Drum Mixers and Mixer Trucks

When I was a kid I used to love trucks and construction equipment. I had a truck movie that would show all different kinds of cranes, mixer trucks, roller trucks and backhoes. I think there was some sort of construction genie that would explain what all the different trucks did. My favorite machine appeared at the end of the movie. It was a mammoth machine that paved highways. It would crawl along at an incredibly small pace and leave a paved highway behind it. Workers would be running around the machine making sure everything was running smoothly while more workers used long brooms to smooth out the fresh cement. I always wanted to learn more about the machine when I watched that movie but now I know it’s pretty much just a cement mixer and roller in one machine.

Children seem to be the least interested in concrete mixer drum roller compared to the other construction toys. The rotating drum mixer just isn’t as fun to play with when compared to crane arms and big powerful dump trucks. However, cement mixers don’t always come in truck form. There is a smaller mixer that can be attached to a back of a car. I guess the mixer truck and the smaller mixer can mix other things other than concrete but concrete is the most common thing to mix in these.

The mixers blend water and some form of aggregate such as pea gravel or sand to make the concrete. Both mixers can be rented for personal use if someone wanted to touch up their driveway or make a pool. I always wanted to write my name in drying concrete, but never got the chance. I was fascinated with the idea of having written in something that will last decades. Sometimes I see the occasional foot print in sidewalks and I always get a kick out of that. However, it must be a pain for the poor person who made the sidewalk.

Mixer of literacy

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.

Troubleshooting concrete mixer

1, mixing console can not start? Check: whether to start the air compressor and compressed air pressure is normal; overhaul with a key on the host and host protection switch emergency stop switch is turned on; operating table emergency stop switch is turned on; mixing console air switch is turned on; host start and stop signals are normal.

2, after the mixer starts normally, press the start button on the operating table inclined belt, inclined belt does not move? Check: Belt emergency stop switch is turned on; belt air switch is turned on; transmission with start, stop signal is turned on; washing machine button is pressed.

3, in the automated production process, the aggregate weighing is completed, no discharge, the system stops running? Check: to be put in place to close the hopper switch is not sensitive to; aggregate weighing whether to have a discharge signal meter output; whether the belt starts; fine aggregate, said feed door is not fully closed position.

4, batching station stone pneumatic feed material not open the door card, check: batching station pneumatic doors and doors with large gaps small gap doors, large gaps door stone tablets of the gap is greater than the general gap, and thus will not appear card material. A small gap in the door of their gap generally 5-10mm, when the stones below 10mm card into the gap, it is difficult to pneumatic door stuck. But when the dosing station period of time, the discharge port aggregate wear, when the gap is worn to 20-30mm when larger stones into the gap at this time, the door opening process, the gravel is very easy to get stuck, so that the door can not pneumatic turn on.
