With the development of society, mechanization instead of manual operations has gradually become a trend. In particular, the road maintenance and sanitation industries have many roads and areas, and the road traffic volume is also relatively large. If the manual cleaning is not only labor and financial damage, the safety of workers cannot be guaranteed in the face of passing vehicles. Therefore, mechanization becomes so urgent. Required. At present, there are two kinds of special vehicles used for road surface cleaning and maintenance. Scrubbers and sweepers have sweeping functions and are easily confused. But in fact, there is a difference. The first choice can clearly understand the difference between the two. The sweeper has the functions of washing and sweeping, while the sweeper has only the sweeping function. The main structure of the sweeper consists of the vehicle chassis, secondary engine, carriage, hydraulic valve group, sweeping drive motor, hydraulic system filter, electronic control system, vortex pump, sweeping device, suction fan, middle sweeper, and rear suction cup. , stainless steel bins and tanks, diversion tanks and large area filter, television monitors, warning devices. Widely used, it can be used as a sweeping vehicle to clean the road surface, and it can also be used as a high-pressure flushing truck to wash the road surface. It can also be used in combination to achieve a combination of sweeping and washing operations to meet the needs of users. demand. The performance is also very special. The cleaning vehicle combines the functions of a sweeper and a high-pressure cleaner. It also has three functions: sweeping, high-pressure cleaning, garbage collection, and sewage collection. Anti-overflow devices and high-cleaning devices are installed in the garbage cans. The anti-overfill alarm device can prevent sewage from overflowing the suction pipe and cause secondary pollution. The high-pressure spray cleaning device can automatically clean the sewage tank after dumping the garbage, greatly reducing the risk. The labor intensity of the operator. The structure of the sweeping vehicle includes a chassis, a secondary engine system, a blower device, a suction nozzle device, a front scrubbing device, a clean water tank, a sewage waste container, and the like. Its function is relatively single, only with the cleaning function, according to the operating mode classification, can be roughly divided into eight types, namely push (support) type sweeping vehicles, self-style sweeping vehicles, pure sweeping sweeping vehicles, suction sweeping type Road sweeper, pure suction sweeper (multi-function full suction sweeper), dry sweeper (vacuum cleaner), wet sweeper, full suction sweeper. The above is the difference between the functional and structural parts, and the biggest difference is that the auxiliary engine for the sweeping vehicle is the Dongfeng Cummins 140-horsepower auxiliary engine, while the sweeping vehicle is generally equipped with the Jiangxi Isuzu 57kw secondary engine. It can be said that the sweeper can replace the sweeper, but the sweeper cannot completely replace the sweeper's function. According to the current trend, the sweeper is likely to replace the sweeper.
