Regarding

[0002]

2. Description of the Related Art In the above-mentioned riding type rice transplanter with a fertilizer application, conventionally, as shown in, for example, Japanese Patent Laid-Open No. 3-10612, a fertilizer application apparatus is provided by a support frame erected from a planting transmission case of the seedling planting apparatus. In addition to being fixedly supported, the planting mechanism and the fertilizer feeding mechanism are interlockingly connected via a push-pull rod.

[0003]

In the conventional structure described above, the drive structure in the fertilizer application device for supplying fertilizer to the vicinity of the side of the seedling planting site is as simple as possible, and the fertilizer downflow path is shortened, resulting in clogging of fertilizer. Etc. are less likely to occur and the fertilization work can be performed smoothly. However, in the above conventional structure, since the rear side of the lower end of the seedling stand on which the planting seedlings are placed is covered with the fertilizer application over the entire line, for example, when the planting work in the field is completed. If some seedlings remain on the seedling stand,
The operation of taking out the remaining seedlings was hindered by the fertilizer application, and there was a drawback that the operation of taking out the seedlings was difficult.
The object of the present invention is to eliminate the above-mentioned disadvantages, while making the most of the advantage of the conventional structure, to make it easy to take out the remaining seedlings on the seedling stand, and also to easily perform the fertilizer supply operation. The point is to provide a rice transplanter with a fertilizer application that can improve the work efficiency as a whole.

[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 is a work position located near an upper part of a planting mechanism in the seedling planting apparatus. In the seedling planting device, the fertilizer supply position is located near the upper end of the seedling stand and above the seedling planting device, and is vertically slidably supported by a support rail standing upright from the frame of the seedling planting device. .

[0005]

[Function] When seedling planting work and fertilizer application work is performed in the field, by fixing the fertilizer application to the work position on the lower side, the fertilizer downflow route becomes shorter, and the granular fertilizer is less likely to be clogged in the downflow route. Therefore, it is possible to maintain smooth fertilization work for a long period of time, and it is possible to easily interlock the planting mechanism and the fertilizer feeding mechanism in the seedling planting device with a simple interlocking mechanism. When replenishing fertilizer to the fertilizer storage section of the fertilizer application, by fixing the fertilizer application to the fertilizer supply position near the upper end of the seedling stand, fertilizer can be supplied from the operating section of the riding-type traveling machine body. It becomes possible to supply it, and it is possible to work easily without the trouble of an operator stepping into the mud. Moreover, even when taking out a small amount of placed seedlings left on the seedling stand after the work is completed, if the fertilizer application is set to the fertilizer supply position, the rear outer side of the lower end of the seedling stand is greatly opened. It will be easy to take out the remaining seedlings.

[0006]

[Effects of the Invention] Therefore, although the operation of feeding the fertilizer is simple and can be performed smoothly with less clogging, the work of replenishing the fertilizer and taking out the remaining seedlings on the seedling stand can be performed easily. The overall work efficiency can be improved in the seedling planting work in the paddy field.

Embodiments will be described below with reference to the drawings. Figure 3
Shows a rice transplanter with fertilizer application. In this rice transplanter, a seedling planting device 2 is movably connected to a rear portion of a riding type traveling machine body via a link mechanism 1, and a fertilizer application device 3 is mounted on the rear side thereof. The seedling planting device 2 takes out the seedling stand 5 which reciprocates laterally with a constant stroke with respect to the planted transmission case 4 which also serves as a frame, and the seedlings placed on the seedling stand 5 one by one from the lower end. It is configured to have a plurality of planting mechanisms 6 for planting in a field, a leveling float 7 for leveling a field scene, and the like, and is supplied with power from the traveling machine side through a planting transmission case 4 to allow a plurality of machines to travel while traveling. It is constructed so that the seedling planting work can be performed. As shown in FIG. 1, the planting mechanism 6 is relatively rotated around the horizontal axis on both sides of a rotating case 8 which is rotatably driven around the central horizontal axis at the rear of the planting transmission case 4. The planting claw support cases 9, 9 are freely supported, and the planting claws 10 for taking out seedlings are connected to the respective support cases 9, 9. Then, as the rotary case 8 is rotationally driven, the planting claw support case 9 relatively rotates via a gear mechanism (not shown) provided in the case, and the tip of the planting claw 10 is a substantially elliptical locus in a side view. While drawing, the seedlings are taken out and planted in the field.

The fertilizer applicator 3 is constructed such that the granular fertilizer stored in the upper fertilizer storage hopper 11 is fed out by a predetermined amount by a fertilizer feeding mechanism 12 which is continuously provided under the fertilizer storage hopper 11. The fertilizer 1 is applied to the grooving device 1 near the side of the seedling planting site by the planting mechanism 6.
3 is configured to guide the flow down into the fertilizer ditch formed in the field scene via the flow down pipe 14. The fertilizer feeding mechanism 12 is rotatably provided in the case around a horizontal axis, and a fertilizer feeding roll 15 having a concave portion for entering fertilizer at a predetermined pitch on the outer peripheral surface is rotated in synchronization with the planting operation, The fertilizer is fed downward by a predetermined amount. The drive is performed from the planting mechanism 6 via the push / pull rod 16. That is, as shown also in FIG. 2, the intermediate position of the connecting member 17 that connects the other end sides of the planting claw support cases 9 in the planting mechanism 6 and the drive gear 19 of the roll shaft 18 are provided at two positions on the left and right. Then, the left and right rotation phases are shifted by 90 degrees, and the rod 16
It is pivotally connected. Therefore, as the planting mechanism 6 is driven, the roll shaft 18 rotates in a predetermined direction, and fertilization is performed by a predetermined amount.

Further, as shown in FIG. 6, when the fertilizer storage hopper 11 is replenished with fertilizer from the rear side of the machine, the fertilizer bag F is placed on the rear side of the fertilizer application device 3 so that it can slide freely. A fertilizer table 20 for supporting is provided. The fertilizer placement table 20 is rotatably supported by switching between a vertical placement posture and a horizontal fertilizer supply posture. In the vertical placement posture, the feeding state of the fertilizer feeding mechanism 12 from the outside of the machine is visually checked. The through hole 21 is formed so that it can be formed.

I am doing it. More specifically, as shown in FIGS. 4 and 5, a pair of left and right support rails 22 are fixedly erected from the planted transmission case 4 which also serves as a frame, and each support rail 22 slides through four guide rollers 23. Each fertilizer application device is attached to a freely supported slide frame 24, and a drive gear 26 that engages with a rack gear 25 formed on the support rail 22 is driven by an electric motor M with a reduction mechanism to vertically slide the entire fertilizer application device. It is configured to be possible. When the fertilizer application device 3 moves up from the working position,
Although it is necessary to release the linkage for feeding drive by the rod 16, this rod 16 can be easily separated. That is, as shown in FIG. 7, the rod 16 is divided into upper and lower parts, and the middle part is externally fitted by the cylindrical body 27. It is urged to rotate by a spiral spring 28, and the upper side split rod 16b has a locking pin 29.
