Mini Harvester Advancing The Mechanization Of Harvest Operations
Small harvesters are a light weight harvester, divided into side-mounted and knot-style two. Breaking through the bottlenecks that rural areas could not enter into large harvesters, propelled the mechanization of harvest operations, shortened the labor cycle, and freed people from heavy manual labor. Widely used for harvesting wheat, rice, barley, hemp, beans and other crops. Replace the corresponding tool, install the upper and lower pallet and safe protective cover, you can also harvest shrubs, pastures, reeds and tea garden branches pruning and flower garden.
Harvest rice, harvest wheat, harvest soybeans, harvest corn, and stack it! For woodland cleaning, young forest tending, secondary forest transformation and forest tending cutting, etc. cutting shrubs, weeds, pruning, cutting small diameter wood. In the cutting machine equipped with some replaceable equipment or equipment, can also be used for harvesting rice and other crops, as well as pumping, playing hole drilling, spraying pesticides and other operations. The development of cutting machine is closely related to the development of small power machinery. After the Second World War, the Federal Republic of Germany, the United States, Sweden and other manufacturers of oil saws drive shaft and cutting parts as a chain saw accessories for mowing, shrub use. On this basis, Japan introduced and developed into an automatic harvester.
The small harvesters are divided into two types: side-mounted and back-type: ① Side-mounted small harvesters are equipped with hard shaft drive, mainly composed of engine, transmission system, clutch, working parts, operating device and side belt. A single cylinder two-stroke air-cooled gasoline engine and a centrifugal friction clutch are arranged at one end of the drive shaft, and a working part composed of a reducer and a cutting tool is installed at the other end. There are many types of working parts, commonly used for circular saw blades, blades or nylon filaments. Operation, the drive shaft of the aluminum alloy casing hook on the hook under the operator's shoulder, holding the handle, horizontal swing hard axis, you can complete the cutting weeds, shrubs and other operations. Machine weighing about 6 to 12 kg, the speed of about 4500 ~ 5000 r / min. ② backpack type automatic harvester. With the flexible shaft drive, the general structure and the side of the hanging brush machine is similar to the different engine back in the back of the operator, cutting parts driven by the flexible shaft, the engine power is generally 0.75 to 1.2 kilowatts. Between the engine and the back frame with two points and equipped with special rubber pieces to vibration. The flexible shaft is the flexible wire of the wire set in the hose to transmit the torque. The hose is a steel pipe wrapped around a metal braid with a rubber sheath to wind the soil into the shaft and keep the lubricating oil on the surface of the shaft. Fracture is generally between 1.5 and 2 meters.
Hand-held small harvester by the walking wheel to support the weight of the machine, by the people to promote the machine forward, driven by the engine working parts for cutting operations. Its construction and working principle is similar to portable cutting machine.
Suspension type small harvester hanging behind the tractor, driven by the power output shaft rotating parts, suitable for large area cutting irrigation operations. Mainly by the rack, saw blade, transmission, suspension and push plate and other components. During the cutting operation, the tractor retracts at a speed of 5 km / h and can be sawed with a diameter of 10 cm.
