Farm Corn Combine Harvester

With the development of science and the continuous progress of society, the farm corn combine harvester has been widely used in the vast rural areas. Its advent has gradually replaced the traditional method of breaking corn by hand, greatly reducing the labor intensity of farmers and friends. Due to its precise structure, the farm corn combine harvester should be proficient in its operation methods during operation, so as to improve the operation efficiency and ensure the smooth completion of the autumn harvest. The operation methods of corn harvesters are also different under different environmental factors. Now the agricultural machinery experts will introduce them in detail:

1. Operation in windy weather

Do not drive the farm corn combine harvester in the windy weather to prevent the harvester from not working properly; the air inlet on the windward side of the grain cleaning mechanism should be reduced, and the air inlet on the leeward side should be increased in order to reduce the loss of the clearing belt. and improve the quality of clear grains.

2. Slope operation

Avoid cross-slope driving operations as much as possible; when harvesting uphill for a long distance, the rear of the sieve should be raised, a larger sieve hole should be selected, and the opening of the air inlet should be reduced to reduce grain loss; when harvesting uphill for a short distance, it is not necessary to Adjustment; the rear of the sieve should be lowered when harvesting long distances downhill.

3. Wet field operation

When the farm corn combine harvester operates in a low-lying area, the driving device of the harvester should be modified into a crawler or half crawler to harvest crops in time; when the depth of the mud feet is large, the width of the ground wheel of the unit should be increased to enhance the anti-skid ability and expand as much as possible. Grounding area to prevent the machine from sinking.

4. Operation of lodging crops

Appropriately reduce the forward speed of the unit; correctly select the harvesting direction of the unit, the forward direction of the unit should be opposite to the lodging direction of the crop (called reverse cutting), or 45° from the lodging crop. left and right angle (called For side cutting); properly adjust the reel forward and downward to ensure smooth reel and normal cutting.

5. Operation of low crops

Properly adjust and refit the header and reel. The height of the header should be adjusted to keep the cutting stubble no higher than 15 cm and the cutter will not eat soil. If the teeth are broken and damaged, adjust the reel downwards and backwards properly for normal harvesting; increase the forward speed of the unit to ensure normal threshing feed; carry out the harvesting operation in the direction of the sowing row, which can reduce the bow due to the increase in forward speed. The farm corn combine harvester that starts vibrates strongly, which can also reduce harvesting losses.

6. Operation of over-dried and over-ripe crops

Add canvas strips on the wooden turning wheel pressure plate of the farm corn combine harvester to increase the buffering effect of the reel in the reel and reduce the loss of grains; reduce the height of the reel so that the reel does not hit the head of the crop , to reduce grain drop; reduce the speed of the reel to reduce the number of hits on the cut crops.
