Description

[0001] The present invention relates to an apparatus for removing a magnetron,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a grinder removing apparatus using a magnetron, and more particularly, to a grinder removing apparatus using a magnetron for irradiating microwaves to cause damage to trees.

As shown in Fig. 1, it grows well in any place where the sunlight is well, and is distributed in Japan, China, Southeast Asia, etc. . It is a perennial herbaceous tree. Its stem ends dry in the winter, but the lower part is lignified. The roots stretch sideways in the ground and store starch.

Once the roots are removed, they will cover a 15-meter radius within a year or two, so that if they are not removed, they will cover the top of the tree so that the tree does not die or hides the tree so it does not grow. One 차지 occupies an area of several tens of square meters and damages it, which can devastate the mountain. In addition, when the tree trunk is wrapped around the tree, the tree itself is bent and the value of the wood is lowered, and the tree is weakened by the tree, and the tree is easily broken into the wind.

Therefore, as shown in FIGS. 2 to 3, attempts are made to solve the problem by various methods such as a manual method, a mechanical method, and a chemical treatment method.

However, it is most desirable to remove the root, but it is not easy to draw roots that extend over 2m deep. Also, there is currently no physical removal equipment available to remove scratches. In other words, in order to remove the sawdust using physical equipment such as a shovel, a hoe, or a saw, it is necessary to completely expose the sawtooth in the soil and then cut it with a saw, We use herbicides, but we have to repeat them a few times and a lot of people have to be mobilized to remove them.

Currently, there are various methods of using the drug to test the pain, and as a representative form, a drug injection method using a syringe and a drug application method using a brush are introduced.

In the drug injecting method using a syringe, a drug is injected in a scanning manner. As disclosed in Utility Model Publication Nos. 1990-0000271 and 1996-0004021, in order to inject a drug into a syringe, The same sharp tool is used to puncture the 칡, insert the needle of the syringe into the hole, insert the drug into the syringe through the syringe, and then the drug penetrates into the 칡 and breaks the 칡.

A method of applying a drug using a brush is a method that is used in conjunction with the development of a new drug. When the drug is applied to a surface of a brush by putting the drug into a predetermined container, It is a method to infiltrate into the inside of the 칡 and end the..

However, in the method using the above-described syringe, since a predetermined hole is first made in the syringe every time the syringe is removed, the needle of the syringe is inserted into the syringe and the drug is injected into the hole, .

In addition, the method using the brush has disadvantages in that it is necessary to separately provide a container containing a drug and a brush for applying a drug, and the container has an opening of a predetermined size for taking a drug, The user may be injured by a toxic drug which causes the malodor generated from the toxic drug to leach out to harm the health of the worker and the drug is tilted by the carelessness of the user, .

In order to solve these problems, Patent Registration No. 10-1207285 and Utility Model Registration No. 20-0134606 have been proposed. However, since the roots of the roots are still exposed to the soil, it is necessary to remove the roots spread over a wide area There are still many problems such as the need for a lot of manpower and the contamination of nearby plants and drinking water due to the use of drugs.

Therefore, the above techniques required a lot of manpower to take charge of a large area, took a long time, and it was not easy to remove due to a lump around the root. There was a risk of pollution to the surrounding environment during the treatment with the drug, and there was a limit in handling large amounts of vinyl during the vinyl treatment, and when machinery such as a saw or grass cutter was used, there was a high risk of injury due to fragmentation .

Korean Utility Model Publication No. 1990-0000271, entitled " Korean Utility Model Publication No. 1996-0004021, entitled " Korean Patent Registration No. 10-1207285, entitled " Injector for Drug Disinfection " Korean Utility Model Registration No. 20-0134606, entitled "Drug Application Type"

[

Hereinafter, an apparatus for removing a magnetron using a magnetron according to an embodiment of the present invention will be described as follows.

As shown in FIG. 5, the magnetron removing apparatus according to the embodiment of the present invention includes a magnetron 110 for generating a microwave; A waveguide 120 installed at one side of the magnetron 110 and formed of a hollow square metal tube as a microwave transmission path generated by the magnetron 110; A horn-type radiation part 130 provided below the waveguide 120 and irradiating a microwave to an opened lower part; And a blocking cover 140 covering the lower edge of the radiating part 130 and covering the lower part of the radiating part 130 to block the emission of the microwave to the outside of the gap between the lower part of the radiating part and the uneven surface.

In addition, moisture contained in the soil or air flows into the waveguide 120 through the radiation part 130 to prevent water from being formed and malfunctioning of the electronic device at the interface between the waveguide 120 and the radiation part 130 A Teflon film 150 for blocking water inflow is inserted.

A cooling fan 160 for cooling the heat generated by the magnetron 110 or the waveguide 120 may be installed at one side of the magnetron 110 or the waveguide 120.

A grasping portion 170 fastened to a moving means (not shown) or held by a human hand can be mounted on one side of the magnetron 110 or waveguide.

