Description
Technical field
The utility model relates to a kind of double-acting cylinder link gear that is used for hole seedling transplanting machine clamper, can be used for the cylinder action link gear of various seed transplanting machine clampers.
Background technology
At present, the clamper gripping seed of cave dish seed implanted device generally adopts folder to refer to that the mode of embracing the seed root realizes.Clamper is driven by belt and moves down, and refers to be inserted in the soil thereby will press from both sides, and then, again by driven by motor, the folder finger ends is inwardly drawn in, and the seed root is clamped, and is driven by belt to move up again, thereby the seed gripping is gone out the cave dish.This structure adopts motor and belt to drive, because the running precision of motor and belt can't strict guarantee, cause the folder cave that refers to damage to coil easily, or chucking power is too big, presss from both sides the seed root soil broken and can't finish gripping work.
Also have the link gear of the clamper of a kind of cave dish seed implanted device at present, moving up and down of clamper adopts the driven by motor belt to realize that the gripping seed then adopts cylinder to realize.Belt drives clamper and moves up and down.When belt drove clamper arrival specified altitude assignment, cylinder piston rod stretched out, and push pointer is inserted in the soil, drove clamper by belt again and moved up, thereby seed is taken out.This structure precision is a kind ofly compared highly slightly with preceding, but still has motor and belt in whole clamping device, so precision still can't strict guarantee.
The utility model content
The technical problems to be solved in the utility model provides a kind of cave dish seed implanted device clamper link gear of being realized by pneumatic structure fully, and this mechanism is not only simple and reliable for structure, and is easy to control, and has higher kinematic accuracy.
For achieving the above object, the utility model has been taked following technical scheme.This mechanism comprises big cylinder fixed mount, big cylinder, cylinder connecting plate, stingy cylinder slideway, small cylinder fixed block, little cylinder and clamper.Wherein: big cylinder is fixed on the big cylinder fixed mount, and big cylinder piston rod and cylinder connecting plate are connected; Little cylinder and small cylinder fixed block are fixed together, and small cylinder fixed block can move up and down along stingy cylinder slideway, and stingy cylinder slideway is static with respect to big cylinder fixed mount.The bottom of little cylinder is passed the cylinder connecting plate and is connected by flange and clamper, thereby cylinder connecting plate, little cylinder, clamper three are fixed together.Folder refers to be placed in the clamper, and is connected with the small cylinder piston bar, and the upper end that folder refers to is fixed in folder and is referred on the frame that the hole of clamp base is passed in the lower end, and the pitch-row of clamp base refers to spacing less than folder, so that after folder refers to pass the hole of bottom, form certain gradient.
The fixed form of cylinder can be set according to concrete structure, and the size of cylinder can be selected according to the concrete stroke of clamper, the spacing between the cylinder, and promptly the length of cylinder connecting plate can be provided with according to integrally-built size.
The number that folder refers to can be selected according to the requirement of physical dimension, and it chooses scope is 2～4; Accordingly, the hole of clamp base also can be provided with according to the quantity that folder refers to, but the spacing of the spacing between the adjacent holes between needing to refer to less than folder.
The present invention adopts same source of the gas as power source, and it is flexible that lifting of adopting two cylinders to link to finish clamper and folder refer to, so simple and reliable for structure, adopt single power source, do not need power-equipments such as motor, greatly reduced and controlled cost, and had higher kinematic accuracy.

Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As Fig. 1～shown in Figure 3, present embodiment comprises big cylinder fixed mount 1, big cylinder 2, cylinder connecting plate 3, stingy cylinder slideway 4, small cylinder fixed block 5, stingy cylinder 6 and clamper 7.Big cylinder 2 is fixed on the big cylinder fixed mount 1 by screw, and the countersunk head screwed hole 17 that big cylinder piston rod 9 passes cylinder connecting plate 3 is fixed together with cylinder connecting plate 3 by first flange 10.Stingy cylinder 6 is fixed together by screw and small cylinder fixed block 5, and small cylinder fixed block 5 can move up and down along stingy cylinder slideway 4, and stingy cylinder slideway 4 is static with respect to big cylinder fixed mount 1.The hex hole 18 that cylinder connecting plate 3 is passed in the bottom of stingy cylinder 6 is fixed together with clamper 7 by second flange 12, thereby cylinder connecting plate 3, stingy cylinder 6, clamper 7 threes are fixed together.Folder refers to that frame 13 places in the clamper 7, and small cylinder piston bar 15 refers to that with folder frame 13 is fixed together by the 3rd flange 14.Folder refers to that 16 upper end is fixed in folder and refers on the frame 13, thereby the lower end is passed the hole of clamper 7 bottoms and finished gripping work.The pitch-row of clamp base refers to spacing less than folder, so that after folder refers to pass the hole of bottom, forms certain gradient, has certain clamping force and don't broken as for soil is pressed from both sides to guarantee to press from both sides after referring to be inserted in the soil.
As shown in Figure 1, big cylinder 2 is fixed on the big cylinder fixed mount 1, and big cylinder 2 is in not duty, and big cylinder piston rod 9 is fully in big cylinder 2.Cylinder connecting plate 3 is fixed together with big cylinder piston rod 9.Stingy cylinder 6 is fixed together with small cylinder fixed block 5, and small cylinder fixed block 5 can move up and down along stingy cylinder slideway 4.Stingy cylinder 6 is in not duty, and small cylinder piston bar 15 is fully in stingy cylinder 6.Cylinder connecting plate 3, clamper 7 are fixed together by second flange 12 with stingy cylinder 6, and the clamper folder refers to that major part places in the clamper 7, is in the state of not stretching out.
As shown in Figure 2, big cylinder 2 is started working, big cylinder piston rod 9 stretches out, promoting cylinder connecting plate 3 moves downward, cylinder connecting plate 3 drives stingy cylinder 6 and small cylinder fixed block 5 moves downward along stingy cylinder slideway 4, and promote clamper 7 and move downward, after motion stops, clamper is remained on certain height.
As shown in Figure 3, big cylinder piston rod 9 motions stop, stingy cylinder 6 is started working, small cylinder piston bar 15 stretches out outside the stingy cylinder 6, and the folder that promotes within the clamper 7 refers to that frame 13 moves downward, folder refers to that frame 13 promotes folder and refers to that 16 holes of passing clamper 7 bottoms move downward, because the pitch-row of clamper 7 bottoms refers to spacing less than folder, therefore, refer to 16 when moving downward at folder, the folder finger-type that reaches outside the clamper 7 has a certain degree, when being inserted in the soil, have certain clamping force, and don't broken as for soil is pressed from both sides, thus the seedling work of getting finished well.
As shown in Figure 4, an end of cylinder connecting plate 3 has countersunk head screwed hole 17, is fixed together by first flange 10 and big cylinder piston rod 9; The other end has hex hole 18, and stingy cylinder 6 bottoms are passed hex hole 18 and are fixed together by second flange 12 with clamper 7, and cylinder connecting plate 3, stingy cylinder 6, clamper 7 threes are moved simultaneously.
Because transmission realizes based on strength in the motion of said mechanism, each part running precision is higher, and requirement according to concrete work, also can adjust structure comparatively easily, and when work, only need control two cylinders and can satisfy job requirement accurately, therefore, control is got up very simple, because two cylinders can adopt same source of the gas, so can greatly reduce cost.
The utility model is not limited to above-mentioned embodiment, no matter do any variation and adjustment on part shape, quantity or structure, everyly utilizes two cylinders to link to realize clamper work, all falls within the utility model protection domain.
