Agitating unit, respectively the agitating unit is including in horizontally disposed rotary shaft 2 and multiple rotating disks 3, multiple rotating disks 3 are pacified
It is distributed in rotary shaft 2 and in a row；Multiple grooves 4 are equipped with the peripheral side of each rotating disk 3；In the present embodiment, rotate
Axle 2 is horizontally disposed with, and is placed in the inside of mixing drum 1, naturally it is also possible to only allow the middle part of rotary shaft 2 to be placed in mixing drum 1, two ends
The outside of mixing drum 1 is extended to, its two ends rotates with the barrel of mixing drum 1 and is connected.
Driver element, the driver element is connected with rotary shaft 2 and stirred so that the groove 4 in driving rotating disk 3 is into and out
Mix inside cylinder 1；In the present embodiment, driver element can be motor.
Concrete is added in the mixing drum 1, drives rotary shaft 2 and rotating disk 3 to rotate using driver element, is allowed on rotating disk 3
Groove 4 is constantly inside turnover mixing drum 1, and when groove 4 is to bottom offset, concrete enters in groove 4, when groove 4 is gradually increasing,
Concrete is gradually flowed out out of groove 4, and lower concrete is thus constantly flipped up, in realization by such iterative cycles
Side is constantly mixed with lower concrete, and mixing efficiency is high, good mixing effect.
In order to further improve in mixed effect, the present embodiment, the groove 4 is close to the midpoint one end of rotating disk 3 and the midpoint of rotating disk 3
Between line and groove 4 center line between angle be β, β is 10-80 degree, and general β takes 30-60 degree；With reference to Fig. 2, rotating disk
3 rotate counterclockwise, and groove 4 is not being radially arranged along rotating disk 3, but are set into skewed, form angle β, pass through
So design, facilitate concrete to enter in groove 4, slid while slowing down concrete out of groove 4, the concrete allowed in groove 4
The bigger height of lifting, it is so further to improve mixed effect.
In order to further improve in mixed effect, the present embodiment, the center line of two rotating disks 3 of arbitrary neighborhood is not conllinear；
With reference to Fig. 2, the concrete in groove 4 can produce impact when being slid from groove 4, drive concrete to be spread to surrounding, if adjacent
The inner concrete of groove 4 in two rotating disks 3 slides simultaneously, while if impact, meeting reciprocal influence is unfavorable for concrete to four
Week diffusion, by above-mentioned design, beneficial to concrete to around spreading, improves mixed effect.
In order to further improve in mixed effect, the present embodiment, along the length direction of rotary shaft 2, the 1st, the 3rd, the 5th
The centerline collineation of individual ... and n-th rotating disk 3, is respectively positioned in first straight line；2nd, the 4th, the 6th ... and m-th
The centerline collineation of rotating disk 3, is respectively positioned in second straight line；And above-mentioned first straight line and second straight line are distributed in rotary shaft 2 respectively
The both sides of center line；Wherein, N=2X-1, M=2X, X >=1, X are integer；So concrete also allows for, to around spreading, mixing
It is more uniform；Total operates steadily simultaneously, stress equalization, reduction abrasion, improves service life；Rotating disk 3 is distributed in not
Same height, this makes it possible to be overturn using groove 4 to the concrete of different height, further improves mixing effect
Really.
In order to further improve in mixed effect, the present embodiment, the one end of the groove 4 away from the center line of rotating disk 3, which is provided with, prolongs
Extending portion 5, centerline direction of the extension 5 along groove 4 is set, and the groove 4 is in communication with the outside by extension 5；Pass through increase
Extension 5, slows down the slip velocity of the inner concrete of groove 4, while can be more mixed using storage in extension 5 and groove 4
Solidifying soil, can so lift more concrete, further improve mixed effect.
The present embodiment also includes：Container 6, tumbler 7, the tumbler 7 are arranged in rotary shaft 2 and rotated with rotary shaft 2
Connection, the inside of tumbler 7 is provided with medium temporarily providing room 8, and the medium temporarily providing room 8 is connected by pipeline 9 with container 6；Rotate
Part 7 is placed in inside mixing drum 1, it is of course also possible to allow one end of rotary shaft 2 to extend to the outside of mixing drum 1, so allows tumbler
7 are arranged on the end, and such tumbler 7 can be just placed in outside mixing drum 1.
Medium receiving space 10 is provided with along its centerline direction in the rotary shaft 2, the medium receiving space 10 and medium are temporary
Space 8 is deposited to connect.
The inside of at least one rotating disk 3 is provided with flow of media passage 11, and at least one groove 4 is by upper on above-mentioned rotating disk 3
Mass flow circulation passage 11 is given an account of to connect with medium receiving space 10；In order to improve mixed effect, it can allow on each rotating disk 3 and be designed with
Flow of media passage 11, while allowing flow of media passage 11 to be connected with corresponding groove 4, what is so mixed is more uniform.
Need to add other materials, such as water in ready-mixed concrete, water is added in container 6, water enters through piping 9 and is situated between
Matter temporarily providing room 8, then sequentially enters medium receiving space 10, flow of media passage 11, is finally discharged out of groove 4, so
Water can enter in lower concrete, and compared to relatively directly water is passed through in mixing drum 1, mixed effect is greatly improved.
In order to further improve in mixed effect, the present embodiment, during the quantity of agitating unit is two, two agitating units
Rotary shaft 2 rotation direction it is opposite；So advantageously overturn in concrete, improve mixed effect, also improve mixing
Efficiency.
In order to further improve mixed effect, the present embodiment also includes：
Power unit, the power unit is connected with rotary shaft 2, to drive rotary shaft 2 along its centerline direction displacement；
In the present embodiment, power unit includes support A and telescoping cylinder, and rotary shaft 2 is rotated with support A and is connected, and branch is driven using telescoping cylinder
Frame A drives the horizontal displacement of rotary shaft 2, so allows the concrete of horizontal direction to mix, greatly improves mixed effect.In order to just
In rotator shift, so, moving resistance can be reduced on rotating disk 3 along the multiple through holes of its centerline direction setting, improves mixing
Effect.
