The utility model discloses an improved automatic packing machine for producing powdery humic acid fertilizer. The improved automatic packing machine comprises a machine body, a conveying belt and a material bin are arranged on the machine body, the material bin is connected with a discharging outlet through two feeding screw rods, a carrying mechanism is arranged at the discharging outlet, a vibration pump is arranged above the carrying mechanism, and a vibration bar is arranged below the carrying mechanism. The improved automatic packing machine has the advantages that the phenomenon that gas is carried in the discharging process is avoided according to the characteristic of small bulk density of the powdery humic acid fertilizer, and the packing requirement of powdery materials is met. |
