Description

[Detailed explanation of the idea] The present invention relates to a seedling mounting device in a rice transplanter.

That is, each seedling mounting surface on which the seedling pine is placed can be moved vertically, so that planting can be stopped for each desired row.
For example, when changing the number of planting rows during ridge treatment, planting can be stopped as appropriate, and the structure is simple and easy to manufacture without requiring a conventional planting clutch. It is provided so that it can be operated well and carried out suitably.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the combine harvester, in which swing-type transmission cases 10 with wheels 9 mounted on the shafts are installed on both sides of the rear of the engine E mounted above the front part of the long float 8 in the longitudinal direction. A handle 12 extends upward from the attached case 11, a planting depth adjustment lever 13 is interposed between the planting case 11 and the rear of the float 8, and a notch of the seedling take-out plate 2 installed horizontally at the rear. A planting claw 1 (not shown) that moves along a predetermined trajectory X is installed so as to scrape block seedlings from a seedling pine A and plant them on the rice field, and is constructed in the same manner as in the conventional trench structure.

A plurality of supporting frames 4 are lined up and extending obliquely from the seedling take-out plate 2 above the handle 12 side, and horizontally installed connecting frames 13, 13 straddle the lower surface of each supporting frame 4.
a, 13b, all the supporting frames 4 are integrally connected, and grooves 14 are formed over the entire length on the lower inner surfaces of both supporting frames 4 on both sides, and grooves 14 are formed on both lower side surfaces of each intermediate supporting frame 4. The fitting frame 1 forms grooves 14 over the entire length and spans the lower part of the entire support frame 4.
5 is slidably fitted to the rear lower rail 2a of the seedling take-out plate 2, and each support frame 4 is installed so that it can be reciprocated in the lateral direction by the same drive device (not shown) as the conventional type. and configure.

3 is a seedling mounting board on which the seedling pine A is placed, and the both sides of each seedling mounting board 3 are connected to the grooves 14, 1 of the adjacent support frames 4, 4.
4, and is fitted so that the lower end 3a of each seedling loading plate 3 can approach or move away from the seedling take-out plate 2, and the lower surface of the upper end side of each seedling loading plate 3. , fix the support frame plate 16 with screws 17, and insert the grip lever 5 from the support frame plate 16 toward the rear lower part.
Configure by extending.

In addition, a narrow elongated hole 18 is provided on the lower side of each seedling board 3.
A support plate 19 is drilled and hung below the seedling board 3.
The lower part of the rotating arm 20 is pivotally supported via a support shaft 21, and the elongated hole 18 is inserted from the lower part of the rotating arm 20.
A locking hook 6 having a pointed end 6a and bent in an L shape is integrally extended toward the rotating arm 2.
An operating rod 7 connected to the upper part of the seedling plate 3 extends so as to fit into the support frame plate 16, and a grip portion 7a is bent at the rear end of the operating rod 7. It is arranged so as to be located near the gripping rod 5.

Therefore, if each seedling loading board 3 is lowered so that its lower end 3a is closest to the seedling taking out board 2,
The lower end side of the seedling pine placed on the seedling mounting plate 3 faces the seedling take-out plate 2, and the planting claw 1 moving along the trajectory X scrapes the block seedlings and performs planting. become.

In addition, when changing the number of planting rows when performing ridge treatment etc., hold the grip lever 5 above the seedling board 3 at the part where planting is to be stopped, and also press the operating lever 7.
When you grasp the grip part 7a and pull it towards the grip rod 5 side,
As the rotating arm 20 rotates, the locking hook 6 rotates and sticks into the bottom side of the seedling pine A through the long hole 18, and from this state, it is pulled upward by holding the gripping rod 5 and the gripping portion 7a. Then, as shown in Fig. 6, as the seedling plate 3 rises, the seedling pine A is pulled up and the lower part of the seedling pine A comes off the trajectory X of the planting claw 1, so planting in this area is stopped. This means that you will be able to do so.

When planting again, if the seedling mounting board 3 is pushed down by the reverse operation described above, it will come within the locus X of the planting claw 1 and planting will be performed.

In this way, in the present invention, each seedling loading board 3, which extends diagonally upward from the seedling taking out board 2 through which the planting claw 1 looks, is attached to the support frames 4, 4 on both sides, which can be moved together only in the lateral direction. It is fitted so that it can slide freely in the vertical direction, and a grip rod 5 is installed on the upper end side of each seedling mounting plate 3, and the seedling pine A is moved in and out from the lower side of each seedling mounting plate 3 on the upper surface. A locking hook 6 installed on each seedling mounting plate 3 is connected to an operating rod 7 extending to the vicinity of the grip rod 5 so that the seedling pine A can be placed on the locking hook 6. By locking the seedling pine A with the locking hook 6 and moving the planting plate 3 upward, planting can be stopped for each desired row, which is a simple method without requiring a planting clutch unlike the conventional method. The structure is easy to manufacture,
It has the feature that it can be operated reliably and satisfactorily while looking at it, and can be carried out suitably.
