Side hanging
The hard shaft drive is mainly composed of engine, transmission system, clutch, working parts, maneuvering device and side hanging belt. At one end of the transmission shaft, a single cylinder two-stroke air-cooled gasoline engine and centrifugal friction clutch are configured. The other end is a working part consisting of a reducer and cutting tool. There are many types of working parts, commonly used as circular saw blades, blades or nylon wires. In the operation, the hook ring on the aluminum alloy sleeve of the transmission shaft is hung on the back of the operator's shoulder, holding hands and swinging the hard axis horizontally to complete the work of cutting weeds and shrubs. The machine weight is about 6 ~ 12 kg, and the speed is about 4500 ~ 5000 RPM.
knapsack
With the soft shaft drive, the general structure is similar to that of the side-mounted cutting irrigation machine. The difference is that the engine is carried on the back of the operator, the cutting parts are driven by the soft shaft, and the engine power is generally 0.75 ~ 1.2 kw. The engine and the back rack are connected at two points and equipped with special rubber parts to vibrate. The flexible shaft is a steel wire flexible shaft in the hose to deliver torque. The hose is wrapped in a metal mesh covered with rubber cover, which is wrapped in a metal mesh, to prevent dust from breaking into the shaft and keeping the oil on the shaft surface. The cut is generally between 1.5 and 2 meters.
Walking type
By the weight of the travelling wheel support machine, the machine is pushed forward by the man, and the working parts are driven by the engine to cut and fill the irrigation work. Its structure and working principle are similar to the portable cutting irrigation machine. The hanging harvester is suspended from the back of the tractor, which is rotated by the power output shaft, which is suitable for large area cutting irrigation. It is mainly composed of frame, saw blade, transmission device, suspension device and push board. When cutting irrigation work, the tractor is back, working at a speed of 5 km/h, with a diameter of 10 cm in diameter.
horizontal
It consists of the rotary wheel, one or the front, two canvas conveyor belts, the divider, the cutter and the transmission device. In the operation, the reciprocating cutter, with the coordination of the plywood, cut the crop and backward the crop to the left of the machine. Double conveyor belt conveyor belt conveyor belt earlier after due to long, make the ear part be born late, and make the discharge of straw on the ground paved with the machine into a direction Angle of the article and tidy grain, and facilitate the artificial pick up after. The horizontal cutting machine has good adaptability and simple structure for rice and wheat different growth density, plant height, inverted degree, yield and so on. But the longitudinal size is larger, unit, poor flexibility when working under todays 15 kw wheel or walking tractor kit, cutting length is less than 2.0 meters, the cutting length per meter per hour can be 4 ~ 5 acres of wheat.
vertical
The cut crop stands upright on the plane of the cutter, and the conveyor is placed on the outside of the machine. There are two kinds of side - laying and post-laying: the side - laying type harvester consists of the divider and the paddle-wheel (or the paddle-wheel), the cutter, and the transverse vertical gear conveyor. The cut crop is allocated to the conveyor's upper and lower gears by the paddles, and the transporter transports it horizontally to the side of the machine. After laying type harvester every 30 cm between two grain is a group with a dial the tooth triangle is designed, the pressure wheel and hetian play, make the straw in the process of lateral transfer stable state of upright, arrived at the machine right back by a vertical conveyor belt conveyor, straw in conjunction with the pressure of grain board in the rear article laying into the machine. In the case of corn, this type of model can not be pressed into the corn seedling, which is equal to the width of wheat in the two rows of corn. The vertical cutting machine has compact structure, small longitudinal size, light and flexible, good maneuverability, suitable for harvesting rice and wheat on small plots. With a range of 7 ~ 9 kilowatt, or about 15 kilowatts of wheeled tractor, 1.1-1.2 m. There are also 2 ~ 3 kw hand support special chassis matching small self-propelled harvester, cut about 1 meter.
