Pre-buried slow-release soil water-retaining agent feeding device

Abstract

The invention discloses an embedded slow-release soil water-retaining agent feeding device, which belongs to the technical field of soil remediation. The device comprises an upper soil box and an inner soil box, the upper soil box is fixedly mounted at the top end of the inner soil box, and a guide hole is dug in the outer wall of the bottom of the upper soil box. The guide holes penetrate throughthe outer wall of the top of the soil inner box and communicate with the interior of the soil inner box, and the outer wall of the top of the soil upper box is in threaded connection with a screw. The water-retaining agent can be automatically fed in an embedded mode when soil moisture is lost and caked, operation is easy and the feeding efficiency is high; before the water-retaining agent permeates into soil, water is supplemented to wet the soil, the effect of the water-retaining agent is improved and only clear water needs to be added regularly; and when the water-retaining agent loses efficacy and the soil moisture loses and is caked again, the water-retaining agent can be automatically fed again, so that the device can be repeatedly used for multiple times, and the feeding efficiencyis further improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, and more specifically, to a pre-embedded slow-release soil water-retaining agent delivery device. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and carried out plans for the treatment and restoration of contaminated soil, thus forming a new soil restoration industry. [0003] With the increasing environmental pollution and the decrease of green vegetation year by year, it poses a severe test to the human living environment, especially in the fields of agricultural production and ur...

Problems solved by technology

[0004] Adding water-retaining agent is a common method for soil water loss control. After being put in, the water-retaining agent is easy to gradually lose and become invalid with the penetration of water in the soil. Therefore, it is necessary to add a water-retaining agent every once in a while. In the prior art, The addition of water retaining agent is very troublesome, the steps are cumbersome, the efficiency is low and the effect is poor, and the addition of water retaining agent is mostly one-time injection, and the second injection needs to repeat complicated process operations
