Description

A kind of double gearbox tractor

Technical field

This utility model relates to a kind of double gearbox tractor, relates to manufacture of agricultural machinery field, manufactures field particularly to agricultural tillage machinery.

Background technology

At present, roy-crop tractor used in agricultural production, there is walking and drive the function of rear output shaft, rear output shaft can drive rotary cultivator etc. to carry out ploughing work, but, the tractor power of Vehicles Collected from Market supply is being greatly improved, but rear output shaft only has two gear speed-regulating functions, rotating speed is the lowest and speed adjustable range is the least, tractor pulls up lame guarantee cultivating quality, the tractor cultivating quality that runs a good foot just is difficult to ensure that, if cultivating quality to be ensured just can only advance at a slow speed, a large amount of tractor output is so the most just wasted when farming, and this tractor must use special reversion rotary cultivator in case getting rid of before mud when slurry is mixed in farming paddy field, it is low to there is farming efficiency in the oldest money tractor, use the defect that limitation is big.

Summary of the invention

Farming efficiency in order to overcome existing tractor to exist is low, use the defect that limitation is big, this utility model provides a kind of double gearbox tractor, two groups of change speed gear boxes are connected with electromotor by the clutch of two groups of series connection respectively, one group of change speed gear box have multiple forward gear and one retreat gear and be connected with rear axle and realize many gears of tractor and move forward and backward, there is in described change speed gear box high low gear, another group change speed gear box also has multiple forward gear and one to retreat gear to be connected with rear output shaft and realize many gears of rear output shaft and rotate and reverse, described change speed gear box has high low gear.

This utility model solves the technical scheme of its technical problem use: the speed change box clutch connecting rear axle and the speed change box clutch being connected rear output shaft series connection, during let slip the clutch, rear axle gearbox clutch band driven input shaft elder generation and disengaged engine, with disengaged engine after rear output shaft clutch band driven input shaft, and when lifting clutch pedal, rear output shaft speed change box clutch band driven input shaft first engages with electromotor, engages with electromotor after rear axle gearbox clutch band driven input shaft；Rear axle gearbox rotates forward gear and one group of counter gear with many group forward gears and one group of reverse gear, rear output shaft change speed gear box with many groups；Make described tractor have rear output shaft many gears speed governing and reverse function, rear axle gearbox and rear output shaft change speed gear box and be provided with neutral gear.

The beneficial effects of the utility model are, tractor operation person can select suitable rear output shaft rotating speed according to ploughed ground condition, realize intensive cultivation, thus there is higher farming efficiency, and what when slurry is mixed in paddy field, use common rotary selection reversion gear got rid of before can reach and preventing mud mixes slurry effect, expands the range of tractor.

Below in conjunction with this accompanying drawing, this utility model is illustrated:

Accompanying drawing illustrates:

Fig. 2 is transmission assembly structural representation

1. front wheel supporting seat, 2. steering hydraulic oil cylinder, 3. front axle in Fig. 1,4. front driving wheel, 5. intermediate propeller shaft, 6. engine input shaft, 7. adpting flange after power transmission shaft, 8. universal joint, 9. rear axle, 10. transmission assembly, 11. rear output shafts, 12. rear output shaft adpting flanges, 13. rear drive sprockets, adpting flange before 14. intermediate propeller shafts.

1. electromotor in Fig. 2,2. engine flywheel, 3. clutch one, 4. power shaft one, 5. output shaft one gear, 6. output shaft one, 7. power shaft one gear, 8. center tooth wheels one, 9. counter gear, 10. output shaft two, 11. rear output shafts, 12. rear output shaft adpting flanges, 13. rear axle assemblies, 14. back axle spindles, 15. output shafts three, 16. reverse gears, 17. center tooth wheels two, 18. power shaft two gears, 19. power shafts two, 20. output shaft four gears, 21. output shafts four, 22. clutches two.

Detailed description of the invention:

nullIn Fig. 2，After electromotor 1 starts，Engine flywheel 2 drives clutch 1 and clutch 2 22 to rotate，After let slip the clutch, clutch 2 22 and clutch 1 separate in succession，Power shaft 1 and power shaft 2 19 stop operating，Tractor does not moves，Rear output shaft 11 does not rotates，When lifting clutch pedal to clutch one 3 position，Change speed gear box A starts working，Clutch 1 is combined with engine flywheel 2，Band driven input shaft 1 rotates，After the pin of change speed gear box A pushes a certain rotating forward gear，Power shaft 1 will drive output shaft 1 to rotate by the engagement of power shaft one gear 7 and output shaft one gear 5，So that rear output shaft 11 drags the tillage machinery being connected on rear output shaft flange 12 and rotates forward，When the pin of change speed gear box A pushes reversion gear，Power shaft 1 will be rotated with the drive output shaft 2 10 that engages of counter gear 9 by center tooth wheels 1，And then the tillage machinery making rear output shaft 11 band be automatically connected on rear output shaft adpting flange 12 reversely rotates；When clutch pedal is lifted to clutch 2 22 position, change speed gear box B starts working, clutch 2 22 band driven input shaft 2 19 rotates, after the pin of change speed gear box B pushes a certain forward gear, power shaft 2 19 is rotated with the drive output shaft 4 21 that engages of output shaft four gear 20 by output shaft two gear 18, and then drive back axle spindle 14 to drive rear axle assembly 13 to operate, tractor is made to advance, when change speed gear box B pin push reverse gear gear time, power shaft 2 19 will be rotated backward with the drive output shaft 3 15 that engages of reverse gear 16 by center tooth wheels 2 17, and then drive back axle spindle 14 to drive rear axle assembly 13 to operate, tractor is made to fall back.
