Description
Technical field
The utility model relates to a kind of agriculture transplanters, and in particular to a kind of nonirrigated farmland bare-root seeding transplanter.
Background technique
With the development of society, agrotechnical raising and progress, many crops and vegetables all with culturing and transplanting seedlings this
One technology is nervous to alleviate crops for rotation, and the tight task heavy work intensity of crop transplanting time is big, it is necessary to could be complete in time with transplanting machine
At crops transplantation technique is a kind of important planting technique for improving crop yield and quality, is gradually making plant setting neck in recent years
Domain is risen, deep to be welcome by vast farmers and agro-technician.Transplanting machine is divided into bare-root seeding and non-bare-root seeding transplanting machine
Not, bare-root seeding transplanter therein is again to save the transplanting such as nutritive cube material, reduce planting cost, be conducive to mentioning for crop quality
The advantages that high, and welcome by agriculture section personnel and peasant.Existing nonirrigated farmland bare-root seeding transplanter common are chain-clip type and flexibility circle
Two kinds of disc type, wherein chain-clip type bare-root seeding transplanter is more common at home, and this chain-clip type bare-root seeding transplanter is actually being answered
Used time needs people to be sitting on planting machine, naked seedling is placed among chain folder by hand, chain folder constantly moves, in the inlet chain folder of slit
Stepped up by slit pressure, naked seedling is sandwiched in wherein to prevent therefrom sliding in advance, and the other end that seedling is clipped in slit is walked out, and seedling folder opens
Seedling is embedded in the ditch held successfully by soil simultaneously, completes plant process.Narrow slit plays an important role on this device, determines chain folder
When step up when to unclamp, and in actual production, seedling it is not of uniform size, but the gap of slit is unable to adjust, when it is some compared with
Big seedling by probably because narrow slit is relatively small to press from both sides bad seedling, be likely to when some lesser seedlings pass through narrow slit when narrow slit because
For narrow slit is relatively large and can't clip seedling, causes seedling to fall off in transportational process and influence to transplant, needs manually to plant seedlings again, influence to move
The efficiency of seedling is planted, so the design and production of narrow slit seem critically important, the bottleneck that narrow slit also develops at this transplanter technology,
Constrain the promotion of transplanter Planting effect and planting speed.

A land wheel 4 is rotatablely installed on the rack by first rotating shaft 5, the first sprocket wheel 6 is fixed in first rotating shaft 5, front end of rack is fixed
There is the mounting plate 7 for connecting with tractor, is equipped with seedling launching mechanism between plough and suppression of soil wheel in rack, throws seedling dress
It sets including being rotatably installed in rack by the second shaft 8 rotational installation the second sprocket wheel 9 on the rack and by third shaft 10
On third sprocket wheel 11, first rotating shaft 5, the second shaft 8 and third shaft 10 be arranged in parallel, first rotating shaft 5,8 and of the second shaft
Third shaft 10 respectively by bearing rotational installation on the rack, corresponding with third sprocket wheel the is fixed in the second shaft 8
Four sprocket wheels 12, the first sprocket wheel 6 and the second sprocket wheel 9 are sequentially connected by the first chain 13, and third sprocket wheel 11 and the 4th sprocket wheel 12 are logical
The transmission connection of the second chain 14 is crossed, the 4th sprocket wheel 12 is identical as 6 outer diameter of the first sprocket wheel, 11 outer diameter of the second sprocket wheel 9 and third sprocket wheel
It is identical, so that the movement velocity of seedling clamp device and transplanter forward speed are equal in magnitude, it is contrary, realize zero-speed plant.The
It is fixed with seedling clamp device on two chains 14, seedling clamp device includes being fixed on the second chain upper support bar 15, is hinged two on support rod
A clamping plate 16 being arranged symmetrically about support rod is equipped with pressure sensor 17, pressure sensing on one of clamping plate inner sidewall
Device and controller control connect, and the separate end of two clamping plates is hinged with connecting plate 18, and two connecting plates are arranged in two
Clamping plate is hinged close to the end of the second chain, the one end of two connecting plates far from clamping plate by connecting shaft 19, connecting shaft 19 and branch
Strut 15 is arranged in parallel, and connecting shaft 19 is extended a distance into close to one end of the second chain towards the second chain direction, two folders
Plate and two connecting plates constitute four-bar linkage structure.Cylinder 20, cylinder are installed between the second chain and clamping plate on support rod 15
Cylinder body be fixed on support rod, the piston rod of cylinder and connecting shaft 19 are connected, on support rod 15 in the second chain and cylinder it
Between be fixed with the guide rod 21 extended towards connection axis direction, offer the pilot hole being slidably matched with guide rod in connecting shaft,
Telescopic-cylinder can drive connecting shaft 19 to move back and forth, and connecting shaft 19 drives two jaws closes or opening by two connecting plates.
