Description

Technical Field

[0001] The invention relates to the technical field of soil sampling equipment, in particular to a deep soil sampling device for ecological restoration and a use method thereof. Background Art

[0002] Ecological restoration is a comprehensive method of repairing polluted environment under the guidance of ecological principles, based on biological restoration, combined with various physical restoration, chemical restoration and engineering technical measures, through optimized combination to achieve the best effect and lowest cost. When soil or water is contaminated by heavy metals, plants will absorb heavy metals from the rhizosphere to varying degrees. The amount absorbed is affected by factors such as the physiological function of plant roots, the composition of microbial communities in the rhizosphere, pH value, oxidation-reduction potential, the type and concentration of heavy metals, and the physical and chemical properties of the soil. Therefore, in the early preparation process of ecological restoration, it is very necessary to sample and investigate the soil in the restoration area.

[0003] Among them, when sampling deep soil, it is necessary to dig the soil through a drill barrel so that the sampled samples remain on the inner wall of the drill barrel. In this process, as the drill barrel goes deeper, the shallow soil samples will gradually move upward along the inner wall of the drill barrel. In this process, various factors in the shallow samples will stick to the inner wall of the drill barrel and come into contact with the subsequent deep soil, contaminating the deep soil samples. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a deep soil sampling device for ecological restoration, comprising a frame, an electric telescopic rod is fixedly connected to the top of the frame, an end of the electric telescopic rod away from the frame is fixedly connected to a mounting plate, a slide rail is fixedly connected to the top of the frame, a numerical control motor is fixedly connected to the bottom of the mounting plate, a sliding bracket is slidably connected to the inner wall of the slide rail, a rolling column is fixedly connected to the output end of the numerical control motor, and the outer wall of the rolling column is rotatably connected to the inner wall of the sliding bracket;

[0005] The driving mechanism includes a gear fixedly connected to the outer wall of the numerical control motor, a gear ring is rotatably connected to the top of the sliding bracket, a drill tube is fixedly connected to the inner wall of the gear ring, and a receiving tube is fixedly connected to the inner wall of the drill tube;

[0006] The drill mechanism includes a plurality of hydraulic grooves provided on the inner wall of the accommodating tube, a rotating column is rotatably connected to the bottom of the drill tube, an arc panel is fixedly connected to the outer wall of the rotating column, an inclined contact blade is fixedly connected to the outer wall of the arc panel, an outflow groove is provided on the outer wall of the inclined contact blade, a mounting triangle plate is fixedly connected to the inner wall of the arc panel, an elastic baffle is fixedly connected to the top of the mounting triangle plate, and a control component is fixedly connected to the top of the mounting triangle plate. In order to solve the problem that shallow soil will cause pollution to deep soil samples during sampling, a drill mechanism is arranged inside the equipment. Before use, push the frame to the required position, align the drill mechanism with the drilling position, turn on the power of the CNC motor and the electric telescopic rod, and the electric telescopic rod will shrink to force the deep soil sample to be contaminated. The mounting plate is moved downward, and the mounting plate will drive the CNC motor to move downward synchronously. The CNC motor drives the gear ring and the drill tube to rotate clockwise through the gears. When the drill tube rotates clockwise, the inclined contact blade and the arc panel will first contact the soil surface. Under the influence of the clockwise rotation, multiple arc panels will move closer to the center of the drill tube, so that the multiple arc panels form a cone shape, which prevents shallow soil from entering the receiving tube during the early drilling process and prevents shallow soil from affecting the sample accuracy of deep soil. When the drill bit mechanism reaches the required position, the CNC motor rotates counterclockwise. At this time, the edge of the inclined contact blade will contact the soil and force the soil to pass through the outflow trough, so that the arc panel and the inclined contact blade rotate outward with the rotating column as the center of gravity, presenting a Figure 6 In the state shown, as the electric telescopic rod continues to contract, the deep soil will enter the containing tube, and after taking enough samples, the CNC motor will rotate clockwise again to close the multiple arc panels and the inclined contact blades, and then the electric telescopic rod will extend to complete the sampling of the sample. Through the application of the above components, the equipment can avoid the contamination of the sample by the shallow soil during the sampling process.

