Description

  The present invention relates to a snow removal device that is used with a snow removal vehicle and removes snow from a road having a simple median.

In a two-way road, a simple separation zone or a central line (collectively referred to as a simple central separation zone) is provided at the center as a boundary separating the upper and lower lines.
The simple median strip is generally narrow, and there are many attachments such as curbs with rubber poles and cat's eyes attached. In the snow removal work of the simple median with such attachments, if the simple median strip is scraped directly with the plow of a snow removal vehicle, the attachments will be damaged, and snow removal is performed avoiding this. . For this reason, the snow in the simple median remaining without being removed grows higher each time it snows, and finally the upper part collapses onto the road. The fallen snow is scattered in the form of crushed blocks on the roadway, which may make it dangerous for vehicles to pass.

  Patent document 1 “Snow plow having a function of removing snow from the median strip” copes with such a situation, and “the edge inclination of the plow body 2 on the side end 21 on the median strip side of the plow body 2 is described. A non-flat line snow treatment device M having a reverse-sloped elastic snow sweeping member 4 is extended so as to be substantially parallel to the cutting edge extension line 1 of the plow body 2 ”.

In this structure, the non-flat line snow treatment device M includes an elastic snow sweeping member 4 composed of a rubber plate 5 and a brush in which spring steel wires are bound in a brush shape, and protrudes from the upper surface of the central separation band using these elasticity. This removes the snow that has fallen on the upper surface of the cat's eye and the recess between the cat's eyes while following the unevenness of the cat's eye. It is presumed that it can go smoothly without causing any obstacles.
That is, the snow on the upper surface of the median strip is removed by the non-flat line snow treatment device M attached to the side end of the plow body 2.

As a result, it is possible to remove snow on the median strip left by the plow body 2. However, since the elastic snow sweeping member 4 moves so as to follow the upper surface of the cat's eye, if a rubber pole or the like is erected on the central separation band, it cannot be used due to an obstacle.
In the structure of Patent Document 1, the snow removed from the central separation zone is pushed forward in the traveling direction of the plow body 2 and is transported to the road side along with the accumulated snow scraped from the road surface.

Further, the non-flat line snow treatment device M can be moved to an upper retreat position by a folding link mechanism having a fluid pressure cylinder 10.
As in this device, a snow removal device having a mechanism for attaching a snow removal auxiliary device to the side of the plow body and moving it to a working position and a retracted position by a folding link mechanism such as a hydraulic cylinder, for example, There are many things like Patent Document 2.

Japanese Utility Model Publication No. 2-26961 Japanese Utility Model Publication No. 61-76818

The non-flat line snow treatment device M of Patent Document 1 is a device provided with a brush and a rubber plate 5, but is a full-fledged device (attachment) provided with a fluid pressure folding link mechanism, and has a considerable weight. Presumed to be.
For this reason, once attached to the side end of the plow, the apparatus is retracted upward without considering attachment / detachment. Accordingly, even when the snow removal vehicle using this device does not use this device, the heavy non-flat line snow treatment device M is moved while attached to the right side of the plow body 2, and it is difficult to keep the plow body 2 horizontal. Or use the fuel of the snow removal vehicle in vain.

  Accordingly, an object of the present invention is to provide a snow removal device that is lightweight and can be easily attached / detached, can remove snow from a simple median strip even when a rubber pole is present, and is inexpensive.

A snow removal device with a brush device attached to the plow.
The brush device has a brush, and the brush has a structure in which a large number of linear materials made of synthetic resin are bundled with flexibility and elasticity at one end, and the other end does not hang down. The brush linear material is made of polypropylene or vinyl chloride and has a diameter of about 3 to 5 mm and a length of about 400 to 600 mm.
While this straight material is hard as a material, it has elasticity and is highly bent and recoverable. For this reason, when the edge part of a brush is fixed and it keeps horizontal, it has the rigidity of the grade which the other end of a brush hardly falls.

