Description

Technical Field

[0001] The present invention relates to the technical field of geological exploration, and in particular to a geological exploration deep rock sampling device and a sampling method. Background Art

[0002] In the process of geological exploration, deep rock sampling is often carried out, and a series of analysis and processing operations are performed on the sampled samples to complete the overall geological exploration operation. In the process of sampling deep rocks, the groove method is mainly used for sampling. First, a cutting machine is used to cut multiple deep grooves on the rock surface, and then other tools are used to pry out the rocks inside the deep grooves. The overall operation is simple; However, in the actual working process, the connection stability between the rock inside the deep groove and the rock body is relatively high. After the deep groove is cut, the staff needs to use great force to pry it, which is a huge workload. At the same time, before the carving operation, in order to reduce the generation of dust, a certain amount of clean water will be sprayed on the surface of the rock. Sometimes, clean water will be sprayed during the carving process. The clean water and the dust generated by the carving are mixed to form a sticky substance scattered on the surface of the rock. These sticky substances have basically no sampling value. On the contrary, they will reduce the cleanliness of the rock. They need to be cleaned manually later. Then, when the deep groove is processed, the trajectories between the deep grooves are not completely the same, which further increases the subsequent prying workload.

[0011] A method for sampling deep rocks in geological exploration comprises the following steps: S1. Determine the sampling direction: Select the thickness direction of the ore body or the direction with the greatest change in mineral quality, and make a simple mark; S2. Carving a deep groove: Place the entire device at one end of the mark, start the motor, and start cutting along the marked path to form a deep groove. At the same time, the side walls of the deep groove are struck to reduce the stability of the connection between the side walls of the deep groove and the rock body.

All the gravel produced will be sorted and collected as sampling samples.

[0012] The beneficial effects of the present invention are: First, during the grooving process, a series of transmission structures drive the conical plate to move back and forth. The conical plate and the inner wall of the deep groove will form a knocking operation on the inner wall of the deep groove, causing a certain amount of shaking, reducing the stability of the rock in the deep groove, and facilitating the subsequent removal of the rock. At the same time, during the carving process, a certain amount of fine gravel will be generated. These fine gravel will fall on the front side of the rotating plate under the obstruction of the baffle and the rotating plate, reducing safety hazards while ensuring the sampling effect. As the conical plate moves back and forth, it also drives the cleaning plate to rotate back and forth. The cleaning plate is located on the surface of the rock, which can form a certain cleaning effect and reduce the workload of subsequent workers; Then, under the action of the square block and the connecting frame, the position of the limit frame can be restricted, especially when the second deep groove is cut, which can effectively prevent the position from shifting during the second groove cutting. At the same time, the square block can be driven to move back and forth, so as to form a second hammering of the cut deep groove, which facilitates the subsequent rock removal operation. In this process, since the diameter of the third gear is larger than that of the second gear, the movement range of the connecting frame is larger than that of the third connecting plate, so that the second hammering of the cut deep groove can be better performed with greater hammering force. Moreover, during this process, the tension sensor sends out a corresponding electrical signal, thereby reminding the corresponding staff. Since the rock inside the deep groove will be taken out after one carving is completed, but sometimes the inside of the deep groove is not completely disconnected from the rock body, the rock inside the deep groove cannot be taken out. After the connecting frame and the rock are against each other, the time of sending out the electrical signal is short, which means that the time when the connecting frame and the inner wall of the carved deep groove are against each other is short, which means that during the second hammering process, the rock inside the carved deep groove and the rock body are disconnected, and the rock can be taken out.

