Description

Technical Field

[0001] This utility model relates to the field of contaminated soil treatment technology, specifically to a contaminated site soil remediation device. Background Technology

[0002] Soil pollution affects the growth of plants on the soil surface, therefore soil remediation is a powerful means to solve soil pollution problems.

[0003] When the soil pollution level is relatively low, soil remediation can usually be achieved by sampling and spraying pesticides. However, when the soil pollution level is relatively high, the soil is usually placed in a mixing tank so that the pesticides are mixed with the contaminated soil to achieve the soil remediation effect.

[0004] The mixing and homogenization of the pesticide and soil is a crucial step, requiring a high degree of uniformity. Furthermore, insufficient soil fragmentation leads to inadequate integration of the soil with the stabilizing agent, impacting the remediation effect. Therefore, remediation treatment of contaminated soil is necessary to reduce pollutant concentrations to acceptable levels, improve nutrient deficiencies in urban plants, and lay a solid foundation for their healthy growth.

[0005] In the prior art, such as Chinese patent application number 202120251988.4, authorization announcement number CN214441812U, entitled "A Soil Remediation Treatment for Garden Maintenance", the above patent discloses a soil remediation treatment device for garden maintenance, including a box body, a support plate fixedly connected to the lower surface of the box body, a caster wheel fixedly connected to the lower surface of the support plate, a soil inlet box and a feed box fixedly connected to the upper surface of the box body, and a right-angle plate slidably connected to the side of the feed box.

[0006] This soil remediation treatment device for garden maintenance uses a transmission rod and a mixing rod to disperse the soil inside the tank, and a right-angle plate to control the flow rate of the remediation material, thus achieving the effect of ease of use. However, in existing technologies such as the aforementioned patent, the soil inside the mixing tank is mixed by rotating the mixing rod. But in actual use, the soil inside the tank can only rotate horizontally, which leads to poor mixing effect between the soil and the agent, and has certain shortcomings. Utility Model Content

[0028] 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.

[0029] Please see Figures 1-7 This utility model provides a technical solution: a soil remediation treatment device for contaminated sites, including a treatment frame 1, a mixing cylinder 2 rotatably connected to the treatment frame 1, and a stirring unit rotatably connected to the mixing cylinder 2. The stirring unit includes a stirring rod 6 rotatably connected to the treatment frame 1. The treatment frame 1 is provided with a power mechanism for driving the stirring rod 6 to rotate inside the mixing cylinder 2. The power mechanism and the mixing cylinder 2 are connected by a linkage to drive the mixing cylinder 2 to reciprocate on the treatment frame 1.

[0030] Specifically, the contaminated site soil remediation treatment device includes a treatment frame 1, on which a mixing drum 2 is rotatably connected. During operation, the mixing drum 2 contains soil and various chemical agents. A stirring unit is also rotatably connected to the mixing drum 2, including a stirring rod 6 rotatably connected to the treatment frame 1. In use, the stirring rod 6 rotates inside the mixing drum 2, mixing the soil and various agents entering the mixing drum 2 to meet operational requirements. The treatment frame 1 is equipped with a power mechanism to drive the stirring rod 6 to rotate inside the mixing drum 2, providing power for the rotation. The power mechanism and the mixing drum 2 are connected via a linkage, causing the mixing drum 2 to reciprocate on the treatment frame 1, thus causing the soil and various chemical agents inside the mixing drum 2 to also rotate. Therefore, during use, the power mechanism is activated, which drives the stirring rod 6 to rotate inside the mixing drum 2, stirring the soil and various chemical agents inside the mixing drum 2. This improves the uniformity of the soil and various chemical agents during mixing. During the stroke of the stirring mechanism, the mixing drum 2 is driven to rotate on the processing frame 1 through the linkage, so that the soil and various chemical agents will be turned and stirred along with the mixing drum 2, thereby further improving the uniformity of the soil and various chemical agents and achieving better results.

[0031] In the embodiments provided by this utility model, the power mechanism includes a power rod 7 rotatably connected to the processing frame 1, and a servo motor 10 is also provided on the processing frame 1. The servo motor 10 is coaxially connected to the power rod 7, and the stirring rod 6 is connected to the power rod 7 through a synchronization component 8. Specifically, the synchronization component 8 is existing technology and can be a pulley assembly, a timing belt assembly, etc., which will not be described in detail here. During use, the servo motor 10 rotates, driving the power rod 7 to rotate, which in turn drives the stirring rod 6 to rotate through the synchronization component 8, so that the stirring rod 6 rotates inside the mixing cylinder 2 to meet the working requirements.

[0032] In the embodiments provided by this utility model, the linkage includes a linkage rod 11 rotatably connected to the processing frame 1, and a drive unit for driving the mixing cylinder 2 to rotate is provided on the linkage rod 11; an intermittent gear 9 is installed on the power rod 7, and a transmission gear 14 is also provided on the linkage rod 11. The intermittent gear 9 and the transmission gear 14 mesh intermittently. The drive unit includes a linkage gear 12 fixedly connected to the linkage rod 11, and a gear ring 13 is fixedly connected to the mixing cylinder 2. The linkage gear 12 meshes with the gear ring 13. In the embodiments provided by this utility model, a return spring is provided between the linkage rod 11 and the processing frame 1. During use, the servo motor 10 rotates, driving the power rod 7 to rotate. When the power rod 7 rotates, it drives the intermittent gear 9 to rotate, which in turn drives the linkage rod 11 to rotate through the transmission gear 14, so that the linkage gear 12 drives the gear ring 13 to rotate, thereby driving the mixing cylinder 2 to rotate. When the intermittent gear 9 does not mesh with the transmission gear 14, the return spring, in the process of restoring its elastic deformation, drives the mixing cylinder 2 to rotate in the opposite direction. The mixing process is repeated, and the rotation of the mixing drum 2 drives the soil and various chemical agents inside the mixing drum 2 to mix, thereby greatly improving the mixing efficiency of the mixing drum 2.

[0033] In the embodiments provided by this utility model, multiple sets of stirring blades 15 are fixedly connected to the stirring rod 6 to further improve the uniformity of the mixing of the soil and various chemical agents.

[0035] In the embodiments provided by this utility model, the mixing drum 2 is provided with a feeding channel 3 and a discharging channel 4, and both the feeding channel 3 and the discharging channel 4 are provided with control valves to facilitate the feeding and discharging of the mixing drum 2.

[0036] In the embodiments provided by this utility model, the inside of the mixing cylinder 2 is conical, which facilitates the discharge of materials after the mixing operation of the mixing cylinder 2 is completed, thus meeting the work requirements.

[0037] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.
