Abstract
Description
Technical Field
[0001] This invention relates to the field of metallurgical technology, specifically to a mud scraping structure of a mud-removing mechanism and its mud-cleaning method. Background Technology
[0002] With the development of blast furnace smelting technology, the process requirements, operating conditions, and raw materials for hydraulic mud guns in front of the furnace have changed. As a result, the operating conditions of the mud gun's mud-making mechanism have also changed. Currently, the operating conditions of the mud gun equipment in front of the furnace are characterized by increased usage frequency, changes in mud condition, and increased process parameters. With adjustments made to all these factors, the operation of the mud gun's mud-making mechanism is now subject to higher requirements.
[0003] To achieve a one-time welding of the mud-dispensing cylinder and eliminate the need for reprocessing the mud plug each time, thus saving on the manufacturing and installation costs of the mud plug, a hydraulic mud-dispensing mechanism (see patent number: 200920128391.X) has been developed. This mechanism includes a mud-dispensing cylinder and a mud plug assembly. The mud plug assembly comprises a mud-dispensing cylinder, a pressure plate, a nylon ring, and a cast iron ring. The pressure plate is fixed to one end of the mud-dispensing cylinder with screws. A retaining ring is fixedly fitted onto the end of the mud-dispensing cylinder near the pressure plate. The nylon ring and cast iron ring fit into the annular groove formed by the retaining ring and the pressure plate. This invention replaces the original mud plug with a retaining ring, which is welded to the mud-dispensing cylinder in one go, eliminating the need for reprocessing the mud plug each time and saving on the manufacturing and installation costs of the mud plug. Each time, only the newly processed nylon ring and cast iron ring need to be replaced according to the wear condition of the inner wall of the mud-dispensing cylinder, greatly reducing the amount of maintenance required by workers.
[0004] However, the existing mud scraping mechanism has limited support for the mud-scraping cylinder. When factors such as the hardness of the mud and the assembly clearance of the mud plug ring change, the force exerted by the mud plug ring in the mud plug at the front end of the mud-scraping cylinder increases significantly. This can easily lead to excessive mud return, deformation of the mud plug pressure plate, or other failures, ultimately causing the mud-scraping mechanism to become unstable or unusable. Furthermore, the installation and support structures at the middle and front ends of the mud scraper ring and mud plug are also prone to scratches on the inner wall of the mud cylinder or the outer diameter of the cylinder body during the reciprocating operation of the mud-scraping cylinder, thus reducing its service life to some extent.

[0013] As a further embodiment of the present invention: the mud scraper ring is made of steel, and one end of the mud scraper ring has a double-blade structure. Different gaps are formed between the mud scraper ring and the mud-removing cylinder. The mud scraper ring and the self-lubricating copper sleeve are fitted with an interference fit. The mud scraper ring is fixedly connected to the drive cavity by bolts.
[0014] As a further embodiment of the present invention: the mud scraper ring is axially and radially clamped onto the inner wall of the gun body assembly by a fixing ring, and an inclined surface is provided between the inner hole of the fixing ring and the mud scraper ring, and the included angle of inclination of the inclined surface is greater than 90°.
[0015] As a further embodiment of the present invention: the sludge scraper ring is located outside the sludge-removing cylinder and is movably connected to the sludge-removing cylinder; the axial direction of the sludge scraper ring is held and positioned by a fixed ring; and the radial direction of the sludge scraper ring is engaged with the drive cavity to achieve positioning connection.
