The invention relates to a mixing device for agricultural pesticide production, which comprises a mixing device body, a rack, a fan, an air inlet pipe, a plurality of air inlet nozzles, an air outlet pipe and a plurality of air outlet nozzles. The mixing device body is arranged on the rack; the fan is arranged on a cross beam in the middle of the rack; the air inlet pipe is of a bending structure formed by a horizontal part and a vertical part; a pipe orifice of the horizontal part of the air inlet pipe is connected with an air outlet of the fan; a plurality of air inlet nozzles with one ends communicating with an inner cavity of the air inlet pipe are arranged on the vertical part of the air inlet pipe; the other ends of the air inlet nozzles communicate with an inner cavity of the mixing device body; a plurality of air outlet nozzles symmetrical to the air inlet nozzles are arranged on the mixing device body; one ends of the air outlet nozzles communicate with the inner cavity of the mixing device body; the other ends of the air outlet nozzles are arranged on the air outlet pipe and communicate with an inner cavity of the air outlet pipe; and air discharged through the fan sequentially passes through the air inlet pipe and the air inlet nozzles so as to enter the mixing device body, removes moisture in a pesticide mixed material, and is discharged after sequentially passing through the air outlet nozzles and the air outlet pipe. By utilizing the mixing device, pesticide raw materials can be mixed more uniformly, and the work efficiency is improved.
