Correct use and maintenance of agricultural harvester

With the rapid development of China's rural economy and the use of combine harvester, the labor intensity of farmers has been greatly reduced. This paper discusses the correct use and maintenance methods of agricultural harvester, hoping that users can have a deeper understanding of agricultural harvester. Thus, it can better play its role and increase its operation intensity, so that its role can be brought into better play.

Harvester use

1. Pre-harvest book: check whether the parts of the harvester are in good condition.

2. Drive the machine into the field, then pull the grass pole to the working position, put down the grain receiving station, pull the grain removal gate to the "open" position, hang the grain bag on the hook of the grain bag, and guide the machine to the vertical position of the ridge of the field.

3. Debug the machine: the dust feed adjustment handle is pulled to the "standard" position, the auxiliary transmission handle is pulled to the "high speed" or "low speed" position according to the crop conditions, and the grass arrangement handle is placed in the "grass cutting" or "grass discharge" position.

4. Lower the cutting table and lower the front end of the divider to 5-10cm off the surface of the field.

5. Pull away from the clutch and cut the clutch handle to the combined position.

6. Push the main transmission handle forward slowly so that the machine begins to harvest.

7. When the crop begins to enter the threshing mouth, operate the manual adjustment switch of threshing depth to make the ear head in the position of breaking away from the depth indicator.

8. After all the crops have been harvested, pull the clutch handle to the separate position.

9. When there is no more grain at the grain outlet, pull the clutch handle of the threshing machine to the separation position.

10. Check whether the switches of all parts of the machine are turned off.

11. Reduce the throttle and the engine flameout.

12. Drive the harvester back to the placement point and carry out some inspection and maintenance.

(1) self-propelled combine harvester

1. Add lubricating oil to each lubrication point every day as required.

2. After using for a period of time, tighten the front and rear wheel nuts; check and adjust the tension of all triangular belts; check and adjust all transmission chains; when the indicator light is on, clean the dry air filter: clean the rotating air hood and radiator; check the cooling level and fill up; check and clean the water collector; check the fuel filter to release the deposited water and sediment; clean the filling port of the hydraulic tank and check the oil level. The combine harvester stops on the flat ground, check the engine oil bottom kettle oil and refuel as needed; tighten the unloading grain and stir the dragon wire rope; clean the refueling port of the hydraulically driven fuel tank and check the oil level. Clean the cab filter if necessary.

3. After 1 quarter of use, replace the fuel filter element and the engine oil filter. Check the specific gravity of the battery electrolyte and charge or fill it with distilled water as needed. Check the coolant level and fill it up. Clean the fuel pump, check and adjust the running clutch clearance, check and adjust the foot brake, adjust the soft shaft of the hand brake.

(2) maintenance measures of combine harvester

The combine harvester can maintain the machine before leaving the car, keep it in good technical condition, reduce the failure time, improve the work efficiency and prolong the service life of the machine.

1. Add and replace vulnerable parts.

2. Check the technical status of the engine, including whether the oil pressure, oil temperature and water temperature are normal, whether the sound fuel consumption of the engine is normal, etc.

3. Clean the combine harvester, remove the glume, broken stalk and other attachments on the machine, lubricate all the friction parts in time, and clean the outer chain and lubricate it with oil.

4. for the inspection of the separation device and the cleaning device, the inspection of the scripter should be the flexible rotation of the crankshaft after tightening, and the axial flow drum separation device is mainly to see whether the rotation of the drum is light, flexible and reliable.

5. The inspection and adjustment of the harvester, including whether the rotation speed and height of the cutting wheel, cutter stroke and cutting clearance, the clearance between the stirring dragon and the bottom surface and the rotating speed of the stirring dragon meet the requirements.

6. Inspection of threshing device. The main reason is that the drum speed concave clearance should meet the requirements, the speed is higher and the gap is smaller, but it should not cause grain fragmentation and drum blockage.

7. Check other items. Whether there are cracks in the weldment, whether all kinds of oil and water are clean and sufficient, whether the fasteners are firm, whether the movement of the rotating parts is flexible and reliable, whether the control device is flexible, accurate and reliable, especially the hydraulic control mechanism, it must be accurate when used.

(3) self-propelled combine harvester

1. Add lubricating oil to each lubrication point every day as required.

2. After using for a period of time, tighten the front and rear wheel nuts; check and adjust the tension of all triangular belts; check and adjust all transmission chains; when the indicator light is on, clean the dry air filter: clean the rotating air hood and radiator; check the cooling level and fill up; check and clean the water collector; check the fuel filter to release the deposited water and sediment; clean the filling port of the hydraulic tank and check the oil level. The combine harvester stops on the flat ground, check the engine oil bottom kettle oil and refuel as needed; tighten the unloading grain and stir the dragon wire rope; clean the refueling port of the hydraulically driven fuel tank and check the oil level. Clean the cab filter if necessary.

3. After 1 quarter of use, replace the fuel filter element and the engine oil filter. Check the specific gravity of the battery electrolyte and charge or fill it with distilled water as needed. Check the coolant level and fill it up. Clean the fuel pump, check and adjust the running clutch clearance, check and adjust the foot brake, adjust the soft shaft of the hand brake.

Harvester maintenance

(1) removal of sundries

① thoroughly removes all the components and connections of the machine, paying special attention to cleaning the pick picker and removing the residue on the return plate.

② cleans the return disc of the cleaning machine.

③ removes residue from rollers and recesses.

④ must clean up the grain in the granary and the elevators.

(2) complete lubrication-lubricate according to the lubrication rules, and then turn the machine a few times. At each connection, apply plate oil or Vaseline to prevent oxidation.

(3) some parts of the wheat combine harvester should be unloaded and kept separately.

In order to keep the combine harvester in a good technical state, ensure its high quality, low consumption and safe work, reduce the failure rate of the combine harvester, prolong the service life, and improve the economic benefit, it is necessary to use the combine harvester scientifically and rationally. seriously and carefully do a good job of daily maintenance and regular inspection.
