Crawler belt is after walking one segment distance, certain relaxing can be there is in track takeup, need the tensioning degree adjusting crawler belt, the tensioning degree of crawler belt is adjusted by tightening device, and tightening device realizes the parts mainly push rod to crawler tensioning function, at present, existing tracks of harvester tensioning push rod is mostly Integer push rod structure, because the installing/dismounting of Integer push rod structure is all more difficult, installing/dismounting process time is long, and work efficiency is low.
Utility model content
In order to solve above-mentioned Problems existing, the utility model discloses a kind of pusher structure of tracks of harvester tightening device, its concrete technical scheme is as follows:
A kind of pusher structure of tracks of harvester tightening device, for regulating tightening device to the tensile force of crawler belt, this tightening device comprises two tension wheels, two tension wheels bear against crawler belt from crawler belt inner support respectively, crawler belt is strutted by two tension wheel tensionings, the center shaft of described each tension wheel is provided with tension wheel bearing and pusher body, described each tension wheel bearing and pusher body all extend towards another tension wheel direction, one end of described pusher body is inserted in tension wheel bearing, the other end is inserted in guide thimble, described guide thimble is supported between two tension wheels, described tension wheel bearing settlement has for limiting pusher body moves axially or circumference rocks caging bolt and the demounting bolt for dismantling pusher body.
The circumferential surface of described pusher body is provided with position-limited trough, and described caging bolt bear against in the position-limited trough of pusher body through the sidewall of tension wheel bearing, and described caging bolt and pusher body radial direction are arranged.
Described demounting bolt bear against pusher body through the end of tension wheel bearing, and described demounting bolt and pusher body are axially arranged.
Described tension wheel bearing settlement has the push-rod hole of axial depression, and described push-rod hole is towards another tension wheel direction in same crawler belt, and one end grafting of described pusher body is fixed in push-rod hole.
Described tension wheel bearing is connected with the center shaft of tension wheel by connecting panel.
Then pusher body is overlapped in one end of described guide thimble, and the other end connects tensioning regulating mechanism.
Principle of work of the present utility model is:
After combination machine walking LAP, certain absent-mindedness can be there is in crawler belt, crawler belt after absent-mindedness is unfavorable for normally controlling walking, needs by crawler tensioning to suitable tensioning degree, the utility model, by adjustment tensioning regulating mechanism, to the pressure of guide thimble towards tension wheel, guide thimble moves towards tension wheel, and then drives pusher body to move towards tension wheel, and then drive tension wheel to move towards the position compressing crawler belt, crawler belt is tightened.
The utility model, at pusher structure et out of order, when needing dismounting and maintenance pusher structure, caging bolt turned on by spiral, demounting bolt is screwed in tension wheel bearing, fast pusher body can be dismantled, because pusher body two ends are inserted in tension wheel bearing and guide thimble respectively, after one end takes apart from tension wheel bearing, just can like a cork pusher body be dismantled away, integral type push rod that pusher body is more traditional, dismantle more flexible, install and keep in repair easier, simultaneously, maintenance cost reduces, whole push rod is needed to change after traditional push rod fault, waste of material is serious, waste money.
The beneficial effects of the utility model:
1. the utility model pusher body two ends are socketed in guide thimble and tension wheel bearing respectively, and the Integral pushrod length that the length of pusher body is more traditional diminishes, and Assembly &Disassembly is more flexible;
2. the utility model is provided with demounting bolt, during dismounting pusher body, is pushed out by pusher body, dismantle easier by demounting bolt from tension wheel bearing;
3. the utility model is provided with caging bolt, more easily can control the position of pusher body in tension wheel bearing, easier for installation and be easy to control;
4. pusher body of the present utility model is installed, is dismantled simple, shortens the time, improves maintenance efficiency, change pusher body cost low, be convenient to wide popularization and application.
