Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention applies fertilizer to a shallow layer and a deep layer in a field at the same time as planting or sowing of seedlings in a rice transplanter or a submerged direct sowing machine. Regarding paddy field working machines, especially in paddy field working machines in which the fertilizing effect of the deeply fertilized fertilizer on each seedling planting or sowing line is almost equal, when the seedling planting or sowing line is odd. The present invention relates to a fertilizer application device.

[Conventional technology]

Conventionally, shallow fertilizer is applied simultaneously to the shallow and deep layers of the field in parallel with planting or sowing of seedlings, and fertilizer is applied to the shallow lateral part near the seedlings or sowing seeds. A fertilizer is provided corresponding to each line, and a fertilizer is provided with a deep fertilizer in each deep line for fertilizing a slow-release fertilizer at a deep part almost in the middle between the seedling or sowing lines. A paddy working machine having the same has been proposed by the present applicant. Immediate-acting fertilizers are absorbed during the initial breeding of planted seedlings or sown seeds to improve their growth, while slow-acting fertilizers are absorbed by the roots that have developed after the initial growth and have a long-term fertilization effect. That is what you can expect.

[Problems to be solved by the invention]

By the way, the above-mentioned prior art fertilizer applicator can be applied as it is in the case of planting even-numbered plants such as four, six, eight, etc. or even sowing, and is convenient. In the case of sowing in a row, there was a problem that the deep fertilizer applied fertilizer with slow-release fertilizer for each strip would not be fertilized for one row.

Therefore, an object of the present invention is to provide a fertilizer apparatus in a paddy field working machine that can perform even fertilization even in the case of odd-numbered planting or odd-numbered sowing, and obtain an even fertilizing effect.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a paddy field working machine adapted to simultaneously fertilize a shallow layer and a deep layer of a field in parallel with planting or sowing of a seedling, Odd numbered lines, shallow fertilizer application sections shall be provided for each line to apply fertilizer to the shallow layer near the seedlings or sowing lines. A first deep fertilizer section for fertilizing a deep portion is provided for each strip,
A second deep fertilizer is provided at a deep portion below the remaining one seedling planting or sowing line, and a distance between the fertilizer fertilized by the first deep fertilizing unit and the seedling planting or sowing line. And the distance between the fertilizer fertilized by the second deep fertilizer and the seedling or sowing line is set to be substantially equal.

[Action]

With the above configuration, the distance between the slow-release fertilizer fertilized by the first deep fertilizer and the second deep fertilizer and the planted shoots or sown seeds is substantially equal,
It is absorbed almost evenly by the roots that have been developed together with the initial breeding, and long-term fertilization is expected.

Here, the fertilizer is pumped separately into five pipes, and the immediate-acting fertilizer A is supplied to and discharged from each of the five fertilizing pipes 15 via the control unit 21, and the discharged immediate-acting fertilizer A is: As shown in FIG. 3, the seedlings P planted on the rice field surface by the planting body 11 are arranged at regular intervals in the lateral shallow layer at the root of the seedlings.

The first deep fertilizer application pipe 16 is supported diagonally forward from the side floats 9 and 9 at a position substantially at the center between the studs of the seedlings, and a guide 22 is provided on the front side thereof. The main body of the attachment device 4 is in communication with a fertilizer delivery funnel 25 of first slow-release fertilizer tanks 24, 24 for receiving the slow-release fertilizer supported by the stays 23. First slow-release fertilizer tank
A delivery roll 26 provided below the 24 receives rotation power from a drive mechanism of the planting body 11 via a bell crank 27 and a connecting rod 28 and rotates to deliver the fertilizer.
The slow-release fertilizer B ₁ which is fertilization, planting was seedling P
At deep position of the root of the depth below L ₁ (about 12cm), and are as the distance between the left and right upper seedling P is equal position.

The second deep fertilizer pipe 17 is supported obliquely downward from the center float 8 such that its tip is a deep part immediately below the central single seedling P, and a guide is provided in front of it.
29 is provided and communicates with the fertilizer delivery funnel 25 of the second slow-release fertilizer tank 30 for containing the slow-release fertilizer supported by the stay 23. Second slow-release fertilizer tank 30
As is clear from FIG. 1, is supported by a stay 23 on one side (the right side in the drawing) from the center line of the center float 8 on the side opposite to the left and right inclination directions of the second deep fertilizer pipe 17. The feeding roll 26 is driven via the connecting rod 28. And fertilized slow-release fertilizer B ₂

cm), slow-release fertilizer B ₁ fertilized in the first deep fertilizer tube 16
Is approximately equal to the distance L ₂ to the seedling P, and the fertilization amount is
Uezukenae are set to be approximately half of the slow-release fertilizer B ₁ in consideration of the fertilizer effect of to 2 Article fraction seedling planting considering corresponding Koeko § 1 minute.

