Soil screening remediation device

Abstract

The invention relates to the technical field of agricultural devices, in particular to a soil screening remediation device. The soil screening remediation device comprises a soil conveying belt, a soil taking shovel is mounted at the front end of the soil conveying belt, the rear end of the soil conveying belt is connected with a soil treatment tank, a film adsorption mechanism is mounted in the soil treatment tank, a screening device is mounted under the film adsorption mechanism, and a chemical spraying device is mounted below the spraying device and connected with a chemical storage tank through a delivery pipe. Through the soil screening remediation device, processes of soil turning, crushing, screening, chemical spraying, remediation and the like can be performed simultaneously, screening effect is good, mulching films and solid impurities can be removed effectively, and separation efficiency is high; the soil screening remediation device is simple in structure, chemical spraying holes in the chemical spraying device are arranged alternatively, chemical and soil are mixed more uniformly, time for soil impurity removal and remediation is short, and the remedied soil can be kept soft and highly breathable within a long time.

Description

technical field [0001] The invention relates to the technical field of agricultural devices, in particular to a soil screening and repairing device. Background technique [0002] Nowadays, PE film is often covered on the soil in agricultural planting, so as to increase the temperature of the soil, maintain the moisture in the soil, and effectively maintain the internal structure of the soil; it can also suppress salt and protect seedlings, improve the soil light and heat conditions, and make the crops hygienic and clean. In a word, plastic film mulching improves the supply capacity and balance capacity of the soil through the above-mentioned maintenance and adjustment of the soil, making it more resistant to pest invasion and microbial pests, improving the growth environment of plants and also improving the growth capacity of plants. [0003] However, with the increase in the use of mulch, the problems brought about by mulching have also come one after another. According to...
