Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1, concrete mixer, including mixing drum, mixing drum central axis are provided with activity even from top to bottom
The transverse link 5 in parallel arrangement, the end set of transverse link 5 are provided on the agitating shaft a and agitating shaft b connect, agitating shaft a
There are longitudinal paddle board 6, agitating shaft a to be driven by motor a1；Transverse link 5 is set as several, and adjacent transverse link 5 is equally
Parallel arrangement, and it is disposed as cylinder rod, with certain anti-impact force and resistance to collision, stability of strutting system is stronger, indulges
It is set as rectangular harden structure, the 6 perpendicular erection of transverse link 5 and longitudinal paddle board to paddle board 6.
Carrying out practically process is：Concrete to be mixed is put into mixing drum, motor a1 rotations drive agitating shaft a rotations
Turn, transverse link 5 on agitating shaft a and longitudinal direction paddle board 6 synchronize do and move clockwise or counterclockwise, cylinder upper end is mixed
