Description

[Detailed description of the invention] [Industrial application field] This invention is a new snow plow that can smoothly remove snow from median strips with rows of protruding objects such as cat eyes without causing any obstacles. It is related to.

[Conventional technology and issues to be solved]

Currently, in narrow areas such as mountainous areas, there is no space to set up driving lanes and passing lanes, so two-way traffic is unavoidably adopted, and cat eyes are installed to distinguish between upper and lower lines. I'm making do with it.
However, since a portion of this cat's eye protrudes from the road surface, there is a risk that the cat's eye will collide with and be damaged during snow removal in the winter.
It greatly interferes with work.

Therefore, in order to remove snow from the median strip where the cat eyes are installed, the lower edge of the plow must be lifted above the road surface to avoid collision between the plow and the cat eyes. At present, the only option is to leave the median strip where the Cat's Eye stands and clear the snow. If the snow removal is carried out by lifting the plow wedge, a layer of snow will remain on the median strip and the driving lanes by the height of the lift, and in order to remove such a layer of snow, another final snow removal will be required. Therefore, snow removal work is 2
This process is truly inefficient. In this case, snow naturally remains in the shape of ribs on the median strip.

On the other hand, if the snow is removed while leaving the cat's eye area, the remaining snow on the median strip will gradually increase in height as the snow is removed, and the snow near the road surface will melt due to geothermal heat and form a mushroom shape (〓). However, as the snow grows and becomes heavy, the umbrella at the top collapses and falls onto the road, causing problems such as narrowing the width of the travel lanes that have been cleared of snow.

In this way, no matter which method is used, re-removal of snow from the median strip is essential on roads in snowy countries, and unless this is thoroughly enforced, the lanes will become narrower, leading to various troubles and accidents. The solution of problems such as how to rationalize median strips can be said to be an urgent task for road management.

This invention not only solves the above-mentioned problems, but also goes one step further by creating a snow plow that can efficiently remove snow from driving lanes and median strips in a single operation without damaging the snow plow. The technical challenge is to provide such information.

[Means adopted to solve the problem]

The means adopted by the present inventor in order to solve the above technical problem will be explained as follows based on the accompanying drawings.

That is, the present invention is: A one-way snow plow that is disposed at the front of the snowplow 1 in a unidirectional flow from the median strip side to the roadside, and removes snow by pushing snow on the road to one side. A non-flat line snow removal device M having an elastic snow sweeping member 4 having an inclination opposite to the edge inclination of the plow body 2 is installed at the side end 21 on the side of the median strip of the plow body 2, approximately along the cutting edge extension line l of the plow body 2. It is characterized by extending in parallel.

〔Example〕

Non-flat line snow processing device M that forms the main part of this invention
must satisfy the following conditions.

(a) It can be attached to a snow plow as an accessory, has a simple structure, and can be provided at low cost.

(b) It should be possible to accurately see the condition of the snow removal road surface from the driver's seat, and the work should be easy.

To be able to smoothly remove snow from the median strip on a non-flat surface without damaging the cat eye.

The embodiment device shown in FIG. 1 and FIG.
A one-way snow plow installed in the front part of the vehicle in a unidirectional flow from the median strip side to the roadside, which removes snow by pushing snow on the road to one side, and is equipped with a non-flat line snow removal device M. It shows.

A non-flat line snow processing device M is arranged above the cat eye 3, and this device M
The snow removed by this is pushed forward of the plow body 2. In the illustrated embodiment, an elastic snow repellent member 4 made of spring steel wire bundled into a brush shape is attached to the processing device M, and the elastic snow repellent member 4 is placed in front of the cutting edge extension line l of the plow body 2 and is positioned further forward than the side end 21 of the plow body 2. The cutting edge 6 of the plow body 2 is arranged so as to be located outward, and its cutting angle is
It has a more pure square shape and is designed to sweep snow toward the plow body 2. In the drawing, reference numeral 5 indicates a rubber plate attached to the surface of the elastic snow repellent member 4 in the direction of movement, and is provided for cushioning against the cat eye 3. In addition, the same rubber plate 5
This also prevents the problem that only the brush-like snow repellent member 4 can cause snow to fall off from the gaps between the wire rods.

