Concrete
mixer mainly consists of the components of the chassis and upload simply can be
divided into: chassis systems, hydraulic transmission, mixing tank, discharging
systems, cleaning systems, sub-frame, steering system, roller system, feeding
system , the ten components of the circuit system.
1,
chassis systems: The main part of the mixer, the whole function is to transport
concrete mixer from the chassis to achieve.
2,
hydraulic drive system: the engine power by removing the power take off, into
hydraulic energy (displacement and stress), and then the motor output
mechanical energy (speed and torque), provide the impetus for mixing drum
rotates.
3, stirred tank: mixing tube is a key
component of the mixer truck is stored in concrete containers, to prevent
concrete curing, segregation plays a decisive role. Tank internal vane, mainly
from the mixing and guide material effect.
4, the feeding system: mainly by the main
chute, deputy discharge chute, locking lever, etc., from the role of deputy
main discharge chute to extend the length of the slot.
5, the cleaning system: cleaning system
consists of a pressure tank, water gun, water pipes, valves and other
components. Using pressure water supply, the main role is to rinse after
Bahrain feed hopper and a complete wash after mixing tube feeding, discharge
chute to prevent concrete bonding.
6, sub-frame: mixer sub-frame is the main
load-bearing part, almost all of the load job to support it then passed through
the chassis. Subframe also help ease the bumpy road, slow down the formation of
shock loads role. Entire sub-frame from the main beam, front bracket, backstage
support frame components.
7,
the operating system: the operating system by the controller, the linkage
shafts, shaft and connecting rod bodies, mainly to control the speed and
direction of rotation of the mixing tube.
8,
roller system: mixing tank connected to the rear of the sub-frame parts, mainly
from the supporting role of the drum body.
9,
the feed system: the composition of the feed hopper with the holder, into the
hopper impact wear due to greater abrasion resistance material requirements,
mainly from the stent to reduce the force of the impact.
10,
a circuit system: mainly refers to the entire circuit mixer, including the
vehicle's tail lights, side marker lights, showing porch lamp, cooling fan
motor.
Mixer
mixing function principle: power take the power of the engine driven hydraulic
pump drive shaft through a small hydraulic motor to rotate through reducer
drive mixing drum rotates. During the transportation of concrete, the need to
maintain the stirred tank 1-3 revolutions per minute at a low speed, in order
to ensure homogeneous concrete, while preventing the concrete segregation,
called agitation (stirring commonly known).
Truck
loading function principle: when the concrete mixer in the mixing tank loading
speed faster, speed of 6-10 rpm, concrete mixing tube through the charging
system into the catheter from the tube, and in the helical blade guide, the
flow of agitation in the lower part of the cylinder. Note: the direction of
rotation during transport of the tank when the charging should be consistent,
or in the concrete during transport will be discharged.
Truck unloading function principle: when
unloading truck engine will power through the PTO, hydraulic pumps, gear and
other transmission to the mixing tank, drive tanks rotation speed of 3-14 rev /
min; concrete blade By pushing the role of a spiral motion to move the cylinder
port direction, after unloading bucket truck unloading. At this point the
direction of rotation of the feed tank and in the opposite direction.
Mixer
cleaning function principle: air reservoir tank to the braking system
pressurized water through a pressurized mixing tank cleaning system, loading
port, concrete mixer drum roller,
unloading systems.
