Abstract

PURPOSE:To smoothen the operation to send out the rice plant seedlings to the gate for taking out the seedlings, as being interlocked with the transplantation, without lowering simple seedling supply, by specifying the position of the plane extended from the bottom side of the face on which the seedlings are placed in the seedling stand. CONSTITUTION:The plane T extended from the bottom side of the plate 2a on which rice plant seedlings are placed in the stand 2 is set higher than the projections 23 for conveying them at the start point of the conveying direction in the endlessly rotating belt 8. Thus, a box of seedlings to be transplanted next 15 can be inserted into and slid close to the lower end of the seedling stand 2 so that the former box is pulled up onward without objection.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling transplanter for planting seedlings of crops such as straw grass, and more specifically, to a lower end of a seedling placing surface at a lower side of a seedling placing surface in a tilted seedling placing table. Endless rotation zone with a projection that sends it out toward the seedling take-out port of the section is placed, and the seedling supply box on which the preliminary seedlings are placed and stored is placed on the seedling placement surface and slide-inserted, The present invention relates to a seedling transplanter configured to pull out the seedling supply box to the upper side while opening and swinging the tip side wall member to transfer the preliminary seedling onto the seedling stand.

[0002]

2. Description of the Related Art In the above-mentioned seedling transplanting machine, conventionally, the endless rotary band for feeding seedlings has a tip of a feeding projection protruding above a seedling mounting surface in order to ensure a locking action with respect to seedlings. Generally, the seedling supply boxes are arranged so as to be in the same state or substantially flush with each other, and the seedling supply box is mounted and supported by the stepped portions formed on the respective partition members of the seedling stand.

[0003]

In the above conventional structure, for example, when mat seedlings such as rice seedlings whose roots are relatively thinly intertwined with each other, the locking projections are surely locked to the root portion. It is good to be able to feed vertically, but, for example, when planting a thick rooted seedling, such as a straw seedling, if the structure is such that the locking protrusion protrudes from the seedling placement surface as described above. , There is a possibility that the transfer operation from the placing surface to the vertical feed action part may not be performed smoothly, and in the case of the configuration in which the seedling supply box is pulled out backward, in order to slide and guide the bottom surface, each strip partition member There is a drawback that the structure becomes complicated because it is necessary to perform a special step processing. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic constitution of the present invention, in the seedling transplanting machine described at the beginning, a downward extension surface of a seedling placement surface of the seedling stand is set to a transfer direction start end portion in the endless rotation zone. Is located above the tip of the transfer projection.

[0005]

[Operation] Since the downward extension surface of the seedling placement surface is located above the transfer projection of the endless rotation zone, even if the seedling has a solid root and little entanglement, the endless rotation zone is removed from the seedling placement surface. The transfer to the upper part will be carried out smoothly, and the seedling delivery function will be smooth. Moreover, when supplying the preliminary seedlings, even if the seedling supply box is slid and inserted along the seedling placement surface, the bottom surface does not interfere with the feeding locking projections at the slide tip side,
Further, even if the seedling receiving front end side vertical wall portion is pulled out in a lying state, there is a gap between the seedling placing surface and the protrusions, so that the pulling operation is not hindered.

[0006]

[Effects of the Invention] Therefore, it is not necessary to perform special processing on the seedling stand, and the supply box for the spare seedlings can be inserted and slid up to near the lower end side of the seedling stand, which facilitates the supply work. Moreover, the operation of sending out the seedlings to the side of the take-out port due to the planting operation can be smoothly performed.

Embodiments will be described below with reference to the drawings. Figure 6
Shows a transplanter for straw seedlings. This seedling transplanter is connected to a rear portion of a traveling machine body (not shown) so as to be able to move up and down through a link mechanism, and is horizontally reciprocally moved while the seedlings are placed at a constant pitch with respect to the framed planting transmission case 1. , Each seedling is taken out from a seedling stand 2 provided in a rearwardly inclined posture, and a seedling take-out port 4 formed in a slide rail 3 slidably supporting the lower end of the seedling stand 2 to be planted in a field Before planting operation of the planting mechanism 5 and the planting mechanism 5, the seedlings to be planted are invaded and acted, and the seedlings are pushed toward the seedling take-out port 4, and the seedling holder 6 that holds the state is placed on the mud surface. It is configured with a grounding float 7 that slides. An endless rotary belt type vertical feed device 8 with a protrusion is provided at a position below the seedling placing surface 2a of the seedling placing table 2, and at the end of the lateral movement stroke, the set seedlings are taken out by a predetermined amount. It is configured to send out toward 4. The seedling holder operates in synchronism with the planting operation of the planting mechanism 5, and the holding claws 11 penetrate into the seedlings to hold the seedlings before the seedling removing operation of the planting mechanism 5, and after the seedling removing operation is completed. , Is configured to swing in the retracted posture.

The seedling placing table 2 is provided with a seedling pushing device 12 for pushing each seedling from the rear side of the placed seedling toward the seedling taking-out port 4. The seedling pushing tool 12 is provided in a plate shape, is slidably supported by a supporting rod 14 extending in a cantilever manner from a supporting frame 13 standing at the lower end of the seedling placing table 2, and is slid downward by its own weight. It is configured to move.

When supplying seedlings to the seedling stand 2,
As shown in FIG. 1, the seedling supply box 15 on which the preliminary seedlings are placed is slid and inserted along the seedling placing surface 2a of the seedling placing table 2, and the vertical wall portion (front wall) 15a on the tip side is opened forward. After the rocking, the placed seedlings are transferred onto the seedling stand 2 and the seedling supply box 15 is pulled out rearward. In detail,
The seedling supply box 15 is configured in a box shape with an open upper part, and a preliminary strawberries seedling is loaded and stored in a vertical posture in advance. The front wall 15a is swingably openable about the horizontal axis via the hinge 16 at the lower end, and the front wall 15a can be opened and closed from the rear side. That is, as shown in FIGS. 2 to 5, a support member 17 formed by bending a plate material is attached to one lateral side of the seedling supply box 15, and a side surface of the support member 17 is burred to form a fulcrum portion 18. An operating tool 19 in which a steel wire is bent is rotatably supported on the fulcrum portion 18. Then, the lower end portion of the operation tool 19 is bent laterally, and both side portions of the push-pull rod 20 made of a straight steel wire rod are bent in an arc shape at the bent portion to rotatably interlock and push. The other end of the pull rod 20 is interlockingly connected with a swing operation tool 21 in which the other end of the pulling rod 20 is interlockingly connected to the front wall 15a. The support member 17 is formed with a locking portion 22 that locks and holds the operating tool 19 in a state in which the front wall 15a is maintained in a vertical posture and in a posture in which the front wall 15a is opened and swung.

The downward extension surface T of the seedling placement surface 2a of the seedling placing table 2 is located above the tip of the transfer projection 23 at the starting end in the transfer direction of the vertical feeder 8. Further, the lower end of the seedling placement surface 2a is formed in an inclined posture so that the seedlings can be transferred smoothly. According to this structure, the hinge portion of the front wall 15a does not interfere with the feeding projection 23 of the vertical feeding device 8 when the seedling supply box 15 is pulled out during the seedling replenishing work as described above, and the planting At the time of work, even if the seedlings have relatively hard roots such as strawberries, the seedlings can be smoothly transferred from the seedling placement surface 2a onto the transfer vertical feed device 8 with little resistance.

It should be noted that reference numerals are added to the claims for facilitating the comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
