[0012] Preferably, a protective component is installed below the mounting sleeve, and the protective component includes two upper and lower annular protrusions and a protective cover. The inner wall of the annular protrusion is fixedly connected to the lower driving end of the dual-axis motor, and the lower driving end of the dual-axis motor passes through the protective cover. The outer wall of the protective cover is fixedly connected to a limiting rod, and the top end of the limiting rod passes through the mounting sleeve.

[0013] Preferably, the protective component also includes a supporting elastic member and a mounting ring, the supporting elastic member is sleeved on the outer side of the lower driving end of the dual-axis motor, the inner wall of the mounting ring is slidably connected to the lower driving end of the dual-axis motor, and scrapers are fixedly connected to both sides of the mounting ring.

[0014] Preferably, a limit block is fixedly connected to the lower side wall of the leg body, the limit block is set to be a triangle, and a moving wheel is fixedly provided on the lower side wall of the leg body.

[0015] Working principle: Install the land resource surveying and mapping equipment on the mounting base to survey the land resources. When the surveying and mapping equipment is used on solid ground or rocky ground, press the mounting base downward to compress the leg body, so that the drill bit moves down and presses against the ground. The dual-axis motor is controlled by the controller to operate, and the lower driving end of the dual-axis motor drives the drill bit to rotate to drill holes on the hard ground or rocky ground. The drill bit is inserted into the ground to provide stable support and positioning for the device. When the dual-axis motor drives the drill bit to drill holes, it also drives the leg body to rotate and unfold, thereby improving the stability of the support. After use, the drill bit is driven to rotate in the opposite direction by the reverse operation of the dual-axis motor, so that the drill bit exits the drilling hole and the device can be moved.

[0016] Before drilling, close the lower air outlet end, and the threaded ring will push the seal to move downward when it descends. The seal pushes the air in the space below the piston cylinder to be discharged through the one-way valve. When the threaded ring descends to the lowest point, outside air cannot enter the space below the piston cylinder, so that the space below the piston cylinder remains relatively sealed. The seal is limited by the pressure difference, so that the seal is disconnected from the threaded ring, so as to avoid the cyclic rise and fall of the seal during drilling, reduce wear and extend the service life of the seal. At the same time, when drilling, the leg body will not shrink again after being unfolded. When the device needs to store the leg body after use, open the valve to allow outside air to enter the piston cylinder through the lower air outlet end, so that the seal can rise, and the threaded ring is driven to rotate by the upper driving end of the dual-axis motor, so that the threaded ring first descends to the bottom end of the reciprocating screw, and is attracted to the iron ring by the magnetic ring, and then rises to the top of the reciprocating screw. When the threaded ring rises, it drives the seal to rise, and the rising seal pulls the leg body to rotate inward through the bracket, thereby storing the leg body. Before drilling, the air outlet channel is opened so that it is connected to the outside world. When the outrigger body is compressed, the air inside the upper connecting tube can be discharged, thereby realizing the normal extension and contraction of the outrigger body. After the drilling is completed, the sealing head blocks the air outlet channel, thereby closing the upper connecting tube. The pressure difference allows the outrigger body to maintain a fixed extension distance, thereby realizing stable support.

[0017] When it is used on a flat ground, the reciprocating screw is driven to rotate by the driving end of the dual-axis motor, and the reciprocating screw drives the threaded ring to move downward, and the threaded ring pushes the seal to move. The movement of the seal pushes the air under the piston cylinder to be discharged through the one-way valve. When the threaded ring moves to the bottom end of the reciprocating screw, the controller controls the dual-axis motor to stop running. After the threaded ring drives the seal to descend, the support leg body is pushed to rotate and unfold to press against the ground through the bracket, which is convenient for the device to be used on a flat ground. When supported by the support leg body, the height of the support leg body can be adjusted by pressing, and the air outlet channel can be blocked by the sealing head so that the support leg body maintains a fixed extension distance, thereby adjusting the length of the support leg body and adjusting the height of the mounting seat.

