Description

Technical Field

[0001] This invention belongs to the field of geological exploration technology, specifically a trenching excavation and rock extraction device and method. Background Technology

[0002] Trenching is a core method in geological and mineral exploration used to expose bedrock, observe geological phenomena, and collect rock and mineral samples. It is widely used in scenarios such as vein tracing, stratigraphic profile research, and ore grade analysis. Traditional trenching rock extraction operations mostly rely on manual labor or simple mechanical assistance, which is cumbersome, labor-intensive, and difficult to guarantee the quality of sampling. Existing dedicated rock extraction equipment still has significant technical defects.

[0003] Existing trench rock extraction devices typically use a single set of cutting tools to cut the rock wall in a plane, which can only form rectangular or square trenches and cannot directly separate complete long strip rock samples. During operation, it is necessary to first cut parallel grooves on the rock wall with the cutting tool. After the cutting is completed, the rock sample still has a lot of connection with the parent rock. It is necessary for the staff to repeatedly knock and pry with tools such as crowbars and hammers to peel the rock sample off the rock wall. Because the rock sample after cutting is still connected to the parent rock, peeling the rock sample requires a dedicated person to knock and pry at a high frequency, resulting in low work efficiency.

[0004] Therefore, the present invention provides a trenching excavation rock extraction device and a rock extraction method. Summary of the Invention

The output shaft of each rotating cylinder is fixedly connected to the cross-cutting blade, and a transverse moving component is provided on the inner wall of the receiving box.

[0009] Preferably, the lateral movement component includes an automatic telescopic rod B, two of which are symmetrically fixedly installed on the inner wall of the receiving box, a connecting seat is fixedly installed between the output shafts of the two automatic telescopic rods B, and a spacing adjustment component is provided between the connecting seat and the mounting plate.

[0010] Preferably, the spacing adjustment assembly includes a translation seat, which is fixedly installed on the outer wall of the connecting seat. The outer wall of the translation seat is slidably connected to the inner wall of the receiving box. Translation blocks are symmetrically slidably installed on the inner wall of the translation seat. Two mounting plates are respectively fixedly installed on the top of the translation blocks. A bidirectional screw is rotatably installed on the inner wall of the translation seat. The translation blocks are all threadedly connected to the bidirectional screw. A rotating ring is fixedly installed at one end of the bidirectional screw.

[0011] Preferably, a feeding plate is fixedly installed on the inner wall of the receiving box, a hook plate is fixedly installed on the outer wall of the feeding plate, the hook plate is located between two cross-cutting blades, and a collection box is slidably installed on the inner wall of the receiving box, the collection box being located below the feeding plate.

[0012] Preferably, the inner wall of the connecting seat is provided with an air guide groove, the top of the connecting seat is provided with a plurality of exhaust holes, the plurality of exhaust holes are all connected to the air guide groove, the inner wall of the exhaust holes is fixedly installed with a filter screen, and an air supply component is provided on one side of the connecting seat.

[0013] Preferably, the gas supply assembly includes a gas supply box, which is fixedly installed on one side of the connecting seat. A positioning horizontal plate is fixedly installed on the inner wall of the receiving box, a positioning vertical plate is fixedly installed on the outer wall of the positioning horizontal plate, and a piston plate is fixedly installed on the outer wall of the positioning vertical plate. The outer wall of the piston plate is slidably connected to the inner wall of the gas supply box.

[0014] Preferably, the traveling component includes a chassis, and the mounting base and the housing are both fixedly installed on the top of the chassis. Two sets of drive wheels are symmetrically installed on the inner wall of the chassis.

[0015] A rock sampling method using a trench excavation rock sampling device includes the following steps: S1: Place the device in the dug trench. After starting the device, the drive motor drives the two oblique cutters to rotate. The automatic telescopic rod A extends and pushes the oblique cutter into the rock wall. The drive wheel rotates and moves the device forward along the trench. The oblique cutter moves forward while rotating. The two oblique cutters cut the rock wall one after the other, cutting out triangular strips of rock on the surface of the rock wall.

