【Example】

 An embodiment of the present invention will be described below. 1 and 2 are a plan view and a side view of a rice transplanter, in which a driver's seat 4 is located in the center of a machine body 3 having front wheels 1 and rear wheels 2, and a main gear shift operation lever 6 and an auxiliary gear shift operation lever are provided on the left and right sides thereof. 5 is provided. As shown in FIG. 3, the main shift operation lever 6 is operated to switch between road traveling, planting traveling (forward), reverse traveling, and seedling splicing. By operating the auxiliary shift operation lever 5, switching between high speed and low speed, and raising / lowering of the left and right markers and the planting part are performed. Further, there is a steering wheel 7 and a hood 8 in front of the driver's seat 4, and there are front spare seedling mounts 9 and 9 and rear spare seedling mounts 10 and 10 to the left and right of the machine body 3. The rear spare seedling mounts 10 1 and 10 2 are rotatably mounted on rotating shafts 11 and 11 arranged outside the main gear shift operating lever 6 and the sub gear shift operating lever 5. At the rear of the machine body 1, there is a planting section 12, 13 is a seedling stand, and a planting device 14 and a float 15 are mounted below the seedling stand 13. Then, the seedling mats are stacked on the preliminary seedling mounts 9 and 10 and the seedling mounts 13, and the seedlings are planted in the planting section 12 while the machine body 3 is running in the field. When the seedling mat of the seedling placing table 13 is insufficient, the rear preliminary seedling placing table 10 is rotated backward around the rotation axis 11 as shown by the chain line 10 'in FIG. The seedling mats loaded on the rear spare seedling mounting table 10 are sequentially transferred to the seedling mounting table 13, the machine body 3 is run again, and the planting section 12 carries out planting work.

Here, as shown in FIG. 5, when the rotary shaft 11 of the spare seedling stand 10 is arranged inside the main gear shift operation lever 6 and the sub gear shift operation lever 5, During the planting work, the spare seedling mount 10 will be located right above the main gear shift operation lever 6 and the sub gear shift operation lever 5, so the operator should put his or her hand under the spare seedling mount 10 in a narrow space. There is a problem that it is difficult to operate the lever because the main gear shift operation lever 6 and the sub gear shift operation lever 5 must be operated. However, in the rice transplanter of the present invention, by disposing the rotating shaft 11 on the outside of the main gear shift operation lever 6 and the sub gear shift operation lever 5, the rear auxiliary seedling stand 10 is placed in the driver's seat 4 at the time of planting work. When positioned on both the left and right sides, the space directly above the main gear shift operation lever 6 and the sub gear shift operation lever 5 is configured. Therefore, the spare seedling stand 10 does not get in the way, the operator can easily operate the lever, and the planting work is easy, which is convenient.

A lock mechanism 20 made of a magnet is provided at the front end of the rear spare seedling stand 10, and when the rear spare seedling stand 10 is rotated to the left and right sides of the driver's seat 4, the lock mechanism 20 moves forward. The rear end of the spare seedling stand 9 is attracted by a magnetic force to fix the spare seedling mounts 9 and 10 to each other, and the rear spare seedling mount 10 does not rotate carelessly. By providing the lock mechanism 20 in this way, it is possible to prevent the seedling mat from collapsing or falling by pressing the vibration or backlash of the rear preliminary seedling mounting table 10 during the planting work, and the front preliminary seedling mounting table 9 to the rear preliminary seedling mounting table 9 can be prevented. It is convenient because the seedling mat can be supplied to the stand 10 smoothly. When the rear preliminary seedling placing table 10 is rotated backward as shown by the one-dot chain line 10 ′ in FIG. 1, some rotation is allowed without providing such a locking mechanism. If you leave it, there is an advantage that it is easy to align the rows when splicing.

Further, as shown in FIG. 2, the front preliminary seedling placing table 9 and the rear preliminary seedling placing table 10 are divided by front and rear plates 21, 22 and 23, 24, respectively, and these plates 21, 22, and By connecting 23 and 24 with hinges 25 and 26, respectively, the plate 22 of the front preliminary seedling mounting table 9 and the plate 23 of the rear preliminary seedling mounting table 10 are moved to the positions shown by the alternate long and short dash lines 22 'and 23' in the figure. It has a structure that can be folded. When the front spare seedling placing table 9 and the rear spare seedling placing table 10 do not have seedling mats in this manner, the plates 22 and 23 are folded so that the operator can get on and off the operating seat 4. It is convenient and convenient. If the plate 22 of the front preliminary seedling mounting table 9 is given a considerable weight, the balance weight can be moved forward by folding the plate 22 forward, so that the head up of the rice transplanter is increased. Can be prevented and the front and rear can be balanced. Further, as shown in FIG. 6, when the preliminary seedling placing table 9 has a multi-tiered structure, the seedling mats from the lower preliminary seedling placing table 27 are set by folding the plate 22 to the 22 'position. There is also an advantage that it is easy to take out. In addition, when the preliminary seedling placing table is configured to be foldable as described above, as shown in FIG. 2, when the column 28 of the front preliminary seedling placing table 9 is positioned in front of the rear end of the bonnet 8, When the plate 22 is folded, the front spare seedling stand 9 does not protrude from the rear end of the hood 8, which is convenient for getting on and off the driver's seat 4.

Further, as shown in FIG. 7, when the preliminary seedling placing table 10 is provided at a height lower than the backrest of the driver's seat 4, when the preliminary seedling placing table 10 is rotated to the seedling splicing position. Since the spare seedling stand 10 wraps around the rear of the driver's seat 4, the total length L1 of the rice transplanter must be increased, and the overhang amount L2 also increases, making it difficult to balance the front and rear of the machine. There is a drawback. Therefore, as shown in FIG. 8, if the spare seedling mounting table 10 is provided at a position higher than the backrest of the driver's seat 4 so that the spare seedling mounting base 10 and the driver's seat 4 do not interfere with each other, the spare seedling mounting base 10 is rotated to the seedling joint position. In this case, the spare seedling stand 10 can be brought above the driver's seat 4, so that the total length L1 'of the rice transplanter can be shortened, and the overhang amount L2' can be reduced to make the machine compact. It is possible to balance it easily. Further, when the lengths of the machines are the same (L1 '= L1), there is an advantage that the length L3' of the seedling mounting table 13 can be made longer than the length L3 of the seedling mounting table 13 of FIG.
