Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, in particular to a soil detection device for detecting deep soil. Background Art

[0002] Soil testing and sampling are important technical means for assessing soil environmental quality, understanding soil properties, and promoting sustainable soil management. The background of this technology is based on the following key points: Soil, as a core resource for agricultural production and a vital material foundation for human survival, is directly related to food security and ecological and environmental health. Therefore, regular and systematic soil testing is crucial. Soil testing aims to understand the extent and trends of soil pollution, as well as the current status of soil environmental quality, thereby providing a scientific basis for soil management and environmental protection. Sampling is a crucial step in the soil testing process. Sampling not only affects the accuracy of test results but also directly influences subsequent analysis, evaluation, and decision-making. To ensure scientific and representative sampling, strict technical specifications must be adhered to. First, appropriate monitoring sites should be identified based on monitoring objectives and requirements, combined with field survey results. These sites should comprehensively cover the different types of survey and monitoring units and represent the soil environmental quality within the area. Deep soil sampling requires drilling to a considerable depth. Currently, percussion drills are often used to drive the sampling tube deeper to complete the sampling task. However, due to the great depth of the deep soil, as the sampling tube continues to move downward, the contact area between its outer wall and the surrounding soil wall gradually increases, resulting in a continuous increase in friction, which in turn causes the sample collection rate to gradually slow down; for this reason, the present invention provides a soil detection device for deep soil detection. Summary of the Invention

[0003] The object of the present invention is to provide a soil detection device for detecting deep soil to solve the problems raised in the above background technology.

[0004] The technical solution of the present invention is: a soil detection equipment for deep soil detection, comprising a bottom plate, two electric push rods symmetrically fixedly installed on the top of the bottom plate, a top plate fixedly installed between the telescopic ends of the top of the two electric push rods, a quantitative rod welded to the bottom of the top plate, a quantitative plate welded to the bottom of the quantitative rod, a sampling tube rotatably connected to the bottom of the bottom plate, a plurality of internal air outlet holes are opened on the inner wall of the sampling tube, a plurality of external air outlet holes are opened on the outer wall of the sampling tube, an inner partition plate is welded to the bottom of the bottom plate, and the inner partition plate is located in the inner cavity of the sampling tube, a plurality of connecting slots are opened on the outer peripheral wall of the inner partition plate, a plurality of internal notches are opened on the inner wall of the inner partition plate, and a plurality of external notches are opened on the outer wall of the inner partition plate, the arranged electric push rod drives the top plate to move up, and the arranged top plate drives the quantitative rod and the quantitative plate to move up, and the depth of a single sampling is adjusted by adjusting the position of the quantitative plate.

[0005] Preferably, two mounting plates are welded to the bottom of the base plate, a motor is fixedly mounted on the side wall of one of the mounting plates, a worm is fixedly mounted on the output end of the motor, and the worm is rotatably connected between the two mounting plates, a worm wheel meshing with the worm is fixedly sleeved on the outer peripheral wall of the sampling tube, the motor drives the worm to rotate, the worm drives the worm wheel and the sampling tube to rotate, and the rotating sampling tube cooperates with the teeth at its bottom to facilitate sampling of soil with plant roots.

[0006] Preferably, an air pump is fixedly installed on one side of the bottom of the bottom plate, and a plurality of air inlet holes are opened on the outer peripheral wall of the sampling tube at equal intervals. An annular sealing plate is rotatably connected to the outer peripheral wall of the sampling tube, and the output end of the air pump is communicated with the annular sealing plate. The air pump inputs gas into the inner cavity of the sampling tube through the air inlet hole. Since the sampling tube rotates due to the operation of the motor, the inner partition remains stationary. It can be seen that the sampling tube and the inner partition perform relative rotation. In this process, when the inner notch is aligned with the inner air outlet, the gas input by the air pump passes through the inner notch in turn. The outer notch and the inner air outlet hole enter the soil sample inside the sampling tube, so as to loosen the soil sample to a certain extent, avoid the soil sample from being overly compacted during the sampling process, and thus improve the accuracy of the sampling amount; in addition, when the outer notch is aligned with the outer air outlet hole, the gas input by the air pump enters the gap between the outer wall of the sampling tube and the surrounding soil wall through the connecting slot hole, the outer notch and the outer air outlet hole in turn, and forms an air cavity in this gap, so that the friction between the outer wall of the sampling tube and the surrounding soil wall is small, thereby improving the sampling rate of the soil.

