Road surface blowing and blowing machine

　　Road surface sweeping is an important work of daily maintenance of highway, usually using special sweeping vehicles.

　　At present, the widely used sweeper adopts the principle of suction sweeping, the car is equipped with a secondary engine and induced draft fan, the use of secondary pressure will be sucked up the garbage and dust, through the air filtration system to collect the dust collection compartment.

　　The advantage of this suction sweeper is that the effect is good, can meet most of the working conditions of the operational requirements. The disadvantage is that the operating speed is slow, high power, high fuel consumption, high price, maintenance costs are not expensive. Large sweeper operating speed per hour is generally in the 2-5 kilometers or so, the hourly fuel consumption of up to 80-100 liters, its air filter to be often dust, the cost of replacing one is as high as seven or eight thousand or even tens of thousands of dollars.

　　Around 2020, some enterprises launched a pure sweeping type models, won the favor of many users. Its principle is to sweep the brush collected by the mechanical structure of the garbage transmitted to the silo, without the deputy engine, induced draft fan and air filtration system, the structure is greatly simplified, the acquisition cost is greatly reduced, energy-saving effect is obvious. In terms of cleanliness, this vehicle is slightly inferior to the suction sweeping type. There is little progress in terms of operating speed, and the kilometer cost is still high.

　　In 2018, Yantai Equation Machinery Technology Co., Ltd. designed a road surface blowing machine, pioneering a new mode of road surface sweeping, which is rapidly popularized in the field of highway sweeping.

　　This blowing machine acts as a light truck carrier, is powered by a four-cylinder diesel engine, and drives a high-pressure fan to produce high-speed airflow to realize blowing through the belt drive. The equipment is also equipped with water mist dust suppression device, the use of full remote control operation, the driver does not have to get off, through the remote control can be realized by the engine start and stop, the wind pipe put, water mist switch and other operations, for the highway operating environment is very friendly.

　　The price of the blowing machine is only about 1/10 of the sweeper, the fuel consumption of 100 kilometers is only about 8 liters, and the operation speed is up to 30 kilometers/hour or more, so the economic benefits are greatly improved.

　　The disadvantage of belt drive is that it needs to be adjusted and replaced frequently. 2021 Yantai Equation Machinery has launched a direct-mounted blowing machine, the special fan is directly mounted on the flywheel of the diesel engine, which simplifies the whole transmission structure, the volume is small, and the weight is reduced to 600 kilograms, and it can be carried by a pickup truck.

　　Since it is common for highway maintenance units to use pickup trucks for road inspections, it is possible to carry out inspections and sweepings at the same time, thus saving a lot of maintenance costs.
