Structural Principle of Concrete Mixer Truck

 

The concrete mixer truck is composed of a truck chassis and a special device for concrete mixing and transportation.

The chassis of the concrete mixer truck mostly adopts the second-class general chassis provided by the chassis manufacturer. Its special mechanism mainly includes power take-off, front and rear brackets of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc.

The working principle is that the power of the chassis is taken out through the power take-off device, and the variable pump of the hydraulic system is driven, and the mechanical energy is converted into hydraulic energy and transmitted to the quantitative motor. The motor then drives the reducer, and the reducer drives the mixing device.

1. Power take-off device

The cement mixer truck adopts the power take-off method of the main truck engine. The function of the power take-off device is to take out the engine power by operating the power take-off switch, and drive the mixing drum through the hydraulic system. Rotate in the opposite direction to cut off the power connection to the engine after the end of the work.

2. Hydraulic system

The engine power taken out by the power take-off is converted into hydraulic energy (displacement and pressure), and then outputted by the motor as mechanical energy (speed and torque) to provide power for the rotation of the mixing drum.

3. The speed reducer decelerates the output speed of the motor in the hydraulic system and transmits it to the mixing drum.


4. Control mechanism

(1) Control the rotation direction of the mixing drum so that it rotates in the forward direction during feeding and transportation, and rotates in the reverse direction when discharging.

(2) Control the rotational speed of the mixing drum.

5. Stirring device

The stirring device is mainly composed of a stirring drum and its auxiliary supporting parts. The mixing drum is a loading container for concrete. When rotating, the concrete moves along the spiral direction of the blade, and is mixed and stirred during the continuous lifting and turning process. During the feeding and transportation process, the mixing drum rotates forward, and the concrete moves inward along the blades. When discharging, the mixing drum reverses, and the concrete is discharged outward along the blades. The blade is the main component in the mixing device, and damage or severe wear will cause uneven mixing of concrete. In addition, if the angle of the blades is not properly designed, the concrete will segregate.

6. Cleaning system

The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used to mix dry materials during transportation. The cleaning system also cools the hydraulic system. https://www.clvehicles.com/

Introduction of Compactor Garbage Truck

  The   compactor garbage truck   is composed of a sealed garbage hopper, a hydraulic system and an operating system. The whole truck is a fully sealed type, and the sewage in the process of self-compression, self-dumping and compression all enters the sewage tank, which completely solves the problem of secondary pollution in the process of garbage transportation. It has the advantages of good performance, convenient operation and safety. Optional rear hanging bucket overturning mechanism or garbage bucket overturning mechanism. The outstanding features of the compactor garbage truck and other garbage trucks: 1. The garbage collection method is simple: change the dirty old appearance of garbage cans on the streets of the city, and prevent secondary pollution. 2. High compression ratio and large loading capacity: the maximum crushing pressure is 12 tons, and the loading capacity is equivalent to two and a half times that of the same ton of uncompressed waste. 3. Operation ...

How to Prevent Hydraulic Oil From Emulsifying On Concrete Mixer Truck?

The main cause of hydraulic oil emulsification on concrete mixer truck s is water in the hydraulic system, which is mixed with water after a long time. The removed hydraulic oil will form an emulsification of the hydraulic oil. We found that water enters the hydraulic system due to the following reasons: a. Working in a humid environment, the moisture in the air condenses due to the alternation of cold and heat, turning into water droplets and falling into the oil; b. The rainwater on the fuel tank seeps into the fuel tank due to the weak sealing of welding and connection parts; c.  Due to the damage of the pumping cylinder seal and the damage of the mixing motor, moisture is brought into the oil; d. Daily maintenance, cleaning, oil change, and maintenance process bring in moisture. To prevent the oil from emulsifying, we must first prevent moisture from entering the hydraulic system. When the car leaves the factory, the welding and connection parts must be manufactured in accord...

The Maintenance of LED Advertising Truck

 The generator is an important part of the LED advertising truck , and it is the power supply system of the whole truck. Except for the fixed-point parking of our advertising vehicles and plugging in an external power cord for playback, our generators are needed for power supply at other times. Therefore, in order to do a good job in advertising, we must pay special attention to the maintenance of our advertising truck generators. So how do we maintain our LED advertising truck generator? First of all, we have to regularly check the generator of our advertising truck, especially the inspection of the generator oil, and change the oil frequently. Take out the oil dipstick 20 minutes after it is not started or shut down, wipe the oil dipstick with a clean rag or paper towel, reinsert it into the oil hole for 10 seconds, and then take it out to ensure that the oil reaches the middle and upper parts of the lower and upper marks on the oil dipstick. Secondly, we need ...
