The air-suction precision seed-metering device is prone to the instability of seed adsorption state, which arises from blockage suction hole and leads uneven seeding. This paper analyzed determined key structural parameters plate, then established an mechanics model during migration process designed structure with aim improving uniformity high-speed direct seeding vegetables. Furthermore, we us...

In order to meet the requirements of rice field precision direct seeding in rows and hills, a spiral grooved seed metering device for hills is designed. The Matlab software used study movement trajectory buds groove during process. Based on quadratic regression-orthogonal rotation combination design, taking working speed wheel, length helix angle as test factors, well qualified rate hill diamet...

The seed filling of a seed-metering device is critical process in sugarcane cultivation operations. To analyze the contact between billets, related mechanical components, and law billets movement device, simulation seed-filling based on EDEM was proposed, geometric model particle model, were established by software. physical experimental results angle repose compared. showed that relative error...

A negative pressure chamber rotary precision seed metering device was designed to achieve the buckwheat sowing goal, solving problems of traditional poor sealing and air suction high power consumption. The planting plate fixedly connected with shell forming a chamber, which rotates around an axis. suitable for designed. Single factor test response surface were carried out on device. Results sho...

in this study an innovatively designed tractor-mounted, ground-wheel driven, triple unit, row crop precision planter capable of planting three rows of garlic (allium sativum l.) cloves on each raised bed was designed, fabricated and tested. the major components of this planter include; chassis and transport wheels, lister-bedder unit, seed hopper, seed metering drum, sweeper, knocker, seed tube...

The issues of research work seed metering devices by the method discrete elements (DEM) are considered. A 3d-model developed intended for use with an unmanned aerial vehicle is presented. Its main design parameters and characteristics virtual stand used in study described. brief description physical model interaction seeds working given. As a result study, data were obtained on capacity hopper ...
