Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to an electric deep tillage remediation device for soil heavy metal pollution. Background Technology

[0002] With the acceleration of industrialization and urbanization, the discharge of large amounts of industrial wastewater, exhaust gas, and waste residue containing heavy metals, as well as the unreasonable use of pesticides and fertilizers in agricultural production, have led to increasingly serious heavy metal pollution problems in arable land. Heavy metals such as mercury, cadmium, lead, chromium, and arsenic are toxic, cumulative, and difficult to degrade. They not only affect soil fertility and ecological functions but also enter the human body through the food chain, posing a potential threat to human health.

[0003] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles of contaminated soil remediation can include: altering the form in which pollutants exist in the soil or their binding method, reducing their mobility and bioavailability in the environment; and reducing the concentration of harmful substances in the soil.

[0004] In soil remediation, it is necessary to till the soil by turning over the deep, uncontaminated soil to the surface layer and mixing it with the surface contaminated soil. This reduces the relative content of heavy metals in the surface soil, while improving the soil's physical structure, increasing soil aeration and permeability, and promoting the natural degradation and migration of heavy metals in the soil.

[0005] The existing method of spraying soil conditioner unevenly during soil tillage leads to inconsistent soil improvement effects during subsequent soil remediation, resulting in uneven nutrient distribution and uneven improvement of soil structure, which affects the effectiveness of soil remediation. Based on this, this application proposes an electric deep tillage remediation device for soil heavy metal pollution, which can solve the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electric deep tillage remediation device for soil heavy metal pollution.

[0007] The purpose of this utility model is achieved through the following technical solution: an electric deep tillage remediation device for soil heavy metal pollution, comprising a frame, which is U-shaped in shape. Multiple spline shafts driven by motors are evenly arrayed on the front side of the frame. Each spline shaft is equipped with a lifting seat that can move up and down. Multiple cylindrical plates are installed below the lifting seats to form multiple tillage cylinders. Spiral plates are installed on the inner walls of the tillage cylinders. A medicine tank is installed on the rear side of the frame.

[0008] Optionally, drive wheels are installed at the four corners of the bottom of the frame.

[0009] Optionally, the top surface of the frame is equipped with multiple telescopic motors, the output ends of which overlap with the top surfaces of multiple lifting seats respectively, and springs are fitted on multiple splined shafts, all of which are located below the lifting seats.

[0010] Optionally, the bottom wall of the medicine box is provided with multiple uniformly arranged medicine dispensing ports.

[0011] Optionally, the bottom of each of the multiple cylindrical plates is equipped with a multiple uniformly arrayed tooth.

[0012] This utility model has the following advantages:

[0013] This electric deep tillage remediation device for soil heavy metal pollution uses a U-shaped frame as its main body. Inside the frame, on the front side, are multiple splined shafts that rotate via motors. Each shaft has a lifting seat that can move up and down. On the bottom of the lifting seats are multiple circularly arrayed cylindrical plates. Spiral plates are installed on the inner walls of the cylindrical plates, and multiple teeth are installed below the cylindrical plates. During use, the tillage depth can be changed by adjusting the vertical position of the lifting seats. As the cylindrical plates rotate, the teeth break up the soil, and the spiral plates turn the soil, thereby achieving deep tillage and turning of the soil.

[0014] A medicine tank is installed on the rear side inside the frame, and its bottom wall has multiple evenly arrayed medicine outlets, so that the repair agent can be evenly sprinkled onto the soil. Attached Figure Description

Multiple splined shafts 6 driven by motors 3 are evenly arranged on the front side of the frame 1. Each splined shaft 6 is equipped with a lifting seat 2 that can move up and down. Multiple cylindrical plates 10 are installed below the lifting seats 2, forming multiple tillage cylinders. Spiral plates 11 are installed on the inner walls of the tillage cylinders. A medicine tank 8 is installed on the rear side of the frame 1.

[0024] As an optional technical solution of this utility model, drive wheels 5 are installed at the four corners of the bottom of the frame 1, which enables the movement of the entire device to facilitate operation by the staff.
