Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a snow removal machine, and more particularly to a small snow removal machine that can easily scrape off snowdrops accumulated on an am.

Conventionally, there was no suitable method for removing lightning from roofs in areas with heavy snowfall, other than climbing onto the roof and scraping off the lightning with a shovel, which was extremely dangerous and labor intensive. Moreover, in some cases, it was necessary to do it for several days, and it was extremely hard work, especially when it was done on a large roof. However, although large snow removal machines that run on mines, roads, and railroads have been proposed in the prior art, no one with a small and simple structure that can scrape off snow accumulated on roofs has yet to be proposed. Ta.

The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to remove lightning piled up on a roof etc. by using a pair of spiral rotating members whose screw directions are opposite to each other.

The goal is to improve safety. Another object of the present invention is to rotate the spiral rotating member so that the displacement of its rotating shaft and the outer peripheral portion of the contact in the horizontal direction is always upward, so that the spiral rotating member bites into the snow and sinks; The purpose is to prevent such floating. Another objective is to connect the rotating shaft of the helical rotating member to a drive mechanism so that it can swing vertically, so that it can be adapted to any slope of the roof. The purpose of the present invention is to make it possible to remove snow from rooftops, roads, and even concave ditches. Another purpose is to rotate the helical rotating member in the opposite direction.
That is, by providing a propulsion wheel that rotates in the forward direction, it is possible to overcome the reverse rotation of the spiral rotating member and move the snow removal machine forward by power. It is also an object of the present invention to provide a snow removal machine that is small in size, has a simple structure, and is lightweight and low cost.

It is freely supported. The first drive shaft 18 has a sprocket 22 at the right end, a pinion 23 at the left end, and a sprocket 24 at the intermediate portion held by the vertical frame 2b, each of which restricts axial movement. It has become stuck. A chain 27 is wound and buttoned between the sprocket 22 and a sprocket 26 fixed to the motor shaft 5a of the motor 5, and the diameter of the sprocket 22 is set larger than the diameter of the sprocket 26. Therefore, the first drive shaft 18 is driven at a reduced speed with respect to the rotation of the motor 5 via the sprockets 26,22.

The second drive shaft 19 is connected to one set of horizontal frames 2a of the seven-frame member 2.

Chains 40 and 41 are wound between sprockets 32 and 35 and between sprockets 24 and 36, respectively, and since the diameter of sprocket 36 is set larger than the diameter of sprocket 240, the third drive shaft 2o is adapted to be driven at a reduced speed with respect to the rotation of the first drive shaft 18 via a tin rocket 24°36.

An elastic member 43 having an uneven surface is fixed to the outer circumferential surface of the propulsion wheel 7, and the outer circumferential surface of the elastic member protrudes downward from the bottom of the skid member 3.

As shown in FIGS. 1 and 2, the rotating member 8 is attached to both ends of the third drive shaft 20 and is swingable in all directions via the rotating shaft 8a due to the universal hinge 45. is connected to. In FIG. 2, the rotating member 8R on the right side has a spiral body 8b with left-handed threads in multiple directions, and the rotating member 8L on the left side has a spiral body 8b with right-handed threads in multiple directions.
is formed. Further, the left and right rotating members 8L and 8B are restricted from swinging in the front-rear direction by a support member 46 that has one end fitted into the intermediate portion of these members and the other end fitted into the horizontal frame 2a, and is restricted from swinging only in the vertical direction. Supported for free movement.

Also, the motor 5, the rotating member 8, the tip member 4, the skid member 3
It is constructed so that it can be appropriately assembled and disassembled with respect to each parts manufacturer and frame member 2 such as.

When the switch 16 is turned on and the motor 5 rotates, the sprocket 26 rotates clockwise as shown in FIG. That is, the snow removal machine 1 is rotated in the forward direction, and the snow removal machine 1 is pushed forward by the power of the motor 5 through the elastic member 43, while the front end 4a of the front end member 4 sweeps the lightning from side to side.

Further, the rotating members 8L and 8R are in contact with the rotating shaft 8a in the horizontal direction via the sprockets 22, 24 and 36.
It is configured to be given a rotational movement in a clockwise or partial backward direction so that the displacement of C is always upward, and by this rotational movement, the snow is sequentially transferred left and right outward to remove the snow.

The present invention is constructed as described above, and its operation will be explained below. As shown in FIG. 6, in order to remove the snow 51 accumulated on the roof 50, the w51 is first scraped off with a shovel or the like only at the area where the snow removal machine 1 is to be placed. Next, the motor 5, the rotating member 8, the tip member 4, the skid member 3, the frame member 2, and other parts are carried in a disassembled state onto the roof 50 and assembled. When the assembly is completed, insert the glove 14 into the t-source and turn on the switch 16.

