Preferably, the screw grooves are formed in two opposite sides of the scraping piece, the two sides of the screw sleeve are fixedly connected with the grooved lug plates through the support, and the adjacent grooved lug plates and the screw grooves are connected with fastening bolts in a common screw thread mode.

Preferably, the rear side fixedly connected with draw runner plate of agitator tank, the inside sliding connection of draw runner plate has the slider, and passes through U type pole fixed connection between slider and the thread bush.

Preferably, the bottom of the thread bush is fixedly connected with an ash shielding cylinder.

Preferably, a discharging pipe is communicated with the bottom of the stirring tank.

Preferably, the bottom fixedly connected with a plurality of support column of agitator tank, and a plurality of support column is encircleing equidistant array setting.

Advantageous effects

The utility model provides a concrete mixer. Compared with the prior art, the method has the following beneficial effects: according to the utility model, the screw sleeve is arranged on the surface of the rotating shaft in a threaded manner, and the detachable scraping blades are arranged on the two parts of the screw sleeve, so that when the driving motor drives the rotating shaft to stir the mixed material by the stirring rod, the rotating shaft can also drive the scraping blades to scrape the inner wall of the screw sleeve up and down, the scraping can drive the inner wall above the liquid level of the mixed material of the stirring tank to prevent the problem that the subsequent cleaning is difficult, and the scraping blades are driven to be detached, so that the subsequent replacement is convenient.
