A combine harvester separates corn from the cob using several mechanical steps. First, the combine pulls down the stalks and pops the ears off. Gathering chains push the ears back, and an auger moves them inside. Next, a spinning rotor threshes the grain from the cob. Cleaning systems remove debris, and clean corn kernels go into the grain tank. These steps make the process quick and efficient. Modern harvesters, along with tractors and rice transplanters, help farmers work faster and collect more crops.
A combine harvester cuts corn stalks and takes off the ears. It removes kernels from cobs and cleans out debris. It stores the clean corn in a good way.
Changing the cutting height and drum speed helps save grain. Adjusting cleaning settings also keeps kernels safe.
New combines use strong materials and digital controls. These help threshing, cleaning, and handling grain get better results.
Doing regular checks and maintenance keeps the combine working well. This helps farmers get more good corn.
Combines work in many field conditions. They can work with tractors and grain dryers to make harvesting faster and better.
The harvesting starts when the corn combine harvester goes into the field. The corn header is at the front and helps cut the corn stalks. Snap rolls and rollers pull the stalks down. Sharp knives cut the stalks close to the ground. The reel pushes the cut corn toward the auger. The auger moves the stalks into the feeder house. This part is important in a corn combine harvester. You can change the cutting height to fit the field. This helps harvest corn well, even if the crop is uneven or has fallen over. Modern combine harvesters from FMWORLD Agricultural Machinery have strong blades and overload protection. These features help stop grain loss and keep things running smoothly, even when conditions are hard.
Tip: Picking the right cutting height and keeping knives sharp can help the combine work better and lower crop loss.
After cutting, the corn combine harvester picks up the ears with gathering chains and special rollers. Row dividers lift the stalks and guide them into a small space. Here, the ears get snapped off and separated from the stalks. Gathering chains move the ears into the combine for more steps. Strong parts and tough gathering chains help the harvester handle lots of corn without breaking down often. Shock absorbers under deck plates and big cross-auger tubes help stop ear damage and grain loss. The corn combine harvester is made to work in many field conditions, like when corn is down or tangled. This makes harvesting more dependable. FMWORLD Agricultural Machinery uses these advanced gathering systems in their corn combine harvesters. This helps them work well and waste less.
Farmers can trust FMWORLD’s corn combine harvester series to work well and last long. If you want better harvesting tools, you can look at tractors and grain dryers too. These can help your farm do even better. To find out more about FMWORLD’s machines, visit their product page.
The threshing drum is the main part of the corn combine harvester. It uses strong spinning to pull kernels off the cob. When corn ears go into the threshing area, the drum spins very fast. The drum has toothed or ribbed surfaces. These grip the ear with the concave shell. The drum pulls, rubs, and hits the ear. This breaks the kernels off the cob. The empty cob stays behind.
Operators can change how fast the drum spins. They also adjust the space between the drum and concave plates. If the drum spins too fast or the gap is too small, kernels can crack. If the drum spins too slow or the gap is too wide, some kernels stay on the cob. Modern corn combine harvesters use digital controls. These help set the best speed and gap. This keeps most kernels safe and removes them well.
Note: Flexible drum materials like EPDM rubber, nitrile rubber, and polyurethane rubber help stop kernels from breaking. These materials are softer and help keep grain quality high.
Material Type | Key Characteristics and Effects on Threshing Drum Performance |
|---|---|
EPDM Rubber | Flexible, reduces seed breakage, improves wear resistance, drum-shaped design optimizes threshing. |
Nitrile Rubber | Curved nail teeth, lower breakage rates than steel, flexible. |
Polyurethane Rubber | Similar benefits to nitrile, reduces breakage, flexible. |
Steel Nail Teeth | Rigid, higher impact force, more seed breakage, higher power consumption. |
Tests in fields show new concave systems in combine harvesters lose almost no kernels. Some systems keep nearly all kernels during threshing. This helps separate grain crops better and lowers grain loss by up to 30%. Farmers can harvest corn faster, about 3 to 4 km/h, and still get good quality.
After the threshing drum takes off the kernels, cleaning systems make sure only clean kernels go to the grain tank. Concaves under the drum catch falling kernels. These concaves can be adjusted for different crops and field types. They help separate kernels from stalks and cobs.
Kernels then move to sieves. There are two sieve levels, upper and lower. Sieves sort kernels from lighter debris like chaff and small plant bits. Operators change sieve openings to balance grain flow and remove debris. If settings are wrong, grain can be lost or damaged.
Air blowers are important for cleaning. The fan blows air up through the sieves. Light debris floats away. Heavy kernels fall down to be collected. Changing fan speed and sieve openings helps clean well and keeps kernel loss low.
