Description

Double freedom becomes type hole discharge plate

Technical field

The invention belongs to agricultural machinery, relates generally to a kind of type hole and becomes in the variable double freedom of both direction size Type hole discharge plate.

Background technology

At present, the Pneumatic type in feed mechanism for seed is because using having special seeding principle to the dimension precision requirement of seed not Height, big small-sized seed can all be sowed, with varietal adaptation it is strong the characteristics of, and be adapted to high-speed job, but its price, and making Blower fan need to be equipped with during industry to use；And mechanical seed sowing device, with respect to Pneumatic seeding apparatus, with simple structure, cheap is excellent Point, but because it uses the type hole by seed deadweight passively to fill kind of a principle naturally, and the parameters of structural dimension of type hole is constant, is intended to realize Precision drilling, need to carry out sizing screening to seed, it is ensured that seed appearance and size is tried one's best uniformity, generally, unscreened kind Son, it may appear that replay rate and the phenomenon of leakage sowing rate increase, influences seeding operation quality.For same crop, such as soybean, its hundred Size difference is very big between weight scope 10g~30g, same crop different cultivars, and for Different Crop such as corn, soya bean, peanut Deng between crop, not only size is had differences, and contour structures are also differed, therefore, how to be changed by Creative Mechanism Design The size of mechanical discharge plate type hole parameters of structural dimension, to adapt to the different type of Different Crop or same crop, as machine The key of tool formula discharge plate type hole design.

The content of the invention

A kind of problem that the purpose of the invention exists aiming at above-mentioned prior art, double freedom of research and design becomes Type hole discharge plate, by rotating adjusting nut, changes from radial direction and axial both direction and type hole is constructed on the discharge plate face of cylinder Physical dimension, realizes that the stepless change of operation type hole size is adjustable, solves mechanical discharge plate type hole to Different Crop and same The technical problem of the adaptability of one crop different cultivars.

What the purpose of the invention was realized in：Pass through chute and raised line in the U-lag that discharge plate circumference is opened up Between sliding block coordinate and radially slidably assemble sliding block, the discharge plate left end inner radial is pressed in installing according to this from outside to inside Disk, spring lock block, interior platen, the spring lock block and sliding block are by positioning sleeve mounted in the stage clip between sliding block pylon and briquetting pylon Tensioning link, the discharge plate is central axial to install adjusting nut, the conical surface bar disk, institute for coordinating link by screw thread from left to right The nut end face for stating adjusting nut is contacted with interior platen block face, and the outer conical surface of the conical surface bar disk is slided with sliding block inclined-plane and connect Touch, the U-lag constitutes discharge plate type hole with the bar disk cambered surface and sliding block cambered surface of conical surface bar disk, so far constitutes double freedom modification Hole discharge plate.

The invention is axially moveable conical surface bar disk using rotating adjusting nut, is contacted with conical surface bar disk outer conical surface The sliding block of cooperation is moved radially due to the effect of stage clip along discharge plate, is made up of discharge plate U-lag, sliding block cambered surface and bar disk cambered surface Discharge plate type hole change the physical dimensions of type hole from two free degree directions, solve mechanical discharge plate type hole kernel texture The technical problem of shape and particle size adaptability.Meanwhile, the disk has that structure is novel, simple, reasonable, easy to operate, quality Reliably, the characteristics of applicability is wide.

Specific embodiment

The embodiment to the invention is described in detail below in conjunction with the accompanying drawings：

A kind of double freedom becomes type hole discharge plate, by chute 13 and raised line in the U-lag 18 that the circumference of discharge plate 1 is opened up Sliding block between 14 coordinates radially slidably assembling sliding block 2, during the left end inner radial of the discharge plate 1 is installed according to this from outside to inside Platen 3, spring lock block 4, interior platen 5, the spring lock block 4 is with sliding block 2 by positioning sleeve mounted in sliding block pylon 11 and briquetting post The tensioning link of stage clip 6 between platform 12, the discharge plate 1 is central axial to install the regulation spiral shell for coordinating link by screw thread from left to right Female 8, conical surface bar disk 7, the nut end face 9 of the adjusting nut 8 is contacted with interior platen block face 16, the conical surface bar disk 7 it is cylindrical The conical surface 17 and the sliding contact of sliding block inclined-plane 10, the U-lag 18 are constituted with the bar disk cambered surface 19 and sliding block cambered surface 15 of conical surface bar disk 7 Discharge plate type hole.

During operation, when needing to change discharge plate actual job type hole size, operating personnel pass through rotating adjusting nut 8, Coordinate the conical surface bar disk 7 for linking to be axially moveable relative to discharge plate 1 with its screw thread, in the U-lag 18 of discharge plate 1 radially The sliding block 2 of link is slided, because of the tension of stage clip 6 being sleeved between sliding block pylon 11 and briquetting pylon 12, makes the lower end of sliding block 2 Moment of outer conical surface 17 of sliding block inclined-plane 10 and conical surface bar disk 7 keep contacting, at this moment, with the axial movement of conical surface bar disk 7, Sliding block 2 is moved radially, therefore, by the bar disk cambered surface of the U-lag 18 of discharge plate 1, the sliding block cambered surface of sliding block 2 and conical surface bar disk 7 19 type holes for constituting are radially and the free degree direction of axial direction two changes the physical dimension size of type hole, meanwhile, made according to certain class The dependency structure dimensional parameters of thing or a certain kind of same crop, by rotating adjusting nut 8, set suitable discharge plate type hole Size.
