Description

INDUSTRIAL APPLICABILITY The present invention attaches or mixes magnetic ferric tetroxide (magnetite Fe ₃ O ₄ ) to the surface or inside of fertilizers or plant seeds or pesticides, and applies electromagnetic force to these magnetic adducts to reduce paddy fields or fields. It relates to a method of supplying/spraying in the field.

Generally, when fertilizers or plant seeds or pesticides are applied to the field, they are done manually or by a machine. In the case of hands, it is possible to spray evenly, but it is difficult to work in a large area in terms of work amount, and work efficiency is poor. Therefore, work is usually performed using a machine.

The method of sowing includes direct sowing in the field or sowing in a nursery box, and the type of sowing machine, working method, etc. differ depending on the type of crop. Furthermore, it is necessary to change the seeding machine depending on the shape, size, mass, etc. of the seeds, which is not economically burdensome for farmers. The method of separating and selecting substances with different magnetism using the magnetic force of an electromagnet is mainly used for separating and selecting useful components in minerals, but it is not suitable for fertilizers, plants and pesticides that originally have no magnetism inside themselves. There are few application examples of. There is a proposal of a seeding machine for vegetable seedlings using an electromagnet or a permanent magnet (Mie Agricultural Technology Center Research Report 1979). This report uses only the powder containing electromagnets and ferric oxide as the main ingredients, while the seeding machine that uses only permanent magnets with a constant magnetic force and the powder of ferric oxide is used. There is also a proposal (Mie Agricultural Center Research Report 1985).

(Taku Maeda et al. Mie Agricultural Technology Center Research Report No. 7 37-49, 1979) (Yokoyama Yukitoku et al. Mie Agricultural Center Research Report No. 13 31-43, 1985)

The above report simply mixes ferric oxide (Fe ₂ O ₃ ) powder with a particle size of around 0.5 μ) with seeds in a volume ratio of 1:1 to an adsorption plate consisting of an electromagnet or a permanent magnet. A method of dressing seeds from which excess iron powder has been separated by magnetic attraction, installing a seedling raising box directly below the adsorption plate, and then demagnetizing the seeds to drop them into the seedling raising box and implant them in a pot etc. Is. This method is a small-scale seeding machine dedicated to a nursery box and is not suitable for mobile seeding on a large-scale paddy field or field, which is the object of the present invention, because the device is a fixed type. Furthermore, only the ferric oxide is described as the main component as the magnetic powder, and in the test, only four types are shown. In addition, since the magnetic powder alone is merely attached and detaches during use, it is necessary to develop a binder (bonding material) that adheres to each other.

The present invention utilizes ferrosoferric oxide (magnetite) as a magnetic material, and by moving the electromagnet or changing the magnetic field of the electromagnet, the magnetic adduct can be moved to any position, and a large paddy field or We have developed a magnetic additive and a seeder that can be applied to fields in large quantities and can be applied in large quantities.

A first aspect of the present invention has a granular magnetic addition body in which a magnetic material having magnetism is applied to a non-magnetic substance, an input port and an output port, and the magnetic addition is provided between the input port and the output port. A magnetic addition body comprising: a case having a movement path for moving a body; and an electromagnet that attracts the magnetic addition body and moves the magnetic addition body along the movement path by moving a magnetic field. Mobile device.
A second aspect of the present invention is the magnetic adder movement device according to the first aspect, wherein one or more electromagnets that are movable along the surface of the inner wall or the outer wall of the container are installed.
A third aspect of the invention is a moving device for a magnetic addition body according to the first aspect of the invention, in which a plurality of fixed electromagnets capable of changing a magnetic field are installed.
A fourth aspect of the present invention is the magnetic adduct moving apparatus according to any one of the first to third aspects, wherein the non-magnetic substance is fertilizer, pesticide, or plant seed.
Is.
A fifth aspect of the present invention is the moving device of the magnetic adduct according to any one of the first to fourth aspects, wherein the magnetic material is triiron tetraoxide (magnetite, Fe ₃ O ₄ ).

By using the present invention, it is possible to eliminate the mechanical driving unit, not only improve the durability, but also prevent the breakdown of the device due to the inclusion of dust and the like, it becomes possible to adjust the spray amount and spray speed by changing the magnetic force .. By imparting magnetism to a non-magnetic material, it can be applied to fertilizers, pesticides, or plant seeds that could not be used conventionally, and will contribute to the rationalization of future agricultural production.

In order to enhance the moving effect of the magnetic adduct in the above invention, a magnetism imparting material suitable for the purpose of the present invention is required. Generally, reduced iron powder is considered as a magnetism-imparting material having magnetism, but since iron has a high ionization tendency, especially in the case of a fine powder having a large surface area per unit mass, it reacts with oxygen in the presence of water to generate an exothermic reaction. Causes alpha-type ferric oxide and loses its magnetic force.

