Description

Technical Field

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

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

[0003] During the process of 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 comes into contact with the tree roots, the tree roots will be driven to move, resulting in relative displacement between the tree roots and the surrounding soil. During this process, the scattered tree roots will disrupt the soil distribution state inside the sampling tool and change the original structure of the soil, thus affecting the subsequent test results. Summary of the Invention

[0006] Further, the first protrusion is provided with a tip, and the bending degree of the side of the first protrusion close to the axis of the inner cylinder is the same as the bending degree of the inner wall of the outer cylinder.

[0007] Further, the second protrusion is provided with a tip, and the bending degree of the side of the second protrusion close to the axis of the outer cylinder is the same as the bending degree of the inner wall of the outer cylinder.

[0008] Further, the inner cylinder is located in the middle of the outer cylinder.

[0009] Further, the transmission assembly includes a fixed disk, which is fixedly connected to the outer cylinder. The fixed disk is provided with connecting frames distributed at intervals. The connecting frames distributed at intervals are jointly fixedly connected to a power shaft. The power shaft is slidably and rotatably connected to the transmission shaft. The output shaft of the driving motor is splined to a transmission member, and the transmission member is used to drive the power shaft to rotate. The transmission shaft is rotatably connected to a connecting plate, and the connecting plate is rotatably connected to the transmission member.

[0010] Further, it further includes: Mounting columns, the number of which is the same as that of the connecting frames, are all fixedly connected to the fixed disk. The mounting columns are rotatably connected to spring distance sensors. The telescopic ends of the spring distance sensors are ball-jointed to the connecting frames. The connecting frames are slidably connected to the fixed disk, and a second elastic member is fixedly connected between the two.

[0011] Further, it further includes an elastic telescopic rod, which is fixedly connected to the inner cylinder, and its telescopic end is fixedly connected to the mounting plate.

[0012] Further, it further includes: A fixed shell, which is fixedly connected inside the inner cylinder; A sliding sleeve, which is slidably connected to the fixed shell, and a third elastic member is fixedly connected between the two. The fixed shell is provided with a limiting groove, and the sliding sleeve is provided with a convex ball.

Detailed implementation manners

[0021] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited.

[0022] Embodiment 1: A geographic information collection device for territorial space planning, in combination with Figures 1-6 as shown, includes a base 1, the base 1 is detachably installed with a support frame 2, a drive motor 3 and a drive push rod 4 are installed on the support frame 2, the telescopic end of the drive push rod 4 is rotatably connected to a transmission shaft 5, a transmission module 301 is installed on the support frame 2, the output shaft of the drive motor 3 is fixedly connected to the input end of the transmission module 301, and the transmission shaft 5 is in spline connection with the output end of the transmission module 301; an inner cylinder 6, fixedly connected to the lower end of the transmission shaft 5, and a plurality of spaced-apart first protrusions 601 are fixedly connected to the lower side of the inner cylinder 6; a mounting plate 7, slidably connected to the transmission shaft 5, and a first elastic member is fixedly connected between the inner cylinder 6 and the mounting plate 7; an outer cylinder 8, rotatably connected to the mounting plate 7, and a plurality of spaced-apart second protrusions 801 are fixedly connected to the lower side of the outer cylinder 8; a transmission assembly, arranged on the outer cylinder 8, for driving the outer cylinder 8 to rotate; the first protrusion 601 is provided with a tip, and the bending degree of the side surface of the first protrusion 601 close to the axis of the inner cylinder 6 is the same as the bending degree of the inner wall of the outer cylinder 8; the second protrusion 801 is provided with a tip, and the bending degree of the side surface of the second protrusion 801 close to the axis of the outer cylinder 8 is the same as the bending degree 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 solution, a method for fixing the tree root is proposed to facilitate its cutting; the base 1 is used to fix and position the whole device; the transmission module 301 consists of two pulleys and a belt. One pulley is fixedly connected to the output shaft of the driving motor 3, and the other pulley is slidably connected to the transmission shaft 5. At the same time, both pulleys are rotatably connected to the support frame 2; the inner cylinder 6 is used for soil sampling; the first elastic member on the inner cylinder 6 is a spring (which can also be stretched); by using the dislocation when the hypotenuse of the first protrusion 601 and the hypotenuse of the second protrusion 801 rotate, the tree root is sheared to accelerate the fragmentation of the tree root; initially, the lower side of the inner cylinder 6 is not aligned with the lower side of the outer cylinder 8.

[0024] Further, as shown in Figure 4 、 Figure 5 and Figure 7 the transmission component includes a fixed disk 21, which is fixedly connected to the outer cylinder 8. The fixed disk 21 is provided with connecting frames 22 distributed at intervals. The connecting frames 22 distributed at intervals are jointly fixedly connected to a power shaft 23. The power shaft 23 is slidably and rotatably connected to the transmission shaft 5. The output shaft of the driving motor 3 is spline-connected to a transmission member 24. 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 solution, a method for driving the outer cylinder 8 to rotate is mainly proposed, and the rotation direction of the outer cylinder 8 is opposite to that of the inner cylinder 6; the number of the connecting frames 22 in this article is two; rubber circular plates are provided on the upper side of the power shaft 23 and the lower side of the transmission member 24, so as to increase the friction force between the two and ensure the normal transmission between the two. In the initial state, the rubber circular plates of the power shaft 23 and the transmission member 24 do not contact; the connecting plate 501 is slidably connected to the support frame 2 to improve the stability of the connecting plate 501.

