Description

[Detailed description of the invention] This invention is based on a sliding guide rail that is equipped with a seedling receiving surface that slides against the lower end surface of the seedlings placed on a seedling stand in an inclined position that reciprocates from side to side. This invention relates to a seedling supply device for a rice transplanter, which has a plurality of seedling supply ports for the seedling planting claw of the rice transplanter, and is provided with a seedling stopper that can freely stop and release the seedling slide on the upper side of the supply port for the seedlings placed on the seedling platform.

In order to enable planting of fewer rows than the number of rows for which the rice transplanter is equipped, so-called fractional row planting, the rice transplanter is installed on the upper side of the seedling supply port to prevent the seedlings from being fed to the seedling planting claw. However, conventionally, in order to move the placed seedlings to a predetermined position where they should be stopped, the seedlings had to be manually lifted or configured to lock the seedlings. In any case, the transporting force acts locally on the seedlings, resulting in damage to the seedlings, such as the leaves of the seedlings being cut or the soil being soiled.

The purpose of the present invention is to enable the movement of placed seedlings without damaging the seedlings, and to provide a structure for this purpose that can be easily modified.

The characteristic configuration of the present invention is that in the seedling feeding device of the rice transplanter mentioned above, the seedling stopper is configured to be able to freely stop and release the seedling slide for each row, and the seedling receiving surface In order to move to a position above the operating trajectory of the claw, the sliding guide rail is provided so that it can be adjusted vertically and fixedly operated along the seedling sliding direction, and its functions and effects are as follows. .

That is, by slidingly adjusting and fixing the sliding guide rail in a region where the seedling receiving surface is below the area where the seedling planting claws cut out, the amount of seedlings taken out by the seedling planting claws can be completely removed. The rows can be changed and adjusted to a constant value. When planting fractional rows, set the sliding guide rail so that its seedling-receiving surface is located above the cut-out area, and then set the seedling stopper of the row that will not be planted to the seedling-stopping state. By setting and then returning the sliding guide rail to the lower position, a fractional row planting mode can be set.
At this time, since the seedlings are pushed up on the entire seedling receiving surface, the bed soil does not collapse.

As a result, by using the sliding guide rail as both a device for adjusting the amount of seedlings taken and a device for pushing up and moving the seedlings, it is possible to move the seedlings in a stable state without causing the seedlings to collapse, etc., with only simple structural improvements. It came to this.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a seedling planting arm is attached to each of four locations in parallel in the lateral direction of the machine at the rear of the machine, which includes the planting transmission case 1, etc., via a drive rotation arm 2 and a swing link 3. 4 is attached to be swingable so that the seedling planting claw 5 can rotate up and down, and a seedling stand 7 on which pine-shaped seedlings 6 to be separately supplied to the seedling planting arm 4 are placed in four rows. a notch 8 that forms a seedling supply port for the seedling planting claw 5, a seedling tray sliding guide rail 10 having a seedling receiving surface 9 that acts on the lower end surface of the placed seedling, and the upper end of the support 11. It is configured to be attached so as to be slidable from side to side, and to be moved back and forth from side to side in conjunction with the seedling planting arm 4 in conjunction with the seedling planting movement of the seedling planting claw 5. Attaching the grounding float 12 and further arranging the fertilizer tank 13 in front of the seedling stand 7,
The fertilizer feeding rotary body 14 of the tank 13 is linked to the swing ring 3 via the rod 15 so as to be driven by the driving force of the seedling planting arm 4, and the fertilizer supply hose from the rotary body 14 is connected to the swing ring 3 through the rod 15. 16 is connected to the groove-making device 17, which is placed under the machine so as to make a groove in the muddy soil area located near the planting area and supply fertilizer, thereby making it possible to plant 4 seedlings and to plant the seedlings. The seedling planting device is designed to perform the fertilization work associated with this process. This seedling planting device is connected to the rear of a riding tractor in a state in which the power is transmitted from the tractor to form a riding type rice transplanter.

As shown in FIGS. 1 and 3, three action rods 18 act on the top surface of the soil on which the seedlings 6 are placed on the seedling stand 7.
a... and connecting rods 18 for these working rods 18a.
A seedling stopper 18 consisting of a A sliding operating tool 20 is attached to one support 19a or 19b of each of..., and four seedling stoppers 18 are individually operated to prevent the placed seedlings 6 from being supplied to the seedling supply port 8. It is configured so that it can be switched between a descending working position in which the seedlings 7 and the working rods 18a are held and stopped, and a releasing position in which the placed seedlings 6 are raised to allow descent, so that fractional row planting is possible. , the supply of seedlings to the four seedling planting claws 5 . . . can be stopped individually.

As shown in FIGS. 1 and 2, the connecting portion 10a of the guide rail 10 to the support 21 is
The operating lever 25 is slidably attached to the support 21 by a bolt 22 slidably inserted into the elongated hole, and is linked to the connecting portion 10a via the swing arm 23 and the rotating shaft 24. Depending on the operation,
The guide rail 10 is slidably adjusted relative to the seedling table 7 in the direction of approaching and separating from the operating trajectory T of the seedling planting claw 5, and the operating lever 25 is inserted and locked in the notch of the lever guide 26. By doing so, the guide rail 10 can be fixed at the adjusted position. That is, by operating the operating lever 25 within the operation range S, the seedling supply port 8 of the seedling planting claw operation locus T is located in the region where the seedling receiving surface 9 is located below the seedling planting claw operation locus T. The amount of seedlings removed by the seedling planting claws 5 is changed by changing the penetration depth. When planting fractional rows, the operating lever 25 is operated to the operating position A to slide the guide rail 10 toward the upper end of the seedling stand 7, and as shown in FIG. is pressed and moved by the seedling receiving surface 9 to a predetermined position where the seedling stopper 18 should act, that is, a position where the lower edge of the seedling has moved toward the upper end of the seedling platform 7 than the seedling planting claw operation locus T, and the seedling is planted. actuate the seedling stopper 18 corresponding to the seedling planting claw 5 that does not allow
Next, the operating lever 25 is returned to the operating range S, and the guide rail 10 is moved along the seedling planting claw operating trajectory T so that seedlings are supplied to the seedling planting claw 5 that is to be planted. is returned to the position where it will be located within the seedling supply port 8.

In addition, 27 or 28 shown in FIG. 3 is the seedling stand 7.
The horizontal side wall 7a or the seedling partition wall 7b of the receiving surface 9
These members are attached to the horizontal side wall 7a or the partition wall 7b so as to be freely retractable so as to allow the guide rail 10 to slide, and their projecting ends are attached to the receiving end. It is urged to protrude so as to come into contact with the surface 9.

The present invention can also be applied to a walking rice transplanter.
