[0036] An embodiment of the present application provides a dough mixing blade 2, which is applied to a dough mixer. The dough mixing blade includes: a curved kneading board 21 and a stirring shaft 22 provided on one side of the length direction of the kneading board 21. The curved kneading board 21 can play a role in fully kneading and pressing the dough to quickly form the dough.

[0037] In some possible implementation manners, the length of the kneading board 21 is shorter than the length of the stirring shaft 22, and a kneading gap 3 is formed in the length direction. When the dough mixing blade 2 is horizontally installed in the dough mixing barrel 1, the kneading gap 3 correspondingly becomes a horizontal gap 32.

[0038] In some possible implementation manners, the kneading gap 3 is set to a left-right symmetric structure.

[0039] In some possible implementation manners, the upper and lower widths of the kneading gap 3 are the same.

[0040] In some possible implementation manners, the projection of the dough mixing blade 2 in the length direction is one or more arcs, and the projection in the width direction is a straight line. That is, the kneading board 21 is set to a plate-like structure with one or more arc surfaces, which can play a role in increasing the contact area and guiding, and can fully knead and press the dough to quickly form the dough.

[0041] As an example, the projection line in the length direction is an arc with a central angle less than 30°.

[0042] As another example, the projection in the length direction is two arcs connected in reverse, and the central angle of each arc is less than 15°.

[0043] In some possible implementation manners, the stirring shaft 21 is set to a hollow cylindrical structure, so that the transmission shaft 103 can be placed inside the stirring shaft 21 to drive it to rotate synchronously.

[0044] In some possible implementation manners, the inner side surface of the stirring shaft 21 is set to an inner hexagonal shape, and the inner hexagonal shape can play a good role in synchronous rotation, and has a simple structure and is convenient for processing.

[0045] In some possible embodiments, the connection between the dough kneading blade and the stirring shaft is provided with a reinforced wide edge in the shape of a hillside, so as to provide a firm and powerful support for the dough kneading board 21, which can not only increase the dough kneading force, but also prevent the dough kneading board 21 from breaking and being damaged.

[0046] The embodiment of the present application also provides a dough kneading assembly, which includes a dough kneading bucket 1 and a dough kneading blade 2 detachably arranged in the dough kneading bucket 1 as described above. Wherein, the dough kneading blade 2 is configured as the dough kneading blade 2 described in the foregoing embodiment and any at least one implementation manner thereof. Correspondingly, its technical effects also completely extend to this embodiment and will not be elaborated herein.

[0047] The embodiment of the present application also provides a dough kneading machine, which includes a driving motor 101 arranged in a main machine base 100 and the above-described dough kneading assembly detachably connected to the driving motor 101 through a transmission shaft 103. Wherein, the dough kneading assembly is configured as the dough kneading assembly described in the foregoing embodiment and any at least one implementation manner thereof. Correspondingly, its technical effects also completely extend to this embodiment and will not be elaborated herein.
