How Does a Combine Harvester Work?

To operate a rice combine harvester working, we need to know its components and how each part is working, and when we need to turn it on and off. First of all, let’s get to know the names and uses of each part of the Wubota rice harvester.

As shown in figure 1, Divider (15) are the points on either side of the header which makes the header will not cut the grain and the crops are cut apart. The reel(1) is designed under the support of the cutter(2), including the ear part by feeding auger (3) to cut and feeder house joint, grilled by auger retracting tines to dial back again, finally by the feeder house (5) the slats scraping to the threshing rotor. Then let’s take a lot at the operation levers and buttons function picture.

operation levers and buttons function

  • 1. Cutting platform lever
  • 2. Threshing lever
  • 3. Throttle lever
  • 4. Stepless transmission lever
  • 5. Gear shift lever
  • 6. Combination switch (unloading lamp, header lamp, headlights, left/right turn lights, horn, dashboard light)
  • 7. Engine stop control knob
  • 8. Key switch
  • 9. Instrument Panel (gauges, hour meter, warning lights)
  • 10. Multi-function lever
  • 11. Brake pedal lock
  • 12. Brake pedal
  • 13. Reel lifting lever
  • 14. Unloading auger lever

The basic operation of the Wubota rice harvester working operation:

  • 1. Engine Start.

Start engine Inserting the key into the key switch (8) and turning to the location of the [on], honking to prompt. Then turn the switch key to the position of [start], Starting the engine. After starting, take your hands off the keys.

  • 2. Harvester Starting

Selected gear shift lever position, engine speed increased to 1500 rev/min or more. When on the ground, disengage the brake pedal lock (11), slowly pushed forward the stepless transmission lever (4), then the machine going forward. When pushing more, the faster machine forward. Back later, the stepless transmission lever (4) is pulled up to “S” shaped groove a bit, stop the machine forward, and pauses for 1-2 seconds later along the “S” shaped groove again after the pull, the more, the faster the machine back.

When On the slopes, slam the foot brake pedal (12), to disengage the brake pedal lock. (11), while the stepless transmission lever (4) is pushed forward, side release the brake pedal (12), the machine forward. Conversely, while the stepless transmission lever (4) backward slowly pulls, side-release the brake pedal (12), the machine back.

  • 3. Harvester Turning

Turn toward the direction of the hydraulic steering stem operation. Push the lever to A the harvester will turn left and push the lever to B the harvester will turn right.

  • 4. Harvester Parking

  1. Place the stepless transmission lever in the [stop] position.
  2. Pull the throttle lever back to the slow idle [tortoise] position.
  3. Place the shift gear lever in the [neutral] position and then hang up the parking brake.
  4. Lower cutting platform down to the ground.
  5. Shut down the engine, and pull out the switch key.

Harvesting work operating skills

How to operate a harvester working in different types of fields? Let’s see the skills following.

1. Crop divider position adjustment

Harvesting lodged crops, in order to reduce harvesting losses, caused by harvest way, please make sure the crop’s lodging status, and adjust the position of the divider.

A . Semi-lodging state

When harvesting the semi lodging crops, sometimes at the right side of the cutting knife. At this point, please take the right side of the divider close to the side of the noncutting crops (not cut the crops side) to carry out the harvest. In this case, the harvesting speed should be reduced slightly.

<2> Non cutting side crops

<3> Usual divider position

<4> Semi lodging crops

B. Harvesting the complete down crops

Please adjust the divider on the left to the position above the crops.

2. Adjust the harvester’s working speed

Confirm the crop and field condition, and choose the most suitable harvester working speed. Harvesting operations, for lodging angle large and high moisture crops, please reduce the harvester working speed. On the contrary, the small lodging angle and less water dry crops can accelerate the speed of harvesting. Harvesting lodging crops, please confirm the lodging condition, choose the correct direction of the harvesting.

Adjust harvester working speed

<1> Reverse cutting <3> Harvesting lodging left direction

<2> Smooth cutting <4> Harvesting lodging right direction

Adjust harvester working speed

<1> 45 degrees <A> Suitable for cutting. <2> 70 degrees below <B> Suitable for reverse cutting range <3> 85 degrees below <4> Complete down crops

Please refer to the following table and the operation of the stepless transmission lever through the switch of the shift gear lever.
