Description
Technical Field
[0001] The utility model relates to the technical field of sand mixers, in particular to a high-efficiency sand mixer. Background Art
[0002] A sand mixer is a device that mixes the various components in the molding sand evenly and effectively coats the surface of the sand particles with a binder.

[0020] In this embodiment, a rotating rod 2g is arranged between the two first stirring plates 2f, and the rotating rod 2g extends downward into the conical barrel 5. A spiral blade 2g-1 is arranged on the outer wall of the rotating rod 2g. The upper ends of the rotating rod 2g are connected to the two first stirring plates 2f via connecting plates 2g-2 on both sides.
[0021] When the two first stirring plates 2f are driven to rotate by the load-bearing ring 2b, the two first stirring plates 2f drive the rotating rod 2g to rotate through the connecting plate 2g-2, and the spiral blades 2g-1 on the outer wall of the rotating rod 2g can continuously turn the materials in the conical barrel 5 and the materials at the bottom of the sand mixing cylinder 1 to the top during rotation, thereby accelerating the stirring efficiency.

[0030] Working principle: turn on the first transmission motor 4d and the second transmission motor 2e, pour the material from the opening at the upper end of the square box 3, and the two downwardly inclined guide plates 3a guide the material to the position between the two cylindrical grinding wheels 4b. The first transmission motor 4d drives the worm 4e to rotate, and then drives the two worm wheels 4c on both sides of the worm 4e to rotate toward each other, so the two worm wheels 4c drive the two cylindrical grinding wheels 4b to rotate toward each other through the rotating column 4a respectively. The two cylindrical grinding wheels 4b grind the material into fine particles, and the crushed material falls into the sand mixing cylinder 1 and the conical barrel 5. When the second transmission motor 2e drives the bevel gear 2e-1 to rotate, it can drive the bearing ring 2b to rotate, and when the bearing ring 2b rotates, it can drive the two at the bottom The first stirring plate 2f stirs the material in the sand mixing barrel 1.
