Abstract

The invention relates to a paddy field water-level drainage and irrigation control device. The paddy field water-level drainage and irrigation control device comprises a gate sleeve, wherein a slide slot is formed in the gate sleeve; a gate plate is arranged in the slide slot; the two sides of the gate sleeve are separately provided with water tubes; a lifting rod is arranged on the gate plate; a threaded section is arranged on the lifting rod; the threaded section is in screw-thread fit with a hand wheel with a screw hole in middle; the hand wheel is used for controlling the gate plate to lift and drop; and the upper end or the lower end of the hand wheel is further provided with a locking nut which is in screw-thread fit with the threaded section of the lifting rod. The paddy field water-level drainage and irrigation control device is relatively simple in structure, is convenient to operate, can be directly embedded into a ridge, can be used on a soil ridge and a cement ridge, is relatively small in size, does not damage the soil ridge, and further can solve the soil erosion problem in a water irrigation and drainage process.

Description

technical field [0001] The invention relates to the technical field of paddy field water level control, in particular to a paddy field water level drainage and irrigation control device. Background technique [0002] In the existing rice production, there are mainly two ways to design the drainage and irrigation outlets of paddy fields: (1) directly excavate the field ridge soil for water irrigation and drainage, and then wrap the irrigation and drainage outlets with soil or film after completion closed. (2) Use wooden boards as partitions to seal the irrigation inlet. This method is generally used on cement ridges in production, mainly in research units and demonstration bases, and is not widely used by ordinary farmers. [0003] These methods have the following two problems: (1) directly excavating the field ridge for irrigation and drainage is not conducive to controlling the amount of irrigation and drainage. During the process of irrigation and drainage, the water volu...
