A soil particle analysis device for water erosion detection Technical Field
[0001] This utility model relates to the field of water erosion detection technology, specifically a soil particle analysis device for water erosion detection. Background Technology
[0002] Soil erosion, especially water erosion, is one of the major environmental problems worldwide leading to land degradation, reduced agricultural yields, and ecological deterioration. With the intensification of global climate change and the increasing frequency of human activities, soil water erosion is becoming increasingly severe, posing a serious challenge to ecosystem service functions and the sustainable development of human society. Therefore, accurate monitoring and assessment of soil water erosion are of great significance for formulating effective soil and water conservation strategies, protecting land resources, and maintaining ecological balance. In soil water erosion research, soil particle size analysis is a fundamental and crucial task. Soil particle composition not only reflects the basic physical properties of soil but also directly affects soil erosion resistance, water retention capacity, and nutrient cycling processes.
[0003] Currently, most soil particle analysis equipment on the market adopts traditional sieving methods, achieving particle separation through simple linear vibration or static sedimentation. These devices have significant shortcomings: First, traditional linear vibration sieving is inefficient, and soil particles are difficult to disperse fully on the screen, easily leading to problems such as large particles clogging the screen holes and small particles not being thoroughly sieved, resulting in large errors in the analysis results; Second, the existing equipment has a single sieving motion mode, which cannot simulate the complex motion state of soil particles in natural environments, making it difficult to meet the needs of accurate separation of particles of different sizes in water erosion detection.
[0004] Therefore, this invention provides a soil particle analysis device for water erosion detection to solve the problems mentioned above. Summary of the Invention
[0005] The purpose of this invention is to provide a soil particle analysis device for water erosion detection, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A soil particle analysis device for water erosion detection includes a base, characterized in that: the upper surface of the base is equipped with the main body of the soil analysis device and a sieving mechanism; the upper surface of the base is equipped with a driving mechanism for driving the sieving mechanism to swing up and down and back and forth; the outer end of the sieving mechanism is equipped with a pressing mechanism for shaking the soil particles inside the sieving mechanism; the sieving mechanism includes a sieve box; three sets of fixed plates are slidably connected inside the sieve box; elastic cloth is installed inside the fixed plates; and filter screens are installed inside the elastic cloth.
[0008] As a further embodiment of this utility model, the driving mechanism includes a side plate and a guide rail. The side plate and the guide rail are both installed on the upper surface of the base. A rotating rod 1 and a rotating rod 2 are rotatably connected inside the side plate. An L-shaped push rod is installed on the outer surface of the rotating rod 1. A slide bar is slidably connected inside the guide rail. A positioning block, a connecting rod 3, and a fixing rod are installed on the upper surface of the slide bar. A fixing ring is installed at the outer end of the rotating rod 2. Connecting rod 1 and connecting rod 2 are installed on the outer surface of the fixing ring. The positioning block is located on the rotation path of connecting rod 1. The positions of connecting rod 3 and connecting rod 2 are both located on the rotation path of the L-shaped push rod. The front end of the fixing rod is slidably connected to the back of the base. Two sets of connecting plates are installed on the upper surface of the base. Pulleys are rotatably connected inside the connecting plates. The two sets of pulleys are rotatably connected to the left and right sides of the screen box, respectively.
[0009] As a further embodiment of this utility model, the pressing mechanism includes a magnetic strip and two sets of magnetic blocks. Both sets of magnetic blocks are slidably connected to the inner wall of the back of the sieve box. The magnetic strip is slidably connected to the inside of the upper surface of the base. The back of the two sets of magnetic blocks is attracted to the front end of the magnetic strip. An L-shaped connecting rod is installed on the front of the magnetic block. A pressure rod is installed on the lower surface of the L-shaped connecting rod. The two sets of pressure rods are located at the top of the two sets of filter screens.
[0010] As a further improvement of this utility model, a fixing frame is installed on the left and right sides of the pressure rod.
[0011] As a further improvement of this utility model, a pull rod is installed on the front of the three sets of fixing plates.
[0012] As a further embodiment of this utility model, a storage box is slidably connected inside the sieve box, and the storage box is located at the lower end of the three sets of filter screens.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In use, this utility model involves pushing the handle to rotate the first rotating rod and the L-shaped push rod. During rotation, the L-shaped push rod pushes the third connecting rod and the positioning block to swing back and forth on the upper end of the guide rail. This causes the slide bar to pull the fixed rod, causing the screen box to swing back and forth on the upper end of the base. The screen box is then connected to the slide rail of the connecting plate by a pulley. As the screen box swings back and forth, it pulls the pulley to roll inside the slide rail of the connecting plate. This causes the pulley to swing the screen box up and down between the two sets of connecting plates, thereby accelerating the screening of soil particles inside the screen box and improving the practicality of the device.
