The use of of concrete mixer truck

First, the basic configuration of the concrete mixer
Concrete mixer mainly by the undercarriage, the mixing tube, drive (the drive), hydraulic drive system, water system, installed (into) materials and material unloading system, discharge chute, suspension platform, operating system and protective equipment.
Tilt angle: 15 degrees
Rotational speed (r / min): 0 ~ 14
Concrete Slump (mm): 70-260
Direction of rotation: Clockwise feed, counterclockwise discharge
Barrel material: high carbon steel 5-6mm
Blade: 4.5mm double helical blades
Discharge capacity: Cone sink 5cm / h
Unloading the remaining amount: <1% cone sink 5cm / h

Second, the concrete mixer System Description
Mixing drum: the mixing tube used in the form of the model is a more general structural form, the mixing tube using the pear-shaped structure, the cleaning water and transportation as needed adding the mixing water, by the head into the mixing tube feed opening injection barrel.
Transmission: The mixing tube-driven approach to the engine as the power source, the rear end of the engine PTO PTO, passing through the shaft to the variable piston pump, the quantitative plunger motor oil, was stirred by the reducer drive drum rotation.
Mixing tube and out of the feeding system (loading and unloading mechanism): It is an important means an auxiliary mixing tube work.
Operating system: the whole mixer control components, has opened a "work-shaped" grooves on the control panel, the joystick space; and the open slot on the rear half of the limited spaces hole for fixing the position of the joystick. The control system through the left rear of the car two joysticks to control the mixing tube, reverse and speed, so to finish out of the material and the stirring action.
Water supply system: concrete mixer of the water supply system is mainly used to clean the mixing device. The model of the water supply system has two types, one is the centrifugal pump water supply system; one is the pressure tank water supply system, an option available to users.
Third, the concrete mixer Caution
1, the hydraulic system pressure should comply with the instructions for use, and shall not be adjusted. Hydraulic oil and fuel oil should comply with the original requirements.
2, before loading concrete mixers, you should drain the remaining water and mix barrel debris. During transport to keep the rotation, to prevent concrete segregation. Beforeconcrete mixer truck access to the site and unloading, should make full mixing drum to 14-18 rev / min rotation for 1-2 minutes, then invert discharge. Before reversing, should be parked mixing tube does not turn.
3, the ambient temperature is above +25 degrees Celsius, from the loading, transport, the discharge duration shall be more than 60 minutes, the ambient temperature is below +25 degrees Celsius, the above time shall not exceed 90 minutes.
4, winter construction, should earnestly: before starting the check for icing; work when the barrel and mix carefully exclude residual water supply system, turn off the pump switch, the control lever in the "stop" position.
