Description

[Detailed Description of the Invention] The present invention relates to a fertilization nozzle attachment device in a fertilization rice transplanter.

According to conventional fertilizing rice transplanters, the fertilizing nozzle is generally attached using a bracket at the rear support point of the float, so the position where the fertilizing nozzle is immersed in the soil of the rice field is suitable for planting seedlings using a planting rod. It was further back than its position. However, since the fertilizing nozzle forces the soil downward along with the straw on the soil at the part where it penetrates into the soil, the pressure from the soil and straw that is forced into the soil can be applied to the plants that have already been planted in front. This affected the seedlings, causing them to move or fall.

In addition, the above-mentioned disadvantages can be solved if the fertilizer dispensing nozzle is installed in front of the planting position, but the fertilizer discharging end of the fertilizing nozzle fluctuates in the vertical direction due to the tilting of the float.
If the depth of fertilization was changed unnecessarily or if the machine meandered, the fertilizer would directly reach the planted seedlings, causing growth problems.

The purpose of this invention is to eliminate the drawbacks of the conventional fertilizing rice transplanter mentioned above, and to prevent the planting posture of planted seedlings from being disturbed by fertilization, or growth problems caused by misalignment of the fertilizing position. An object of the present invention is to provide a fertilization nozzle attachment device for a fertilization rice transplanter.

The fertilizing nozzle attachment device of the fertilizing rice transplanter of the present invention that achieves the above purpose sets the position of the fertilizing nozzle attached to the float to enter the soil at a position forward of the seedling planting position by the planting rod, and at the same time The present invention is characterized in that a fertilizer discharge end that extends to and opens toward the bottom near the swinging support point of the float is exposed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to embodiments shown in the drawings.

The figure shows a riding-type rice transplanter equipped with a fertilization device. 1 is the rice transplanter main body, wheels 2 and 3 are provided at the front and rear, and a planting part 5 is pulled through an arm 4 at the rear of the machine. It is connected like this.
The planting section 5 can be vertically moved alternately between the planting position shown in the figure and the raised position shown in the figure by operating the arm 4 using hydraulic pressure or the like.

A driver's seat 6 is provided in the center of the rice transplanter main body 1, and fertilizer tanks 7, 7 are provided on both left and right sides of the driver's seat 6, respectively. Fertilizer tank 7
has a fertilizer replenishment port 8 on the top surface and a saucer 9 surrounding the fertilizer replenishment port 8. A hose 10 is connected to the bottom surface of the front part of this saucer 9, and the tip of the hose 10 is set to be located in front of the wheel 3 in plan view. Therefore, when replenishing the fertilizer tank 7 with paste-like fertilizer, even if the fertilizer spout accidentally comes off the replenishment port 8 and the fertilizer overflows, it will be caught by the saucer 9 and will be further caught by the saucer 9. The collected fertilizer falls in front of the wheels 3 via the hose 10 without splashing onto the machine. Therefore, as the aircraft advances, the fertilizer is buried in the soil by the wheels 3, which prevents the fertilizer from flowing into lakes and rivers, and also prevents it from falling into the seedling planting position, making it easier for the seedlings to be planted. Growth problems such as fertilizer withering are also prevented.
It also prevents the machine from rusting due to fertilizer.

The left and right fertilizer tanks 7, 7 have their bottoms connected to pipe 1.
1, and these pipes 11 are further connected by a plurality of flexible hoses 13 to multiple fertilization pumps 12 provided corresponding to the number of planting rows. The plurality of fertilization pumps 12 are connected by flexible hoses 14 to a plurality of indicators 15 provided at positions visible from the driver's seat 6. Flexible hoses 1 are connected to the plurality of indicators 15.
6 is connected to a fertilizing nozzle 17 provided in the planting section 5. An indicator 15 installed on the side of the driver's seat 6 is made of a transparent container, and by visually observing this indicator 15, it can be checked whether the fertilizer is being sent normally to the fertilizing nozzle 17. It has been made possible to do so.

