Claims

[Scope of Claim for Utility Model Registration] (1) A snow removal blade consisting of a central blade with wing plates connected to the left and right sides of the central blade is attached to the front part of the vehicle body, and the snow removal blade is installed inside the driver's cab in the vehicle body and is attached to the upper end of the rod. It has a control lever that has an operating grip that extends in the transverse direction and is capable of tilting in each direction and rotating the operating grip around the axis of the rod. In response to various operations by pressing the switch provided on the surface of the operating and operating grip, the snow removal blade moves up and down, tilts left and right, swings left and right, swings up and down, and opens and closes the blades. In the operating device for a snow removal blade with wing plate of a ski slope maintenance vehicle, the operating grip is provided with a push-type switch, and the operating lever is tilted and the grip is rotated without pushing the push-type switch. The snow removal blade is raised and lowered, tilted left and right, pivoted left and right, and pivoted up and down in response to the pressing operation of the seesaw switch, and the operation lever is tilted by pushing the push-in switch; A snow removal blade operating device characterized in that the opening and closing operations of both side wing plates of the snow removal blade are performed in various manners in response to the rotating operation of the grip and the pressing operation of the seesaw switch. (2) The snow removal for the ski slope maintenance vehicle according to claim 1, wherein the seesaw switch is provided vertically on the side surface where the thumb touches when the operating grip of the operating lever is grasped for operation. Blade operating device. (3) The above operating lever is provided so that it can be tilted back and forth in any direction 360 degrees around the axis, and the operating lever can be tilted back and forth, left and right,
The left and right rotation of the grip, the lifting and lowering of the snow removal blade in response to the press of the seesaw switch, the left and right tilting, the left and right swing rotation, and the up and down swing rotation can be performed simultaneously by combining the corresponding operations. The operating device for a snow removal blade of a ski slope maintenance vehicle according to claim 1.