[0016] S2: As the device moves forward, the cross-cutting blade will move to the triangular elongated rock sample. The rotating cylinder will drive the two cross-cutting blades to rotate. The automatic telescopic rod B will extend and push the cross-cutting blades out. The cross-cutting blades will cut into the elongated rock sample laterally and stop rotating. The elongated rock sample will be stuck between the two cross-cutting blades. At this time, the automatic telescopic rod B will retract and drive the cross-cutting blades to move backward. When the cross-cutting blades move backward, they will bring out the elongated rock sample.

[0017] S3: When the automatic telescopic rod B retracts, the connecting seat will drive the air supply box to move backward. When the air supply box moves backward, the piston plate will move relative to the air supply box, thereby compressing the air in the air supply box. After being compressed, the air will pass through the air guide groove and be ejected through the exhaust hole. The air ejected through the exhaust hole will blow towards the surface of the long rock sample, thereby blowing off the soil and gravel on the surface of the long rock sample.

[0018] S4: After the cross-cutting blade moves back to its reset position, the rotating cylinder drives the cross-cutting blade to rotate synchronously. When the cross-cutting blade rotates, it will cause the long rock sample to rotate to the inside of the hook plate. At this time, the automatic telescopic rod B extends and causes the cross-cutting blade to move outward again. The hook plate will cause the long rock sample to fall off. The fallen long rock sample will slide down along the hook plate and the feeding plate into the collection box for collection.

[0019] The beneficial effects of this invention are as follows: 1. This invention employs two sets of staggered, counter-sloping oblique cutters working together. Compared to the traditional parallel straight cutting structure, it can directly cut triangular strip rock samples into shape on the rock wall. The triangular rock sample is only connected to the parent rock of the rock wall at the end, with a small contact area and low bonding strength, which weakens the connection stress of the rock sample. There is no need for workers to repeatedly strike and pry the rock wall at close range with a hand hammer or crowbar. The rock sample can be separated with only slight force, which greatly reduces the amount of manual labor required for rock exploration in the field.

[0020] 2. This invention adds a receiving box, a rotating cylinder, and a symmetrical transverse cutting blade, which, together with the transverse moving component, can transversely cut triangular strip rock samples into segments, achieving segmented rock sample extraction. The surface of the transverse cutting blade is treated with anti-slip material. After the transverse cutting blade cuts into the rock sample and stops rotating, the rock sample can be clamped and limited by the blade body. Relying on the transverse moving component, the rock sample can be directly peeled and brought out from the rock wall by retraction. The entire process does not require manual knocking or prying to separate the rock sample, completely eliminating the manual rock wall peeling process.

[0021] 3. This invention utilizes a feeding plate and a hook plate, relying on the existing linkage of the rotating cross-cutting blade and the secondary extension and retraction of the automatic telescopic rod B, to automatically detach the rock sample from the cross-cutting blade by relying on the limiting and blocking action of the hook plate. There is no need for manual removal of the rock sample; the detached rock sample slides down autonomously by gravity for collection, realizing fully automatic unloading and automatic collection of rock samples. The entire process of cutting, picking, unloading, and collection is integrated, greatly reducing manual intervention, further improving the automation level of the entire process of trench exploration and rock extraction, and improving the efficiency of field sampling operations.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 4 As shown in the embodiment of the present invention, a trench excavation and rock-removing device includes a mounting base 1. Two mounting boxes 2 are arranged alternately on one side of the mounting base 1. A beveled cutter 3 is rotatably mounted on the inner wall of each mounting box 2, and the two beveled cutters 3 are inclined in opposite directions. A drive motor 4 is fixedly mounted on the outer wall of each mounting box 2, and the two drive motors 4 are respectively connected to the two beveled cutters 3. An insertion component is provided between each mounting box 2 and the mounting base 1, and a traveling component is provided at the bottom of the mounting base 1. During rock-removing operations, the device is placed in the excavated trench. After starting the device, the two drive motors 4 drive the two beveled cutters 3 to rotate at high speed. The insertion component extends and pushes the high-speed rotating beveled cutter 3 to cut into the rock wall at an angle. The traveling component drives the device to move along the trench. The two beveled cutters 3 are arranged alternately, and as the device moves, the two beveled cutters 3 cut the rock wall sequentially. Because the two beveled cutters 3 are inclined in opposite directions... Therefore, the two oblique cutting blades 3 will cut triangular strips of rock on the surface of the rock wall. The edge movement trajectories of the two oblique cutting blades 3 overlap, so the cut triangular strips of rock are only connected to the parent rock at the ends. The workers only need to tap the triangular strips of rock to remove the rock sample. In summary, the present invention uses two sets of oblique cutting blades 3 arranged in an alternating manner and tilted in opposite directions to work together. Compared with the traditional parallel straight cutting structure, it can directly cut triangular strips of rock on the rock wall. The triangular rock sample is only connected to the parent rock at the ends, with a small contact area and low bonding strength, which weakens the connection stress of the rock sample. It eliminates the need for workers to repeatedly strike and pry the rock wall at close range with a hammer or crowbar. Only a slight force is needed to separate the rock sample, which greatly reduces the amount of manual labor in field trench rock exploration, simplifies the rock extraction process, improves the overall efficiency of trench rock exploration, and avoids the problems of rock sample breakage and damage to the original geological structure caused by strong manual knocking, ensuring the integrity of the rock sample and meeting the geological exploration sampling standards.

