Description

Technical Field

[0001] This utility model relates to the field of geological and mineral exploration technology, specifically a safety protection device for geological and mineral exploration drilling. Background Technology

[0002] Geological exploration, broadly speaking, can be understood as geological work. It is the investigation and research work conducted on the geological conditions of rocks, stratigraphy, minerals, groundwater, landforms, etc. in a certain area, based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying, geophysical exploration, geochemical prospecting, drilling, pit exploration, sampling and testing, and geological remote sensing.

[0003] Chinese patent provides a safety protection device for geological and mineral exploration drilling, publication number CN216110567U. The device includes a main body, a support platform, handles on both sides of the support platform, and anti-slip sleeves on the outer side of each handle. Support legs are located on both sides of the bottom of the support platform, with a groove on each corresponding side of each support leg. A fixing structure is located on the bottom of each support leg away from the groove, facilitating user fixation. A movable plate is located at the bottom of the support platform between the support legs, with a second motor at the bottom of the movable plate and a drill barrel at the bottom of the second motor. Inside the support legs are movable structures that allow the user to move the drill bit up and down. These movable structures allow for geological exploration without manual pressing, saving effort and improving work efficiency.

[0004] However, during drilling, the high-speed rotation of the drill bit can easily bring out rock fragments and cause splashes, which can easily cause injury to the surrounding workers. Therefore, a safety protection device for geological and mineral exploration drilling is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a safety protection device for geological and mineral exploration drilling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for geological and mineral exploration drilling, comprising a base, a support frame, and a drill bit. The support frame is equipped with a protective mechanism and a cleaning mechanism. The protective mechanism includes a fixed plate fixedly mounted on the support frame, a roller rotatably mounted on the fixed plate, a protective cloth wound around the roller, and a winding motor connected to the roller mounted on one side of the fixed plate. A counterweight plate is fixedly connected to the free end of the protective cloth, a positioning hole is provided on the counterweight plate, and a first screw hole and a second screw hole are provided on the support frame. A bolt adapted to the first screw hole and the second screw hole is inserted into the positioning hole.

[0007] Preferably, a partition is fixedly installed on the support frame, a cylinder is installed on the partition, the output rod of the cylinder slides through the partition and is fixedly connected to a lifting plate, a limit rod is fixedly installed between the base and the partition, and the lifting plate is slidably connected to the limit rod.

[0008] Preferably, the drill bit is rotatably mounted at the bottom of the lifting plate, a driven gear is fixedly sleeved on the drill bit, a drilling motor is mounted on the lifting plate, and the output shaft of the drilling motor rotatably passes through the lifting plate and is fixedly connected to a driving gear that meshes with the driven gear.

[0009] Preferably, the cleaning mechanism includes a water tank fixedly mounted on a support frame, a water injection pipe connected to the water tank, a fixed base fixedly mounted on the support frame, and a cylinder fixedly mounted on the fixed base.

[0010] Preferably, a piston is slidably disposed inside the cylinder, a push-pull rod is fixedly disposed at the bottom of the piston, connecting blocks are fixedly disposed at both ends of the lifting plate, a sliding groove is provided on the support frame to slidably connect with the connecting blocks, and the push-pull rod slidably passes through the cylinder and is fixedly connected to the connecting blocks.

[0011] Preferably, an inlet pipe is connected between the cylinder and the water tank, and an outlet pipe is connected to the cylinder. Both the inlet and outlet pipes are equipped with one-way valves, and the two one-way valves are installed in opposite directions.

[0012] Preferably, a support ring is fixedly installed on the base, a water collection ring is fixedly installed on the support ring, the water outlet pipe passes through the support frame and communicates with the water collection ring, and multiple nozzles are connected to the water collection ring.

