The overwhelmingly many! /, Part of the cleaning liquid is supplied as fuel for the fuel cell. The cleaning liquid and fuel are not limited to ethanol, and methanol and other alcohols can be used. However, ethanol's direction S methano It is preferable to use ethanol because it is less toxic than ethanol and is easily available.

[0014] The sieve system 1 includes a sieve 2 and a blade tip cleaning device 3. When the sieve 2 is mounted on a cleaning dish 25 that is a predetermined mounting position of the blade tip cleaning device 3, the sieve 2 Alcohol is supplied as a cleaning liquid to the blade edge portion 6, and the blade edge portion 6 is cleaned and further dried. At the same time, alcohol is supplied as fuel to the fuel tank 13 of the first fuel cell 8 on the side of the sieve built in the sieve 2 as necessary.

[0015] As shown in FIGS. 2A and 2B, the sieve 2 includes a blade edge portion 6 composed of an inner blade and an outer blade, a motor 5 that is a driving means for the inner blade, alcohol fuel, and oxygen in the air. A first fuel cell 8 that generates electricity by reaction, a secondary battery 7 that stores a certain amount of power generated by the first fuel cell 8, and a removable cartridge fuel tank that stores alcohol fuel 13, pump 16 that sucks alcohol fuel from the fuel tank 13 and supplies it to the first fuel cell 8, a remaining amount sensor 18 that constantly measures the remaining amount of alcohol fuel in the fuel tank 13, and operation of the shaft 2 The circuit unit 15 is provided.

[0016] In the sieve 2, when a switch (not shown) is operated, the circuit portion 15 formed on the substrate 15

1S The power generated in the first fuel cell 8 and the power accumulated in the secondary battery 7 are applied to the motor 5, and the inner blade is reciprocated linearly, thereby removing the hair between the inner blade and the outer blade. Done. As the power source of the motor 5, mainly the electric power generated in the first fuel cell 8 on the side of the sieve is used, and the electric power charged in the secondary battery 7 at the start of the motor 5 is used as an auxiliary. A capacitor may be used instead of the secondary battery 7.

[0017] The fuel tank 13 is configured to be detachable from the body of the seeker 2 as described above. When the fuel tank 13 is mounted on the sieve 2, the pump 16 is driven and supplied to the first fuel cell 8 via the fuel tank 13, the alcohol fuel force S drawn up, and the pipe line 17. Further, in the fuel tank 13, when the sieve 2 is mounted on the cleaning dish 25 of the blade cleaning device 3, it is connected to the pipe 45 of the blade cleaning device 3 and opened, and the sieve 2 is opened in the cleaning dish of the blade cleaning device 3. A valve element 19 is provided that closes when removed from 25. Therefore, alcohol fuel does not leak from the fuel tank 13 even if the sieve 2 is removed from the cleaning dish 25 of the blade edge cleaning device 3. [0018] The first fuel cell 8 has a configuration in which the electrolyte membrane 12 is sandwiched between the force sword 10 and the anode 11, and the alcohol and the oxygen in the air are used as the energy source by the al fuel sucked up by the pump 16. To generate electricity. During power generation, air (oxygen) is taken in and water is discharged on the power sword 10 side. The water is once absorbed by an absorbent material (not shown) such as cloth and then released into the air. On the anode 11 side, alcohol fuel such as ethanol is taken in and carbon dioxide is discharged. As shown in FIG. 2A, the generated electric power is input to the circuit unit 15 formed on the substrate, boosted, and stored in the secondary battery 7.

On the other hand, as shown in FIG. 1, a cartridge type cleaning liquid tank 27 in which an alcohol cleaning liquid 20 is stored is detachably attached to the bottom of the blade edge cleaning device 3. The blade edge cleaning device 3 is a second fuel on the blade edge cleaning device side that generates electricity by reacting alcohol fuel and oxygen in the air with a cleaning pump 30 that supplies the alcohol cleaning liquid 20 in the cleaning liquid tank 27 to the cleaning dish 25. The battery 36, the scavenger pump 31 and the pipe 45 (sheber fuel supply mechanism) for supplying the alcohol cleaning liquid 20 in the cleaning liquid tank 27 as fuel to the fuel tank 13 of the sieve 2 and the alcohol cleaning liquid 20 in the cleaning liquid tank 27 A battery pump 32 and a pipe 47 (fuel supply mechanism for the blade edge cleaning device) for supplying the fuel to the second fuel cell 36 as fuel and a control circuit (control unit) 35 for controlling the operation of the blade edge cleaning device 3 ! /

[0020] The blade tip cleaning device 3 drives the cleaning pump 30 to suck up the alcohol cleaning solution 20 stored in the cleaning solution tank 27, and passes through the conduit 41 and the filter 49 for removing swarf 25 to the cleaning dish 25. Feed on. Therefore, the blade edge cleaning device 3 can be cleaned by immersing the blade edge portion 6 of the shear 2 in the alcohol cleaning liquid 20 when the sieve 2 is mounted at a predetermined mounting position. Note that the cutting edge portion 6 of the shiver 2 can also be cleaned while appropriately vibrating the cutting edge portion 6 of the shiver 2. When the cleaning of the blade edge portion 6 is completed, the solenoid valve 43 is opened, and the alcohol cleaning liquid 20 in the cleaning dish 25 is discharged to the cleaning liquid tank 27 through the conduit 42. And, at the bottom of the cleaning liquid tank 27, sawdust is deposited. After cleaning, the air blower 50 is driven to dry the blade edge 6 of the shiver 2.

