Description

Technical Field

[0001] This invention belongs to the technical field of material conveying equipment, specifically a T-shaped scraper structure. Background Technology

[0002] In the field of material conveying, especially during the operation of conveyors handling powdery, granular, or sticky materials, material spillage is a common problem. To address this issue, the industry typically equips conveyors with scraper conveyors below the main conveyor. The spilled material is collected on the bottom surface of the inner wall of the frame of this device, and then two sets of circulating chains drive multiple sets of T-shaped scrapers to move synchronously. Through the close contact between the vertical plates of the T-shaped scrapers and the bottom surface of the inner wall of the frame, the material is continuously scraped and conveyed for discharge, thus completing the recovery and centralized processing of the material.

[0003] In existing technologies, T-type scrapers have significant drawbacks during long-term use: their vertical plates remain in constant contact with the bottom surface of the inner wall of the frame. During continuous scraping of materials, the contact area of ​​the vertical plates gradually wears down due to friction and material impact (especially the lower and middle areas that are in high-frequency contact with the materials). As wear intensifies, gaps inevitably form between the vertical plates and the bottom surface of the inner wall of the frame, causing some materials to leak through and not be effectively scraped away. This leakage problem not only reduces material recovery efficiency but also leads to abnormal wear of the T-type scraper, affecting the stable operation of the entire conveying equipment. Although some T-type scrapers can be replaced when they wear out, the entire scraper is replaced at once, which not only wastes some intact parts of the scraper but also increases operating costs. Therefore, we propose a T-type scraper structure. Summary of the Invention

[0004] The purpose of this invention is to provide a T-shaped scraper structure to solve the technical problems mentioned in the background art.

[0007] Preferably, two sets of upper spiral plates are also fixedly installed on one side of the vertical plate; Multiple upper plates are fixedly installed on the top of the long scraper.

[0008] Preferably, an extension plate is fixedly provided at both ends of the box body, two sets of mounting springs are fixedly provided between the extension plate and the horizontal plate, and a telescopic square tube is also fixedly provided between the extension plate and the horizontal plate.

[0009] Preferably, a telescopic component is provided on one side of the long scraper. The telescopic component includes a lower circular plate fixed to one side of the long scraper and a movable strip slidably disposed inside the lower circular plate. A movable scraper is fixedly disposed at the end of the movable strip for adjusting the frame of different widths.

[0010] Preferably, the lower spiral plate has a locking stud connected to its interior by a thread, and the end of the locking stud is fitted with a rubber sleeve for protection.

[0011] Preferably, the top of the frame is fixedly provided with multiple sets of reinforcing frames, and a cleaning component is provided on one side of the reinforcing frame. The cleaning component includes a mounting plate and a hollow convex plate fixed to one side of the reinforcing frame. Multiple sets of nozzles are evenly provided on one side of the hollow convex plate and along the length of the hollow convex plate for blowing and cleaning the material adhering to the surface of the vertical plate, auxiliary scraper and long scraper.

[0012] Preferably, two sets of connecting frames are fixedly provided at the bottom of the mounting plate, and a rotating rod is rotatably provided inside the connecting frame for adjusting the blowing angle of the nozzle; A waterproof motor is fixedly installed on the connecting frame, and the working end of the waterproof motor is fixedly connected to the end of the rotating rod. A connecting pipe is fixedly installed on the other side of the hollow convex plate. Two sets of hydraulic rods are fixedly installed on the hollow convex plate. A connecting frame is fixedly installed at the top working end of the hydraulic rod, and a baffle is fixedly installed at the end of the connecting frame. A rubber plate is fixedly installed on the side of the baffle to protect the mouthpiece.

[0013] Preferably, both ends of the vertical plate are provided with a bullnose bracket, and the bullnose bracket is provided with two sets of mounting bolts. The working end of the mounting bolt passes through the bullnose bracket and the interior of the vertical plate, and the working end of the mounting bolt is connected to a nut by a thread.

