小型多功能联合作业耕耘机设计

微型耕耘机具有体积小、质量小和方便运输等优点,适宜在丘陵山区作业。我国的微耕机近年来经历快速发展[1],现已能基本满足农业生产要求;但是,国内微耕机大多只能完成某一特定作业,功能单一,且工作稳定性不好。为此,提出一种具备深松、推土、旋耕等功能的乘坐式小型多功能联合作业耕耘机,能同时完成两项作业,且能根据作业要求更换配套工作部件;其配备液压控制系统,可有效调节后旋耕部件耕深,并对工作部件起到过载保护的作用。田间试验表明:其作业效果良好,并具有较好的操纵性和工作稳定性,能较好地满足丘陵山区的作业要求。

Design of Utility Combination Process Micro-cultivator

Micro-cultivator , having the advantages of small size , light weight , convenient transportation , is suitable for operation in hilly regions .Owing to its great market prospects , micro-cultivator can basically meet the requirements of agricultural production now after its rapid development in recent years .However , most of the domestic micro-cultivator can do only one specific job and perform bad in working stability .In order to solve these problems , this paper puts for-ward a new kind of utility combination process riding micro-cultivator which has the ability of subsoiling , bulldozing , ro-tary tillage and so on .Also , it can once complete two operations and can meet the requirements of agricultural production by changing its working parts .The hydraulic control system , which is placed on the micro-cultivator , can effectively ad-just the depth of rotary tillage part and protect the working parts from overload .Field trials have proved that the micro-cultivator , performing good at operation effect , maneuverability and working stability , can well meet the requirements of agricultural production in hilly regions .
