Problems solved by technology

Traditional dryland farmland drainage ditches are in a state of natural drainage, without any controlled drainage, causing surface water with high concentrations of nitrogen and phosphorus to flow out of the farmland at the beginning of rainfall, polluting the surrounding water bodies
The control gate for surface drainage of farmland is installed in the drainage ditch, which is manually operated or controlled by a computer. There is no automatic opening gate directly installed in the farmland.

Abstract

An automatically openable gate for controlling the draining of agricultural field structurally features that the rotary bearing for the joining spring on the top of the gate and the rotary bearing for the turn buckle on the top of right frame of the gate are respectively installed to the tops of the gate and the right frame, and the tensional spring and turn buckle are arranged between said two bearings. Its advantages are simple structure and low cost.

Description

technical field [0001] The invention relates to a farmland control drainage automatic opening gate for controlling the farmland drainage gate, and belongs to the technical field of agricultural water and soil engineering. Background technique [0002] In the United States and Europe, farmland drainage is carried out through underground drainage pipe network systems, and the opening of drainage gates is controlled by computers. my country is installed in the gutter for the control gate of farmland surface drainage, with manpower operation or with computer control, the automatic opening gate that is directly installed in the farmland does not have yet. Globally, agricultural non-point source pollution is one of the main sources of water pollution. In dry farmland with less crop vegetation and no surface water, the surface runoff of inorganic and organic nitrogen and phosphorus adsorbed and bound on the surface of sediment particles with rainfall (especially heavy rain) is the...
