In other words, when scraping the seedlings of one plant with the planting claws (29), the stems and leaves are not damaged and the occurrence of lack of plants can be prevented.

[0010] As described above, in order for the foliage on the seedling mat to assume an upwardly inclined posture, the seedling is grown, for example, as shown in FIG. That is, the seedling mat (40) is arranged at an angle, and the light source (38) is applied from above.
Then, the foliage on the seedling mat grows inclining toward the light source (38), and when wound, the foliage does not break because the seedling is previously inclined. Further, it is not necessary to separately provide a device or the like for setting the stems and leaves in an upwardly inclined posture on the seedling mounting table (20), and a desired seedling mat can be obtained with a simple configuration, so that the cost can be reduced. It is needless to say that a similar result can be obtained even when the seedling mat is arranged horizontally and the light source is irradiated obliquely from above.

Next, such a rolled seedling mat (4)
The seedling table (20) configured to support the above (0) will be further described. FIG. 2 is a schematic side view of the seedling mounting table, and FIG.
Is a schematic front view, and FIG. 4 is a schematic perspective view of a roll-shaped seedling mat. As shown in FIG. 2 to FIG. 4, a roll-shaped seedling mat (40) is mounted on a shaft support member (44) provided on a seedling mounting table (20). Support roll (4) for supporting the
The support roll (41) is provided with a substantially cylindrical roll support shaft (42) projecting from the center of both left and right side surfaces of the support roll (41). Then, the roll support shaft (42) of the roll-shaped seedling mat (40) is locked to the locking portion (45) of the shaft support member (44) of the seedling mounting table (20), and the roll-shaped seedling mat (40) is locked. ) Is arranged so as to contact the vertical transport belt (25) of the vertical transport device (22), and the roll-shaped seedling mat (40) is set on the seedling mounting table (20) so as to be able to be fed out. Planting work is performed.

As described above, the vertical ribs (21) are disposed at predetermined intervals on the upper surface of the seedling mounting table (20), and the shaft support member (44) is located near each vertical rib (21), and 2 per article
They are arranged as one set facing each other. The pair of shaft support members (44) are fixed to the inner surface of the upper end portion on the side opposite to the locking portion (45) by welding the side surfaces of both ends of a substantially U-shaped connection member (48) in front view. The upper surfaces of both ends of the fitting member (49) are fixed to the lower surface of both ends of the connecting member (48) and the upper end of the shaft support member (44) by welding. The insertion member (49) is attached to a bracket (50) attached to the vertical ribs (21) at the left and right ends of the seedling mounting table (20).
7) is formed in a substantially U-shape when viewed from the side so that it can be fitted into the upper part of 7), and a shaft support member (44) and a connecting member (48) formed into a substantially U-shape when viewed from the side are Support shaft (4
7) so as to be rotatable integrally around the center.

According to such a configuration, first, the roll-shaped seedling mat (40) is attached to the shaft support member (44), and then the shaft support member (44) is attached to the support shaft (20) of the seedling mounting table (20). 4
7), the roll-shaped seedling mat (4
0) can be set on the seedling mounting table (20) from above.
The work of setting the roll-shaped seedling mat (40) on the seedling mounting table (20) in the central portion where there is no gap between the rolled seedling mats (20) can be performed easily and conveniently by one person. ) Can be set on the seedling mounting table (20). Further, as shown in FIG. 5, the fitting member (49), one of the left and right shaft support members (44) and the support roll (41) are integrally formed to form the roll-shaped seedling mat (40) into one piece. It may be configured to be held and supported. According to this, the roll-shaped seedling mat (4
The setting of 0) is facilitated, the number of parts is reduced, and the cost can be reduced.

An engaging portion (45) is formed at a lower end portion of the shaft supporting member (44) so that the roll supporting shaft (42) of the supporting roll (41) is rotatably and removably engaged. As shown in FIG. 2, the locking portion (45) is attached to the roll support shaft (4) by the weight of the roll seedling mat (40).
A notch (46), which is cut out in a substantially semi-circular shape toward the outer side of the tip side with which the contact 2) comes into contact, is formed, and the roll support shaft (4) is formed.

4) can be fitted and held in the groove (43). Therefore, the movement of the roll-shaped seedling mat (40) in the vertical and horizontal directions is suppressed, thereby preventing the roll-shaped seedling mat (40) from rotating and vibrating itself and the loosening caused by the vibration of the riding rice transplanter. Therefore, it is possible to prevent the seedling mat from being fed poorly due to loosening.