[0016] As a further aspect of the present invention: the mud-cleaning method of the mud-scraping structure of the mud-removing mechanism specifically includes the following steps: Step 1: When the mud-discharging cylinder moves forward, it drives the mud-discharging plug assembly forward, thereby squeezing the mud in the mud cylinder into the taphole channel. Step 2: During operation, some of the gunning mud will enter the side of the gunning cylinder through the gap between the gunning plug and the steel. At the same time, some gunning mud may also adhere to the inner wall of the cylinder. When the gunning cylinder retracts, this returned mud will obstruct the retracted gunning plug and the gunning cylinder, forming resistance. Step 3: A new type of mud-dissolving plug and scraper ring are adopted. The self-lubricating copper sleeve in the scraper ring provides good support for the operation of the mud-dissolving cylinder. Step four: During the retraction of the mud-removing cylinder, the piston sleeve of the mud-removing piston cleans the residual mud on the inner wall of the mud cylinder, and the mud scraper ring cleans the returned mud flowing into the mud-removing cylinder. Through its structural fit and size setting, it has a certain guiding effect on the waste gun mud, so that it can be discharged from the mud leakage hole set on the drive cavity during the process, ensuring the reliability of the mud-removing mechanism in mud-removing operation. Step 5: After the mud material exits from the discharge nozzle, some residual material will remain on the discharge nozzle. When processing the residual material, the motor rotates clockwise under the action of electricity, directly driving the drive disc to rotate. As the drive disc rotates, it carries the first rotating shaft around the center point of the drive disc and directly acts on the drive rod. At the same time, since the other end of the drive rod is directly rotatably connected to the fixed frame, the drive rod can rotate around the first rotating shaft and the second rotating shaft as the base point along the movement trajectory of the first rotating shaft. Since the length of the drive rod remains unchanged, in order to ensure the conservation of force, it can directly push the fixed frame and the push rod to move back and forth to the left or right. Step six: As the moving component moves left and right under the force, the pressure plate at the top of the drive rod will move accordingly and will exert a downward squeezing force on the linkage rod in advance, causing it to move down along the limiting hole and directly carry the limiting block and strip bracket at its bottom down. At the same time, it will exert a squeezing force on the elastic element, causing it to deform under the force and generate corresponding elastic potential energy. Step 7: As the teeth on the outside of the strip support mesh with the gear, when the strip support moves down, the teeth on its end face will exert a downward force on the gear, causing the gear to rotate counterclockwise. At the same time, the rotation directly carries the push rod and the movable component to rotate along the inner and outer walls of the discharge nozzle, scraping the residual material on the inner wall of the discharge nozzle. Then, combined with the movable component's left and right back-and-forth movement, some of the residual material can be discharged from the discharge nozzle. The part that is not directly discharged will not directly stick to the inner wall of the discharge nozzle, so that it can be directly carried away and shaken off when sludge is applied again in the future. This ensures the cleanliness of the discharge nozzle and reduces the degree of contamination by residual material. Step 8: When the pressure plate at the top of the linkage rod is subjected to force during the movement, it will carry the pressure plate away from the top of the linkage rod. After they separate, the linkage rod can be reset under the elastic rebound force of the elastic element and directly carry the strip bracket upward, and generate an upward pushing force on the gear, so that the gear can rotate clockwise. This method can be used to scrape the residual material on the inner wall of the discharge nozzle in both directions, thereby preventing the residual material from solidifying on the inner wall of the discharge nozzle. Step 9: When it is necessary to adjust the pushing range of the drive rod, the output end of the electric push rod can be extended under the action of electricity, and the push rod can be directly pushed to move upward. Then, under the action of the push block, the moving push rod directly generates an upward pulling force on the push component, so that the push component moves upward along the slide rod in the sliding groove, thereby making the distance between the push component and the center point of one end of the drive disk increasingly farther. The farther away from the center point, the longer the trajectory and length of the right side of the drive rod during rotation, thus making the left and right movement trajectory of the drive rod longer. This allows the left and right pushing force generated on the annular pressure frame to produce a larger left and right movement range. As the movement range increases, the left and right frequency of its movement becomes less frequent. Conversely, shortening the output end of the electric push rod will directly drive the push component to move downward, making the distance between the push component and the center point shorter, thereby shortening the movement range of the drive rod. This allows for direct adjustment of the movement range of the drive rod without changing the movement frequency, and does not affect the normal operation of the entire linkage component. Furthermore, by using a pressure block, a telescopic kit, and a spring, with the pressure block located inside the arc-shaped movable hole, the pressure block can elastically press against the push block under the action of the telescopic kit and the spring. This pressure ensures that the push block remains inside the arc-shaped movable hole and can be movably connected, thus allowing it to have a certain range of motion during adjustment using the electric push rod. This prevents the adjustment from being obstructed due to a fixed connection or a direct rotational connection. At the same time, the elastic pressure prevents the push block from always moving inside the arc-shaped movable hole, avoiding the phenomenon of linkage disengagement and improving stability.
