Description

[Detailed Description of the Invention] This invention relates to a width adjustment device for a seedling platform of a rice transplanter.

Conventionally, the seedling mounting table of a rice transplanter is provided with partition ribs for placing and partitioning seedlings according to the number of planting rows, but since the spacing between the partition ribs is constant, If the length of the width of the pine is not constant and is irregular, the seedlings will not easily slide and it will be difficult to cut the seedling blocks accurately, which may lead to the occurrence of stock defects.

In this invention, by adjusting the width of the partition ribs of the seedling stand, the width between the partition ribs of the seedling stand on which the seedling pine is placed can be adjusted, and the width of the seedling stand can be adjusted according to the variation in the width of the seedling pine. To provide a width adjustment device for a seedling platform of a rice transplanter which can prevent seedlings from missing by making the sliding of the seedling pine good and preventing the plant from missing.

To explain the embodiment of this invention in detail based on the drawings, A shows a walking-type four-row rice transplanter, in which a prime mover 1 is mounted on the front part of the machine body a, wheels 2 are provided on the left and right sides, and the machine body There is a float 3 at the bottom of the aircraft a, and a seedling stand 4 with a low front and rear height at the rear of the aircraft a.
is provided so as to be slidable laterally along the rail 17.

A seedling planting device 6 is provided at the bottom of the seedling platform 4, and a planting claw 7 connected to the device 6 allows seedlings to be planted.
Seedling blocks are cut from the seedling pine M on the seedling table 4 and planted in the field.

8 indicates a handle.

On the top surface of the seedling platform 4, end partition ribs 9, 9' are protruded from both left and right ends, and a partitioning rib 10 is protruded from the center of the top surface of the seedling platform 4 to divide the top surface of the seedling platform into four parts, so that the four seedlings can be separated. It is designed to allow mats to be placed on it.

The gist of this proposal is that the width of the partitioning rib 10 provided on the seedling stand 4 is adjusted.
The purpose is to adjust the width of the seedling pine placement space on the seedling placement stand 4, and is configured as follows.

That is, a vertical groove 11 is provided in the center of the seedling table 4, and a partition rib 10 is manufactured separately from the seedling table 4, and the partition rib 10 has a rib structure on both the upper and lower surfaces. Wide rib 1
0-1 narrow rib 10-2, and a fitting part 12 for fitting into the vertical groove 11 of the seedling stand 4 is provided in the continuous part of the wide rib and the narrow rib, that is, in the central part. The separate partition rib 10 is integrally attached to the seedling stand 4 by inserting the fitting part 12 of the partition rib 10 from the upper end opening of the vertical groove 11, and when it is attached, the wide rib 10-1 is inserted as appropriate. Alternatively, the width of the partition rib 10 is adjusted by installing the narrow rib 10-2 so as to be positioned above the seedling table surface.

13 is a groove bottom portion disposed below the vertical groove 11 of the seedling platform 4, that is, on the lower surface of the seedling platform 4;
It functions as a series of seedling stands divided into two by the vertical groove 11.

14 is a groove bottom 13 which is bisected by the vertical groove 11 and functions as a continuous installation of seedling stands.
This is a connecting flange for dividing the two into two and connecting them with bolts 15. The seedling platform 4 is configured to be able to be divided into each row, and the seedling platform 4 can be divided into two by the desired number of rows via the connecting flange 14. It is designed so that it can be connected to form the entire seedling stand, and it is possible to manufacture a seedling stand by connecting as many unit seedling stands according to the number of rows as necessary during the assembly work process of the rice transplanter. In another embodiment, it is also possible to divide the groove bottom 13 into two parts and connect the two halves with a bolt 16 via the partition rib 10.

In addition, there are wide ribs 10-1 and narrow ribs 1 on the upper and lower surfaces.
By providing several types of wide width and narrow width partition ribs 10 provided with 0-2, the width of the rib can be adjusted to a considerably large extent.

S indicates the seedling loading width of the seedling pine loading portion partitioned by ribs on the seedling loading table 4.

Reference numeral 17 denotes a guide rail having an L-shaped cross section for guiding the lateral sliding of the seedling platform 4;
A cutting groove 18 is provided in which the planting claw 7 can be inserted to cut the seedling block.

Reference numeral 19 denotes a narrowing portion provided at the lower end portion of the partition rib 10, and when a wide rib is used, the lower end of the rib interferes with the cutting groove 18 of the guide rail and interferes with the rotation of the planting claw 7. (See Fig. 5). Also, in order to prevent the partition rib 10 from interfering with the cutting groove 18, as another example, the lower end of the partition rib 10 and the guide rail 17 should be It is also possible to keep the lower end at an appropriate position when installing the partition rib 10 in order to maintain a constant gap l between the partition ribs 10. (See Figure 6).

