Only crops are taken away.
The ceding of Taiwan feeding screw feeder of united reaper realizes the feedings of crops by expansion teeth, thus the connection of expansion teeth with
Fixation is exactly the core of feed roller, be fixed as one formula mechanism of the existing expansion teeth on expansion teeth axle, dismounting fiber crops
It is tired, if changing the lower flexible toothholder of some damage it is necessary to which all flexible toothholders, intermediate connecting shaft is pulled down, to assembling,
Many difficulties are brought after sale.The connecting seat of existing expansion teeth and screw feeder periphery is fixed mechanism, and expansion teeth is just by used
Property connecting seat endoporus between whipping back and forth, not only operating noise is big, and parts are easily damaged.
Utility model content
Technical problem to be solved in the utility model is that there is provided one kind maintenance, dress for above-mentioned the deficiencies in the prior art
With convenient, improve the flexible toothholder life-span and reduce the ceding of Taiwan feeding screw feeder expansion teeth of ceding of Taiwan harvesting noise.
The technical solution adopted in the utility model is：A kind of harvester header feeds screw feeder expansion teeth, it is characterised in that bag
Expansion teeth, flexible toothholder, bearing pin, guide pin bushing, guide pin bushing mounting seat, expansion teeth axle and screw feeder roller are included, the flexible toothholder is symmetrically pasted
Conjunction forms axially extending bore and radially installed hole, and one end of flexible toothholder is fixedly connected by bearing pin, and expansion teeth axle is placed in the axle
Into through hole, described expansion teeth one end is fixed in the radially installed hole of flexible toothholder, and the other end stretches out through the guide pin bushing to be stirred
Imperial cylinder surface, the guide pin bushing sets perpendicular to expansion teeth and is fixed on screw feeder cylinder surface by guide pin bushing mounting seat, and guide pin bushing can
What is rotated is arranged in guide pin bushing mounting seat.
Further preferably, the guide pin bushing mounting seat includes setting in the middle of guide pin bushing upper mounting seat and guide pin bushing lower mounting seat, guide pin bushing
There is an annular projection, the middle part of guide pin bushing upper mounting seat and guide pin bushing lower mounting seat is connected with guide pin bushing two ends, guide pin bushing upper mounting seat and guide pin bushing
The two ends laminating of lower mounting seat and it is secured by bolts in screw feeder cylinder surface.
Further preferably, described expansion teeth one end is provided with mounting hole, and expansion teeth is consolidated by the bolt being connected with mounting hole
Due on flexible toothholder.
Further preferably, guide pin bushing and the expansion teeth seat material uses polytetrafluoroethylene (PTFE) or polyamide.
Compared with prior art, the beneficial effects of the utility model are：To fixed form of the expansion teeth on expansion teeth axle
Split-type structural is changed to, individually changeing for flexible toothholder can be achieved, assembling, maintenance time is greatlyd save, expansion teeth is in screw feeder
Fixed on roller by rotatable guide pin bushing, flexible toothholder is servo-actuated with expansion teeth, reduce noise, and improve the use of expansion teeth
Life-span.
Brief description of the drawings