Side floats 18, 18 are provided on both sides of the rear planting section 5, and a center float 18' is provided in the center thereof.
A bracket 19 serving as a swing support point is fixed to the side float 18 at approximately the center in its longitudinal direction, and this bracket 19 is rotatably connected and supported to the main body 20 of the planting section 5 by a link 21. The front part is supported by an adjuster link 23. Since the link 21 is integrally connected to the rod 22, by adjusting the position of the rod 22 in the vertical direction, the height of the side float 18 relative to the main body 20 can be adjusted. The planting depth is adjusted at the same time by a planting rod 24 provided in the plant.

The side floats 18, 18 on both sides are connected and fixed together by a rod 26 via brackets 25, 25, and the fertilizing nozzle 17 is fixed to a mounting plate 27 fixed to this rod 26. A triangular plate 28 is integrally welded to the fertilizing nozzle 17, and the fertilizing nozzle 17 is attached to the mounting plate 2 through an arc-shaped elongated hole 28a bored in the triangular plate 28.
As shown by the chain line with respect to 7, it is fixed with bolts so that its mounting angle can be changed.
Further, a groove guide 29 is fixed to the mounting plate 27 so as to be lined up in series in front of the fertilizing nozzle 17, and the upper surface of the groove guide 29 is provided so as to be in contact with the lower surface of the side float 18. There is. The cut groove guide 29 creates a groove on the soil surface, and
It works by burying straw on the soil into the soil to help the subsequent fertilizing nozzle 17 to form a trench, and also to relieve the pressure on the fertilizing nozzle 17.
In addition, the load applied upward from the soil surface to the fertilizing nozzle 17 is shared by the groove guide 29 being fixed to the mounting plate 27 and abutting the lower surface of the side float 18. I am trying to protect 17. Also,
As mentioned above, since the upper surface of the kerf guide 29 is supported in contact with the lower surface of the side float 18, the mounting plate 27 that fixes it can be made lighter than conventional ones. .

Fertilizer nozzle 17 fixed to mounting plate 27
The intrusion part 17a into the soil is located in front of the seedling planting position formed by the movement trajectory 24a of the planting rod 24, and the fertilizer discharge end 17b is opened to discharge fertilizer. It is positioned so as to face below a bracket 19 that serves as a swinging support point for the side float 18.

On the other hand, the center float 18' has a bracket 30 fixed to its upper surface, and a rod 31 and an adjuster link 23 are rotatably supported via this bracket 30 on brackets 25, 25 on the side floats 18, 18. It is supported by a rotatably pivoted rod 32. Of these, Rod 3
2 passes through the bracket 30 through an elongated hole, and allows the center float 18' to swing around the rod 31. Further, a groove guide 29 is fixed to the lower surface of the center float 18' by a plate 33, as shown in FIG. 6B. With this device,
Center float 18' is both side floats 18,
Although the fertilizing nozzle 17 on the center float 18' is fixed to the mounting plate 27 of the rod 26, which has the same configuration as both side floats 18, 18, the fertilizing nozzle 17 on the center float 18' is the same as the fertilizing nozzle on both sides. It is possible to maintain a stable fertilization position in this condition.

When planting with a fertilized rice transplanter equipped with the above-mentioned fertilizing nozzle of the present invention, the soil penetration part 17a of the fertilizing nozzle 17 is submerged into the soil in front of the seedling planting position set by the planting rod 24. I will do it. Therefore, the fertilizing nozzle 17 advances through the soil before planting the seedlings by the planting rod 24, and then the seedlings are planted, so that the planted seedlings P are subjected to pressure. There is nothing that will disturb that attitude. Further, since the fertilizer discharge end 17b of the fertilization nozzle 17 is located below the swinging support point of the float, which has the least vertical change, the fertilization depth does not vary based on the tilting movement of the float. A stable fertilization position can be maintained. In addition, the relationship between the planted seedlings P and the fertilization position will not change due to meandering of the machine, and the fertilizer may come into direct contact with the planted seedlings P, causing growth problems due to fertilization. No.

As mentioned above, the fertilizing nozzle attachment device of the fertilizing rice transplanter of the present invention sets the position of the fertilizing nozzle attached to the float to enter the soil at a position forward of the seedling planting position by the planting rod, and at the same time Since the fertilizer discharge end that extends and opens downwards near the swinging support point of the float, the planting posture of the planted seedlings will not be disturbed by fertilization during planting work. Furthermore, it is possible to eliminate problems such as problems with the growth of seedlings due to misalignment of the fertilization position.
