The automatic seedling taking device carrying out practically process of transplanter of the present utility model is as follows：

First, the dynamical system of transplanter drives the sprocket wheel of drive mechanism to rotate clockwise, and sprocket wheel is fixed on so as to drive On sprocket shaft rotate, sprocket shaft is further rotated case and rotates clockwise together --- due to the sun inside gear-box Wheel is connect disk by dental inlay and engaged, therefore sun gear carries out the rotation counterclockwise relative to rotary box in rotary box, while band Dynamic breast wheel, planetary gear, it is final to drive planet wheel spindle to be rotated relative to rotary box.Because twist mechanism and planet wheel spindle are engagings , the translating cam of twist mechanism and the rotation cam of seedling taking arm body are engagings, therefore during planet wheel spindle rotation, understand band in the lump Dynamic twist mechanism and seedling taking arm body are rotated.

When rotary box is rotated, the position for referring to pincers also rotates with it and run along track, when the end for referring to pincers runs to seedling Disk nearby when, the rotation of planet wheel spindle drives working face of the outer roller along external cam on pivoted arm to climb to upper working face so that Driving the finger pincers of clamping device to stretch into the native pot seedling of hole and clamping band of seed plate by pivoted arm, (outer roller works in external cam During face (on boss), refer to pincers action to stretch out and clamping, i.e., seedling taking is acted), and drive pot seedling to depart from seed plate.

Following outer roller continues to roll on the upper working face of external cam, and the internal trolley on twist mechanism also begins to edge The working face of cam ring is climbed upwards by minimum point, promotes translating cam along planet wheel spindle upward sliding (that is, to away from gear-box Slide in the direction of body).When translating cam is slided axially upward, rotation cam can be pushed, and rotation cam is stopped nothing by block Method is moved up further.Due to having an inclined-plane at the engaging of translating cam and rotation cam, therefore, when rotation cam is pushed up, The ramp effect of translating cam is in rotation cam inclined-plane so that the slip of translating cam is converted to the rotation of rotation cam, so that So that seedling taking arm integrally can also be rotated counterclockwise around planet wheel spindle, refer to band of the pot seedling clamped by pincers top in this rotational action It is able to adjust attitude under dynamic, forms erectility.

As the sprocket wheel of drive mechanism continues to rotate clockwise, extreme lower position is run to when referring to pot seedling of the pincers together with extraction When, outer roller will be dropped down from the upper working face of external cam, so as to drive clamping device retraction to refer to pincers release by pivoted arm Pot seedling (can unclamp) in the lump when referring to pincers retraction, complete to throw seedling action.Following working face of the internal trolley along cam ring is by peak Operation downwards, resetting-mechanism drives rotation cam and translating cam to rotate and mobile, and seedling taking arm turns clockwise around planetary gear shaft Dynamic return.

Hereafter, as the sprocket wheel of drive mechanism continues to rotate clockwise, refer to pincers and enter the next circulation of backhaul progress.Rotation The seedling taking arm alternation at case two ends, both improves operating efficiency, the mass distribution of pivoting part is balanced again, so as to run more Steadily.

In addition, the position of seed plate, throwing seedling position, the set location of transplanter, size etc., those skilled in the art can root Factually the situation on border is adjusted, and seedling taking action is carried out in seed plate as long as enabling and referring to when pincers stretch out, and can be aligned in retraction Throw seedling position.

A kind of automatic seedling taking device for transplanter that the utility model is provided, it is adaptable to the band cultivated in hole plate seedling growth mode Native pot seedling as manipulating object automatic transplanter seedling taking and throw seedling.Compared with prior art, transplanter of the present utility model Automatic seedling taking device, can reach following significant technique effect：

1) automatic seedling taking device of the present utility model can be conveniently mounted to move as the individual operating components of transplanter On the whole machine of cultivation machine, the automation of transplanter is realized, labour is liberated, efficiency is improved.

2) the finger pincers of automatic seedling taking device of the present utility model can be run, close on time and be opened by intended trajectory and sensing Open, capture and deliver exactly individual plant pot seedling from hole tray, small, seedling taking efficiency high, it is adaptable to automatic transplanter is damaged to pot seedling Seedling taking and throwing seedling.
