Description

[Detailed description of the invention] The present invention is configured to guide and supply seed rice or fertilizer fed from a feeding mechanism into a groove formed by a trencher, and a wet field with a soil covering body provided behind the trencher. Regarding seeding and fertilization equipment for use in plants.

In conventional seeding and fertilizing devices for wet fields of this type, the soil covering body is a trowel type that rubs the soil against the trench, or a soil covering body is placed on both sides of the trench. Since this is a soil cultivation type in which soil is raked up and backfilled into the trench using a plate, the above-mentioned trowel type applies a constant soil covering force even with the biasing force of a spring, resulting in a good soil covering effect. However, there was a problem in which the soil covering body did not work in hard muddy soil and the soil could not be covered at all, especially when the biasing force of the spring was weak. In order to adjust the biasing force, it is necessary to have a complicated structure such as adding a mechanism that can vary the biasing force to the spring, or if the biasing force is too strong because it is a rubbing method, it may not work. There is a disadvantage that the sown rice and fertilizer that have settled in the trench move with the covered soil and are unevenly distributed, and also because the soil cultivation method uses the method of raking the soil as described above,
There was a drawback that it was difficult to cover the soil reliably, and the sown rice and fertilizer would flow out together with the water on the rice field from the gaps where the soil was not sufficiently covered, making it impossible to reliably perform fertilization and direct sowing operations.

In view of the above-mentioned circumstances, the purpose of the present invention is to provide a device that eliminates the conventional drawbacks and allows reliable soil-covering work by adding a simple structure to adopt an effective soil-covering method for the soil-covering body. has.

A characteristic configuration of the seeding and fertilizing device for wet fields according to the present invention, which has been made to achieve the above object, is that the soil covering body is configured to be driven in vertical motion.

The effects of the present invention having the above characteristics are as follows.

In other words, since it performs the soil-covering action by utilizing the descending force of the soil-covering body that swings up and down, it is possible to use the descending force to backfill the soil into the trench while compacting it. Even if the muddy soil is hard, it has been possible to provide a device that can perform reliable soil-covering work without causing the soil-covering body to escape from the hard parts.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, a planting arm 4 is connected via a link mechanism 3 to a transmission case 2 which is connected to a traveling machine body (not shown) via a link mechanism 1 so as to be able to move up and down.
is mounted so as to be driven to swing, and a seedling stand 5 is installed in front of the seedling planting arm 4 in a state in which it is moved so as to be slid back and forth from side to side as the seedlings are planted. At the same time, a grounding float 6 is attached to the lower part of the transmission case 2, and a storage tank 7 is installed.
is attached to the support bracket 8, and the tank 7 is attached to the support bracket 8.
The hose 1 is attached to the feeding mechanism 9 attached to the lower part of the
A trencher 11 connected to be supplied with fertilizer through a plate member 12 is connected to the ground through a plate 12 to create a trench near the seedling planting site and is placed so as to supply fertilizer into the created trench. Attached to the float 6, it can be used for planting seedlings and applying fertilizers, etc.
In addition, it can be used for direct sowing work such as sowing rice.
It consists of a sowing and fertilizing device for wet rice fields of a riding rice transplanter.

As shown in FIG. 2, a surface layer fertilizer and a deep layer fertilizer are placed in the tank 7, which has storage spaces 7a and 7b divided into two by a partition plate 7A that is fully provided in the vertical direction. Furrowers 11A, 11A, 11B are stored in the spaces 7a and 7b, respectively, and are located directly below the spaces 7a and 7b to separately receive the two types of fertilizer flowing out from the spaces 7a and 7b.
A feeding mechanism 9 is constructed by supporting a feeding rotor 9A having receiving grooves 9a and 9b for supplying to the feeder 11B so as to be vertically swingable around a support shaft 9B.

Swing arms 9c and 4a are extended to the support shaft 9B and the planting arm 4, respectively, and both arms 9c and 4a are connected by a connecting rod 13,
In conjunction with the planting swing of the planting arm 4,
The feeding rotor 9A is driven to be able to swing up and down within a certain range below the spaces 7a and 7b.

Discharge cases 14A and 14B for independently guiding and supplying the two types of fertilizer alternately discharged by the rotor 9A are provided at the lower part of the feeding mechanism 9, and the respective cases 14A and 14B
The groove makers 11A and 11B are provided below through hoses 10A and 10B. The furrowers 11A and 11B each have a lower end set deeper into the ground surface of the deeper furrower 11B in order to form furrowing depths corresponding to the two types of fertilizers to be dispensed.

Behind the trenchers 11A and 11B, there is provided a soil covering body 15 with a U-shaped cross section that covers the fertilizer guided and supplied into the grooves formed by the trenchers 11A and 11B. , the groove creator 11A,
It is pivotally supported to be vertically swingable around a support shaft 16 that extends in contact with the front wall surfaces of the common support shaft 16 in the lateral direction, and integrally swings on the lateral outside of the groove creator 11A of the common support shaft 16. A laterally outwardly protruding shaft portion 2a of the transverse transmission shaft 2A, which extends the possible arm 16a and is disposed parallel to the width direction of the fuselage body of the transmission case 2.
The arm 2b is fixedly extended to the planting arm 4, and the arm 2b and the arm 16a are interlocked and connected by a connecting rod 17, and then the soil covering body 15 is attached to the planting arm 4.
It is configured to perform soil covering work while compacting the soil while swinging up and down in conjunction with the planting swing.

In the figure, 18A and 18B are covers provided to be vertically swingable around a horizontal axis 19 provided at the upper end of the partition plate 7A, and are provided in an inclined state so as to descend laterally outward. ing. As a result, drainage of rainwater can be improved.

Another example will be shown below.

In the spaces 7a and 7b of the tank 7,
It is also possible to have a structure in which the rice seeds and the fertilizer are stored respectively and allowed to sink to different depths, as shown in FIG.

As shown in FIG. 5, seed rice is stored in the spaces 7a and 7b, respectively, without applying a coating agent (Culper) that is usually applied during direct sowing operation, and the seed rice is stored in the spaces 7a and 7b, and
The seed rice and the coating agent may be supplied by sinking to the same depth position in the same groove in a state in which they are integrated into one body.

The soil covering body 15 is plate-shaped and is suitable when the mud surface has little moisture or when covering with fertilizer.On the other hand, when the soil is high in moisture, or when the soil is covered with seed rice, as shown in Fig. 6, it is suitable. It may be configured to have a small hole 15A for draining water. Further, instead of forming the small holes 15A, the small holes 15A may be formed into a net-like structure.
