A support plate is fixedly connected inside the machine case, and a mounting seat is fixedly connected to the top of the support plate. A container is installed on the top of the mounting seat. Multiple spherical plain bearings are placed inside the container. A wire mesh cover is arranged on the side of the container. There are four wire mesh covers, and the four wire mesh covers are distributed on the four sides of the container. An electric push rod is arranged on the top of the machine case.

Multiple spherical plain bearings are sequentially placed inside the container. The first water pump is turned on. The first water pump acts on the first built-in pipe to extract the cleaning liquid inside the water tank. The cleaning liquid sequentially passes through the first built-in pipe, the first water pump, the second hose, the first hose, the first transmission pipe and the second transmission pipe. Finally, the cleaning liquid is sprayed out from the multiple spray heads on the left and right sides of the container. The cleaning liquid passes through the wire mesh cover until it cleans the multiple spherical plain bearings. The electric push rod operates, continuously expands and contracts. The electric push rod drives the first transmission pipe, the second transmission pipe and the spray heads to repeatedly move up and down, further improving the cleaning effect, simply operating to quickly place spherical plain bearings, increasing the number of spherical plain bearings to be cleaned, saving time and improving the operation efficiency.

A second built-in pipe is fixedly connected to the bottom of the second water pump. The second built-in pipe is inside the storage tank. The cleaning liquid converges in the storage tank after passing through the leakage holes and the diversion groove. The second water pump operates and extracts the cleaning liquid in the storage tank through the second built-in pipe. The cleaning liquid successively passes through the second built-in pipe, the second water pump and the third hose and converges back into the water tank again. The cleaning liquid is recycled, saving resources and improving environmental protection.

[0011] For further improvement, a first filter plate is arranged inside the diversion groove. A second filter plate is arranged below the first filter plate. The leakage holes, the first filter plate and the second filter plate work together to effectively filter solid impurities in the cleaning liquid and improve the cleanliness of the cleaning liquid during the recycling process.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By sequentially placing a plurality of spherical plain bearings inside the container, starting the first water pump, the first water pump acts on the first built-in pipe to extract the cleaning liquid inside the water tank.
