According to this snow removal tool, the front edge of the snow removal tool body is pushed into the snow while gripping the rear frame portion and sliding on the bottom surface of the snow removal tool body in contact with the snow surface. The snow can be placed inside the snow removal equipment. Can be dumped in the dump. The snow removal tool body is made of a lightweight hard synthetic resin to which snow does not adhere and which can easily slide on snow.

[0005]

[Problems to be solved by the invention]

 However, conventional snow removal equipment is designed to be used on snow, and is moved by dragging the bottom surface of the snow removal equipment.When used in places with little snowfall, such as in urban areas, asphalt and other There is a problem in that the snowplow itself wears out early due to contact with the ground and cannot withstand use. In addition, even when placed on snow, if the installation surface is slightly inclined, there is a problem that the snow removal tool body easily slides to the side along the inclination, and for the same reason, the There is also a problem that even when the snow removal tool body is moved by sliding, it is often not possible to move as desired due to the tendency to slide along an inclined snow surface. Also, when the snow removal tool is pulled, the snow removal implement body rises rearward, so that there is a problem that, depending on the inclination, the snow piled up easily comes into the snow removal implement body, easily crosses the front edge, slides out, and easily falls off.

[0006] Therefore, the first problem to be solved by the present invention is that, in addition to being excellent in durability, the snow removal implement slides along the slope inadvertently irrespective of the slope of the snow surface in contact therewith. It is another object of the present invention to obtain a snow removal tool that can improve workability when moving the vehicle. A second problem to be solved by the present invention is to obtain a snow removal tool that can be more easily handled in solving the first problem.

[0011]

[Embodiment of the invention]

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The hand-plowed snow removal tool A shown in FIGS. 1 to 4 is formed to include a snow removal tool body 1, a frame 2, and a pair of wheels 3.

The snow removal tool main body 1 has a concave shape with an open upper surface, and is formed to be gradually shallower toward a piercing front edge 4 that is a front edge extending in the width direction thereof, and has a relatively rear end portion. It is lifted at a steep angle and is gradually formed shallower. Therefore, snow can be accumulated in the snow removal tool main body 1.

The plunging front edge 4 is a portion that becomes the head when plunging into the snow when the snow is put in the snow removing tool main body 1. The front edge 4 is preferably covered with a front edge cover 4a made of a thin metal plate as shown in FIG. When the cover 4a is provided, it is excellent in that the leading edge 4 can be protected to prevent breakage of the leading edge 4, but it is not essential in the present invention and can be omitted.

As a material constituting the snow removal tool main body 1 other than the front edge cover 4a, a hard synthetic resin can be used in addition to a stainless steel plate, an iron plate, a lightweight aluminum alloy plate and the like. According to this embodiment in which the snow removal equipment main body 1 is formed of a hard synthetic resin, the snow removal equipment A as a whole can be made lightweight, which is not only advantageous in handling, but also makes it extremely difficult for snow to adhere to the snow removal equipment main body 1. It is excellent in that snow can be detached from the snow removal equipment body 1 very easily when the snow is thrown away from the body 1 to a snow dump. Opening edges except the leading edge 4 of the plunging, that is, both side edges 1a and the rear edge 1b have a groove structure opened downward as shown in a cross section as represented in FIG.

The frame 2 is formed of a metal pipe or the like, and has a front frame portion 5 and a rear frame portion 6 connected to the front frame portion. The front frame portion 5 is housed and arranged inside the both side edges 1a and connected to the edges 1a via bolts and nuts, and the like. The front frame portion 5 is welded and stopped over the frame portions 5a. A bridge frame portion 5b housed inside the rear edge 1b and connected to the edge 1b via bolts and nuts. Although the bridge frame portion 5b may be omitted in the present invention, the structure having the bridge frame portion 5b is excellent in that the strength of the frame 2 and, consequently, the strength of the snow removing body A can be further increased.

The rear frame portion 6 is provided integrally and continuously from the rear end of the side frame portion 5b, is bent in a U-shape, and projects obliquely upward to the rear of the snow removal tool main body 1. The rear frame portion 6 is attached to the upper end bridge portion 6a parallel to the bridge frame portion 5b (see the two-dot chain line in FIG. 1) so that it can be used as a handle when pushing and pulling the entire snow removing tool A. Has become.

The pair of wheels 3 are individually provided on both sides of the rear part of the snow removal tool main body 1. That is, as shown in FIG. 3 and the like, wheel supports 7 each made of a metal plate or the like are welded downward at the rear of the side frame portion 5a, and the wheels 3 are rotatably attached to these lower ends. Have been. These wheels 3 have a width that is as narrow as the diameter of the pipe forming the frame 2. The adoption of the wheel 3 having such a narrow width is advantageous in that the wheel 3 can be easily rotated even when the amount of snow is large. These wheels 3 are provided at a position where the lower end of the wheel 3 contacts the installation surface B when the snow removal tool A is placed on a flat place. When the bottom surface 1c is made substantially parallel to the installation surface B and is set at a height position (see FIG. 2) projecting downward from the bottom surface 1c and in contact with the installation surface B, the abrasion of the snow removal equipment main body 1 can be further reduced. Excellent in point.

