Soil screening device for soil remediation

Abstract

The invention discloses a soil screening device for soil restoration, which belongs to the field of soil restoration. The device comprises: a crushing assembly, which is used for crushing materials, and a screening box, which is arranged under the crushing assembly, and the screening box For material screening, the side wall of the crushing assembly is connected to the upper end of the screening box through the first discharge pipe, and the crushed material is sent into the screening box, and the screening box is provided with a screening base. The invention realizes the The soil is effectively screened and screened evenly, the screen is not easy to be blocked, the dust in the soil screening environment can be controlled, and the energy consumption and resources used for soil treatment can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of soil restoration, and in particular relates to a soil screening device for soil restoration. Background technique [0002] The descriptions in this section merely provide background information related to the disclosure in this application and may not constitute prior art. [0003] 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 soil light and heat conditions, and make 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 capaci...

AI Technical Summary

Problems solved by technology

[0004] However, with the increase in the use of mulch film, the problem of mulch film remaining in the soil will appear. The mulch film remaining in the soil will affect the germination and growth of crops, and it will also affect the transfer of nutrients and water, and affect the growth of crop roots. It is very large and the yield is low; similarly, the residual mulch film on the farmland will also lead to the deterioration of the soil environment, the decrease of soil moisture content, weaken the ability to resist drought, cause soil compaction, and affect the growth of crops, and other debris residues are more likely to appear in the soil, such as garbage bags , cigarette butts and other sundries

[0005] However, the existing soil sieving device has the problems of uneven sieving and high energy consumption when sieving the soil.
