Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, and in particular to a soil sampling device for environmental monitoring. Background Technology

[0002] Soil sampling devices are specialized tools used to collect soil samples. Some devices are equipped with scale markings to control the sampling depth. Manual or motorized drive methods can improve sampling efficiency. They are widely used in soil monitoring, agricultural research, environmental surveys and other fields to provide basic samples for analyzing soil physicochemical properties, nutrient status and pollution.

[0003] Chinese patent CN221528041U discloses a soil sampling device for environmental monitoring, including a sleeve. A sampling head is located at the bottom of the sleeve, and an opening is located at the bottom of the sampling head. A receiving mechanism is located at the top of the sleeve, comprising a receiving tube, a second threaded groove, a second threaded head, and a sealing head. This invention utilizes a combination of a pressure rod, a spring, a push rod, a sampling head, a sleeve, and a handle. During operation, the user holds both handles and presses down to insert the sampling head into a designated location on the ground to collect a soil sample. After collection, the sampling head is removed from the ground, and the handles are released. The stretched spring then presses down the pressure rod, which in turn controls the push rod to extend into the sampling head, quickly pushing the soil inside the sampling head out of the opening, thus facilitating rapid unloading.

[0004] Existing technologies often have the following drawbacks: In the actual use of soil sampling devices, the sampling tube is often directly inserted into the ground. When the sampling tube is inserted into the ground at an angle, the angle will cause the soil profile layers intercepted by the sampling tube to be inconsistent with the actual vertical profile. This may result in the omission or over-sampling of a certain layer of soil, making the collected samples unable to truly reflect the soil structure, nutrient distribution or pollution status of the sampling point, thus affecting the accuracy of subsequent analysis results.

[0005] Therefore, this utility model provides a soil sampling device for environmental monitoring. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where sampling is prone to tilting, and to propose a soil sampling device for environmental monitoring.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a soil sampling device for environmental monitoring, comprising a sampling rod, one end of which is fixedly connected to a sampling cylinder, and the other end of which is fixedly connected to two handles. The side wall of the sampling rod is provided with a limiting structure, which includes a positioning ring fitted around the outside of the sampling rod. Three support plates are fixedly connected to the side wall of the positioning ring. Two limiting strips are fixedly connected to the ends of the three support plates that are far apart from each other. Sliding plates are slidably connected to the side walls of the two limiting strips. A support rod is fixedly connected to the lower end of the sliding plate. A support plate is fixedly connected to the lower end of the support rod. Two rectangular blocks are fixedly connected to the upper surface of the positioning ring. Two positioning strips are slidably connected inside the rectangular blocks. A positioning block is fixedly connected to the end of each positioning strip near the sampling rod. A V-groove is formed on the side of the positioning block near the sampling rod. A drive rod is threadedly connected inside the rectangular plate, and the drive rod and the positioning block are rotatably connected.

[0008] The effect achieved by the above components is as follows: by setting a limiting structure, the sampling rod is positioned between two positioning blocks. The two positioning blocks can guide the sampling rod when it is sampling, thereby avoiding the phenomenon of tilting during the movement of the sampling rod and improving the accuracy of the sampling results.

[0009] Preferably, the positioning block has two rollers rotatably connected inside a V-groove.

[0010] The effect achieved by the above components is that the roller in the V-groove contacts the sampling rod, thereby limiting and guiding the sampling rod.

[0011] Preferably, a plurality of tapered rods are fixedly connected to the lower surface of the support plate.

[0012] The effect achieved by the above components is to enhance the overall stability of the device by inserting the cone rod below the support plate into the soil.

[0013] Preferably, the slide plate is internally threaded with a screw, and the screw is internally rotatably connected to the support plate.

[0014] The effect achieved by the above components is as follows: by fixing with screws and adjusting the position of the support rod, the second support plate below the support rod is moved to a relatively flat position on the ground.

[0015] Preferably, the lower side of the support rod is provided with an auxiliary structure, the auxiliary structure including a second mounting strip fixedly connected to the lower side of the support rod, a sliding pin being slidably connected inside the second mounting strip, and a support ring being fixedly connected to the lower end of the sliding pin.

[0016] The effect achieved by the above components is as follows: by setting up the auxiliary structure, it is convenient to extend the support ring flexibly. When the device is not in use, the support ring can be moved to the position of the tip of the cone rod, which can avoid the phenomenon that the tip of the cone rod can easily damage other items when the device is not in use and is stored, thus improving the safety of carrying the sampling device.

[0017] Preferably, the support ring is located on the outside of several tapered rods.

[0018] The aforementioned components achieve the following effect: they move the support ring to the outside of the cone tip, thus shielding the cone tip and preventing it from damaging other items during carrying or storage, thereby improving safety.

[0019] Preferably, a first mounting strip is fixedly connected to the side wall of the support rod, and a screw pin is threadedly connected to the inside of the first mounting strip, and the screw pin is rotatably connected to the inside of the support ring.

[0020] The effect achieved by the above components is: rotating the screw pin causes the support ring to slide along the second mounting strip.

[0021] In summary: 1. In this utility model, by setting a limiting structure, the sampling rod is positioned between two positioning blocks. The two positioning blocks can guide the sampling rod when it is sampling, thereby avoiding the phenomenon of tilting during the movement of the sampling rod and improving the accuracy of the sampling results.

[0022] 2. By setting an auxiliary structure, this utility model facilitates the flexible extension of the support ring. When the device is not in use, the support ring can be moved to the position of the tip of the cone rod, which can prevent the tip of the cone rod from easily damaging other items when the device is stored, thus improving the safety of carrying the sampling device.

