Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil remediation technology, and more specifically, to a spraying device for remediating heavy metals in soil. Background Technology
[0002] In the remediation of heavy metals in soil, spraying pesticides is one of the commonly used methods.
[0003] Traditional pesticide application methods often have numerous drawbacks. A common problem is that the applied pesticides fail to penetrate deep into the soil. For example, simple manual application merely spreads the pesticide on the soil surface, relying solely on natural seepage. This results in uneven and incomplete distribution within the soil, preventing deep-seated heavy metals from fully contacting and reacting with the pesticide. While some commercially available mechanical pesticide application devices offer a degree of automation, they suffer from limitations. The pesticide is simply sprinkled onto the surface, making it susceptible to washout by rainwater. Furthermore, their effectiveness in treating deep-seated heavy metal pollution is negligible, leading to an overall ineffective application process. This fails to effectively address soil heavy metal pollution and hinders the efficient implementation of soil heavy metal remediation efforts.
[0004] Therefore, there is an urgent need for a spraying device for heavy metal remediation in soil to improve the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to provide a soil heavy metal remediation spraying device. Driven by a motor, the device rotates the plowing wheel via a transmission assembly, throwing up the soil. After the soil is thrown up by the tilling mechanism, the spraying mechanism operates. The centrifugal wheel in the spraying mechanism then evenly distributes the pesticide under gear transmission, achieving simultaneous tilling and spraying, greatly improving work efficiency and solving the problems mentioned in the background art, namely:
[0006] When pesticides are applied, they are difficult to penetrate deep into the soil. They are only spread on the soil surface and rely solely on natural penetration. This makes it difficult for the pesticides to be evenly and deeply distributed in the soil, resulting in heavy metals deep in the soil not being able to fully contact and react with the pesticides.
[0007] To achieve the above objectives, this utility model provides a spraying device for heavy metal remediation of soil, including a chassis, with a front axle and a rear axle rotatably connected to the front and rear ends of the chassis, and wheels fixedly connected to both ends of the front and rear axles. One end of the chassis is provided with a spraying component, and the other end is provided with a soil turning component.
[0008] The tilling assembly includes a motor, the output shaft of which is fixedly connected to a transmission assembly, and the other end of the transmission assembly is fixedly connected to a plowing wheel, which is used to turn over the soil.
[0009] The spraying component and the tilling component are connected by a linkage group. The linkage group is used to drive the front axle and the rear axle to rotate when the wheel rotates, thereby driving the spraying component to spray pesticides and the tilling component to till the soil.
[0010] In the above technical solution, when the spraying device is working, the rotation of the wheels drives the connected front and rear axles to rotate. On the one hand, this provides the device with the power to move on the soil; on the other hand, this rotation is transmitted through the linkage group, causing the tilling component and the spraying component to operate. In the tilling component, the motor output shaft drives the transmission group one, which in turn drives the plow wheel to rotate and turn over the soil. The spraying component, under the action of the linkage group, uses the power of the wheel rotation to spray pesticides, ultimately achieving simultaneous tilling and spraying operations, improving the efficiency of soil heavy metal remediation.
[0011] Based on this, a second transmission group is connected to the end of the plowing wheel furthest from the first transmission group. The other end of the second transmission group is fixedly connected to the rear axle via its pulley. When the plowing wheel rotates, it transmits power to the second transmission group, thereby driving the rear axle to rotate. Wheels are connected to both ends of the rear axle, and their rotation drives the wheels to roll, moving the device on the soil.
[0012] In another technical solution, a paddle is rotatably connected inside the medicine chamber, the paddle's rotating shaft passes through the lower surface of the medicine chamber, and a gear is fixedly connected to one end of the paddle's rotating shaft located outside the medicine chamber;
[0013] The spraying assembly includes a medicine chamber, which is fixedly connected to the chassis, and the lower surface of the medicine chamber is provided with a plurality of medicine discharge holes for discharging medicine.
[0014] The paddle shaft is fixedly connected to a centrifugal wheel between the second gear and the medicine chamber. The centrifugal wheel is located directly below the medicine chamber and is used to evenly sprinkle the medicine from the medicine chamber along the medicine drop hole.
