[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical feeder of a transplanter, and more particularly, to a drive unit having a vertical feed drive shaft having a vertical feed operating member and a follower cam operating in conjunction with the vertical feed operating member. And a vertical feed mechanism having a vertical feed drive unit that rotates in conjunction with the drive unit.

[0002]

2. Description of the Related Art Conventionally, in a transplanting machine in which pot seedlings are taken out one by one from a seedling tray having a plurality of pot seedling accommodating parts and planted in a field, a lateral movement mechanism for reciprocating the seedling tray left and right is provided. In addition, there is provided a vertical feeding device for vertically feeding one hitch at the end position of the left and right reciprocating movement of the seedling tray. As described above, the vertical feed device includes a vertical feed drive shaft that is constantly driven in conjunction with the engine during transplantation operation, and a drive unit that has a follower cam that operates in conjunction with the vertical feed operation member of the drive shaft. A longitudinal feed driver mainly composed of a sprocket, a longitudinal feed driven member forming a pair with the driven member, and a transport band mainly composed of a roller chain stretched between the longitudinal feed driven member and the longitudinal feed driven member. And a drive pin protruding from the chain is engaged between seedling pot bottoms of the seedling tray, and the vertical feed drive unit drives the seedling tray vertically by one pitch. I am trying to do it.

[0003]

In the conventional vertical feeder constructed as described above, the vertical feed operating member is fixed to the vertical feed drive shaft, and therefore has the following problems.

That is, the vertical feed operation member is one of the members.
The follower cam is linked so as to rotate by a predetermined angle by rotation, and the vertical feed driver provided on the output side of the drive unit is rotated based on the rotation angle of the follower cam,
Since the transport belt is moved by a moving amount corresponding to the rotation angle of the follower cam and the seedling tray is vertically fed by an amount corresponding to the moving amount, the moving amount of the seedling tray is the vertical feeding operation member. Is determined by the rotation angle of the follower cam by one rotation of.

However, the vertical feed member is fixedly assembled by welding or bolting the vertical feed drive shaft, and the follower cam or a driven cam for interlocking the follower cam is assembled to a seedling stand frame. The relative position between the vertical feed operation member and the follower cam or the driven cam is shifted due to these assembly errors.

That is, the distance between the axis of the vertical feed drive shaft and the position where the vertical feed operating member comes into contact with the follower cam or the driven cam is shifted.

[0007] When the distance deviates, the rotation angle of the follower cam by one rotation of the vertical feed operation member changes, and the vertical feed amount changes.

For this reason, conventionally, the assembling accuracy of the longitudinal feed operating member to the longitudinal feed drive shaft and the assembling accuracy of the follower cam or the driven cam to the seedling stand frame are required. Also, even when there is no error during assembly, when the transmission gears are incorporated in the transmission system from the follower cam to the longitudinal feed driver, the backlash of the gears changes due to wear due to long-term use. When this occurs, the amount of vertical feeding of the seedling tray changes, and stable vertical feeding performance cannot be maintained for a long period of time.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily correct the rotation angle of the follower cam by the vertical feed operation member to compensate for an appropriate vertical feed amount, to improve the assemblability, and to provide a stable vertical feed for a long time. The point is to maintain performance.

[0010]

SUMMARY OF THE INVENTION In order to achieve the object of the present invention, the present invention relates to a vertical feed drive shaft 3 having a vertical feed operation section S.
7, a drive unit 56 having a follower cam 69 that operates in conjunction with the vertical feed operation unit S, and a vertical feed drive mechanism Y including a vertical feed driver 79 that rotates in conjunction with the drive unit 56. The vertical feed operation unit S includes an interlocking unit 53 that is interlocked with the follower cam 69 and the vertical feed drive shaft 3.
7 and the interlocking unit 53 is connected to the vertical feed drive shaft 37.
And an interlocking portion 53 between the interlocking portion 53 and the mounting portion 54.
Further, an adjusting mechanism C for adjusting the radial position with respect to the longitudinal feed drive shaft 37 is provided.

[0011]

When the rotation angle of the follower cam 69 by the vertical feed operation unit S is out of the rotation angle at which the required vertical feed amount can be obtained, the adjustment mechanism C controls the vertical feed operation unit S.
By adjusting the radial position of the drive unit 56 with respect to the longitudinal feed drive shaft 37 in the above, the correction can be easily made.

Therefore, the accuracy of assembling the vertical feed operation unit S to the vertical feed drive shaft 37 and the accuracy of assembling the follower cam 69 or the follower cam for interlocking the follower cam 69 to the seedling stand frame are compared to the conventional example. The follower cam 69 can be corrected even if the rotation angle of the follower cam 69 is deviated due to a change over time due to long-term use, so that a stable longitudinal feed performance can be obtained for a long time. .

