The utility model is to realize like this, a kind of sealing device of grain discharge drum of combine, comprise and be arranged on described grain barrel-removing grain outlet place and the sealing plate for grain outlet described in switch, described sealing plate is connected with described grain barrel-removing by elasticity reset device, described elasticity reset device comprises the connecting axle being rotatably installed on described grain barrel-removing, described sealing plate is connected with described connecting axle by coupling assembling, and described connecting axle is provided with the back-moving spring that makes described sealing plate recover initial position.
As improving further, one end of described connecting axle is rotatably installed on the first connecting plate, the other end is rotatably installed on the second connecting plate, described the first connecting plate and the second connecting plate are oppositely arranged on described grain barrel-removing, described back-moving spring is U-shaped torsion spring, one end of described U-shaped torsion spring is connected with described the first connecting plate, and the other end is connected with described the second connecting plate, the U-shaped arm in centre of described U-shaped torsion spring and described sealing plate overlap joint.
As improving further, coupling assembling comprises the first cursor and the second cursor, described the first cursor and the second cursor relative being set on described connecting axle respectively, described the first cursor is near described the first connecting plate, described the second cursor is near described the second connecting plate, described the first cursor and the second cursor be fixedly connected with corresponding with described sealing plate respectively, the torsion spring of described U-shaped torsion spring one side is between described the first connecting plate and the first cursor, the torsion spring of a relative side is between described the second connecting plate and the second cursor, and the first cursor and the second cursor are positioned at the U-shaped arm in described centre.
As improving further, described the first connecting plate is connected with the outer wall of described grain barrel-removing with the second connecting plate.
Adopted after technique scheme, the beneficial effects of the utility model are:
Because sealing plate is connected with described grain barrel-removing by elasticity reset device, described elasticity reset device comprises the connecting axle being rotatably installed on described grain barrel-removing, described sealing plate is connected with described connecting axle by coupling assembling, described connecting axle is provided with the back-moving spring that makes described sealing plate recover initial position, when unloading, the grain outlet that unloading screw conveyor promotion grain is opened grain barrel-removing carries out unloading, after unloading finishes, under the effect of back-moving spring, make sealing plate recover initial position, close grain outlet, the grain barrel-removing end that has solved existing use does not have sealing plate, meeting residual a part of grain in gap between unloading screw conveyor and grain barrel-removing after unloading finishes, in follow-up harvesting process, grain barrel-removing vibrates along with harvester operation, the problem that residual grain spills from grain barrel-removing grain outlet, good sealing effect, avoid foodstuff waste, convenient operation.