The apparatus for removing magnetism using the magnetron according to an embodiment of the present invention includes a power generator 20 for supplying power to the magnetron 110 and a magnetron 110 for controlling the magnetron 110 by an emergency stop The control device 30 may be further included.

Meanwhile, the magnetron removing device using the magnetron according to the embodiment of the present invention can be moved by the hand of a person, and can be operated while being moved using a moving means (not shown) if necessary.

As a means of transportation, there are generally used tillers working mainly for rotary tillage, tillers for towing of plows or trailers, management machines for working soil between paddies, or plows for farmland construction or deep cultivation A tractor or the like, which is used to tow a vehicle, and all the mechanical equipment that carries an engine, a motor, a movable drive device, or the like that generates power or belongs to a moving means.

The structure of the magnet removal apparatus using the magnetron according to the embodiment of the present invention will be described below.

The microwave generator 10 includes a microwave generator 10 for generating microwaves and a microwave for generating and removing microwaves. The microwave generator 10 includes a magnetron removing device 10 according to an embodiment of the present invention, Can be implemented.

The power generation apparatus 20 is an apparatus for supplying electricity to the microwave generation apparatus 10, and may be replaced with a power supply unit mounted on the moving means or an electric supply source capable of supplying electricity from the outside.

The control device 30 functions to operate and control the microwave generator 10 by an emergency stop, automatic stop, power on / off, automatic control using a timer, and the like.

Next, the specific configuration of the microwave generator 10 is as follows.

The magnetron 110 is a special vacuum tube for controlling the flow of electrons by applying a magnetic field in a block shape to output or generate a microwave.

For reference, a microwave is a term that refers to all radio waves with a wavelength range of 1 mm to 1 m. Because of its short wavelength, it has almost the same properties as light, has strong sterilizing power, absorbs well in plants and water, and generates heat. If the electromagnetic wave is classified according to the frequency, it is called a submillimeter wave of 30 to 300 kHz for a long wave, 300 to 3,000 kHz for a medium wave, 3,000 to 3 GHz to 30 GHz for a centimeter wave, 30 to 300 GHz for a millimeter wave and 300 GHz or more for a submillimeter wave. Among them, electromagnetic waves from 300 MHz to 30 GHz are called microwave. When a wavelength is short like a microwave, it has a property similar to a light wave, and has a property of rectilinear reflection, reflection and absorption. Therefore, besides being widely used for communication (transmission of radio waves), it is used for heating of food by microwave dielectric heating, thawing of frozen food, simple sterilization of food, sterilization of insect pest in food.

In addition, a magnetron is also called a magnetron tube. It was invented by AW Hull in the United States in 1921. An electrode of pure copper is used as an anode, and a cathode and a grid are disposed in an axial direction. When a magnetic field is applied in the axial direction of the cathode, the electrons protruding in the radial direction from the cathode are attracted to the anode and at the same time, they are subjected to a force perpendicular to the traveling direction by the magnetic field. As a result, the electrons make spiral motion. Here, when the intensity of the magnetic field is increased, the amount of bending of the electrons is increased, and the bending of the electrons is repeated several times before reaching the anode. When the strength of the magnetic field reaches a certain limit (critical magnetic flux density), the electrons hardly reach the anode. At this time, around the cathode, a rotating electric pole is generated by electrons, and an induced current (induced current) is generated in the vibration circuit of the anode, so that the vibration is stimulated. The oscillation frequency is mostly determined by the oscillation circuit and is highly efficient, and also the large output is obtained. It is widely used in industrial applications such as high frequency heating, particle accelerators, radar, and home appliances such as microwave ovens.

The waveguide 120 may be a microwave transmission path having a hollow metal pipe whose inner intervals are parallel to each other, and the cross-sectional shape of the waveguide 120 may be a square or a circle. In microwave, waveguides have much fewer losses (resistive, radiative, and dielectric) than parallel two-wire or coaxial cables and can deliver much greater power than coaxial cables of the same dimensions.

Therefore, the waveguide 120 is a circular or square linear tube, and the microwave oscillated by the operation of the magnetron 110 passes through the inside of the waveguide 120 and enters the radiation part 130, which will be described later, It converges without spreading.

However, the waveguide 120 may be a waveguide (not shown) connected to the upper portion of the radiation portion 130 so that the gap between the waveguide 120 is dispersed when the microwave is oscillated from the antenna of the magnetron 110, 120 can be formed in a trapezoidal shape that widens gently.

As shown in FIG. 5, the waveguide 120 has a rectangular shape, but it is not limited thereto, and it is natural that the waveguide 120 can be formed into a circular shape, an elliptical shape, or a polygonal shape, if necessary.

The radiating part 130 is a horn type opening up and down. The radiating part 130 serves as an outlet for emitting a microwave incident from the waveguide 120 by a trapezoidal tube whose upper part is narrower and wider downward. The radiation unit 130 is coupled in the same direction as the waveguide 120 as shown in FIG.

