Description

[Detailed description of the invention] The present invention relates to a seedling raising box for a transplanter, which is capable of forming seedlings of onions, kanranchi, etc., grown in a lattice pattern, so that each plant can be separated as a top-mounted block seedling. The purpose of this system is to provide a system that guarantees that seedlings are not disturbed when they are placed on a seedling supply table and transported.
In order to achieve this purpose, in a bottomed seedling box that is partitioned into a lattice of vertical and horizontal plates, one of the vertical and horizontal plate groups is arranged and fixed to the bottom plate, and the other of the vertical and horizontal plate groups is arranged and fixed to the surrounding frame. The bottom plate and the peripheral frame are fixed to each other so that they can be connected and separated, and one of the vertical and horizontal plates arranged and fixed to the bottom plate is parallel to each other and has a flat vertical surface, and is arranged and fixed to the surrounding frame in a row. The other vertical and horizontal plates are parallel to each other, and a notch retaining part is formed at a distance in the longitudinal direction of the plate to which the plate on the bottom plate side is engaged and detached. As a result, they succeeded in developing a seedling growing box for use in a transplanter, which features water holes formed in the bottom plate.

EMBODIMENT OF THE INVENTION Hereinafter, an example of the seedling raising box of the present invention will be described in detail with reference to the drawings, and an outline of a transplanting machine that uses the seedling raising box will be explained in detail.

Figures 1 and 2 show the seedling raising box of the present invention, 1 is a rectangular bottom plate, and on this bottom plate 1 one of vertical and horizontal plates (in the figure, a plurality of horizontal plates 2) are arranged and fixed in rows at predetermined intervals. has been done.

Reference numeral 3 denotes a rectangular peripheral frame, one of which has a vertical and horizontal plate shape, into which the rectangular bottom plate 1 is fitted; in the figure, a plurality of vertical plates 4 are arranged and fixed in rows at predetermined intervals.

The horizontal plates 2 are parallel to each other and have flat elevations,
The vertical plates 2 are parallel to each other.

Both 1 and 3 of the rectangular bottom plate 1 having two groups of horizontal plates and the rectangular peripheral frame 3 having vertical plates 4 are combined so that they can be connected and separated, but in the specific example, the lower edge of the vertical plates 4 has a horizontal plate. Cut engagement portions 5 are formed in the longitudinal direction of the vertical plate body 4 by buttoning them at equal intervals to the row spacing of the bodies 2;
The horizontal plate body 2 is fitted and engaged with each of the engaging portions 5 to connect the rectangular bottom plate 1 and the rectangular peripheral frame 3 in a separable manner.

In the illustrated case, the height of the vertical plate 4 is set to be smaller than the height of the horizontal plate 2, and the cut depth of the cut engaging portion 5 is set to be deep enough to receive the horizontal plate 2. ing.

In addition, as shown in Fig. 2, it is preferable to have a sword in which a drainage hole or slit 6 is formed between the horizontal plates 2 of the square bottom plate 1, and the slits 6 may be plural or singular, preferably even. distribute.

Further, although not shown in the drawings, it is preferable that the peripheral frame 3 is provided with a handle in consideration of the fact that the square bottom plate 1 and the square peripheral frame 3 can be combined and separated.

Contrary to the above button and the illustrated example, the retaining portion 5 may be formed on the horizontal plate 2, or the engaging portion 5 may be formed on both the vertical and horizontal plates 2.4.

However, preferably, the plate body fixed to the bottom plate 1 has an engaging portion 5.
It is preferable not to form.

Thus, one seedling is placed in each square partitioned into a lattice shape by the vertical and horizontal plates 2 and 4 by placing soil in a bottomed seedling-growing box made by combining the square bottom plate 1 and the peripheral frame 3. After that, the third
Planting is done using the transplanter shown below.

In FIGS. 3 and below, reference numeral 10 denotes a transplanter, which is attached to a tractor (not shown) and is towed in the direction of arrow F in FIG.

Reference numeral 11 denotes a seedling mounting table, which is shown as a conveyor type that circulates in the figure, and is provided on the machine frame 12.

Reference numeral 13 denotes a seedling extrusion device, which is provided above the seedling mounting table 11. In the figure, it is shown as a conveyor type that circulates, and two extrusion bodies 14 are provided in the longitudinal direction of the band.

The seedlings grown in the seedling raising box described above are separated from the surrounding frame 3 and the bottom plate 1, and the bottom plate 1 is placed on the seedling mounting table 11 with the seedlings A with soil remaining on the bottom plate 1.

