Design Of Mini-type Herbage Harverster

As a result of the adjustment of the infrastructure of agricultural production, the portion of livestock production in agriculture is ever increasing, and the corresponding farm ing area for herbage is constantly expanded. In Jiangsu Province,most of the herbage farms at present are medium or mini-sized and invariably located in hilly lands. Herbage harvesting is generally performed manually 4to5 times each year, having a low productivity , high cost and labor intensity. The newly emerging herbage industry is urgently demanding economical mini-type herbage harvesters.Considering the up-to-date characteristics of livestock production, the development of herbage harvesters should center on medium to mini-sized models. The high workload and labor-intensive herbage production should be a focus for research and a key problem to be solved. With regard to scales of herbage farms, the present cutting-devices of reciprocati ng and disc models can not solve cutting problems effectively. Thus the aim of this paper is to develop new theories for cutting, and by applying theoretical analyzing, computer aided design and experimental test, we developed a high-speed double reciprocating cutter which solved the cutting requirement by both soft and stiff stalks.Based on this, a research program is initialized which thoroughly considered the poor harvesting effect of combine harvesters on soft materials such as dark wheat grass. And as an alternative, a new scheme is provided to equip with mini-scale power unit to develop a double-propelled light-weight herbage harvester.The paper fully applied method of machine design on the development of double-pro pelled mini-scale herbage harvester, to design individual parts and perform load analyzing a nd strength evaluation. And then the software of AutoCAD and Pro/ENGINEER were used to complete the whole series drawings for the machine.