DETAILED DESCRIPTION

[0015] See Figures 1-10 A deep rock sampling device for geological exploration includes a housing 1, a motor 2, and a cutting blade 4. The motor 2 is fixedly mounted on the outside of the housing 1. The output end of the motor 2 is fixedly connected to a rotating shaft 3. The cutting blade 4 is fixedly sleeved on the outside of the rotating shaft 3. First, the staff can hold the handle outside the housing 1 and start the motor 2, which drives the shaft 3 and the cutting blade 4 to rotate and start the chiseling operation. The above are all existing technologies and will not be described in detail. like Figure 4 、 Figure 5 、 Figure 6 , a rocking assembly for cutting rocks is installed on the outside of the shell 1, and the rocking assembly includes a cam 5 fixedly sleeved on the outside of the rotating shaft 3, a first connecting rod 6 is slidably connected in the shell 1, a second connecting plate 14 is fixedly connected to the side wall of the first connecting rod 6, a trapezoidal plate 15 is fixedly connected to the side wall of the second connecting plate 14, a moving frame 11 is slidably connected in the shell 1, a first spring 12 is fixedly connected between the moving frame 11 and the shell 1, a conical plate 7 is slidably connected in the moving frame 11, and the upper side of the conical plate 7 is fixedly connected A first connecting plate 10 is connected, a threaded plate 18 is fixedly connected to the conical plate 7, a threaded rod 19 is threadedly sleeved on the threaded plate 18, a movable plate 20 is rotatably connected to the lower side of the threaded rod 19, and a limit frame 13 is fixedly connected to the outer side of the movable plate 20, a second connecting rod 16 is fixedly connected to the outer side of the housing 1, a rotating plate 8 is rotatably connected to the outer side of the second connecting rod 16, and the rotating plate 8 is slidably connected to the baffle 9 up and down, and a third connecting rod 17 is fixedly connected to the lower side of the baffle 9, and the third connecting rod 17 is fixedly connected to the limit frame 13; First, before performing the chiseling operation, the threaded rod 19 is rotated first. Since the threaded rod 19 and the threaded plate 18 are threadedly connected, and the movable plate 20 and the conical plate 7 are slidably connected up and down, when the threaded rod 19 is rotated, the movable plate 20 will move up and down relative to the conical plate 7 until the position of the movable plate 20 relative to the conical plate 7 meets the working requirements. When the chiseling operation is performed, at the beginning, the conical plate 7 is located on the upper side of the rock, and there is no deep groove on the upper side of the rock. After the cutting knife 4 is started, the movable housing 1 drives the cutting knife 4 to move as a whole to start the chiseling operation. Since the conical plate 7 is located on the rear side of the cutting knife 4, the conical plate 7 enters the deep groove. During the chiseling process, the rotating shaft 3 drives the cam 5 to rotate, the first connecting rod 6 and the cam 5 are offset, and the first connecting rod 6 drives the second connecting plate 14 and the trapezoidal plate 15 to move back and forth relative to the housing 1 as a whole. 1 and the shell 1 are connected for front and back sliding, and under the action of the first spring 12, the trapezoidal plate 15 is always against the moving frame 11. Therefore, in the process of the trapezoidal plate 15 moving back and forth left and right, the moving frame 11 will be always moved forward and backward relative to the shell 1, and at the same time, the first spring 12 is compressed or stretched, and the moving frame 11 drives the conical plate 7 to move back and forth. Since the conical plate 7 is in the deep groove at this time, the conical plate 7 and the inner wall of the deep groove are against each other to form a knocking operation on the inner wall of the deep groove, forming a certain shaking, reducing the stability of the rock in the deep groove, and providing convenience for the subsequent rock removal. At the same time, the limit frame 13 will always be located on the upper side of the rock and against the rock under the action of its own gravity. During the carving process, a certain amount of fine gravel will be generated. These fine gravel will fall on the front side of the rotating plate 8 under the obstruction of the baffle 9 and the rotating plate 8, reducing safety hazards while ensuring the sampling effect.

