Description

Cigarette seedling trimmer

Technical field:

The utility model belongs to agricultural mechanical field, particularly a kind of cigarette seedling trimmer that can carry out trimming blade to cigarette seedling in the pallet.

Background technology:

In the tobacco seedling process, in order to make cigarette seedling stalwartness, need the cigarette seedling of different production cycles is carried out the leaf-cutting processing, it is to adopt manually to finish that tradition is pruned, but efficient is extremely low, and be difficult to control the quality of pruning, at present, have mechanical leaf-cutting equipment, improved production efficiency greatly, and the cigarette seedling of pruning out is neat and standard meets fairly large need of growing seedlings.As, Chinese patent N9923091,4 disclosed be a kind of tobacco seedling dish leaves shearing machine, include frame, be installed in the shear knife mechanism of upper rack, shear knife mechanism is by motor-driven, dynamically be hubbed at the tray rack on the frame, tray rack is supported by two lifting poles, two pole axles are positioned on the frame, and the bolt by a band handle between two poles drives, when can driving two poles, the handle rotation puts and makes the tray rack lifting together, the action of perhaps opening and tray rack being descended, regulate the spacing of cigarette seedling with this, satisfy the need of cigarette seedling the prunings same period not from the shear knife edge of a knife.Because cigarette seedling pallet has certain area, and the tray rack lifting in this equipment relies on the support of two poles, is difficult to held stationary and synchronism.

Summary of the invention:

The purpose of this utility model is a kind of cigarette seedling trimmer by the lifting of single screw drive tray rack of design.

Technical solutions of the utility model are achieved in that a kind of cigarette seedling trimmer, comprise frame, be installed on the frame by power-actuated shear knife, dynamically be hubbed at the hoistable platform on four feets of frame and be installed in carriage on the hoistable platform, it is characterized in that the hoistable platform bottom center is fixed with a longitudinal screw, be connected with a band internal thread bevel gear on the screw rod, this internal thread bevel gear be positioned on the housing bearing seat by bearing and with a trunnion axis that is positioned on the housing bearing seat on the bevel gear engagement, trunnion axis extends to the outer rear flank of frame and is fixed with handwheel.Handwheel is in the frame side, and the handled easily person observes the spacing of the cigarette seedling and the edge of a knife while regulating, and guarantees the quality of pruning, moreover relies on single pole to support, and makes the synchronism of lifting good.

In addition, be fixed with guide runner on the hoistable platform frame, be located on four feets of frame by means of the guide runner slide pivot.Utilize the rail plate of frame support pin, but keep hoistable platform stable equilibrium ground lifting as lifting.

The utlity model has reasonable in design, the manual drives lifting is regulated simple to operate lightly, and hoistable platform and carriage lifting are steady, and synchronism is good, observes while regulating but handwheel is in the frame side.

Embodiment:

See figures.1.and.2, cigarette seedling trimmer includes frame 1, power 2, shear knife 21, hoistable platform 3 and is installed in carriage 4 on the hoistable platform 3.Hoistable platform 3 bottom center are fixed with a longitudinal screw 5, be connected with a band internal thread bevel gear 51 on the screw rod 5, this internal thread bevel gear 51 is positioned on the housing bearing seat 6 by bearing, one trunnion axis 53 is positioned on the frame 1 by other diaxon bearing 6, the one end be fixed with one can with internal thread bevel gear 51 meshed bevel gears 52, the other end extends to frame 1 outer rear flank and is fixed with handwheel 54, is convenient to operation.Owing to adopt the engagement and the internal thread bevel gear of bevel gear set to cooperate with the two-stage of screw rod, not only the operation of handwheel 54 is lighter, and hoistable platform 3 liftings are steady more and accurate, and have the self-marketing effect, hoistable platform 3 need not extra detent mechanism after regulating and putting in place.

With reference to Fig. 1, Fig. 2 and Fig. 3, be fixed with guide runner 31 on hoistable platform 3 frames, be located on 1 four feets 11 of frame by means of guide runner 31 slide pivot.For make guide runner 31 more secure fixation at the narrower frame of hoistable platform 3, in hoistable platform 3 frame solid weldings slide block backing plate 32 with two bolts hole is arranged, utilize slide block backing plate 32 to enlarge the position of positioning and guiding slide block 31, and realize 2 stable fixed structures, offer the long slot bore 33 of 32 liang of bolts hole of corresponding slide block backing plate on the guide runner 31, guide runner 31 is locked on slide block backing plate 32 by two bolts 42.The spacing of utilizing the thickness difference of slide block backing plate 32 can regulate horizontal two guide runners 31, and the spacing of utilizing the long slot bore 33 on the guide runner 31 can regulate vertical two guide runners 31 is adjusted to and 11 of four feets of frame have best slip and are pivoted.

As Fig. 3, because frame adds standard sections such as generally adopting angle steel man-hour and is welded, four feets 11 can be made by angle steel, guide runner 31 offers and the suitable guide groove 34 of feet 11 angle steel side plate thickness for this reason, utilize guide groove 34 dynamically to be embedded on the feet 11 angle steel side plates, also promptly the side plate of four feet angle steel forms four tracks, guarantees the flexibility of hoistable platform 3 oscilaltions.

And for example Fig. 1 and Fig. 2, this structure medium power part is shown in broken lines, all adopts motor at conventional art medium power 2, need in the regional operation that electricity arranged, and the cultivation of cigarette seedling ground often away from the village, specially draws special line, and is uneconomical also dangerous.For this reason, the power that drives shear knife can be gasoline engine, is provided with the fixed standard seat of motor and gasoline engine on frame 1, and the handled easily person changes power.Promptly adopt motor in the operation of electric region territory,, reach the purpose of steam-electric dual purpose, to adapt to the different work environment if non-Electric region in the open air can replace with gasoline engine.

Fig. 2 for another example, carriage 4 is an accordion structure, is made up of main carriage 4 and the secondary carriage 41 that is hinged on main carriage 4 two ends, main carriage 4 and secondary carriage 41 join to locking by bolt 42 respectively on the frame and keep straight.Carriage 4 adopts foldable structure, is convenient to collection, moves and transportation.