[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. By making one end of the sludge scraper ring body a double-blade structure, it forms different clearances with the sludge-beating cylinder body (larger clearance at the front end and smaller clearance at the rear end), so that the sludge-beating cylinder can classify and clean the sludge flowing into the sludge-beating cylinder from the side during the retraction process, thereby improving the efficiency and effect of sludge cleaning. It can also make good use of the structural advantages to clean the sludge-beating mechanism during operation, thereby improving the reliability of stable operation of the equipment. In addition, the parts are easy to process and have good installation and adjustment. 2. By setting a self-lubricating copper sleeve end on the sludge scraper ring, the self-lubricating copper sleeve and the sludge-removing cylinder body adopt a small clearance fit and have a certain fit length, so as to better support the sludge-removing cylinder during operation. 3. Through the mud-discharging plug and mud-scraping ring, during the retraction of the mud-discharging cylinder, the piston sleeve of the mud-discharging piston can clean the residual mud on the inner wall of the mud cylinder, and the mud-scraping ring can clean the back mud flowing into the mud-discharging cylinder. Furthermore, through its structural fit and size setting, it has a certain guiding effect on the waste gun mud, making it easy to be discharged from the mud leakage hole set on the drive cavity during the process, ensuring the reliability of the mud-discharging mechanism in mud-discharging operation. 4. Through the set active components, linkage components, push components, and drive components, the active components can move back and forth left and right and rotate forward and backward at the discharge nozzle position, so that it can better scrape the residual material inside the discharge nozzle. Some of the residual material can be discharged out of the discharge nozzle 101, and the part that is not directly discharged will not directly stick to the inner wall of the discharge nozzle. It can be carried away and shaken off when sludge is applied again in the future, thus ensuring the cleanliness of the discharge nozzle and reducing the degree of contamination of residual material. 5. By setting up drive components, adjustment components, support blocks, and pushers, the range of movement of the component can be directly adjusted without changing the activity frequency, and without affecting the normal activity of the entire linkage component.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.
[0021] Please see Figures 1 to 19 In this embodiment of the invention, a mud scraping structure of a mud scraping mechanism includes a cannon body assembly 2, a cannon nozzle assembly 1 is provided on one side of the cannon body assembly 2, and a mud cylinder 201, a mud scraping plug 3, and a drive cavity 6 are arranged sequentially from left to right inside the cannon body assembly 2. A mud scraping oil cylinder 4 is installed inside the drive cavity 6. The cannon nozzle assembly 1 includes a discharge nozzle 101, and a movable component 9 extending into the discharge nozzle 101 is provided on one side of the cannon nozzle assembly 1. A drive component 13 and a linkage component 14 are provided at one end of the cannon body assembly 2. Among them, a pressure plate 303 is provided on one side of the mud plug 3, and a mud plug sleeve 301 is provided on the other side of the pressure plate 303 and outside the output end of the mud cylinder 4. Front and rear mud plug rings 302 are provided on the outside of the mud plug sleeve 301 and near the pressure plate 303. Among them, a scraping ring 7 is provided inside the drive cavity 6 on the side near the mud plug 3, a fixing ring 8 is provided on one side of the scraping ring 7, and a self-lubricating copper sleeve 701 is provided inside the scraping ring 7.
[0022] In this embodiment, the mud scraper ring 7 consists of two parts: the mud scraper ring 7 body and the self-lubricating copper sleeve 701. The mud scraper ring 7 body and the self-lubricating copper sleeve 701 are fitted with an interference fit. The mud scraper ring 7 is fixedly connected to the drive cavity 6 by bolts.
[0023] In this embodiment, the push rod 1201 is designed to be sufficiently long. Firstly, this allows for centralized storage of the drive and linkage components, facilitating subsequent maintenance. Secondly, this linkage structure is positioned as far away from the discharge nozzle 101 as possible. The discharge nozzle 101 directly connects to the molten iron tapping point of the smelting furnace for mud removal. Even if the discharge nozzle 101 does not directly contact the discharge port, the close proximity results in a relatively high temperature. Placing the drive and linkage components directly on the discharge nozzle 101 is unsafe, and the high temperature could affect the interoperability between the components. Furthermore, since the drive utilizes a motor 1301, which generates heat, placing it directly at the discharge nozzle 101 would expose it to direct heat from the smelting furnace during mud removal, affecting the motor's performance and reducing its lifespan. Therefore, it is best to keep it as far away from direct heat sources as possible.

[0025] In this embodiment, the first elastic telescopic sleeve 1202 and the second elastic telescopic sleeve 1204 are used to provide elastic buffering for the vibration force generated during the activity.