[0018] The supporting elastic member applies thrust to the protective cover so that the protective cover is tightly pressed against the ground to avoid a large gap that affects the interception effect of debris. After use, the protective cover is pressed against the lower annular protrusion by the elastic force of the supporting elastic member, thereby remaining on the outside of the drill bit, which plays a certain protective effect. When drilling, the protective cover drives the mounting ring to rise and fall, and the dual-axis motor drives the mounting ring to rotate when it is running. The rotation of the mounting ring drives the scraper to rotate, and the rotation of the scraper automatically cleans the inner wall of the protective cover, thereby reducing the adhesion and residue of debris on the inner wall of the protective cover, which plays an effect of automatically cleaning the protective cover. When the device needs to be moved, the support leg body is first stored and compressed to reduce the length, so that the moving wheel can press against the ground when the device is tilted, and then the device is rotated to make the moving wheel press against the ground, which is convenient for the operator to pull the device to move.

[0019] The present invention provides a land resource surveying and planning locator. It has the following beneficial effects: 1. The present invention drives the drill bit to rotate through a dual-axis motor to drill holes on hard ground or rocky ground. The drill bit is inserted into the ground to provide stable support and positioning for the device, making it easy to use the device on solid ground or rocky ground.

[0020] 2. The present invention achieves multiple functions such as drilling and extension and storage of the leg body through a dual-axis motor, realizing multifunctional application of a single device and realizing more functional applications with minimal investment in structure and equipment.

[0021] 3. The present invention limits the seal by pressure difference, so that the seal is disconnected from the threaded ring, avoiding the seal from cyclically rising and falling during drilling, reducing wear and tear, and extending the service life of the seal.

[0022] 4. The present invention protects the drill bit through the protective cover, and the protective cover is closed on the ground during drilling, so as to intercept the debris splashed during drilling and prevent the debris from splashing onto nearby operators.

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.

[0026] Please refer to the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a land resource surveying and mapping planning locator, including a mounting seat 1, a leg assembly 7 is installed on the lower surface of the mounting seat 1, and the leg assembly 7 includes a retractable leg body 71, the top of the leg body 71 is rotatably mounted on the lower surface of the mounting seat 1 through a torsion spring shaft, and a torsion force is applied to the leg body 71 toward the piston cylinder 2 through the torsion spring shaft, so that the leg body 71 maintains a storage state in the initial state, and the bottom of the mounting seat 1 is fixedly connected to the piston cylinder 2, and the bottom end of the piston cylinder 2 is fixedly connected to the mounting sleeve 3 through a connecting rod, and the inner wall of the mounting sleeve 3 is fixed A dual-axis motor 4 is connected, and a drill bit 5 is fixedly connected to the lower driving end of the dual-axis motor 4. A lifting and lowering adjustment component 6 is installed inside the piston cylinder 2. The lifting and lowering adjustment component 6 includes a reciprocating screw 61 and a one-way valve 62. The bottom end of the reciprocating screw 61 is fixedly connected to the upper driving end of the dual-axis motor 4, and the outer wall of the reciprocating screw 61 is threadedly connected with a threaded ring 68. A sealing member 67 is installed below the threaded ring 68. The top of the threaded ring 68 is fixedly connected with a guide rod 64, and the guide rod 64 passes through the mounting seat 1. The one-way valve 62 is fixedly arranged on the lower side wall of the piston cylinder 2, and the bottom of the sealing member 67 is fixedly connected to the lower side wall of the piston cylinder 2. The end is rotatably connected with a bracket 69, and the bottom end of the bracket 69 is rotatably connected with the outer wall of the leg body 71. A power module is fixedly arranged inside the mounting seat 1, and the power module is used to power the device. A controller is fixedly arranged on the outer wall of the mounting seat 1. The controller is electrically connected to the dual-axis motor 4 and the power module. The controller controls the operation of the dual-axis motor 4. The dual-axis motor 4 adopts a high-precision servo motor or a stepper motor to achieve precise control of the moving position of the threaded ring 68. When the accuracy of the dual-axis motor 4 is not high, a distance measuring sensor can be fixedly arranged on the lower surface of the mounting seat 1 for monitoring. The position of the threaded ring 68 is measured, and the distance measuring sensor is electrically connected to the controller. The distance measuring sensor measures the distance to the threaded ring 68, and the lifting height of the threaded ring 68 is monitored. When the predetermined height is reached, the distance measuring sensor transmits a signal to the controller, and the controller controls the dual-axis motor 4 to stop running, thereby accurately controlling the lifting height of the threaded ring 68. The seal 67 passes through the piston cylinder 2, and a sealing structure is fixedly provided at the intersection of the bottom end of the piston cylinder 2 and the seal 67 for sealing. The sealing structure can adopt sealing methods such as labyrinth seals, mechanical seals, and rubber oil seals.

