Description
Technical field
The invention belongs to agricultural mechanical field, more particularly to it is suitable for one kind of all automatic vegetables potted-seedling transplanting requirement and has
Take the bevel gear-elliptic gear eccentric wheel rocking bar combined type wide-and narrow-row transplanting mechanism for planting integrated feature.
Background technology
China's vegetable cultivation has the tradition of intensive cultivation, due to the resources supplIes having a large population and a few land, determines China vegetables
Plantation need to combine China's economic technology condition, walk standardization, the development of low cost.Mechanized cultivation will be as China vegetables
Plant another dominance technology of future development.
The line space of vegetables rice transplanter institute rice transplanting seedling carries out one wide one narrow planting patterns, and this planting patterns utilizes crop side
The principles of increase yield of border advantage, by adjusting the line space of rice transplanting, increases vegetables ventilation and illumination, so that increase leaf area index,
Disease can be mitigated, extend leaf longevity, accelerate dry-matter accumulation, reach good quality and high output, the purpose of cost-saving synergistic.
" transplanting mechanism " is vegetable transplanting machine workpiece, the European Community in first place in the world on dry land transplanter
The core work part of vegetable transplanting machine is typically made up of 3 sets or 4 covering devices, completes seedling taking, 3 actions of conveying and plant, knot
Structure complexity, high cost, efficiency are low.In order to simplify the internal structure of an organization, the pot vegetable seedlings transplanter that Japan develops employs Liang Tao mechanisms, by it
Middle seedling taking and conveying device unite two into one, and employ and turn round the complexity that the mode being combined with slideway mechanism completes seedling taking and conveying
Action.But due to increased slideway mechanism, production efficiency is greatly reduced, it is per minute to transplant 40 times.Working time is long
, slideway is easy to wear, and functional reliability is difficult to ensure that.
The transplanter of current domestic application is generally artificial semi-automatic transplanter tool, mainly has flexible disk formula, chain-clip type, leads
The type such as seedling tubular type and basket-hanging.It is required that operating personnel feed, seedling is accurate, rapid, can not be interrupted, and inefficiency, labour intensity are big,
Cause whole machine operating efficiency low, the operating efficiency of general country's transplanter is only equivalent to artificial 5-15 times, far below it is cultivated it is whole,
Efficiency of the machinery such as results relative to manual work.Efficiently, it is that following large area transplants work gently to simplify full-automatic pot seedling transplanter
The developing direction of industry.
The automatic vegetable transplanting machine application aspect of one or blank are planted taking by China, and its research work is at the early-stage.Pass through
Document Investigation, the domestic nearly no document report taken about development in terms of cultivation one all automatic vegetables transplanter autonomous innovation research
Lead, also lack the working mechanism and theoretical research that one automatic transplanting mechanism is planted to taking, only to seedling taking, plant seedling respectively by removing seedling
Mechanism and the automatic vegetable transplanting machine of plant setter structure have correlative study.
At present, the domestic research and development that vegetables are taken with cultivation integrated full automatic transplanting mechanism substantially belongs to copy, and does not have
Great improvement and technical breakthrough, and external transplanter complex structure are carried out to external transplanter, it is expensive, and
Hardly possible adapts to the agriculture requirement of China, difficulty is promoted at home very big.Therefore design a kind of new taking and plant one all automatic vegetables alms bowl
Transplantation of seedlings mechanism has turned into the active demand of China's vegetable cultivation industry development.

The operation principle of the bevel gear-elliptic gear eccentric wheel rocking bar combined type wide-and narrow-row transplanting mechanism is：
Power is delivered on center sprocket wheel 1 by the drive sprocket 28 in transmission case 27 through chain 26, drives 2 turns of central shaft
Dynamic, central shaft 2 drives one-stage gear case 9 to rotate, in one-stage gear case 9, during empty set is fixed on central shaft 2 with transmission case 27
Heart elliptic gear 15 is engaged with one-level upper planet elliptic gear 25 and one-level lower planet elliptic gear 8 respectively.When one-stage gear case 9
When being rotated relative to center elliptic gear 15, there is transport motion, due to upper eccentric wheel 22 and lower eccentric wheel 3 and center ellipse tooth
Wheel 15 is fixed, and upper connecting rod 22 and lower link 3 are driven in the rotation process of one-stage gear case 9, and upper rocking bar 24 and lower rocking bar are driven therewith
7, because upper rocking bar 24 is fixed with one-level upper planet axle 18, lower rocking bar 7 is fixed with lower planet axle 6, and eccentric wheel endplay device drives
Two secondary planet trains, swing the versus primary gear-box 9 of secondary gearbox 16, under train effect, two grades of upper planet axles
20 relatively rotate with two grades of upper gear box 16, i.e., transplant arm housing 32 relatively rotates with seedling cam 34 is pushed away, and rotates
Cheng Zhong, because spring 35 is acted on, pushing sprout pole 31 and shift fork 33 are mutually collided so that shift fork 33 all the time with push away seedling cam 34 and contact,
In rotation process, because the non-circular profile line for pushing away seedling cam 34 is acted on, shift fork 33 is rotated relative to transplant arm housing 32, and drive is pushed away
Seedling bar 31 is moved forward and backward with respect to transplant arm housing 32, due to two effects of clip slot of stopper slot on pushing sprout pole 31, in pushing sprout pole
31 and the relative translational movement of transplant arm housing 32 during, intermediate plate 30 realizes continuous clamping, relieving action, and the seedling taking when clamping is put
Seedling is planted in ejection to pushing sprout pole 31 rapidly when opening.
