Therefore, the specific issues at the time of its implementation are also unknown. In the present invention, the technical summary of the catalytic combustion reaction of the liquefied gas applied to the heat sterilization device for the cutting tool for agricultural and horticultural crops and the problem of applying it to the heat sterilization device for the cutting tool for agricultural and horticultural crops are first. A heating mechanism using a gas soldering iron is briefly described as an example. A typical liquefied gas soldering iron has a basic structure comprising: a cassette for liquefied gas, an injector for mixing a liquefied gas with air to generate a mixed gas, and a piezoelectrically ignited mixture gas to generate a fire. a combustion chamber (preheating zone) for heating the catalyst, a combustion reaction catalyst for starting a catalytic combustion reaction by heating with stepwise combustion, and a heating tip; air and liquefaction from the injector The gas mixture is subjected to piezoelectric ignition to generate flaming combustion, and the high temperature of the fire is used to heat the catalyst to the starting temperature of the catalytic combustion reaction, and then the flameless complete combustion of the mixed gas by the catalyst is continuously continued. The reaction heats the heated tip to a high temperature' to thermally process the work. In the heat sterilization device for a cutting tool for agricultural and horticultural crops of the present invention, in order to use a liquefied gas as a heat source and to efficiently utilize heat obtained from a small-sized small-capacity gas cartridge, it is necessary to use a catalyst or a preliminary heating zone thereof.

Further, in such a small space, it is known that flaming combustion for preliminary heating as a front portion of the start of the touch is remarkable. For example, it has been reported that in a gas having an approximate liquefied gas, once the diameter of the combustion tube is 3 mm or less, it is difficult to carry out, and the inventors of the present invention use a liquefied gas (the experiment of Dingda is also considered to have the same tendency. Other actual welding) During the operation, the conditions such as the air pressure/fuel ratio pressure may be repeated several times. The piezoelectric point starts to be flaming and the catalyst starts to react, so that the catalyst starts the combustion reaction, which may not be sure. The purpose of the heat treatment is to confirm whether the sterilization has been completely sterilized by heating in the heat sterilization operation of the cutting tool for the horticultural plant of the pathogenic microorganism. The use of the cutting tool in the state of the non-heated state of the false medium has been mistakenly When the object is cut and the operation is continued without paying attention to the pathogenic microorganism attached to the knife, even if the chance is extremely low, the significant result of the infection of the garden or the house is the subject of the present invention. In the heat sterilization apparatus for art crops, when the liquefied gas as a heat source is heat-sterilized by burning the tip end of the blade, it can be obtained by liquid burning. When the heat of combustion is effectively transmitted to become a heating pair, because a package is buried in the middle limit, such a combustion reaction of the medium is unstable, and the flame combustion becomes t gas, and the temperature and the external fire operation are fired. When the bacterium is in the hair, it is impossible to create a situation in which the front end of the blade that is exposed to the infection is infected. The catalyst of the cutting tool reacts to the front of the blade of the burning of the combustion gas to increase the utilization efficiency of the limited heat obtained from the cartridge of the liquefied gas. Another object of the present invention is to provide a configuration in which the catalytic combustion reaction of the catalyst can be surely performed so that the heat sterilization is completed completely. Still another object of the present invention is to provide a heat sterilization device for a cutting tool for agricultural and horticultural crops which is small, lightweight, and easy to handle, and which does not substantially change the structure of a conventional cutting blade for agriculture and gardening. [Technical method for solving the problem] The above-described problem is basically based on a heating and sterilizing device for a cutting tool for agricultural and horticultural crops based on a catalytic combustion method of a