DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is used, for example, when it is intended to grow grass, flowers, etc. over a wide area on an appropriate slope surface such as a concrete retaining wall. This invention relates to a seed spraying machine for afforestation, which adds seeds, fertilizer, water, etc. to soil, stirs the mixture, and sprays and fixes the stirred sprayed material onto the surface of a retaining wall or the like.

(Prior art) Conventionally, most of this type of seed spraying machine has an opening at the bottom of the agitation tank, a suction reservoir that communicates with the opening, and a pump that connects the suction reservoir with the pump. The material to be sprayed, which is stirred in the stirring tank, is fed to the suction reservoir from the opening 4 at the bottom of the stirring tank, and is then sent to the pump via the suction pipe. It is designed to reach the target and be sprayed via a pump.

(Problems to be solved by the invention) However, in the case of the seed spraying machine as described above,
There was a problem in that the opening of the stirring tank was easily clogged, and once clogged, the efficiency of the spraying operation was significantly reduced. In addition, the material to be sprayed tends to settle at the bottom of the suction reservoir, making it difficult to transport the material within the suction reservoir.

(Means for Solving the Problems) Therefore, the present invention provides a seed spraying system in which soil, fertilizer, water, and seeds are stirred in a stirring tank 1, and the agitated object to be sprayed is appropriately sprayed through a pump 15. Machine S
An opening 4 communicating with the suction reservoir case 3 is provided in the bottom wall of the stirring tank 1. A plurality of sieve pieces 5 are arranged in this opening 4 at appropriate intervals.
Further, a scraping piece 8 is attached via an attachment arm 7 to the shaft 2a of the stirring blade body 2 which is driven and rotated within the stirring tank 1. Moreover, this scraped piece 8
is formed so that it can come into contact with the hole edge portion of the drop slot 6 located between the adjacent sieve pieces 5. In addition, by adopting a means for mounting a fluidizing blade body 10 that is driven and rotated in the suction sump case 3 fixed to the lower part of the stirring tank 1, the above-mentioned difficulties can be reliably solved. .

(Function) Therefore, the material to be sprayed, which is made by adding fertilizer, water, and seeds to the soil and stirring it, is stirred in the stirring tank 1, and then the opening that connects the stirring tank 1 and the suction reservoir case 3 is opened. It is fed into the suction reservoir case 3 via the section 4. At this time, the object to be sprayed passes through the drop slot 6 located between the sieve pieces 5 disposed in the opening 4. The object to be sprayed is fed into the suction reservoir case 3. The fluidizing blade body 10 driven and rotated within the suction sump case 3 prevents a sedimentation state from occurring at the inner bottom of the suction sump case 3. The object to be sprayed at the edge of the drop slot 6 is scraped off by the scraping piece 8 attached to the stirring blade body 2 via the attachment arm 7, and becomes muddy to some extent. A continuous object to be sprayed with adhesiveness is temporarily cut off at this scraped portion and falls into the suction reservoir case 3.

(Example) Hereinafter, the present invention will be explained with reference to illustrated examples.

(Effects of the Invention) Therefore, the present invention provides a seed spraying machine S that stirs soil, fertilizer, water, and seeds in a stirring tank 1, and sprays the stirred object to be sprayed through a pump 15 as appropriate.
An opening 4 communicating with the suction reservoir case 3 is provided in the bottom wall of the stirring tank 1, and a plurality of sieve pieces 5 are arranged at appropriate intervals in the opening 4. The scraping piece 8 attached via the attachment arm 7 to the shaft 2a of the stirring blade body 2 which is driven and rotated is configured so that it can come into contact with the hole edge portion of the drop groove hole 6 located between the adjacent sieve pieces 5. Since the fluidizing impeller 10 that is driven and rotated is installed in the suction reservoir case 3 which is formed and fixed at the bottom of the stirring tank 1, clogging at the opening 4 of the stirring tank 1 can be reliably prevented. This makes it possible to reliably improve spraying efficiency. That is, a plurality of sieve pieces 5 are arranged in the opening 4, a scraping piece 8 is attached to the stirring blade body 2 via the attachment arm 7, and the scraping piece 8 is positioned between adjacent sieve pieces 5. Since it is formed so that it can come into contact with the hole edge portion of the drop slot 6, the continuous object to be sprayed, which is mud-like and has a certain degree of stickiness, is formed so that it can come into contact with the hole edge portion of the drop slot 6.
The portion can now be scraped off with the scraping piece 8. Moreover, since the object to be sprayed is temporarily cut at this scraped part, it falls smoothly into the suction reservoir case 3, which reliably prevents clogging of the suction reservoir case 3.
Falling inward will be promoted.

In addition, since the fluidizing blade body 10 that is driven and rotated is installed in the suction sump case 3, the object to be blown, which is fed into the suction sump case 3 from the stirring tank 1, is absorbed by the fluidizing blade 10. It is possible to constantly scrape up the bottom of the upper sump case 3 to prevent it from settling, and it is possible to smoothly suck up the material to be sprayed, and also to prevent the material to be sprayed from clogging the lower part of the opening 4, which has the above-mentioned effect. Together, they exhibit an excellent clogging prevention effect.

Furthermore, a plurality of sieve pieces 5 are arranged at appropriate intervals in the opening 4, and a fall groove 6 is formed between adjacent sieve pieces 5, so that gravel mixed in the soil can be reliably removed. You will be able to do this. Moreover, since the plurality of sieve pieces 5 are arranged at predetermined intervals along the rotational direction of the stirring blade body 2, even fibrous materials of appropriate lengths, for example, can be prevented from getting caught in the falling groove holes 6. .
In addition, gravel that cannot enter the falling groove 6 can be smoothly collected by the scraping piece 8 toward the gravel collecting section 9 in the stirring tank 1, so that it can be collected smoothly after work. It will also be possible to discharge them all at once.
