Specific embodiment
As shown in Figs. 1-3
A kind of sheller unit of combine harvester, the sieve plate 2 including thrashing cylinder 1 and with the cooperation of thrashing cylinder 1, thrashing cylinder 1 include
Barrel 11, the multiple rows of threshing column 12 being uniformly arranged along 11 whole body of barrel, connect the first spring 13 of adjacent threshing column 12, and first
Spring 13 is extension spring；Threshing column 12 includes the quiet column 121 for being fixedly installed on barrel 11, axial to be hingedly set to barrel 11
Dynamic column 122, a dynamic column 122 and a quiet column 121 form a threshing column 12, and dynamic column 122 is not integrated with quiet column 121,
Dynamic column 122 is located at the upstream of 1 rotation direction of thrashing cylinder, and quiet column 121 is located at the downstream of 1 rotation direction of thrashing cylinder；Moving column 122 includes
The first pars intramuralis 1,222 1221 outside first wall in 11 outside of barrel, positioned at 11 inside of barrel, quiet column 121 include being located at
1211, the second pars intramuralis 1212 positioned at 11 inside of barrel outside second wall in 11 outside of barrel；1221 protrusion outside first wall
Height be greater than the second wall outside 1211；First pars intramuralis 1222 is separated by with the second pars intramuralis 1212, and be located at rotation direction
The second adjacent pars intramuralis 1212 of upstream is connected by the first spring 13, under the pulling force of the first spring 13, makes column 122 not
By material extruding when keep static；Second pars intramuralis 1212 is provided with for feeding back the first pars intramuralis 1222 to the second pars intramuralis
1212 squeeze the feedback mechanism 14 of situation.When work, thrashing cylinder 1 is rotated, and material, which enters between thrashing cylinder 1 and sieve plate 2, to be extruded
Rubbing carries out threshing.1221 setting different from 1211 length outside the second wall, realizes staged to material outside first wall
Extruding and kneading, Threshing is more preferable.First wall outside 1221 and the first pars intramuralis 1222 are respectively by material and the first spring
13 toward updrift side active force, dynamic column 122 trembles, and the extruding and kneading space of material changes therewith, and realization is to material
Elastic extruding and kneading, and reduce the risk of feed blocking.First spring 13 is corresponding according to 1 driving device driving force of thrashing cylinder
The high extension spring of the stiffness factor of configuration, in normal operation, material is insufficient to outside the first wall 1221 active force
Squeezing outside the first wall 1221 to extreme position, the slightly trembling in a certain range of column 122 is moved.When material more congestion
When, the first wall outside 1221 will receive bigger extruding and rotate toward updrift side, outside the first wall between 1221 and sieve plate 2 most
Short distance is widened, and the extruding and kneading space of material is released, and avoids the generation of feed blocking.When material congestion level very
When serious, material squeezes 1221 pulling force for also making the first pars intramuralis 1222 overcome the first spring 13 to extreme position outside the first wall
The second pars intramuralis 1212 toward downstream position is close to triggering feedback mechanism 14, by the travel switch being set in feedback mechanism 14
144 issue alarm signal.
Further, feedback mechanism 14 includes filling the hydraulic fluid tank 141 of grease, and one end is set in hydraulic fluid tank 141 and another
One end protrudes from 1212 surface of the second pars intramuralis and the first stick harness 142 towards upstream, and one end is set in hydraulic fluid tank 141 and another
One end is located at the second stick harness 143 outside hydraulic fluid tank 141, is set to the travel switch 144 on 143 opposite of the second stick harness.First plug
Column 142 and the second stick harness 143 include to limit its elastic component stable with 141 relative position of hydraulic fluid tank, such as spring, and first
Sealed between stick harness 142 and the second stick harness 143 and hydraulic fluid tank 141 by sealing ring, the first stick harness 142 and the second stick harness 143 by
It can be subjected to displacement in hydraulic fluid tank 141 when power；Grease in hydraulic fluid tank 141 is paste, such as the industrial butter of lithium saponify.First plug
Column 142 is squeezed by the first pars intramuralis 1222 and is moved in hydraulic fluid tank 141, and the second stick harness 143 is toward mobile outside hydraulic fluid tank 141, when the
Two stick harnesses 143 are moved to when withstanding travel switch 144, and travel switch 144 issues alarm signal.
