Description

Technical Field

[0001] This invention relates to the field of mine filling technology, and in particular to a flocculant addition device for mine tailings trough filling. Background Technology

[0002] During mining operations, disturbances caused by mining activities may lead to rock deformation, damage to the internal structure of the mine, and increased risk of collapse accidents. Mine backfilling technology has been proven to be an effective means of controlling surrounding rock deformation and is currently widely used.

[0003] Tailings slurry used for mine backfilling typically requires the addition of flocculants for flocculation during preparation. Currently, commonly used flocculants are inorganic flocculant powders, which need to be prepared into flocculant solutions before use. Complete mixing of the flocculant powder with the water is crucial. Currently, flocculants are added using a simple closed-loop pipeline method. Because the flocculant contains many flocs, clogging of the pores frequently occurs during operation, leading to unstable flocculant addition. Furthermore, the fixed addition range of the flocculant reduces its contact reaction with tailings slurry particles, thus diminishing its practicality. Therefore, we provide a flocculant addition device for mine backfill tailings troughs to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by proposing a method that facilitates two-layer filtration of the added flocculant and allows for timely cleaning of the filtration mechanism during filtration, thus avoiding blockage and ensuring continuous addition of flocculant.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flocculant addition device for filling tailings troughs in mines includes a storage tank 1, a tank cover 2 installed at the upper end of the storage tank 1, a feed pipe 3 connected to the upper end of the tank cover 2, a water pump 7 installed at the upper end of the tank cover 2, a suction pipe 8 passing through the tank cover 2 and extending into the inner cavity of the storage tank 1 on one side of the water pump 7, a matching filter cover 27 provided at the lower end of the tank cover 2, and a feed pipe 9 on one side of the water pump 7 used to introduce flocculant into a mixing tank.

[0007] The outer diameter of the liquid storage tank 1 is equipped with a slag discharge pipe 5, and the outer diameter of the slag discharge pipe 5 is equipped with a gate valve 4. The upper end of the tank cover 2 is provided with a slot, and the bottom end of the inner cavity of the liquid storage tank 1 is provided with a slot. The inner cavity of the slot is provided with a top plate 31, and the inner cavity of the slot is provided with a bottom plate 30. A filter screen 15 is provided between the bottom plate 30 and the top plate 31. The filter screen 15 is installed at an angle and forms an inverted trapezoid with the liquid storage tank 1. The narrow and wide top of the inverted trapezoid is located at the bottom of the liquid storage tank 1 and is adjacent to the slag discharge pipe 5.

[0008] A servo motor 6 is installed on the upper end of the cover 2, and a third rotating shaft 24 is connected to the lower end of the servo motor 6. A push rod 28 matching the position of the filter screen 15 is fixed on the third rotating shaft 24. The servo motor 6 is also coupled to the first rotating shaft 20 through the engine belt 21. A push rod 28 matching the position of the filter screen 15 is fixed on the first rotating shaft 20. The first rotating shaft 20 and the third rotating shaft 24 are located on both sides of the filter screen 15, and the push rod 28 on the first rotating shaft 20 and the push rod 28 on the third rotating shaft 24 are staggered and used to impact non-overlapping points on the filter screen 15.

[0009] The lower end of the cover 2 is connected to a second rotating shaft 23. A second gear 29 is installed at the lower end of the outer diameter of the second rotating shaft 23. A first gear 25 meshes with the outer diameter of the third rotating shaft 24. A guide ring 39 is sleeved on the outer diameter of the second rotating shaft 23. A scraper sleeve 26 is connected to one side of the guide ring 39 via a connecting rod 38. A guide head 391 is elastically provided on the inner wall of the guide ring 39. The guide head 391 is used to couple with the guide grooves 231, 232, 233, 234 provided on the outer wall of the second rotating shaft 23. Thus, during the rotation of the second rotating shaft 23, the scraper sleeve 26 moves up and down relative to the filter cover 27 through the sliding movement between the guide grooves 231, 232, 233, 234 and the guide head.

