Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and in particular to a soil geographic information collection device for national land space planning. Background Art

[0002] In order to provide accurate and comprehensive basic geographic data for national land space planning, it is usually necessary to sample the soil and send the soil samples to the laboratory for analysis. In this way, important parameters such as soil pH, organic matter content, and nutrient levels can be understood.

[0003] When sampling forest soil, plant roots are often scattered in the soil. The presence of these roots will affect the physical structure of the soil, making the soil around the roots usually looser. Therefore, when the sampling tool contacts the tree roots, the roots will move, causing the roots to move relative to the surrounding soil. In this process, the scattered roots will disrupt the soil distribution in the sampling tool, change the original structure of the soil, and thus affect the subsequent test results.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0022] Embodiment 1: A soil geographic information collection device for national land space planning, combined with Figure 1-Figure 6 As shown, it includes a base 1, the base 1 is detachably mounted with a support frame 2, a driving motor 3 and a driving push rod 4 are mounted on the support frame 2, the telescopic end of the driving push rod 4 is rotatably connected with a transmission shaft 5, a transmission module 301 is mounted on the support frame 2, the output shaft of the driving motor 3 is fixedly connected to the input end of the transmission module 301, and the transmission shaft 5 is spline-connected to the output end of the transmission module 301; an inner cylinder 6 is fixedly connected to the lower end of the transmission shaft 5, and the lower side of the inner cylinder 6 is fixedly connected with first protrusions 601 distributed at intervals; a mounting plate 7 is slidably connected to the transmission shaft 5, and the inner cylinder 6 is connected to the mounting plate 7. A first elastic member is fixed between the mounting plates 7; the outer cylinder 8 is rotatably connected to the mounting plate 7, and second protrusions 801 distributed at intervals are fixed to the lower side of the outer cylinder 8; a transmission assembly is arranged on the outer cylinder 8, and is used to drive the outer cylinder 8 to rotate; the first protrusion 601 is provided with a tip, and the curvature of the first protrusion 601 close to the axis side of the inner cylinder 6 is consistent with the curvature of the inner wall of the outer cylinder 8; the second protrusion 801 is provided with a tip, and the curvature of the second protrusion 801 close to the axis side of the outer cylinder 8 is consistent with the curvature of the inner wall of the outer cylinder 8; the inner cylinder 6 is located in the middle of the outer cylinder 8.

[0023] In the above scheme, a method for fixing the tree roots is proposed to facilitate their cutting; the base 1 is used to fix and position the entire device; the transmission module 301 is two pulleys and a belt, one of which is fixedly connected to the output shaft of the drive motor 3, and the other pulley is slidably connected to the transmission shaft 5, and both pulleys are rotatably connected to the support frame 2; the inner cylinder 6 is used to sample the soil; the first elastic member on the inner cylinder 6 is a spring (which can also be stretched); the misalignment of the hypotenuse of the first protrusion 601 and the hypotenuse of the second protrusion 801 during rotation is utilized to shear the tree roots and accelerate the crushing of the tree roots; initially, the lower side of the inner cylinder 6 is not aligned with the lower side of the outer cylinder 8.

[0024] Further, combined with Figure 4 , Figure 5 and Figure 7 As shown, the transmission assembly includes a fixed disk 21, which is fixedly connected to the outer cylinder 8. The fixed disk 21 is provided with spaced connecting frames 22, and the spaced connecting frames 22 are commonly fixed with a power shaft 23. The power shaft 23 is slidably and rotationally connected to the transmission shaft 5. The output shaft of the driving motor 3 is spline-connected with a transmission member 24, and the transmission member 24 is used to drive the power shaft 23 to rotate. The transmission shaft 5 is rotatably connected to a connecting plate 501, and the connecting plate 501 is rotatably connected to the transmission member 24.

[0025] In the above scheme, a method of driving the outer cylinder 8 to rotate is mainly proposed, and the rotation direction of the outer cylinder 8 is opposite to the rotation direction of the inner cylinder 6; the number of connecting frames 22 in this article is two; the upper side of the power shaft 23 and the lower side of the transmission member 24 are both provided with rubber circular plates, so as to increase the friction between the two and ensure normal transmission between the two. In the initial state, the rubber circular plate of the power shaft 23 and the rubber circular plate of the transmission member 24 are not in contact; the connecting plate 501 is slidably connected to the support frame 2 to improve the stability of the connecting plate 501.

