Abstract

PURPOSE:To form flat leveled ground face by providing a vane fluctuating in the width direction of a rotor on a position of a flyingly carrying passage of crushed objects from the uneven ground to be leveled by crushing action of the rotor, between a self running vehicle and the ground leveling rotor. CONSTITUTION:When a snow ground leveling vehicle 1 is run of itself and a ground leveling rotor is driven, the uneven snow ground surface 4 is crushed, and crushed snow is flyingly carried in front of the rotor. By slidably moving a rod 9 due to projection of a cylinder rod, a vane 5 is fluctuated in the width direction of a case body 7, the flying direction of crushed snow is made variable so as to flatten the snow surface. Further, the snow surface 4 is leveled by means of a ground leveling plate 3 so as to be uniformly flattened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground leveling device attached to a slope leveling vehicle or the like.

[0002]

2. Description of the Related Art Conventionally, the applicant of the present invention has an actual utility model of 2-379.
As disclosed in No. 23, an arm rod 6 that pivots with respect to the self-propelled vehicle 1 is pivotally attached to the rear portion of the self-propelled vehicle 1, and the width of the arm rod 6 is approximately equal to the width of the self-propelled vehicle 1. There is proposed a slope leveling vehicle in which the case body 7 is provided, the leveling rotor 2 is mounted on the case body 7, and the leveling plate 3 for smoothing the uneven snow surface 4 is provided at the tip of the case body 7 (hereinafter, simply It is called a conventional example.).

In the structure of this conventional example, the same components as those in the present application are designated by the same reference numerals. In this conventional example, the uneven surface of the uneven snow surface 4 is crushed by the leveling rotor 2, the crushed snow is sent along the inner surface of the case body 7 to the front of the leveling rotor 2, and the leveling plate 3 flattens the snow surface. It is something to do.

[0004]

As a result of various experiments of the conventional example, the applicant confirmed the following problems.

When the unevenness of the snow surface formed on the slope of a ski resort due to the skier's gliding etc. is crushed and smoothed by the ground leveling rotor 2 of the ground leveling vehicle, the conventional ground leveling vehicle is equipped with the ground leveling rotor 2. The blade is welded to the shaft, since the direction of the blade does not change, the flying direction of the crushed snow is fixed, and therefore the crushed snow cannot be fed by the required amount to any recess, There was a drawback that the finish surface of the slope was bad and it took time to work.

In consideration of these problems, the leveling rotor 2
Although the blade angle of the blade of is set to a predetermined angle in advance,
Since the conditions such as the terrain are not fixed, it is impossible to carry out sufficient leveling just by setting the blade angle to a predetermined angle in advance.

Further, the flying distance of snow varies depending on the snow quality (specific gravity / hardness) of the snow surface. Therefore, in this respect also, the blade angle of the grounding rotor 2 is set to a predetermined angle in advance to make the snow surface flat. It is impossible to finish.

As a means for solving this problem, it is conceivable that the blade angle of the leveling rotor 2 can be arbitrarily changed, but it is durable to make the blade to which considerable snow pressure is applied variable. Since it is impossible and the number of blades is considerably large, the structure of the variable mechanism becomes very complicated, and it is technically difficult to change the blade angle of the leveling rotor 2 as a practical problem.

[0009] The present invention has a technical object to provide a ground leveling apparatus attached to a ground leveling vehicle which solves the above problems.

[0010]

The gist of the present invention will be described with reference to the accompanying drawings.

A leveling rotor 2 is provided at the rear of the self-propelled vehicle 1, and a leveling plate 3 is continuously provided at the rear of the leveling rotor 2. The leveling rotor 2 crushes the uneven ground 4 to crush the object to be ground. Of the grounding plate 3, and the grounding plate 3 is used to attach the ground material to the front of the grounding vehicle. The present invention relates to a leveling device attached to a leveling vehicle, characterized in that a blade plate 5 that slides in the width direction of the leveling rotor 2 is provided at the position of the path of the crushed objects to be crushed and transported from the ground 4. .

[0012]

The crushed object crushed by the leveling rotor 2 is sent to the front of the leveling rotor 2 and the flying direction of the crushed object is varied by the blades 5, and the leveling plate 3 is then moved. The uneven ground surface 4 is smoothed and smoothed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings illustrate one embodiment of the present invention and will be described below.

The drawing shows a case where the self-propelled vehicle 1 is a snow grounding vehicle provided with crawler belts 8 having uneven teeth on the left and right in the width direction. Self-propelled vehicle 1
Is not limited to the configuration shown in the drawings.

An arm rod 6 is pivotally attached to the rear portion of the snow leveling vehicle so that the arm rod 6 can be slidably moved with respect to the leveling vehicle, and a case body 7 is pivotally attached to the end of the arm rod 6 to connect the arm rod 6 to the arm rod 6. On the other hand, the case body 7 is slidably provided, and the ground leveling plate 3 is pivotally attached to the tip end of the case body 7 so that the ground leveling plate 3 is slidable with respect to the case body 7.
The leveling rotor 2 is axially mounted on the case body 7.

Reference numeral 21 is a cylinder for moving the leveling plate 3.

On the inner surface of the upper part of the case body 7, a rod 9 is slidably mounted in the width direction of the case body 7 so as to be slidable in the width direction.
A channel-shaped mounting rod 10 is fixed to a predetermined portion of the rod 9, and a protruding piece 12 with a long window 11 is fitted between the upper and lower pieces of the channel-shaped mounting rod 10 and is vertically moved by a shaft pin 13. The piece and the protrusion 12 are pivotally attached. The protruding piece 12 is fixed to the upper cylinder body 14, the shaft rod 15 is inserted in the upper cylinder body 14, and the vane 5 is fixed to the side opposite to the rod 9 near the lower end of the shaft rod 15. Reference numeral 16 denotes a lower cylindrical body fixed to a fixing plate 22 attached to the case body 7. The lower cylindrical body 16 is fitted on the shaft rod 15, and the lower rod body 16 supports the shaft rod 15. .

An oscillating plate 17 is pivotally attached to the end of the rod 9, and one end of the oscillating plate 17 and the end of the rod 9 are provided with a long window 18 of the oscillating plate 17. Pivoted, while rocking plate 17
The other end of the is connected to the cylinder rod 20 of the cylinder device 19.

Incidentally, the sliding of the rod 9 can be designed in various ways such as manual operation, remote operation in the driver's seat of the ground leveling vehicle, automatic operation by linking a small camera for monitoring the snow surface and a microcomputer. Since the present embodiment has the above structure, the cylinder rod
Since the rod 9 slides due to the protrusion / depression of 20 and the blade 5 slides in the width direction of the case body 7 due to the sliding of the rod 9, snow blown by the leveling rotor 2 causes the blade 5 to slide appropriately. As a result, the flight direction can be changed as appropriate, so that the snow surface can be flattened uniformly.
