Summary of the Utility Model

The adsorption cotton is installed on the plug-in frame.

[0007] As a preferred technical solution of the utility model, the plug-in frame is in a "mouth" shape structure, and the plug-in frame covers the oil inlet, so as to facilitate filtering the inhaled lubricating oil.

[0008] As a preferred technical solution of the utility model, a blocking plate for shielding the oil inlet is slidably connected to the installation shell at the plug-in frame. A spring is installed between the blocking plate and the installation shell. The blocking plate is in a "匚" shape structure, so as to prevent the lubricating oil from leaking out when the insertion frame is pulled out.

[0009] As a preferred technical solution of the utility model, the driving assembly includes a main pulley, a main pulley is installed on the output shaft, a slave pulley is installed on the driving shaft, and a transmission belt is installed between the main pulley and the slave pulley, so as to facilitate driving the driving shaft to rotate and achieve the purpose of controlling the operation of the turbine.

[0010] As a preferred technical solution of the utility model, the turbine is provided with three groups, and the oil inlet and the oil outlet are also provided with three groups, so as to increase the adsorption efficiency of impurities.

[0011] As a preferred technical solution of the utility model, the oil inlet is located at the bottom side of the mounting shell, and the oil outlet is located at the top of the mounting shell, so that impurities deposited at the bottom can be sucked and adsorbed.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model installs the power take-off body on the gearbox by arranging a drive shaft, adsorption cotton and a turbine, and injects lubricating oil into the power take-off body. When the gearbox is working, it can drive the power take-off to work, and the output shaft on the power take-off body rotates, thereby driving the drive shaft to move through the main pulley, the transmission belt and the slave pulley. When the drive shaft is working, it drives the turbine to rotate, thereby sucking the lubricating oil at the bottom of the installation shell from the oil inlet and then discharging it through the oil discharge port. At the same time, the adsorption cotton at the oil inlet can intercept impurities in the lubricating oil, thereby extending the service life of the lubricating oil, which is more economical.

[0014] 2. The utility model provides a plug-in frame and a blocking plate, and the adsorbent cotton needs to be replaced regularly. When replacing, the nut on the plug-in frame is unscrewed, and the plug-in frame is pulled out, thereby driving the adsorbent cotton to be taken out and replaced.