[0015] 2. In use, this utility model uses a magnetic block that slides inside the slot of the sieve box and is magnetically attached to the front end of the magnetic strip. This allows the upper surface of the filter screen and the lower surface of the pressure rod to come into contact as the sieve box moves upward. The elastic cloth, with its good extensibility, stretches as the filter screen is pressed. When the sieve box resets, the elastic cloth pulls the filter screen to automatically reset using its own contraction. This high-frequency vibration of the filter screen during the reset process accelerates the sieving speed and shortens the time spent sieving soil particles, thus improving the practicality of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 4. In this embodiment of the present invention, a soil particle analysis device for water erosion detection includes a base 1. The base 1 is characterized in that: a soil analysis device body 2 and a sieving mechanism 12 are installed on the upper surface of the base 1; a driving mechanism 9 is installed on the upper surface of the base 1 to drive the sieving mechanism 12 to swing up and down and back and forth; a pressing mechanism 8 is installed at the outer end of the sieving mechanism 12 to drive the soil particles inside the sieving mechanism 12 to shake; the sieving mechanism 12 includes a sieve box 3; three sets of fixing plates 4 are slidably connected inside the sieve box 3; an elastic cloth 11 is installed inside the fixing plate 4; and a filter screen 5 is installed inside the elastic cloth 11.
[0023] Specifically, by pushing the drive mechanism 9 to pull the sieve box 3 to swing back and forth on the upper end of the base 1, the drive mechanism 9 accelerates the sieving of soil particles inside the sieve box 3, thereby shortening the time spent by the staff when using the device to analyze soil particles, thus improving the practicality of the device.
[0024] Please refer to Figures 1-4. The drive mechanism 9 includes a side plate 901 and a guide rail 909. Both the side plate 901 and the guide rail 909 are mounted on the upper surface of the base 1. Rotating rod 1 903 and rotating rod 2 904 are rotatably connected inside the side plate 901. An L-shaped push rod 905 is mounted on the outer surface of rotating rod 1 903. A slide bar 910 is slidably connected inside the guide rail 909. A positioning block 908, a connecting rod 3 915, and a fixing rod 914 are mounted on the upper surface of the slide bar 910. A fixing ring 912 is mounted on the outer end of rotating rod 2 904. Connecting rod 1 911 and connecting rod 2 913 are mounted on the outer surface of the fixing ring 912. The positioning block 908 is located on the rotation path of connecting rod 1 911. The positions of connecting rod 3 915 and connecting rod 2 913 are both located on the rotation path of the L-shaped push rod 905. The front end of the fixed rod 914 is slidably connected to the back of the base 1. Two sets of connecting plates 906 are installed on the upper surface of the base 1. Pulleys 907 are rotatably connected inside the connecting plates 906. The two sets of pulleys 907 are rotatably connected to the left and right sides of the screen box 3 respectively. A handle 902 is installed on the outer end of the rotating rod 903. Two sets of grooves are opened inside the side plate 901. The rotating rod 903 and the rotating rod 904 are rotatably connected inside the two sets of grooves of the side plate 901 respectively. A slide rail is opened inside the connecting plate 906. The pulleys 907 are rotatably connected inside the slide rail of the connecting plate 906. Through holes are opened on both the left and right sides of the screen box 3. The pulleys 907 are rotatably connected inside the through holes of the screen box 3. A positioning groove is opened on the back of the screen box 3. The front end of the fixed rod 914 is slidably connected inside the positioning groove of the screen box 3.
[0025] Specifically, by pushing the handle 902, the rotating rod 903 and the L-shaped push rod 905 are rotated. During the rotation, the L-shaped push rod 905 pushes the connecting rod 915 and the positioning block 908 to swing back and forth on the upper end of the guide rail 909. This causes the slide bar 910 to pull the fixing rod 914, which in turn causes the screen box 3 to swing back and forth on the upper end of the base 1. Then, the pulley 907 is rolled inside the slide rail of the connecting plate 906. During the back and forth swing, the screen box 3 pulls the pulley 907 to roll inside the slide rail of the connecting plate 906. This causes the pulley 907 to drive the screen box 3 to swing up and down between the two sets of connecting plates 906, thereby accelerating the screening of soil particles inside the screen box 3 and improving the practicality of the device.