[0027] Specifically, a mounting hole for connecting the land resource surveying and mapping equipment is reserved on the upper surface of the mounting seat 1. The one-way valve 62 is used to control the one-way outflow of the internal gas of the air piston cylinder 2 from the one-way valve 62. The mounting seat 1 is used to install the land resource surveying and mapping equipment. When it is used on a flat ground, the reciprocating screw 61 is driven to rotate by the driving end of the double-axis motor 4. The reciprocating screw 61 drives the threaded ring 68 to move downward. The threaded ring 68 pushes the seal 67 to move. The movement of the seal 67 pushes the air under the piston cylinder 2 to be discharged from the one-way valve 62. When the threaded ring 68 moves to the bottom end of the reciprocating screw 61, the controller controls the double-axis motor 4 to stop running. After the threaded ring 68 drives the seal 67 to descend, the support 69 is pushed The leg body 71 rotates and unfolds to press against the ground, which makes it easy to use the device on flat ground. When using it on solid ground or rocky ground, press the mounting base 1 downward to compress the leg body 71, so that the drill bit 5 moves down and presses against the ground. The dual-axis motor 4 is controlled by the controller to operate, and the lower driving end of the dual-axis motor 4 drives the drill bit 5 to rotate to drill holes in the hard ground or rocky ground. The drill bit 5 is inserted into the ground to provide stable support and positioning for the device. When the dual-axis motor 4 drives the drill bit 5 to drill holes, it also pushes the leg body 71 to rotate and unfold, thereby improving the stability of the support. After use, the drill bit 5 is driven to rotate in the opposite direction by the reverse operation of the dual-axis motor 4, so that the drill bit 5 exits the drilling hole and the device can be moved.

[0028] Please see attached Figure 3 The top of the sealing member 67 is fixedly connected with the iron ring 12 , and the lower surface of the threaded ring 68 is fixedly connected with the magnetic ring 65 .

[0029] Specifically, the magnetic ring 65 absorbs the iron ring 12 so that the threaded ring 68 can magnetically absorb the sealing member 67 , thereby driving the sealing member 67 to rise when the threaded ring 68 rises.

[0030] Please see attached Figure 3 -Attached Figure 4 The lifting and lowering adjustment component 6 also includes an upper air outlet end 66 and a lower air outlet end 63. The upper air outlet end 66 is fixedly arranged on the upper side wall of the piston cylinder 2, and the lower air outlet end 63 is fixedly arranged on the lower side wall of the piston cylinder 2. A valve is installed on the lower air outlet end 63. The valve can be a solenoid valve and is electrically connected to the controller to realize automatic control of the valve and reduce manual operation.

[0031] Specifically, the upper space of the piston cylinder 2 is connected to the outside world through the upper air outlet end 66. When the leg body 71 is unfolded or used for drilling, the lower air outlet end 63 is closed, and the threaded ring 68 pushes the seal 67 to move downward when it descends. The seal 67 pushes the air in the space below the piston cylinder 2 to be discharged through the one-way valve 62. When the threaded ring 68 descends to the lowest point, the outside air cannot enter the space below the piston cylinder 2, so that the space below the piston cylinder 2 remains relatively sealed. The seal 67 is limited by the pressure difference, so that the seal 67 is disconnected from the threaded ring 68, so that the seal 67 is prevented from cyclically rising and falling when drilling, thereby reducing wear and extending the service life of the seal 67. At the same time, when drilling, the leg body 71 will not shrink after being unfolded. When the device needs to store the leg body 71 after use, the valve is opened to allow the outside air to enter. The boundary air enters the piston cylinder 2 through the lower air outlet end 63, so that the seal 67 can rise, and the threaded ring 68 is driven to rotate by the driving end on the dual-axis motor 4, so that the threaded ring 68 first drops to the bottom end of the reciprocating screw 61, and absorbs the iron ring 12 through the magnetic ring 65, and then rises to the top of the reciprocating screw 61. When the threaded ring 68 rises, it drives the seal 67 to rise. The seal 67 rises and pulls the leg body 71 to rotate inward through the bracket 69, thereby storing the leg body 71. The torsion of the torsion spring shaft and the magnetic attraction effect of the magnetic ring 65 and the iron ring 12 can realize relatively stable storage of the leg body 71. The device achieves multiple functions such as drilling and stretching and storing the leg body 71 through the dual-axis motor 4, realizes the multi-functional application of a single device, and realizes more functional applications with minimal investment in structure and equipment.