[0026] like Figures 2 to 9 As shown, a slide rod 1307 is provided at the middle position of the top of one end of the drive disc 1302. One end of the slide rod 1307 is evenly connected to multiple sets of rolling balls 1308 (one end of the slide rod 1307 is evenly provided with multiple sets of rolling grooves that match the rolling balls 1308, so that the rolling balls 1308 can always roll inside them, thereby making the sliding between the pusher 17 and the slide rod 1307 more effortless, reducing the frictional resistance generated during sliding, and making the sliding more effortless. In addition, a brake block is provided at the top of one end of the slide rod 1307 to limit the range of motion of the pusher 17, preventing it from falling off the top of the slide rod 1307 and improving the stability of sliding). The adjustment assembly 15 includes an electric push rod 1501. A push rod 1502 is connected to the top of one end of the electric push rod 1501. A docking frame 1504 is provided at the bottom of the electric push rod 1501. Screws 1506 are rotatably connected to both sides of the bottom of the docking frame 1504 through bearings 1505. One side of one end of the push rod 1502 is rotatably connected to the output end of the electric push rod 1501 through a pin. A push block 1503 is provided on the other side of one end of the push rod 1502. In this embodiment, since there are relatively many structures pushed on the sides of the drive disc 1302 and drive rod 1304, they need to be coordinated and operated in a coordinated manner. The force is concentrated on the drive disc 1302, resulting in a relatively large force applied by the drive end of the drive disc 1302. Therefore, if a simple telescopic structure (similar to an electric telescopic rod) is used directly, although the operation can be achieved, the adjustment range is small, requiring relatively small equipment. Furthermore, due to the numerous components on its sides, the telescopic structure is prone to deformation and bending under force during the application of force, potentially leading to breakage. If the telescopic structure bends under force, it will directly damage or affect its normal operation. The present invention employs lateral force application, moving along the middle slide bar 1307, causing the drive end on the drive disc 1302 and drive rod 1304 to move along the slide bar 1307. This ensures that the force applied and received by the first rotating shaft 1303 is only applied to the slide bar 1307, with a small portion applied to the side adjustment component 15. This greatly ensures the stability of the equipment to a certain extent. Furthermore, the electric push rod 1501 applies lateral force. With the cooperation of the slide bar 1307, it only needs to generate a lateral forward thrust on the push member 17 to move the push member 17 along the slide bar 1307. This not only enables the adjustment of the position of the push member 17 but also avoids the phenomenon of bending or damage to the electric push rod 1501 due to the reaction force. A sliding groove 1702 matching the slide rod 1307 is provided at the middle position of one end of the pusher 17. Both sides of one end of the pusher 17 are provided with arc-shaped movable holes 1701 extending to the other end. A pressing block 1705 is provided inside each arc-shaped movable hole 1701. Limiting protrusions 1706 are provided at both ends of the top and bottom of the pressing block 1705 (the limiting protrusions 1706 allow the pressing block 1705 to slide more smoothly inside the arc-shaped movable hole 1701). More stable, preventing parts from falling off due to slippage, thus improving the stability of use); both sets of limiting protrusions 1706 are provided with telescopic components 1703 at the ends away from the first rotating shaft 1303, and springs 1704 are fitted on the outside of the telescopic components 1703. The other end of the telescopic components 1703 is fixedly connected to one side inside the arc-shaped movable hole 1701. The push block 1503 is located inside the arc-shaped movable hole 1701 and on the side of the push block 1503 away from the telescopic components 1703. Both sides of the top of the support block 16 are provided with threaded holes extending to its lower side. The screw rods 1506 are threadedly connected to the support block 16 through the threaded holes. The electric push rod 1501 is detachably connected to the screw rods 1506 through the nut 1507.
[0027] In this embodiment, when the bottom of the telescopic kit 1703 is connected, the two sets of screws 1506 at its bottom can be directly extended into the threaded holes inside the support block 16. During the extension along the inside of the threaded holes, the screws 1506 can rotate and move downward along the threaded trajectory on the inner wall of the threaded holes under the action of the bearing 1505. When the electric push rod 1501 moves to the appropriate position, it can be fixed with the nut 1507, thereby making the electric push rod 1501 more stable after installation. The two sets of fixed screws 1506 can restrict each other. At the same time, since the electric push rod 1501 is purchased directly, its length is limited. During the installation process, due to the fixed length, there will be a certain distance error. Here, the cooperation of the screws 1506 and the bearing 1505, combined with the fixing of the nut 1507, can make up for this gap.
