Automatic drainage device for farmland

Abstract

The invention discloses an automatic drainage device for farmland. The automatic drainage device comprises a drainage box, wherein a water baffle is fixedly installed on one side of the drainage box, a cover plate is detachably arranged on the upper surface of the drainage box, an automatic drainage mechanism is fixedly arranged on the surface of the drainage box, and a mincing mechanism is fixedly arranged in the drainage box. Compared with the prior art, water in the farmland drives a floating plate to ascend, the floating plate drives a sliding block to vertically ascend, the sliding block drives a sealing door plate and a sealing strip to ascend, water in a paddy field enters the drainage box through a water inlet, a filtering plate filters water in the drainage box, and water in the drainage box is drained out of the farmland through filtering holes; and when the water level in the farmland is reduced, the floating plate synchronously descends along with the water level in the farmland, and meanwhile the sealing door plate synchronously descends along with the water level in the farmland, so that automatic drainage of excessive water in the farmland is completed, the drainage convenience of the farmland is effectively improved, and a large amount of manual operation time is saved.

Description

technical field [0001] The invention relates to the technical field of farmland automatic drainage, in particular to a farmland automatic drainage device. Background technique [0002] Farmland drainage: refers to the artificial measures to remove excess surface water, soil water and groundwater in the farmland, improve the relationship between water, fertilizer, air and heat in the soil, and facilitate the growth of crops. The farmland automatic drainage device in the prior art has the following problems: [0003] 1. Most of the automatic drainage devices for farmland in the prior art realize the automatic drainage of the farmland by manually controlling the valve of the automatic drainage device, which makes the automatic drainage of the farmland extremely inconvenient and wastes a lot of manual operation time; [0004] 2. Since there are many weeds inside the farmland in spring, when the weeds enter the interior of the automatic drainage device, because the automatic dra...

Problems solved by technology

[0003] 1. Most of the automatic drainage devices for farmland in the prior art realize the automatic drainage of the farmland by manually controlling the valve of the automatic drainage device, which makes the automatic drainage of the farmland extremely inconvenient and wastes a lot of manual operation time;

[0004] 2. Since there are many weeds inside the farmland in spring, when the weeds enter the interior of the automatic drainage device, because the automatic drainage device for farmland in the prior art lacks the function of crushing weeds, it is extremely easy to cause damage to the interior of the automatic drainage device. blockage;

[0005] 3. When there are many impurities and sludge in the water inside the farmland, due to the lack of decontamination function of the farmland automatic drainage device in the prior art, the impurities and sludge on the surface of the filter plate cannot be removed in time, resulting in insufficient drainage of the automatic drainage device. Unobstructed, for this reason, we propose a farmland automatic drainage device to solve the above problems
