In harvesting and cross-regional operations of combine harvesters, due to unreasonable natural conditions in various regions, various conditions may be encountered during operations. As the driver and the driver must perform joint harvesting according to different difficulties. Machines regulate the operation of rice and wheat, as well as the maintenance and adjustment of the units, so that the machines can function under normal operating conditions. The drivers and operators (as an example of the Yanmar “Popular†machine that is currently used more often) should know and have the following key points: (1) Preparation before harvesting: Engine inspection - Oil, cooling water, and radiator cleaning, blowing from the inside when cleaning. Inspection and refueling are carried out on each conveyor chain of the oil-recovery section of each operation section of the machine, check the pressure of the grass spring (shaft) and the feed chain, and check the refueling of the secondary draft guide bar. Before confirming the daily harvesting operations, confirm the adjustment position of the combine harvester before confirming the correctness of each part of the machine before harvesting. After entering Tiantou, the fields were hand-harvested for efficient operations. Remove foreign material around the field block for a week, such as wooden bamboo, stone, iron wire, canned box and so on. (2) Operation method and steps: 1After the operator confirms the safety of the surroundings, start the engine and press the automatic threshing depth switch. After the horn is sounded, increase the engine speed and slowly close the threshing clutch. Then close the cutting clutch and lower the height of the header, usually about 5-15cm away from the lowest position of the header splitter. When harvesting near Tianshao, the driver should pay more attention to it and pay attention to finding problems and correct operations in a timely manner. Due to the time-consuming task of cross-regional operations, there is no manual harvest operation at Tianjiao, and the operator must also perform the operation according to the instructions. The turning of the combine harvester operation also needs to be performed according to the specifications. 2 encounter special conditions of the harvest operation method. Refers to more water, more weeds, and more immature crops: Slow down the harvest rate and deepen the feed depth appropriately. If there are crops that are easily transported out and fall off, it is necessary to reduce the position of the abutment and slow down the harvesting speed. When the fields are dry, dusty, and weeds are large, 3 When wet weather is encountered during continuous rainy weather, place the "auxiliary speed change: handle in a low speed position. Try to increase the hand-cut area at the field corner of the field. The reversing distance should also be increased. When going straight forward or backward, do not operate the main machine drastically. Joysticks: Increase the number of steering and straight-line harvests to avoid sharp turns and minimize the load on the combine.First harvest the harder part of the ground.The softer part of the ground should be harvested in a single direction to avoid multiple turns in soft ground. 4 encountered lodging operations. Check that the front ends of several dividers are at the same height; for complete lodging of crops, lower the front end of the dividers, and the auxiliary shifter handles the “low speed†gear; in the lodging or high-yielding fields, assist in shifting the standard. Should be high speed; the height of the front of the divider is about 2cm. Harvesting method: Reduce the harvesting speed to avoid the counter-falling harvesting. Harvest the part of the vertical crop first. Finally, the reaped crops are harvested according to the actual situation, and can be harvested in a single direction by keeping the right tiller and rice stems at a distance of 15 cm from the right tiller. Do not rely on crop harvesting. Do not make the tiller contact the ground. (Otherwise, the abutment device will uproot the crop.) The crops fall on the fields and are lifted by assistants so that the driver can see the fields. At the field corner, try to increase the range of hand cutting. (3) Field sinking and maintenance of the combine harvester: It is necessary to correctly grasp the adjustment methods of each handle. And the maintenance of important departments. Mainly include: adjusting method of adjusting handle of threshing cleaning section, cleaning of intaglio screen, cleaning of auger joint, cleaning of pre-air cleaner, cleaning of vibrating screen, cleaning and adjustment of cutting knife, cleaning of wheel train and crawler belt Tightly and critically important parts of the machine are adjusted and maintained. When the harvester is often mistakenly entering the field pit during operation, the crawler shall be placed under the caterpillar, and the loading and unloading ramp should be retreated and pulled out with a tractor. The operation methods and unit maintenance of the combine harvester such as the Nantong Wushan-1.5 type and the Yanmar People's No. 5 self-propelled half-feeding type are generally close to each other. Please refer to the usage and maintenance manual for specific details. In short, the operator of the joint-stock machine owner must also pay attention: Knowing that during the rice harvest season, due to the effect of humidity and temperature difference between day and night, the night fog will gradually accumulate on the rice ear, rice stem and leaf surface, forming the so-called "dew." If rice is harvested when the dew is still dry, separation difficulties will occur, resulting in increased trash and loss. Therefore, joint harvesting should begin after the dew has basically dried up, and it is generally more reasonable after 8:30-9:00 in the morning. At the same time, if the combine harvester is to carry out cross-regional operations, it must also prepare enough frequently used consumables, spare parts and random supplies for food bags.

Always turn off the engine and clean the dust on the engine room's dust shield. Raise the header height properly without causing any harvesting loss. Pay attention to the messy straw in the conveying process and remove it in time when it is found to have accumulated.
