The metering device is the central part of seeder discharging granular fertilizers or seeds from hopper to colter passing through tube. Depending on design, batches particles are discharged evenly. This research analyzes existing devices, and a new pin-roller recommended discharge evenly high doses wheat at low rotation speeds. objective was adapt precision agriculture so that little electric m...

The planter plate is the most important component of pneumatic hill-drop seed metering system for rapeseed. structural parameters are primary determinants rape planting. key and operational parameters, such as layout suction hole, its diameter, shape, were determined through theoretical analysis. Fluent used to simulate flow field various types holes, effect hole shape on change in chamber shel...

A rationale is offered and methodology illustrated for integrating the fundamental steps involved in the collection and processing of blood for laboratory evaluation. The approach taken in the development of these concepts and components greatly extends the possibilities of laboratory systems integration without upsetting established modalities. A prototype design of the integrated blood-collec...

Sandy water sources are widely distributed and important for agricultural development. However, no explicit result has been achieved in the research of accuracy reliability pipeline metering devices as well flow rate measurement objects (water or water–sand) different process pipelines conveying muddy water. In this study, seven kinds sediment concentration gradients, C0–C6 (0.2–7.19%), three v...

As a promising and convenient numerical calculation approach, the discrete element method (DEM) has been increasingly adopted in research of agricultural machinery. DEM is capable monitoring recording dynamic mechanical behavior materials operational process machinery, from both macro-perspective micro-perspective; which tremendous help for design optimization machines their components. This pa...

A metering scheme is a method by which an audit agency is able to measure the interaction between servers and clients during a certain number of time frames. Naor and Pinkas 21] proposed metering schemes where any server is able to compute a proof, i.e., a value to be shown to the audit agency at the end of each time frame, if and only if it has been visited by a number of clients larger than o...

Metering technology is one of the core technologies of the smart power grid. The overall metering solution and related products have a wide market space in the whole process of power production, which bring new opportunities for power distribution development from automation to intelligentialize, and provide technical supports for the power metering system platform. Because of the importance of...
