Description
Technical field
The invention belongs to the technical field of vegetable harvester tool, relate to seedling grass harvest machinery, say especially, 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, 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, there is very high edible and pharmaceutical value, welcome by Jiangsu-zhejiang Shanghai Area one band resident.Seedling grass can carry out 6 ~ 8 harvestings a planting season; at the Yangtze River Delta, form scale greenhouse gardening in recent years; yet its main vegetable grower of leaning on that gathers carries out hand harvest with scissors, reaping hook at present; labour intensity is large, cost is high, production efficiency is low; restrict its large-scale planting; yet the machinery that is not applicable in the market the harvesting of seedling grass, is 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 three: one, and booth area is less, spatially also has the restriction of canopy, and not having can be for the space of above-mentioned mechanical work; The 2nd, self-powered machinery and tractor generally be take diesel engine as power, and a large amount of oil gas of its generation and carbonic acid gas are difficult for distributing in booth, have a strong impact on the quality that affects vegetables, the health that a large amount of oil gas that machine work produces and noise also affect operating personnel; The 3rd, machine weight is large, and wheel is large to the effect of stepping on of the pressure of seedling grass, presses tread 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 guarantee the fresh of seedling grass, its results are necessary for combining, and it is short and continuous that harvest time is wanted; 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 CN201957453 U has announced a kind of seedling grass harvesting apparatus fast, comprises cutter sweep, blower fan, vehicle frame etc., adopts gasoline to provide power for cutter sweep and blower fan, and oil vapour pollution is large; By bolt and nut, realize cutting height and regulate, inconvenient operation; Publication No. is that the Chinese patent of CN10207728 A discloses a kind of seedling grass harvesting apparatus, and adopting electromotor is that cutter sweep drives cutter sweep, by changing axle sleeve, regulates cutting height, and operation is trouble comparatively; The walking manner of above-mentioned two patents is all people's pushing-type, by people, is pushing away machine and is advancing 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, while gathering in the crops,, because plant is short and small, the walking manner resistance that adopts people to push away was little; Pod bearing period results, due to the winding effect of seedling grass, it is excessive that operating personnel push away the resistance of machine, and labour intensity increases.
Summary of the invention
The problem to be solved in the present invention is to overcome above-mentioned technological deficiency, a kind of cleanliness without any pollution is provided, seedling grass is pressed that the effect of stepping on is little, cutting height is easy to adjust, can be reduced the electric self-propelled seedling grass grain header that is applicable to the harvesting of seedling grass of labour intensity.
