected to one rotary shaft and having a driving motor for rotating the rotary shaft, and a vibration ripper having a shank at a lower portion of the vibrating body, wherein both end portions are fixed to the front and back wall of the outer case Wherein the rotary shaft is passed through a vibration body inside the outer case And the shank and the vibrating main body are separated from each other. The first link is connected to the shank and the vibrating main body, and the first link is connected to the shank and the vibrating main body. And a second link is connected to an upper left portion of the shank, and the second link is connected to a front surface and a rear wall of the outer case by a second link connecting pin, And a guide hole for guiding the movement of the shank is formed in a lower portion of the outer case.
In this case, a third link formed in the same manner as the second link is further provided below the second link.
In addition, a spring is provided between the bottom of the mount portion of the outer case and the upper portion of the vibrating main body.
Further, a buffer member is provided between the inner wall surface of the outer case and the lower portion of the vibration body.
According to the present invention, the vibration body is configured to rotate with respect to the rotation axis by disposing a rotary shaft connecting the outer case and the vibration body on one side, and the vibration body and the shank are separated from each other and the vibration body, the shank, By connecting the outer case to each link, unnecessary lateral vibration due to the movement of the boom or arm can be minimized while having a light up and down movement.
More specifically, the oscillating body is configured to be rotatable from the outer case with respect to the rotating shaft, and the shank is rotatably connected to the oscillating body, so that the oscillating body is conventionally moved up and down, The movement of the shank can be moved much more lightly by the method of moving.
Further, since one side of the shank is linked to the vibrating main body and the other side is linked to the outer case in a linking manner, the up and down movement of the shank is controlled to prevent the rotation of the shank, .
In addition, when a spring is installed on the upper part between the outer case and the vibrating main body, and the cushioning member is installed between the outer case and the lower part of the vibrating main body, Can be minimized.