liquefied gas, in which an electrothermal heating wire is used in order to start the catalytic combustion reaction. Instead of the flaming combustion caused by the piezoelectric ignition of a gas which is generally used for a gas soldering iron or the like, the mixed gas is heated. That is, the "heat sterilization of the cutting tool for agricultural and horticultural crops of the present invention" has a gripping action in which the tip end portion of the blade is provided on the tip end side, and the catalyst combustion reaction using the liquefied gas as a heat source is the blade end. The portion is thermally sterilized, and the grip portion has therein: a liquefied gas tank; a flow rate control valve for liquefied gas discharged from the gas tank; and an 射IL speed of the ejector gas controlled by the flow rate control valve The air is sucked from the outside to generate a mixed gas, and the tip end portion of the blade has therein: a 'combined gas flow path that communicates with the injector and is inside the tip end portion of the blade.卩 is extended toward the front end side along the flow direction of the mixed gas; 201249331 is supplied with gas heating along the mixed power supply unit; the pre-heated mixed combustion reaction of the combustion reversely forms the thin tube of the present invention, and the gas flows therethrough Metal fine media. The external system for firing the outer tube of the present invention has heat storage from the wire of the present invention from the groove. The heating wire of the present invention is composed of a hot wire, and covers the entire hot zone, and is composed of an electric heating wire. Further, the heat is generated by the electric power inside, and the inside of the mixed gas flow path and the catalyst are accommodated in the downstream side of the heating path of the mixed gas flow path. After the catalyst combustion reaction is performed, the front end portion of the blade is heated by the combustion of the mixed gas. In a preferred aspect of the present invention, the mixed gas flow path is formed by the metal thin tube in a groove that is inserted in a direction along a front end surface of the blade, and is configured to provide the electric heating wire and the combustion in the mixed gas flow tube. On the other hand, in a preferred aspect, the inner wall surface of the groove and the surface have a dioxate inflow path formed along the longitudinal direction of the groove, and a gap flows between the outer cover flowing to the inflow path and the front end surface of the blade. , # side of the vent hole out. In a preferred embodiment, the electrothermal and electrically insulating ceramics of the preheating zone are coated. Fortunately, in the preferred embodiment, the flow direction of the /Q mixed gas in the preliminary heating zone is wound into a spiral force. The hot wire of the spiral is mixed with the inner wire by the electrically insulating and heat storage ceramic hot wire holding portion. The metal is mixed, and the metal gas is contacted and heated from the heated ceramics. -10- 201249331 In a preferred aspect of the invention, the foregoing catalyst is formed to form a coating layer of platinum particles on both sides of the substrate. A combustion zone as a catalyst.

The grip portion 2 is formed in a shape of -14-201249331, and a card 4 is accommodated in the inside. Liquefied gas is only used in Cao 4 曰wm hole body slot ·", Xiaoban I butane/propane gas cartridge, with refill filling, valve 4B and haiku section & / Α and On the flow side where the discharge flow rate is controlled, a downstream outlet 5 for generating a liquid liquefied gas tank 4 is provided. The injection body of the mixed gas with the external air is taken in, and the second gas is connected to the external air path provided on the cylindrical surface of the grip portion 2. The supply of the mixed gas flow is communicated with the tip end portion 3 of the blade. There is a DC current that supplies power to the electrothermal heating wire 9 to be described later. For example, a rechargeable small-sized secondary battery is incorporated in the grip portion 2 as a power supply portion. As shown in Fig. 3, in the right side of the tip end portion of the blade, there is a groove 7 on the upstream side (left side in the drawing) to the downstream side (Fig.::) 7 on the side of the injector 6 In the surface of the blade tip end portion 3, a metal thin tube 8 as a mixed gas flow path is fitted, and a μ metal thin tube 8 communicates with the tip end side of the groove 7 of the emitter 5, and a lower edge in the metal thin tube 8 Month "And." Burning Reaction Catalyst '10. On the most downstream side, as shown in Figure :: Exhaust gas discharge after the combustion reaction of the catalyst with the combustion gas on the side is formed with a mixed heat line 9 along the metal The inside of the thin tube 8 is inserted, and the groove 7 is electrically heated and twisted. As shown in Fig. 2, the heating line is spirally covered by the groove, and The heat storage m is used to cover the kiln winding 庳觫#1Λ to form a preliminary heating zone 9Α for the combustion reaction catalyst 10. The groove 7 is connected to the _ pole of the power supply unit 6 at the end of the addition side, '' 7' ' is connected to the other -15-201249331 pole of the braiding, winding, and electric parts 6 on the migration side via the metal conductive portion of the blade tip end 3. The combustion reaction catalyst is provided on the downstream side of the electrothermal heating line 9. 10, the combustion reaction catalyst 10 is composed of fine particles of platinum supported on a sheet-shaped stainless steel substrate. As shown in Fig. 3, the combustion reaction catalyst 10 is kept at a predetermined temperature for maintaining the entire temperature of the blade tip end portion 3. Above the sterilization temperature, it has a sufficiently effective surface area, and a cross-sectional shape with respect to the flow direction of the mixed gas forms a wave shape so that the mixed gas of each part of the gas flow path is rectified to be in effective contact with the reaction zone of the catalyst. The metal thin tube 8 in which the electric heating wire 9 is housed is housed in the groove 7 provided at the tip end portion 3 of the blade, and the groove 7 is closed by the groove cover 7A to be solidified. 'The inner wall surface and the outer peripheral surface of the metal thin tube 8' form useful The flow path L for the secondary combustion for improving the combustion efficiency is connected to the exhaust port 下游 on the downstream side of the catalyst 2〇. The groove cover 7a is attached to the front end of the blade. The surface of 3 has only a small gap G, and the external air sucked from the gap G is ejected to the exhaust hole H by the flow path L, and when the unburned liquefied gas component remains in the exhaust gas caused by the combustion of the catalyst, the aforementioned The attracting external gas (oxygen enthalpy) reacts with it to cause secondary combustion. The groove cover 7 引 of the 卩3 Α3 and the metal fine e 8 accommodated in the groove 7 correspond to the combustion reaction catalyst 10 In the portion, the confirmation hole 7 B for confirming the reaction state (red hot state) in the combustion reaction catalyst and the 10 $ combustion reaction operation is formed. When the heat sterilization device for the cutting tool for agricultural and horticultural crops is used, the switch (not shown) of the power supply unit (battery) 6 is turned on, and the current from the battery 6 is applied to the electric heat in the metal thin tube 8 as the gas flow path - 16 - 201249331 The hot wire 9 is supplied with power and heated, and the metal thin tube 8 as a gas flow path is buried in the groove 7 formed at the tip end portion 3 of the blade. The mixture & gas & will be cooled by vaporization of the liquefied gas, and will not be heated to a predetermined temperature in a short time when the heating coil 9 is heated. In the specific example, (4) the preliminary heating zone 9A formed by coating the electric heating heating wire 9 with the ceramic 1 is disposed close to the catalyst 1〇, so the heat generated from the electric heating wire 9 is stored in the ceramic coating layer, and the ignition switch is turned on. After (ON), a sufficient amount of heat is accumulated in the ceramic covering for a short time. After a predetermined short period of time, the adjustment knob 4C of the flow f valve 4B attached to the liquefied gas tank 4 is rotated to discharge the liquefied gas at a predetermined initial flow rate, and is mixed with the outside air in the inside of the injector 5 to generate a mixed gas, which is supplied to the mixture. The preliminary heating zone 9A of the heating wire 7 in the aforementioned metal thin tube 8. When the mixed gas passes through the preliminary heating zone 9A, in addition to the heat generated from the electric heating wire 9, it is heated by the heat accumulated in the ceramic covering to be sufficient to heat the catalyst 10 to the reaction starting temperature or higher. temperature. If the combustion reaction catalyst is heated to a temperature exceeding the starting temperature of the combustion reaction, the catalyst 1 will itself start flameless