The second fuel cell 36 on the blade edge cleaning device side has a configuration in which the electrolytic membrane 40 is sandwiched between the cathode 37 and the anode 38, similarly to the first fuel cell 8 of the shiver 2. This second burn The battery 36 is stored in the cleaning liquid tank 27 and uses alcohol such as ethanol as an energy source. In the blade edge cleaning device 3, by driving the battery pump 32, the alcohol cleaning liquid 20 is sucked from the cleaning liquid tank 27 through the conduit 47 and the filter 48 for removing swarf and supplied to the second fuel cell 36 as alcohol fuel. Then, power is generated by reacting alcohol with oxygen in the air.

[0022] During power generation, air (oxygen) is taken in and water is discharged on the side of the force sword 37. The water is once absorbed by an absorbent material (not shown) such as a cloth and then diffused into the air. On the anode 38 side, alcohol is taken in and carbon dioxide is discharged. The generated electric power is supplied to a cleaning pump 30, a sieve pump 31, a battery pump 32, a solenoid valve 43, a blower 50, a control circuit 35 that drives and controls them. Note that the power generated by the second fuel cell 36 may be supplied to the secondary battery 7 of the sieve 2.

In the shearer system 1, the shearer 2 is mounted at a predetermined mounting position of the blade edge cleaning device 3, and a cleaning instruction signal is transmitted from a predetermined operation switch (not shown) provided in the blade edge cleaning device 3. Is input to the control circuit 35, the control circuit 35 inquires of the remaining amount sensor 18 of the sieve 2 about the remaining amount of alcohol fuel in the fuel tank 13. The control circuit 35 drives the sieve pump 31 of the blade edge cleaning device 3 when the remaining amount of alcohol fuel in the fuel tank 13 is equal to or less than a predetermined amount. As a result, the alcohol cleaning liquid 20 stored in the cleaning liquid tank 27 is sucked up by the siever pump 31 through the pipe 45 and the filter 46 for removing swarf, and is supplied to the fuel tank 13 of the sieve 2 as alcoholic fuel. Supplied.

[0024] As described above, in the seeker system 1 according to the present embodiment, when the seeker 2 is attached to the blade edge cleaning device 3, the blade edge cleaning device 3 itself determines the necessity of replenishing alcohol fuel to the sieve 2; Alcohol fuel is automatically supplied to the fuel tank 13 of the sieve 2 when replenishment is required. Therefore, the user need not pay much attention to the remaining amount of alcohol fuel in the first fuel cell 8 of the shiver 2 and can use the shieno at any time. In addition, the user is freed from the trouble of supplying alcohol fuel to the sieve 2. Further, the amount of alcohol cleaning liquid 20 stored in the cleaning liquid tank 27, the amount of alcohol fuel supplied to the fuel tank 13, and the second fuel of the blade edge cleaning device 3 Since the amount of alcohol fuel consumed in the fuel cell 36 is overwhelmingly large, the consumption by the first fuel cell 8 and the second fuel cell 36 can be virtually ignored. As a result, the user only needs to replace the alcohol cleaning liquid 20 stored in the cleaning liquid tank 27 by checking the degree of contamination of the alcohol cleaning liquid 20. In addition, since a part of the alcohol cleaning liquid that is finally disposed of can be used as alcohol fuel, the fuel cost can be reduced and the amount of waste can be reduced.

Alcohol fuel is automatically supplied (supplemented) to the fuel tank while the cutting edge is being cleaned, so the user can pay little or no attention to the remaining amount of alcohol fuel in the Sieva fuel cell. You can use the Siever at any time. In addition, the user is freed from the trouble of supplying alcohol fuel to Sieba himself. The power used in the blade cleaning device may be supplied from commercial power via an AC adapter, which is not necessarily supplied from the fuel cell. In this case, as in the conventional example, the usable range of the blade cleaning device is limited, but alcohol consumption can be reduced.

Furthermore, the blade edge cleaning apparatus according to the present invention includes a fuel cell that uses alcohol fuel as an energy source and supplies power, and a fuel supply mechanism for the blade edge cleaning apparatus that supplies alcohol to the tank power fuel cell.
