A box 2 is installed on the mobile vehicle 1, and a mobile power supply and a PLC control system are arranged in the box 2. When it is necessary to measure the land to be evaluated, the sealed door 9 on the side of the moving direction of the box 2 is opened, and then the surveyor controls the mobile vehicle 1 to move to the place to be measured through a handheld controller, and then controls the clamping and transferring mechanism 5 to work, so that it clamps and transfers the equidistantly arranged marking rods 4 in the cavity 21 to the outside of the box 2, and makes the bottom of the marking rod 4 move downward along the guide pushing mechanism 6, so that the marking rod 4 can be inserted into the boundary of the land to be measured, and then the mobile vehicle 1 is driven to move to the next boundary point, and then the marking rod 4 in the cavity 21 is inserted downward to the boundary point through the clamping and transferring mechanism 5. At this time, the guide pushing mechanism 6 continues to clamp and guide the inserted marking rod 4, and then the surveyor inserts multiple marking rods 4 into the boundary of the land to be measured in turn according to needs, and marks the inserted marking rods 4, and then the infrared rangefinder on the top of the box 2 3 is opened, and then the infrared rangefinder 3 is driven to rotate by rotating the lifting mechanism 8, so that it corresponds to the reflective component 41 or the receiving unit on the inserted marking rod 4 in turn, and then the infrared rangefinder 3 will measure the area, length or width of the land to be evaluated according to the infrared rays emitted and reflected and received, so as to improve the accuracy and efficiency of land evaluation measurement, and the infrared rangefinder 3 and the reflective component 41 are both moved and inserted on the land to be measured by the mobile vehicle 1, so there is no need for the operator to manually insert the marking rod 4, so as to reduce the labor intensity of the surveyor, and the accuracy of the measurement will not be affected by the complexity of the land to be measured, and when the land measurement is completed, the mobile vehicle 1 moves to multiple inserted marking rods 4 in turn, and then through the cooperation of the clamping transfer mechanism 5 and the guide pushing mechanism 6, the inserted marking rod 4 is pulled out from the land and placed in the cavity of the box body 2, and then the sealing door 9 is inserted into the cavity 21 through the sealing strip, so as to facilitate the mobile vehicle 1 to drive multiple marking rods 4 to be transferred to the next plot to be measured for land evaluation measurement.

[0022] In the design of the present invention, the clamping and transferring mechanism 5 includes a screw member 51, which is rotatably installed in the cavity 21, and a ball nut is sleeved on the screw member 51, and two supporting long plates 52 are fixed on the ball nut, a shaft member 53 is vertically rotatably installed on one side of the screw member 51, and a guide long strip 54 is formed on the shaft member 53, and a sleeve 55 is sleeved on the shaft member 53, a key groove that cooperates with the guide long strip 54 is formed inside the sleeve 55, and the sleeve 55 is connected to the upper and lower supporting long plates 52 through a bearing, a support block 56 is connected to the sleeve 55, and a first electric clamp 57 is fixed on the outer end surface of the support block 56, and a guide support plate 58 is fixed on the upper and lower surfaces of the support block 56, and the first electric clamp 57 is located between the two guide support plates 58, an electric push rod 59 is fixed on one side of the support block 56, and the output rod of the electric push rod 59 is connected to the cylinder body of the first electric clamp 57; Specifically, when it is necessary to take the marking rod 4 out of the cavity 21 and insert it into the boundary point, the output rod of the electric push rod 59 fixed on the outer side of the support block 56 is first controlled to extend, so that it pushes the first electric clamp 57 to slide between the upper and lower guide support plates 58 toward the marking rod 4, and the opened clamps will be located on both sides of the marking rod 4, and then the first electric clamp 57 will work to clamp the marking rod 4, and then the output rod of the electric push rod 59 will be recovered, so that the clamped marking rod 4 will slowly slide out of the cavity, and then the servo motor connected to the bottom of the shaft member 53 will be controlled to work. At this time, the rotation of the shaft member 53 will drive the guide strip 54 and the key groove to cooperate. The sleeve 55 rotates, and the rotation of the sleeve 55 drives the first electric clamp 