Sowing machinery is an important component of agricultural machinery, the pros and cons of direct impact on the planter to the agricultural labor productivity, crop yield and the cost of agricultural products, development of high-quality planting machinery is the urgent requirement of modern agriculture. Metering device research and development test bed planter is used by the major means of quickly produce a new generation of high-performance is essential for test equipment planter. Application metering device test bed can be exempted from the restrictions in field conditions, to artificially create various conditions, the metering device and the main parameters of the performance of an in-depth and extensive pilot study and provide a reliable basis for the test bed used roller conveyor belt-driven precision seamless manner, the metering device stepless speed regulation, auto-injector scratch based on the kind of image processing and analysis of the tablets from the detection system can achieve precision seeder, and the planting of cereals Drilling Monomer, seed-sowing uniformity of the testing and other operating performance tests, with testing is accurate, reliable, intuitive and tablets from the source can be measured; using seed-column connection with the take-off and landing part of the body movements and Luo Shuan Metering device to achieve 11 ° tilt adjustment and height adjustment to simulate the movements slope planting performance test; PLC by a computer system with the implementing agencies in real-time control and achieve the performance of the whole-controlled words: sowing machinery; metering device test bed, Performance, real-time control;
