With this configuration, the lower end of the shank 30 is freely rotated from the oscillating body 20 by the first link 50, which interferes with a proper ripping operation.
As shown in the figure, the second link 60 is connected to the upper left portion of the shank 30.
The other side of the second link 60 is connected to the front and back wall of the outer case 10 by the second link connection pin 60a so that the shank 30 can be prevented from rotating freely while preventing the free rotation of the shank 30. [ So that it can be moved up and down.
A guide hole 14 for guiding the movement of the shank 30 is formed at a lower portion of the outer case 10 so that the shank 30 can be moved up and down.
The function of the second link 60 is to limit the upward movement of one side of the shank 30, in particular the shank 30, which rotates about one point of the oscillating body 20 by the first link 50, Thereby preventing the shank 30 from rotating freely and enabling the striking to be performed at an accurate point.
In the above configuration, it is preferable that a third link 61 constructed in the same manner as the second link 60 is further provided under the second link 60 as shown in the figure.
The third link 61 is provided below the second link 60 and the third link 61 is also connected to the outer case 10 by the third link connecting pin 61a. .
This is because when the link connecting the outer case 10 and the shank 30 is composed of only one second link 60, the force generated by the upward and downward movement of the shank 30 is dispersed in several places, So as to further reduce transmission to the arm connected to the outer case 10.
Further, even when the shank 30 is moved up and down, more accurate rotation and up-and-down movement can be guided.
5 and 6, a spring 70 is provided between the bottom of the mounting portion 11 of the outer case 10 and the upper portion of the vibrating main body 20 so that the upward centrifugal force So that the thrust can be applied at the same time.
A cushioning member 80 is provided between the inner wall surface of the outer case 10 and the lower portion of the vibration body 20 so that when the vibration body 20 suddenly falls It is preferable to prevent the impact to be applied to the lower portion of the outer case 10.
At this time, the buffer member 80 may be formed of a material such as elastic rubber.
The bottom plate of the outer case 10 may be integrally formed with the outer case 10 but is not suitable for disassembly for maintenance of the product and has a lower fixing plate 13 as shown, (10).
In addition, although the position of the buffer member 80 is not limited to the drawings, it is preferable that the shock transmission to the lower fixing plate 13 is minimized by being located at the mounting position of the lower fixing plate 13.
5 and 6 show an operation state of a shank link rotation type vibration ripper according to the present invention. As the eccentric weight 22 rotates according to the operation of the drive motor 24, ) In the clockwise direction and the counterclockwise direction.
At this time, the shank 30 rotates about the one point of the oscillating body 20 by the first link 50, and the second link 60 and the third link 61 rotate the outer case 10, As shown in FIG.
Accordingly, when the oscillating body 20 is rotated in the counterclockwise direction as shown in FIG. 6 at the position shown in FIG. 5, the shank 30 moves upward by the guide of three links, and moves downward in the opposite direction.
As the shank 30 is separated from the vibrating main body 20 separately, the shank 30 shows a lighter movement.
Also, as the shank 30 is connected by the rotating multiple links, the transmission of vibration and impact is minimized.
