[0019]1. This invention, through the arrangement of an installation frame, a collection frame, a collection partition, a connecting plate, a pushing frame, and a threaded rod, uses a connecting plate to support the threaded rod. The rotation of the threaded rod causes the pushing frame to shift within the installation frame, allowing it to push soil from the installation frame's inner cavity into the collection frame and the collection partition's inner cavity, filling the collection partition's inner cavity with soil. The collection frame and collection partition enable the device to perform basic environmental data collection. After filling the collection partition's inner cavity with soil identical to the external environment and allowing it to stand for a period, the soil environment within the collection partition's inner cavity connects with the external experimental soil environment. This allows for better data collection at different depths within the soil during the removal of the collection frame. Furthermore, the changes in soil environmental data observed by the hydrophobic and thermally conductive frames can be further analyzed based on environmental conditions. By comparing and evaluating biodiversity data with soil depth, this method reduces disturbance to organisms during soil excavation, thus preventing situations where biodiversity information cannot be clearly compared and observed at different soil depths. This improves the accuracy of experimental data collection and addresses the problem that in soil-related experiments, biodiversity information is typically collected through excavation, with evaluation based on the types and quantities of organisms found. However, excavating from shallow to deep soil disturbs organisms and hinders clear comparison and observation of biodiversity information at different depths, thereby affecting the accuracy of experimental data collection.

Abstract
Description
Technical Field
[0001] This invention relates to the field of biodiversity technology, specifically to a biodiversity information collection device and evaluation method. Background Technology
[0002] Biodiversity generally refers to the total number of animals, plants, and microorganisms in an environment. It is also used to describe the quantity and variety of organisms in an experimental environment. The collection of species and quantities of organisms in the environment based on the experimental content can be used to evaluate the biodiversity of the experimental environment.
[0003] In experimental settings involving soil, the collection of information related to biodiversity in the soil is usually done by excavation. The soil is then evaluated based on the types and quantities of organisms found. However, the process of excavating the soil from shallow to deep can disturb the organisms and make it difficult to clearly compare and observe biodiversity information at different depths, thus affecting the accuracy of the experimental data collection. Summary of the Invention
[0004] The purpose of this invention is to provide a biodiversity information collection device and evaluation method, which has the advantage of being easy to collect. It solves the problem that in experimental environments involving soil, the collection of biodiversity-related information and soil data usually involves direct excavation, and the evaluation of the experimental soil is based on the species and quantity of organisms found in the excavated soil. However, the process of excavating the soil from shallow to deep can disturb the organisms in the soil and make it difficult to clearly compare and observe the biodiversity information in the soil environment at different depths, thus affecting the accuracy of experimental information collection.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a biodiversity information collection device, comprising a mounting frame, a collection frame movably connected to the front end of the inner cavity of the mounting frame, a collection partition fixedly connected to the inner cavity of the collection frame, a connecting plate fixedly connected to the front end of the inner cavity of the mounting frame and the back end of the collection frame, a pushing frame movably connected to the rear end of the inner cavity of the mounting frame, threaded rods movably connected to both ends of the front side of the pushing frame, the rear ends of the two threaded rods penetrating the pushing frame and threadedly connected to the inner cavity of the pushing frame, and the front ends of the two threaded rods respectively movably connected to both sides of the back end of the connecting plate via bearings. Next, a vibration motor is installed in the inner cavity of the pushing frame, and a vibration frame is movably connected to the inner cavity of the pushing frame. A pushing plate is fixedly connected to the front of the vibration frame, and one side of the vibration motor is fixedly connected to the back of the pushing plate. Limiting rods are movably connected to both sides of the top and bottom of the vibration frame. The side of the limiting rod near the vibration frame passes through the vibration frame and extends into the inner cavity of the vibration frame, and is movably connected to the inner cavity of the vibration frame. The end of the limiting rod away from the vibration frame is fixedly connected to the inner wall of the pushing frame. A cylinder is fixedly connected to the front end of the bottom of the inner cavity of the mounting frame, and the output end of the cylinder contacts the bottom of the acquisition frame.