[0007] Preferably, the control assembly includes a rotating rod rotatably connected to the top of the mounting triangle plate, and one end of the rotating rod away from the mounting triangle plate is rotatably connected to a piston block 1, and the outer wall of the piston block 1 is slidably connected to the inner wall of the hydraulic groove.

[0008] Preferably, the control assembly further comprises a piston block 2 slidably connected to the inner wall of the hydraulic groove, a fixing column is fixedly connected to the top of the piston block 2, and a fixing ring is fixedly connected to the top of a plurality of fixing columns.

[0009] Preferably, the control component also includes a spring 1 fixedly connected to the top of the fixing ring, and the end of the spring 1 away from the fixing ring is fixedly connected to a fixing plate, and the outer wall of the fixing plate is slidably connected to the inner wall of the drill tube. When the drill tube rotates counterclockwise, the arc panel will rotate downward with the rotating column as the center. A control component is arranged inside the equipment, and when the arc panel rotates, the arc panel drives the installation triangle plate to rotate downward synchronously, and the installation triangle plate drives the piston block 1 to move downward along the inner wall of the hydraulic groove through the rotating rod. At this time, the piston block moves down through the top liquid to drive the piston block 2 and the fixed column to move downward synchronously. When multiple fixed columns move downward, they will drive the fixing ring to move downward synchronously. In this process, the fixing ring will control the speed and length of the downward movement of multiple fixed columns and the piston block 2, and indirectly control the outward rotation angle of the multiple arc panels, so that the outward expansion angles of the multiple arc panels are equal, thereby avoiding different outward expansion rates of the arc panels, causing the sample soil to be crushed, and affecting the detection accuracy of the sample.

[0010] Preferably, the outer wall of the gear is meshed with the outer wall of the gear ring, a pushing assembly is slidably connected at the inner wall of the fixed plate, the outer wall of the slide rail is slidably connected to the inner wall of the through hole of the mounting plate, the top of the CNC motor is fixedly connected to the bottom of the mounting plate, and the above-mentioned fixing ring is used to control the length of the downward movement of multiple fixed columns. A spring 1 and a fixing plate are arranged inside the equipment. When the drill bit mechanism is unfolding outward, if one of the arc panels is blocked during outward expansion, the corresponding piston block 2 will be difficult to slide downward along the inner wall of the hydraulic groove. At this time, the blocked piston block 2 limits the downward movement of the fixing ring through the fixing column, and the obstruction of the fixing ring will limit the downward movement of the remaining piston blocks 2. In this process, the unobstructed multiple piston blocks 2 are still affected by the bottom arc panel and generate pulling force downward. The pulling force generated by the downward movement of the multiple unobstructed piston blocks 2 will be transmitted to the fixing ring through the corresponding fixing column, so that the fixing ring pushes the blocked fixed column and the piston block 2 to move downward. Through the application of the above-mentioned components, it is possible to avoid obstruction of a single arc panel and affect the outward expansion efficiency of the drill bit mechanism.

[0011] Preferably, the ejection assembly includes a sliding rod slidably connected to the inner wall of the fixed plate, the top of the fixed plate is fixedly connected to a fixed frame, the inner wall of the fixed frame is rotatably connected to a toothed roller, the bottom of the fixed plate is fixedly connected to a spring 2, and one end of the spring 2 away from the fixed plate is fixedly connected to the top of the fixed ring.