Since the exothermic amount of the exothermic reaction at that time is large, that is, the temperature becomes high, it becomes difficult to apply it as a magnetism-imparting material to a biological system which is one of the objects of the present invention. Spinel ferrite called ferrite is also suitable for the purpose of the present invention, ferrite containing Mn, Co, Ni, Cu, Zn, etc. contains heavy metals and may be decomposed by bacteria in soil, etc. Are likely to cause damage to plant growth. Therefore, only magnetite containing only iron can be used as ferrite. That is, the ferric oxide (magnetite) claimed as the magnetism-imparting material in the present invention is a result of the above reasons.

As described in the section of the problem to be solved by the invention, application of a magnetism-imparting material alone to fertilizers, agricultural chemicals, and plant seeds has a problem in mutual adhesion, and some binder (in order to strengthen adhesion and bonding) Binder) is required. Further, a material in which ferrosoferric oxide is fixed to a non-magnetic material with a binder must be gradually dissolved or dissociated in water. Furthermore, it is better that physical damage to the magnetism imparting body due to mechanical action inside and outside the moving device is small.

As a test method of destruction, put an appropriate amount of magnetism imparting body in a polyethylene bag, inflate with air by mouth, then hit the bottom of the bag 15 times with the palm to the extent that the pan bread and the magnetic addition body inside will jump up, The strength of the bag was set so that the inner surface of the bag was thinly coated with powder. It has been found that, under the above conditions, the binder that can be used in the present invention can exhibit the binding effect by mixing one or more of slaked lime and calcined gypsum as the inorganic compound and starch and PVA resin as the organic compound. Further, by adding an appropriate amount of peat moss, vermiculite, perlite, wood powder or the like in order to adjust the total volume of the magnetic adduct to a predetermined size, magnetic adducts of various shapes and sizes can be manufactured. Next, specific examples of combinations of ferric tetroxide and a binder will be shown.

When dried rice husks are coated with iron oxide black as black iron oxide HY-330 (95% or more as Fe ₃ O ₄ , particle size 100μ or less) and HY-335 (85% or more as Fe ₃ O ₄ and a particle size of 100μ or less) is used, and 70 mass fertilizer slaked lime manufactured by Katayanagi Lime Industry Co., Ltd. and calcined gypsum manufactured by Kagaku Kagaku Kogyo Co., Ltd. are used as a binder in a mass ratio to dry paddy. It was prepared in the ratio as shown in Table 1.

table 1
Dry paddy 10 10 10 10 10 10 10 10 10 10
HY-330 0.5 1 2 0 0 1 2 0 0 5
HY-335 0 0 0 1 2 0 0 1 2 0
Slaked lime 5 5 5 5 5 0 0 0 0 0
Calcined gypsum 0 0 0 0 0 5 5 5 5 0.5

Specifically, for example, 1 g of HY-330 and 5 g of slaked lime are first mixed, and then 10 g of dried paddy is mixed with the powder. When powder is observed to adhere to the surface of the paddy, water is sprinkled little by little while mixing, and the paddy is turned into individual grains, and the addition of water is stopped where the surface becomes black and then dried. Preferably, it should be spread for several days and allowed to stand.

In this process, slaked lime as a binder reacts with carbon dioxide gas in the air to form calcium carbonate, and a rice pad covered with a fairly hard black color is obtained. Similar black rice can be obtained by using calcined gypsum instead of slaked lime. When water is added to calcined gypsum, it undergoes a hydration reaction and becomes hard dihydrate gypsum. It takes about 15 minutes to complete, but it is necessary to leave it for about a day to evaporate excess water. HY-335 was created in the same way. The addition ratio of ferric oxide as a magnetism-imparting material is about 0.05-5 in terms of mass ratio to dry paddy except the above-mentioned ratio.

The addition ratio of the binder is 0.1-10 in mass ratio with respect to the magnetic material. When an electromagnet was brought close to these black rice grains, they easily adsorbed. It was also found that when the electric current of the electromagnet was cut off, it separated.

There is a material that makes small spheres with a diameter of about 10 mm made of organic materials such as wood peat and natural zeolite, and attaches small plant seeds to the surface to facilitate seeding (Atalya Farm Co., Ltd.). Mix powder of ferrosoferric oxide HY-330 or HY-335 and starch paste (manufactured by Nishiki Paste Industry Co., Ltd.) at a mass ratio of 0.1:1, apply 0.3 g on the surface of the small spheres, dry, and bring the electromagnet closer. Both coated microspheres containing HY-330 or HY-335 easily adsorbed and separated when the magnetic field was cut off. Due to the rough surface of the globules, I sprayed it with water to slightly moisten it, rolled it on the powder of ferrosoferric oxide HY-330, powdered it, and tested it with an electromagnet. The results were similar.

