Abstract
The utility model discloses a packing auger crank arm of a cutting machine cutting bed, which comprises a crank arm body, the crank arm body is a rectangular structure with connecting through holes formed in the two ends, clearance adjusting grooves are formed between the connecting through holes and the two longitudinal end surfaces of the crank arm body respectively, cross holes vertically running through with the connecting through holes are formed in the two longitudinal ends of the crank arm body respectively, one end of the packing auger supporting shaft and one end of the extendable gear shaft penetrate relevant connecting through holes respectively, the connecting bolt penetrates the connecting through holes corresponding to the crank arm, one end of the packing auger supporting shaft and one end of the extendable gear shaft respectively and connects one end of the packing auger supporting shaft or one end of the extendable gear shaft fixedly with the crank arm through nuts respectively. The crank arm provided by the utility model is convenient to process, low in manufacturing cost; and the clearance adjusting grooves formed in the two ends of the crank arm form a flexible structure, the crank arm can be prevented from moving through the fixing of the connecting bolt and nut, the service life is prolonged, the cutting machine cutting bed packing auger fault is decreased greatly, and the operation efficiency is improved.
Description
Technical field
The utility model relates to a kind of ceding of Taiwan auger of grain header, especially a kind of while and harvester header auger back shaft and the radius bar that the expansion teeth axle is connected, belongs to agricultural machinery technological field.
Background technology
The auger cylinder of grain header is installed on the ceding of Taiwan body, and under the driving of power set, the auger cylinder is around its axle center rotation, by the rotation propelling harvesting crop of packing auger blade.The auger cylinder is provided with the expansion teeth device, by the expansion teeth device crop of gathering in the ceding of Taiwan is dialled in the delivery chute feeding mouth, the expansion teeth device comprises expansion teeth axle and several expansion teeth, expansion teeth is connected with the expansion teeth axle by flexible toothholder, fixedly connected with radius bar one end respectively in expansion teeth axle two ends, the radius bar other end is fixedlyed connected with the back shaft at auger cylinder two ends respectively, and like this, the back shaft at auger cylinder two ends, expansion teeth axle and two radius bars constitute the crank throw structure.The back shaft at auger cylinder two ends is coaxial with the auger cylinder, there are certain offset in expansion teeth axis and auger cylinder axis, when the auger cylinder rotates around its axle center, the expansion teeth axis keeps relative static with the auger cylinder axis, several expansion teeth one ends stretch out from auger roll circumference hand-deliver mistake respectively, under the promotion of ceding of Taiwan auger cylinder rotation, expansion teeth stretches out in different positions and withdraws and can prevent the band grass, thereby effectively the harvesting crop in the ceding of Taiwan is dialled in the delivery chute feeding mouth.
As shown in Figure 1, existing radius bar 1 is the dumbbell shape structure, processing difficulties, the manufacturing cost height, fixedlying connected by connecting bolt 4, nut 5 with auger cylinder two end supports axle 2, expansion teeth axle 3 respectively in radius bar 1 two ends, is connected for matched in clearance between back shaft 2,1 liang of stomidium of expansion teeth axle 3 and radius bar.Owing to there is foozle, cause the gap between back shaft 2, expansion teeth axle 3 and the radius bar 1 two ends connecting hole 11 at auger cylinder two ends to reach 0.1mm～0.15mm, and this gap can't regulate, make radius bar 1 easy play, finally cause radius bar 1 fracture, influence peasant household and normally gather in.
Summary of the invention
The purpose of this utility model provides a kind of easy processing, low cost of manufacture, long service life, can prevent effectively that radius bar from producing the harvester header auger radius bar of play.
The utility model is achieved by the following technical programs:
A kind of harvester header auger radius bar, comprise the connecting lever body, described connecting lever body is the rectangular structure that two ends are respectively equipped with connecting through hole, described connecting through hole respectively and have the gap adjustment groove that connects connecting through hole between the end face of the vertical two ends of connecting lever body, the vertical two ends of connecting lever body also are respectively equipped with the vertical cross-drilled hole that passes through mutually with connecting through hole, auger back shaft one end and expansion teeth axle one end pass corresponding connecting through hole respectively, connecting bolt crosses the cross-drilled hole of connecting lever body respectively, auger back shaft one end or expansion teeth axle one end, and by nut auger back shaft one end or expansion teeth axle one end are fixedlyed connected with the connecting lever body respectively respectively.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid harvester header auger radius bar, wherein said gap adjustment well width a is 3mm～4mm.
The utility model adopts rectangular structure, easy to process, low cost of manufacture, the gap adjustment groove that open at connecting lever body two ends has formed elastic construction, fastening by the connecting bolt nut, regulate the gap between radius bar connecting hole and auger cylinder back shaft or the expansion teeth axle effectively, thereby prevent that radius bar from producing play, radius bar is easy fracture not, has prolonged its service life, significantly reduce harvester header auger fault, improved operating efficiency.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of existing harvester header auger radius bar;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is the vertical view of Fig. 3.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 3, Figure 4, the connecting lever body 6 of rectangular structure of the present utility model, easy to process; Connecting lever body 6 two ends are respectively equipped with connecting through hole 61, connecting through hole 61 respectively and have the gap adjustment groove 62 that connects connecting through hole 61 between connecting lever body 6 vertical two ends end faces, make connecting lever body 6 two ends form elastic construction, be convenient to regulate the gap between radius bar connecting hole 61 and auger cylinder back shaft 2 or the expansion teeth axle 3, gap adjustment groove 62 width a are 3mm～4mm, and a is 4mm in the present embodiment.Connecting lever body 6 vertical two ends also are respectively equipped with and the connecting through hole 61 vertical cross through hole that pass through mutually 63, connecting bolt 7 crosses cross-drilled hole 63, auger back shaft 2 one ends or expansion teeth axle 3 one ends of connecting lever body 6 respectively, and by nut 8 auger back shaft 2 one ends or expansion teeth axle 3 one ends is fixedlyed connected with connecting lever body 6 respectively respectively.The tightness that connecting bolt 7 is connected with nut 8 has directly been determined auger cylinder back shaft 2 or expansion teeth axle 3 and gap length connecting through hole 61.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
