Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically relating to a heavy metal monitoring device for farmland soil. Background Technology

[0002] In the fields of environmental monitoring and farmland soil monitoring, soil heavy metal monitoring devices are needed. Existing soil heavy metal monitoring devices use handheld soil metal mass spectrometers. However, in actual use, when the soil metal mass spectrometer is pointed at the soil to complete the monitoring, it will be unable to detect soil at different depths. Therefore, this utility model proposes a farmland soil heavy metal monitoring device. Utility Model Content

[0003] The purpose of this invention is to provide a heavy metal monitoring device for farmland soil that can monitor soil at different depths.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A heavy metal monitoring device for farmland soil includes a handheld soil metal mass spectrometer and an auxiliary device. The auxiliary device includes a frame, a drive mechanism on the frame, and an expansion component on the drive mechanism. The drive mechanism is used to drive the expansion component to open and expand the soil.

[0006] Preferably, the frame body has an overall frame structure, and the bottom support legs of the frame body have a tapered structure.

[0007] Preferably, the driving mechanism includes an electric telescopic rod disposed on the frame, the electric telescopic rod is placed vertically, the lower end of the electric telescopic rod is provided with a driving frame, and a U-shaped slider is movably sleeved on the driving frame.

[0008] Preferably, the frame body is provided with symmetrical slide rails on its side, and a strip slider is movably provided inside the slide rail, with the end of the strip slider connected to the side of the drive frame.

[0009] Preferably, the expansion assembly includes an opening and closing plate disposed at the lower end of the U-shaped slider, the two opening and closing plates are symmetrical to each other, one side of the opening and closing plate is provided with a reinforcing rib, the other side of the opening and closing plate is provided with an array of protrusions, the lower end of the opening and closing plate is blade-shaped, and the lower end of the reinforcing rib is blade-shaped.

[0010] Preferably, the drive mechanism further includes a gear rod disposed on the upper end of the reinforcing rib and a drive motor disposed in the middle of the drive frame, wherein a drive gear is provided at the lower output end of the drive motor, and the drive gear meshes with the gear rod.

[0011] The technical effects achieved by this utility model are as follows:

[0012] In this invention, the frame is placed above the monitored soil plane. The tapered structure at the bottom of the frame's legs facilitates fixation. An electric telescopic rod drives the drive frame vertically downwards, which in turn drives two opening and closing plates vertically downwards. During this downward movement, the strip-shaped slider slides laterally within the slide rail, enhancing the stability of the drive frame and consequently the vertical downward movement of the two opening and closing plates. The blade-shaped design of the opening and closing plates and the lower ends of the reinforcing ribs facilitates entry into the soil. The reinforcing ribs ensure the strength of the opening and closing plates, allowing them to expand outwards smoothly. The drive motor is a geared motor that drives the drive gear to rotate. The drive gear meshes with two gear rods, causing them to slide laterally, which in turn drives the opening and closing plates to slide laterally. Simultaneously, the loop-shaped slider slides laterally on the drive frame, maintaining the stability of the opening and closing plates. The mechanism controls the rotation direction of the drive motor output, causing the two opening plates to simultaneously move towards the center or simultaneously open to both ends. Because the opening plates and the lower ends of the reinforcing ribs are blade-shaped, the opening plates can more easily enter the soil. The reinforcing ribs ensure the strength of the opening plates, allowing them to expand smoothly outwards. This not only allows the opening plates to expand outwards, creating a deep soil trench, but also allows the already opened opening plates to be inserted into the soil and then the soil to be extracted. The array of protrusions on the other side of the opening plates facilitates easy soil extraction. This invention also enables deep soil sampling, followed by heavy metal monitoring of the soil at the bottom of the trench using a handheld soil metal mass spectrometer. Furthermore, it can create soil trenches of different depths as needed, ultimately enabling heavy metal monitoring of the soil at different depths using a soil metal mass spectrometer.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figures 1-4 As shown, a heavy metal monitoring device for farmland soil includes a handheld soil metal mass spectrometer and an auxiliary device. The auxiliary device includes a frame 1, a drive mechanism 2 on the frame 1, and an expansion component 3 on the drive mechanism 2. The drive mechanism 2 is used to drive the expansion component 3 to open and expand the soil.

[0021] like Figures 1-4 As shown, in this utility model, the driving mechanism 2 can drive the expansion component 3 into the soil and simultaneously drive the expansion component 3 to expand outward, thereby creating a deep trench in the flat farmland soil. Then, a handheld soil metal mass spectrometer is used to monitor the heavy metals in the soil at the bottom of the deep trench. At the same time, soil trenches of different depths can be created according to actual needs, and finally, soil heavy metal monitoring can be completed in conjunction with the soil metal mass spectrometer, enabling monitoring of soil at different depths.

[0022] Preferably, the frame 1 is an integral frame structure, and the bottom legs of the frame 1 have a tapered structure.

[0023] In actual use, the frame 1 is placed above the plane of the soil being monitored. Since the bottom legs of the frame 1 have a tapered structure, it is easier to fix the frame 1.

