Shaking type slow-release fertilizer coating device

Abstract

The invention provides a shaking type slow-release fertilizer coating device which is positioned in slow-release fertilizer production equipment which faces downwards gradually and comprises lifting blocks, a shaking disc, a granule conveying slipway and a material spraying structure, wherein the shaking disc is connected with the inner wall of the production equipment through the lifting blocks in a sliding manner; an electronic push rod A is arranged below four lifting blocks in cross positions; the lifting blocks make reciprocation movement along the inner wall of the production equipment under the action of the electronic push rod A to drive the shaking disc to shake continuously in the equipment; the granule conveying slipway and the material spraying structure are arranged above theshaking disc; a fertilizer core is dropped into the shaking disc from the granule conveying slipway; materials are coated in the shaking disc in shaking. By using a cradle type coating method, the fertilizer core is irregularly rolled in the shaking disc, the coating time can be prolonged, the fertilizer core can be completely coated by a coating layer, the coating failure rate is reduced, and fertilizer effects can be improved.

Description

technical field [0001] The invention relates to the field of fertilizer processing, in particular to a shaking-type slow-release fertilizer coating device. Background technique [0002] In the current stage of crop cultivation, the use of water-retaining slow-release fertilizers is becoming more and more extensive. Slow-release fertilizers use coating technology to coat the surface of fertilizer particles with a layer of hydrophobic substances, so that the nutrients in the particles slowly pass through the coating layer. release, to achieve the effect of long-term support of crop nutrition. Among the existing organic fertilizer production technologies, tower-type production equipment is gradually favored due to its small footprint and good sealing, while the coating method in tower-type production equipment is mainly There are two types of disc type and slope type. The disc type is coated by the rotation of the disc, and the slope type is coated by the fertilizer core rollin...

[0002] In the current stage of crop cultivation, the use of water-retaining slow-release fertilizers is becoming more and more extensive. Slow-release fertilizers use coating technology to coat the surface of fertilizer particles with a layer of hydrophobic substances, so that the nutrients in the particles slowly pass through the coating layer. release, to achieve the effect of long-term support of crop nutrition. Among the existing organic fertilizer production technologies, tower-type production equipment is gradually favored due to its small footprint and good sealing, while the coating method in tower-type production equipment is mainly There are two types of disc type and slope type. The disc type is coated by the rotation of the disc, and the slope type is coated by the fertilizer core rolling over the slope. Both methods require the rolling of the fertilizer core to reach a certain speed, so that the fertilizer core It can be rolled to the next process, it is difficult to ensure the completeness and uniformity of the coating, and once the coating is incomplete, the fertilizer granules will lose the slow-release effect