[0012] Preferably, the ejection assembly also includes a limit spring piece fixedly connected to the limit spring piece, the other end of the limit spring piece is fixedly connected to the limit spring block, the outer wall of the limit spring block contacts the outer wall of the toothed roller, and the bottom of the sliding rod is fixedly connected with a ejection plate. After the sampling is completed, as the electric telescopic rod is extended, the drill barrel will drive the sample to move upward. At this time, the staff pushes the sliding rod to force the sliding rod to move downward. At this time, the outer wall of the sliding rod contacts the outer wall of the toothed roller, and the toothed roller is in a stopped state due to the limit of the limit spring piece and the ejection plate, and the friction between the toothed roller and the sliding rod will drive the fixed frame and the fixed plate along the inner wall of the drill barrel When sliding downward, the fixed plate moves downward, and the distance between the fixed plate and the fixed ring is reduced. When the pressure of spring 2 exceeds that of the fixed plate, the downward force of the fixed plate will drive the fixed ring to move downward through spring 2. The downward movement of the fixed ring forces the bottom arc panel to open outward, and as the sliding rod continues to move downward, the thrust generated by the sliding rod will exceed the limit of the toothed roller and the limiting spring block, causing the limiting spring piece to rotate. The downward movement of the sliding rod will drive the push-out plate to move downward along the inner wall of the containing tube, pushing the sample inside the containing tube outward. Through the application of the above components, the sample soil can be prevented from becoming loose during discharge, thereby affecting the detection accuracy.

[0013] A method for using a deep soil sampling device for ecological restoration comprises the following steps:

[0014] S1: Push the device to determine the position;

[0015] S2: Turn on the power;

[0016] S3: Push out the sample.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention aims to solve the problem that shallow soil may contaminate deep soil samples during sampling. A drill mechanism is provided inside the device. Before use, the frame is pushed to the desired position, the drill mechanism is aligned with the drilling position, and the power of the CNC motor and the electric telescopic rod is turned on. At this time, the electric telescopic rod contracts, forcing the mounting plate to move downward. At this time, the mounting plate will drive the CNC motor to move downward synchronously, and the CNC motor drives the gear ring and the drill barrel to rotate clockwise through the gear. When the drill barrel rotates clockwise, the inclined contact blade and the arc plate will first contact the soil surface. Under the influence of the clockwise rotation, the multiple arc plates will move closer to the center of the drill barrel, so that the multiple arc plates form a cone shape, so as to prevent the shallow soil from entering the containing tube during the early drilling, and to prevent the shallow soil from affecting the sample accuracy of the deep soil. When the drill mechanism reaches the desired position, the CNC motor rotates counterclockwise. At this time, the cutting edge of the inclined contact blade will contact the soil and force the soil to pass through the inside of the outflow trough, so that the arc plate and the inclined contact blade rotate outward with the rotating column as the center of gravity, presenting as follows Figure 6In the state shown, as the electric telescopic rod continues to contract, the deep soil will enter the containing tube, and after taking enough samples, the CNC motor will rotate clockwise again to close the multiple arc panels and the inclined contact blades, and then the electric telescopic rod will extend to complete the sampling of the sample. Through the application of the above components, the equipment can avoid the contamination of the sample by the shallow soil during the sampling process.

[0019] (2) The present invention utilizes the characteristic that when the drill tube rotates counterclockwise, the arc panel will rotate downward with the rotating column as the center. A control component is arranged inside the device. When the arc panel rotates, the arc panel drives the installation triangle plate to rotate downward synchronously, and the installation triangle plate drives the piston block 1 to move downward along the inner wall of the hydraulic groove through the rotating rod. At this time, the piston block moves downward through the top liquid to drive the piston block 2 and the fixed column to move downward synchronously. When multiple fixed columns move downward, they will drive the fixed ring to move downward synchronously. In this process, the fixed ring will control the speed and length of the multiple fixed columns and the downward movement of the piston block 2, and indirectly control the outward rotation angles of the multiple arc panels, so that the outward expansion angles of the multiple arc panels are equal, thereby avoiding the different outward expansion rates of the arc panels, which will cause the sample soil to be crushed and affect the detection accuracy of the sample.

