In order to improve the single-grain seeding rate of pneumatic single seed metering device, an airflow cleaning device was designed in combination with positive pressure airflow. The influence position mechanism on effect is theoretically analyzed and a flow field simulation test analysis different nozzle structures carried out by using Fluent software (ANSYS, Inc., Canonsburg, PA, USA). result...

Mechanized sugarcane seeding is one of the effective technical measures for improving uniformity and operation efficiency. However, imperfection supporting equipment limits promotion application this technology. As there are some problems in domestic planting machines currently, such as large auxiliary labor, high labor intensity, low uniformity, amount seeds, a disc-type single-bud seed meteri...

in this study, using sound created by wheat grain passing through a pipe, wheat flow rate was measured. the developed device consists of a hopper, metering device, sound sensor, delivery tube, dc motor and power supply. several wheat mass flow rates were tested and the sound signal created by the passage of the grain through the discharge tube was measured and transferred to a computer using da...

Abstract. The crop producers who cannot buy a second planter due to its cost, have been seeking take advantage of the with roller-type metering device in dry bean sowing. While seemingly adequate for sowing, if roller structural properties and operating parameters suitable seed dimensions are not used, it can cause an increase damage ratio. In this text, mission was undertaken determine damaged...

In order to improve the large-scale production efficiency of corn and realize intellectualization automation seed metering technology, it is necessary combine modern computer technology with intelligent algorithm establish a feasible model suitable for device. this paper, watershed EDEM (EM Solutions EDEM) are used an efficient particle recognition model. Watershed image matching recognition, s...

Producing robust and scalable fluid metering in a microfluidic device is a challenging problem. We developed a scheme for metering fluids on the picoliter scale that is scalable to highly integrated parallel architectures and is independent of the properties of the working fluid. We demonstrated the power of this method by fabricating and testing a microfluidic chip for rapid screening of prote...

We have developed the first hardware and software (intellectual property) metering scheme that enables reliable low overhead proofs for the number of manufactured parts and copied programs. The key idea is to make each design slightly different during postprocessing phase. Therefore, if two identical hardware/software designs or a design that is not reported by the foundry are detected, the des...

A concept design of a carrot seeder, filed for patent application, was successfully developed in this study. Farmers were visited and interviewed the data regarding their existing practices planting carrots, corresponding tools equipment requirements such as hill spacing, row spacing plant bed size gathered. These used input preparation simulation seeder with aid Solidworks software.
 The ...
