Generally, the speed of agricultural farming is generally not high. Therefore, the movement or movement of the agricultural machinery is not too fast. The household is required to set the speed between the output power source and the output device. The gearbox, which allows the high-speed motor output to utilize the gear ratio adjustment ratio to a lower speed output to match the needs of the farming operation. For example, Taiwan Patent Publication No. 338226 "Agricultural Machinery Gear Transmission Box (4)" new patent case, its structure, please refer to the seventh and eighth figures, the first linkage shaft (60) is a power transmission structure, which can drive the motor The power adjusted by the shift gear set is transmitted to the first wheel shaft (70)' through the meshing with the output gear (71) to drive the wheel provided on the first output shaft (7〇) to drive the agricultural machinery forward. The first output shaft (70) may be composed of a shaft core portion (72) and two output rods (73) (74) penetrating the housing (90), wherein the shaft center portion (72) and the output gear (71) In combination, one end of the two output rods (73) (74) can be sleeved on both ends of the shaft portion (72), and the two output 5 M317751 rods (73) m) are directed toward the output gear. (71) - a clamping plate (75) is fixed at the end, wherein a plurality of ring-shaped teeth (π" are arranged on the surface of the clamping plate (75) facing the output gear (7). The wheel rod (73) (74) on the other side of the chucking plate (75) is sleeved with an end of the spring (752) on the housing (9〇), and the output core (71) There are a plurality of card holes (7 inches) which are opposite to the respective teeth ((5)) of the two card trays (75) and are engageable therein.

Thus, when the steering lever (8〇) is rotated, it can be pushed through the steering ring (81). The chucking plate (75) is axially moved along the axial center (Μ), so that when the motor power is transmitted to the output gear (71) via the shifting gear set, the locking hole (711) and the two clamping discs can be used ( 75) The locking relationship of the latching teeth (751) simultaneously drives the two output levers (73) to rotate simultaneously. When the user rotates one of the steering levers (8〇), the steering ring can be driven by the steering ring "" The chucking plate (75) is axially moved along the axial center portion (72) to disengage the engaging teeth (751) of the chucking disc (75) from the output gear 71), thereby allowing the card The second output rod (74) combined with the disc (75) is disengaged from the transmission relationship with the shaft portion (72), and the power transmitted to the f gear (71) at this time is only used by another clamping disc (75). ) * passed to the output talent (73), and will not pass at the same time The second output rod is moved ((4), so that only the wheel disposed on the first output rod (73) is rolled, and the wheel disposed on the second output rod (74) remains undriven to 6

Rotate, Sa to change the operation of the agricultural machinery and move the raft, after the agricultural machinery moves to the special angle, 'the steering rod (9) can be released to push the control wheel (33) back with the spring force of the spring (34) The internal gear of the transmission gear (32) (Μ. Phase card system) allows the power to be output simultaneously from both ends of the output shaft (4〇), so that the agricultural machinery can resume straight travel. When using the steering rod (5〇) to push the top The control wheel (33) causes the gear (33) to be disengaged from the internal gear (321) to deflect the agricultural machine, and the steering mechanism (50) is released for the agricultural machinery to resume straight travel by the spring (34) The elastic force pushes the twisting wheel (33) back into the action of the internal gear (321) of the transmission gear (32). 'Because of the locking relationship between the gear (331) and the internal gear (321), the gear is engaged, so even two The interface will not produce a large impact at different relative speeds. Compared with the existing easy-to-deplete carding method, it is a better and improved creation. [Simple description of the drawing] The first picture is the appearance of some components of the creation. Figure 12 M317751 The second picture is the third component of the creation. Figure 4 is a side view of the creation. The fourth part of the creation is a cross-sectional view of the components. The fifth figure is a part of the components of the creation. The sixth figure is a part of the component of the creation. The third embodiment of the prior art control structure is a partial cross-sectional view of the prior art.
