Abstract
Description
Technical Field
[0001] This utility model relates to a water and soil conservation runoff sediment sampling device, belonging to the field of sediment sampling technology. Background Technology
[0002] To prevent excessive soil erosion, from the perspective of protecting soil and water resources, it is necessary to improve and maintain land productivity through improvement and rational utilization. In order to fully realize the ecological, economic, and social benefits of soil and water resources, comprehensive protection measures must be adopted. The prevention and control of soil erosion often requires collecting sediment samples for experiments. Data is obtained by sampling sediment, and the calculated data is used to monitor the effectiveness of soil and water conservation and to decide how to implement the next steps in the control measures.
[0003] In the current sediment sampling process, operators use sampling buckets to directly sample the water area. The sampling process relies on the precision of manual operation, and there is no unified standard for the operation, which results in large sampling errors and easily leads to inaccurate experimental data.
[0004] In summary, the existing sediment sampling process lacks a unified standard, resulting in technical problems such as large sampling errors and inaccurate experimental data. Summary of the Invention
[0005] This invention addresses the technical problems of large sampling errors and inaccurate experimental data caused by the lack of standardized operation procedures in existing sediment sampling processes. It provides a soil and water conservation runoff sediment sampling device comprising two sampling buckets, a lifting rod, a limiting mechanism, a lifting rope, a fixed crossbar, a connecting rod, a sleeve rod, a spring, and a telescopic rod. Each sampling bucket has an opening on its side, with the openings of the two buckets facing each other. The tops of the two buckets are hinged together, allowing them to open or close. The top of each bucket is fixedly connected to one end of the lifting rod. A limiting mechanism is installed in the middle of the lifting rod to restrict the relative position of the two sampling buckets. The other end of the lifting rod is connected to the lifting rope, the top of which is connected to the middle of the fixed crossbar. Downward connecting rods are installed at both ends of the fixed crossbar. A sleeve rod is installed at the lower end of the connecting rod, containing a spring. A telescopic rod that can extend and retract vertically is fitted onto the lower end of the sleeve rod. The two ends of the spring are fixedly connected to the sleeve rod and the telescopic rod, respectively.
[0006] As another improvement of this utility model, the limiting mechanism includes a limiting bolt and a limiting rod. A threaded hole is provided in the middle of the lifting rod. Two limiting bolts are respectively installed in the middle of the two lifting rods through the threaded hole. One end of the limiting rod is rotatably fitted onto the rod of one limiting bolt. The other end of the limiting rod is provided with an upward limiting notch. The limiting notch is detachably fitted onto the rod of another limiting bolt.
[0007] As another improvement of this utility model, a handle perpendicular to the direction of the limiting rod is provided in the middle of the limiting rod.
[0008] As another improvement of this utility model, the connecting rod is L-shaped, and a reinforcing rod is connected between the two ends of the L-shaped connecting rod.
[0009] As another improvement of this utility model, it also includes a support plate, which is disc-shaped and is respectively installed at the bottom of the two telescopic rods.
[0010] As another improvement of this utility model, the bottom of the support plate is provided with several contact balls.
[0011] As another improvement of this utility model, it also includes a counterweight block, which is detachably mounted on the outer side of the sampling hopper.
[0012] As another improvement of this utility model, the counterweight is an iron block, which is detachably installed on the outer side of the sampling hopper by magnetic attraction.
[0013] As another improvement of this utility model, a limiting groove is provided in the middle of the crossbar, and the top of the lifting rope is detachably snapped into the limiting groove.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model discloses a soil and water conservation runoff sediment sampling device. The two sampling hoppers are opened or closed by a hinge connection. In conjunction with a lifting rod, a limiting mechanism, a lifting rope, a fixed crossbar, a connecting rod, a sleeve rod, a spring, and a telescopic rod, when collecting sediment samples, the lifting rod is first supported by the limiting mechanism. After moving the device to the sampling location, the crossbar is pressed down vertically. After the telescopic rod is pressed to its shortest stroke, the limiting mechanism automatically unlocks. Then, the crossbar is lifted, the two sampling hoppers close, and the sampling operation is completed. There is no need for the operator to rely on experience to judge the operation. The operation process is simple and stable.
[0016] 2. In the process of sampling and lifting the crossbar, the spring inside the sleeve rod, which is under compression, performs a restoring action, which shortens the time required for the lifting process and is labor-saving and efficient.
[0017] 3. The bottom of the two telescopic rods of the soil and water conservation runoff sediment sampling device of this utility model is equipped with a support plate, which enhances the stability of the device during use. Attached Figure Description

