Description

A layered percolator

technical field

The utility model relates to the technical field of water-saving irrigation, in particular to a layered seepage irrigation device. the

Background technique

As early as the 1950s, Comrade Mao Zedong put forward the slogan "Water conservancy is the lifeblood of agriculture". Today, in the face of the growing demand for a large amount of water for agricultural products and the contradiction of fresh water shortage, if it cannot be resolved in a timely manner, it will seriously restrict my country's agriculture. and even the development of the entire national economy. Since the 1980s, a large number of water-saving agricultural irrigation technologies have been developed successively at home and abroad: sprinkler irrigation, drip irrigation, infiltration irrigation, etc. Sprinkler irrigation is an irrigation method that uses special piping systems and equipment to send pressurized water to the irrigation area and spray it into the air to form fine water droplets and sprinkle it on the field; drip irrigation is to filter water with a certain pressure through the pipe network and outlet pipes ( Drip irrigation belt) or dripper slowly drips into the soil near the plant roots in the form of water droplets; compared with sprinkler irrigation and drip irrigation, which have low water resource utilization and affect ground cultivation, etc., infiltration irrigation is to integrate the pipeline system and infiltration The head is buried at 30-60 cm underground. It does not affect the ground cultivation, prevents the evaporation of water on the surface, and can supply water to the root layer of crops in a timely and appropriate amount according to the needs of the crops. It saves more than 50% of water than ground irrigation, but Since the plant rhizomes grow vertically or horizontally underground, the water and nutrients required by each layer are different, and the absorption efficiency of roots in each layer is also different, so the water saving efficiency can still be improved. The backflow of sediment into the pipe, the water orientation of the root system of crops, and the condensation of minerals in the water can all paralyze the infiltration irrigation system and lose the irrigation ability. The Chinese patent "Water-Saving Irrigation Device" (application number: 02235892.7) discloses a water-saving irrigation device, which uses a number of mesh-shaped seepage holes on the sleeve outside the irrigation pipe to supply water to plants. It is simple, but it has no filtering effect on water, and it is easy to be blocked by sediment. At the same time, stratification and water supply are not considered, and the water saving efficiency needs to be improved. the

Utility model content

The purpose of the invention of this utility model is to provide a simple structure, which can be conveniently inserted into the soil next to the plant, purifies and filters the irrigation water, and transports it to each layer of the plant roots according to the amount, so as to meet the different water and nutrient absorption requirements of each layer of the plant. layered percolators. the

In order to achieve the above object, the utility model adopts the following technical solutions: a layered seepage irrigation device, including a seepage irrigation main body, a ground plug connected with the seepage irrigation main body, the ground plug is provided with a seepage hole, and the seepage pipe of the seepage irrigation main body is connected with the main body of the seepage irrigation system. A filter layer is arranged between the ground plugs. the

Preferably, the filtering layer is one or more of fiber layer, fine sand layer and sponge layer superimposed. the

Preferably, the ground insert is in the shape of a long cone or a long cylinder. the

Preferably, the irrigation main body is provided with several water inlet and outlet holes. the

Preferably, the ground insertion surface is engraved with a scale indicating the insertion depth. the

Preferably, the ground-inserted seepage holes are distributed increasing from top to bottom, or distributed decreasingly from wound to bottom, or evenly distributed. the

In the above solution, further, the irrigation main body is screwed or has an interference fit with the ground. the

Compared with the prior art, the utility model has the beneficial effects of: convenient use, scientific water supply, single or multiple irrigation devices can be inserted into the soil around any plants that need to be irrigated, so as to realize water supply or nutrients at any time, At the same time, according to the different needs and abilities of each layer of the underground roots of plants to absorb water, the water is supplied in layers and in reasonable quantities, and it is easy to grasp the precise depth of water application; the effective utilization rate of water is high. The whole process is carried by water pipes, directly into the soil of each layer of plant rhizomes, without ground runoff, effectively reducing the ineffective evaporation of soil moisture, meeting the water needs of roots and hairs of different layers of plants, and at the same time refining the water flow, and gradually wetting by the capillary action of the soil Soil, make the soil loose, not hard, and easy to absorb by roots; low cost, long service life. The utility model is low in cost, does not require large-scale earth-breaking construction, does not need to be buried in advance, and can be filled with different filter materials according to needs. In addition to effectively filtering impurities in water, the utility model can also store water, prevent waterway from being blocked, and ensure smooth seepage channels. the