[0014] Preferably, two sets of rotating shafts are rotatably mounted on the frame, and sprockets are fixedly fitted at both ends of the rotating shafts. A reduction motor is fixedly mounted on the frame, and two sets of chain pressure plates are fixedly mounted on the inner wall of the frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention uses an auxiliary scraping mechanism. When the vertical plate is worn and a gap is generated between it and the bottom of the inner wall of the frame, the auxiliary scraper is attached to the inner wall of the frame under the action of the upper spring, and the long scraper fills the gap at both ends of the vertical plate. The two work together to prevent material from leaking through, ensure material recycling efficiency, reduce abnormal wear of equipment caused by material leakage, and eliminate the need to replace the T-shaped scraper when the vertical plate is slightly worn.

[0016] (2) The present invention uses a telescopic component to push the moving strip to slide in the lower circular plate, which can adjust the extension length of the moving scraper so that it can fit tightly against the side wall of the frame with different widths, adapt to various specifications of conveying equipment, and improve the versatility of the device. In response to the problem of gap between the long scraper and the side wall of the frame that is prone to occur in frames with different widths, the moving scraper can accurately seal the gap to prevent material from leaking out from the side wall. At the same time, the end of the long scraper near the auxiliary scraper extends to the overlapping area, further eliminating the gap between the long scraper and the auxiliary scraper, ensuring the integrity of material recycling. The telescopic component works in conjunction with the auxiliary scraper and the long scraper of the auxiliary scraping mechanism to solve the problem of material leakage at the bottom of the vertical plate and eliminate the hidden danger of material leakage from the side wall, forming an all-round anti-leakage scraping system.

[0017] (3) The present invention uses a cleaning component designed to spray compressed air through a nozzle on a hollow convex plate to sweep away the material adhering to the surface of the vertical plate, auxiliary scraper, and long scraper, thereby avoiding the aggravation of component friction wear after the material hardens and agglomerates, extending the service life of each scraping component, and timely removing the adhering material. This ensures that the T-shaped scraper and auxiliary scraping mechanism always operate efficiently, maintains stable material recovery efficiency, and allows adjustment of the sweeping angle of the hollow convex plate and the nozzle, so that the airflow can accurately act on the area with severe material adhesion, solving the problem of blind spots in fixed-angle sweeping and improving the cleaning effect. When the equipment is stopped, the baffle and rubber plate cover the nozzle to prevent dust from entering the nozzle and clogging the channel. Attached Figure Description