[0010] Among them, the push rod 28 on the third rotating shaft 24 is set on the third rotating shaft 24 and close to the bottom side of the liquid storage tank 1, and is set in L shape; then, when the L-shaped push rod 28 on the third rotating shaft 24 and the third rotating shaft 24 together form a concave area, the filter cover cleaning assembly composed of the second rotating shaft 23, the scraper sleeve 26, the filter cover 27 and the guide rail ring 39 are arranged between the concave areas.

[0011] Preferably, the push rod 28 on the third rotating shaft 24 includes a first push rod 281 and a second push rod 282, and the push rod 28 on the first rotating shaft 20 includes a third push rod 283 and a fourth push rod 284;

[0012] The first push rod 281, the second push rod 282, the third push rod 283 and the fourth push rod 284 correspond to the four impact points set from high to low on the filter screen 15.

[0013] Preferably, the first push rod 281 and the second push rod 282 are located on both sides of the third rotating shaft 24, and the first push rod 281 and the second push rod 282 will hit the filter screen 15 once for each rotation of the third rotating shaft 24.

[0014] The third push rod 283 and the fourth push rod 284 are respectively located on one side of the first rotating shaft 20, and the rod body of the third push rod 283 and the rod body of the fourth push rod 284 form an angle of 90°; in addition, a gear set 10 is provided between the first rotating shaft 20 and the engine belt 21, and the gear set 10 is used to convert the rotational torque transmitted from the engine belt 21 into a periodic clockwise and counterclockwise alternating rotational torque on the first rotating shaft 20.

[0015] Preferably, the gear set 10 includes a main drive gear 11, a first core gear 12, a second core gear 13, and a secondary drive gear 14, specifically:

[0016] The shaft 22 of the main drive gear 11 is directly connected to the engine belt 21 for transmission.

[0017] The first composite gear 12 and the second composite gear 13 have the same structure. Their toothed surfaces are divided into two parts along the vertical plane of their central shaft: a first gear ring and a second gear ring. The first gear ring is a full circle of teeth, and the second gear ring is a half circle of teeth.

[0018] The first composite gear 12 and the second composite gear 13 are disposed on both sides of the main drive gear 11, and the first gear ring of the first composite gear 12 and the first gear ring of the second composite gear 13 are coupled to the main drive gear 11. Therefore, during the rotation of the main drive gear 11, the first composite gear 12 and the second composite gear 13 are driven to rotate in one direction respectively.

[0019] The secondary transmission gear 14 is disposed between the first core gear 12 and the second core gear 13. The second gear rings of the first core gear 12 and the second gear rings of the second core gear 13 are coupled to the secondary transmission gear 14 in a staggered manner. Therefore, when the first core gear 12 drives the secondary transmission gear 14 to rotate in the first direction, the blank area in the second gear ring of the second core gear 13 is idle with the secondary transmission gear 14. Furthermore, when the second core gear 13 drives the secondary transmission gear 14 to rotate in the opposite direction of the first direction, the blank area in the second gear ring of the first core gear 12 is idle with the secondary transmission gear 14.

[0020] In this configuration, one of the first core gear 12 and the second core gear 13 is in a driving state with the secondary transmission gear 14, while the other is in an idle state; when one switches from the driving state to the idle state, the other switches from the idle state to the driving state, and so on.

[0021] Preferably, a guide head 391 is elastically provided on the inner wall of the guide ring 39. The guide head 391 is used to couple with the guide grooves 231, 232, 233, and 234 provided on the outer wall of the second rotating shaft 23, specifically including:

[0022] The guide rail groove on the outer wall of the second rotating shaft 23 is divided into two sections. The first section spirals upward and the second section spirals downward. The depth of the limiting groove in the first section and the depth of the limiting groove in the second section are staggered. The connection between the top of the first section and the top of the second section, as well as the connection between the bottom of the first section and the bottom of the second section, are respectively connected by a ramp to connect the limiting grooves of different depths.

