[Problem that the idea aims to solve]

In mat-shaped rice seedlings, the connection between the roots of the seedlings is relatively weak, so the planting claws are A seedling that is taken out when taking out a single seedling from a mat-like seedling while passing through the seedling take-out port. The roots of the seedlings remaining on the seedling stand separate relatively easily, and each seedling can be grown without any particular problems. It is taken out. On the other hand, the connections between the roots of rush grass seedlings are much stronger than in rice. Because the seedlings are resistant to (equivalent to the amount to be removed) and then put them all together again on the seedling stand. be. However, even if the seedlings are divided into individual plants and placed on the seedling stand, There is a risk that the roots of a single seedling may become intertwined with each other as they are fed through the vertical feed mechanism. There is. In such a situation, the planting claw will pass through the seedling take-out port and remove a single seedling. When taking out the seedlings, make sure that the roots of the seedlings to be taken out and the roots of the seedlings remaining in the seedling stand are sufficiently separated. The roots of the seedlings remaining on the seedling stand are dragged out by the planting claws. There is a risk that a situation may arise where the This invention allows a single seedling to be taken out without any problem when the planting claw passes through the seedling take-out port. The purpose is to configure it so that it can be done.

0004

[Means to solve the problem]

The feature of this invention is that the above-mentioned seedling transplanter is configured as follows. Ru. In other words, A seedling stand on which crop seedlings are placed, and a guide rail that supports the lower end of this seedling stand. , a transverse feed mechanism that drives the seedling tray to reciprocate transversely along the guide rail, and this transverse feed mechanism. The side of the first seedling near the seedling take-out port opened in the guide rail in conjunction with the feeding mechanism. The guard is driven back and forth between the entry position where it enters the seedling position and the retraction position where it leaves the seedling. A root divider that is equipped with a holding arm and enters both the left and right sides of the root of the seedling at the entry position. part is provided on the holding arm, and the holding arm is stopped or almost stopped at the plunged position. , pass through the seedling extraction port between the left and right root divisions, hold the seedling, and plant it in the field. When the planting claw reaches the end of the horizontal feed stroke, the seedlings on the seedling tray are removed. It is equipped with a vertical feed mechanism that feeds it to the idle rail side.

[0005]

[Effect]

With the configuration described above, for example, as shown in Figure 1, the As the holding arm 6 moves to the left in the drawing, the tip of the holding arm 6 moves as shown in FIG. rushes into the seedling A located at the seedling take-out port 12 of the guide rail 7, and this seedling A is removed from the seedling take-out port. It is pushed down a little toward the outlet 12 (corresponding to the insertion position of the holding arm 6). to this If the seedling A in the seedling take-out port 12 is about to float up, the seedling A will be held. It is returned to a predetermined position by arm 6. In this case, the left and right root division parts 6b of the holding arm 6 are on both left and right lateral sides of the root part A1 of the seedling A. enter the department at the same time. Therefore, due to the penetration of this root division part 6b, the roots of the seedling A The roots of the next seedling located next to A1 and the seedling take-out port 12 are separated to some extent. In this state of FIG. 2, as shown in FIG. 3, the planting claw 3a is attached to the root A1 of the seedling The root part A1 of the seedling A is held between the planting claws 3a through the left and right root dividing parts 6b, and the seedling is planted. The claw 3a passes through the seedling removal port 12. In this case, the root part A1 of the seedling A is located next to the seedling removal port 12 by the root dividing part 6b. Make sure that the roots of the next seedling are separated to some extent in advance, and that the guide rail Even if the seedlings remaining on the 7 side try to be dragged, this will be stopped by the root division part 6b. Therefore, even if the planting claw 3a is driven downward, the seedling A to be taken out is on the guide rail 7 side. The above-mentioned seedlings remaining in the seedlings are pulled away without any trouble, and the planting claws 3a Seedlings A are planted in the field.

[0006]

[Effect of the idea]

As mentioned above, the seedlings are not taken out all at once using only the planting claws, but are If you separate the roots of the seedlings that remain on the guide rail side from the roots of the seedlings that remain on the guide rail side, In addition, the roots of the seedlings remaining on the guide rail side are held in place by this root division. This allows the roots of the seedlings to be taken out and those remaining on the guide rail side to be separated without any problem. This prevents the remaining seedlings from being dragged along the guide rail side and prevents planting defects. I was able to prevent it. In addition, even if the seedlings taken out from the seedling take-out port are about to float up, the holding arm will hold them. This prevents the planting claws from failing to grip the seedling. Both can be prevented.

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. Figure 1 shows the overall side view of a rice seedling transplanter for rice grass, and shows the planting mission case 1. A crank arm 2 rotatably driven at the rear is equipped with a planting claw 3a and a seedling pushing part 3b. The planted planting arm 3 is attached to the top of the planting mission case 1. A holding arm 6 is attached to a pair of front and rear links 4 and 5. planting mission It is driven to slide back and forth along a guide rail 7 fixed to the top surface of the case 1. A seedling stand 8 is provided, and a plurality of sets of seedling take-out ports 12 are opened in the guide rail 7. It's being talked about. A float 13 is supported at the bottom of the planting mission case 1. A seedling transplanter for strawberry is constructed.