As a result, the microwaves oscillated by the operation of the magnetron 110 are focused until they pass through the inside of the waveguide 120 and are incident on the radiation unit 130, and are emitted to the open outlet of the radiation unit 130, The area to be irradiated and the range to be irradiated are enlarged and microwaves are widely dispersed within the open outlet range of the radiation part 130.

In this case, the microwave returns to the traveling wave and the reflected wave in the radiation part 130. The microwave is emitted through the radiation part 130, which is opened at the lower part, to be irradiated to the ground. At this time, .

The blocking cover portion 140 is made of a metal material of a flexible mesh structure having a predetermined weight for preventing microwaves from being transmitted therethrough. The material may be steel.

The blocking cover 140 is installed downward along the lower edge or edge of the radiation portion 130 to prevent the microwave from being emitted outside the gap between the lower portion of the radiation portion and the uneven surface, (Soil) without escaping to the outside of the lower clearance of the ground surface (soil).

Particularly, the blocking cover portion 140 can be adhered to the surface of the uneven soil due to the flexible and flexible mesh material having a predetermined weight, and the resistance can be minimized even when the blocking cover portion 140 is moved using the moving means have.

The Teflon film 150 is inserted into the interface between the waveguide 120 and the radiation unit 130 so that the moisture contained in the soil or the air flows into the waveguide 120 through the radiation unit 130, To prevent malfunctions. Teflon is used to shield microwaves but not water.

In addition, the Teflon film 150 prevents the open bottom of the waveguide 120 from being exposed to the outside, thereby preventing foreign matter from entering the inside of the waveguide 120 through the opened radiating part 130.

The cooling fan 160 is installed at one side of the magnetron 110 or the waveguide 120 to cool the heat generated from the magnetron 110 or the adjacent waveguide 120.

The grasping portion 170 is mounted on one side of the magnetron 110 or the waveguide 120 and serves as a handle to be fastened to a moving means (not shown) or to be held by a human hand.

FIG.

An apparatus using the magnetron removing apparatus according to an embodiment of the present invention constructed as described above operates as follows.

A microwave generator 10 having a magnetron with a capacity of 1 kW, a power generator 20 having a capacity of 2 kW, and a controller 30 for controlling the microwave generator are prepared for operation.

The control device 30 turns on the power supplied from the power generation device 20.

When electricity is supplied to the microwave generator 10, the magnetron 110 is operated.

The microwaves are oscillated in the magnetron 110, and the oscillated microwaves are incident on the waveguide 120.

The incident microwaves pass through the waveguide 120, the Teflon film 150 for blocking moisture, and propagate to the radiation part 130.

At this time, the tape-lawn film 150 blocks the moisture contained in the soil or the air that causes the microwave to pass through but causes the malfunction of the electronic device.

The microwave incident on the radiation part 130 is emitted to the lower part of the radiation part 130 and is irradiated to the light to be removed.

At this time, the blocking lid part 140 is installed to extend along the lower edge of the radiation part 130, so that the microwave irradiated is prevented from being released between the lower part of the radiation part 130 and the soil surface gaps, Irradiation). In addition, since the blocking lid 140 is mounted on the lower edge of the radiation part 130, the microwave can be exposed to an operator in the vicinity, thereby securing safety.

When the irradiation operation for the object to be removed is completed, the grasping portion 170 mounted on one side of the waveguide 120 is held by the human hand and moved to the next irradiation site. Alternatively, if necessary, the grasping portion 170 of the grinder using the magnetron according to the present invention may be tightened to the moving means and irradiated toward the grinder while moving.

Since the microwaves oscillated in the magnetron 110 are exposed to the object to be removed through the horn-type radiation part 130 using the characteristic that the microwaves are absorbed well in plants and water, And then heated. As a result, the stem or root of the heated 칡 is disappeared due to its loss of function and difficulty in supplying nutrients, and the sleeping or insect pests around the root are also removed.

6 and 7, it can be seen that the present invention is in the process of being practiced through actual photographs of an example of the apparatus for removing the magnetron using the magnetron according to the embodiment of the present invention, Device can be visually recognized.

As a result, it was found that there was no significant difference compared to the seeds in which the microwave was not irradiated.

Next, when irradiating the object to be removed with the magnetron removing apparatus using the magnetron according to the embodiment of the present invention, as shown in FIG. 12, the object was slightly worn on the 1st day after the irradiation, It is showing a distinctive appearance in the work.

13 is a photograph of an example of a shield cover part material used in a magnet removal apparatus using a magnetron according to an embodiment of the present invention. The shield cover part 140 includes a stretchable dense mesh network The mesh is made of a metal material. The mesh is very narrow and has a fine meshed structure that is closely fitted with a diameter of 1 mm or less so that the microwave can not pass through.

Therefore, it is possible to adhere to the surface of the uneven soil, thereby preventing the microwave from being exposed to a portion other than the portion to be irradiated.
