Device for producing di-furfurylidene trialdehyde urea slow release fertilizer

The utility model provides a technical scheme of a device for producing a di-furfurylidene trialdehyde urea slow release fertilizer. The device comprises a sieving mechanism which comprises a stander, a sieve bracket, a cylindrical first-stage sieve, a cylindrical second-stage sieve and a driving motor, wherein the sieve bracket is fixedly arranged on the stander, the cylindrical first-stage sieve and the cylindrical second-stage sieve are arranged in the sieve bracket, and the driving motor is used for driving the sieve to rotate; a mechanical arm is arranged between a feeding hole of the first-stage sieve and the driving motor and comprises a first air pressure cylinder and a second air pressure cylinder; the first air pressure cylinder and a second air pressure cylinder are synchronously operated, and the stroke of the first air pressure cylinder is smaller than that of the second air pressure cylinder. The device can be utilized for separating particles of different sizes of the di-furfurylidene trialdehyde urea slow release fertilizer, so that the utilization efficiency of the di-furfurylidene trialdehyde urea slow release fertilizer is improved; meanwhile, the mechanical arm can be utilized for loading the bagged di-furfurylidene trialdehyde urea slow release fertilizer, so that a crane and the manpower resource are saved, and meanwhile, the loading speed is increased; the device has strong practical significance.
