Mr. Du's invention 杜世金是泊里镇一名土生土长的农民，由于经常跟农机打交道，他逐渐发现市面上的农机大多都需要改进。他也因此萌发了自己制造农机的想法,并于2004年开始着手花生联合收割机的研制.杜世金坚持参加山东、江苏、河南等地举办的全国农业机械展销会，观摩和请教国内的农机制造专家. 2年后杜世金造出的第一台机器, 后又对机械不断进行的试验和改进，终于研制出这台应用了多项国内领先的技术的花生联合收割机.这台花生联合收割机的前端有两只雪亮的钢铲，机器开动时，钢铲伸进土里把花生挖掘出来，并合在一起“捧”给机器上的链条，链条夹住花生秧将花生传送到收割机的采摘区，将花生和泥土采摘下来。和泥土混合在一起的花生经过“手搓式”分离后，泥土从收割机的下面排到田地里，花生则经过层层过滤自动装入容器里。运用该机器，一亩地左右的花生不到半小时就可收割完毕，且几乎找不到遗落的花生。另外这台花生联合收割机采用了国内诸多领先技术，如驱动装置是采用液压传动. 操控装置是采用电磁阀控制，和“手搓式”的分离装置. 杜世金打算向有关部门申请专利。 As a farmer, Du Shijin found that most agricultural implements on the market need improving since he always use them. He also decided to invent agricultural implements by himself and began to make his peanut combine harvester in 2004.Du carried on taking part in the national agricultural machinery exhibitions held in Shandong, Jiangsu, Henan, etc. to visit other implements and learn from domestic agricultural machinery makers. Two years later, that is, in 2006, he made his first model machine. Then he did experiments and improved it constantly and finally invented this peanut combine harvester with several leading domestic technologies. There are two steel shovels in the front of this machine which would dig peanuts out together with soil after the machine is started and then send the peanuts to a chain which would hold the vines to send them to the picking area. In this area, peanuts and soil would be picked from the vines. Then, after the “hand-rubbing like” separation, the soil would be dropped to the land while the peanuts would be put into a container after several times of filtration. By using this machine, one Mu peanuts would be harvested in less than half an hour and few peanuts would be left in the land. Besides, this machine adopts several leading domestic technologies, such as, hydraulic drive, electromagnetic valve control and “hand-rubbing like” separation device. Du decided to apply patent for his invention.
