Description

[Detailed explanation of the invention] [Industrial application field] This invention is useful for loading snow during snow removal onto trucks, throwing snow over high fences over long distances, and transporting this machine by truck. This relates to a snow removal device for a small snow blower whose upper snow removal tube part can be removed and placed so that the long snow removal tube does not get in the way when the snow removal machine is stored in a hangar.

[Conventional technology]

As disclosed in Japanese Utility Model Application No. 55-96913, it is known to extend the length of a rotating snow removal tube by installing an additional tube upright thereon.

Adding a supplementary tube to a snow shovel that rotates in this way may cause the snow shovel to become clogged with snow, and depending on the stopping position of the snow shovel, the aircraft may get in the way and make it difficult to reach inside the snow shovel. can't be inserted, making it difficult to fix snow jams.

[Problem that the invention attempts to solve]

This invention fixes the lower snow removal tube in a state where it is easy to fix snow blockages when the snow removal tube is set up high, and rotates the upper snow removal tube to make it easier to fix snow blockages in the snow removal tube. In addition, the present invention proposes a snow removal device for a small snow blower that can be rotated in the same way even if the fixed lower snow removal tube is removed and shortened.

[Means for solving problems]

The 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, and a snow shovel 4 is protruded from the rear upper part of the auger case 3, and the auger 2 scrapes snow into the auger case 3. In a small snow blower that blows accumulated snow from the tip of a snow blower tube 4 using a blower installed at the rear of the auger case 3, the long snow blower tube 4 is separated at the middle and the upper snow blower tube 4a and opening/closing door are removed. The mounting collar plate 15 provided at the lower end of the lower snow removing pipe 4b is superimposed on the mounting collar plate 18 provided at the upper part of the mounting pipe 5, and the bolts 16 and nuts are A mounting flange plate 1 identical to the mounting flange plate 15 is detachably attached to the upper end of the lower snow removal pipe 4b by a fixing means such as 17.
4 is provided, and an upper snow removal pipe 4a is mounted on this mounting collar plate 14.
Overlap the mounting flange plate 13 to attach the bolts 16,
It is removably fixed by a fastening means such as a nut 17, and a gear disc 10' provided at the lower end of the upper snow removal tube 4a is engaged with this mounting collar plate 13, so that the upper snow removal tube 4a can be freely rotated. A gear 10 is provided on the gear board 10', a gear 8 that meshes with the gear 10 is provided on the upper end of a rotating shaft 9 that is mounted along the lower snow removal tube 4b, and a gear 10 is provided on the lower end of the rotating shaft 9. gear 8'
A worm gear 12 that meshes with this gear 8' and also meshes with the gear 10 is provided at the tip of the rotating handle 11 that is rotated by a rotating operation part 19 provided near the handle 7 of the self-propelled aircraft 1. It is characterized by the fact that

〔Example〕

The snow shovel 4 in the drawing shows a case where the length is 2 to 2.5 m, which is about twice as long as a normal snow shovel.

The upper snow removal tube 4a in the drawing is formed in the shape of a U-shaped gutter, and is provided with an adjustment plate 20 at its tip to adjust the blowing angle, and the lower snow removal tube 4b is formed in a cylindrical shape, with one side extending in the longitudinal direction. An opening/closing door 6 is provided to take out the clogged snow.

The lower snow removal tube 4b in the drawing is removably installed on the mounting flange plate 18 of the attachment tube 5, so this lower snow removal tube 4b
A case is shown in which the upper snow removal tube 4a can be used as a low snow removal tube 4 by taking it out from the mounting tube 5 and fixing the upper snow removal tube 4a on the mounting flange plate 18 of this attachment tube 5.

The snow removal tube 4 is rotated by a rotating handle 11.
The worm gear 12 also meshes with the gear 10, so that it can be operated by rotating the rotating handle 11.

[Effects of the invention] Since the invention is configured as described above, if the upper snow removal tube and the lower snow removal tube are fixed and used as a long snow removal tube, the snow removal tube will be higher than a normal snow removal tube. Since it draws a large parabola, it can blow snow farther and clear the snow.

Furthermore, the long snow shovel makes it convenient for piling snow high or loading it onto a dump truck with a high platform, and it also allows snow to be dumped over fences that are higher than before.

In addition, if a long snow removal tube is not required, since the mounting flange plates 14 and 15 at the upper and lower ends of the lower snow removal tube are the same, the mounting flange plate 13 of the upper snow removal tube can be replaced with the attachment flange plate 13 of the upper snow removal tube. 18, so if you remove the lower snow removal tube and attach the upper snow removal tube directly to the mounting tube, it becomes a short snow removal tube that is about half the length of a normal snow removal tube, and can clear snow over long distances. This means that snow removal work can be done easily without having to use a long snow shovel when removing snow from areas where it is not necessary.

At this time, the connection between the upper snow removal tube and the lower snow removal tube is a simple fastening method that involves simply fastening the mounting flange plate with bolts and nuts, so they can be easily attached and detached at any time. The same applies even during snow removal work.

In addition, since the worm gear provided at the tip of the rotating handle is provided so as to mesh with both gears 8', 8 and gear 10, if the upper snow removal tube and the lower snow removal tube are added to form a higher height, the worm gear and gear 8', a rotation shaft, gear 8, and gear 10, the upper snow removal tube can be rotated.

Further, when the lower snow removal tube is removed, the worm gear can directly rotate only the upper snow removal tube via the gear 10.

Furthermore, if the upper snow removal tube and the lower snow removal tube are added together to form a higher snow removal tube, the interior may become clogged with snow.

In this case, the present invention is designed so that the lower snow removal tube is fixed without rotating, and even before the upper snow removal tube rotates, the opening/closing door of the lower snow removal tube is placed in a position where it is easy to insert a hand or a stick into the opening/closing door of the lower snow removal tube. When fixed and fixed, it becomes a snow removal device for a small snow blower that makes it easy to fix snow jams.
