Description
Technical field
The invention belongs to agricultural machinery, and the cereal related generally on cereal Thresher used before stalk cutting plucks release mechanism.
Background technology
The research of threshing prior to cutting harvesting technology technical method just has begun in twentieth century, while threshing prior to cutting is at home
Outer is all a kind of new harvest technology.Stripping harvesting refer to threshing element do not cut in field using cereal before standing state it is direct
Grain is plucked from fringe head and taken off, then to pluck take off include the mixture such as grain, part cauline leaf, glume taken off again,
Separate and clean, so as to obtain the grain of cleaning.Because threshing prior to cutting takes early threshing, the harvest technology cut afterwards, therefore
There is simple in construction, efficiency high.But the defects of because of Thresher used before stalk cutting structure design, threshing cylinder is at a high speed during operation
Air current flow is driven in rotation process, negative pressure is produced around threshing cylinder, the negative pressure produces absorption affinity to cereal, therefore makes portion
Portion grain, which is attracted to, to be plucked on de- plate tooth, even if when grain is with plucking de- plate tooth and turning to the opening position that rear lateral portion should come off
Preferable solution can not be obtained so far the problems such as pluck the separation that come off on de- plate tooth, existing grain osses are big, bad adaptability.
The content of the invention
The purpose of the invention provides a kind of paddy of new construction aiming at the above-mentioned problems of the prior art, design
Thing threshing prior to cutting plucks release mechanism, reaches reliable, efficient, high quality is completed to the operation of cereal threshing prior to cutting, reduces grain osses
Purpose.
What the purpose of the invention was realized in：On roll circumference wall outer surface by fixed plate it is equipped pluck it is de-
Plate tooth, it is concentric on the side end of roller one to be fixedly mounted with driving pulley, it is concentric on gas transmission bucket axle outside portion and can turn
Dynamic mounting rotary drum, bar shaped blowhole is opened up in the roll circumference side wall, positioned at the position corresponding with plucking de- plate tooth,
Air vent is opened up on the gas transmission bucket axle circumferential side wall, is fixedly mounted with the gas transmission bucket axial wall portion outer surface by being oppositely disposed
Two pieces of fan-shaped end plates of two blocks of side plates and relative configuration enclose the bucket-shaped defeated air channel body even formed, and the bucket-shaped defeated air channel body is by gas transmission
Air vent on bucket axle is connected with the bar shaped blowhole on roller, and sealing is fixedly mounted with respectively on two pieces of side plate outer end outer side surfaces
Horn shape plate, the sealing horn shape plate contacts with inner wall of rotary drum face to be coordinated in sealing, on the defeated side end of wind bucket axle bucket bottom one
Angular adjustment assembly is fixedly mounted with, regulation handle is fitted on angular adjustment assembly, is so far formed cereal threshing prior to cutting and is plucked release mechanism.
The invention is come off grain separation from plucking de- plate tooth Co-coercivity using malleation air-flow stripping mode, significantly
Reduce the grain osses rate of threshing prior to cutting operation, have structure it is novel, rationally, grain rewind loss less, operation quality is good, makees
Industry efficiency high, use the characteristics of reliable, easy to adjust.

Embodiment
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of cereal threshing prior to cutting plucks off line
Structure, de- plate tooth 4 is plucked by the way that fixed plate 5 is equipped on the circumferential side wall outer surface of roller 6, it is coaxial on the side end of roller 6 one
The heart is fixedly mounted with driving pulley 2, concentric on the outside portion of gas transmission bucket axle 7 and rotatable mounting rotary drum 6, justifies in the roller 6
Bar shaped blowhole 3 is opened up in all side walls, positioned at the position corresponding with plucking de- plate tooth 4, in the circumferential side wall of gas transmission bucket axle 7
On open up air vent 11, two blocks of side plates 8 by being oppositely disposed and relative configuration are fixedly mounted with the wall portion outer surface of gas transmission bucket axle 7
Two pieces of fan-shaped end plates 10 enclose the bucket-shaped defeated air channel body even formed, the bucket-shaped defeated air channel body is by the air vent on gas transmission bucket axle 7
11 connect with the bar shaped blowhole 3 on roller 6, are fixedly mounted with sealing horn shape plate 9 respectively on two pieces of outer end outer side surfaces of side plate 8,
The sealing horn shape plate 9 contacts with the internal face of roller 6 to be coordinated in sealing, is fixedly mounted with defeated 7 barrels of bottoms one of wind bucket axle side end
Angular adjustment assembly 12, regulation handle 1 are fitted on angular adjustment assembly 12.
Before operation, the defeated angle position in roller 5 of wind bucket axle 7 is rotated by regulation handle 1 and angular adjustment assembly 12, made
Enclosed by two blocks of side plates 8 and two pieces of fan-shaped end plates 10 and connect the defeated air channel body formed and unload a direction towards roller 6；During operation, 6 turns of roller
Dynamic, de- plate tooth 4 of plucking thereon carries out threshing prior to cutting operation, and air-flow is successively through defeated wind bucket axle 7, air vent 11, defeated air channel body and bar
Shape blowhole 3, which blows to, plucks de- plate tooth 4, successively blows off and throws to rear the grain that is adsorbed on de- plate tooth 4 plucked for turning to discharge zone,
De- operation is plucked in completion.
