In growing crops, applying fertilizer is a necessary task from the viewpoint of helping growth and increasing yield.
Conventionally, as shown in FIG. 18, fertilizer muscles G are continuously sprayed on the side portions of the seed group S that has been spot-seeded as side fertilization.
In recent years, it has been required to reduce the amount of fertilizer application due to the increase in fertilizer prices. For example, change from full-scale application of fertilizer to the field to side-row fertilization where the fertilizer is intensively applied only to the side of the sowing position, or from application to the soil surface to application to the soil. doing.

Thus, although it has changed from full surface spraying to side row fertilization and from surface spraying to soil spraying, there are still many portions where fertilizer is wasted. For example, even in the case of spot seeding in which seeds are sown at intervals, the fertilizer is streaked along the seeds so that the fertilizer is laterally fertilized. Most of the fertilizer was wasted without exerting the effect of the fertilizer.
Therefore, the present invention provides a point-seeding-type fertilizer seeding machine for spotting seeds at a predetermined interval and spotting fertilizer at a predetermined interval on the side in accordance with the position of the seeds seeded. The task is to do.

  The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

  In Claim 1, the spot-seeding type seeding machine which seeds a seed group at a fixed interval, and the spot-seeding type fertilizer which fertilizes a fertilizer group at a fixed interval are arrange | positioned on right and left, Is a spot-seeding-type fertilizer sowing machine in which the fertilizer group is spotted together adjacent to the seed group at a position near the spot sowing position of the seed group and where the fertilizer does not affect the seed.

  In Claim 2, in the spot sowing-type fertilizer sowing machine according to claim 1, a seed feeding device and a fertilizer feeding device are provided in each of the spot sowing-type seeding machine and the spot sowing-type fertilizer, and the seed and the fertilizer are fed out. A partition groove formed on the outer periphery of the non-sliding-side feeding roll of the feeding roll, wherein the feeding roll of the device is configured so that the feeding amount can be adjusted by fitting the non-sliding-side feeding roll and the sliding-side feeding roll. In the state where the bow-shaped partition guide plate is fitted, the feeding roll is configured to rotate, and the partition guide plate prevents the seed and fertilizer from dropping into the seed and fertilizer insertion groove of the feeding roll, From the position where the partition guide plate disappears, it is possible to move the inserted seed and fertilizer over the entire width of the insertion groove of the feeding roll, and the seed group and the fertilizer group in a state where the seed and the fertilizer have moved into the wide groove. As a composition for spotting as A.

  In Claim 3, it is set as the structure which drives simultaneously both the feeding roll of the feeding apparatus of the said point sowing type seeding machine and the feeding roll of the feeding apparatus of the said point sowing type fertilizer machine in the spot sowing type fertilizer seeding machine of Claim 2. Is.

  As the effects of the present invention, the following effects can be obtained.

  Since it comprised like Claim 1, the fertilizer can also be fertilized to a narrow location with a space | interval by spot sowing beside the seed group which sowed the seed. Therefore, since the fertilizer is not applied in a streak shape in parallel with the seed sowing position as in the conventional side-row fertilization, the fertilizer is not sprayed wastefully.

  Since it comprised like Claim 2, by limiting the insertion groove | channel of a feeding roll with a partition guide plate, the capacity | capacitance of the insertion groove | channel of a feeding roll can be restrict | limited, A capacity | capacitance restriction | limiting can be cancelled | released and dropping can be made. The seeds and fertilizer fell at a stretch, so that they could not be striped, and sowing and fertilization became possible.

  Since it comprised like Claim 3, the seed to be spotted and the fertilizer to be spotted fall simultaneously, and it became possible to reliably spot the fertilizer on the side of the seed soaked by spotting.

  The performance particularly required in the powder particle feeding device is that the accuracy of the feeding amount and the shape of the feeding material are ensured, that is, there is no cracking, crushing, or peeling of the coating material. In addition, depending on the work, it is also necessary to have accuracy of intermittent feeding for spotting. However, the feeding accuracy, which is the accuracy of whether the feeding amount is constant, the seeding accuracy, which is the accuracy of feeding the feeding material intermittently at a certain distance, and the initial shape of the feeding material are damaged or deformed. There is a need for shape securing accuracy that does not occur, but these accuracy are contradictory items that are highly likely to affect the other if too much is obtained.

  In order to improve the seeding accuracy, a method of holding the feed by a guide until just before being discharged from the roll is often used. However, since the feed is continuously held between the roll groove and the guide for a long distance and time, the feed is cracked when the feed amount is large, and the coating is coated when the coating material is coated. A lot of material peeling occurs.

  In order to improve the accuracy of the number of grains of the feed, which is the feed accuracy, a method of scrubbing the feed that overflows from the roll groove with a brush or the like is used. In this case as well, scraping the overflowing part may cause cracking or peeling of the feed, and wear on the scraped brush, etc., requiring labor and expense for parts replacement, etc. It becomes. Moreover, there are various feed objects in the feed, and the particle sizes thereof are different. Since the amount of feeding differs depending on the situation, it is necessary to be able to change the opening, which is the size of the roll groove. However, when the number of strips increases, time and labor for adjusting the amount of feeding are required.

  For this reason, there is a roll type seeder equipped with a mechanism for adjusting the opening degree of all the strips at once. However, since there is a difference in solids depending on component accuracy, a mechanism capable of individual adjustment is also necessary. Moreover, since the spacing of the seeding varies depending on the feed, it is necessary to provide a striation adjusting mechanism that allows the entire feeding section to move. In addition, in special machines such as direct sowing of paddy rice straw, a full-row opening adjustment mechanism and a streak mechanism are used, but the streak is fixed and it is impossible to adjust the streak.

  Next, the feeding mechanism will be described with reference to FIGS. In the slide roll type feeding device, when the feeding mechanism of the slide roll type feeding device is made to be a pumping type, the feeding material that cannot enter the roll groove portion 9a falls by its own weight, and a large amount of feeding material does not go into the groove unnecessarily. It is configured as follows. When the feed comes into the upper part of the slide rolls 9 and 10, the roll brush 25 is present, so that the feed entering more than the roll groove 9a is scraped. Thereby, the number accuracy is improved. Since a large amount does not enter the roll groove portion 9a by the pumping method, the amount that can be worn by the upper roll brush 25 is reduced, and cracking of the feed and peeling of the coating material are reduced. In addition, wear of the roll brush 25 can be suppressed.

  Next, after the feed is positioned above the slide rolls 9 and 10, the shielding plate constituted by the partition guide plate 18 is eliminated, and the longitudinal groove width of the roll groove portion 9a is all opened and widened. .

Even when passing through a portion of the outer peripheral guide 26 provided after (on the front side) after the roll brush 25, an allowance is formed between the roll brush 25 and the outer peripheral guide 26, leading to reduction of cracks and coating peeling.

  In addition, since the feed is arranged in the roll groove portion 9a configured in the direction perpendicular to the traveling direction, the landing shape on the field, that is, the length in the traveling direction becomes shorter than usual, and the spot seeding accuracy can be improved. . The outer periphery guide 26 is pivotally supported by an upper pivotal support portion 26a, and can be rotated with the lower side as a rotation side. By holding the delivery to the discharge point by the outer periphery guide 26, the delivery can be released to the field in a lump, leading to improvement in spot seeding accuracy. The outer peripheral guide 26 is not fixed, but can be swung to reduce cracks in the feeding material caused by friction and peeling of the coating material.