[0032] Please refer to the attached Figure 4 The guide rod 64 includes a rod body 642 , a top end of the rod body 642 is fixedly connected to a cylinder body 641 , and an outer wall of the cylinder body 641 is fixedly connected to the mounting seat 1 .

[0033] Specifically, the guide rod 64 is used to limit the threaded ring 68 so that the threaded ring 68 moves vertically along the bidirectional lead screw. When the threaded ring 68 is lifted or lowered, it drives the rod body 642 to be lifted or lowered inside the cylinder body 641 .

[0034] Please refer to the attached Figure 4 An opening is provided at the center of the sealing member 67 , and the sealing member 67 includes an I-shaped sealing ring 671 , and a T-shaped connecting end 672 is fixedly connected to the bottom end of the sealing ring 671 .

[0035] Specifically, the opening is used for the reciprocating screw 61 and the driving end of the dual-axis motor 4 to pass through the seal 67, the sealing ring 671 is used to separate the inside of the piston cavity into two upper and lower spaces, and the connecting end 672 is used to extend the length of the seal 67 so as to connect it to the bracket 69 on the outside of the piston cylinder 2.

[0036] Please refer to the attached Figure 5 -Attached Figure 6A plurality of air outlet channels 74 are provided inside the mounting base 1. The leg body 71 includes an upper connecting tube 711 and a lower supporting rod 712. The top end of the lower supporting rod 712 is slidably installed inside the upper connecting tube 711. A clamping elastic member 713 is provided inside the upper connecting tube 711. The clamping elastic member 713 is made of a fatigue-resistant spring or a memory alloy. A connecting pipe 714 is fixedly connected to the upper side wall of the upper connecting tube 711. The other end of the connecting pipe 714 is connected to the air outlet channel 74. A piston block is fixedly provided on the top end of the lower supporting rod 712. The clamping elastic member 713 is located above the piston block. The piston block is used to separate the upper connecting tube 711.

[0037] Specifically, the lower support rod 712 slides downward by the elastic force of the compression elastic member 713 , so that the leg body 71 remains extended, and the connecting pipe 714 is used to connect the upper connecting tube 711 with the air outlet channel 74 .

[0038] Please see attached Figure 7 The leg body 71 also includes a rotating ring 78 and a plurality of limiting protrusions 79. The outer wall of the mounting seat 1 is tapped with a thread. The inner wall of the rotating ring 78 is threadedly connected to the outer wall of the mounting seat 1. A connecting ring 76 is rotatably connected to the lower side wall of the rotating ring 78. A limiting groove is provided on the outer wall of the mounting seat 1. The inner wall of the rotating ring 78 is inserted into the limiting groove. The inner wall of the connecting ring 76 is slidably connected to the outer wall of the mounting seat 1. A plurality of sealing heads 77 are fixedly connected to the bottom end of the connecting ring 76. The position and quantity of the air outlet channel 74 and the sealing head 77 are kept consistent. A rubber sealing sleeve is fixedly provided on the outer wall of the sealing head 77 to improve the sealing effect. The limiting protrusion 79 is fixedly installed on the lower side wall of the mounting seat 1. The limiting protrusion 79 is located on the outer side of the upper connecting tube 711.

