Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present application is intended for snow removal and snow removal on roads in a winter period, and evacuates snow accumulated on an ordinary road to the rear by a rotary car. It is a method of skipping snow directly on a loaded truck.

This type of snow removal and snow removal has been widely used as a truck loading by a rotary snow plow, but the above-mentioned method has a structural problem and has not been put to practical use at present.

[Prior Art] Conventionally, this type of device is as follows.

In the snow removal period in winter, the snow that has fallen in the city is piled up on the side of the road facing the private house with the snow removed each time.

However, the snow is periodically removed (taken out to a snow dump) by workers of a rotary snowplow and a truck.

The conventional technology uses a method to remove snow that has been scraped by a rotary snow plow, and the snow that has been thrown laterally through a chute runs parallel to the rotary snow plow at the same speed as the truck. And loading.

[Problem to be Solved by the Invention] The conventional technology has the following problems.

There are four lanes and two lanes on the road. Conventional techniques are sufficient if the lane is four lanes, but there are many problems with this method in snow removal on a two-lane road.

As a problem, snow removal work cannot be performed unless the vehicle is closed for a certain period of time in both lanes when working in the snow removal section.

 Moreover, during daytime work, there are many obstacles to traffic and it is impossible.

Currently, we are considering night work, but we are worried about the lack of safety, high costs, and the complaints of residents due to noise. is there.

The point is that snow cannot be removed smoothly unless two lanes are secured for conventional snow removal.

The present application has been made in view of such problems of the related art, and has as its object to provide the following.

The purpose of the present application is to allow the vehicle to travel in one lane on each side of the two lanes for the snow removal work, and to allow the worker of the rotary car and the truck to perform the snow removal work in only the remaining one lane.

A long chute is required to use a rotary snowplow to fly the snow right behind and load it on a truck that is evacuated backwards, but if the chute is not supported in the middle, the long chute must be placed behind. Can not.

(1) However, since the rotary snow removing device and the vehicle body are connected by a pin structure, and a bending angle is always generated during traveling, this type of device is generally considered to be structurally impossible. By providing the support device with the chute support swivel table on the side of the present application, it is possible to travel while supporting the chute in the middle, and to discharge snow to the rear track via this chute, so that the snow removal work only in one lane Can be solved.

(2) This rotary snowplow is composed of a rotary snowplow and a traveling vehicle, and is connected to a rotary snowplow by a pin structure.

In addition, the rotary snow removal device and the traveling vehicle have separate driving devices.

The traveling vehicle is a bucket-type wheel loader generally used for civil engineering work, and its bucket is removed during winter to transform it into a rotary snowplow.

This left and right hydraulic cylinder 5E3
The upper end of the chute 3 is rotatably connected to a chute support fixing pin 3A mounted on the upper surface of the long chute 3 in a direction perpendicular to the longitudinal direction of the long chute.

[Action] The thing of the present invention acts as follows.

First, as shown in FIG. 8, it is possible to freely change the α ゜ angle caused by the longitudinal movement of the chute by the operation of the chute support 5E and to generate an arbitrary turning angle β ゜ based on the chute turning center point h generated during turning. Can control.

The turntable 5D can arbitrarily turn between the β ゜ angles while centering on the chute turning center point h by the guide rail 5C.

On the upper surface of the turntable 5D, two hydraulic cylinders 5E3 for receiving the long chute 3 are fixed to the bearing 5E1 with pins 5E2, and the long chute 3 is a long chute generated by raising and lowering the rotary device as shown in FIG. the longitudinal range of movement amount l ₁ of chute hydraulic cylinder 5E3 can move arbitrarily α ° rotation angle range.

Further, when the traveling vehicle 2 forming the vehicle portion of the rotary snowplow advances in the work situation shown in FIG. 6 and the turning angle of the traveling vehicle bending center point p originates from the bending vehicle center point p by operating the steering wheel, the chute support is provided. The hydraulic cylinder 5E3 connected by the fixing pin 3A can rotate in the β ゜ range together with the swivel 5C.

As a result, it is possible to simultaneously operate the steering wheel while moving the long chute 3 back and forth.

At this time, even if the traveling vehicle bending center point p does not coincide with the chute turning center point h (even if the two points do not overlap in a straight line), the movements of both points can be linked.

That is, although it is theoretically ideal that the vehicle turning center point h coincides with the chute turning center point h configured at the same or different position from the running vehicle bending center point p,
It may be practically difficult to project the vehicle bending center point p on the driver's seat and to match the two points.

Therefore, in the present application, a configuration in which the two points can be linked even if they do not coincide with each other is adopted.

Referring to FIG. 4, the chute support fixing pin 3A is connected to the hydraulic cylinder 5E with the chute end fulcrum d as a base point.
By pushing up with 3, the snow discharge port can be changed upward.

Therefore, the discharged snow g has a feature that the height of the loaded snow g can be adjusted toward the truck bed.

FIG. 1 shows the state of snow removal and snow removal work on a road.

The snow is picked up by 1B, discharged from the snow discharge port 4 through the long chute 3 toward the rear truck bed, and directly injected.

In this rotary snow plow, a rotary snow plow 1 and a traveling vehicle 2 are connected by mounting pins 6.

For this reason, during the operation, the steering wheel is turned on the traveling vehicle 2 side as shown in FIGS.
Or produce more bending angle theta, also adjusted amount of the movement amount f by raising and lowering the rotary snow removing device, although or cause a longitudinal movement amount l ₁ of long shot shown by FIG. 5, the chute body of the rotary snow removing apparatus Snow removal and snow removal can be performed while supported by the chute end fulcrum d and the chute support 5E.

Referring to FIGS. 13 to 15, the operation when the traveling vehicle is bent is as follows.

The chute turning center point h installed on the turntable 5 fixed to the driver's seat ceiling 2A is defined as h ′ on the horizontal plane when the traveling vehicle 2 is bent at an angle θ with the traveling vehicle bending center point P as a fulcrum. change in position of moving to point l ₄ appears.

This change is that R moves in the horizontal plane to R ', and accordingly the Q of the hydraulic cylinder 5E3 makes an arc movement about Q and R' around R and R ', respectively.

In addition, it is linked with the circular movement around the chute end fulcrum d of the long chute 3.

Therefore, the change amount l ₄ of the horizontal motion would be replaced in the vertical direction of the change amount C of long shot 3, long shot 3 continuously follow the bending of the traveling vehicle 2.

Referring to FIG. 16, the operation when the rotary snow removal device is moved up and down is as follows.

Increasing the rotary snow removing device 1 chute end fulcrum d moves to d ', l, position change of the l ₃ appears.

This change is absorbed by the circular motion of the Q point of the hydraulic cylinder 5E3 within the range of α ゜.

Here, Q and R are arbitrary points on the rotation fulcrum of the hydraulic cylinder 5E3.
