Since the 1960s, China's development and production of corn harvest machinery and pick spike institution has appeared three times. For the first time in the early 1960s, from the beginning to the cultural revolution was cut, the corn harvest during major mechanical technology introduction and absorption and theory research. No complete finalize the design production, The second from the mid-seventies onwards, lasted for more than ten years, from the introduction, USES, imitation, improving foreign machine developed by production into two stages, successfully trial-produced corn harvest machinery, more than 20 kinds. Among them, NongJiYuan China factory developed with about 4YW - 2 traction type lie roller corn harvest machine is typical in China, this machine is developed by the corn harvest machine, fill the blank of countries, The third from 1990's, remains, heat production unit up to over 100, has produced thousands of machines, tools is growing rapidly. To sum up basically has the following kinds of models:
1 and single-line corn harvest machine. The power of 11 ~ 14.7 KW, using rollers four-wheeled tractors and can pick a complete per panicle, corn pick and straw crushing processing operations. Representative machine is 4YZF - 1 type, 4Y118 type, production enterprises: zhengzhou tools factory, jinzhou NongJiChang, hebei giant NongJiJu etc. Machinery market price 10,000 yuan.

2 and armour type or drawing type corn harvest machine. The large 48KW ~ with 36.8 wheeled tractor kit, most models use rollers, also have picked per panicle type models use part of picking. But a complete line of the corn grain, grain picking, straw grinding machine parts processing, also has the stripping functions. Machinery market price for 2 ~ 4 million yuan. Line drawing machine, the representative of corn harvest machine is the harvest, because this type - 2 machine unit before too long, operation manual, saying to small plot, has rarely production. Do more fully represent models of corn harvest machines are: tianjin fukang company production 4YW - Q type, shandong HeGuoFeng feng yuxiang factory production 4YW - type 2, Beijing JinLe company production 4YW - 3, etc.

3 and more lines for corn harvest machine. This type of machine is used mostly plate, with fruit picking ear low losses, stripping effect is good, reasonable matching, flexible etc, adaptability and reliability than other models. The machine can do more than once completed the corn grain, grain, and skinning picking, straw crushing processing operations. Main representative models: gaomai city united harvest 4YZ production factory, handan is 2-3-4YJL production factory, the company production of shanxi letter 4YZ - type 2, etc. Machinery market price 10 million yuan of above.
4 and corn stalk corn harvester harvest machine. Time machine can harvest of corn straw green, achieve the goal that accepts stem a prototype. Representative models: hebei agricultural mechanization development institute of 4YZ - 4, tianjin agriculture machinery terminal and promote the development of tianjin fukang companies 4YW - Q type.
