Problems solved by technology

When the improver is evenly sprinkled in the soil, it is necessary to use special spreading equipment. The current sprinkler setting is generally relatively simple, and it is generally carried out by oscillating the material. This method has a good effect on the spread of the improver Poor, affects the thoroughness and uniformity of soil improvement

Abstract

The invention discloses a feeding device of improvement agent for soil heavy metal prevention and control, which can accurately control the feeding rate of the improvement agent, so that the feeding is uniform and reliable, meanwhile, the improvement agent can be uniformly fed in the feeding process, and the heavy metal improvement agent can be uniformly fed into the soil by using a sprinkling assembly. The device can greatly improve the feeding effect of the heavy metal improvement agent and ensure the improvement uniformity of the soil. The thoroughness in improvement of the soil is achieved. The reliability and stability of the feeding are ensured by means of up-and-down vibration for feeding and left-and-right vibration for mixing the material to be uniform.

Description

technical field [0001] The invention relates to a feeding device for soil heavy metal prevention and improvement agent, and belongs to the technical field of soil heavy metal prevention and control equipment. Background technique [0002] Soil heavy metal pollution is due to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive deposition causes soil pollution. Especially in recent years, due to the addition of metals to the soil due to human activities, the heavy metals in the soil are significantly higher than the original content, and the quality of the ecological environment has deteriorated. The heavy metals that pollute the soil mainly include mercury (Hg), cadmium (Cd), lead (Pb), chromium (Cr) and metalloid arsenic (As) and other elements with significant biological toxicity, as well as zinc (Zn) and copper with certain toxicity. (Cu), nickel (Ni) and other elements. Mainly come from pesticides, wastewater...
