Description

The feed mechanism for seed of fast changeable indent type seed wheel
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of indent type seed wheel feed mechanism for seed.
Background technology
Breeding seeding operation is usually that a kind of sown area is little and the events in operation of broadcast seed variety and multi-size. For adapting to and meet the requirement of above-mentioned events in operation, cell-seed distributor need to 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 feed mechanism for seed structure problem, the replacing of indent type seed wheel is torn open very numerous and diverse, difficult with the process filled, and wastes time and energy, reduces the efficiency of breeding seeding operation.
Summary of the invention
The purpose of the invention is aiming at above-mentioned prior art Problems existing, in conjunction with being actually needed of breeding seeding operation, design provides the feed mechanism for seed of a kind of fast changeable indent type seed wheel, reach on feed mechanism for seed disassembling, assembling and replacing indent type seed wheel simply, purpose easily and efficiently.
The purpose of the invention is achieved in that and is fixedly mounted with left shell and right shell body on middle shell both sides respectively, constitutes and fill kind of a chamber between left shell and middle shell, constitutes transmission cavity between right shell body and middle shell; The rotating installation hairbrush wheel shaft of axis on the housing of left, center, right, rotating installation feed shaft on the right side, middle shell, hairbrush wheel shaft is connected by the drive system being arranged in transmission cavity with feed shaft; Power input sprocket and clear bristle brush wheel of planting fit on hairbrush wheel shaft admittedly, and described clear kind of bristle brush wheel is positioned at and fills kind of a chamber; It is positioned at described feed shaft and fills symmetry on kind of the end of chamber intracavity side and be fixedly installed convex key; Stairstepping through hole is offered at indent type seed wheel centre place, the small through hole wall of stairstepping through hole is oppositely arranged the keyway cooperated with convex key, on small through hole inner side end, being positioned at that large through-hole is internal symmetrical arranges positioning boss, described positioning boss misplaces 90 ° with adjacent keyway in a circumferential direction;Left shell A lower side wall portion offers dismounting through hole with the concentric position of 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, match with clear bristle brush wheel of planting, positioning boss coordinate with convex key contacts by indent type seed wheel on feed shaft circumferentially positioned; On described feed shaft medial end, be positioned at indent type seed wheel stairstepping through hole configuration spring base, in said pocket formula seed wheel end face outside and the concentricity position of stairstepping through hole be fixedly mounted with spring capping by screw, compression spring is installed between spring capping and spring base, the two ends of described compression spring contact cooperation with spring capping and spring base respectively, indent type seed wheel is axially positioned on feed shaft, so far constitutes the feed mechanism for seed 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 the keyway on indent type seed wheel and positioning boss and feed shaft, achieve indent type seed wheel fast assembling-disassembling in feed mechanism for seed and change operation, have simple in construction, novelty, rationally, indent type seed wheel disassembling, assembling and replacing is simple and easy, convenient, operate feature quick, time saving and energy saving, applied widely.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention embodiment is described in detail. The feed mechanism for seed of a kind of fast changeable indent type seed wheel, is fixedly mounted with left shell 1 and right shell body 3 respectively on middle shell 2 both sides, constitutes and fill kind of chamber 15 between left shell 1 and middle shell 2, constitutes transmission cavity 4 between right shell body 3 and middle shell 2; The rotating installation hairbrush wheel shaft 5 of axis 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 by the drive system 7 being arranged in transmission cavity 4 with feed shaft 8; Power input sprocket 6 and clear bristle brush wheel 16 of planting fit on hairbrush wheel shaft 5 admittedly, and described clear kind of bristle brush wheel 16 is positioned at and fills kind of chamber 15; It is positioned on the end filling kind of chamber 15 intracavity side symmetry at described feed shaft 8 and is fixedly installed convex key 19; Stairstepping through hole is offered at indent type seed wheel 14 centre place, the small through hole wall of stairstepping through hole is oppositely arranged the keyway 18 cooperated with convex key 19, on small through hole inner side end, being positioned at that large through-hole is internal 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 is offered 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, match with clear bristle brush wheel 16 of planting, positioning boss 17 contact with convex key 19 coordinate by indent type seed wheel 14 on feed shaft 8 circumferentially positioned;On described feed shaft 8 medial end, be positioned at indent type seed wheel 14 stairstepping through hole configuration spring base 12, said pocket formula seed wheel 14 end face outside is passed through screw 9 be fixedly mounted with spring capping 11 with the concentricity position of stairstepping through hole, compression spring 10 is installed between spring capping 11 and spring base 12, the two ends of described compression spring 10 contact cooperation with spring capping 11 and spring base 12 respectively, are axially positioned by indent type seed wheel 14 on feed shaft 8.
When feed mechanism for seed is changed the indent type seed wheel 14 of different size, after the hands of operator 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, the circumference that positioning boss 17 departs from convex key 19 is made to contact cooperation, when keyway 18 overlaps in a circumferential direction with convex key 19, indent type seed wheel 14 is pulled axially outward along feed shaft 8, makes indent type seed wheel 14 disassemble from feed shaft 8; With above-mentioned steps inverse operation, be about to change after indent type seed wheel 14 be fitted on feed shaft 8, complete quick-replaceable operation.
