Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow-removal loaded vehicle used for snow removal on, for example, streets and highways.

[0002]

2. Description of the Related Art Conventionally, when snow is removed from a mountainous road by a rotary snow plow, snow collected on both sides of the road is thrown to the side of the road. However, since snow cannot be thrown in some snow-removing places or areas, the collected snow is loaded on trucks, transported to appropriate places, and discarded. At this time, loading on the truck is performed, for example, at an airport or the like, while the snowplow and the truck run side by side (two-person tripod state) during a time period when the airplane does not take off and land. However, if this type of loading is performed on general roads and highways,
This will cause traffic congestion.

Conventionally, as shown in, for example, FIG. 4, snow is loaded while the truck 36 is running in reverse so that the bed 37 of the truck 36 comes directly behind the snowplow 35. However, according to this method, the follow-up traveling in the reverse state of the truck 36 cannot be easily performed.

Accordingly, for example, Japanese Utility Model Publication No. 62-9371
As disclosed in Japanese Unexamined Patent Application Publication No. H11-264, there is provided a system in which a rear loading device is provided on an upper portion of a main body of a snowplow to load snow while following a truck in a forward state.

[0005]

However, according to the configuration equipped with the above-mentioned rear loading device, the snow removal capacity is increased so that the weight of the vehicle body on the snowplow side is increased, and thus the axle load on the highway does not exceed the regulation of 10t. Can be applied only to those not as large as about 250 ps class, that is, the snow removing ability is limited. In addition, it becomes a specially designed vehicle different from a normal snowplow having the same snow removal ability, and becomes extremely expensive.

Accordingly, the present invention according to claim 1 of the present invention provides a loaded vehicle for snow removal in which snow can be loaded while a truck is running in a forward state without increasing the weight of the vehicle body on the snowplow side. It is intended for that purpose.

[0007]

In order to achieve the above-mentioned object, the present invention provides a snow-removal loaded vehicle according to the first aspect of the present invention. A truck that can be connected and separated is provided, and a loading device is provided on the upper portion of the truck, and the loading device is characterized by comprising a duct portion and a conveyor portion disposed in the duct portion. is there.

Therefore, according to the first aspect of the present invention, by connecting the bogie to the rear part of the vehicle body of the snowplow via the traction device, the snowplow operation using the loaded vehicle can be performed. In this state, the truck is towed while the snowplow is running, and the truck is made to follow the truck in the forward state immediately behind the truck. As a result, the snow scraped by the snowplow can be thrown from the snow opening to the duct opening, and the snow that has entered the duct can be conveyed backward through the duct by the conveyor. Then, the snow can be discharged from the snow outlet onto the truck bed.

When the snowplow is driven without snow removal, the weight of the snowplow is reduced by supporting the load of the loading device on the bogie side. Even if the regulations are not exceeded, it can be applied to a large snowplow with a snow removal capacity of 400 ps class. And when the snowplow and the bogie are separated,
It will be a car with the same specifications as a normal snowplow with the same snow removal ability.
