[0034] See Figures 1 to 8As shown, a dough mixer includes a frame 1, a material hopper 3 mounted on the frame 1, an auger 6 rotatably mounted in the material hopper 3, and a drive device 2 for driving the auger 6 to rotate. The auger 6 includes a first hinge rod 61 and a second hinge rod 62 rotatably connected to the frame 1. The first hinge rod 61 and the second hinge rod 62 are respectively located on both sides of the material hopper 3 and pass through the material hopper 3. An auger body 63 is disposed between the first hinge rod 61 and the second hinge rod 62. Fasteners 64 are provided on the side of the auger body 63, and the fasteners 64 control the auger body 63 to be detachably connected to the first hinge rod 61 and the second hinge rod 62. The drive device 2 drives the first hinge rod 61 or the second hinge rod 62 to move and drive the auger body 63 to rotate. In this structure, the auger 6 includes the first hinge rod 61, the second hinge rod 62 and the auger body 63 that are detachably connected. The first hinge rod 61 and the second hinge rod 62 are respectively set on both sides of the material bucket 3 and inserted into the material bucket 3. When the auger 6 needs to be disassembled for maintenance or cleaning, the user only needs to disassemble the auger body 63 from the first hinge rod 61 and the second hinge rod 62, which facilitates the assembly, production and disassembly and maintenance of the dough mixer. The user can also disassemble the auger body 63 for cleaning, which helps to keep the dough mixer clean and hygienic.

[0035] The driving device 2 includes a drive motor 21 and a transmission structure 22. A transmission part 621 is provided on the second hinge rod 62. The transmission structure 22 cooperates with the transmission part 621 and drives the auger 6 to rotate through the transmission part 621. In this embodiment, the first hinge rod 61 and the second hinge rod 62 have similar structures, and the main difference is whether or not they have a transmission part 621.

[0036] In this utility model, the auger body 63 has connecting portions 631 at both ends, and each connecting portion 631 has a positioning groove 632. The first hinge rod 61 and the second hinge rod 62 each have positioning protrusions 611 that are adapted to the positioning grooves 632. The fasteners 64 control the auger body 63 to be relatively fixed with the first hinge rod 61 or the second hinge rod 62, and keep the positioning grooves 632 and the positioning protrusions 611 in cooperation. The positioning grooves 632 and the positioning protrusions 611 facilitate the positioning connection between the auger body 63 and the first hinge rod 61 or the second hinge rod 62, and facilitate the rapid assembly of the auger body 63.

[0037] Preferably, the positioning grooves 632 at both ends of the auger body 63 are identical and symmetrically arranged. The positioning protrusions 611 on the first hinge rod 61 and the second hinge rod 62 can both cooperate with the positioning grooves 632 at both ends of the auger body 63. Since the positioning protrusions 611 on the first hinge rod 61 and the second hinge rod 62 can both cooperate with the positioning grooves 632 at both ends of the auger body 63, the auger body 63 can be installed upright or backward during use, which is convenient for users to install flexibly and facilitates the quick assembly of the dough mixer.

[0038] In this embodiment, the positioning groove 632 and the positioning protrusion 611 cooperate to form a cylindrical structure by combining the positioning protrusion 611 and the connecting part 631. This structure avoids the residue of dough at the connection position between the positioning protrusion 611 and the connecting part 631 during use, making it convenient for users to use and clean the auger 6.

A flip cover 4 is movably mounted on the frame 1. The flip cover 4 can be fastened to the material bucket 3 and restrict the relative rotation of the material bucket 3 and the frame 1. The material bucket 3, which is rotatably mounted on the frame 1, makes it easy for the user to take out the kneaded dough. The flip cover 4 can not only prevent foreign matter from entering the material bucket 3 during the kneading process, but also restrict the relative rotation of the material bucket 3 and the frame 1, which is conducive to the stable installation of the material bucket 3 and prevents the material bucket 3 from tilting and flipping during the kneading process.

[0040] The material bucket 3 described in this utility model is provided with a connecting buckle 5, and the flip cover 4 is provided with a hook 43 that matches the connecting hole. The connecting buckle 5 and the hook 43 cooperate to keep the flip cover 4 connected to the material bucket 3. The setting of the connecting buckle 5 and the hook 43 is conducive to the stable connection between the material bucket 3 and the frame 1, and avoids the material bucket 3 tilting and flipping during the kneading process.

[0041] In this embodiment, the flip cover 4 is rotatably mounted on the frame 1 via a hinge 41, and a handle 42 is provided on the flip cover 4, which allows the user to control the rotation of the flip cover 4.

[0042] Rotating seats 31 are respectively provided on both sides of the material bucket 3, and mounting seats 11 rotatably connected to the rotating seats 31 are provided on the frame 1. The first hinge rod 61 and the second hinge rod 62 are respectively rotatably arranged in the rotating seats 31 on both sides of the material bucket 3 and can rotate relative to the frame 1 through the rotating seats 31. The arrangement of the rotating seats 31 and the mounting seats 11 is conducive to the stable installation of the material bucket 3, avoids the first hinge rod 61 and the second hinge rod 62 from being damaged by excessive force, and helps to extend the service life of the dough mixer.

[0043] The rotating seat 31 of this utility model is provided with an installation groove 311 facing the material bucket 3. A bearing 32 is provided in the installation groove 311. The first hinge rod 61 and the second hinge rod 62 are each provided with a hinge part 612 and a limiting wall 613. The hinge part 612 is adapted to the inner shell of the bearing 32, and the limiting wall 613 abuts against the bearing 32 and makes the bearing 32 press against the bottom of the installation groove. The installation groove 311 facing the material bucket 3 is convenient to limit the overall length of the auger 6, and prevent the first hinge rod 61 and the second hinge rod 62 from shifting to both sides of the material bucket 3 after long-term use. It is also beneficial to the positioning connection between the auger body 63 and the first hinge rod 61 and the second hinge rod 62, and facilitates the quick installation and disassembly of the auger body 63.

[0044] In this embodiment, the rotating seat 31 and the material bucket 3 are detachably connected. The side of the material bucket 3 is provided with a through hole 34.