When the rice transplanting operation is performed by the riding type rice transplanter configured as described above, the rice is slid on the paddy field while the planting section 4 is pulled by the riding body 2, and the planting body is leveled by the floats 8 and 9. 11 draws the planting locus C, takes out the seedlings placed on the seedling placing stand 10 one by one, and plants them as planted seedlings P at a substantially constant depth and a constant posture. At the same time as the seedling planting operation, the fertilizing device 14 performs a fertilizing operation.

In the fertilizer application device 14, the immediate-effect fertilizer in the immediate-effect fertilizer tank 18 is pumped through the hose 19, the pump 20, and the control unit 21 to the shallow fertilizer application pipe 15, and each seedling P planted as shown in FIG. Fertilizer A is applied to the lateral shallow part of the soil. The slow-release fertilizer in the first slow-release fertilizer tank 24 and the second slow-release fertilizer tank 30 is connected to the bell crank in synchronization with the operation of the plant 11.
27, feeding roll 26 receiving power via connecting rod 28
The fed out by a predetermined amount, it is fertilized in the deep layer as slow-release fertilizer B ₁ and B ₂ from the first deep fertilization tube 16 and the second deep fertilization tube 17 through the manure feeding funnel 25. The distance between the planting seedlings P in the slow-release fertilizer B ₁ and B ₂ are approximately equal, the fertilization amount B ₂ is approximately half of the B _1.

When the slow-release fertilizer is fertilized, the first and second deep fertilizer application pipes 16 and 17 are located forward of the seedling planting position by the planting body 11 and are located in a field opened by the guides 22 and 29. The fertilizer is applied, but the mud separated into right and left when the grooves are opened by the guides 22 and 29 is leveled by the floats 8 and 9, and then the seedlings are planted by the planting body 11, so that there is no adverse effect. In particular, in the second deep fertilizer application pipe 17, since the tip of the pipe is obliquely inserted into the soil so as to reach just below the seedling attachment strip, leveling the ground with the center float 8 and then planting the seedlings poses a problem. The traction resistance that has been displaced by penetrating into the soil from the oblique direction and moving as shown by the arrow in FIG.
To induce a push-up force F in a direction to rotate the fertilizer counterclockwise, but the second slow-release fertilizer tank 30 is disposed to be offset to the side opposite to the inclination direction of the second deep fertilizer application pipe 17. As a result, the load is offset and the balance is maintained, and the planting section 14 is held substantially horizontally, so that stable seedling planting and fertilizing work are performed.

The seedling P thus planted and the fertilizer-applied immediate-acting fertilizer A and the slow-acting fertilizers B ₁ and B ₂ absorb the immediate-acting fertilizer A at the time of initial cultivation of the seedling P and accelerate the cultivation. Then, the roots that have developed thereafter absorb the slow-release fertilizers B ₁ and B ₂ , so that long-term fertilization can be obtained. Since the slow-release fertilizers B ₁ and B ₂ are fertilized in a deep layer, there is almost no run-off and they can be used effectively.

Further, in the above-described embodiment, the case where the present invention is applied to a riding type rice transplanter is described. However, the present invention is not limited to a riding type rice transplanter, and can be similarly applied to, for example, a flooded direct sowing machine, a transplanting machine, and the like.

〔The invention's effect〕

As described above, according to the fertilizer applicator in the paddy field working machine of the present invention, the fertilizer is applied to the shallow layer and the deep layer of the field in parallel with the planting or sowing of the odd number of seedlings, and the seedling sowing or sowing. The first deep fertilizing part for fertilizing the deep part at the substantially central part between the seedling planting or sowing strips is associated with the deep fertilizing part for fertilizing the lateral shallow part near the row for each row. A second deep fertilizing section for fertilizing the remaining one seedling planting section or a deep portion below the seeding section, and providing a first deep fertilizing section, a second deep fertilizing section, and a seedling planting section. Alternatively, since the distance from the sowing line was set to be substantially equal, the shallow (rapid-acting) fertilizer works to activate the initial growth of the planted seedlings or the seeds sown, and the roots developed after the initial growth. Absorbs the first or second deep (slow-release) fertilizer, thereby providing long-term fertilization It can be expected.

In addition, since the first deep fertilizer and the second deep fertilizer have the same distance from the planted seedling or the sowing seed in the vicinity thereof, an even fertilizing effect can be obtained on the crops. it can.

In addition, shallow fertilization and deep fertilization can be performed in a single process in parallel with seedling planting or sowing for odd number of seedlings or sowing, and efficient work can be performed, and the rice field is disturbed. Nor.
