Description

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

Nowadays, when raising cattle, cows (solidified grass) imported from the United States are soaked in water and broken down, or mechanically broken down and fed. It is contaminated with iron from wires, nails, etc., and when given to cattle, the cattle swallow the iron together and the iron accumulates in their stomachs, causing many accidents in which cattle die. 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. Furthermore, it is almost impossible to separate solid heikibu into those with and without iron mixed in 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 at the same time adsorb and remove the iron content. The purpose is to provide a stirrer that can dissolve iron and remove iron.In order to achieve this purpose, the present invention introduces a solid hei-ki-bu into a stirring tank and rotates the hei-ki-bu in the stirring tank. This is a magnetic stirrer for hei-ki-ubu that uses a plurality of stirring blades to stir and loosen the hei-ki-ubu and remove iron mixed in the hei-ki-ubu, and the point is that a fixed blade with a magnet fixed thereon is provided in the stirring tank. That is.

Next, an embodiment of the magnetic stirrer according to the present invention will be described based on the drawings.

1 is a stirring tank with a bottom and an open top, and in the center of the tank 1 is a rotating shaft 2 that is linked to a motor (not shown).
A plurality of long and short arms 3 are connected to the rotary shaft 2 and run along the bottom close to the bottom, and a stirring blade 4 is fixed to the tip of the arm 3.

Although not shown, the stirring blade 4 includes:
Of course, the rotary shaft 2 may be extended upward, an arm rod may be fixed to the upper part, a number of support rods extending toward the bottom may be connected to the arm rod, and the arm rod may be fixed to the tip of the support rod. It is.

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.

Further, a magnet 5 is fixed to the side surface of the stirring blade 4 and the central stirring blade 4a, or to the back side of the stirring blade in the rotating direction. As for the fixing, it is preferable to fix the stirring blades 4 and 4a on the back side in the direction of rotation indicated by the arrows, as shown in the figure, and on the rear side. That is, the heikibu flows along the front surface of the stirring blade toward the rear in the rotational direction of the stirring blade,
As soon as it leaves the stirring blade, the flow speed slows down, and there is a tendency for the iron to curve toward the back side of the stirring blade, so fixing the magnet 5 at this position improves the adsorption rate of iron. Furthermore, since it is fixed on the back side, it is possible to reduce the risk that the iron once adsorbed will separate from the magnet 5 due to the frictional resistance of the magnet. In addition, the flow speed of the heikibu is slow near the central stirring blade 4a, so the central stirring blade 4a
By fixing the magnet 5 to a, the rate of adsorption and fixation of iron can be improved.

Further, reference numeral 6 denotes a large number of fixed blades fixed to the inner wall of the stirring tank 1, and the fixed blades 6 include members such as angles having a triangular cross section in the vertical direction and in the rotational direction of the stirring blade 4 shown by the arrow. The magnet 5 is fixed to the fixed blade 6 so as to be tilted downward to the right. As for fixing, it is preferable to fix to the inclined surface on the forward side of the stirring blade 4 in the direction of rotation, as this will give good results as will become clear later. Further, when fixing to the inclined surface, it may be fixed to the inclined surface intermittently as shown in the figure, or it may be fixed to the entire surface of the inclined surface.

Furthermore, the angle may be fixed on the inclined surface of the angle on the rear side, in other words, on the front side in the rotational direction of the stirring blade 4.

Although not shown, the fixed blade 6
Alternatively, a support rod may be provided extending downward from an arm rod fixed to the upper part of the stirring tank 1, and a substantially flat member may be fixed to the support rod.

Furthermore, the fixed blade 6 may be formed by fixing a substantially flat member upright on the bottom of the stirring tank 1. When these types of fixed blades 6 are provided, the back surface of the fixed blade 6 may be fixed. The magnet 5 is fixed to the side (the surface that does not collide with the heikibu). That is, when fixing it, it is preferable to fix it to the front side in the rotational direction of the stirring blade 4.

In addition, a combination of fixed blades 6 as described above may be provided in the stirring tank 1.

Since the present magnetic stirrer for hei-ki-bu is constructed as described above, when the stirring blade 4 is rotated through the rotating shaft 2, the stirring blade 4 scoops up the hei-ki-bu and pushes it in the forward direction of the stirring blade 4.
By repeating this process, the heikyubu is loosened into single pieces of grass, and as the grass is loosened, the iron content is separated from the single grass pieces, and the separated iron content is attracted and fixed to the magnet 5.

If the heikiubu is too hard to unravel, it is advantageous to soften the heikiubu by soaking in water or the like, since it can be loosened in a short time.

Further, as described above, since the magnet 5 is fixed on the rear side in the forward direction of the stirring blade 4, and moreover, on the rear side or side surface in the rotational direction, the absorption and fixation rate of iron is good for the reasons mentioned above.

Furthermore, since it is fixed on the back side as described above, the iron once attached is unlikely to fall off due to the contact frictional resistance of the heikibu, resulting in a good adsorption and fixation rate.

Furthermore, the particles pushed by the stirring blade 4 in the rotational direction of the stirring blade 4 collide with the fixed blade 6 and flow toward the center of the stirring tank 1 along the inclined surface 6a on the front side in the rotational direction. As soon as it leaves the fixed vane 6, the flow velocity weakens and becomes stagnant, and
Since the iron flows to the opposite inclined surface side, the iron is attracted and fixed by the magnet 5, and once the iron is attracted and fixed, the iron does not separate from the magnet 5 due to the contact friction resistance of the magnet.

As described above, when the iron is sufficiently loosened and the magnet 5 attracts and fixes the iron, the rotation of the rotating shaft 2 is stopped and the loosened iron is fed.

Therefore, the cows are fed hei kiubu which 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 has the remarkable effect of preventing cattle fatalities caused by iron content, and since the magnet is simply fixed to the fixed blade, the structure is It is easy and can be provided in large quantities at low cost.
