In the drawing, reference numeral 26 denotes a shroud that guides the air passing through the cooling module 11 smoothly to the engine side according to the cooling fan driving, and 30 is a bracket on which the driving motor 16 is mounted.

On the other hand, the description of the configuration of the cooling module and the insect net including the radiator, the charge air cooler, the oil cooler described above is substantially the same as the configuration in the technical field to which the present invention belongs, the detailed description of their configuration and operation Omit.

Hereinafter, with reference to the accompanying drawings an example of the use of the air cleaning system of a construction machine according to an embodiment of the present invention will be described in detail.

A) In the air cleaning system of a construction machine according to an embodiment of the present invention, the operation of the air cleaning system according to the on / off switch operation of the driver will be described (semi auto type).

As shown in FIG. 4, in order to clean foreign substances such as dust and fallen leaves accumulated on the core and the insect repellent net 12 of the cooling module 11 including the writer, the charge air cooler and the oil cooler described above, the driver's cab The on / off switch 22 installed in the cap (not shown) is operated in an ON state (see S100).

The above-mentioned ON operation signal of the on / off switch 22 is input to the control unit (V-ECU) 24, and the air pump 10, the cylinder 15, and the driving motor 16 are received from the control unit 24. By applying an electrical signal to the), the air cleaning system for removing the foreign matter accumulated on the core and the insect net 12 of the cooling module 11 is operated (see S200). At this time, the control unit (V-ECU) transmits a status (status) that the foreign matter removal operation is in progress to the instrument panel (I-ECU), and displays it (cleaning for cooling module and net is on-going).

1 and 2, due to the vertical movement of the cylinder 15 installed in the cooling module 11, the air tube 14 mounted on the cylinder rod between the cooling module 11 and the insect repellent net 12 It is elevated. At the same time, the air tube 14 rotatably supported by the cylinder rod during the vertical movement of the cylinder 15 is rotated by the drive motor 16.

As shown in FIG. 3, the engine is driven at high temperature and high pressure through a turbo charger 23 through which a clean air filtered by the air cleaner 17 is filtered for combustion air. Inhalation. That is, some of the combustion air supplied to the engine combustion chamber through the air supply pipe 18 is supplied to the air pump 10 through the branch pipe 19 branched to the air supply pipe 18.

Therefore, the air pressure discharged from the air pump 10 passes through the conduit 21 and is supplied to the air tube 14, and the cooling module 11 is caused by the air pressure discharged through the nozzle 13 formed in the air tube 14. The foreign matter such as dust accumulated on the core and the insect repellent net 12 can be cleaned. The air pump 10 described above is driven in a low idle state and is in a standby state before being operated in an ON state of the on and off switches 22. At this time, when the air pump 10 is switched to the on state of the on, off switch 22, the rotation speed is increased to suck a large amount of air flow (air flow) to supply to the air tube (14) side.

When the on / off switch 22 is operated in the OFF state by the driver while removing foreign matters such as dust accumulated on the core of the cooling module 11 and the insect repellent net 12 (see S300). ), The electric signal is output from the control unit to the air pump 10, the cylinder 15, and the driving motor 16 so as to stop these driving, and thus, dust accumulated on the core and the insect repellent net 12 of the cooling module 11. The cleaning operation to remove foreign matters is stopped (see S400).

On the other hand, by operating the on, off switch 22 to the on (ON) state by the driver (see S100) after the cleaning to start to remove the foreign matter on the core and the insect net 12 of the cooling module 11 (S200) 10 minutes after the OFF signal of the ON / OFF switch 22 is not applied, the air pump 10, the cylinder 15, and the driving motor 16 are stopped from the control unit. Since the control signal is output, the foreign matter removal operation on the core and the insect repellent net 12 of the cooling module 11 is completed (see S500).

B) In the air cleaning system of a construction machine according to an embodiment of the present invention, it describes the operation of the air cleaning system according to the set operating time of the equipment (automatic type).

As shown in FIG. 4, the air cleaning system is operated when the set operating time of the equipment (excavator) elapses regardless of the operation button operation by the driver.

That is, when the engine of the equipment is running for a set time (for example, 4 hours), dust accumulated on the core and the insect net 12 of the cooling module 11 consisting of a writer, a charge air cooler, an oil cooler, The work of cleaning foreign matter such as fallen leaves is started (see S100).

As the electric signal is applied to the air pump 10, the cylinder 15, and the driving motor 16 from the control unit 24 described above, foreign matter accumulated on the core and the insect repellent net 12 of the cooling module 11 is removed. The air cleaning system is removed to operate (see S200). At this time, the control unit (V-ECU) transmits a status (status) that the foreign matter removal operation is in progress to the instrument panel (I-ECU), and displays it (cleaning for cooling module and net is on-going). At this time, the operation of removing foreign matter accumulated on the core of the cooling module 11 and the insect repellent net 12 by the air pressure supplied from the air pump 10 and discharged through the nozzle 13 is performed by the driver's on / off switch ( 22) The same operation to remove the foreign matter by the ON operation, the detailed description thereof will be omitted.

As described above, when the stop button 25 is operated by the driver while removing the foreign matter on the core of the cooling module 11 and the insect repellent net 12 (see S300), the air pump 10, the cylinder from the controller Since the electric signal is output to the driving motor 16 and the driving motor 16, the cleaning operation for removing the foreign matter on the core of the cooling module 11 and the insect repellent net 12 is stopped (see S400).

Meanwhile, the engine of the equipment is operated for a calculation of operating hour (for example, 4 hours) to remove foreign substances on the core of the cooling module 11 and the insect repellent net 12, and then the stop button 25 on the control unit. If the control signal of the) is not applied, the control signal is output from the control unit 24 to the air pump 10, the cylinder 15, and the drive motor 16 within 5 minutes, so that the cooling module 11 is stopped. The foreign material removal work on the core and the insect repellent net 12 is completed (see S500).

According to the air cleaning system of a construction machine according to an embodiment of the present invention as described above, the work required for maintenance as the driver cleans and cleans the foreign substances accumulated on the core and the insect net of the cooling module such as a radiator It can save time. The maintenance of equipment is performed periodically or systematically, which ensures the best equipment performance and prevents degradation of performance and quality of related parts.