A weight (not shown) may be provided on the connecting member (48) to further prevent feeding failure. That is, when the roll-shaped seedling mat (40) is set so as to be able to be fed out to the seedling mounting table (20), and the lower part thereof is arranged to be in contact with the vertical transport belt (25), the roll-shaped seedling mat (40) When the number of windings is large, the pressing force on the vertical transport belt (25) is large, but when the number of windings of the roll-shaped seedling mat (40) gradually decreases due to the seedling planting operation, the pressing force decreases. However, there is a possibility that a feeding failure occurs. Therefore, roll-shaped seedling mat (40)
Even if the number of windings is reduced, the vertical transport belt (25) is always
The connection member (48) is provided with a weight set so that the rotational moment on the support shaft (47) is substantially equal between the maximum and minimum winding times so that the pressing force can be secured. According to this, regardless of the diameter of the roll-shaped seedling mat (40), stable feeding performance can be realized, and the planting accuracy can be further improved.

The projections (25) of the vertical transport belt (25)
If a) is formed higher than before, more stable feeding performance can be realized. That is, a roll-shaped seedling mat (40)
Is a nonwoven paper (reinforcing material) at the base of the foliage, and the root is underneath. Especially at high speeds, the conventional projection height results in sending only the root, and the vertical feed amount However, if the protrusion (25a) is formed at a height such that it abuts against the nonwoven paper, the nonwoven paper has a small deflection unlike the root, so that the vertical transport belt (25) It is easy to transmit the driving force directly to the seedling, and stable vertical feeding performance can be realized. When the roll-shaped seedling mat (40) is set in the vertical transport device (22), the seedling mat holder (51) and the cylindrical member (52) which hold the lower part of the seedling mat to prevent the whole from floating are shown in FIG. Since the posture can be changed by rotating the bracket (53) to the non-operation position as shown by the phantom line 2, there is no problem.

In the seedling mounting table (20) as described above, a drug supply device (60) is provided for each row below the seedling mat in the vertical transport direction. As shown in FIGS. 2 and 3, the drug supply device (60) is formed in a funnel shape, and has a rectangular drug inlet (61) which is long at the upper end in the width direction of the seedling table (20).
The lower end is provided with a rectangular medicine outlet (62) elongated in the width direction of the seedling mounting table (20). Then, the discharge port (6) is set near the position where the foliage on the seedling mat is in the upright posture.
For example, a bracket (54) attached to a rib (21) supports a support shaft of a rotating member (63), which will be described later, and is attached to both sides of a rear end portion of an insertion port (61) so that 2) is located. The support rod (59) is fixed by being supported by the support shaft (47).

A large number of holes (6) are provided inside the discharge port (62).
A cylindrical rotating member (63) provided with 3a) is provided to regulate the amount of medicine discharged from the discharge port (62). That is, this rotating member (6
While rotating 3), the medicine leaks from the hole (63a) and drops from the discharge port (62) onto the seedling. The rotating member (63) is driven to rotate via a gear or a belt from a drive shaft (23) or a driven shaft (24) of the vertical transport device (22), or a seedling mat is wound as shown in the drawing. The roller (55) fixed to one (or both) of the roll spindles (42) of the supporting roll (41) and the roller (5) fixed to the rotating member (63).
6) and a belt (57), and a roll support shaft (42).
It is preferable to be configured to be rotationally driven by the rotation of.

As described above, when the driving force of the rotating member (63) is obtained from the vertical transport device (22) or the roll support shaft (42),
Since the supply of the drug and the feeding of the seedlings can be reliably linked, the bending and damage of the seedlings can be reduced, and a smooth planting operation can be realized. When the planting operation is stopped, especially when taken from the roll support shaft (42), the driving of the rotating member (63) is also stopped. Therefore, it is necessary to separately provide a mechanism such as a clutch for stopping the rotating member (63). Cost reduction. In any case, if the drug supply device (60) is disposed in such a position, the drug can be supplied immediately before planting the seedlings, so that the medicinal effect becomes good and You will not be harmed.

[0020]

As described above, according to the present invention, in a seedling mounting table of a rice transplanter configured to be able to support a seedling mat wound in a roll shape, a drug supply device is arranged on the lower side in the vertical transport direction of the seedling mat. Since the outlet of the drug of the drug supply device is provided near the foliage on the seedling mat in the upright posture,
The medicine can be supplied immediately before planting the seedlings, thereby improving the medicinal effect and preventing the seedlings from being harmed. And, since the driving force of the drug supply device is configured to be taken from the vertical conveying device or the axis around which the seedling mat is wound, the supply of the drug and the feeding of the seedling can be reliably linked, and the bending of the seedling can be performed. And damage can be reduced, and a smooth planting operation can be realized. In particular, when the seedling mat is configured to be driven by the rotation of the wound shaft, when the planting operation is stopped, the driving of the drug supply device is also stopped, so that it is not necessary to provide a separate mechanism such as a clutch, thereby reducing costs. I can do it.
