Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the utility model. That is, in some embodiments of the utility model, such implementation details are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

Example one

Referring to fig. 1, a dry-mixed mortar mixer is different from a common blade mixer, the mixing part of the dry-mixed mortar mixer is a Mobius mixing blade 51 with a Mobius annular structure, the Mobius mixing blade 51 can convey the rear materials to the front through a central space in the rotating process, and the restriction and mixing flow is realized in the conveying process, the dry-mixed mortar mixer specifically comprises a bracket 1, a driving motor 2, a variable speed transmission case 3, a horizontal mixing drum 4, a blade mixing part 5 and a conveying pipe 6, the horizontal mixing drum 4 is fixedly arranged at the top of the bracket 1, the variable speed transmission case 3 is arranged at one side of the horizontal mixing drum 4, the input end of the variable speed transmission case 3 is connected with the driving motor 2, the output end of the variable speed transmission case 3 is connected with the blade mixing part 5 in the horizontal mixing drum 4, the conveying pipe 6 is arranged at the bottom of the horizontal mixing drum 4, the blade mixing part 5 comprises a rotating shaft 53 and the Mobius mixing blade 51, the plurality of mobius stirring vanes 51 are linearly arranged along the central axis of the rotating shaft 53.

This device uses Mobius stirring vane 51 to replace traditional slice stirring vane for the material stirring is more abundant, and stirring efficiency is higher.

Example two

Referring to fig. 1, 2 and 3, basically the same as the first embodiment is different in that the blade stirring section 5 is further provided with a helical stirring blade 52, and the helical stirring blade 52 and the mobius stirring blade 51 cooperate to form an internal and external circulation stirring structure.
