Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a foreign matter removal device for a feeding device in a direct sowing machine in flooded soil, such as a seeding machine or a fertilizer applicator.

<Prior art> As a feeding device in a seeding machine,
As described in Japanese Patent No. 12925, a device is known in which a feed roll is provided on the lower side of the feed case, and the seeds in the reservoir of the feed case are fed out in fixed quantities by the feed roll.

In order to remove the remaining seeds from the reservoir after sowing, the side plate of the reservoir must be removed and the seeds inside must be scraped out, which is cumbersome.

Therefore, it has been considered to provide a residual quantity outlet and a shutter in the bottom wall of the reservoir, and to open the shutter and take out the seeds from the residual quantity outlet by allowing them to fall naturally due to their own weight.

<Problems to be Solved by the Invention> This makes it easy to remove the remaining amount of seeds. However, if the seeds are contaminated with dust,
Alternatively, if exfoliated seed powder is mixed in, these foreign substances cannot be separated from the seeds and removed, and the problem in this respect is the same as that described in the above-mentioned Japanese Utility Model Application Publication No. 12925/1983. If you continue to work with such foreign matter mixed in, it will accumulate on the bottom wall of the reservoir, preventing the upper seeds from flowing downward and causing stagnation, or the feeding part of the feeding roll may become clogged. There is a drawback that this occurs. In particular, in the case of a direct sowing machine in flooded soil that uses seeds coated with Culper on the outside, removal of peeled powder of Culper becomes a problem.

<Means for Solving the Problems> The present invention is intended to solve these problems, and the technical means for this purpose is to provide a granular material to be delivered in the reservoir on the lower side of the delivery case. In a feeding device for a direct seeder in flooded soil, which is equipped with a feeding roll that feeds out the amount of material to be fed, a remaining amount outlet for taking out the remaining amount of the material to be fed out on the bottom wall of the reservoir, and a shutter that opens and closes this. Shutter grooves are provided on both sides of the mouth edge of the outlet, and a flat plate-shaped shutter is inserted into the shutter groove so as to be freely inserted and removable to close the remaining amount outlet, and a portion of the shutter corresponding to the remaining amount outlet is The feature is that a plurality of slits are formed in the width direction in the direction of insertion of the shutter so as to pass foreign matter such as dust and peeling powder smaller than the object to be fed out, and the end of the slit where the shutter is inserted is open. be.

<Function> Since the shutter 30 is provided with a slit 33, if foreign matter such as dust or peeling powder is mixed in the object 17 to be fed out, and if it is smaller than the object 17, it can be removed through the slit 33. It can be separated and removed to the outside of the reservoir 16.

Furthermore, since the slit 33 is formed in the insertion direction of the shutter 30, when the shutter 30 is removed from the shutter groove 29, the material 17 on the shutter 30 is smoothly removed at the edge of the remaining amount outlet 28. Object to be fed out between shutter 30 and mouth edge
17 is effectively prevented from being bitten, and in the case of the delivered object 17 coated with culper, peeling of the culper, epidermis, etc. is prevented. Furthermore, since the end of the slit 33 where the shutter 30 is inserted is open, even if the object 17 gets caught in the slit 33, the slit 33 can be easily expanded and the end where the shutter 30 is inserted is opened. Easily removable by tapping on the side.

<Example> Hereinafter, the present invention will be described in detail with reference to the illustrated example. Fig. 2 shows a submerged soil direct seeding machine, 1 is a machine body equipped with an engine, etc., and drive wheels 3 are connected to each other through transmission cases 2 on both sides. is provided. A support frame 4 projects rearward from the body 1, and a handle 5 is provided at the rear end via an upwardly curved portion.
6 is a main float, which is arranged on the lower side of the fuselage 1. Reference numeral 7 denotes a transmission case, which is supported by the frame 4 by a support shaft 8. The transmission case 7 is provided with a pair of upper and lower tool bars 9 and 10 that extend left and right, and the upper tool bar 9 is provided with a seed tank 1.
1. The lower toolbar 10 has a seeding float 12
A pair are provided on each side.

The seed tank 11 has a feeding device 13 on the lower side. As shown in FIG. 1, the feeding device 13 includes a feeding case 14 connected to the lower side of the seed tank 11, and a feeding roll 15 rotatably provided at the bottom of the feeding case 14 and having a feeding recess 18 on the outer periphery. The seeds 17 in the reservoir 16 of the delivery case 14 are delivered by the rotation of the delivery roll 15. A drive shaft 19 mounted on the transmission case 7 is inserted through the delivery roll 15, and the delivery roll 15 is rotationally driven by the drive shaft 19.
A seeding chute 21 is provided below the outlet 20 at the bottom of the case 14 .