[0028] like Figure 1 , 2 As shown in Figure 4, the movable component 9 includes a movable rod 901. A ring bracket 903 is provided on one side of the movable rod 901, located outside the discharge nozzle 101 and movably connected thereto. Fixed rods 904 are provided at the top and bottom of one side of the ring bracket 903. A ring pressing frame 905 is provided on one side of the fixed rod 904. Arc-shaped scrapers 902 extending into the discharge nozzle 101 are provided at the top and bottom of the ring pressing frame 905. The two sets of arc-shaped scrapers 902 are respectively attached to the inner wall of the discharge nozzle 101. The other side of the movable rod 901 is fixedly connected to the end of the first elastic telescopic sleeve 1202 away from the push rod 1201.
[0029] In this embodiment, the thickness of the right end of the two sets of arc scrapers 902 on adjacent sides decreases from left to right and decreases toward the inner wall of the discharge nozzle 101, so that the material squeezed out from its right side can be better pushed out of the discharge nozzle 101 along the inclined surface and will not be affected by the resistance of the arc scraper 902, making its discharge smoother.
[0030] like Figure 2 and 3 As shown, a sliding groove matching the sliding block 1205 is provided at the bottom of one end of the drive cavity 6. The fixed frame 1203 is slidably connected to the outside of the drive cavity 6 through the mutual cooperation of the sliding block 1205 and the sliding groove. An outer protective shell 11 is sleeved on the bottom of the outer side of the drive cavity 6. An movable hole 10 is provided on the side of the outer protective shell 11 near the discharge nozzle 101. The push rod 1201 is movably connected to the outer protective shell 11 through the movable hole 10. In this embodiment, the sliding block 1205 and the sliding groove are used to limit the range of motion of the fixed frame 1203, so that it can only slide left and right along this position, thereby improving the aligning and turning effect of the drive rod 1304.
[0031] like Figure 2 and 3 As shown, a limiting hole 1402 extending downwards is provided at one end of the top of the limiting frame 1401. The linkage rod 1403 is located inside the limiting hole 1402 and is movably connected to the limiting frame 1401 through the limiting hole 1402, so that the linkage rod 1403 can move up and down more smoothly in this position, thereby improving the stability of use. The length of the gear 1206 is long enough so that the locking tooth 1407 is always in a meshing state with the gear 1206. At the same time, the limiting frame 1401 is fixedly connected to the drive cavity 6 by bolts.
[0032] like Figure 11 , 12 As shown in 13, 14 and 19, one end of the mud plug sleeve 301 is used to install the front and rear mud plug rings 302. The front and rear mud plug rings 302 are expansion ring structures. One end of the mud plug sleeve 301 is provided with a blade structure with a certain thickness and inclination angle. There is an movable gap between the tip of the blade of the mud plug sleeve 301 and the inner hole of the mud cylinder 201. The mud plug 3 is connected to the output end of the mud pumping cylinder 4 by bolts. The other side of the gun body assembly 2 is provided with a stroke indicator 5.
[0033] In this embodiment, the cutting edge of the mud plug sleeve 301 has an appropriate clearance fit with the inner hole of the mud cylinder 201, which facilitates the mud removal cylinder 4 to clean the back mud on the drive cavity 6 side when it is retracting, and allows it to smoothly leak out from the mud leakage hole provided on the drive cavity 6. The stroke indicator 5 is a key information that clearly indicates the trajectory or position of an object through a specific device or mark. It is mainly used to guide or limit the operating range of the equipment. The stroke indicator of the mud removal cylinder 4 is used to display the stroke position of the mud removal cylinder 4. The device provides real-time feedback on the operating status to ensure that the equipment operates within a safe range.
[0034] like Figure 11 , 12 As shown in 15, 16 and 19, the mud scraper ring 7 is made of steel, and one end of the mud scraper ring 7 has a double-blade structure. Different gaps are formed between the mud scraper ring 7 and the mud-removing cylinder 4. The mud scraper ring 7 and the self-lubricating copper sleeve 701 are interference fit. The mud scraper ring 7 is fixedly connected to the drive cavity 6 by bolts.