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1-11 and Figure 15This invention provides a technical solution: a T-shaped scraper structure. The T-shaped scraper adopts a T-shaped arm structure, which has high overall rigidity, making the force-bearing surface in contact with the material less prone to deformation. The T-shaped scraper has a T-shaped cross-section structure (the T-shaped scraper is coated with a wear-resistant coating to increase its wear resistance and extend its service life; the wear-resistant coating is a nano-coating). It consists of vertical plates 105 (bearing surface) and horizontal plates 106 (supporting surface). [Multiple vertical plates 105 are arranged between two chains 104. The multiple vertical plates 105 are divided into type A and type B structures. Type A consists of multiple toothless vertical plates 105 (this auxiliary scraping mechanism is only used for type A toothless vertical plates 105), and type B consists of two toothed vertical plates (based on the attached...] Figure 15 Furthermore, the teeth of the two toothed vertical plates 105 are misaligned, forming staggered teeth. During use, if material clumps, one end of the toothed vertical plate 105 can scrape the material soft, while the other end of the non-toothed vertical plate 105 scrapes away the softened material. The vertical plate 105 and the horizontal plate 106 are connected by an arc transition to avoid stress concentration. The vertical plate 105, as the main load-bearing surface, directly contacts the material and bears the friction and pressure during the operation of the scraper conveyor. The horizontal plate 106 provides lateral support, enhancing structural stability and preventing scraper deformation or twisting. Vertical plate 105 height: 50mm, tolerance ±1mm; horizontal plate 106 width: 50mm, tolerance ±1mm; arc transition. Radius: R10-R50mm, smooth surface without burrs, including a frame 100, a chain 104 rotatably mounted on the frame 100, and multiple sets of T-shaped scrapers mounted on the chain 104. The chain 104 rotates clockwise, thereby driving the T-shaped scrapers to scrape the material falling to the bottom of the inner wall of the frame 100 for discharge. When the chain 104 moves cyclically, it will drive the T-shaped scrapers to move synchronously. The vertical plate 105 contacts the bottom of the inner wall of the frame 100 to scrape off the material at the bottom of the inner wall of the frame 100. The T-shaped scraper includes a vertical plate 105 and a horizontal plate 106 fixed on the vertical plate 105. An auxiliary scraping mechanism is provided on the T-shaped scraper, which includes: A box body 200 is installed on one side of the vertical plate 105 and an auxiliary scraper 201 is slidably disposed inside the box body 200. The auxiliary scraper 201 can slide up and down along the box body 200. Two sets of long scraper strips 212 are also provided on one side of the vertical plate 105. The long scraper strips 212 are located at both ends of the vertical plate 105. The auxiliary scraper 201 and the long scraper strips 212 are used to assist in scraping away the material that leaks out at the gap between the vertical plate 105 and the bottom of the inner wall of the frame 100. Two sets of elongated boxes 202 are fixedly installed on the top of the box body 200. An upper spring 204 is fixedly installed on the top of the inner wall of each elongated box 202. Two sets of fixing plates 205 are fixedly installed on the top of the auxiliary scraper 201. The fixing plates 205 and the auxiliary scraper 201 are fixedly connected by angled screws. These angled screws allow the auxiliary scraper 201 to be replaced individually when it becomes severely worn and unusable, saving costs (when the angled screws are tilted, the working end is tilted and screwed into the interior of the auxiliary scraper 201). The top of the fixing plate 205 is fixedly connected to the bottom of the upper spring 204, and the top of the fixing plate 205 extends to the elongated box 202. Inside box 202, when the vertical plate 105 wears down due to long-term use and a gap is formed between it and the bottom of the inner wall of the frame 100, the upper spring 204 will apply a downward elastic force to the fixed plate 205, causing the auxiliary scraper 201 to slide down along the box body 200, so that the auxiliary scraper 201 fits tightly against the bottom of the inner wall of the frame 100 and fills the gap in the middle of the vertical plate 105; at the same time, the long scraper 212 fits against the bottom of the inner wall of the frame 100 and fills the gap at both ends of the vertical plate 105, together assisting in scraping away the material that is missed in the gap, and the long scraper 212 at both ends will not be affected by the bullnose frame 107 and the chain 104; It effectively solves the problem of material leakage after the vertical plate 105 wears out, eliminating the need to replace the entire T-shaped scraper when the vertical plate 105 is only slightly worn. This reduces the waste of intact parts in the T-shaped scraper (such as the horizontal plate 106) and lowers the operating cost. At the same time, it ensures material recovery efficiency, avoids abnormal wear of the T-shaped scraper caused by material leakage, and maintains the stable operation of the entire conveying equipment.