[0023] This allows the guide head 391 to transition from a first spiral ascent to a second spiral descent during its confined movement within the guide groove. Furthermore, at the intersection of the first and second spiral sections in the guide groove, the depths can be staggered to ensure that the movement of the guide head 391 at the intersection of the first and second spiral sections does not interfere with each other.

[0024] Preferably, the filter screen 15 is provided with a first impact block 16, a second impact block 17, a third impact block 18 and a fourth impact block 19 at the four impact points in sequence;

[0025] Preferably, the bottom plate 30 and the top plate 31 are provided with a movable groove 35 on the corresponding side. The inner cavity of the movable groove 35 is connected to both sides of a spring 36. The corresponding side of the spring 36 is connected to a mounting rod 34. The mounting rod 34 is connected to the filter screen 15.

[0026] Preferably, the bottom plate 30 and the top plate 31 are provided with a sliding groove 33 on the corresponding side, and one end of the mounting rod 34 is connected to a slider 32 that slides with it.

[0027] Preferably, the outer diameter of the scraper sleeve 26 matches that of the filter cover 27, and the inner side of the scraper sleeve 26 is provided with a frosted surface. Furthermore, the filter screen is installed at an angle, and the filter screen is made of a corrosion-resistant material.

[0028] The present invention provides a flocculant addition device for filling tailings troughs in mines, which has the following advantages:

[0029] The servo motor 6 drives the push rod 28 to rotate via the rotating shaft, which facilitates the intermittent rightward push of the filter screen 15. This allows the filter screen 15 to compress the spring 36 while moving stably. The intermittent impact of the push rod 28 and the rebound of the spring 36 help to remove the flocculation from the filter screen 15, preventing it from sticking to the filter screen 15 and causing blockage, which would affect the continuous addition of flocculant. At the same time, the third rotating shaft 24 drives the second bevel gear 29 to rotate via the first gear 25. The rotation of the second rotating shaft 23 inside the second gear 29 causes the guide ring 39 screwed to its outer diameter to move up and down. In turn, the guide ring 39 drives the scraper sleeve 26 to scrape up and down via the connecting rod, which helps to remove the fine flocculation adsorbed on the surface of the filter cover 27, preventing the filter cover 27 from becoming blocked and affecting the continuous addition of flocculant, thus effectively improving the flocculant addition efficiency.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0045] This invention provides a flocculant addition device for filling tailings troughs in mines, such as... Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the system includes a storage tank 1, a tank cover 2 installed at the upper end of the storage tank 1, a feed pipe 3 connected to the upper end of the tank cover 2, a water pump 7 installed at the upper end of the tank cover 2, a suction pipe 8 passing through the tank cover 2 and extending into the inner cavity of the storage tank 1 on one side of the water pump 7, a matching filter cover 27 provided at the lower end of the tank cover 2, and a feed pipe 9 on one side of the water pump 7 used to introduce flocculant into a mixing tank.

[0046] The outer diameter of the liquid storage tank 1 is fitted with a slag discharge pipe 5, and the outer diameter of the slag discharge pipe 5 is fitted with a gate valve 4. The upper end of the tank cover 2 has a slot, and the bottom end of the inner cavity of the liquid storage tank 1 has a retaining groove. Figure 8 As shown, the inner cavity of the slot is provided with a top plate 31, and the inner cavity of the slot is provided with a bottom plate 30. A filter screen 15 is provided between the bottom plate 30 and the top plate 31. The filter screen 15 is installed at an angle and forms an inverted trapezoid with the liquid storage tank 1 (with... Figure 1 and Figure 2 For example, the corresponding trapezoid is specifically an inverted right trapezoid; however, in actual implementation, there are also cases where the corresponding liquid storage tank 1 is circular. Therefore, the trapezoid here should be understood in more cases as similar to... Figure 2The interface shown is more appropriately an inverted trapezoid; wherein, the narrow and wide top of the inverted trapezoid is located at the bottom of the liquid storage tank 1 and is adjacent to the slag discharge pipe 5;

