Understanding the Parts of a Rice Harvester
As a leading supplier of rice harvester components for Kubota and Yanmar, we understand the importance of understanding each component of these advanced agricultural machines. A thorough understanding of these components ensures optimal performance and longevity of the harvester. This article takes an in-depth look at the key components of a rice harvester, explaining their functions and importance.
1. Header
The header is the front part of a rice harvester and is essential for harvesting and collecting the crop. The design of the header may vary depending on the type of crop being harvested. For rice, the header typically has specialized blades and combs to efficiently cut and transport the stalks.
2. Reel
The reel is located above the header and helps guide the rice plants into the cutter bar. The speed and angle of the reel can be adjusted to accommodate different crop heights and densities, ensuring a smooth harvesting process.
3. Cutter Bar
The cutter bar is the main cutting mechanism of the harvester. Made of high-strength steel, the cutting bar cuts the rice stalks off at the root, allowing for efficient harvesting.
4. Auger
The auger is a spiral-shaped device that moves the cut rice stalks from the harvesting table to the feed chamber. This ensures a steady flow of material, prevents blockages and maintains harvesting efficiency.
5. Feed Chamber
The feed chamber is a channel connecting the harvesting table and the threshing mechanism. It transports the cut and collected rice stalks from the harvesting table to the threshing drum, maintaining a continuous and smooth flow of crops.
6. Threshing Drum/Roller
The threshing drum is one of the core components of a rice harvester. It separates rice grains from rice stalks by rotation and friction. The design and adjustment of the threshing drum directly affect the efficiency of rice grain separation and the integrity of rice grains.
7. Concave Plate
The concave plate works in conjunction with the threshing drum and plays a vital role in rice grain separation. By adjusting the gap between the concave plate and the drum, the operator can control the intensity of the threshing process, ensuring effective separation while minimizing rice grain damage.
8. Straw Cleaner
The straw cleaner further separates rice grains from straw. By shaking the straw, any remaining rice grains are removed and collected, ensuring maximum yield for the harvested crop.
9. Sieve and Cleaning Fan
The sieve and cleaning fan are responsible for removing the separated rice grains, removing husks and other debris. The cleaning fan blows away lighter impurities, leaving clean, high-quality rice grains.
10. Grain Bin
The grain bin stores the cleaned rice grains until they are ready to be unloaded. The grain bin is designed with a large capacity to minimize the frequency of grain unloading, thereby improving harvest efficiency. Sensors inside the grain bin monitor the grain level in real time.
11. Grain Unloading Auger
The grain unloading auger transfers grain from the grain bin to a truck or other storage facility. The spiral design of the auger ensures a fast and efficient grain unloading process, which is essential to maintaining workflow during harvesting.
12. Chopper and Spreader
The chopper and spreader are responsible for dealing with the remaining straw. They chop the straw into small pieces and spread them evenly on the field. This process helps the straw to decompose naturally, enriching the soil with organic matter.
13. Engine
The engine is the power source of the rice harvester. Modern rice harvesters are usually equipped with efficient, low-emission diesel engines that provide the necessary power for all harvesting operations.
14. Cab
The cab is where the operator controls the rice harvester. Modern cabs are equipped with a variety of comfort and safety features, including air conditioning, adjustable seats and advanced control panels, ensuring a comfortable and efficient working environment.
15. Hydraulic System
The hydraulic system controls various parts of the harvester, including the height adjustment of the header and the operation of the unloading auger. The efficiency and reliability of the hydraulic system are crucial to the overall performance of the harvester.
16. Tracks or Wheels
The tracks or wheels enable the harvester to move around the field. Tracks are usually used on wet or muddy terrain, while wheels are suitable for dry and hard ground. Both options ensure smooth movement and minimal soil compaction.