[0026] Please refer to Figures 1 to 3. The pressing mechanism 8 includes a magnetic strip 801 and two sets of magnetic blocks 802. The two sets of magnetic blocks 802 are slidably connected to the inner wall of the back of the sieve box 3. The magnetic strip 801 is slidably connected to the inside of the upper surface of the base 1. The back of the two sets of magnetic blocks 802 is attracted to the front end of the magnetic strip 801. An L-shaped connecting rod 803 is installed on the front of the magnetic block 802. A pressure rod 804 is installed on the lower surface of the L-shaped connecting rod 803. The two sets of pressure rods 804 are located at the top of the two sets of filter screens 5. A slot is opened on the inner wall of the back of the sieve box 3. The two sets of magnetic blocks 802 are slidably connected to the slot of the sieve box 3. A groove is opened on the upper surface of the base 1. The magnetic strip 801 is slidably connected to the groove of the base 1.
[0027] Specifically, the magnetic block 802 is slidably connected inside the slot of the sieve box 3 and magnetically attracted to the front end of the magnetic strip 801. This allows the upper surface of the filter screen 5 to contact the lower surface of the pressure rod 804 during the upward movement of the sieve box 3. The elastic cloth 11, with its good extensibility, stretches when the filter screen 5 is pressed. During the resetting process of the sieve box 3, the elastic cloth 11, with its own contraction, pulls the filter screen 5 to automatically reset. This high-frequency vibration of the filter screen 5 during resetting accelerates the sieving speed, shortening the time spent sieving soil particles and improving the practicality of the device. The magnetic strip 801 is slidably connected inside the groove of the base 1, allowing the magnetic strip 801 to slide synchronously within the groove during the forward and backward movement of the sieve box 3, thus minimizing obstruction of the sieve box 3's forward and backward swing.
[0028] Please refer to Figures 2 and 3. Fixing frames 10 are installed on the left and right sides of the pressure rod 804. The fixing frames 10 are located at the top of the filter screen 5, and the outer surface of the fixing frames 10 is parallel to the outer surface of the filter screen 5.
[0029] Specifically, by keeping the position of the outer surface of the fixed frame 10 parallel to the position of the outer surface of the filter screen 5, the fixed frame 10 restricts the movement path of the filter screen 5 during the pressing of the filter screen 5 by the pressure rod 804, thereby minimizing the risk of the elastic cloth 11 pulling on the four corners of the filter screen 5 during the extension process, which would cause the inner diameter of the filter holes inside the filter screen 5 to expand.
[0030] Please refer to Figure 2. Pull rods 7 are installed on the front of the three sets of fixing plates 4.
[0031] Specifically, by installing the pull rod 7 inside the three sets of fixed plates 4, the staff can move the three sets of fixed plates 4 simultaneously when pulling the pull rod 7, thereby preventing soil particles deposited on the upper part of the upper fixed plate 4 from falling to the upper part of the lower filter screen 5 when the staff pulls the fixed plate 4 alone.
[0032] Please refer to Figure 2. A storage box 6 is slidably connected inside the sieve box 3. The storage box 6 is located directly below the three sets of filter screens 5. A groove is provided on the front of the sieve box 3, and the storage box 6 is slidably connected inside the groove of the sieve box 3.
[0033] Specifically, the storage box 6 is installed at the lower end of the three sets of filter screens 5, so that the storage box 6 can collect the soil particles that fall off after being filtered by the filter screens 5 and during the movement of the fixing plate 4. Then, by pulling the storage box 6, the storage box 6 is moved out of the screen box 3, so that the staff can quickly clean up the soil particles that have fallen to the bottom of the screen box 3, thereby avoiding the accumulation of too many soil particles at the bottom of the screen box 3, which would prevent the subsequent screening mechanism 12 from being used normally.
[0034] The working principle of this utility model is as follows:
[0035] In use, pushing the handle 902 drives the rotating rod 903 and the L-shaped push rod 905 to rotate. During rotation, the L-shaped push rod 905 pushes the connecting rod 915 and the positioning block 908 to swing back and forth on the upper end of the guide rail 909. This causes the slide bar 910 to pull the fixing rod 914, causing the screen box 3 to swing back and forth on the upper end of the base 1. Then, the pulley 907 is rolled inside the slide rail of the connecting plate 906. During the back-and-forth swinging, the screen box 3 pulls the pulley 907 to roll inside the slide rail of the connecting plate 906, causing the pulley 907 to swing up and down between the two sets of connecting plates 906, thereby increasing... The screen box 3 is rapidly sieved to separate soil particles. A magnetic block 802 is slidably connected to the slot of the screen box 3 and magnetically attached to the front end of the magnetic strip 801. As the screen box 3 moves upward, the upper surface of the filter screen 5 contacts the lower surface of the pressure rod 804. The elastic cloth 11, with its good extensibility, stretches as the filter screen 5 is pressed. When the screen box 3 resets, the elastic cloth 11 uses its own contraction to pull the filter screen 5 back to its original position. This high-frequency vibration of the filter screen 5 during reset further accelerates the sieving speed.
[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