Figure 3 shows the cutting edge 6 of the plow body 2.
This figure shows the arrangement relationship between the non-flat line snow processing device M and its configuration, and the arrow → indicates the direction of movement thereof. In addition, the code α in the figure indicates the plow body 2.
is the cutting angle of cutting edge 6 at , and β
is the arrangement angle of the brush and rubber plate 5 of the snow repellent member 4 of the processing device M, and the reference numeral 3 is the cat eye arranged in a row in the median strip section.

Thus, the embodiment device obediently follows the shape of the road surface due to the elasticity of the elastic snow repellent member 4 and the rubber plate 5, and the upper surface of the cat eye and the cat eye 3, 3...
This allows you to cleanly remove snow from the recesses between the two.

Reference numeral 7 indicates an auxiliary plow, and the snow repellent member 4,
In addition to backing up the function of the rubber plate 5, even if the snow repellent member 4 and the rubber plate 5 are unable to withstand the resistance during snow removal and leave snow behind, it is possible to remove snow to the minimum required level. Remove.

Next, if there is no oncoming traffic lane and the operation of the non-flat line snow processing device M is not required, a mechanism for folding and storing it within the width of the plow body 2 is required. Fourth
FIG. 5 shows a folding link mechanism for storage.

FIG. 4 is a plan view, and FIG. 5 is a view taken from the rear of the plow body 2.

The folding link mechanism in this embodiment basically consists of a hydraulic cylinder 10, a lever 13, a bell crank 14, and a bracket 1 provided on a snow repellent member M.
6. It is composed of a hinge piece 17 pivotally attached to the bracket 16, and a rod 18 that connects the hinge piece 17 and the bell crank 14. A fluid cylinder 10 is attached using a pivot 9 of a bracket 8 provided on the back as a fulcrum.
A lever 13 swings about the pivot 12 of another bracket 11 as a fulcrum, and a bell crank 14 supported coaxially with this lever 13 is pivoted by a pin 15, and the other end is non-flat. Bracket 1 installed on the back of the line snow processing device M
The processing device M is folded into the plow body 2 by the associated movement of a rod 18 which is pivotally connected to the plow body 6 by a hinge piece 17.

In FIG. 4, A, B, and C are the rod 18 and lever 14 depending on the extended state of the fluid cylinder 10.
It shows the positional relationship of the connecting pin 15 with the
Along with this, the position of the connecting pin 17 between the rod 18 and the processing device M changes from X to Y to Z. That is, since the processing device M is pivotally connected to the plow body 2 by the pin 19, it can be rotated clockwise or counterclockwise using this as a fulcrum.

When the fluid cylinder 10 is extended and the connecting pin 15 between the rod 18 and the bell crank 14 is at position B, the other hinge piece 17 of the rod 18 is at position Y, and at this point the processing device M A stopper 20 provided on the plow is regulated by coming into contact with the side plate 21 of the plow body 2,
The counterclockwise rotation of the processing device M is stopped. When the fluid cylinder 10 is further extended and the connecting pin 15 between the lever 14 and the rod 18 is at the position C, the hinge piece 17 between the rod 18 and the processing device M is at the position Z.
The processing device M, which is at this position and whose rotation is suppressed by the stopper 20, swings upward using the pin 22 as a fulcrum and rises to avoid the cat's eye 3.

When the non-flat line snow processing device M is required, the connecting pin 15 between the rod 18 and the lever 14 is moved from C→B→ by reducing the size of the fluid cylinder 10.
A, the hinge piece 17 between the processing device M and the rod 18 becomes Z→Y→X, and is ready for operation immediately.

[Operations and effects of the present invention]

In the present invention, since the non-flat line snow removal device M having the above-mentioned configuration is attached to the snow plow, the snow removal from the non-flat median strip portion where the cat eyes are arranged is carried out by the plow body 2. Since it can be done smoothly in conjunction with the snow function, it is now possible to remove snow from driving lanes and median strips in one run, which was previously considered impossible, and can greatly contribute to improving the efficiency of road snow removal.