[0026] Workflow: When using this device for sampling, the operator moves the device to the target position, aligns the axis of the outer cylinder 8 with the center of the target position, and then turns on the drive motor 3 and the drive push rod 4. The output shaft of the drive motor 3 drives the drive shaft 5 to rotate through the transmission module 301, and the output shaft of the drive motor 3 drives the transmission member 24 to rotate through the spline, and the drive shaft 5 drives the inner cylinder 6 to rotate. The telescopic end of the drive push rod 4 drives the drive shaft 5 to move downward, and the drive shaft 5 drives the inner cylinder 6 to move downward. The inner cylinder 6 drives the outer cylinder 8 to move synchronously through the first elastic member and the mounting plate 7, and the drive shaft 5 drives the transmission member 24 to move downward through the connecting plate 501.

[0027] In the process of the inner cylinder 6 and the outer cylinder 8 moving downward together, when the outer cylinder 8 contacts the soil, the soil generates resistance to the outer cylinder 8, the inner cylinder 6 and the outer cylinder 8 generate a brief relative movement, and the first elastic member on the inner cylinder 6 is gradually stretched. When the resistance of the soil is consistent with the elastic force of the first elastic member on the inner cylinder 6, the inner cylinder 6 drives the outer cylinder 8 to move downward again through the first elastic member and the mounting plate 7 (at this time, the lower side of the outer cylinder 8 is still not aligned with the lower side of the inner cylinder 6), and the outer cylinder 8 gradually penetrates into the soil. After the inner cylinder 6 contacts the soil, the rotating inner cylinder 6 drills the soil, so that the soil at the sampling position enters the inner cylinder 6.

[0028] When the outer cylinder 8 is moving downward, if the outer cylinder 8 contacts the tree roots in the soil, the second protrusions 801 squeeze the tree roots so that the tree roots are located between two adjacent second protrusions 801. At this time, the tree roots are fixed by the two adjacent second protrusions 801, and the tree roots block the outer cylinder 8, and the outer cylinder 8 cannot move. The inner cylinder 6 continues to move, and the first elastic member on the inner cylinder 6 continues to stretch until the inner cylinder 6 moves to contact the tree roots, and the rotating first protrusions 601 break the tree roots. In this process, the tree roots are fixed by the second protrusions 801, and the tree roots cannot deflect relative to the first protrusions 601, so that the shear force applied by the first protrusions 601 fully acts on the tree roots, accelerating the speed of the tree root fracture. At the same time, through the fixation of the second protrusions 801, the probability of root displacement is reduced, thereby ensuring the distribution state of the soil in the inner cylinder 6.

[0029] During the process of the outer cylinder 8 fixing the tree roots, the outer cylinder 8 moves upward relative to the inner cylinder 6, and the outer cylinder 8 drives the power shaft 23 to move upward through the fixing disk 21 and the connecting frame 22, and the distance between the power shaft 23 and the transmission member 24 gradually decreases. During this process, if the tree roots are not cut off and the lower side of the outer cylinder 8 is aligned with the lower side of the inner cylinder 6, the power shaft 23 contacts the transmission member 24, and then the transmission member 24 drives the power shaft 23 to rotate through friction, and the power shaft 23 drives the outer cylinder 8 to rotate through the connecting frame 22 and the fixing disk 21. At this time, the rotation directions of the outer cylinder 8 and the inner cylinder 6 are opposite. The relative rotation speed of the outer cylinder 8 and the inner cylinder 6 is accelerated by the rotation of the outer cylinder 8, and the relative rotation of the first protrusion 601 and the second protrusion 801 is utilized to shear the tree roots on the sides between the two adjacent sides, thereby accelerating the fracture of the tree roots and ensuring the integrity of the soil taken by the device.

[0030] After the tree root breaks, the outer cylinder 8 continues to move downward under the action of the first elastic member on the inner cylinder 6, the power shaft 23 and the transmission member 24 gradually lose contact and move away from each other, the outer cylinder 8 stops rotating, and the inner cylinder 6 continues to move downward for sampling until the resistance exerted by the soil on the outer cylinder 8 is balanced with the elastic force of the first elastic member on the inner cylinder 6 again, the inner cylinder 6 and the outer cylinder 8 stop moving relative to each other, and as the inner cylinder 6 moves, the outer cylinder 8 continues to move downward until the inner cylinder 6 moves to the target depth, the operator turns off the drive motor 3 and the drive push rod 4, and takes the inner cylinder 6 out of the soil, and then takes out the soil in the inner cylinder 6, thus completing the soil sampling work, and then the operator moves the device to the next sampling position, and repeats all the above operations to sample the next mark point.