At this time, the vertical plates 4 are arranged in a row on the peripheral frame 3, and the horizontal plates 2 are arranged in a row on the bottom plate 1, so when the two parts 1.3 are separated, the vertical plates 4 The attached seedlings A are divided into blocks for each plant.

Thus, the horizontal plate 2 is placed on the seedling mounting table 11 so that the longitudinal direction of the horizontal plate 2 is parallel to the extrusion direction of the seedling extrusion device 13.

Reference numeral 15 denotes a seedling sorting device, which is installed at the extrusion end area of the seedling extrusion device 13 so that a pair of conveyors 15a circulate around the vertical axis. It is set up so that you can find it.

16 is a seedling feeding conveyor located below the seedling sorting device 15.
The seedling feeding conveyor 16 is arranged so that the front half thereof overlaps the rear part of the seedling sorting device 15 as shown in FIGS. 3 and 4.

There is a pair of guide plates 17 on the seedling conveyor 16.
is the provision.

Reference numeral 18 denotes a seedling planting device, and the figure shows a device in which holders 19 that can be opened and closed at equal intervals in the circumferential direction are provided on a planting disk 20 that rotates around the horizontal axis, and is installed in the transfer end area of the seedling conveyor 16. It is.

Reference numeral 21 denotes a furrowing device, which is provided in front of the device 18 for planting seedlings, and although the figure shows a shoe-type device, it may also be a disk-type device.

Reference numeral 22 is a pair of earthen pots on the left and right, and the planting device 18 is installed slightly behind the Japanese film side.

Reference numeral 23 denotes a pair of left and right contact wheels for setting the groove depth, and for driving the seedling feeding conveyor 16 and the seedling planting device 18 synchronously by winding transmission bodies 24, 25, etc.

In addition, 26 is a detector, and when one of the seedling pushing bodies 14 comes into contact with this, the seedling mounting table 11 is intermittently fed by one pitch of the horizontal plate body 2, and at this time, the other seedling pushing body 14 is moved to the pushing start position. In this case, it should engage the soil of the seedling A with soil as shown in FIG.

Therefore, the seedlings grown in the seedling raising box of the present invention are placed on the seedling mounting table 11 in a state where each plant is divided into blocks on the bottom plate 1, and the extruding body 14 of the extruding device 13 It is pushed out by circulating around in a state where it is engaged with the soil of A.

During this extrusion, as shown in Figures 5 and 6, especially Figure 6, the horizontal plate body 2 fixed to the bottom plate 1 functions as a guide for the row of soiled seedlings A, and the soiled seedlings A are kept in the correct posture. It will be sent out below.

The seedlings A with soil are extruded, and their stems B are held by the conveyor 15a of the seedling sorting device 15 and sequentially transferred to the seedling feeding conveyor 16.

If you press the button on seedling A with soil and there is no stem B, even if there is stem B, the diameter is small or the height is low, conveyor 1
At 5a, the seedlings are sorted if they are not transported while being suspended or they fall due to the weight of the soil during transport.

Therefore, the single seedling raising box of this invention is advantageous in that it is possible to separate each plant individually during seedling selection.

The seedlings transferred by the seedling conveyor 16 are held at their stems B by the holder 19 which is open in the waiting area at the end of the transfer, and are dropped into a ditch with the soil facing down to be covered with soil. It will be covered with soil on the 22nd.

As mentioned above, in the present invention, one of the partition plates is fixed to the peripheral frame of the bottomed seedling nursery box, and the other partition plate is fixed to the bottom plate, and the peripheral frame and the bottom plate are combined so that they can be connected and separated. With the bottom plate removed and the seedlings with soil left on the bottom plate, the bottom plate can be placed on the seedling mounting stand, which is extremely convenient for use with a transplanter. In addition to the advantage of serving as a guide, it also has the advantage that the seedlings with soil are divided into blocks when the surrounding frame is removed.

In particular, since the dividing plates, that is, the bottom plates in which one of the vertical and horizontal plate groups is arranged parallel to each other, and the peripheral frame, in which the other side is arranged in parallel to each other, are combined so that they can be connected and separated, it is possible to combine them. When raising seedlings, each square is independent, and the root hairs of the seedlings do not invade adjacent squares, allowing independent seedlings to grow evenly. Since the vertical surfaces of the separating plates are flat and parallel to each other, the seedlings can be fed smoothly without deformation or collapse, and this is consistent with the uniform growth of the seedlings. Planting the seeds manually has the advantage of improving accuracy.

In addition, since water holes are formed in the bottom plate that correspond to each square, each square grows evenly, which has the advantage of reducing root dieback and root erosion.
