It can be interpreted as belonging to the scope of the present invention.

Again, if the method, which is an efficient agricultural machine repair method specialized for the agricultural machinery (hereinafter referred to as the present agricultural machinery (A)), will be described in detail for each part, the first inspection step (S1) is a step of confirming the damage of the guide unit 1 In-guide unit 1 may include a diagnosis step. The diagnosis step of the guide unit 1 is a step of detecting damage that has occurred in the guide unit 1 of the agricultural machine A, and the step can be visually identified and may additionally include an image capture or an X-ray test. .

When the damage of the guide part 1 is confirmed in the diagnosis step of the guide part 1, the repair step S2 is performed by replacing part or all of the guide part 1 according to the damaged part. In particular, since the guide unit 1 is a part where no operational abnormality occurs, the process of checking and repairing the operation abnormality is omitted.

Next, the inspection step (S1) may further include a step of diagnosing the cut part 2, which is a step of diagnosing a failure of the cut part 2. The step of diagnosing the cutting part 2 is a step of detecting a damage or an abnormal operation occurring in the cutting part 2 of the agricultural machine A. This step may be performed through the naked eye, an image photographing, or an X-ray examination, and the operation abnormality is It can be detected by commissioning.

If damage or abnormal operation of the cut part 2 is confirmed in the diagnosis step of the cut part 2, the repair step S2 is performed by replacing part or all of the cut part 2 according to the faulty part. Particularly, the cutting part 2 may be selectively performed in a process of replacing the blade or replacing/improving the driving part of the blade according to the breakage of the blade or abnormal rotation of the blade.

In the above, the improvement process refers to repair of a part in which an operation is performed without replacement of parts, and may include a process of removing foreign substances causing jamming, supplying lubricants, and normalizing a bonding state.

Next, the inspection step S1 may further include a diagnosis step of the transfer unit 3, which is a step of diagnosing a failure of the transfer unit 3 described above. The step of diagnosing the transport unit 3 is a step of diagnosing damage, abnormal operation, or jams occurring in the transport unit 3 of the agricultural machine A, and the corresponding step can also be performed through visual inspection, imaging, or X-ray inspection, and the operation Abnormalities can be detected through trial run.

If damage or abnormal operation of the transfer unit 3 is confirmed in the diagnosis step of the transfer unit 3, the repair step (S2) is performed through all replacement of the transfer unit 3, and when a jamming of the transfer unit 3 is confirmed, the corresponding part The improvement process for is carried out. In particular, even if a failure occurs in a local area, the transfer unit 3 is preferably replaced entirely because of the linkage of the operation, and can be normalized through improvement work only when a jam occurs.

Next, the inspection step (S1) may further include a step of diagnosing the thresher 4, which is a step of diagnosing a failure of the threshing part 4. The step of diagnosing the threshing part 4 is a step of diagnosing damage or abnormal operation occurring in the threshing part 4 of the agricultural machine A, and the corresponding step can also be performed through the naked eye, imaging, or an X-ray examination. Abnormalities can be detected through trial run.

In the diagnosing step of the threshing part 4, if damage or abnormal operation of the threshing part 4 is confirmed, the repair step S2 is performed by completely replacing the threshing part 4. Particularly, since the threshing part 4 is not a structure in which jamming may occur, diagnosis and improvement of jamming are not performed, and it is preferable that the entire threshing part 4 is replaced due to the characteristic of the cylindrical threshing part 4.

Next, the inspection step (S1) may further include a step of diagnosing the chain unit 5, which is a step of diagnosing a failure of the chain unit 5 described above. The chain part 5 diagnosis step is a step of diagnosing damage, operation abnormality, or jam occurring in the chain part 5 of the agricultural machine A, and the corresponding step may also be performed through the naked eye, imaging, or an X-ray examination. , Operation abnormality can be detected through trial operation.

In the diagnosis step of the chain part 5, if damage or abnormal operation of the chain part 5 is confirmed, the repair step S2 is performed through all replacement of the chain part 5, and a jamming of the chain part 5 is confirmed. If so, the improvement process is carried out for the area. In particular, the chain part 5, like the transfer part 3 described above, is preferably replaced entirely because of the linkage of the operation even if a failure occurs in a local area, and can be normalized through improvement work only when a jam occurs.

In addition, in particular, the repair step (S2) for the chain portion 5 is the core of forming a caterpillar, that is, performing the replacement of the chain constituting the chain portion (5).

On the other hand, the agricultural machine (A) further includes a lubricant supply means including a lubricant oil storage tank (not shown) in which the lubricant is stored and a supply nozzle (not shown) for supplying the lubricant, the method according to the inspection step (S1 ) Further comprising the step of detecting the leakage of the lubricant storage tank or the supply nozzle, and the repair step (S2) includes performing replacement of the lubricant storage tank or the supply nozzle.

