Rice is a staple food for Indonesian people, but the loss of crop yields still relatively high. The can be reduced by making improvements to application technology. Technological innovation in agriculture increase agricultural productivity. process accepting technological defined as adoption. Farmer’s adoption technology determined characteristic innovation, including relative advantage, compat...

The purpose of this study is to evaluate the performance a robot combine harvester by comparing Centimeter Level Augmentation Service (CLAS) and Multi-Global Navigation Satellite System (GNSS) Advanced Demonstration tool for Orbit Clock Analysis (MADOCA) from Quasi-Zenith (QZSS) using Real Time Kinematic (RTK) positioning technique as reference. first section evaluates availability precision un...

Aiming at the problems of poor applicability traditional header height detection mechanism, stability and large lag automatic control system combine harvesters, an harvester was designed, which mainly included profiling controller, proportional valve, manual operation handle display module. The mechanism composed angle sensor, plate, torsion spring other structures. key structural parameters we...

colza (canola) is a crop with high rate of grain loss during harvesting. at harvest, semi-dried grains of canola’s pods are either opened or dropped due to mechanical impacts. therefore, lots of grains drop before entering combine head. another obstacle to successful harvest of canola is that ripe grain's pods are twisted together. this results in heavy grain loss at dividers of combine pi...

Cleaning loss is an important parameter to judge the performance of a corn combine harvester. At present, there exists phenomenon that cleaning rate detection devices have long signal processing time and low recognition accuracy. To solve this problem, based on principle impacting piezoelectric effect, signals kernels impurities are analyzed by means frequency spectrum method obtain characteris...

In order to improve the operational performance of self-developed 4HLB-4 half-feed four-row peanut combine harvester, single-factor and multifactor field tests were conducted on key parameters affecting quality harvesting. The response surface methodology was used study effects forward speed, clamping height, picking roller rotational cleaning sieve vibrational frequency loss rate impurity rate...
