Description

Technical Field

[0001] The present invention relates to the technical field of positioning equipment, in particular to an energy-saving positioning device for mine foundation engineering. Background Art

[0002] The foundation refers to the soil or rock supporting the building's foundation. The soil layers serving as the building's foundation are divided into rock, gravel soil, sandy soil, and artificial fill, etc. At the same time, the foundation is divided into natural foundation and artificial foundation. When constructing a building, the foundation is the most basic and most important step.

[0003] The patent with patent announcement number CN218624079U discloses a positioning device for foundation engineering, including a base plate, four sliding rods are fixedly provided on the top of the base plate, a top plate is fixedly provided on the top of the four sliding rods, and the same guide plate is movably provided on the four sliding rods, and a plurality of push rod motors are fixedly provided at the bottom of the top plate, and the output ends of the plurality of push rod motors are fixedly connected to the top of the guide plate, and a driving motor and a battery are provided on the top of the guide plate, and a connecting sleeve is fixedly provided at the output end of the driving motor, and a drill bit is provided in the connecting sleeve, and a limiting structure is provided on the top of the base plate. This patent provides components such as push-pull handles, base plate, sliding rods, top plate, driving motor and drill bit. When positioning the foundation, the equipment can be moved to the location to be positioned, and the driving motor can be started to perform drilling positioning. There is no need to transport the equipment to the construction site, and manual operation is required, saving time and effort.

[0004] However, this device still has some shortcomings: the device can be moved with little effort and perform drilling positioning, but when the drill bit rotates at high speed and comes into contact with fine gravel on the ground, the centrifugal force of the high-speed rotation can easily cause the gravel to splash around. The splashing gravel can easily cause certain injuries to the surrounding workers, reducing construction safety to a certain extent. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides an energy-saving mine foundation engineering positioning device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An energy-saving positioning device for mine foundation engineering, comprising a bottom plate. Support rods are fixedly installed at the corners of the top of the bottom plate. A top plate is fixedly installed at the top of the support rods. A driving mechanism is arranged at the center of the top of the top plate. The bottom of the output end of the driving mechanism on the top plate penetrates and is fixedly installed with an electric telescopic rod. A drill bit is fixedly installed at the bottom of the telescopic end of the electric telescopic rod. A pressing plate is fixedly installed on the outer wall of the telescopic end of the electric telescopic rod. A protective plate is penetrated and slidably installed through a spring inside the rectangular groove of the bottom plate. An anti-load device for rapid ventilation is arranged inside the protective plate. A marking device for marking the positioning point is arranged around the anti-load device. A fixing plate is fixedly installed on the outer wall of the protective plate. A threaded nail is rotatably installed at the bottom of the fixing plate. A number of limiting plates are symmetrically and fixedly installed on the bottom outer wall of the protective plate. A plurality of expansion plates are hinged by torsion springs on the opposite sides of the plurality of limiting plates. A roller is rotatably installed inside the U-shaped groove of the expansion plate.

[0007] According to the above technical solution, a rectangular groove is opened inside the bottom of the bottom plate. Moving mechanisms are arranged at the corners of the bottom of the bottom plate. The moving mechanisms are used for the convenient movement of the whole device and the adjustment of the orientation. The driving mechanism provides a power source for the positioning drilling of the device. A control mechanism is arranged between the right sides of the bottom plate and the top plate. A push handle is arranged inside the control mechanism. The push handle is used for the staff to push the device to move.

