Description
Technical field
The present invention relates to a kind of rear linkage, more particularly to a kind of rear linkage for being connected to chassis main frame
Background technology
Existing crawler type agricultural machinery, its rear linkage is directly installed on power output transmission case, makes transmission case
Very big external force is received, having a strong impact on the intensity of casing causes it to damage, lifting arm lengths are short, cause the liter with its agricultural equipment
Drop stroke is limited, and leverages the service behaviour of rotary cultivator, the rear overhang hanger narrower width on transmission case,
Influence the left and right stability of agricultural equipment.
Crawler belt walks rotary tillage stubble-cutting machine certainly for example disclosed in Publication No. CN202713898U, the swivel point of its hanger bracket two-arm
Design is on power output transmission case case lid, after agricultural equipment has been hung, and can be produced centered on the tie point of hanger bracket
One upward turning moment is acted on case lid, makes case lid by larger external force, suffered on transmission case case lid to reduce
External force, so lifting arm lengths can not design oversize, causes the lifting travel of supporting agriculture to be limited, transmission case width itself
It is smaller, influenceed by casing width, rear overhang hanger width will be limited, i.e., can influence the left and right stability of agricultural equipment.
Also, in the prior art, because rear linkage is connected with main body non-dismountable, when rear linkage occurs
When deformation or damage, maintenance difficulty is very big, often results in whole main frame and is in service mode for a long time；The portion of back suspension device
