液压驱动式红枣收获机的设计

Design of Jujube Harvester Based on Hydraulic Driven

枣树为多年生木本植物。近年来我国红枣种植规模不断扩大,但是多数地区红枣的采摘仍旧延续手工作业的方式,劳动强度大、效率低、成本高,严重制约了红枣产业的发展。为解决上述问题,本文设计了一种采摘效率较高,可一次性完成采摘、收集、清选、分级等作业,并且能够适应丘陵和平原等多种地形的液压驱动式红枣收获机。首先根据枣树枝干的物理特性设计齿距可调的多行齿振动拨叉,以减少振动拨叉对枝干的损伤;其次通过试验测定果柄分离力学特性,为关键装置设计提供参考;最后通过ADAMS软件对振动机构进行运动分析,表明该机构能够满足设计要求。该红枣收获机可与多种型号的拖拉机配合使用,通用性较高,不伤树,能够适应多种地形和路况。

Jujube is a perennial woody plant.In recent years,the planting area of red jujube has been expanding,but the picking of jujube in most areas still continues to be done by manual operation.It has labor intensity,inefficiency and high cost,which seriously restricted the development of jujube industry.In order to solve these problems,a hydraulic driven jujube harvester,which can efficiently finish jujube picking,collecting,cleaning and grading at a time,was designed,and it could adapt to various terrain such as hills and plains.According to the physical characteristics of jujube branches,the vibrating fork with adjustable teeth distance was designed,which could reduce the damage to the tree branches;Secondly,the mechanical characteristics of separation for the fruit and stalk was tested,which provided a reference for the design of key equipment;Finally,the motion analysis of the vibration mechanism was carried out by Adams software,and the analysis results showed that the mechanism could meet the design requirements.The jujube harvester could be used in combination with many types of tractors.It had universal applications,no injury to trees,and could adapt to various terrain and road conditions.