combustion due to the combustion reaction. After confirming the red hot state of the catalyst by confirming the hole 1 7 B, the flow rate of the mixed gas is increased to the flow rate (ignition switch OFF (OFF)) necessary for heat sterilization, and then the combustion reaction catalyst 10 is continued at the predetermined combustion temperature. The flameless combustion reaction of the mixed gas heats the entire tip end portion 3 to a sufficient temperature required for heat sterilization of the microorganisms. At this time, as shown in Fig. 3, the 'mixed gas system' flows through the flow path divided by the mountain portion and the valley portion, which are formed into a waveform (μ-type), so that the mixed gas and the catalyst are mixed. The contact area of 10 0 is increased, and the gas flow of each part is rectified, and the reaction efficiency is improved. -17- 201249331 Measurer 1 排气 The exhaust gas of the mixed gas after combustion is discharged from the vent hole. However, after the vent port, the feed is sucked from the gap G of the groove 7 shown in Fig. 3 and The external air that has flowed through the flow path L further burns the unburned components in the exhaust gas to improve the combustion efficiency of the liquefied gas, and further increases the heating temperature of the blade tip end portion 3. In the heat sterilization setting of the cutting tool for agricultural and horticultural crops of the present embodiment, the combustion reaction catalyst 1 is heated to the combustion reaction start temperature and the preliminary heating is performed by the metal thin tube 8 as the mixed gas flow path. The mixed rolled body is heated by the electric heating wire 9 and is surely carried out, and the catalyst combustion reaction does occur at the beginning. As described above, the preheating of the mixed gas proceeds to the flameless combustion by the catalytic combustion reaction, that is, the ignition stability when the combustion reaction catalyst starts to be burned, and is cut off for the agricultural and horticultural crops as described above. The heat sterilization device of the tool is particularly important. In the present invention, since the continuous feeding electric heating wire 9 from the power supply unit 6 generates heat and the mixed gas is constantly heated, the ignition switch is turned on for a fixed time at the start of the operation, and the heating by the mixed gas is surely enabled. When the catalyst reaches the starting temperature of the combustion reaction, the combustion of the catalyst is completely ignited by the combustion reaction of the catalyst, and the blade end portion 3 can be often heated and sterilized. From the step of using the soldering iron X of the conventional piezoelectric ignition method, it is difficult to construct the thin blade front end portion 3 such as the preparatory heating zone (the (four) firing chamber) or its supporting mechanism. As long as the metal thin tube 8 is inserted into the groove through which the metal thin tube 8 is placed along the tip end portion η of the blade, and the inside of the heating gas mixture is installed, the px /*» of the medium is installed. Bright side heat • 18 - 201249331 Heating line 9, and this can be used, so it can be in the shape or shape of the lower part 3. The combustion reaction catalyst I for flameless combustion is the knife that has not changed the conventional cutting tool.

Description of the embodiments. In Fig. 4, the pair of gripping portions 12, u and the blade tip end portions 13, 13 are used for the cutting tool of the cutting tool used for cutting, picking, and cutting of a general agricultural and horticultural crop. In the configuration, one of the holding portions 12 in the lower portion of the figure has a grip portion 12 on the middle of the middle of the cassette containing the liquefied gas, and is substantially flat, and is on the front side -19-201249331 side. The front end portion 13 of the knife is made of conductivity/heat transfer. A pair of knife tip ends 13 are joined. 1 3 connection & warfare body, at least the front end of the blade is good. ^^There is a metal material such as steel. 