The snow removal tool A having the above configuration is used by grasping and pushing and pulling the upper end bridge portion 6a. That is, when loading snow, the snow removal implement A is pushed forward with the front edge 4 of the snow removal implement main body 1 as a head, and the front end 4 is pushed into the snow. In this case, the operation is performed while slightly lifting the rear side of the snow removal tool main body 1, so that the pair of wheels 3 move away from the snow surface or the like, and hinder the forward movement of the snow removal tool A. The snow plunger body 1 is pushed into the snow with the front edge 4 facing obliquely downward while sliding the bottom surface 1c of the snow removing tool body 1 against the snow, and the snow is piled in the snow removing tool body 1. Can be.

Next, the upper end bridge portion 6a is pushed down. Thereby, at least the thrust front edge 4 side of the snow removal tool main body 1 can be inclined obliquely upward so that the front edge 4 of the snow removal tool is raised with the pair of wheels 3 as pivot points. Can be kept away from Thereafter, by pulling the upper bridge portion b, the entire snow removal tool A can be pulled while rotating the wheel 3.

The snow that has been loaded to an appropriate suitable snow dump such as a roadway by such a pulling operation is lifted by raising the upper bridge portion 6a and raising the entire snow removing tool A forward with the plunging front edge 4 as a fulcrum, thereby removing the snow. It can be slid out of the tool body 1 and discarded on a roadway or the like. Then, after that, the bottom surface 1c of the snow removal tool main body 1 is pulled again by the wheels 3 in a floating state, moved to the next snow loading location, and used again for the above loading work.

As described above, the snow can be loaded and transported by one hand-pushed snow removing tool A. In snow removal where the amount of snowfall is relatively small in an urban area, it is necessary to move the snow removing tool A on a pavement surface exposed by snow, such as when going to and from a snow dump. . In this case, as described above, the snow removal implement main body 1 can be lifted off the ground by the wheels 3 and moved without dragging the bottom surface of the snow remover main body 1 to the ground. Therefore, abrasion of the snow removal tool main body 1 is prevented, and durability can be improved.

In addition, since the rotation of the wheel 3 is used in such a movement, the resistance is small and the labor is small as compared with the case where the ground is dragged. Furthermore, the direction of movement can be enhanced by the wheels 3 when moving, so that when moving on the snow surface, even if the snow surface is slightly inclined, the entire snow removal tool A is inclined. It is possible to make it easier to move as you want by minimizing hindrance to moving in the direction you want to slide along. Moreover, in particular, when the snow removal tool A is pulled, the plunging front edge 4 of the snow removal tool body 1 can be raised higher with the wheel 3 as a fulcrum, as described above. It is easy to prevent the snow from falling over the leading edge 4 of the plunge, and it is not necessary to reload the snow. Therefore, for these reasons, it is possible to improve the workability of loading the snow carried out by the above-described procedure.

Further, even when the snow removing tool A is placed on, for example, an inclined snow surface, it is possible to prevent the entire snow removing tool A from slipping sideways due to the resistance of the wheels 3 and to place the snow removing tool A in a stable state. You can do it.

In addition, since a pair of wheels 3 are used and arranged on both sides in the width direction of the rear part of the snow removal tool main body 1, the directionality at the time of movement and the sliding resistance on the inclined snow surface can be further increased. In particular, it is possible to increase the stability at the time of pulling, and it is possible to eliminate the problem that the entire snow removing device A is tilted to the side even when the snow removing device is simply placed. Therefore, handling properties can be particularly improved.

The present invention is not limited to the first embodiment. For example, when the snowplow itself is made of metal, wheels may be attached directly to the rear side surface or via a wheel support. In addition, in the case where one wheel is provided and implemented, a concave groove or a notch is provided in a widthwise central portion of a rear portion of the snow removal tool main body, which is slightly wider than the wheel width, and is opened on a lower surface and a rear surface of the snowplow. The wheels may be mounted rotatably there.

[0026]

[Effect of the invention]

 The present invention is embodied in the form described above and has the following effects. According to the first aspect of the present invention, by providing the wheels, the directionality of the movement in the push-pull operation by grasping the rear frame is enhanced, and the falling of the snow in the snow removing device main body can be prevented. Since the front edge of the snow removal tool can be pulled up with its leading edge raised, the workability of pulling the snow removal tool body to move the loaded snow can be improved. And, since the bottom surface of the snow removal tool main body can be prevented from being worn by contacting with the pavement ground or the like by the above posture when it is pulled, the durability is excellent. Therefore, it is particularly suitable as a snow removal tool used in urban areas and the like. In addition, due to the resistance of the wheels, it is possible to prevent the entire snow removal gear from sliding sideways along the slope, regardless of the slope of the snow surface in contact with the snow removal tool body.

According to the invention according to claim 2 which depends on claim 1, in addition to the effect of the invention according to claim 1, the directional property during movement and the sliding resistance in the lateral direction on an inclined snow surface are reduced. This makes it easier to handle because it can be made larger and more stable when it is pulled, and it also eliminates the problem of the snowplow tipping sideways when it is simply placed. it can.
