High-water-content livestock and poultry manure compost organic fertilizer spreading equipment and method

Abstract

The invention discloses high-water-content livestock and poultry manure compost organic fertilizer spreading equipment and a method. The equipment solves the problems that the fertilizer spreading machine in the prior art can be easily blocked; the throwing or the spreading is not uniform; the mechanical feeding cannot be realized. The efficient spreading of the high-water-content livestock and poultry manure compost is realized. The equipment is characterized by comprising a fertilizer box, a stirring mechanism and a throwing and spreading mechanism, wherein a main shaft which is driven by atransmission system to rotate is arranged inside the fertilizer box, and a material cabin cover plate with an adjustable opening angle is arranged on the top of the fertilizer box; the stirring mechanism comprises a stirring plate passing through the main shaft, and the extending-out length of the stirring plate on the main shaft can be adjusted adaptively according to the fertilizer quantity; andthe throwing and spreading mechanism comprises a plurality of groups of flexible material throwing mechanisms fixedly connected with the main shaft, and uniform throwing and spreading of the fertilizer can be realized by the material throwing mechanisms along with the rotation of the main shaft.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a high-moisture livestock and poultry manure composting and retting organic fertilizer spreading equipment and method. Background technique [0002] my country is a large animal husbandry country. Livestock and poultry farming produces 3.8 billion tons of livestock and poultry manure every year, but the effective treatment rate is less than 50%. Governments at all levels attach great importance to the control of livestock and poultry breeding pollution. For returning to the field, the advantage is that there is less odor and complete nutrients, but the content of nitrogen, phosphorus, and potassium is low. Compared with chemical fertilizers, the amount of application is large. Loading, transporting, and spreading require a lot of manpower and material resources. The labor intensity is high and the sanitary conditions are poor. . For compost fertilizers with high moisture cont...
