Abstract
The utility model discloses a support structure of a header conveying chain. The support structure of the header conveying chain comprises a tensioning rack, the tensioning rack is provided with a rotating shaft which is connected rotationally, a bracket is arranged at the upper part of the rotating shaft, a tension sprocket is mounted at each of two sides of the bracket, the rotating shaft is welded and fixed with each of the upper end and the lower end of the bracket, and the upper head face of the rotating shaft and the upper head face of the bracket are located in the same horizontal surface. The support structure of the header conveying chain is good in connecting intensity and avoids the inconvenience due to the fact that the upper end of the rotating shaft protrudes out of the bracket.
Description
Technical field
the utility model relates to a kind of agricultural machinery technological field, relates in particular to a kind of grain header.
Background technology
corn picker mainly includes the ceding of Taiwan, elevator and tanker etc., and the described ceding of Taiwan comprises ear-picking unit and for standing position from front to back, carries the clamping convey device of cornstalk.Existing clamping convey device is to clamp cornstalk and complete conveying under the effect of cooperatively interacting of chain.
the supporting structure of existing corn harvester header chain front end comprises that tensioning frame 1, tensioning frame 1 are provided with the turning cylinder 2 being rotationally connected, turning cylinder 2 tops are provided with bracket 3, bracket 3 is provided with the tightener sprocket 4 for tension chain in turning cylinder 2 both sides, as shown in Figures 1 to 4.Existing turning cylinder 2 is by the axle sleeve 5 with in tensioning frame 3, to coordinate to realize to rotate, and turning cylinder 2 upper ends are stretched out bracket 3 upper surfaces and are welded and fixed with the upper end of bracket 3, because turning cylinder 2 and bracket 3 only weld in bracket 3 upper ends, therefore its integrated connection intensity is not fine, long-term use, between turning cylinder 2 and bracket 3, may become flexible, thereby affect the use of whole grain header.In addition, bracket 3 upper surfaces are stretched out in the upper end of turning cylinder 2, and the upper end of turning cylinder 2 protrudes from bracket 3, and because ceding of Taiwan overall structure is comparatively complicated, parts are also more, in use procedure, and the outstanding normal use that probably affects miscellaneous part of turning cylinder 2.
Summary of the invention
the utility model object is: the supporting structure that a kind of ceding of Taiwan chain is provided, it moves down turning cylinder integral body, and make the upper end of turning cylinder and bracket and lower end be welded and fixed respectively, so not only integrated connection intensity is better, and avoided turning cylinder upper end to protrude from bracket and the inconvenience that causes.
the technical solution of the utility model is: a kind of supporting structure of ceding of Taiwan chain, comprise that tensioning frame, tensioning frame are provided with the turning cylinder being rotationally connected, turning cylinder top is provided with bracket, bracket both sides are provided with tightener sprocket, upper end and the lower end of described turning cylinder and bracket are welded and fixed respectively, and the upper surface of turning cylinder and the upper end surface of bracket are in same level.
further, for the ease of upper end and the lower end of turning cylinder and bracket, be welded and fixed respectively, described turning cylinder is the Step Shaft that upper diameter is large, lower diameter is little, and the upper end of the axle sleeve in its step and tensioning frame is inconsistent and be rotatably assorted.In order to ensure contact area and the raising integrated connection intensity of axle sleeve and turning cylinder, described axle sleeve lower end is stretched out tensioning frame and is fixed with the stiffener of tensioning frame below.
the utility model has the advantages that:
1. the utility model moves down turning cylinder integral body, make upper surface and the bracket upper surface of turning cylinder remain on same plane, and make the upper end of turning cylinder and bracket and lower end be welded and fixed respectively, so not only integrated connection intensity is better, and has avoided turning cylinder upper end to protrude from bracket and the inconvenience that causes.
. the utility model is designed to Step Shaft by turning cylinder, when guaranteeing that itself and axle sleeve are rotationally connected, has facilitated the upper end of turning cylinder and bracket and lower end to be welded and fixed respectively.
. because turning cylinder of the present utility model is Step Shaft, making axle sleeve compare also integral body with original installation site moves down, the intensity that coordinates in order to ensure axle sleeve with tensioning frame, axle sleeve lower end is stretched out tensioning frame and is fixed with the stiffener of tensioning frame below, so just increased the contact area of turning cylinder and axle sleeve, connected more firm.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further described:
fig. 1 is the partial top view of the existing ceding of Taiwan;
fig. 2 is the schematic diagram of the supporting structure of ceding of Taiwan chain in prior art;
fig. 3 is the vertical view of tensioning frame in prior art;
fig. 4 is the end view of tensioning frame in prior art;
fig. 5 is structural representation of the present utility model;
fig. 6 is the vertical view of tensioning frame in the utility model;
fig. 7 is the end view of tensioning frame in the utility model.
wherein: 1 tensioning frame; 2 turning cylinders; 3 brackets; 4 tightener sprockets; 5 axle sleeves; 6 stiffeners.
Embodiment
embodiment: as shown in Figures 5 to 7, a kind of supporting structure of ceding of Taiwan chain, comprise that tensioning frame 1, tensioning frame 1 are provided with the turning cylinder 2 being rotationally connected, turning cylinder 2 tops are provided with bracket 3, bracket 3 both sides are provided with tightener sprocket 4, described turning cylinder 2 is welded and fixed respectively with upper end and the lower end of bracket 3, and the upper end surface of the upper surface of turning cylinder 2 and bracket 3 is in same level, so not only integrated connection intensity is better, and has avoided turning cylinder 2 upper ends to protrude from bracket 3 and the inconvenience that causes.
for the ease of turning cylinder 2 and upper end and the lower end of bracket 3, be welded and fixed respectively, described turning cylinder 2 is the Step Shaft that upper diameter is large, lower diameter is little, and the upper end of the axle sleeve 5 in its step and tensioning frame 1 is inconsistent and be rotatably assorted.
because turning cylinder 2 of the present utility model is Step Shaft, making axle sleeve 5 compare also integral body with original installation site moves down, the intensity that coordinates in order to ensure axle sleeve 5 with tensioning frame 1, axle sleeve 5 lower ends are stretched out tensioning frame 1 and are fixed with the stiffener 6 of tensioning frame 1 below, so just increased the contact area of turning cylinder 2 with axle sleeve 5, connected more firm.
below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the utility model scope required for protection.
