[Problems to be Solved by Prior Art and Invention] In general, this seedling type seedling planting machine is provided with an auxiliary seedling placing table for placing the planted seedlings to be fed to the seedling placing table of the seedling planting section. There is. By the way, it is common to supply seedlings from the auxiliary seedling mount to the seedling mount by raising the seedling planting section. Therefore, the height of the auxiliary seedling mount is set according to the raised seedling mount. Is preferable from the viewpoint of workability. However, when doing so, during the seedling planting work, there is a problem that the auxiliary seedling mounting base is too high to block the rear view and impair the body balance. Therefore, there is an attempt to vertically move the auxiliary seedling mounting table via a parallel link mechanism and to move the auxiliary seedling mounting table up and down in a linked manner.

By the way, when the auxiliary seedling stand is configured to move up and down in this way, if the swing support shaft portion of the base end of the parallel link mechanism is exposed as it is, the link arm and the link arm will not move when the parallel link mechanism swings up and down. There is a fear that it will be caught between the aircraft side bracket and being caught, and in order to avoid this there is a special safety cover, but it is unacceptable to increase the number of parts and it is a safety cover. It is possible to forget to put on, and it is necessary to further improve.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised with the object of providing an auxiliary seedling stand device for a riding type seedling planting machine that can eliminate these drawbacks. The auxiliary seedling mounting table for mounting the seedling seeding table-supplying planting seedlings is assembled to the traveling machine body in which the seedling planting section provided with the seedling mounting table is vertically movable. The base is swingably supported by an auxiliary seedling table mounting bracket provided on the machine side, and is supported via a parallel link mechanism that moves up and down in linkage with the vertical movement mechanism of the seedling planting section. Then, the auxiliary seedling mounting table is constructed so that it rises following the rising of the seedling planting portion, and the auxiliary auxiliary seedling mounting table is further detachably mounted to the base end of the parallel link mechanism. Characterized by the structure that covers the side support shaft from the side It is assumed that.

With this configuration, the present invention covers the rotation fulcrum portion of the link mechanism from the side surface by using the auxiliary auxiliary seedling stand.

The frame member 10 is integrally fixed to the side, and a bracket 10a for attaching the auxiliary seedling stand, which is substantially U-shaped in a plan view, is integrally formed on the upper end portion of the frame member 10. In this bracket 10a, the link arm 11a of the parallel link mechanism 11,
A base end of 11b is pivotally supported by a support shaft 12 so as to be vertically swingable. In addition, the support shaft 12 is configured so as to be retained by a retaining pin 12a. Reference numeral 13 is an auxiliary seedling table, and a supporting arm 13a is vertically provided at the bottom of the auxiliary seedling table 13, and the tip ends of the link arms 11a and 11b have a spindle 11c on the supporting arm 13a. It is rotatably supported by a shaft. Further, the upper end of the operating arm 14 is attached to the lower link arm 11b by the support shaft 14a.
The lower end portion of the operating arm 14 is pivotally supported via a support shaft 14b at the tip of an auxiliary arm 15 whose base end is pivotally supported at the machine body frame 1a. It is swingably supported. The auxiliary arm 15 has a working plate 15a formed in the left-right direction.
Are arranged above the lower link 2a of the lifting link mechanism 2 so as to face each other. Then, in the process of raising the seedling planting part 3 which is descending to the working posture, the lower link 2a
Comes into contact with the operating plate 15a and lifts it up, which causes the auxiliary arm 15 to move upward, pushing up the parallel link mechanism 11 via the operating arm 14, and thus the auxiliary seedling stand
13 can be moved up following the seedling planting section 3 and set to a seedling replenishment position slightly higher than the seedling placing table 4, whereby the operator can plant the planted seedlings placed on the auxiliary seedling placing table 13. Can be supplied to the seedling mounting table 4. The seedlings and the frame material 10 are provided with stoppers 10b. The stoppers 10b contact the lower link arms 11b as the parallel link mechanism 11 moves downward, and further downward movement is restricted to assist. The lower limit of the seedling stand 13 is determined.

Reference numeral 16 denotes a spare auxiliary seedling mounting table provided separately from the auxiliary seedling mounting table, and the spare auxiliary seedling mounting table 16 is arranged on both left and right sides of the driver's seat 8. That is, the auxiliary auxiliary seedling stand
No. 16 is one that can be planted seedlings in two stages,
The base frame 16a is integrally fixed to the support bracket 16b. Furthermore, this support bracket 16b has a mounting hole 1
6c is bored, and the support shaft 12 is used for the bracket 10
It is configured so that it can be detachably attached to a from the side, and these auxiliary auxiliary seedling mounts 16 allow the parallel link mechanism 13
It has a structure that can cover the support shaft part from the side.
Incidentally, 16d is a handle protruding from the support bracket 16b.

By the way, the planted seedlings are scraped from the seedling box by the scraper 17 and placed on the scraper 17 as they are, and the scraper 17 is configured to be placed on the auxiliary seedling mounting table 13 and the auxiliary auxiliary seedling mounting table 16. ing. Further, it is considered that the empty scraper 17 after the planted seedlings are supplied is stored in the scraper storage case 18.

