2. Function overview

18 tons dry type road sweeper adopts the work device arrangement of "central sweeping brush vacuum cover and spiral slide plate adjustment combined mechanism + central pure suction type overall suction nozzle". The center-mounted pure suction integral suction nozzle picks up the garbage, the unique sweeping vacuum cover negative pressure collects the sweeping dust, and the fan conveys the airflow to completely filter the road surface. It has the characteristics of combined suction and sweeping, three-stage dust removal, and all-weather operation in rain or shine. It has many patents such as "road sweeper cleaning device", "road sweeper dust removal device", "dry and wet dual-purpose road sweeper" , At the leading level of domestic and foreign technology, leading the development of the industry, is the pioneer of dry road sweepers in my country.

3. Scope of application
It is suitable for mechanized cleaning and cleaning operations on highways, ring roads, urban arterial roads, airports, docks, etc., because the truck can perform cleaning operations without sprinkling water to remove dust, especially suitable for water shortage areas and winter cleaning operations in northern my country .

1. Chassis

Chassis. It adopts the Tianjin DFH1180EX8 Type 2 vehicle chassis modification produced by Dongfeng Motor Co., Ltd., which has strong power and strong carrying capacity. This chassis is currently the domestically advanced technology and reliable quality of the national six emission commercial vehicle chassis.
Engine. It adopts Dongfeng Cummins D6.7NS6B230 diesel engine with a rated power of 169kW and a rated speed of 2300r/min, and its emissions reach the National Sixth Standard.

2. Sub-engine installation
Sub-engine. It adopts Dongfeng Cummins QSB5.9-C160-30 diesel engine with a rated power of 119kW and a rated speed of 2200r/min, and its emissions reach the National III standard.

3. Nozzle

It adopts a full-floating double-pipe pure suction integral suction nozzle to walk on four wheels, and is connected with the chassis with multiple degrees of freedom, so that the suction nozzle can be automatically leveled with the ground conditions, stabilizes the suction air gap between the suction nozzle and the ground, and has a strong cleaning ability. The overall design of the nozzle structure is simple, reliable, maintainable and maneuverable. The center-mounted pure suction type overall nozzle has a length of more than 2000mm, a large coverage area, high cleanliness of the working road, no blowback and dust, which not only avoids the impact of the vehicle’s passing due to the small approach angle and exit angle, but also avoids The rear-mounted suction nozzle forms a gray mark due to the rolling of vehicle wheels, which is very suitable for cleaning operations on highways and urban roads.

4. Cleaning device

It adopts a unique sweeping plate combined with a sweeping vacuum cover and a spiral slide plate adjustment mechanism. The injection-molded sheet-type sweeping brush is convenient and quick to replace. The vacuum cover and the sweeping brush can be raised and lowered synchronously, and can realize independent compensation adjustment after the sweeping brush wear when the vacuum cover maintains a stable working state, realizing the cover body The technical combination of envelope sweeping, ring-shaped tuyere suction sweeping dust, sliding vertical compensation sweeping brush wear, cover and sweeping brush synchronized retracting and other technical combinations, not only solves the problem of sweeping dust, but also solves the road surface with different working conditions At the same time, it solves the technical bottleneck that the pure suction road sweeper cannot clean the curb rubbish in the industry, and fills the gap in the industry.

The unilateral sweeping disc adopts a single oil cylinder to lift and retract, which has good anti-collision performance, simple and reliable, and low maintenance and use cost.

5. Trash can

The trash bin adopts a single-layer corrugated structure, which is corrosion resistant, large in volume, without framework, and has a long continuous cleaning operation time. It is especially suitable for occasions where the expressway has a long continuous operation time. Because there is no skeleton, it is convenient to dump garbage and easy to clean.

The electric controller is adopted to automatically control the compressed air pulse blowing and cleaning, and the humanized design is easy to operate. There are three automatic dust removal modes: standard dust removal, forced dust removal, and external air source maintenance dust removal, which are reliable in work and high in dust removal efficiency.
6. Dust removal system

The three-stage dust removal system adopts gravity dust reduction, inertial collision, and filter cartridge filtration, which has the function of classification and collection. The primary level is pneumatically guided to achieve gravity dust removal in the trash bin; the second level is inertial collision dust removal; the third level is the filter cartridge group pulse automatic control dust removal, which realizes classified dust removal and classified collection according to dust size, high dust removal efficiency, reliable work, and effective Continuous dust removal operation takes a long time.

7. Fan

The special high-efficiency centrifugal fan is installed at the end of the dust removal system. The fan fully filters the air intake and discharge, is environmentally friendly and dust-free, avoids the wear of the fan volute and impeller by the dust in the airflow, and has a long service life. The exhaust outlet of the fan is equipped with a dedicated exhaust muffler, which has a good noise reduction effect.

8. All-weather operating system

Set up the switching damper for the cleaning operation in sunny and rainy days, which can realize the mutual conversion between the dry dust removal operation of the road sweeper in sunny days and the cleaning operation in rainy days. It can work regardless of sunny, rainy or cold winter, realizing all-weather operation.
9. Safety protection system

It has the functions of reversing the automatic suction nozzle, the trash bin support rod and the trash bin lifting interlock protection, as well as various voice safety prompts such as opening the back door of the trash bin, dumping garbage, and operating music.

The trash can lifting cylinder is equipped with a balance valve group, which has the function of preventing falling when the trash can is lifted. At the same time, there is a manual safety brace for easy maintenance. It is equipped with a sensor to prevent the trash can from falling suddenly when the manual strut is operated by mistake.
10. Hydraulic drive control system

Two sets of hydraulic drive control systems are designed. The raising and lowering of the dustbin and the opening and closing of the rear door can be controlled by the main and auxiliary engines individually or simultaneously. When the main engine is controlled by independent power, it is not necessary to start the auxiliary engine to realize the dumping and unloading of the dustbin. The operation is practical and simple, especially when dumping garbage, it can avoid the auxiliary engine starting to drive the fan to blow soot and dust.

11. Job operation mode
The vehicle adopts the control mode of "display screen + controller + CAN bus operation panel". When the job is started and stopped, the auxiliary engine speed control, nozzle lifting, sweeping and retracting and other operation devices are all controlled by one button, which is easy to operate. The operation of the vehicle is realized by 3 operating devices, two of which are in the cab and one is on the operating panel on the right side of the rear of the vehicle.
Display screen. Located at the front right of the driver's seat, it is mainly used to control various cleaning operations of the vehicle. Digital operation screen, the operating system integrates functions such as operation operation, status display, monitoring, alarm, and system management.
Operation box. Located next to the gear in front of the driver's seat, it is mainly used for starting and stopping the auxiliary engine and opening and closing operations of the dust reduction spray.

Operation panel. Located behind the rear wheel on the right side of the vehicle, it is mainly used for unloading, debugging and maintenance of the trash bin.
