Description

[Detailed explanation of the invention] This invention not only blows snow away during snow removal, but also eliminates the need for long snow removal tubes when transporting this machine by truck or storing it in a hangar. This invention relates to a snow removal device for a small snow blower that can be folded into two to prevent the snow from falling, and its configuration will be described in detail with reference to the accompanying drawings as follows.

An auger case 3 having an auger 2 is provided at the front of the self-propelled aircraft 1, a snow shovel 4 is provided at the rear upper part of the auger case 3, and the auger 2 scrapes snow into the auger case 3 and scrapes the snow. In a small snow blower that blows snow away from the tip of a snow blower tube 4 using a blower installed at the rear of the auger case 3, the snow blower tube 4 is formed with a total length of 2 to 2.5 m, and this snow blower tube 4 is Attachment frames 9 and 10 are provided at the lower end of the upper snow removal tube 4a and the upper end of the lower snow removal tube 4b by separating it at the middle part, and a thread 11 is provided on one side of the overlapping attachment frames 9 and 10 to remove the snow from the lower part. The upper snow removal tube 4a is provided so as to be foldable with respect to the tube 4b, and the mounting frame 9
The upper snow removal tube 4a is rotatably provided with respect to the mounting frame 9 by means of a support fitting 14 provided in the upper snow removal tube 4a.
The gear 13 provided on the outer periphery of the self-propelled vehicle 1 is engaged with a gear 15 which is rotated by a rotation operation section 6 provided near the handle 5 of the self-propelled vehicle 1 via a snow removal tube rotation mechanism a. It is something.

The upper snow removal tube 4a in the drawing is formed in the shape of a U-shaped gutter, and an adjustment plate 7 for adjusting the blowing angle is provided at the tip thereof, and the lower snow removal tube 4b is formed in a cylindrical shape.
Opening/closing door 8 for removing snow stuck in the length direction of one side
has been established.

The snow removal tube rotation mechanism a shown in the drawing includes a rotation shaft 17 having gears 15 and 16 at both ends attached to one side of the lower snow removal tube 4b, and this upper gear 15 is connected to the upper snow removal tube 4a. It meshes with gear 13 and lower gear 16
A case is shown in which a worm gear 19 which is rotated by a rotation handle 18 of the rotation operation section 6 is engaged with the rotation handle 18, and by rotating this rotation handle 18, the upper snow removal tube 4a is rotated.

In the figure, 20 is a bearing plate, and 21 is a snow shovel fixing fitting.

As mentioned above, this invention makes the snow removal tube 4 about twice as long as the normal snow removal tube 4 (2 to 2.5 m), so the snow removal tube 4 becomes very high and draws a large parabola. This makes it possible to blow snow far away and remove it.

Furthermore, by making the snow removal tube 4 higher, it is convenient when stacking snow high or loading it on a dump truck with a high platform, and it is also possible to remove snow by climbing over a wall.

If the snow removal tube 4 is long, it has the disadvantage that it gets in the way when it is transported on a truck or stored in a hangar.

In this regard, the present invention separates the snow removal tube 4 at the middle to form an upper snow removal tube 4a and a lower snow removal tube 4b, so that the upper snow removal tube 4a can be folded back to the lower snow removal tube 4b. Because it is provided, when not in use, the upper snow removal tube 4a can be folded back downwards to open the snow removal tube 4.
The snow removal tube 4 becomes 1/2, that is, the normal length, so that the snow removal tube 4 does not get in the way and can be easily transported and stored by truck.

Moreover, since this folding is also done by the screw 11, the folding is done extremely smoothly, and the mounting frame 9 at the lower end of the upper snow removal tube 4a is not done by fitting the tubes together.
The upper snow removal tube 4a and the lower snow removal tube 4 are fixed by overlapping the mounting frame 10 at the upper end of the lower snow removal tube 4b.
The connection of b is also performed well, and even with the connected snow removal tubes 4, there is no problem with the passage of snow.

At this time, since the upper snow removal tube 4a and the lower snow removal tube 4b are connected, there is a drawback that the upper snow removal tube 4a cannot rotate smoothly. The gear 15 is engaged with the gear 13 of the lower snow removal tube 4b and the snow removal tube rotation mechanism a rotates the gear 15.
Since the gear 13 is forcibly interlocked by the rotation, the upper snow removal tube 4a rotates extremely smoothly, and snow can be removed in a desired direction.

Furthermore, since this rotation operation is also performed using the rotation operation part 6 provided near the handle 5, it can be easily performed by simply extending your hand a little while driving, demonstrating excellent practicality. It becomes a snow removal device for a small snow blower.
