Combine Rice Harvester Construction & Working Principle

The medium paddy harvester machine mainly includes the Cutting platform (header), Middle transportation device, Threshing and cleaning device, Chassis, hydraulic and electric control systems and Motor.

• The Cutting platform (header): is an important component to the Combine harvester. It is to accomplish guidance of crops to be cut, then cutting the crops, immediately transported them to the side continuously, and through flexible allocation of transmission that continuously sent crops to the Middle transportation device.
• The Middle transportation device is hand-over equipment that connects the Cutting platform (header) and the Threshing and cleaning device of Combine harvester. Its function is to send the crops which come from the Cutting platform to the Threshing and cleaning machine, achieving continuous work process.
• The Threshing and cleaning device is to achieve separation of grain and stalk, reduce the impurity in maximum.
• The Chassis is an assembly of those systems that are the major operating part of combine harvester. It organically make the components of header, transport, threshing, cleaning, and gathering, etc. into a whole and changes the engine power into driving and operating power.
• The Hydraulic and electric control systems control starting, lighting and cutting platform lift of harvester.
• The Engine is the heart of combine harvester, providing engine power for driving and harvesting operations.

Service and Warranty of Combine Rice Harvester

• We provide technical guide for installation and operation.
• The machines are in three years guarantee except the wearing parts.
• We have English manual and working & maintenance CD which will help you learn, control and operate the machine well.

Attention for Using Combine Paddy Harvester

• Correctly adjust engine speed: In normal condition, if land is even, crop is mature and in the stage of yellow ripeness, field weed is less, we can improve the harvester’s forward speed appropriately.
  • If crops are in the beginning of yellow ripeness stage, heavy humidity, the speed should be slowly;
  • If crops are in the stage of yellow ripeness, low humidity and equally ripeness, the speed can be increased;
  • If in the morning and evening, as well as after raining, the crops stalks are heavy humidity, the speed should be slow when harvesting;
  • If crops are dense, high, and bumper, the speed should be slow; if crops are low density and thin grains, increase the speed.
• Reap width should be appropriate: under good condition of harvester, operate at full capacity as far as possible, handle the reap width with 90% of cutting platform, reduce miss reap.
• Correctly control stubble height: under normal harvest, stubble should be as low as possible, but it shall not be less than 6 cm, or else it will lead to cutting knife to eat mud, speed up the knife-edge wear and damage. Stubble height is generally not more than 15 cm as well.
• Correctly choose the working method: three kinds method allowed: 1. Clockwise rotation method to heart; 2. Turning clockwise to heart; 3. Spindle harvesting method. The general rule is: unloading grain convenient and quickly.
• Keep straight walking: allowing trace corrective direction. Stop harvesting when swerve.
• When finish harvesting, you should check and maintain the harvester based on <Harvester Instructions>, do remember all of these must be under condition that engine flameout to prevent accidents.
