Specific implementation mode
A kind of four spiral main concrete mixer of double drive of the utility model is made in detailed below with reference to Figure of description
Explanation.
As shown in Figure 1, Figure 2, Figure 3 shows, the four spiral main concrete mixer of a kind of double drive of the utility model, structure packet
It includes transmission device 1, agitator tank 3, agitating device 2 and shedding mechanism 4, is equipped with agitating device 2 in the agitator tank 3, under agitator tank
Portion is equipped with shedding mechanism 4, and the both ends of the agitator tank 3 are respectively equipped with transmission device 1, and the agitating device 2 is that two stirrings are led
The both ends of axis, the stirring main shaft are coupled transmission device 1 respectively, and the transmission device is by motor 6, speed reducer 10, big belt
Wheel 9, V bands 8 and small belt pulley 7 are constituted;The stirring main shaft is equipped with double helix stirring blade.The double helix stirring blade is
Helical-ribbon type, on 13 axial direction of stirring main shaft, the phase angle between adjacent stirring blade is 45 °, stirring main shaft it is crosscutting
The phase angle of two stirring blades on section is 180 °.Every stirring main shaft 13 stirs for double helix, and two main shafts are just formed
Four augers.The agitating device of four spiral forms can effectively improve the mixing effect in inefficient area, and efficiency improves 15%, stirring

The case where material and toll bar, occurs.
The axle end sealing device of stirring main shaft end uses the form of packing aerating sealing, and pressure is formed using the gentle body of packing
Power chamber, prevents mud from entering axle end sealing device.It only needs to be monitored gas pressure in entire whipping process, makes its maintenance
In certain pressure range, it is ensured that the validity of sealing.Common host mainly fills up shaft end seal by butter in the market
The internal voids of device, to prevent mud from entering axle end sealing device.Butter is mixed into the concrete of stirring, to the product of concrete
Matter has certain influence, even destructive influences.Therefore, above-mentioned axle end sealing device, production process do not need butter, stir
The concrete mixed out is free of grease, is suitble to require concrete quality high customer demand.
Motor 6 drives small belt pulley 7 to rotate in transmission device 1, is transmitted by V bands 8, and big belt pulley 9 and then rotates, great Pi
Belt wheel 9 is connect with the input terminal of speed reducer 10, and to drive speed reducer 10 to operate, the synchronization end of speed reducer 10 is connected with synchronous
Axis device 11 ensures that the output rotating speed of two speed reducers 10 is identical, and the output end of speed reducer 10 is the flange of ring flange and collar bush 12
Disk is connected, and collar bush 12 and stirring main shaft 13 are connected by scale-up version locking plate 14, and two agitating shafts 13 are with deceleration
Machine 10 is done to be rotated backward at the same speed.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this practicality
It is novel to be confined in the shown concrete structure and the scope of application, thus it is every be possible to be utilized corresponding change and wait
Jljl belongs to the apllied the scope of the claims of the utility model.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
