Description

Description: TECHNICAL FIELD The present invention relates to a road surface ice cutter for cutting ice snow accumulated on a road surface into a groove shape.

(Problems of the invention and its characteristic points) In the snowy country, in early spring, ice and snow accumulates high on the road surface along with dust, which obstructs the flow of snow melt water toward the manhole, and the snow melt water stagnates on the road surface. The phenomenon described above occurs, which is an obstacle to road surface traffic, and in the past, a great deal of human power was required to cut the ice and snow into grooves to form a running water channel.

The present invention is intended to provide a road surface ice cutter that can easily perform the above-mentioned work, and the structural features thereof are as described in the claims.

The road ice cutter of the present invention is attached to one side of a work vehicle such as a snowplow, and at the time of work, the first arm is tilted to the side, and the first arm is rotated while rotating the cutter shaft at the tip of the second arm. The arm is gradually extended, and the ice and snow accumulated on the road surface is cut toward the manhole in a groove shape to form a running water channel.

(Detailed Description of the Invention According to the Drawings) In the drawings showing an embodiment of the present invention, reference numeral 1 is a snow plow, a rotary snow removing device 2 is provided in a front portion thereof, and a road surface ice cutter 3 of the present invention is provided on one side thereof. Are attached via a mounting frame 4.

The first arm 5 of the road surface ice cutter 3 has its base end pivotally supported by the mounting frame 4, is tiltable in the left-right direction of the snow removal vehicle 1, and is telescopically expandable. Cylinders 6 and 7 are provided for tilting and stretching.

A rear end of a second arm 9 extending in front of the first arm 5 is axially attached to a tip end of a slide arm 8 which is a telescopic part of the first arm 5, and the second arm 9 is operated by a cylinder 10 to move the first end. The one arm 5 is slightly rotated in the same direction as the up and down direction.

A cutter shaft 11 is attached to a tip end portion of the second arm 9, and the cutter shaft 11 is oriented so that the second arm 9 is oriented vertically when the first arm 5 is tilted to the side.
And is supported by bearings 12 and 12, the rotation of which is
The operation of the hydraulic motor 13 installed on the second arm 9 causes the second
It is designed to be carried out via a chain transmission mechanism 14 provided inside the arm 9.

A large number of disk-shaped cutter mounts 15 are mounted side by side on the cutter shaft 11 in the lengthwise direction, and a large number of cutters 16 are provided on each cutter mount 15 so as to project in the radial direction. Further, a sliding seat plate 18 is attached to the road surface contacting end of the cutter shaft 11 via a bearing 17, and this slides on the road surface during the work of forming a running water channel to maintain the working height of the road surface ice cutter 3. And, it helps to stabilize the road ice cutter 3.

Reference numeral 19 denotes a snow cover provided at the tip of the second arm 9.

When the road ice cutter 3 is not used, the first arm 5 is erected so as to be in a folded state shown by a chain line in FIG.
In the state shown by the solid line in the figure, while rotating the cutter shaft 11, the first arm 5 is gradually extended toward the manhole, and the accumulation layer of ice and snow lying between the stagnant portion of the snow melt and the manhole is grooved. Cut into a shape to form a running channel.

(Effects of the Invention) Since the road surface ice cutter of the present invention is as described above, the above-described flow channel forming work, which conventionally relies on human power, can be easily and easily performed with mechanical power, and labor saving is achieved. Can be expected.

Claims (1)

(57) [Claims] 1. A telescopic part of a telescopic first arm which is attached to one side of a work vehicle such as a snow blower so as to be able to move up and down.
A rear end of a second arm extending forward of the arm is pivotally attached, and a cutter shaft is attached to a tip end portion of the second arm so as to be vertically oriented in a state where the first arm is laid sideways. The road ice cutter is characterized in that a number of cutter layers are arranged side by side in the lengthwise direction, and a sliding seat plate is attached to the road contact end.
