摘    要:沼液沼渣既是速效与迟效兼备、速效多于迟效的有机肥,又是防治病虫害的无污染、无残毒、无抗药性的"生物农药"。但由于没有沼液沼渣这种液态沼肥的机械化施肥技术和装备,无法施用于田间。同时,由于大中型沼气工程缺乏沼液沼渣的消纳途径,制约了沼气产业的发展。为此本文设计出一种液态沼肥暗灌施肥机械,该机械采用分配器对沼肥进行分配和防堵,一次进地能完成开沟、松土、施肥、起垄及镇压多道工序,减少了拖拉机及罐车进出耕地的次数。同时分析了分配器中沼液沼渣在管道中的流动性,发现其能集中沼液沼渣从总管到分管的瞬时流体能量。最后对施肥机进行了田间试验,结果表明所设计机具通过拖拉机配套牵引能进行沼肥运输、抽排工作。

关 键 词:沼液沼渣  暗灌施肥  施肥机械  分配器  施肥铲

Abstract:Biogas slurry residue has the characteristics of continuity and Large quantity. It has also a great difference with conventional liquid fertilizers. A fertilizer machinery used for biogas slurry dark field irrigation is designed based on the physical parameters of biogas slurry, and it can complete the operations of ditching, fertilizing, ridging, the suppression of process at one time. An distributor adopted by the fertilizer spreader can change continuous flow into intermittent flow and concentrate fluid energy, as a result the anti-blocking capability of the flow are improved to some extent. In addition, the maximum stress of fertilizing shovel applied the job force are in the allowable stress range. According to the calculations of the mechanical traction power for the entire fertilizer, DFH X904 tractor can meet the power demand of the fertilizing machinery when operating.
Keywords:Biogas slurry  Dark irrigation fertilization  Fertilizer applicator  Distributor  Applicator
