Abstract: The present invention relates to construction machinery, and relates in particular to an operation device of a skid-steer loader, and a skid-steer loader. The operation device of a skid-steer loader can be disposed on a frame structure (3) of the skid-steer loader, and is located on a side of an operator cab (5) of the skid-steer loader. The operation device comprises a lift arm (16) comprising a clearance section (10). When the lift arm (16) is in a traveling position, the clearance section (10) is located in a region of the lift arm (16) adjacent to a side window of the operator cab. A top portion of the clearance section (10) is recessed toward a bottom portion of the frame structure (3) of the skid-steer loader. The operation device of the skid-steer loader can reduce the area on the side of the operator cab blocked by the lift arm, thereby increasing the peripheral vision of a driver.

Abstract: A Block-Type structured diamond grinding wheel with adaptive supply of instantaneous Cooling, includes a grinding wheel substrate and several grinding wheel units, each including an execution mechanism, a push mechanism, and an instantaneous Cooling mechanism. Various structured patterns are provided on an upper surface of the grinding unit in the execution mechanism, and a heat sink is disposed at a lower surface. During operation, a tangential grinding force generated by the grinding unit and a workpiece presses a sprayer to spray nano fluid into an operating region, to implement instantaneous Cooling of grinding wheel. When wear occurs in a grinding unit of a grinding wheel, a corresponding grinding unit may be replaced to extend the service life of the grinding wheel, and production costs are reduced. A special surface structure of the grinding unit further enhances a cooling effect, thereby improving a surface quality of a workpiece.
