Since the rear conveyor belt of the double conveyor is longer than the front one, the ears of corn fall to the ground later, and the thrown straw is laid on the ground in a neat strip at an angle to the direction of the machine, which is convenient for manual collecting and tying. The horizontal combine harvester with a reaper has good adaptability to different plant density, plant height, lodging degree and yield of rice and wheat, and has a simple structure; however, the longitudinal dimension is large, and the flexibility of the unit during operation is poor. It is mainly equipped with wheeled or walking tractors with a power of up to 15 kilowatts, and the cutting width is less than 2.0 meters. Each meter of cutting width can harvest 4-5 mu of wheat per hour.
Vertical harvester
The cut crops stand vertically on the cutter plane and are laid in strips next to the conveyor. There are two types of vertical combines: side laying and rear laying.
The side harvester consists of a crop divider, a crop star wheel (or a crop finger wheel), a cutter, a horizontal vertical toothed conveyor, etc. The cut crops are pushed by the crop star wheel to the upper and lower toothed belts of the conveyor, and the conveyor transports them horizontally to one side of the stacking machine.
The rear combine harvester has a set of triangular belts with pulling teeth, star wheels and spring strips for pressing the straw added every 30 cm between the two straw dividers to keep the china number data straw in a stable vertical state during horizontal transportation. After reaching the right side of the machine, it is transported to the rear by a pair of longitudinal conveyor belts, and the straw is laid in strips behind the machine by a straw pressing plate. This type of machine can prevent the straw strips from pressing on the corn seedlings when inter-row planting corn, and its cutting width is equal to the width of the wheat furrow between two rows of corn.
Vertical reapers-combines are compact in design, have small longitudinal dimensions, are light and maneuverable, and are suitable for harvesting rice and wheat on small plots of land. They are usually combined with hand tractors with a power of 7-9 kW or wheeled tractors with a power of about 15 kW, with a working width of 1.1-1.2 meters; there are also small self-propelled combines combined with special-purpose hand chassis with a power of 2-3 kW, with a working width of about 1 meter.
