Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for adjusting a seedling retainer on a seedling mounting table of a seedling transplanter such as a rice transplanter and a straw transplanter.

[Problems to be Solved by Conventional Techniques and Inventions] Generally, in this seed transplanter, a seedling table for mounting planted seedlings (for example, pine-shaped group seedlings) is provided in an inclined manner, and seedlings are fed from the lower end of the inclination. There are some that were transplanted to the field. However, when the planted seedlings are placed on such a slanted seedling mounting table, there is a fear that the placed planting seedlings may be turned up and buckled, so that the planted seedlings may be planted on the seedling mounting table. It has been attempted in the past to attach a seedling holder that holds the seedling from above.

However, the thickness of the planted seedlings varies depending on the type of seedlings, conditions for raising seedlings, etc., and it is necessary to adjust the seedling holding position (height) by the seedling holding body according to this.

Therefore, conventionally, adjusting ribs are individually provided on the partition ribs (which partition the left and right side edges of the seedling mount and adjacent seedling mounts) to project the seedling mount surface of the seedling mount, and this adjustment By attaching the tip of the seedling retainer to the rod so that the vertical height can be adjusted, the seedling retainer position can be adjusted. However, in this case, it is necessary to attach a dedicated adjusting rod, the number of parts is large, the assembly is troublesome, and the appearance is complicated, which is a problem.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an adjusting device for a seedling retainer in a seedling mounting table of a seedling transplanter, which can eliminate these drawbacks. In the seedling table of the seedling transplanter that is obliquely installed so that the seedlings are fed out from the lower end and transplanted to the field, a seedling holder for the planted seedlings placed on the seedling mounting surface is provided. In order to adjust the seedling holding position by supporting the tip end side to the seedling placing surface so that it can be adjusted up and down, the tip end of the seedling holding body was projected and formed on the seedling placing table to partition the seedling placing surface. The locking portion is formed so as to face the partition rib strip, while the locking portion is inserted into the upper surface of the partition rib strip, and an opening for receiving and supporting the inserted locking portion at the edge is opened. Further, a plurality of locking groove portions for locking the locking portion inserted from the opening are formed in the partition rib strip, It is characterized in that the selective locking of the locking portion to the locking groove portion for adjusting the seedling pressing position is performed within the partition rib strip while the locking portion is received and supported by the opening edge portion. It is what

With this configuration, the present invention locks the tip end portion of the seedling pressing body in the partition ribs for position adjustment so that the pressing position can be adjusted without the need for a dedicated adjusting rod. It was done like this.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a riding type traveling body, and a seedling planting section 3 is provided at a rear portion of the traveling body 1 via an elevating link mechanism 2.
Is equipped. Although the seedling planting unit 3 is configured using member devices such as the drive case 4, the planting claws 5, the float 6, and the seedling platform 7 that is inclined in a front high-rear low state, as is conventional. A seedling retainer 8 embodying the present invention is provided on the seedling mount 7.

That is, in order to partition each seedling mounting surface of the seedling mounting table 7, partition rib strips 9 are formed so as to project from the left and right side edges of the seedling mounting table 7 and a part that separates each seedling mounting surface. A seedling leaf retainer 10 is provided at the lower end of the inclined surface, and a seedling vertical feeding device 11 is arranged on each seedling mounting surface. Reference numeral 12 denotes a pair of seedling pressing rods constituting the seedling pressing body 8, and the lower end portion of the seedling pressing rod 12 is pivotally supported by the seedling leaf pressing member 10 so as to be vertically swingable. Then, the seedling pressing rod 12 is extended upward along the seedling mounting surface, the tip end is folded back in a substantially triangular shape, and the folded back end is an intermediate portion of the adjusting stay 13 formed in a substantially V-shape. Is integrally attached to. The left and right legs 13a of the adjusting stay 13 are configured so as to face the upper surface of the partition rib strip 9 at an appropriate position, and a lower end of the adjusting stay 13 is formed with a locking portion 13b bent upward.

On the other hand, at the position where the leg portion 13a of the partition rib strip 9 faces,
An opening 14 is formed in which the locking portion 13b can be inserted and removed freely, and the partition rib strip 9 in which the opening 14 is formed is formed.
A plurality of locking groove portions are formed therein in which the locking portion 13b can be selected and locked so as to move away from a position close to the seedling mounting surface.

