Description
Technical field
The present invention relates to reaping corn and Robotics field, particularly relate to miniature electric corn both arms harvesterDevice people.
Background technology
After mechanization of agriculture originates in capitalism's intrusion agricultural, its development has usually been experienced three in European and American countriesStage: 1. semi-mechanization stage. In the middle of the 19th century to last years of a century substantially. Feature is in agricultural production, to be widely used animal powerThe simple agricultural machinery of traction. 2. the basic mechanization stage. To the 1950's substantially in 20 beginnings of the century. Feature isThe key operation of chief crop generally adopts the agricultural machinery of tractor-drawn. 3. comprehensive mechanization (or claiming high mechanization) rankSection. After approximately starting from the 1950's. Feature is agriculture, woods, herd, on the links of the each industry of fishing, and antenatal and postpartumDepartment, is all used more advanced farming machine widely. Since the eighties in 20th century, because electronic computer etc. is in agriculturalThe increasing of application, mechanization of agriculture is to automation development. The countries and regions of the third world, just in the world for the second timeAfter the war large, just bringing into use in varying degrees farming machine. But restricted by the factors such as politics, economy and technology, most so farThe Mechanization Level of country (area) is also lower.
Along with the development of mechanization of agriculture industry, its status in China's agricultural production is more and more important, and more nextMore obtain people's favor. In general, mechanization of agriculture, refers to the agricultural machinery equipment agricultural that uses advanced is applicable, improvesAgriculture production and management condition, improves constantly the process of agriculture production technology level and economic benefit, ecological benefits. Each in agriculturalIn department, use to greatest extent various machinery to replace hand tools to produce. One of substance of agricultural modernization. AsIn plant husbandry, use tractor, seeder, harvester, power irrigation and drainage machine, motor vehicles etc. to carry out ploughing soil, sowing, receiptsCut, every operation such as irrigation, field management, transport, make whole production processes mainly rely on machine power and electric power, instead of comply withComplete by manpower, animal power. Realize the mechanization of farm work, can save labour, reduce labor intensity, improve rural labor and produceRate, strengthens the ability that overcomes natural calamity.
Although there is now various agricultural machinery, still also have a lot of not enough, for example knob withAnd the development of mountain farming receives the restriction in its geographical position, large-scale harvester, seeder, machine of working soil etc. are difficult to directly enterConstructing in farmland, still needs artificial manpower work, so its productivity is still very low, peasant's labour intensity is still heavy,Cannot obtain more other productive lifes, and culture life. Especially when hand harvest's corn, its intensity is larger, andWhen harvesting corn, corn dead leaf can produce the swing of certain amplitude, and then incised wound face and staff. And when harvesting corn stillNeed be exposed to the sun, also larger to somatic damage.