[0047] A servo motor 6 is installed on the upper end of the cover 2, and a third rotating shaft 24 is connected to the lower end of the servo motor 6. A push rod 28 matching the position of the filter screen 15 is fixed on the third rotating shaft 24. The servo motor 6 is also coupled to the first rotating shaft 20 through the engine belt 21. A push rod 28 matching the position of the filter screen 15 is fixed on the first rotating shaft 20. The first rotating shaft 20 and the third rotating shaft 24 are located on both sides of the filter screen 15, and the push rod 28 on the first rotating shaft 20 and the push rod 28 on the third rotating shaft 24 are staggered and used to impact non-overlapping points on the filter screen 15.

[0048] The lower end of the box cover 2 is connected to a second rotating shaft 23. A second gear 29 is installed at the lower end of the outer diameter of the second rotating shaft 23. A first gear 25 meshes with the outer diameter of the third rotating shaft 24. A guide ring 39 is sleeved on the outer diameter of the second rotating shaft 23. A scraper sleeve 26 is connected to one side of the guide ring 39 via a connecting rod 38. A guide head 391 is elastically provided on the inner wall of the guide ring 39. The guide head 391 (in a preferred embodiment, such as...) Figure 9 As shown, a spring 393 and a spring 393 fixing plate 392 can also be provided for the guide rail head 391 to ensure more stable elastic expansion and contraction of the guide rail head 391 on the inner wall of the guide rail ring 39. This is used to connect with the guide rail groove provided on the outer wall of the second rotating shaft 23 (see schematic diagram for reference). Figure 12 and Figure 13 The symbols 231, 232, 233, and 234 in the diagram are coupled together, so that during the rotation of the second rotating shaft 23, the guide rail groove (a schematic illustration can be found in the diagram) is used for coupling. Figure 12 and Figure 13 The movement of the slide rail between the markings 231, 232, 233, 234 and the guide rail head causes the scraper sleeve 26 to reciprocate up and down relative to the filter cover 27.

[0049] Among them, the push rod 28 on the third rotating shaft 24 is set on the third rotating shaft 24 and close to the bottom side of the liquid storage tank 1, and is set in L shape; then, when the L-shaped push rod 28 on the third rotating shaft 24 and the third rotating shaft 24 together form a concave area, the filter cover cleaning assembly composed of the second rotating shaft 23, the scraper sleeve 26, the filter cover 27 and the guide rail ring 39 are arranged between the concave areas.

[0050] This invention proposes a flocculant addition device for filling tailings troughs in mines. A servo motor 6 drives a top rod 28 to rotate via a rotating shaft, intermittently pushing the filter screen 15 to the right. This allows the filter screen 15 to compress the spring 36 while moving stably. The intermittent impact of the top rod 28 and the rebound of the spring 36 effectively remove flocculants from the filter screen 15, preventing them from adhering and clogging, thus ensuring continuous flocculant addition. Simultaneously, a third rotating shaft 24 drives a second bevel gear 29 to rotate via a first gear 25. The rotation of the second shaft 23 within the second gear 29 causes the guide ring 39, screwed to its outer diameter, to move up and down. The guide ring 39, through a connecting rod, drives a scraper sleeve 26 to scrape up and down, effectively removing small flocculants adsorbed on the surface of the filter cover 27, preventing clogging and ensuring continuous flocculant addition, thus significantly improving the flocculant addition efficiency.