[0007] Preferably, a plurality of inner auxiliary air outlet holes and an annular air groove 1 are provided on the inner wall of the sampling tube, and the annular air groove 1 is connected to the plurality of inner auxiliary air outlet holes and the plurality of inner air outlet holes. A plurality of outer auxiliary air outlet holes and annular air groove 2 are provided on the outer wall of the sampling tube, and the annular air groove 2 is connected to the plurality of outer auxiliary air outlet holes and the plurality of outer air outlet holes. When the soil in the area of ​​the inner air outlet holes and the outer air outlet holes is too compact, the gas input by the air pump can enter the inner auxiliary air outlet holes through the annular air groove 1 or enter the outer auxiliary air outlet holes through the annular air groove 2, thereby enhancing the uniformity of gas outlet and ensuring smooth flow of the air path.

[0008] Preferably, a plurality of collecting grooves and a plurality of cleaning grooves are provided on the outer peripheral wall of the quantitative plate, and the plurality of collecting grooves and the plurality of cleaning grooves are connected. After the collecting grooves on the outer peripheral wall of the quantitative plate are aligned with the inner air outlet holes, the provided air pump and the motor are operated, and the gas input by the provided air pump is discharged through the cleaning groove, so as to clean the soil adhered to two adjacent teeth; in this way, since the motor drives the sampling tube to rotate, the sampling tube and the quantitative plate rotate relative to each other, so that the gas discharged from the cleaning groove can evenly clean the plurality of teeth arranged circumferentially.

[0009] Preferably, an annular frame is welded on the outer peripheral wall of the base plate, an impact drill is fixedly installed on the outer peripheral wall of the annular frame, and two symmetrical handles are welded on the side walls at both ends of the annular frame. When in use, the staff holds the handles on both sides of the annular frame with both hands, and then turns on the impact drill. The set impact drill drives the sampling tube to move downward to perform soil sampling operations.

[0010] Preferably, an annular slideway is welded to the bottom of the base plate, and an annular slider which is slidably arranged in a slide groove is welded to the outer peripheral wall of the sampling tube.

[0011] The present invention provides a soil detection device for deep soil detection through improvement. Compared with the prior art, it has the following improvements and advantages:

[0012] 1. The worm drives the worm gear and sampling tube to rotate. The rotating sampling tube cooperates with the teeth at its bottom to facilitate sampling of soil containing plant roots. In addition, the sampling tube and the inner partition rotate relative to each other, and the gas input by the air pump is intermittently and alternately input into the soil sample inside the sampling tube or into the gap between the outer wall of the sampling tube and the surrounding soil wall. This not only prevents the soil sample from being overly compacted during the sampling process, but also reduces the friction between the outer wall of the sampling tube and the surrounding soil wall.

[0013] 2. When the soil in the area of ​​the inner air outlet and the outer air outlet is too compact, the gas input by the air pump can enter the inner auxiliary air outlet through the annular air groove 1 or enter the outer auxiliary air outlet through the annular air groove 2, thereby enhancing the uniformity of gas outlet and ensuring the smooth flow of the gas path;

[0014] 3. The set quantitative plate can push out the soil sample to achieve the effect of automatic discharging; the downward moving quantitative plate can scrape off the soil sample adhering to the inner wall of the sampling tube; in addition, the set air pump can enter the soil sample near the bottom of the sampling tube through the internal air outlet to supply air. The soil sample near the bottom of the sampling tube is squeezed out of the sampling tube under the action of gas expansion, thereby assisting the quantitative plate in the discharging operation and thereby increasing the discharging speed;

[0015] 4. The gas input by the air pump is discharged through the cleaning groove to clean the soil adhering to the two adjacent teeth; because the motor drives the sampling tube to rotate, the sampling tube and the quantitative plate rotate relative to each other, so that the gas discharged from the cleaning groove can evenly clean several teeth arranged in a circle.

[0031] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] The present invention provides a soil detection device for deep soil detection through improvement. The technical solution of the present invention is:

[0033] like Figures 1-12As shown, a soil detection equipment for deep soil detection includes a bottom plate 1, an annular frame 26 is welded on the outer peripheral wall of the bottom plate 1, an impact drill 27 is fixedly installed on the outer peripheral wall of the annular frame 26, two symmetrical handles 28 are welded on the side walls at both ends of the annular frame 26, two electric push rods 2 are symmetrically fixedly installed on the top of the bottom plate 1, a top plate 3 is fixedly installed between the telescopic ends of the tops of the two electric push rods 2, a quantitative rod 4 is welded on the bottom of the top plate 3, a quantitative plate 5 is welded on the bottom of the quantitative rod 4, a sampling tube 6 is rotatably connected to the bottom of the bottom plate 1, an annular slide 29 is welded on the bottom of the bottom plate 1, and an annular slider 30 slidingly set in the slide groove is welded on the outer peripheral wall of the sampling tube 6. The staff controls the electric push rod 2 to move up through the controller integrated in the impact drill 27, and the set electric push rod 2 drives the top plate 3 to move up, and the set top plate 3 drives the quantitative The rod 4 and the quantitative plate 5 move upward, and the depth of a single sampling is adjusted by adjusting the position of the quantitative plate 5; when in use, the staff holds the handles 28 on both sides of the annular frame 26 with both hands, and then turns on the impact drill 27. The impact drill 27 drives the sampling tube 6 to move downward to perform soil sampling operations; two mounting plates 13 are welded to the bottom of the base plate 1, and a motor 14 is fixedly mounted on the side wall of one of the mounting plates 13. A worm 15 is fixedly mounted on the output end of the motor 14, and the worm 15 is rotatably connected between the two mounting plates 13. A worm gear 16 meshing with the worm 15 is fixedly sleeved on the outer peripheral wall of the sampling tube 6. The motor 14 drives the worm 15 to rotate, and the worm 15 drives the worm gear 16 and the sampling tube 6 to rotate. The rotating sampling tube 6 cooperates with the teeth at its bottom to facilitate sampling operations on soil with plant roots.

[0034] Furthermore, an air pump 17 is fixedly installed on one side of the bottom of the bottom plate 1, and a number of air inlet holes 18 are opened on the outer peripheral wall of the sampling tube 6 at equal intervals. An annular sealing plate 19 is rotatably connected to the outer peripheral wall of the sampling tube 6. The output end of the air pump 17 is connected to the annular sealing plate 19, and a number of internal air outlet holes 7 are opened on the inner wall of the sampling tube 6. A number of external air holes 8 are opened on the outer wall of the sampling tube 6. An inner partition 9 is welded to the bottom of the bottom plate 1, and the inner partition 9 is located in the inner cavity of the sampling tube 6. A number of connecting slots 10 are opened on the outer peripheral wall of the inner partition 9, a number of inner notches 11 are opened on the inner wall of the inner partition 9, and a number of outer notches 12 are opened on the outer wall of the inner partition 9. The air pump 17 inputs gas into the inner cavity of the sampling tube 6 through the air inlet hole 18. Since the sampling tube 6 rotates under the operation of the motor 14, the inner partition provided 9 remains stationary. It can be seen that the sampling tube 6 and the inner partition 9 perform relative rotational motion. During this process, when the inner notch 11 is aligned with the inner air outlet 7, the gas input by the air pump 17 enters the soil sample inside the sampling tube 6 through the inner notch 11 and the inner air outlet 7 in turn, thereby loosening the soil sample to a certain extent, avoiding the soil sample from being overly compacted during the sampling process, and thus improving the accuracy of the sampling amount; in addition, when the outer notch 12 is aligned with the outgoing air hole 8, the gas input by the air pump 17 enters the gap between the outer wall of the sampling tube 6 and the surrounding soil wall through the connecting slot 10, the outer notch 12 and the outgoing air hole 8 in turn, and forms an air cavity in this gap, so that the friction between the outer wall of the sampling tube 6 and the surrounding soil wall is small, thereby improving the sampling rate of the soil.

[0035] Furthermore, a plurality of inner auxiliary air outlet holes 20 and annular air groove 1 21 are provided on the inner wall of the sampling tube 6, and the annular air groove 1 21 is connected to the plurality of inner auxiliary air outlet holes 20 and the plurality of inner air outlet holes 7. A plurality of outer auxiliary air outlet holes 22 and annular air groove 2 23 are provided on the outer wall of the sampling tube 6, and the annular air groove 2 23 is connected to the plurality of outer auxiliary air outlet holes 22 and the plurality of outer air outlet holes 8. When the soil in the area of ​​the inner air outlet holes 7 and the outer air outlet holes 8 is too compact, the gas input by the air pump 17 can enter the inner auxiliary air outlet holes 20 through the annular air groove 1 21 or enter the outer auxiliary air outlet holes 22 through the annular air groove 23, thereby enhancing the uniformity of gas outlet and ensuring the smooth flow of the gas path.

