The Concrete Mixer Is A Special Heavy Duty Vehicle
- Oct 20, 2017 -


Concrete mixer with car chassis, mixing cylinder, into the material device, water supply system and hydraulic transmission system and other components. The main function of the mixing cylinder is to store and stir the concrete, installed in the rear half of the car frame, mainly by the cylinder, connecting flange, roller and mixing blades. The external structure of the mixing cylinder is mostly both ends of the cone, Concrete Mixer Truck the middle of the cylinder, its shape resembles the olive. Concrete tanks are made of high-quality wear-resistant steel plate, in order to be able to automatically install, unloading concrete, the inner wall of a special shape of the spiral blade. Used to stir and stir the concrete.

The concrete chassis for concrete mixers requires sufficient load capacity and strong output power. General requirements of the engine to have 230kW (300 horsepower) above the power, loading capacity of 6-7m³ of the concrete mixer to be used 6 × 4 mass of 15t class universal chassis, loading capacity of 8-10m³ need to use double front axle 8 × 4 capacity of 20t level of the chassis, and the load of 10-12m ³ will have to use 6 × 4 tractor plus semi-trailer way. Concrete tank rotation is to rely on hydraulic drive mechanism to ensure that the loading capacity of 6-8m ³ of the concrete mixer is generally used by the car engine through the power output shaft drive hydraulic pump, Concrete Mixer Truck and then use high pressure oil to promote the hydraulic motor drive concrete tank. Loading capacity of 9-12m ³, by the vehicle-assisted diesel engine driven hydraulic pump driven hydraulic motor. In addition, the organization design should be reasonable, easy to operate, concrete tank unloading thoroughly, the use of these problems must also be taken into account. For example, if the discharge is not complete, leaving the concrete in the tank will accumulate more, so that the capacity of the tank to reduce, and clean up very difficult. Concrete tank and into the inlet and outlet wear resistance is better, Concrete Mixer Truck sand and stone is the main component of concrete. They make the concrete tank and into the outlet at work wear serious. Under normal circumstances, the use of low-alloy steel production of concrete storage tank life of 50,000 -8 million cubic meters. The life of the spiral blades in the concrete tank is only 30,000 to 40,000 cubic meters. Domestic concrete tanks are generally made of high strength and low alloy steel, which is 1-2 times more resistant than ordinary A3 steel. Some of the imported concrete storage tank with manganese shed special wear-resistant steel, and easy wear parts inlaid wear-resistant material reinforcement, so its service life than low-alloy steel can be increased by 1 times. It can be seen, the use of different materials, its working life is very different. Concrete Mixer Truck The price should be reasonable, after-sales service is the key, concrete mixer is a special heavy-duty vehicles, keep less, less accessories source, compared with the general General Motors, the dependence on the manufacturers. Therefore, manufacturers can provide convenient and reliable after-sales service, is the selection must be considered an important factor.

Concrete mixer in the process and waiting for the discharge process, in order to avoid the water separation or solidification of concrete, through the power plant to remove the power of the chassis and drive the hydraulic system variable pump to the mechanical energy into hydraulic power can be passed to the quantitative motor, The motor drives the reducer again, and the agitator is driven by the reducer to stir the concrete. (2-4r / min), unloading, Concrete Mixer Truck the tank to reverse rotation (12-14r / min), the concrete was rotating the barrel of the spiral blade, even continuous discharge. The change in the speed of the tank and the direction of rotation are done by the control rod of the variable oil pump - changing the pump speed, displacement and high pressure oil outlet transposition (pump reverse rotation).

The time for transporting concrete by concrete mixers can not exceed the time specified in the mixing station. Transport concrete on the way, the mixing cylinder shall not be a long time to stop, to prevent the phenomenon of segregation of concrete.

Concrete mixer truck finished, should immediately use the car's hose to the water inlet, hopper and out of the chute and other parts of the rinse, the stick in the body around the dirt and residual concrete, and then to the mixing Fill the water within the cylinder 150-200L of water, in the way back to the mixer to slow rotation to clean the inner wall, to avoid residual material slag attached to the cylinder wall and mixing leaves, Concrete Mixer Truck and once again before filling the water to let go. Concrete mixer truck finished, should immediately use the car hose to the water inlet, the hopper and the material chute and other parts of the rinse, the stick in the body around the dirt and residual concrete, and then to the mixing Fill the water within the cylinder 150-200L of water, Concrete Mixer Truck in the way back to the mixer to slow rotation to clean the inner wall, to avoid residual material slag attached to the cylinder wall and mixing leaves, and once again before filling the water to let go.

Concrete mixer to transport concrete, the engine speed in the range of 1000-1400 r / min, so that the engine has the maximum torque, in the transport of concrete, the speed should not exceed 40km / h, Concrete Mixer Truck to ensure the safety of traffic.