[0027] like Figures 3 to 4As shown, the extension assembly includes an automatic telescopic rod A5, which is fixedly installed on the inner wall of the mounting base 1. A receiving seat 6 is fixedly installed on the outer wall of the mounting box 2. The output end of the automatic telescopic rod A5 is fixedly connected to the outer wall of the receiving seat 6. A slip ring 7 is fixedly installed on the outer wall of the receiving seat 6. A sliding rod 8 is fixedly installed on the inner wall of the mounting base 1. The outer wall of the sliding rod 8 is slidably connected to the inner wall of the slip ring 7. During rock extraction, the automatic telescopic rod A5 extends to push the receiving seat 6 to move. When the receiving seat 6 moves, it drives the bevel cutter 3 to move through the mounting box 2, thereby causing the bevel cutter 3 to extend outward at an angle and cut into the rock wall. When the rock extraction is completed, the automatic telescopic rod A5 retracts, thereby resetting the bevel cutter 3. When the receiving seat 6 moves, the slip ring 7 slides along the sliding rod 8. The sliding rod 8 and the slip ring 7 limit the receiving seat 6, preventing the bevel cutter 3 from deviating and shaking, effectively ensuring the stability of the bevel cutter 3's cutting angle and the regularity of the cutting trajectory.

[0028] like Figures 1 to 2 and Figures 5 to 8 As shown, a receiving box 9 is fixedly installed on the outer wall of the mounting base 1. Mounting plates 10 are symmetrically arranged on the inner side of the receiving box 9. A transverse cutting blade 11 is rotatably mounted on the inner wall of each mounting plate 10. A rotating cylinder 12 is fixedly installed on the outer wall of each mounting plate 10. The output shafts of the rotating cylinders 12 are fixedly connected to the transverse cutting blades 11. A transverse moving assembly is provided on the inner wall of the receiving box 9. When the device moves forward in the trench, the oblique cutting blade 3 cuts out triangular strips of rock on the rock wall. The transverse cutting blades 11 move forward with the device, so they pass by one side of the triangular strip of rock. When the transverse cutting blade 11 is on one side of the triangular strip of rock, the two rotating cylinders 12 drive the two transverse cutting blades 11 to rotate synchronously. The transverse moving assembly pushes the two transverse cutting blades 11 out from the inside of the receiving box 9. The pushed-out transverse cutting blade 11 cuts laterally into the triangular strip of rock and stops rotating, cutting out a single segment of the strip of rock. The surface of the transverse cutting blade 11 is treated with an anti-slip coating. The cut segment is long... The rock sample may get stuck between the two transverse cutting blades 11. At this time, the lateral moving component drives the two transverse cutting blades 11 to retract, and the transverse cutting blades 11 can bring out one end of the cut rock sample. The rock sample can simply be removed from between the two transverse cutting blades 11. In summary, the present invention adds a receiving box 9, a rotating cylinder 12, and symmetrical transverse cutting blades 11, etc., and in conjunction with the lateral moving component, can laterally cut triangular strip rock samples into segments, realizing the segmented cutting of rock samples. The surface of the transverse cutting blades 11 is made with an anti-slip surface. The cross-cutting blade 11 cuts into the rock sample and stops rotating, allowing the blade to hold and limit the rock sample. The cross-cutting blade then moves backward using the lateral moving component to directly peel the rock sample from the parent rock wall. The entire process eliminates the need for manual hammering or prying to separate the rock sample, completely eliminating the manual rock wall peeling process and further reducing human intervention. The cross-cutting blade 11 is precisely controlled by a cylinder, ensuring stable cutting action and a smooth cut surface, reducing rock sample breakage and further ensuring the integrity of the extracted rock sample. This makes it suitable for efficient field sampling operations.

