CONSTITUTION:When right and left slide cylinders 13 are expanded or contracted a link 2 is oscillated about a hinge pin 3 and a slide rail 12 is put in a turning movement about a pin 5 and is angled while sliding and moving horizontally within a slide bracket 10. When an elevation cylinder 14 is expanded or contracted a blade 11 is put in a turning movement about a pin 9.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a rotary snowplow.

As shown in Figure 5, the most common road snow removal method in areas with heavy snowfall is to use a plow snowplow 19 to move the snow accumulated on the road to the roadside to create an electric field, which is then transferred to a rotary snowplow. This is a method of transporting and removing snow using 17.

However, during snow removal work using the rotary snowplow 17.

If the road surface is uneven, the lower part of the snow removal device 8 of the rotary snowplow 17 will float above the road surface.

Snow remaining on the road surface after snow removal work 2
Snow 22 spilled from snow removal device 1 or snow removal device 18 may be scattered. When the snow scattered on these roads freezes, it can interfere with the steering of general vehicles and cause traffic accidents. It was normal to perform the snow removal work again using a vehicle such as a plow snowplow or a grader 20.

However, snow removal by vehicles that follow rotary snowplows is simply snow removal for the purpose of leveling, and using a vehicle with large capacity for this purpose requires loss of manpower, cost, and time. big.

In view of the above-mentioned shortcomings of conventional road snow removal methods, the present invention provides a snow removal vehicle that is equipped with a means that enables the removal of remaining snow that could not be removed by rotary snow removal equipment to the roadside with a simple configuration. The challenge is to provide the following.

In order to solve the above problems, the snowplow vehicle according to the present invention has the following features:
The present invention is characterized in that a rotary snow removal device is attached to the front of the vehicle, and a snow removal blade device is provided to the rear of the vehicle.

Ichi-ri The snowplow of the present invention has the above configuration.

As shown in FIG. 6, it is conventional that the electric field brought to the roadside by the plow snowplow 19 can be thrown off the road or onto a truck by the rotary snow removal device 8 of the snowplow 17 according to the present invention. It will never change. However, the snow remaining on the road surface due to the floating of the lower part of the rotary snow removal device 18 from the road surface and the snow spilled from the rotary snow removal device 18 are removed to the roadside by the blades 11 of the blade device installed at the rear of the snow removal vehicle 17. It can be adjusted. Therefore, there is no need to use a vehicle such as a plow snowplow or grader separately from the rotary snowplow, and the blade device can be operated by the operator of the rotary snowplow, reducing labor costs and reducing the cost of the blade device. It is much less expensive than independent plows, snow plows, graders, and other vehicles.

The above blade equipment is designed to accommodate the work content.
It is desirable that the blade be provided with means for sliding the blade in the left and right directions with respect to the direction of vehicle travel, and means for adjusting the angle with respect to the direction of travel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

1 and 2 are rear views of an embodiment of the snowplow of the present invention, in which FIG. 1 shows the blade 11 in a position suitable for snow removal work, and FIG. 2 shows the state when forwarding. 3 and 4 show a side view and a plan view, respectively, of the snowplow.

As shown in these figures, a rotary snow removal device 18 is mounted in front of the snow removal vehicle 17. Rotary static eliminator! ! !
18 is no different from that equipped on a conventional rotary snowplow, so a description thereof will be omitted.

In the snowplow of this embodiment, a blade device is further mounted on the rear surface of the rear frame 15 of the rotary snowplow 17.

The blade device includes a frame l attached to the lower rear surface of the rear frame 15, and a link 2 that is rotatable in a horizontal plane around a hinge pin 3 provided at the left end of the frame t in the upper and lower figures of the frame t. , a cylinder 13 provided between the midpoint of the link 2 and the right end of claim 1, and a pin 6 extending horizontally on a bracket 4g provided integrally with the lower end of the pin 4 provided at the other end of the link 2. One end is pivotably supported in a horizontal plane and a vertical plane via a pin 7, and the middle part is attached to a bracket 5a integrally provided at the lower end of a pin 5 provided at the right end of the frame 1 via a pin 7. A slide rail 12 is slidably supported on the inside of an attached slide bracket 10, and a blade 11 is attached to brackets protruding from the lower surface near both ends of the slide rail 12 via pins 9 so that it can be flipped up. , and an elevating cylinder 14 provided between the vicinity of the tip of the blade and the slide rail 12.

The blade device is configured as described above.

By expanding and contracting the cylinder 13, the link 2
The slide rail 12 swings around the hinge pin 3 between the position shown by the chain line and the position shown by the solid line in the figure, and the slide rail 12 slides inside the slide bracket 10 and moves from side to side.
It rotates around the pin 5 and angles in the horizontal plane with respect to the vehicle running direction. Through these operations, the blade 11 attached to the slide rail 12 can also be adjusted for sliding and angle in the left and right direction.

Also, by expanding and contracting the elevating cylinder 4.

The blade 11 can be rotated around the pin 9.

Through the above series of operations, when the snowplow is being transported, the blade device is held in the leftmost position as shown in Figure 2, and the blade 11 is stored in the raised position so that it does not become an obstacle during transport. During one operation, as shown in FIG. 1, the blade is slid to a position suitable for the task and the blade is lowered to become ready for operation.

The pins 4 and 5, each having a bracket at its lower end, can slide and rotate in the vertical direction, and by interposing a compression spring 8 between the upper end of the bracket and the lower surface of the link 2, the blade 11 is elastic in the vertical direction. It is designed to move while touching the road surface. This allows the blade 11 to follow the unevenness and slope of the road surface.

Cylinders 13 and 14 are installed from inside the rotary snowplow driver's compartment.
A hydraulic pipe is installed so that remote control is possible and is operated by the driver of the snowplow.

During snow removal work, the slide rail 12 and blade 1 protrude outward from the side of the vehicle, so an indicator light 16 is installed at the protruding end of the slide rail 12 to prevent a rear-end collision from a following vehicle. It is provided.

In the above example, the structure is described for the case where the blade is extended to the right side of the vehicle for work, but depending on the nature of the snow removal work, snow removal work can be performed with the blade extended to the left side by manufacturing each part in the opposite direction. In addition, in order to hasten snow melting in early spring, it is also possible to scrape out accumulated snow on the roadside, and to install a lymph type basin crusher instead of a blade device.

Effects As described above, according to the present invention, it is no longer necessary to use a plow snowplow or grader to remove snow remaining on the road after snow removal using a rotary snowplow, and the plow or snowplow can be used for snow removal work on other roads. Compared to conventional snow removal methods, it is possible to significantly reduce the number of personnel, expenses, snow removal vehicles, etc., and improve work efficiency. In addition, the snow removal blade can be slid left and right and the angle can be adjusted, making it possible to handle snow removal operations in various situations.