[0013] Preferably, the base is screwed with screws for fixing the base, and the base has drilling holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This safety protection device for geological and mineral exploration drilling uses a winding motor to rotate the roller. When the roller rotates, the protective cloth extends downward under the weight of the counterweight plate until the counterweight plate moves onto the base. At this point, the two protective cloths completely cover both sides of the support frame. Then, screws are inserted into the positioning holes and screwed into the second screw holes to lock the counterweight plate in this position. The two protective cloths and the support frame can provide closed protection around the drill bit, so that the debris brought out by the drilling can be blocked by the protective cloths and the support frame, thereby preventing debris from splashing and causing injury to the workers.

[0016] 2) The safety protection device used for geological and mineral exploration drilling involves a lifting plate that moves the drill bit downwards. When the drill bit moves downwards, the connecting block slides along the groove and moves the push-pull rod downwards. The push-pull rod moves the piston downwards, creating a pressure difference inside the cylinder. This allows water from the water tank to be drawn into the cylinder through the inlet pipe. When the drill bit moves upwards after drilling, the connecting block moves the push-pull rod upwards, causing the piston to move upwards inside the cylinder. At this time, water inside the cylinder can be squeezed into the water collection ring through the outlet pipe and sprayed out through the nozzle. The two one-way valves prevent backflow of water inside the cylinder. The water sprayed from the nozzle can wash the surface of the drill bit, washing away the soil adhering to the drill bit and preventing it from affecting subsequent drilling operations.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Combination Figures 1-5 A safety protection device for geological and mineral exploration drilling includes a base 1, a support frame 2, and a drill bit 3. A partition 5 is fixedly installed on the support frame 2, and a cylinder 6 is installed on the partition 5. The output rod of the cylinder 6 slides through the partition 5 and is fixedly connected to a lifting plate 7. A limit rod 13 is fixedly installed between the base 1 and the partition 5. The lifting plate 7 is slidably connected to the limit rod 13. The drill bit 3 is rotatably installed at the bottom of the lifting plate 7. A driven gear 8 is fixedly sleeved on the drill bit 3. A drilling motor 9 is installed on the lifting plate 7. The output shaft of the drilling motor 9 rotatably passes through the lifting plate 7 and is fixedly connected to a driving gear 10 that meshes with the driven gear 8. A screw 11 for fixing the base 1 is screwed onto the base 1. A drilling hole 14 is opened on the base 1. A protective mechanism 4 and a cleaning mechanism 12 are provided on the support frame 2.

[0029] See Figure 2 and Figure 3 Furthermore, the protective mechanism 4 includes a fixed plate 41 fixedly mounted on the support frame 2, a roller 42 rotatably mounted on the fixed plate 41, a protective cloth 43 wound around the roller 42, and a winding motor 44 connected to the roller 42 mounted on one side of the fixed plate 41; a counterweight plate 45 is fixedly connected to the free end of the protective cloth 43, a positioning hole 46 is provided on the counterweight plate 45, a first screw hole 48 and a second screw hole 49 are provided on the support frame 2, and a bolt 47 adapted to the first screw hole 48 and the second screw hole 49 is inserted into the positioning hole 46.

[0030] Specifically, by starting the winding motor 44, the winding roller 42 is rotated. When the winding roller 42 rotates, the protective cloth 43 extends downward under the gravity of the counterweight plate 45 until the counterweight plate 45 moves onto the base 1. At this time, the two protective cloths 43 completely cover both sides of the support frame 2. Then, the screw 11 is inserted into the positioning hole 46 and screwed into the second screw hole 49, so that the counterweight plate 45 is locked in this position. The two protective cloths 43 and the support frame 2 can provide closed protection around the drill bit 3, so that the gravel brought out by the drilling can be blocked by the protective cloths 43 and the support frame 2, thereby preventing the gravel from splashing and causing injury to the workers.