57 to rotate through the support block 56, so that the clamped marking rod 4 will rotate to the outside of the cavity 21, and then the servo motor connected to the bottom of the screw member 51 is controlled to work, so that it drives the vertical screw member 51 to rotate, and then the ball nut drives the sleeve 55 to slide downward along the shaft member 53 through the upper and lower supporting long plates 52. At this time, the shaft member 53 can act as a vertical guide rod, so that the marking rod 4 extending out of the cavity 21 moves downward, and then through the cooperation of the guide push mechanism 6, the marking rod 4 can be stably and safely inserted into the boundary point, and the above steps are repeated in sequence to put the marking rod 4 into the cavity 21. 4 is inserted into the soil of the land stably and quickly to achieve stable support for the reflective component 41; and when it is necessary to remove the measured marker rod 4 from the boundary point, the mobile vehicle 1 moves to the marker rod 4, and the first electric clamp 57 moves down to the bottom of the cavity 21, and then the output rod of the electric push rod 59 is extended to make the opened clamp located at the marker rod 4, and then the first electric clamp 57 clamps and fixes the marker rod 4, and then the rotation of the lead screw 51 will drive the sleeve 55 to slide upward along the shaft rod 53 through the supporting long plate 52, and then the rise of the first electric clamp 57 will drive the clamped marker rod 4 to be taken out of the soil, and when the marker rod 4 rises to the position aligned with the cavity 21, the marker rod 4 is removed from the soil. After the cavity opening is flush, the output rod of the electric push rod 59 on the side of the support block 56 is retracted, so that the first electric clamp 57 drives the clamped marking rod 4 to move to the cavity opening of the cavity 21, and then the rotation of the shaft member 53 will drive the first electric clamp 57 to rotate through the sleeve 55, the support block 56 and the guide support plate 58, so that the marking rod 4 can be transferred to the cavity 21 for storage. By repeating the above steps in sequence, the multiple marking rods 4 inserted into the soil can be retracted into the box 2 for storage, and there is no need for the surveyor to manually insert and retract the marking rod 4, so that the marking rod 4 can be stably and safely inserted into the soil of the land for auxiliary measurement.

[0023] In the design of the present invention, the guide push mechanism 6 includes a second electric clamp 61, which is fixed at the bottom of the box body 2, and the clamping claw 62 of the second electric clamp 61 is an L-shaped structure, the L-shaped clamping claw 62 is connected with a clamping block 63 through a spring member 64, the bottom of the clamping block 63 is slidably connected with a T-shaped slide groove provided on the clamping claw 62 through a T-shaped slider, and a capsule column 65 is connected between the back of the clamping block 63 and the clamping claw 62, a conduit member 66 is fixed in the middle of the cylinder body of the second electric clamp 61, and a sliding rod 67 is slidably inserted in the conduit member 66, the bottom of the conduit member 66 is connected with the capsule column 65 through an air pipe, and a push column 68 is installed at the outer end of the sliding rod 67; Specifically, the cylinder of the second electric clamp 61 is fixedly installed in the cavity formed between the box body 2 and the chassis of the mobile vehicle 1, and the extended length of the symmetrical clamp block 63 is aligned with the clamp of the first electric clamp 57 after rotation. Therefore, when the first electric clamp 57 moves the clamped marking rod 4 to the outside of the cavity 21 and aligns the bottom of the marking rod 4 with the opened clamp block 63, the downward movement of the marking rod 4 will cause the bottom end of the marking rod 4 to be inserted between the symmetrical clamp blocks 63, and then the second electric clamp 61 is controlled. The clamping claws 62 slide towards each other, and the clamping claws 62 will drive the symmetrical clamping blocks 63 to slide towards each other and fit onto the marking rod 4 through the spring members 64, so that the marking rod 4 continues to move downward. At this time, the contacting clamping blocks 63 will play an auxiliary guiding role for the downward moving marking rod 4, so that the marking rod 4 can be inserted into the soil in a vertical state. When the insertion of the marking rod 4 is completed, the two electric clamps work synchronously, so that the clamping claws 62 slide away from each other synchronously, and then the clamping blocks 63 will lose contact with the marking rod 4.