[0035] In this embodiment, the scraper ring 7 can be made of steel / iron. One end has a double-bladed structure, which forms different clearances with the cylinder body of the sludge-removing cylinder 4 (larger clearance at the front end and smaller clearance at the rear end). This allows the sludge-removing cylinder 4 to perform graded cleaning of the sludge flowing into the sludge cylinder 4 from the side of the sludge cylinder 201 during the retraction process, thereby improving the efficiency and effect of sludge removal. The other end is equipped with a self-lubricating copper sleeve 701. The self-lubricating copper sleeve 701 has a small clearance and a certain length with the cylinder body of the sludge-removing cylinder 4, so as to better support the sludge-removing cylinder 4 during operation. When the self-lubricating copper sleeve 701 is worn to a certain extent, it can be replaced.
[0036] like Figure 11 , 12 As shown in 15, 16, 17, 18 and 19, the mud scraper ring 7 is axially and radially clamped onto the inner wall of the gun body assembly 2 by the fixing ring 8, and an inclined surface is provided between the inner hole of the fixing ring 8 and the mud scraper ring 7, and the included angle of inclination of the inclined surface is greater than 90°.
[0037] In this embodiment, the steel plate end of the fixing ring 8 has a certain thickness and the inner hole has a certain angle. After being fully assembled with the mud scraper ring 7, the inclined surfaces between the two form an angle of not less than 90°. This structure facilitates the smooth introduction of the blasting mud cleaned by the mud scraper ring 7 during the forward movement into the mud leakage hole, which is convenient for the discharge of waste mud.
[0038] like Figure 11 , 12 As shown in Figures 15, 16, 18, and 19, the mud scraper ring 7 is located outside the mud-removing cylinder 4 and is movably connected to the mud-removing cylinder 4. The mud scraper ring 7 is axially locked and positioned by the fixed ring 8, and the mud scraper ring 7 is radially engaged with the drive cavity 6 to achieve positioning connection.
[0039] Working principle: The mud-scraping mechanism's mud-cleaning method specifically includes the following steps: Step 1: When the mud-discharging cylinder 4 moves forward, it drives the mud-discharging plug 3 assembly to move forward, thereby squeezing the gunning mud in the mud cylinder 201 into the iron taphole channel. Step 2: During operation, some of the gunning mud will enter the side of the gunning cylinder 4 through the gap between the gunning mud plug 3 and the steel. At the same time, some gunning mud may also be attached to the inner wall of the mud cylinder 201. When the gunning cylinder 4 retracts, this returned mud will obstruct the retracted gunning mud plug 3 and the gunning cylinder 4, forming resistance. Step 3: The new structure of the mud-dissolving plug 3 and the mud-scraping ring 7 is adopted. The self-lubricating copper sleeve 701 in the mud-scraping ring 7 plays a good supporting role in the operation of the mud-dissolving cylinder 4. Step four: During the retraction of the mud-removing cylinder 4, the mud plug sleeve 301 of the mud-removing plug 3 cleans the residual mud on the inner wall of the mud cylinder 201, and the mud scraper ring 7 cleans the back mud flowing into the mud-removing cylinder 4. Through its structural fit and size setting, it has a certain guiding effect on the waste gun mud, so that it can be discharged from the mud leakage hole set on the drive cavity 6 during the process, ensuring the reliability of the mud-removing mechanism in mud-removing operation. Step 5: After the mud material exits from the discharge nozzle 101, some residual material will remain on the discharge nozzle 101. When processing the residual material, the motor 1301 rotates clockwise under the action of electricity, and directly drives the drive disk 1302 to rotate. While rotating, the drive disk 1302 carries the first rotating shaft 1303 around the center point of the drive disk 1302 as the base point, and directly acts on the drive rod 1304. At the same time, since the other end of the drive rod 1304 is directly rotatably connected to the fixed frame 1203, the drive rod 1304 can rotate around the first rotating shaft 1303 and the second rotating shaft 1305 as the base point along the movement trajectory of the first rotating shaft 1303. Since the length of the drive rod 1304 remains unchanged, in order to ensure the conservation of force, the fixed frame 1203 and the drive rod 1201 can be directly pushed to move back and forth to the left or