[0031] In the above-mentioned embodiment, the connecting frame 22 and the fixing plate 21 are fixedly connected; however, in the following embodiment, the connecting frame 22 and the fixing plate 21 are slidably connected.

[0032] Example 2: Based on Example 1, Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, it also includes mounting posts 31, the number of which is consistent with the number of connecting frames 22, and both are fixed to the fixed disk 21. The mounting posts 31 are rotatably connected to spring distance sensors 32. The telescopic ends of the spring distance sensors 32 are ball-jointed with the connecting frame 22. The connecting frame 22 is slidably connected to the fixed disk 21, and a second elastic member is fixed therebetween, which is a spring.

[0033] In the above scheme, a method for detecting the resistance to the rotation of the outer cylinder 8 is proposed, and according to the resistance value of the outer cylinder 8, the rotation state of the inner cylinder 6 and the outer cylinder 8 is adjusted, thereby accelerating the speed of tree root breaking; the number of mounting columns 31 is two, and the spring distance sensor 32 is an existing device, which is used to measure the resistance of the outer cylinder 8 by compression or extension of the spring distance sensor 32, that is, when the resistance of the outer cylinder 8 increases, the outer cylinder 8 and the power shaft 23 rotate relative to each other, and at this time the spring distance sensor 32 is extended, and the spring distance sensor 32 is electrically connected to the drive motor 3. When the spring distance sensor 32 is extended, the rotation direction of the output shaft of the drive motor 3 changes, and periodic reciprocating rotation is performed.

[0034] Working principle: When the outer cylinder 8 moves downward and rotates circumferentially, the outer cylinder 8 and the inner cylinder 6 jointly shear the tree roots, causing the tree roots to break quickly. If the tree roots cannot break during this process and generate resistance to the rotation of the outer cylinder 8, when the resistance to the outer cylinder 8 is greater than the elastic force of the second elastic member on the fixed disk 21, the connecting frame 22 and the fixed disk 21 slide relative to each other. At this time, the rotation speed of the outer cylinder 8 decreases, causing the rotation speed of the fixed disk 21 to decrease. During this process, the power shaft 23 continuously drives the connecting frame 22 to rotate, and the fixed disk 21 The disk 21 drives the spring distance sensor 32 to rotate, and the spring distance sensor 32 deflects and stretches. After the spring distance sensor 32 stretches, the spring distance sensor 32 detects the rotational resistance of the outer cylinder 8, and controls the drive motor 3. The output shaft of the drive motor 3 changes the rotation direction, so that the rotation direction of the outer cylinder 8 changes, and the direction of cutting the tree roots by the outer cylinder 8 and the inner cylinder 6 is changed, thereby changing the force direction of the tree roots, reducing the resistance of the outer cylinder 8, and preventing the tree roots from getting stuck in the outer cylinder 8 and the outer cylinder 8 driving the tree roots to move.

[0035] After the resistance of the outer cylinder 8 is reduced, the second elastic member on the fixed disk 21 is reset, and drives the connecting frame 22 and the fixed disk 21 to return to their original positions. At the same time, under the elastic force of the spring distance sensor 32, the spring distance sensor 32 restores its initial length, and the connecting frame 22 and the fixed disk 21 rotate at the same speed.

[0036] Embodiment 3: Based on Embodiment 2, Figure 5 , Figure 7 and Figure 8 As shown, it also includes an elastic telescopic rod 41, which is fixed to the inner tube 6, and its telescopic end is fixed to the mounting plate 7. A pressure sensor is installed inside the elastic telescopic rod 41, so that the pressure sensor senses the magnitude of the torque applied to the elastic telescopic rod 41, thereby controlling the speed of movement of the telescopic end of the driving push rod 4.

