DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The present application embodiment discloses a soil sample collection device for soil pollution detection. Figure 1-4 A soil sample collection device for soil pollution detection includes a bracket 1, the bracket 1 is liftable and provided with a sampling tube 2, the sampling tube 2 is provided with a screw 3, the sampling tube 2 is provided with a driving component 4 for driving the screw 3 to move, a drill rod 5 is fixed to the bottom end of the screw 3, a spiral blade 6 is sleeved on the outer wall of the drill rod 5, a connecting plate 7 located above the spiral blade 6 is sleeved on the outer wall of the drill rod 5, a scraper 8 is provided at the bottom end of the connecting plate 7 for contacting with the sampling tube 2, and the scraper 8 is connected to the connecting plate 7 through an elastic component 9.

[0028] In this embodiment, when sampling the soil, the bracket 1 is placed at the sampling position, and a pedal is provided at the bottom of the bracket 1. When sampling, the personnel step on the pedal to improve the stability of the bracket 1, and then the sampling tube 2 is extended into the soil, and then the screw 3 is driven to move downward under the movement of the driving component 4, and the screw 3 drives the drill rod 5 and the spiral blade 6 to move downward and extend into the soil, and the soil can be collected by the spiral blade 6, and then under the reverse movement of the driving component 4, the screw 3 is driven to move upward, thereby driving the drill rod 5 and the spiral blade 6 to move upward, and the soil can be collected into the sampling tube 2, and then the sampling tube 2 is moved upward to extract the soil from the sampling tube 2, and the soil sampling can be completed. Then, when the soil needs to be discharged from the sampling tube 2, the driving component 4 drives the screw 3 to move downward again to discharge the soil. At the same time, with the cooperation of the elastic component 9 and the scraper 8, the inner wall of the sampling tube 2 can be scraped and cleaned to reduce soil residue, thereby facilitating soil detection and improving the accuracy of soil detection.

[0029] In a further embodiment, Figure 2-3 As shown, the driving assembly 4 includes a driving motor 41 fixedly arranged on the top of the inner wall of the sampling tube 2, the output shaft of the driving motor 41 is fixed with a telescopic rod 42 fixed to the screw 3, the inner wall of the sampling tube 2 is fixed with a support plate 43 threadedly connected to the screw 3, the elastic assembly 9 includes a vertical plate 91 fixedly arranged on the bottom end of the connecting plate 7, the vertical plate 91 is interspersed with a through plate 92 fixed to the scraper 8, and a through groove 93 for the through plate 92 to be inserted is opened on one side of the vertical plate 91, and the through groove 93 is fixedly connected to the through plate 92 through a spring 94.

[0030] When the sampling tube 2 is extended into the soil, the telescopic rod 42 is driven to rotate under the movement of the driving motor 41, and the telescopic rod 42 drives the screw 3 to rotate. At the same time, since the screw 3 is threadedly connected to the support plate 43 and the telescopic cooperation of the telescopic rod 42, the screw 3 can be driven to move downward, so that the screw 3 moves downward while rotating, that is, the drill rod 5 and the spiral blade 6 are driven to move synchronously, so that the drill rod 5 and the spiral blade 6 are extended into the soil to sample the soil. Then, under the reverse movement of the driving motor 41, the drill rod 5 and the spiral blade 6 can be driven to rotate in the opposite direction and move upward at the same time, so that the soil is collected in the sampling tube 2, and the soil sampling is completed. The sample tube 2 is separated from the soil. When the soil needs to be discharged from the sampling tube 2, the driving motor 41 moves again, driving the screw 3 to move downward again, and the screw 3 drives the drill rod 5 and the spiral blade 6 to move downward again, so that the soil in the sampling tube 2 can be discharged. At the same time, when the screw 3 moves downward and rotates, it drives the scraper 8 to spirally descend, and under the elastic action of the spring 94, it drives the penetration plate 92 to move. The penetration plate 92 drives the scraper 8 to fully contact the inner wall of the sampling tube 2, and the inner wall of the sampling tube 2 can be scraped and cleaned under the spiral descent of the scraper 8, reducing the residual soil on the inner wall of the sampling tube 2, thereby facilitating soil detection and improving the accuracy of soil detection.

