Description

Technical Field

[0001] This utility model relates to the technical field of passivating agent spraying devices, and more specifically to a passivating agent spraying device for farmland soil remediation. Background Technology

[0002] Soil remediation primarily aims to restore contaminated soil by fixing, transferring, absorbing, degrading, or transforming pollutants within it. With my country's continuous urbanization and industrialization, urban sludge and waste are entering agricultural ecosystems, exacerbating heavy metal pollution in soil. Heavy metal-contaminated farmland requires passivating agents for remediation. Chemical passivation involves applying various passivating agents to contaminated soil, utilizing mechanisms such as adsorption, precipitation, redox reactions, and complexation to alter the form and activity of pollutants, transforming them into inactive components that are difficult for plants to absorb, thus achieving remediation and utilization. To improve the effectiveness of passivation, spraying devices are typically used to evenly disperse the passivating agent throughout the farmland.

[0003] For example, in the prior art disclosure CN218049635U, a cadmium passivating agent spraying device for soil remediation can drive the drive shaft to rotate the linkage shaft of the corner mechanism when the trolley is pushed for spraying. This drives the arc gear to rotate, and finally, through the transmission of the linkage gear, the metal tube rotates and drives the torsion spring to twist. When the arc gear is disconnected from the linkage gear, the torsion spring resets and drives the metal tube to rotate in the opposite direction, thereby realizing the reciprocating rotation of the nozzle and increasing the spraying range.

[0004] However, the existing technology has the following problems in use: traditional passivating agent spraying devices cannot quickly determine the wind direction, causing the passivating agent sprayed from the nozzle to be blown away by the wind before it even comes into contact with the farmland soil, resulting in waste of passivating agent and reduced spraying efficiency. Based on this, the present invention provides a farmland soil remediation passivating agent spraying device with high spraying efficiency. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a farmland soil remediation passivating agent spraying device. By setting a vertical rod and a cloth strip on a movable base, it is easy to quickly determine the wind direction. A rotating disk drives the storage tank and the nozzle to rotate, so that the nozzle faces the direction of the cloth strip's movement. Then, a linear module drives the nozzle to descend close to the farmland ground for spraying. This can increase the deposition of the passivating agent and reduce waste, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a farmland soil remediation passivating agent spraying device, comprising a movable base, a rotating disk on the top of the movable base, a storage tank fixedly mounted on the top of the rotating disk, an installation groove at the front end of the storage tank, a linear module fixedly mounted inside the installation groove, a nozzle fixedly mounted on the linear module, the nozzle and the storage tank being connected by a material conveying assembly, a vertical rod fixedly mounted on one side of the top of the movable base, a cloth strip fixedly mounted on the vertical rod, a sealing cover fixedly mounted on the top of the storage tank, and a stirring assembly mounted on the sealing cover for stirring the passivating agent to maintain its activity.

[0007] In a preferred embodiment, a first motor is fixedly installed at the bottom of the movable base. The top end of the output shaft of the first motor is fixed to the bottom of the rotating disk. The rotating disk is driven by the first motor to rotate, thereby realizing the automatic adjustment of the nozzle, which is more time-saving and labor-saving to use.

[0008] In a preferred embodiment, the material delivery assembly includes a suction pump, which is fixed to the outer wall of the storage tank. The inlet of the suction pump is connected to the inside of the storage tank through an inlet pipe, and the outlet of the suction pump is connected to the inside of the nozzle through an outlet pipe. The suction pump automatically delivers the passivating agent, thereby improving the spraying efficiency.

[0009] In a preferred embodiment, the stirring assembly includes a second motor, which is fixed at the center of the top of the sealing cover. A stirring paddle is fixed at the bottom of the output shaft of the second motor. The second motor drives the stirring paddle to rotate continuously, stirring the passivating agent inside the storage tank. This keeps the passivating agent active and improves the soil's absorption of the passivating agent.

[0010] In a preferred embodiment, a filter screen is fixedly installed inside the liquid inlet pipe, and the liquid inlet pipe is located on one side of the agitator to facilitate the quick replenishment of passivating agent by the operator.

[0011] In a preferred embodiment, a feeding hopper extends through one side of the top of the sealing cap, the feeding hopper being in communication with the interior of the storage tank, and a threaded cap is threadedly connected to the top of the feeding hopper. After feeding is completed, the threaded cap is tightened again to prevent the passivating agent inside the storage tank from being contaminated.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model uses a vertical rod and a cloth strip on a movable base to facilitate quick determination of wind direction. A rotating disk drives the storage tank and nozzle to rotate, so that the nozzle faces the direction of the cloth strip's movement. Then, a linear module drives the nozzle to descend and approach the farmland ground for spraying. This can increase the deposition of passivating agent and reduce waste.

