Description

[Detailed explanation of the idea] This proposal relates to a stirrer with a magnet for Heikiub.

Nowadays, when raising cattle, heikiubu (solidified grass) brought in from the United States is soaked in water and broken down, or mechanically broken down and fed. contains a large amount of iron from wire, nails, etc., and when given to cattle, the cattle swallow all of this iron and the iron accumulates in their stomachs, resulting in many deaths of cattle. There is. In order to prevent this accident from occurring, it is important not to feed heikyubu that contains iron, but due to the pasture situation in our country, the use of heikyubu cannot be excluded.

In addition, it is almost impossible to separate solid heikyuu into those with and without iron mixed therein with a magnet.

Therefore, the applicant thought that the above-mentioned problems could be solved by providing a stirrer that could mechanically unravel the iron content and adsorb and remove the iron content, and devised the proposed stirrer with a magnet for the hei-kiubu. The object of the present invention is to provide a stirrer capable of loosening solid heikiubu and removing iron powder mixed in the heikyuubu.

In order to achieve the above objective, this project introduces solid heikiubu into a stirring tank, stirs and dissolves the heikiubu with a stirring blade that rotates in the stirring tank, and removes the iron mixed in the heikiubu. The stirring blade is a plurality of stirring blades forming a concentric circle around the center of the stirring tank, and the stirring blade is arranged on the back side in the direction of rotation of the stirring blade, and rotates on the back side. The gist is that the magnet is fixed at the rear position.

Next, an embodiment of the magnetic stirrer for use in the present invention will be described based on the drawings.

Reference numeral 1 denotes a stirring tank with a bottom and an open top. A rotary shaft 2 connected to a motor (not shown) is freely rotatable in the center of the tank 1. multiple long and short arms 3 attached to the bottom
are arranged in series, and a stirring blade 4 is fixed to the tip thereof.

Although not shown, the stirring blade 4 extends upward from the rotating shaft 2, has an arm rod fixed to its upper part, and has a plurality of support rods connected to the arm rod extending toward the bottom. Of course, it may be fixed to the tip of the rod.

Further, reference numeral 4a denotes a central stirring blade which is close to the rotating shaft 2 and rotates on the outside in the radial direction of the rotating shaft 2, and the central stirring blade 4a is fixed to the rotating shaft 2 directly or via an arm 3.

Then, it is fixed to each of these stirring blades 4 and the center stirring blade 4a. In this case, as shown in the figure, the stirring blades 4 and 4a are fixed on the back side in the direction of rotation indicated by the arrows, and at the rear position in the direction of rotation on this back side. In other words, the heibu flows along the front surface of the stirring blade toward the rear in the direction of rotation of the stirring blade, and as soon as it leaves the stirring blade, the flow speed slows down, and there is also a tendency for it to flow curved toward the back side of the stirring blade. , a magnet 5 at the position
If it is fixed, the adsorption rate of iron will improve.

Furthermore, the risk of the iron once adsorbed separating from the magnet 5 due to the frictional resistance of the magnet 5 can be reduced. Also, since the flow speed of the heikibu is slow near the central stirring blade 4a, the central stirring blade 4a
By fixing the magnet 5 to the magnet 5, it is possible to improve the rate of adsorption and fixation of iron.

Since the present magnetic stirrer for heikibu is constructed as described above, a plurality of stirring blades 4 are connected to the rotary shaft 2.
When the stirring blades 4 rotate in a concentric circle, the stirring blades 4 scoop up the heikyubu and push it in the forward direction of the stirring blades 4, and at the same time, they fall to the rear side of the stirring blades 4,
By repeating this, the grass is broken down into individual grasses, and as the grass is broken down, iron is separated from the grass, and the separated iron is attracted and fixed to the magnet 5.

Incidentally, if the heikiubu is too hard and difficult to unravel, it is advantageous to soften the heikiubu by soaking in water or the like so that the heikiubu can be loosened in a short time.

Further, as described above, since the magnet 5 is fixed on the back side of the stirring blade 4 in the rotation direction and at the rear position in the rotation direction on this back surface, the absorption and fixation rate of iron is good for the reasons mentioned above. In addition, since the iron is fixed on the back side as described above, the iron once adsorbed is unlikely to fall off due to the contact friction resistance of the heikyuubu, resulting in a good adsorption and fixation rate.

As described above, when the iron is sufficiently loosened and the magnet 5 has attracted and fixed the iron, the rotation of the rotating shaft 2 is stopped and the broken iron is fed.

Therefore, the cows are fed heikyubu that does not contain iron, and the above-mentioned accidents can be prevented.

As is clear from the above explanation, since the present invention is constructed as described above, it is possible to stir solid heikyubu with a plurality of concentric stirring blades to break it up into individual grasses, and it is also possible to dissolve the solid grass into individual grasses. Iron contained in wires, nails, etc. mixed in the grass can be attracted and fixed with a magnet, and as a result, it is possible to feed cattle with grass that does not contain iron.Moreover, the fixing position of the magnet to the stirring blade can be adjusted by Since the magnet is placed at the rear side in the rotational direction of the stirring blade, not only does the stirring action of the stirring blade not be inhibited by the magnet, but also the magnet is placed on the rear side in the rotational direction of the stirring blade. Utilizes the fact that there is a tendency for the flow to flow backward in the direction of rotation along the rotation direction, and the flow speed slows down as soon as it leaves the stirring blade, and a tendency for the heikibu to flow curved toward the back side of the stirring blade when it leaves the stirring blade. Thus, the adsorption rate of iron by the magnet can be increased, and
Even if the grass once again comes into contact with the iron that has been adsorbed to the magnet, the contact resistance is weakened on the rear side in the rotating direction of the stirring blade, so the iron that has been adsorbed to the magnet hardly ever leaves the magnet, and its adsorption and fixation rate is reduced. can be increased extremely effectively.

Therefore, iron content such as wires and nails mixed in the heikyuu can be fed in a state in which they are almost completely removed, and this has the remarkable effect of preventing death of cattle caused by the iron content. It is effective.

Moreover, since the magnet is simply fixed on the back side of the stirring blade in the rotation direction and at the rear position in the rotation direction on this back surface, the structure is simple and it can be provided in large quantities at low cost.
