Description

Description: TECHNICAL FIELD The present invention relates to a snow treatment device for removing snow from the side of a road.

(Prior art and its problems) When it is time for snowfall to become root in snowy countries, the edges of the ordinary roads are covered with snow from the roadway and the snow that secures the passageway to the house. Will be difficult.

That is, most of the snow removal on the sidewalk is not removed except for a part even if the snow removal is performed to secure a roadway.
If it becomes heavy snow, it becomes more difficult to walk, and it becomes impossible to use the sidewalk. Therefore, it is necessary to walk on a dangerous road.

In addition, as a method of treating snow piled up on the side of a roadway or a sidewalk, it is also thrown into a river or the sea by truck transportation, but since the snow is large and the volume is large, truck transportation is also difficult. It is work. Also, when the temperature drops below zero, the adhesion between snow and snow becomes difficult, and it is difficult to adhere snow to each other outdoors to form snow (solidify). Will be difficult.

(Object of the Invention) In view of the conventional circumstances as described above, the present invention aims to facilitate the solidification of snow even in cold regions to reduce the bulk of the snow and to make the handling convenient.

(Structure of the Invention) The technical means taken by the present invention to achieve the above object is to provide a hopper on the circumferential surface of a cylindrical body to form an inlet for snow-removed snow. A pumping means for pumping the injected snow to the outlet side of the cylindrical body is provided, and a vacuum deaeration section for communicating with vacuum equipment such as a vacuum blower or a vacuum pump is provided around the cylindrical body in front of the pumping means. ,
Further, it is characterized in that the outlet of the cylindrical body is narrow.

The hopper provided on the cylindrical body may be provided with a connection gutter which communicates with the snow discharge port of the snow remover.

Further, the pumping means provided in the cylindrical body may be of a screw type or a diaphragm type, and the power source thereof may be the power of the snow blower, or a dedicated power source may be attached separately.

The air in the snow is degassed by a vacuum blower or a vacuum device such as a pump, and the outlet of the cylinder that is compressed and solidified and discharged is narrowed down, or a compression member is attached to the outlet to apply elastic pressure. Any method such as adjusting the degree of compression may be used.

(Operation) According to the above configuration, the snow thrown into the cylinder is pressed and moved forward by the pump by the pumping means, and the vacuum deaeration unit provided in the middle of the cylinder in the longitudinal direction operates the vacuum equipment. The air in the snow is removed. As a result, the volume of snow in the cylinder is reduced, compressed, and solidified into a block shape by the narrow mouth of the outlet or the elastic force and discharged. Then, the above-mentioned compression and solidification are continuously carried out, and a block shape is obtained by cutting at a predetermined length at the outlet.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a cylindrical body, and a hopper 2 communicating with the inside is fixed to a peripheral surface of one side of the cylindrical body to form an input port 3 and A communication gutter 4 that is in communication with a snow discharge port of a snow blower (not shown) is detachably attached to the upper opening. The connecting gutter 4 is a bellows tube so that the connecting portion with the hopper 2 can be pivotally rotated so that it can be connected to and used with various snow blowers, and that it can be expanded and contracted in the vertical and length directions. Has been formed.

A screw 5a that constitutes the pumping means 5 is mounted from the mounting portion of the hopper 2 in the cylindrical body 1 toward the front, and the shaft 5b of the screw 5a is attached to the side portion of the cylindrical body 1 to hold the metal 6 and the thrust bearing 7. A pulley 9 is fixed to the outside of the bearing case 8 through the end of the bearing case 8 and is connected to a dedicated power source or a power source of the snow blower with a belt or the like so that the screw 5a rotates. The number of screws 5a attached to the shaft 5b is not limited to one, but a plurality of screws may be used. The vacuum degassing section 10 provided in the middle of the length direction of the cylindrical body 1 is a cylinder located inside the outer cylinder 11 with an outer cylinder 11 fixed concentrically outside the cylindrical body 1 at predetermined intervals. A large number of intake ports 12 penetrating inside and outside are formed on the peripheral wall of the body 1, and a connection hose 14 for connecting to a vacuum blower or a pump (not shown) is connected to the intake port 13 of the outer cylinder 11. Further, a drain plug 15 is provided on the lower peripheral wall of the outer cylinder 11 so that inspection after use can be performed.

The outlet 16 of the cylindrical body 1 has a narrow mouth for compressing and solidifying deaerated snow. Note that the outlet 16 is not limited to a structure in which the outlet is narrowed to a narrow mouth.
It is also possible to compress and solidify the snow that is pushed out to. In the figure, 17 is a mounting leg.

Next, the operation of the above-described processing device will be described. When the screw 5a of the pressure feeding means is driven and rotated by a dedicated power source or a power source of the snow remover, and snow is thrown into the cylindrical body 1 from the hopper 2, the snow is screwed. The air in the snow is removed by the action of a vacuum blower or a pump connected to the outer cylinder 11 at the vacuum degassing section 10 on the way to the outlet 16 side of the cylindrical body 1 by the rotation of 5a, which is sequentially sent to the outlet 16 side. Then, the volume is reduced and the material is extruded to the outlet 16. Then, since the outlet 16 is narrowed and has a narrow mouth, the snow which is sequentially fed under pressure is compressed, solidified, and pushed out. The snow that is solidified and pushed out becomes a block shape by cutting it at an arbitrary length at the exit, and it becomes possible to easily stack it on the side of a sidewalk or the like.

In addition, this device is installed in a snow removing snow blower, and by connecting a communication gutter to the snow discharging port of the snow remover, it is possible to reduce the bulk without throwing the removed snow to other places or pushing it out. It can be solidified and discharged.

As mentioned above, if the snow volume becomes smaller, the snow pressure on the residents will be greatly reduced even if they are piled up on the sidewalk.
In addition, even when it is loaded on a truck and transported to a dumping place, there is an advantage that the weight to be transported at one time can be increased as compared with the conventional state during snow removal.

(Effect of the Invention) Since the snowfall treatment device of the present invention is designed to deaerate, compress, and solidify the air in the snow in a vacuum state during the pressure-feeding movement in the cylinder, the temperature is low and the snowfall is low. Compared with the conventional process of removing snow to the side of the road and stacking it with mountains, the adherence of comrades is weak and solidification is not possible. Can be done. As a result, especially for school roads with snow piled up on the sidewalk, it is difficult for school children to walk, and it is dangerous to pass the snowplow equipped with this device through the center of the snowy mountain sidewalk. By processing the snow cover, a new flat snow road is created on the sidewalk without removing other snow and safe walking is possible. Also, by reducing the bulk and solidifying it, even when it is loaded on a truck and transported to the dumping place, the weight that can be carried by one unit can be significantly increased compared to conventional truck transportation, and it is very efficient. Is.

Further, since the device has a simple structure in which only the pumping means and the vacuum degassing part are provided in the cylindrical body, the snow removal by connecting the supply (input) of the snow to the cylindrical body with the snow discharge port of the snow remover. However, the snow can be compressed and solidified to reduce the bulk, and the work can be continuously performed.

Therefore, a highly practical processing device can be provided.
