Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of nonirrigated farmland bare-root seeding transplanters, and which solve in the prior art
The problem of transplanter is limited by narrow slit and influences the transplanting efficiency of seedling.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of nonirrigated farmland bare-root seeding transplanter, including rack, rack-mounted controller and be mounted on the rack from front to back

It connects, third sprocket wheel and the 4th sprocket wheel are connected by the second chain drive, are fixed with seedling clamp device on the second chain, the seedling clamps
It sets including being fixed on the second chain upper support bar, be hinged two clamping plates being arranged symmetrically about support rod on the support rod,
In pressure sensor is installed on a clamping plate inner sidewall, the separate end of two clamping plates is hinged with connecting plate, two connecting plates
Two clamping plates are arranged in close to the end of the second chain, two one end of connecting plate far from clamping plate by with support rod phase
Parallel connecting shaft is hinged, and is equipped with the cylinder flexible towards connection axis direction on support rod between the second chain and clamping plate,
The cylinder body of cylinder is fixed on support rod, and the piston rod of cylinder and connecting shaft are connected, on support rod in the second chain and cylinder it
Between be fixed with the guide rod extended towards connection axis direction, offer the pilot hole being slidably matched with guide rod, institute in connecting shaft
It states to be equipped in rack and be clamped when support rod moves to the second chain front and support rod is in a horizontal position for detecting seedling
The first sensor set and when support rod moves to when the second chain least significant end is in vertical position for detecting seedling clamp device
Second sensor, the pressure sensor, cylinder, first sensor are connected with second sensor Method of Averaging Controller.
Cushion is respectively and fixedly provided on the inner sidewall of described two clamping plates.
The clamping plate and support rod are hinged by hinge.
The connecting plate and clamping plate are hinged by hinge.
The connecting plate and connecting shaft are hinged by hinge.
The present invention takes measures from seedling launching mechanism, and two clamping plates and two connecting plates constitute four-bar linkage structures, by the
One sensor and second sensor detect the position of seedling launching mechanism, when support rod moves in front of the second chain and at support rod
When horizontal position, first sensor detects seedling clamp device and signal is transmitted to controller, and controller controls the piston of cylinder
Bar extends and then drives connection mobile axially away from support rod direction, and connecting shaft drives two clamping plates to revolve to centre by connecting plate
It rotates into and clamps seedling, and control the chucking power of two clamping plates by pressure sensor, when the chucking power of two clamping plates reaches
When certain value, signal is transmitted to controller by pressure sensor, and the piston rod that controller controls cylinder stops elongation, at this time two folders
The chucking power of plate will not press from both sides bad seedling, while seedling will not be fallen from two clamping plates, substantially increase transplantation of seedlings quality and efficiency,
When support rod, which moves to the second chain least significant end, is in vertical position, second sensor detects seedling clamp device and passes signal
To controller, the piston rod of controller control cylinder retracts and then drives connection mobile axially adjacent to support rod direction, connecting shaft
Drive two clamping plates to two sides Unscrew by Miao Songkai by connecting plate, seedling root is placed in ditch at this time, while earthing town
Pinch roller suppression of soil makes seedling stand on ground, completes transplanting work.The present apparatus eliminates narrow slit structure, fundamentally solves
The drawbacks of gap of slit is unable to adjust and brings, the present apparatus can adjust the distance of two clamping plates according to the size of seedling and then will
Seedling is clamped, while avoiding pressing from both sides bad seedling, substantially increases the quality and efficiency of transplantation of seedlings, is that transplanter develops towards automation direction
It creates condition.