[0029] like Figures 6 to 7 As shown, the lateral movement component includes an automatic telescopic rod B13. Two automatic telescopic rods B13 are symmetrically fixedly installed on the inner wall of the receiving box 9. A connecting seat 14 is fixedly installed between the output shafts of the two automatic telescopic rods B13. A spacing adjustment component is provided between the connecting seat 14 and the mounting plate 10. When the rock sample is cut into segments, the automatic telescopic rod B13 will extend, thereby pushing the connecting seat 14 outward. When the connecting seat 14 moves outward, it will drive the mounting plate 10 to move outward through the spacing adjustment component, thereby causing the transverse cutter 11 to extend laterally. After the transverse cutter 11 completes the cutting of the rock sample, the automatic telescopic rod B13 will retract, thereby causing the transverse cutter 11 to move backward and take the rock sample out.

[0030] like Figures 7 to 8 As shown, the spacing adjustment assembly includes a translation seat 15, which is fixedly installed on the outer wall of the connecting seat 14. The outer wall of the translation seat 15 is slidably connected to the inner wall of the receiving box 9. Translation blocks 16 are symmetrically slidably installed on the inner wall of the translation seat 15. Two mounting plates 10 are respectively fixedly installed on the top of the translation blocks 16. A bidirectional screw 17 is rotatably installed on the inner wall of the translation seat 15. The translation blocks 16 are all threadedly connected to the bidirectional screw 17. A rotating ring 18 is fixedly installed at one end of the bidirectional screw 17. Before rock scavenging, the rotating ring 18 is rotated. When rotated, the bidirectional screw 17 will rotate. The surface of the bidirectional screw 17 has two reverse threads. The two translation blocks 16 are threaded to the bidirectional screw 17 through these two threads. Therefore, when the bidirectional screw 17 rotates, it will drive the two translation blocks 16 to move synchronously in opposite directions. When the translation blocks 16 move, they will drive the cross-cutting blades 11 to move through the mounting plate 10. Adjusting the clamping distance of the two sets of cross-cutting blades 11 allows for free control of the specifications and length of the rock sample to meet the sampling and testing needs of rock samples of different sizes and specifications in geological exploration.

[0031] like Figure 6 and Figure 10As shown, a feeding plate 19 is fixedly installed on the inner wall of the receiving box 9, and a hook plate 20 is fixedly installed on the outer wall of the feeding plate 19. The hook plate 20 is located between two cross-cutting blades 11. A collection box 21 is slidably installed on the inner wall of the receiving box 9, and the collection box 21 is located below the feeding plate 19. After the cross-cutting blades 11 retract and bring out the rock sample, the cross-cutting blades 11 will first enter the inner side of the receiving box 9 for resetting. Then, the two rotating cylinders 12 drive the two cross-cutting blades 11 to rotate synchronously. When the cross-cutting blades 11 rotate, they will drive the rock sample to rotate. The rotated rock sample will enter the inner side of the hook plate 20. At this time, the automatic telescopic rod B13 extends again to push the cross-cutting blades 11 outward. When the cross-cutting blades 11 move outward, the rock sample will be pushed outward. The sample is hooked out by the hook plate 20, and the hooked rock sample slides down the inclined surface of the hook plate 20 and the feeding plate 19 into the collection box 21. In summary, the present invention uses the feeding plate 19 and the hook plate 20, relying on the original action linkage of the rotation of the cross-cutting blade 11 and the secondary extension and retraction of the automatic telescopic rod B13, and the hook plate 20 can limit and block the rock sample to automatically detach from the cross-cutting blade 11. There is no need to manually remove the rock sample. The detached rock sample slides down autonomously by gravity and is collected, realizing fully automatic unloading and automatic collection of rock samples. The whole process realizes the integrated operation of cutting, picking, unloading and collection, which greatly reduces manual intervention, further improves the automation level of the whole process of trench exploration and rock extraction, and improves the efficiency of field sampling operations.