1 3 is elastically rotated by the bullet_sponsoring member S. The cassette box used in this embodiment is 14 inches. It is a group of butane/propane, 4 5 〇 mm X 25 mm (p scale, '' is more than 9 〇: 1 〇, and is used to transfer the liquefied gas of the knife to the temperature required for the pressurized temperature. Constantly heated to 90 Τ: the base end of the above 14 is provided with gas, main, 々9... The cassette is provided with a flow control of the effluent gas 'Λ valve 14A' and the front end... cassette 1... :=Γ. The holding valve 14 裂 is inserted into the lower holding valve 14 to perform the rotation operation to match the opening == 乍, and the flow rate of the liquefied gas can be controlled by controlling the flow rate, etc. The flow rate of the gripping portion 12 and the bugging side are provided. The flow rate of the liquefied gas ejected from the card tray 14 is sucked and the external gas is mixed and the injector 15 is mixed. In response to the liquefied gas, the suction hole 15 is attracted to the outside. The gas and the liquefied gas m' generate air/fuel which is most suitable for the combustion of the combustion reaction catalyst described later. a mixture of gas (31: ! molar ratio). The downstream side of the injector 15 is provided with a metal capillary tube as a mixed gas flow path through the hollow portion of the grip portion 12 to the end portion 13 of the blade edge. (Outer diameter 3ηιηιφ) Further, the aforementioned grip portion 丨2 is provided with a pair of power receiving terminals 'having a lead wire connected to an external power source as a power supply portion 16 for supplying a heating current to the electric heating heater wire 19. The actual use of the portion In the experimental example, the power supply wire of the Li secondary battery (not shown) carried by the operator is connected to the power receiving terminal. -20- 201249331 As shown in Figs. 3 and 4, the blade 11 is cut. The blade tip end portion 13 is formed with a groove 17 having a width of 4 mm and a depth of 3 mm along the longitudinal direction of the tip end of the blade (flow direction of the mixed gas), and an emitter from the grip portion 1 2 is embedded therein. The metal thin tube 18 of the mixed gas flow path on the downstream side of the first side. The metal thin tube 18 and the groove 1 7 are covered by the groove cover 1 7 A, and are fixed to the side of the blade tip end portion 13 by screws or the like, for example, as shown in Fig. 3. As shown, the metal thin tube 18 will be closed when the opening is closed by the groove cover 1 7 A. The pressurization is formed into a slightly flattened shape and is fixed to the wall surface of the groove 17 to be fixed. However, at this time, the inner wall surface of the groove 17 and the outer peripheral surface of the metal thin tube 18 form a flow path L of the external air for secondary combustion to be described later. The external air for secondary combustion is sucked into the flow path L through the mounting gap G of the groove cover 17A with respect to the blade tip end portion 1 3 A, and the downstream end portion of the flow path L communicates with the exhaust gas from the catalyst 20 The vicinity of the discharge port is inserted into the metal capillary tube 18 in the tip end portion 13 of the blade, and the electric heating wire 19 is inserted. Here, one end of the heater wire 19 is connected to the wire coated with the heat-reducing polyimide. As the one polarity end 16 6 A of the power receiving terminal 16 of the power supply portion, the other end of the electric heating wire 19 is connected to the metal thin tube 18, and is connected to the other terminal of the power receiving terminal 16 via the conductive portion of the blade tip end portion 13. Polar end 1 6 B. Thereby, a wire is omitted, and the wiring in the metal capillary tube 18 is simplified into a single-line form, and the limited storage space of the metal capillary tube 18 can be effectively utilized. The electrothermal heating wire 1 9 is formed by winding a nickel-chromium alloy (NCH) or iron-chromium alloy (FCH) heating wire of about 0.1 5 mm φ into a coil shape of about 1.5 mm in shape, using heat storage and electrical insulation. The immersion coating of the ceramic slurry forms the preliminary heating zone 19A shown in Fig. 2. -21 - 201249331 The downstream side of the electric heating wire 丨9 of the metal clerk 1 (the front end side of the blade) is arranged to be burned The reaction catalyst 20. The combustion reaction catalyst 2 is a stainless steel metal box having excellent heat resistance as a support, and a heat-resistant ceramic having a large specific surface area, that is, alumina, is formed on both surfaces thereof as a carrier substrate for increasing the reaction area. Here, the platinum group metal or the alloy fine particles are supported in a highly dispersed state to form a heat-resistant combustion reaction catalyst. As shown in Fig. 3, the cross section of the catalyst 20 with respect to the flow direction of the mixed gas forms a wave pattern). The contact area of the mixed gas is increased, and the flow path of the mixed