Description

  The present invention relates to an improvement of a snow plow road-side snow discharge adjusting mechanism in a snow removal vehicle, and more specifically, a snow removal vehicle capable of performing an efficient snow removal operation without complaints, without obstructing a driver's field of view, and having few failures. This invention relates to a roadside snow discharge control mechanism of snow plows in Japan.

  As is well known, when snow accumulated on the road in the winter becomes an obstacle to traffic, it is common to perform snow removal work on the road using a snow removal vehicle such as a snow removal grader or a snow removal dozer.

  In the snow removal work using the snow removal vehicle, the snow on the road is scooped up by the snow plow of the snow removal vehicle and accumulated forward, and the accumulated snow flows to one side by the inclination (propulsion angle) of the snow plow and beside the road. Although it was discharged, it blocked the pedestrian crossing at the intersection and created a hard snow bank at the entrance of the house to prevent traffic, causing problems for residents.

  At intersections and the like, it is very dangerous for traffic if snow removal from the snow plow remains, so extra repair work to remove the snow removal is inevitable.

  Therefore, in the past, the present applicant has arranged a shutter plate on the side of the snow plow as in <Patent Document 1>, and moved the shutter plate up and down by a parallel link of a frame attached to the vehicle body, We have proposed a road surface leveling device equipped with a shutter device that can stop snow removal from a snow plow.

  However, with regard to the above-described prior art, in a snowplow vehicle in which a snow plow is disposed in front of the driver's seat, the shutter plate with the retracted shutter plate raised upward is partly viewed by the driver. Occasionally it was dangerous.

  On the other hand, conventionally, a housing for storing a shutter plate and a fluid cylinder as a drive unit is connected to a side portion of the snow plow, and the shutter plate is taken in and out of the housing to remove snow. A snow plow shutter device for adjustment is also known (see, for example, Patent Document 2).

However, in the above conventional shutter device, since the housing is arranged side by side on the side of the snow plow even after the shutter plate is stored when not in use, there is a possibility that it may be damaged by contact with the curb of the sidewalk. there were.

Further, with respect to the retracted shutter plate 2, the shutter plate 2 is brought into sliding contact with the upper force end side 21 of the shutter plate 2 as the hinge arm 3 rotates downward with the second hinge portion H ₂ as a fulcrum. Since the lift guide member 8 that can be lifted upward is arranged on the snow plow, the shutter plate 2 can be opened to the outside of the plow without contacting the snow plow 1.

In this embodiment, the shutter plate 2 is in the middle of the downward movement by tilting the rotation axis of the first hinge portion H ₁ formed by the upper force end side 21 of the shutter plate 2 and the hinge arm 3 to the road side. It automatically opens to the outside of the plow using its own weight.

  Further, in this embodiment, a pad member 22 made of a hard and wear-resistant metal material is attached to a contact portion between the pressing guide member 7 and the lift guide member 8 on the upper force end side 21 of the shutter plate 2. Reinforcement is performed.

  Further, on the snow plow 1, a support base 9 capable of supporting the shutter plate 2 in the sideways state from below is provided to reduce the load on the hinge portion.

  On the other hand, a movable plate portion 24 is attached to the shutter plate 2 body by being slidably connected to the guide hole 23 with a pin 24a, and the movable plate portion 24 is configured to be rotatable with respect to the shutter plate 2, It is configured to overlap with the shutter plate 1 by its own weight when it is up, and to be drawn downward by its own weight and return to its original state when it is down.

  In the present embodiment, the bracket B including the support joint 4, the fluid cylinder 5, the link member 6, the pressing guide member 7, the lift guide member 8, and the support base 9 is mounted on the snow plow 1. The bracket B can be detached and repaired or replaced easily.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of the “Claims”. 1 may not be in the form of a single flow that flows only on one road side, but may be a V-shaped one that flows from both sides to the road side. In that case, shutter plates 2 are disposed on both sides of the snow plow 1.

  Further, the push / pull lever 3 and the fluid cylinder 5 may be directly linked without using the link member 6, and both belong to the technical scope of the present invention.

  In recent years, snow removal work on roads in snowy areas has become indispensable for residents in that area to live without hindrance, and in order to remove snow on many roads with limited snow removal vehicles, Work efficiency is required. In addition, there are many areas where depopulation and aging have progressed recently, and in such areas, elderly people have to perform manual snow removal in front of the entrance, which is hard work more than imagined.

  Under such circumstances, the roadside snow removal adjustment mechanism of the snow plow in the snow removal vehicle of the present invention can eliminate the snow removal problem in front of the entrance by improving the efficiency of snow removal work, and is also excellent in terms of use and safety.
