【摘要】 叶菜种植全程机械化可以有效提高生产效率，以酒泉本地叶菜种植条件为基础，设计一款适用于设施农业种植叶菜的通用型叶菜收获机械。收获机外形尺寸为长1 200 mm，宽660 mm，高800 mm，结构由机架、行走机构、切割装置、切割驱动机构、输送机构、输送带驱动机构和电控装置等组成。切割装置选用往复铲;输送装置由输送带和输送带驱动机构组成;输送带由三级串联，第一级为对行拾取输送带，第二级为并行输送带，第三级为翻转输送带;行走机构由两部分组成，前部转向支持轮使用一对万向轮，同时起到仿形作用，后部为支持驱动轮。更多还原

【Abstract】 The full mechanization of leaf vegetable planting can effectively improve production efficiency. Based on the local planting conditions of leaf vegetables in Jiuquan,this paper designs a universal leaf vegetable harvesting machine suitable for facility agriculture. The dimensions of the harvester are 1 200 mm in length,660 mm in width,and 800 mm in height. The structure of the harvester consists of a frame,walking mechanism,cutting device,cutting drive mechanism,conveying mechanism,conveyor belt drive mechanism,and electrical control device. The cutting device uses a reciprocating shovel. The conveying mechanism is composed of a conveyor belt and a conveyor belt drive mechanism. The conveyor belt consists of three stages in series: the first stage is an aligned pickup conveyor belt,the second stage is a parallel conveyor belt,and the third stage is a flipping conveyor belt. The walking mechanism consists of two parts,with the front steering support wheels of the leaf vegetable harvester using a pair of universal wheels,which also serve a contour-following function,while the rear part consists of supporting drive wheels.更多还原