[0024] Preferably, the drive mechanism 2 includes an electric telescopic rod 201 mounted on the frame 1. The electric telescopic rod 201 is placed vertically, and a drive frame 202 is provided at the lower end of the electric telescopic rod 201. A U-shaped slider 203 is movably mounted on the drive frame 202.

[0025] In actual use, the electric telescopic rod 201 drives the drive frame 202 vertically downward, and the drive frame 202 drives the two opening and closing plates 301 vertically downward.

[0026] Preferably, the frame 1 is provided with symmetrical slide rails 204 on the side, and a strip slider 205 is movably provided inside the slide rail 204. The end of the strip slider 205 is connected to the side of the drive frame 202.

[0027] like Figures 1-4 As shown, in actual use, when the opening and closing plate 301 is vertically downward, the strip slider 205 slides laterally inside the slide rail 204, making the drive frame 202 more stable during the lateral sliding process, and thus making the two opening and closing plates 301 more stable when vertically downward.

[0028] Preferably, the expansion component 3 includes an opening and closing plate 301 disposed at the lower end of the loop slider 203. The two opening and closing plates 301 are symmetrical to each other. One side of the opening and closing plate 301 is provided with a reinforcing rib 302, and the other side of the opening and closing plate 301 is provided with an array of protrusions. The lower end of the opening and closing plate 301 is blade-shaped, and the lower end of the reinforcing rib 302 is blade-shaped.

[0029] like Figures 1-4 As shown, in actual use, the lower ends of the opening and closing plate 301 and the reinforcing rib 302 are blade-shaped, making it easier for the opening and closing plate 301 to enter the soil. By setting the reinforcing rib 302, the strength of the opening and closing plate 301 is guaranteed, allowing the opening and closing plate 301 to expand outward smoothly.

[0030] like Figures 1-4 As shown, in this utility model, not only can the opening and closing plate 301 expand outward to open a deep soil trench, but the already opened opening and closing plate 301 can also be inserted into the soil and then the soil can be clamped out. Since the other side of the opening and closing plate 301 is provided with arrayed protrusions, the soil can be easily clamped out, so that this utility model can also perform deep soil sampling.

[0031] Preferably, the drive mechanism 2 further includes a gear rod 206 disposed on the upper end of the reinforcing rib 302 and a drive motor 207 disposed in the middle of the drive frame 202. The lower output end of the drive motor 207 is provided with a drive gear 208, and the drive gear 208 meshes with the gear rod 206.

[0032] like Figures 1-4 As shown, in this utility model, the drive motor 207 is a geared motor. The drive motor 207 drives the drive gear 208 to rotate. The drive gear 208 meshes with the two gear rods 206, causing the two gear rods 206 to slide laterally, which in turn drives the opening and closing plate 301 to slide laterally. At this time, the loop slider 203 slides laterally on the drive frame 202 to maintain the stable sliding of the opening and closing plate 301. Finally, by controlling the rotation direction of the output end of the drive motor 207, the two opening and closing plates 301 can be driven to move towards the center at the same time or spread out to both ends at the same time.

[0033] like Figures 1-4As shown, the working principle of this utility model is as follows: The frame 1 is placed above the plane of the soil to be monitored. Because the bottom legs of the frame 1 have a tapered structure, it is easier to fix the frame 1. The electric telescopic rod 201 drives the drive frame 202 vertically downwards. The drive frame 202 drives the two opening and closing plates 301 vertically downwards. During the vertical downward movement of the opening and closing plates 301, the strip slider 205 slides laterally inside the slide rail 204, making the lateral sliding of the drive frame 202 more stable, thus making the vertical downward movement of the two opening and closing plates 301 more stable. To enhance stability, the blade-shaped lower ends of the opening and closing plate 301 and the reinforcing rib 302 facilitate the entry of the opening and closing plate 301 into the soil. The reinforcing rib 302 ensures the strength of the opening and closing plate 301, allowing it to expand smoothly outwards. The drive motor 207 is a geared motor that drives the drive gear 208 to rotate. The drive gear 208 meshes with the two gear rods 206, causing the two gear rods 206 to slide laterally, which in turn drives the opening and closing plate 301 to slide laterally. At this time, the loop-shaped slider 20... 3. The sliding mechanism on the drive frame 202 ensures stable sliding of the opening and closing plate 301. Ultimately, by controlling the rotation direction of the drive motor 207's output, the two opening and closing plates 301 are simultaneously moved towards the center or simultaneously spread outwards. Because the lower ends of the opening and closing plates 301 and the reinforcing ribs 302 are blade-shaped, the opening and closing plates 301 can more easily enter the soil. The reinforcing ribs 302 ensure the strength of the opening and closing plates 301, allowing them to expand smoothly outwards. This not only allows the opening and closing plates 301 to expand outwards... The device allows for the creation of a deep soil trench. The opened hinge plate 301 can be inserted into the soil, and the soil can be easily extracted. Because the other side of the hinge plate 301 has an array of protrusions, the soil can be easily extracted. This invention also enables deep soil sampling. A handheld soil metal mass spectrometer is then used to monitor heavy metals in the soil at the bottom of the trench. Furthermore, soil trenches of different depths can be created according to actual needs, ultimately enabling soil heavy metal monitoring at different depths using a soil metal mass spectrometer.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
