The rice combine harvester is an all-in-one machine for harvesting crops, which can complete harvesting and threshing at one time, collect the grain in a storage bin, and then transport the grain to a transport vehicle through a conveyor belt. It can also be harvested by hand, placing the straw of crops such as rice and wheat in the field, and then harvesting and threshing with a grain harvester. Crop harvesting machinery for harvesting stalks of grains and cereal crops such as rice and wheat. Includes harvesters, sun cutters, bale cutters, grain combines and grain threshers. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools.

side mount

It adopts hard shaft transmission, which is mainly composed of engine, transmission system, clutch, working parts, control device and side hanging belt. One end of the drive shaft of the small wheat combine harvester is equipped with a single-cylinder two-stroke air-cooled gasoline engine and a centrifugal friction clutch of 0.75-2kW; the other end is equipped with a working part composed of a reducer and a cutter. There are many types of working parts such as circular saw blades, blades or nylon wires. During operation, hang the shackle on the aluminum alloy sleeve of the transmission shaft on the operator's shoulder strap, hold the handle, and swing the hard shaft laterally to cut weeds and shrubs. The weight of the machine is about 6 ~ 12 kg, and the speed is about 4500 ~ 5000 rpm.

Driven by a flexible shaft, the overall structure is similar to that of a side-mounted brush cutter, except that the engine is on the back of the operator, and the cutting part of the rice combine harvester for mountainous areas is driven by a flexible shaft, and the engine power is generally 0.75 ~ 1.2 kW. The engine and rear frame are connected at two points with special rubber parts for vibration isolation. The flexible shaft is a wire flexible shaft that is sleeved in a hose to transmit torque. The hose is a threaded pipe wrapped with a steel belt, the steel belt is wrapped by a metal braided mesh, and the metal braided mesh is coated with a rubber protective sleeve to prevent dust from invading the shaft and keep the surface of the shaft lubricated. The cutting width is generally between 1.5 and 2 meters.

walking

The weight of the machine is supported by the walking wheels, the machine is pushed forward by a person, and the working parts are driven by the engine for cutting and irrigation operations. Its structure and working principle are similar to portable brush cutters. The hanging harvester is hung behind the tractor, and the power take-off shaft drives the working parts to rotate, which is suitable for large-area cutting and irrigation operations. It is mainly composed of frame, saw blade, transmission device, suspension device and push plate. During cutting and irrigation, the tractor travels backwards at 5 km/h, and bushes with a diameter of 10 cm can be seen.

horizontal

It consists of a reel, one or two front and rear canvas conveyor belts, a crop divider, a cutter and a transmission. During operation, the reciprocating cutter cuts the crop and turns it back on the canvas conveyor belt, which feeds the crop to the left side of the machine. Because the rear conveyor belt is longer than the front conveyor belt, the head part of the ear falls later, and the discharged straw is laid on the ground into a neat straw strip, which forms an oblique angle with the traveling direction of the machine, which is convenient for manual picking and bundling. The horizontal header harvester has good adaptability to the different growth densities, plant heights, lodging degrees and yields of rice and wheat, and has a simple structure; however, due to its larger longitudinal size, the device is more flexible in operation. poor, and it mostly matches wheeled or walk-behind tractors under 15 kW. The cutting width is less than 2.0 meters, and the harvested wheat per meter can reach 4 to 5 acres per hour. vertical

The crop to be cut stands upright on the plane of the cutter and is placed in strips outside the output machine near the conveyor. There are two types of side-loading and rear-loading: the side-loading harvester is composed of a grain divider, a grain pulling star wheel (or a grain pulling thumb wheel), a cutter, a horizontal and vertical toothed belt conveyor, etc. The cut crops are moved to the upper and lower toothed belts of the conveyor through the grain star wheel, and the conveyor transports them laterally to one side of the machine for laying. In the present invention, a set of V-belts with pulling teeth, star wheels and grass-pressing elastic strips are added every 30 cm between the straw dividers, so that the straw can maintain a stable upright state during the horizontal conveying process. After reaching the right side of the machine, a set of The longitudinal conveyor belt is conveyed backward, and with the cooperation of the grass press, the straw is laid into strips behind the machine. In the case of interplanting corn, this model cannot press the straw on the corn seedlings, and its cutting width is equal to the width of the wheat ridge between the two rows of corn. The invention has compact structure, small longitudinal size, lightness and flexibility, good operability, and is suitable for harvesting rice and wheat in small plots. Most of them are matched with 7~9kW walking tractors or 15kW wheeled tractors, and the cutting width is 1.1~1.2 meters; there are also small self-propelled harvesters equipped with 2~3kW walking chassis, and the cutting width is about 1 Meter.
