Description

Technical Field

[0001] This invention belongs to the field of farmland heavy metal pollution technology, specifically, it relates to a farmland non-point source and heavy metal pollution control system. Background Technology

[0002] Non-point source pollution and heavy metal pollution in farmland mainly originate from pollution caused by planting methods and pesticide and fertilizer residues. Moreover, due to the significant differences in the quality of pesticides and fertilizers in my country, the phenomenon of farmers' indiscriminate use of pesticides further exacerbates the pollution of land and the environment. To address this, technicians have introduced a farmland non-point source and heavy metal pollution control system, which is mainly used for spraying farmland conditioning solutions and monitoring environmental spaces to conduct real-time monitoring of farmland so that technicians can take corresponding control measures for farmland non-point source and heavy metal pollution.

[0003] However, most existing methods for controlling non-point source metal pollution in farmland involve collecting soil samples from farmland, extracting the metals contained in the soil, and classifying them to determine the impact of the metals on the soil for subsequent treatment. However, the sampling and experimental separation process often requires a long waiting time, which means that when the pollution is close to severe, it cannot be detected in time, leading to the abandonment of large areas of farmland.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0037] Example 1:

[0038] like Figures 1 to 10 As shown, a system for controlling non-point source and heavy metal pollution in farmland includes an installation unit 100, a transmission unit 200, and a striking unit 300. The installation unit 100 includes a trolley base 101 with a rectangular slot 1014 in the middle. Universal wheels 1011 are provided around the bottom of the trolley base 101. A protective shell 1012 is installed above the trolley base 101. An inner protective shell 102 is provided inside the protective shell 1012. A placement slot 1021 is provided on one side wall of the inner protective shell 102. A treatment box 105 is also installed inside the protective shell 1012. A feed inlet 1051 is provided on one side wall of the treatment box 105. A liquid inlet pipe 1013 passes through the treatment box 105 and the protective shell 1012. An arc-shaped mounting plate 104 is fixedly installed inside the protective shell 102, and an installation slot 1041 is provided on the arc-shaped mounting plate 104; the striking unit 300 includes an inclined plate 301, which is installed between the installation slot 1041 and the feed slot 1051. An installation cylinder 302 is provided at the bottom of the inclined plate 301. A limit slot 1042 is provided between the installation cylinder 302 and the arc-shaped mounting plate 104. A sliding slot 3024 is provided above the installation cylinder 302, and an impact rod 3034 is movably passed through the sliding slot 3024; the transmission unit 200 includes a drive assembly and a shovel body 2022. The drive assembly is used to drive the shovel body 2022 to rotate, and the drive assembly can also be used to drive the liquid inlet pipe 1013 to open. The drive assembly controls the shovel body 2022 to remove soil from farmland non-point source pollution, allowing the removed soil to enter the treatment box 105. Simultaneously, because the drive assembly can also rotate the stirring rod 2041, the incoming soil and extract can be mixed, accelerating the separation of metals contained in the soil, which facilitates subsequent detection of the degree of metal pollution in the soil.

[0039] like Figures 3 to 4As shown, in a specific embodiment, the drive assembly includes a dual-axis motor 201, which is mounted on the trolley base 101. A first rotating rod 2011 and a second rotating rod 202 are fixedly mounted at both ends of the dual-axis motor 201. A pulley 2012 is fixedly connected to one end of the first rotating rod 2011 away from the dual-axis motor 201. A belt 2013 is provided on the pulley 2012, and a pulley is also provided at the other end of the belt 2013. A rotating rod 204 is fixedly mounted on the pulley. The rotating rod 204 rotates through the processing box 105. A plurality of symmetrical stirring rods 2041 are fixedly mounted on the rotating rod 204. In this configuration, when the first rotating rod 2011 rotates, it can drive the rotating rod 204 to rotate through the pulley 2012 and belt 2013. When the rotating rod 204 rotates, it can drive the stirring rod 2041 to rotate. When the stirring rod 2041 rotates, it can mix the farmland non-source soil and the extraction liquid entering the treatment box 105, so that the metal pollutants in the farmland non-source soil can be treated.

