A concrete mixer truck comprises a special truck chassis, a mixing tank, a material inlet and outlet device, a water supply system, and a hydraulic system. The role of the mixing tank is to stir and mix concrete. The mixing tank mainly consists of a tank body, connecting flange, raceway, and Stirring blade composition. The shape of the mixing tank is mostly pear-shaped, also called a snail cart. The material of the mixing tank is generally a high-strength steel plate.
The truck is equipped with a cylindrical mixing drum to carry the mixed concrete. During the transportation process, the mixing drum will always be kept rotating to ensure that the concrete carried will not solidify. In order to automatically load and unload concrete, shaped spiral blades are welded to the inner wall of the mixing tank. When the mixing tank rotates forward, the concrete in the tank will not solidify quickly because it is continuously stirred. When it rotates reversely, the concrete will automatically flow from the shoe. The material port is discharged.
Concrete mixer truck operation precautions
1) Each time the mixing materials are added, the amount must not exceed the specified value, and the hopper can only be lifted and loaded after the materials are discharged from the mixing drum.
2) Actual combat shall not be delegated at will.
3) During the feeding process, water must be added in time to reduce mixing time and dust flying.
4) When the hopper is lifted, no one is allowed to stay under the hopper. The empty hopper should be lowered slowly to increase the service life of the machine parts.
5) Operation by non-operators is strictly prohibited.
How to use a concrete mixer truck
1) The mixer should be installed on solid and flat ground to prevent it from tipping due to ground subsidence.
2) Before use, all systems of the machine should be inspected according to the procedures of cleaning, tightening, lubrication, adjustment, and anti-corrosion, and make them meet the requirements; any potential accidents must be eliminated in time.
3) Electrically driven mixers and power distribution equipment should be equipped with appropriate fuses and grounding devices to ensure the safety of the electrical system.
4) When the mixer is running, do not let sand and gravel fall into the running part of the machine, otherwise, the parts may be easily stuck and damaged.
5) After the feed hopper is raised, no one is allowed to pass or stay under the hopper.
6) The machine cannot be stopped without reason before discharging materials, nor can it be started after adding materials. The input amount cannot exceed the specified capacity.
7) After the mixing work, the mixer must be cleaned in time to prevent concrete from caking. When cleaning, prevent electrical equipment from getting wet. Cleaning must be done after the power is turned off to prevent electric shock.
Maintenance after use of a concrete mixer truck
1) Before stopping the machine, a certain amount of stones and water should be placed and stirred for three to five minutes and then released. Repeat this process several times to remove the accumulation in the cylinder. After each shift, the accumulation in the cylinder should be cleared.
2) Clean the dust and concrete adhered to the whole machine.
3) Place the hopper in the transportation position and hang the safety hook.
4) Cut off the power supply.
5) Add the necessary lubricating oil to each lubrication point as appropriate.
