Technical Field

The invention relates to the field of pipeline transportation and the field of treatment of wind and sand environments, in particular to a wind and sand dredger.

Background

With the increase of population, the range of human activities is also expanding continuously, but when people reform the wasteland, the transformation of human is brought with difficulty to places that some people and machinery are difficult to directly contact, such as burning fire pit, open-air natural coal pile, steep mine pit, swamp, quicksand and the like. The traditional transformation mode is that an excavator is used for transporting soil and sand from one place to another place, but for a place where machinery and human beings cannot directly contact with dangerous places, people can blow the sand to a needed place by means of wind power.

The sand-blown filling machine described by the invention utilizes the Venturi effect principle, and high-speed flowing wind meets narrowed pipelines, and the wind force can be gathered and accelerated, so that sand-blown filling can be used for filling roadbeds and reforming hollow places, or extinguishing fire; people can fill and level up the depression without direct contact, and other operations can be carried out in the place of filling after the landfill is finished, so that the use of manpower and the risk brought by manpower construction are reduced.

The venturi effect, principle, is that when wind blows over an obstacle, the air pressure is relatively low near the port above the lee side of the obstacle, creating an adsorption effect and causing a flow of air. The gas flow is reduced from thick to thin to accelerate the gas flow velocity, so that the gas forms a vacuum area at the rear side of the venturi outlet, and when the vacuum area is close to the workpiece, a certain adsorption effect is generated on the workpiece.
