Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of grain separator.
Background technology
Used thresing machine is to be equipped with the individual layer V-arrangement with fixing hole shape and size perforations on material bin bottom to fix
Sieve, will be blended in cereal using above-mentioned sieve aperture and avenge powder and drop outside broken or hair enzyme seed discharge machine, to ensure that postorder takes off
The quality of grain separating cleaning operation., i.e., can not basis because the sieve hole size that existing V-arrangement is fixed in sieve is unadjustable
Snow powder amount number and drop seed reclaim needs be adjusted, operation adaptability is poor.If changed on material bin bottom
The V-arrangement of different sieve apertures fixes sieve, and not only accessory is more, and cost is high, and changes difficult, and operation difficulty is big, and operating efficiency is low.Separately
Outside, the sieve aperture side wall that existing individual layer V-arrangement is fixed in sieve and upper surface connecting portion are rectangular-shaped, under the cereal kernel dropped
G seed phenomenons easily occur when falling, has aggravated the degree of crushing of seed, has improved percentage of damage.
The content of the invention
The problem of purpose of the invention exists aiming at above-mentioned prior art, designs a kind of thresing machine of new construction
Material bin adjustable sieve holes mechanism, reaches and realizes the adjustable change of screening area size in sieve, meets different with separation is adapted to
The powder amount containing snow and seed amount operation of dropping need, reduce and reduce the purpose of G seed rates.
What the purpose of the invention was realized in：Thresing machine material bin adjustable sieve holes mechanism includes material bin and band
The V-arrangement for having gravity flow screen film perforation fixes sieve, and the V-arrangement is fixed sieve and fitted over admittedly on material bin bottom, and sieve is fixed in the V-arrangement
Contain on outside bottom side covering and can lateral adjustments movement the equipped V-arrangement movement sieve with diaphragm film perforation, the movement
Covering cooperation in an overlapping or is blocked in sieve hole with gravity flow screen film perforation, and pull bar, screw mandrel are fixedly mounted with V-arrangement movement sieve side portion
Axial direction, radial positioning, circumference are rotatably arranged on the outside of material bin bottom side, and the screw mandrel is parallel to each other with pull bar, in institute
The fitting nut plate being axially movable on screw mandrel is stated, the nutplate is fixedly connected with pull bar, and handle is packed on screw mandrel end.
The invention use V-arrangement fix on the downside of sieve be equipped with outside can the V-arrangement of transverse shifting regulation move sieve
Combining structure, the shielding mode that sieve hole in sieve is fixed in the sieve hole in sieve to V-arrangement is moved using V-arrangement, is realized to V-arrangement
The big minor adjustment of the logical area of fixation sieve aperture leakage in fixed sieve, the discharge operation for meeting different snow powder amounts and the seed amount that drops will
Ask, with structure novelty, reasonable, simple, regulation simple and convenient, adaptable, performance is good, operation quality is high, G seeds
The characteristics of rate is low.

Embodiment
The invention embodiment is described in detail below in conjunction with the accompanying drawings.A kind of thresing machine material bin adjustable sieve
Holes mechanism includes material bin 1 and the V-arrangement with gravity flow screen film perforation 8 fixes sieve 2, and the V-arrangement fixes sieve 2 and fits over material bin admittedly
On 1 bottom, the V-arrangement fix contain on outside sieve 2 bottom side covering and can the equipped of lateral adjustments movement carry diaphragm
The V-arrangement movement sieve 7 of film perforation 9, the diaphragm film perforation 9 in an overlapping or blocks covering cooperation with gravity flow screen film perforation 8, in the V
Pull bar 3 is fixedly mounted with the shape movement sidepiece of sieve 7 one, the axial direction of screw mandrel 6, radial positioning, circumference are rotatably arranged on the bottom side of material bin 1
On outside, the screw mandrel 6 is parallel to each other with pull bar 3, the fitting nut plate 4 being axially movable on the screw mandrel 6, the nut
Plate 4 is fixedly connected with pull bar 3, and handle 5 is packed on the end of screw mandrel 6.The hole of gravity flow screen film perforation 8 fixed in the V-arrangement in sieve 2
Wall upper periphery is provided with circular arc chamfering.
During operation, the grain ear for treating threshing is sent into material bin 1, in grain ear the snow powder of entrainment and the seed that drops successively from
V-arrangement is fixed to be fallen into outside discharge machine in the diaphragm film perforation 9 on the gravity flow screen film perforation 8 in sieve 2 and V-arrangement movement sieve 7.When need adjust
When size is led in the leakage of knotter screen film perforation, handle 5 is rotated with hand, the drive nut plate 4 of screw mandrel 6 of rotation is moved axially, and pass through drawing
Bar 3 laterally pulls V-arrangement movement sieve 7 to fix sieve 2 relative to V-arrangement and moved, and changes and adjusts the gravity flow screen film perforation 8 and mobile
The mutual overlapping and shielded area in sieve hole 9, realizes the change of the logical area of sieve hole leakage, completes regulation.The hole wall of gravity flow screen film perforation 8
The circular arc chamfering of upper periphery, reduces and avoids and damage destruction to the G for the seed that drops.