In the above, the lubricating oil storage tank has a possibility that the problem of leakage of lubricating oil due to damage and cracking due to impact may occur continuously, which leads to a problem leading to a serious defect of the mechanical device, and therefore, it is particularly necessary to be further protected.

To this end, the method may be configured to further include a step of providing a coating film on the outer surface of the lubricating oil storage tank in which the repair step (S2) has been replaced.

Specifically, the coating film is provided on the adhesive layer that is in contact with the outer surface of the lubricating oil storage tank but softens at a first temperature range, and an intermediate layer that is provided on the adhesive layer but is softened at a second temperature range higher than the first temperature, and on the intermediate layer. However, it may include a protective layer softened in a third temperature range higher than the second temperature, and a heating layer provided between the adhesive layer and the intermediate layer to generate heat at a minimum value of the second temperature range.

This coating film suppresses the damage of the storage tank, the occurrence of scratches, and corrosion due to invasion through the protective layer.In particular, by removing the residual stress of the adhesive layer, it suppresses problems such as lifting and cracking due to external environment such as thermal expansion and bending. Furthermore, it solves the problem that the intermediate layer peels due to the difference in stress between the adhesive layer and the protective layer.

In a specific embodiment, first, the adhesive layer may include polybutylacrylate (PBA) and polymethyl methacrylate (PMMA). In order to minimize the difference in softening according to the temperature gradient, the thickness of the adhesive layer is preferably 0.020mm to 0.150mm.

Exemplarily, the adhesive layer may be obtained by heat-coating polybutyl acrylate and polymethyl methacrylate. The range of the first temperature, which is the softening temperature of the adhesive layer, is 90 to 100°C.

Next, the intermediate layer may include 200 parts by weight of a carboxylate acrylic copolymer based on 100 parts by weight of cellulose acetate butyrate. If the weight ratio is out of the above, the adhesive strength between the adhesive layer and the protective layer becomes insufficient, which may cause film peeling. The second temperature range, which is the softening temperature of the intermediate layer, is 150 to 160°C.

Next, the protective layer may include 100 parts by weight of a silicon-containing fiber, 100 parts by weight of silicon carbide, 3 parts by weight of manganese oxide, and 9 parts by weight of an organosilicon-titanium compound, based on 100 parts by weight of polymethylphenylsiloxane.

In the protective layer, if too little polymethylphenylsiloxane is included, the softening temperature decreases and there is a concern that the softening may be softened by heat generation of the heating layer. Compositions of the following protective layer are based on 100 parts by weight of polymethylphenylsiloxane.

The silicone-containing fiber is added to impart water repellency, and the content is preferably 100 parts by weight. If it is less than 100 parts by weight, the water repellency is inferior, and even if it is used in excess of 100 parts by weight, the effect of improving the water repellency is insignificant.

Silicon carbide is added to improve abrasion resistance, and the content is preferably 100 parts by weight. If it is less than 100 parts by weight, abrasion resistance decreases, and even if it is used in excess of 100 parts by weight, the effect of improving abrasion resistance is not large.

The organosilicon-titanium compound is added to improve hardness and abrasion resistance, and the content is preferably 9 parts by weight, and the surface hardness improvement is most pronounced at 9 parts by weight, and even if it exceeds this, the effect of improving hardness is insignificant.

The third temperature range, which is the softening temperature of the protective layer, is 650°C or higher, and is not softened by heat generation of the heating layer, thereby providing strong surface protection performance. Additionally, the protective layer may further include functional additives such as a water repellent agent and an anticorrosive agent.

Next, any heating layer may be used as long as it generates heat by application of electricity, and it suffices to generate heat at the minimum value of the second temperature, which is the softening temperature range of the intermediate layer. In a preferred embodiment, the heating temperature of the heating layer is 150° C., the minimum value of the second temperature in the above example, and this heating layer may include polyacetylene and iodine, and polyacetylene is a conjugated double bond in which electrons flow. Although there is no gap, since the gap can be widened by mixing different kinds of small molecules such as iodine, electrons flow, and when electricity is applied, heat is generated by electrical resistance.

In the above-described coating film, residual stresses such as compressive stress and tensile stress may occur due to factors such as the difference between the object to be protected and the coefficient of thermal expansion, the shape of the object to be protected, and bending due to external force. This is excellent, especially when the heating layer generates heat, the adhesive layer is completely softened, the intermediate layer is partially softened, and the protective layer does not soften, so the residual stress of the adhesive layer is completely removed and the intermediate layer has a small degree of softening. It will play a bridge role. That is, the residual stress of the coating film can be effectively dispersed and relaxed while maintaining the physical and chemical properties of the protective layer.

The present invention described above with reference to the accompanying drawings can be variously modified and changed by a person skilled in the art, and such modifications and variations should be interpreted as being included in the scope of the present invention.
