JPS6035611Y2 - Height adjustment device for small snow blowers - Google Patents

Description

[Detailed description of the invention] The present invention relates to a height adjustment device for a small snow blower that can smoothly and quickly adjust the height of the snow removal working part even while work is in progress, and one embodiment will be shown. The configuration will be described in detail with reference to the accompanying drawings as follows.

The middle part of the working machine 5, which has a snow removal working part 3 at the front and a handle 4 protruding from the rear part, is pivotally connected to the front part of the traveling machine body 2 on which the crawler track 1 is attached, and the rear part of the traveling machine body 2 is connected so as to be able to freely vibrate. Adjustment rod 6
On the other hand, a connecting plate 7 is protruded from the rear of the working body 5, and a slide hole 8 into which the adjusting rod 6 is loosely inserted is bored in the connecting plate 7. A pressure spring 9 is wound around the adjusting rod 6 to elastically bias the working machine 7 upward, and a stopper 10 is screwed onto the upper part of the adjusting rod 6 to abut against the connecting plate 7 and prevent downward vibration of the front part of the working machine 5. It is something.

In the small snow blower shown in this figure, an auger 11 for removing snow is mounted on a shaft in a snow removal work section 3, and this auger 11 is rotated by a prime mover 12, and the rotation of the auger 12 removes snow in front of the auger case 13. The introduced snow is removed by being thrown off from a snow removal pipe 14 by the rotational force of a blower installed in the rear of an auger case 13.

This figure also shows the drive shaft 1 of the drive wheel 15 of the traveling aircraft 2.
A working machine 5 is pivotally attached to 6 so as to be able to vibrate vertically.

This figure also shows the idler shaft 1 of the idler wheel 17 at the rear of the traveling aircraft 2.
The lower boss portion 19 of the adjustment rod 6 is pivotally connected to the adjustment rod 6.
is pivotally mounted and erected at the rear of the traveling body 2.

Reference numeral 20 indicates color.

Since the present invention is configured as described above, when the stopper 10 is rotated in the loosening direction or the tightening direction, the traveling machine body 2 vibrates. If the stopper 10 is moved downward against this, the snow removing section 3 at the front of the traveling machine body 2 will vibrate away from the ground, and conversely, by rotating the stopper 10 in a relaxed manner, the stopper 10 will be moved upward. If moved, the snow removal section 3 at the front of the traveling body 2 will vibrate in close proximity to the ground, and the height of the snow removal section 3 can be easily adjusted.

In particular, since the pressure spring 9 presses the rear part of the work machine 5 and biases the front part of the work machine 5 in a direction to vibrate downward, the operator can press the handle 4 when turning or retreating. If the front part of the work machine 5 is lifted upward and vibrated by pointing it downward and pushing it down against the pressure spring 9, it will be possible to change direction, turn, and retreat more smoothly, making it extremely light. Moreover, snow removal work can be carried out efficiently.

Furthermore, due to the presence of the pressing spring 9, the rear part of the traveling body 2 is always pressed against the ground, and this ensures that the ground contact pressure between the crawler track 1 and the ground is always maintained. The traction force of the traveling body 2 can be enhanced, and snow removal work can be performed more reliably.

As described above, the present invention provides a height adjustment device for a small snow blower that has excellent practical effects such as being able to quickly and properly adjust the height of the snow removal working section even during operation. will be provided.
