First, the main pre-operational preparations

1, 10-15 days before harvest, the field survey should be prepared to understand the operation of lodging the extent of field corn, planting density and spacing, the lowest panicle node height, size and length of land, etc., to develop a good work plan.

2, 3-5 days before harvest, the fields in the trench, filled large furrow, and in wells, no obstructions, such as pole lines to set up warning signs, in order to facilitate the safe operation.

3, the correct adjustment of straw crushed Field operating height, the general height of 8 cm stubble can adjust easy tool at too low a level playing soil, would result in excessive tool wear, power consumption, reduced equipment life.

Second, maintenance of equipment and maintenance

1, operating on the technical maintenance: ⑴ daily clean-up work should be ministries Combine corn residual dust, stems and leaves and other fixtures. ⑵ connect the various components of the inspection, the necessary fasteners. To check the particular device to crush the blade, the scraper conveyor and the fastening strip, the attention of wheels fixed to the wheel hub. Triangle ⑶ inspection, transmission chain, feeding and the degree of chain tension. Adjusted when necessary, should be the replacement of damaged. Deceleration ⑷ check box, enclosed gear lubricant me whether there is any leakage and inadequate. ⑸ check whether the hydraulic system of hydraulic oil leakage and inadequate. ⑹ timely clean-up the engine water tanks, dust cover and air filter. ⑺ engine according to the technical maintenance manuals.

2, the lubrication Harvester: Corn Combine all friction parts, must be timely, careful and proper lubrication, so as to enhance the corn Combine the reliability, reduce friction and power consumption. Lubrication in order to reduce maintenance time and increase corn Combine time utilization, corn combine harvester in the widespread adoption of the two sides of the single ring with ball bearings to the outer spherical Ball Bearings single row to the heart, does not require refueling during a certain period of time . However, some bearings and working parts (such as the transmission box, etc.), the requirements specification should be used regularly add or replace the lubricant oil.

3, triangle belt drive maintenance: ⑴ in use must be maintained at the normal belt tension. Too loose or too tight a belt will shorten the life. Too loose belt will slip, so that the loss of the effectiveness of the work of agencies; belt tight bearing excessive wear will increase power consumption, and even bending axis. James ⑵ the need to prevent the oil belt. ⑶ belt mechanical damage must be prevented. When hanging or unloading belt must be loosened round tension, if not on the new belt should unload a pulley, and then put the unloaded belt pulley fitted. Round the same loop of the pulley groove should be rotating in the same plane. Pulley flange ⑷ chipped or deformed should be promptly repaired or replaced. ⑸ loop with the same two or three belts, the length should be consistent.

4, the chain of transmission maintenance: ⑴ the same loop in the chain should be rotating in the same plane. ⑵ chain should be tight to maintain an appropriate degree, easy to wear too tight, too loose then beat big chains. ⑶ tightness when adjusting the chain, the screwdriver inserted between the roller chain to the chain pulled the direction of the movement, such as the tightness of the chain of appropriate, should be able to turn the chain of 20-30 °.

5, the hydraulic system maintenance and maintenance: ⑴ check the hydraulic oil tank, the harvest should be decentralized to the lowest position of Taiwan, such as hydraulic oil is low, should be added. ⑵ corn combine harvester new work should be replaced after 30 hours in the hydraulic tank hydraulic oil, replace the 1 after a year. ⑶ refueling refueling tank should be clean around the hole, removed and cleaned filter, new filter into the oil slowly through. ⑷ hydraulic oil should be poured into the sedimentation tank to ensure the hydraulic oil clean, does not allow the oil contains water, sand, iron, lime or other impurities.