[0026] Working process: When using this device for sampling, the operator moves this device to the target position, aligns the axis of the outer cylinder 8 with the center of the target position. Then the operator turns on the driving motor 3 and the driving push rod 4. The output shaft of the driving motor 3 drives the transmission shaft 5 to rotate through the transmission module 301. The output shaft of the driving motor 3 drives the transmission member 24 to rotate through splines. The transmission shaft 5 drives the inner cylinder 6 to rotate. The telescopic end of the driving push rod 4 drives the transmission shaft 5 to move downward. The transmission 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. The transmission shaft 5 drives the transmission member 24 to move downward through the connecting plate 501.

[0027] During the downward movement of the inner cylinder 6 and the outer cylinder 8 together, when the outer cylinder 8 contacts the soil, the soil generates resistance to the outer cylinder 8, and the inner cylinder 6 and the outer cylinder 8 have a brief relative movement. Moreover, 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 and the lower side of the inner cylinder 6 are still not aligned). 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, enabling the soil at the sampling position to enter the inner cylinder 6.

[0028] During the downward movement of the outer cylinder 8, when the outer cylinder 8 contacts the tree roots in the soil, the second protrusion 801 squeezes the tree roots, causing the tree roots to be 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, preventing the outer cylinder 8 from moving. 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. The rotating first protrusion 601 breaks the tree roots. During this process, the tree roots are fixed by the second protrusions 801 and cannot deflect relative to the first protrusion 601. Thus, the shear force applied by the first protrusion 601 fully acts on the tree roots, accelerating the speed of the tree roots breaking. At the same time, through the fixation of the second protrusions 801, the probability of the tree roots shifting is reduced, 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. The outer cylinder 8 drives the power shaft 23 to move upward through the fixing disk 21 and the connecting frame 22. 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. Subsequently, the transmission member 24 drives the power shaft 23 to rotate through friction. 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. Through the rotation of the outer cylinder 8, the relative rotation speed of the outer cylinder 8 and the inner cylinder 6 is accelerated, and the side edges between the adjacent first protrusion 601 and the second protrusion 801 shear the tree roots through their relative rotation, accelerating the breakage of the tree roots and ensuring the integrity of the soil taken by this device.

[0030] After the root of the tree 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 with each other 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 relative movement between the inner cylinder 6 and the outer cylinder 8 stops. 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 driving motor 3 and the driving push rod 4, and takes out the inner cylinder 6 from the soil. Subsequently, the soil in the inner cylinder 6 is taken out, thus completing the soil sampling work. Then the operator moves the device to the next sampling position and repeats all the above operations to sample the next point.

[0031] In the above embodiment, the connecting frame 22 and the fixed disk 21 are fixedly connected; however, in the following embodiment, the connecting frame 22 and the fixed disk 21 are slidably connected.

[0032] Embodiment 2: On the basis of Embodiment 1, in combination with Figure 4 , Figure 5 , Figure 7 and Figure 8 as shown, it further includes mounting columns 31, the number of which is the same as that of the connecting frames 22, and they are all fixedly connected to the fixed disk 21. The mounting columns 31 are rotatably connected with spring distance sensors 32. The telescopic ends of the spring distance sensors 32 are ball-jointed with the connecting frames 22. The connecting frames 22 and the fixed disk 21 are slidably connected, and a second elastic member is fixedly connected between the two. The second elastic member is a spring.

[0033] In the above solution, a method for detecting the resistance of the outer cylinder 8 to rotation is proposed, and according to the resistance value of the outer cylinder 8, the rotation states of the inner cylinder 6 and the outer cylinder 8 are adjusted, thereby accelerating the speed of root breakage; the number of the mounting columns 31 is two, and the spring distance sensors 32 are existing devices, which are used to measure the resistance exerted on the outer cylinder 8 through the compression or stretching of the spring distance sensors 32. That is, when the resistance exerted on the outer cylinder 8 increases, the outer cylinder 8 rotates relative to the power shaft 23. At this time, the spring distance sensors 32 extend. The spring distance sensors 32 are electrically connected to the driving motor 3. When the spring distance sensors 32 extend, the rotation direction of the output shaft of the driving motor 3 changes and performs periodic reciprocating rotation.

[0034] Working principle: During the downward movement and circumferential rotation of the outer cylinder 8, the outer cylinder 8 and the inner cylinder 6 jointly shear the tree roots, causing the tree roots to break quickly. If during this process, the tree roots cannot break and generate resistance to the rotation of the outer cylinder 8, when the resistance received by the outer cylinder 8 is greater than the elastic force of the second elastic member on the fixed disk 21, relative sliding occurs between the connecting frame 22 and the fixed disk 21. 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, the fixed disk 21 drives the spring distance sensor 32 to rotate, and the spring distance sensor 32 deflects and elongates. After the spring distance sensor 32 elongates, the spring distance sensor 32 detects the rotational resistance received by the outer cylinder 8. Thus, the drive motor 3 is controlled, and the output shaft of the drive motor 3 changes the rotation direction, causing the rotation direction of the outer cylinder 8 to change, changing the cutting direction of the tree roots by the outer cylinder 8 and the inner cylinder 6, and further changing the force direction of the tree roots, reducing the resistance received by the outer cylinder 8, and preventing the tree roots from jamming the outer cylinder 8 and the outer cylinder 8 from driving the tree roots to move.