The brush device is disposed on the rear surface side of the right end of the plow in the traveling direction.
Then, when the brush device is attached to the plow, the tip of the brush is protruded horizontally to the right rather than the right end of the plow as viewed from the front in the traveling direction. The dimension to project is a dimension at least where the tip of the brush reaches the center of the simple median strip. That is, the brush reaches an area of the rubber pole standing on the simple median strip.

In a brush device, a plurality of brushes may be attached in parallel in the direction of travel of the plow.
The straight material of the brush is short in the forward direction in the direction of the plow in plan view, long in the rear side, and when the brush is attached to the bracket of the plow, the tip edge of the brush is relative to the direction of the plow It may be arranged to intersect at an acute angle that narrows from the front to the rear.
The brush device includes a bracket, and the brush may fix one end of a plurality of linear members around the core material, and may fix the core material to the bracket.
In addition, the base of the brush may be fixed to the bracket by a U-bolt from the outside of the linear member in a range where the core member exists.

The snow removal device of the present invention has a very simple structure and is lightweight because it can remove snow from the simple median zone simply by attaching a brush device to the plow (including attachment by welding). In addition, by using a detachable means such as a bolt for fixing the brush device, the brush device can be easily detached from the plow as required.
Moreover, since it is usually only preparing a brush apparatus, it can prepare cheaply.

Since the snow in the simple median strip is swept away by the brush of the brush device every time the snow is removed by the plow, it does not grow high. For this reason, it is possible to prevent a situation in which snow that has grown high in the simple median zone collapses and hinders vehicle travel.
In addition, since the accumulated snow cover is often fresh snow, it spreads widely and finely on the road, so there is no significant influence on the running of the vehicle.
Since the brush only rubs against attachments such as rubber poles, they will not be damaged. Then, near the base of the rubber pole and snow between the rubber poles are removed by the brush.

[Example 1]
1 (a) and 1 (b) are for explaining the background in which the present invention is required, and show the snow cover 2 remaining in the simple median 1 after the snow removal work by the conventional snow removal device. Indicates the state. Rubber poles 3 as attachments are erected at a predetermined interval on the simple central separator 1. If there is further snowfall in this situation, it falls on the snowfall 2 and is not removed even if the snow is removed from the traveling road, so that the height of the snowfall 2 increases every time it snows, and finally the upper part collapses on the road.

The snow removal device 4 (FIG. 2) according to the present invention includes a plow 6 mounted in front of the snow removal vehicle 5 and a brush device 7 attached to one end of the plow 6.
In this embodiment, the brush device 7 (FIG. 3) includes a bracket 9 and a brush 9 that widens in a broom shape. In this embodiment, the brush 9 is formed by bundling a number of polypropylene resin linear members 10 around a core member 11.
In this embodiment, the straight member 10 has a diameter of 3 mm and a length of 450 mm. The straight member 10 is hard as a material, but has elasticity and has a property of being bent and recoverable. For this reason, when the end portion is fixed and the brush 9 is kept horizontal, the brush 9 has such rigidity that the other end of the brush 9 does not hang down.
In addition, the raw material of the linear material 10 is not limited to polypropylene, and may be another synthetic resin or spring steel linear material. In any case, the linear member 10 only needs to be provided with rigidity to the extent that the other end hangs down with respect to one end when gathered as the brush 9.