[0006] Preferably, a hydrophobic frame is fixedly connected to the front end of the right side of the mounting frame, and a first conduit is fixedly connected to the inner cavity of the hydrophobic frame. The first conduit is located on the surface of the inner cavity of the hydrophobic frame and communicates with a second conduit.
[0007] Preferably, a through groove is provided on the right side of the inner cavity of the collection frame and a filter screen is fixedly connected thereto, and the through groove is connected to the inner cavity of the second conduit.
[0008] Preferably, a heat-conducting frame is fixedly connected to the front end of the left side of the mounting frame, and a heating copper tube is fixedly connected to the inner cavity of the heat-conducting frame.
[0009] Preferably, a limiting plate is fixedly connected to one end of the limiting rod located in the inner cavity of the vibration frame, and springs are sleeved on both the surface of the limiting rod located in the inner cavity of the vibration frame and the surface located outside the vibration frame.
[0010] Preferably, a contact block is fixedly connected to the front of the push plate, and sliding rods are fixedly connected to both sides of the collection frame. Sliding grooves are opened on both sides of the front end of the inner cavity of the mounting frame. One side of the sliding rod extends into the sliding groove of the inner cavity of the mounting frame and is slidably connected to the inner cavity of the sliding groove.
[0011] Preferably, a power frame is fixedly connected to the back of the mounting frame, and pulleys are movably connected to both sides of the front of the inner cavity of the power frame. The rear end of the threaded rod passes through the inner cavity of the power frame and is fixedly connected to the pulleys. A rotary motor is fixedly connected to the back of the inner cavity of the power frame, and the output shaft of the rotary motor is drivenly connected to the back of the left pulley. The two pulleys are connected by belt drive.
[0012] Preferably, the steps for its use are as follows:
[0013] A. First, dig a pit in the soil of the experimental environment to bury the device, bury the device in the pit, cover the device with soil around it and fill it, so that the device is in contact with the soil of the experimental environment.
[0014] B. Pour some soil into the inner cavity of the installation frame, between the pushing frame and the collection frame. Then, start the rotary motor through the external controller. The output shaft of the rotary motor drives the left pulley to rotate. The left pulley drives the right pulley to rotate through the belt. The rotation of the two pulleys drives the two threaded rods to rotate, thereby causing the pushing frame to move forward along with the limit rod, the vibration frame, the pushing plate, and the contact block. At the same time, it pushes the soil between the pushing frame and the collection frame to move, squeezing the soil into the inner cavity of the collection partition. Simultaneously, start the vibration motor through the external controller. The vibration motor vibrates the vibration frame and the pushing plate and causes the contact block to vibrate the soil being pushed, preventing the soil from being over-compressed during the pushing process, which would not be suitable for simulating the natural soil environment required for the experiment.
[0015] C. The operation of the vibrating motor drives the vibrating frame, push plate, and contact block to vibrate, causing the vibrating frame to shift within the push plate's inner cavity and compressing the spring. The spring's restoring force reacts on the vibrating frame, preventing excessive vibration frequency and ensuring proper soil movement. Repeating these steps, after the inner cavity of the sampling partition is filled with soil, fills the inner cavity of the mounting frame with soil, thus completing the soil filling operation for the device.
[0016] D. After completion, in order to increase the experimental observation comparison, external water source is passed through the filter screen and into the soil located on the right side of the collection partition through the first and second conduits to increase the water content of the soil on the right side of the collection partition. At the same time, the heating copper pipe can be activated by the external controller to heat the inner cavity of the heat conduction frame and raise the temperature of the soil around the threaded rod, including the soil on the left side of the inner cavity of the collection partition, thereby changing the soil environment on both sides of the inner cavity of the collection frame to facilitate comparative observation.
