Abstract
The utility model relates to a seedling-picking weed-pulling device which comprises a vertical rod. A shearing type weed clamping mechanism is arranged at the lower end of the vertical rod. A handle and a poking rod controlling the shearing weed clamping mechanism to rotate are arranged at the upper end of the vertical rod. The seedling-picking weed-pulling device utilizes the shearing type weed clamping mechanism with the concave-convex matching face and utilizes the matching effect of a spring and a pull thread. Pull thread control adopts the control mode similar to that of a brake line. The seedling-picking weed-pulling device is reasonable in structure, durable in use and good in effect. The tool for seedling picking and weed pulling brings great convenience to workers who do not need to bend over to pick seedling and pull weed, is high in weed pulling efficiency, saves time and labor, and is simple in structure, low in processing cost and suitable for batch production, popularization and application.
Description
Technical field:
The utility model belongs to a kind of weeder of farm machinery, is specifically related to a kind of seedling extirpator that picks.
Background technology:
Farmland seedlings of cereal crops seedling need be removed weeds around it period, promptly picks the seedling uprooting weed, otherwise can cross the prosperous seedlings of cereal crops normal growth that influences because of weeds.Weeds follow the seedlings of cereal crops to grow together, and this weeding system needs fine processing, otherwise can cause the destruction to the seedlings of cereal crops.Also do not have at present the special-purpose seedling weeding instrument that picks, existing weeding instrument only is suitable for the weeding of extensive meadow or cuts grass, all is not suitable for and picks the seedling uprooting weed.Pick the seedling uprooting weed at present and still continue to use the traditional hand mode, pick by hand the seedling back of the body of must bending over to collude, very tired, and weeding ratio is very low.Usually, the big and weeds limited amount of seedlings of cereal crops spacing if take manual weeding to exist to bend over uprooting weed frequently to hocket with walking upright, is the work that a kind of ten minutes is worked hard.In mechanization degree increasingly high today, picking the seedling uprooting weed also should have corresponding instrument.
Summary of the invention:
The utility model still exists backward in technique and does not have the problem of aid to picking the seedling uprooting weed in the prior art, provide a kind of simple in structure, easy to use, effective, efficient is high picks the seedling extirpator.
Technical scheme: a kind of seedling extirpator that picks, comprise a montant, the montant lower end is provided with scissors grass-trap mechanism, the upper end is provided with handle and controls the driving lever that scissors grass-trap mechanism rotates.
Said scissors grass-trap mechanism comprises two forks that are superimposed, and each fork includes anterior chuck, the axis hole at middle part and the cantilever at rear portion, is sleeved on the montant lower end after the axis hole at two forks middle part is superimposed; Be provided with between two cantilevers and hold out against spring, be connected with backguy on two cantilevers respectively, be connected an end of driving lever after two backguys converge.
The convex-concave mating surface is set on the inwall of two chucks.
At the fixing support bar under being tilted to of the rear side of said montant, the end of this support bar is positioned at two cantilever centre positions, and this support bar end is provided with pilot hole or directive wheel or guide post (hook) and is used for two side guys are positioned.
Be provided with the backguy outer tube along montant and support bar, outer tube one end is fixed on montant top, the other end is fixed on the support bar, and said backguy is positioned at this outer tube.
Can also fix a push rod in the montant upper end, the height of push rod is higher than said driving lever, and an end of said outer tube is fixed on this push rod.
Montant is set to fixable stretching structure, comprises the inner and outer pipe that connects together each other, and at the outer tube arranged outside bolt of screwing.
The beneficial effect of the utility model:
The scissors grass-trap mechanism of the utility model utilization band convex-concave mating surface can uproop grass or crops, and utilize the mating reaction of spring and backguy, and the control mode that is similar to the brake line is adopted in backguy control, and is rational in infrastructure, durable, effective.
The instrument that picks the seedling uprooting weed that the utility model provides brings great convenience for labourer, uses this instrument to need not to bend over to collude to pick the seedling uprooting weed privately, and uprooting weed efficient is high, and is time saving and energy saving.And the vertical tube of the utility model can be arranged to can telescopic adjustment structure, the people of being convenient to different heights uses, simple in structure, processing cost is low, is fit to produce in batches and apply.

Fig. 2 is the structural representation of scissors grass-trap mechanism;
Fig. 3 is the side structure sketch map of chuck among Fig. 2;
Fig. 4 is two of the utility model structural representation.
Embodiment:
Embodiment one: referring to Fig. 1, and Fig. 2 and Fig. 3, this picks the seedling extirpator and comprises a montant 1, and montant 1 lower end is as rotating shaft 2, and rotating shaft 2 parts can slightly be narrower than montant.Be set with scissors grass-trap mechanism in this rotating shaft 2; This scissors grass-trap mechanism is formed by stacking two forks; Each fork is formed by the chuck 3 of front portion, the axis hole at middle part and the cantilever 5 at rear portion; The axis hole stack back coupling at two fork middle parts is sleeved in the said rotating shaft 2, thereby two forks can freely rotate formation scissors structure.The fixing support bar 7 under being tilted to of montant 1 rear side, the end of this support bar 7 is positioned at two cantilevers, 5 centre positions, and these support bar 7 ends are provided with pilot hole 8 and are used for two side guys are positioned.Be provided with between two cantilevers 5 and hold out against spring 6, two cantilevers 5 medial surfaces hanging nose 9 is set respectively, be connected with backguy on the hanging nose 9, two backguys converge the back and form a total backguy.Be provided with backguy outer tube 11 along montant and support bar, outer tube 11 1 ends are fixed on montant 1 top, the other end is fixed on the support bar 7, and said backguy 10 is positioned at this outer tube 11.Montant 1 upper end is provided with handle 12; Driving lever is installed in the montant upside through rotating shaft, and the rotating shaft of present embodiment is positioned at the upside of handle 12, and promptly the part of driving lever 13 is positioned at handle 12 upsides; Another part is positioned at handle 12 downsides, and the other end of said wire drawing 10 is connected this driving lever 13 ends.When stirring said driving lever 13, backguy 10 is stretched, and drives two cantilevers 5 and inwardly shrinks, and further drives two chucks 3 and inwardly shrinks.
