Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of indent type seed wheel seeding unit.
Background technology
Normally a kind of sowing area of breeding seeding operation little and broadcast the events in operation of seed variety and multi-size.For adapting to and meet the requirement of above-mentioned events in operation, cell-seed distributor need be equipped with the indent type seed wheel of multiple different shaped hole dimension and structure.During operation, different according to breeding seed, change corresponding indent type seed wheel.Due to existing seeding unit structure problem, the replacing of indent type seed wheel is torn open with the process filled very numerous and diverse, difficult, wastes time and energy, reduces the efficiency of breeding seeding operation.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, in conjunction with the actual needs of breeding seeding operation, design provides a kind of seeding unit of fast changeable indent type seed wheel, to reach on seeding unit disassembling, assembling and replacing indent type seed wheel simply, object easily and efficiently.
The object of the invention is achieved in that and is fixedly mounted with left shell and right shell body respectively on middle shell both sides, forms and fills kind of a chamber, between right shell body and middle shell, form transmission cavity between left shell and middle shell; Axis rotating installation hairbrush wheel shaft on the housing of left, center, right, rotating installation feed shaft on the right side, middle shell, hairbrush wheel shaft is connected with feed shaft by the transmission system be configured in transmission cavity; Power input sprocket and clear brush-wheel of planting fit on hairbrush wheel shaft admittedly, and described clear kind of brush-wheel is positioned at and fills kind of a chamber; Be positioned at described feed shaft and fill symmetry on kind of the end of side, chamber chamber and be fixedly installed convex key; In indent type seed wheel centre, place offers stairstepping through hole, the small through hole wall of stairstepping through hole is oppositely arranged the keyway cooperatively interacted with convex key, on small through hole inner side end, be positioned at that large through-hole is inner symmetrical arranges positioning boss, described positioning boss misplaces 90 ° with adjacent keyway in a circumferential direction; In left shell A lower side wall portion, dismounting through hole is offered at concentric position with feed shaft, indent type seed wheel is arranged on feed shaft end through dismounting through hole and convex key, and be positioned at and fill kind of a chamber, with clearly plants brush-wheel and matches, positioning boss coordinates with convex key contacts locates circumferential on feed shaft for indent type seed wheel; On described feed shaft medial end, the stairstepping through hole that is positioned at indent type seed wheel configures spring base, spring capping is fixedly mounted with by screw in described indent type seed wheel end face outside, with the concentricity position of stairstepping through hole, setting pressure spring between spring capping and spring base, the two ends of described compression spring contact with spring base with spring capping respectively and coordinate, by indent type seed wheel axial location on feed shaft, so far form the seeding unit of fast changeable indent type seed wheel.
Dismounting through hole is offered in the invention on left shell, adopt the convex key fit structure successively on keyway on indent type seed wheel and positioning boss and feed shaft, achieve the fast assembling-disassembling of indent type seed wheel in seeding unit and change operation, have that structure is simple, novel, rationally, indent type seed wheel disassembling, assembling and replacing is simple and easy, convenient, operate feature quick, time saving and energy saving, applied widely.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.A seeding unit for fast changeable indent type seed wheel, middle shell 2 both sides are fixedly mounted with left shell 1 and right shell body 3 respectively, form and fill kind of chamber 15, form transmission cavity 4 between right shell body 3 and middle shell 2 between left shell 1 and middle shell 2; Axis rotating installation hairbrush wheel shaft 5 on left, center, right housing 1,2,3, rotating installation feed shaft 8 on the right side, middle shell 3,2, hairbrush wheel shaft 5 is connected with feed shaft 8 by the transmission system 7 be configured in transmission cavity 4; Power input sprocket 6 and clear brush-wheel 16 of planting fit on hairbrush wheel shaft 5 admittedly, and described clear kind of brush-wheel 16 is positioned at and fills kind of chamber 15; Be positioned at symmetry on the end filling side, kind of chamber 15 chamber at described feed shaft 8 and be fixedly installed convex key 19; In indent type seed wheel 14 centre, place offers stairstepping through hole, the small through hole wall of stairstepping through hole is oppositely arranged the keyway 18 cooperatively interacted with convex key 19, on small through hole inner side end, be positioned at that large through-hole is inner symmetrical arranges positioning boss 17, described positioning boss 17 misplaces 90 ° with adjacent keyway 18 in a circumferential direction; Left shell 1 A lower side wall portion offers dismounting through hole 13 with the concentric position of feed shaft 8, indent type seed wheel 14 is arranged on feed shaft 8 end through dismounting through hole 13 and convex key 19, and be positioned at and fill kind of chamber 15, with clearly plants brush-wheel 16 and matches, positioning boss 17 contacts with convex key 19 to coordinate and locates circumferential on feed shaft 8 for indent type seed wheel 14; On described feed shaft 8 medial end, the stairstepping through hole that is positioned at indent type seed wheel 14 configures spring base 12, spring capping 11 is fixedly mounted with by screw 9 in described indent type seed wheel 14 end face outside, with the concentricity position of stairstepping through hole, setting pressure spring 10 between spring capping 11 and spring base 12, the two ends of described compression spring 10 contact with spring base 12 with spring capping 11 respectively and coordinate, by indent type seed wheel 14 axial location on feed shaft 8.
When seeding unit is changed the indent type seed wheel 14 of different size, after the hand of operating personnel holds indent type seed wheel 14 by dismounting through hole 13, rightabout along seeding operation direction of rotation rotates indent type seed wheel 14 on feed shaft 8, positioning boss 17 disengaging is contacted with the circumference of convex key 19 coordinate, when keyway 18 overlaps in a circumferential direction with convex key 19, indent type seed wheel 14 is axially pulled out along feed shaft 8, indent type seed wheel 14 is disassembled from feed shaft 8; With above-mentioned steps inverse operation, be about to the indent type seed wheel 14 after changing and be fitted on feed shaft 8, complete quick-replaceable operation.
