Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of a seedling stand for a rice transplanter. This is an improved mounting structure for the floating comb-shaped seedling support rod.

[Prior art]

The comb-shaped seedling support rod, which lifts the bottom surface of the seedlings from the seedling tray sliding rail and prevents the seedlings from sliding against the seedling tray sliding rail, is bolted, screwed, or welded to the bottom of the seedling tray. (for example, Japanese Utility Model Application Publication No. 100824/1983).

[Problem that the invention attempts to solve]

When attaching the comb-shaped seedling support rod to the seedling stand with bolts or screws, it is necessary to process screw taps on the comb-shaped seedling support rod and the bottom of the seedling stand, making the installation process complicated. Moreover, it has the disadvantage that it is troublesome to assemble, and when it is attached by welding, the bottom surface of the seedling stand is distorted due to the influence of heat, which adversely affects the ability of the seedlings to slide down.

Therefore, in order to omit the mounting structure of the comb-shaped seedling support rod, it is conceivable to integrally mold the comb-shaped seedling support rod when forming the seedling stand, but in such a case,
The molding of the formwork was complicated, and the comb-shaped seedling support rods could not be repaired due to wear or damage.

The present invention employs a structure that allows the comb-shaped seedling support rod to be repaired, while also allowing it to be easily attached to a seedling stand.

[Means to solve the problem]

The comb-shaped seedling support rod is engaged and connected to a hole for protruding a vertical seedling feed claw.

[Effect]

According to the above configuration, the comb-shaped seedling support rod projects from the back side of the seedling rack, through the hole for protruding the vertical seedling feeding claw, above the bottom surface of the seedling rack and forward from the front edge of the bottom surface of the seedling rack. By attaching it in this condition, the hole for protruding the vertical seedling feed claw can be used as the engagement structure of the comb-shaped seedling support rod.

[Effect of idea]

Since the hole for protruding the vertical seedling feed claw is used for the engagement structure of the comb-shaped seedling support rod, there is no need to perform processing such as screw taps on the comb-shaped seedling support rod or the bottom of the seedling tray, and there is no need for assembly. In this case, the comb-shaped seedling support rod can be easily installed from the back of the seedling stand without using a screwdriver or spanner by simply inserting the comb-shaped seedling support rod into the hole for protruding the vertical seedling feed claw.

Moreover, since it is configured to be detachable from the seedling stand, there is no possibility that it cannot be repaired if it breaks, unlike when it is integrally molded with the seedling stand.

〔Example〕

The figure shows a seedling tray of a 6-row rice transplanter, in which 1 is a seedling tray on which pine-shaped seedlings W are mounted, and the seedling tray 1 is intermittently moved back and forth in the left and right directions with respect to the lower seedling tray sliding rail 2. Ru. The seedling platform sliding rail 2 includes:
Seedling extraction port 4 for passing through planting claws 3 that operate in vertical circulation
is formed, and is configured to take out one seedling block from the lower end of the pine-shaped seedling W using the planting claws 3 as the seedling stand 1 is moved laterally.

5 is a star wheel-shaped vertical feed pawl that rotates downward by a certain angle when the seedling tray 1 reaches the end of horizontal feed, and vertically feeds the pine-like seedling W downward; The top is the bottom of the seedling stand 1
It is provided so as to protrude from the through hole 6 formed at a.

The seedling rack 1 is provided with a comb-shaped seedling support rod 7 that protrudes downward from the front edge 1b of the bottom surface 1a of the seedling rack, and a comb-shaped seedling support rod 7 that projects downward from the front edge of the bottom surface of the seedling rack 1 is provided. It is configured to receive the pine-shaped seedling portion from below and reduce the relative friction with the seedling tray sliding rail 2 that occurs when the seedling tray is moved laterally.

The comb-shaped seedling support rod 7 is constructed by arranging a plurality of comb-shaped unit parts 7A each having an inverted U-shape in plan view, and each comb-shaped unit part 7A is formed in a W-shape in rear view. Then, insert the holes 6, 6 for the left and right pair of vertical seedling feed claws.
The seedling pedestal is inserted from the back side of the seedling pedestal to support the seedlings, and the seedling pedestal is sandwiched from the front and back by the parts 7a, 7a that support the seedlings, and the part 7b that contacts the back side of the seedling pedestal, and the seedlings are The supporting portions 7a, 7a are attached in such a manner that they are in contact with the side edges 6a, 6a of the holes 6, 6 to prevent lateral movement. Moreover, the comb-shaped seedling support rod 7 is formed of an elastically deformable spring wire material, and when the comb-shaped seedling support rod reaches the seedling take-out port, the comb-shaped seedling support rod 7 is made of a spring wire material that can be elastically deformed. It is configured to be elastically deformable.

[First Alternative Embodiment] As shown in FIG. 4, the tip portions 7a, 7a of the comb-shaped rods that contact the bottom surface of the front row of seedlings to be taken out by the planting claws are slightly bent upward, and the seedlings are placed on the top. It may be configured to prevent relative friction of the comb-shaped rod with respect to the platform sliding rail 2.

[Second Alternative Embodiment] As shown in FIGS. 5 and 6, the comb-shaped unit part 7A of the comb-shaped seedling support rod 7 is configured to be attached to one hole 6 of the vertical seedling feed claw 5, The comb-shaped portion may have a finely spaced mesh to support the pine-shaped seedlings finely and evenly.