Chemical fertilizer 14-14-14 (commercial product) Granules were mixed with ferrosoferric oxide HY-330 powder and the starch paste in a mass ratio of 0.3:1 in the same manner as above, and this mixture was added to the mass of the granular fertilizer. Similar results were obtained when applied to all or part of the fertilizer and tested with an electromagnet. Magnetic fertilizer can be obtained by dispersing powder of ferric tetroxide in water or organic solvent during or after granulation of fertilizer and adhering it to the surface of fertilizer particles.

It was found that the non-magnetic material behaves like a magnetic material by mixing and coating ferrous fertilizers, pesticides, and non-magnetic materials of plant seeds with magnetic iron tetroxide (magnetite) from the outside. It is a claim of the present invention how to practically move the magnetic adduct. The following is a conceptual diagram of a method of moving a magnetic addition body using an electromagnet in the drawings.
The present invention is not limited to these conceptual diagrams.

Figure 1-1 is a cross-sectional view in which four electromagnets (M) are connected to the central axis at equal intervals so as to rotate along the inner surface of the cylinder, and Figure 1-2 shows multiple electromagnets (M) arranged in parallel. It is a sketch. The magnetic adduct (M.M) is charged from the charging port (I) and deposited on the bottom. When the electromagnet is rotated and energized at the position of (M)-(A), it is magnetized and the magnetic adduct (M.M) is adsorbed through the wall of the cylinder and moved to the upper part. When the current is turned off at the position of (M)-(B), which is rotated 180° from (M)-(A), the magnetic field disappears and the magnetic adduct (MM) falls to the emission port (O) with acceleration. To do. After that, this is repeated. The discharge amount can be controlled by changing the number of electromagnets, the magnitude of current, the number of rotations of the electromagnets, and the like.

FIG. 2-1 is a cross-sectional view of a device having a ring for holding electromagnets on the outside of a cylinder and having four electromagnets (M) at equal intervals on the ring. This ring rotates outside the cylinder. Figure 2-2 is a sketch of a case where a plurality of these are arranged in parallel. The four white circles are to prevent the ring from being deformed by rotation. The magnetic adduct (M.M) is charged from the charging port (I) and deposited inside the cylinder. When the electromagnet is energized and the ring is rotated, the magnetic adduct (MM) starts adsorbing through the inner wall at the position (M)-(A) and starts moving. When the power is turned off at the position (M)-(B), the magnetism becomes magnetic. Lost and fall freely to the lower outlet (O). If baffle plates are attached to the positions (M)-(B) and the position of the discharge port is set in the middle of the rings, the rotation of the rings will not be hindered.

FIG. 3 is a cross-sectional view of a device in which many electromagnets are independently fixedly arranged on the outer surface of the container and which does not have a movable part. When the magnetic adduct is deposited inside the container and the first electromagnet on the bottom is energized, the magnetic adduct is adsorbed. Immediately turning off the electric current and passing a current to the adjacent electromagnet causes the magnetic adduct to move to the adjacent electromagnet. .. By repeating this, the magnetic adduct moves. The moving amount and speed of the magnetic adduct are proportional to the strength of the magnetic force and the degree of change of the magnetic field. By arranging a large number of the electromagnets arranged in parallel, the discharge amount of the magnetic adduct increases.

FIG. 4-1 is a sectional view of a device in which a large number of fixed electromagnets are linearly arranged as in FIG. The feature is that the magnetic addition body is moved continuously by changing the magnetic field of each electromagnet. It has several baffle plates (B) so as not to move too many additional magnetic materials at once. The additional magnetic material (M.M) is deposited on the bottom from the inlet (I), and a large number of electromagnets (M) are arranged on the back surface of the bottom surface to quickly open and close the energization. Ascend and move to the outlet (O). The large number of additional magnetic bodies that first floated up were shaken off by the baffle plate (B) on the way, and the width of the passage narrowed as it progressed, and the number was limited to a few at the end. The outlet has almost no limit because it floats and moves the additional magnetic material. Noise is prevented because there is no mechanical movement. Figure 4-2 is a sketch of the equipment from above when placed in parallel.

In order to keep the flow line of the magnetic adduct constant, a groove below the average radius of the magnetic adduct should be installed along the flow line of the magnetic adduct on the inner wall or outer wall of the container, and the bottom of the groove must be uneven. Makes it easy to attach/detach magnetically additional materials other than the amount by vibration. In addition, baffle plates are installed on both sides of the groove to control the number of magnetic adders passing through the groove. When the container or the entire device is impacted by an external impact, a shock absorber may be installed as a measure for reducing the impact force. The number of electromagnet groups that can move and change the magnetic force is not limited to one row, but multiple rows are arranged to change the amount of current in each row, and the energization time can be set at the same time or a time difference to set the amount of any magnetic adduct. Can be weighed and transported. The material of the container is preferably 18-8 stainless steel which does not have magnetism, glass, ceramics or a material having an antistatic function.
