Furthermore, the fertilizing and seeding machine preferably covers the fertilized layer and the seeds are preferably sown to the position ditched by a ditching body 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer sowing machine for sowing seeds, vegetables, and pastures of paddy rice simultaneously with fertilization.

[0002]

2. Description of the Related Art Conventionally, a fertilizer-seeding machine that simultaneously performs fertilization and sowing while tilling is known in the structure disclosed in Japanese Utility Model Laid-Open Publication No. 56-41512.

[0003]

The fertilizer and seeder disclosed in the above publication is provided behind the tilling section with the fertilizer pipe and the seed pipe close to each other, so that the fertilizer layer and the seed layer are sufficiently separated. In addition, there is a problem that the two are easily mixed without being carried out, and that there is a problem that germination and unevenness of crop cultivation occur due to improper soil covering.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, in which a fertilizing tube 4b and a seeding tube 8a are provided behind a tilling unit 30 to provide a ground. In a fertilizer / seeder that simultaneously performs fertilization and seeding, a fertilizer tube 4b is provided immediately after the tilling unit 30, and a seeding tube 8a is provided above a fertilized layer applied behind the fertilizer tube 4b to perform seeding. I'm trying to do it.

[0005] The method is characterized in that the fertilized fertilized layer is covered with soil, and the seeding surface is sowed at a position where the groove is formed by the groove forming body 7.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a fertilizer-seeder mounted on a rear part of a traveling body A such as a tractor via a lifting support mechanism 2 such as a three-point link hitch, and a tillage device (groove device) from the front side.
3, a fertilizing device 4 comprising a fertilizing tank 4a and a fertilizing tube 4b
A gauge wheel 5 for setting the cultivation depth, a sled-like soil uniform body 6 for leveling the cultivation groove M and covering the soil, and forming a groove S by separating the covered portion to a predetermined depth. A groove body 7,
A seeding machine 8 including a seeding tube 8a and a seeding tank 8b, etc., which is located behind the rotating shaft of the grooved body 7 and drops seeds from the above-ground part, and a grooved part S seeded behind the seeding machine 8 A cover body 9 for covering the soil, a pressure-reducing body 10 composed of a roller member for relieving the covered area and a roller member for relieving the soil are arranged, and these are integrally attached to the working machine frame 1F.

Next, the configuration and relationship of each of the above elements will be described. The tillage device 3 of the illustrated example drives a tillage shaft 13 composed of a horizontal axis provided on a transmission case 12 via a transmission shaft 11 from a traveling machine body A side, and a plurality of tills arranged on the tillage shaft 13 at a predetermined seeding interval. A plurality of tillage grooves M are formed in the portion 30. The tilling part 30 covers the outside of the tilling nail 31 planted on the tilling shaft 13 rotating in the direction of the arrow with a tilling cover 32 having a soil covering space H.
An earthen body 6 is mounted and supported at the rear part of the body 2 so as to be adjustable in height. Then, the cultivation depth of the cultivation claw 31 is adjusted so that the gauge wheel 5 provided on the side of the cultivation device 3 is supported by rolling on the ground to form a cultivation groove M having a predetermined depth (about 60 mm). I have.

[0008] The fertilizer applicator 4 applies the fertilizer contained in the fertilizer tank 4a to the tilling cover 32 behind the tilling shaft 13.
The fertilizer is supplied from the fertilizer pipe 4b attached to the side of the cultivation groove M to be fertilized, and a fertilization layer M1 is formed at the bottom of the cultivation groove M. On the other hand, the grooved body 7 is configured to be able to roll by grounding a pair of left and right disks on a rotation axis in a C shape in plan view,
A groove S having a depth of about 30 mm is formed in the formed tillage groove M, and the fertilizer application pipe 4 is formed in the groove S.
b, the seeds stored in the seeding tank 8b are supplied and sown to form a seeding layer K1.

Then, the seeding layer K formed as described above is used.
1, a covering body 9, which is inclined in plan view and rolls while touching the ground, fills the groove S back to cover the soil, and a pressure-reducing body 10 rolls the covering surface from above with a predetermined load to set seeds. It is designed to be stably held inside. Note that 15
Is a grounding wheel that rolls while touching the ground and rotates the feeding wheel 17 of the seeding tank 8 b via the belt 16.

The fertilizer sowing machine 1 configured as described above and continuously performing fertilization and sowing as described above does not cultivate the front of a no-till field but only the sown part of the sown line. Since the cultivation groove M having a predetermined depth is formed by the portion 30, fertilization is simultaneously performed on the cultivation groove M while efficiently cultivating with small power, and the soil is covered with the soil covering space of the cultivation portion 30 and the soil uniform body 6.

Next, the portion where the tillage groove M is formed is positioned above the fertilizer application layer M1 by a predetermined amount.
The seeds are properly sowed from the seeding pipe 8a into the cultivated soil in the formed groove S, and the soil is covered with the covering body 9, and then the soil is compacted with the pressure suppressor 10 to perform a series of fertilization and sowing operations efficiently. It can be completed well. Therefore, the sown seeds are located on the lower layer of the fertilizer portion and are appropriately separated into upper and lower layers and are uniformly rolled with soil. Can be good.

[0012] The crop can grow healthy while effectively absorbing the nutrients of the fertilizer fertilized almost directly below and satisfactorily rooting downward. We can expect an increase in sales.

[0013]

As is apparent from the above description, according to the fertilizer seeder according to the present invention, fertilizer is applied via a fertilizer pipe in a tilling groove formed in a tilling part, and a fertilizer layer is formed. In the covered state, by sowing at a position above and above the fertilizer layer, simultaneous and appropriate fertilization and sowing work can be performed appropriately and efficiently, and the mixture of fertilizer and seeds is prevented to improve the germination and growth of the crop. Can be done.

At this time, the seeding can be performed smoothly and accurately by properly forming the groove by the groove body.