[0051] In embodiments of the present invention, such as Figure 8 As shown, in a preferred implementation, the bottom plate 30 and the top plate 31 are each provided with a movable groove 35 on their corresponding sides. Springs 36 are connected to both sides of the inner cavity of each movable groove 35, and mounting rods 34 are connected to the corresponding sides of each spring 36. The mounting rods 34 are all connected to the filter screen 15. This design aims to produce a better shaking effect after the filter screen 15 is impacted. In actual implementation, this preferred implementation may not be used, since a filter screen 15 made of elastic material can achieve a good shaking effect after forming a good shape. However, the advantages of this preferred solution are obvious: it can improve the service life of the filter screen and maintain the consistency of the shaking effect after impact. Furthermore, the bottom plate 30 and the top plate 31 can also be provided with sliding grooves 33 on their corresponding sides, and one end of each mounting rod 34 can be connected to a sliding block 32 that slides with it.

[0052] On the other hand, the outer diameter of the scraper sleeve 26 matches that of the filter cover 27, and the inner side of the scraper sleeve 26 is provided with a frosted surface. Furthermore, the filter screen is installed at an angle, and the filter screen is made of a corrosion-resistant material.

[0053] To achieve a more thorough and effective removal of the lint adhering to the filter screen 15, the frequency of impact on the filter screen 15 is crucial. Therefore, this invention also provides a preferred improvement scheme, such as... Figure 4 As shown, the push rod 28 on the third rotating shaft 24 includes a first push rod 281 and a second push rod 282, and the push rod 28 on the first rotating shaft 20 includes a third push rod 283 and a fourth push rod 284;

[0054] The first push rod 281, the second push rod 282, the third push rod 283 and the fourth push rod 284 correspond to the four impact points set from high to low on the filter screen 15.

[0055] The reason for assigning the corresponding push rods to the third rotating shaft 24 and the first rotating shaft 20 is that the corresponding filter screen 15 is placed at an angle. Furthermore, in the device of the present invention, a second rotating shaft 23, a scraper sleeve 26, and a filter cover 27 are also provided near the third rotating shaft 24. This would cause obstruction and problems for the corresponding push rods to be placed on the third rotating shaft 24. Therefore, after research, it was found that in the structural scenario set by the present invention, it is a necessary process to place the corresponding push rods on both sides of the filter screen 15. Moreover, in the subsequent further optimization scheme of the present invention, unexpected additional effects will be produced.

[0056] Another extremely important beneficial effect exists in the invention, such as Figure 2 The characteristic shown is that the first push rod 281 and the second push rod 282 rotate around the filter cover 27. This unique design allows the impurities scraped off by the reciprocating motion of the scraper sleeve 26 relative to the filter cover 27 to be further carried to the filter screen 15 side by the circumferential motion of the L-shaped first push rod 281 and the second push rod 282, and then discharged through the slag discharge pipe 5. This also reduces the severity of impurity accumulation on the filter cover 27. An implicit condition is that the impurities scraped off the filter cover 27 can pass through the filter screen 15 and reach the slag discharge pipe 5.

[0057] The advantage of this oblique placement is that the corresponding vibration of the flocs will be concentrated in a smaller area near the slag discharge pipe 5, thus making the slag discharge process more efficient (it can be understood that the density of the flocs near the slag discharge pipe 5 will be higher than that of the filter screen 15 when it is placed vertically).

[0058] In embodiments of the present invention, such as Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the first push rod 281 and the second push rod 282 are located on both sides of the third rotating shaft 24. When the third rotating shaft 24 rotates one revolution, the first push rod 281 and the second push rod 282 will hit the filter screen 15 once.

[0059] like Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, the third push rod 283 and the fourth push rod 284 are respectively located on one side of the first rotating shaft 20, and the rod body of the third push rod 283 and the rod body of the fourth push rod 284 form an angle of 90°; in addition, a gear set 10 is provided between the first rotating shaft 20 and the engine belt 21, and the gear set 10 is used to convert the rotational torque transmitted from the engine belt 21 into a periodic clockwise and counterclockwise alternating rotational torque on the first rotating shaft 20.