[0021] Example 2 Please refer to Example 1. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 15 Left bars 209 are slidably installed inside both ends of the box body 200, and right bars 211 are fixedly installed on the top of the long scraper 212. The right bars 211 are positioned close to the box body 200 and not in the center of the bullnose frame 107. This ensures that when the bullnose frame 107 moves synchronously with the chain 104 to the sprocket 102, the right bars 211 will not collide with or interfere with the sprocket 102 (that is, the right bars 211 avoid the sprocket 102), thus ensuring normal use. A horizontal plate 207 is fixedly installed between the left bars 209 and the right bars 211, and the bottom of the left bars 209 is fixedly connected to the long scraper 212. The left bars 209 will slide up and down inside the box body 200, and the right bars 211 will slide up and down inside the upper circular plate 208. Two sets of upper spiral plates 208 are also fixedly installed on one side of the vertical plate 105, and the long scraper 212 is slidably installed inside the upper spiral plate 208. The top of the long scraper 212 is fixedly provided with multiple upper plates, and the upper plates are fixedly connected to the right strip 211 and the left strip 209 by fixing bolts. The fixing bolts can realize the detachable connection between the long scraper 212 and the right strip 211 and the left strip 209. When the long scraper 212 is worn out and can no longer be used, the fixing bolts can be unscrewed to replace the long scraper 212 separately. Effect: Further constrains the movement direction of the long scraper 212, ensuring that it always fits against the bottom of the inner wall of the frame 100, while realizing the individual disassembly and assembly of the long scraper 212, reducing maintenance difficulty and cost, and avoiding the need to replace the entire auxiliary scraping mechanism due to local wear. Extension plates 210 are fixedly installed at both ends of the box body 200. Two sets of mounting springs 213 are fixedly installed between the extension plates 210 and the horizontal plate 207. Telescopic square tubes 206 are also fixedly installed between the extension plates 210 and the horizontal plate 207. The telescopic square tubes 206 can protect the mounting springs 213 and prevent materials from entering the mounting springs 213 and affecting their normal use. The mounting springs 213 are located inside the telescopic square tubes 206. When the long scraper 212 encounters a slight protrusion or foreign object during scraping, it will be subjected to an upward force. This force is transmitted to the mounting springs 213 through the horizontal plate 207, causing the mounting springs 213 to compress. At the same time, the telescopic square tubes 206 retract. When the foreign object disappears, the mounting springs 213 return to their original shape, pushing the horizontal plate 207 and the long scraper 212 back to their original positions and re-attaching to the bottom of the inner wall of the frame 100. This can provide buffer protection for the long scraper 212 and prevent the long scraper 212 from being deformed or damaged due to slight obstruction. Inside one side of the box 200, a main screw 500 and a secondary screw 501 are connected by threads. The working end of the main screw 500 extends to the surface of the auxiliary scraper 201, and the working end of the secondary screw 501 extends to the surface of the left strip 209. The main screw 500 can fix the auxiliary scraper 201 when no auxiliary scraping is being performed, and the secondary screw 501 can fix the left strip 209 when no auxiliary scraping is being performed, thereby fixing the long scraper 212. This makes it convenient to release the lock on the auxiliary scraper 201 and the long scraper 212 only during the auxiliary scraping process. The material at the bottom of the inner wall of the frame 100 is scraped off only when auxiliary scraping is being performed.

[0022] Example 3 Please refer to Example 2. Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 10A telescopic component is provided on one side of the long scraper 212. The telescopic component includes a lower circular plate 301 fixed to one side of the long scraper 212 and a movable strip 303 slidably disposed inside the lower circular plate 301. A movable scraper 300 is fixedly disposed at the end of the movable strip 303 for adjusting the frame 100 of different widths. When facing a frame 100 of different widths, the movable strip 303 can be pushed to slide inside the lower circular plate 301 to adjust the length of the movable strip 303 extending out of the lower circular plate 301, thereby driving the movable scraper 300 to move closer to the frame 100. The scraper 300 moves close to or away from the side wall of the frame 100 until it fits tightly against the side wall of the frame 100, thus sealing the gap between the side wall of the frame 100 and the long scraper 212. At the same time, the length of the end of the long scraper 212 near the auxiliary scraper 201 extends to the area that overlaps with the auxiliary scraper 201. The overlapping area can make the long scraper 212 and the auxiliary scraper 201 adapt to the length of different frames 100 when adjusted according to different widths of the frame 100, and can also cause material leakage at the gap between the long scraper 212 and the auxiliary scraper 201. The lower retaining plate 301 is internally connected to a locking stud 304 via threads. When adjusting the position of the movable scraper 300 according to the width of different frames 100, the locking stud 304 can be loosened to release the movable strip 303 from its fixation. Then the movable strip 303 can be moved, thereby causing the movable scraper 300 to move accordingly, changing the position of the movable scraper 300. The end of the movable scraper 300 can contact the inner wall of the frame 100 of different widths, and the working end of the locking stud 304 extends to the surface of the movable strip 303. The end of the locking stud 304 is fitted with a rubber sleeve 302 for protection. The rubber sleeve 302 isolates the end of the locking stud 304 from the external environment, preventing material dust from entering the thread gap of the locking stud 304 and preventing the end of the locking stud 304 from rusting.