[0020] (3) The present invention utilizes the above-mentioned fixed ring to control the length of multiple fixed columns moving downward. A spring 1 and a fixed plate are arranged inside the equipment. When the drill bit mechanism is unfolding outward, if one of the arc panels is blocked during outward extension, the corresponding piston block 2 will have difficulty sliding downward along the inner wall of the hydraulic groove. At this time, the blocked piston block 2 limits the downward movement of the fixed ring through the fixed column, and the obstruction of the fixed ring will limit the downward movement of the remaining piston blocks 2. During this process, the multiple unobstructed piston blocks 2 are still affected by the bottom arc panel and generate a pulling force downward. The pulling force generated by the multiple unobstructed piston blocks 2 during downward movement will be transmitted to the fixed ring through the corresponding fixed column, so that the fixed ring pushes the blocked fixed column and the piston block 2 to move downward. Through the application of the above-mentioned components, it is possible to avoid obstruction of a single arc panel and affect the outward extension efficiency of the drill bit mechanism.

[0021] (4) After the sampling is completed, the drill tube will drive the sample to move upward as the electric telescopic rod is extended. At this time, the staff will push the sliding rod to force the sliding rod to move downward. At this time, the outer wall of the sliding rod contacts the outer wall of the toothed roller, and the toothed roller is in a stopped state due to the limiting spring piece and the push-out plate. The friction between the toothed roller and the sliding rod will drive the fixed frame and the fixed plate to slide downward along the inner wall of the drill tube. When the fixed plate moves downward, the distance between the fixed plate and the fixed ring is reduced. When the pressure of the spring 2 exceeds the excessive pressure, the downward force of the fixed plate will drive the fixed ring to move downward through the spring 2. The downward movement of the fixed ring forces the bottom arc panel to open outward. As the sliding rod continues to move downward, the thrust generated by the sliding rod will exceed the limit of the toothed roller and the limiting spring block, causing the limiting spring piece to rotate. The downward movement of the sliding rod will drive the push-out plate to move downward along the inner wall of the containing tube, pushing the sample inside the containing tube outward. Through the application of the above components, the sample soil is prevented from becoming loose during discharge, thereby affecting the detection accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The driving mechanism 2 includes a gear 21 fixedly connected to the outer wall of the numerical control motor 14, a gear ring 22 is rotatably connected to the top of the sliding bracket 15, a drill tube 23 is fixedly connected to the inner wall of the gear ring 22, and a receiving tube 24 is fixedly connected to the inner wall of the drill tube 23;

[0039] The drill mechanism 3 includes a plurality of hydraulic grooves 31 provided on the inner wall of the accommodating tube 24, a rotating column 32 is rotatably connected to the bottom of the drill tube 23, an arc panel 33 is fixedly connected to the outer wall of the rotating column 32, an inclined contact blade 34 is fixedly connected to the outer wall of the arc panel 33, an outflow groove 37 is provided on the outer wall of the inclined contact blade 34, a mounting triangle plate 35 is fixedly connected to the inner wall of the arc panel 33, an elastic baffle 36 is fixedly connected to the top of the mounting triangle plate 35, and a control component 4 is fixedly connected to the top of the mounting triangle plate 35. In order to solve the problem that shallow soil will cause pollution to deep soil samples during sampling, a drill mechanism 3 is arranged inside the equipment. Before use, push the frame 1 to the desired position, align the drill mechanism 3 with the drilling position, turn on the power of the CNC motor 14 and the electric telescopic rod 11, and the electric telescopic rod 11 will shrink. The mounting plate 12 is forced to move downward, at which time the mounting plate 12 will drive the CNC motor 14 to move downward synchronously, and the CNC motor 14 drives the gear ring 22 and the drill tube 23 to rotate clockwise through the gear 21. When the drill tube 23 rotates clockwise, the inclined contact blade 34 and the arc panel 33 will first contact the soil surface. Under the influence of the clockwise rotation, the multiple arc panels 33 will move closer to the center of the drill tube 23, so that the multiple arc panels 33 form a cone shape, so as to avoid the shallow soil from entering the receiving tube 24 during the early drilling, so as to avoid the shallow soil from affecting the sample accuracy of the deep soil; when the drill bit mechanism 3 reaches the desired position, the CNC motor 14 rotates counterclockwise, at which time the cutting edge of the inclined contact blade 34 will contact the soil and force the soil to pass through the outflow groove 37, so that the arc panel 33 and the inclined contact blade 34 rotate outward with the rotating column 32 as the center of gravity, presenting as shown in the figure. Figure 6 In the state shown, as the electric telescopic rod 11 continues to contract, the deep soil will enter the containing tube 24, and after taking enough samples, the CNC motor 14 will rotate clockwise again to close the multiple arc panels 33 and the inclined contact blades 34, and then the electric telescopic rod 11 will extend to complete the sampling of the sample. Through the application of the above components, the equipment can avoid contamination of the sample by the shallow soil during the sampling process.

