Example 2

Compared with the embodiment 1, the example has the technical characteristics that: the telescoping device 2 can set up to electric telescopic handle, realizes defeated seedling pipe 3's up-and-down motion through electric telescopic handle. The other technical features of this embodiment are completely the same as those of embodiment 1, and are not described herein again.

The working principle is as follows:

after the tree planting machine reaches the designated position, the expansion device 2 receives an execution command of the control system to start working, the water inlet 301 and the air inlet 302 simultaneously work, and the mixed high-pressure water is sprayed out of the seedling conveying pipe 3. When the telescopic device 2 starts to push out and push out, the seedling conveying pipe 3 moves downwards, meanwhile, the friction plate 7 fixed on the seedling conveying pipe 3 moves downwards to drive the meter counting wheel 9 to rotate in the forward direction, the rigid coupling 10 is driven to rotate, at the moment, the inner ring and the outer ring of the one-way bearing 25 are in a locked state, the one-way bearing 25 drives the first rotating shaft 14 to rotate, when the pinion 17 on the first rotating shaft 14 rotates, the gear wheel 19 meshed with the pinion 14 rotates with the gear ratio of 1:4, then the driving drive plate 20 on the second rotating shaft 18 rotates along with the pinion, the driving drive plate drives the driven grooved wheel 22 on the third rotating shaft 21 to rotate, and then the driving crank wheel plate 23 drives the seedling standing groove plate 12 to rotate along the guide seat 13 through the hinge connecting rod mechanism, so that the seedling standing work is completed. In the whole process, the large gear 19 reduces the rotation angle of the small gear 17 by four times and then transmits the rotation to the sheave mechanism, and the rotation is accumulated in the sheave mechanism, so that the large gear 19 rotates exactly for a circle when the seedling conveying pipe 3 descends for proper times. When the action is withdrawed to telescoping device 2, defeated seedling pipe 3 upward movement, friction plate 7 drive meter rice wheel 9 antiport, but the inner and outer lane of one-way bearing 25 is in the unblock state this moment, and meter rice wheel 9 antiport is followed to one-way bearing 25's outer lane, but the inner circle irrotational, so defeated seedling pipe 3 upward movement, first pivot 14 does not follow meter rice wheel 9 and rotates, and the mechanism will not feed the actuating mechanism transmission rotation to the sapling to wash away the pit.

When the telescopic device 2 drives the seedling conveying pipe 3 to repeatedly go up and down to punch the pit, the seedling feeding driving mechanism only rotates in a single direction, so that the seedling feeding driving mechanism is accumulated to rotate, and the purpose of intermittently controlling seedling supply is finally achieved. The seedling conveying pipe 3 is inserted downwards once, the pinion 17 rotates exactly for a circle, the seedling planting pit is flushed after the seedling conveying pipe 3 is inserted downwards for three times, the driving plate 20 in the geneva gear starts to stir the driven geneva wheel 22 to rotate when the seedling conveying pipe is inserted downwards for the fourth time, then the driving crank wheel plate 23 and the transmission plate 24 drive the seedling erecting geneva plate 12 to rotate along the guide seat 13 to erect the seedlings, the seedlings slide into the seedling conveying pipe 3, and therefore the seedling feeding purpose is achieved, and finally the whole mechanical transmission system is restored to the initial state to complete the preparation of next seedling planting.
