How To Properly Operate Agricultural Corn Combine Harvester

The farm corn combine harvester is very popular among farmers. It is multi-purpose, light and flexible! It solves people's hard work and the high efficiency of work avoids people's long exposure under the sun.

The following China coal experts introduce some precautions when using the farm corn combine harvester to protect your love machine.

1. The farm corn combine harvester should enter the ground at a low forward speed, but the engine must reach the normal operating speed before the harvest begins, so that the thresher runs at full speed. Self-propelled small jade to collect the machine before entering the ground. The working gear should be selected, and the stepless speed should be reduced to the minimum speed. When the forward speed needs to be increased, the speed can be achieved through the stepless speed, and the gear position should be avoided. . When receiving the ground, slowly raise the header to reduce the forward speed and turn, but the throttle should not be reduced to avoid blockage of the barrel.

2. Adjustment of farm corn combine harvester. The self-propelled corn harvester should adjust the threshing gap, the front and rear position and height of the reel, etc. according to the corn production star, the natural height and the lodging condition of the wet and dry in the harvesting process; and the piggyback harvester Such adjustments should be made before entering the ground.

3. Choose a large throttle operation. Farm corn combine harvester  should be operated with maximum efficiency. The throttle should always be operated at the time of harvesting. It is not allowed to reduce the forward speed by reducing the throttle. This will reduce the rolling speed, reduce the quality of work, and even block the drum.

  4. Selection of work gears. In the harvesting process of small corn harvesters, reasonable working gears should be selected according to factors such as the natural height of wheat yield, dryness and wetness.
5. Choice of operating width. Under normal circumstances, the combine harvester should be full of operations, but when the corn production is too high or the humidity is too high, when the minimum operation is still overloaded, the cutting width should be reduced, and when the cutting width is reduced to 80%. fulfil requirements.

6. Harvest of dry crops. When the corn has matured and passed the straight harvest period, it is easy to fall off during harvesting. The rotation speed of the reel should be properly lowered to prevent the loss of the grain loss caused by the reeling of the reel and reduce the speed of the operation. Harvest in the morning or evening.

7. Harvest of fallen crops. When the horizontally lodging corn is harvested, the reel can be appropriately lowered, but one should be harvested on the other side of the lodging direction to ensure thorough separation of the corn, smooth feeding, and reduction of corn kernel loss; The work should be reversed, but the reverse harvest requires empty return, which seriously reduces the efficiency of the work. When the crop lodging is not very serious, it should be harvested back and forth in both directions. When reversing the harvest, the reel should be adjusted to a forward tilt of 15%~30", and the reel should be lowered and backward; The plate teeth of the reel are adjusted to a position that is inclined backward by 15 to 30°, and the reel is raised and forward.

      8. Eyes on the six roads, listening to all directions. When the operator carries out the harvesting work, eyesight, ear work and handwork should be done. It is necessary to observe the instrument on the bridge, the flow of crops on the header, and the operation of each working part. Listen carefully to the sound of the engine's threshing drum and other working parts. If you see or hear an abnormal situation, you should stop it immediately. When the engine sound is dull, the threshing and rolling sound is abnormal, and the engine is black smoke, indicating that the threshing resistance in the drum is too large. The gap of the threshing drum should be adjusted appropriately, the forward speed should be lowered, or the main clutch should be stepped off immediately to stop. The knapsack corn harvester advances the power, then increases the throttle to perform threshing. After the sound is normal, lower the working gear position or reduce the cutting width for normal operation.
