Organic fertilizer screening plant

Abstract

The invention discloses an organic fertilizer screening plant which comprises a feeding hopper, a separating mechanism, a receiving hopper, a feeding pipe, a discharging hopper and a conveying mechanism which are sequentially connected. The separating mechanism comprises a separating screen, a motor and a collecting chamber, the separating screen is in a bucket shape, a center shaft is connected to the middle portion of the separating screen, the motor and the center shaft are coaxially connected, and a cam is rotationally connected to the center shaft; the separating screen comprises an upper screen plate and a lower screen plate which are fixedly connected, screen holes in the upper screen plate are gradually decreased from the center to the edge; small screen holes, middle screen holes and large screen holes are sequentially formed in the lower screen plate from the center to the edge, and a small cavity, a middle cavity and a large cavity are arranged in the collecting chamber; and the conveying mechanism comprises an annular groove, a ring rotationally connected with the annular groove and blades arranged in an inclined manner in the axial direction of the feeding pipe, and the blades are fixed to the ring. Compared with the prior art, the organic fertilizer screening plant can rapidly screen organic fertilizer according to the organic fertilizer particle size, and meanwhile, the screened organic fertilizer can be prevented from generating blockage in the feeding pipe.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer production, and specifically discloses an organic fertilizer screening device. Background technique [0002] Organic fertilizers are rich in organic matter and nutrients needed for crop growth. They can not only provide the nutrients needed for crop growth, improve the soil, but also improve crop quality, increase crop yield, promote high and stable crop yields, and maintain soil fertility; at the same time, organic fertilizers It can improve the utilization rate of fertilizers and reduce production costs. Fully rational use of organic fertilizers can increase crop yields, improve soil fertility, improve the quality of agricultural products, and increase the effectiveness of soil nutrients. [0003] In the production of organic fertilizers, for organic fertilizers produced using livestock and poultry manure as raw materials, the main production processes are batching, adding bacterial a...
