Solar micro-power self-cleaning irrigation ditch trash rack

The invention relates to a self-cleaning irrigation ditch trash rack which comprises fixed grids and movable grids, the fixed grids and the movable grids are arranged in an alternate mode and provided with saw teeth with tip ends facing upwards respectively. The fixed grids are arranged on a grid support. The grid support is inclined. The upper ends of the movable grids are arranged on an eccentric rod. The lower middle portions of the movable grids are arranged on a first bearing shaft. The eccentric rod is arranged on the eccentric position of an eccentric wheel in a rolling mode. The eccentric wheel is connected with a motor in a transmission mode. The two ends of the first bearing shaft are arranged in a second sliding groove in a rolling mode. The movable grids are higher than the fixed grids to support sundries when swinging upwards, the movable grids are lower than the fixed grids to enable the sundries to be left on the fixed grids when swinging downwards, and the sundries are pushed to the top through the reciprocating motion. The upstream portion of the grid support is provided with a front electronic water level gauge, the downstream portion of the grid support is provided with a rear electronic water level gauge, and intervals are reversed between the front electronic water level gauge and the bottom of a ditch and between the rear electronic water level gauge and the bottom of the ditch. The front electronic water level gauge and the rear electronic water level gauge are arranged vertically and equal in bottom height, and the motor is triggered to work when the water level difference reaches the set value. The self-cleaning irrigation ditch trash rack has the advantages that the sundries blocked on the door of the crossing openings of the field ditch can be cleaned automatically, and the agricultural irrigation efficiency is improved.
