Description
Technical field
The present invention relates to a kind of united reaper parts, the lower cutter structure of especially a kind of united reaper.
Background technology
At present, owing to united reaper needs to utilize the ceding of Taiwan to shear stalk when carrying out grain harvesting, and delivery chute is passed through
The stalk sheared is delivered to thresing machine, but when the stalk of ceding of Taiwan shearing is long, brings relatively to delivery chute and thresing machine
Big operating load, and also longer from the stalk length of thresing machine discharge, cause stalk to become uneven distribution after shedding, and
Pathogenic bacteria are easily grown when distribution in arable land is excessively concentrated.Further, since stalk is wound around, delivery chute also can be caused to block,
Even produce fire by friction accident.When the stalk of ceding of Taiwan shearing is too short, longer stalk will be had to stay on arable land, also carry to cultivating
Carry out trouble.
Content of the invention
The technical problem to be solved in the present invention is: existing harvester, when cutting stalk, if retaining longer stalk, then cultivates fiber crops
Tired, if retaining shorter stalk, then harvester load is relatively big and blocking easily occurs.
