[0002] The land after mine restoration may be severely damaged, with poor soil, lack of nutrients, and potential acidification or salinization. Using reservoirs to store collected rainwater as a water source, combined with irrigation systems, can provide moisture during the restoration process, promoting plant root growth and establishment.

[0003] A watering device for repairing abandoned mines disclosed in Chinese patent disclosure specification CN219182311U, through the arrangement of limit blocks, springs, sliding shafts, etc., when impurities accumulate too much in the filter or it is damaged and needs to be replaced, the fixing rod is pushed to make the limit block move away from the limit groove, and then the fixing rod is rotated to make the limit block rotate in the arc groove, and finally the fixing rod is pulled to make the limit block move away from the vertical groove, so that the filter can be replaced, which facilitates the cleaning or replacement of the filter.

[0004] Although the above-mentioned irrigation device for abandoned mine restoration can lift the entire filter barrel by pulling the pull ring to clean the impurities and sludge attached to the inside, it is found in actual application that the filter screen set at the inlet of the main outlet pipe is not convenient for cleaning. Over time, the filter screen set at the inlet of the outlet pipe connected to the water pump will be blocked, resulting in reduced water permeability, which is not conducive to irrigation operations. For this reason, we provide a rainwater irrigation device for mine ecological restoration. Utility Model Content