[0024] In the design of the present invention, the marking rod 4 includes an upper conduit 42, in which a lower insert tube 43 is slidably connected via a spring, and a reflective component 41 is installed on the top of the upper conduit 42, a plurality of buckle holes 44 are provided on the tube wall of the upper conduit 42, and both ends of the lower insert tube 43 are sealed, and a strip-shaped notch is formed on its tube wall, a push strip 45 is slidably provided in the strip-shaped notch, the inner wall of the push strip 45 is connected to the tube wall of the lower insert tube 43 via a spring member 64, and the bottom end of the push strip 45 is elastically sealed and connected to the bottom of the groove of the strip-shaped notch, a protruding column 46 is fixedly provided on the outer side of the top of the push strip 45, and the protruding column 46 and the buckle hole 44 are plugged and matched with each other, and the push strip 45 corresponds to the push column 68; Specifically, in order to prevent the marker rod 4 from being inserted into the soil and the reflective component 41 from being too low in height, causing the infrared rangefinder 3 to be unable to accurately correspond to the reflective component 41, thereby affecting the accuracy of the land assessment measurement, when the marker rod 4 needs to be transferred and inserted from the cavity 21, the clamping jaws of the first electric clamp 57 will clamp onto the upper guide tube 42, and the multiple snap holes 44 on the upper guide tube 42 will face the cylinder direction of the first electric clamp 57. At this time, the push strip 45 will be pushed by the elastic thrust of the internal spring member 64, causing the raised column 46 on the top side to be stuck in the snap hole 44. At this time, the lower insert tube 43 will be in a fixed state in the upper guide tube 42, and then the first electric clamp 57 will drive the marker rod 4 of a fixed length to be transferred to the outside of the cavity 21, and Make the lower insert tube 43 correspond to the symmetrical clamping block 63. At this time, the first electric clamping jaw 57 descends along the shaft member 53, which will cause the lower insert tube 43 to move downward between the symmetrical clamping blocks 63. At this time, if it is necessary to increase the length of the marking rod 4 and make the reflecting component 41 correspond to the infrared rangefinder 3, it is necessary to first control the clamping jaws 62 of the second electric clamping jaw 61 to move closer to each other, so that the symmetrical clamping blocks 63 first clamp and fix the lower insert tube 43, and then the clamping jaws of the first electric clamping jaw 57 are disengaged from the clamping of the upper guide tube 42, and then continue to control the clamping jaws 62 of the second electric clamping jaw 61 to slide closer to each other. At this time, the movement of the clamping jaws 62 will squeeze the capsule column 65. At this time, the spring member 64 will be in a compressed state, and the T-shaped slider will slide relatively in the T-shaped slide groove, so that the capsule column 65 can be moved downward. The gas in the column 65 will enter the conduit member 66 through the soft air tube, so that the sealed inserted sliding rod 67 will extend from the conduit member 66. At this time, the spring member 64 in the conduit member 66 will be stretched, and the extension of the sliding rod 67 will push the pushing column 68 to squeeze the push strip 45. At this time, the push strip 45 will move toward the lower insert tube 43, and the spring member 64 connected to the push strip 45 will be compressed, and then the movement of the push strip 45 will drive the protruding column 46 to disengage from the buckle hole 44, and then the spring member 64 connected in the upper conduit 42 will push it to move upward, thereby increasing the overall length of the marking rod 4. When the marking rod 4 grows to a certain length, the clamping claws 62 of the second electric clamp 61 are controlled to slowly slide away from each other, and the clamping block 63 The spring member 64 connected to the clamping claw 62 will continue to push the clamping block 63 to clamp and fix the lower insert tube 43, and the clamping claw 62 that slides away will restore the compressed sac column 65, so that the gas in the catheter member 66 is withdrawn, and at this time, the spring member 64 in the catheter member 66 will pull the sliding rod 67 to recover, and then the pushing column 68 will be separated from the squeezing of the push strip 45, and then the spring member 64 in the lower insert tube 43 will push the push strip 45 to move outward, so that the protruding column 46 continues to be inserted into the aligned buckle hole 44, so as to fix the extended marking rod 4, and then control the clamping claw of the first electric clamping claw 57 to clamp and fix the extended marking rod 4, and then make the symmetrical clamping claws 62 continue to move away from each other, so that the symmetrical clamping blocks 63 only contact the marking rod 4,Then, the downward movement of the first electric clamp 57 will drive the growing marking rod 4 to be accurately and stably inserted into the soil, so that the marking rod 4 can support the reflective component 41 with different lengths, thereby further improving the accuracy and efficiency