[0049] Working principle:

[0050] When using the improved dough mixer of the utility model, the hammer body 611 and the first rod body 612 are first disassembled, flour and water are added into the mixing barrel 3, and then the hammer body 611 and the first rod body 612 are installed and fastened by the collar 616 and the fastening bolt 617. Then, the upper and lower first connecting shafts 22 can be driven to rotate by the first motor 21, thereby driving the upper and lower first sprocket wheels 23 and the second sprocket wheel 24 to rotate, and then driving the upper and lower second connecting shafts 26 to rotate, and finally driving the stirring rod 5 and the mixing drum 3 fixedly connected with the two second connecting shafts 26 to rotate, so as to achieve the stirring effect of the flour and water inside the mixing drum 3, which will slowly make the flour stick together to form dough. At the same time, the second motor 41 drives the first pulley 42 to rotate, and drives the second belt pulley 44 through the belt 44. The wheel 43 rotates, thereby driving the first support shaft 45 and the first gear 46 to rotate, and the second gear 48 and the second support shaft 47 are driven to rotate through the first gear 46, thereby driving the connecting block 49 and the first connecting shaft 410 thereon to rotate. Since the first connecting shaft 410 is arranged at the other end of the connecting block 49, the first connecting shaft 410 rotates in a circle with the second support shaft 47 as the center and the length of the connecting block 49 as the radius, thereby driving the first connecting rod 411, the second connecting shaft 412, and the second connecting rod 413 to move up and down periodically, and finally the striking hammer 6 can be pushed up and down to beat the dough. Through this simultaneous mixing and beating operation, the dough quality with better and more resilient can be guaranteed. Finally, the movable door 31 can be opened to take out the dough, which is very convenient.
