[0030] An embodiment of the present utility model provides a vertical mortar mixer, as Figures 1-4 shown, including a mixing tank 1 with an opening at the top, a driving motor 2 is installed at the bottom of the mixing tank 1 through a mounting frame, the output end of the driving motor 2 is connected to a rotating rod 3 through a rotating shaft and a coupling, the rotating rod 3 is located in the inner cavity of the mixing tank 1, a mixing rod 4 for revolving and mixing the material is fixed on the outer wall of the rotating rod 3, and a mixing mechanism 5 distributed on the rotating rod 3;

[0031] The mixing mechanism 5 includes a transmission unit and a mixing unit;

[0032] The transmission unit is used to drive the mixing unit in a revolving state to rotate self.

[0033] The mixing unit in a self-rotating state is used to horizontally mix the bottom of the material to improve the mixing efficiency.

[0034] The transmission unit includes a support rod 501, a fixed rod 502, a first bevel gear 503 and a second bevel gear 504;

[0035] The support rod 501 is fixed at the edge of the top opening of the mixing tank 1 and extends to the axial center position of the rotating rod 3, and the support rod 501 is used to provide support for the fixed rod 502;

[0036] The fixed rod 502 is fixed at the center of the bottom end of the support rod 501 and extends into the inner cavity of the rotating rod 3. The fixed rod 502 is used to provide support for the first bevel gear 503;

[0037] The first bevel gear 503 is press-fitted at the bottom end of the fixed rod 502. The first bevel gear 503 is used to provide a reaction force for the second bevel gear 504 that moves circumferentially;

[0038] The second bevel gear 504 is press-fitted at one end of the transmission rod 505 and is located in the inner cavity of the rotating rod 3. The rotating second bevel gear 504 is used to drive the transmission rod 505 to rotate.

[0039] The stirring unit includes a transmission rod 505 and a stirring blade 506;

A seal for preventing mud from entering is provided at the connection between the transmission rod 505 and the rotating rod 3. The number of stirring blades 506 is set to be multiple. The multiple stirring blades 506 are axially distributed on the outer wall of the stirring blade 506 and axially and evenly arranged on the outer wall of the transmission rod 505. The outer wall of the fixed rod 502 is rotatably connected to the inner wall of the end of the rotating rod 3. The fixed rod 502 and the first bevel gear 503 are both fixed and immovable.
