Description

[Detailed description of the invention] (Industrial application field) This invention automatically forms a fertilization groove, drops fertilizer onto both sides of the groove, and then mixes the fertilizer with soil. After that, the soil is covered with soil, a seeding groove is formed on the soil, and the seeds are sown into the groove, and then the seeds are covered with soil and compacted.

(Prior art) Conventional fertilization and seeding equipment of this type has a
There is an idea described in Publication No. 26326.

(The problem that the idea attempts to solve) Recently, the amount of fertilizer applied has been increasing year by year.

Therefore, in the above-mentioned conventional fertilization and seeding device, the fertilizer is located in two rows in a lump in the soil.
Seeds sown on the fertilized area have a long distance from the fertilizer, making it difficult for the crop to grow. On the other hand, when the roots of the crop grow to the fertilized area, the fertilizer burns due to the large amount of fertilizer. There were drawbacks that caused growth problems.

(Means for solving the problems) In order to solve the above problems, this invention
The lower ends of the fertilizer hoses 3, 3 from the fertilizer tank 2 are exposed to both sides of the fertilization furrow cutter 1, and behind the fertilization furrow cutter 1, there is a rotary tiller 4 , a soil covering disk 5 on both sides, and seeds inside. A seeding furrow cutter 8 facing the lower end of the seed drop gutter 7 from the container 6, soil covering metals 9 on both sides, and a pressure roller 10 were provided.

(Function) As shown in FIGS. 3 and 4, the topsoil is scraped to both sides by the fertilizing groove cutter 1 to form a fertilizing groove, and the fertilizer in the fertilizer tank 2 is transferred to the fertilizer hose 3 on both sides of the groove. , 3, and then, after stirring the soil in the fertilized areas on both sides with the rotary cultivator 4 , the soil on both sides that was raked by the above-mentioned fertilization furrow cutter 1 is placed on the fertilization groove with the soil covering disks 5 on both sides. Then, a seeding groove is formed on the covered soil by a subsequent seeding groove cutter 8, and the seeds in the seed container 6 fall into the groove through the seed drop gutter 7. , the above-mentioned seeding furrow cutter 8
The soil on both sides that has been scraped away is returned to the seeding groove using soil covering metals 9 on both sides, and the seeding groove is covered with soil.
As shown in Figure 5, fertilizer-mixing areas A and A are formed on both sides, seeds 11 are sown in the upper part between them, and a non-fertilizer area B is located on the ground surface. Work is done.

Configure. 30 is a cover of the rotary tiller 4 , 31 is a support rod on both sides that protrudes backward from the top of the cover 30, and at the lower end thereof, soil covering disks 5, 5 on both sides are arranged in an inverted V shape when viewed from above. Rotatably supported.

32 is a stock change mechanism mounted on each middle side of the frame 12, and 33 is a frame 1.
The wheel is constructed by an axle 34 on both sides of the center of the plant 2, and the axle 34, the input shaft 35 of the plant change mechanism 32, and the output shaft 36 of the plant change mechanism 32.
and the front rotating shaft 20 are connected to the chain transmission mechanism 3.
Connected by 7 and 38.

b is a seeding machine placed behind each rotary fertilizer applicator, 39 is a frame of seeding machine b, and a seed container 6 is attached to this.
A seed transfer plate (not shown) which is driven and rotated by a transmission shaft 40 is mounted on the inside of the seed container 6, and a seed tank 41 is attached above, and an input shaft of the plant change mechanism 32 is installed. The front and rear ends of the traction frame 42 are rotatably fitted onto the input shaft 35 and the transmission shaft 40, respectively, and the input shaft 35 and the transmission shaft 40 are connected by a chain transmission mechanism 43.

The seeding groove cutter 8 is shaped like a disk and is attached below the seed container 6, so that the lower end of the seed drop gutter 7 connected to the seed drop opening of the seed container 6 faces into the seeding groove cutter 8. The upper ends of the soil covering metals 9 on both sides are pivotally connected to the seed container 6, and the support frame 44 of the pressing roller 10 is attached to the rear end of the underframe 39.

Next, its effect will be explained. When the machine is put into the field, fertilizer is put into the fertilizer tank 2 and seeds are put into the seed tank 41, and the tractor is started to move forward, the transmission shaft 17 and the input shaft are connected to each other from the output shaft of the tractor. 16, the rotary tiller 4 rotates in the direction of the arrow in FIG. 1 via the gear mechanism in the gear housing 15, the main shaft 18, the transmission mechanism 27, and the tiller shaft 26. On the other hand, the wheel 33 rotates on the ground, and from the axle 34 to the transmission mechanism 37, transmission 32, transmission mechanism 38, 2.
2 and 43, the front and rear rotating shafts 20, 21 and the transmission shaft 40 rotate. Therefore, fertilizer tank 2
The fertilizer in the front part of the receiving box 19 is fed into the rear part of the receiving box 19 while being stirred by the stirring and sending claw of the front rotating shaft 20, and into the sending gutter 23 by the scraping piece of the rear rotating shaft 21. The fertilizer is splashed into the fertilizer hoses 3, 3 and falls from their lower ends to both sides of the groove cutter 1. On the other hand, the seeds 11 in the seed container 6 are sequentially fed out by the transfer plate, fall into the drop gutter 7, and fall into the groove cutter 8.

Therefore, while the topsoil is scraped to both sides by the groove cutter 1 to form a fertilization groove of the required depth and width, fertilizer is applied to both sides of the groove from the fertilizer hoses 3, and then the fertilized groove is removed. Rotary cultivating body 4
The fertilizer and soil on both sides of the fertilization groove are stirred by plowing, and then the soil on both sides that has been scraped off by the furrow cutter 1 is returned onto the fertilization groove using the soil covering disks 5 on both sides, and the soil is covered with the soil.

Next, a groove cutter 8 is used to scrape the central part of the covered soil to both sides to form a narrow seeding groove of an appropriate depth, and seeds are sown into the groove from the seed drop trough 7. The soil on both sides that has been pushed away is returned to the seeding groove using soil covering metals 9 on both sides and covered with the soil, and the top is pressed down with pressing rollers 10 to carry out fertilization and seeding operations.

(Effect of idea) This invention has the following remarkable effects.

(1) Fertilizer is applied in two rows at appropriate intervals, and the soil in the fertilized area is stirred with a rotary tiller, so the soil in the area where the seeds will be sown will become swollen and soft due to tilling, making it easier for crops to grow. In addition to promoting growth, the fertilizer is evenly mixed with the soil over a wide area, making it easier to decompose.

(2) Since the seeds are sown in the upper part between the fertilizer mixing areas on both sides, even if there is a large amount of fertilizer, the fertilizer is dispersed and acts effectively on the crops over a long period of time, preventing fertilizer burn and growth problems in the crops. Prevented.

Therefore, it is good for all agricultural crops such as beets, potatoes, beans, etc. and yields high yields.

(3) On the fertilization trench where the fertilizer and soil have been mixed, the soil on both sides that was initially scraped with the fertilization trench cutter is returned using the soil covering disks on both sides, and then covered with the soil, and the seeds are sown in the center of the covered soil. Because the soil is covered with soil, the topsoil on the furrows where fertilizer has been applied and seeded is fertilizer-free, making it difficult for weeds to grow and allowing fertilizer to work effectively.

(4) Fertilization, mixing fertilizer and soil, covering soil, sowing, covering soil,
Since the suppression work is performed mechanically in a series, the work can be done accurately and efficiently.

(5) The structure is simple and can be manufactured easily and inexpensively.
