The working principle of a rice harvester

2024-05-09

The divider separates the uncut rice from the cut rice. The threshing wheel guides the uncut rice towards the cutting mechanism, which cuts and places the rice onto the harvester. The stirring dragon on the harvester feeds the rice toward the middle of the conveyor belt, where retractable fingers push the rice into the feeding conveyor, which transports the rice to the threshing mechanism for separating the grain. The grain is then sent to the cleaning mechanism for further processing and is eventually carried to the grain bin. The stalks are discharged outside the machine.

To maintain optimal performance, each component of the rice harvester must operate at the rated speed. The engine should run at medium to full throttle to prevent the cutting platform, stirring dragon, conveyor, threshing cylinder, and grain discharge dragon from clogging. During operation, it is important to maintain a stable throttle speed, and after reaching the end of the field, the engine should continue to run for about 20 seconds at medium to full throttle to complete grain separation, cleaning, and straw discharge before reducing the throttle speed.

The height of the stubble not only affects the quality and efficiency of the harvester but also has an impact on the quality of the subsequent tillage. A high stubble is more conducive to improving production efficiency and reducing the workload of the harvester's components but is not beneficial for subsequent tillage. A low stubble can cause soil to get stuck on the cutting blades, leading to damage. It also reduces production efficiency and overloads the rice harvester's parts. When harvesting fallen rice, the stubble should be lower. The cutting platform's height can be adjusted to regulate the stubble height.

Working at maximum cutting width can increase efficiency. However, the driver should adjust the cutting width based on the yield, field conditions, and other factors to ensure continuous operation. In general, it is advisable to work at full cutting width.

Choosing the correct operating speed directly affects the efficiency and quality of the rice harvester. The harvester can travel in six forward gears and two reverse gears. Four gears are typically used when working in the field: three forward gears and one reverse gear. The gear should be selected based on the rice yield.