[0040] For example 2, please refer to Figure 7 - Fig.11 The present invention is a deep soil sampling device for ecological restoration. On the basis of embodiment one, the control component 4 includes a rotating rod 41 rotatably connected to the top of the mounting triangle plate 35, and the end of the rotating rod 41 away from the mounting triangle plate 35 is rotatably connected to a piston block 42, and the outer wall of the piston block 42 is slidably connected to the inner wall of the hydraulic groove 31.

[0041] The control assembly 4 further comprises a second piston block 43 slidably connected to the inner wall of the hydraulic groove 31 , a fixing column 44 is fixedly connected to the top of the second piston block 43 , and a fixing ring 45 is fixedly connected to the top of a plurality of fixing columns 44 .

[0042] The control assembly 4 also includes a spring 46 fixedly connected to the top of the fixing ring 45, and one end of the spring 46 away from the fixing ring 45 is fixedly connected to a fixing plate 47, and the outer wall of the fixing plate 47 is slidably connected to the inner wall of the drill tube 23. When the drill tube 23 rotates counterclockwise, the arc panel 33 will rotate downward with the rotating column 32 as the center. The control assembly 4 is arranged inside the device. When the arc panel 33 rotates, the arc panel 33 drives the installation triangle plate 35 to rotate downward synchronously, and the installation triangle plate 35 drives the piston block 42 along the rotating rod 41. As the inner wall of the hydraulic groove 31 moves downward, the piston block 1 42 moves downward and drives the piston block 2 43 and the fixed column 44 to move downward synchronously through the top liquid. When multiple fixed columns 44 move downward, they will drive the fixed ring 45 to move downward synchronously. In this process, the fixed ring 45 will control the speed and length of the multiple fixed columns 44 and the piston block 2 43 to move downward, and indirectly control the outward rotation angle of the multiple arc panels 33, so that the outward expansion angles of the multiple arc panels 33 are equal, avoiding different expansion rates of the arc panels 33, causing the sample soil to be crushed, and affecting the detection accuracy of the sample.

[0043] The outer wall of the gear 21 is meshed with the outer wall of the gear ring 22, the inner wall of the fixed plate 47 is slidably connected with the ejection assembly 5, the outer wall of the slide rail 13 is slidably connected with the inner wall of the through hole of the mounting plate 12, the top of the numerical control motor 14 is fixedly connected with the bottom of the mounting plate 12, and the above-mentioned fixing ring 45 is used to control the length of the multiple fixing columns 44 moving downward. A spring 1 46 and a fixing plate 47 are arranged inside the device. When the drill mechanism 3 is unfolding outward, if one of the arc panels 33 is blocked when unfolding, the corresponding piston block 2 43 will be difficult to slide downward along the inner wall of the hydraulic groove 31. At this time, the blocked piston block 2 43 limits the downward movement of the fixing ring 45 through the fixing column 44, and the blocking of the fixing ring 45 will limit the downward movement of the remaining piston blocks 2 43. In this process, the unblocked multiple piston blocks 2 43 are still affected by the bottom arc panel 33 to generate pulling force downward. The pulling force generated by the downward movement of the multiple unblocked piston blocks 2 43 will be transmitted to the fixing ring 45 through the corresponding fixing column 44, so that the fixing ring 45 pushes the blocked fixing column 44 and the piston block 2 43 to move downward. Through the application of the above components, it is possible to avoid obstruction of a single arc panel 33 and affect the outreach efficiency of the drill bit mechanism 3.

