Abstract

PURPOSE:To equalize a load due to a device for removing the backlash operable in passing a planter through a seedling-carrying platform with a load produced in order to lift a push-out tool. CONSTITUTION:This apparatus for planting seedlings is obtained by constituting a pair of planters 13 of downward directing separating pawls 28 and a push-out tool 30 capable of vertically moving under the separating pawls 28 by rotating a cam 26. installing the pair of planters 13 in symmetric positions of a turning case 16 so as to turn while keeping a similar posture by meshing of gears, arranging either of the planters 13 so as to pass through an end of a seedling- carrying platform 12 in a lowering stroke during the turning, scrape off a seedling for one stock so as to push down the seedling by lowering the push-out tool 30 at the lower end thereof, installing a device for removing the backlash capable of bringing the corresponding tooth surface of the gears into contact with a prescribed side in passing through the seedling-carrying platform 12 with the respective planters 13 and forming a cam 26 so as to lift the push-out tool 30 against a spring 31 following the rotation of the cam 26 after passing the other planter 13 through the seedling-carrying platform 12.

2. Description of the Related Art In order to increase the vehicle speed and improve the efficiency of seedling planting work without increasing the turning speed of the planting device (separating claw), a pair of planting devices are provided at symmetrical positions of the swiveling case. A rotary type seedling implanting device that alternately implants seedlings is used. The planting device is composed of a downward separating claw and an extruding tool that moves up and down under the separating claw by rotation of a cam. Then, in the descending stroke during turning, the seedlings for one plant are taken out through the end of the seedling mounting table, the extruding tool descends at the lower end to extrude the seedling into the soil, and then the extruding tool in the ascending stroke. Is rotated against the spring by the rotation of the cam to prepare for taking out the seedlings.

Further, the planting device is connected to a gear (sun gear) fixed to the machine body in order to rotate in the same posture. Therefore, the lower end of the planting device swings back and forth due to the backlash generated between the gears. If this fluctuation occurs when passing through the seedling mounting table, the amount of seedlings taken may be excessive or insufficient, and the number of seedlings planted may be disturbed. In order to prevent this, when the planting device passes through the seedling mounting table, a backlash removing device is provided to bring the tooth surface of the gear into strong contact with a certain side (Japanese Utility Model Laid-Open No. 3-71713, Japanese Patent Laid-Open No. 17713/1993). 61-271907).

That is, a load that causes the backlash removal device to act on one of the planting devices and a load that raises the pusher tool against the spring in the other planting device occur in a duplicated manner, and the load fluctuation is fluctuating. A large load peak occurs locally. Therefore, in the conventional device, there is a possibility that vibration may occur or uneven wear may occur in the transmission path.

As described above, the separating claw 28 is used as the seedling mounting table 12.
In the eccentric body 35 on the side passing through the end of the sun gear 19, the intermediate gear 2 and the intermediate gear 2 are operated by the lever 36 compressing the spring 38 and the backlash removing device 39 operating.
3 and the tooth flanks of the planetary gears 22 are strongly pressed against the surfaces on the fixed side, and the tip of the separation claw 28 is prevented from swinging back and forth to maintain a constant trajectory. At this time, the other separating claw 28 is in the ascending stroke of the extruding tool 30 at the lower end of the swivel trajectory, but the one separating claw 28 has the one separating claw 28.
2, the pawl portion 32a of the lever 32 moves to the cam 2
Climb to the mountain portion 26a of No. 6. Then, the spring 31 is compressed, and its lever 32 is pushed clockwise to rotate the push rod 29.
And, the push-out tool 30 is pulled up to prepare for the next passage of the seedling stand 12. The chain line in FIG. 6 shows the peak portion 26a of the conventional cam 26. According to this conventional device, the claw portion 3 is formed.
Immediately after 2a has fallen into the valley portion 26b, the pushing tool 30 starts to rise. Therefore, this rise and the other separating claw 2
The backlash removing device 39 in 8 operates in duplicate.
