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,...
To solve the problem of straw cleaning and drip irrigation belt restoration for no-till seeding in areas, a staggered device was developed seeding, which is mainly composed front two-sided tine discs group, laying mechanism, middle single inner rear outer group. Different disc groups are set longitudinal, transverse, radial directions to move throw on surface strip. The critical parameters were designed calculated, radius determined be 160 mm, number teeth 12, theoretical working width...
The geometric characteristics, physical parameters and contact of coated cotton seeds were obtained through theoretical analysis experimental measurements. A discrete element model reflecting the intrinsic was established, calibrated using Discrete Element Method (DEM), significant factors affecting stacking angle screened Plackett-Burman method. optimal ranges determined by steepest ascent method, a second-order regression established central composite design. following values for seeds:...
To solve the current problems of poor seeding stability and complex maintenance maize seed-metering devices, a clamp-holding precision maize-seed-metering device is designed. The structure working principle are described, optimum state seed clamping analyzed, range each area determined. profile structural parameters limit guide plate designed by analyzing laws motion seed-picking block. A mechanical model seeds under critical in established. influence device's rotational speed force block on...
