Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for soil detection in environmental protection projects. Background Art

[0002] The collection of soil samples constitutes the cornerstone of soil science research, geological exploration and environmental protection engineering, and provides the necessary material basis for the subsequent determination of soil physical and chemical properties. Especially in environmental protection engineering, accurate collection and analysis of soil samples is a key link in assessing the degree of soil pollution, formulating scientific remediation strategies and monitoring remediation results.

[0003] At present, most mainstream soil sampling devices rely on a driving mechanism to press the sampling tube into the soil, then lift the sampling tube and collect the soil sample. Although this method meets the sampling needs to a certain extent, it faces a severe challenge in actual operation: metal obstacles may be hidden in the soil. When the sampling tube collides with these metal obstacles during the process of being pressed into the soil, it is very easy to cause damage to the sampling tube, which in turn has an adverse effect on soil sampling. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a sampling device for soil detection in environmental protection engineering.

[0005] Technical solution: A sampling device for soil detection in environmental protection projects, including a base plate, walking wheels, a mounting frame and a handle. Four walking wheels are fixedly connected to the bottom of the base plate at intervals, and mounting frames are fixedly connected to the left and right sides of the top of the base plate. A handle is fixedly connected between the upper parts of the two mounting frames. It also includes a sampling component, a bulldozer component and a detection component. A sampling component for taking soil samples is jointly arranged between the two mounting frames and the base plate, a bulldozer component for pushing soil out of the sampling component is arranged between the tops of the two mounting frames, and a detection component for detecting whether there are metal obstacles in the soil is arranged on the top of the base plate.

[0006] Furthermore, the sampling assembly includes a screw, a reduction motor, a lifting plate and a sampling tube. A screw is rotatably connected between the upper parts of the two mounting frames and the bottom plate. A reduction motor is installed on the top of the two mounting frames. The output shaft ends of the two reduction motors are fixedly connected to the upper ends of the adjacent screws. A lifting plate is arranged between the two screws, and the two screws are threadedly matched with the lifting plate. A sampling tube is fixedly connected to the middle of the lifting plate.

[0007] Furthermore, the bulldozer assembly includes a crossbeam, an electric push rod and a circular push block. The crossbeam is fixedly connected between the tops of the two mounting frames, the electric push rod is installed in the middle of the crossbeam, and the circular push block is fixedly connected to the end of the telescopic rod of the electric push rod.

[0008] Furthermore, the detection component includes a sliding plate, a metal detector and a control box. Slide grooves are provided on the front and rear sides of the base plate. The two slide grooves are slidably connected to the sliding plates. The metal detector is fixedly connected between the two sliding plates. The control box is installed on the top rear side of the base plate, and the control box is electrically connected to the metal detector.

[0009] Furthermore, it also includes a fixed block, a guide rod, a ladder frame, a return spring and an inclined plate. The front and rear sides of the lower part of the left mounting frame are fixedly connected with fixed blocks, two guide rods are fixedly connected at intervals between the two fixed blocks, a ladder frame is slidably connected between the two guide rods, two return springs are connected between the front fixed block and the ladder frame, and an inclined plate is fixedly connected to the rear side of the lifting plate.

DETAILED DESCRIPTION

[0016] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] Embodiment: A sampling device for soil detection in environmental protection engineering, such as Figure 1-Figure 3 As shown, it includes a base plate 1, walking wheels 2, a mounting frame 21 and a handle 22. Four walking wheels 2 are welded and fixed at intervals on the bottom of the base plate 1. Mounting frames 21 are welded and fixed on the left and right sides of the top of the base plate 1. A handle 22 is welded and fixed between the upper parts of the two mounting frames 21. It also includes a sampling component, a bulldozer component and a detection component. A sampling component for taking soil samples is commonly arranged between the two mounting frames 21 and the base plate 1. A bulldozer component for pushing soil out of the sampling component is arranged between the tops of the two mounting frames 21. A detection component for detecting whether there are metal obstacles in the soil is arranged on the top of the base plate 1.

[0018] like Figure 1 and Figure 2 As shown, the sampling assembly includes a screw rod 31, a reduction motor 32, a lifting plate 33 and a sampling tube 34. The screw rod 31 is rotatably connected between the upper part of the two mounting frames 21 and the bottom plate 1. The reduction motor 32 is installed on the top of the two mounting frames 21 by bolts. The output shaft ends of the two reduction motors 32 are fixedly connected to the upper ends of the adjacent screw rods 31. A lifting plate 33 is arranged between the two screw rods 31, and the two screw rods 31 are threadedly matched with the lifting plate 33. The sampling tube 34 is fixed to the middle of the lifting plate 33 by bolts.