[0032] like Figure 7 and Figure 12 As shown, the inner wall of the connecting seat 14 is provided with a gas guide groove 22, and the top of the connecting seat 14 is provided with a number of exhaust holes 23 evenly distributed. The exhaust holes 23 are all connected to the gas guide groove 22, and the inner wall of each exhaust hole 23 is fixedly installed with a filter screen. An air supply component is provided on one side of the connecting seat 14. During the process of the cross-cutting blade 11 resetting with the rock sample, the cross-cutting blade 11 will slowly rotate with the rock sample towards the exhaust hole 23. At the same time, the air supply component will supply air into the gas guide groove 22. After the gas enters the gas guide groove 22, it will be ejected through the exhaust hole 23. As the rock sample rotates, its angle changes continuously. The gas ejected from the exhaust port 23 blows towards the rock sample from different angles, thereby blowing off dust, soil, and other impurities from the surface of the rock sample. In summary, by using the cross-cutting blade 11 to drive the rock sample to rotate in conjunction with the air jet from the exhaust port 23, the floating dust, fine soil, and rock debris attached to the surface of the rock sample can be blown away from multiple angles, removing impurities from the surface of the rock sample in advance and preventing impurities from sliding down into the collection box 21 along with the intact rock sample. This effectively improves the cleanliness of the collected rock sample and eliminates the need for manual sieving and cleaning of impurities in the later stages.

[0033] like Figures 6 to 7 , Figure 9 and Figure 11As shown, the air supply assembly includes an air supply box 24, which is fixedly installed on one side of the connecting seat 14. A positioning horizontal plate 25 is fixedly installed on the inner wall of the receiving box 9, and a positioning vertical plate 26 is fixedly installed on the outer wall of the positioning horizontal plate 25. A piston plate 27 is fixedly installed on the outer wall of the positioning vertical plate 26, and the outer wall of the piston plate 27 is slidably connected to the inner wall of the air supply box 24. When the automatic telescopic rod B13 retracts and drives the cross-cutting blade 11 to reset, the connecting seat 14 will drive the air supply box 24 to move under the action of the automatic telescopic rod B13. The piston plate 27 moves through the positioning vertical plate 26. Plate 26 and positioning horizontal plate 25 are fixed. When the air supply box 24 moves, it will move relative to the piston plate 27. The piston plate 27 will squeeze the air in the air supply box 24. After being squeezed, the air will enter the air guide groove 22, thereby supplying air into the air guide groove 22. The gas entering the air guide groove 22 will be ejected through the exhaust hole 23, thereby cleaning the surface of the rock sample. The airflow is generated by the material retraction action. There is no need for separate electrical control to start and stop the air jet. It is suitable for trenching operations in the field without external power supply and with harsh working conditions, reducing the equipment operation and maintenance and usage costs.

[0034] like Figures 1 to 2 As shown, the traveling component includes a chassis 28, with the mounting base 1 and the housing 9 both fixedly installed on the top of the chassis 28. Two sets of drive wheels 29 are symmetrically installed on the inner wall of the chassis 28. By fixing the mounting base 1 and the housing 9 to the top of the chassis 28, the entire machine can be driven to move at a constant speed along the trench by rotating the drive wheels 29. It can be used with the oblique cutter 3 to continuously cut long rock samples, and is suitable for continuous sampling operations in long trenches.

