Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a snow-throwing prevention device for a snow blower, which includes a deflector portion at the tip of a snow-throwing tube that is adjustable in vertical rotation angle.

[Conventional technology]

Generally, a snow blower uses a blower to blow up snow that has been scooped up by an auger-shaped scraping blade, and throws the snow in a predetermined direction through a snow throwing tube A, as shown in Figure 4.
At the tip of the snow throwing tube A, a deflector part B is installed via a hinge C to adjust the snow throwing angle and the snow throwing distance. The rotation angle is adjusted.

[Problem that the invention attempts to solve]

By the way, depending on the quantity and quality of the snow, the snow may scatter laterally from the angle-adjusted deflector part B, making it impossible to concentrate the snow on the target snow-throwing location (distance). There was a problem. In particular, there was a strong tendency for the snow to scatter when the amount of snowfall was small.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems, and is a snow removing tube in which a deflector part is provided at the tip of the snow throwing tube, the vertical rotation angle of which can be adjusted. The deflector section is characterized in that it is divided into sections so that it can be rotated in both the left and right directions as well as in the vertical direction.

[Effect]

With the above configuration, the thrown snow scattering prevention device of the present invention prevents the thrown snow from spreading laterally and throws the snow to the target position. Additionally, it can be rotated in both left and right directions depending on the amount of snow thrown.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a snow-throwing tube installed to communicate with a blower (not shown), and a deflector base 3 is attached to the tip of the snow-throwing tube 1 via a hinge 2 in the vertical direction. It is supported so that the rotation angle can be adjusted. A deflector tip 4 is supported at the tip of the deflector base 3 via a hinge 5 so as to be rotatable in the left-right direction. The deflector tip 4 consists of a left tip 4a and a right tip 4b, each of which is hinged to the deflector base 3 via a hinge 5. Then, the left and right tip portions 4a, 4
A spring 6 is installed at the tip of the upper surface of b.
The distal end sides of both distal end portions 4a and 4b are urged to approach each other. The spring pressure of the spring 6 is such that when the amount of snow passing through the deflector tip 4 is small, the tips of the left and right tips 4a and 4b are kept close to each other, and the amount of snow passing through the deflector tip 4 is If there is a lot of pressure, the left and right tips 4a, 4b
The tips are set so that they are spaced apart. In the case of preventing scattering of snow with such a configuration, when the amount of snow shoveled by the auger is small due to the snowfall amount, the running speed of the snow blower, etc., the left and right tips 4a and 4b of the deflector tip 4 are With the leading ends kept close to each other (as indicated by the imaginary lines in Figure 1), the snow is ejected with good direction through a narrow gap, and is thrown to the target location. If the amount of snow shoveled by the auger is large, the tip of the deflector 4
The left and right tips 4a, 4b of the snow are pushed apart by the passing snow against the elastic force of the spring 6 (solid lines in FIG. 1), and the snow is thrown to the target location without scattering. The degree of opening of the left and right ends 4a, 4b in the left and right direction at this time is automatically adjusted depending on the amount of snow passing therethrough. Further, the angle of the entire deflector in the vertical direction is adjusted in advance by adjusting the deflector base 3 using a remote control device or the like depending on the amount, quality, etc. of snow. The second embodiment of the present invention shown in FIG.
Adjust the opening degree of the left and right tips 4a and 4b in the left and right direction.
A pair of gears 8, 8 are provided at both end portions 4a, 4b so as to mesh with each other via shafts 7, 7, and the left end portion 4
A pin 9 provided at the part a is operated by an operation wire (not shown). In this case, the spring 6 is biased so that the left and right tip ends 4a and 4b approach each other, as in the case of FIG.
With the rotation of a, the right tip 4 is
b is configured to rotate relatively. In the case of this second embodiment, the opening degree of the left and right tips 4a, 4b is adjusted by remote control or manually using the pin 9 position, depending on the amount and quality of snow to be thrown, to achieve the desired throwing. make it snow. The third embodiment of the present invention shown in FIG.
A Y-shaped operating fitting 10 provided with a Y-shaped slit 10a is attached to the left and right tips 4a and 4b via guide pins 11, 11, a pivot pin 12, and a guide pin 13. An operating wire or operating rod (not shown) is connected to an operating hole 14 provided at the base end for operation. In the case of this third embodiment, the Y-shaped operating fitting 1
By moving 0 back and forth, the left and right tips 4a, 4
The opening degree is adjusted by rotating b in the left-right direction about the pivot pin 12.

[Effect of the idea]

As explained above, according to the snow blowing prevention device for a snow blower of the present invention, it is possible to adjust the rotation of the deflector part in the vertical direction as well as the opening degree in the left and right directions, so that snow is not thrown from the deflector part. amount of snow,
Depending on the quality, especially by adjusting the left and right opening, it is possible to prevent snow from scattering and to throw snow at the target location. Further, the tip of the deflector is divided so as to rotate in the left and right directions, and its opening degree can be adjusted automatically, remotely, or manually.
