Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow remover, in which the grader plate can be easily swung, and the angles of auxiliary plates provided on both sides of the snow remover can be changed according to the swinging motion of the grader plate. Is to provide.

[0002]

[Prior art]

 Conventional snow blowers equipped with an engine and other drive devices consist of a grader plate attached to the work vehicle body, and most of the special snow blowers were manufactured for the purpose of removing snow from the beginning.

However, such a snow remover is used only during a snowfall season, and a working vehicle body equipped with an engine and other drive devices can be used outside the snowfall season, but is left unattended. It has been left alone.

Therefore, a tractor or a tiller that has been conventionally used as an agricultural machine can be equipped with a snow removal tool so that a working vehicle body including a drive device such as an agricultural machine can be effectively used. Although it has been tried in some cases, in that case, it has not been done until the grader plate is attached to the vehicle body and easily pivotable. Of course, the angle of the auxiliary plates provided on both sides of the grader plate cannot be changed according to the swinging motion of the grader plate.

[0005]

[Problems to be solved by the device]

 By the way, in the snow removal work, it is necessary to remove the snow by going straight on the road surface or by the side of the road according to the amount of snow. Such work is performed by rotating the grader plate, but when the grader plate is attached to and detached from the working vehicle body equipped with the drive device, it is technically difficult to easily rotate the grader plate. Many.

The present invention is intended to solve the above-mentioned drawbacks of the conventional example. In addition, the grader plate is attached to and detached from the vehicle body equipped with the drive device, and the grader plate is easily rotated within a predetermined angle range. It is intended to provide a snow blower that can be moved and can also change the angle of auxiliary plates provided on both sides of the grader plate.

[0007]

[Means for Solving the Problems]

 That is, the snow blower of the present invention has a grader plate rotatably mounted on a working vehicle body equipped with a drive device, and a grader plate pivotally mounted on both sides of the grader plate. A pair of auxiliary plates that are interlocked and interlocked with each other, and an operation boom stretched between one end of at least one of the auxiliary plates and a support shaft provided on the side of the bearing portion of the working vehicle body. The auxiliary plate is characterized in that the angle with respect to the grader plate is changed according to the rotation of the auxiliary boom, which is restricted by the length of the operating boom with the support shaft as the fulcrum.

[0008]

[Action]

 Since the snow removal machine of the present invention is configured as described above, it is possible to change an agricultural machine or the like into a snow removal machine with one touch by simply attaching the grader plate and the screw screw to the work vehicle body. Then, by rotating the rotary shaft with the operating means, the grader plate easily rotates within a predetermined angle range, and the angles of the auxiliary plates on both sides of the grader plate are automatically adjusted to an angle that does not allow snow to escape. I can change it.

Further, 6 is a screw screw held by the working vehicle body 2, 7 is a fulcrum near the screw screw 6, one end is movably screwed onto the screw screw 6, and the other end is for operating the grader plate 4. The lever is connected to the rod 8 via a connecting rod 15. A rotating shaft 9 is connected to the screw screw 6, and the rotating screw 9 is rotated by rotating the rotating shaft 9 by an operating means such as a crank type handle 13 provided near the handle 12 of the working vehicle body 2. To do.

Reference numeral 14 is an operation lever for moving the arm 5 attached to the handle 12 up and down, and is used to lift the arm 5 when snow removal work is not performed.

In the figure, 31 is an auxiliary plate, 33 is an operating boom, and 35 is an adjusting screw for adjusting the length of the operating boom 33.

Next, FIGS. 2 to 5 show details of the screw screw 6 portion. That is, both ends of the screw screw 6 are rotatably held by the frame 21 attached to the working vehicle body 2. A fulcrum arm 22 is pivotally attached to one end of the frame 21, and a lever 7 is rotatably held at a tip end of the fulcrum arm 22 at an appropriate position in an intermediate portion. One end of the lever 7 is movably screwed onto the screw screw 6, and the other end is axially attached to an operating rod 8 connected to the grader plate 4 via a connecting rod 15. Reference numeral 23 is a connecting portion for rotating the screw screw 6 and the rotating shaft 9.

FIGS. 6 to 8 show a rotating mechanism of the grader plate 4, in which an operating rod 8 attached to the rear surface of the grader plate 4 is operated by being connected to a lever 7 of the screw screw 6 to operate the grader plate 4. The plate 4 swings around the bearing 11 part. Auxiliary plates 31 and 31 ′ are pivotally mounted on both sides of the grader plate 4 so that they can swing freely, and a connecting boom 32 is connected between them to interlock with each other. An operating boom 33 is stretched between one end of the auxiliary plate 31 and a support shaft provided on the side of the bearing 11 on the front surface of the arm 5, and the auxiliary plate 31 moves in accordance with the rotation of the grader plate 4. The length of the operating boom 33 with the support shaft as a fulcrum is restricted, and the angle with the grader plate 4 is changed.

That is, when the grader plate 4 rotates to the left, the auxiliary plate 31 makes a small angle with the grader plate 4 (see FIG. 7), and when the grader plate 4 rotates to the right, the auxiliary plate 31 moves. Rotate in a direction to make the angle with the grader plate 4 larger (see FIG. 8). At that time, the other auxiliary plate 31 'rotates in the same direction in conjunction with the auxiliary plate 31'. 34 and 35 are adjusting screws for adjusting the lengths of the connecting boom 32 and the operating boom 33, respectively, and 36 is a stopper for restricting the rotation of the grader plate 4 provided on the front surface of the working vehicle body 2, which is a grader plate. It contacts the operation rod 8 of No. 4 and regulates the rotation of the grader plate 4.