of the correspondence between the infrared rangefinder 3 and the reflective component 41; When it is necessary to shorten the initial length of the drawn marking rod 4 so that it can be accurately recovered into the cavity 21, the upper guide tube 42 is first clamped and fixed by the first electric clamp 57, and then the first electric clamp 57 rises to pull the marking rod 4 out of the soil. After the lower insert tube 43 moves between the symmetrical clamping blocks 63, the symmetrical clamping blocks 63 clamp and fix the lower insert tube 43, and then the push column 68 moves to push the push strip 45 to disengage the protruding column 46 from the buckle hole 44, and then the first electric clamp 57 continues to clamp the upper guide tube 42 and move downward, so that the lower insert tube 43 slides into the upper guide tube 42. At this time, the spring member 64 inside the upper guide tube 42 is in a compressed state. State, and then when the distance from the bottom of the lower insert tube 43 to the top of the upper guide tube 42 reaches the appropriate length, the push column 68 is reset, so that the push strip 45 is reset and drives the protruding column 46 to be inserted into the corresponding buckle hole 44, thereby fixing the reduced lower insert tube 43 and the upper guide tube 42, and then the clamping block 63 is disengaged from the clamping fixation of the lower insert tube 43, and the rise of the first electric clamp 57 will continue to clamp the marking rod 4 and move it upward, so that the bottom of the marking rod 4 is flush with the bottom of the cavity 21, and then the rotation of the first electric clamp 57 will drive the clamped marking rod 4 to rotate into the cavity 21, thereby facilitating the marking rod 4 pulled out of the soil to be quickly and safely stored in the box body 2.

[0025] In the design of the present invention, a hidden cavity 22 is opened to the left on the front side wall of the cavity 21, and a push mechanism 7 is arranged in the hidden cavity 22, and the push mechanism 7 includes an end support block 71, a lead screw 51 is rotatably installed in the hidden cavity 22, and the outer end of the lead screw 51 is connected to the fixed end support block 71 through a bearing, a guide support block 72 is sleeved on the lead screw 51 through a ball nut, and a U-shaped clamping block 73 is installed on the outer side of the guide support block 72, and a U-shaped clamping groove 731 is opened on the U-shaped clamping block 73, an annular cavity is formed inside the guide support block 72, and an electromagnetic suction ring 74 is insulated and installed in the annular cavity, a metal ring 75 is insulated and sleeved on the ball nut, and the metal ring 75 is in contact with the electromagnetic suction ring 74; The U-shaped clamping block 73 is made of elastic rubber material, so that the upper guide tube 42 slides and is clamped in the U-shaped clamping groove 731, and then the electromagnetic suction block on the inner ring surface of the electromagnetic suction ring 74 inside the guide support block 72 is energized to adsorb and fix the metal ring 75, so that the guide support block 72 is fixedly connected to the ball nut, while the other guide support blocks 72 continue to be disconnected from the other ball nuts, and then the lead screw 51 supported on the end support block 71 will be rotated by the drive of the servo motor, and then the guide support block 72 will drive the marking rod 4 clamped by the side U-shaped clamping block 73 to slide into the hidden cavity 22, and then the above steps are repeated in sequence, so that multiple marking rods 4 can be stacked in the box body 2 at equal distances in sequence; and when the marking rod 4 needs to be transferred and taken out from the box body 2, the first electric clamping The claw 57 will clamp and transfer the first marking rod 4 located at the head of the hidden cavity 22, and then the rotation of the screw member 51 will drive the first free guide support block 72 and the U-shaped block 73 to slide toward the end support block 71, and at this time the screw member 51 will drive the subsequent marking rod 4 engaged on the U-shaped block 73 to slide to align with the clamping claw of the first electric clamp 57. When the first guide support block 72 slides to the side limit distance of the end support block 71, the electromagnetic suction block on the inner ring surface of the electromagnetic suction ring 74 is powered off, and The detachment from the adsorption and fixation of the metal ring 75 and the continued rotation of the lead screw 51 will only drive the subsequent marking rod 4 to move to a position aligned with the first electric clamp 57, and the distance between the end support block 71 and the shaft rod 53 will not affect the storage space for multiple guide support blocks 72 after sliding forward, and the inner side surface of the guide support block 72 is in frictional contact with the cavity wall of the hidden cavity 22, so that the ball nut detached from the inside of the guide support block 72 will only rotate freely, and will not drive the guide support block 72 to continue sliding.

[0026] In the design of the present invention, the infrared rangefinder 3 is installed on the top of the box body 2 through a rotating lifting mechanism 8. The rotating lifting mechanism 8 includes a rotating shaft tube 81.
