Description

Technical Field [0001] The present invention relates to a grinding apparatus for grinding a skid loader,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skid loader-type grinding apparatus, and more particularly, to a skid loader-type grinding apparatus capable of improving a structure of a grinding apparatus to polish a bottom surface at a constant height in polishing a curved bottom surface.

A conventional skid loader-connected grinder comprises a boom which is formed on both sides of a driver's seat where a hydraulic connection jack is formed on one side and is lifted and lowered by hydraulic pressure, and a boom plate which is formed on the side of the boom and to which various auxiliary devices are connected. And a vertical support bar having an upper end and a lower end fixed to the fixing pieces formed on the front surface of the frame, respectively, A support bar including a horizontal support bar extending horizontally at a lower portion of the vertical support bar, and a link connecting a horizontal support bar of the support bar and a front surface of the frame; A cover which is formed on the upper surface of the hollow support member and has an inner hollow portion and an open lower portion so that a side of the horizontal support bar constituting the support bar of the support member is inserted and fixed; A rotating body fixed to an upper surface of a support means formed on an upper surface of the cover and connected to the hydraulic connection jack by a hydraulic hose and a first coupler shrouded in a motor shaft of the motor; A second coupler having an upper end connected to a lower end of the first coupler of the rotary body and a first flange formed at a lower end thereof, and a second flange coupled to a first flange formed at a lower end of the second coupler, And a second joint connected to the first joint of the third coupler is formed on an upper surface of the third coupler, and a bolt And a grinding plate having an additive structure and having a grinding blade projecting from the lower end thereof.

Such a conventional skid loader-connected grinder passes through a curved bottom surface. At this time, since the rotary plate is moved over the curved bottom surface by the buffer spring, the grinder is polished by the grinding blade, In particular, the buffer springs are momentarily contracted at the highest point of the curved bottom surface, and the buffer springs are instantaneously expanded in the process of passing through the peak of the curved bottom surface, thereby forming grooves on the flat bottom surface.

Further, when the bottom surface is shaved to a certain height as the shrinkage and expansion of the buffer spring are constant, a mechanical load due to the grinding blade is generated.
