Long-acting release control fertilizer granulation device with screening function for cultivation of onobrychis viciaefolia

Abstract

The invention discloses a long-acting release control fertilizer granulation device with a screening function for cultivation of onobrychis viciaefolia. The long-acting release control fertilizer granulation device comprises a cutting separating box, a first motor, a material distributing plate, a granulation hopper and a leaking plate; and a granulation storage box is mounted on the lower part ofthe cutting separating box, partition plates and fixing rods are mounted on the lower parts of stirring rods correspondingly, the material distributing plate is mounted on the lower part of a bearingplate, the granulation hopper is located in the middle of the top of the granulation storage box, a second motor is mounted on the bottom side in a fixing frame, the leaking plate is fixed to the outer side of the top of the fixing frame, and a filter plate is fixed to the bottom of a second accommodating cavity in a welded mode. According to the long-acting release control fertilizer granulationdevice with the screening function for cultivation of the onobrychis viciaefolia, the discharging speed can be adjusted, synchronous adjusting is conducted conveniently, complete conveying of materials can be ensured, fertilizer grains can be sieved, fine and small particles in fertilizer are screened out advantageously, and long-term controlled release using of the release control fertilizer isfacilitated.

Description

technical field [0001] The invention relates to the technical field of release-controlled fertilizer granulation, in particular to a long-acting release-controlled fertilizer granulation device with screening function for planting red bean grass. Background technique [0002] Red bean grass belongs to leguminous plants, and its root system has root nodules, which can fix nitrogen in the air. Generally, no fertilization is required, but scientific research shows that the application of certain nitrogen and phosphorus fertilizers is effective for the planting of red bean grass. It can effectively Increase the yield of red bean grass and improve the quality of red bean grass; [0003] The release-controlled fertilizer is based on coating on the outside to achieve the effect of controlling nutrient release. It can make the nutrients in the fertilizer release in the soil for two to three years, and always ensure that the red bean grass gets sufficient nutrients, which can effecti...