[0016] like Figure 7 、 Figure 8 , a cleaning assembly for cleaning dust on the rock surface is installed on the side wall of the limit frame 13, and the cleaning assembly includes two fourth connecting rods 21 fixedly mounted on the side wall of the movable plate 20, and the side walls of the two fourth connecting rods 21 are fixedly connected to the same third connecting plate 22, and the third connecting plate 22 is slidably mounted on the lower side of the limit frame 13, and the side wall of the third connecting plate 22 is fixedly connected to the first rack 23. The lower side of the limit frame 13 is rotatably connected to multiple groups of connecting shafts 26, and the outer sides of the multiple groups of connecting shafts 26 are fixedly connected to the first gears 27, which are meshed with the first rack 23, and the outer sides of the multiple groups of connecting shafts 26 are fixedly connected to the cleaning plates 24; First, when the conical plate 7 moves back and forth relative to the limit frame 13, the conical plate 7 drives the movable plate 20 to move back and forth, and the movable plate 20 drives the third connecting plate 22 to move back and forth through the fourth connecting rod 21, and the third connecting plate 22 drives the first rack 23 to move back and forth, and the first rack 23 drives the first gear 27 to rotate back and forth, and the first gear 27 drives the connecting shaft 26 and the cleaning plate 24 to rotate back and forth. Before the carving operation, in order to reduce the generation of dust, a certain amount of clean water will be sprayed on the surface of the rock. Sometimes, clean water will be sprayed during the carving process. The clean water and the dust generated by the carving are mixed to form a sticky substance scattered on the surface of the rock. These sticky substances have basically no sampling value. On the contrary, they will reduce the cleanliness of the rock and will need to be cleaned manually later. At this time, during this process, the cleaning plate 24 rotates back and forth. The cleaning plate 24 is located on the surface of the rock, which can form a certain cleaning effect and reduce the workload of subsequent workers.

[0017] like Figure 7 、 Figure 9 、 Figure 10 , a positioning assembly is installed on the outside of the limit frame 13, the positioning assembly includes a fourth connecting plate 25 fixedly installed on the upper side of the limit frame 13, the lower side of the fourth connecting plate 25 is rotatably connected to the fifth connecting rod 28, the outer side of the fifth connecting rod 28 is fixedly connected to the second gear 29, the side wall of the third connecting plate 22 is fixedly connected to the second rack 32, the second gear 29 and the second rack 32 are meshed, the outer side of the fifth connecting rod 28 is slidably sleeved with the third gear 31, the third gear 31 and the second gear 29 are fixedly connected, the outer side of the third gear 31 is meshed with the third rack 33, the side wall of the third rack 33 is fixedly connected to the fifth connecting plate 34, the side wall of the fifth connecting plate 34 is fixedly connected to the square rod 37, the outer side of the square rod 37 is slidably connected to the slide 40, and the outer side of the slide 40 is fixedly connected to the connecting plate The connecting frame 35 has a square block 36 slidably connected inside the connecting frame 35, and the side wall of the limit frame 13 is fixedly connected to the sixth connecting rod 44, and the outer side of the sixth connecting rod 44 is slidably connected to the sixth connecting plate 43, and the sixth connecting plate 43 is fixedly connected to the connecting frame 35; the outer side of the sixth connecting rod 44 is threadedly sleeved with two sets of limiting nuts 45, and the two sets of limiting nuts 45 