[0031] See Figure 4 and Figure 5Furthermore, the cleaning mechanism 12 includes a water tank 121 fixedly mounted on a support frame 2, a water injection pipe 122 connected to the water tank 121, a fixed base 123 fixedly mounted on the support frame 2, a cylinder 124 fixedly mounted on the fixed base 123, a piston 125 slidably mounted inside the cylinder 124, a push-pull rod 126 fixedly mounted at the bottom of the piston 125, connecting blocks 127 fixedly mounted at both ends of the lifting plate 7, a sliding groove 128 slidably connected to the connecting block 127 on the support frame 2, and the push-pull rod 126 slidably passes through the cylinder 124 and... A water inlet pipe 129 is fixedly connected to the connecting block 127 and is provided between the cylinder 124 and the water tank 121. A water outlet pipe 1210 is provided on the cylinder 124. A one-way valve 1214 is installed on both the water inlet pipe 129 and the water outlet pipe 1210. The two one-way valves 1214 are installed in opposite directions. A support ring 1211 is fixedly provided on the base 1. A water collection ring 1212 is fixedly provided on the support ring 1211. The water outlet pipe 1210 passes through the support frame 2 and is connected to the water collection ring 1212. Multiple nozzles 1213 are provided on the water collection ring 1212.

[0032] Specifically, when the drill probe 3 is moved downward by the lifting plate 7, the connecting block 127 slides along the slide groove 128 and moves the push-pull rod 126 downward. The push-pull rod 126 moves the piston 125 downward, creating a pressure difference in the cylinder 124. This allows water in the water tank 121 to be drawn into the cylinder 124 through the inlet pipe 129. When the drill probe 3 moves upward after drilling, the connecting block 127 moves the push-pull rod 126 upward, causing the piston 125 to move upward within the cylinder 124. At this time, water in the cylinder 124 can be squeezed into the water collection ring 1212 through the outlet pipe 1210 and sprayed out through the nozzle 1213. The two one-way valves 1214 prevent water backflow in the cylinder 124. The water sprayed from the nozzle 1213 can wash the surface of the drill probe 3, allowing the soil adhering to the surface of the drill probe 3 to be washed off, thus avoiding affecting subsequent drilling operations.

[0033] In actual operation, the device is fixed at the drilling position by screw 11. The drilling motor 9 is started to drive the driven gear 8 to rotate by the drive gear 10, so that the drill bit 3 starts to work. Then, the cylinder 6 is started to drive the lifting plate 7 to move the drill bit 3 downward under the guidance of the limit rod 13. The drill bit 3 passes through the drilling hole 14 and drills into the ground to start drilling operations.

[0034] During drilling, the screw 11 is removed from the first screw hole 48. Then, the winding motor 44 is started to rotate the winding roller 42. When the winding roller 42 rotates, the protective cloth 43 extends downward under the gravity of the counterweight plate 45 until the counterweight plate 45 moves onto the base 1. At this time, the two protective cloths 43 completely cover both sides of the support frame 2. Then, the screw 11 is inserted into the positioning hole 46 and screwed into the second screw hole 49, so that the counterweight plate 45 is locked in this position. The two protective cloths 43 and the support frame 2 can provide closed protection around the drill bit 3, so that the debris brought out by the drilling can be blocked by the protective cloth 43 and the support frame 2, thereby preventing the debris from splashing and causing injury to the workers.

[0035] When the lifting plate 7 moves the drill bit 3 downward, the connecting block 127 slides along the slide groove 128 and moves the push-pull rod 126 downward. The push-pull rod 126 moves the piston 125 downward, creating a pressure difference in the cylinder 124. This allows water in the water tank 121 to be drawn into the cylinder 124 through the inlet pipe 129. When the drill bit 3 moves upward after drilling, the connecting block 127 moves the push-pull rod 126 upward, causing the piston 125 to move upward within the cylinder 124. At this time, water in the cylinder 124 can be squeezed into the water collection ring 1212 through the outlet pipe 1210 and sprayed out through the nozzle 1213. The two one-way valves 1214 prevent water backflow in the cylinder 124. The water sprayed from the nozzle 1213 can wash the surface of the drill bit 3, allowing the soil adhering to the surface of the drill bit 3 to be washed off, thus avoiding affecting subsequent drilling operations.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