[0036] Furthermore, a plurality of collecting grooves 24 and a plurality of cleaning grooves 25 are provided on the outer peripheral wall of the quantitative plate 5, and the plurality of collecting grooves 24 and the plurality of cleaning grooves 25 are connected. After the collecting grooves 24 on the outer peripheral wall of the quantitative plate 5 are aligned with the inner air outlet 7, the set air pump 17 and the motor 14 are operated, and the gas input by the set air pump 17 is discharged through the cleaning groove 25, so as to clean the soil adhered to two adjacent teeth; thus, since the motor 14 drives the sampling tube 6 to rotate, the sampling tube 6 and the quantitative plate 5 rotate relative to each other, so that the gas discharged from the cleaning groove 25 can evenly clean the plurality of teeth arranged circumferentially.

[0037] Working principle: Before use, the staff can adjust the depth of a single sampling according to the actual sampling needs; first, the staff controls the electric push rod 2 to move upward through the controller integrated in the impact drill 27, and the set electric push rod 2 drives the top plate 3 to move upward, and the set top plate 3 drives the quantitative rod 4 and the quantitative plate 5 to move upward. The depth of a single sampling is adjusted by adjusting the position of the quantitative plate 5;

[0038] When in use, the staff holds the handles 28 on both sides of the annular frame 26 with both hands, and then turns on the impact drill 27. The impact drill 27 drives the sampling tube 6 to move down to perform soil sampling operations; it should be noted that there is a constant pressure air hole 31 between the upper and lower ends of the quantitative plate 5 to ensure that the internal air pressure of the sampling tube 6 is stable; at the same time, the motor 14 and the air pump 17 are in operation, and the motor 14 drives the worm 15 to rotate, and the worm 15 drives the worm gear 16 and the sampling tube 6 to rotate. The rotating sampling tube 6 cooperates with the teeth at its bottom to facilitate the sampling operation of the soil with plant roots; at the same time, the air pump 17 inputs gas into the inner cavity of the sampling tube 6 through the air inlet 18. Since the sampling tube 6 rotates due to the operation of the motor 14, the inner partition 9 remains stationary. It can be seen that the sampling tube 6 and the inner partition 9 perform relative rotation. In this process, when the inner notch 11 is aligned with the inner air outlet 7, the air pump 1 The gas input by the air pump 17 enters the soil sample inside the sampling tube 6 through the inner notch 11 and the inner air outlet 7 in turn, thereby loosening the soil sample to a certain extent, avoiding the soil sample from being overly compacted during the sampling process, and thus improving the accuracy of the sampling amount; in addition, when the outer notch 12 is aligned with the outgoing air hole 8, the gas input by the air pump 17 enters the gap between the outer wall of the sampling tube 6 and the surrounding soil wall through the connecting slot 10, the outer notch 12 and the outgoing air hole 8 in turn, and forms an air cavity in this gap, so that the friction between the outer wall of the sampling tube 6 and the surrounding soil wall is small, thereby improving the sampling rate of the soil; among them, when the soil in the area of ​​the inner air outlet 7 and the outgoing air hole 8 is too compact, the gas input by the air pump 17 can enter the inner auxiliary air outlet 20 through the annular air groove 1 21 or enter the outer auxiliary air outlet 22 through the annular air groove 23, thereby enhancing the uniformity of the gas outlet, thereby ensuring the smooth flow of the gas path;

[0039] After the sampling is completed, the electric push rod 2 drives the top plate 3, the quantitative rod 4 and the quantitative plate 5 to move downward, and the quantitative plate 5 can push out the soil sample collected in the sampling tube 6 to achieve the effect of automatic discharging; at the same time, the downward-moving quantitative plate 5 can scrape off the soil sample adhered to the inner wall of the sampling tube 6 to prevent the residual soil sample from being mixed into the next sampling process; in addition, during the discharging process, the air pump 17 can enter the soil sample near the bottom of the sampling tube 6 through the inner air outlet 7 to supply air, and the soil sample near the bottom of the sampling tube 6 is squeezed out of the sampling tube 6 under the action of gas expansion, so as to This is to assist the quantitative plate 5 in the discharging operation, thereby increasing the discharging speed; after the collecting groove 24 on the outer wall of the quantitative plate 5 is aligned with the internal air outlet 7, the set air pump 17 and the motor 14 are operated, and the gas input by the set air pump 17 is discharged through the cleaning groove 25, so as to clean the soil adhering to the two adjacent teeth; in addition, since the motor 14 drives the sampling tube 6 to rotate, the sampling tube 6 and the quantitative plate 5 rotate relative to each other, so that the gas discharged from the cleaning groove 25 can evenly clean several teeth arranged circumferentially, which reduces the difficulty of manual cleaning to a certain extent.
