This middle-size and small-size sprinkler with reel gearbox on being mounted on reel sprinkling irrigation machine when working, before operation of spraying, Make sliding shift seat 25 that sliding gear lever 26 be driven to be moved to along guide groove 221 by operation shift rod and is located remotely from gear teeth I 24 neutral gear position is taken turns, motor or eddies of water wheel shaft drive input shaft 1 to rotate after motor or hydroturbine starting, input shaft driving cog Wheel 11 makes to slide the rotation of variable block transmission shaft 2 by variable block transmission shaft driven gear 23, and sliding variable block transmission shaft 2 drives sliding to change It rotates and transmission gear I 24 during block seat 25 and sliding 26 coaxial rotating of gear lever relative to transmission gear I 24 It does not rotate, steel ball 212 can not transmit power and be limited in steel by transmission gear I 24 during sliding variable block transmission shaft 2 rotates In pearl receiving opening 211, capstan winch, that is, idle running, sprinkler wagon of sprinkler is released and PE is pulled to manage to the position that need to spray at this time；Spray When filling operation, operation shift rod makes sliding shift seat 25 drive sliding gear lever 26 along guide groove 221 to transmission gear I 24 Direction axial movement, sliding gear lever 26 move axially gear distance during its abut against step 261 by arc transition by Steel ball 212 is jacked up and is positioned outward along steel ball receiving opening 211, and steel ball 212 is caught in arc groove 241, and sliding variable block passes Moving axis 2 realizes that connection, sliding variable block transmission shaft 2 drive the rotation of transmission gear I 24 to realize transition transmission with transmission gear I 24 Axis 3 rotates, and transition transmission shaft 3 drives output shaft 4 to rotate output power drive capstan winch backrush and realizes by output shaft transmission gear Recycle PE tank；PE pipe recycling speed as needed need to only elapse operation shift rod to different gears i.e. when carrying out speed change Can, it is slid during gear shift operation and abuts against step 261 during gear lever 26 moves axially successively by sliding variable block biography The steel ball 212 of axially different position on moving axis 2 abuts against steel ball 212 during step 261 passes through and is abutted against step 261 and first push up It rises, fall again afterwards, rest in the gear positions of needs until abutting against step 261 and the steel ball of the position 212 is jacked up and positioned, Sliding variable block transmission shaft 2 is to drive the transmission gear I 24 at this to rotate to realize variable block speed change.
It is slid during due to gear shift operation during gear lever 26 moves axially and abuts against step 261 successively by sliding Move axially different position on variable block transmission shaft 2 steel ball 212 can make steel ball 212 abutted against step 261 first jacks up, it is rear fall again, And then output shaft 4 can follow interval gear shifting operation during will cause variable block, follow interval speed change, same for avoid output shaft 4 When reduce neutral gear capstan winch idle running when load, as a further improvement of the present invention, the transition transmission shaft 3 or output It is additionally provided with clutch control mechanism on axis 4, transition transmission shaft 3 or output shaft can be made by controlling clutch control mechanism in speed-change process 4 separate with sliding 2 teeth portion of variable block transmission shaft and realize that avoid output shaft 4 follows interval speed change, while realizing and reducing neutral gear capstan winch Load when idle running, convenient for capstan winch idle running sprinkler car traction PE pipe.
In order to realize that transmission gear I 24 is more securely driven by sliding variable block transmission shaft 2, further change as of the invention Into scheme, arc groove 241 on the transmission gear I 24 is two pieces, the steel ball along central axes center symmetric setting Receiving opening 211 is two rows along central axes center symmetric setting, and steel ball 212 is along central axes symmetry direction in variable block transmission process It goes up while being ejected and be caught in arc groove 241, and then realize and be more securely driven.
In order to realize sliding shift seat 25 and slide being bonded of gear lever 26, prevent that sliding from shifting gears seat 25 and sliding is changed 26 unbalance loading of bar, while realizing convenient for connection installation, as a further improvement of the present invention, the connecting pin setting exists Slide outer surface and sliding shift seat that sliding control section 22 is run through in the diametrical direction of the gear lever 26 and both ends of connecting pin 25, it is two that the both ends that the guide groove 221 is correspondingly connected with pin, which are symmetrical arranged, and the connecting pin of diametrical direction setting, which is realized, to be slided It moves shift seat 25 and slides being easily installed while being bonded for gear lever 26.
In order to guarantee steel ball 212 can smoothly be abutted against step 261 jack up, abut against step 261 pass through after can smoothly fall Under, as a further improvement of the present invention, it is described abut against step 261 in axial direction on two there is arc transition The arc radius for abutting against face and steel ball 212 radius size cooperate.
In order to make steel ball 212 sliding 2 rotary course of variable block transmission shaft in retraction always in steel ball receiving opening 211 Portion, and then the service life touching limitation, extend steel ball 212 of the marginal position to steel ball 212 of arc groove 241 is reduced, make Outer surface for further improvement of the present invention scheme, the sliding gear lever 26 is equipped with magnetic coating, and magnetic coating can be right Steel ball 212 is adsorbed, and then realizes that the retraction always in sliding 2 rotary course of variable block transmission shaft of steel ball 212 is accommodated in steel ball Inside through-hole 211.
In order to reduce the setting of the gear on transition transmission shaft 3, save cost, as a further improvement of the present invention, Transition transmission shaft driven gear on the transition transmission shaft 3 is one of them in multiple transmission gears II 31.
This middle-size and small-size sprinkler with reel gearbox is directly socketed in hollow tube due to being equipped with sliding variable block transmission shaft 2 Multiple and different transmission ratios on the sliding variable block transmission shaft 2 of shape structure, axially position installation transmission gear I 24 can be in tooth It takes turns and is rotated freely on supporting section 21, transmission gear I 24 is realized and slided by arc groove 241, steel ball 212 and sliding gear lever 26 It moves variable block transmission shaft 2 to connect or disconnect, i.e., is jacked up steel ball 212 using abutting against face by abutting against the arc transition of step 261 Mode realize that steel ball 212 is connected in arc groove 241 and realize that transmission gear I 24 is connect with variable block transmission shaft 2 is slid, therefore Structure is simple, variable speed operation is convenient, and volume is relatively small, compact-sized, space hold is smaller；Due to the change of different drive ratios Fast gear I 24 can be set side by side along sliding 2 axial direction of variable block transmission shaft as more than one piece, therefore control transmission gear I 24 along axis Width dimensions on direction can realize biggish shift range, and then realize and guarantee higher transmission effect under lesser volume Rate, especially suitable for middle-size and small-size reel sprinkling irrigation machine.
