Description

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

The present invention relates to side plates of a snow removal auger in a snow blower, and particularly to left and right side plates to which one end of the auger is fixed.

[Conventional technology]

As shown in Figure 3, at the front of the aircraft in the direction of travel,
For example, a snow blower has a rotating shaft C horizontally mounted on both left and right sides with side plates A attached via support members B, and one end of a spiral snow scraping auger D is fixed to the left and right side plates A, for example. It is disclosed in Japanese Utility Model Application No. 57-174523. The side plate A of this prior art has a snow scraping notch E formed on its outer circumferential surface, and a snow scraping piece F is fixed and attached to the position of this notch E.

[Problem that the invention attempts to solve]

In the prior art described above, it is necessary to separately manufacture the scraping piece F and separately weld it to the side plate A, which increases the manufacturing cost. In addition, since the side plate A is formed of a ring-shaped flat plate and the scraping piece F is fixed to the side surface, the side plate A
There was also a problem in that the scraping piece F created a large resistance when rotating as the machine moved forward and scraping snow, reducing the scraping performance.

[Means to solve the problem]

Therefore, in order to solve the above-mentioned conventional problems, the present invention has been developed by horizontally mounting a rotating shaft with side plates attached to both the left and right sides at the front of the aircraft in the direction of travel, and attaching the rotating shaft to the left and right side plates. In a snow blower in which one end of a spiral snow scraping auger is fixed, the side plate is curved so that the width is wide at the front end in the rotation direction and gradually narrows at the rear end in the rotation direction. A plurality of pieces are connected to form an annular shape, and the front end of one of the side plate pieces and the rear end of the other one are overlapped in order so that the rear end is on the inside, and the side plate The outer periphery of the side panel piece is characterized by forming a stepped portion corresponding to the difference in width between the front end and the rear end of the side panel piece, and the inner periphery is formed to be circular.

[Effect]

With this configuration, the side panel of the present invention not only improves the raking performance, but also improves the raking performance on the inside of the turn when the aircraft turns while performing snow removal work, and improves the turning performance. It is something to do.

【Example】

Hereinafter, an embodiment of the present invention shown in FIGS. 1 and 2 will be described. In the figure, reference numeral 1 denotes a rotating shaft mounted horizontally at the front of the body of a snow blower (not shown) in the direction of movement, and both left and right sides of this rotating shaft 1 (one is not shown).
A side plate 3 is attached to the side plate 3 via three supporting members 2. One end of two spiral snow scraping augers 4, 4 is fixed to the inner surface of this side plate 3, and the other end of this auger 4 extends to the center of the machine body, and It is connected to a blower and a snow removal pipe (not shown) installed in the snow pipe. Furthermore, the left and right side panels 3 are symmetrically constructed. The side plate 3 has three side plate pieces 3 that are curved in an arc shape so that the front end 5 in the rotation direction is wide and the rear end 6 in the rotation direction is gradually narrower.
A, 3a, 3a are connected in a circular ring.
In addition, the side plate 3 is constructed by sequentially overlapping and welding the front end and rear end of each side plate piece 3a so that the rear end faces inside, and then attaching the rear end to the support member 2.
It is welded and fixed. A stepped portion 7 is formed on the outer peripheral edge of the side panel 3, and the step portion 7 is formed by the difference in width between the front end 5 and the rear end of the side panel piece 3a, and the inner peripheral edge 8 of the side panel 3 is circular. The side plate pieces 3a are connected in this way. Note that the snow-shaving auger 4 has an intermediate portion supported on the circumferential surface of the rotating shaft 1 via a support 4a. In such a configuration, when the snow blower moves forward and drives the rotating shaft 1 to rotate the side plate 3 and snow scraping auger 4 in the direction of the arrow, accumulated snow is removed by the snow scraping auger 4. The snow is scraped and scraped, and sent to the center of the machine by the feeding action of the auger 4, where it is sucked in by a blower and thrown far to the side of the snow shovel. During this snow removal work, the snow in front of the side plate 3 is scraped off by the stepped portion 7, and guided by the side surface of the side plate 3a, which is spirally inclined, to the auger 4 side. The snow is scraped off by the auger 4 and sent to the center along with the snow that has been scraped by the snow itself. Therefore, the snow removal and raking work at both ends of the rotating shaft 1 can be performed efficiently, and especially when the aircraft is turned while performing snow removal work, the snow removal from the inner part can be performed efficiently. Improves performance.

[Effect of the idea]

As explained above, according to the side panel of the snow removal auger in the snow blower of the present invention, the plurality of side panel pieces 3a constituting the side panel 3 are arranged such that the front end and the other rear end are connected to the rear end. Since the stepped portions 7 are formed on the outer periphery of the side panel, and the inner periphery 8 is formed in a circular shape, the side panel pieces 3a can be overlapped together with the stepped portion 7 by simply splicing the side panel pieces 3a together. can be formed in a spiral shape facing inward, improving the scraping and raking performance despite its simple configuration.In addition, when the aircraft turns, snow removal from the inside of the turn is performed with high efficiency, improving turning performance. will improve. Furthermore, the structure is simple, the production cost is low, and the resistance is low.