[0008] The top of the electric telescopic rod is in contact with the bottom of the pressure plate, and two ventilation slots are symmetrically provided on the top of the protective plate. The protective plate is vertically reset by the elastic force of a spring, and the outer wall of the screw screw movably passes through the inside of the bottom plate. The expansion plate is used to increase the contact area between the protective plate and the ground. The bottom of the expansion plate is provided with a U-shaped groove. The roller converts the sliding friction between the expansion plate and the ground into rolling friction. The staff holds the push handle to push the control mechanism. After the control mechanism is subjected to force, the force is generated for the bottom plate and the top plate to generate movement. The top plate and the bottom plate cause the support rod to be subjected to force synchronously, and the moving mechanism generates a force for movement. The moving mechanism contacts the ground and generates friction and rotates, so that the equipment can achieve rolling horizontal movement. When it moves to the positioning position, the electric telescopic rod is driven to rotate by the output end of the driving mechanism. After the electric telescopic rod is started, its own telescopic end rotates and moves toward the ground. The telescopic end of the electric telescopic rod drives the drill bit to rotate and penetrate into the ground for drilling positioning. The device uses a single drive mechanism to complete positioning to optimize energy consumption. Simultaneously, the retractable end of the electric telescopic rod drives the pressure plate in orbital rotation and downward movement. This rotation of the pressure plate pushes against the protective plate, causing it to slide downward along the inside of the base plate. After the bottom of the protective plate contacts the ground, it continues to move downward, pushing against the base plate to generate an upward force. At this point, the overall upward movement of the device causes the moving mechanism to lift off the ground. Simultaneously, the protective plate drives the fixed plate downward, which in turn drives the screws in synchronous motion. Self-locking threads on the outer wall of the screws within the base plate limit the screws, causing the screws to rotate along the bottom of the fixed plate and penetrate deep into the ground, securing the protective plate to the ground. The protective plate drives the limit plate downward, which in turn drives the expansion plate in synchronous motion. When the expansion plate drives the roller downward and contacts the ground, the roller causes the hinged shaft between the expansion plate and the limit plate to begin rotating. The expansion plate then drives the roller in an arc-shaped trajectory along the ground away from the protective plate. Friction against the ground during movement causes the roller to rotate within the expansion plate until the bottom of the expansion plate contacts the ground, effectively increasing the contact area between the protective plate and the ground.

[0009] According to the above technical solution, the anti-load device includes an activated carbon plate, which passes through the inside of the activated carbon plate and is movably installed on the outer wall of the reciprocating spiral groove of the electric telescopic rod. A U-shaped frame is fixedly installed at the bottom edge of the activated carbon plate, and a cross bar is fixedly installed inside the ventilation groove of the protective plate. A baffle is passed through the outer wall of the cross bar by a torsion spring and is rotatably installed.

[0010] According to the above technical solution, the right side of the activated carbon plate is slidably installed on the outer wall of the control mechanism, and the baffle is flipped and reset after movement through a torsion spring. The top edge of the baffle is in contact with the bottom of the U-shaped frame. When the fixed end of the electric telescopic rod rotates, the non-self-locking reciprocating spiral groove opened on its own outer wall drives the activated carbon plate to slide back and forth and reset along the outer wall of the control mechanism. The activated carbon plate drives the U-shaped frame to move synchronously, and the bottom of the U-shaped frame presses the edge of the baffle. At this time, the baffle will generate a rotational force along the outer wall of the cross bar. At this time, the baffle opens the cover to the ventilation slot on the top of the protective plate. When the U-shaped frame is reset, the baffle is reset by the torsion spring, and so on.

[0011] When the shield plate is flipped to the point where it no longer conflicts with the U-shaped plate to generate the force for vertical movement, the U-shaped frame contacts the top of the U-shaped plate and presses the U-shaped plate to continue moving downward, driving the I-shaped plate to drive the I-shaped roller to move downward along the inner wall of the shield plate, and the two ends of the I-shaped roller begin to rotate inside the U-shaped plate through friction, and the I-shaped roller drives the spoiler to revolve, and the spoiler effectively accelerates the activity of the gas inside the shield plate when it revolves inside the shield plate.

[0012] According to the above technical solution, the marking device includes a marking box, the outer wall of the marking box is fixedly installed on the inner wall of the protective plate, the U-shaped plate is fixedly installed with a resistance plate close to the side of the marking box, two arc panels are symmetrically and slidably installed inside the marking box through springs, and a sliding plate is penetrated and slidably installed inside the powder outlet of the marking box.

[0013] According to the above technical solution, marking powder is provided inside the marking box, and two powder outlets are symmetrically provided at the bottom of the marking box, the arc surface of the arc panel is located on the movement trajectory of the resistance plate, and the sliding plate is used to prevent the marking powder from spilling during the non-working stage of the equipment, and the bottom of the arc panel is fixedly connected to the top corner of the sliding plate, and the U-shaped plate drives the resistance plate to move reciprocatingly downward and reset, and at the same time the protective plate limits the marking box, so when the resistance plate moves downward, it will resist the arc surface outer wall of the arc panel, and the arc panel will generate a horizontal movement force due to the resistance of the resistance plate, that is, the arc panel will slide toward the inside of the marking box, and the arc panel will then be reset by the spring force, and at the same time the arc panel drives the sliding plate to move synchronously, and the sliding plate opens the shielding of the bottom of the marking box, and when the arc panel is reset, it pulls the sliding plate to reset, and repeats the cycle.

