AI Technical Summary
Existing soil wet-dry cycle experimental equipment is prone to blockage during water circulation due to impurities entering the water pump and water pipes, which affects the equipment life and experimental results.
A filter screen is installed at the water outlet and fixed in place by a spring and a locking block to prevent impurities from entering the water pipe, while also providing a convenient way to replace the filter screen.
It effectively prevents impurities from entering the water pump, extends equipment life, ensures normal equipment operation, and improves the reliability of experimental results.
