Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite fertilizer feeding, and particularly relates to a composite fertilizer anti-caking feeding device and method. BACKGROUND

[0002] Composite fertilizer is prone to moisture absorption and dampness, which leads to the caking of composite fertilizer.

The front lower end and the rear lower end of the large concave cover plate are connected with the rack. The application puts the composite fertilizer on the large circulating belt in turn. The third rotating shaft can drive the sleeve to rotate. The sleeve drives the lifting rod and the contact wheel to rotate. The contact wheel can push the movable plate upward. The movable plate drives the D-shaped rod to move up and down through the rectangular connecting plate. The D-shaped rod drives the large circulating belt to move up and down. The composite fertilizer can be shaken up and down. The arc-shaped turning plate can turn the composite fertilizer, so as to prevent the particles of the composite fertilizer from caking in the conveying process. However, the applicant finds that the large circulating belt moves up and down to drive the composite fertilizer to shake up and down, which easily causes the composite fertilizer to accumulate together, and increases the probability of caking of the composite fertilizer.
