Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rice transplanter with a fertilization device that applies fertilizer to a fertilization groove formed at the same time as planting seedlings.

[Prior art]

In most conventional rice transplanters with fertilization devices, seedlings are planted inside the groove provided in the fertilization device. The side plate on the side closer to the seedlings was shorter than the rear end of the side plate on the side farther from the planted seedlings.

[Problem that the invention attempts to solve]

Therefore, there was a drawback that the pressure of the mud displaced by the trench section pushed the adjacent planted seedlings, causing the seedling posture of the already planted seedlings to be tilted. In addition, in the case of a walk-behind rice transplanter, when the worker walks between parallel rows of seedlings, the pressure of the mud displaced by the feet is applied to the planted seedlings on both sides, causing the seedlings to grow. The drawback was that it disturbed the planting posture.

Furthermore, because the side plate on the side closer to the planted seedlings is shorter than the rear edge of the side plate on the side far from the planted seedlings, muddy water near the seedlings flows into the trench, which can affect the posture of the seedlings immediately after planting. It had the disadvantage of causing confusion.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a rice transplanter with a fertilization device that can eliminate the above-mentioned conventional drawbacks and form a fertilization groove without disturbing the planting posture of seedlings.

[Means to solve the problem]

A rice transplanter with a fertilization device according to the present invention that achieves the above object is a rice transplanter with a fertilization device that applies fertilizer to a fertilization groove formed at the same time as planting seedlings. A groove section for forming a fertilization groove is provided at a side row position close to the line of the row, and of the left and right side plates forming the groove section, the side plate closest to the planted seedlings is placed parallel to the direction of movement of the machine. It is provided and extends further rearward than the rear end of the side plate on the side farthest from the planted seedlings.

[Effect]

Even if the groove section 10 is provided between the rows of the planted seedling rows and at the side row position close to the line of the planted seedling rows, the side plate 13 closest to the planted seedlings among the both side plates is Groove section 10 is provided parallel to the traveling direction.
It is possible to prevent the seedling posture of adjacent already planted seedlings from being disturbed by mud pushing. In addition, fertilization groove 1 immediately after furrowing
7 can be blocked by the long side plate 13 located near the planted seedlings 15 and allowed to flow in from the short side plate 14 located far from the planted seedlings 15, so the posture of the seedlings immediately after planting is The fertilization groove 17 can be closed after fertilization without disturbing it. In addition, in the case of a walk-behind rice transplanter as in the embodiment, the mud pushing caused by the feet of the worker due to walking is buffered by the fertilization groove 17, so that the planted seedlings 15 located outside the fertilization groove 17
It can prevent the seedling posture from being disturbed immediately after planting.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings as an embodiment thereof.

Figure 1 is a side view of a rice transplanter with a fertilization device;
2 is an engine provided at the front of the aircraft, 2 is a float provided at the bottom of the aircraft, and 3 is a running wheel. A seedling stand 4 is installed diagonally at the rear of the machine, and a planting rod 5 is provided at the lower end of the table, so that a predetermined amount of seedlings can be scraped and planted in the field. 6,6
are handles located on both sides of the rear of the aircraft. A fertilizer tank 7 is provided below the handle 6.
The granular fertilizer in the fertilizer tank 7 is intermittently or continuously discharged toward the field from a nozzle 9 via a discharge device 8 such as a rotary valve. A groove section 10 of the fertilization device is provided from the rear end of the float 2 to the lower part of the nozzle 9.

FIGS. 2 and 3 are a plan view and a side view showing details of the groove forming section 10 described above. This second
As shown in the figure and FIG. 3, the groove-making section 10 is provided at the rear of the float 2, and is provided at a side row position between the rows of planted seedlings and close to the line of the planted seedling rows. The planted seedlings 15 are arranged so as to be planted outside the groove section 10, and include a front groove cutting board 11, a rear groove cutting board 12, a side plate 13 near the planted seedlings 15, and a planted seedling. 15 and a side plate 14 on the far side. The front groove plate 11 is fixed to the float 2 with bolts, and the rear groove plate 12 is further fixed to this groove plate 11 with bolts.

This rear grooved plate 12 can be rotated arbitrarily around this bolt 16 by loosening a bolt 16.If the lower end of the grooved plate 12 is fixed at an appropriate position, The depth of the groove cut can be adjusted. The side plates 13 and 14 are fixed to the rear end of the rear grooved plate 12 with a predetermined space interposed therebetween. This side plate 1
3 and 14, the side plate 13 on the side closer to the planted seedlings 15
The side plate 14 on the side far from the planted seedlings 15 is inclined to spread backward, and the side plate 14 on the side close to the planted seedlings 15 is provided parallel to the traveling direction of the aircraft along the row of planted seedlings 15. The side plate 13 extends rearward longer than the rear end of the side plate 14 on the side farthest from the planted seedlings 15.

