This reel sprinkling irrigation machine sliding manual transmission when working on the reel sprinkling irrigation machine, in sprinkling irrigation operation Before, change is located remotely from by operating gear lever to make sliding gearshift seat 25 drive sliding gear level 26 to be moved to along guide groove 221 The neutral position of fast gear I 24, motor or hydroturbine start rear motor or eddies of water wheel shaft drives input shaft 1 to rotate, and input shaft is passed Moving gear 11 rotates sliding shift power transmission shaft 2 by shift transmission shaft driven gear 23, and sliding shift power transmission shaft 2 drives to be slided Rotate relative to change-speed gearing I 24 during moving gearshift 26 coaxial rotating of seat 25 and sliding gear level, and gear teeth Take turns I 24 not rotate, during sliding shift power transmission shaft 2 rotates, steel ball 212 cannot transmit power by the restriction of change-speed gearing I 24 In steel ball receiving opening 211, now capstan winch is idle running, sprinkler wagon of sprinkler is released and pulls PE to manage to position of need to spraying Put；During sprinkling irrigation operation, operation gear lever makes sliding gearshift seat 25 drive sliding gear level 26 along guide groove 221 to change-speed gearing During I 24 direction axial movement, the axial movement gear distance of sliding gear level 26, which leans step 261 by circular arc mistake Cross and steel ball 212 along 211 outside jack-up of steel ball receiving opening and is positioned, steel ball 212 is snapped in arc groove 241, sliding becomes Shelves power transmission shaft 2 is connected with the realization of change-speed gearing I 24, sliding shift power transmission shaft 2 drives the rotation of change-speed gearing I 24 to realize transition Power transmission shaft 3 rotates, and transition power transmission shaft 3 drives the rotation output power of output shaft 4 to drive capstan winch backrush by output shaft travelling gear Realize reclaiming PE tanks；PE pipes as needed are reclaimed , sliding gear level 26 leans step 261 during moving axially and sequentially passes through sliding shift during gear shift operation The steel ball 212 of axially different position on power transmission shaft 2, leans the steel ball 212 during of step 261 and is leaned step 261 first Jack-up, it is rear fall again, until leaning step 261 rests in the gear positions of needs and by 212 jack-up of steel ball of the position and calmly Position, sliding shift power transmission shaft 2 drive the change-speed gearing I 24 at this to rotate and realize shift speed change.
During due to gear shift operation, sliding gear level 26 leans step 261 during moving axially and sequentially passes through cunning The steel ball 212 for moving axially different position on shift power transmission shaft 2 can make steel ball 212 be leaned 261 first jack-up of step, be fallen again afterwards, And then output shaft 4 can follow interval gear shifting operation during causing shift, interval speed change, same is followed for avoid output shaft 4 When reduce load when neutral gear capstan winch dallies, as a further improvement on the present invention scheme, described transition power transmission shaft 3 or output Clutch control mechanism is additionally provided with axle 4, in speed-change process, transition power transmission shaft 3 or output shaft can be made by controlling clutch control mechanism 4 are separated with 2 teeth portion of sliding shift power transmission shaft and realize that avoid output shaft 4 follows interval speed change, while realizing reducing neutral gear capstan winch Load during idle running, it is easy to capstan winch idle running sprinkler car traction PE pipes.
In order to realize that change-speed gearing I 24 is more securely driven by sliding shift power transmission shaft 2, as further changing for the present invention Enter scheme, the arc groove 241 on described change-speed gearing I 24 is set to two pieces, described steel ball along axis centrosymmetry Receiving opening 211 is set to two rows along axis centrosymmetry, and in shift transmission process, steel ball 212 is along axis symmetry direction Upper being ejected simultaneously is snapped in arc groove 241, and then realizes more securely being driven.
In order to realize the firm connection of sliding gearshift seat 25 and sliding gear level 26, prevent sliding from shifting gears seat 25 and sliding is changed 26 unbalance loading of pin, while realizing being easy to connection to install, scheme as a further improvement on the present invention, described connecting pin are arranged on In the diametric(al) of sliding gear level 26, and connecting pin two ends through sliding control section 22 outer surface and sliding gearshift seat 25, the two ends of the described correspondence connecting pin of guide groove 221 are symmetrical arranged as two, and the connecting pin that diametric(al) is arranged is realized sliding It is easily installed while the firm connection for moving gearshift seat 25 and sliding gear level 26.
In order to ensure that steel ball 212 can smoothly be leaned 261 jack-up of step, lean step 261 and smoothly can fall after Under, scheme as a further improvement on the present invention is described to lean two that step 261 in axial direction goes up and have arc transition The radius size of the arc radius for leaning face and steel ball 212 coordinate.
In order that steel ball 212 in 2 rotary course of sliding shift power transmission shaft retraction all the time in steel ball receiving opening 211 Portion, and then marginal position the touching restriction, extending the service life of steel ball 212 to steel ball 212 of arc groove 241 is reduced, make For further improvement of the present invention scheme, the outer surface of described sliding gear level 26 is provided with magnetic coating, and magnetic coating can be right Steel ball 212 is adsorbed, and then realizes that the retraction all the time in 2 rotary course of sliding shift power transmission shaft of steel ball 212 is accommodated in steel ball Inside through hole 211
Arrange to reduce the gear on transition power transmission shaft 3, cost-effective, scheme as a further improvement on the present invention, Transition transmission shaft driven gear on described transition power transmission shaft 3 is one of them in multiple change-speed gearings II 31.
This reel sprinkling irrigation machine sliding manual transmission is due to being provided with sliding shift power transmission shaft 2, and is directly socketed in hollow The change-speed gearings I 24 that multiple different drive ratios, axially position on the sliding shift power transmission shaft 2 of tubular structure is installed can be Rotate freely on gear supporting section 21, change-speed gearing I 24 by arc groove 241, steel ball 212 and sliding gear level 26 realize with The connection or disconnection of sliding shift power transmission shaft 2, i.e. employing lean face by the arc transition for leaning step 261 and push up steel ball 212 The mode for rising realizes that steel ball 212 is connected in arc groove 241 and realizes that change-speed gearing I 24 is connected with sliding shift power transmission shaft 2, because This simple structure, variable speed operation are convenient, and volume is relatively small, compact conformation, space hold are less；Due to different drive ratios Change-speed gearing I 24 can be set up in parallel as more than one piece along 2 axial direction of sliding shift power transmission shaft, therefore controls I 24 edge of change-speed gearing Width dimensions on axial direction are capable of achieving larger shift range, and then realize ensureing higher transmission effect under less volume Rate, is particularly well-suited to middle-size and small-size reel sprinkling irrigation machine.
