After that, the stirring device 9 starts to run at high speed inside the mixing bucket 8 to drive the mortar raw materials with the mixing ratio completed to move, so as to mix them quickly. After the mixing is completed, the lifting device 6 starts again to push the stirring device 9 to move upward out of the inside of the mixing bucket 8, and push the mixing bucket 8 to displace from the inside of the inner through groove 5 to the outer extension end of the support device 7, so that the mixing bucket 8 is separated from the inside of the fixed box 1 for discharging.

[0033] The utility model arranges the mixing ratio bucket 3 inside the fixed box 1 and makes the material guiding pipe 4 at its bottom extend to the inside of the inner through groove 5.
