Abstract

The utility model belongs to a wind blowing device for purposes such as snow removal, dust removal, desiccation, etc. The utility model comprises a power machine arranged in a housing. At least two wind wheels are arranged on an output shaft, and the front part of the wind wheel is provided with a taper wind guide cylinder. The utility model adopts the structure of multistage wind wheels, wind force of a wind outlet reaches a higher degree, the utility model can be made in a portable way, with small-area operation carried out. A group of wind blowers can also be arranged on the head of a trolley or an automobile, operations such as snow removal, etc., are carried out to large-area places, and the utility model solves the problems of large volume, bulkiness, high fabrication cost, etc., existing in the existing snow removal machinery.

Description

Large thrust blower

The utility model is a kind of hair-dryer, particularly a kind ofly is used to remove the snow, the Large thrust blower of function such as dedusting and protection against the tide.

Northern area snowfall in winter is more, and therefore snow removing is a bigger engineering.The snow removing that particularly resembles places such as runway will accomplish in time, thoroughly, will employ great amount of manpower, expend a large amount of time.Aerodrome snow removing now all is to adopt bulldozer to push away, and this equipment volume is big and heavy, cost is very high.

The purpose of this utility model provides a kind of Large thrust blower, and it can overcome existing shortcoming in the prior art, and volume is little, cost is low, and efficient.

The purpose of this utility model is achieved in that it comprises the engine that is installed in the casing, it is characterized in that two wind wheels are housed on the output shaft at least, and the taper ventilating duct is equipped with in the wind wheel front portion.

Above-mentioned engine comprises motor and gasoline engine.

For increasing work efficiency, can be shaped on rifling at the inwall of ventilating duct.

The utility model adopts the structure of multistage wind wheel, makes the wind-force of air outlet reach higher degree, so can be as efficient snow removing, dedusting, also can be used for drying and fire extinguishing etc., owing to the utility model compact conformation, reasonable, so volume is little, in light weight, and cost of production is lower in addition.The utility model can make portable, carries out the small size operation, also one group of hair-dryer can be installed in the head of trolley or automobile, to operations such as large-area place and speedway etc. remove the snow.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