are located on both sides of the sixth connecting plate 43. A detection assembly is installed on the outer side of the square rod 37, and the detection assembly includes a first limiting ring 38 fixedly sleeved on the outer side of the square rod 37, and a second limiting ring 46 is also slidably sleeved on the outer side of the square rod 37. The second limiting ring 46 is located between the first limiting ring 38 and the slide 40, and a fourth spring 42 is fixedly connected between the second limiting ring 46 and the first limiting ring 38, and a third spring 41 is fixedly connected between the second limiting ring 46 and the slide 40; First, the tension sensor is a device that converts physical signals into measurable electrical signals for output. Then, after completing the chiseling operation of a deep groove, when it is necessary to chisel a second deep groove, first move the third gear 31 upward to disconnect the third gear 31 and the third rack 33, then rotate the limit nut 45, adjust the limit nut 45 to the upper side of the sixth connecting rod 44, and then move the entire connecting frame 35, adjust the position of the connecting frame 35, so that the connecting frame 35 is located on the upper side of the already chiseled deep groove. At this time, one end of the square block 36 extends into the chiseled deep groove. At this time, when chiseling this deep groove, During the chiseling operation, one end of the square block 36 is located in the deep groove. When chiseling, the distance between the sixth connecting plate 43 and the limiting nut 45 can be observed. If the distance between the sixth connecting plate 43 and the limiting nut 45 is too large, it means that the deep groove trajectory being chiseled at this moment is too different from the deep groove trajectory that has been chiseled, and timely adjustment is required. In this process, the third connecting plate 22 moving back and forth will drive the second gear 29 to rotate, and the second gear 29 drives the third gear 31 to rotate through the fifth connecting rod 28. The third gear 31 drives the third rack 33 to move, and the third rack 33 drives the third rack 33 through the square rod 37 and the slide plate 40. The connecting frame 35 and the square block 36 move back and forth, which can form a secondary hammering of the carved deep groove, providing convenience for the subsequent rock removal operation, and in this process, since the diameter of the third gear 31 is larger than the diameter of the second gear 29, the movement range of the connecting frame 35 is larger than the movement range of the third connecting plate 22, thereby better performing the secondary hammering of the carved deep groove, and the hammering force is greater. Secondly, this process is mainly transmitted by the third spring 41 and the fourth spring 42. When the connecting frame 35 and the inner wall of the carved deep groove are against each other, the connecting frame 35 will stop, but at this time the third rack 33 It is still in motion, so the third spring 41 and the fourth spring 42 will be compressed, and the tension sensor 39 will send out a corresponding electrical signal, thereby reminding the corresponding staff. After one carving is completed, the rock inside the deep groove will be taken out, but sometimes the inside of the deep groove is not completely disconnected from the rock body, and the rock inside the deep groove cannot be taken out. After the connecting frame 35 and the rock are against each other, the time of sending out the electrical signal is short, which means that the time when the connecting frame 35 and the inner wall of the carved deep groove are against each other is short, which means that during the second hammering process, the rock inside the carved deep groove and the rock body are disconnected, and the rock can be taken out.

