The composition of concrete mixers

The concrete mixer consists of a mixer, a drive system, a feeding system, a water supply system, a rack and a leg, an electrical control system, and a stirrer, a stirrer, a shaft end seal, a liner, a discharge door lubrication system, Hongbin company to come for everyone to summarize the structure of concrete mixer structure, for your reference.

Concrete mixer composition structure:
(1) Stirring device:
Mixing cylinder, stirring shaft, stirring arm, stirring blade and side blade. The stirring cylinder is equipped with two horizontal configuration mixing shaft, each shaft is equipped with stirring blades. The mixing blades on both ends of the mixing cylinder are respectively provided with side blades to scrape off the concrete on the end face and change the flow of concrete.

(2) Drive system:
Transmission mode by transmission can be divided into two kinds: respectively, mechanical transmission and hydraulic drive. Hydraulic drive has a light weight, small size, tight structure, driving force and other characteristics, but taking into account the current domestic situation, although the hydraulic motor than in the past to improve the quality, but expensive, for the general cost of the mixer is too high, Not economical, so we use the traditional mechanical transmission. Transmission system consists of motor, pulley, gear box, open gear and other components.

(3) feeding system:
The feeding system consists of hoisting mechanism, feeding rack, hopper, feed hopper, pulley and so on

(4) Water supply system:
Water supply system is the motor, water pump, throttle and piping and other components. Start the pump, you can inject the mixing cylinder, the flow of water through the gate valve regulation, the total water supply by the time relay control. When the button goes to "time control"

Position, the pump will run according to the set time and automatically stop, when the button to "manual" position, can be continuous water supply.

(5) Rack and legs:
① rack:

According to the overall layout and size requirements, according to the overall requirements of the specific requirements of the channel, angle welded together, and according to the strength of the assembly welding riveting together, support the host, and the various parts of the spatial position fixed to form a whole.

② Outrigger: Due to the large capacity of the machine, according to the national urban construction regulations require discharge height greater than 1.5m, with long legs with the use. Stirring long legs support to meet the requirements. The legs can be removed during transport. Short legs are used for transport status,

Removing the long legs prevents the components of the rack from being damaged by contact with the vehicle.

(6) Electrical control system:
The electrical control system needs to control the main drive motor of the JS750 concrete mixer, the motor of the water supply system, the feeding, the cutting and the like. All electrical control components are located in the distribution box. Electrical components control to meet the requirements: the main motor can be jog to meet the installation and repair process requirements. Electrical control circuit with air switch, fuse, thermal relay with short circuit protection, overload protection, phase protection function, all control buttons and air switch handle and indicator lights are arranged in the distribution box door, and a door lock The Distribution box electrical components installed in a piece of iron, safe and reliable, easy operation and maintenance.