[0060] In order to proceed with the corresponding Figure 3 , Figure 5 , Figure 6 and Figure 7 The presented state is easy to describe. The filter 15 is pre-marked with a first impact block 16, a second impact block 17, a third impact block 18, and a fourth impact block 19 sequentially arranged at the four impact points (wherein...). Figure 2 and Figure 4 All of them have been labeled.

[0061] In an example embodiment of the present invention, Figure 3 In response Figure 2 The diagram shown only illustrates the effect of the first rotating shaft 20, the third rotating shaft 24, the first push rod 281, the second push rod 282, the third push rod 283, and the fourth push rod 284, as well as the impact points in the matching filter screen 15. Figure 5 In response Figure 4 The diagram shown only illustrates the effect of the first rotating shaft 20, the third rotating shaft 24, the first push rod 281, the second push rod 282, the third push rod 283, and the fourth push rod 284, as well as the impact points in the matching filter screen 15. Figure 3 and Figure 5 A comparison reveals that when the second push rod 282 collides with the second impact block 17, the other three push rods are all far from their respective impact blocks. Furthermore, from... Figure 3 The rotation direction of the pivot indicated in the diagram, and the matching... Figure 5 The present is immediately Figure 3 In the next round of impact, it's easy to see that after the second push rod 282 rotates 90° counterclockwise, the third push rod 283 immediately impacts the third impact block 18 counterclockwise. Then, in the continuous process, it will further transition to... Figure 6 As shown in the process, the corresponding first push rod 281 will move from... Figure 3 Rotate counterclockwise to Figure 6 The indicated position allows for impact against the first impact block 16, while the corresponding third and fourth push rods 283 and 284 rotate clockwise. Then, in the continuous process, it further transitions to... Figure 7 As shown in the process, the corresponding first push rod 281 will move from... Figure 6 Rotate counterclockwise to Figure 7 At the indicated position, the corresponding third push rod 283 will rotate clockwise and strike the third impact block 18. Furthermore, in the subsequent process, the corresponding third push rod 283 and fourth push rod 284 will... Figure 7 and Figure 5 It swings back and forth between the two states.

[0062] It should be noted that the 90° mentioned above is only a preferred angle in the implementation of this invention. In specific implementations, other angles such as 120°, 60°, and any angle between these angles can also be used. The advantage of choosing 90° is that it can compress the surplus space on the right side of the corresponding first rotating shaft 20 to the extreme, which can further compress the top width of the corresponding inverted trapezoid, thereby further improving the slag discharge efficiency of the slag discharge pipe 5.

[0063] In the implementation of the embodiments of the present invention, theoretically no design is required. Figure 3 , Figure 5 , Figure 6 and Figure 7 The pendulum structure exhibited in the process, including the third push rod 283 and the fourth push rod 284, can be directly solved using a circular rotation solution similar to the first push rod 281 and the second push rod 282. However, as analyzed above, the preferred solution of the present invention can further compress the inverted trapezoidal top size formed by the liquid storage tank 1 and the filter screen 15, thereby further optimizing the slag discharge effect (intuitively speaking, increasing the content of flocs in the slag discharge). For this purpose, the embodiment of the present invention also provides a gear set 10 to complete the above-mentioned pendulum process. Figure 10 and Figure 11 For further reference Figure 2 The front view, in which, Figure 10 In response Figure 2 The diagram shows a bottom view of the gear set 10, that is, a structural effect of the gear set 10 viewed from the surface of the cover 2 facing upwards. Figure 11 For the corresponding Figure 2 The diagram shows a top view of the gear set 10. The gear set 10 includes a main drive gear 11, a first core gear 12, a second core gear 13, and a secondary drive gear 14. Specifically:

[0064] The shaft 22 of the main drive gear 11 is directly connected to the engine belt 21 for transmission.

