Description

[Detailed Description of the Invention] The present invention includes an engine and a gear case at both ends of the operating rod, snow removal blades that are horizontally supported on both sides of the gear case and rotated by the drive of the engine. The present invention relates to a snow remover equipped with a guide cover that covers the snow remover blades and guides the scattered snow.

Conventionally, in this type of snow blower, the snow removal blades have been formed into separate structures for the left and right sides, as shown in Figures 7 to 10, and when they are made of synthetic resin, two types of expensive metal are used. It required molds and two types of parts in stock.

That is, as shown in FIGS. 8 and 10, when the lengths of the left and right rotation axes are equal, the left snow removal blade shown in FIG.
Although it is possible to replace the snow removal blade on the right side shown in Figure 0 and engage and fix it to the rotation shaft on the right side, it is possible to replace it with the snow removal blade on the right side as shown in Figure 0. The direction is reversed, making it impossible to shovel snow properly.

In this invention, each snow removing blade is formed in a symmetrical shape and can be engaged and fixed to both ends of the rotating shaft interchangeably without changing the direction of rotation of the snow removing blade itself. By using snow removal blades on the left and right sides, it is possible to reduce the manufacturing cost of the mold and reduce the number of parts in stock, thereby reducing costs.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 6, reference numeral 1 denotes a snow removal section, which is connected to an engine 5 via an operating rod 3. A transmission shaft 7 for transmitting the power of the engine 5 to the snow removing section 1 is provided to penetrate inside the operating rod 3 . 11 is a grip portion fixed to the operating rod 3;
Reference numeral 3 denotes a grip provided at the end of the handle 15 fixed to the operating rod 3. The snow removal section 1 is constructed as follows. That is, 17 is a gear case, and one end thereof is provided with an engaging portion 19 that detachably engages with the end of the operating rod 3. Reference numeral 21 denotes a bolt that fixes the engaging portion 19 to the operating rod 3 via a notch (not shown) which is formed by cutting out the end of the engaging portion 19 in the axial direction. 25 is a bevel gear that is pivotally supported by a bearing 27 inside the gear case 17, and 29 is an engaging body that is threadedly engaged with the boss portion 31 of the bevel gear 25, and the bearing 27 is held between the bevel gear 25 in the axial direction. The engaging body 29 is removably engaged with a square shaft portion 33 at the end of the transmission shaft 7. 35 is horizontally attached to the gear case 17, bearings 37, 3
7, and a bevel gear 39 that engages with the bevel gear 25 is fixed thereto. Reference numeral 41 denotes a snow removal blade made of synthetic resin, which is fixed to one body by three blade plates 47, 47, 47 between circular side plates 43, 45 facing each other on the inside and outside, and has a rotating shaft 35 in the center. A shaft cylinder 51 equipped with a fitting hole 49 to be fitted is provided in one body, and a female metal threaded body 53 is embedded in the central position of the shaft cylinder 51 during molding, and the tip of the rotating shaft 35 is It is screwed into the threaded portion 55. Note that the blade plate 47 is provided so as to be appropriately inclined with respect to the circumferential surface so as to scoop up and shovel snow with respect to a predetermined rotational direction of the snow removal blade 41 itself. 57
A guide cover is fixed to the engaging part 19 by screws 59, and covers the rear, sides, and bottom of the snow removal blade 41, and guides the snow scattered by the snow removal blade 41 diagonally forward and upward. be. 61 is the guide cover 5
This is a snow scraping board installed at the bottom tip of 7.

In the above configuration, the power of the engine 5 is transmitted through the transmission shaft 7, the bevel gear 25, the bevel gear 39,
Through the rotating shaft 35, the snow removing blades 41, 41 on both sides are rotated and driven in the direction of arrow A in FIG. When the operator grasps the grips 11 and 13 with both hands and pushes the snow removal unit 1 forward with the snow shovel 61 in contact with the ground, the snow on the ground is cleared by the rotating snow removal blades 41 on both sides and guided. It is guided by the cover 57 and is scattered and ejected diagonally forward and upward.

Further, each of the snow removing blades 41 is formed in a left-right symmetrical shape, and is formed so that the left and right sides can be engaged and fixed to both ends of the rotating shaft 35 without changing the rotation direction of the snow removing blades 41 themselves. For example, remove the snow removal blade 41 on the left side in FIG. 2, fit the fitting hole 49 on the left side to the rotating shaft 35 on the right side, and screw it into the female threaded body 53 from the opposite direction to fix it. is possible, and the direction of the blades is not reversed.
Snow removal performance does not deteriorate. Since the present invention has the configuration as described in the claims, it is possible to reduce the number of molds manufactured, reduce the types of parts preparation, and reduce manufacturing costs.

In addition, FIG. 6 shows another embodiment, in which female threaded bodies 65 and 67 are embedded symmetrically in the side plates 43 and 45, respectively.

Note that FIGS. 7 to 10 show the conventional snow removal blade, and FIGS. 7 to 8 show the snow removal blade on the left side, and FIGS. 9 and 10 show the snow removal blade on the right side.

The snow removal blade 41 is fixed to the rotating shaft 35 by a bolt 63 that is screwed onto the tip of the rotating shaft 35 that fits into the central shaft cylinder 51. In order to easily fix the snow removing blade 41 to the rotating shaft 35 with the bolt 63, the left and right snow removing blades 41, 41 have different structures and are provided symmetrically.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