The seeding float 12 is connected to a link 22 fixed to the lower toolbar 10. The seeding float 12 has a notch 23 that is recessed from the rear side.
is formed, and a groover 2 is formed corresponding to the notch 23.
4 and a soil covering member 25 are provided in the front and rear, and a seeding guide plate 26 that connects the lower end of the seeding chute 20 is provided in the middle thereof.

As shown in FIGS. 1 and 3, a remaining amount outlet 28 is formed in the bottom wall 27 of the feeding case 14 so as to be located near the feeding roll 15.
A shutter groove 29 is formed on the edge of the remaining amount outlet 28.
is formed. A shutter 30 is removably inserted into the shutter groove 29, and the outlet 28 can be opened and closed by the shutter 30.
The shutter 30 is made of a plate material such as an iron plate or a plastic plate, and the shutter 30 is made of a plate material such as an iron plate or a plastic plate, and has an outlet 28 as shown in FIGS. 4 and 5.
A small hole-shaped sieve portion 32 is formed in a portion corresponding to the seed 17 so that only foreign matter 31 such as dust and exfoliated powder smaller than the seed 17 passes through. In this case, sieve part 3
2 is a plurality of slits 33 formed in the insertion direction of the shutter 30 and smaller in width than the seeds 17;
and a thin rod 34 between them,
The end of the slit 33 into which the shutter 30 is inserted is open, so that the shutter 30 is shaped like a comb. Further, each slit 33 of the shutter 30 is formed in the longitudinal direction along the rotational direction of the feed roll 15 so as not to impede the flow of the seeds 17. Note that 35 is a knob for insertion and removal.

In the above configuration, during seeding, the drive shaft 19 rotates the feed roll 15, and the feed case 14 is rotated by the drive shaft 19.
Seeds 17 in the reservoir 16 are fed out in fixed quantities and dropped through a feeding outlet 20 and a seeding chute 21, and the seeds 17 are sown directly into the grooves formed by a trencher 24 and covered with soil with a soil covering member 25.

When the seeds 17 are fed out with the feeding roll 15,
Seeds 17 in the seed tank 11 sequentially flow down into the reservoir 16. On the other hand, if the seeds 17 contain foreign matter 31 smaller than the seeds 17, such as dust or exfoliated powder, they will be separated by the sieve part 32 of the shutter 30 and fall downward as shown in FIG. 1
There is no accumulation on the bottom side of the roll 6 or clogging in the recess 18 of the reel roll 15 as in the conventional case, and a predetermined reel performance can be maintained over a long period of time. The sieve part 32 is made up of slits 33 and narrow rods 34, and the direction thereof is the same as the direction of rotation of the feed roll 15, that is, the flow direction of the seeds 17. There is no problem with the flow of the seeds 17, nor does it promote the peeling of the seed 17's culper, epidermis, etc.

When removing the remaining amount of seeds 17, by pulling out the shutter 30 in the direction of the arrow, the seeds 17 in the reservoir 16 can be removed by gravity. In addition, since the slit 33 is formed in the insertion direction of the shutter 30, when the shutter 30 is removed, the seeds 17 on the shutter 30 are smoothly removed at the mouth edge of the remaining amount outlet 28, and the seeds 17 are removed between the shutter 30 and the mouth edge. The seeds 17 will not be bitten between the seeds 17, and from this point as well, peeling of the seed 17, such as its culper and epidermis, can be prevented. Furthermore, since the shutter 30 has a comb tooth shape in which the end of the slit 33 into which the shutter 30 is inserted is open, even if the seeds 17 are bitten into the slit 33, the slit 33 can be easily expanded, and the shutter 30 can be easily expanded. 30 can be easily removed by tapping the insertion end side.

Note that the present invention is not limited to a seeding machine, and can be similarly applied to a dispensing device for a fertilizer applicator that dispenses granular fertilizer.

<Effects of the Invention> According to the present invention, even if foreign matter such as dust or peeling powder is mixed in the material to be fed out, it can be removed from the slit of the shutter to the outside of the reservoir, thereby preventing accumulation within the reservoir. , it is possible to prevent clogging of the feeding roll and maintain the performance of the feeding device over a long period of time. Moreover, it has a simple structure in which a slit is formed in the shutter that opens and closes the remaining amount outlet, so it can be easily implemented. In addition, since the slit is formed in the insertion direction of the shutter and the insertion end side of the shutter is open, it is possible to prevent peeling of the culper, skin, etc. of the feed material on the insertion/removal side of the shutter, and also prevent the slit from being caught in the slit. It has the advantage that even the stuff to be fed out that is stuck therein can be easily removed.