[0035] After the resistance received by the outer cylinder 8 decreases, the second elastic member on the fixed disk 21 resets 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 returns to its initial length, and the rotational speeds of the connecting frame 22 and the fixed disk 21 are the same.

[0036] Embodiment 3: On the basis of Embodiment 2, as shown in Figure 5 、 Figure 7 and Figure 8 , it further includes an elastic telescopic rod 41. The elastic telescopic rod 41 is fixedly connected to the inner cylinder 6, and its telescopic end is fixedly connected to the mounting plate 7. A pressure sensor is installed inside the elastic telescopic rod 41. Thus, the magnitude of the torque received by the elastic telescopic rod 41 is sensed through the pressure sensor, and further the moving speed of the telescopic end of the drive push rod 4 is controlled.

[0037] When using this device for sampling, when the outer cylinder 8 contacts the soil, the outer cylinder 8 and the inner cylinder 6 move relative to each other. At this time, the elastic telescopic rod 41 is stretched, and the value detected by the pressure sensor inside it decreases. Until the outer cylinder 8 and the inner cylinder 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 inside the elastic telescopic rod 41 exceeds the set threshold, the pressure sensor inside the elastic telescopic rod 41 controls the drive push rod 4, and the moving speed of the telescopic end of the drive push rod 4 decreases, thereby reducing the downward moving speed of the outer cylinder 8 and the inner cylinder 6. Thus, the extrusion force of the outer cylinder 8 on the tree roots is reduced, the contact time between the outer cylinder 8 and the tree roots is extended, and further it is ensured that the outer cylinder 8 cuts off the tree roots.

[0039] When the outer cylinder 8 and the inner cylinder 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: On the basis of Embodiment 3, in combination with Figures 8-13 As shown, it further includes: a fixed shell 51, fixedly connected inside 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. The convex ball of the sliding sleeve 52 slides in the limiting groove of the fixed shell 51; a flexible sleeve 53, one side is fixedly connected to the sliding sleeve 52, and the other side is fixedly connected to the fixed shell 51; a power assembly, arranged between the support frame 2 and the inner cylinder 6, for deforming the flexible sleeve 53 and blocking the lower side of the fixed shell 51.

[0041] In the above solution, it aims to propose a way to block the lower side of the inner cylinder 6, so as to ensure that the soil inside the inner cylinder 6 will not fall during the process of taking out the inner cylinder 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 material, and through the torsional deformation of the flexible sleeve 53, it blocks the lower side of the fixed shell 51. The thicknesses of the fixed shell 51 and the flexible sleeve 53 shown in the figure are only for easy identification and understanding. In actual production, the fixed shell 51 can be embedded in the inner cylinder 6, so that the inner wall of the fixed shell 51 and the inner wall of the inner cylinder 6 are on the same curved surface, which is convenient for entering the inner cylinder 6; the limiting groove on the fixed shell 51 is composed of an inclined groove and an arc groove (as Figure 10 shown), and 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 process of moving downward.

[0042] In combination with Figure 2 、 Figure 3 and Figures 8-13 As shown, the power assembly includes: a pull ring 61, slidably connected to the transmission shaft 5; a transition ring 62, 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, and the pull rope 63 penetrates through the transmission shaft 5 and the inner cylinder 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, Figures 8-13 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 blocking the inner cylinder 6 with the flexible sleeve 53, the flexible sleeve 53 drives the wrapping film 71 to move synchronously, thus separating the soil on the lower side of the inner cylinder 6. After the flexible sleeve 53 blocks the inner cylinder 6, the flexible sleeve 53 drives the wrapping film 71 to synchronously block the lower side of the inner cylinder 6. After the inner cylinder 6 is removed from the ground surface, 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 inside the inner cylinder 6. The operator inserts a straight rod into the inner cylinder 6 (through the fixing plate 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 downward. The extrusion plate 72 pushes the soil inside the inner cylinder 6 downward. During this process, the operator synchronously drags the lower side of the wrapping film 71, thus taking out the wrapping film 71 from the inner cylinder 6. The wrapping film 71 makes the soil not contact the inner cylinder 6, and drives the soil to move by using the wrapping film 71, thus reducing the friction between the soil and the inner cylinder 6 and ensuring the integrity of the taken-out soil. After the soil is taken out, the operator puts the wrapping film 71 into the inner cylinder 6, makes the wrapping film 71 fit with the inner side of the flexible sleeve 53 and the inner side of the fixed shell 51 again, and fixes the lower side of the wrapping film 71 on the lower side of the flexible sleeve 53. Repeat the above steps to sample the soil at the next location.
