1、Beautiful and practical Carriage Design
Under the premise of meeting the requirementsof the use and strength, it overall employs SUS304 single-layer stainless steelproduction with the advantage of simplicity and practicality and with goodtechnology. Besides, trash integrates water tank so as to increase the volumeof water, and bring mass production and processing. Trash can be set up withinthe anti-overflow alarm device and high pressure spray cleaning device. When itoperates, the anti-overflow alarm device can prevent the sewage from the straw,which can avoid resulting in secondary pollution. Furthermore, after dumpinggarbage, the high pressure spray cleaning device can automatically clean thetank, greatly reducing the operators’ labor intensity.

2、CleaningMechanism with Self-adaptive Control

Ground pressure of sidewashing system employs spring as adjustment mode which could adjust the groundpressure at any time according to the road conditions during work to reduce thewashing wear. In order to reduce the washing wear, ground pressure of sidewashing system employs spring as adjustment mode which could adjust the groundpressure at any time according to the road conditions during work. In order tosolve the problems on sweeper brushes’ obtacles-free, one end of the supportingoil cylinder employs connected shackle to keep oil cylinder floating. When thesweeper brushes encounters obstacles, it has the function of automaticcollision avoidance.

3、HighEfficient Duct System

Duct system is the basis ofpneumatic transmission of sweeper-washer vehicle and it includes suctionnozzles, carriage channels and fans. The total three key parts decide thesuction force, air loss, systematic power and etc. And they are the core partsin the design of sweeper-washer vehicle.
(1)Efficient suctions disc
The vehicle employs a fullfloating nozzle structure with double suction nozzle built-in high pressurespray bar so that the road garbage collection, ground high pressure washing andsewage recovery function can be achieved completely in one-stop opearation.

(2)Efficient centrifugal fan
It employs high pressure centrifugal fan which is selfdevelopedped and its max air volume can reach 10000m³/h. It has bigfull pressure and high efficiency. The fan leaves are made of special steelmaterials and their shapes are not easy to wear.
4、Reliable and effective waterway system
(1)Waterway with low pressure and dust
Equipped with stainlesssteel sprinkler and with a low-pressure fan-shaped surface of the nozzle, thescraper can suppress the dust from the brush. Nozzle is also installed withdust spray pipe and self-made large-diameter nozzle, which can suppress the dustthat comes with picking up the garbage by the scraper.
(2)High pressure waterway
High-pressure pumps areimported from Itay. When the high-pressure pump starts and the work valvesswitch, the pump can automatically unload. With the triple protection of theair cycle, safety valve and relief valve, high-pressure water pump can beeffectively prevented from damage. The rear part of the car is equipped withmechanical automatic winding reel and with 20m high pressure hose, which can beused to clean the body, other equipment and
5、Handy PTO interface

Assistant engine employsJMCS JX493ZG3 / JE493ZG5. The assistant engine drives hydraulic pump directlythrough PTO interface to improve transimission efficiency, reduce trasmissionof supporting housing, save oil consumption, reduce operation cost of users anddecrease the failure rate effectively.

6、PowerTake-off System

Assistant enging ofsweeper-washer vehicle employs automatic clutch output protection device as itsprotective setting to ensure the unloading start and stop of assistant engine.It solve the problem that the power take-off impact is large and it has betterperformance in protection of engine, fan and high pressure water pump.

7、IntelligentControl System

(1)Integrated control mode
Thesweeper-washer vehicle is equipped with advanced intelligent control mode. Whenoperating, it just needs to select the job mode. Then the operation ofstartting and shutting down is automatically controlled by the program. Theoperation mode includes full cleaning operation, left washing operation, rightwashing operation, full sweeping operation, left sweeping operation, rightsweeping operation and pure suction operation mode etc.

(2)Muti-safety protection
Themuti-safety protection includes voice alarm protection, voice avoidancewarning, voice failure alarming, low water level of clean water carriage, highwater level of garbage carriage, low oil level of hydraulic oil carriage, reardoor unopened alarm, safety supporting which is not put down and otherprotective devices. The vehicle has a reverse protection device. That is tosay, the automatic recovery of the work device can be achieved when the vehiclereverses.
(3)Real-time job monitoring
Themonitoring probe with high-definition is set in the right turret and the rearof the trash. Besides, a high-definition LCD display ia also set in the cab. Asa consequence, the screen can be switched to the right and the rear of thetrash position respectively so that the quality of vehicle operations can bemonitored.
A high-pressure water pump beltdetection device is set. When the high-pressure pump belt is removed, itensures the cleaning can be carried on without water can. When thehigh-pressure pump belt can be normally installed, it can alarm, thusprotecting the high-pressure water pump.
8、Safe and reliable hydraulic system
Byadopting the chassis and assistant engine power of the dual-power hydrauliccomponents system, dumping discharge, nozzle lift and sweep lift can beachieved by chassis and vice engine. When the dumping is carried out, it isonly necessary to start the chassis engine, without starting the assistantengine. As a result, the number of revolutions of assistant engine increases.All these not only extend the service life of the assistant engine but alsosave the fuel.
Byusing three-valve independent hydraulic system, the hydraulic system workwithout interference and is easy to maintain.
Byusing plate stack valve procuded by the well-known domestic manufacturers inBeijing Huade, it is reliable and easy to maintain with stable performance.

9、High Wear TechnologySweeping and Washing with Mixed Materials
Throughself-development, the proportion of polypropylene, polyethylene raw materials,inorganic filler and its addictive has been adjusted to design and develop aformula of brushes which is with excellent performance in friction wear. At thesame time, all experimental formula has been tested to develop speical nylonsweeping brush hair for Xugong and its service life has been increased twotimes.
