چکیده
In order to further improve the seeding performance of maize seed-metering device, a pressure-holding precision device for was designed. The is made up several seed rowing modules, which effectively solves problems inconvenient disassembly and complex maintenance current device. working principle introduced, mechanical kinematic analysis seeds during operation carried out. orthogonal test out with installation diameter device's guide plate, torsion spring's wire rotational speed as factors, single-seeding rate, missed-seeding rate multiple-seeding indexes, relationship between different factors on obtained. By optimizing model, best obtained when plate 92.32 mm, spring 1.59 0.41 r/s. At this time, single-seed 93.08%, 3%, 3.9%, met requirements industry standard.

Design and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton
This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...
متن کاملSimulation Design of the Spiral Groove Precision Seed-Metering Device for Small Grains
At present, most of small grain crops such as millet and forage seeds are sown by external force feed in mainland China, which has some problems of wasting seeds, uneven seed distribution and so on. Therefore, it is needed to design a precise feed device for small grain corps. The author’s of this paper established a three-dimensional model to design the spiral groove precision seed-metering de...
