Description
Technical field
The utility model relates to a kind of maize harvesting machine elevator.
Background technology
Chain drive is a kind of common power transmission mode, grain header is applied very extensive.Chain is in the normal process used, and chain can extend gradually, and sag can increase gradually, causes chain to produce violent beating, and even there will be and jumps tooth, de-tooth phenomenon, therefore should make its tensioning by adjusting chain in time.The elevator of such as maize harvesting machine, elevator is mainly delivered to fruit ear and section stem stalk in debarker device and is gone, in order to make elevator normally work, the rate of tension of elevator two chains should be consistent, and the tensioning adjustment of chain is realized by the adjusting screw(rod) at adjustment elevator driven axle two ends.And in practice due to the carelessness of maintaining and the loaded down with trivial details of frequent adjustment tensioning, be often difficult to remain that chain is in tensioning state.During use, once chain-loose, chain can wear and tear base plate, reduces operating efficiency, even part of damage.
Summary of the invention
The purpose of this utility model be to provide a kind of can the maize harvesting machine elevator of tensioning voluntarily after chain relaxes.
To achieve these goals, the utility model adopts following technical scheme: maize harvesting machine elevator, comprise housing, be located at the sprocket shaft that the fore-and-aft direction on housing extends, rotate the adapter sleeve be located on sprocket shaft, described housing is provided with the guide frame of the through hole had in left-right direction, described adapter sleeve is rotatably equipped with the adjusting rod that left and right directions extends, the left end of described adjusting rod and the corresponding side surface top press-fit of adapter sleeve, the right-hand member of described adjusting rod passes from the through hole of guide frame, described adjusting rod is arranged with spring in the left side of guide frame, the right-hand member of described spring and the press-fit of guide frame top, described adjusting rod is provided with the block left end of spring being carried out to axial limiting.
The left end of described adjusting rod is convexly equipped with the annular boss coordinated to the corresponding side block of adapter sleeve.
The connecting plate that described adapter sleeve comprises adapter sleeve body and is bolted to connection with adapter sleeve body, the left end of described adjusting rod and connecting plate rotate and assemble.
Described block is the hold-down nut that spiral is assemblied on adjusting rod.
Right side spiral in guide frame on described adjusting rod is equipped with locking nut.
The beneficial effects of the utility model are: the utility model is when installing and using, spring applies pretightning force by chain to it and carries out pre-compressed spring, when chain causes chain length to lengthen due to wearing and tearing or other reasons, spring release portion pretightning force promotes adjusting rod, adjusting rod pushing tow sprocket shaft makes the distance of the sprocket shaft of its use paired relative to another increase, and then tension chain, the utility model can realize the tensioning voluntarily of chain, ensures the normal operation of maize harvesting machine elevator.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Embodiment
The embodiment of the utility model maize harvesting machine elevator, as shown in Figure 1: comprise housing 1, be located at sprocket shaft 8 that fore-and-aft direction on housing 2 extends, rotate the adapter sleeve be located on sprocket shaft 8, sprocket shaft 8 is provided with sprocket wheel 10, sprocket wheel 10 is wound with chain 11.Housing 1 is provided with the guide frame 4 of the through hole had in left-right direction, guide frame 4 is cylindricality or square all passable, the connecting plate 7 that adapter sleeve comprises adapter sleeve body 9 and extends with the vertical direction that adapter sleeve body 9 is bolted to connection, adapter sleeve body 9 has the cylindrical section be rotatably assorted with sprocket shaft 8 and the support plate arranged in the upper and lower both sides of cylindrical section, support plate is provided with the bolt hole supplying the bolt of fixed connecting plate 7 to pass, connecting plate 7 is rotatably equipped with the adjusting rod 2 that left and right directions extends, the left end of adjusting rod 2 is convexly equipped with the annular boss coordinated with connecting plate 7 block of adapter sleeve, the space supplying the annular boss of adjusting rod 2 left end to rotate is formed between connecting plate 7 and support plate.The two ends of adjusting rod 2 are provided with external screw thread, the left end of adjusting rod 2 and the corresponding side surface top press-fit of adapter sleeve, the right-hand member of adjusting rod 2 passes from the through hole of guide frame 4, adjusting rod 2 is arranged with spring 5 in the left side of guide frame 4, right-hand member and the guide frame 4 of spring 5 push up press-fit, and on adjusting rod 2, spiral is provided with the hold-down nut 6 carrying out pushing up press-fit with the left end of spring 5.Right side spiral in guide frame 4 on adjusting rod 2 is equipped with locking nut 3.
By regulating the position of hold-down nut 6, the decrement of spring 5 can be changed.Adjusting rod 2 can be changed by adjusting lock nut 3 and be in length on the left of guide frame 4, and then the position of sprocket shaft 8 can be changed.
The utility model is when installing and using, spring 5 applies pretightning force by chain to it and carries out pre-compressed spring, when chain 11 causes chain length to lengthen due to wearing and tearing or other reasons, spring 5 release portion pretightning force promotes adjusting rod 2, the left end pushing tow of adjusting rod 2 sprocket shaft 8 makes its distance relative to another sprocket shaft increase, and then tension chain 11, the utility model can realize the tensioning voluntarily of chain, ensures the normal operation of machine.
In other embodiments, be provided with one end of annular boss and the assembling of adapter sleeve in order to what realize adjusting rod, also can be provided with the opening loaded for adjusting rod in the side of connecting plate.
In other embodiments, one end of the close adapter sleeve of adjusting rod also can not arrange annular boss.
In the present embodiment, the block left end of spring being carried out to axial limiting is the hold-down nut that spiral is assemblied on adjusting rod, being in order to the position by regulating hold-down nut, can changing the decrement of spring; In other embodiments, block can adopt nut, and nut is fixed on adjusting rod by the mode of welding, and block may also be the boss that adjusting rod is processed.
