Machine overview:The use of high-power, water-cooled Cummins QSB6.7-C220 diesel EFI engine, can adapt to large-width and heavy-duty heavy-duty paving needs, increase the area of the tank to ensure that the engine in heavy, high temperature environment normal continuous work;The use of the world's top hydraulic parts suppliers, the German imports Rexroth hydraulic components and their walking reducer, greatly improve product quality, product adaptability, reliability and its life to enhance;Full hydraulic drive - can achieve paving speed, speed, speed, vibration, vibration frequency stepless adjustmentPaving speed constant speed control - to improve the pavement of the flatness, with a set of turning radius function can be achieved smooth curve paving;high-rigidity with vibration, vibration, two-stage telescopic ironing device in the maximum telescopic position also has a large expansion and rigidity, to ensure that the main vice-ironing device paving state consistency, vibration, vibrating frequency stepless adjustable , Especially adapted to the paving of asphalt materials;Scraper conveyor with high wear-resistant chain and hardened chain pin. All parts that are in contact with the paving material are made of imported high wear resistant steel and are easily replaceable.diameter 480mm large spiral fabric leaves, bearing bearing on the paving flow resistance to a minimum, to reduce tMeter for Liquid & Gas he material segregation;two vertical and one horizontal automatic leveling control system, ultrasonic level control, imported Rexroth RC12 microcomputer constant speed control system, imported electronic control components, can achieve automatic and precise control;easy maintenance - the friction parts of different parts of the use of centralized continuous forced pressure lubrication or dispersion of forced pressure lubrication.full flip hood and external cover, easy maintenance of the internal body;professional design of the engine cooling duct and radiator, 24 hours to ensure continuous construction equipment and other extreme requirements;large hopper, wide screed structure, which can effectively improve the quality of paving;minimum paving width of 3 meters, the maximum stretch paving width of 6 meters, machinery widened to 9 meters.3. The main assembly performance characteristics:
ENGINEModel: QSB6.7-C220 (Cummins), high power reserve, high adaptability of the plateau, wide range of applications.Form: 6-cylinder inline pressurized water-cooled diesel engineRated power: 164kW / 2200rpmFuel consumption at full load: 210 g / kW.hDiesel tank capacity: 350LWALKING Using external motor, built-in walking reducer left and right track independent full hydraulic drive; microcomputer control electronic electronic constant speed control; paving speed can be pre-set; according to the selected speed and curve constant speed accurate paving. The drive unit consists of a variable motor and a large-speed planetary reducer. The variable motor is integrated with the planetary gear unit and can be automatically turned and the curve is paved smooth. Work files and travel files are free to switch.Crawler walking deviceThe frame frame adopts bending and optimization design so that the strength and rigidity of the walking device are multiplied, and each side of the track has 11 permanent lubrication rollers, the track grounding area is 3185mm x 320mm. To ensure the smooth and stable walking for high-grade pavement to provide a strong guarantee;
After the special strength and hardness of the process of dealing with the chain track, the use of split rubber track shoe and a larger contact area of the walking track, even in poor conditions of the road, but also to ensure stable and reliable work of the paverSteering Through the steering potentiometer knob to rotate left and right, causing the crawler drive wheel speed changes, to achieve a smooth turn of the paver, steering angle adjustable to more accurately control the paver steering, steering can achieve constant speed smooth steering, steering radius Stepless adjustment, until the original turn.Parking brakeIn the two planetary reducer installed in the hydraulic normally closed brake, can achieve automatic shutdown power, safe and reliable.HoHardware Accessories pperUltra-durable design of large-capacity hopper, hopper floor thickness of 24mm, capacity of 15.5t, hopper with three support, so that the hopper load evenly distributed to adapt to a variety of tonnage truck unloading, from the left and right hydraulic cylinder Put, to ensure the continuity of paving.Push devicePush cylinder with long design, and has a certain swing angle, to achieve the top push the car when the balance of the top thrust.Scraper feeding systemOn both sides of the left and right have a separate hydraulic drive device, by the pump, cycloid motor, planetary reducer and chain drive components, running speed up to 28m / min, through the level device to achieve automatic control.Spiral feeding systemThe left and right sides have independent hydraulic drive device, composed of plunger pump, cycloid motor, reducer and chain drive drive system, the maximum speed can be 80r / min, through the ultrasonic level device to achieve speed proportional automatic control, but also The stepless speed change is achieved by manual operation of the console.
Spiral fabric height According to the requirements of paving operations can be fast hydraulic stepless height adjustment to adapt to different conditions; spiral leaves using high chromium cast iron,Wear resistance, greatly enhance the service life;
The use of double-row rod structure of the spiral baffle plate to improve the stiffness of the spiral baffle plate to ensure the stability of the screw feeding, reducing the screw system when the downtime on the impact of walking host, reducing the spiral system Jitter on the leveling system of interference, greatly improving the pavement smoothness.Central concentration
Automatic lubrication system.The use of imported progressive distributor, according to the design of the interval automatically evenly to the high temperature bearing oil, a good solution to the scraper bearing and spiral lifting bearings artificial lubrication difficulties.Electronic control systemThe core components using Rexroth RC12 controller, the operator can move the direction of the handle to achieve the direction and speed of fine-tuning control; speed by a potentiometer to achieve speed control; steering potentiometer to achieve steering control; and BODEM software real-time fault monitoring, And calibration process parameters and other functions, in order to achieve the walking system of the closed-loop variable speed chain control.Automatic leveling deviceUsing a contact automatic leveling system, with two vertical and one horizontal, by adjusting the leveling device, you can achieve the height of paving pavement adjustment.Ironing systemHydraulic retractable screed with large stiffness of 8 guide rods plus two telescopic cylinder two telescopic structure, the basic width of 3 meters, the maximum telescopic width of up to 6 meters, the mechanical lengthening to 9 meters, stable and reliable, no jitter phenomenon ; The main screed and the extension of the height difference can be adjusted; the use of ratchet wrench to adjust the arched; box frame structure and widened floor, thereby reducing the ironing device on the road unevenness of the sensitivity, Effectively improve the flatness of the paving. Screed the bottom plate with imported high wear-resistant material, a unique stud welding, greatly improving the effective use of wear-resistant substrate thickness, thereby effectively improving the wear-resistant floor life.Vibration SystemVibration mode using eccentric shaft vibration, vibration frequency 0 ~ 50Hz can be adjusted according to the requirements of the road, to achieve the ideal flatness.Vibrating systemVibrating frequency between 0 ~ 25Hz stepless adjustable, vibrator: single vibration, vibrating amplitude of 5.heating equipmentPropane gas heating screed, ignition heating system coupled with self-priming duct, so that screed heating efficiency is higher, more uniform, to ensure the stability of the heating system.OthersLight and can slide around the console, can achieve the paver driver in any location to facilitate the operation.Full of the hood and the outer cover, to ensure that the maintenance process of the paver inside the body within reach, easy maintenance.The porter is easily hydraulically folded during the transportation and over the culverts to avoid the building.Hydraulic oil temperature sensor with automatic shutdown protection device.Ladder can be 90 degrees flip, to achieve maintenance, adjust the spiral sprocket box fast and convenient.
