Description
Technical field
The invention belongs to the technical field of vegetable harvester tool, relate to seedling grass harvest machinery, particularly, is a kind of electric self-propelled seedling grass grain header.
Background technology
Seedling grass, formal name used at school sickle alfalfa, is again three leaf vegetables, toothed burclover, and leguminous forage belongs to, the raw leaf vegetables of 1-2, and its stem is flat to crouch or tilts, and trifoliolate leaf, leaf are strong green, and essentialspecies is implanted in Yangtze River Delta one band.Because it is rich in multiple nutrients, have very high edible and pharmaceutical value, the dark Jiangsu-zhejiang Shanghai Area one that is subject to is with resident to welcome.Seedling grass can carry out 6 ~ 8 harvestings a planting season; scale greenhouse gardening is formed in recent years at the Yangtze River Delta; but it is gathered and main carries out hand harvest by vegetable grower with scissors, reaping hook at present; labour intensity is large, cost is high, production efficiency is low; restrict its large-scale planting; but be not applicable to the machinery of seedling grass harvesting in the market, be necessary to develop a kind of seedling grass grain header.
Self-powered rice and wheat grain header or be not suitable for seedling grass planting booth work by the harvesting facility of tractor-drawn.Main cause has be booth area less at three: one, spatially also has the restriction of canopy, and not having can for the space of above-mentioned mechanical work; Two be self-powered machinery and tractor is generally power with diesel engine, and its a large amount of oil gas produced and carbonic acid gas not easily distribute in booth, have a strong impact on quality affect vegetables, and a large amount of oil gas of machine operation generation and noise also affect the health of operating personnel; Three is that machine weight is large, and wheel is large to the effect of stepping on of the pressure of seedling grass, and pressure tread is long-pending large, is unfavorable for the subsequent growth of seedling grass.
Although seedling grass belongs to herbage and belongs to, grass making machinery is also not suitable for the harvesting of seedling grass.On the one hand, herbage mostly is swath harvesting, and in order to ensure the fresh of seedling grass, its results are necessary for combining, and harvest time wants short and continuous; On the other hand, herbage is animal feeding-stuff, and its harvesting work is comparatively coarse, and seedling grass is as edible vegetable, and its harvesting work must be meticulous.
Chinese patent CN201957453U discloses a kind of seedling grass fast harvesting apparatus, comprises cutter sweep, blower fan, vehicle frame etc., and adopt gasoline to provide power for cutter sweep and blower fan, oil vapour pollution is large; Realize cutting height by bolt and nut to regulate, inconvenient operation; Publication No. is that the Chinese patent of CN10207728A discloses a kind of seedling grass harvesting apparatus, and adopt electromotor to be that cutter sweep drives cutter sweep, regulate cutting height by changing axle sleeve, operation comparatively bothers; The walking manner of above-mentioned two patents is all people's pushing-type, namely pushes machine by people and advances in field.
To be that whole furrow are unordered broadcast sowing seedling grass planting mode, and from vegetative period to pod bearing period, consistency, stem stalk height all increase.Vegetative period, when gathering in the crops, because plant is short and small, the walking manner resistance adopting people to push away was little; Pod bearing period, is gathered in the crops, and due to the winding effect of seedling grass, the resistance that operating personnel push away machine is excessive, and labour intensity increases.
Summary of the invention
The problem to be solved in the present invention overcomes above-mentioned technological deficiency, provides a kind of cleanliness without any pollution, little to the effect of stepping on of seedling grass pressure, cutting height is easy to adjust, can reduce the electric self-propelled seedling grass grain header being applicable to the harvesting of seedling grass of labour intensity.