[0017] E. After burying the device for a period of time until the expected experimental time interval is reached, activate the cylinder via the external controller. The cylinder's output will push the collection frame and slide rod upwards along the groove inside the mounting frame, reducing the adhesion between the soil inside the collection partition and the soil in the external experimental environment. At this point, the operator can pull the collection frame to quickly remove it from the mounting frame. After removal, biodiversity data can be collected from different areas inside the collection partition. The collection partition allows for comparison of soil samples at different depths. Furthermore, by examining both sides of the collection partition, the biodiversity of organisms in the soil can be observed under different water content and temperature conditions. The study examines the tropism of organisms in the soil, checking whether they tend to prefer environments with higher water content or higher temperatures. Furthermore, it compares the biodiversity of multiple areas within the sampling chamber, thus evaluating the biodiversity and tropism of the experimental environment based on soil samples from various areas within the sampling chamber. The process involves quickly removing the sampling frame from the inner cavity of the installation frame, minimizing disturbance to the organisms during soil excavation. This prevents situations where biodiversity information at different soil depths cannot be clearly compared and observed, thereby improving the accuracy of experimental data collection.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0019] 1. This invention, through the arrangement of an installation frame, a collection frame, a collection partition, a connecting plate, a pushing frame, and a threaded rod, uses a connecting plate to support the threaded rod. The rotation of the threaded rod causes the pushing frame to shift within the installation frame, allowing it to push soil from the installation frame's inner cavity into the collection frame and the collection partition's inner cavity, filling the collection partition's inner cavity with soil. The collection frame and collection partition enable the device to perform basic environmental data collection. After filling the collection partition's inner cavity with soil identical to the external environment and allowing it to stand for a period, the soil environment within the collection partition's inner cavity connects with the external experimental soil environment. This allows for better data collection at different depths within the soil during the removal of the collection frame. Furthermore, the changes in soil environmental data observed by the hydrophobic and thermally conductive frames can be further analyzed based on environmental conditions. By comparing and evaluating biodiversity data with soil depth, this method reduces disturbance to organisms during soil excavation, thus preventing situations where biodiversity information cannot be clearly compared and observed at different soil depths. This improves the accuracy of experimental data collection and addresses the problem that in soil-related experiments, biodiversity information is typically collected through excavation, with evaluation based on the types and quantities of organisms found. However, excavating from shallow to deep soil disturbs organisms and hinders clear comparison and observation of biodiversity information at different depths, thereby affecting the accuracy of experimental data collection.
[0020] 2. This invention incorporates a vibration motor, a vibration frame, a push plate, a limiting rod, and a cylinder. The vibration motor adds vibration functionality to the device. The vibration of the motor, in conjunction with the push plate and vibration frame, allows the contact block to vibrate and loosen the soil within the collection partition cavity, preventing excessive soil compression when the contact block and push plate push the soil within the installation frame cavity. This allows the device to simulate the experimental soil environment as closely as possible. The limiting rod limits the vibration of the vibration frame and push plate within the push frame cavity, preventing excessive vibration amplitude. The cylinder facilitates the initial pushing function of the collection frame, making it convenient for staff to retrieve the collection frame and, in conjunction with the collection partition, collect biodiversity information from the soil.

Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0029] Please see Figure 1-5A biodiversity information collection device includes a mounting frame 1, a collection frame 2 movably connected to the front end of the inner cavity of the mounting frame 1, a collection partition 3 fixedly connected to the inner cavity of the collection frame 2, a connecting plate 4 fixedly connected to the front end of the inner cavity of the mounting frame 1 and the back end of the collection frame 2, a pushing frame 5 movably connected to the rear end of the inner cavity of the mounting frame 1, threaded rods 6 movably connected to both ends of the front side of the pushing frame 5, the rear ends of the two threaded rods 6 penetrating the pushing frame 5 and threadedly connected to the inner cavity of the pushing frame 5, the front ends of the two threaded rods 6 respectively movably connected to the two sides of the back end of the connecting plate 4 via bearings, a vibration motor 7 disposed in the inner cavity of the pushing frame 5, a vibration frame 8 movably connected to the inner cavity of the pushing frame 5, a pushing plate 9 fixedly connected to the front side of the vibration frame 8, and the vibration motor... One side of the 7 is fixedly connected to the back of the push plate 9. Limiting rods 10 are movably connected to both sides of the top and bottom of the vibration frame 8. The side of the limiting rod 10 closest to the vibration frame 8 passes through the vibration frame 8 and extends into the inner cavity of the vibration frame 8, and is movably connected to the inner cavity of the vibration frame 8. The end of the limiting rod 10 away from the vibration frame 8 is fixedly connected to the inner wall of the push frame 5. A cylinder 11 is fixedly connected to the front end of the bottom of the inner cavity of the mounting frame 1. The output end of the cylinder 11 contacts the bottom of the acquisition frame 2. By setting up the mounting frame 1, acquisition frame 2, acquisition partition 3, connecting plate 4, push frame 5, and threaded rod 6, the connecting plate 4 achieves the effect of supporting the threaded rod 6. The rotation of the threaded rod 6 will cause the push frame 5 to move within the inner cavity of the mounting frame 1, and allow the push frame... 5. The soil located inside the mounting frame 1 can be pushed into the inner cavity of the collection frame 2 and the collection partition 3. The inner cavity of the collection partition 3 is filled with soil. The collection frame 2 and the collection partition 3 enable the device to have basic environmental collection functions. After filling the inner cavity of the collection partition 3 with soil that is the same as the external environment and letting it stand for a period of time, the soil environment inside the collection partition 3 is connected with the external experimental soil environment. In this way, during the process of removing the collection frame 2, the collection partition 3 and the soil inside the collection partition 3 can be better collected from different depths in the soil. The changes in soil environmental data in the hydrophobic frame 12 and the heat-conducting frame 16 can be further compared and evaluated based on the environmental data and soil depth, reducing the need for digging experimental soil. During the excavation process, the organisms in the soil are disturbed, thus preventing the inability to clearly compare and observe biodiversity information at different soil depths. This improves the accuracy of experimental data collection and solves the problem that in soil-related experimental environments, the collection of biodiversity-related information and soil data usually involves direct excavation, and the evaluation of the experimental soil is based on the types and quantities of organisms found. However, the process of excavating soil from shallow to deep can disturb the organisms in the soil and prevent a clear comparison and observation of biodiversity information at different soil depths, thereby affecting the accuracy of experimental data collection.
[0030] Specifically, a hydrophobic frame 12 is fixedly connected to the front end of the right side of the mounting frame 1. A first conduit 13 is fixedly connected to the inner cavity of the hydrophobic frame 12. The first conduit 13 is located on the surface of the inner cavity of the hydrophobic frame 12 and is connected to a second conduit 14. By setting up the hydrophobic frame 12, the first conduit 13 and the second conduit 14, it is convenient to add water to the soil on the right side of the inner cavity of the collection partition 3, thereby changing the experimental environment.
[0031] Specifically, a through groove is provided on the right side of the inner cavity of the collection frame 2 and a filter screen 15 is fixedly connected thereto. The through groove is connected to the inner cavity of the second conduit 14. By setting the filter screen 15, a large amount of soil is prevented from entering the inner cavities of the second conduit 14 and the first conduit 13.
[0032] Specifically, a heat-conducting frame 16 is fixedly connected to the front end of the left side of the mounting frame 1, and a heating copper tube 17 is fixedly connected to the inner cavity of the heat-conducting frame 16. By setting the heat-conducting frame 16 and the heating copper tube 17, a temperature rise function is added to one side of the device, which also changes the experimental environment data, making it convenient for comparison and observation.
[0033] Specifically, a limiting plate 18 is fixedly connected to one end of the limiting rod 10 located in the inner cavity of the vibration frame 8. Springs 19 are sleeved on both the surface of the limiting rod 10 located in the inner cavity of the vibration frame 8 and the surface located on the outer end of the vibration frame 8. By setting the limiting plate 18 and the springs 19, a reset function and a limiting function are added to the limiting rod 10 and the vibration frame 8.