When the above-mentioned rice transplanter is run in a field, seedlings 15 are planted in parallel rows on both sides of the rice transplanter as shown in FIGS. , parallel fertilization grooves 17 are formed between the rows of the planted seedling rows at side row positions adjacent to the line of the planted seedling rows. The fertilizing groove 17 is the groove making section 10
The side plates 13 and 14 forming the fertilizing groove 17 prevent the fertilizing groove 17 from collapsing and muddy water from entering the fertilizing groove 17, and in this state, the granular fertilizer 1 from the nozzle 9 is
8 is applied to the bottom of the fertilization groove 17 intermittently or continuously. The side plate 13 on the side of the trench section 10 near the planted seedlings 15 is parallel to the row of planted seedlings, so the planted seedlings 15
There is no need to press the mud toward the soil, and the planting posture of the seedlings is not affected. In addition, since the side plate 14 on the side far from the planted seedlings 15 is inclined to widen rearward, muddy water can be guided away from the planted seedlings 15 while promoting the formation of a wide fertilization groove 17, and it can also prevent the movement of the machine from moving. Resistance can be reduced. Furthermore, even if the side plates 13 and 14 become clogged with mud when the machine moves backward, the mud is easily peeled off due to the slope of the side plates 14 when the machine moves forward again, so that it does not interfere with groove-cutting.

In addition, since the groove-cutting section 10 is arranged at a side row position close to the line of the planted seedling row between the rows of the planted seedling rows, the adjacent already planted seedlings will not be affected by mud pushing. In addition, by locating the planted seedlings 15 outside the formed fertilization groove 17, the planted seedlings 15 immediately after planting are not affected by mud pushing caused by the walking of the worker. There is an advantage. That is, as shown in Fig. 4, when the worker walks along the rear of the rice transplanter, the mud around the position 19 where the worker steps is pushed outward in the direction of the arrow, but the fertilization groove By locating the planted seedlings 15 outside of the soil 17, the pressure of this mud is buffered and does not affect the planted seedlings 15.

Furthermore, among the side plates 13 and 14 provided on the left and right, the side plate 13 on the side closer to the planted seedlings 15 is
5 is longer than the rear end of the side plate 14 on the far side, so when the field is soft, the flow of mud into the fertilization groove 17 immediately after trenching is prevented by the side plate 13 on the long side plate 13 side. , and the mud located on the side of the short side plate 14 flows into the fertilizing groove 17 as shown by the arrow, so that the seedling posture of the planted seedlings 15 immediately after planting is not disturbed, and the mud located on the side of the short side plate 14 is prevented from flowing into the fertilizing groove 17. The fertilization groove 17 can be closed. Therefore, if the side plate on the side closer to the planted seedlings is shorter than the rear edge of the side plate on the side far from the planted seedlings, as in the past, the mud near the planted seedlings will flow into the fertilization groove, and as a result of the reduction of the mud. This eliminates the drawback that the planted seedlings are tilted and the seedling posture is disturbed.

[Effect of idea]

In short, the rice transplanter with a fertilization device according to the present invention is a rice transplanter with a fertilization device that applies fertilizer to a fertilization groove formed at the same time as planting seedlings. A groove section for forming fertilization grooves is provided at a side row position close to the line, and of the left and right side plates that make up the groove section, the side plate on the side closer to the planted seedlings is placed parallel to the row direction of the machine and for planting. Because it extends backwards longer than the rear end of the side plate on the side far from the seedlings,
Even if the groove section is provided between the rows of the planted seedling rows and at the side row position close to the line of the planted seedling rows, the side plate closest to the planted seedlings among the side plates should be aligned with the direction of movement of the aircraft. By arranging them parallel to each other, the seedling posture of adjacent already planted seedlings will not be disturbed by mud pushing from the trench cutting section, yet the flow of mud into the fertilizing trench immediately after trench trenching can be positioned close to the planted seedlings. By blocking the fertilization with a long side plate and letting it flow from the side of the short side plate located far from the planted seedlings, it is possible to close the fertilization groove after fertilization without disturbing the posture of the seedlings immediately after planting, unlike conventional methods. It is possible to prevent the mud near the planted seedlings immediately after planting from flowing toward the trench section, and the planted seedlings from tilting due to the reduction in mud. In addition, in the case of a walking-type rice transplanter as in the example, the planted seedlings are not disturbed by mud pushing caused by the feet of the worker when they are walking, and a stable planting posture is maintained at all times. Fertilization can be done while maintaining the soil.
