Description

[Detailed description of the invention] Industrial application field The present invention is to easily and quickly perform seedling feeding work in a rice transplanter in which a seedling stand on which pine-shaped seedlings are placed is tilted toward the seedling outlet side. The present invention relates to a seedling feeding device that is capable of providing seedlings.

Conventional technology Conventionally, in this type of rice transplanter, planting work is carried out by placing pine-shaped seedlings on a seedling platform. Either the pine-like seedlings were scooped up and placed on a seedling stand, or the pine-like seedlings in the seedling box were moved onto the seedling stand by the seedlings.

Problems that the invention aims to solve By the way, with the conventional seedling supply method as described above, when taking out the pine-shaped seedlings from the seedling nursery box, the seedbed may be destroyed, and there is a risk that the seedling leaves may be damaged. However, there are problems such as the work is time-consuming and labor-intensive.

The present invention has been developed in view of the problems of the conventional ones.
An object of the present invention is to provide a seedling feeding device for a rice transplanter that can easily and quickly feed pine-shaped seedlings from a seedling box to a seedling stand without destroying the seedling bed or damaging the seedling leaves. That is.

Means for Solving the Problems The present invention has the following technical means for achieving its purpose.

In other words, the seedling feeding device for a rice transplanter according to the present invention is a rice transplanter in which a seedling platform for placing pine-shaped seedlings is inclined toward the seedling outlet side, and a seedling growing box is set on the top surface of the seedling platform. It is characterized in that a protrusion in the front-rear direction is provided that protrudes upward from a notch hole provided in the seedling-raising box and pushes up the pine-shaped seedlings, and that the height of the protrusion is increased toward the lower side of the slope. be.

Function To supply pine-shaped seedlings to the seedling stand of the rice transplanter,
Set up the seedling box in which the pine-shaped seedlings have grown. When the seedling raising box is set on the seedling stand in this way, the protrusion provided on the top surface of the seedling stand protrudes from the cutout hole of the seedling raising box, and since the height of the protruding part is higher on the downward slope side, the pine The shaped seedlings are pushed up high from the front end side and smoothly separated from the seedling box. Since the seedling platform is inclined toward the seedling removal port, the pine-shaped seedlings pushed up as described above are moved to the seedling removal position on the seedling platform and placed thereon.

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

In FIG. 1, 1 is a rice transplanter, and 2 is a seedling stand. 3 is a seedling planting device, and 4 is a handle. The seedling platform 2 is provided in an inclined manner on the side of the seedling outlet 5. The seedling take-out port 5 is formed in an apron 6 opposite to the inclined lower end of the seedling platform 2.

As shown in FIGS. 2 to 4, the seedling platform 2 has a slanted lower half serving as a seedling mounting section 7, and an upper half thereof serving as a seedling supply section 8. The seedling supply unit 8 has a plurality of ribs in the front and back direction at appropriate intervals between the left, right and middle partition ribs 9, 9, 10, that is, a protrusion 1 that pushes up the pine-shaped seedlings.
1 is formed, and this protrusion 11 is attached to a seedling stand 2.
The height increases sequentially from the upper end of the slope toward the lower end of the slope. The sloping upper end side of the seedling platform 2 is open. Guide springs 12 are attached to the left, right and middle partition ribs 9, 9, 10. 13 is its mounting pin. A seedling feeding rotary body 14 is provided on the bottom surface of the seedling mounting section 7.

A seedling raising box 15 is shown in FIG. This seedling raising box 15 can be freely inserted into the seedling supply 8 of the seedling platform 2 from its sloping upper end side. The seedling box 15 has a bottom surface and front and rear end surfaces.
A plurality of notch holes 16 are formed. This cutout hole 16 corresponds to the protrusion 11 of the seedling stand 2 that pushes up the seedlings.

In the device configured as described above, pine-shaped seedlings are grown in the seedling growing box 15. To supply pine-shaped seedlings to the seedling platform 2 of the rice transplanter 1, insert the seedling raising box 15 in which the pine-shaped seedlings have been grown from the sloping upper end side of the seedling platform 2 as shown in FIG. Since a notch hole 16 is formed in the box 15 in correspondence with the protrusion 11 of the seedling stand 2, the protrusion 11 of the seedling stand 2 passes through the notch hole 16 and protrudes upward, as shown in FIG. Push up the pine-like seedlings as shown. and protrusion 11
The height of the seedlings gradually increases toward the downward slope side, so as the seedling growing box 15 is inserted, the pine-like seedlings are gradually pushed higher from the front end side and smoothly separated from the seedling growing box 15. Next, when the pine-shaped seedlings are pushed up to the height of the front end surface of the seedling raising box 15 as shown in FIG. It is moved to the 7 side and placed. In addition, after the pine-shaped seedlings are supplied onto the seedling platform 2, the seedling growing box 15 is pulled out to the rear of the seedling platform 2 and removed.

In this way, in order to supply pine-shaped seedlings from the seedling nursery box 15 to the seedling tray 2, the pine-shaped seedlings can be transferred by placing the whole seedling nursery box 15 on the seedling tray 2, without breaking the seedling bed or removing the pine-shaped seedlings from the seedling tray 2. The work can be done easily and quickly without damaging the machine.

FIG. 10 shows another example of the seedling raising box 15. That is, the seedling raising box 15' of this example has a cutout hole 16' formed only in the bottom surface thereof. Therefore, in order to supply pine-shaped seedlings from this seedling growing box 16' to the seedling platform 2, the seedling growing box 16' must be moved from the seedling platform 2.
The pine-shaped seedling is pushed up by placing it on the seedling supply unit 8 and pushing down, and the operation of transferring the pine-shaped seedling to the seedling platform 2 as described above is performed. In this embodiment, the guide springs 12 for the left, right and middle partition ribs 9, 9, and 10 are not provided.

Effects of the invention The present invention is a rice transplanter in which a seedling stand on which pine-shaped seedlings are placed is tilted toward the seedling outlet. A protrusion in the front-rear direction that protrudes upward from the cutout hole and pushes up the pine-shaped seedlings is provided, and the height of the protrusion is made higher toward the lower side of the slope, so that the seedlings can be fed to the seedling stand. In this case, simply set the seedling box in which the pine-shaped seedlings have been grown on the seedling stand, and the protrusion that protrudes from the notch hole and is higher on the downward slope side will push up the pine-shaped seedlings from the front end and smoothly lift them out of the nursery box. Since the seedlings are separated, the work of supplying the seedlings can be performed extremely simply and quickly, and the seedling bed does not collapse or the seedling leaves are damaged.