[0039] Specifically, the limiting protrusion 79 is used to limit the rotation angle of the upper connecting tube 711. The sealing member 67 drops to the lowest position and pushes the upper connecting tube 711 to rotate and unfold. At this time, the outer wall of the upper connecting tube 711 abuts against the bottom end of the limiting protrusion 79 to prevent the leg body 71 from further unfolding. When the leg body 71 is restricted, the position of the sealing member 67 is also limited, so that the sealing member 67 cannot continue to move downward, and the pressure difference prevents the sealing member 67 from moving upward, so that the position of the sealing member 67 does not change, and the stability of the leg body 71 when the support is unfolded is maintained. The upper connecting tube 71 can be connected to the outside world through the air outlet channel 74, and the rotating ring 78 is raised and lowered along the mounting seat 1 by screwing. The lifting of the rotating ring 78 drives the connecting ring 76 to lift, and the lifting of the connecting ring 76 drives the sealing head 77 to lift. When the sealing head 77 drops to the lowest point, it is inserted into the air outlet channel 74, thereby closing the air outlet channel 74. When the sealing head 77 moves upward, the air outlet channel 74 is opened. Before drilling, the air outlet channel 74 is opened to connect the air outlet channel 74 to the outside world, so that when the support leg body 71 is compressed, the air inside the upper connecting tube 711 can be discharged, thereby realizing the normal extension and contraction of the support leg body 71. After the drilling is completed, the sealing head 77 blocks the air outlet channel 74, thereby closing the upper connecting tube 711, and the pressure difference is used to keep the support leg body 71 at a fixed extension distance, thereby realizing stable support. When supporting by the support leg body 71, the height of the support leg body 71 can be adjusted by pressing, and the air outlet channel 74 can be blocked by the sealing head 77 to keep the support leg body 71 at a fixed extension distance, thereby adjusting the length of the support leg body 71 and realizing the adjustment of the height of the mounting base 1.

[0040] Please see attached Figure 8 -Attached Fig. 9 A protective component 9 is installed below the mounting sleeve 3. The protective component 9 includes two upper and lower annular protrusions 91 and a protective cover 92. The inner wall of the annular protrusion 91 is fixedly connected to the lower driving end of the dual-axis motor 4. The lower driving end of the dual-axis motor 4 passes through the protective cover 92. The outer wall of the protective cover 92 is fixedly connected to a limiting rod 93. The top end of the limiting rod 93 passes through the mounting sleeve 3.

[0041] Specifically, the protective cover 92 is limited by the annular protrusion 91, and the limiting rod 93 is used to limit the moving direction of the protective cover 92. When the drill bit 5 drills deep into the ground, the protective cover 92 covers the ground, thereby intercepting the debris splashed during drilling and preventing the debris from splashing onto nearby operators.

[0042] Please see attached Fig. 9The protection component 9 also includes a supporting elastic member 94 and a mounting ring 95. The supporting elastic member 94 is sleeved on the outer side of the lower driving end of the dual-axis motor 4. The supporting elastic member 94 adopts a fatigue-resistant spring or memory alloy. A limiting groove is provided on the outer side of the lower driving end of the dual-axis motor 4. The inner wall of the mounting ring 95 is inserted into the inner part of the limiting groove. The inner wall of the mounting ring 95 is slidably connected to the lower driving end of the dual-axis motor 4. Scrapers 96 are fixedly connected to both sides of the mounting ring 95.

[0043] Specifically, the protective cover 92 is applied with thrust by the supporting elastic member 94 so that the protective cover 92 is tightly pressed against the ground to avoid a large gap and affect the interception effect of debris. After use, the protective cover 92 is pressed against the lower annular protrusion 91 by the elastic force of the supporting elastic member 94, thereby being kept on the outside of the drill bit 5, and having a certain protective effect. When drilling, the protective cover 92 drives the mounting ring 95 to rise and fall, and the dual-axis motor 4 drives the mounting ring 95 to rotate when it is running. The rotation of the mounting ring 95 drives the scraper 96 to rotate, and the rotation of the scraper 96 automatically cleans the inner wall of the protective cover 92, thereby reducing the adhesion and residue of debris on the inner wall of the protective cover 92, and having the effect of automatically cleaning the protective cover 92.

[0044] Please refer to the attached Figure 8 The lower side wall of the leg body 71 is fixedly connected to a limit block 10, and the limit block 10 is set to a triangle. The lower side wall of the leg body 71 is fixedly provided with a moving wheel 11, and the upper side wall of the mounting seat 1 is fixedly provided with a handle.

[0045] Specifically, the limit block 10 is used to abut against the protective cover 92 when the leg body 71 is retracted and extended to the maximum extent and the air outlet channel 74 is closed, so as to fix the position of the protective cover 92 so that the drill bit 5 remains inside the protective cover 92, thereby preventing the drill bit 5 from colliding with external objects, thereby preventing the drill bit 5 from being damaged or accidentally injuring the operator, thereby improving the safety of the device. When the device needs to be moved, the leg body 71 is first retracted and compressed to reduce the length so that the moving wheel 11 can abut against the ground when the device is tilted, and then the device is rotated so that the moving wheel 11 abuts against the ground, which is convenient for the operator to pull the device to move.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