right. Step six: As the moving component 9 moves left and right under the force, the pressure plate 1306 at the top of the drive rod 1304 will move accordingly, and will pre-exert a downward squeezing force on the linkage rod 1403, causing it to move down along the limiting hole 1402, and directly carry the limiting block 1405 and the strip bracket 1406 at its bottom down, while simultaneously exerting a squeezing force on the elastic element 1404, causing it to deform under the force and generate corresponding elastic potential energy; Step 7: Since the teeth 1407 on the outside of the strip bracket 1406 are engaged with the gear 1206, as the strip bracket 1406 moves downward, the teeth 1407 on its end face will exert a downward pushing force on the gear 1206, causing the gear 1206 to rotate counterclockwise. At the same time, the rotation directly carries the push rod 1201 and the movable component 9 to rotate along the inner and outer walls of the discharge nozzle 101, and scrapes the residual material on the inner wall of the discharge nozzle 101. Then, in conjunction with the movable component 9, it makes a left and right back and forth movement, which can discharge some of the residual material from the discharge nozzle 101. The part that is not discharged directly will not directly stick to the inner wall of the discharge nozzle 101, so that it can be carried away and shaken off when mud is sludged again in the future. This ensures the cleanliness of the discharge nozzle 101 and reduces the degree of contamination of residual material. Step 8: When the pressure plate 1306 at the top of the linkage rod 1403 is subjected to force during the movement, it will carry the pressure plate 1306 away from the top of the linkage rod 1403. After they are separated, the linkage rod 1403 can be reset under the elastic rebound force of the elastic element 1404 and directly carry the strip bracket 1406 upward, and generate an upward pushing force on the gear 1206, so that the gear 1206 can rotate clockwise. This method can be used to scrape the residual material on the inner wall of the discharge nozzle 101 in both directions, thereby preventing the residual material from solidifying on the inner wall of the discharge nozzle 101. Step nine: When it is necessary to adjust the pushing range of the drive rod 1304, the output end of the electric push rod 1501 can be extended under the action of electricity, and directly push the push rod 1502 to move upward. Then, under the action of the push block 1503, the moving push rod 1502 directly generates an upward pulling force on the push member 17, thereby causing the push member 17 to move upward along the slide rod 1307 in the sliding groove 1702. This makes the distance between the push member 17 and the center point of one end of the drive disk 1302 increasingly farther. The farther away from the center point, the longer the trajectory and length of the right side of the drive rod 1304 during rotation. The longer the length, the longer the left and right movement trajectory of the drive rod 1304, which in turn allows it to exert a greater left and right pushing force on the annular pressing frame 905, resulting in a larger left and right movement range. As the movement range increases, the left and right frequency of its movement decreases. Conversely, the shortening of the output end of the electric push rod 1501 will directly drive the pusher 17 to move downward, making the distance between the pusher 17 and the center point shorter. This will shorten the movement range of the drive rod 1304, allowing direct adjustment of its movement range without changing the activity frequency, and without affecting the normal operation of the entire linkage assembly 14. Furthermore, through the setting of the pressing block 1705, the telescopic kit 1703, and the spring 1704, the pressing block 1705 is located inside the arc-shaped movable hole 1701. Under the action of the telescopic kit 1703 and the spring 1704, the pressing block 1705 can elastically press the pushing block 1503. This pressing method ensures that the pushing block 1503 is always located inside the arc-shaped movable hole 1701 and can be movably connected. This allows it to have a certain range of motion during the adjustment process using the electric push rod 1501, preventing the adjustment from being obstructed due to a fixed connection or direct rotational connection. At the same time, the elastic pressing method prevents the pushing block 1503 from always moving inside the arc-shaped movable hole 1701, avoiding the phenomenon of linkage disengagement and improving stability.

