The present invention relates to a non-non-working machine in which two sprinkling apparatuses mounted on a traveling vehicle body are disposed in close proximity to each other.

In the passenger type linear wave machine as an example of the said non-non-working machine, there existed one comprised as follows conventionally. That is, the seeding device and the fertilizing device are provided in a state in which the seeding device and the fertilizing device are arranged back and forth in a working part connected to the rear part of the traveling body via a link mechanism, and the plurality of seed feeding parts in the seeding device are located above the rolling axis. It is a structure provided so that it may be located, The seeding apparatus is a structure which sends the seed which the seed | feeding-feeding part pulled out from the seed hopper as a seed storage part to the groove | channel maker provided in the stationary float through the curved hose, and performs sowing. (For example, refer patent document 1).

In addition, although it is not equipped with the seeding apparatus and the fertilizing apparatus in the state arrange | positioned back and forth in a work part, in providing a seeding device in a work part, the seed which was dispensed from the seed dispensing part without using a hose is sent out vertically. There is a configuration in which a path is formed and a plurality of seeds are collectively arranged so as to perform dot waves supplied to the package at intervals along the gas running direction (see Patent Document 2, for example).

In the passenger-type linear wave machine as an example of the said non-non-working machine, the seeding device and the fertilizing device are provided in the state in which the seeding device and the fertilizer are arranged back and forth, and are provided to the seeding device. There existed the structure provided in the state in which the upper end part of the seed storage part in the inside and the upper end part of the fertilizer storage part in a fertilizing apparatus are located in substantially the same height (for example, refer patent document 1). Moreover, in patent document 1, a seeding apparatus is comprised so that seed may be sent from the seed hopper as a seed | storage storage part to the groove | channel maker provided in the stationary float for seeding, through the curved hose.

In addition, although it is not equipped with the seeding apparatus and the fertilizing apparatus in the state arrange | positioned back and forth in a work part, in providing a seeding device in a work part, the seed which was dispensed from the seed dispensing part without using a hose is sent out vertically. There is a configuration in which a path is formed and a plurality of seeds are collectively arranged so as to perform dot waves supplied to the package at intervals along the gas running direction (see Patent Document 2, for example).

As the non-non-working machine as described above, there are ones in which a straight wave device and a fertilizing device, which are examples of the spreading device, are disposed close to each other back and forth in a state where the straight wave device is located at the rear side. And irrespective of arrangement | positioning of a wave directing device and a fertilizer, the maintenance part which enables discharge | release to the outside of the rice seed which is the spraying material which remained in a wave directing device is installed in the back side of a direct wave device, and also the fertilizer which is the spraying material which remained in a fertilizing device.

Japanese Utility Model Application No. 61-61216 (Japanese Utility Model Application Publication No. 62-172308) Japanese Patent Application Laid-Open No. 2011-130735 Japanese Patent Application Laid-Open No. 9-285206 (see Figs. 17, 18, 22, and 23).

The said conventional structure (the structure of patent document 1) can simplify a structure by setting it as the structure provided with a seeding apparatus and a fertilizing apparatus in the state arrange | positioned back and forth in a work part. For example, in equipping either the seeding apparatus and the fertilizing apparatus in the traveling body side, guide feeding is supplied over a long distance to the powder-liquid supply position set to a work part by the granulated material drawn from the apparatus provided in the traveling body side. A long guide hose, a blower for forcibly conveying, etc. are required, and there is a disadvantage in that the configuration becomes complicated. On the other hand, in the case where the seeding device and the fertilizing device are provided in a state where the seeding device and the fertilizer device are arranged back and forth, An apparatus for guiding and supplying the sieve over a long distance from the traveling body side to the granular material supply position set in the work part is unnecessary, and the configuration can be simplified accordingly.