Further, the second stick harness 143 include insert to hydraulic fluid tank 141 suspension column 1431 and be set to the top of suspension column 1431
Column lid 1432, axis of the column lid 1432 towards thrashing cylinder 1；Second hydraulic fluid tank 141 is provided with the convex block 1411 for being convex to column lid 1432；
Convex block 1411 is provided with the groove 145 matched with column lid 1432；First spring 13 is located at one end packet of the second pars intramuralis 1212
The wirerope 131 passed through from groove 145 is included, wirerope 131 includes bulge 1311.The state that second stick harness 143 is not ejected,
Column lid 1432 is touched with 1411 phase of convex block, and groove 145 forms the line hole passed through together for wirerope 131.Wirerope 131
One end is connect with the ontology of the first spring 13, and the other end passes through line hole, and the line footpath of bulge 1311 is greater than the hole diameter in line hole, passes through
Line hole and bulge 1311 prevent the downstream down of wirerope 131, realize the fixation to the first spring 13.When the second stick harness
143 when being ejected, and with the separation of convex block 1411 and column lid 1432, line hole disappears to the position-limiting action of bulge 1311, the
Under the pulling force of one spring 13, wirerope 131 is downstream pulled, the second pars intramuralis of first pars intramuralis 1222 in downstream close to downstream
1212, while the column lid 1432 being ejected is moved to and withstands travel switch 144, travel switch 144 issues alarm signal.
Further, feedback mechanism 14 further includes rotatable for winding the collection line wheel 146 of wirerope 131.Wirerope
131 length wound can trigger downstream close to second pars intramuralis 1212 in downstream with the first pars intramuralis 1222 for meeting downstream
Feedback mechanism 14 needed for subject to stroke.
Further, column 122 is moved perpendicular to barrel 11.When dynamic column 122 is not squeezed by material, in the tension of the first spring 13
Dynamic column 122 is perpendicular to barrel 11 down.
Further, the first wall outside 1221 in the same threshing column 12 is in contact with outside the second wall 1211.
Further, the first wall outside 1221 in the same threshing column 12 is provided with outside the second wall 1211 matches
Plug portion 123.1221 setting lug bosses or recessed portion i.e. outside the first wall, 1211 settings match outside the second wall
Depressions or protrusions portion, in working condition, plug portion 123 plugs with outside the first wall 1221 trembling back and forth, prevents
Material fine crushing enters between 1211 outside the first wall outside 1221 and the second wall.
Further, thrashing cylinder 1 further include coaxially be fixedly installed on inner barrel for extraneous gas to be inputted threshing
Air inlet pipe 15 inside cylinder 1, air inlet pipe 15 are provided with towards the gas outlet of sieve plate 2 151；Dynamic column 122 in same threshing column 12
Barrel 11 between quiet column 121 is provided with blow vent 111.Thrashing cylinder 1 drives rotation, air inlet by the driving device on harvester
Pipe 15 does not rotate with thrashing cylinder 1, and gas blows to the threshing column 12 in 2 region of sieve plate by gas outlet 151, and passes through blow vent
111 blowouts.At work, the first wall outside 1221 and the second wall outside 1211 separate when generating gap, and gas is blown out from gap
Material is acted on, threshing is promoted and prevents fine crushing material from entering between 1211 outside the first wall outside 1221 and the second wall.
Further, gas outlet 151 is spaced setting along barrel 11 all over the body.In order to make gas generate strong and weak switch type to material
Active force, increase anti-blocking ability, inventor is by the setting of gas outlet 151 to close to the first pars intramuralis 1222 and the second pars intramuralis
1212, and gas outlet 151 is spaced setting along barrel 11 all over the body.