[0008] The seedling stand 8 is divided into parts corresponding to each planting row, as shown in Figures 1 and 4. A large partition plate 10 is provided in the partition part 9, and a bell is installed in the part corresponding to each planting row. It is constructed by providing a vertical feed mechanism 11 of the type shown in FIG. Seedlings A for strawberry grow into a mat shape. Once grown, Seedling A is divided into individual plants and then put together again into left and right partitions. It is placed between the plates 10.

[0009] Next, the holding arm 6 will be explained. As shown in Figures 1 and 2, the crankshaft A cam plate 18 is fixed to the support shaft 17 of the arm 2, and the planting mission case 1 side The support shaft 17, cam plate 18, and planting arm 3 move counterclockwise in the paper due to the power from Rotationally driven. Then, move this cam plate 18 and link 4 in the counterclockwise direction on the paper of FIG. The link 4 is driven to swing back and forth by the action of a spring (not shown) biased against the It is. As shown in FIGS. 2 and 3, the tip of the holding arm 6 has an upper left side. A pair of right holding claws 6a and a pair of left and right rod-shaped root dividing portions 6b are fixed to the lower side thereof. Ru.

0010 Next, the movements of the planting arm 3 and the holding arm 6 will be explained. Figure 1 shows the planting area. This is the state immediately after arm 3 has planted seedlings A in field G (holding arm 6 is in the retracted position). ). From this state, the support shaft 17 is rotationally driven in the counterclockwise direction on the paper. 1 and 2, the left and right holding claws 6a of the holding arm 6 are aligned with the guide rail. The seedling A enters the upper side of the root A1 of the seedling A located at the seedling take-out port 12 of the cell 7, and the seedling A is pushed down a little toward the seedling take-out port 12 side. And as shown in FIGS. 2 and 3, The left and right root division parts 6b of the holding arm 6 enter the left and right lateral sides of the root A1 of the seedling A. It is. Therefore, due to the penetration of this root division part 6b, the root part A1 of the seedling A and the seedling The roots of the next seedling located next to the outlet 12 are separated to some extent. then hold The arm 6 is stopped for a short time in the state shown in FIG.

[0011] In the case of FIG. 2, the planting claw 3a has reached just in front of the seedling removal port 12. stop 2 and 3 while the holding arm 6 shown in FIG. 2 is stopped. The claws 3a pass between the root A1 and the root dividing part 6b of the seedling A under the left and right holding claws 6a. The root part A1 of the seedling A is held between the planting claw 3a and the seedling pushing part 3b, and the planting claw 3a The seedling extrusion part 3b passes through the seedling take-out port 12.

0012 In this case, the root part A1 of the seedling A is located next to the seedling removal port 12 by the root dividing part 6b. Make sure that the roots of the next seedling are separated to some extent, and that the roots of the next seedling are separated to some extent, and that Even if the remaining seedlings try to be dragged away, they are stopped by the root division part 6b, so that they can be planted. Is the seedling A remaining on the guide rail 7 side even when the attachment arm 3 is driven downward? The seedling A passes through the guide 15 shown in Figure 1. The seedlings are planted in the field G using the planting claws 3a and the seedling pusher 3b.

[0013] After the holding arm 6 and planting arm 3 operate as described above, the seedling stand 8 moves to the guide rail. The seedlings are fed along the line 7 by a distance corresponding to the width of the seedling outlet 12. The operation of the holding arm 6 and the planting arm 3 and the horizontal feeding of the seedling stand 8 are repeated. It is. When the seedling tray 8 reaches the stroke end of the horizontal feed, the vertical feed shown in FIG. The seedling A on the seedling stand 8 is sent to the guide rail 7 side by the feeding mechanism 11.

[0014] As shown in FIGS. 1 and 4, the support shaft extends across the lower end of the partition plate 10 in the seedling stand 8. 14 is rotatably supported and is located above the portion corresponding to each planting row. Two guide rods 16 for holding down seedlings are fixed to the support shaft 14 so that the seedlings are held down. of seedlings A seedling holding plate 19 is arranged on the top of the seedling A in the stand 8. A guide rod 16 is passed through a pair of hook portions 19a at the upper end. This allows vertical As the seedling A on the seedling stand 8 is sent to the guide rail 7 side by the feeding mechanism 11, The seedling holding plate 19 moves toward the guide rail 7 together with the seedling A.

[0015] A contact switch 20 is installed at a position slightly above the bottom end of the partition plate 10. The number of seedlings A on the seedling tray 8 has decreased, and a part of the seedling holding plate 19 has been wiped out. When the switch 20 is touched, a buzzer (not shown) sounds and a lamp (not shown) flashes. It is configured so that In such a situation, workers should temporarily stop planting work. After stopping, lift up the guide rod 16 and seedling holding plate 19 shown in Fig. 1 to install a new seedling. While replenishing the seedlings A, lower the guide rod 16 and place the seedling holding plate 19 on top of the seedlings A. It is placed in