gas is uniformly rectified in each region divided by the respective waveforms, so that the reaction efficiency can be increased. As the platinum catalyst 2 燃烧 of the combustion reaction catalyst 20, the catalyst reaches a temperature of about 1 85 ° C as the mixed gas is heated by the heat generation of the preliminary heating zone 丨 9 A composed of the electric heating wire 19 The combustion starts the reaction temperature, and the combustion reaction is started. Thereafter, the combustion gas of the butadiene/propane is completely flamelessly combusted by its own catalyst combustion reaction. In the above-described experimental example of the present invention, an external battery (not shown) is connected to a power receiving terminal provided as a power feeding portion 16 of the grip portion 12, and an ignition switch (not shown) is turned on. Thereby, the electrothermal heating wire 19 is heated to accumulate sufficient heat for a predetermined short period of time in the ceramic coating layer of the preliminary heating zone 19A which is formed by the spiral of the most downstream of the catalyst 20. Here, an appropriate amount of liquefied gas is ejected by the flow rate control valve 14B to generate a mixed gas, and is supplied to the preliminary heating zone 19A through the metal capillary 18 as a gas flow path. Here, the heated mixed gas contacts and flows with the downstream combustion reaction catalyst 2, whereby when the combustion reaction catalyst 2 is heated to the start temperature of the catalytic combustion reaction of -22-201249331 Above (1 8 5 °C), the catalyst combustion reaction will begin. After confirming the thermal state of the hole 1 9 A, the flow control valve 14B is rotated to make the gas flow predetermined. Thereafter, the combustion reaction catalyst 20 heats the entire blade tip end portion 13 in which the catalyst 20 is buried to the upper 0 mixed gas passing through the catalyst by the catalytic combustion of the mixed medium for a temperature of about 7 ° C or higher. In the case of 1 〇, the high combustion efficiency is the exhausting order after combustion in the vicinity of the vent hole, and the undesired component (butane) is still contained. In this embodiment, 'butane which flows out of the high-temperature exhaust gas after the external gas sucked from the groove cover and flows out to the discharge hole by the flow path L is reburned by the external oxygen, and the combustion can be further improved. effectiveness. In the case where the scissors 'closes the flow path of the secondary air, the temperature around the vent hole of the blade rises by about 30 to 50 °C. As long as the supply of the mixed gas from the cartridge 14 is supplied, the combustion reaction can be continued, and the cutting edge portion 13 can be maintained at the high temperature in the agricultural and horticultural processing, and the bacteria can be surely infiltrated even if pathogenic microorganisms adhere. In a short time or extinction 'prevent infection from spreading to the periphery. The tip end of the knife can be confirmed by confirming the red hot state and the discharge sound of the catalyst by the confirmation hole 17B. The scissors for cutting in the present embodiment are similar to the case of the embodiment shown in Fig. 1, and the structure is greatly simplified even if the heat sterilization device is provided. That is, 'compared with the conventional catalyst 20 to confirm that the red amount is increased to the gas contact reaction' at about 90 ° C to burn, but the burning gap G Η is the front end of the blade in the example of the gas. During the period of the catalyst, the heating is performed to make it deactivate the heating state. The gas is basically not used by the heating mechanism of the piezoelectric point -23-201249331 fire type catalyst combustion reaction, and the piezoelectricity can be omitted. The metal capillary tube, the electric heating wire, and the combustion reverse heating mechanism, which are the combustion chamber for combustion or the baffle attached to the combustion chamber, are accommodated in the groove which is inserted at the tip end portion of the blade, and are significantly simplified. The manufacturing cost of the cutting knife can be reduced, and the conventional male knife can be easily used in the same operation. Further, in the above-described embodiment, the configuration of the mixed gas flow path is provided only in the front end portion 13 of the upper end of the blade in the upper end of the blade, but the front end portion of the two blades can be formed. A gas flow path is provided and heated. In this case, the metal thin