[0018] A method for sampling deep rocks in geological exploration comprises the following steps: S1. Determine the sampling direction: Select the thickness direction of the ore body or the direction with the greatest change in mineral quality, and make a simple mark; S2. Carving a deep groove: Place the entire device at one end of the mark, start motor 2, and start cutting along the marked path to form a deep groove. At the same time, the side walls of the deep groove are struck to reduce the stability of the connection between the side walls of the deep groove and the rock body. S3, removing the gravel generated by cutting inside the deep groove; S3, continue to start the motor 2, repeat the cutting operation, process multiple deep grooves, and knock the side walls of the deep grooves again to further reduce the stability between the side walls of the deep grooves and the rock body; S3. All the gravel produced will be sorted and collected as sampling samples.

[0019] In the present invention, when sampling operation is required, the specific operation is as follows: first, determine the sampling direction, then start to chisel the long groove, start the motor 2, the motor 2 drives the rotating shaft 3 and the cutting knife 4 to rotate, and start the chiseling operation. When the chiseling operation is performed, at the beginning, the conical plate 7 is located on the upper side of the rock, and there is no deep groove on the upper side of the rock. After the cutting knife 4 is started, the movable shell 1 drives the cutting knife 4 to move as a whole to start the chiseling operation. Since the conical plate 7 is located on the rear side of the cutting knife 4, the conical plate 7 enters the deep groove. During the chiseling process, the rotating shaft 3 drives the cam 5 to rotate, the first connecting rod 6 and the cam 5 are offset, and the first connecting rod 6 drives the second connecting plate 14 and the trapezoidal plate 15 to move back and forth relative to the shell 1 as a whole. Since the movable frame 11 and the shell 1 are connected for front and back sliding, and in the first elastic The first spring 12 is compressed or stretched, and the moving frame 11 drives the conical plate 7 to move back and forth. At this time, the conical plate 7 is located in the deep groove, and the conical plate 7 and the inner wall of the deep groove are pressed against each other to form a knocking operation on the inner wall of the deep groove, thereby forming a certain shaking, reducing the stability of the rock in the deep groove, and facilitating the subsequent removal of the rock. At the same time, the limit frame 13 will always be located on the upper side of the rock and press against the rock under the action of its own gravity. In the process of carving, a certain amount of fine crushed stones will be generated. These fine crushed stones will fall on the front side of the rotating plate 8 under the obstruction of the baffle 9 and the rotating plate 8, reducing safety hazards while ensuring the sampling effect. When the conical plate 7 moves back and forth relative to the limit frame 13, the conical plate 7 drives the movable plate 20 to move back and forth, and the movable plate 20 drives the third connecting plate 22 to move back and forth through the fourth connecting rod 21, and the third connecting plate 22 drives the first rack 23 to move back and forth, and the first rack 23 drives the first gear 27 to rotate back and forth, and the first gear 27 drives the connecting shaft 26 and the cleaning plate 24 to rotate back and forth. Before the chiseling operation, in order to reduce the generation of dust, a certain amount of clean water is sprayed on the surface of the rock. Sometimes, clean water is sprayed during the chiseling process. The clean water and the dust generated by the chiseling are mixed to form a sticky substance scattered on the surface of the rock. These sticky substances basically have no sampling value. On the contrary, they will reduce the cleanliness of the rock. Later, manual cleaning is required. At this time, during this process, the cleaning plate 24 rotates back and forth. The cleaning plate 24 is located on the surface of the rock, which can form a certain cleaning effect and reduce the workload of subsequent workers. After completing the chiseling operation of one deep groove, when it is necessary to chisel the second deep groove, first move the third gear 31 upward to disconnect the third gear 31 and the third rack 33, then rotate the limit nut 45, adjust the limit nut 45 to the upper side of the sixth connecting rod 44, and then move the connecting frame 35 as a whole, adjust the position of the connecting frame 35, so that the connecting frame 35 is located on the upper side of the chiseled deep groove. At this time, one end of the square block 36 extends into the chiseled deep groove. At this time, when chiseling this deep groove, one end of the square block 36 is located in the deep groove, and when chiseling, it can Observe the distance between the sixth connecting plate 43 and the limiting nut 45. If the distance between the sixth connecting plate 43 and the limiting nut 45 is too large, it means that the deep groove trajectory being chiseled at this moment is too different from the deep groove trajectory that has been chiseled. Timely adjustment is required. In this process, the back-and-forth moving third connecting plate 22 drives the second gear 29 to rotate. The second gear 29 drives the third gear 31 to rotate through the fifth connecting rod 28. The third gear 31 drives the third rack 33 to move. The third rack 33 drives the connecting frame 35 and the square block 36 back and forth through the square rod 37 and the slide 40. The movement of the third gear 31 can form a secondary hammering of the carved deep groove, which provides convenience for the subsequent rock removal operation, and in this process, since the diameter of the third gear 31 is larger than the diameter of the second gear 29, the movement range of the connecting frame 35 is larger than the movement range of the third connecting plate 22, thereby better performing the secondary hammering of the carved deep groove, and the hammering force is greater. Secondly, this process is mainly transmitted by the third spring 41 and the fourth spring 42. When the connecting frame 35 and the inner wall of the carved deep groove are against each other, the connecting frame 35 will stop, but the third rack 33 is still in motion at this time. state, thereby compressing the third spring 41 and the fourth spring 42, and the sensor sends a corresponding electrical signal, thereby reminding the corresponding staff. Since the rock inside the deep groove will be taken out after one carving is completed, but sometimes the inside of the deep groove is not completely disconnected from the rock body, the rock inside the deep groove cannot be taken out. After the connecting frame 35 and the rock are against each other, the time of sending the electrical signal is short, which means that the time when the connecting frame 35 and the inner wall of the carved deep groove are against each other is short, which means that during the second hammering process, the rock inside the carved deep groove and the rock body are disconnected, and the rock can be taken out.