That is, the opening 14 is partitioned in the tilt direction by the partition rib 14a, and the locking portion 13b is inserted from the first opening 14b on the lower side of the tilt. On the other hand, inside the partition rib strip 9 so that it can be seen from the second opening 14c on the upper side of the slope,
For convenience, three stages of locking ribs 9a, 9b, 9c are formed. In other words, the locking ribs 9a, 9b, 9c do not overlap with the tilting direction of the seedling placing table 7, and the farthest from the seedling placing surface, the ribs 9a, 9b, 9c are positioned on the upper end side of the tilting ribs so that the left and right side walls of the partition rib strip 9 are located. There is a step between them, and this locking rib 9
Between a, 9b and 9c, locking grooves A, B and C are formed stepwise so as to be distant from the position close to the seedling mounting surface. Then, the locking portion 13b inserted from the first opening 14b is pushed / pulled in the inclination direction of the seedling placing table 7 to selectively insert into any of the locking grooves A, B, C. The leg portion 13a of the locking portion 13b which can be locked and is inserted and locked has the partition rib 14a.
It is received and supported by elastically abutting from the lower end side of the slant, and by this, the seedling holding position of the seedling holding rod 12 can be adjusted.

In the embodiment of the present invention configured as described above, the planting seedlings placed on the seedling placing table 7 are pressed from above by the seedling retainer rod 12, which causes the planting seedlings to roll up. However, the pressing position of the seedling pressing rod 12 is adjusted in the partition ribs 9 that partition the seedling mounting surface of the seedling mounting base 7. Therefore, the space inside the partition rib strip 9 can be effectively utilized as it is, and it is not necessary to project the adjusting rod from the partition rib strip 9 as in the conventional case, and the number of parts can be reduced and the parts can be easily assembled. In addition, the appearance is smooth and comfortable.

Further, in this one, the locking ribs 9a, 9b, 9c are formed in a stepwise manner in the inclination direction, and each can be seen through the second opening 14c, and as a result, the pressing position of the seedling pressing rod 12 is adjusted. In this case, although the locking grooves A, B, C are formed in the partition rib strip 9, it is convenient that the pressing position can be immediately confirmed through the second opening 14c.

When adjusting the holding position, the locking portion 13b is pushed and pulled in the direction of inclination of the seedling mounting table to switch the locking position of the locking portion 13b with respect to the locking grooves A, B and C. Often, the seedling pressing position is adjusted in the partition rib strip 9, but the partition rib strip 9 has a locking portion 13b that is long in the inclination direction.
If the left and right width is enough to hold the pair of, the push-pull operation is performed in the left-right direction (direction orthogonal to the tilt direction) to lock the locking portion 13b in the locking groove portion. As described above, there is no need to secure a wide width of the left and right ribs, and it is convenient that the rib width of the partition rib strip 9 as it is can be surely locked.

Moreover, in this structure, the receiving support of the locking portion 13b is formed by the upper surface of the partition rib strip 9, that is, in the present embodiment, the partition rib 14a which is the edge of the first opening 14b on the lower side of the slope. Since the leg portion 13a is brought into contact with the partition rib 14a, the selective locking of the locking grooves A, B, C of the locking portion 13b is achieved, and as a result, the leg portion 13a is partitioned. The reliability of the adjustment work can be achieved without causing the operator to worry about the support of the seedling pressing rod 12 as in the case of being loosely fitted apart from the rib 14a.

This is particularly effective in the case of the second embodiment where there is no second opening and the engagement state cannot be visually observed. That is, as in the second embodiment shown in FIGS. 7 and 8, in which the locking portion unit 15 having the locking grooves A, B, C is integrally incorporated in the partition rib strip 9, , Locking grooves A, B, as in the first embodiment
Although C cannot be directly visually inspected, in this case, the set of the locking portion 13b can be easily confirmed.

[Operation and Effect] In short, since the present invention is configured as described above, the planted seedlings placed on the seedling mounting base are pressed from the upper side by the seedling retainer, and thus the planted seedlings are planted. Although it is possible to prevent the trouble of the curling up and down, the pressing position of the seedling pressing body is adjusted in the partition ribs that partition the seedling mounting surface of the seedling mounting base. Therefore, the space inside the partition ribs can be effectively used as it is, and it is not necessary to project the adjusting body from the partition ribs one by one as in the conventional case, and the number of parts can be reduced and the parts can be easily assembled. The appearance is smooth and comfortable.

In addition, when adjusting the seedling pressing position, this set may be set so that the locking portion is received and supported by the upper surface of the partition rib strip, whereby the locking portion is set in the locking groove portion. It will be in the set state where the locking is securely done, and as a result, the locking state with respect to the locking groove part will be unclear like the one that is set in the state where the locking part is separated from the upper surface of the partition rib strip. There is no concern about the support of the seedling retainer, and the certainty of adjustment work can be achieved.
