[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a drug delivery device for groundwater remediation and treatment, including a workbench 1, a liquid storage tank 2 is fixedly connected to the upper surface of the workbench 1, a motor 3 is fixedly connected to the outer wall of the liquid storage tank 2, a gear 4 is fixedly connected to the output end of the motor 3, a gear 2 5 is rotatably connected to one side of the upper surface of the workbench 1, a left-right symmetrical rotating drum 7 is rotatably connected inside the workbench 1, a belt 6 is arranged between the rotating drum 7 and the outer wall of the gear 2 5, an auger blade 8 is fixedly connected to the outer wall of the rotating drum 7, and a plurality of liquid The output ends of the hydraulic cylinder 9 are connected, the outer wall of the hydraulic cylinder 9 is fixedly connected to a fixed plate 10, and a cleaning assembly 11 is arranged on the upper surface of the fixed plate 10; the cleaning assembly 11 comprises a support frame 1101, the lower surface of the support frame 1101 is fixedly connected to the upper surface of the fixed plate 10, the lower surface of the support frame 1101 is fixedly connected to a cleaning brush 1102, the cleaning brush 1102 is slidably connected to the outer wall of the auger blade 8, and an arc-shaped scraper 1103 is fixedly connected to one side of the outer wall of the support frame 1101, and the outer wall of the arc-shaped scraper 1103 is slidably connected to the outer wall of the rotating drum 7;

[0023] Specifically, by starting the motor 1 3, the driving gear 1 4 and the gear 2 5 mesh with each other and rotate. This mechanical transmission method not only ensures the stability and continuity of the rotation, but also greatly improves the work efficiency. Through this mechanism, the drum 7 inside the belt 6 can rotate smoothly, thereby realizing the mixing and discharge of the soil. When the hydraulic cylinder 9 is started, the workbench 1 will steadily descend until it completely enters the soil. At this time, the drum 7, driven by the motor, effectively discharges the soil through the auger blade 8 to ensure the continuous operation process. When the workbench 1 completes the operation and is ready to rise, the auger blade 8 will continue to rotate on the inner wall of the fixed plate 10. At this time, the cleaning brush 1102 will closely fit the outer wall of the auger blade 8 for friction, effectively removing the soil attached to the surface. This design not only ensures the cleanliness of the auger blade 8, but also extends its service life. When the drum 7 rotates, the arc scraper 1103 will rub the outer wall of the drum 7, especially the discharge port. This design cleverly solves the problem of easy blockage and soil residue at the discharge port, ensuring the continuity and efficiency of soil treatment.

[0024] Reference Figure 1 - Figure 3 The outer wall of the liquid storage tank 2 is fixedly connected with a bracket 12, the inner wall of the bracket 12 is fixedly connected with a motor 2 13, and the output end of the motor 2 13 is fixedly connected with a gear 3 14; the liquid storage tank 2 is rotatably connected with a left-right symmetrical rotating shaft 15, and the outer wall of the rotating shaft 15 is fixedly connected with a stirring blade 16; the other side of the outer wall of the rotating shaft 15 is fixedly connected with a gear 4 17, and the gear 4 17 is meshed and connected with the gear 3 14; a discharge pipe 18 is opened through the lower side of the liquid storage tank 2, and a solenoid valve 19 is fixedly connected to the outer wall of the discharge pipe 18, and the outlet of the discharge pipe 18 is arranged at the inlet of the gear 4 17; a visual window 20 is arranged through the inside of the liquid storage tank 2, and a scale line 21 is fixedly connected to the outer wall of the visual window 20; a hopper 22 is fixedly connected to the upper surface of the liquid storage tank 2;

[0025] Specifically, first, the required medicine is placed inside the liquid storage tank 2. The liquid storage tank is made of corrosion-resistant materials to ensure that the medicine will not react chemically with the container during storage. At the same time, the liquid storage tank is also equipped with a liquid level sensor to monitor the remaining amount of the medicine in real time. When the medicine is lower than the set threshold, the system will automatically sound an alarm to remind the staff to replenish the medicine in time. Then, by starting the motor 2 13, the gear 3 14 and the gear 4 17 are driven to mesh and rotate. In this process, the stirring blade 16 will rotate accordingly, generating a strong stirring force to evenly stir the medicine in the liquid storage tank 2. The purpose of stirring is to ensure that the components in the medicine are fully mixed to avoid the problem of uneven concentration during the delivery process. After the medicine is evenly stirred, the medicine inside the liquid storage tank 2 is transmitted into the inside of the drum 7 through the discharge pipe 18 by opening the solenoid valve 19. The opening and closing of the solenoid valve are precisely controlled by the control system to ensure that the amount and speed of the medicine are in accordance with the preset requirements. At the same time, the design of the discharge pipe also fully considers the flow characteristics of the fluid to ensure that the medicine can smoothly enter the drum. Finally, the reagent is transmitted to the groundwater through the discharge port inside the drum 7 to achieve the treatment effect. The design of the drum takes into account the flow characteristics of groundwater and the diffusion requirements of the reagent, ensuring that the reagent can be evenly dispersed in the groundwater body to achieve the expected treatment effect. At the same time, the rotation speed and the amount of the drum can also be adjusted according to actual needs to meet the treatment needs in different scenarios.

[0026] Working principle: when it is necessary to use the agent delivery device for groundwater repair and treatment, at this time, by starting the motor 13, the motor 13 drives the gear 14 to mesh and rotate with the gear 2 5, so as to facilitate the rotation of the drum 7 inside the belt 6, and at the same time, by starting the hydraulic cylinder 9, the workbench 1 is lowered into the soil for use, and the auger blade 8 is driven by the drum 7 to discharge the soil. When the workbench 1 rises, the auger blade 8 will rotate on the inner wall of the fixed plate 10, and the cleaning brush 1102 will rub the outer wall of the auger blade 8, so as to facilitate the cleaning of the surface soil, and at the same time, the arc scraper 1103 will rub the outer wall of the drum 7, so as to achieve the effect of cleaning the surface soil of the discharge port of the drum 7;

[0027] Secondly, when it is necessary to add medicine to the groundwater, the medicine is placed inside the liquid storage tank 2. At this time, by starting motor 2 13, motor 2 13 drives gear 3 14 and gear 4 17 to engage and rotate, thereby driving the stirring blade 16 to evenly stir the medicine. At this time, by opening the solenoid valve 19, the medicine inside the liquid storage tank 2 is transmitted into the inside of the rotating drum 7 through the discharge pipe 18. At this time, the medicine will be transmitted to the inside of the groundwater through the discharge port inside the rotating drum 7 to achieve the effect of treatment.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
