BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removal direction control device for a snow plow.

[0002]

2. Description of the Related Art In recent years, the traffic volume of automobiles has increased extremely,
Roads that can be moved and transported at high speed such as highways and bypasses are becoming more important. It is needless to say that this situation is the same in the snowfall region and it is essential to remove snow from the snowfall road. Moreover,
On highways, whose main purpose is to be able to drive at high speeds, there is naturally a demand for faster snow removal.

[0003] Conventionally, as a snow removing method on a highway or a bypass, a snow removing truck equipped with a one-way type snow plow as shown in Fig. 5 is run at a high speed to remove snow as shown in the figure. I am collecting. However, there are some areas along the road where snowfall is not allowed, and there is also the problem that facilities such as road signs and emergency telephones will be destroyed by the impact of blown snow. In such places, there is no choice but to remove snow by another method, and speeding up snow removal is not progressing as expected.

[0004]

Therefore, the present invention has been made in view of the above-described problems in the conventional snow plow, and the snow pruning can be continued even in a place where the snow removal is required. It is a technical object to provide a device capable of controlling the direction of snow removal by a simple operation.

[0005]

The technical means adopted by the present inventor to solve the above problems will be described below with reference to the accompanying drawings.

That is, according to the present invention, a forwardly tiltable snow guide 2 having a fulcrum on the lower edge side is provided near the upper edge of the plow body 1 on the snow removal side, and the snow guide 2 is arranged on the back surface of the plow body 1. The gist is that the means for connecting to the installed fluid pressure cylinder 3 and changing and adjusting the snow discharge angle of the snow guide 2 by expanding and contracting the fluid pressure cylinder 3 is adopted.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the accompanying drawings (see FIGS. 1 to 4).

Snow that is normally fitted into an opening provided in a portion of the one-flow type snow plow body 1 near the upper edge of the snow plow side so as to form a continuous surface with the snow discharge surface of the plow body 1. The guide plate 2a, the support bracket 2b protruding from the back surface of the snow guide plate 2a, the bearing 5 fixed to the lower edge of the support bracket 2b, the arm 6 fixed to the bearing 5, and one end The arm 6 is provided with a pin 7, and the other end is provided with a support plate 10 which is erected on the back surface of the plow body 1 with a pin 8,
Each of them is composed of a fluid pressure cylinder 3 which is hinged. The bearing 5 is pivotally supported by a hinge shaft 4 on a stay 9 protruding from the back surface of the plow body 1.

By the expansion and contraction operation of the fluid pressure cylinder 3,
The snow guide plate 2a pivotally moves through the support bracket 2b so that the snow discharge angle can be changed and adjusted.

Next, the operation of the snow removal plow equipped with the snow removal direction control device will be described. In the case of normal snow removal,
By retracting the fluid pressure cylinder 3, the snow guide plate 2a is rotated rearward through the support bracket 2b until it forms a continuous surface with the snow discharge surface of the plow body 1. In this state, it becomes exactly the same as the conventional plow, and it becomes possible to fly the snow removal far (see FIG. 5).

When controlling the snow discharge direction, the fluid pressure cylinder 3 is extended to rotate the snow guide plate 2a so as to project forward through the support bracket 2b. In this state, the snow removal bounced up by the plow body 1 is suppressed by the snow guide plate 2a and the direction thereof can be changed, and the snow can no longer fly far (see FIG. 6). By adjusting the forward tilt angle of the snow guide plate 2a, the snow discharge angle can be controlled appropriately.

The snow removal direction control device of this embodiment is constructed as described above, but the present invention is not limited to the above-mentioned embodiment, and is modified within the scope of the "claim for utility model registration". Is possible.

For example, the shapes of the snow guide plate 2a and the support bracket 2b may be changed, and the plow body 1 may be changed.
It is also within the technical scope of the present invention to allow the vehicle to tilt forward on the upper side of the snow removal side.

[0014]

[Effects of the Invention] As described above with reference to the embodiments, the snow removal direction control device of the present invention is capable of freely changing the direction of the snow removal that is lifted up by the plow by the snow guide, so that the snow removal direction during snow removal running can be changed. Even if you are approaching a snowy section, you can solve problems that have been seen in the past, such as the destruction of emergency telephones due to the impact of blown snow, simply by operating the snow guide. Since it can be operated while the vehicle is running, it will greatly contribute to the speeding up of snow removal, which has been particularly expected recently on highways.
