Existing flexible toothholder adopts cast iron to make, and exists the big and high shortcoming of manufacturing cost of processing capacity, and the back expansion teeth axle easy to wear that works long hours during combine harvesting operation, in case the expansion teeth axle damages, is changed very loaded down with trivial detailsly, influences and gathers in.
The utility model content
The purpose of this utility model provides a kind of combine harvester cutting table screw feeder expansion teeth device of easy to maintenance, long service life.
The utility model is achieved by the following technical programs:
A kind of combine harvester cutting table screw feeder expansion teeth device comprises screw feeder cylinder, expansion teeth supporting mechanism, and described expansion teeth supporting mechanism is arranged in the ceding of Taiwan screw feeder, comprises first back shaft, second back shaft, radius bar, expansion teeth axle, several expansion teeth groups; Fixedly connected with radius bar one end respectively in described expansion teeth axle two ends, the described radius bar other end is fixedlyed connected with first back shaft, one end, second back shaft, one end respectively, first back shaft, second back shaft respectively by several on the width of cloth dish of bearings in the screw feeder cylinder; Axially spaced-apart between several expansion teeth groups, be staggered, described expansion teeth group comprises in a row spaced several expansion teeths, flexible toothholder, and described flexible toothholder is hinged with the expansion teeth axle respectively; Described expansion teeth one end is fixedlyed connected with flexible toothholder, and the expansion teeth other end passes the circumference of screw feeder cylinder; Described flexible toothholder lower end is provided with the through hole that cooperates with expansion teeth between centers crack, and flexible toothholder upper end is provided with the screwed hole of fixedlying connected with expansion teeth one end.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid combine harvester cutting table screw feeder expansion teeth device, the material of wherein said flexible toothholder is a nylon, flexible toothholder upper end is provided with the nut of tape spool shoulder.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
Flexible toothholder of the present utility model adopts injection mo(u)lding, need not carry out machined, and production efficiency height and light weight have reduced manufacturing cost, again because of its material is a nylon, and not only wear-resisting, long service life, and the expansion teeth axle that can not wear and tear after working long hours.The utility model directly is injection molded into one with the nut and the flexible toothholder of tape spool shoulder, and expansion teeth one end directly screws with nut and is connected.Compare with cast iron quality, the connecting thread of expansion teeth one end of the present utility model and nut is not fragile, connects more reliably, and long-time use can not cause wear damage to the expansion teeth axle.Flexible toothholder nut of the present utility model has the shaft shoulder, can prevent to break away under action of centrifugal force when expansion teeth from rotating flexible toothholder.
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 a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the I portion enlarged drawing of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the utility model comprises screw feeder cylinder 1, expansion teeth supporting mechanism 2, weld several width of cloth dishes 11 in the screw feeder cylinder 1, both can be used for improving the intensity of screw feeder cylinder 1, can be used for supporting the expansion teeth supporting mechanism 2 that is arranged in the ceding of Taiwan screw feeder 1 again.Described expansion teeth supporting mechanism 2 comprises first back shaft 21, second back shaft 22, radius bar 23,24,4 expansion teeth groups 25 of expansion teeth axle.Fixedly connected by connecting pin with radius bar 23 1 ends respectively in expansion teeth axle 24 two ends, radius bar 23 other ends are fixedlyed connected with first back shaft 21, second back shaft, 22 1 ends respectively, first back shaft 21, second back shaft 22 are supported in the screw feeder cylinder 1 bearing 12 by several on the width of cloth dish 11 are set respectively, screw feeder cylinder 1 one ends can rotate around first back shaft 21, second back shaft, 22 centers, and screw feeder cylinder 1 other end (not drawing among Fig. 1) is fixedlyed connected with driving shaft.Expansion teeth axle 24 and first back shaft 21 that is positioned at screw feeder cylinder 1 center, between second back shaft 22 certain eccentric throw is arranged, axially spaced-apart between 4 expansion teeth groups 25, be staggered, expansion teeth group 25 comprises in a row spaced 2 expansion teeths 251 respectively, flexible toothholder 252, described flexible toothholder 252 lower ends are respectively by hinged with the through hole and the expansion teeth axle 24 of expansion teeth axle 24 matched in clearance, expansion teeth 251 1 ends are fixedlyed connected with flexible toothholder 252, the material of flexible toothholder 252 is a nylon, flexible toothholder 252 upper ends are provided with the nut 253 of tape spool shoulder, can prevent expansion teeth 251 when expansion teeth axle 24 rotates, nut 253 breaks away from flexible toothholder 252 under action of centrifugal force.Expansion teeth 251 1 ends are hinged with expansion teeth axle 24 by flexible toothholder 252, and the other end passes the circumference of screw feeder cylinder 1, and screw feeder cylinder 1 is every 90 ° of circumference that pass screw feeder cylinder 1 with regard to the other end that 2 expansion teeths 251 are arranged.
As shown in Figure 2, screw feeder cylinder 1 clockwise rotates as the direction of arrow indication, and expansion teeth axle 24 is horizontal, and remains unchanged with respect to the position of the ceding of Taiwan 3.Because expansion teeth axle 24 is positioned at the eccentric position of screw feeder cylinder 1 circumference, when screw feeder cylinder 1 rotated, the expansion teeth in a row 251 of interlaced arrangement realized that the rake material moves stretch respectively around screw feeder cylinder 3 centers when rotate at expansion teeth axle 24 centers.When expansion teeth 241 rotates to position near ceding of Taiwan base plate 31 along with screw feeder cylinder 1, expansion teeth 241 stretches out gradually, crops on the ceding of Taiwan base plate 31 can be pulled over to the feeding mouth 32 of ceding of Taiwan rear side, when expansion teeth 241 rotates to feeding mouth 32 positions near ceding of Taiwan rear side along with screw feeder cylinder 1, expansion teeth 241 is withdrawn gradually, prevents from crops are taken away.
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.