tube as the mixed gas flow path may be branched in the middle, and a flexible metal tube or the like may be used around the branch portion, and a branched metal thin tube (gas flow) may be formed at the other end portion 13 road). [Test Example] Using the scissors in the above experimental example of heating the cutting tool for agricultural and horticultural crops of the present invention, the following test was carried out to demonstrate the heat sterilization effect of the crop. The adjustment of the test bacterial solution was carried out by shaking the culture medium of the B. solani 30-2 strain in the liquid medium of the genus, and shaking culture at 100 rpm for 16 hours, and adjusting the bacterial liquid to 1 X 1 〇 6 cells/ml °. The cloth is assembled on the end of each blade of the two scissors, and a pair of scissors is energized by the electric heating wire 3 to heat the front end portion of the knife to 9 inches. 〇 'and the other scissors are caused by k' and act as a catalyst. This structure is combined with P 13 (the first heating and mixing): before the splitting knife, the sterilization equipment is about 27 ° C. In the case of the non-heating -24-201249331 state, the leaves of the third leaf and the fourth leaf petal of the 〇 苗 苗 (P〇nderosa, the height of the aboveground height of about 4 〇 cm) were continuously cut into two pieces. After the inoculation, the squash seedlings were managed in the greenhouse, and they were managed in the glazing room. After the vaccination date, they were double-checked for morbidity. Among the unheated sputum strains, 9 of them were found to have the disease (atrophic condition). In the case of the squid treated with the scissors heated to 9 ,, no disease was observed at all, and it was confirmed that the heating of the tip end portion of the scissors was extremely effective in sterilizing the bacterial wilt. Stem of tomato seedlings with atrophic symptoms (confirmed by the outflow of bacteria), using heated scissors at the tip of the knife, unheated boring knife, and sub-bubble aqueous solution of calcium sulfite as a disinfectant (diluted seven) Scissors, each cut off the times, and then cut off the healthy Jiatian (Ponderosa, the height of the ground is about 4 〇cm) 15 strains and eggplant seedlings (thousands *, the height of the ground is about 40 cm) 10 of the leaves of the third leaf and the fourth ', the petiole base, for the cutting treatment 20 In the future, each seedling was examined for the onset of bacterial wilt. Among the 15 tomato seedlings after the treatment, it was confirmed that one of the heated scissors was the onset of lupus, and that none of the unheated scissors were There are 5 unheated scissors treated with sodium hypogas sulphate for the incidence of green disease. Take 10 strains of eggplant seedlings, and confirm that there are i strains in the heated scissors.枯病杂# j. X rain, unheated scissors, 1 〇 all of them are the pathogen of bacterial wilt, and 5 of the unheated scissors treated by human sodium chlorite are the onset of bacterial wilt. -25- 201249331 In the cutting operation of the unheated scissors, it is considered that all of the infections occurred. On the other hand, the heated scissors of the present invention confirmed that the infection-inhibiting effect was excellent. Further, some causes of infection were considered to be due to the present. The scissors of the experimental example of the invention only heat the front end of a blade (one plus The temperature of the hot blade is 95 °C, and the temperature of the other blade is 6〇.〇), but the infection rate is significantly lower than in the case of chemical treatment. As mentioned above, it is considered that another cutting blade by scissors The same heating means is provided, or the amount of the mixed gas from the gas cartridge side or the amount of heat generated by the electric heating wire is increased, or the shape of the tip end of the blade is further reduced, and the temperature of the tip end portion of the other blade is further increased. Highly, the effect of prevention of infection can be further improved. [Industrial use possibility] The heat sterilization device for cutting tools for agricultural and horticultural crops of the present invention can be applied to various forms such as scissors, knives, kitchen knives, sickles, and the like. In the case of the cutting tool, the sterilizing method is a heat sterilization method, and it is possible to reliably prevent the spread of infection which can occur in various agricultural operations such as crops: two branches and fruit picking, in accordance with a wide range of pathogenic microorganisms.
