The double vertical stranded dragon fertilizer spreader is a new type of agricultural machinery that uses a tractor to throw livestock manure, fermented organic fertilizer, and manure (including compost) back to the field. It is mainly composed of traction frame, frame welding, fertilizer box, hydraulic system, transmission system, fertilizer delivery device, fertilizer spreading system, ground wheel mechanism and other systems. The fertilizer feeding system of the machine is driven by the tractor power output shaft to drive the stranding dragon to disperse the fertilizer through the triple gear box, and the double fertilizer spreading plate cooperates with the stranding dragon to fully throw out the fertilizer. Product advantages 1. Stranded dragon blades are distributed in steps, crushing more evenly, good adaptability to fertilizer, and convenient blade replacement. 2. Adopt Adil axle, good braking performance, automatic steering system is sensitive, safe and durable. 3. Guardrail panels can be added on both sides of the fertilizer box to expand the capacity of the box, and the loading capacity can be increased by at least 15% or more. 4. The fertilizer gate can effectively control the amount of fertilizer produced, and the hydraulic lifting is more convenient. Vertical twisted dragon crushing blade adopts spring manganese steel, high hardness, good wear resistance, corrosion resistance, long service life, strong crushing capacity, can effectively break the thrown organic materials, effectively throw livestock manure into the field, and spread fine and evenly. It can improve the effectiveness of soil nutrients, improve soil structure, improve soil fertility and water retention capacity, reduce environmental pollution of manure, and play an important role in mechanization of agricultural and animal husbandry livestock manure return to fields.
