When the barrel mouth of the mixing barrel 3 is tilted downward, the discharging assembly stops working, and the dough can be discharged conveniently at this time.

[0056] After the discharging is completed, the discharging motor 5 drives the driving shaft 4 to rotate in the direction, and the mixing barrel 3 rotates in the opposite direction. The mixing barrel 3 drives the limiting shaft 302 to re-enter the strip groove 201 from the avoidance opening 202, and the discharging motor 5 stops working. The second telescopic rod 9 drives the horizontal rod 10 to rise, and the horizontal rod 10 abuts against the top of the strip through groove. The telescopic end of the first telescopic rod 7 drives the supporting shaft 8 to move and makes the supporting shaft 8 completely enter the second through hole. The telescopic end of the first telescopic rod 7 contracts, and the horizontal rod 10 drops synchronously. The mixing barrel 3 drops synchronously with the horizontal rod 10 under the action of its own gravity. When the limiting shaft 302 returns to the end of the strip groove 201, the first telescopic rod 7 stops working.