[0019] like Figure 1 and Figure 2 As shown, the bulldozer assembly includes a crossbeam 41, an electric push rod 42 and a circular push block 43. The crossbeam 41 is welded and fixed between the tops of the two mounting frames 21, the electric push rod 42 is installed on the middle of the crossbeam 41 by bolts, and the circular push block 43 is fixedly connected to the end of the telescopic rod of the electric push rod 42.

[0020] like Figure 2As shown, the detection component includes a sliding plate 52, a metal detector 53 and a control box 54. Slide grooves 51 are provided on the front and rear sides of the base plate 1. The two slide grooves 51 are slidably connected with the sliding plates 52. The metal detector 53 is fixed between the two sliding plates 52 by bolts. The control box 54 is installed on the top rear side of the base plate 1 by bolts. The control box 54 is electrically connected to the metal detector 53. The control box 54 has a built-in speaker. When the metal detector 53 detects a metal obstacle, the control box 54 will drive the speaker to sound, so that the staff can clearly hear the alarm sound.

[0021] When soil sampling is required, the staff first pushes the device to the sampling area, then starts the control box 54, and the metal detector 53 starts working. If there is a metal obstacle in the soil, the control box 54 will immediately sound an alarm, and the staff needs to continue pushing the device until the control box 54 stops sounding the alarm, thereby ensuring that there is no metal obstacle directly below the sampling tube 34, so as to ensure that the sampling tube 34 will not be damaged due to collision with the metal obstacle when inserted into the soil. After ensuring the safety of the sampling area, the staff slides the two sliding plates 52 to the rear side to move the metal detector 53 away from under the sampling tube 34, and then synchronously starts the two reduction motors 3 2. The two reduction motors 32 drive the two screw rods 31 to start rotating synchronously, thereby pushing the lifting plate 33 to move downward. As the lifting plate 33 descends, the sampling tube 34 is also smoothly inserted into the soil. After the sampling is completed, the two reduction motors 32 are controlled to reverse, driving the sampling tube 34 to reset upward. At this time, there is enough space between the sampling tube 34 and the ground, which is convenient for the staff to place soil collection items such as plastic bags under the sampling tube 34. Next, the electric push rod 42 is started, and the telescopic rod of the electric push rod 42 is extended to push the circular push block 43 to move downward along the inner wall of the sampling tube 34, pushing out the soil in the sampling tube 34, so that the staff can quickly collect soil samples.

[0022] like Figure 2 and Figure 3 As shown, it also includes a fixed block 61, a guide rod 62, a ladder frame 63, a return spring 64 and an inclined plate 65. The front and rear sides of the lower part of the left mounting frame 21 are welded and fixed with fixed blocks 61, two guide rods 62 are welded and fixed between the two fixed blocks 61 at intervals, and the ladder frame 63 is slidably connected between the two guide rods 62. Two return springs 64 are connected between the front fixed block 61 and the ladder frame 63, and the two return springs 64 are respectively sleeved on the outside of the two guide rods 62, and an inclined plate 65 is welded and fixed to the rear side of the lifting plate 33.

[0023] In the process of the lifting plate 33 driving the sampling tube 34 to move downward, the inclined plate 65 provided on the lifting plate 33 first contacts the ladder frame 63. As the inclined plate 65 continues to move downward, the ladder frame 63 is squeezed by the inclined plate 65, thereby moving backward along the guide rod 62, thereby driving the left sliding plate 52 to slide backward, so that the metal detector 53 is smoothly moved away from the bottom of the sampling tube 34. At this time, the return spring 64 is gradually stretched. In the process of the sampling tube 34 being inserted into the soil, the inclined plate 65 always maintains contact with the front side of the ladder frame 63. The metal detector 53 is in a fitted state, thereby ensuring that the ladder frame 63 will not move forward and reset due to the reset action of the reset spring 64, thereby avoiding unnecessary collision between the metal detector 53 and the sampling tube 34. When the lifting plate 33 moves upward and resets, the squeezing and limiting effect of the inclined plate 65 on the ladder frame 63 gradually disappears. Under the reset action of the reset spring 64, the ladder frame 63 drives the metal detector 53 to move back to the bottom of the sampling tube 34. In this way, the staff does not need to manually move the metal detector 53, which saves time and effort.

[0024] like Figure 2 As shown, an annular cutter head 7 is also included, and the annular cutter head 7 is welded and fixed to the bottom of the sampling tube 34.

[0025] The annular cutter head 7 is provided to facilitate the sampling tube 34 to break the soil, so that the sampling tube 34 can be inserted into the soil more smoothly.

[0026] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