[0037] When using the device for sampling, when the outer tube 8 contacts the soil, the outer tube 8 and the inner tube 6 move relative to each other, at which time the elastic telescopic rod 41 is stretched, and the value detected by the pressure sensor inside it decreases, until the outer tube 8 and the inner tube 6 move synchronously, the elastic telescopic rod 41 stops stretching, and the value of the pressure sensor inside it stops changing.

[0038] When the outer cylinder 8 contacts the tree roots, the tree roots block the outer cylinder 8. At this time, the outer cylinder 8 and the inner cylinder 6 continue to move relative to each other, and the elastic telescopic rod 41 continues to deform until the value detected by the pressure sensor in the elastic telescopic rod 41 exceeds the set threshold. The pressure sensor in the elastic telescopic rod 41 controls the driving push rod 4 to reduce the extension speed of the telescopic end of the driving push rod 4, thereby reducing the downward movement speed of the outer cylinder 8 and the inner cylinder 6, thereby reducing the squeezing pressure of the outer cylinder 8 on the tree roots, prolonging the contact time between the outer cylinder 8 and the tree roots, and ensuring that the outer cylinder 8 cuts off the tree roots.

[0039] When the outer tube 8 and the inner tube 6 stop moving relative to each other and the distance between them returns to the initial state, the elastic telescopic rod 41 is stretched and also returns to the initial state. At this time, the value of the pressure sensor in the elastic telescopic rod 41 is restored, and the moving speed of the telescopic end of the driving push rod 4 is controlled to return to the initial speed.

[0040] Embodiment 4: Based on Embodiment 3, Figure 8-Figure 13 As shown, it also includes: a fixed shell 51, fixedly connected to the inner cylinder 6; a sliding sleeve 52, slidably connected to the fixed shell 51, and a third elastic member is fixedly connected between the two, a limiting groove is provided on the fixed shell 51, and a convex ball is provided on the sliding sleeve 52, and the convex ball of the sliding sleeve 52 is located in the limiting groove of the fixed shell 51 and slides; a flexible sleeve 53, one side of which is fixedly connected to the sliding sleeve 52, and the other side is fixedly connected to the fixed shell 51; a power component is arranged between the support frame 2 and the inner cylinder 6, and is used to deform the flexible sleeve 53 and block the lower side of the fixed shell 51.

[0041] In the above scheme, a method for sealing the lower side of the inner tube 6 is proposed, so as to ensure that the soil inside the inner tube 6 will not fall off during the removal of the inner tube 6; the third elastic member of the fixed shell 51 is a torsion spring, which is used to drive the sliding sleeve 52 to reset; the flexible sleeve 53 is made of rubber, and the flexible sleeve 53 is torsional deformed to seal the lower side of the fixed shell 51. The thickness of the fixed shell 51 and the flexible sleeve 53 shown in the figure is only for easy identification and understanding. In actual production, the fixed shell 51 can be embedded in the inner tube 6, so that the inner wall of the fixed shell 51 and the inner wall of the inner tube 6 are on the same curved surface, which is convenient for entering the inner tube 6; the upper limit groove of the fixed shell 51 is composed of an inclined groove and an arc groove (such as Fig.10 As shown in FIG. 5 , the convex ball of the sliding sleeve 52 slides on the inclined groove and the arc groove of the fixed shell 51, so that the sliding sleeve 52 rotates during the downward movement of the sliding sleeve 52.

[0042] Combination Figure 2 , Figure 3 and Figure 8-Figure 13 As shown, the power assembly includes: a pull ring 61, which is slidably connected to the transmission shaft 5; a transition ring 62, which is rotatably connected to the lower side of the sliding sleeve 52. When the sliding sleeve 52 rotates, it will not drive the transition ring 62 to rotate. A pull rope 63 is fixedly connected between the pull ring 61 and the sliding sleeve 52. The pull rope 63 can be a steel wire rope. The pull rope 63 runs through the transmission shaft 5 and the inner tube 6.

