Description

[Detailed Description of the Invention] The present invention relates to a snowplow equipped with a snow removal device for removing snow accumulated on a road surface.

Generally, the snow removal device has a blade, which is connected to a support bracket via a drive mechanism, and is driven up and down by the drive mechanism. The support bracket is attached to a side surface of the chassis frame of the snowplow between the front wheels and the rear wheels.

However, when the support bracket is attached to the chassis frame, it must be ensured that the support bracket does not interfere with parts that protrude from the side of the chassis frame, such as the spring hanger bracket, fuel tank, battery box, etc. In order to prevent the support bracket from interfering with various parts, the dimension between the front and rear wheels of the chassis frame, that is, the wheelbase, must be made large, which has the disadvantage of making the chassis frame longer.

This idea was developed based on the above circumstances.
The purpose of this is to provide a snow removal system that allows the support bracket of the drive device to be mounted so as not to interfere with various parts provided on the side of the chassis frame, thereby eliminating the need to lengthen the chassis frame. It's about providing cars.

An embodiment of the present invention will be described below with reference to the drawings. 1 in the figure is the chassis frame of the snowplow.
A pair of spring hanger brackets 2 are provided at both longitudinal ends of both sides of the chassis frame 1, respectively. A leaf spring 3 is attached to each pair of spring hanger brackets 2,
A front wheel 4 and a rear wheel 5 are supported by these leaf springs 3 via an axle (not shown).

A cab 6 is provided on the upper surface of the front wheel 4 side of the chassis frame 1, and a subframe 7 is attached to the remaining upper surface. A snow removal device 8 is supported on a side surface of the subframe 7 at a portion located between the front wheels 4 and the rear wheels 5. This snow removal device 8 includes a support bracket 9 fixed to the side surface of the subframe 7. A drive cylinder 10 is swingably supported on this support bracket 9 via a connecting piece 10a. The rod 11 of this drive cylinder 10 is pivotally connected to a first connecting portion 13 provided on a mounting shaft 12. A pair of second connecting portions 14 are provided on the mounting shaft 12, and one end of a parallel link 15 is pivotally connected to each of the second connecting portions 14. The other ends of the pair of parallel links 15 are pivotally connected to support brackets 9 on the side surfaces of the subframe 7. Further, a blade 16 is attached to the lower end of the mounting shaft 12 facing toward the front wheel 4, and a third connecting portion 18 is provided protruding from the rear side of the intermediate portion of the mounting shaft 12. The third connecting portion 18 engages with one end of a drive cylinder 19, and a blade 19 is pivotally attached to the other end of the drive cylinder 19. Therefore, the drive cylinder 1
When the rod 11 is activated and the rod 11 is protruded, the blade 16 is lowered, and when the rod 11 is retracted, the blade 16 is raised.

Furthermore, a fuel tank 22, a battery box (not shown), and the like are provided on the side surface of the chassis frame 1. Further, a balance weight 23 indicated by a chain line is loaded on a portion of the upper surface of the subframe 7 on the rear wheel 5 side.

According to the snow removal vehicle having such a configuration, a subframe 7 is provided on the upper surface of the chassis frame 1, and a support bracket 9 for the snow removal device 8 is attached to the side surface of the subframe 7. Therefore, the support bracket 9 can be attached to the side surface of the subframe 7 without being restricted by the spring hanger bracket 2, fuel tank 22, etc. provided on the side surface of the chassis frame 1. In other words, since it is not necessary to secure the space necessary for attaching the support bracket 9 to the side surface of the chassis frame 1, the chassis frame 1 can be shortened by that much.

Further, since the subframe 7 and the snow removal device 8 can be made into a unit in advance and attached to the chassis frame 1, the work of attaching the snow removal device 8 to the chassis frame 1 can be facilitated.

As described above, in the present invention, a subframe is provided on the upper surface of the chassis frame of a snowplow, and the support bracket of the snowplow device is attached to this subframe. Therefore, the support bracket can be attached to parts such as the spring hanger bracket and fuel tank that protrude from the side surface of the chassis frame without being restricted. That is, since there is no need to secure a space for attaching the support bracket to the side surface of the chassis frame, the snow removal device can be provided without increasing the length of the chassis frame.
