2. Can the three adjustments of the whole column and the alignment be qualified?
3, the gap of the blade cutter is fine.
When cutting, the cutter should be disconnected from the driving device; if one hand can pull the cutter gently, it is proved that the equipment adjustment is correct.

1, the rod (and nail teeth); the fixed condition of the concave plate and the drum assembly. To check the locking condition of each nut one by one.
2. Check whether the threshing gap (including the threshing gap of the nail roller) can be uniform. When viewing, the concave plate should be raised to the highest position; then change the roller; check whether the roller and the concave plate, the end surface of the roller and the side wall can have the scratching appearance Whether the change can be simple and sensitive.
3. Check the balance of the drum.
4. Verify that the indication readings of the threshing gap adjustment handles are common to the practice gap.

Finally, hit the shaft head with a hammer; the shaft does not move; and has elasticity; The equipment with the inner ring of the bearing is tight.
1. The model of the pulleys between the sprocket wheels of the same transmission circuit should be in the same plane; the pulley shafts should be parallel. ; not skewed, the center of each sprocket in the same transmission circuit should be installed in the same plane; each sprocket shaft should be parallel; not skewed.
2. The pulley and sprocket are firmly on the shaft; the beating is small.
3. Check whether the orientation and gap of other adjacent components are correct.

Beijing 2. 5 and Spring Breeze 5 should pay attention to the riveting condition of the skewed conveyor plate; there must be no loose appearance.
2. Check the fastening condition of the top wire or the shaft end bolt and the shaft nut which are positioned on the shaft of each pulley and sprocket; to avoid the pulley and the sprocket from swimming during the operation; the rolling key or the detachment of the surface.
ㄆ撸┘觳榱蛹å‘浜锨æ¦The demand cooperation gap is suitable; avoid premature wear and damage.
It is necessary to have 80% of the teeth or corrugations of the main driven discs; the maximum gap of the teeth or corrugations that cannot be tightly combined shall not exceed 1 mm.
2. The tightness of the tension spring should be adjusted to the extent that the tension spring can be changed by one hand force. The sum of the gaps between the rings should ensure the sliding disc change (that is, the sum of the gaps between the turns of the spring should be larger than the teeth). high).

The initiator is at a low speed; the oil pressure is not lower than 0.5 kg/cm 2 for an additional speed. When the oil pressure should not be less than 1.5 kg / cm 2 . In the start of the machine operation; be careful to listen to the presence or absence of abnormal sound; look at the appearance of the reading; check the presence or absence of oil leakage in the local empty work to reach 10 15 minute.
2, some of the empty test operation of the threshing: adjust the gap of the drum to the maximum orientation; open the lower cover of each elevator; change the pulley of the central drive shaft by hand; make the whole machine change after the machine is turned. After the machine is viewed normally The starter can be started; when the speed reaches 600 800 rpm; the joint de-cold is somewhat. Then gradually increase the throttle to reach the normal test operation for 20 hours. At this moment; park every 20 minutes; check the bearing heat Condition; the fastening status of each department. Found faults; should be promptly removed.
3, walking some empty test operation; combine harvester walking empty work; should gradually improve the gear position from the beginning of a gear; punctual lifting and harvesting the harvesting platform and reel; pay attention to listening to some of the noise; see the gearbox with or without Oil spill and overheating appearance.
4, with load test operation: after 25 hours of walking some empty test after the test; the machine is normal; can carry out the load test operation. During the test run, the crops in the flat area are harvested without weeds and non-falling crops; when starting the test, the low speed should be used first. Gradually increase the load of the machine. After 15 hours of test drive; perform a full skill protection; remove the oil filter; replace the oil in the bottom of the engine oil; and follow the difficulties presented in the test run; make all adjustments; 3. The crew is put into the harvesting work under outstanding skill conditions.
Third, the use of combine harvester. ㄒ唬┨锛渥 㷠㷠㷠㷠㷠㷠㷠㷠㷠㷠㷠㷠㷠㷠收割 收割 收割 收割 收割 收割 收割 收割 收割
2, select the crew walking route; according to the crop topography; determine the harvesting plan.
3, eradicate the obstacles in the field; necessary to do a significant symbol.
4. Harvesting with a tractor-type combine harvester; cutting the sidewalk in advance; cutting the grain-discharging road for a long time.
Ǘ┦å´ç½¨é¥• 钡牟 stool child 1, the combine harvester 10 15 meters away from the crop to be cut; should smoothly engage the working clutch at low speed; make the working parts work, pull the operating valve to slow down the combine harvester; Reduce the harvesting table to the normal cutting height, then gradually increase the throttle; let the initiator harvest at the extra speed.
2, harvest 50 100 meters in the future; parking should check the quality of the work; if necessary, make appropriate adjustments. Then run 50 100 meters; then check the adjustment; until the quality of the work reaches the demand; then put it into normal operation.
3. After normal harvesting; the driver should adjust the height and speed of the reel, the height of the harvesting table and the traveling speed in time, pay attention to the investigation of the appearance and lighting signal equipment, listen to the sound of each working part; and find the abnormal appearance; Timely parking; find out the reason; remove the problem.
4. Normal harvesting; it is not allowed to reduce the travel speed by reducing the throttle; avoiding the formation of work quality degradation or blockage. At this moment, the hydraulic operated valve handle can be placed in the deceleration orientation; to reduce the travel speed of the machine.
5, after the operation of the obstruction. Should slow down the speed of travel; close to the obstruction; raise the harvesting station properly; skip the obstruction and drop the harvesting station; this process should not reduce the speed of the launching machine; A larger turning radius should be used.
6. Turning and harvesting operations. When turning and harvesting; should travel at low speed (but not reduce the throttle); avoid sharp turns; prevent overwhelming crops;
Fourth, pay attention to matters and safe operating procedures 1, start the machine to start, engage the clutch and walk before; it is necessary to announce the signal; to ensure the safety of the device and personal.
2. The driver should pay attention to the operation status and work quality of each component during the operation; find the problem and deal with it in time.
3. Depending on crop conditions, climate change and harvesting time; the relevant components and travel speed should be adjusted at any time to ensure the quality of the work.
4. When harvesting at the beginning of each plot; it should be operated at a low speed; for viewing and investigation; then gradually speed up.
5. During normal operation; do not touch the working parts by hand, and various adjustment and protection should be carried out after the start of the machine.
6. Before the header is not placed firmly on the support; stop the personnel from working under the header.
7, always look at the reliability of steering and braking tissue.
8. Stop using the harvester to tow other equipment.
9. When the operation is stopped; the shifting should be placed in the neutral position in time; do not leave the working clutch or the closed initiator.
