Farmland water conservancy circulation irrigation and drainage facility

Abstract

The invention discloses a farmland water conservancy circulation irrigation and drainage facility. The facility structurally comprises a channel, a water inlet pipe and a baffle, the water inlet pipeis installed in the middle of the right end of the channel, the baffle is arranged at the left side in the channel, due to the fact that impurities are clamped outside a filter screen under the thrustof water flow, the drainage speed of the filter screen is decreased, a dredging device is repeatedly and movably matched with the right side of the filter screen under the pushing force of liquid, the impurities in the filter screen are dragged and brought out by teeth, accumulation of the impurities in the filter screen is reduced, the drainage speed of the filter screen is increased, the waterconsumption suitable for planting agriculture is controlled, and planting growth of crop is facilitated; and the impurities in liquid easily enter a liquid accumulation chamber, so that the gravity ofremoving teeth is increased, the liquid is filtered for multiple times through a blocking plate in a water inlet hole, the impurities entering the liquid accumulation chamber are reduced, the volumeof the liquid accumulation chamber can be kept, the bearing capacity of the removing teeth is reduced, the moving speed of the removing teeth is increased, and the impurities in the filter screen areremoved.

Description

technical field [0001] The invention belongs to the field of water conservancy, and more specifically relates to a farmland water conservancy cycle drainage and irrigation facility. Background technique [0002] In the process of planting crops in the farmland, in order to ensure that the crops have appropriate moisture, the farmland is connected to the river through irrigation canals, and the irrigation canals are controlled to ensure the water volume of the farmland. In order to reduce impurities in the rivers from entering the farmland, the irrigation canals are equipped with The filter screen blocks the filtering of impurities; in the prior art, when the irrigation canal is used for irrigation and drainage of farmland, the impurities are stuck outside the filter screen due to the thrust of the water flow, causing the drainage speed of the filter screen to slow down, and a large amount of liquid enters the inside of the channel body, causing the liquid to flow into the can...

[0002] In the process of planting crops in the farmland, in order to ensure that the crops have appropriate moisture, the farmland is connected to the river through irrigation canals, and the irrigation canals are controlled to ensure the water volume of the farmland. In order to reduce impurities in the rivers from entering the farmland, the irrigation canals are equipped with The filter screen blocks the filtering of impurities; in the prior art, when the irrigation canal is used for irrigation and drainage of farmland, the impurities are stuck outside the filter screen due to the thrust of the water flow, causing the drainage speed of the filter screen to slow down, and a large amount of liquid enters the inside of the channel body, causing the liquid to flow into the canal. The top of the irrigation canal overflows into the farmland in other areas, which cannot control the amount of water suitable for planting agriculture and affects the planting and growth of crops
