Description

[Detailed explanation of the invention] A. Purpose of the invention a. Industrial application field This invention is a brush-type snow removal device for removing snow from roads. The object is to provide a deflector that prevents splashing.

b. Conventional technology and its problems Traditionally, brush-type snow removal devices have been used only at airports, so their purpose is to blow snow away far away, and devices to prevent snow from falling on other passing vehicles or people have been used. Not prepared.

B. Structure of the invention a Means for solving the problem A brush-type snow removal device uses a brush planted in a cylindrical shape, laid on its side, and placed diagonally in front of the snowplow with the left side set back. By rotating the device upward so as to knock it off, fresh snow on the road surface is thrown diagonally forward, and the device is moved forward continuously to remove snow.

Since the cylindrical brush rotates at the same speed over its entire length, the snow thrown off from the brush is spread over the entire length of the brush at the same distance.

Normally, when snow is removed from a road, snow is sent to the left one after another and eventually accumulates between the sidewalk and the roadway. It is desirable to avoid blowing snow away from the right side of the snow removal equipment, and not to blow it too much from the left side. Or, when people are present and should not splash on snow, it is necessary to instantly restrict snow removal.

The present invention solves the above problem by providing a deflector, either integrated or divided into several pieces, in front of the brush-type snow removal device so that it can be opened and closed using a linear actuator such as a hydraulic, pneumatic or electric cylinder.

b Example of the invention Figure 1 shows an example of the invention, where 1 is a brush, 2
is a deflector, which is attached to the brush frame 8 by a hinge 3, and is configured so that the deflector 2 can be opened and closed by extending and contracting the hydraulic cylinder 4.
5 and 6 are snow blown away by the brush-type snow removing device, and L5 and L6 are snow removal distances.

The detailed configuration is as shown on the left: A brush 1 that rotates clockwise when viewed from the left side about an axis perpendicular to the direction of travel of the snow removal vehicle.
, a brush frame 8 that supports the central axis of this brush at both ends, a deflector 2 that is swingably attached to the front of this brush frame with a hinge having the same direction as the brush axis, and this deflector 2 and the brush. A linear actuator that acts in the traveling direction of the snow removal vehicle is installed between the frame 8 and the linear actuator, and by actuating this linear actuator, the swing angle of the deflector is changed so that the deflector covers the front of the brush. It is configured so that it can be varied from the angle to the angle at which the front of the brush is opened.

In addition, in the brush-type snow removal device, the brush 1 is rotated in the direction shown by the arrow D in the direction of movement and splashes snow, and then moved in the direction of F, so that the brush has an angle of θ with the direction of movement. As is well known, the snow on the road surface flies away as shown in Figure 5, and as a result, it becomes possible to remove the snow.

FIG. 2 shows the deflector 2 divided into left and right deflector units 2A and 2B. Since these deflectors 2A and 2B are attached to the brush frame 8 by hinges 3, by expanding and contracting the hydraulic cylinder 4A, the deflectors 2A and 2B can be
A can be opened and closed. Deflector single unit 2B
The deflector unit 2B is also configured to be opened and closed by expanding and contracting the hydraulic cylinder 4B.

c. Effect Explain along with the effects.

C. Effects of the invention The deflector of the brush type snow removal device configured as described above can obtain the following effects.

In FIG. 1, since the brush 1 rotates at the same rotational speed over the entire width W, the snow removal distance L5 from the grounding point P of the brush is uniform over the entire width W.

However, when the rider 7 is on the left side of the brush-type snow removal device as shown in FIGS. 2 and 3, the hydraulic cylinder 4 in FIG. 1 and the hydraulic cylinders 4A and 4B in FIG. 2. By closing the deflectors 2A and 2B, the snow removal distance can be reduced from L5 to L6, making it possible to prevent snow from falling on the pedestrian 7.

In addition, it is possible to prevent the clothes of pedestrians from getting dirty due to splashing muddy water, injury to pedestrians due to flying ice, pebbles, etc., and damage to parked vehicles.

Furthermore, in the case of a split deflector, when removing snow from the intersection shown in Fig. 3, both deflectors 2A and 2B shown in Fig. 2 are closed when the point S1 is reached so that snow is not blown away. This is a really useful idea, as it is possible to avoid creating snow puddles in the shaded area S2 in Fig. 3 by passing through section S at this point, thereby preventing the occurrence of traffic disturbances.
