Fig. 1 is the schematic representation of the utility model grain combine secondary cylinder gearbox;
Fig. 2 is the utility model grain combine secondary cylinder gearbox designs schematic representation;
Fig. 3 is the structural representation of the power input shaft end of the utility model grain combine secondary cylinder gearbox.
Embodiment
As Fig. 1 Fig. 2 and shown in Figure 3, grain combine secondary cylinder gearbox, comprise gear box 1, in casing 1, be rotatablely equipped with power input shaft 21, jack shaft 11, pto 31 and driving gear set, wherein power input shaft 21 stretches out casing 1 respectively with the mutual end vertical and diaxon of power direction that pto 31 is transmitted, and can carry out the arrangements for speed regulation that the height two-speed is adjusted and also be provided with in casing 1.In the present embodiment, arrangements for speed regulation comprise hard-wired input bevel gear 22 on the power input shaft 21, on jack shaft 11, be equipped with and import the drive bevel gear 12 of bevel gear 22 engagements, and also be installed with high gear 13 and low speed gear 14 on the jack shaft 11, on pto 31, be slidingly fitted with double crosslinking sliding gear 32; In casing 1, also be provided with the double crosslinking sliding gear shift fork, the double crosslinking sliding gear shift fork can be stirred double crosslinking sliding gear 32 slips and mesh respectively to realize at a high speed or the adjustment of low speed with high gear 13 or low speed gear 14 under declutch shift shaft 41 controls, and on casing 1, can be provided with the Joystick 4 of control declutch shift shaft 41, thereby control declutch shift shaft 41 control double crosslinking sliding gear shift forks by Joystick 4 and stir double crosslinking sliding gear 32, and can on declutch shift shaft 41 and casing 1, be provided with the gear locking device as adopting the lock mode of spring ball.
As shown in Figures 2 and 3, can adopt power input shaft 21 vertical mutually with jack shaft 11, and pto 31 carries out the break-in of transmission of power with the mode that jack shaft 11 is parallel to each other, certainly also can adopt power input shaft 21 and jack shaft 11 to be parallel to each other, and pto 31 carry out the break-in of transmission of power with jack shaft 11 orthogonal modes.
As Fig. 1, Fig. 2 and shown in Figure 3, power input shaft 21 stretches out casing 1 end and is provided with power input pulley 2, and pto 31 stretches out casing 1 end and is provided with power-take-off pulley 3.Power is through power input pulley 2 and power input shaft 21 inputs, after intermeshing input bevel gear 22 and drive bevel gear 12 break-ins, pass to jack shaft 11, jack shaft 11 is passed to pto 31 with cooperating of double crosslinking sliding gear 32 with power by high gear 13 or low speed gear 14, outputs power by power-take-off pulley 3 again.
When low speed gear 14 meshes with double crosslinking sliding gear 32, low speed output for big speed ratio, when high gear 13 meshes with double crosslinking sliding gear 32, high speed output for close steps, can realize vertical break-in, two-stage speed governing transmission on the combine-harvester so easily, and can the positive lock gear.
