The paddle 70 of 7 shifts the moving gear on the first shaft 6 to the second gear position of the cutter mechanism (as shown in the eighth figure), and the gear of the moving gear 62 and the second transmission of the input shaft 3 The gear is engaged with the second driven gear 42 of the intermediate shaft 4, and the partial width of the clutch gear 61 on the first shaft 6 is still located in the recess 620 of the moving gear 62. The gear teeth of the clutch gear 61 11 200944676 are still The clamping is positioned in the slot 621 of the recess 620. When the input shaft 3 is rotated by an external force, the second transmission gear 32 on the input shaft 3 drives the moving gear 62 on the first shaft 6 that meshes with it to rotate (eg In the sixth figure, the moving gear 62 drives the second driven gear on the intermediate shaft 4 to be reversely rotated, and moves the gear 62 to drive the clutch gear to be engaged with the first shaft. 6 then rotates and drives the transmission gear 64 to rotate, and the transmission gear 64 drives the driven gear 27 disposed in the casing 2 to rotate. The cutter mechanism e is also in the position of the second slot. The wheel of the agricultural vehicle is driven by the force shaft 3 to rotate the first shaft 6 , and the first shaft 6 drives the intermediate shaft 4 to rotate in the reverse direction. The intermediate shaft 4 drives the moving gear 46 to rotate in the reverse direction, and the moving gear 46 drives the output shaft 8 to be reversely rotated. The output shaft 8 can drive the wheel mechanism to reverse, and the agricultural machine operating handle is turned to make the tool In front, the wheel is behind (that is, moving backwards), and the cutter can be used to loosen the soil while the reverse is going. When the second toggle lever 7 is switched to the third clamp position, the position of the steel ball in the casing 2 is disposed in the third insertion groove 73 of the second paving rod 7 and the second toggle lever 7 The pick 7 〇 will move the third gear position of the moving gear ribs on the first shaft 6 (as shown in the ninth figure), and the second gear of the moving gear = 2 and the input shaft 3 The intermediate shaft 4 = the second driven gear 42 is ridiculed, and the clutch gear _ on the _th fine, the concave chamber 620 of the moving gear 62, when the input shaft 3 is rotated by an external force, and the first transmission on the shaft 3 The moving tooth 2 of the lying wheel 32 is rotated by the belt. The moving gear 62 drives the second slave gear 42 of the intermediate shaft 4 to be sprayed, but the clutch gear 61 is no longer in contact with the moving tooth.合合12 200944676 'Therefore the moving gear 62 does not turn _ co-recorded 61 and the _axis 6 rotates the moving gear coffee in the first - defeat "turn, the first axis 6 of the ^ tooth system stops rotating, so the tool mechanism is When the position of the third slot is stopped, the reverse rotation of the wheel of the vehicle is driven to reversely rotate the moving gear 46, and the moving gear 46 drives the output of the movement. The rotation of the shaft 8 by the output shaft 8 drives the wheel mechanism to reverse, so that the agricultural machinery moves backwards without performing the loosening action.

The pick-up 7_--the moving gear is moved to the fourth gear position of the cutter mechanism (as shown in the tenth figure), and the second gear (10) and the second gear of the moving gear 62 The three-transmission gear 33 (four) is combined with the '(four)-corrected clutch _ value from the concave chamber 620 of the moving gear 62. When the input shaft 3 is rotated by the external force, the intermediate shaft 4 is rotated. The first shaft 6 is not due to the clutch gear 61. Re-locked in the recess 620 of the moving gear 62 'When the moving gear 62 is belted _ only will idle on the first shaft 6 'the first shaft 6 will not rotate 'the cutter mechanism will be in the fourth slot position Stopping the operation, the wheel of the agricultural frequency _ is rotated by the rotation of the towel to move the record 46 to rotate. The shifting wheel 46 drives the output shaft 8 to rotate forward. The output shaft 8 can drive the wheel mechanism to rotate forward. The machine is moving forward. When the second toggle lever is changed to the fifth gear, the position of the steel ball 280 in the shell is intended to be positioned within the fifth positioning recess of the second toggle lever 7, and the second binding 7 is The paddle 70 moves the mysterious gear 62 13 200944676 on the first axle 6 to the fifth gear position of the cutter mechanism (as shown in FIG. 11), and the gear gear of the moving gear 62 and the third of the input shaft 3 The transmission gear 33 and the fourth transmission gear 34 are engaged, and the positioning teeth 623 of the moving gear 62 on the first shaft 6 are engaged in the card slot 631 in the recess 63 〇 of the clutch seat 63, so that the moving gear 62 and the moving gear 62 When the input shaft 3 is rotated by an external force, the third transmission gear 33 and the fourth transmission gear 34 on the input shaft 3 drive the reverse movement of the moving gear 62, and the moving gear 62 is moved. Then, the clutch seat 63 that drives the mutual ❹ is rotated together, and the first shaft 6 rotates accordingly, and drives the transmission gear 64 to rotate. The transmission gear 64 drives the driven gear 27 disposed in the casing 2 to be reversed. When the miscellaneous 'knife lining is set at the fifth age, it is reversed'. The wheel of the Chenye machinery is borrowed from the rotating belt of the intermediate shaft 4. The moving gear 46 rotates. The moving gear 46 drives the output shaft 8 to rotate forward. The output shaft 8 can drive the wheel mechanism to rotate forward, so that the agricultural machinery can advance. Thus, by providing five positioning slots, 72, 73, 74, 75 on the second toggle lever 7 to position the shifting gear of the moving gear, the slave of the present invention is more like a box of agricultural machinery. With a variety of shifting switches, the operation of agricultural machinery is more convenient. In view of the above, the present invention has achieved the intended use and efficacy, and is more desirable and practical than the prior art. However, the above embodiments are merely illustrative of the preferred embodiment of the present invention. This embodiment is intended to be limited to the scope of the invention, and any other variations and modifications which are not to be In the scope of patents.
