Introduction to the structure of concrete mixer trucks
, Mixing drum
The mixing drum is the main component of the concrete truck, which is mainly composed of the cylinder, sealing tube, blades and mixing blades. The funnel-shaped sealed tube can ensure smooth feeding, and the curved blades contribute to the discharging performance of low-slump concrete. There are holes on the blades, which can reduce the adhesion of concrete on them and help improve the performance of ready-mixed concrete. the quality of. The entire mixing cylinder is installed above the bracket, and is supported by two supporting wheels at the front. There is a manhole on the mixing cylinder for easy maintenance.
, Transmission system
The transmission system adopts the power extraction method of the original vehicle engine, that is, the power is extracted from the chassis engine, and the power is transmitted to the variable piston hydraulic pump through the universal coupling. The high pressure of the hydraulic pump The oil drives the quantitative plunger motor, and the hydraulic motor transmits the power to the reducer and drives the mixing drum to rotate forward or reverse to realize feed agitation, mixing and discharging. The output flange of the reducer can be within the range of + Deflection can compensate for the displacement of the mixing drum axis, ensuring that the driving of the mixing drum is not affected by distortion and deformation during driving.
Hydraulic system
The hydraulic system is mainly composed of hydraulic pumps, hydraulic motors, oil filters, oil tanks, high-pressure oil pipes, low-pressure oil pipes, oil return pipes and filters. The hydraulic pump is equipped with a manual servo adjustment handle, which can adjust the flow and direction of the hydraulic oil to control the steering and speed of the mixing drum. The forward and reverse rotation of the mixing drum can be adjusted steplessly.
, Control system
According to customer needs, it is divided into rod system control or flexible shaft control.
The lever system controls are distributed on both sides of the rear of the vehicle. Both sides of the rear are equipped with lever system control systems. When the control handle is pulled, the lever system can drive the adjustment handle of the hydraulic pump and the engine throttle to adjust the flow and direction of the hydraulic oil. , thereby controlling the feeding and discharging soft shafts of the mixing drum, which are distributed on the left side of the rear of the vehicle, making it simple and flexible, and easy to operate.
