During use, see also Fig. 5～shown in Figure 14, when the carrier wheel 62 of second turning lever 7 on first 6 passed first gear to cutter mechanism (as shown in Figure 8), the gear teeth of its carrier wheel 62 are meshed with first driven gear 41 and second driven gear 42 of jack shaft 4, clutch gear 61 on first 6 then is positioned at the alcove 620 of carrier wheel 62, the gear teeth of described clutch gear 61 are draw-in groove 621 location that are held in the alcove 620, when input shaft 3 is subjected to the external force driven rotary, first driving gear 31 on the input shaft 3, second driving gear 32 and the 4th driving gear 34 can drive and the jack shaft 4 of engagement on second driven gear 42, the 3rd driven gear 43, the 4th driven gear 44 and the 5th driven gear 45 rotate, 4 of jack shafts are driven to rotate thereupon, and the carrier wheel 62 on be meshed with first driven gear 41 of jack shaft 4 and second driven gear 42 first 6 also is driven to rotate, carrier wheel 62 and drive with the clutch gear that engages 61 rotations, first 6 rotations thereupon, and drive driving gear 64 rotations, 64 drives of described driving gear are located at driven gear 27 rotations in the housing 2,27 of described driven gears can drive the associated mechanisms start of cutter, cutter mechanism just is when first gear changes, because of the carrier wheel 62 on first 6 is first driving gear, 31 interlocks by the little number of teeth, so cutter is to be rotation at a slow speed, the wheel of described farm machinery then relies on the rotation of jack shaft 4 to drive carrier wheel 47 rotations, 47 drives of described carrier wheel and the output shaft 8 of engagement on 81 rotations (as shown in figure 12) of first gear, 81 rotations of described first gear, 8 rotations thereupon of its output shaft, but 8 driven wheel submechanisms of output shaft just change, and described farm machinery is advanced; The rotating speed of wheel then can move the carrier wheel on the jack shaft 4 47 via stirring of first turning lever 5, make described carrier wheel 47 and first gear 81 of output shaft 8 be meshed and be low-speed running, and when carrier wheel 47 moves between first gear 81 of output shaft 8 and second gear 82 (as shown in figure 13), 8 of its output shafts are not driven, wheel mechanism then can not turn round, when carrier wheel 47 moves to (as shown in figure 14) when being meshed with second gear 82, its wheel then is and runs up.
When the carrier wheel 62 of second turning lever 7 on first 6 passed second gear to cutter mechanism (as shown in Figure 9), the gear teeth of its carrier wheel 62 are meshed with second driving gear 32 of input shaft 3 and second driven gear 42 of jack shaft 4, clutch gear 61 on first 6 then breaks away from the alcove 620 of carrier wheel 62, the gear teeth of described clutch gear 61 no longer are held in the draw-in groove 621 of alcove 620, when input shaft 3 is subjected to the external force rotation, 62 of carrier wheels on be meshed with second driving gear 32 on the input shaft 3 and second driven gear 42 on the jack shaft 4 first 6 are driven to rotate, carrier wheel 62 is not because of engaging with clutch gear 61,62 idle running on first 6 of described carrier wheel, first 6 are not changeed, cutter mechanism then is halted state when second gear, the wheel of described farm machinery then relies on the counterrotating of jack shaft 4 and drives carrier wheel 47 counterrotatings, 47 drives of described carrier wheel and output shaft 8 counter-rotatings of engagement, but 8 driven wheel submechanisms of output shaft reverse, and farm machinery is retreats the state of advancing.
When the carrier wheel 62 of second turning lever 7 on first 6 passed third gear to cutter mechanism (as shown in figure 10), the gear teeth of its carrier wheel 62 are meshed with second driving gear 32 and the 3rd driving gear 33 of input shaft 3, and the clutch gear 61 on first 6 is the alcoves 620 that break away from carrier wheel 62, when being subjected to the external force rotation, input shaft 3 then drives jack shaft 4 rotations, in its first 6 no longer are held in carrier wheel 62 because of clutch gear 61 the alcove 620, when being driven, carrier wheel 62 only can on first 6, dally, its first 6 can't be rotated, cutter mechanism still is the state of shutting down when third gear, the wheel of its described farm machinery then relies on the rotation of jack shaft 4 to drive carrier wheel 47 rotations, 47 of described carrier wheels drive output shaft 8 just to be changeed, but 8 driven wheel submechanisms of described output shaft just change, and described farm machinery is advanced.
Moreover, when the carrier wheel 62 of second turning lever 7 on first 6 passed fourth speed position to cutter mechanism (as shown in figure 11), the gear teeth of its carrier wheel 62 are meshed with the 4th driven gear 44 and the 6th driven gear 46 of jack shaft 4, and the location latch 623 of the carrier wheel 62 on first 6 is the draw-in grooves 631 that are fastened in clutch bearing 63 alcoves 630, make carrier wheel 62 hold the location mutually with clutch bearing 63, when input shaft 3 is subjected to the external force rotation, 33 drives of the 3rd driving gear on the input shaft 3 and the 4th driven gear 44 backward rotation of jack shaft 4 of engagement, and the 6th driven gear 46 drives again and the carrier wheel 62 of engagement rotate, 62 clutch bearings 63 that drive engaging mutually of carrier wheel are rotated in the lump, first 6 rotations thereupon, and drive driving gear 64 rotations, 64 drives of described driving gear are located at driven gears 27 in the housing 2 and are and are rotated in the forward, cutter mechanism when the fourth speed position then for just changeing, because of the carrier wheel 62 on first 6 is that the 6th driven gear 46 by the big number of teeth drives, so can increase the rotating speed of cutter, make cutter be fast rotational, the wheel of its farm machinery then relies on the rotation of jack shaft 4 to drive carrier wheel 47 rotations, 47 of described carrier wheels drive output shaft 8 just to be changeed, but 8 driven wheel submechanisms of described output shaft just change, and described farm machinery is advanced.
So, the 6th driven gear 46 that relies on the 4th driven gear 44 and 45 of the 5th driven gears at jack shaft 4 to install a big number of teeth additional, when making carrier wheel 62 move to the fourth speed position, be meshed with the 6th driven gear 46 with the 4th driven gear 44 of jack shaft 4, rely on the 6th driven gear 46 of the described big number of teeth to drive, the rotational speed of cutter is increased, and cutter also is and is rotated in the forward start, can significantly increase the rotating speed of cutter, when cutter will rotate start at a slow speed, only must be with gear switch to the first grade, cutter can rotate at a slow speed, but user's coordinating operation must switch the fast of cutter, low-rotate speed can be more convenient to use for the operator.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within protection scope of the present invention.
