DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of those skilled in the art, the utility model is further explained below in conjunction with examples and drawings, and the content mentioned in the implementation manner is not the limitation of the utility model. The utility model is described in detail below in conjunction with the drawings.

[0018] As Figure 1 And Figure 2 As shown in the utility model provides a kind of bottom drive's stirring device, including stirring barrel 1 and setting in stirring barrel 1 stirring mechanism, the inner bottom wall of the stirring barrel 1 is provided with let - go hole 11 and hollow protection column 12, protection column 12 is communicated with let - go hole 11, stirring mechanism includes drive module 3, transmission shaft 4 and stirring module 5, drive module 3 is driven connection stirring module 5 by transmission shaft 4, transmission shaft 4 is movably set in protection column 12 and protrudes from the top of protection column 12 to stirring barrel 1, stirring module 5 is installed at the top of transmission shaft 4 and located in stirring barrel 1.

[0019] When actually used, the bottom of the stirring barrel 1 is provided with a base 18, and the drive module 3 is arranged on the base 18. The base 18 is provided with a plurality of trundles 19. Compared with the prior art, the utility model discloses that the drive module 3 is installed at the bottom of the stirring barrel 1, the transmission shaft 4 is inserted into the stirring barrel 1 after passing through the protection column 12 and is connected to the stirring module 5, so that the effect of stirring the material in the stirring barrel 1 is also achieved. When the utility model is used, a top cover can be provided to cover the top of the stirring barrel 1. Since the top cover does not provide a stirring paddle, and the stirring module 5 is not inserted into the stirring barrel 1 from top to bottom, the stirring module 5 and the drive module 3 do not interfere with the material being fed into the stirring barrel 1, which is beneficial for feeding.

[0020] In the embodiment, the protection column 12 is welded to the inner bottom wall of the stirring barrel 1, and the protection column 12 is located directly above the accommodation hole 11. The protection column 12 is fixed by being welded to the stirring barrel 1, so that the stability of the connection between the two is ensured, and material leakage between the two is avoided, and the safety of the stirring mechanism is protected.
