2) The power take-off power take-off device is a kind of power output device. It removes the engine power without changing the inherent performance of the original car, and drives the hydraulic pump through the coupling to realize the feeding and stirring. , discharge and other functions.
3) Agitator The shape of the agitator is a cone at the two ends and a cylinder in the middle. It is mainly composed of a cylinder, a connecting flange, a raceway, and a stirring blade. According to the size of the agitating volume consists of a single cone or a double cone, the section is closed by the head and the flange is welded. The rear cone has an annular path welded to a circle perpendicular to the plane of the mixer drum. Two continuous ribbon spiral blades are welded symmetrically from the mouth to the inner wall of the cylinder bottom. In order to enhance the stirring effect, auxiliary stirring blades are installed between the two spiral blades in the middle and lower part of the mixer drum.
4) Feed and discharge device It mainly consists of feed hopper, unloading hopper, slide chute and lifting mechanism. It mainly finishes loading and unloading of the well-mixed concrete. It is installed at the rear of the mixer truck.
5) Sub-frame The sub-frame is the base part of the whole mixer and carries the weight of the entire top coat and concrete. Secured to the chassis of the car by U-bolts and connecting plates. The rubber slats between the subframe and the main girder of the car act as shock absorption and anti-attack.
6) Front and rear brackets The front and rear brackets are the main support components of the mixing drum. The angle of the upper plane of the front and rear brackets determines the installation angle of the mixing cylinder.
7) Speed ​​reducer The speed reducer is a support part and a power part of the agitator body. It drives the agitator barrel to rotate and act as a decelerator.
8) Operating System The operating system controls the rotation of the mixer drum and the speed of the mixer drum. The steering control of the mixing drum is driven by the pull rod drive of the control system to drive the hydraulic pump variable cylinder swing rod to realize the reversal. At the same time, if the swing angle of the variable rod is increased or decreased, the pump flow rate can be adjusted slightly. The rotational speed control of the mixer drum is mainly through pulling the lever of the operating system to pull the throttle cable of the chassis engine, increasing or decreasing the engine speed to adjust the rotation speed of the hydraulic pump, thereby regulating the flow of the hydraulic pump, and achieving the feeding, discharging and stirring of the mixing drum. And stop function.
The composition of the mixer
1) Mixer Chassis The chassis of the mixer truck is produced by the automobile factory. It is the supporting part of the entire top coat and can walk on its own. It is one of the core components of the vehicle.
