Answer 1

Metering is the Planter's core components, metering device of the seed planter have a direct impact on the work performance. Metering device test-bed for metering device performance testing of the major means of testing process 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 Experimental studies and provide a reliable basis for the design.
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 realize all kinds of mechanical seed for planting Uniformity of tests and other performance tests, with testing is accurate, reliable, intuitive and tablets from the source can be measured; seed-use of hydraulic lifting, a metering device test different heights, a compact structure, regulate simple, easy to operate , Responded rapidly and for the advantages of automatic control.

Key words: seed; hydraulic lifting system, control valve; design
