Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a snow removal machine capable of compacting and removing 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 remover that can solve the above problems.

(d) Means for solving the problems The present invention provides a snow removing auger that is rotatably mounted in front of the snow blower body and is driven by a prime mover.
A blower for blowing collected snow upwards is installed behind the auger, and a snow compression cylinder is horizontally mounted on top of the blower.The base end of the snow compression cylinder is connected to the blower for communication, and its tip is used to remove snow. This snow blower is characterized in that it extends in the width direction on one side of the machine body and has a lid attached to its tip that can be opened and closed in conjunction with the snow compression strength in the snow compression cylinder.

Further, the present invention provides an air vent/snow removal chute which has a net for preventing snow removal connected to the upper part of the base end of the snow compression tube, and a net for preventing snow release at the opening at the lower end of the chute. It is characterized by

Furthermore, the present invention is characterized by a structure in which a crawler is attached to the running section of the snow blower main body, and the tip of the snow compression tube extends above the crawler.

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

In addition, the snow discharged upward from the snow blower mixes air, but the air escapes to the outside through the air vent and snow blowing chute protruding from the top of the base of the snow compression tube, making the snow more compact. It can be done closely.

In addition, by keeping the lid at the tip of the snow compression tube closed and removing the snow prevention net installed at the base end of the air vent/snow removal chute, snow can be removed from the air through the chute. can be discharged.

Furthermore, the snowpack can also be dropped in front of the crawler of the snow blower main body. In this case, the snowpack can be crushed and compressed by the crawler, making it easier to walk on the road.

(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 air in the snow fed from the snow blower can escape to the outside at the base of the snow compaction tube, the compaction density of the snow can be increased.

By using a chute protruding from the upper part of the base end of the snow compression tube for snow removal, snow can also be discharged to the outside in a diffused state as in the conventional case.

Snow masses can be dropped in front of the crawler of the snow blower body and crushed and compressed by the crawler, making it easier to walk on the road.

(g) Examples The present invention will be described 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,

Such a snow collecting auger 15 has left and right spirals 17 and 18 whose spiral directions are opposite to each other fixed to both sides of an auger mounting shaft 16 extending in a direction perpendicular to the direction of movement of the snow blower main body. It is constructed by having both ends rotatably supported by auger support side plates 19, 19 connected to the running frame of the snow blower main body 10.

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

Further, a blowing blower 20 is provided behind the snow collecting auger 15.
0 has its front central portion connected in communication with the central portion of the snow collecting auger 15.

With this configuration, after the blowing section 20 sucks up the snow collected in the center of the snow collection auger 15,
It can be blown upwards.

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.

With this configuration, the snow fed from the blower 20 into the snow compression tube 21 is transferred to the snow removal machine main body 1.
0 can be discharged to the outside in the width direction.

and an opening/closing operation mechanism 27 for opening 5.

With this configuration, the snow discharge spiral 24
As it rotates, snow is fed toward the tip, but
Since the tip of the cylindrical body 22 is normally closed, the feeding resistance gradually increases, and as a result, the snow is compressed within the snow compression tube 22. Thereafter, when the compression force (density of compaction) becomes larger than the spring force of the spring 26 and the lid 25 is about to open slightly, the opening/closing operation mechanism 27 is operated and the lid 25 is moved to the third position.
As shown in the figure, the snowpack is completely opened and falls onto the road surface using the inner surface of the lid 25 forming an inclined surface as a guide surface.

After that, operate the opening/closing operation mechanism 27 to open the lid 2 again.
5 to the original closed position, and in the same way close the snow compression tube 21.

It is also possible to have a structure in which the required lid opening/closing means is automatically opened.

Further, the opening position of the tip of the snow compressor 21 is preferably set in front of the crawlers 11 and 12, so that the snow mass can fall in front of the crawlers, and the crawler can crush and compress the snow.
It can be compressed to make it easier to walk on the road.

Further, in this embodiment, the snow compression tube 21 is equipped with an air vent/snow removal chute 28 that communicates with the snow compression tube 21 at the upper part of the base end thereof. Removable net 28
A is installed.

With this configuration, the snow blower 20
Even if the snow discharged upwardly contains air, the air can be released to the outside through the air vent/snow removal chute 28, and the snow compression effect in the snow compression tube 21 can be improved. .

In addition, by keeping the lid 25 provided at the tip of the snow compression tube 21 closed and removing the net 28a provided at the base end of the air vent/snow removal chute 28, snow can be removed through the chute 28. It can also be discharged to the outside.
