In urban life, there are two types of common sanitation vehicles: garbage trucks and sprinklers. Under normal circumstances, there are two kinds of garbage trucks, which are more widely known as hook-arm garbage trucks and rear compression garbage trucks. Relatively speaking, the compact garbage truck started late in China, and its internal structure is more complex than the hook-arm garbage truck. In this issue, we will focus on the compact garbage truck. Working principle: Compression garbage truck is composed of sealed garbage container, hydraulic system and operating system. The entire vehicle is fully sealed, self-contained, self-dumping, and sewage in the compression process all enter the sewage chamber, which completely solves the secondary pollution problem in the garbage transportation process.
Zoomlion’s compact garbage truck has become the world's leading garbage truck
The operating principle of the compact garbage truck is roughly divided into four phases: The first phase: The scraper swings upwards and is ready for insertion into loose waste. The second stage: The skateboard drives the scraper down and inserts the loose waste in the collection box. The third stage: The scraper swings down to make a circular arc, scraping the trash and allowing it to enter the main compartment. Stage 4: The skateboard moves the scraper up and fills the garbage into the main compartment. This completes the filling cycle.
Zoomlion's compression-type garbage trucks produced by Zoomlion have become global mainstream garbage trucks because of their advantages such as high pressure, good sealing, large load, and easy operation. The use of compressed garbage trucks in China is relatively short, and the first compact garbage truck was independently developed by Sany Group. So far, there have been hundreds of companies producing compressed garbage trucks across the country, and there are compressed garbage truck manufacturers represented by Zhonglian, Beijing Hualin, Fujian Longma, and Aerospace Chenguang.
Zhonglian's garbage trucks generally use Dongfeng's chassis. The dustbin is made of reinforced beams and steel plates welded to form a solid frame structure. The bottom plate is concave, the sides and the top surface are arcuate curved surfaces, beautiful and not easily deformed; the push shovel is composed of a steel pipe skeleton and a folding panel, which is not only structurally lightweight but also capable of making The garbage is evenly distributed and the unloading is thorough; the filling device is mainly composed of shells of the filler, slide plates, scrapers and other components. Each component adopts a beam plate or box structure with good stress, and has a firm structure and light weight. The car body is seamless, without skeleton welding, the appearance is beautiful, and the overall anti-corrosion treatment is required.
In the hydraulic system that lifts the filler, a one-way balancing valve is provided. The valve not only ensures a smooth drop of the filling device, but also blocks the direct connection between the lifting cylinder and the hydraulic hose. Even if the oil tube bursts, the filling device will not drop suddenly and cause a serious accident. Increased use of security.
At the same time, Zoomlion's compact garbage truck adopts PLC integrated control imported from Japan. The logic circuit ensures that all operating instructions are executed in order to reduce the occurrence of faults; the emergency brake button can make the garbage compaction mechanism in any state or Stop at any position to ensure the safety of operators and equipment. The job control box is installed in the cab and rear respectively. The operation control box in the cab can control pushing and unloading and select the operation mode (such as automatic or manual). The rear job control box controls the press filling mechanism and the turnover mechanism. The operation is very easy to use. Especially in landfills, operators can complete discharging and sewage discharge without getting off the train.
It can be seen from China Zoom's compact garbage truck that the compact garbage truck in China has made great progress in recent years. However, compared with foreign advanced compressed garbage trucks, there are still some deficiencies in operational noise, sealability, loading quality, and mechanization. Classification processing is the direction of HEIL is the United States manufacturer of garbage trucks, mainly producing front loading and unloading, rear loading and unloading, side loading and unloading garbage trucks.
The main feature of HEIL compressed garbage is divided into two independent loading hoppers, which are divided into recyclable garbage and non-recyclable garbage loading hoppers. At present, there is no device for such classification processing in China. In some large cities, such as Beijing and Shanghai, the most common way to deal with garbage classification is to use different garbage trucks to load recyclables and non-recyclables. From this point of view, although China's garbage trucks are synchronized with foreign countries in terms of appearance, weight, and electrical control, they are still quite inadequate in terms of waste sorting and automation.
Control Arm:
The Control Arm respectively through a ball joint or bushing to wheel and body elastically connected together. The control arm connect the car body and wheel together with Ball Joint or rubber bushing,so it need to be sufficient on the stiffness, strength and service life.
Usually,the metal is manufactured via Aluminium Die Casting or forging.
The car is divided into a front arm swing arm and the lower arm, the swing arm is suspension guide and support, the deformation of the wheel positioning, reduce vehicle stability; and the lower arm of the main role is to support the body, Shock Absorber and buffer driving vibration of reducer. Under the suspension arm can play a supporting role well, with shock absorbers and springs of tacit agreement can constitute a set of excellent suspension system (assembly).
Different category:
1. Lateral stabilizer bar link
During the suspension installation, stable rod one end of the connecting rod through the Rubber Bushing and the stabilizer bar links, the other end is connected by rubber bushings or ball hinge with the control arm or the shock absorber tube, stabilizer bar connecting rod used in selecting a symmetry, which improve the operating stability.
2. Tie rod
In the suspension installation, tie rod end of the rubber bushing is connected with the frame or body, the rubber bushing is connected with the hub. Another section of the transverse rod multi link suspension control arm should be used for such multi vehicle and steering system, mainly subjected to lateral loads, while the guide wheel movement.
3. Vertical pull rod
Mostly applied for vertical rod suspension to transfer drag, traction and braking force.
4. Single control arm
This kind of automobile control arm is mostly used in multi link suspension, and two single control arms can be used to transfer the lateral and longitudinal loads from the wheel.
5. The fork arm (V)
The control arm of automobile used under the arm of the double wishbone suspension on the arm of wheat Jefferson suspension fork structure, the main arm of the lateral load transfer.
6. Triangle arm
The control arm of automobile used under the arm of the front suspension Jefferson wheat suspension, used to transfer the horizontal and vertical load, the relative motion control of the wheel and body.
