Description

Description: [Industrial field of use] The present invention relates to an apparatus 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 Prior Art and Invention] Generally, in this seed transplanting machine, 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 that can eliminate these drawbacks. First, the first invention is a seedling placing table of a seedling transplanting machine that is obliquely arranged so as to feed seedlings from the lower end and transplant them to a field.
In order to adjust the seedling holding position by providing the seedling holding body for the planted seedlings placed on the seedling placing surface and supporting the tip end side of the seedling placing surface vertically adjustable, the tip portion of the seedling holding body is adjusted. In order to partition the seedling mounting surface, the partition ribs projectingly formed on the seedling mounting table are opposed to each other to form the locking portions, while the upper surface of the partition ribs has an opening for inserting the locking portion. Further, a plurality of locking groove portions for locking the locking portion inserted from the opening are formed in the partition rib strip, and the seedling pressing position is adjusted to the locking groove portion of the locking portion. It is characterized in that the selective locking of is carried out in the partition rib strip.

A second invention is to provide a seedling holder for a planted seedling placed on the seedling placing surface on a seedling placing table of a seedling transplanting machine that is obliquely installed so as to feed the seedling from the lower end and transplant it to the field. , To adjust the seedling holding position by supporting the tip side of the seedling holding surface so that it can be adjusted up and down, the tip of the seedling holding body is projectingly formed on the seedling placing table to partition the seedling placing surface. While forming a locking portion that faces the partition rib row and that extends along the inclination direction of the seedling mounting table, an opening for inserting the locking portion is formed on the upper surface of the partition rib row,
Furthermore, a plurality of locking groove portions that lock the locking portion inserted from the opening by displacing the locking portion in the inclination direction of the seedling mounting table are formed in the partition rib strips to adjust the seedling pressing position. It is characterized in that selective locking of the stopper to the locking groove is performed within the partition rib strip.

Further, according to the present invention, with these configurations, the tip end portion of the seedling pressing body is positionably adjustable in the partition rib strip, and 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 drawing, reference numeral 1 denotes a riding type traveling machine body, and a rear part of the traveling machine body 1 is equipped with a seedling planting section 3 via an elevating link mechanism 2. Although the seedling planting section 3 is configured using the 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-rear-low manner, as is conventional, A seedling holder 8 according to the present invention is provided on the seedling stand 7.

That is, in order to partition each seedling mounting surface of the seedling mounting table 7, partition ribs 9 are formed so as to project from the left and right side edges of the seedling mounting table 7 and the partitioning portion of 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 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, in the first embodiment shown in FIGS. 4 to 6, the opening 14 is partitioned in the inclination direction by the partition rib 14a, and the locking portion 13b is provided from the first opening 14b on the lower side of the inclination. It is configured to plug in. On the other hand, in the partition rib strip 9,
Three-stage locking ribs 9a, 9b, 9c are formed so that they can be seen through the second opening 14c on the upper side of the slope. That is, the locking rib 9
a, 9b, 9c do not overlap with the inclination direction of the seedling placing table 7 and are located in a stepped shape between the left and right side walls of the partition ribs 9 so that the ones farther from the seedling placing surface are located on the inclined upper end side. 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 planted seedlings placed on the seedling placing table 7 can be prevented from the trouble of 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 stepwise 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.
It is enough if the left and right width is enough to store the pair of, and when the pushing and pulling operation is performed in the left and right direction (direction orthogonal to the tilt direction), the locking portion is locked in the locking groove. 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.

Further, in order to adjust the pressing position by inserting the locking portion 13b into the partition rib strip 9 in this way, as in the second embodiment shown in FIGS. Locking groove A, B, C
It is also possible to integrally incorporate the engaging unit 15 having the engaging portion formed therein, and to engage the engaging ribs 9a, 9b, 9c with the engaging portion 13b as in the third embodiment shown in FIG. It may be formed in a substantially inverted L shape so as to receive and support the tip.

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

[Effects] In summary, since the present invention is configured as described above, it is possible to prevent a problem that the planted seedling placed on the seedling placing table is turned upside down by the seedling retainer. But,
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 individually provide an adjusting tool for locking the seedling retainer from the partition ribs as in the conventional case, and the number of parts can be reduced. As a result, the parts can be easily installed and the appearance is simple and clutter-free.

Moreover, when adjusting the presser position, the locking part is pushed and pulled in the tilt direction of the seedling table to switch the locking position to the locking groove of the locking part. Although the position is adjusted within the partition rib strips, the partition rib strips need only have a left-right width that can hold a pair of locking parts that are long in the tilt direction, and a push-pull operation in the left-right direction. There is no need to secure a wide left and right rib width as in the case of locking the locking portion to the locking groove portion,
It is convenient that the rib width of the partition rib strip as it is can be surely locked.