[0065] The first composite gear 12 and the second composite gear 13 have the same structure. Their toothed surfaces are divided into two parts along the vertical plane of their central shaft: a first gear ring and a second gear ring. The first gear ring is a full circle of teeth, and the second gear ring is a half circle of teeth.

[0066] The first composite gear 12 and the second composite gear 13 are disposed on both sides of the main drive gear 11, and the first gear ring of the first composite gear 12 and the first gear ring of the second composite gear 13 are coupled to the main drive gear 11. Therefore, during the rotation of the main drive gear 11, the first composite gear 12 and the second composite gear 13 are driven to rotate in one direction respectively.

[0067] The secondary transmission gear 14 is disposed between the first core gear 12 and the second core gear 13. The second gear rings of the first core gear 12 and the second gear rings of the second core gear 13 are coupled to the secondary transmission gear 14 in a staggered manner. Therefore, when the first core gear 12 drives the secondary transmission gear 14 to rotate in the first direction, the blank area in the second gear ring of the second core gear 13 is idle with the secondary transmission gear 14. Furthermore, when the second core gear 13 drives the secondary transmission gear 14 to rotate in the opposite direction of the first direction, the blank area in the second gear ring of the first core gear 12 is idle with the secondary transmission gear 14.

[0068] In this configuration, one of the first core gear 12 and the second core gear 13 is in a driving state with the secondary transmission gear 14, while the other is in an idle state; when one switches from the driving state to the idle state, the other switches from the idle state to the driving state, and so on.

[0069] To demonstrate the effects of the corresponding first and second gear rings, Figure 10 When drawing the corresponding first and second composite gears 12 and 13, a certain axial view angle was deliberately introduced for both. Figure 10 It is not difficult to see that the teeth on the surfaces of the first composite gear 12 and the second composite gear 13 are their respective second gear rings, and, with Figure 10 As shown, when the main drive gear 11 rotates clockwise, the first and second composite gears 12 and 13 will both rotate clockwise under the drive of the main drive gear 11. Furthermore, the second gear ring of the second composite gear 13 will engage with the gear ring of the secondary drive gear 14, while the second gear ring of the first composite gear 12 will remain in an idle state (i.e.,...). Figure 10 The second gear ring of the first composite gear 12 shown in the image has no teeth (as indicated by the smooth semicircular portion). Figure 10 The gear set state shown can be mapped to: Figure 5 Just switched to Figure 6 The state of the change process.

[0070] To further demonstrate the principle and mechanism of the vertical movement of the guide ring 39 proposed in this invention, the following will be conducted through... Figure 12 , Figure 13 , Figure 14 and Figure 9 A detailed explanation is provided, specifically including:

[0071] The guide groove on the outer wall of the second rotating shaft 23 is divided into two sections. The first section spirals upward (in... Figure 12 (marked with an upward arrow in the middle), the second section spirals downward (in...) Figure 12 (This is marked with a downward arrow in the text), and the depths of the limiting grooves in the first and second segments are staggered (see reference). Figure 13 The depth difference is presented); at the junction of the top of the first segment and the top of the second segment, and at the junction of the bottom of the first segment and the bottom of the second segment, the limiting grooves with different depths are connected together by a ramp (see reference). Figure 14 (The structure shown). In Figure 12 The schematic diagram of the limiting groove trajectory after the second rotating shaft 23 is flattened is shown. Rolling it up will restore the limiting groove trajectory on the surface of the second rotating shaft 23. The connection relationships between the corresponding trajectories are marked with ①, ②, ③, ④, and ⑤ respectively in the diagram. Figure 12 The lines with corresponding numbers on the left and the lines with corresponding numbers on the right are connected when rolled up.

[0072] This allows the guide head 391 to transition from a first spiral ascent to a second spiral descent during its confined movement within the guide groove. Furthermore, at the intersection of the first and second spiral sections in the guide groove, the depths can be staggered to ensure that the movement of the guide head 391 at the intersection of the first and second spiral sections does not interfere with each other.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
