When in use, please refer to the third to _h two figure, when the second toggle lever 7 is switched to the first gear position, the position of the steel ball 28 in the casing 2 is embedded in the second toggle 彳 positioning Positioned in the money 71, and the paddle 70 of the second toggle lever 7 moves the moving gear 62 on the first shaft 6 to the position of the first floor of the control tool mechanism (not shown) (as shown in the seventh figure). The gear teeth of the moving gear 62 mesh with the first driven gear 41 and the second driven gear 42 of the intermediate shaft 4, and the clutch gear 61 on the first shaft 6 is located in the recess 620 of the moving gear 62. The teeth of the clutch gear 61 are locked in the slot 621 in the recess 620. When the input shaft 3 is rotated by an external force, the first transmission gear 31 and the second transmission gear 32 on the input shaft 3 are The fourth transmission gear 34 and the fifth transmission gear 35 drive the second driven gear 42, the third driven gear 43, the fourth driven gear 44 and the fifth driven gear 45 on the intermediate shaft 4 meshed therewith. The intermediate shaft 4 is then rotated, and is coupled to the first shaft 6 of the intermediate driven shaft 41 and the second driven gear. The moving gear 62 is also driven to rotate, and the moving gear 62 is driven to rotate the clutch gear 61 that engages with it. The first shaft 6 rotates with it, and drives the transmission wheel 64 to rotate. The transmission gear 64 is driven to the casing. The driven gear 27 rotates in 2, and the driven gear 27 can drive the relevant mechanism of the tool to move. When the tool j is in the position of the first gear, it is a forward rotation, and the wheel of the agricultural machinery is hunting = medium _ 4 of the __ chick rotation, the moving gear is π move and the first gear 81 on the output shaft 8 is rotated (as shown in the tenth - figure) 'the first gear 81 rotates, its output The rotation of the shaft 8 with the output shaft 8 can then drive the wheel mechanism to rotate forward, so that the agricultural machinery can advance, and the rotation of the wheel moves the moving gear 46 of the middle by 4 by the shift of the first-to-turn 5 The moving gear 46 is operated at a low speed in conjunction with the output shaft 炚-gear 81 (4), and when the moving gear is towed to between the first gear 81 and the second gear 82 of the output shaft 8 (as shown in the thirteenth figure) ), the output shaft 8 is not driven, the wheel mechanism will not operate, when the moving gear 46 moves to and 82_ timely second gear (e.g., FIG households Fourteenth: No), the wheels which were at high speed. When the second toggle lever 7 is switched to the second gear position, the position of the steel ball 2_ is embedded in the second positioning embedded front of the second toggle lever 7, and the second toggle lever 7 is positioned. The paddle 7〇 will be moved to the second target position of the tool mechanism (as shown in the eighth figure: moving: fine: the tactile and the intermediate shaft 4 moving gear 42 are combined) and the first to correct the clutch gear The 戸 见 仍 仍 仍 仍 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The second transfer wheel 32 on the third side drives the moving gear 62 on the first shaft 6 to rotate (as shown in the sixth figure), and the shift-rear wheel 62 drives the intermediate shaft 4 which is merging with it. The second driven gear 42' is in the opposite side of the Hess 62 and is mechanically engaged with the clutch gear to rotate the first shaft 6 to rotate accordingly and drive the transmission gear 64 to rotate. The transmission gear 64 is driven to In the clock 2, the recording machine is turned, the tool mechanism is also rotated in the position of the second tan, and the wheel of the agricultural machine is rotated by the first axis 6 of the input shaft V, first 6 further drives the intermediate shaft 4 to rotate in the reverse direction, and the intermediate shaft 4 drives the moving child wheel 46 to rotate in the opposite direction. The moving tooth=46 drives the output shaft 8 which is incompatible with it to rotate in the opposite direction, and the output force can drive the power. The sub-mechanism is reversed, and the operating handle of the agricultural machine is turned so that the tool is in front and the wheel is behind (that is, it is retreating), and the tool can be used for loosening while the counter is being