[0043] Working process: After the inner cylinder 6 moves to the specified depth, the operator controls the inner cylinder 6 to stop moving and turns off the driving motor 3 by driving the push rod 4. After the transmission shaft 5 stops rotating, the operator pulls the pull ring 61 upwards, and the pull ring 61 drives the transition ring 62 to move downwards through the pull rope 63. The transition ring 62 drives the sliding sleeve 52 to move downwards, and the sliding sleeve 52 drives the convex ball thereon to slide, and the convex ball slides along the inclined groove of the fixed shell 51. In this process, the sliding sleeve 52 moves downwards along the fixed shell 51 and the two rotate relative to each other (sliding sleeve 52 moves downwards along the fixed shell 51 and the two rotate relative to each other). The third elastic member of the movable sleeve 52 stores force), the sliding sleeve 52 drives the flexible sleeve 53 to move downward, and twists the flexible sleeve 53, so that the flexible sleeve 53 is deformed during the movement, and the lower side of the fixed shell 51 is blocked (this structure is consistent with the blocking structure of the existing twist cup). During the deformation of the flexible sleeve 53, the flexible sleeve 53 isolates the soil on the lower side of the inner cylinder 6, until the convex ball of the sliding sleeve 52 moves to the arc groove of the fixed shell 51, the flexible sleeve 53 completes the deformation, and blocks the lower side of the inner cylinder 6.

[0044] After sealing the lower side of the inner cylinder 6, the operator stops pulling the pull ring 61 (but does not release it), and then the operator controls the inner cylinder 6 to move upward by driving the push rod 4, and the inner cylinder 6 drives the soil therein to move upward until the inner cylinder 6 moves out of the ground surface, and the operator releases the pull ring 61, and the sliding sleeve 52 moves upward and resets under the action of the third elastic member thereon, and the sliding sleeve 52 drives the flexible sleeve 53 to move and release the blockage of the inner cylinder 6, and at the same time, the sliding sleeve 52 drives the transition ring 62 to reset, thereby resetting the pull ring 61, and then the operator takes out the soil in the inner cylinder 6 to complete the soil sampling work.

[0045] Embodiment 5: Based on Embodiment 4, Figure 8-Figure 13 As shown, it also includes a wrapping film 71, which is fixed to the side of the flexible sleeve 53 close to the sliding sleeve 52. The wrapping film 71 is a plastic film. The wrapping film 71 fits the inner side of the flexible sleeve 53 and the inner side of the fixed shell 51. The extrusion plate 72 is located in the wrapping film 71. The extrusion plate 72 is used to make the wrapping film 71 fit with the fixed shell 51. The fixed disk 21, the upper side of the outer cylinder 8 and the upper side of the inner cylinder 6 are all provided with arc-shaped through grooves.

[0046] Working process: during the process of inserting the inner cylinder 6 into the ground, the soil gradually enters the inner cylinder 6, and the soil in the inner cylinder 6 pushes the extrusion plate 72 upward to move, so that the extrusion plate 72 drives the wrapping film 71 to unfold and make the wrapping film 71 fit with the inner wall of the inner cylinder 6, until the inner cylinder 6 reaches the specified position.

[0047] During the process of the flexible sleeve 53 sealing the inner cylinder 6, the flexible sleeve 53 drives the wrapping film 71 to move synchronously, thereby isolating the soil on the lower side of the inner cylinder 6. After the flexible sleeve 53 seals the inner cylinder 6, the flexible sleeve 53 drives the wrapping film 71 to synchronously seal the lower side of the inner cylinder 6. After the inner cylinder 6 is moved out of the ground, the operator separates the lower side of the wrapping film 71 from the flexible sleeve 53, and then resets the flexible sleeve 53. At this time, the wrapping film 71 wraps the soil in the inner cylinder 6. The operator inserts a straight rod into the inner cylinder 6 (through the fixed disk 21, the upper side of the outer cylinder 8 and the arc-shaped through groove on the upper side of the inner cylinder 6), and pushes the extrusion plate 72 to move downward. The extrusion plate 72 pushes The soil in the inner cylinder 6 moves downward. During this process, the operator synchronously pulls the lower side of the wrapping film 71 to remove the wrapping film 71 from the inner cylinder 6. The wrapping film 71 prevents the soil from contacting the inner cylinder 6, and the wrapping film 71 is used to drive the soil to move, thereby reducing the friction between the soil and the inner cylinder 6 and ensuring the integrity of the removed soil. After taking out the soil, the operator puts the wrapping film 71 into the inner cylinder 6, re-fits the wrapping film 71 with the inner side of the flexible sleeve 53 and the inner side of the fixed shell 51, and fixes the lower side of the wrapping film 71 to the lower side of the flexible sleeve 53, and repeats the above steps to sample the soil at the next location.