[0014] The L-shaped plate is fixedly installed at one end of the arc panel away from the interference plate, and the L-shaped plate is slidably installed on the inner wall of the marking box on one side of the arc panel, and the outer wall of the L-shaped plate is equidistant and fixedly installed with several U-shaped blocks, and several of the U-shaped blocks are staggered with the opposite side, and round rods are rotatably installed inside the several U-shaped blocks, and gears are fixedly installed on the outer walls of the middle ends of several of the round rods, and several of the gears are meshed with the opposite side. Spiral pieces are fixedly installed on the outer walls of both ends of the round rod. When the arc panel pushes the L-shaped plate toward the center direction of the interior of the marking box, the L-shaped plate drives the U-shaped block to move synchronously, and the U-shaped block drives the round rod to move synchronously. When the symmetrically distributed U-shaped blocks and the round rods move synchronously and symmetrically, the round rods drive the gears to move synchronously, and the symmetrically distributed gears mesh with each other during movement to generate an orbital force. At this time, the gear drives the round rod to rotate along the inside of the U-shaped block, and the round rod drives the spiral piece to perform a circular motion. Thus, the spiral piece realizes horizontal movement and performs orbital motion to stir the marking powder inside the marking box.

[0015] The present invention provides an energy-saving mine foundation engineering positioning device. It has the following beneficial effects: (1) The present invention cooperates with an electric telescopic rod, a drill bit, a pressure plate, a protective plate, a screw nail, a limit plate, an expansion plate and a roller. Through the cooperation of the electric telescopic rod and the protective plate, the drill bit can quickly penetrate into the ground to complete the mine positioning work. At the same time, the protective plate and the screw nail firmly shield the positioning area, effectively preventing the drill bit from causing the centrifugal force of high-speed rotation to cause the gravel to splash around, and improving the stability of the equipment operation; the friction between the expansion plate and the ground is reduced by the self-rotation of the roller, that is, the wear of the expansion plate is effectively reduced. At the same time, the expansion plate increases the support stability between the protective plate and the ground, avoiding the vibration generated during the operation of the equipment and the uneven ground causing the equipment to shake when drilling.

[0016] (2) The present invention sets an anti-load device, cooperates with an electric telescopic rod, an activated carbon plate, a U-shaped frame, a cross bar, a shield plate, a U-shaped plate, an I-shaped roller and a spoiler, and presses the shield plate through the U-shaped frame, so that the shield plate can indirectly open the shielding inside the protective plate, so that the heat generated by the equipment during operation can be quickly discharged, thereby preventing the equipment from being damaged by overheating due to long-term and high-frequency operation, and at the same time avoiding the probability of continuous opening increasing the probability of gravel splashing out through the ventilation slot; the spoiler is driven to rotate by the I-shaped roller, effectively accelerating the exchange rate between the internal heat and the external air after the ventilation slot on the top of the protective plate is opened, thereby avoiding the long-term accumulation of heat inside the protective plate, which causes the drill bit to overheat, resulting in an increased probability of damage when the drill bit contacts the rock layer.

[0017] (3) The present invention sets a marking device, and cooperates with a U-shaped plate, a marking box, a resistance plate, an arc plate, a sliding plate, an L-shaped plate, a U-shaped block, a round rod, a gear and a spiral plate. The arc plate causes the sliding plate to move back and forth, so that the marking powder inside the marking box can indirectly fall to the ground during positioning, saving materials while achieving marking of the positioning area, which is convenient for the staff to quickly determine the positioned area during the large-scale positioning work of the mine; the horizontal and orbital motion of the spiral plate expands the stirring range of the marking powder inside the marking box, and avoids the phenomenon of marking powder agglomeration caused by the changeable temperature of the mine, and the symmetrically arranged spiral plates effectively optimize the dispersion effect of the agglomerated part of the marking powder, and avoids the marking powder falling in blocks to reduce the marking range on the ground and reduce the visibility of the staff.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] A return groove is opened inside the bottom of the bottom plate 1, moving mechanisms 2 are arranged at the bottom corners of the bottom plate 1, the moving mechanisms 2 are used for the convenient movement of the whole device and the adjustment of the orientation, the driving mechanism provides a power source for the positioning drilling of the device, a control mechanism 5 is arranged between the right sides of the bottom plate 1 and the top plate 4, and a push handle is arranged inside the control mechanism 5, and the push handle is used for the staff to push the device to move.

