Modeling for performance and parameters of pneumatic seed-metering system of precision planter for rapeseed

2BFQ-6 precision planter for rapeseed can be used for sowing, fertilization, rotary tillage, stubbing and trenching. Pneumatic seed-metering system is the key component of this planter, and its working parameters and seeding performances directly affect the planter's operating performances that include the consistency of seeding quantity per row and the stability of the total seeding quantity of the planter.