The core material 11 is a metal round bar, and in this embodiment, has a diameter of 25 mm and a length of 90 mm.
A large number of the linear members 10 are arranged around the core member 11, and the base 12 is bound and fixed to the core member 11 by using an adhesive in combination. The fixing portion is the base 12 (one end) of the brush 9, and the brush 9 has a broom shape that spreads from the base 12 toward the tip (the other end).
In this embodiment, the tip of the straight member 10 in the brush 9 is shortened toward the front in the traveling direction, and the tip line (a) of the straight member 10 is sharp and the traveling direction is narrowed from the front to the rear in the traveling direction. (Fig. 3).
The bracket 8 is for attaching the brush 9 to the stay 15 on the plow 6 side. The brush 9 is fixed to the bracket 8 by a through bolt 13 that penetrates the end of the core member 11 in the diameter direction of the core member 11. The brush 9 is also fixed by fitting U bolts 14 along the outer surface of the linear material 10 bundled in the area where the core material 11 exists, and screwing the bolt portions at both ends of the U bolt 14 to the bracket 8. ing.

Since the brush 9 is fixed to the bracket 8 at the two locations of the through bolt 13 and the U bolt 14 as described above, the brush 9 is fixed in a stable state. As a result, the attachment of the brush 9 is not loosened during the operation, and the rightward protruding angle does not change or fall off. In addition, the length of the both-ends bolt part of the U volt | bolt 14 is provided with allowance, and a U-shaped part can be drawn near to the bracket 8 side in the case of screwing.
Reference numeral 16 is a displacement suppression member, which is in the form of a saddle cover made of synthetic resin, and is fixed to the base 12 of the brush 9. The displacement suppression member 16 covers the rear half of the brush 9 on the base side, and supports the base of the brush from the rear side in the traveling direction of the plow 6.

The brush device 7 is disposed on the rear surface side of the right end in the traveling direction of the plow 6 (FIG. 4).
When the brush device 7 is attached to the plow 6, the front end of the brush 9 protrudes horizontally from the right end of the plow 6 when viewed from the front in the traveling direction (FIG. 2). In addition, it becomes the left in FIG.
The extent to which it protrudes is a dimension in which at least the tip of the brush 9 reaches the center of the simplified central separation band 1. In other words, the brush 9 is disposed so as to reach the portion of the rubber pole 3 erected on the simplified central separation band 1.

The snow removal vehicle 5 to which the snow removal device 4 is attached travels with the right end of the plow 6 along the right end of the simple median strip 1 and the tip of the brush 9 reaching the center of the simple median strip 1 when working. .
In the snow removal work, the plow 6 scrapes off the snow on the traveling road, moves the scraped snow to the left along the curved surface of the plow 6, and discharges it to the road side opposite to the simple median strip 1.
At the same time, the snow accumulated on the simple median strip 1 on the rear side of the right end of the plow 6 is discharged (swept out) by the tip of the brush 9 and diffused widely in the traveling path. The payout is performed by repeating the bending and the bullet of the brush.

At this time, when the brush 9 tries to bend unnecessarily large due to resistance from snow accumulation or resistance when rubbing the rubber pole 3, excessive displacement is suppressed by the displacement suppression member 16. As a result, it is possible to reinforce the effect of removing snow by the brush 9 and to prevent the brush 9 from being deteriorated at an early stage due to repeated excessive bending.
In this embodiment, the payout by the brush device 7 is continuously performed by two brushes 9 arranged at the front and back in the traveling direction while maintaining a relatively wide range occupied by the two brushes. High ability to pay off snow on belt 1

In addition, the replacement and attachment of the brush device 7 is light because the brush device 7 itself is a device mainly composed of the bracket 8 and the brush 9, and in addition, the bolts fixing the bracket 8 to the stay 15 are removed. Because it can be done just by wearing it, it can be done easily.
The linear material 10 of the brush 9 is such that the linear material 10 constituting the brush 9 does not collide with the rubber pole 3 at a stroke due to the inclination of the tip line (a), and the brush is smooth with respect to the rubber pole 3. Scratch.
In this embodiment, the brush 9 is attached to the stay 15 by the bracket 8. However, the brush 9 can be directly attached to the stay 15 by the through bolt 13 and the U bolt 14 penetrating the core material 11.
In this case as well, the attachment and removal of the brush 9 can be performed simply by attaching and detaching the through bolt 13 and the U bolt 14.
