The invention discloses a pet feed mixing device. The pet feed mixing device comprises a motor, a material mixing
barrel, a
circular cone table and a spindle, wherein a feeding inlet is formed in thetop surface of the material mixing
barrel and the center of the top surface of the material mixing
barrel is rotationally sealed with the spindle, the spindle is hollow and cylinders are arranged at the upper side part of the spindle, and a cross rod is in
ball joint with the middle part of the spindle; a plurality of stirring rods are connected onto the cross rod on both sides of the spindle, a first
magnet and a gravity block are respectively arranged at the end parts of the stirring rods on both sides,
piston rods are hinged to the cross rod and connected with pistons in the cylinders, first guide pipes are arranged at the upper ends of the cylinders, and second guide pipes which extend into a cavity inside the spindle are arranged at the lower ends of the cylinders; the
circular cone table is fixed at the bottom of the material mixing barrel, a plurality of protrusions are arranged on the
circular cone table, second magnets are mounted on the protrusions on one side, the
magnetic poles of the second magnets are the same as those of adjacent ends of first magnets, the second guide pipes extend out of the bottom of the spindle, and tee pipes are arranged inside the circular conetable, and rotationally connected with the second guide pipes, wherein two bifurcated pipes of the tee pipes respectively protrude from an inclined surface of the circular cone table. By adopting thedevice disclosed by the invention, granules and powdered pet feed can be uniformly mixed.
