1. The rotation of the mixer drum is driven by the hydraulic motor through a special planetary reducer. The output shaft of the planetary reducer can swing at a certain angle to meet the beating of the mixer drum under bad road conditions.
2. Constant power variable piston pump is used in the hydraulic system to reduce the power loss of the engine.
3. The water inlet system can automatically feed water according to the metering setting.
4. Dry material feeding, according to the designed proportion, automatically feeding by shovel arm, boom cylinder and quantitative hopper.
5. A double spiral blade is arranged on the inner wall of the mixing cylinder of the automatic feeding mixing truck, which rotates in a positive direction for feeding and concrete mixing; Under the push of the spiral blade, the concrete is discharged from the discharge port.
6. The traveling system is composed of engine, hydraulic torque converter, front and rear transmission shaft and front and rear axle. The invention adopts a front and rear double axle driving form. The hydraulic torque converter is used to reduce the impact on the engine and prolong the service life of the engine.
There is a big arm beside the cab of the automatic feeding mixer, which is called the loading arm. When the driver operates in the cab, the loading arm can perform a series of landing, shoveling and lifting actions. After a worker sets the material, the driver controls the loading arm to drop the shovel. After the shovel is finished, the driver controls the loading arm to rise and lift the bucket to the mixing tank, Continue to operate and open the back bin opening of the bucket, and the materials in the bucket can accurately enter the mixing tank.
Therefore, the "automatic" feeding of automatic feeding mixer is so simple. Normally, two people can operate smoothly, one is in the cab, and the other is in the assistance of placing materials. After the materials are mixed, they are directly transported to the construction site, and the discharge port can discharge materials at 270 degrees around the body. It is this highly automated procedure that saves a lot of labor costs.
In addition, the technology and detailed design of the bucket can make the automatic process to a higher level. For example, the bucket capacity of the high-weight concrete mixer is not only large, the bottom of the arc structure is very smooth, whether loading or unloading, and the serrated strip in the middle of the bucket can directly cut the bag when loading cement, Workers just need to throw the cement bag into the bucket... Details like this are not only carefully designed, but also more efficient.