[0014] 2. The second motor drives the stirring paddle to rotate continuously, stirring the passivating agent inside the storage tank. This keeps the passivating agent active and prevents lumpy passivating agent from clogging the suction pump and nozzle, thus affecting the spraying operation. Attached Figure Description

[0023] 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.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a farmland soil remediation passivation agent spraying device, including a movable base 1, a rotating disk 2 on the top of the movable base 1, and a first motor 12 fixedly installed at the bottom of the movable base 1. The top end of the output shaft of the first motor 12 is fixed to the bottom of the rotating disk 2, and the rotating disk 2 is driven to rotate by the first motor 12 to improve the adjustment efficiency.

[0025] The rotating disk 2 is fixedly provided with a storage tank 3. The front end of the storage tank 3 is provided with an installation groove 4. A linear module 5 is fixedly provided inside the installation groove 4. The linear module 5 is a mechanical transmission device that realizes precise linear motion. It drives the transmission component (ball screw or synchronous belt) to drive the slider to move precisely along the guide rail. A nozzle 6 is fixedly provided on the linear module 5.

[0026] The nozzle 6 and the storage tank 3 are connected by a conveying assembly 7. Specifically, the conveying assembly 7 includes a suction pump 71, which is fixed on the outer wall of the storage tank 3. The inlet of the suction pump 71 is connected to the inside of the storage tank 1 through an inlet pipe 72, and the outlet of the suction pump 71 is connected to the inside of the nozzle 6 through an outlet pipe 73. The suction pump 71 is a mechanical device that draws, transports, or transfers fluids (such as liquids, gases, semi-fluids, etc.) by generating negative pressure (suction). By utilizing the internal structural movement of the pump, a negative pressure is formed inside the pump chamber. Under the action of external atmospheric pressure, the fluid is "drawn" into the pump and then discharged or transported to the target location through the action of impellers, pistons, and other components.

[0027] A vertical rod 8 is fixedly installed on one side of the top of the mobile base 1, and a cloth strip 9 is fixedly installed on the vertical rod 8. A sealing cover 10 is fixedly installed on the top of the storage tank 3. After the spraying work is completed, the staff can remove the sealing cover 10 from the storage tank 3 and then clean the inside of the storage tank 3 to prevent passivating agent residue.

[0028] In actual use, the staff first judges the wind direction based on the cloth strip 9 on the vertical pole 8. Then, the first motor 12 drives the storage tank 3 on the rotating disk 2 to rotate. After the storage tank 3 drives the nozzle 6 to rotate and approach the direction of the cloth strip 9, the linear module 5 drives the nozzle 6 to descend and approach the farmland ground. Then, the suction pump 71 sucks the passivating agent in the storage tank 3. The passivating agent is sprayed from the nozzle 6 onto the ground and mixes with the soil for repair. When the wind direction changes, the rotating disk 2 drives the storage tank 1 to rotate, thereby automatically adjusting the orientation angle of the nozzle 6 to prevent the sprayed passivating agent from being directly blown away by the wind, thereby increasing the deposition of the passivating agent and reducing waste.

[0029] Refer to the instruction manual appendix Figures 1-3 The sealing cap 10 is provided with a stirring assembly 11 for stirring the passivating agent to maintain its activity. Specifically, the stirring assembly 11 includes a second motor 111, which is fixed at the top center of the sealing cap 10, and a stirring paddle 112 is fixed at the bottom end of the output shaft of the second motor 111.

[0030] During the spraying process, the second motor 111 drives the stirring paddle 112 to rotate continuously, stirring the passivating agent inside the storage tank 3. This keeps the passivating agent active, prevents precipitation and clumping, and avoids blockage of the suction pump 71 and nozzle 6 by lumpy passivating agent, which would affect the spraying operation.

[0031] Furthermore, a filter screen 13 is fixedly installed inside the liquid inlet pipe 72. The liquid inlet pipe 72 is located on one side of the agitator 112. Before the passivating agent is sucked into the suction pump 71, the filter screen 13 can block some large particles in the storage tank 3, thereby improving the operational stability of the suction pump 71 and the nozzle 6.

[0032] A feeding hopper 14 extends through one side of the top of the sealing cover 10. The feeding hopper 14 is connected to the inside of the storage tank 3. A threaded cover 15 is threadedly connected to the top of the feeding hopper 14. The feeding hopper 14 is provided to facilitate feeding during operation. After feeding is completed, the threaded cover 15 is closed again to prevent the passivating agent inside the storage tank 3 from being contaminated.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