[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, a slide plate 10 fixed to the sampling tube 2 is slidably provided at the bottom end of the bracket 1, an electric telescopic rod 11 fixed to the slide plate 10 is fixed at the bottom end of the bracket 1, the slide plate 10 is connected to the bracket 1 through a sliding component 12, and a measuring component 13 for measuring the slide plate 10 is provided on one side of the bracket 1.

[0032] When the bracket 1 is placed at the sampling position, the electric telescopic rod 11 moves, driving the slide plate 10 to move downward, and the slide plate 10 drives the sampling tube 2 to move downward, so that the sampling tube 2 extends into the soil. At the same time, with the cooperation of the measuring component 13, the insertion depth of the sampling tube 2 can be measured, thereby facilitating sampling of soil at different depths and improving the sampling efficiency of the soil.

[0033] In a further embodiment, Figure 4 As shown, the sliding assembly 12 includes sliders 121 fixedly arranged on both sides of the slide plate 10, and both sides of the bracket 1 are provided with sliding grooves 122 for the sliders 121 to slide. The measuring assembly 13 includes a measuring ruler 131 fixedly arranged on one side of the bracket 1, and a pointer 132 corresponding to the measuring ruler 131 is fixed on one side of the slide plate 10.

[0034] When the electric telescopic rod 11 drives the slide plate 10 to move downward, with the cooperation of the slider 121 and the slide groove 122, the movement of the slide plate 10 is kept stable, and the slide plate 10 drives the sampling tube 2 to move downward and extend into the soil. During the movement of the slide plate 10, the pointer 132 is also driven to move, so that the pointer 132 indicates on the measuring ruler 131, and the movement distance of the slide plate 10 can be measured, thereby measuring the insertion depth of the sampling tube 2, which is convenient for soil sampling. When the bottom of the sampling tube 2 and the bottom of the bracket 1 are on the same horizontal line, the pointer 132 is located at the zero scale of the measuring ruler 131. Therefore, when the slide plate 10 drives the sampling tube 2 to move downward and extend into the soil, the pointer 132 also starts to move from the zero scale of the measuring ruler 131, so that the insertion depth of the sampling tube 2 is consistent with the scale indicated by the pointer 132, thereby facilitating the measurement of the insertion depth of the sampling tube 2.

[0035] The implementation principle of a soil sample collection device for soil pollution detection in the embodiment of the present application is as follows: first, the bracket 1 is placed at the sampling position, and then the slide plate 10 is driven to move downward under the movement of the electric telescopic rod 11, and the slide plate 10 drives the sampling tube 2 to move downward, so that the sampling tube 2 extends into the soil, and then the telescopic rod 42 is driven to rotate under the movement of the driving motor 41, and the telescopic rod 42 drives the screw 3 to rotate. At the same time, under the thread cooperation of the support plate 43, the screw 3 can be driven to rotate and move downward, and the screw 3 drives the drill rod 5 and the spiral blade 6 to move synchronously, so that the drill rod 5 and the spiral blade 6 can be extended into the soil, and then under the reverse movement of the driving motor 41, the soil can be collected into the sampling tube 2 through the drill rod 5 and the spiral blade 6. When the soil needs to be collected, When the soil is discharged for detection, when the screw 3 drives the drill rod 5 and the spiral blade 6 to move downward again to discharge the soil, the scraper 8 is driven to spirally descend, and at the same time, under the elastic action of the spring 94, the penetration plate 92 is driven to move, and the penetration plate 92 drives the scraper 8 to contact the inner wall of the sampling tube 2, and the scraper 8 can be used to scrape and clean the inner wall of the sampling tube 2, thereby reducing soil residue, facilitating soil detection, and improving the accuracy of soil detection. In the process of the slide plate 10 driving the sampling tube 2 to extend into the soil, the slide plate 10 drives the pointer 132 to move synchronously, so that the pointer 132 indicates on the measuring ruler 131, and the insertion depth of the sampling tube 2 can be measured, thereby facilitating the sampling of soil at different depths and improving the soil sampling efficiency.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