[0035] A rock sampling method using a trench excavation rock sampling device includes the following steps: S1: Place the device in the dug trench. After starting the device, the drive motor 4 drives the two oblique cutters 3 to rotate. The automatic telescopic rod A5 extends and pushes the oblique cutter 3 into the rock wall. The drive wheel 29 rotates to make the device move forward along the trench. The oblique cutter 3 moves forward while rotating. The two oblique cutters 3 cut the rock wall one after another, cutting out triangular strips of rock on the surface of the rock wall.

[0036] S2: As the device moves forward, the cross-cutting blade 11 will move to the triangular elongated rock sample. The rotating cylinder 12 will drive the two cross-cutting blades 11 to rotate. The automatic telescopic rod B13 will extend and push the cross-cutting blade 11 out. The cross-cutting blade 11 will cut into the elongated rock sample laterally and stop rotating. The elongated rock sample will be stuck between the two cross-cutting blades 11. At this time, the automatic telescopic rod B13 will retract and drive the cross-cutting blade 11 to move backward. When the cross-cutting blade 11 moves backward, it will bring out the elongated rock sample.

[0037] S3: When the automatic telescopic rod B13 retracts, the connecting seat 14 will drive the air supply box 24 to move backward. When the air supply box 24 moves backward, the piston plate 27 will move relative to the air supply box 24, thereby compressing the air in the air supply box 24. After being compressed, the air will pass through the air guide groove 22 and be ejected through the exhaust hole 23. The air ejected through the exhaust hole 23 will blow towards the surface of the long rock sample, thereby blowing off the soil and gravel on the surface of the long rock sample.

[0038] S4: After the cross-cutting blade 11 moves back to its reset position, the rotating cylinder 12 drives the cross-cutting blade 11 to rotate synchronously. When the cross-cutting blade 11 rotates, it will cause the long rock sample to rotate to the inside of the hook plate 20. At this time, the automatic telescopic rod B13 extends and causes the cross-cutting blade 11 to move outward again. The hook plate 20 will cause the long rock sample to fall off. The fallen long rock sample will slide down along the hook plate 20 and the feed plate 19 into the collection box 21 for collection.

10. A rock extraction method using a trenching excavation rock extraction device, characterized in that: The rock extraction method of this trenching rock extraction device uses the trenching rock extraction device as described in claims 1-9, and the specific rock extraction method includes the following steps: S1: Place the device in the dug trench. After starting the device, the drive motor (4) drives the two oblique cutters (3) to rotate. The automatic telescopic rod A (5) extends and pushes the oblique cutter (3) into the rock wall. The drive wheel (29) rotates to make the device move forward along the trench. The oblique cutter (3) moves forward while rotating. The two oblique cutters (3) cut the rock wall one after another and cut out triangular strip rock samples on the surface of the rock wall. S2: As the device moves forward, the cross-cutting blade (11) will move to the triangular long rock sample. The rotating cylinder (12) will drive the two cross-cutting blades (11) to rotate. The automatic telescopic rod B (13) will extend and push out the cross-cutting blade (11). The cross-cutting blade (11) will cut into the long rock sample laterally and stop rotating. The long rock sample will be stuck between the two cross-cutting blades (11). At this time, the automatic telescopic rod B (13) will retract and drive the cross-cutting blade (11) to move backward. When the cross-cutting blade (11) moves backward, it will bring out the long rock sample. S3: When the automatic telescopic rod B (13) retracts, the connecting seat (14) will drive the air supply box (24) to move backward. When the air supply box (24) moves backward, the piston plate (27) will move relative to the air supply box (24), thereby squeezing the air in the air supply box (24). After being squeezed, the air will pass through the air guide groove (22) and be ejected through the exhaust hole (23). The air ejected through the exhaust hole (23) will blow towards the surface of the long rock sample, thereby blowing off the soil and gravel on the surface of the long rock sample. S4: When the cross-cutting blade (11) moves back to its reset position, the rotating cylinder (12) drives the cross-cutting blade (11) to rotate synchronously. When the cross-cutting blade (11) rotates, the long rock sample will rotate to the inside of the hook plate (20). At this time, the automatic telescopic rod B (13) extends and causes the cross-cutting blade (11) to move outward again. The hook plate (20) will cause the long rock sample to fall off. The fallen long rock sample will slide down along the hook plate (20) and the feed plate (19) into the collection box (21) for collection.
