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 non-circular gear eccentric wheel rocking bar combined type 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 turn into China vegetables
Plant another dominance technology of future development.
" transplanting mechanism " is vegetable transplanting machine workpiece, and the European Community of first place in the world is 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 it is due to add slideway mechanism, greatly reduces production efficiency, 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, labor 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 harvest 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.
China is taking the automatic vegetable transplanting machine application aspect of cultivation one or blank, 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 the integral all automatic vegetables transplanter autonomous innovation research of cultivation
Lead, also lack the working mechanism that integral automatic transplanting mechanism is planted to taking and theoretical research, 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, it is domestic to take the research and development for planting integrated full automatic transplanting mechanism to substantially belong to copy to vegetables, do 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 take and plant integral 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 pot vegetable seedlings non-circular gear eccentric wheel rocking bar combined type 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 non-circular gear 15 is engaged with one-level upper planet non-circular gear 25 and one-level lower planet non-circular gear 8 respectively.When one-stage gear case 9
When being rotated relative to center non-circular gear 15, occurs transport motion, due to upper eccentric wheel 22 and lower eccentric wheel 3 and the non-knuckle-tooth in center
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 rocker 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 pushing away seedling cam 34, rotates
Cheng Zhong, because spring 35 is acted on, pushing sprout pole 31 is mutually collided with shift fork 33 so that shift fork 33 is contacted with pushing away seedling cam 34 all the time,
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 the effect of two clip slots 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.
The resultant gear ratio curve of the pot vegetable seedlings non-circular gear eccentric wheel rocking bar combined type transplanting mechanism as shown in figure 5, by
This drive characteristic realizes transplanting track as shown in Figure 8, moves in a direction indicated by the arrow, is position seedling taking shown in Fig. 9 in A points,
It is that position pushes away seedling shown in Figure 10 in B points, so as to realize the mechanization transplanting of vegetable seedling.
