Technical Field

[0001] The invention relates to the technical field of fertilizer mixing, in particular to a chelator for producing water-soluble fertilizers containing medium and trace elements. Background Art

[0002] Chelators are important chemicals used in the manufacture of chelated fertilizers, which can form stable chelates of metal ions, thereby improving the biological effectiveness of trace elements in fertilizers.

[0003] After searching, CN107694450A discloses a bidirectional stirring chelator for feed production, in which the bucket-shaped screening net is tilted and the crushing blade is arranged in parallel with the bucket-shaped screening net. However, the fertilizer accumulates at the lowest point of the bucket-shaped screening net, and the friction between the crushing blade and the crushing blade is relatively large.

The working process of the shaking mechanism includes: rotating motor 2 drives gear 2 25 to rotate, and when gear 25 is meshed with gear 1 24, gear 1 24 is driven to reverse. At this time, gear 25 is not meshed with the sawtooth, and gear 1 24 is meshed with the sawtooth, driving the movable plate 26 to move toward one side of the processing box 1, and gear 25 continues to rotate until it is meshed with the sawtooth, and at this time it is not meshed with gear 1 24, and the movable plate 26 moves away from the processing box 1.