In the embodiment of the present invention configured as described above, in the planting work posture in which the seedling planting section 3 is lowered as described above, the auxiliary seedling stand 13 is in the lowered position, so that the rear view of the operator is It is not blocked by the auxiliary seedling stand 13. When the seedling planting section 3 is raised to supply the planting seedlings to the seedling placing table 4, the auxiliary seedling placing table 13 also rises following this, and thus the seedling replenishing work raises the seedling placing height. It can be easily performed according to the height of the table 4.

Thus, in the present invention, the auxiliary seedling stand 13 is connected to the parallel link mechanism.
Although it can be moved up and down by using 11, the support shaft of the parallel link mechanism 11 on the base end side is protected from the side surface by the auxiliary auxiliary seedling mounting table 16, and thus the conventional seedling supply is possible. There is no need to provide a separate safety cover to protect workers when doing so. Moreover, this preliminary auxiliary seedling mounting table 16 has a parallel link mechanism 11
Since it is configured to be detachably attached to the bracket 10a that supports the base end of the auxiliary shaft 12 by the support shaft 12, the auxiliary auxiliary seedling mounting table 16 can be removed and used as a tool for carrying the planted seedlings to the machine body. It is convenient and convenient. Incidentally, in the embodiment, the support shaft 12 is configured to be pulled out to the outside, and accordingly, in order to remove the auxiliary auxiliary seedling stand 16 which is also attached to the outside,
Although it is necessary to remove the support shaft 12, in this case, when the support shaft 12 is removed to remove either the left or right auxiliary auxiliary seedling mounting table 16, the link arms 11a and 11b on the side are disengaged from the bracket 10a. In this case, the parallel link mechanism 11 has the opposite side pivotally supported by the bracket 10a via the support shaft 12,
Since the lower link arm 11b is supported by the stopper 10b, there is no problem, and if the support shafts 12 are removed one by one, there is no problem.

Further, in this structure, since the auxiliary auxiliary seedling placing table 16 can be attached and detached by using the support shaft 12 of the parallel link mechanism 11, there is an advantage that parts can be commonly used.

In addition, in the embodiment, when the seedling planting unit 3 is, for example, a model for eight-row planting, the auxiliary seedling mounting table 13 mounts eight-row planting seedlings and four-row preliminary planting seedlings, that is, 12-row planting seedlings for convenience. If you configure it so that it can be placed, and on the left and right auxiliary auxiliary seedling placement table 16, two rows of planted seedlings for four rows are placed, for a total of 16 rows of planted seedlings. Since it can be supplied twice, the workability can be greatly improved, but if all of these 16 planting seedlings are to be mounted on the auxiliary seedling mounting table 13,
This is long in the left-right direction, and it greatly protrudes from the aircraft, and the auxiliary seedling stand 13 also becomes heavy and the load to raise is also large, but as in the example, a part is fixedly mounted on the aircraft side. Distributing the auxiliary seedling placement table 13 in such a way that it has an advantage that the lateral length of the auxiliary seedling placing table 13 can be shortened and the load for raising it can be reduced.

In addition, the support bracket 16b of the auxiliary auxiliary seedling stand 16 of the embodiment
There are four mounting holes 16c in the, and it does not correspond to the number (two) of the support shafts 12, but this is because the mounting position is adjusted back and forth or the left and right auxiliary auxiliary seedling stand 16 The advantage is that they can be configured the same.

Incidentally, the present invention is the auxiliary auxiliary seedling mount described in the above embodiment.
The 16 is designed to be attached from the outside of the machine,
The second embodiment shown in FIGS. 10A and 10B may be mounted from the inside of the machine body. In this case, the auxiliary seedling stand 16 needs to be attached and detached while being moved inward,
Therefore, it goes without saying that it is necessary to provide a gap Y between the outer surface of the bracket 10a and the inner surface of the auxiliary auxiliary seedling stand 16 that is larger than the stroke X for allowing the support bracket 16b to come out of the support shaft 12.

[Operation and Effect] In short, since the present invention is configured as described above, when supplying planting seedlings to the seedling placing table of the seedling planting section, the auxiliary seedling placing stand follows the rise of the seedling planting section. The workability of seedling supply work is improved by raising the
The auxiliary seedling stand can be set at a low position, which does not hinder the rear view and the body balance can be improved, but the base end of the parallel link mechanism for moving the auxiliary seedling stand up and down. The bracket portion for attaching the auxiliary seedling table, which pivotally supports, is covered from the side surface by attaching the auxiliary auxiliary seedling table. As a result, the auxiliary auxiliary seedling mounting table also serves as a safety cover for the site, and the parts can be commonly used.

Moreover, by providing the auxiliary auxiliary seedling placing table, the placement amount of the planted seedlings can be increased without increasing the lateral length and the weight of the auxiliary seedling placing table, and the workability can be improved.

Moreover, the auxiliary seedling mounting table has an advantage that it can be used as a tool for carrying planted seedlings to the machine by removing it from the bracket for mounting the auxiliary seedling mounting table.
