[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0020] Please see Figures 1-5 This utility model provides a technical solution: a solid waste sampling device for environmental monitoring, including a support frame 1, a first screw 2 rotatably connected to the inner cavity of the upper end of the support frame 1, the outer wall of the first screw 2 being threadedly connected to the inner wall of the moving block 3, and the outer wall of the moving block 3 being engaged with the inner cavity of the upper end of the support frame 1, and the inner wall of the upper end of the support frame 1 being engaged with the outer wall of the sampling mechanism 5.
[0021] The sampling mechanism 5 includes a limiting plate 51, a moving plate 511, a second screw 53, a sampling frame 54, a sliding groove 55, and a drain plate 56. The outer wall of the limiting plate 51 is engaged with the inner wall of the upper end of the support frame 1, and a support plate is installed on the upper end of the limiting plate 51, which overlaps with the upper end face of the support frame 1. The upper end of the moving plate 511 is fixedly connected to the lower end of the limiting plate 51. The two ends of the second screw 53 are rotatably connected to the inner cavity of the moving plate 511. The two ends of the sampling frames 54 that are far apart from each other are engaged with the inner cavity of the moving plate 511, and the two ends of the sampling frames 54 that are far apart from each other are threadedly connected to the outer wall of the second screw 53. A drain hole is opened on the lower end face of the inner cavity of the sampling frame 54. The sliding groove 55 is opened on the lower end face of the inner cavity of the sampling frame 54. The lower end of the drain plate 56 is engaged with the inner cavity of the sliding groove 55.
[0022] The rotation of the second screw 53 causes the sampling frame 54 to move downwards. At this time, the rotation of the first screw 2 causes the moving blocks 3 to move closer together, which in turn causes the moving plates 511 to move closer together. The moving plates 511 moving closer together drive the sampling frame 54 to move closer together, thereby picking up the solid waste. When the sampling frame 54 picks up the solid waste, the drain plate 56 installed inside the sampling frame 54 squeezes and drains the solid waste, thereby removing the waste liquid inside the solid waste, preventing the waste liquid from affecting the analysis of the solid waste composition, and ensuring the accuracy of the solid waste test results.
[0023] Specifically, one end of the support frame 1 is fixedly connected to the first motor 4, and the output end of the first motor 4 is fixedly connected to one end of the first screw 2, and the outer wall of the first screw 2 is fitted with a reverse thread.
[0024] The rotation of the first motor 4 causes the first screw 2 to rotate. At the same time, the surface of the first screw 2 is equipped with reverse threads. The rotation of the first screw 2 causes the moving blocks 3 to move closer to each other. The movement of the moving blocks 3 causes the second motor 52 to move, thereby ensuring the stability of the movement of the moving plate 511 and ensuring the stability of the device in sampling solid waste. This eliminates the need for manual operation and saves manpower.
[0025] Specifically, the sampling mechanism 5 includes a second motor 52 and a spring 57. The upper end of the second motor 52 is fixedly connected to the lower end of the moving block 3, and the output end of the second motor 52 is fixedly connected to the upper end of the second screw 53. The ends of the springs 57 that are far apart from each other are fixedly connected to one end of the inner cavity of the slide groove 55, and the ends of the springs 57 that are close to each other are fixedly connected to the ends of the drain plate 56 that are far apart from each other.
[0026] When the drain plate 56 squeezes and drains the solid waste, it causes the drain plates 56 to move away from each other, thereby squeezing the spring 57. At this time, the elastic force of the spring 57 increases the squeezing force of the drain plate 56 on the solid waste, thus improving the efficiency of solid waste drainage. The second screw 53 can be rotated by starting the second motor 52, which in turn causes the sampling frame 54 to move up and down, thus eliminating the need for manual operation and saving manpower. At the same time, the rotation of the first motor 4 causes the first screw 2 to rotate, which in turn causes the moving block 3 to move. The movement of the moving block 3 causes the second motor 52 to move, thus ensuring the stability of the movement of the moving plate 511.
[0027] Specifically, a limit rod is installed in the inner cavity of the slide 55, and the outer wall of the limit rod is movably connected to the inner cavity of the spring 57 and the inner wall of the lower end of the drain plate 56.
[0028] The limiting rod allows the drain plate 56 to move horizontally, thus ensuring that the drain plate 56 can stably squeeze and drain solid waste when it moves.
[0029] Specifically, the upper end of the drain plate 56 is arc-shaped, and a piercing rod is installed at one end of the drain plate 56 that is close to each other.
[0030] The drain plate 56 is arc-shaped, which allows it to adapt to solid waste of different shapes. The piercing rod installed on the surface of the drain plate 56 can pierce the solid waste, thereby facilitating the discharge of waste liquid inside the solid waste.
[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
