Description

[Detailed Description of the Invention] The present invention relates to a preliminary seedling mounting table for a rice transplanter, and more particularly to a preliminary seedling loading table having a plurality of upper and lower stages of loading tables.

In this type of spare seedling mounting table, the spare seedlings are placed on the holding table on a thin plate-shaped seedling placing plate, so the seedlings tend to slip due to the shaking of the machine, especially when the seedlings are In the case of square-shaped mat seedlings, they may slip and become misaligned in the narrow left and right directions.

If the placement position of the seedlings shifts in this way, when replenishing the seedlings, the spare seedling placement table must be placed in communication with the end of the seedling placement table on the rice transplanter side, and the spare seedlings can be transferred from the placement table onto the seedling placement table. When sliding the seedlings in, the communication position of the seedlings would be shifted, which would not only hinder the supply of seedlings but also cause damage to the seedlings.

In view of these points, the present invention aims to provide a spare seedling mounting stand for a rice transplanter that is improved so as to prevent the seedlings from sliding sideways with a simple structure when the spare seedlings are placed on the holding stand. This is the purpose.

For this purpose, the present invention has a multi-tiered state in which the upper tier spare seedling mounting table is spaced upwardly from the lower tier spare seedling mounting table by means of a link member, in configuring the auxiliary seedling mounting table in multiple upper and lower stages. The link member is movably supported at a seedling replenishment position that descends to near the position height of the lower reserve seedling mounting table and communicates with the end of the seedling mounting table, and the link member is connected to the upper preliminary seedling mounting table. When supported in the multi-tiered state, the mounting table is characterized in that it is configured to include protrusions that protrude upward from at least both sides of the upper stage mounting table.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings.

The riding rice transplanter shown in FIG.
are connected.

In the planting section 3, a seedling platform 6 on which mat-shaped seedlings are placed is tilted backwards and reciprocated left and right on a machine body 5 equipped with a float 4 that slides on the rice field surface, similar to a conventionally known rice transplanter. A planting body 7 is mounted so as to move up and down in opposition to the inclined lower end of the seedling platform 6, and the seedlings on the seedling platform 6 are moved one by one by such a planting body 7. The plants are cut out one by one and planted in the fields.

The link mechanism 2 includes two parallel links 9 and 10 between the rear end of the vehicle 10 body 3 and the front end of the body 5 of the planting work section 3.
is mounted with support at four points, and the link 9 above it
A hydraulic cylinder 11 is installed between the machine body 8 on the traveling vehicle side and the hydraulic cylinder 11 is extended and operated to lift the links 9 and 10 when turning in the annex, etc. to perform planting work. It operates to raise the part 3.

On the other hand, a preliminary seedling mounting stand 14 is placed on the body 8 at the rear of the traveling vehicle 1, which corresponds to the position of the rear wheel 12, via a support device 13.
is provided.

In the support device 13, the support stand 15 is assembled to non-parallel four-point support by links 16 to 18, and a hydraulic cylinder is installed between the support stand 15 and the fuselage 8 on the side of the links 17 and 18 arranged behind the support stand 15. 19 is provided, and as the hydraulic cylinder 19 expands and contracts, the links 16 to 18 move so that the support base 15 is tilted rearward from a horizontal state.

In the preliminary seedling mounting table 14, a lower placing table 20 is integrally fixed on a support table 15 with a plurality of pillars 21, and this placing table 20
A thin plate-shaped seedling-taking board 22 on which preliminary seedlings a are placed is placed on top.

The seedling picking board 22 has a stopper 24 at the bottom of the handle 23, so that when it is placed on the mounting stand 20, the stopper 24 hits the front end of the stand 20 and the seedlings can be moved rearward. It has become.

Here, when the support stand 15 is tilted backward by the above-mentioned support device 13, the mounting table 20 is also tilted backward together, but at this time, the upper rear end of the mounting table 20 is just above the seedling stand of the planting section 3. 6 and communicate and connect.

Moreover, an upper stage mounting table 26 is attached above the lower stage mounting table 20 via a link mechanism 25 for lifting and lowering.

These link mechanisms 25 and the mounting table 26 are integrally constructed, and as detailed in FIG. 2, the lower mounting table 20
The lower ends of the vertical links 29 and 30 are pivotally supported by metal fittings 27 and 28 fixed to the front and rear sides, respectively.