Component | Role in Kernel Separation | Key Details and Adjustments |
|---|---|---|
Concaves | Separate kernels from crop stalks | Clearance adjusted for crop type and conditions; positioned beneath threshing drum. |
Sieves | Clean grain by separating from debris | Two levels; openings adjusted for grain flow and debris removal. |
Air Blowers | Move lighter debris away from grain | Airflow directed upward; fan speed and sieve openings balanced for cleaning. |
Modern corn combine harvesters keep grain loss below 1%. Automated systems set the best harvesting settings. This gives steady, high-quality results. Regular checks keep the threshing parts working well. Operators look at fan speed, rotor speed, transport vane settings, and gathering chain timing. These checks stop cracked kernels, missed ears, and too much grain loss.
Tip: Farmers should check and set the combine harvester before each harvest. Good care and setup help get more kernels and keep grain quality high.
FMWORLD Agricultural Machinery makes corn combine harvesters with advanced threshing and cleaning systems. These machines remove kernels well, lose little grain, and work in many field types. Farmers can also use FMWORLD’s tractors and grain dryers to make harvesting even better.
The cleaning system in a combine helps separate corn kernels from things farmers do not want. After threshing, kernels fall onto moving sieves. These sieves shake to sort kernels from chaff, husks, and small plant parts. The concave, top sieve, and bottom sieve each have a special job in cleaning the grain.
Sieve Layer | Description | Function in Cleaning Process |
|---|---|---|
Concave | Curved metal plate with slits or holes | Threshes grain, separates it from straw and husks, breaks straw into smaller pieces |
Top Sieve | Flat mesh or screen with smaller holes | Lets grain pass, keeps chaff and debris, separates leftover straw or husk pieces |
Bottom Sieve | Larger mesh or screen | Lets chaff and debris pass, keeps grain, removes leftover plant debris and chaff |
Air blowers help the sieves clean the kernels. The fan blows air up through the sieves. Light things like chaff and dust float away. Heavy corn kernels fall through the mesh and move forward. This makes sure the corn is cleaned well and farmers get only clean kernels.
Modern combine harvesters, like those from FMWORLD Agricultural Machinery, use sensors to watch for grain loss. These sensors help change sieve openings and fan speed. The cleaning system can work with different corn types and moisture levels. For example, when harvesting Zheng Dan 958 corn that is wet, the combine uses real-time feedback to keep grain loss low.
During cleaning, about 38.2% of debris is taken out of the corn. This high removal rate makes the cleaned corn kernels better. Farmers can count on the combine to work in many field conditions and with different corn types.
After cleaning, the combine puts the clean corn kernels in the grain tank. Operators check the tank to make sure only clean kernels are inside. The combine also chops and spreads leftover plant material on the field. This helps keep the soil healthy for the next crops.
The grain cleaning process works with other FMWORLD machines, like tractors and grain dryers, to help farmers work better. Farmers who use these machines get better results and more corn. FMWORLD Agricultural Machinery gives good solutions for every step of corn harvesting.
Tip: Keep the cleaning system in good shape with regular care. This helps the combine work well and collect high-quality corn.
A combine harvester has a big grain tank for storing corn. After cleaning, the corn kernels go into this tank. The tank can hold hundreds of bushels of corn. This keeps the harvested corn safe until it is unloaded. Operators watch how full the tank gets during harvest. When the tank is full, the combine uses an unloading auger. The auger is a long tube with a spiral blade inside. The blade moves the kernels to the unloading spout. The spout sends the corn into trucks or storage bins. Operators can move the spout to make unloading easier.
Combine Model | Grain Tank Capacity (bushels) | Grain Tank Capacity (liters) |
|---|---|---|
John Deere X9 1000 | 420 | 14,800 |
John Deere X9 1100 | 460 | 16,210 |
Modern combine harvesters, like those from FMWORLD Agricultural Machinery, have smart grain handling systems. These systems stop grain loss and keep the corn clean. Sensors and smart tools help operators watch the process. FMWORLD’s grain tank design makes unloading fast and easy. This helps farmers waste less and harvest more.
Tip: Operators should check the grain tank and unloading system before each harvest. Regular care helps stop blockages and keeps the combine working well.
After the combine takes out the corn kernels, it deals with leftover cobs and stalks. Straw walkers move this plant material to the back of the machine. Some combines chop up the cobs and stalks and spread them on the field. This puts nutrients back into the soil for the next crop. FMWORLD corn combine harvesters use special concave designs and rotor technology. These features help handle tough crops without clogging or hurting the grain.
Good residue handling cuts down on waste and keeps fields healthy. Advanced cleaning systems and yield sensors help operators change settings for each field. GPS and telematics give better control. This helps the combine collect more corn and leave less behind. FMWORLD also has tractors and grain dryers that work with their combine harvesters. These machines help with every step of harvesting.
