[Detailed description of the invention]

[0001]

The present invention relates to a sliding rail having a frame portion and a vertical portion for receiving seedlings integrally extending from the frame portion so as to slidably receive the lower end portion of the seedling rest. The sliding rail is formed with a seedling take-out port through which a planting claw passes, and a take-out port guide is attached along an edge of the seedling take-out port, and the planting is provided below the seedling take-out port. The present invention relates to a seedling planting device provided with a seedling guide for preventing the seedlings from being taken out and spread along a movement path of a nail.

[0002]

2. Description of the Related Art In recent years, in such a seedling planting apparatus as described above, seedlings are cut one by one from mat-shaped seedlings placed on the seedling rest at the lower end of the seedling rest and planted in a field. As a mechanism, a rotary-type mechanism has been adopted in which a rotating case having a pair of planting claws is driven to rotate to increase the seedling planting speed. Therefore, some users, such as farmers, own seedling planting equipment that employs the rotary planting mechanism,
Some plants own a seedling planting device that employs a rocking type planting mechanism that drives a rocking arm with a single planting claw before speeding up. Regarding seedlings, instead of growing mat-shaped seedlings suitable for the seedling planting equipment owned by them, purchase seedlings that have been intensively and uniformly raised with an emphasis on productivity at the nursery center. ing.

[0003] Therefore, if the purchased mat-like seedlings are planted by a seedling planting apparatus employing a rotary type planting mechanism, the mat-like seedlings cannot withstand high-speed planting from the viewpoint of productivity. The seedlings cut by the planting claw of the planting mechanism are easily broken by the impact of cutting from the mat-shaped seedlings by not being bred to have enough strength, and the planting speed has been increased. With the increase in the centrifugal force applied to the cut seedlings, the inconvenience that the cut seedlings are separated and detached from the planting claws is likely to occur until the seedlings are planted in the field. I have.

Therefore, in order to prevent the above inconvenience,
In a seedling planting apparatus employing a rotary planting mechanism, the length of the seedling guide extending downward from the seedling outlet of the sliding rail along the movement locus of the planting claw is made as long as possible. However, if the seedling guide is lengthened, the moment applied to the connection between the seedling guide and the sliding rail, which is the supporting portion of the seedling guide, tends to increase when the planting claw passes. Therefore, it is necessary to increase the strength of that part.

[0005] In a seedling planting apparatus employing a rotary planting mechanism, the shear force at the time of cutting a seedling with a planting claw is increased, so that a takeout guide which is a support portion of the takeout guide is provided. Since the moment applied to the connecting portion between the rail and the sliding rail tends to increase, it is necessary to increase the strength of that portion. The outlet guide is for preventing the sliding rail from being deformed and damaged due to the shearing force when cutting the seedling with the planting claw.

From these points, conventionally, in the seedling planting apparatus as described above, for example, as shown in FIG. 8, the take-out port guide 15 is connected to the vertical surface portion of the sliding rail 14 and the seedling mounting surface. It has been conceived to increase the supporting strength of the outlet guide by connecting the bolts to the slide rails at each of the outlet forming portions connected to the outlet. On the other hand, although not shown, the seedling guide is bolted to the sliding rail at each of the vertical surface of the sliding rail and the outlet forming portion connected to the seedling mounting surface, similarly to the outlet guide. In order to increase the support strength of the seedling guide, by connecting, or, in each of the vertical surface portion equivalent portion and the extraction port forming portion equivalent portion in the extraction port guide, by bolting to the extraction port guide. Was thought to be.

[0007]

However, in the above-mentioned conventional structure, the bolt forming operation is difficult to perform because the take-out opening forming portion is located inside the back side of the wide seedling rest. As a result, there is a disadvantage that the assembling workability is deteriorated. An object of the present invention is to improve assembling workability without reducing durability.

[0008]

The present invention is characterized in that a lower end portion of a seedling rest is slid by a sliding rail having a frame portion and a vertical portion for receiving a seedling extending integrally from the frame portion. It is configured to be movably received, and a seedling take-out port through which a planting claw passes is formed on the sliding rail, and a take-out port guide is attached along an edge of the seedling take-out port, and a portion below the seedling take-out port is provided. In a seedling planting device provided on its side with a seedling guide for preventing the spread of picked-out seedlings along the movement trajectory of the planting claw, the pick-out port guide and the seedling guide are fastened together to the receiving vertical surface portion. While being connected, one end side of the outlet guide is received and supported by the frame portion, and the frame portion is prevented from moving along the seedling removal direction of the outlet guide. That lies in is formed a locking portion.

[0009]

[Function] Since the take-out guide and the seedling guide are jointly connected to the receiving vertical surface located at a position facing the lower outside of the seedling rest, there is no need to insert a hand deep inside. Bolts can be easily tightened. In addition, even if the vertical surface of the sliding rail is bent downwardly in accordance with the seedling removal operation of the planting nail, it is received by the highly rigid frame portion formed in a square pipe shape through the extraction port guide. Supported. In addition, a force is applied downwardly to the extraction port guide at the inner side of the seedling extraction port along with the seedling extraction operation, but movement in the seedling extraction direction is prevented by the locking portion formed on the frame portion. , Deformation and the like can be effectively prevented.

[0010]

[Effects of the Invention] Accordingly, it is possible to effectively receive and support the external force caused by the action of the planting nail to take out the seedling, and to improve the durability so that deformation and damage at the portion where the seedling is taken out can be prevented. However, the assembly workability was excellent.