reversed. When the second toggle lever 7 is switched to the first When the third position is set, the position φ position of the steel ball 280 in the (4) 2 is embedded in the third positioning recess 73 of the second toggle lever 7 and the pick 7 of the second contact lever 7 is the first axis. The moving gear 62 on the 6 is moved to the third gear position of the cutter mechanism (as shown in the ninth figure), and the gear teeth of the moving tooth=62 are still the same as the second transmission tooth and the intermediate shaft of the manual shaft 3 - The driven gear 42 is in phase, and the clutch gear 61 on the first shaft 6 is disengaged from the concave fiber of the moving wire 62. When the manual shaft 3 is rotated by an external force, it is salivated with the second transmission gear 32 on the input shaft 3. The moving gear seems to be driven to rotate, and the moving gear curry drives the private _4 of the second driven wheel 42 to rotate 'but because of the clutch The gear 61 is no longer engaged with the moving gear 62 12 1332555, so the moving gear 62 does not rotate with the #合# wheel 61 and the first shaft 6, and the moving gear 62 forms a turn on the -_, the first The transmission gear 64 stops rotating, so the cutter mechanism is in the stop state in the position of the third gear, and the wheel of the occupational service machine rotates in the reverse direction of the middle_4 to drive the reverse rotation of the moving gear 46. The gear 46 Then, the output shaft 8 engaged with the reverse shaft 8 is reversely rotated, and the output shaft 8 drives the wheel mechanism to reverse, so that the agricultural machinery moves backwards without going through the earth movement. • When the second toggle lever 7 is switched to the fourth gear position, The shell turning position of the steel ball 280 is located in the fourth positioning position 74 of the second toggle lever 7, and the picking piece of the second toggle lever 7 moves the moving gear 62 on the first shaft 6 to the cutter. The fourth position of the mechanism (as shown in FIG. 10), the gear teeth of the moving gear 62 are in harmony with the second transmission gear 32 and the third transmission gear 33 of the input shaft 3, and the first shaft 6 is The clutch gear 61 is disengaged from the recessed gear 620 of the moving gear 62, and the intermediate shaft is driven when the input shaft 3 is rotated by an external force* Rotating, the first shaft 6 is because the clutch gear 61 is no longer held in the recess 620 of the moving gear, and when the moving gear 62 is driven, only the first shaft 6 is turned on the first shaft 6 and It does not rotate, and the cutter mechanism stops in the fourth slot position. The wheel of the mechanical machine drives the shifting wheel 46 to rotate by the rotation of the intermediate shaft 4, and the shifting wheel 46 drives the output shaft 8 to rotate forward. The output is simple and the machine is swaying, so that the agricultural machinery can be broken. When the second toggle lever 7 is switched to the fifth touch, the position of the steel ball 2_ in the shell age is embedded in the second yoke? The fifth fixed slot is positioned internally, and the second shifting lever 7 70 moves the moving gear 62 13 on the first shaft 6 to the fifth position of the cutter mechanism (as shown in the tenth-figure) The age of the moving gear 62 is reduced with the third two-part 33 of the manual shaft 3 and the fourth transmission gear 34, and the positioning teeth 623 of the moving wire 62 on the material-axis 6 are hooked on the clutch seat 63. The card slot 631 in the room coffee enables the mobile = wheel 62 and the clutch seat card to hold the grain, when the manpower ship is rotated by the external force ^ 'the third touch record 33 on the input shaft 3 and the fourth drive record 34 are driven The hobby crane recorded 62 reverse lying, the mobile recording _ led the mutual engagement of the clutch ship-ship rotation, and the belt = transmission gear 64 rotation, the transmission gear _ led the driven gear 27 in the reverse When the tool is rotated, the tool mechanism is reversed when it is placed at the fifth age. The wheel of the agricultural machine drives the moving gear 46 to rotate by the rotation of the intermediate shaft 4. The moving gear 46 drives the output shaft 8 to rotate forward, and the output shaft 8 It can drive the wheel mechanism to rotate forward, so that the agricultural machinery can advance.
