By the re-fixing assembly structure of split members such as the base, the cutter back seats and the reinforcing plates and the like, the technical problem that an existing large-size cutter rack is high in manufacturing difficulty and cost is solved, the integral hay cutting assembly is free of deformation, and excellent cutting efficiency and quality is guaranteed.
Description
Technical field
The utility model relates to hay cutter, in particular hay cutter guillotine cutting cutter-head mechanism.
Background technology
The core of hay cutter is guillotine cutting assembly, and guillotine cutting assembly assembly comprises cutterhead frame, the moving knife on work spindle and the stationary knife coordinating with moving knife guillotine cutting, and stationary knife be arranged on hand hay cutter careless working chamber housing feeding mouth place, on the tool arm of moving knife dead knife plate rail.Guillotine cutting assembly structure and assembling directly impact are cut up with a hay cutter herbaceous stem amount, are cut up with a hay cutter careless efficiency and service life.The guillotine cutting assembly of existing hay cutter, cutterhead frame is that monoblock cast forms, because volume is larger, manufacturing cost is high, quality is also difficult to ensure, output efficiency is low; In addition, the straight-bar tool arm support strength on cutterhead frame is low, and each point discontinuity in work and occur distortion can change the guillotine cutting fit clearance of moving knife and stationary knife, reduction guillotine cutting efficiency and guillotine cutting quality.
Existing guillotine cutting assembly is for improving guillotine cutting stress between chopper, and then raising guillotine cutting efficiency, moving knife has adopted arcuate blade blade, fixing being contained on straight-bar tool arm by bolt multiple spot, moving knife bears guillotine cutting load frequently, middle part arcuate blade more protrudes from straight-bar tool arm linear edge with respect to both sides arcuate blade, the bolt fixed bit at this place is also away from middle part cutting edge, the fit clearance of its cutting edge of adjusting that cannot be consistent and stationary knife, its support that comes from straight-bar tool arm of the local pressure of moving knife is extremely unbalanced, cause moving knife in guillotine cutting, to occur distortion, affect guillotine cutting efficiency and guillotine cutting quality, even can cause the normally phenomenon of guillotine cutting, normal life cycle is short.
Summary of the invention
Goal of the invention of the present utility model is significantly to reduce manufacturing cost, improves integrated support intensity and be easy to regulate and keep lastingly the hand hay cutter grass guillotine cutting assembly of fit clearance between chopper and assemble the hay cutter of this guillotine cutting assembly simultaneously.The hand hay cutter grass guillotine cutting assembly technical scheme that the utility model provides, its main technical content is: the careless guillotine cutting assembly of a kind of hand hay cutter, guillotine cutting assembly assembly comprises the cutterhead frame on work spindle, moving knife is fixed on cutterhead frame, with be fixed on hand hay cutter careless feeding mouth stationary knife guillotine cutting matched in clearance, cutterhead frame is wherein made up of sleeve base and some knife back seats, knife back seat bottom is fixed in sleeve base, stiffener is fixedly installed on the back side of knife back seat and extends in sleeve base, form the homogeneous radiation shape moving knife arm in sleeve base, the moving knife bolt of curved blade is met and is cut side position at knife back seat solid, described meeting cut side position and had the lateral margin identical with moving knife blade arc, bolt and meeting is cut and between side position, is provided with the adjusting jackscrew for regulating moving knife and stationary knife guillotine cutting gap.
In above-mentioned overall technical architecture, described stiffener has with moving knife blade arc to contrary strengthening segment.
The utility model provides a kind of technical scheme of the hay cutter that assembles the careless guillotine cutting assembly of described hand hay cutter.
The technical scheme of the hay cutter of the careless guillotine cutting assembly of the disclosed hand hay cutter of the utility model and this guillotine cutting assembly of assembling, take the split members such as pedestal, knife back seat and stiffener to fix again package assembly, solve existing cutterhead frame because of manufacture difficulty and the high technical problem of cost that volume strengthens greatly, manufacturing cost is significantly reduced; Knife back seat is met and cut lateral margin design and have the arc identical with moving knife, make moving knife entirety blade obtain consistent support guarantee, and can adjust moving knife blade and keep and stationary knife guillotine cutting fit clearance accurately, overall guillotine cutting assembly is indeformable, ensures guillotine cutting efficiency and guillotine cutting quality that it is good.

Fig. 2 is stereogram dorsad of the present utility model.
Fig. 3 is the relative position schematic diagram that shows cutterhead frame and feeding mouth, discharging opening.
Embodiment
The hand hay cutter grass guillotine cutting assembly that the utility model provides and pan feeding portion, driving section and the assembling of working chamber housing form hay cutter.This cuts up with a hay cutter one of careless guillotine cutting assembly and implements structure as shown in drawings, and this guillotine cutting assembly comprises the cutterhead frame 1 with homogeneous radiation shape moving knife arm, it on moving knife 11 successively with the stationary knife guillotine cutting matched in clearance that is fixed on the careless feeding mouth of hand hay cutter, implement efficiently to break hand hay cutter work.
Cutterhead frame 1 is made up of sleeve base 10 and some knife back seats 12, knife back seat 12 bottoms are fixedly mounted in sleeve base 10, stiffener 13 plate faces erect the back side that is fixedly installed on knife back seat 12, and extend in sleeve base 10, have jointly formed the radial moving knife arm in sleeve base 10.Being fixedly preferably between knife back seat 12, stiffener 13 and sleeve base 10 is welded and fixed connection, and its advantage is: each component volume of decomposition is little, and manufacture and fixed combination manufacturing cost reduce greatly, are also easy to ensure product quality.
In this guillotine cutting assembly, adopt the fan-shaped moving knife 11 of curved blade, moving knife 11 is fixed on knife back seat 12 by row's bolt 14 and meets and cut side position, described meeting cut side position and had the lateral margin 120 identical with moving knife blade arc, bolt 14 and meeting is cut between side position lateral margin 120 and is provided with for regulating moving knife 11 and one of stationary knife guillotine cutting gap to tease and ridicule joint jackscrew 15, this knife back seat 12 structures provide consistent support for the overall blade of moving knife 11, guarantee moving knife 11 is worked stressed even, indeformable, also make the jackscrew 15 can be by corresponding the arranging of moving knife 11 arcs, make the guillotine cutting fit clearance that moving knife entirety blade and stationary knife are good, improve guillotine cutting quality and efficiency, this effect is lasting.
In this enforcement structure, the stiffener 13 of its knife back seat 12 has with moving knife blade arc to contrary strengthening segment.As shown in Figure 3, discharging opening is arranged at the dotted line A place in work spindle left side, feeding mouth is arranged at the dotted line B place on work spindle right side, in the clockwise guillotine cutting running of cutterhead frame 1, stiffener 13 arcs are cutterhead frame 1 rotation direction of working dorsad, there is the ability of good anti-running resistance, self and knife back seat 12 all do not produce distortion, particularly stiffener 13 is also on-stream, the wind-power that its plate body produces assists guillotine cutting particle to release discharging opening effectively, in order further to strengthen this pneumatic motive force, make guillotine cutting particle discharge smoothly working chamber housing, stiffener 13 outer ends protrude from knife back seat 12 and form aerofoil 16.
