JS2000 concrete mixer is a mechanical device that uses pressure to continuously transport concrete along pipelines. It consists of a pump body and a conveying pipe, mainly divided into gate valve concrete conveying pumps and S-valve concrete conveying pumps. However, according to the structural form, it can be further divided into piston type, extrusion type, and water pressure diaphragm type. The pump body is mounted on the chassis of a car, and is equipped with a flexible or bendable fabric rod to form a pump truck. It is mainly used in building construction, bridge and tunnel construction.
The feeding system of JS2000 mixer consists of hoisting mechanism, feeding rack, hopper, feeding nozzle and other parts.
The mixing system of JS2000 mixer is composed of electric motor, pulley, reducer, open gear, mixing drum mixing device, oil supply device, etc.
The electric motor is directly connected to the cycloidal pin reducer, and the two output shafts of the reducer drive the horizontally configured mixing shaft to rotate at a constant speed in reverse through split gears.
The circular arc part of the mixing drum is welded, and there are five types of lining plates embedded inside the mixing drum, all of which are fastened to the drum body with countersunk screws.

The unloading system consists of unloading hopper, air pump, directional valve, air distribution valve, cylinder, electrical and other mechanisms.
The discharge door is installed at the bottom of the mixer and is pneumatically discharged through a cylinder. The opening and closing position of the discharge door can also be controlled, and the sealing of the discharge door can be ensured by adjusting the position of the sealing strip.
The manual unloading lever is used for emergency unloading during temporary power outages and for unloading in case of cylinder failure. It should be removed regularly to prevent injury.
