Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a soil fertilizer application device for a paddy working machine such as a rice transplanter or a submerged rice soil seeder.

[Problems to be Solved by Prior Art and Invention] In general, some of the seed paddy working machines are capable of performing fertilization work simultaneously with paddy work such as planting work and seeding work. However, conventionally, the fertilization work performed in accordance with this paddy field work is merely one in which soil fertilization is applied to the side of the work line such as planting work, and in parallel with this, for example, in fertilizer. Even if both immediate-acting and delayed-acting ones are mixed, if the fertilization position is close to the working strip, even if fertilization can be expected in the early growth stage where the roots are short, the roots will grow long. When the fertilizer is applied beyond the fertilizer application position, the fertilizing effect is reduced and the fertilizer does not work effectively.

On the contrary, when the fertilizer application position is far from the working row, the fertilizing effect of the fast-acting fertilizer does not work effectively at the initial growth stage when the root is short and does not reach the fertilizer application position. However, it is difficult to expect a continuous fertilizing effect for a long period of time from the early development stage to a long root, which is usually short. The fertilization work was separately performed according to the timing.

Therefore, first and second soil fertilization means are respectively provided so that the slow-acting fertilizer and the immediate-acting fertilizer can be fertilized in the soil at different positions near and far from each other. Is advocated.

However, in providing the first and second soil fertilizing means in this manner, among the first and second soil fertilizing means, particularly, the part which is immersed in the soil from the lower surface of the gliding float is subject to mud resistance. However, if these parts are provided uniformly behind the pivotal position of the gliding float, the mud resistance will work together as a force to lift the rear part of the gliding float upward, and the front-back balance of the paddy field working unit will be increased. Damaged,
It is difficult to secure the accuracy of working depth and fertilization depth, and there is a problem that working performance is reduced.

[Means for Solving the Problem] The present invention has been made in view of the above circumstances and was devised with the object of providing an soil fertilizer application apparatus for a paddy field working machine capable of eliminating these drawbacks. The soil immersive members of the first and second soil fertilizer application methods that perform multiple soil fertilization in parallel to work strips such as seedling planting work and sowing work can swing freely in the front-rear direction. In mounting each of the sliding floats pivotally supported on the sliding float, one of the soil submersion members of the first and second soil fertilizer means is located in front of the pivotal support position of the sliding float, and the other is pivotally supported by the sliding float. It is characterized in that it is arranged behind the position and is dispersed and attached to the front and back.

Further, according to the present invention, a plurality of soil fertilizers can be simultaneously applied to the work strip by this configuration, and the ups and downs of the front and rear balance of the paddy work section can be reduced.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, 1 is a traveling type of a riding type rice transplanter,
A seedling planting section 2, which is a paddy field working section, is attached to the rear part of the traveling machine body 1 via an elevating link mechanism 3. The seedling planting part 2, the member devices such as the seedling placing table 4, the planting claws 5, and the gliding float 6 are assembled in the same manner as before, but the seedling planting part 2 is immediately effective. There is provided a first soil fertilizing means for applying a fertilizer and a second soil fertilizing means for applying a slow-acting fertilizer.

That is, as the first soil fertilizing means for fertilizing the fast-acting fertilizer, a fertilizer applying a pasty fertilizer is adopted in the examples (of course, the fast-acting granular fertilizer is continuously or intermittently applied. Needless to say, fertilization may be applied), but the fertilizer nozzles 7 are arranged on the left and right of the gliding float 6 arranged below the drive case 2a where the planting claws 5 are attached to the rear side. There is. In other words, the sliding float 6 is pivotally supported at its intermediate portion in the front-rear direction so as to be swingable back and forth on the drive case 2a via the pivot shaft 6a. The fertilizer application nozzle 7 is attached by being pivotally supported up and down in a position forward of the position of the pivot shaft 6a (pivot position), and in this state is relatively shallow near the planting strip A. Fertilization in the soil at the position is carried out in parallel with the planting work
Are being formed. Here, when working,
The portion where the fertilizer application nozzle 7 is immersed in the soil from the lower surface of the gliding float 6 is set to be located in front of the pivot position as shown in FIG. In the figure, 8 is a fertilizer tank,
Reference numeral 9 denotes a fertilizer pump, all of which are mounted on the traveling machine body 1.

On the other hand, as the second soil fertilizing means for fertilizing the slow-acting fertilizer, a fertilizer applying granular fertilizer is adopted in the examples (of course, it goes without saying that it may be a paste fertilizer), The fertilizer tank 10 is a drive case
It is supported and fixed to a bracket 11 fixed to 2a, and a fertilizer feeding device 12 is connected below the fertilizer tank 10. The actuating arm 12b protruding from the payout shaft 12a of the payout device 12 is connected to an extension portion of the crank arm 5a for actuating the planting claw 5 via a rod 13, and the crank arm for performing the planting operation. The actuating arm 12b is actuated in association with the swinging movement of the 5a, whereby the slow-acting fertilizer is continuously dispensed and the fertilizer hose is fed.
The fertilized article C is formed by dropping the fertilized article to a position farther and deeper than the immediately-applied fertilized article B via 14. Here, the fertilizer hose 14 uses a bifurcated halfway,
The drive case 2a is attached to the branch portion with the drive case 2a interposed therebetween, and the fertilizer hose 14 is configured so that the drive case 2a can be effectively used and safety can be supported.

