(5) with the rotation of the spiral wheel 530, the swing link 520 is also transformed from the state shown in fig. 7 to the state shown in fig. 6.
The special swather of edible beans of this embodiment passes through the continuous swing of pendulum rod 520 for different plants are emptyd towards different directions, and then make the plant of spreading out on ground intersect each other, and certain stack appears in the first half and the latter half of plant, and the space between upper plant and the lower floor's plant also can increase, is favorable to drying the fruit of concentrating on the first half of plant (for example, the pod of various edible beans).
If the edible bean plants which are not desired to be cut down are arranged crosswise, the user does not need to start the swing link 520, and at this time, the user can rotate the swing link 520 to make the thick rod section of the swing link 520 separate from the first mounting hole with the thread of the first base plate 551, and then insert the swing link 520 into the storage sleeve 511 and screw the same, as shown in fig. 8 in particular; in this state, the thin rod section of the swing link 520 is closest to the spiral wheel 530, and since the swing link 520 becomes thin, the spiral wheel 530 is no longer in contact with the swing link 520 at this time, and friction is not generated with the swing link 520 even if the spiral wheel 530 rotates.
In other non-working occasions, the state that the swing rod 520 extends rightwards causes a lot of troubles; thus, after the windrower is shut down, the user should also screw the swing link 520 into the pocket 511 as shown in FIG. 8.
Although the embodiments of the present invention have been described in the specification, these embodiments are merely provided as a hint, and should not limit the scope of the present invention. Various omissions, substitutions, and changes may be made without departing from the spirit of the invention and are intended to be within the scope of the invention.
