Description
Technical field
The present invention relates to a kind of mechanical transmission, particularly a kind of seeder spacing in the rows speed changer.
Background technology
At present, the transmission speed ratio of sowing (fertilizer) machine spacing in the rows speed changer, mainly takes following three kinds of forms to enterRow is adjusted: adopt chain transmission, by changing chaindriven master and slave sprocket wheel to change gearratio, actual behaviourIn work, need dismounting sprocket wheel, increased subsidiary operation time, reduced operating efficiency; Adopt exposed gearTransmission, by changing driving and driven wheel diameter, to change gearratio, (while selecting machine to dispatch from the factory, producer providesDifferent equipment gears), in practical operation, want dismounting gear, there is equally aforesaid drawbacks; Adopt enclosed toothWheel transmission also has gear engaging device, can handle gear lever to realize different drive ratios in practical operation, realOn border, planting machinery operating speed lower (≤9km/h), also need not apply closed-type gear transmission, can makeBecome the unnecessary increase of manufacturing cost, (change tooth because closed-type gear transmission need to do time-based maintenance simultaneouslyWheel oil), also can cause the increase of peasant's use cost.
Summary of the invention
The object of the invention is to the defect for above-mentioned prior art, provide one can be convenient, fast,Stablize the seeder spacing in the rows speed changer of shift speed change.
Its technical scheme is: a kind of seeder spacing in the rows speed changer, comprises casing, fixes by bearing respectivelyPower input shaft on casing and power output shaft, the power input shaft in casing and power output shaftTwo ends are respectively equipped with left and right axle sleeve, on the power input shaft between left and right axle sleeve respectively by gear axle sleeveBe arranged at intervals with first-fourth speed driving gear, on power output shaft respectively by gear shaft room every settingThere is first-fourth speed driven gear, it is characterized in that: on described power input shaft and power output shaftLeft axle sleeve is equal in length, the right axle sleeve length on the right axle sleeve Length Ratio power output shaft on power input shaftGrow; Each gear axle sleeve on power input shaft equal in length, the each gear axle sleeve on power output shaftEqual in length and be greater than the length of the gear axle sleeve on power input shaft; On power input shaft the first-theBetween each gear axle sleeve one side between fourth gear driving gear and first grade of driving gear and left axle sleeve andBetween the gear axle sleeve and right axle sleeve of fourth speed driving gear, be also respectively equipped with and can plug and equal in lengthThe the first-the three fixed grade split bush; On described power input shaft, first-fourth speed driving gear is with movingFirst-fourth speed driven gear on power output shaft can corresponding engage, each grade of driving gear of corresponding engagementEquate with the number of teeth of driven gear and unequal, module and the facewidth.
Its technique effect is: seeder spacing in the rows speed changer of the present invention, only needs to determine shelves opening shaft by plugBe enclosed within the position on power input shaft, both can make the driving gear of required gear engage with driven gear,Can make again the driving gear of other each gear and driven gear stagger; Meanwhile, both can obtain requiredGearratio, has ensured again to only have corresponding a pair of driving gear to engage with driven gear, and can not produce unrestShelves phenomenon, thus avoid and solved prior art in shift speed change process, need dismounting casing, bearing,Gear shafts etc. are gear changing and loaded down with trivial details operation sequence more, has reduced subsidiary operation time, reduced simultaneously byThe damage that may bring to speed changer in disassembly process, has realized convenient, fast, stable speed changerShift speed change object, has also reduced manufacture and use cost, has extended the service life of speed changer.