Then, the propulsion wheel 7 rotates counterclockwise as shown in FIGS. 4 and 6 and moves through the elastic member 43! The machine 1 moves 1151 in the direction of arrow A by the tip 4a of the tip member 4.
While shoveling the snow from side to side, the snow 5 is removed by the skiing member 3.
Slide on the top surface of 1 and then play forward. The snow 51 shoveled in this way is sequentially moved to the rotating member s1. ．． It is sent to the base of sB. At the same time, clockwise as shown in Figure 5,
The rotating shaft 8a and the horizontal opposing contact outer peripheral part 8c
A rotating member 8L that rotates in a direction in which the displacement is always upward.
The snow 51 is sequentially transferred to the left and right tips by the respective spiral bodies 8b of 8R, and falls from the roof 5o. In this case [as shown in Fig. 5, the rotating member 8 rotates so that the opposed contact outer peripheral portion 8C is always displaced upward, so the frictional force with the sleeve 51 acts downward, and the rotating shaft 8a receive,
The rotating members 8L and 8B act on the snow 51 so as to sink into the snow 51, and can powerfully transport the lightning 51.

On the other hand, as shown in FIG. 6, the propulsion wheel 7 is strongly rotated counterclockwise, that is, in the forward direction by the power of the motor 5, so that the rotating member 8 is overcome by the force that attempts to move the snow removal machine 1 backward. Operator 5 was unable to move the snow removal machine forward.
2 only needs to grasp the handle 1o to determine the direction of travel, making the operation easy and safe.

In addition, even if the rotating member 8 is advanced to the end of the roof 50 in the advancing direction, it is safe due to the weight distribution of the snow removal machine 1, so that the snow 51 can be completely scraped off. Furthermore, by providing various lengths of the rotating member 8, roofs of different sizes can be accommodated.

Since the rotating member 8 is swingable in the vertical direction, the snow removal machine 1 of the present invention can be adapted to any slope of the roof 50, and can be used for removing snow from flat surfaces such as rooftops and roads, and even from concave surfaces. It has a wide range of uses as it can also be used to remove snow from left and right upwards.

Further, the rotation speed of the rotating member 8 is suitably about 20 rpm or less, and the propulsion wheel 70 rotation speed is suitably about 1100 rpm or less. Further, each part such as the spiral body 8b of the rotating member 8, the frame member 2, and the skid member 3 can be made of FhP (fiber reinforced resin), and the total weight of the snow removal machine 1 is 100 kg.
g or less.

In the above embodiment, the motor 5 is used as an example of the prime mover, but an engine may also be used. Correspondingly, the grip 11 of the handle 10 is used as a throttle and torque adjusting section to rotate the engine. It may be configured to change the number of rotations. Additionally, the chain may be another positive hooking member, such as a toothed belt, a clip belt, etc. Accordingly, the sprocket should be a toothed rotating member in the form of a gear that is compatible with these hooking members. However, it is not limited to chains and sprockets.

Furthermore, the round part movement mechanism 6 may be constructed of other power transmission mechanisms, such as spur gears and bevel gears.

It is also possible to install a suitable brake device so that the snow removal machine 1 can be stopped immediately.

Also, for nighttime work, lighting lights can be installed in appropriate locations. Furthermore, the snow removal machine 1 can be configured to move backward by operating the switch 16 in the reverse direction to rotate the shimotor 5 in the reverse direction.

Since the present invention is constructed and operates as described above, the lightning that piled up on the Jl base is caused by rotating a pair of spiral rotating members whose screw directions are opposite to each other using a prime mover such as an electric motor or an engine. By doing so, it can be scraped off easily and in a short time, making it easier to remove lightning from roofs in areas with heavy snowfall, and improving safety. In addition, since the spiral rotating member is rotated so that the displacement of the outer periphery of the rotating shaft and the horizontally opposing contact is always upward, the spiral rotating member will be hit by lightning and sink. It is possible to prevent floating snow and to remove snow by powerfully and continuously moving it from side to side.

In addition, the rotating shaft of the spiral rotating member is connected to the drive mechanism so that it can swing vertically, so it can be adapted to any slope of ms, and can be used on flat rooftops, roads, and even concave grooves. It can also remove snow, and its uses are extremely wide. In addition, since a propulsion wheel is provided that rotates in the opposite direction to the spiral rotating member, that is, in the forward direction, the snow removal machine can be moved forward by power by overcoming the rotation of the spiral rotating member in the opposite direction.As a result, the operator The effort involved is greatly reduced, and safety is extremely high. Furthermore, since it is easy to assemble and disassemble, the snow removal machine can be easily transported, for example, to be lifted up and down from the roof. Furthermore, the snow removal machine of the present invention is small in size and has a simple structure, so it can be provided in a lightweight and low cost manner.