[0023] A non-self-locking reciprocating spiral groove is opened on the outer wall of the fixed end of the electric telescopic rod 6, the drill bit 7 is located below the bottom plate 1, and the drill bit 7 is used for opening holes and positioning on the ground. The top of the protective plate 9 is in contact with the bottom of the pressing plate 8, and two ventilation grooves are symmetrically opened at the top of the protective plate 9. The protective plate 9 realizes vertical reset through the spring force. The outer wall of the threaded nail 10 movably penetrates through the inside of the bottom plate 1. The expansion plate 12 is used to increase the contact area between the protective plate 9 and the ground. A U-shaped groove is opened at the bottom of the expansion plate 12, and the rotating roller 13 converts the sliding friction between the expansion plate 12 and the ground into rolling friction.

[0024] Through the cooperation of the electric telescopic rod 6 and the protective plate 9, the drill bit 7 can quickly penetrate into the ground to complete the mine positioning work. At the same time, the protective plate 9 and the threaded nail 10 firmly block the positioning area, effectively avoiding the phenomenon that the crushed stones fly around due to the centrifugal force of the high-speed rotation of the drill bit 7, and improving the stability of the equipment operation; by the self-rotation of the rotating roller 13, the friction between the expansion plate 12 and the ground is reduced, that is, the wear of the expansion plate 12 is effectively reduced. At the same time, the expansion plate 12 increases the support stability between the protective plate 9 and the ground, and avoids the shaking of the equipment during drilling caused by the vibration generated during the operation of the equipment and the uneven ground.

[0025] When in use, the staff holds the push handle and pushes the control mechanism 5. After the control mechanism 5 is subjected to force, the bottom plate 1 and the top plate 4 are forced to generate a force for movement. The top plate 4 and the bottom plate 1 cause the support rod 3 to be subjected to force synchronously, and the moving mechanism 2 generates a force for movement. The moving mechanism 2 contacts the ground and generates friction and rotates, so that the equipment can achieve rolling horizontal movement. When it moves to the positioning position, the electric telescopic rod 6 is driven to rotate by the output end of the driving mechanism, and after the electric telescopic rod 6 is started, its own telescopic end rotates and moves toward the ground. The telescopic end of the electric telescopic rod 6 drives the drill bit 7 to rotate and penetrate into the ground for drilling positioning. The equipment completes the positioning work through a single driving mechanism to optimize energy loss. At the same time, the telescopic end of the electric telescopic rod 6 drives the pressure plate 8 to revolve and move downward. The pressure plate 8 revolves and contacts the protective plate 9 and slides downward along the inside of the bottom plate 1. After the bottom of the protective plate 9 contacts the ground, it continues to move downward. The protective plate 9 pushes the bottom plate 1 to generate an upward force. At this time The overall upward movement of the equipment causes the mobile mechanism 2 to leave the ground. At the same time, the protective plate 9 drives the fixed plate to move downward, and the fixed plate drives the threaded nail 10 to move synchronously. Through the self-locking thread on the outer wall of the threaded nail 10 inside the bottom plate 1, the threaded nail 10 rotates along the bottom of the fixed plate and penetrates into the ground, completing the confinement between the protective plate 9 and the ground; the protective plate 9 drives the limiting plate 11 to move downward, and the limiting plate 11 drives the expansion plate 12 to move synchronously. When the expansion plate 12 drives the roller 13 to move downward and contacts the ground, the roller 13 causes the hinge shaft between the expansion plate 12 and the limiting plate 11 to start rotating. At this time, the expansion plate 12 drives the roller 13 to move in an arc trajectory along the ground away from the protective plate 9. When the roller 13 moves, the friction with the ground causes itself to rotate inside the expansion plate 12 until the bottom of the expansion plate 12 contacts the ground. At this time, the expansion plate 12 effectively expands the contact area between the protective plate 9 and the ground.

[0026] According to the above embodiment, through the cooperation of the electric telescopic rod 6 and the protective plate 9, the drill bit 7 can quickly penetrate into the ground to complete the mine positioning work. At the same time, the protective plate 9 and the threaded nails 10 firmly block the positioning area, effectively preventing the drill bit 7 from causing gravel to splash around due to the centrifugal force of high-speed rotation, and improving the stability of the equipment operation; the friction between the expansion plate 12 and the ground is reduced by the self-rotation of the roller 13, that is, the wear of the expansion plate 12 is effectively reduced. At the same time, the expansion plate 12 increases the support stability between the protective plate 9 and the ground, avoiding the vibration generated during the operation of the equipment and the uneven ground causing the equipment to shake when drilling.