[0044] The ejection assembly 5 includes a sliding rod 51 slidably connected to the inner wall of the fixed plate 47, a fixing frame 52 is fixedly connected to the top of the fixed plate 47, a toothed roller 53 is rotatably connected to the inner wall of the fixing frame 52, a spring 57 is fixedly connected to the bottom of the fixed plate 47, and one end of the spring 57 away from the fixed plate 47 is fixedly connected to the top of the fixing ring 45.

[0045] The ejection assembly 5 also includes a limit spring piece 54 fixedly connected to the other end of the limit spring piece 54, and the limit spring block 56 is fixedly connected to the outer wall of the limit spring block 56. The outer wall of the limit spring block 56 contacts the outer wall of the toothed roller 53. The bottom of the sliding rod 51 is fixedly connected with an ejection plate 55. After the sampling is completed, as the electric telescopic rod 11 extends, the drill tube 23 will drive the sample to move upward. At this time, the staff pushes the sliding rod 51 to force the sliding rod 51 to move downward. At this time, the outer wall of the sliding rod 51 contacts the outer wall of the toothed roller 53, and the toothed roller 53 is in a stopped state due to the limit of the limit spring piece 54 and the ejection plate 55, and the friction between the toothed roller 53 and the sliding rod 51 will drive the fixed frame 52 and the fixed plate 47 along the inner wall of the drill tube 23 When the wall slides downward and the fixed plate 47 moves downward, the distance between the fixed plate 47 and the fixed ring 45 is reduced. When the pressure of the spring 2 57 exceeds the excessive pressure, the downward force of the fixed plate 47 will drive the fixed ring 45 to move downward through the spring 2 57. The downward movement of the fixed ring 45 forces the bottom arc panel 33 to open outward. As the sliding rod 51 continues to move downward, the thrust generated by the sliding rod 51 will exceed the limit of the toothed roller 53 and the limiting spring block 56, causing the limiting spring piece 54 to rotate. The sliding rod 51 moves downward, which will drive the push-out plate 55 to move downward along the inner wall of the containing tube 24, pushing the sample inside the containing tube 24 outward. Through the application of the above-mentioned components, the sample soil is prevented from becoming loose during discharge, thereby affecting the detection accuracy.

[0046] The method for using the deep soil sampling device comprises the following steps:

[0047] S1: Push the device to determine the position;

[0048] S2: Turn on the power;

[0049] S3: Push out the sample.

[0050] A specific application of this embodiment is as follows: before use, the vehicle frame 1 is pushed to the desired position, the drill mechanism 3 is aligned with the drilling position, and the power of the numerical control motor 14 and the electric telescopic rod 11 is turned on. At this time, the electric telescopic rod 11 contracts, forcing the mounting plate 12 to move downward. At this time, the mounting plate 12 will drive the numerical control motor 14 to move downward synchronously, and the numerical control motor 14 drives the gear ring 22 and the drill tube 23 to rotate clockwise through the gear 21. When the drill tube 23 rotates clockwise, the inclined contact blade 34 and the arc plate 33 will first contact the soil surface, and then the inclined contact blade 34 and the arc plate 33 will first contact the soil surface. Under the influence of clockwise rotation, the multiple arc panels 33 will move closer to the center of the drill tube 23, so that the multiple arc panels 33 form a cone shape, so as to prevent the shallow soil from entering the receiving tube 24 during the early drilling, and to prevent the shallow soil from affecting the sample accuracy of the deep soil; when the drill bit mechanism 3 reaches the required position, the CNC motor 14 rotates counterclockwise, and the cutting edge of the inclined contact blade 34 will contact the soil and force the soil to pass through the outflow groove 37, so that the arc panel 33 and the inclined contact blade 34 rotate outward with the rotating column 32 as the center of gravity, presenting as shown in the figure. Figure 6 In the state shown, as the electric telescopic rod 11 continues to contract, the deep soil will enter the containing tube 24, and after taking enough samples, the CNC motor 14 will rotate clockwise again to close the multiple arc panels 33 and the inclined contact blades 34, and then the electric telescopic rod 11 will extend to complete the sampling of the sample. Through the application of the above components, the equipment can avoid contamination of the sample by the shallow soil during the sampling process.

