Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of flushing mechanism of concrete mixer, including cylinder 1 and agitating shaft 2 are fixed with paddle on agitating shaft 2
Leaf 3, is equipped with central passage 4 in the agitating shaft 2, and 2 outer wall of agitating shaft is fixed at least one wash tub pipe 5, wash tub pipe 5 with
Blade 3 is interspersed, and the end of wash tub pipe 5 is equipped with unidirectional flashing valve 6, one end of agitating shaft 2 and the output shaft phase of speed reducer 7
Even, the other end of agitating shaft 2 is connected by water seal 8 with water inlet pipe 9, and the central passage 4 in agitating shaft 2 is communicated with water inlet pipe 9, institute
The water inlet pipe 9 stated is connected with water pump 10.Due to taking above-mentioned technical proposal, when needing to rinse after blender works, open
Dynamic water pump 10, pressure water enter the central passage 4 in agitating shaft 2 by water inlet pipe 9, and under hydraulic pressure effect, unidirectional flashing valve 6 is beaten
It drives capable water spray into, agitating shaft 2 can at this time rotated, sealing function is played in water seal 8, and agitating shaft 2 drives the dynamic component of water seal 8 to turn
