How does a self-feeding mixer truck mix concrete?

　　The manufacturer of full-automatic self loading mixer is composed of automobile chassis and special equipment for concrete mixing and transportation. A special truck used to transport concrete for construction; Because of its shape, it is often called snail car. The working principle is that the power of the automobile chassis is taken out through the power take-off device, and the variable pump of the hydraulic system is driven to convert the mechanical energy into hydraulic energy and transmit it to the quantitative motor. The motor then drives the reducer, and the reducer drives the mixing device to mix the concrete.

　　1、Drive the mixer truck under the charging hopper of the mixing plant to align the inlet hopper of the truck with the outlet hopper of the mixing plant, so as to prevent the concrete from flowing outside the truck, causing waste and polluting the car body.

　　2、Place the handle of the servo valve of the oil pump at the central position, and the mixing drum is at a standstill

　　3、When the material is loaded to the nominal stirring capacity, operate the handle. When the engine speed is adjusted to 1800r / min, the stirring speed of the mixing drum is 1 ~ 3R / min. after the engine speed is small, lock the handle in the cab and drive the vehicle to the delivery place. The allowable time from the beginning of feeding to the end of unloading is 1.5 hours or 300 revolutions of mixing drum (whichever is shorter).

　　4、When the mixer truck goes uphill with full load, the rotation speed of the mixing drum shall be properly accelerated.

　　5、Before operating the handles on both sides of the rear of the vehicle, the cab operation positioning locking plate shall be loosened to realize the forward and reverse operation of the rear of the mixing drum. Then discharge according to the speed required by the construction site.

　　6、After each unloading, clean the feed hopper, inside and outside of the mixing drum and the discharge chute to prevent the concrete from solidifying on the above parts.

　　The daily maintenance of the full-automatic self feeding mixer is also very important:

　　1、In car maintenance, including maintenance of lubrication system, fuel system, cooling system, braking system, carburetor (fuel nozzle), etc.

　　2、Car body maintenance, including car paint, cushion carpet, bumper, skirt, dashboard, tire, wheel hub, windshield, chassis, etc.

　　3、The brake system of mixer truck is very important for the stability of vehicle. Also check the working condition of the air pump and the wear of the air pump belt frequently, and replace it in time.

　　4、after a certain mileage, change the front and rear tires, so that we can make the best use of the tire and prolong the service life of the tire.

　　5、Pay attention to the maintenance of the wiper. The original factory has designed the cleaning field of vision. Privately lengthening the length of the wiper blade can increase the visible range of the window field of vision, but it will also add the burden of electrical equipment such as heavy rain wiper motor.
