Description

[Detailed description of the invention] Tire chains often fall off on snow-covered roads and highways due to the high speeds of general vehicles.

As is well known, snow removal from snow-covered roads is often carried out using plow snow blowers and rotary snow blowers, and therefore tire chains that can fall off often lead to damage to the machinery.

The present invention is intended to prevent damage to this machine, and the details of one embodiment of the present invention will be described below with reference to the drawings.

A is a foreign object capturing device such as a tire chain according to the present invention.

The configuration is such that a catching device 3 is provided in front of the rotary snow removing device 2 in a general rotary snow removing vehicle consisting of a rotary snow removing vehicle 1 and a rotary snow removing device 2, and the catching device 3 is arranged in the direction of movement of the rotary snow removing device. supports a shaft 4 rotatably in orthogonal directions, an appropriate number of blades 5 are vertically attached to the shaft, and an appropriate number of catching hooks 6 are attached to the tool 5.

In place of the wings 5, an appropriate number of arms 7 are installed vertically on the shaft 4 in a staggered manner, and a hook-shaped catching notch 7A is provided at the upper end of the surface of the arms 7 in the direction of rotation. It may be engraved.

The gap between the tool 5 or the arm 7 is such that it is necessary to capture the tire chain.

Further, the shaft 4 may be driven from the snow removal device 2 by a chain 8 or the like as shown in the figure, or may be rotated using the hydraulic power source of the snow removal vehicle 1, etc., depending on the design. Although it is input on the left side of 4, it is natural that the scale changes to the right side.

Furthermore, the capture hook 6 attached to the tool 5 is
In order to minimize resistance to snow during installation, the direction in which the snow flows on the surface of the tool 5 is the same as the longitudinal direction of the hook 6, and the V-shaped opening 6A of the catching hook 6 is Install it facing away from the snow flow.

Naturally, this also applies to the arm 7 described above.

Further, the method of attaching the catching hook 6 or the arm 1 may be changed as appropriate, such as attaching with bolts, nuts, or welding.

Since the proposed device is constructed as described above, the tire chain that has fallen into the snow can be caught by the hook 6 on the rotating wing.
Alternatively, it is reliably captured by the capture notch 7A of the arm 7.

As a result, this is a useful device that can prevent foreign objects such as tire chains from entering the rotary snow removal device 2 as pointed out at the beginning, and prevent damage to the machine.
