Automatic sand screening type grinding material funnel

The invention relates to an automatic sand screening type grinding material funnel. The grinding material funnel comprises a funnel body and a screen which is horizontally arranged in an inner cavityof the funnel body, a motor is arranged below the center of the screen, a rotating shaft of the motor vertically penetrates through the center of the screen and is movably connected with the stirringrod, the stirring rod is arranged on the upper surface of the screen and rotates around the center of the screen under the driving of a rotating shaft of the motor, under the rotation of the stirringrod, the abrasive material with the particle size larger than that of the screen mesh can be pushed to prevent the large particles from blocking the screen, so that the sand screening efficiency can be improved. Compared with the prior art, the sand screening device has the beneficial effects that the stirring rod is arranged, so that the sand screening efficiency can be improved, the structure issimple, the operation is co