[0040] like Figures 3 to 6 As shown, furthermore, a connecting rod 2021 is fixedly installed on the second rotating rod 202. A shovel body 2022 is fixedly connected to one side wall of the bottom of the connecting rod 2021. A guide plate 2023 is also fixedly installed on the connecting rod 2021, and a material guide plate 2024 is also provided on the connecting rod 2021. This configuration ensures that when the second rotating rod 202 rotates, it can drive the shovel body 2022, the guide plate 2023, and the material guide plate 2024 on the connecting rod 2021 to rotate.

[0041] like Figure 7 As shown, a first sliding mechanism is further provided between the connecting rod 2021 and the guide plate 2024. The first sliding mechanism includes a first slide groove 2025, which is formed on the connecting rod 2021. A first slider 2026 is slidably installed in the inner cavity of the first slide groove 2025. The upper end of the first slider 2026 away from the first slide groove 2025 is fixedly connected to the guide plate 2024. A first return spring 2027 is fixedly connected above the first slider 2026, and the upper end of the first return spring 2027 away from the first slider 2026 is fixedly connected to the upper part of the inner cavity of the first slide groove 2025. In this configuration, it is ensured that the guide plate 2024 can move downwards when subjected to gravity, allowing it to move up and down, thus enabling faster material feeding.

[0042] Example 2:

[0043] The difference between Embodiment 1 and this embodiment is that: Figure 4 and Figures 8 to 9As shown, a system for controlling non-point source and heavy metal pollution in farmland includes a wedge-shaped block 3021 inside the mounting cylinder 302. The wedge-shaped block 3021 movably passes through a limiting slot 1042. Slide rails 3022 are provided on opposite side walls of the wedge-shaped block 3021. A second return spring 3023 is fixedly connected to the side wall of the wedge-shaped block 3021 away from the second rotating rod 202, and the other end of the second return spring 3023 is fixedly connected to the inner wall of the mounting cylinder 302. This configuration ensures that when the guide plate 2024 continues to rotate, because it is in a sealed fit with the arc-shaped mounting plate 104, the guide plate 2024 can compress the wedge-shaped block 3021, allowing it to move horizontally with the assistance of the slide rails 3022.

[0044] like Figures 8 to 9 As shown in the specific embodiment, the inner walls of the mounting cylinder 302 are provided with irregularly shaped grooves 303 on opposite sides. The two irregularly shaped grooves 303 are symmetrical to each other. Guide sliders 3031 are slidably installed in the inner cavities of the two irregularly shaped grooves 303. The two guide sliders 3031 are symmetrical to each other. A fixing plate 3032 is fixedly connected to the opposite side wall of the two guide sliders 3031. A telescopic rod 3033 is fixedly connected to the bottom of the fixing plate 3032. The other end of the telescopic rod 3033 is fixedly connected to the wedge-shaped block 3021. An impact rod 3034 is fixedly connected to the top of the fixing plate 3032. In this configuration, when the wedge block 3021 moves horizontally, it will drive the telescopic rod 3033 to move horizontally. When the telescopic rod 3033 moves horizontally, it will pull the fixed plate 3032 to move horizontally with the assistance of the irregular groove 303 and the guide slider 3031. This will drive the fixed plate 3032 to move up and down. When the fixed plate 3032 moves up and down, it will drive the impact rod 3034 to impact the inclined plate 301, so that the farmland non-soil that has not slid down on the inclined plate 301 can continue to slide down.

[0045] Example 3:

[0046] The difference between Embodiment 2 and this embodiment is that: Figures 2 to 4 and Figure 10As shown, a farmland non-point source and heavy metal pollution control system includes a second sliding mechanism located above the inner cavity of a treatment tank 105. The second sliding mechanism includes two movable sliding grooves 1062, which are respectively located above the inner cavity of the treatment tank 105 and are symmetrical to each other. A movable slider 1063 is slidably installed in the inner cavity of each of the two movable sliding grooves 1062. The two movable sliders 1063 are symmetrical to each other, and a sealing plate 106 is fixedly connected to the bottom of each of the two movable sliders 1063. A drive plate 1061 is fixedly connected to the bottom of the sealing plate 106, and the drive plate 1061 and the stirring rod 2041 are mutually engaged. In this configuration, the rotating rod 204 is designed to rotate, which in turn drives the stirring rod 2041 to rotate. The rotation of the stirring rod 2041 pushes the drive plate 1061 located above, allowing the drive plate 1061 to move the sealing plate 106 horizontally with the assistance of the moving slide 1062 and the moving slider 1063, thereby opening the liquid inlet pipe 1013.

