Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling supply device for a rice transplanter, which reliably supplies seedlings from pine-shaped seedlings to the seedling planting device in a predetermined amount at a time, and effectively suppresses damage to the seedlings. The purpose is to make it possible to do so.

Next, embodiments of the present invention will be described based on illustrative drawings.

At the rear of the running aircraft, which is equipped with an engine E at the front, a control handle 1 at the rear, and wheels 2 that can be raised and lowered between them, three wheels are arranged in parallel in the lateral direction of the aircraft. A seedling planting device 3... and a seedling feeding device for the seedling planting device 3... are provided, and a pair of front and rear ground floats 4, 4 are provided below the traveling body, and a walking type for three-row planting is provided. It is configured as a rice transplanter.

The seedling supply device is constructed as follows.

That is, as shown in FIGS. 1 and 2, three pine-like seedlings are placed in parallel in the transverse direction of the machine body together with the resinous seedling-raising sheet 5 to be separately supplied to the seedling planting device 3. A seedling platform 6 equipped with a seedling loading section is provided above the control handle 1 so that it can be moved back and forth in the left-right direction of the machine by a sliding shaft 7, and the seedling platform 6 has a seedling platform 6 that can be moved back and forth in the left-right direction of the machine with respect to the seedling planting device 3. It is linked so that it can be moved back and forth with the movement. As shown in Fig. 4, the above -mentioned seedling sheet 5 is formed in a waveform, and the seedlings are equivalent to the cut part in the seedling of 3a with seedlings with seedlings 3a. A large number of protrusions 10 for forming grooves 8 on the bottom of the seedbed soil and recesses 9 on the bottom side of the sheet, and a continuous flat surface extending from one end to the other in the seedling feeding direction are used as a seedbed. A plurality of flat surface portions 11 for forming on the soil bottom surface are respectively provided on the inner bottom surface of the sheet, and as shown in FIG. 12
Then, the seedling planting device 3 engages the recessed portion 9 to place the seedling.
Rotating body 1 having claws 13a for transferring to the side
In order to separate the pine-shaped seedlings from the seedling-raising sheet 5 and to guide the separated pine-shaped seedlings to the seedling supply port by attaching the pine-shaped seedlings and the seedling-raising sheet 5 so as to be able to rotate together, with three of them corresponding to each of the seedling placement parts. A plurality of scrapers 14 are attached to the seedling stand 6 so as to act on the flat surface portion 11 individually. The sliding shaft 7 is configured to be reciprocated by a certain angle each time the seedling stand 3 reaches the left and right sliding stroke ends, and the rotating shaft 12 is configured to be rotated by a swing arm 15 and a push/pull rod 16. and a clutch 17 that transmits rotation in only one direction, the rotary body 13 is linked to the sliding shaft 7, and each time the seedling platform 6 reaches the left and right sliding stroke ends, the rotating body 13 moves the seedlings to the It is configured so that the groove 8 portion of the seedbed soil is positioned on the locus of movement of the seedling planting claw 3a by being driven by the rotational angle necessary to transfer the distance corresponding to the pitch between the grooves 8. . In other words, grooves 8 are formed in the seedbed soil so that the seedling planting device 3 can easily cut the bed soil, and furthermore, the grooves 8 are formed in the seedbed soil to prevent the bed soil from collapsing due to the grooves 8 and the seedling transfer force when transferring the seedlings. The seedlings are placed on the seedling stand 6 together with the seedling-raising sheet 5, and the sheet 5 is configured to maintain the shape of the seedlings, and the rotating body 13 is placed on the seedling-raising sheet 5.
In order to prevent the transfer force from directly acting on the seedlings, and furthermore, to prevent the seedbed soil from collapsing when the seedlings and the seedling-raising sheet 5 are separated,
The structure is such that seedlings are scraped up from the seedling growing sheet 5 using a scraper 14.

As shown in FIG. 3, a guide 18 for winding up the seedling-raising sheet 5 separated from the seedlings onto the rotary body 13 is attached to the lower surface side of the scraper 14, and a guide 18 is attached to the lower surface side of the scraper 14, and the seedling-raising sheet 5 is rolled up from the rotary body 13. A storage section 19 for the seedlings is provided below the seedling placement section so that the seedlings can be taken out from the sheet 5 without being damaged even by the separation action of winding up the sheet 5, and empty seedlings can be taken out. It is configured such that the sheets 5 are stored and stored.

As shown in FIG. 4, the seedling growing sheet 5 is provided with connecting portions 5a or 5b at both front and rear ends to connect with another seedling growing sheet 5, and as shown in FIG. Auxiliary conveyance rotating body 20,
21, and a seedling placement part step for connecting the connection part 5a of the subsequent seedling-raising sheet 5 to the connection part 5b of the preceding seedling-raising sheet 5, and a connection part pressing member 22 for placing the seedlings, respectively. By simply placing seedlings on the table 6 and replenishing the seedlings on the upper side of the seedling tray 6 in the direction of seedling transfer, the seedling raising sheet 5 of the replenished seedlings is automatically transferred to the seedling supply port side and It is connected to the seedling-raising sheets 5, and is configured to prevent troubles such as gaps between the seedling-raising sheets 5 and seedling supply mistakes.

Incidentally, instead of the rotating body 13, an endless rotating belt or the like may be used, and these are collectively referred to as the seedling feeding device 13.

Further, if the recessed portion 9 formed on the bottom surface of the sheet is used as the engaging portion of the seedling raising sheet 5 with respect to the seedling feeding device 13 as shown in the above embodiment,
It is advantageous to be able to save manufacturing time and to minimize the width of the sheet, but a dedicated one may be provided at an appropriate location such as a location laterally outward from the seedling.

In summary, the seedling feeding device for a rice transplanter according to the present invention forms grooves 8 in the width direction of the seedlings in the bottom surface of the soil in the seedling bed at positions corresponding to cutting points when taking out the pine-shaped seedlings by the seedling planting device 3. It is characterized in that it is configured to be placed on a seedling stand 6 together with a seedling raising sheet 5 formed into a corrugated shape, and a seedling feeding device 13 is provided in a state to engage with the seedling raising sheet 5.

In other words, since the grooves 8 are made in advance at the locations corresponding to cutting in the bed soil, the seedling planting device 3 can easily and accurately cut and take out a predetermined amount. The seedlings are placed together with the seedling-raising sheet 5, and the sheet 5 maintains the shape of the seedlings, and the seedling feeding device 13 is engaged with the seedling-raising sheet 5, so that the transporting force is not applied directly to the seedlings. This makes it possible to prevent the soil from collapsing due to the grooves 8 and the transport force that accompany the transfer of seedlings, and it has become possible to transfer the seedlings reliably and without damaging them at a predetermined feed rate. It is now possible to reliably supply seedlings to the device 3 in a predetermined amount while effectively suppressing damage to the seedlings, and to perform a good planting operation that suppresses irregularities in the amount of planted seedlings and missing plants. Summer.
