Self-suction well

Abstract

The invention discloses a self-suction well, which belongs to the technical field of agricultural production equipment. The self-suction well comprises a double-layer plastic film (2), a well body (3), a well water sucker (5), a cover (7), capillary cores (10), thin water guide cores (11), thick water guide cores (12), a capillary bundle (13), an irrigation cover cavity (16), a bearing water-storing plate (17) and water storage troughs (19). The well water sucker (5) is disposed at the lower end of the well body (3) and inside a water course (4). The double-layer plastic film (2) is disposed at the upper end of the well body (3). The bearing water-storing plate (17) is disposed on the well body (3). The self-suction well is an agricultural production facility designed according to the principle of capillary and is powered by pull generated under the action of surface water evaporation and plant transpiration to suck water up from a surface runoff layer to roots of crops, thereby automatically supplementing water required by growth of the crops. Great waste caused by existing irrigation ways can be avoided, farmland water utilization rate can be increased, and production cost can be reduced for farmers.

Description

technical field [0001] The invention relates to a self-priming well, which belongs to the technical field of agricultural production equipment. Background technique [0002] Groundwater is water that exists in cracks in crustal rocks or in soil voids. According to different buried conditions, groundwater can be divided into three categories: perched water, phreatic water and artesian water. Perched water in the upper layer is a water storage body formed by infiltrating atmospheric precipitation staying in shallow rock cracks or sedimentary layers due to local water isolation. Diving is the groundwater buried on the first stable aquifer below the surface, and most of the groundwater you see is diving. Springs form when submerged water flows out of the surface. Artesian water is groundwater buried deep and flowing between two aquifers. This kind of groundwater often has relatively large water pressure, especially when the upper and lower aquifers are inclined, the water ...

Problems solved by technology

[0006] In order to overcome the huge waste caused by the current irrigation method, improve the water utilization rate of farmland, and reduce the production cost of farmers, the present invention provides a self-priming well. The self-priming well uses the capillary principle to design a device that uses the pulling force generated by surface water evaporation and plant transpiration as the driving force to suck water up from the surface runoff layer and reach the roots of crops to automatically meet the water needed for crop growth.