[0047] like Figure 10 As shown, in a specific embodiment, one end of each of the two movable sliders 1063 is fixedly connected to a third return spring 1064, and the ends of the two third return springs 1064 away from the movable sliders 1063 are fixedly connected to the inner wall of the movable groove 1062. This configuration ensures that when the stirring rod 2041 leaves the drive plate 1061, it can be reset with the assistance of the third return springs 1064.

[0048] like Figures 3 to 4 As shown, furthermore, slots are provided at the treatment box 105 and the trolley base 101, and two symmetrically arranged electrically controlled sealing flip plates 2042 are installed inside the slots. In this configuration, the operator can control the electrically controlled sealing flip plates 2042 to open via a controller, enabling the treatment of soil and metal pollutants.

[0049] The implementation principle of the farmland non-point source and heavy metal pollution control system of the present invention is as follows:

[0050] First, the staff moved the trolley base 101 to the location in the farmland where the non-point source pollution needed to be detected. When the movement was completed, the staff controlled the dual-axis motor 201 to run, and at the same time, the staff added extraction liquid into the liquid inlet pipe 1013.

[0051] When the dual-axis motor 201 is running, it drives the second rotating rod 202 to rotate. When the second rotating rod 202 rotates, it drives the connecting rod 2021 to rotate. When the connecting rod 2021 rotates, it drives the shovel body 2022 to remove the soil from the farmland surface, allowing the farmland surface soil to enter the inner cavity of the shovel body 2022. Because the shovel body 2022 can rotate, when the shovel body 2022 rotates 90 degrees clockwise from a perpendicular position to the ground, it continues to rotate so that the shovel body 2022 is in an upward angled position. Therefore, the soil in the shovel body 2022 can fall onto the guide plate 2023 and then into the guide plate 2024, thereby collecting the farmland surface soil through the guide plate 2024.

[0052] When collecting non-point source soil from farmland, the soil is still rotating. After rotating 180 degrees, it continues to rotate, allowing the guide plate 2024 to be tilted downwards. However, because the guide plate 2024 and the arc-shaped mounting plate 104 are in a sealed fit, the soil placed inside the guide plate 2024 will fall from the mounting slot 1041 at the arc-shaped mounting plate 104 into the inner cavity of the treatment box 105 from the installation slot 1041.

[0053] Meanwhile, the second rotating rod 202 continues to rotate, thus allowing the guide plate 2024 to continue rotating. When the guide plate 2024 continues to rotate, because it is sealed and fitted with the arc-shaped mounting plate 104, the guide plate 2024 can squeeze the wedge block 3021 to move horizontally with the assistance of the slide rail 3022. When the wedge block 3021 moves horizontally, it can drive the telescopic rod 3033 to move horizontally. When the telescopic rod 3033 moves horizontally, it can pull the fixed plate 3032 to move horizontally with the assistance of the irregular slide groove 303 and the guide slider 3031, thereby driving the fixed plate 3032 to move up and down. When the fixed plate 3032 moves up and down, it can drive the impact rod 3034 to impact the inclined plate 301, so that the farmland non-soil that has not slid off the inclined plate 301 can continue to slide off.

[0054] Simultaneously, when the first rotating rod 2011 rotates, it can drive the rotating rod 204 to rotate through the pulley 2012 and belt 2013. When the rotating rod 204 rotates, it can drive the stirring rod 2041 to rotate. Therefore, the rotation of the stirring rod 2041 can push the drive plate 1061 set above, so that the drive plate 1061 can drive the sealing plate 106 to move horizontally with the assistance of the moving slide 1062 and the moving slider 1063, thereby opening the liquid inlet pipe 1013. When the stirring rod 2041 leaves the drive plate 1061, it can be reset with the assistance of the third return spring 1064. When the stirring rod 2041 rotates, it can mix the farmland non-source soil and the extraction liquid entering the treatment tank 105, so that the metal pollutants in the farmland non-source soil can be treated.

[0055] Subsequently, staff can use a controller to open the electrically controlled sealing flip plate 2042, which allows for the treatment of soil and metal pollutants.
