Description
Technical field
The present invention relates to the flexible feed mechanism of a kind of screw feeder, especially a kind of oscillating motion mechanism belongs to agricultural machinery technological field.
Background technology
Screw feeder is a kind of common spiral conveying mechanism, and the flexible feed mechanism of screw feeder is composited by spiral conveying mechanism outside the cylinder and the telescoping mechanism in the cylinder, is a kind of conveying mechanism of maturation.The structure of wherein initiatively taking off the finger telescoping mechanism can be 201010172171.4 Chinese patent document referring to application number.
When this mechanism being applied in the ceding of Taiwan of baby combine; When realizing the grain ear conveying of high stubble harvesting; There is following problem: refer to that the finger of initiatively taking off of all directions is contained on the eccentric shaft through referring to the pole socket spacer sleeve in the telescoping mechanism owing to initiatively take off; And refer to that pole socket is by all having certain axial dimension; Therefore adjacent in the same way spacing of initiatively taking off finger can't initiatively be taken off the direction number that refers to distribute (axial dimension that for example refers to pole socket is 80 millimeters, initiatively takes off to refer to divide four direction to distribute, then adjacent in the same way spacing of initiatively taking off finger can't less than 320 millimeters) less than referring to that pole socket axis size multiply by.As a result, refer to that spacing is bigger owing to initiatively take off, and the band grain ear stalk of high stubble harvesting is shorter, screw feeder is being pushed material in the carrier pipe process, and grain ear is easy to from slippage between referring to, pushes weak effect, has a strong impact on the harvesting effect of combine.
For head it off, the someone takes two flexible in the same way initiatively taking off are referred to expansion plate of welding between the outer end.Like this,, when low stubble gathers in,, very easily be stuck between expansion plate and the ceding of Taiwan headwall, form and stop up because the stalk of band grain ear is longer though solved grain ear to a certain extent easily from the problem of slippage between referring to.
Therefore, how to make the mass transport when ceding of Taiwan screw feeder on the baby combine is flexible to refer to that feed mechanism satisfies high and low stubble harvesting simultaneously require to become a difficult problem.
Summary of the invention
The objective of the invention is to: to an above-mentioned prior art difficult problem, a kind of ceding of Taiwan screw feeder feed mechanisms that stretch that refer to of mass transport can satisfy high and low stubble harvesting simultaneously the time are provided more.
In order to reach above purpose, ceding of Taiwan screw feeder of the present invention refers to that flexible feed mechanism comprises that by the shaft-driven cylinder body of power, said cylinder body outer surface is helical disk fixedly, is equipped with fixing eccentric shaft in the said cylinder body more; Be set with one group of finger pole socket spaced apart on the said eccentric shaft, extend on the said finger pole socket become with the ball pivot head that is placed in the cylinder body outer surface movingly initiatively take off finger; It is said that respectively initiatively taking off finger stretches out the cylinder body outer surface from three directions at least according to the order of sequence; Its improvements are: adjacent in the same way two in the said cylinder body initiatively taken off and is fixed with the connection crossbeam between the finger; Be fixed with the driven finger of taking off on the said connection crossbeam; Said driven taking off refers to take off the middle ball pivot head one-tenth that refers between the corresponding ball pivot head movingly with being placed in said adjacent in the same way active, and passes the cylinder body outer surface.
During running, the driven finger of taking off will be under the drive that connects crossbeam, takes off with the adjacent in the same way active of both sides to refer to expanding-contracting action.Because it is provided with the restriction that is not referred to the pole socket axial dimension, therefore can gather as required on the one hand, thereby when the harvesting of height stubble, avoid grain ear from slippage between referring to; On the other hand and since the cylinder body outer surface have only that all directions radially extend initiatively take off finger, and do not have any axial syndeton, therefore when low stubble harvesting, even the stalk of band grain ear is longer, can not can clamping stagnation form and stop up.
This shows that the present invention has solved the difficult problem of prior art with architecture advances cleverly, the needs of mass transport in the time of can satisfying high and low stubble harvesting simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the cutaway view of Fig. 1.
Embodiment
Embodiment one
The ceding of Taiwan screw feeder of present embodiment refers to that flexible feed mechanism is as shown in Figure 1 more, and cylinder body 7 is supported on the bearings at both ends, is driven by line shaft 8, and outer surface is helical disk 6 fixedly.The eccentric shaft 1 that is fixed on two end cranks 11 is equipped with in its inside.Be set with one group of finger pole socket 2 spaced apart on this eccentric shaft, refer on the pole socket to extend towards the outer surface of cylinder direction and assign handle, wherein fixing initiatively the taking off of plug-in mounting refers to 3, and each is initiatively climbed onto a slow-going train and refers to become movingly with ball pivot head 9 central hole that are placed in cylinder body 7 outer surfaces.Because ball pivot head 9 is arranged from the four direction of cylinder body 7 circumference uniform distributions according to the order of sequence, therefore each initiatively takes off finger 3 stretches out cylinder body 7 according to the order of sequence from four direction outer surface.In order to make the spacing of initiatively taking off finger in the same way can satisfy the needs of high stubble harvesting; Be fixed with between in the cylinder body 7 adjacent in the same way two initiatively taken off and referred to 3 and connect crossbeam 5; The centre that connects crossbeam 5 is fixed with driven taking off and refers to 4; Each is driven take off refer to 4 be placed in adjacent in the same way active take off between the finger 3 corresponding ball pivot heads 9 10 one-tenth on middle ball pivot head movingly, and pass cylinder body 7 outer surfaces.
When cylinder body driven shaft driven rotary, helical disk 6 will be realized the conveying of material.Simultaneously, all are initiatively taken off under the effect of finger with eccentric shaft, and back and forth flexible in the cylinder rotation process, wherein driven taking off by the connection horizontal sill bolt moved, and take off with the adjacent in the same way active of both sides to refer to the synchronization telescope action.Owing to initiatively take off the restriction that the finger spacing is no longer referred to the pole socket axial dimension, therefore gather as required, thereby when high stubble gathers in, avoid grain ear from slippage between referring to.Therefore this structure also can be applicable to low stubble harvesting because the cylinder body outer surface does not only have any axial syndeton, can not stop up because the stalk of band grain ear is long.
Except that the foregoing description, the present invention can also have other embodiments.For example, driven taking off refers to be threaded with being connected the crossbeam employing, like this can be very easily dismounting and adjusting length as required.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
