Rice planting soil restoration device and method

Abstract

The invention relates to the technical field of agricultural machines, and discloses a rice planting soil restoration device. The rice planting soil restoration device comprises a device shell, a shovel plate is fixedly installed at the front end of the device shell, a conveying belt is movably installed on the lower portion of the interior of the device shell, a rotating rod is movably installedin the middle of the conveying belt, a first belt wheel is fixedly installed at one end of the rotating rod, a first belt is movably installed on one side of the interior of the first belt wheel, stirring blades are movably installed above the conveying belt, and rotating shafts are fixedly installed in the middles of the stirring blades. According to the rice planting soil restoration device andmethod, the shovel plate is fixedly installed at the front end of the device shell and is in a comb tooth shape, soil can be conveniently screwed up when the device moves on the soil, waste plastic films and plant root systems in the soil can be shoveled through the comb tooth shape, it is conveniently ensured that impurities in the soil are treated, and the soil is restored conveniently.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a rice planting soil restoration device and method. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants. Its thickness is generally about 2 meters. The soil not only provides mechanical support for plant growth, but also provides water, fertilizer, air, and heat for plant growth and development. Due to the rapid growth of population and rapid industrial development, solid wastes are continuously stacked and dumped on the soil surface, and harmful wastewater is continuously infiltrated into the soil, resulting in excessive heavy metal content in the soil and hindering the normal function of the soil. Technical measures to restore normal function of polluted soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies, and there are more than 1...

[0003] Greenhouses, also known as greenhouses, can transmit light, keep warm or heat, and are used to cultivate plants. In seasons that are not suitable for plant growth, greenhouses can increase the temperature to increase production. They are mostly used for temperature-loving vegetables, flowers, and trees in low-temperature seasons. However, because the greenhouse needs to fertilize the soil and spray pesticides all year round, most of the greenhouses are polluted, and there are plant roots and film fragments that need to be cleaned in the soil of the greenhouse. Greenhouse plowing mostly relies on manual removal of plant roots and mulch debris, which is inefficient

[0004] There are three repair directions for existing soil restoration devices, namely biological restoration, physical restoration and chemical restoration. The main method of chemical restoration is to prepare modifiers. The commonly used modifiers mainly include silicate, calcium carbonate, lime, etc., and then Put it into the soil to realize the adsorption of heavy metals, and form insoluble sediments through precipitation, reduction and other methods. Existing soil restoration devices only form insoluble sediments of heavy metals, which are not easy to be absorbed by plants, but there is still soil. At the same time, the soil cannot be fully mixed and reacted, and the heavy metals in the soil cannot be removed, and some existing soil restoration devices have complex structures, cumbersome operations, poor mobility, insufficient flexibility, and too frequent use. The effect is relatively general, and the treatment of harmful substances is not thorough enough, and only a single leaching of the soil can be carried out, which cannot meet the needs of development