[0034] Specifically, a contact block 20 is fixedly connected to the front of the push plate 9, and a slide rod 21 is fixedly connected to both sides of the collection frame 2. Slide grooves are opened on both sides of the front end of the inner cavity of the mounting frame 1. One side of the slide rod 21 extends into the slide groove of the inner cavity of the mounting frame 1 and slides in connection with the inner cavity of the slide groove. By setting the contact block 20 and the slide rod 21, the contact block 20 facilitates the contact between the push plate 9 and the soil, and the slide rod 21 limits the lifting and lowering of the collection frame 2.
[0035] Specifically, a power frame 22 is fixedly connected to the back of the mounting frame 1. Pulleys 23 are movably connected to both sides of the front of the inner cavity of the power frame 22. The rear end of the threaded rod 6 passes through the inner cavity of the power frame 22 and is fixedly connected to the pulleys 23. A rotary motor 24 is fixedly connected to the back of the inner cavity of the power frame 22. The output shaft of the rotary motor 24 is connected to the back of the left pulley 23. The two pulleys 23 are connected by belt drive. By setting up the power frame 22, pulleys 23 and rotary motor 24, power is provided for the rotation of the two threaded rods 6.
[0036] Specifically, the steps for using it are as follows:
[0037] A. First, dig a pit in the soil of the experimental environment to bury the device, bury the device in the pit, cover the device with soil around it and fill it, so that the device is in contact with the soil of the experimental environment.
[0038] B. Pour some soil into the inner cavity of the installation frame 1, between the pushing frame 5 and the collection frame 2. Then, start the rotary motor 24 through the external controller. The output shaft of the rotary motor 24 drives the left pulley 23 to rotate. The left pulley 23 drives the right pulley 23 to rotate through the belt. The rotation of the two pulleys 23 drives the two threaded rods 6 to rotate, thereby causing the pushing frame 5 to move forward along the limit rod 10, the vibration frame 8, the pushing plate 9 and the contact block 20. At the same time, it pushes the soil between the pushing frame 5 and the collection frame 2 to move, squeezing the soil into the inner cavity of the collection partition 3. At the same time, start the vibration motor 7 through the external controller. The vibration motor 7 vibrates the vibration frame 8 and the pushing plate 9 and causes the contact block 20 to vibrate the pushed soil, preventing the soil from being over-compressed during the pushing process, which would not be suitable for simulating the natural soil environment required for the experiment.
[0039] C. The operation of the vibration motor 7 drives the vibration frame 8, the push plate 9, and the contact block 20 to vibrate, causing the vibration frame 8 to shift within the inner cavity of the push frame 5 and compressing the spring 19. The restoring force of the spring 19 reacts on the vibration frame 8, preventing the vibration frequency of the vibration frame 8 from being too fast and affecting the pushing of the soil. Repeat the above steps until the inner cavity of the collection partition 3 is filled with soil, and then use soil to fill the inner cavity of the mounting frame 1, thus completing the soil filling operation of the device.
[0040] D. After completion, in order to increase the experimental observation comparison, external water source is passed through the first conduit 13 and the second conduit 14 to pass through the filter screen 15 and flow into the soil located on the right side of the collection partition 3, increasing the water content of the soil on the right side of the collection partition 3. At the same time, the heating copper pipe 17 can be activated by the external controller to heat the inner cavity of the heat conduction frame 16, and the soil around the threaded rod 6, including the soil on the left side of the inner cavity of the collection partition 3, will be heated, thereby changing the soil environment on both sides of the inner cavity of the collection frame 2, which is convenient for comparative observation.
[0041] E. After burying the device for a period of time until the expected experimental time interval is reached, start cylinder 11 via the external controller. The output of cylinder 11 pushes the collection frame 2 and slide rod 21 upward along the sliding groove inside the mounting frame 1, reducing the adhesion between the soil inside the collection partition 3 and the soil in the external experimental environment. At this time, the staff can pull the collection frame 2 to quickly pull it out of the mounting frame 1. After pulling it out, biodiversity data can be collected from different areas inside the collection partition 3. The collection partition 3 can be used to compare soil at different depths. At the same time, the different water content and temperature conditions can be observed on both sides of the collection partition 3. The study examines the directional behavior of organisms in the soil, checking whether they tend to prefer environments with higher water content or higher temperatures. Furthermore, it compares the biodiversity of multiple areas within the cavity of the sampling partition 3, thereby evaluating the biodiversity and directional behavior of the experimental soil based on the soil samples from multiple areas within the cavity of the sampling partition 3. During the process, the sampling frame 2 is quickly pulled out of the cavity of the installation frame 1, reducing disturbance to the organisms in the soil during excavation. This prevents situations where biodiversity information at different soil depths cannot be clearly compared and observed, thus improving the accuracy of experimental data collection.