Further, reference numeral 15 is a thin sliced body which is attached to the back surface of the gliding float 6 so as to project downward and to be immersed in the mud, which is one of the constituent members of the second soil fertilizer application means.
Is mounted in a state of being arranged rearward of the position of the pivot shaft 6a of the gliding float 6, but the lower end of the fertilizer hose 14 is disposed at the rear of the groove body 15, The fertilizer that has dropped from the hose 14 is designed to drop into the fertilizer ditch. Reference numeral 16 is a soil cover plate that covers the fertilizer ditch.

By the way, as the granular slow-acting fertilizer, in order to make the slow-acting effect more effective, a coating agent film is previously applied to the fertilizer surface, which effectively prevents the early dissolution of the fertilizer in the soil, It is more preferable if it is set so as to act effectively as a slow-acting fertilizer, but it is more convenient if it has a property of protecting the fertilizer from moisture absorption as a property of the coating agent. In addition, it is common that the immediate-acting fertilizer and the slow-acting fertilizer have different components, but it goes without saying that they may be the same depending on the type of plant, field conditions, etc. Absent.

In the embodiment of the present invention configured as described above, the planting seedlings mounted on the seedling mounting table 4 are scraped off by the planting operation of the planting claws 5 which are timed to the traveling of the machine, and are intermittently carried on the rice field. However, at the same time as this planting work, immediate effect fertilizer is applied from the fertilizer application nozzle 7 to the planting line A.
The fertilizing hose 14 continuously fertilizes the slow-acting fertilized fertilizer C at a position farther than the immediate-acting fertilized fertilizer B.

As described above, in the case where the present invention is implemented, the fertilizing work is performed at the same time as the planting work, but in this case, the immediate-acting fertilizer strip B is close to the planting strip A. Therefore, the fertilizing effect of this fertilizer works at the early stage of development where the roots are short, and the survival of seedlings and the tillering of seedlings are promoted, and the seedlings grow to be strong and secure the number of effective stems at an early stage. Then, when the seedlings grow, the roots become long and reach the site of the slow-acting fertilizer row C beyond the fast-acting fertilizer row B, this time, the slow-acting fertilizer effectively acts to grow the seedlings in the middle to late stages. The fertilizing effect against it will be obtained. As a result, fertilization work in the soil is carried out at the same time as planting seedlings, but long-term continuous fertilization effect from the early growth stage of short roots to the long-term mid-stage and even to the late stage is surely sustained. In addition, the number of additional fertilizing operations conventionally required can be reduced, and the work labor can be improved.

Moreover, in this case, since the slow-acting fertilized fertilizer C is applied to the central part sandwiched between the left and right fast-acting fertilizer fertilizer B, on the side where the root growth is promoted by the fast-acting fertilizer. Furthermore, since the fertilizing effect of the slow-acting fertilizer works, there is an advantage that the root growth is further promoted and the growth of strong and durable crops can be measured. In addition, since the slow-acting fertilizer is applied continuously, there is also an advantage that the fertilizing effect continuously acts according to the elongation of the root.

In addition, the slow-acting fertilizer and the fast-acting fertilizer can be applied to two rows of fertilizers at different distances from each other in parallel with respect to the planting strip A. The soil immersion portion of the fertilizer nozzle 7 that is immersed in the ground and receives mud resistance is located in front of the position of the pivot shaft 6a of the gliding float 6, so that the mud resistance in the direction of lifting the front side of the gliding float 6 is increased. Receive. On the other hand, the grooved body 15 that receives the mud resistance in the second soil fertilizer application is behind the pivot position of the gliding float 6, and as a result, receives the mud resistance in the direction of lifting the rear side of the gliding float 6. As a result, despite the provision of the first and second soil fertilization means on the sliding float 6, the mud resistances received by the soil submerged portions of both soil fertilization means work in directions to cancel each other. This reduces the loss of the front-rear balance of the seedling planting part 2 as in the case where both soil immersion parts are arranged behind the pivot position, and the planting depth as well as fertilizer application of each fertilizer is reduced. The depth can be made as constant as possible, and planting and fertilization work can be performed well.

In carrying out the present invention, as a means for applying a slow-acting fertilizer, for example, a feeding roll with a feeding groove is continuously rotated in one direction by swinging the crank arm described above to form a feeding groove. It goes without saying that it is possible to adopt a fertilizer that is continuously fertilized.

[Effects and Effects] In short, since the present invention is configured as described above, it is possible to perform a plurality of soil fertilization works in parallel with the paddy work for the work strip, and to correspond to the fertilizer action. Fertilization can be performed, and the number of additional fertilization operations can be reduced,
Work effort can be improved.

Moreover, of the first and second soil fertilization means that perform multiple fertilizer applications in parallel, one of them is placed in front of the pivot position of the gliding float and the other is the pivot of the gliding float. Since it is arranged behind the position, the mud resistance acting on these submerged areas is offset by the direction of lifting the front side and the rear side of the gliding float, respectively, and as a result,
Despite the provision of the first and second soil fertilization means, both mud resistances received by each submerged area are the same as those in which each submerged area is arranged on the rear side of the gliding float. It is possible to avoid working in the direction of lifting the rear side of the gliding float, reducing the loss of the front-rear balance of the paddy field working unit, and not only the working depth but also the fertilization depth of each fertilizer row. The accuracy of can be increased.