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Specific implementation method one: Combining Figures 1 to 6 This embodiment describes a soil and water conservation runoff sediment sampling device, which includes two sampling buckets 1, a lifting rod 2, a limiting mechanism, a lifting rope 3, a crossbar 4, a connecting rod 5, a sleeve rod 6, a spring 7, and a telescopic rod 8. Each sampling bucket 1 has an opening on its side. The openings of the two sampling buckets 1 are opposite each other, and the tops of the two sampling buckets 1 are hinged together. The two sampling buckets 1 can be opened or closed by the hinged connection. When the two sampling buckets 1 are closed, they form a sealed structure. The tops of the sampling buckets 1 are connected to... One end of the lifting rod 2 is fixedly connected, and a limiting mechanism is installed in the middle of the lifting rod 2. The limiting mechanism is used to limit the relative position of the two sampling buckets 1. The other end of the lifting rod 2 is connected to a lifting rope 3. The top end of the lifting rope 3 is connected to the middle of the crossbar 4. Downward connecting rods 5 are installed at both ends of the crossbar 4. A sleeve rod 6 is installed at the lower end of the connecting rod 5. A spring 7 is installed inside the sleeve rod 6. A telescopic rod 8 that can extend and retract vertically is fitted at the lower end of the sleeve rod 6. The two ends of the spring 7 are fixedly connected to the sleeve rod 6 and the telescopic rod 8, respectively.
[0026] In its limited-position state, the lifting rod 2 is connected to the lifting rope 3 and the sampling bucket 1 to form a lifting mechanism. The crossbar 4, connecting rod 5, sleeve rod 6, spring 7, and telescopic rod 8 are connected to form a spring rod mechanism. The height of the lifting mechanism is between the maximum and minimum vertical stroke height of the spring rod mechanism. When collecting sediment samples, the lifting rod is first supported by the limiting mechanism. Due to the weight of the sampling bucket, both lifting rods are subjected to relative forces along the direction of the limiting mechanism. Combined with the supporting force of the limiting mechanism on the lifting rod, the limiting lock is completed. After the equipment is moved to the sampling location, the crossbar is pressed down vertically. After the telescopic rod is pressed to its shortest stroke, the bottom of the sampling bucket touches the river bottom and is supported. The limiting mechanism automatically unlocks. Then the crossbar is lifted, the two sampling buckets close, and a sealed structure is formed. The sampling operation is completed. There is no need for the operator to rely on experience to judge the operation. The operation process is simple and stable.
[0027] Specific Implementation Method Two: Combining Figures 1 to 6 This embodiment differs from specific embodiment one in that the limiting mechanism includes a limiting bolt 31 and a limiting rod 32. The middle part of the lifting rod 2 is provided with a threaded hole, and the two limiting bolts 31 are respectively installed in the middle parts of the two lifting rods 2 through the threaded holes. One end of the limiting rod 32 is rotatably fitted onto the rod part of one limiting bolt 31, and the other end of the limiting rod 32 is provided with an upward limiting notch 33, which is detachably fitted onto the rod part of another limiting bolt 31. First, the lifting rod is supported by the limiting notch 33 and the limiting bolt 31 on the limiting rod. Due to the weight of the sampling bucket, both lifting rods are subjected to relative component forces along the direction of the limiting rod. Combined with the supporting force of the limiting rod on the lifting rod, the limiting lock is completed. After moving the equipment to the sampling location, the horizontal bar is pressed down vertically. After the telescopic rod is pressed to its shortest stroke, the bottom of the sampling bucket touches the riverbed and receives supporting force. The limiting notch 33 and the limiting bolt 31 on the limiting rod automatically separate. Then, the horizontal bar is lifted, the two sampling buckets close, and the sampling operation is completed. The operation is simple and stable, eliminating the need for operators to rely on experience. Other components and connection methods are the same as in Specific Implementation Method 1.
[0028] Specific implementation method three: Combining Figure 6 This embodiment differs from specific embodiment one in that a handle 34 perpendicular to the direction of the limiting rod 32 is provided in the middle of the limiting rod 32. Its function is to facilitate operation of the limiting rod. Other components and connection methods are the same as in specific embodiment one or two.
[0029] Specific implementation method four: Combination Figures 1 to 6This embodiment differs from specific embodiment one in that the connecting rod 5 is L-shaped, and a reinforcing rod 51 connects the two ends of the L-shaped connecting rod 5. This makes the equipment in this embodiment more stable and more reliable. Other components and connection methods are the same as any one of specific embodiments one to three.
[0030] Specific Implementation Method Five: Combining Figures 1 to 6 This embodiment differs from specific embodiment one in that it further includes a support plate 9, which is disc-shaped and is respectively installed at the bottom of the two telescopic rods 8. This enhances the stability of the equipment during use. Other components and connection methods are the same as any one of specific embodiments one to four.

Their function is to increase friction and enhance the stability of the equipment during use. Other components and connection methods are the same as any one of specific embodiments one through five.
[0032] Specific implementation method seven: Combination Figures 1 to 6 This embodiment differs from specific embodiment one in that it also includes a counterweight 10, which is detachably mounted on the outer surface of the sampling hopper 1. Adding a counterweight allows for adaptation to more usage environments and enhances the practicality of the equipment. Other components and connection methods are the same as in any one of specific embodiments one through six.
[0033] Specific implementation method eight: Combination Figures 1 to 6 This embodiment differs from specific embodiment one in that the counterweight 10 is an iron block, which is detachably mounted on the outer surface of the sampling hopper 1 using a magnetic attraction method. Adding a counterweight allows for adaptation to more usage environments, enhances the practicality of the equipment, and the magnetic attraction method makes it more convenient and faster to remove. Other components and connection methods are the same as any one of specific embodiments one through seven.
[0034] Specific Implementation Method Nine: Combining Figures 1 to 6 This embodiment differs from specific embodiment one in that a limiting groove is provided in the middle of the crossbar 4, and the top end of the lifting rope 3 is detachably snapped into the limiting groove.

[0035] Combination Figures 1 to 6 Explanation of the working principle of this utility model:
[0036] First, the lifting rod is supported by the limiting notch and limiting bolt on the limiting rod. Due to the weight of the sampling bucket, both lifting rods are subjected to relative component forces along the direction of the limiting rod. The limiting rod on the lifting rod provides support and completes the limiting lock. After moving the equipment to the sampling location, the horizontal bar is pressed down vertically. After the telescopic rod is pressed to its shortest stroke, the bottom of the sampling bucket touches the bottom of the river and is supported. The limiting notch and limiting bolt on the limiting rod automatically separate. Then, the horizontal bar is lifted, the two sampling buckets close, and the sampling operation is completed. The operation is simple and stable, without the need for operators to rely on experience.