By the way, when seeding on a pavement, it is possible to grow a plurality of seed as one tree by giving a wave as described in patent document 2, and to grow a crop in the airy or sunny state by space | separating between trees. You can. However, in the case where the seeding device and the fertilizing device are provided in a state where the working part is arranged back and forth, such a wave wave is carried out. In the conventional configuration, the seed to be fed is scattered in the curved hose, so that a plurality of seeds In many cases, it may not be possible to satisfactorily supply, and there may be a possibility that the wave wave cannot be satisfactorily performed.

Therefore, in order to solve this problem, in the said conventional structure provided with the seeding apparatus and the fertilizing apparatus in the state arrange | positioned back and forth on the work part, the path which sends out the seed | strained from the seed | feeding-out part without using a hose to the vertical direction is provided. Although it is possible to employ | adopt the structure to form, in the said conventional structure, since it is set as the structure provided in the state located more than a rolling axis center in the seed seeding part in a seeding apparatus, it has the following disadvantages.

That is, when the work part is rolled due to the inclination of the traveling body in the left and right direction, the plurality of seed feeding parts are located above the rolling axis, so that the seed feeding parts of the seeding device provided in the working part are largely positioned in the gas widthwise direction. When the seed displaced and sent vertically downward from the seed dispensing part is sown into the package, there is a fear that the seed is scattered laterally.

An object of the present invention is to provide a seeding device and a fertilizer device in a state arranged rearward and rearward on the work part, thereby simplifying the configuration, and in a state in which the seed is prevented from scattering in the transverse direction even when performing the wave wave. It is an object of the present invention to provide a non-non-working machine capable of being able to perform sowing.

The said conventional structure (the structure of patent document 1) can simplify a structure by setting it as the structure provided with a seeding apparatus and a fertilizing apparatus in the state arrange | positioned back and forth in a work part. For example, in equipping either the seeding apparatus and the fertilizing apparatus in the traveling body side, guide feeding is supplied over a long distance to the powder-liquid supply position set to a work part by the granulated material drawn from the apparatus provided in the traveling body side. A long guide hose, a blower for forcibly conveying, etc. are required, and there is a disadvantage in that the configuration becomes complicated. On the other hand, in the case where the seeding device and the fertilizing device are provided in a state where the seeding device and the fertilizer device are arranged back and forth, An apparatus for guiding and supplying the sieve over a long distance from the traveling body side to the granular material supply position set in the work part is unnecessary, and the configuration can be simplified accordingly.

By the way, when seeding on a pavement, it is possible to grow a plurality of seed as one tree by giving a wave as described in patent document 2, and to grow a crop in the airy or sunny state by space | separating between trees. You can. However, in the case where the seeding device and the fertilizing device are provided in a state where the working part is arranged back and forth, such a wave wave is carried out. In the conventional configuration, the seed to be fed is scattered in the curved hose, so that a plurality of seeds In many cases, it may not be possible to satisfactorily supply, and there may be a possibility that the wave wave cannot be satisfactorily performed.

Therefore, in order to solve this problem, in the said conventional structure provided with the seeding apparatus and the fertilizing apparatus in the state arrange | positioned back and forth on the work part, the path which sends out the seed | strained from the seed | feeding-out part without using a hose to the vertical direction is provided. Although it is conceivable to employ a constitution to be formed, the conventional constitution has a disadvantage in that the upper end portion of the seed reservoir portion and the upper end portion of the fertilizer reservoir portion are provided in a state located at approximately the same height.

There is a distance until the seed is dropped to the packaging surface after the seed is extracted, and a plurality of seeds are gathered from the seed dispensing part and spread out laterally until the fed seeds are supplied to the package, There is a possibility that it is impossible to satisfactorily supply the seeds.

In addition, in the said conventional structure, when the fertilizer is replenished to a fertilizer storage part, since the upper end part of a seeding apparatus and the upper end part of a fertilizer apparatus are in the high position of about the same level, the fertilizer accommodated in containers, such as a storage bag, for example. It is also disadvantageous that it must be lifted up to a high position to supply it, and work becomes difficult.
