A layered terrace water level anti-silt blockage drainage control device

Abstract

The invention discloses a layered terrace water level sediment blockage preventing drainage control device. The device comprises a water level release line plate and a water level control way; the bottom end of the water level release line plate is connected with the top end of a main mounting body; the water level release line plate comprises a main control rod, an extension assistance rod, an arc slide angle, a water level main adjusting block and a mounting fork; when equipment is mounted in a drainage port of a terrace through the mounting fork, the needed water level is adjusted through external force along with the water level control way by an outer hole auxiliary rod; when sandstones butt against a pressure convex block, a main clamping block pushes out crushed angles, a weight body changes the gravity center to move down, a return assisting ball can slide along with a rolling way, and is assisted to roll by a smooth rim; the external sandstones are crushed by the crushed angles, and fragments flow out or are precipitated; and when a water outlet is blocked by the sandstones, the sandstones can be timely crushed through self gravity, so that the preferable drainage is achieved, and the condition of bad drainage caused by blockage is prevented.

Description

technical field [0001] The invention belongs to the field of agriculture, and more specifically relates to a water level anti-sediment blockage drainage control device for layered terraced fields. Background technique [0002] The agricultural products planted in the terraced fields have relatively high water level requirements, and the amount of water required for different agricultural products is also different. Each step has a drainage outlet, and a water level control device will be installed. The terraced fields are formed by accumulation of soil. The sand will be washed away. [0003] Based on the above-mentioned inventor's discovery, the existing farmland water level control device mainly has the following deficiencies, such as: [0004] When the terraces are washed in rainy days, and the water level is too high and the water level needs to be adjusted, the sand and stones washed down will flow out together, which is easier to block the drainage outlet, causing the ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technology for scouring the terraces in rainy days, and the water level is too high and the water level needs to be adjusted, the washed sand and stones will flow out together, which is easier to block the drainage outlet and make the water level increase rapidly. Problems that lead to a decline in the yield of agricultural products