[0027] See also Figures 1 - 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-load device 14; The anti-load device 14 includes an activated carbon plate 141. The activated carbon plate 141 is internally penetrated and movably installed on the outer wall of the reciprocating spiral groove of the electric telescopic rod 6. A U-shaped frame 142 is fixedly installed at the bottom edge of the activated carbon plate 141. A cross bar 143 is fixedly installed inside the ventilation groove of the protection plate 9. A baffle plate 144 is penetrated and rotatably installed on the outer wall of the cross bar 143 through a torsion spring.

[0028] The right side of the activated carbon plate 141 is slidably installed on the outer wall of the control mechanism 5. The baffle plate 144 is flipped and reset after movement through the torsion spring. The top edge of the baffle plate 144 contacts the bottom of the U-shaped frame 142.

[0029] Two U-shaped plates 145 are symmetrically and slidably installed inside the protection plate 9. The tops of the U-shaped plates 145 are located on the movement track of the baffle plate 144. An I-shaped roller 146 is rotatably installed inside the U-shaped plates 145. The I-shaped roller 146 is designed with thick ends and a thin middle. The outer walls of both ends of the I-shaped roller 146 contact the inner wall of the protection plate 9. A number of spoiler plates 147 are equidistantly and fixedly installed on the outer wall of the middle end of the I-shaped roller 146. The spoiler plates 147 are used to accelerate the gas flow rate inside the protection plate 9.

[0030] By pressing the baffle plate 144 through the U-shaped frame 142, the baffle plate 144 can be indirectly opened to block the inside of the protection plate 9, so that the heat generated during the operation of the equipment can be quickly discharged, preventing the equipment from being damaged by overheating during long-term and high-frequency operation. At the same time, it avoids continuously opening and increasing the probability of gravel splashing out through the ventilation groove; by driving the spoiler plates 147 to revolve through the I-shaped roller 146, the heat exchange rate between the heat inside the protection plate 9 and the external air can be effectively accelerated after the ventilation groove at the top of the protection plate 9 is opened, avoiding the heat inside the protection plate 9 being accumulated for a long time and causing the drill bit 7 to overheat, resulting in an increased probability of damage when the drill bit 7 contacts the rock layer.

[0031] During use, when the fixed end of the electric telescopic rod 6 rotates, through the non-self-locking reciprocating spiral groove opened on its outer wall, it drives the activated carbon plate 141 to slide downward and reset reciprocally along the outer wall of the control mechanism 5. The activated carbon plate 141 drives the U-shaped frame 142 to move synchronously. The bottom of the U-shaped frame 142 presses the edge of the shielding plate 144. At this time, a rotational force will be generated on the outer wall of the cross bar 143 by the shielding plate 144. At this time, the shielding plate 144 opens to block the ventilation slots at the top of the protection plate 9. When the U-shaped frame 142 resets, the shielding plate 144 resets through the torsion spring, and so on reciprocally; when the shielding plate 144 flips, it touches the top of the U-shaped plate 145. At this time, a downward movement force is generated on the U-shaped plate 145. When the shielding plate 144 flips to no longer touch the U-shaped plate 145 to generate a vertical movement force, the U-shaped frame 142 contacts the top of the U-shaped plate 145 and presses the U-shaped plate 145 to continue moving downward. The U-shaped plate 145 drives the I-shaped roller 146 to move downward by friction along the inner wall of the protection plate 9. Both ends of the I-shaped roller 146 start to rotate self in the U-shaped plate 145 by friction. The I-shaped roller 146 drives the spoiler 147 to revolve. When the spoiler 147 revolves inside the protection plate 9, it effectively accelerates the activity degree of the gas inside it.

[0032] According to the above embodiments, by pressing the shielding plate 144 with the U-shaped frame 142, it is promoted that the shielding plate 144 can indirectly open the shielding inside the protection plate 9, so that the heat generated during the operation of the equipment can be quickly discharged, preventing the equipment from being damaged by overheating during long-term and high-frequency operation, and at the same time avoiding the continuous opening to increase the probability of gravel splashing out through the ventilation slots; by driving the spoiler 147 to revolve with the I-shaped roller 146, it effectively accelerates the heat exchange rate between the heat inside the protection plate 9 and the external air after the ventilation slots at the top of the protection plate 9 are opened, avoiding the long-term accumulation of heat inside the protection plate 9 resulting in overheating of the drill bit 7 and increasing the probability of damage when the drill bit 7 contacts the rock layer.

