Automatic oil filtering device for loader gearbox

Abstract

The invention discloses an automatic oil filtering device for a loader gearbox. An oil suction port is formed in the bottom of the gearbox, and an oil spraying port is formed in the upper middle portion of the gearbox; the left side of the oil suction port is sequentially connected with a first pipe joint, a ball valve, a second pipe joint, a fine filter, a third pipe joint and an oil suction pipe, the other end of the oil suction pipe is connected with an oil inlet of an electric oil suction pump, an oil outlet of the electric oil suction pump is connected with an oil outlet pipe, and the other end of the oil outlet pipe is connected with an oil spraying pipe joint and then is mounted on the oil spraying port, so that oil filtered by the fine filter is sprayed out from the oil spraying port, and then parts in the gearbox are forcibly lubricated; and the electric oil suction pump mounted on the right side of the gearbox is connected with a complete machine power source through a wire.The device is simple in structure, good in oil filtering effect and convenient and efficient to maintain, and the problems that in the prior art, due to large working condition loads, severe working environments and the like, the cleanliness of the oil is poor, and the gearbox oil needs to be frequently replaced are solved.

Description

technical field [0001] The invention relates to a loader gearbox assembly, in particular to a loader gearbox oil automatic filter device. Background technique [0002] The loader gearbox generally adopts a hydraulic gearbox, which converts the mechanical energy of the engine into hydraulic energy and restores the hydraulic energy to mechanical energy. The torque converter with oil as the medium replaces the mechanically connected main clutch. The working oil can absorb and eliminate the impact, vibration and noise caused by the engine itself and external loads, thereby protecting the diesel engine and transmission system and improving the use of the loader. Life; on the other hand, the lubrication of parts inside the gearbox, gear control, etc. are also realized through oil. With the continuous advancement of science and technology, electronically controlled gearboxes are more and more widely used in high-end loaders. Since loaders are mainly used in earthwork machinery for...
