Moreover, it is good also as a crawler type traveling apparatus.

Next, the seedling transport unit 3 and the seedling planting body 4 will be described.
The seedling planting body 4 is connected to a drive unit 16 that moves the seedling planting action part 4a up and down, and the seedling planting action part 4a of the seedling planting body 4 is a pair of seedling planting clamps (see FIG. 5). Only one of them is shown), which acts on the seedlings transported by the seedling transporting unit 3 to plant the seedlings in the field.

  The drive unit 16 that drives the seedling planting body 4 includes a drive shaft 19 provided in the planting transmission case 18 that includes a transmission mechanism that receives power for driving the seedling planting body 4 from the transmission case 8 and transmits it. Power is transmitted.

  Then, the seedling transport unit 3 drives a rotating body 29 to 32 that rotates an endless belt 26 a of the seedling container 26 from a driving sprocket 20 fixed to a driving shaft 19 provided in the transmission case 18 via a chain 21. Power is transmitted to the sprocket 22.

  Further, the drive unit 16 of the seedling planting body 4 is configured to transmit power from the drive shaft 19 via the universal joint 24, and the point at which the rotation of the universal rod 25 connected by the universal joint 24 is accelerated is the seedling planting body. 4 when the action part 4a is inserted into the field. As a result, the time during which the action part 4a of the seedling planting body 4 is inserted into the field is shortened, the planting hole in the field is reduced, and appropriate seedling can be planted.

The base of the drive unit 16 of the seedling planting body 4 is fixed to the tip of the support arm 40. The support arm 40 is supported by a support arm 39 attached to the steering handle frame 2b so that the fulcrum 40a on the base side can swing freely. Further, an attachment arm 41 is attached to the steering handle frame 2b, and the upper end of the drive unit 16 is supported via a screw shaft 45 on the tip of a rotary handle support member 43 integral with the attachment arm 41. . A rotation handle 42 is attached to the rotation handle support member 43.
Accordingly, the length between the rotary handle support member 43 and the drive unit 16 can be adjusted by rotating the screw shaft 45 that expands and contracts by the operation of the rotary handle 42.

  The seedling planting body 4 is swingably supported by a pair of swing arms 4c and 4c each having a lower end attached to drive shafts 47 and 47 that are arranged in parallel so as to protrude leftward from the drive unit 16. The pair of swing arms 4c, 4c is mounted so as to swing in a direction orthogonal to the longitudinal direction of the drive shafts 47, 47, and the base of the seedling support portion 4b is attached to the tip of the pair of swing arms 4c, 4c. It has been. Further, a central portion of one swing arm 4c of the pair of swing arms 4c (4c in the example shown in FIG. 1) is rotatably supported on the side wall surface of the drive shaft 16. Two foldable arm members 48 and 49 are connected. That is, one end of one of the two arm members 48, 49 is rotatably supported on the side wall surface of the drive shaft 16, and the other end of the arm member 48 is one end of the other arm member 49. The other end of the arm member 49 is rotatably supported by the central portion of the swing arm 4c.

  Accordingly, when the pair of swing arms 4c, 4c swing around the drive shafts 47, 47, the seedling support portion 4b also swings, and the action portion 4a at the tip of the seedling support portion 4b is indicated by a locus T in FIG. Reciprocates on orbit.

  Further, by rotating the rotary handle 42 and changing the distance between the distal end portion of the rotary handle support member 43 and the distal end portion of the drive unit 16 via the screw shaft 45, the drive unit 16 is allowed to swing (support member 40). Swinging in the vertical direction around the base fulcrum 40a), the position of the swinging fulcrum (drive shafts 47, 47) of the swinging arms 4c, 4c is changed, and the locus of the action part 4b of the seedling planting body 4 is changed. T is also changed.

  When the tip of the drive unit 16 moves in the arrow S1 direction, the locus T of the action unit 4b also moves in the arrow S2 direction, and the vine seedling can be planted by a planting method called “oblique planting”. When the tip of the drive unit 16 moves in the direction opposite to the arrow S1, the trajectory T of the action unit 4a also moves in the direction opposite to the arrow S2, and planting the vine seedling more horizontally, called “ship bottom planting”. Can do.

At this time, the locus T of the action part 4a of the seedling planting body 4 passes near the swing fulcrum of the drive part 16 (the fulcrum 40a on the base side of the support member 40), and the action part 4a passes near the fulcrum 40a. At this time, the seedlings of the seedling transport unit 3 can be taken, and this position can be set as the seedling picking position, so that stable seedling planting is possible.
Therefore, the planting posture change of the seedling can be easily adjusted steplessly with a simple configuration according to the kind of the vine seedling or according to the customs of each region.
In addition, the action part 4a of the seedling planting body 4 is composed of a pair of left and right, and the seedling can be gripped at a timing when the pair of action parts 4a pass through the seedling taking position.

An irrigation channel is provided inside the support part 4b of the seedling planting body 4, and water flowing through the channel is discharged from a notch 4b1 provided in the support part 4b near the action part 4a. deep. FIG. 5 shows only one inner side of the pair of seedling planting bodies 4 (the side facing the other seedling planting body 4). Can be irrigated directly. Therefore, not only can the water be directly applied to the seedlings, but also the seedling transplanted body 4 prevents the seedlings from being brought back, so that the seedlings after transplanting are well established and grown.

  FIG. 5B shows a side view of the support portion 4b in the vicinity of the action portion 4a when the hole 4b2 is formed in the support portion 4b of the seedling planting body 4 of another embodiment, and FIG. By providing a hole obliquely with respect to the longitudinal direction of the support part 4b as shown in a longitudinal sectional view of the support part 4b when the hole 4b2 is opened in the part 4b, water is discharged toward the tip of the action part 4a. Can be applied to the root of the seedling.

Thus, by having the structure shown in FIG. 5, the notch part 4b1 for water discharge | emission is obtained only by scraping the front-end | tip of the support part 4b of the seedling planting body 4, and the seedling planting body 4 excellent in workability is obtained. Not only can it be produced, but also the possibility of crushing the water discharge opening during welding connection of the action part 4a can be avoided.
In addition, since the protrusion part 4a1 is provided in one inner side of a pair of seedling planting bodies 4, the hold | gripped seedling can be hold | gripped reliably without slipping.
