Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a snow removal machine capable of compressing and removing accumulated snow.

(B) Prior Art Conventionally, various types of snow removers have been developed, one of which is described in Japanese Patent Application Laid-open No. 58-65808.

This involves installing a snow removal auger in front of the driving vehicle, and installing a snow blower behind the auger.
A distribution chute is provided above the snow removal blower, the tip of the distribution chute is connected to a compressor consisting of a hydraulic cylinder and a compression cylinder, and the compressor is further provided with a compressed snow mass discharge device.

Moreover, with this configuration, snow can be discharged in the form of clumps.

(c) Problems to be solved by the invention However, this snow blower had the following problems.

Since the distribution chute and the compressor are constructed as separate units, the device becomes larger, the manufacturing cost increases, and maintenance becomes complicated.

Since the distribution chute is a long vertical cylinder, the snow blower must have a large capacity, which also increases manufacturing costs.

The released compacted snowpack must be transported outside using a truck and cannot be disposed of on the spot.

An object of the present invention is to provide a snow removal machine that can solve the above problems.

(d) Means for solving the problem The present invention includes installing a snow collecting auger driven by a prime mover in front of the snow blower body, and installing a blower blowing the collected snow upwards behind the auger. The base end of a snow compression cylinder whose tip extends in the width direction of one side of the snow blower body is connected to the upper part of the blower, and a rotating shaft to which a snow discharge spiral is fixed is rotated within the snow compression cylinder. The present invention relates to a snow blower which is movably disposed and is characterized in that the rotation locus of the blower is divided into front and back directions from the axis of the rotating shaft and eccentric by an amount of eccentricity.

(E) Function The snow collecting auger and the blowing blower rotate as the prime mover is driven, and the snow collected by the auger is sucked into the blowing blower, then fed into the snow compression cylinder, where it is compressed. Afterwards, snowflakes continuously fall from the opening at the tip of the snow compression tube onto the road surface as snowflakes.

In such discharge work, since the rotation locus of the blower is eccentric from the axis of the rotating shaft, the snow that is raked up from the blower to the snow compaction tube is
Since the snow is discharged along the blades of the snow transfer spiral without colliding with the rotating shaft, the discharge efficiency is further increased.

(f) Effects Since the snow blower is essentially composed of a blower, a snow collection auger, and a compression cylinder, the structure is extremely simple, the manufacturing cost is low, and maintenance is easy.

Since the rotation locus of the blower blower is eccentric from the axis of the rotating shaft, the snow that is raked up from the blower to the snow compression tube is discharged along the blades of the snow transfer spiral without colliding with the rotating shaft. Therefore, the discharge efficiency can be improved.

Furthermore, since snow is less likely to interfere with the rotating shaft within the snow compression cylinder, it is possible to reduce drive horsepower.

(G) Examples The present invention will be explained in detail below based on examples shown in the attached drawings.

In FIGS. 1 to 3, 10 is a snow blower main body that is equipped with a drive source and an operation section of the snow blower, and the snow blower main body 10 has left and right crawler bodies 11 on both sides,

This accumulation auger 15 is attached to the snow removal machine main body 10.
Right and left spirals 17 and 18 having opposite spiral directions are fixed to both sides of the auger mounting shaft 16 extending in a direction perpendicular to the direction of movement of the auger, and both ends thereof are connected to the running frame of the snow blower main body 10. It is constructed by rotatably supporting the auger support side plates 19, 19 provided therein.

With this configuration, when the snow collecting auger 15 rotates, snow is collected in the center of the auger 15.

Further, blowing blowers 20 (two blowers in this embodiment) are provided behind the snow collecting auger 15, and the front center portion of the blowing blowers 20 communicates with the center portion of the snow collecting auger 15. It is connected.

With this configuration, the blowing blower 20 can suck up the snow collected in the center of the snow collecting auger 15 and then blow it upward.

Furthermore, a snow compression tube 21 is horizontally suspended above the blower 20, and the base end of the snow compression tube 21 is communicatively connected to the upper opening of the blower 20. The tip extends toward the width direction of one side of the snow remover main body 10.

The sheet can be discharged to the outside in the width direction of the sheet.

The snow compression tube 21 also includes a cylindrical body 22 whose diameter gradually decreases from the base end to the tip, and a rotating shaft 23 rotatably disposed inside the cylindrical body 22.
and a snow discharge spiral 24 fixed to the rotating shaft 23.

With this configuration, the snow discharge spiral 24
As it rotates, snow is fed toward the tip, but
Since the diameter of the cylindrical body 22 gradually decreases toward its tip, the feeding resistance gradually increases.
As a result, the snow will be compressed and the snowpack will be expelled from the tip.

Further, in the above configuration, as is clear from FIG. 1, the rotation locus of the blower 20 is eccentric from the axis a of the rotating shaft 23 in the snow compression tube 22 by an eccentric amount e in the front-rear direction.

With this configuration, the snow raked up from the blower 20 to the snow compression tube 21 is discharged along the blades of the snow discharge spiral 24 without colliding with the rotating shaft 23, thereby improving the discharge efficiency. be able to. Further, since snow is less likely to interfere with the rotating shaft 23 in the snow compression tube 21, it is possible to reduce the driving horsepower.

Further, the tip of the snow compression tube 21 can be configured to be expandable and retractable. That is, as shown in FIG. 3, by attaching the telescopic hose 25 to the distal end of the cylindrical body 22 so as to be movable in the axial direction, only the opening position of the distal end can be freely changed.

With this configuration, when the snow compression tube 21 is in the tip retracted position, the tip opening is located in the front of the crawler body 11, a snow mass is dropped at the same position, and the snow compaction is crushed and compressed by the crawler body 11, and the road is cleared. It can make walking easier.

On the other hand, at the advanced position, the tip opening of the snow compression cylinder 21 can be extended to the outside of the crawler body 11, and the snow can be discharged to a transport vehicle and the outside can be transported and disposed of.
