The invention relates to the field of agriculture, in particular to multi-mode farmland drainage equipment which comprises a drainage body, a water inlet pipe, a water outlet pipe, a water storage valve, a motor assembly and a sealing cover. The device can discharge accumulated water in a farmland, and has four selectable use modes of electric auxiliary discharge, manual auxiliary discharge, electric direct discharge and manual direct discharge; according to the device, an optional nitrogen and phosphorus filtering assembly is further arranged for nitrogen and phosphorus in accumulated water, a user can select a nitrogen and phosphorus filtering mode or a direct connection mode, and when the flow is too small and the power of the motor is very large in the nitrogen and phosphorus filtering mode, the device can be automatically switched to the direct connection mode to prevent overload of the motor; the device also performs impurity filtration on accumulated water entering the water inlet pipe, so that the pipeline is prevented from being blocked by objects such as wheat straws, and an impurity filtration part on the water inlet pipe is not in direct contact with the ground, so that the possibility that the water inlet pipe is blocked or polluted by sludge is reduced.
本发明涉及农业领域，具体地说是一种多模式农田排水设备，包括排水主体、进水管、出水管、蓄水阀、电机组件和密封盖。本装置能够对农田中的积水实施排放，且具有电动辅助排放、手动辅助排放、电动直接排放和手动直接排放四种可供选择的使用模式；本装置还针对积水中的氮和磷设置了可供选择的氮磷过滤组件，用户可以选择氮磷过滤模式或者直通模式，且当氮磷过滤模式下流量过小而电机功率很大的时候，本装置会自动切换至直通模式来防止电机过载；本装置还对进入进水管的积水进行了杂物过滤，防止了麦秸等物体堵塞管道，且进水管上的杂物过滤部件不与地面直接接触，进而减小了进水管被淤泥堵塞或污染的可能性。
