Description

[Detailed description of the invention] [Industrial field of application] This invention provides a snow resistance plate installed at the rear of the grading rotor that can be adjusted up and down according to the snow quality, and moves it up and down according to the snow quality. This invention relates to a snow crushing structure of a ski slope leveling device that can freely adjust the degree of crushing and level the slope cleanly using a finished leveling plate.

[Conventional technology]

In the slope leveling device, a driving leveling rotor is provided between the left and right walls of a rotor support frame, and a finishing leveling plate is provided behind the driving leveling rotor.

The ski slope surface is leveled by crushing it with this drive leveling rotor, and then the final leveling is done by compacting the snow with a finishing leveling plate. Although it is easy to crush fresh snow, it is difficult to crush wet snow or hard snow. If this is not done properly, the result will be sending clumped snow backwards.

For this reason, it becomes impossible to level the ground with the finished leveling board,
Since the finishing leveling board only climbs over the lumps of snow and does not level the ground, this lump of snow is left on the slope surface, resulting in an uneven and wavy slope surface, which has the disadvantage that the ground is not leveled at all.

[The problem that the idea aims to solve]

The present invention solves this problem by installing a snow resistance plate behind the drive grading rotor that can be adjusted up and down, and by moving the snow resistance plate up and down according to the snow quality, the degree of crushing can be freely adjusted to create a clean slope surface. It is a technical challenge to provide a snow crushing structure for a ski slope leveling device that can perform fine leveling.

[Means to solve the problem]

In the slope leveling device b connected to the rear of the slope leveling vehicle a via a traction connecting rod 1, a rotor support machine having a width approximately equal to the width of the slope leveling vehicle a is attached to the connecting frame 2 connected to the traction connecting rod 1. Frame 5
A drive grading rotor 6 is mounted between the left and right side walls 4 of the rotor support frame 5, and a mounting shaft 7 is mounted between the side walls 4 at the rear of the drive grading rotor 6. A base plate 8 is provided to protrude diagonally downward, a guide plate 9 is vertically provided near the rear of the top plate 3 located behind the drive leveling rotor 6, and a snow resistance plate 10 is provided in the width direction of this guide plate 9. Provided with vertical adjustment.

[Effect]

FIG. 1 shows the ground leveling state, where the driving leveling rotor 6 crushes and levels the slope surface 11, and the leveled slope surface 11 is further finished by the leveling plate 8.
I will do the final leveling.

In this case, if it is fresh snow or light snow that does not require much crushing, the snow resistance plate 10 is raised as shown by the solid line in FIG.
If the gap 12 is maintained large, snow will be easily discharged from this gap 12, and a large amount of crushed snow will be discharged rearward at any time.

On the other hand, when wet snow or hard snow needs to be crushed finely, the snow resistance plate 10 is lowered as shown by the imaginary line in FIG. 2 to keep the gap 12 between the tip 10a and the slope surface 11 small. Then, since the snow cannot be discharged unless it is crushed into small pieces, it is finely crushed until it can be discharged and is discharged from the gap 12.

〔Example〕

The rotor support frame 5 is provided so as to be adjustable in angle with respect to the connection frame 2, and its operation is performed by a hydraulic cylinder for snow compaction.

The mounting shaft 7 is rotatably provided so that the degree of snow compaction of the finishing ground plate 8 can be changed, and 14 is a hydraulic cylinder for adjustment.

The snow resistance plate 10 has adjustment holes 15 drilled at regular intervals in the width direction, and bolts 16 are inserted through the adjustment holes 15 and screwed into nuts 17 fixed to the rear surface of the guide plate 9. The figure shows a case in which the snow resistance plate 10 is adjusted by loosening the snow resistance plate 16 in the vertical direction.

In the figure, 13 is a hydraulic motor.

[Effect of idea]

Since the present invention is configured as described above, new snow is immediately crushed and discharged by moving the snow resistance plate 10 in the vertical direction according to the snow quality and adjusting the gap 12 between the snow resistance plate 10 and the slope surface 11. However, in the case of wet snow or hard snow, it is crushed into small pieces and discharged backwards, so that the slope surface 11 can be finished and leveled as neatly as fresh snow.

The adjustment of the snow resistance plate 10 is not troublesome at all because it is only necessary to adjust it according to the snow quality before the work, and it has practical effects such as excellent workability.
