Fig. 3 is hole spiral and patterns under short at the D of figure (1) to view.
Fig. 4 is the another kind of version of hole spiral expressed among Fig. 2.
Fig. 5 is the master rotor schematic diagram with hole spiral and blade screw.
Among the figure: 1, grass outlet; 2, grass-removing fan; 3, master rotor; 4, choke circle; 5, shell; 6, blade screw; 7, concave grate; 8, annular baffle; 9, hole spiral; 10, patterns under short; 11, feeding mouth; 12, belt pulley; 13, frame; 14, the mouth of putting out cereal; 15, thin round steel; 16, peach ring-type; 17, circular rings.
With reference to accompanying drawing hole spiral axial-flow thresher, it has master rotor (3), links to each other with housing by bearings at both ends, and be supported on the support (13), be fixed with several pieces grass-removing fans (2) (cylinder is open type) herein on the top of master rotor, the middle part is fixed with choke circle (4) (cylinder is enclosed) herein, and the bottom of cylinder is open type; The rotation direction of cylinder spiral is decided according to the rotation direction of mating power.Corresponding to the direction of rotation of master rotor (3), the rotation direction of spiral should satisfy millet straw and move upward simultaneously in the process of rotation.Among spiral in hole leaf (9) Fig. 1 double dot dash line partly be hole spiral (9) with the circumference of the occupied part periphery of blade screw (6) on the sieve plate of configuration one concave grate (7) or other structure.On concave grate (7), have feeding mouth (11).
Accompanying drawing 2 has mainly reflected being connected and difference of blade screw (6) and spiral with holes (9).Spiral with holes (9) is by some peach shape rings (16), four schematic diagrames only draw in the accompanying drawing, spiral with holes (9) coils on the circumference of master rotor (3), till this spiral with holes (9) begins to be wound into blade screw (6) joint from the surperficial bottom of master rotor (3), the outer most edge of spiral with holes is coiled in the outer rim that peach shape ring has (16) by a thin round steel (15), and is welded and fused with it.Lead on the circumference that rolls (3) and be furnished with spiral with holes (9), have several eyelets on the blade of spiral with holes (9), and can find the minimum continuous helix that is no less than on the surface of spiral outer most edge.
Be furnished with blade screw (6) between the lower edge of spiral with holes (9) and grass-removing fan (2), this spiral lower end and spiral with holes (9) smoothly join, and the upper end links to each other with grass-removing fan (2) lower edge.The outer most edge helix of blade screw (6) should be a continuously smooth.
In order to simplify technology, spiral with holes (9) described in the figure (2), also can adopt several annulus (17) assembly welding among the figure (4) to form by round steel circle system, or adopt that blanking several holes eye forms on the steel plate helical blade, it is continuous no matter adopting the helix of spiral with holes (9) outer most edge which kind of way makes.
Blade screw (6) adopts the sheet metal blanking to form, the shape that the shape behind the mounted blade is same as helical blade in the routine techniques after launching, i.e. and an entity or a part between two concentric circles, blade surface does not have eyelet.
Cylinder (3) bottom is rigidly connected with cylinder (3) at hole spiral (9) non-working surface one side configuration several piece patterns under short (10), patterns under short (10), sees accompanying drawing (1).The length direction of patterns under short (10) should be parallel to the axis of cylinder (3), and the one end links to each other with the non-working surface of hole spiral (9), sees figure (3).
The top of shell (5) has grass outlet (1), and the middle part has feeding mouth (11), and the bottom has put out cereal mouthful (14), and the annular space between concave grate (7) and the shell (5) utilizes annular baffle (8) that the space on its top is separated.
Power is by belt pulley (14) input, and the ω direction among the figure (2) is the direction of rotation of thresher.
The contrast accompanying drawing is described in detail the operation principle of thresher below: enter the interior crop of machine under the effect of helix drum (3); repeated multiple times is beaten by the action of centrifugal force throwing; crumple and threshing; and cane moves upward in this course, is dished out outside the machine by grass-removing fan during to the bottom of grass-removing fan (2).Because the blade screw (6) that distributes on cylinder (3) circumference cooperates choke circle (4) effect, make to move to that grain remaining in the cane on top is unlikely to be taken out of outside the machine by airstream suction, and under action of centrifugal force, be separated to outside the concave grate (7).In the central passage of cylinder (3),, can make foreign material suction that cylinder (3) bottom threshing section produced be blown grass outlet (1) like this to the central passage of cylinder (3) because the effect of grass-removing fan (2) will produce one stronger air-flow and move upward.Vacuum suction effect owing to central passage makes that throwing to the outer foreign material of concave grate has alleviated the burden of cleaning in a large number in this course.
Hole spiral (9) is because blade surface has some eyelets, and therefore this helical blade can not only play the effect of axially sending grass more satisfactorily, can tangentially hit the grain ear in the cane simultaneously.In addition owing to this helical blade increases with the friction of the helical blade in the friction ratio routine techniques of straw (blade surface atresia) with straw, straw peripheral speed in the process of threshing is increased, quickened seed and come off thereby increased the centrifugal force that acts on the grain ear; Moreover since eyelet act on cane when moving upward, the grain in the cane can fall from the hole and be separated outside the concave grate, thereby and is unlikelyly taken upwards with cane out of machine is outer have been reduced the grain in the cane and carry secretly.Being separated the outer grain of concave grate discharges in lower housing portion under the effect of gravity.
Can improve the extracting ability enhancing threshing effect of cylinder (3) at the several piece patterns under short (10) of hole spiral (9) non-working surface one side configuration.
Advantage:
1, since hole spiral to the impact strength of crop a little less than, the threshing time is longer, therefore in that to satisfy under the prerequisite of threshing performance percentage of damage less, particularly broken grass is starkly lower than existing axial-flow thresher when dried crop threshing.
2, because " stranding plait " phenomenon that the continuity of the outer rim helix of hole spiral makes present axial-flow thresher produce in the wet threshing of growing grass makes cylinder twine stifled defect fundamentally achieves a solution.Show according to interrelated data: at present axial-flow thresher reaches 60 centimetres and crop at grass and easily produces " stranding plait " phenomenon when wet; And present embodiment reaches 90 centimetres and crop at grass and had not also found above-mentioned phenomenon when wet.
3, because air channel, center sucking action makes in the emersion object percentage of impurity lower, the emersion object cleannes are further improved and additional investment also seldom.
4, because hole spiral has stronger centrifugation, therefore be entrained in the millet straw grain seldom, complete machine threshing percent of loss is very low.
5, compare with existing vertical axial-flow thresher, under the prerequisite that guarantees the emersion object cleannes, make positive machine structure length shorten 1/3～1/4, thereby alleviated construction weight and cost.
6, because the axial length between feeding mouth and the power input pulley is shorter, therefore when being equipped with combine, the ceding of Taiwan can be shortened to length between the thresher feeding mouth, can reduce cost.
Arrow code name cane in the accompanying drawing 1 (* →), grain husk chaff (→), grain (0 →) is because the effect of grass-removing fan (2), produce the air-flow that generally makes progress in the air channel, center, and cylinder is formed (being open type) by several width of cloth bars, therefore the crop that passes through between hole spiral (9) and concave grate (7) is except moving upward, some broken cane, the grain husk chaff, seed is discharged concave grate (7) periphery, some broken cane in addition, the grain husk chaff is because the updraft sucking action in air channel, center, move upward in company with this air-flow, at last by outside grass-removing fan (2) the discharge machine.
