A combine harvesteris a modern large-scale agricultural machinery that combines harvesting, threshing, separation, and cleaning of multiple grains in one machine, greatly improving agricultural harvesting efficiency

The main functions of a combine harvester

1. Harvesting

Crop cutting: Mature grain crops (such as wheat, rice, corn, etc.) are cut from the field and collected into the machine through the front-end header.

2. Threshing

Separate the seeds from the plant: After the crop enters the machine, it is shaken out of the straw and ear shell by a threshing device (such as a threshing drum, a slit plate, etc.).

3. Separating&Cleaning

Separating debris from grains: After threshing, weeds, stems, shells, and other materials are mixed, and the machine uses a cleaning system (sieve, fan, etc.) to separate the grains from different weights of debris.

4. Collection and storage

Storing grains: The cleaned grains are transported to the large grain bin inside the machine; When the grain tank is full, it can be unloaded onto the truck for further transportation

Main advantages of combine harvester

✔  Significantly improve homework efficiency

A single machine can complete multiple steps such as cutting, threshing, and cleaning, saving a lot of time compared to manual or traditional mechanical methods.

✔  Save labor

Only one or a few operators are needed to complete large-scale harvesting, reducing labor costs.

✔  Reduce food losses

Mechanized and continuous operations reduce food losses caused by manual operations or multiple transfers.

✔  Improve the quality of grain

The cleaning system can remove more impurities, making the harvested grain cleaner and of better quality

The combine harvester mainly includes:

Header: Cut crops and transport them into the machine.

Feeding device and thresher: feed crops into and loosen seeds.

Cleaning system: Remove stems and small debris, leaving clean grains.

Grain tank and unloading device: storing and loading harvested grains
