Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 4This utility model provides a technical solution: a heavy metal soil remediation device, including a remediation box 1 with an open bottom, a soil loosening spraying mechanism 200 installed inside the remediation box 1, a push rod 301 fixedly installed on the left side of the remediation box 1, two support plates 302 fixedly installed on the outside of the remediation box 1, two universal wheels 303 fixedly installed at the bottom of the support plates 302, and a portable power supply 4 detachably connected to the top of the left support plate 302; by using the soil loosening spraying mechanism 200 inside the remediation box 1, the soil conditioner can be sprayed directly into the deep soil, so that the soil conditioner can move in the soil along with the soil loosening structure, which facilitates the improvement of the soil conditioner's remediation effect on deep soil, making the soil conditioner's remediation effect on heavy metal soil relatively good, and convenient for rapid remediation and then for use in the planting of Chinese medicinal herbs, thereby effectively improving the practicality of the heavy metal soil remediation device.
[0026] In this embodiment, the soil loosening spraying mechanism 200 is a structure used to drill and loosen the soil in the heavy metal-affected soil that needs to be treated.
[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the soil loosening and spraying mechanism 200 includes a hydraulic cylinder 201 fixed to the top of the treatment box 1. The piston end of the hydraulic cylinder 201 penetrates the top of the treatment box 1 and is fixedly mounted with a movable plate 202. The bottom of the movable plate 202 is rotatably connected to six drill rods 203 via bearings. Spiral blades 204 are fixed to the outside of the drill rods 203. The top of the drill rods 203 is rotatably connected to a positioning tube 205 via bearings. The top end of the positioning tube 205 penetrates the top of the treatment box 1 and is fixed with a corrugated pipe 206. The front of the treatment box 1... A fixing plate 207 is fixed on both the front and back sides. A water tank 208 is fixed on the top of the fixing plate 207. A small water pump 209 connected to the inside of the corrugated pipe 206 is also installed on the corrugated pipe 206. A conveying chamber 210 is opened inside the drill rod 203. A water outlet chamber 211 connected to the corresponding conveying chamber 210 is opened inside the drill rod 203. Several nozzles 212 are installed through and fixed on the outside of the drill rod 203. The soil loosening spraying mechanism 200 also includes a drive assembly for driving the drill rod 203 to rotate.
[0028] The drive assembly includes a synchronous pulley 213 fixed to the outside of the drill rod 203, a synchronous belt 214 meshing and driving between the outer sides of two corresponding synchronous pulleys 213, three mounting boxes 215 fixed to the bottom of the moving plate 202, a servo motor 216 fixedly mounted on the inner bottom wall of the mounting box 215, a drive gear 217 fixedly mounted on the output shaft of the servo motor 216, and a driven gear 218 fixedly mounted on the outer side of the front drill rod 203.
[0029] It should be noted that, as Figure 2As shown, the top of the drill rod 203 penetrates the top of the moving plate 202, the synchronous pulley 213 is located above the moving plate 202, and the six drill rods 203 are arranged in pairs. The outer side of the driving gear 217 and the outer side of the corresponding driven gear 218 mesh with each other, so that the driving gear 217 can drive the driven gear 218 to rotate, thereby causing the drill rod 203 to rotate. Under the cooperation between the synchronous pulley 213 and the synchronous belt 214, the drill rod 203 on the back side rotates, thus completing the power transmission.
[0030] In addition, the spiral blade 204 is located below the mounting box 215, so that the spiral blade 204 can be rotated normally by the drill rod 203, which can be used to loosen the soil during the rotation. The top of the drill rod 203 will not contact the inner wall of the treatment box 1 during the lifting and lowering process driven by the hydraulic cylinder 201, so that it can move up and down normally. The bottom end of the positioning tube 205 penetrates the treatment box 1 and the corresponding drill rod 203 and extends into the interior of the corresponding conveying chamber 210 and is connected to the interior of the corresponding water outlet chamber 211, so that the liquid in the positioning tube 205 can be transported into the interior of the water outlet chamber 211.
[0031] Meanwhile, the input end of the small water pump 209 passes through the top of the corresponding water tank 208 and extends into its interior. Each water tank 208 has three small water pumps 209 fixed on its top, so that the small water pumps 209 can extract and transport the liquid in the water tank 208 through the corrugated pipe 206. The outside of the drill rod 203 is provided with several embedded grooves for inserting several nozzles 212. The input end of the nozzle 212 extends into the interior of the corresponding water outlet chamber 211, so that the liquid inside the water outlet chamber 211 can be sprayed out through the nozzle 212 after being pressurized by the re-entered liquid. Under the action of the embedded groove, the protrusion of the nozzle 212 on the outside of the drill rod 203 can be reduced, so that the drill rod 203 can smoothly drill holes in the soil.
[0032] The working principle of the above embodiments is as follows:
[0033] When treating soil for planting medicinal herbs, the soil conditioner is injected into the water tank 208 according to the type of heavy metal soil. This moves the treatment tank 1, activates the hydraulic cylinder 201, and moves the moving plate 202 downward, allowing the drill rod 203 to be inserted into the ground. The servo motor 216 is activated, which drives the driven gear 218 to rotate through the drive gear 217, causing the drill rod 203 to rotate. Under the action of the spiral blades 204, the surrounding soil is loosened. The small water pump 209 is activated, allowing the soil conditioner to be delivered through the corrugated pipe 206 to the positioning pipe 205, then through the positioning pipe 205 into the delivery chamber 210, and finally filling the water outlet chamber 211 before being sprayed out through the nozzle 212. This allows the soil conditioner to be sprayed into different depths of the soil according to the depth of the drill bit insertion, enabling the soil conditioner to effectively act on the deep soil for treatment.
[0034] Compared with existing technologies, this heavy metal soil remediation device, through the use of the soil loosening and spraying mechanism 200 inside the treatment box 1, allows the soil conditioner to be sprayed directly into the deep soil. This enables the soil conditioner to move within the soil along with the loosened soil structure, improving the treatment effect of the soil conditioner on deep soil. This results in a superior treatment effect of the soil conditioner on heavy metal soil, facilitating rapid treatment and subsequent use for medicinal herb cultivation. Thus, it effectively enhances the practicality of the heavy metal soil remediation device and solves the problem that existing heavy metal contaminated soil remediation devices are inconvenient to allow the soil conditioner to directly act on the deep soil during actual use.
