Description
Technical field
A kind of harvester component is the utility model is related to, more particularly to a kind of harvester chain automatic tension device.
Background technology
As Re-search on Urbanization transforms high speed development, rural laborer's critical shortage, gathers in problem getting worse, although agriculture
Popularized to a certain extent with machinery, the failure rate frequency of the frequent chain-taking of harvester of chain drive technology is high, and adjustment technology will
Ask the problems such as high anxious to be resolved.
The content of the invention
The purpose of this utility model is to provide a kind of harvester chain automatic tension device, this is with new expansion tightening wheel, axis
Hold, axis, stent by assemble formed one, spring be directly installed in the square tube of stent, outside spring and square tube, cover a square-tube-shaped
Into spring Self-pressurizing agri, automatic tension mechanism, the work efficiency for improving harvester is high.
The purpose of this utility model is achieved through the following technical solutions：
A kind of harvester chain automatic tension device, the tension device include expansion tightening wheel, tension shaft, tensioner stent, tensioner
Spring fairlead, tensioner spring；Bearing is equipped with expansion tightening wheel, bearing hole fork is equipped with axis pin, and the both ends of axis pin are connected to tensioner branch
On frame, the outer cover of tension shaft is equipped with guide sleeve, and tensioner spring is installed in the horizontal tensioner spring guiding perpendicular to axis pin
In set.
A kind of harvester chain automatic tension device, the outer contour of the expansion tightening wheel is in chain colyliform.
The advantages of the utility model is with effect：
This is directly installed in the square tube of stent with new expansion tightening wheel, bearing, axis, stent by assembling formation one, spring
Interior, outside spring and square tube, one square tube of set forms spring Self-pressurizing agri, automatic tension mechanism.The mechanism is adaptable, work
Efficient, stable equipment operation, security are good.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model crawler-type harvester chain automatic tension device.
Fig. 2 is the top view of Fig. 1.
Component in figure：Expansion tightening wheel 1, tension shaft 2, tensioner stent 3, tensioner spring fairlead 4, tensioner spring 5.
Embodiment
The utility model is described in detail in illustrated embodiment below in conjunction with the accompanying drawings.
A kind of harvester chain automatic tension device of the utility model, including expansion tightening wheel 1, tension shaft 2, tensioner stent 3, tensioner
Spring fairlead 4, tensioner spring 5 form.Bearing is equipped with expansion tightening wheel 1, bearing hole fork is equipped with axis pin, and the both ends of axis pin are connected to
On tensioner stent 3, the outer cover of tension shaft 2 is equipped with guide sleeve 5, and tensioner spring 5 is installed in rise perpendicular to the horizontal of axis pin
In tight spring fairlead 4.The outer contour of expansion tightening wheel 1 is in chain colyliform.
Expansion tightening wheel 1 is connected by bearing, set and tension shaft 2, is screwed to form one with tensioner stent 3 again, tensioner branch
The built-in upper tensioner spring 5 of frame 3, overcoat tensioner spring fairlead 4 form tension mechanism.Harvester expansion tightening wheel by tensioner stent,
Tensioner spring fairlead acts on the reaction force of spring, to realize the elastic of Self-pressurizing agri adjustment harvester chain.
