Description

[Detailed description of the invention] (Field of industrial application) This invention is used as a snow removal device that improves the functionality of a small snow removal machine for general household use.

(Prior Art) Conventionally used snow removal machines either throw snow with an auger or blower, or remove snow by equipping a tractor or jeep with a push plate (earth removal plate), or use an auger or blower to remove snow. Some proposals have even been made to remove snow by attaching and detaching a soil removal plate to the front of the snow removal plate, but in any case, these snow removal ideas are unified, and while using a soil removal plate, it is possible to remove snow by using the soil removal plate. There is no technical idea to use an auger to remove excess snow. In recent years, with the spread of small snow blowers in general households, there has been a demand for a snow removal device that can easily remove snow even when there is a small amount of snowfall or snow with high moisture content such as solid snow. It is.

(Problems to be solved by the invention) In view of the above-mentioned circumstances, the technical problem of this invention is to provide a small snow removal device suitable for general households that has a high operating rate and is efficient in snow removal processing. It is.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, this invention was developed based on technology based on many years of experience and observation in snow countermeasures, and was developed as a snow removal device consisting of a push plate arranged in front of the auger so that it can be raised and lowered. In this case, the height of the back plate of the push plate is the height from the road surface to the vicinity of the auger shaft, and the vertical cross-sectional shape of the back plate is S-shaped.

(Function) According to the above configuration, since the longitudinal cross-sectional shape of the back plate is S-shaped, when snow is removed by pushing with the push plate,
Excessive snow is smoothly introduced into the auger from the upper end of the back plate, so that the auger can remove the snow, and the snow removal resistance above a certain level is not applied to the push plate.
On the other hand, from the standpoint of snow removal work, in addition to the conventional snow removal by pushing and shoveling with an auger, it is possible to remove snow by shoveling and shoveling with an auger.

(Example) To specifically explain this invention with an example,
As shown in FIGS. 1 and 3, the snow removal device a of this invention has a push plate 1 which is disposed in front of an auger so as to be able to rise and fall freely, and a back plate 2 of the push plate 1 has a height from the road surface. The height up to the vicinity of the auger axis 7 is selected, and the shape of the back plate 2 is such that its vertical cross section is S-shaped, as shown in FIG.

As shown in FIG. 2, the back plate 2 constructed in this manner has a claw plate 3 integrated at its lower end, an arm 4 integrated at its left and right sides, and a handle 8 at the front part of the arm 4.
A coil spring 9 is stretched between the middle part of the handle 8 and the middle part of the arm 4 to form a push plate 1.

The push plate 1 is rotatably supported at the rear end of the arm 4 by a bearing plate 6 integral with the casing side plate 5 at a required eccentricity with respect to the auger axis 7.

When removing snow by pushing, the push plate 1 constructed in this way can be used with the top two prongs 12 of the stopper 11 shown in FIG. The auger is held in a fixed position at the front of the auger, scoops up shallow snow on the road surface with the claw plate 3 at the bottom of the back plate 2, pushes it out with the lower curved part of the S-shape, and accumulates it in a certain place. Afterwards, as shown in FIG. 3, flip up the push plate 1 upwards around the support shaft 13 of the bearing plate 6 integrated with the casing side plate 5 of the casing 10, and release the left and right handles 8.
The tip of the auger is engaged with the lower two prongs 14 of the stopper 11 in the same manner as described above, and the auger is driven to throw snow to a fixed location. If there is a lot of snow, you can of course remove the snow directly with the auger, but if there is shallow, solid snow, you can rotate the auger while pressing with the push plate 1, and if too much snow is pushed out, the downward curvature will The snow is guided from the upper part to the upper curved part, smoothly overflows from the upper end of the back plate 2, and falls into the auger, which allows the snow to be thrown to a predetermined location via a chute.

In contrast to conventional snow removal methods, which are too shallow and inefficient to shovel with an auger alone, and which gradually become overloaded and reduce work efficiency by pushing only with a shovel plate, this invention's snow removal device a Since snow can be pushed and removed by the push plate 1 and snow thrown by the auger at the same time, snow can be removed extremely efficiently.

(Effects of the invention) As described above, according to this invention, in addition to the conventional method of simply removing snow with a push plate and throwing snow with an auger, it is possible to simultaneously remove snow with a push plate and throw snow with an auger. It has a high operating rate for general household use, regardless of snowfall amount or snow quality, and has the effect of being able to remove snow extremely efficiently.
