  By the way, in the apparatus of Patent Document 1, each operating unit is operated by a main operation unit according to a set operation program in accordance with a vehicle type, a degree of dirt, and the like. As a result, cleaning is possible in accordance with any degree of vehicle type contamination.

  However, in reality, depending on the type and state of the mud stuck to the endless track, or the sticking site, there is a problem that the mud cannot be completely removed by washing the car with only the set operation program.

  In order to solve such a problem, the present invention is provided with a pair of guide rails arranged along both side surfaces of an endless track type vehicle, a pair of bases moving back and forth along the guide rails, and the bases. A cleaning device composed of a pair of nozzle devices that move up and down and swing, and a pump that supplies cleaning water to the nozzle device, and the cleaning device is operated according to a set program to automatically execute cleaning. The gist of the present invention is to provide an endless track type vehicle cleaning device that includes an operation unit and a portable sub-operation unit that allows the cleaning device to be arbitrarily remotely operated and manually perform cleaning.

  Further, the nozzle device can be a cleaning device that can obtain a higher cleaning effect by comprising a nozzle that injects a large flow of cleaning water at a low pressure and a nozzle that injects a small flow of cleaning water at a high pressure. .

  The apparatus of the present invention operates the nozzle device along an endless track according to the program set in the main operation unit, and after cleaning the endless track by jetting strong cleaning water, the portable sub-operation unit By operating the same nozzle device and dropping the mud that could not be removed by visual inspection, it is possible to perform complete cleaning, and cleaning is performed at the portable sub-operation unit. Since it is possible to perform cleaning at a distance where the operator does not directly receive the rebound of mud and cleaning water that occurs sometimes, it is a safe cleaning operation. Furthermore, when cleaning by the portable sub-operation unit, the operator uses a nozzle device that moves along the vicinity of the endless track, rather than holding a nozzle device that has a large reaction during the injection and maintaining a certain distance. Therefore, the burden on the operator can be reduced as much as possible, and since the distance between the nozzle injection port and the endless track is short, powerful cleaning can be performed without causing much attenuation of the cleaning power.
