Abstract
The utility model provides a grass guide mechanism for threshing room of combine, which is characterized in that the traditional semi-circular cylinder-shaped convex cover cap is changed into a cuboid-shaped convex cover cap. The inner wall of the long edge cover plate of the convex cover cap is provided with a plurality of longitudinal hinges which are in parallel arrangement. The bottom edge of the thin plate form threshing segment grass guide plate is closely matched with the inner wall surface of the convex cover cap along the longitudinal direction. The bottom edge of one end of the thin plate form threshing segment grass guide plate is connected with a hinge, and the center section of the bottom edge is vertically fixed to a screw rod. The front end of the screw rod is threaded out of the long cambered sliding rod slotted hole arranged on the top plate of the convex cover cap, and fixed to the long cambered sliding rod slotted hole via a cap nut. The utility model can flexibly adjust the intersection angle of the threshing segment grass guide plate and the threshing drum shaft line, namely, the running speed of the straw in the threshing room can be adjusted, which can make the combine flexibly fit to the harvesting and threshing requirement of various kinds of cereals of different varieties or the cereals of the same variety but different maturities.
Description
Technical field
The utility model relates to the threshing chamber member of grain combine.
Background technology
Existing grain combine threshing chamber lead careless mechanism, form by concave grate that is installed on threshing cylinder in the threshing chamber, threshing cylinder below and threshing chamber top cover that the grass guide board bar is installed.The grass guide board bar is to be installed on the grand cover cap internal face of the semi-cylindrical shaped that swells at threshing chamber top cover middle part, and wherein several threshing section grass guide board bars and threshing cylinder axially form an angle.During threshing chamber work, its surperficial spike-tooth of the threshing cylinder of high speed rotating constantly impacts the straw that is fed, and drives the annular space space that forms between cylinder inner wall that straw constitutes along the grand cover cap of the semicircular cylinder of concave grate and threshing chamber top cover and the threshing roll cylindrical shell simultaneously and does the spiral forward travel.During this, grain is constantly split away off from straw, passes concave grate and falls into collection grain screw feeder.When straw turned round straw outlet to threshing chamber, the grain on the straw had come off totally, and straw is discharged from outside the machine.And straw the speed of travel that the threshing chamber inside spin advances be depend on grass guide board bar quantity on the grand cover cap inwall of threshing chamber top cover semicircular cylinder what and with the size of drum shaft to angle of cut α, grass guide board bar quantity is many, little with drum shaft to angle of cut α, then the straw speed of travel is slow, through threshing, but power consumption is big, also easily causes the fragmentation of grain.Otherwise straw speed of travel in threshing chamber is fast, and power consumption is few, but threshing is difficult clean, can cause waste to increase.Yet the threshing section grass guide board bar structure on the traditional threshing chamber cover device of grain header is all fixed, thereby it only is fit to the harvesting threshing needs of certain crop varieties.And the threshing of the various kind cereal of flexible adaptation or same kind differing maturity cereal needs best.
Summary of the invention
The technical problem that the utility model quasi-solution is determined, be to make grain combine can regulate the speed of travel of straw neatly, can both efficiently gather in threshing in high quality to different cultivars cereal or differing maturity cereal extensively to adapt to neatly at threshing chamber.
The technical scheme that addresses the above problem is: it comprises the threshing cylinder that is installed in the threshing chamber, the concave grate of threshing cylinder below and the grand cover cap of the threshing chamber top cover that several threshing section grass guide board bars are installed, it is characterized in that the grand cover cap of threshing chamber top cover is the cuboid cover cap that matches with the concave grate upper oral part, one long limit cover plate inwall of grand cover cap is equipped with the hinge that several vertically parallel arrangement, its base of plate-shaped threshing section grass guide board bar is and swells vertically proper mutually three foldable edges that cooperate of cover cap internal face, the limit, upper end is and the corresponding arcs of recesses of concave grate limit, the limit, one bottom of this grass guide board bar is connected with hinge, base, stage casing vertical fixing has a screw rod, offer the long arc shape slide bar slotted eye that matches with screw rod on the top board of grand cover cap, screw front end passes the slide bar slotted eye on the top board, is connected to a fixed with nut.
Outstanding advantage of the present utility model is: an end of its threshing section grass guide board bar is connected with hinge, the other end can free slippage, fixing, thereby regulated the angle of cut α of grass guide board bar and threshing cylinder axis neatly, also promptly regulated the speed of travel of straw in threshing chamber, made the harvesting function threshing needs of the various different cultivars cereal of flexible adaptation or same kind differing maturity cereal best.

Embodiment
The utility model is the grand cover cap 9 of cuboid with the grand cover cap transformation of the way of the semicircular cylinder of traditional threshing chamber top cover 4, and still match with concave grate 2 upper oral parts, long limit cover plate inwall at grand cover cap 9 is installed 3-5 hinge 8 that vertically parallels arrangement, plate-shaped threshing section grass guide board bar 6, its base is and swells vertically proper mutually three foldable edges that cooperate of cover cap 9 internal faces, the limit, upper end is and concave grate 2 corresponding arcs of recesses limits, the limit, one bottom of this grass guide board bar 6 is connected with hinge 8, base, stage casing or base are prolonged to the level of a side and are fixed with a screw rod 14 on the limit 13, offer the long arc shape slide bar slotted eye 7 that matches with screw rod 14 on the top board 10 of grand cover cap 9, after screw rod 14 front ends pass slide bar slotted eye 7, be connected to a fixed with the hand-screw nut 15 of handled easily.Also be installed with a feeding section grass guide board bar 5 at grand cover cap 9 inwalls in addition.The structure that the utility model is provided with the threshing chamber 1 of feeding mouth 12, straw outlet 11 and threshing cylinder 3 and concave grate 2 is identical with traditional structure.