10. A method for cleaning mud using a mud scraping structure of a mud-beating mechanism, characterized in that, The sludge removal method of the sludge scraping structure of the sludge removal mechanism specifically includes the following steps: Step 1: When the mud-discharging cylinder moves forward, it drives the mud-discharging plug assembly forward, thereby squeezing the mud in the mud cylinder into the taphole channel. Step 2: During operation, some of the gunning mud will enter the side of the gunning cylinder through the gap between the gunning plug and the steel. At the same time, some gunning mud may also adhere to the inner wall of the cylinder. When the gunning cylinder retracts, this returned mud will obstruct the retracted gunning plug and the gunning cylinder, forming resistance. Step 3: A new type of mud-dissolving plug and scraper ring are adopted. The self-lubricating copper sleeve in the scraper ring provides good support for the operation of the mud-dissolving cylinder. Step four: During the retraction of the mud-removing cylinder, the piston sleeve of the mud-removing piston cleans the residual mud on the inner wall of the mud cylinder, and the mud scraper ring cleans the returned mud flowing into the mud-removing cylinder. Through its structural fit and size setting, it has a certain guiding effect on the waste gun mud, so that it can be discharged from the mud leakage hole set on the drive cavity during the process, ensuring the reliability of the mud-removing mechanism in mud-removing operation. Step 5: After the mud material exits from the discharge nozzle, some residual material will remain on the discharge nozzle. When processing the residual material, the motor rotates clockwise under the action of electricity, directly driving the drive disc to rotate. As the drive disc rotates, it carries the first rotating shaft around the center point of the drive disc and directly acts on the drive rod. At the same time, since the other end of the drive rod is directly rotatably connected to the fixed frame, the drive rod can rotate around the first rotating shaft and the second rotating shaft as the base point along the movement trajectory of the first rotating shaft. Since the length of the drive rod remains unchanged, in order to ensure the conservation of force, it can directly push the fixed frame and the push rod to move back and forth to the left or right. Step six: As the moving component moves left and right under the force, the pressure plate at the top of the drive rod will move accordingly, and will pre-exert a downward squeezing force on the linkage rod, causing it to move down along the limiting hole, and directly carrying the limiting block and strip bracket at its bottom down, while simultaneously squeezing the elastic element, causing it to deform under the force and generate corresponding elastic potential energy. Step 7: As the teeth on the outside of the strip support mesh with the gear, when the strip support moves down, the teeth on its end face will exert a downward force on the gear, causing the gear to rotate counterclockwise. At the same time, the rotation directly carries the push rod and the movable component to rotate along the inner and outer walls of the discharge nozzle, scraping the residual material on the inner wall of the discharge nozzle. Then, combined with the movable component's left and right back-and-forth movement, some of the residual material can be discharged from the discharge nozzle. The part that is not directly discharged will not directly stick to the inner wall of the discharge nozzle, so that it can be directly carried away and shaken off when sludge is applied again in the future. This ensures the cleanliness of the discharge nozzle and reduces the degree of contamination by residual material. Step 8: When the pressure plate at the top of the linkage rod is subjected to force during the movement, it will carry the pressure plate away from the top of the linkage rod. After they separate, the linkage rod can be reset under the elastic rebound force of the elastic element and directly carry the strip bracket upward, and generate an upward pushing force on the gear, so that the gear can rotate clockwise. This method can be used to scrape the residual material on the inner wall of the discharge nozzle in both directions, thereby preventing the residual material from solidifying on the inner wall of the discharge nozzle. Step 9: When it is necessary to adjust the pushing range of the drive rod, the output end of the electric push rod can be extended under the action of electricity, and the push rod can be directly pushed to move upward. Then, under the action of the push block, the moving push rod directly generates an upward pulling force on the push component, so that the push component moves upward along the slide rod in the sliding groove, thereby making the distance between the push component and the center point of one end of the drive disk increasingly farther. The farther away from the center point, the longer the trajectory and length of the right side of the drive rod during rotation, thus making the left and right movement trajectory of the drive rod longer. This allows the left and right pushing force generated on the annular pressure frame to produce a larger left and right movement range. As the movement range increases, the left and right frequency of its movement becomes less frequent. Conversely, shortening the output end of the electric push rod will directly drive the push component to move downward, making the distance between the push component and the center point shorter, thereby shortening the movement range of the drive rod. This allows for direct adjustment of the movement range of the drive rod without changing the movement frequency, and also affects the normal operation of the entire linkage component. Furthermore, by using a pressure block, a telescopic kit, and a spring, with the pressure block located inside the arc-shaped movable hole, the pressure block can elastically press against the push block under the action of the telescopic kit and the spring. This pressure ensures that the push block remains inside the arc-shaped movable hole and can be movably connected, thus allowing it to have a certain range of motion during adjustment using the electric push rod. This prevents the adjustment from being obstructed due to fixed connections or direct rotational connections. At the same time, the elastic pressure prevents the push block from always moving inside the arc-shaped movable hole, avoiding the phenomenon of linkage disengagement and improving stability.
