The present invention relates to a seedling planting device provided with a seedling guide for preventing the spread of the removed seedlings.

[0002]

[Prior art]

 In the above-mentioned seedling planting apparatus, conventionally, as shown in FIG. 8, for example, the seedling take-out port guide 15 is provided with a vertical surface portion of the slide rail 14 and an take-out port forming portion continuous with the seedling placement surface. In each case, bolts were connected to the sliding rails to prevent deformation and damage due to seedling removal action by the planting claws.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, since the extraction port forming part is located in the inner part on the back side of the wide seedling stand, it is difficult to perform bolt tightening work, resulting in poor assembling workability. There was a flaw. The purpose of the present invention is to improve the workability of assembly without lowering the durability.

[0004]

[Means for Solving the Problems]

 According to a characteristic configuration of the present invention, in the seedling planting apparatus described at the beginning, the extraction guide and the seedling guide are jointly fastened and coupled to the receiving vertical surface portion, and one end side of the extraction guide is connected. In this point, the frame part receives and supports the frame part, and the frame part is provided with a locking part for preventing the pick-up port guide from moving in the seedling taking-out direction.

[0005]

[Action]

 The take-out port guide and the seedling guide are jointly connected to the vertical vertical surface for receiving at the position facing the lower and outer side of the seedling stand, so there is no need to put your hands inward. It will be easier to tighten the bolts. Also, when the seedlings are taken out from the planting claws, the vertical surfaces of the sliding rails are bent and deformed downward, and are formed into a square pipe shape to be received and supported by the frame portion having high rigidity. In addition, a force is applied downward to the pick-up guide at the inner side of the pick-up opening as the seedlings are picked up, but the locking part formed on the frame prevents movement in the seedling pick-up direction. , Deformation, etc. can be effectively prevented.

[0006]

[Effect of device]

 Therefore, the durability can be improved while effectively receiving and supporting the external force that accompanies the action of taking out the seedlings of the planting claws to prevent deformation and damage at the seedling taking-out portion. It has excellent workability.

While the tip of 12 draws an elliptical locus in a side view, the seedlings on the seedling stand 1 are taken out from the seedling take-out port 13 one by one and planted.

The configuration of the seedling take-out section will be described below. As shown in FIGS. 2 and 3, a sliding rail 14 having a square pipe-shaped frame portion 14a and a seedling receiving vertical surface portion 14b integrally extending from the frame portion 14a is used to slide the seedling stand 1 The lower end portion is slidably received, and the slide rail 14 is formed with a seedling take-out port 13 through which the planting claws 12 pass, and the seedling take-out port guide 15 is provided along the edge of the seedling take-out port 13. A seedling guide 16 is provided below the seedling take-out opening 13 along the movement path of the planting claws 12 to prevent the taken-up seedlings from spreading.

The seedling take-out port guide 15 is made of a metal material, and is arranged along the edge of the take-out port 13 as shown in FIGS. 6 and 7, and the shearing force by the cutting action of the seedlings by the planting claw 12 is applied. The sliding rail 14 is prevented from being damaged due to the above. To be more specific, the seedling take-out port guide 15 is provided with a vertical plate-shaped opening forming portion 17 formed in a U-shape in a plan view along the edge of the taking-out port 13, and extended on both left and right sides of the opening forming portion 17. It is composed of a plate-shaped mounting portion 18 having an L-shape in a side view and arranged along the lower side of the outlet forming portion of the sliding rail 14, and the mounting portions 18 are provided at two locations on each of the left and right sides of the opening forming portion 17. The sliding rail 14 is configured to be bolted and fixed to the seedling receiving vertical surface portion 14b. Further, the inner side surface 17a of the opening forming portion 17 is brought into contact with and supported by one side surface of the frame portion 14a of the sliding rail 14 so as to receive and support the load when the seedlings are taken out by the planting claws 12. Configured. While the seedling take-out port guide 15 is attached to the frame part 14a, the end of the inner back side surface 17a of the opening forming part 17 is engaged, and the seedling take-out direction by the planting claws 12 is increased.