20 is a seedling pine presser rod, and the presser rod is:
Both ends are supported and fixed to end partition ribs 9, 9' provided on both left and right sides of the seedling table 4, and the partition rib 10 in the middle is not used for supporting and fixing the seedling pine presser rod. (See Fig. 5). Another example of the structure of the seedling pine presser rod 20 is to use the same presser rod 20 as a double tube with the fixing screw 2.
In some cases, the width of the partition rib 10 of the seedling table is adjusted to adjust the width of the space for placing the seedlings. This is provided because it is necessary to extend or contract the length of the seedling pine presser rod 20 supported and fixed using the partition rib 10 when making adjustments.

22 is a seedling stopper, and like the seedling pine presser rod 20, the seedling stopper 22 can also be fixed to the end partition ribs 9, 9' (see Fig. 5) or by adjusting the expansion and contraction. If possible (6th
(see figure), etc., and the length of the seedling stopper can be expanded and contracted according to the width adjustment of the seedling pine placement space.

Reference numeral 23 denotes a vertical feed shaft arranged on the back surface of the seedling table 4, which drives a star wheel 23' provided in a slightly protruding state on the surface of the seedling table 4 to vertically feed the seedlings.

Reference numeral 24 denotes a seedling support rail, which supports the upper side of the seedling support 4 on the back surface of the seedling support 4.

In the embodiment described above, the width of the partition rib 10 itself is set in advance so that the width can be adjusted by replacing the rib 10.
As another example, the partition rib 10 is vertically divided into left and right ribs 10-a and 10-b, and a width adjustment mechanism 25 is interposed between the left and right ribs, and the width adjustment mechanism 25 is operated. In some cases, the width of the partition rib 10 itself may be adjusted by adjusting the gap between the left and right ribs.

That is, the left and right ribs 16-a and 16-b are attached to the seedling stand 4 with pins 26 so as to be able to slide in the horizontal direction, and there is a width adjustment mechanism between the left and right ribs 16-a and 16-b. As the mechanism 25, a turnbuckle type mechanism (see FIGS. 7 and 8) and a link lever adjustment mechanism (see FIG. 9) are provided to adjust the width of the partition rib 10 itself.

The embodiment of this invention is constructed as described above, and the seedling pine is placed on the seedling stand 4, the seedling planting device 6 is operated, and the seedling blocks are cut by the planting claws 7. This machine carries out the planting work, and the machine a is held on the water surface of the field by the float 3 and the planting work is carried out while traveling by the wheels 2, but there is an irregularity in the horizontal dimensions of the seedling pine when raising the seedlings. In other cases, such as when there are variations in seedling mat size due to seedling growing conditions such as open field or frame seedling raising, or when there is lateral expansion due to changes in the shape of seedling mats due to irrigation, etc., the seedling mat placement space between the partition ribs may be If the seedling pine cannot be accommodated, or if the seedling pine is fit but the vertical sliding is not smoothed by the partition ribs, the width of the partition rib 10 itself can be adjusted to create a space for placing the seedling pine that is appropriate for the horizontal dimension of the seedling pine. By forming a vertical slide of the seedling pine, the cutting of the block by the planting nails can be performed accurately, and it is possible to prevent the occurrence of stubble, etc.

According to this invention, in short, the width of the partition rib that partitions each row of seedling pine spaces on the seedling table of the rice transplanter is made expandable and retractable, and the width of the seedling pine placement can be changed. Even if the horizontal dimensions of the seedling mats vary due to circumstances, it is possible to create an appropriate space for placing the seedling mats and allow the seedlings to slide smoothly.Furthermore, the width can be adjusted according to the uneven horizontal dimensions of the seedling mats. When doing this, without changing the overall size of the seedling stand itself,
Since an appropriate space for placing the seedling mats can be created by adjusting only the width of the partition rib, it is possible to vertically feed the seedling mats by driving a member such as a star foil that is attached to the seedling platform or in contact with the seedling platform. The vertical feed shaft that supports the seedling table, the seedling table support rail that supports the seedling table on the upper back side, the guide rail that slides and guides the seedling table, etc. can be used as usual without having to adjust their lengths at all. This has the effect of making it possible to adjust the space for placing seedlings on the seedling stand using a simple method.