The vertical links 29 and 30 are protrusions 29 that protrude upward by bending the upper ends of a pair of vertical shaft portions that extend parallel to the left and right at a distance corresponding to the width of the mounting table 20, respectively, into a substantially inverted U shape. ', 30', and the left and right upper bent portions are integrally connected by horizontal horizontal shaft portions 27'', 30'', and the horizontal horizontal shaft portion 29 of the vertical link 29.30 is
A straight horizontal link 31 is mounted horizontally between the opposing ends of the ", 30", and a substantially U-shaped locking link 32 is attached to the rear vertical link 30, which is the same as the horizontal link 31. It extends horizontally on a plane.

In this way, these links 31 and 32 connect the upper stage 2.
6 is constructed, and a seedling collecting board 3 on which a spare seedling is placed is placed.
3 is placed on the lower stopper 35 of the handle 34 in contact with the horizontal shaft portion 29'' of the vertical link 29, etc., as described above, and the parallel 4 A point-supported link mechanism 25 is constructed.

Furthermore, stoppers 36 are provided in front of the metal fittings 27 and 28, respectively.
．． A return spring 39 is provided between the vertical link 29 and the metal fitting 38.
is installed.

As a result, the vertical links 29.30 are normally raised by the force of the spring 39 and come into contact with the stoppers 36.37, as shown by the solid lines in FIGS. 1 and 3.
The links 31 and 32 of No. 6 are horizontally located above the lower stage 20 at a distance, and the preliminary seedlings and the seedling removal board 33 are placed thereon. In this placed state,
Spare seedlings are attached to the protrusions 29' and 30' of the vertical links 29 and 30.
It is maintained to prevent sideways slipping from side to side.

When replenishing spare seedlings, first, the supporting device 13 operates so that the mounting tables 20 and 26 are turned backward, and at this time, the lower stage 1's mounting table 20 is continuously connected to the seedling mounting table 6 of the planting section 3. That seedling board by connecting it to? Seedlings are replenished by sliding the second spare seedling a onto the seedling mounting stand 6.

Thereafter, when it becomes necessary to replenish the spare seedlings on the upper stage 26, the handle 34 and other parts of the seedling removing plate 33 are manually pushed backward.

Then, the vertical links 29, 30 . collapses against the force of the spring 39, and as shown by the chain line in FIG. 3, the seedling removal plate 33 and the spare seedling tray descend in a horizontal state together with the upper stage 26, and are superimposed on the lower stage 20. I come to do it.

Therefore, in the same way as described above, the support device 13
26 is tilted backward, the rear end of the retaining link 32 substantially coincides with the upper end of the seedling platform 6 of the planting section 3 and becomes continuously connected to the upper end of the seedling tray 33. The upper preliminary seedlings are supplied to the seedling platform 6. In this case, the preliminary seedlings are placed on the protrusions 29' of the vertical links 29, 30.

30', the seedlings slide down to a predetermined position on the seedling stand 6 and are replenished while being guided so as not to slip sideways.

The seedling picking plates 22 and 33 in the above embodiment may be fixed to the lower placing table 20 and the upper placing table 26, respectively (in this case, the side-slipping of the spare seedlings placed thereon) may be used. However, the vertical link 29.30 and the protrusion 29',
30'.

It goes without saying that the preliminary seedling mounting table of the present invention can be applied not only to the riding-type rice transplanter of the above embodiment but also to a walking-type rice transplanter.

As described above, according to the present invention, when configuring the spare seedling mounting table installed in the rice transplanter into multiple upper and lower stages, the upper tier spare seedling holding table is separated upwardly from the lower tier spare seedling holding table by means of a link member. The link member is configured to be movably supported between a multi-tiered state and a seedling replenishment position where the seedling supply position is lowered to near the position height of the lower tier spare seedling mounting platform and communicates with the end of the seedling mounting platform, and the link member is When the upper spare seedling mounting table is supported in the multi-tiered state as described above, it is configured to have projections that protrude upward from both sides of the upper placing table, so that the spare seedlings can be placed on the holding table. In this case, the spare seedlings are prevented from shifting sideways by the upward protrusion of the link member, and there is no need to add a special member for preventing sideways sliding. Replenishment can be carried out accurately, and the upper tier spare seedling table is supported by a link member, and when replenishing seedlings, it is lowered to near the position height of the lower tier spare seedling table and replenishes the seedlings. Since it is possible to do this, it also has the effect of making it easier to supply seedlings.
