Description
Technical field
The present invention relates to the agricultural product harvest equipment technical fields in agricultural machinery, and in particular to a kind of double helix is double flexible
Reversal means feeds screw feeder.
Background technique
The ceding of Taiwan is one of main working parts of combined harvester, and feeding screw feeder is the device for transporting objects in the ceding of Taiwan, into
The stalk for entering the ceding of Taiwan is delivered to intermediate conveying device by spiral-poker.
Existing only one most feeding mouth of routine harvester header, feeding screw feeder convey material towards a feeding mouth.
When swath is larger, unilateral screw feeder conveying distance is remote, and power consumption is big, is easy blocking.Chinese patent 201620545622.7, it is entitled
" a kind of two cutting tables twin-roll high-clearance rice harvesting machinery " discloses a kind of suitable ratooning rice and common rice harvest and efficiently low
The harvest machinery rolled, it is disclosed that a kind of double receipts fringe cedings of Taiwan, i.e. two sets of independent cedings of Taiwan are stitched together, each Self Matching one
Other workpieces such as threshing cylinder are covered, shunt the spike of rice of harvesting in the middle part of two cedings of Taiwan by a nearside divider.But disclosed in the patent
There are gaps in the middle part of two sets of cedings of Taiwan, and dividing standing grain effect to be not thorough causes spike of rice leakage to be cut.Furthermore two sets of individual screw feeders need two sets of biographies
Dynamic system, structure is complicated and quality weight.
What single flexible reversal means structure of feeding mouth cutting table auger common at present generallyd use is a kind of Simple crank slide block mechanism,
Crank is motionless, and reversal means had not only rotated but also done movement.When it is two that ceding of Taiwan feeding mouth, which increases, can this traditional structure meet need
It asks, not yet finds such related content in domestic and foreign literature patent at present, therefore it is necessary to propose corresponding construction and its arrangement
Mode.
Summary of the invention
By two sets of flexible reversal meanss, independently separated double flexible reversal meanss feedings of double helix are stirred the object of the present invention is to provide a kind of
Dragon shortens material conveying distance, slows down the case where stalk accumulation causes the ceding of Taiwan to block, enhances adaptation of the screw feeder to feed quantity
Property, power consumption is reduced, the operating efficiency of combine harvester is increased.
To further realize above-mentioned purpose, the invention adopts the following technical scheme: a kind of double flexible reversal means feedings of double helix
Screw feeder, it is short including screw feeder cylinder, the left-handed short blade being centered around on the outside of screw feeder cylinder, dextrorotation linear leaf, left-handed linear leaf, dextrorotation
Blade, the flexible reversal means mechanism in the left side for being arranged in screw feeder inner barrel, right flexible reversal means mechanism, the left-handed short blade, dextrorotation are long