[0015] In this technical solution, the pesticide container is fixed to the chassis, and its lower surface has several pesticide dispensing holes. When the power source drives the gear two to rotate, the paddle rotates accordingly, dispensing the pesticide from the container through the dispensing holes. At the same time, the centrifugal wheel rotates at high speed, using centrifugal force to evenly distribute the pesticide, ensuring that the pesticide can evenly cover the soil and improve the effect of heavy metal remediation.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This soil heavy metal remediation spraying device, driven by a motor, rotates the plowing wheel through a transmission assembly, throwing the soil up. After the soil is thrown up by the tilling mechanism, the spraying mechanism works, and the centrifugal wheel in the spraying mechanism evenly spreads the pesticide under gear transmission, realizing simultaneous tilling and spraying, which greatly improves work efficiency and saves manpower and time costs; it also allows the pesticide to fall with the thrown soil and penetrate deep into the soil, avoiding the problem of the pesticide only staying on the soil surface.

[0026] 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.
[0027] Currently, pesticides applied during application often fail to penetrate deep into the soil, merely spreading on the surface. Relying solely on natural seepage, they are not evenly and deeply distributed within the soil. This prevents heavy metals deep within the soil from fully contacting and reacting with the pesticide. Please refer to [link / reference needed]. Figures 1-4 As shown, this embodiment provides a soil heavy metal remediation spraying device, including a chassis 100 and a plowing wheel 302. The plowing wheel 302 is rotatably connected to the chassis 100. Specifically, the plowing wheel 302 rotates under the drive of the motor 300. The high-speed rotation of the plowing wheel 302 turns up the soil and then sprays the pesticide.
[0028] During implementation, after the motor 300 starts, its output shaft begins to rotate, and the transmission assembly 301, which is fixedly connected to the output shaft, also starts to operate. The transmission assembly 301, acting as the power transmission medium, transmits the power of the motor 300 to the plowing wheel 302, causing the plowing wheel 302 to rotate at high speed. The rotating plowing wheel 302 cuts into the soil, and thanks to its special structural design and the force generated by its high-speed rotation, it powerfully turns over the soil, creating conditions for subsequent pesticide application.
[0029] See Figure 1 As shown, the chassis 100 serves as the basic load-bearing structure. Its lower front axle 102 and rear axle 103 are rotatably connected at both ends, and the wheels 101 fixed at both ends of the axles constitute a moving system. External power drives the wheels 101 to rotate, and the wheels 101 drive the front axle 102 and rear axle 103 to rotate synchronously, thus propelling the chassis 100 to move in the area of soil to be treated.
[0030] See Figure 3 As shown, as the centrifugal wheel 202 rotates, the support rod drives the paddle 204 to rotate within the medicine chamber 203. During rotation, the paddle 204 continuously pushes the medicine within the medicine chamber 203 toward the through hole on the lower surface of the medicine chamber 203.
[0031] Additionally, see Figure 3 As shown, after the pesticide is directed to the discharge hole 206, it falls from the hole. At this time, the high-speed rotating centrifugal wheel 202 below uses centrifugal force to evenly spread the falling pesticide in all directions, completing the pesticide application operation and thus evenly and regularly distributing the pesticide for treating heavy metals in the soil to the surrounding soil.
[0032] In this embodiment, a soil heavy metal remediation spraying device is used by first connecting the front axle 102 and rear axle 103 at the bottom of the chassis 100 to the wheels 101, forming a mobile base. Then, the pesticide is poured into the pesticide bin 203. When the device is running, the wheels 101 rotate, driving the front axle 102 and rear axle 103 to rotate, propelling the chassis 100 forward. At this time, the tilling assembly 3 begins to work. The output shaft of the motor 300 drives the transmission group one 301 to rotate, which in turn causes the plow wheel 302 to rotate at high speed, powerfully turning over the soil. Simultaneously, the end of the plow wheel 302 away from the transmission group one 301 is connected to the rear axle 103 through the transmission group two 303. When the plow wheel 302 rotates, it drives the rear axle 103 to rotate via the transmission group two 303, further assisting the device's movement and ensuring continuous tilling operations.
[0033] Regarding the spraying component 2, the pesticide container 203 is fixed to the chassis 100, and a pesticide discharge hole 206 is located below the container 203. The rotation of the front axle 102 drives the fixed gear 200 to rotate. Gear 200 meshes with gear 201, causing gear 201 to rotate. This causes the rotating shaft of the paddle 204 and the connected paddle 204 to rotate within the pesticide container 203, distributing the pesticide towards the discharge hole 206. Simultaneously, the centrifugal wheel 202 on the paddle 204's rotating shaft rotates at high speed below the pesticide container 203, evenly distributing the pesticide falling from the discharge hole 206. After tilling and spraying are completed, the leveling plate 205, rotatably connected to one end of the chassis 100, levels the tilled and sprayed soil, ensuring the integrity of the soil heavy metal remediation process and improving remediation effectiveness and efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
