Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fertilizer production, in particular to feeding, conveying and stirring equipment for blending fertilizers. Background Art
[0002] The mixing and stirring equipment used in the production of blended fertilizers generally includes a conveying and feeding device and a stirring device. The stirring device is typically located at a relatively high height, requiring workers to transport the fertilizer raw materials to a higher location before feeding them into the stirring device's feed hopper. Existing fertilizer feeding and conveying devices often lack auxiliary feeding and discharging mechanisms, relying instead on gravity for direct feeding and discharging. This often results in excessively concentrated fertilizer feeding onto the conveyor belt and excessively dispersed discharging during discharging. Conventional fertilizer mixing and stirring devices typically incorporate a stirring shaft and stirring blade assembly directly within the housing. This often results in insufficient stirring efficiency and prolonged stirring times, increasing power consumption and production costs. Utility Model Content

After reaching the upper end of the conveyor belt, the fertilizer gradually slides down under the action of gravity.

The fertilizer slides into the inclined discharge chute of the auxiliary discharging mechanism, is blocked by the inclined bottom plate and vertical material-blocking plate, and is finally sent to the subsequent mixing device. Fertilizer from the inclined discharge chute enters the horizontal mixing chamber through the feed port at the top of the central cylindrical section.
