[Industrial applications]

 This proposal relates to a snow removal truck used for road snow removal work that combines three types of snow removal devices according to the work purpose and is highly efficient.

[0002]

[Prior art]

 Conventionally, in the case of a snow removal-only vehicle having this type of snow removal device, the side wings are installed in front of the grader even if three types of devices are installed as shown in Fig. 1 of Japanese Utility Model Laid-Open No. 3-93817. Therefore, in the case of simultaneous construction, it is not possible to treat the snow discharged by grader with side wings. In Japanese Utility Model Application Laid-Open No. 63-31119 and Japanese Patent Laid-Open No. 52-15146, only two types of devices are used, and a combination of three types is impossible. Also, in the case of a motor grader, a side wing device is provided as in JP-A-57-15708, but simultaneous work by two types of devices is limited, and high speed snow removal work is not suitable.

[0003]

[Problems to be solved by the device]

 In snow removal work on roads, snow removal work for widening roads and simultaneous snow removal work on roads and sidewalks cannot be performed with only two devices, snow plow and track grader. It is impossible to treat the snow discharged from the truck grader if it is installed in the area.

The present application has been made in view of such problems of the conventional technique, and an object of the present application is to provide the following things. In the present invention, three types of snow removing devices are installed on a snow removal truck, and a snow plow is installed on the front end of the snow removing vehicle to enable widening snow removal on the roadway and simultaneous snow removal on the roadway and sidewalks by performing three types of simultaneous work. A track grader 4 for road leveling was arranged in the lower center of the vehicle, and a McRae wing 5 for snow removal was arranged on the upper floor of the vehicle frame.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. That is, in the vehicle of the present application, a snow plow 3 for fresh snow removal is arranged at the front end of the vehicle 1, a track grader 4 is arranged at the lower center of the vehicle, and snow is removed at the upper floor 2 of the vehicle frame. This is a snow removal truck equipped with the McRae Wing 5. In this case, the snow removal McRae wing 5 is supported by the wing support 14 provided on the upper floor 2 of the vehicle frame via the lower elevating link 7 and the upper elevating link 7A facing the side of the vehicle 1 to remove snow. The hydraulic cylinder 12 for raising and lowering the McCrawling wing 5 is rotatably connected to the upper position of the wing support 14 by a support shaft 13, and the elongated hole 10 of the tip portion 9A of the hydraulic cylinder rod 9 and the raising and lowering link 7 are connected to each other. When the snow removal McCrawley wing 5 is lifted by a certain amount or more from the road surface during snow removal work, the snow removal McCrawley wing 5 is lifted and the pushing force is increased. If it becomes weak, it can be configured to descend due to the weight of the snow removal McCrawley wing 5. In addition, the snow plow 3 for fresh snow removal, the track grader 4 for road leveling, and the McLewing wing 5 for snow removal can perform either single snow removal work or two simultaneous work, In addition, it is possible to work simultaneously with three types of snow removal devices.

[0006]

[Action]

 The present invention operates as follows. Three types of snow removal devices of the present invention are installed on a snow removal truck, and a large amount of fresh snow is removed by a snow plow for fresh snow removal 3 for road snow removal work, and a road grader track grader 4 Repairs the road surface by removing irregularities on the road surface. The shavings discharged at this time will be deposited on the shoulders of snow on roads without sidewalks, or on the sidewalks in the case of simultaneous snow removal work on roads and sidewalks. In the early stage of the snowfall season, it is easy to remove this snow off the road with the well-known snow removal side wings. However, as the amount of snowfall increases, the amount of snow on the outside of the road also increases, and the snow wall, that is, the snow bank, is formed by the accumulation of the discharged snow on the roads and sidewalks. This snow bank impedes the flow of snow that has been removed by a known snow removal side wing. Therefore, the snow bank is scraped out onto the road by the snow removal McRae Wing 5 of the present invention. In other words, the inside snow removal work is performed. The snow thrown inside is thrown to the outside of the road by a succeeding rotary snowplow.

In the above snow removal method, the McRae wing 5 for snow removal is indispensable, and in the present invention, the snow plow 3 for fresh snow removal and the track grader 4 for road leveling remove the snow on the snow bank together with the discharged snow. It is a method of throwing this snow out by using a rotary snowplow to put it inside out. During the above snow removal work, the long hole 10 provided at the tip portion 9A of the hydraulic cylinder rod 9 of the lifting hydraulic cylinder 12 for lifting the above-mentioned snow removal McCrea wing 5, the connecting pin 8 and the connecting portion of the lifting link 7 Due to the loose fitting, the effect of undulating the McCrawley wing 5 for snow removal on the road surface is large.
