Particularly, can arrange proximity switch 242 in initial position, proximity switch 242 is connected in frame 10, and peg assembly 22 arranges proximity switch induction pieces 243.Driven unit 22 comprises variable step liquid damped cylinder 231 and one-way clutch 232, and variable step liquid damped cylinder 231 is connected on conveying axis 211 by one-way clutch 232, realizes one-directional rotation.First by horizontal for seedling dish 300 fixing on peg assembly 22, and by each parts position of adjustment, ensure that seedling dish 300 is by height, needs the position supported, distance fixing between two dishes.Again seedling dish size is inputted in control system 30.When transporting beginning, variable step liquid damped cylinder 231 stretches out, seedling dish 300 is at a distance transported to top seedling position A, when being with the peg 221 of approach switch sensor 243 by initial position and proximity switch 242, variable step liquid damped cylinder 231 shrinks, be subject to the effect of one-way clutch 232, driving shaft 233 stops operating, namely course of conveying stops, now encoder 241 starts effect, encoder 241 first records conveying axis 211 end point position, then signal is sent by control system 30 to variable step liquid damped cylinder 231, variable step liquid damped cylinder 231 stretches out again, one-way clutch 232 resets, course of conveying operates again, when the delivered length l of conveyer belt 212 corresponding to the angular displacement of conveying axis 211 that encoder 241 is measured is a-c, namely the cavities of the first row cave alms bowl body 310 of seedling dish 300 moves to A place, seedling position, top, sent by control system 30 and cease and desist order, variable step liquid damped cylinder 231 shrinks, conveying axis 211 stops operating, start to get, top seedling action, and count 1 time.When getting, after top seedling terminates, variable step liquid damped cylinder 231 stretches out again, from this conveying, when the distance of corresponding conveyer belt 212 movement of the angular displacement turned over that encoder 241 is measured is cave distance b, send stop signal, variable step liquid damped cylinder 231 becomes stepping conveying, namely the second row cave alms bowl body 310 of seedling dish 300 moves to A place, seedling position, top, variable step liquid damped cylinder 231 shrinks, conveying stops, get, after top is terminated, and count 1 time, variable step liquid damped cylinder 231 stretches out again, a cave pass by again apart from b, variable step liquid damped cylinder 231 shrinks again, conveying stops again, until young plant is all exhausted, now be counted as n time, identical with cave alms bowl body 310 row when representing that the young plant in whole seedling dish 300 is exhausted, encoder 241 measured value will reset, variable step liquid damped cylinder 231 stretches out again, until the peg induction end of the second dish seedling dish 300 is sensed by proximity switch 242, variable step liquid damped cylinder 231 shrinks, encoder 241 works again, above-mentioned action will be repeated.
Further, step S40 and step S50 also comprises control system 30 control Ding Miao mechanism 230 respectively, the top seedling masthead of Ding Miao mechanism 230 goes out, after a part of young plant in one row cave alms bowl body 310 is ejected, control system 30 drives synchronizing moving Telescopic-cylinder to drive frame 10 to move, and the top seedling masthead of mechanism of control system 30 control Ding Miao mechanism 230, Ding Miao 230 goes out, another part young plant in one row cave alms bowl body 310 is ejected, the step that the young plant gradation namely in a row cave alms bowl body 310 ejects.Also can eject several times by each row's young plant, such as three times.
When the first row cavities that step S40 also comprises the cave alms bowl body 310 of seedling dish 300 moves to seedling position, top, the slotted opening of the seedling dish limiting plate 251 of the top seedling accessory part 25 of Song Miao mechanism 20 is corresponding with first row cavities, and young plant ejects through slotted opening and first row cavities by the top seedling bar of Ding Miao mechanism 230.
When the next row cavities that step S50 also comprises the cave alms bowl body 310 of seedling dish 300 moves to seedling position, top, the slotted opening of the seedling dish limiting plate 251 of the top seedling accessory part 25 of Song Miao mechanism 20 is corresponding with next row cavities, and young plant ejects through slotted opening and next row cavities by the top seedling bar of Ding Miao mechanism 230.
When young plant in cave alms bowl body 310 ejects by the top seedling bar that step S40 and step S50 also comprises Ding Miao mechanism 230, the multiple seedling dish pressing plates 262 sending the seedling dish of disc mechanism 20 to fix accessory part 26 withstand seedling dish.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
