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 table, there is a fear that the planted seedlings placed on the seedling table may be turned upside down and buckled. It has been attempted in the past to attach a seedling retainer.

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. While forming the locking portion so as to face the partition rib strip, an opening is formed in the upper surface of the partition rib strip for inserting the locking part, and further, the opening is inserted into the partition rib strip from the opening. A plurality of locking groove portions for locking the locking portion are formed in a stepped shape, and the locking portion for adjusting the seedling pressing position is provided. The present invention is characterized in that the selective locking in the locking groove portion is performed stepwise in the partition rib strip.

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 portion that separates each seedling mounting surface. A seedling leaf retainer 10 and a seedling retainer 10a are provided at the lower end of the inclined surface, and a seedling vertical feeding device 11 is provided on each seedling mounting surface. Reference numeral 12 denotes a pair of seedling pressing rods which constitute the seedling pressing body 8, and the seedling pressing rods
The lower end of 12 is pivotally supported on the seedling leaf retainer 10 so as to be vertically swingable. The seedling pressing rod 12 is extended upward along the seedling mounting surface, the tip end thereof is folded back in a substantially triangular shape, and the folded back tip is formed in a substantially U-shape.
It is integrally attached to the middle part of 13. This adjustment stay 13
The left and right legs 13a are configured so as to face the upper surface of the partition rib strip 9 at an appropriate position, and the lower end thereof is formed with a locking portion 13b that is 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 locking groove portion is formed in a complicated manner in which the locking portion 13b can be selected and locked so as to be moved away from a position close to the seedling mounting surface.

That is, in the first embodiment shown in FIG. 6, the opening 14 is partitioned in the inclined direction by the partition rib 14a, and the locking portion 13b is inserted from the first opening 14b on the lower side of the inclination. Has been done. On the other hand, in the partition rib strip 9, three locking ribs 9 are provided so that they can be seen through the second opening 14c on the upper side of the slope.
a, 9b, 9c are formed. That is, the locking ribs 9a, 9b, 9
c is formed in a step-like manner between the left and right side walls of the partition rib strip 9 so that it does not overlap with the tilting direction of the seedling mounting table 7 and is positioned on the upper end side of the slope as it is farther from the seedling mounting surface. The locking grooves A, B, C are formed stepwise between the locking ribs 9a, 9b, 9c 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 and pulled toward the inclination direction of the seedling placing table 7 to selectively insert into any of the locking grooves A, B, C. The seedling holding rod 12 can be locked so that 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 can be prevented from being lifted up by the seedling holding rods 12, but this seedling holding rod The pressing position adjustment of 12 is performed within the partition ribs 9 that partitionally form 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 the locking ribs 9a, 9b, 9c are integrally formed with the seedling placing table 7 by molding by forming the stairs in this way, it is formed by a simple one using a front and back side split mold. As a result, it is not necessary to attach the locking ribs 9a, 9b, 9c to the seedling table 7 afterwards, and the assembling property can be improved.

Then, when adjusting the presser position, by pushing and pulling the locking portion 13b toward the inclination direction of the seedling mounting table, the locking position can be switched to the locking grooves A, B, C of the locking portion 13b. Of course, although the seedling pressing position is adjusted in the partition rib strip 9, it is sufficient if the partition rib strip 9 has a left-right width that can hold a pair of locking portions 13b that are long in the tilt direction. The width of the left and right ribs does not need to be as wide as in the case of pushing and pulling in the left-right direction (direction orthogonal to the tilt direction) to lock the locking portion in the locking groove, and it is the same as before. It is convenient that the rib width of the partition rib strip 9 can be surely locked.

Further, in order to adjust the pressing position by inserting the locking portion 13b stepwise into the partition rib strip 9 in this manner, the locking ribs 9a, 9b, as in the second embodiment shown in FIG. 9c, locking part
It may be formed in a substantially inverted L shape so as to receive and support the tip of 13b.

Needless to say, the present invention is not limited to these embodiments, and the number of engaging groove portions may be two or four, and any appropriate number can be provided.

[Operation and Effect] In short, since the present invention is configured as described above, the planted seedlings placed on the seedling mounting table can prevent the problem that the seedling pressing body is turned upside down. The pressing position of the seedling retainer is adjusted in the partition rib strip that partitions the seedling mounting surface of the seedling mounting table. Therefore, the space in the partition rib strip can be effectively used as it is, and As described above, it is not necessary to project the adjusting body from the partition ribs one by one, the number of parts can be reduced and the assembling of the parts can be facilitated, and the appearance is not complicated and the product is sleek.

Moreover, in this product, the locking of the seedling retainer within the partition ribs is formed in a step-like manner, and as a result, the seedling mounting table is integrated with the locking groove using a simple front and back split mold. It can be molded, and it is not necessary to form the locking groove portion on the seedling mounting table afterwards, so that the assembling property can be remarkably improved.
