Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts a fertilizer application device above a planting mechanism for taking out seedlings from the lower end of a seedling stand in a planting device and is linked to the planting mechanism. The present invention relates to a rice transplanter with a fertilizer application configured to rotate a fertilizer delivery roll in a fertilizer application via a rotating body for feeding the fertilizer.

[0002]

2. Description of the Related Art In the rice transplanter with the above fertilizer application, conventionally, the fertilizer application is arranged in a fixed position by a supporting frame erected from a planting transmission case.
In addition, the rotating roll for feeding fertilizer forms a concave portion at a constant pitch on the outer peripheral surface into which a fixed amount of fertilizer enters, and is linked with the planting mechanism via a rod to rotate by a predetermined amount. It was constructed so that the fertilizer could be fed out quantitatively.

[0003]

In the above-mentioned conventional structure, since the tall fertilizer application device is present on the rear upper side of the seedling stand over almost the entire planting width, the planting work is completed in a certain field, for example. There is a drawback that this fertilizer application becomes a hindrance when it takes out the placed seedlings that are a little left on the seedling stand later, which makes it difficult to perform the work. The fertilizer remained inside, and the planting mechanism had to be run idle to rotate the feeding roll to discharge the remaining fertilizer, which was a troublesome task. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic configuration of the present invention, in the rice transplanter with a fertilizer application described at the beginning, the fertilizer application work on the lower side is performed on a support rail erected from a frame of the seedling planter. A guide member for supporting the position of the fertilizer application so that the vertical position can be freely changed between the position and the position retracted upward, and rolling the rotary body with the movement when the fertilizer application moves from the working position to the upper retracted position. There is a point to be prepared.

[0005]

[Function] If the fertilizer application is set to the working position on the lower side, the downflow route between the fed fertilizer and the field scene where the fertilizer is supplied is shortened, so that the fertilizer can be smoothly fertilized without causing clogging. If you can take out the placed seedlings that are a little left on the seedling stand after the work is completed, you can relocate the fertilizer application to the upper retracted position, and the outside of the lower part of the seedling stand will be greatly opened, and you can take out the seedlings. Can be done easily. Moreover, as the fertilizer applicator moves upward, the fertilizer feeding rotary member is rolled by the guide member, so that the fertilizer applicator moves and the remaining fertilizer in the feeding mechanism is discharged outward.

[0006]

[Effects of the Invention] Therefore, it is possible to perform a smooth fertilization work in which fertilizer clogging does not easily occur during seedling planting work, but the removal of the remaining seedlings on the seedling stand after the work interferes with the tall fertilizer application device. It can be easily done without being
Moreover, the residual fertilizer can be discharged at the same time as the fertilizer applying device is retreated, and a rice transplanter capable of efficiently performing maintenance work after planting work can be provided.

Embodiments will be described below with reference to the drawings. Figure 1
Shows the rear part of the riding type rice transplanter with fertilizer application. This rice transplanter is configured by connecting a seedling planting device 1 to a rear portion of a riding type traveling machine body (not shown) through a link mechanism, and mounting a fertilizer application device 2 on the upper rear portion thereof. Seedling planting device 1
Is a seedling stand 4 that reciprocally moves laterally with a constant stroke with respect to the planting case 3 that also serves as a frame, a planting mechanism 5 that takes out each seedling from the lower end of the seedling stand 4, and plants it. The fertilizer applicator 2 includes a feeding mechanism 8 for feeding a predetermined amount of fertilizer below the upper fertilizer storage hopper 7, and the fertilizer fed from the feeding mechanism 8 flows down the pipe. It is configured so as to guide the flow down to the grooving device 10 that creates a fertilization groove in the field scene via 9. The planting mechanism 5 rotatably supports a pawl support case 13 having planting claws 12 attached to both side ends of a rotating case 11 which is rotationally driven around a horizontal axis, and is supported by a cam mechanism (not shown). 12 is constructed so that seedlings can be planted by drawing an elliptical locus in a side view.

In the fertilizer feeding mechanism 8, a feeding roll 15 is rotationally driven via a rod 14 pivotally connected to a middle portion of a connecting plate 40 that is erected and connected across the support shafts of the claw support cases 13. The fertilizer is fed out in a predetermined amount according to the planting operation. More specifically, FIG.
As shown in FIGS. 5 and 6, a large-diameter gear 23 is attached to the drive shaft 22 on which the pay-out roll 15 is integrally rotatably fitted, and a small-diameter gear 24 (an example of a rotating body) that meshes with the gear 23 is attached. An arm 26 fixed to the rotary support shaft 25 and fixed to the rotary support shaft 25 and a midway portion of the rotary case 11 are pivotally connected via a rod 14. The arms 26 are provided at two places on the left and right sides, and the pivot points of the arms 26, 26 and the left and right rotating cases 11 are out of phase with each other by about 90 degrees. Therefore, the rotary support shaft 25 is rotated in the same direction as the rotary case 11 is driven to rotate, and the feeding roll 15 is rotated by a predetermined pitch by gear engagement.

The fertilizer applicator 2 is located just above the planting mechanism 5 and is in a lower working position (see FIGS. 1 and 3) overlapping the lower end of the seedling stand 4 (see FIGS. 1 and 3) and holds the placed seedlings during the planting work. The seedling pressing rod 39 is retracted to the outside and is provided so as to be vertically slidable over an upper retracted position [see FIGS. 2 and 4] where the lower end of the seedling stand 4 is opened (see FIGS. 2 and 4). The remaining seedlings on the placing table 4 can be easily taken out. More specifically, the guide rollers 17 are attached to the pair of left and right vertical frames 16 standing from the planting case 3.
The fertilizer application device 2 is supported on the horizontal frame 18 which is slidably supported via the vertical arm 38, and the drive shaft 22 and the rotary support shaft 25 are rotatably supported by the pair of left and right brackets 27, 27. I am doing it.
