Description

Technical Field

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

[0002] With the increasing awareness of ecological and environmental protection and the increasingly stringent relevant policies and regulations, accurate monitoring of the ecological environment is becoming more and more crucial. As an important component of the ecosystem, soil plays an irreplaceable role in assessing the quality of the ecological environment, monitoring soil pollution, and studying the functions of the soil ecosystem. This necessitates efficient and accurate soil sampling devices to obtain representative soil samples.

[0003] However, existing soil sampling devices used for ecological and environmental monitoring are not easy to clean when in use. Residual samples from previous samplings can mix into the soil samples collected next time, causing changes in the composition and properties of the samples, thus affecting the accurate assessment of soil pollution status. Utility Model Content

[0004] The purpose of this invention is to provide a soil sampling device for ecological environment monitoring. By setting up a discharge cleaning mechanism, it solves the problem that existing soil sampling devices for ecological environment monitoring are inconvenient to clean during use, and residual samples from previous collections will mix into the soil samples collected next time, causing changes in the composition and properties of the samples, thus affecting the accurate judgment of soil pollution status.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a soil sampling device for ecological environment monitoring, including a base plate, on which a material discharge cleaning mechanism and a pressing mechanism are provided;

[0007] The discharge cleaning mechanism includes a U-shaped support frame fixedly connected to the top of the base plate. The left and right inner walls of the U-shaped support frame are provided with rectangular sliding grooves. Rectangular sliders are slidably connected to the inner walls of the two rectangular sliding grooves. A support frame is fixedly connected between the two rectangular sliders. A sampling box is fixedly connected to the inner wall of the support frame. The bottom of the sampling box penetrates the base plate and is slidably connected to the base plate. The pressing mechanism includes a rectangular mounting groove opened at the top of the U-shaped support frame. The bottom of the rectangular mounting groove penetrates the U-shaped support frame.

[0008] Furthermore, the inner wall of the sampling box is provided with a spiral groove, and a circular slider is slidably connected to the inner wall of the spiral groove. A pressure plate is provided inside the sampling box, and the outer wall of the pressure plate is in contact with the sampling box. The outer wall of the pressure plate is fixedly connected to the circular slider. Several cleaning rods are fixedly connected to the bottom of the pressure plate, and the sides of the several cleaning rods that are far apart from each other are in contact with the sampling box.

[0009] Furthermore, a U-shaped support frame two is fixedly connected to the top of the sampling box, and a hydraulic cylinder one is fixedly connected to the inner wall of the U-shaped support frame two. The output shaft of the hydraulic cylinder one extends into the bottom plate, and the output shaft of the hydraulic cylinder one is rotatably connected to the pressure plate. Several universal wheels are provided at the bottom of the bottom plate.

[0010] Furthermore, a rectangular sliding groove 2 is provided on the inner wall of the right side of the rectangular mounting groove 2. Two rectangular sliders 2 are slidably connected to the inner wall of the rectangular sliding groove 2. Two hinge blocks are hinged in the rectangular mounting groove 2. The rear sides of the two hinge blocks are respectively fixedly connected to the two rectangular sliders 2. A hydraulic cylinder 2 is fixedly connected to the rear side of the hinge block on the right side. The output shaft of the hydraulic cylinder 2 is fixedly connected to the hinge block on the left side.

[0011] Furthermore, each of the two hinge blocks has a hinge rod 1 hinged to its bottom, and each of the two hinge rod 1s has a hinge rod 2 hinged to its bottom, with the bottom of each of the two hinge rod 2s hinged to the support frame.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a discharge cleaning mechanism, when discharging, hydraulic cylinder one is opened and its stretching is controlled. The output shaft of hydraulic cylinder one drives the pressure plate to descend. When the pressure plate descends, it drives the circular slider to slide in the spiral groove. Under the limit of the spiral groove, the circular slider will make a circular motion around the central axis of the sampling box while descending, thereby driving the pressure plate to rotate. The pressure plate drives several cleaning rods below it to scrape the inner wall of the sampling box, thereby cleaning the inner wall of the sampling box while discharging the soil sample. This allows the sampling box to be cleaned while discharging the soil sample, thus avoiding the situation where residual samples from the previous collection are mixed into the soil sample collected next time, causing changes in the composition and properties of the sample, which would affect the accurate judgment of the soil pollution status.

[0014] 2. By setting up a pressing mechanism, the device is first moved to the designated position using the casters. Then, the second hydraulic cylinder in the rectangular mounting slot is activated to control its extension. The second hydraulic cylinder drives the two hinge blocks to move away from each other under the limit of the two rectangular sliders, thereby driving the first and second hinge rods below to rotate. The two second hinge rods drive the sampling box to descend through the support frame, so that the sampling box is inserted into the soil below. Then, the second hydraulic cylinder is controlled to retract, and the sampling box is driven to rise through a similar transmission, thereby bringing out the soil sample. This allows stable pressure to penetrate the ground in areas with large terrain undulations and uneven soil hardness, such as mountains and hills, thus overcoming the sampling obstacles caused by complex terrain.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The pressing mechanism 3 includes a rectangular mounting groove 311 formed at the top of a U-shaped support frame 211. The bottom of the rectangular mounting groove 311 extends through the U-shaped support frame 211. A rectangular sliding groove 312 is formed on the inner right side of the rectangular mounting groove 311. Two rectangular sliders 313 are slidably connected to the inner wall of the rectangular sliding groove 312. Two hinge blocks 314 are hinged inside the rectangular mounting groove 311.

The hydraulic cylinder 315 drives the two hinge blocks 314 to move away from each other under the limits of the two rectangular sliders 313, thereby causing the hinge rods 316 and 317 below to rotate. The two hinge rods 317 drive the sampling box 215 to descend through the support frame 214, thereby inserting the sampling box 215 into the soil below. Then, the hydraulic cylinder 315 is controlled to retract, thus driving the sampling box 215 through a similar transmission as described above. The sample box 215 rises, bringing out the soil sample. During discharge, hydraulic cylinder 2111 is activated to control its stretching. The output shaft of hydraulic cylinder 2111 drives the pressure plate 218 to descend. As the pressure plate 218 descends, it drives the circular slider 217 to slide within the spiral groove 216. Under the limit of the spiral groove 216, the circular slider 217 will make a circular motion around the central axis of the sampling box 215 while descending, thereby driving the pressure plate 218 to rotate. The pressure plate 218 drives several cleaning rods 219 below it to scrape the inner wall of the sampling box 215, thereby cleaning the inner wall of the sampling box 215 while discharging the soil sample.