B. Pour some soil into the inner cavity of the installation frame (1) and place it between the push frame (5) and the collection frame (2). Then, start the rotary motor (24) through the external controller. The output shaft of the rotary motor (24) drives the left pulley (23) to rotate. The left pulley (23) drives the right pulley (23) to rotate through the belt. The rotation of the two pulleys (23) drives the two threaded rods (6) to rotate. This causes the push frame (5) to move forward along the limit rod (10), the vibration frame (8), the push plate (9), and the contact block (20). At the same time, it pushes the soil between the push frame (5) and the collection frame (2) to move and squeeze the soil into the inner cavity of the collection partition (3). At the same time, start the vibration motor (7) through the external controller. The vibration motor (7) vibrates the vibration frame (8) and the push plate (9) and causes the contact block (20) to vibrate the soil being pushed. This prevents the soil from being over-compressed during the pushing process, which would not be suitable for simulating the natural soil environment required for the experiment. C. The operation of the vibration motor (7) drives the vibration frame (8), the push plate (9) and the contact block (20) to vibrate. At the same time, the vibration frame (8) will move within the inner cavity of the push frame (5) and squeeze the spring (19). The restoring force of the spring (19) will react on the vibration frame (8) to prevent the vibration frequency of the vibration frame (8) from being too fast and affecting the pushing of the soil. Repeat the above steps to fill the inner cavity of the collection partition (3) with soil, and then fill the inner cavity of the mounting frame (1) with soil to complete the soil filling operation of the device. D. After completion, in order to increase the experimental observation comparison, external water source is passed through the first conduit (13) and the second conduit (14) to pass through the filter screen (15) and flow into the soil located on the right side of the collection partition (3), increasing the water content of the soil on the right side of the collection partition (3). At the same time, the heating copper pipe (17) can be started by the external controller to heat the inner cavity of the heat conduction frame (16), and the soil around the threaded rod (6) including the left side of the inner cavity of the collection partition (3) will be heated, thereby changing the soil environment on both sides of the inner cavity of the collection frame (2) to facilitate comparative observation. E. After burying the device for a period of time, once the expected time interval of the experiment is reached, start the cylinder (11) through the external controller. The output end of the cylinder (11) pushes the collection frame (2) and the slide rod (21) to move upward along the slide groove in the inner cavity of the mounting frame (1), so that the soil in the inner cavity of the collection partition (3) and the soil in the external experimental environment are less cohesive. At this time, the staff can pull the collection frame (2) and quickly pull the collection frame (2) out of the inner cavity of the mounting frame (1). After the collection frame (2) is pulled out, the soil in different areas of the inner cavity of the collection partition (3) can be collected for biodiversity. The soil at different depths can be compared through the collection partition (3). At the same time, the water content can be checked on both sides of the inner cavity of the collection partition (3). Under different temperature conditions, the tendency of organisms in the soil is examined to see if organisms tend to be more inclined to environments with higher water content or higher temperature. Furthermore, the biodiversity of multiple areas inside the cavity of the sampling partition (3) is compared, so as to achieve the effect of evaluating the biodiversity of the experimental environment soil and the tendency of organisms based on the soil in multiple areas inside the cavity of the sampling partition (3). During the process, by quickly pulling the sampling frame (2) out of the cavity of the installation frame (1), the situation of disturbing the organisms in the soil during the excavation of the experimental soil is reduced, thereby preventing the situation of not being able to clearly compare and observe the biodiversity information in soil environments at different depths, thus improving the accuracy of experimental information collection.