[0033] Please refer to Figures 1 - 8 , on the basis of the above embodiments, another embodiment of the present invention further includes a marking device 15; The marking device 15 includes a marking box 151. The outer wall of the marking box 151 is fixedly installed on the inner wall of the protection plate 9. A contact plate 152 is fixedly installed on one side of the U-shaped plate 145 close to the marking box 151. Two arc-shaped plates 153 are symmetrically and slidably installed inside the marking box 151 through springs. A sliding plate 154 is slidably installed through the powder outlet of the marking box 151.

[0034] The marking powder is arranged inside the marking box 151. Two powder outlets are symmetrically opened at the bottom of the marking box 151. The arc surface of the arc-shaped plate 153 is located on the movement track of the contact plate 152. The sliding plate 154 is used to block the marking powder from spilling during the non-working stage of the equipment. The bottom of the arc-shaped plate 153 is fixedly connected to the top corner of the sliding plate 154.

[0035] An L-shaped plate 155 is fixedly installed on one end of the arc panel 153 away from the resistance plate 152, and the L-shaped plate 155 is slidably installed on the inner wall of the marking box 151 close to the arc panel 153. A number of U-shaped blocks 156 are equidistantly and fixedly installed on the outer wall of the L-shaped plate 155. The U-shaped blocks 156 are staggered with the opposite side, and round rods 157 are rotatably installed inside the U-shaped blocks 156. Gears 158 are fixedly installed on the outer walls of the middle ends of the round rods 157. The gears 158 are meshed with the opposite side, and spiral pieces 159 are fixedly installed on the outer walls of both ends of the round rods 157.

[0036] The arc panel 153 causes the sliding plate 154 to perform reciprocating motion, causing the marking powder inside the marking box 151 to indirectly fall to the ground during positioning, saving materials while achieving marking of the positioning area, facilitating the large-scale positioning work in the mine, so that the staff can quickly determine the located area; the horizontal and orbital motion of the spiral blade 159 expands the stirring range of the marking powder inside the marking box 151, avoiding the agglomeration of the marking powder due to the changeable temperature in the mine, and the symmetrically arranged spiral blades 159 effectively optimize the dispersion effect of the agglomerated part of the marking powder, avoiding the marking powder falling in blocks to reduce the marking range on the ground and reduce the visibility of the staff.

[0037] When in use, the U-shaped plate 145 drives the contact plate 152 to move back and forth downward and reset, and at the same time the protective plate 9 limits the mark box 151, so when the contact plate 152 moves downward, it will interfere with the curved outer wall of the arc panel 153, and the arc panel 153 will generate a horizontal movement force due to the interference of the contact plate 152, that is, the arc panel 153 will slide toward the inside of the mark box 151, and the arc panel 153 will then reset by the spring force. At the same time, the arc panel 153 drives the sliding plate 154 to move synchronously, and the sliding plate 154 opens the cover on the bottom of the mark box 151. When the arc panel 153 is reset, it pulls the sliding plate 154 to reset, and the cycle repeats. When the L-shaped plate 155 is pushed to move toward the center of the marking box 151, the L-shaped plate 155 drives the U-shaped block 156 to move synchronously, and the U-shaped block 156 drives the round rod 157 to move synchronously. When the symmetrically distributed U-shaped block 156 and the round rod 157 move synchronously and symmetrically, the round rod 157 drives the gear 158 to move synchronously. When the symmetrically distributed gears 158 move, they engage with each other to generate a revolution force. At this time, the gear 158 drives the round rod 157 to rotate along the inside of the U-shaped block 156, and the round rod 157 drives the spiral piece 159 to perform a circular motion. As a result, the spiral piece 159 realizes horizontal movement and performs revolution to stir the marking powder inside the marking box 151.

[0038] According to the above embodiments, the arc-shaped panel 153 is used to promote the reciprocating movement of the sliding plate 154, so that the marking powder inside the marking box 151 can fall to the ground indirectly during positioning, saving materials while realizing the marking of the positioning area, facilitating the rapid determination of the positioned area by the staff during the large-scale positioning work in the mine; through the horizontal and revolving movement of the spiral blade 159, the agitation range of the marking powder inside the marking box 151 is expanded, avoiding the caking phenomenon of the marking powder caused by the changeable temperature in the mine, and the symmetrically arranged spiral blades 159 effectively optimize the dispersion effect of the caked part of the marking powder, preventing the marking powder from falling in lumps to reduce the marking range on the ground and reducing the visibility of the staff.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
