Abstract: Leaf vegetable output in our country is huge and has the considerable economic value. At present, artificial harvesting is the main method to harvest leafy vegetables, which restricts the development of industry seriously, so it is imperative to carry out the research on mechanized leaf vegetable harvesting. In order to understand the development status of the harvesting technology and equipment for leafy vegetables at home and abroad, this paper classified leafy vegetables and non-leafy vegetables, expounded the performance characteristics, applicable environment, working principle and technical advantages and disadvantages of key components such as cutting, conveying and so on of the representative models of leaf vegetable harvesting equipment at home and abroad, and analyzed the research status of profile modeling and automatic alignment of cutting table. It is concluded that the rootcutting consistency of the cutting parts of the existing nonheading leafy vegetables under soil cutting machine in our country is poor, and the clamping and conveying device damages the leafy vegetables greatly, and the problem of the standardized planting model is not formed, finally, a series of suggestions are put forward to carry out study on the shovel cutting parts under soil, strengthen the research on the basic physical and mechanical properties of leafy vegetables, and promote the development of the whole mechanized industrial chain.