[0051] Taking advantage of the fact that when the drill tube 23 rotates counterclockwise, the arc panel 33 will rotate downward with the rotating column 32 as the center, a control component 4 is provided inside the equipment. When the arc panel 33 rotates, the arc panel 33 drives the installation triangle plate 35 to rotate downward synchronously, and the installation triangle plate 35 drives the piston block 1 42 to move downward along the inner wall of the hydraulic groove 31 through the rotating rod 41. At this time, the piston block 1 42 moves downward through the top liquid to drive the piston block 2 43 and the fixed column 44 to move downward synchronously. When multiple fixed columns 44 move downward, they will drive the fixing ring 45 to move downward synchronously. In this process, the fixing ring 45 will control the speed and length of the multiple fixed columns 44 and the piston block 2 43 to move downward, and indirectly control the outward rotation angle of the multiple arc panels 33, so that the outward expansion angles of the multiple arc panels 33 are equal, so as to avoid the different outward expansion rates of the arc panels 33, which will cause the sample soil to be crushed and affect the detection accuracy of the sample. 45 controls the length characteristics of the downward movement of multiple fixed columns 44. A spring 1 46 and a fixed plate 47 are arranged inside the equipment. During the outward expansion of the drill bit mechanism 3, if one of the arc panels 33 is blocked during expansion, the corresponding piston block 2 43 will find it difficult to slide downward along the inner wall of the hydraulic groove 31. At this time, the blocked piston block 2 43 limits the downward movement of the fixing ring 45 through the fixed column 44, and the obstruction of the fixing ring 45 will limit the downward movement of the remaining piston blocks 2 43. In this process, the unobstructed multiple piston blocks 2 43 are still affected by the bottom arc panel 33 to generate a pulling force downward. The pulling force generated by the downward movement of the multiple unobstructed piston blocks 2 43 will be transmitted to the fixing ring 45 through the corresponding fixing column 44, so that the fixing ring 45 pushes the blocked fixing column 44 and the piston block 2 43 to move downward. Through the application of the above components, it is avoided that a single arc panel 33 is blocked and the expansion efficiency of the drill bit mechanism 3 is affected.

[0052] After the sampling is completed, as the electric telescopic rod 11 is extended, the drill tube 23 will drive the sample to move upward. At this time, the staff will push the sliding rod 51 to force the sliding rod 51 to move downward. At this time, the outer wall of the sliding rod 51 contacts the outer wall of the toothed roller 53, and the toothed roller 53 is limited by the position spring 54 and the push plate 55 and is in a stopped state. The friction between the toothed roller 53 and the sliding rod 51 will drive the fixing frame 52 and the fixing plate 47 to slide downward along the inner wall of the drill tube 23. When the fixing plate 47 moves downward, the distance between the fixing plate 47 and the fixing ring 45 is reduced. When the spring 57 exceeds When the pressure is too great, the downward force of the fixed plate 47 will drive the fixed ring 45 to move downward through the spring 2 57. The downward movement of the fixed ring 45 forces the bottom arc panel 33 to open outward, and as the sliding rod 51 continues to move downward, the thrust generated by the sliding rod 51 will exceed the limit of the toothed roller 53 and the limiting spring block 56, causing the limiting spring piece 54 to rotate. The downward movement of the sliding rod 51 will drive the push-out plate 55 to move downward along the inner wall of the containing tube 24, pushing the sample inside the containing tube 24 outward. Through the application of the above-mentioned components, the sample soil can be prevented from becoming loose during discharge, thereby affecting the detection accuracy.