[0025] Reference Figure 1 As shown, this utility model provides a technical solution: a soil sampling device for environmental monitoring, including a sampling rod 1, a sampling tube 3 fixedly connected to one end of the sampling rod 1, two handles 2 fixedly connected to the other end of the sampling rod 1, a limiting structure 4 provided on the side wall of the sampling rod 1, and an auxiliary structure 5 provided on the lower side of the support rod 402.

[0026] The following section will explain the specific settings and functions of its limiting structure 4 and auxiliary structure 5.

[0027] Reference Figures 1-4As shown in this embodiment: the limiting structure 4 includes a positioning ring 401 sleeved on the outside of the sampling rod 1. Three support plates 413 are fixedly connected to the side wall of the positioning ring 401. Two limiting strips 404 are fixedly connected to the ends of the three support plates 413 that are far apart from each other. A sliding plate 406 is slidably connected to the side wall of the two limiting strips 404. A support rod 402 is fixedly connected to the lower end of the sliding plate 406. A support plate 403 is fixedly connected to the lower end of the support rod 402. Two rectangular blocks 407 are fixedly connected to the upper surface of the positioning ring 401. Two positioning strips 408 are slidably connected inside the rectangular blocks 407. A positioning block 410 is fixedly connected to the end of the two positioning strips 408 near the sampling rod 1. A V-groove is opened on the side of the positioning block 410 near the sampling rod 1. A drive rod 409 is threadedly connected inside the rectangular plate. The drive rod 409 and the positioning block 410 are rotatably connected inside. By setting a limiting structure 4, the sampling rod 1 is positioned between two positioning blocks 410. The two positioning blocks 410 can guide the sampling rod 1 during sampling, thereby avoiding tilting of the sampling rod 1 during movement and improving the accuracy of the sampling results. The positioning block 410 has two rollers 411 internally connected to a V-groove. The rollers 411 in the V-groove contact the sampling rod 1 to limit and guide the sampling rod 1. Several conical rods 412 are fixedly connected to the lower surface of the support plate 403. The conical rods 412 on the lower surface of the support plate 403 are inserted into the soil to enhance the overall stability of the device. The internal thread of the sliding plate 406 is connected to a screw 405, which is internally rotatably connected to the support plate 413. With the screw 405 fixed, the position of the support rod 402 is adjusted to move the support plate 413 below the support rod 402 to a relatively flat position on the ground.

[0028] Reference Figures 1-2 and Figure 5 As shown, specifically, the auxiliary structure 5 includes a second mounting strip 52 fixedly connected to the lower side of the support rod 402. A sliding pin 54 is slidably connected inside the second mounting strip 52, and a support ring 55 is fixedly connected to the lower end of the sliding pin 54. By setting the auxiliary structure 5, the flexible extension of the support ring 55 is facilitated. When the device is not in use, the support ring 55 can be moved to the tip of the cone rod 412, preventing the tip of the cone rod 412 from easily damaging other items when the device is stored, thus improving the safety of carrying the sampling device. The support ring 55 is located outside several cone rods 412. Moving the support ring 55 to the outside of the tip of the cone rod 412 forms a shield for the tip of the cone rod 412, preventing the cone rod 412 from damaging other items during carrying or storage, thus improving safety. A first mounting strip 51 is fixedly connected to the side wall of the support rod 402. A screw pin 53 is threadedly connected inside the first mounting strip 51, and the screw pin 53 is rotatably connected to the support ring 55. Rotate the screw pin 53 to cause the support ring 55 to slide along the second mounting strip 52.

[0029] Working principle: In use, first adjust the position of the sliding plate 406 on the limiting strip 404 and fix it with the screw 405. Adjust the position of the support rod 402 to move the support plate 403 below the support rod 402 to a relatively flat position on the ground, so that the support plate 403 is placed stably on the ground. At the same time, the cone rod 412 on the lower surface of the support plate 403 is inserted into the soil to enhance the overall stability of the device. Then, rotate the drive rod 409 to drive the positioning blocks 410 to move, so that the V-grooves of the two positioning blocks 410 fit against the sampling rod 1, and the rollers 411 in the V-grooves are in contact with the sampling rod 1. The sampling rod 1 is guided by the positioning block 410. The operator holds the handle 2 and presses down or rotates the sampling rod 1. Under the guidance of the positioning block 410, the sampling rod 1 drives the sampling tube 3 to be inserted vertically into the soil, effectively avoiding tilting. After sampling, the sampling rod 1 is pulled out upwards, and the soil sample can be obtained through the sampling tube 3. By setting the limiting structure 4, the sampling rod 1 is positioned between the two positioning blocks 410. The two positioning blocks 410 can guide the sampling rod 1 when sampling, thereby avoiding the phenomenon of tilting of the sampling rod 1 during movement and improving the accuracy of the sampling results.

[0030] When the device is not in use, rotating the screw pin 53 causes the support ring 55 to slide along the second mounting strip 52, moving the support ring 55 to the outside of the tip of the cone rod 412, thus shielding the tip of the cone rod 412 and preventing it from damaging other items during carrying or storage, thereby improving safety. The auxiliary structure 5 facilitates the flexible extension of the support ring 55. Moving the support ring 55 to the tip of the cone rod 412 when the device is not in use prevents the tip of the cone rod 412 from easily damaging other items when the device is stored, thus improving the safety of carrying the sampling device. The verticality of the sampling is ensured by the limiting structure 4 throughout the process, and the safety and convenience of using the device are improved with the help of the auxiliary structure 5.
