| Health sugarcane seedlings tillering rate,good perennial performance,a high sugar,planting seed quantity can save about 60%,can greatly improve the quality of sugar cane,at present,it is rapidly evolving.But its cultivation agronomic requirements:ditching wider groove(width of about 30-40 cm),planting row seed single stem bud,placed every 1 m distance of about 6 to 8 single bud seed,stem length of about 6 cm,or some species of sugarcane distance 40cm(length 20-30cm),seed quantity is only 2000 kg/hm2,traditional sugar cane seed furrow width of about 25 cm per 40 cm from the vertical section 1 sugarcane species(length 20-30cm),seed quantity 12000 kg/hm,if the use of human and animal cropping patterns,work efficiency is relatively low,labor-intensive,high operating costs.At present,the market has not yet supporting the planting machine,but also seriously affect the health of sugarcane seedlings of large-scale application.Therefore,the development of suitable mechanized sugarcane planting healthy seed technology is more urgent.By analyzing the combined basis of sugar cane and sugar cane machinery health status of seedlings planted on the current agronomic,we developed a single bud stage cane healthy seedling planting machine,wide and narrow row planting patterns,suitable for sugar cane cultivation has cut health segment seedlings sugarcane segment,to complete a row to open deep wide ditch,fertilization,artificial cane segment in an orderly manner under seeding,disc casing,such as planting operation step by theoretical calculation,prototype and field test trial means,mainly the following conclusions:1.Design and development of a healthy type 2CZX-2 seedling planting machine,mainly by seeding mechanism,opener,fertilization mechanism,casing and other components.?Seeding with a seeding mechanism designed by pasting the rubber band composed of sugarcane species protection groove,to achieve an orderly manner under artificial sugarcane species separated analysis reveals that the normal working conditions and structural parameters Metering institutions main working parts mainly:when sugarcane seed tank capacity is 0.87m3,seeding with a selection of plastic canvas flat belts,rubber truncheon double arrangement,the traveling speed of the prototype takes 1.25m/s,with a linear velocity of seeding in line with the requirements for the cultivation of 0.4m/s.?Design types of fat isolated opener wide open deep ditch,ditch to achieve a double pendulum seed and fertilizer.Calculation of theoretical and empirical analysis to determine the structural parameters of the main opener opener buried corner,the front opening angle,camber side retaining plate,width 40cm.?Fertilization mechanism using spiral of fertilizer,compact,two-way row fertilizer.When combined with healthy seedlings planted applied more fertilizer,fertilizer tank separated into three cells,mix by mixing discharged by a screw.Through theoretical analysis and calculation,to determine the fertilizer tank volume 470L,fertilizer 0.034kg/m.?The design of the casing main disc means,a transverse frame,a disk holder,adjusting devices and other components,innovative design angle position adjustable multiple disc structure,to achieve cane shallow overburden Disc diameter 30cm,thickness of 2mm,to achieve the structure simple and reliable earth.2.Prototype field trial performance test:an average diameter of sugarcane seedlings 27.27mm,sugarcane segment average length of 63.73mm,trenching average depth of 31.0cm,stability coefficient reached 87.1%,seed and fertilizer pitch 4.0cm,the leakage rate species 5%,after falling sugarcane seed seed seed trench distance of 12.6cm,equipment work productivity of 0.61 hm2/h,fuel consumption of 19.7 kg/hm2,can basically meet the requirements of a healthy seedling planting techniques.How to achieve precision seeding will be the focus of future improvements. |
