Description

[Detailed Description of the Invention] [Industrial Application Field] Snow processed by plows, rotary snowplows, etc. accumulates on both sides of roads in areas with heavy snowfall, forming snow embankments, and snowstorms, etc. occur on the snow embankments. A snow eave is formed. As a result, road width will decrease. Furthermore, these snow embankments and snow canopies are extremely dangerous to vehicles and people because they cannot withstand their own weight due to subsequent snowfall or temperature changes and suddenly fall onto the road. Therefore, prompt disposal of snow embankments and snow eaves is strongly required. The rotary snowplow according to the present invention is used for such snow embankment and snow eaves treatment.

[Prior Art] Conventionally, a rotary snowplow 14 as shown in FIG.
As a result, 13 snow embankments and snow eaves were being cut and the final road width was secured.

[Problem to be solved by the invention] However, the height of the snow cutter 1 is limited by the Vehicle Restriction Ordinance.
Because the snow must be kept at 3.8 meters or less, we had to rely on other specialized vehicles or dangerous human labor to clear the higher snow embankments and snow eaves, as shown in Figure 11.

An object of the present invention is to provide a snowplow that can quickly and safely handle not only low snow banks and snow eaves and ensuring road width, but also snow banks and snow eaves of 3.8 meters or more.

B. Structure of the invention [Means for solving the problems] A rotary snowplow includes a vehicle body and a processing device.

The vehicle body is equipped with a rotary snow removal section at the front, and the vehicle body has a mounting base, a cutting blade, and a cylinder.

The processing device is fixed to the rear of the vehicle body, and the cutting blade is pivotally connected to a mounting base and is swingable on a plane perpendicular to the traveling direction of the rotary snowplow. The cylinder is suspended between the mounting base and the cutting blade, which makes it possible to adjust the upright angle of the cutting blade.

A more desirable configuration is as follows.

That is, the mount includes a guide, a pedestal, and a cylinder.

The guide is fixed to the rear of the vehicle body.
The pedestal is guided by a guide in a horizontal direction and perpendicular to the direction of movement of the rotary snowplow, and the cutting blade is pivotally connected to the pedestal. The cylinder of the processing device is suspended between a pedestal and a cutting blade. The cylinder of the mount is suspended by a guide and a pedestal, thereby making it possible to adjust the amount of movement of the pedestal to the outside of the vehicle body.

[Operation] The cutting blade is raised from the folded state by a cylinder, and the angle of the cutting blade is adjusted depending on the condition of the snow embankment and snow eave. When the mounting base consists of a guide, a pedestal, and a cylinder, the amount of movement of the pedestal to the outside of the vehicle is adjusted by a hydraulic cylinder.

Next, the rotary snowplow is moved, and the snow banks and snow eaves are cut by the rotary snowplow section.

Snow embankments and snow eaves that exceed the height of the snow cutter are cut off with a cutting blade and dropped to the rear of the vehicle. By moving the snowplow backwards and moving it forward again, the rotary snowplow removes the fallen snow off the road.

[Example] In the following, the same numbers indicate the same or corresponding parts.

In FIGS. 1 to 4, a rotary snowplow 14 has a vehicle body 15 and a processing device 16.

The vehicle body 15 is equipped with a rotary snow removal section 20 at the front. The processing device 16 has a mounting base 4, a cutting blade 2, and a cylinder 5. The mounting base 4 has a guide 17,
It has a pedestal 3 and a cylinder 6.

The guide 17 is fixed to the rear of the vehicle body 15. The pedestal 3 is guided by a guide 17 in the horizontal direction and in the vertical direction (left-right direction in FIG. 2) with respect to the traveling direction of the rotary snowplow 14 (left direction in FIG. 1). The cutting blade 2 is pivotally attached to the pedestal 3 so as to be swingable on a plane perpendicular to the direction of movement of the rotary snowplow 14. The cylinder 5 is suspended between the pedestal 3 and the cutting blade 2, so that the upright angle of the cutting blade 2 can be adjusted. The cylinder 6 has a guide 17 and a frame 3
The amount of movement of the frame 3 to the outside of the vehicle body 15 can be adjusted.

Note that 7 is a sliding bearing. 9 is a turnbuckle, and 8 is a bracket for the turnbuckle.

The rotary snow removal section 20 includes a snow cutter 1 and an auger 1.
0, a blower 11, and a chute 12. In FIGS. 8 and 9, the snow cutter 1 is pivotally attached to the vehicle body 15 so as to be swingable. Folding mechanism 21
consists of a cylinder 22 and a lever connecting the cylinder 22 and the snow cutter 1, and can adjust the standing angle of the snow cutter 1.

The operation of this embodiment is as follows.

First, the cutting blade 2 is raised from the folded state (two-dot chain line in Figure 2) using the hydraulic cylinder 5, and the angle K of the cutting blade 2 is adjusted depending on the condition of the snow embankment and snow eave, and the hydraulic cylinder 6 is used to adjust the angle K of the cutting blade 2 to the outside of the vehicle on the frame 3. Adjust the amount of movement L to complete the working posture. When the snow cutter 1 of the rotary snow removal section 20 has a folding mechanism, the standing angle of the snow cutter 1 is similarly adjusted.

Next, the rotary snow blower 14 is moved to cause the snow cutter 1 to enter the snow embankment/snow eave. The snow banks and snow eaves cut by the snow cutter 1 fall in front of the auger 10 and are processed by the auger 10.

In the above process, if there is a snow embankment or snow eave part that exceeds the height of the snow cutter 1, it cannot be processed. This portion is cut by the cutting blade 2 and falls toward the rear of the vehicle. After the vehicle is moved backward once, it is moved forward again, and the fallen snow is thrown off the road by a rotary snow removal section 20.

5 to 7 show another embodiment, in which the mount 4 consists of only one frame 31. The cutting blade 2 is pivotally attached to the frame 31 and is swingable on a plane perpendicular to the direction in which the rotary snowplow 14 moves. The cylinder 5 is suspended between the cutting blade 2 and the frame 31, so that the upright angle of the cutting blade 2 can be adjusted.

The operation is the same as in the previous embodiment except that the movement amount L of the pedestal 3 is not adjusted.

C. Effects of the Invention According to the present invention, the work can be completed with a single rotary snowplow, and there is no need for a dedicated vehicle other than a rotary snowplow or the use of dangerous human power. Therefore, various effects can be achieved, such as improved processing capacity, reduced traffic stoppage time during snow embankment/snow eave processing work, and smoother traffic flow in winter.