Then, by rocking the lock arm 65,
The roller 65a is disengaged from the lock groove 72a and the lock of the follower cam shaft 66 is released, and the swing of the vertical feed arm 64 causes the roller 65a to engage with the engagement hole 69a of the follower cam 69 via the roller 64a.

The vertical feed can be performed for each pitch a.

After the rotation of the vertical feed operating member 54 has advanced and passed the driven cams 62 and 63, the driven cams 62 and 63 return to their original positions by the action of the return springs 90 and 93. When the vertical feed is completed, the next vertical feed is prepared.

The vertical feed amount is determined by the swing angle of the driven cam 62 by the vertical feed operation member 54, and the speed increasing gear 7 by the shifter 76 of the switching gear 77 is used.
By selecting 3, 74, a vertical feed amount corresponding to these speed increasing ratios can be obtained.

That is, when there are a plurality of seedling pots in the seedling tray 15 having a size of, for example, 25 mm square and 30 mm square, one of the speed increasing gears 73 and 74 depends on the size of the seedling pot 15 a. Is selected, a vertical feed amount corresponding to the size of these seedling pots 15a can be obtained.

By means of a, it can be held at a switching position for switching from neutral to a low speed or high speed range.

The relative position between the vertical feed operation portion S and the follower cam 69 or the driven cams 62 and 63 is shifted due to an assembling error, or the rotation of the follower cam 69 is changed over time due to long-term use. If the angle is deviated and the rotation angle of the follower cam 69 by the vertical feed operation unit S is deviated from the rotation angle at which a required vertical feed amount is obtained, the adjustment mechanism C causes the vertical feed operation unit S to rotate.
By adjusting the radial position of the interlocking portion 56 with respect to the longitudinal feed drive shaft 37 in the above, the correction can be easily made.

That is, the rotation angle of the follower cam 69 by the roller 53d of the vertical feed operation unit S is too small with respect to the rotation angle at which the required vertical feed amount can be obtained, and the drive unit 56 and the vertical feed driving body 79 are not driven. When the vertical feed amount of the seedling pot 15a through which the intermediate bolt 15a is short is insufficient, the tightening bolt 5 of the adjusting mechanism C is used.
4b, the support 53a is moved in a direction away from the longitudinal feed drive shaft 37 by using the long hole 54a of each bracket 54, and the radial distance of the roller 53c from the longitudinal feed drive shaft 37 is reduced. Is adjusted so that the roller 53d becomes longer.
, The rotation angle of the follower cam 69 can be corrected to a predetermined rotation angle at which the required vertical feed amount can be obtained, and the rotation angle of the follower cam 69 by the roller 53d of the vertical feed operation unit S can obtain the required vertical feed amount. If the rotation angle is too large and the amount of vertical feeding of the seedling pot 15a via the driving unit 56 and the vertical feeding driving body 79 is too large, the tightening bolt 54b of the adjustment mechanism C is loosened to The support 53a is moved so as to approach the vertical feed drive shaft 37 by using the long hole 54a of each bracket 54, and is mounted so that the radial distance of the roller 53d from the vertical feed drive shaft 37 is reduced. The position is adjusted, whereby the rotation angle of the follower cam 69 by the roller 53d can be corrected to a predetermined rotation angle at which a required vertical feed amount can be obtained. Therefore, assembling accuracy of the vertical feed operation unit S to the vertical feed drive shaft 37 and mounting accuracy of the follower cam 69 or the follower cam for interlocking the follower cam 6 to the seedling stand frame are much smaller than those of the conventional example. Since the assembling property can be improved accordingly, and the rotation angle of the follower cam 69 can be corrected even if the rotation angle of the follower cam 69 is deviated due to a long-term use, a stable longitudinal feed performance can be obtained for a long time.

In the above-described embodiment, a vertical feed drive unit 98 is formed as the drive case 55 by incorporating the drive unit 56 therein, and this drive unit 48 is attached to the seedling stand frame 14 by the drive case 55. The drive portion 56 can be easily attached to the seedling stand frame 14 because the attachment flange portion 55a is detachably attached via the attachment flange portion 55a, and the assembling property can be improved.

The output shaft 75 is not attached to the seedling stand frame 14 individually, but is attached to the drive case 55. In other words, the output shaft 75 is attached to the drive case 55 before being attached to the seedling stand frame 14. , 66,
The assembly error of the follower cam shaft 66 can be reduced.
Even if a gear speed increasing mechanism composed of transmission gears 70 and 71 and speed increasing gears 73 and 74 is configured between the motor and the output shaft 75, the assembling accuracy can be improved, and the vertical feeding timing and the vertical The feed amount can be adjusted properly, and the drive case 5
5 can be sealed, so that dust and the like can be prevented from entering the drive unit 56. In addition, even when maintenance is performed, the drive unit 56 can be removed from the seedling stand frame 14, so that maintenance can be easily performed. .
