put into two kinds of cement clinker respectively in the rubbing crusher of difference, after will mixing the interpolation material and put into the third rubbing crusher simultaneously, be connected three connecting pipes 31 of agitator 3 with three rubbing crusher discharge end respectively, treat that the mixed raw materials in the agitator 3 increases after certain quantity, start agitator motor 71, agitator motor 71 drives the (mixing) shaft 72 and rotates, under the resistance of mixed raw materials, installation section of thick bamboo 73 rotates with (mixing) shaft 72 relatively and promotes puddler 731 and rotate to the level to supporting tight piece 722, behind first dog 7223 supported tight second dog 733, make (mixing) shaft 72 drive installation section of thick bamboo 73 and puddler 731 rotation stir the mixed raw materials in the agitator 3 through the cooperation between first dog 7223 and the second dog 733.

After the raw materials stirring is accomplished, the staff can place the storage instrument under discharging pipe 4, then rotate fixed pipe 41 through the stress application pole 411 and promote the sealing wheel 42 and support the back tightly with the cooperation of drive wheel 734, under the drive of drive wheel 734, the finished product cement in the agitator 3 can be exported in the storage instrument in the agitator 3 under the promotion of discharge shaft 43 and the play flitch 44 that is the heliciform.

When the stirring barrel 3 needs to be cleaned, the first motor 52 is started to drive the first screw 51 to rotate through the first worm 53 and the first worm wheel 54 so as to push the mounting table 21 to descend, and simultaneously, the second screw 61 is driven to rotate through the cooperation of the first gear 62 and the second gear 63 so as to drive the mounting frame 22 and the barrel cover 221 to ascend. After the mounting table 21 descends to a proper position, the hand wheel 851 rotates the second worm 85, the second worm 85 drives the second worm wheel 822 to rotate, the second worm wheel 822 drives the third screw rod 81 to slide downwards to support the stirring barrel 3, and then the stirring barrel 3 is pushed out from the mounting table 21 for cleaning.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
