Description
Technical field
The utility model belongs to tobacco field planting field more particularly to a kind of tobacco planting film breaking unit.
Background technique
In the operation of existing tobacco planting, annual 3-4 month can to the tobacco seedlings after floating seedlings from seedling growth greenhouse transplant to
On the cigarette ridge of crop field, then the laying plastic on cigarette ridge carries out the protection of early growth to it to carry out heat and moisture preserving to tobacco seedlings,
Grow with the growth of tobacco seedlings and increase variation with extraneous seasonal temperature, needs to break the mulch at the top of tobacco seedlings, so that cigarette
The blade of seedling can be exposed to the external world through the mulch place of breaking, and then carry out ridging to the mulch on tobacco seedlings root periphery again and cover
Realize the heat preservation to its root.
In the prior art, more traditional mode is using manually rupture of membranes, i.e. cigarette agricultural hand are scratched at the top of rotten tobacco seedlings
Mulch, although this mode will not damage tobacco seedlings, inefficiency and labor intensity is larger；Certainly there are also
Tool can scratch mulch, to realize rupture of membranes operation, the mulch compression device as disclosed in Publication No. CN102440161A,
A kind of telescopic flue-cured tobacco mulch membrane-repturing device disclosed in Publication No. CN207519296U etc. is using the open cylindrical shape in bottom to cigarette
Mulch above seedling is cut, while simultaneously being shrouded tobacco seedlings in rupture of membranes and being protected；Or it is other using pointed blades
The device of mulch is scratched, although work efficiency is high for these two types of devices, is existed as following drawbacks:
1) device for using sleeve-like configuration rupture of membranes, although tobacco seedlings shroud can be protected tobacco seedlings not while rupture of membranes
It is scratched, but it cuts off that formula damage area is excessive to mulch, i.e., falls the plastic film cutter above tobacco seedlings, this meeting is so that tobacco seedlings
Soil at root loses the protection of mulch and is completely exposed to the external world, is unfavorable for the heat preservation of cigarette strain root；
2) mulch is scratched using pointed blades, though formula injury is not cut off to mulch generation, due to blade sharp portion court
To mulch operation, the phenomenon that scratching the tobacco seedlings below mulch together can largely occur.
Utility model content
The purpose of the utility model is to provide a kind of tobacco planting film breaking unit, the utility model can to mulch into
On the basis of row rupture of membranes, the injury to tobacco seedlings is greatly lowered, and only scratch without cutting off to mulch, so that mulch still is able to
Tobacco seedlings root is coated to carry out ridging heat retaining operation.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:
A kind of tobacco planting film breaking unit, described device include the inside and outside cylinder being coaxially arranged, and inner cylinder top is located at outer
Boundary, inner cylinder bottom interior wall are circumferentially equidistantly set there are four the supporting plate being radially extending, diameter on the inner cylinder inner wall below each supporting plate
To body cradle is equipped with, pin shaft is hinged at the top of body cradle and the blade knife spine for being located at body cradle middle, at the top of the blade part of blade
It is connect by the first spring constantly in the state that is stretched with bracket end, the blade is in upward and whole compared with short right-angle side
The right angled triangle being vertically arranged, the bevel edge of blade are blade part and are arranged towards inner cylinder inner wall that the relatively long right-angle side of blade is
Knife spine portion, the pin shaft hinged place of blade and with the first spring junction close to compared with short right-angle side setting blade knife spine portion one
Packet is equipped with layer of silica gel, and layer of silica gel extends to blade bottom end；The inner cylinder bottom end is offered to be lacked with the first of gap blade cooperation
Mouthful.
Preferably, the outer tube inner wall corresponds to the first indentation, there of inner cylinder equipped with axially extending slot of returning sword, outer cylinder bottom end
Corresponding first indentation, there is additionally provided with the second notch, returns sword slot and the second notch and blades fit.
Preferably, the inner cylinder top is equipped with top plate, and outer cylinder top is radially provided with flange, and flange is equipped with through-hole, pull rod
Top is vertical with top board undersurface after through-hole to be connect, and is arranged with second spring, pull rod on the pull rod body of rod between flange and top plate
Bottom end is vertically connected with handle, and handle is located at setting below flange.
Preferably, the outer cylinder bottom outer wall axial symmetry is vertically connected with support plate, support plate bottom surface and telescopic sleeving rod
Inner rod vertically connects, and the outer tube of telescopic sleeving rod is vertical with wheel shaft one end to be connect, and the wheel shaft other end is connected by bearing and idler wheel
It connects.
Preferably, the telescopic sleeving rod outer cover is equipped with third spring, and third spring top connects support plate, bottom connection
Axle shaft.
Utility model works principle is as follows:
The utility model is moved at the cigarette ridge of laying plastic by two idler wheels first, and two idler wheels is made to be located at cigarette ridge
Inside and outside cylinder is placed in above mulch, then moves the utility model along cigarette ridge by two sides, when inside and outside cylinder be moved to tobacco seedlings just on
Fang Shi so that outer cylinder moves down and crimp mulch, and keeps the shape at the subsequent process moment by overcoming the elastic force of third spring
State；
Pull rod is pulled by handle this moment, so that inner cylinder overcomes the elastic force of second spring and axially moves down with respect to outer cylinder, with
Moving down for inner cylinder, four blades gradually come out from outer cylinder bottom-exposed, the drawing due to four blade moment by the first spring
It is dynamic, so four blade moment keep the trend backwards to rotation, so when four blades are exposed from outer cylinder bottom end, bottom
The layer of silica gel at end can pull mulch in four direction crimping and mulch is pullled out cut by frictional force, since the outer cylinder moment presses
Ground film, so four blades can enter mulch from cut.And as the opposite of inner cylinder moves down operation, blade gradually rotate and
Its blade can be removed from the first, second indentation, there in inner barrel and outer barrel.
Blade rotation and after being moved to extraneous certain length, no longer holding outer cylinder crimping ground membrane stage, outer cylinder is in third bullet
Spring effect is lower to be resetted, and is moved up with cutting blade, due to the state of blade this moment in blade upward, so blade is during moving up
Mulch can be marked strip cut, mulch can be cut out the cross edge of a knife by four blades, then release handle, so that the second bullet
Spring drives inner cylinder to move up reset with respect to outer cylinder, and four blade opposite directions are collapsed formula retraction outer barrel.Blade and outer tube inner wall
On slot cooperation of returning sword, and slot of returning sword can be to the entire mobile progress direction limit of blade.In the above process, blade meeting and cigarette
Seedling generates contact, but only the layer of silica gel of knife spine is contacted with tobacco seedlings, will not generate scuffing to tobacco seedlings.
Cut out the mulch of the cross edge of a knife, it is sufficient to so that the tobacco leaf of tobacco seedlings is exposed to the external world, although and mulch rupture,
It is not cut off, the later period can still stick on when earthing up participates in heat retaining operation above cigarette strain root.
The utility model compared with prior art, has the advantages that the utility model can carry out rupture of membranes to mulch
On the basis of, the injury to tobacco seedlings is greatly lowered, and only scratch without cutting off to mulch, so that mulch still is able to cladding cigarette
Seedling root is to carry out ridging heat retaining operation.
