Description

[Detailed Description of the Invention] The present invention relates to a snow removal device that removes snow by scattering it using snow removal blades that are rotated by the drive of an engine.

Conventionally, the gear case installed at the tip of the operating rod has a
In a snow removal device that is equipped with snow removal blades that are pivoted in the horizontal direction and rotated by the drive of an engine, and a guide cover that guides the snow that is scattered by the snow removal blades, this guide cover is not fixed. Since the rotating position of the guide cover could not be adjusted, the position of snow removal and the direction of snow scattering could change depending on the height of the worker, the length of the operating lever, changes in the terrain, etc. I was unable to do any work.

In the present invention, this guide cover is provided to be rotatable around the axis of the snow removal blade, and the guide cover is fixed to the gear case so that its rotational position can be freely adjusted. The purpose is to adjust the rotational position according to changes in the length of the operating rod and the topography, making the work easier.

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

In the figure, 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 fixedly provided on the operating rod 3; 13 is the operating rod 3;
This is a grip provided at the end of the handle 15 that is fixed to the handle. The snow removal section 1 is constructed as follows. That is, 17 is a gear case, and one end thereof is provided with a cylindrical 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. 2
5 is a bevel gear supported by a bearing 27 inside the gear case 17, and 29 is a bevel gear 2.
The engagement body is screwed onto the boss portion 31 of No. 5, and holds the bearing 27 between it and the bevel gear 25 in the axial direction. The engaging body 29 is connected to the square shaft portion 3 at the end of the transmission shaft 7.
3 are removably engaged. A rotating shaft 35 is rotatably supported by bearings 37, 37 horizontally in the gear case 17, and a bevel gear 39 that engages with the bevel gear 25 is fixed thereto. 41, 41 are snow removal blades provided on both sides of the gear case 17, which are fixed by three blade plates 47, 47, 47 between two circular side plates 43, 45 that face each other on the inside and outside, and rotate. The side plate 43 engages with an engaging body 49 that is screwed onto the end of the shaft 35, and the side plate 45 on the opposite side
A guide cover 57 is integrally formed by connecting the snow removal blades 41 and 41 on both sides by bolts 55 through a bearing 51 and a spacer 35, and guides and discharges shoveled snow forward and upward. The rotating shaft 35 is attached to the outer plate of the
It is rotatably supported on a coaxial core. The engaging portion 19 is provided to penetrate the guide cover 57, and the guide cover 57 is fixed to the engaging portion 19 so that its rotational position can be adjusted. The engaging body 49 is provided with three radial engaging portions 59 , 59 , 59 , and is engaged with an engaging hole (not shown) of the same shape provided in the side plate 43 . 61 and 63 are engagement holes provided in the gear case 17, and 65 and 67 are engagement holes 6, respectively.
Bolts 69 and 71 pass through and are fixed in engagement holes provided in the guide cover 57 at positions corresponding to 1 and 63. 73 and 75 are the engagement holes 61 and 6, respectively, when the guide cover 57 is rotated in the direction of arrow A in FIG.
The engagement holes 77 and 79 provided in the gear case 57 at positions corresponding to 3 move the guide cover 57 to a position where the guide cover 57 is further rotated in the direction of arrow A in FIG.
This is an engagement hole provided in the. Reference numeral 81 is a cover that fits on the operating rod 3, 83 is a bracket that projects from the cover 81, and 85 is a connecting plate that engages the bolts 69 and 71 at both ends, and a screw piece 87 is fixedly provided thereon. Reference numeral 89 is a bolt screwed into the screw piece 87 to fix the bracket 83 to the connecting plate 85. 9
Reference numeral 1 denotes a raking guide plate provided in the opening at the bottom of the guide cover 57 for raking snow on the ground.

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 removal blades 41, 41 on both sides are rotated and driven in the direction of arrow B in FIG. 3 via the rotating shaft 35. The operator grasps the grips 11 and 13 with both hands and presses the scraping guide plate 9.
When the snow removal unit 1 is pushed forward with the snow removal unit 1 in contact with the ground, the snow on the ground is scraped up by the rotating snow removal blades 41 on both sides, guided by the guide cover 57, and scattered and discharged diagonally forward and upward. be.

For example, if the worker is short, the operating rod 3 will be lowered and the front edge of the raking guide plate 91 will be in a position away from above the ground surface, so the bolts 69, 71
, and rotate the guide cover 57 in the direction of arrow A in FIG.
When engaged at positions 7 and 79, the scraping guide plate 9
1 can be adjusted so that the leading edge of the ground is properly in contact with the ground surface.

In the above-mentioned embodiment, the rotational position of the guide cover is adjusted in three stages, but the engagement hole may be formed into a long hole so as to be adjustable steplessly.

Since the present invention has the configuration as described in the claims, the rotating position of the guide cover is adjusted according to the height of the worker, the length of the operating lever, and changes in the topography.
The work can be done easily and work efficiency can be improved.

In addition, a guide cover is integrally formed to cover the rear and upper parts of the snow removal blades that are separately provided on both sides, and has a raking guide plate on the lower opening edge. Since it is freely fixed, the structure is simple and the adjustment operation is easy.

In the above-mentioned embodiment, the engine is provided at the end opposite to the operating rod, but the engine may be provided integrally with the snow removal section. Further, the guide cover may be fixed to the gear case indirectly, such as by being adjustably fixed to an operating rod or the like that is fixed to the gear case.

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.
