Panax notoginseng is a characteristic crops in Yunnan Province.It is known as Yunnan Agricultural bright pearl and 98% of Panax produced in Yunnan Province.In 2014 the province has reached more than 60 million mu of cultivated area.Panax international market demand for raw materials to 20% annual rate of rapid growth.Panax overall supply shortage of raw materials and production area and the overall increasing trend year by yearCompared with the booming industry of Panax,it production mechanization technology is backward.Through field research,the only way to achieve some mechanized tillage,and other production processes used in all the traditional manual, labor-intensive, low productivity and quality of work.It can not be standardized operations, is not conducive to the production of high quality Panax not meet require the development of modern agriculture, severely restricted the Panax industrialization.In this paper, for the above problems, the development and design of the machine precision seeder Panax key components.The main contents are as follows:1.Panax precision planter overall structural design.Notoginseng seed for the study.The use of electronic scales, the slope meter, the friction coefficient measuring instrument measuring the moisture content of different triaxial Panax seed size, friction angle, angle of repose physical characteristics.According to the technical requirements of Panax planting agronomic requirements and Panax Precision Drill. Panax precision planter overall structure design.2.Panax precision metering design and EDM.According to mechanical and physical properties of Panax and agricultural requirements, design of a type-hole Panax precision metering device and determine the parameters of the key components.According to the physical parameters of Panax seed measured using EDEM of Panax seed particles were modeled body.And with the establishment of the plant seed is a combination of particles were seeding process simulation analysis, the feasibility of the use of Panax Precision Drill hole type metering device.3.Experimental Study ofhole Seeder.To seed metering device operating speed, type the number of holes and hole diameter type size for the study of factors and sowing qualified index, index leak broadcast, a replay index and seed breakage rate response function Panax precision seed were three factors quadratic regression orthogonal rotation test.Get the optimal parameter combination metering device.Seeding in operating speed of 1.78km/h, several rows of round-shaped hole was 20.71, shaped hole diameter is 8.16mm, the highest qualified index, the lowest index leak sowing, sowing the lowest leakage rate index and the lowest breakage.4.Making planter.Other key components of the planter design and manufacture a prototype.According to the actual work situation, part of the structure can be further optimized. Through the analysis of the whole proposed improvements and optimization. The program can better meet thirty-seven sowing agronomic requirements, improve job performance planter. But the use of field experiments conducted to determine the effect remains.
