Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention comprises an engine and a gear case at both ends of an operating rod, and the engine is horizontally supported on both sides of the gear case. The present invention relates to a snow remover including a snow removal blade that rotates when driven by a snow removal blade, and a guide cover that covers the snow removal blade and guides flying snow.

(Prior Art and Problems to be Solved) Conventionally, in this type of snow blower, the snow removal blades are formed by a plurality of blades arranged radially, and the outer edge of the blades is axially were placed in the same position. For this reason, when dealing with heavy snow with high resistance, such as frozen snow or compacted snow, a large load is simultaneously applied to the entire length of the outer edge of the vane, resulting in insufficient engine capacity and the ability to crush the heavy snow. In addition, snow was trapped, resulting in a decrease in snow removal ability.

(Means and effects for solving the problem) In the present invention, snow removal blades are formed by a plurality of vanes arranged radially, and the outer edges of each vane are arranged at different axial positions. By shortening the length of the outer edge of the vane that comes into contact with the snow, it is possible to crush even heavy snow powerfully. It easily crushes snow at different locations and improves snow removal ability.
Furthermore, the structure is simple and the blades can be easily assembled and replaced.

(Example) In FIGS. 1 to 5, 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. 41 is a snow removal blade made of synthetic resin, and is constructed as follows. In other words, 43 is a shaft cylinder made of synthetic resin, and female threaded bodies 4 made of metal are provided at the inner diameter portions of both ends.
5 and 45 are embedded together during molding, and are screwed onto the threaded portion 47 at the tip of the rotating shaft 35 in the inner female threaded body 45 to sandwich the inner side plate 48. Reference numeral 49 denotes a cylindrical body that is integrally fixed to the outside of the shaft cylinder 43 via radial support plates 51, 51, 51, and the shaft is inserted into internally expanding notch grooves 53, 53, 53 provided in the axial direction on the outer periphery. Three blade plates 55, 5 that can be freely inserted and removed from the direction
7 and 59 are arranged radially. A bolt 61 is screwed into the outer female threaded body 45 and fixes the outer side plate 63. The side plates 48, 63 are the wing plates 55,
It holds both ends of 57 and 59. Note that the female thread of the inner female threaded body 45 may be replaced with an inner diameter hole, and the threaded portion 47 may be extended and screwed into the outer female threaded body 45 and fixed with a nut. Wing plate 55,5
As shown in FIGS. 3 to 5, the outer edge portions 65, 67, and 69 of 7 and 59 are provided at different positions in the axial direction, respectively. Reference numeral 71 denotes a guide cover fixed to the engaging portion 19 by screws 73, which covers the rear, sides, and bottom of the snow removing blade 41, and covers the snow removing blade 41.
1 to guide the scattered snow diagonally upward. 75 is a snow shovel provided at the lower end of the guide cover 71.

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,
The snow removing blades 41, 41 on both sides are rotated and driven in the direction of arrow A in FIG. 2 via the rotating shaft 35. When the operator grasps the grips 11 and 13 with both hands and pushes the snow removal unit 1 forward with the snow shovel 75 in contact with the ground, the snow on the ground is scraped and guided by the rotating snow removal blades 41 on both sides. It is guided by the cover 71 and is scattered and released diagonally forward and upward.

Even with heavy snow such as frozen snow or compacted snow, the blades 55,5
Since the outer edges 65, 67, and 69 of the rollers 7 and 59 are provided at different positions in the axial direction, the length of each outer edge is short, and therefore the snow can be shoveled powerfully. be.

In addition, in FIG. 6, three blade plates 79, 79, 79 whose outer edge portions 77 are in the same axial position are provided in a shape to engage with the groove portion 53, and the blade plates 55, 79 described above are
This was installed as a replacement for 57 and 59, and it is efficient in raking soft snow with a large surface area.

In addition, when attaching and detaching the vanes 45, 47, and 49, remove the bolts 61 and the side plates 63, and the vanes 4
5, 47, and 49 can be easily inserted and removed in the axial direction. Further, if the guide cover 71 is made to be able to be detached by dividing the side portions of the snow removal blades 41, it will be easier to insert and remove the blades.

[Effect of idea]

Since the present invention has the configuration as described in the claims, it can easily crush even heavy snow such as frozen snow and compacted snow, and can also prevent snow from getting stuck and improve snow removal performance. It is possible. Furthermore, if the blades of the present invention are installed so that they can be replaced with blades whose outer edges have the same axial position, the blades can be easily replaced in both heavy and light snow. This makes it possible to perform snow removal work easily and efficiently.

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.