[0023] Example 4 Please refer to Example 3. Figures 1-8 , Figures 10-15 The top of the frame 100 is fixedly equipped with multiple sets of reinforcing frames 103. A cleaning component is provided on one side of the reinforcing frame 103. The cleaning component includes a mounting plate 400 and a hollow convex plate 403 fixed on one side of the reinforcing frame 103. Multiple sets of nozzles 409 are evenly arranged on one side of the hollow convex plate 403 and along the length of the hollow convex plate 403. These are used to blow away and clean the material adhering to the surface of the vertical plate 105, the auxiliary scraper 201, and the long scraper 212. In use, the external air supply equipment is connected to the pipe 402 on the hollow convex plate 403 through a pipe. After the compressed air enters the interior of the hollow convex plate 403, it is evenly sprayed out through the multiple sets of nozzles 409. The airflow acts on the surface of the vertical plate 105, the auxiliary scraper 201, and the long scraper 212, blowing away and cleaning the material dust adhering to the surface of these components. It can promptly remove materials adhering to the surface of components, preventing materials from hardening and aggravating component wear. At the same time, it prevents adhering materials from affecting the scraping effect of the scraper, maintaining the long-term efficient operation of the T-type scraper structure and reducing equipment failures caused by material adhering. Two sets of connecting frames 404 are fixedly installed at the bottom of the mounting plate 400. A rotating rod 406 is rotatably installed inside the connecting frame 404 for adjusting the blowing angle of the nozzle 409. The rotating rod 406 is fixed to the top of the hollow convex plate 403. A waterproof motor 401 is fixedly installed on the connecting frame 404, and the working end of the waterproof motor 401 is fixedly connected to the end of the rotating rod 406. A connecting pipe 402 is fixedly installed on the other side of the hollow convex plate 403. When the waterproof motor 401 is started, its output shaft drives the rotating rod 406 to rotate inside the connecting frame 404. The rotating rod 406 drives the hollow convex plate 403 to rotate synchronously, thereby adjusting the blowing angle of the nozzle 409 so that the airflow can accurately act on the area with severe material adhesion. Two sets of hydraulic rods 407 are fixedly installed on the hollow convex plate 403. A connecting frame is fixedly installed at the top working end of the hydraulic rod 407, and a baffle 405 is fixedly installed at the end of the connecting frame. A rubber plate 408 is fixedly installed on the side of the baffle 405 to protect the nozzle 409. When the equipment stops cleaning, the working end of the hydraulic rod 407 extends, driving the connecting frame and the baffle 405 to move towards the nozzle 409 until the rubber plate 408 completely covers the nozzle 409 to prevent material dust from entering the nozzle 409 and causing blockage. Effects: Enables flexible adjustment of the blowing angle of the nozzle 409, improving cleaning targeting and efficiency; the waterproof motor 401 can adapt to humid or dusty environments, ensuring stable adjustment function; the baffle 405 and rubber plate 408 can effectively protect the nozzle 409, preventing it from clogging and failing, extending the service life of the cleaning components, and reducing maintenance frequency.

[0024] In this embodiment, both ends of the vertical plate 105 are provided with bullnose brackets 107. The joint ends of the bullnose brackets 107 are arc-shaped protrusions (similar to "bull noses"), which have a large contact area and high wear resistance when meshing with the sprocket 102. Two sets of mounting bolts are provided on the bullnose brackets 107. The working ends of the mounting bolts pass through the interior of the bullnose brackets 107 and the vertical plate 105 [that is, multiple mounting holes are opened inside both ends of the vertical plate 105, and the working ends of the mounting bolts can pass through the mounting holes, and the vertical plate 105 is fixed by the mounting bolts through the mounting holes (i.e., the T-shaped scraper). [To prevent the T-shaped scraper from shifting during use], the working end of the mounting bolt is connected to a nut via a thread. The bullnose bracket 107 is connected in series with the chain 104. The bullnose bracket 107 has a modular design for the joint, which can be quickly replaced after wear, reducing maintenance costs. The joint holes are machined by a CNC boring machine to ensure the hole diameter, hole spacing, and perpendicularity. The bullnose arc surface is formed by mold pressing, with a surface roughness Ra≤3.2μm, hole center distance: 20-40mm, tolerance ±0.1mm; bullnose arc: R10-R50mm, surface hardness ≥HRC45. Tightening the nut secures the bullnose frame 107 to the vertical plate 105. The bullnose frame 107 is connected to the chain 104. When the chain 104 moves in a cycle, it drives the bullnose frame 107 to move synchronously. In turn, the bullnose frame 107 drives the T-shaped scraper composed of the vertical plate 105 and the horizontal plate 106 to move, thereby scraping off the material. The T-shaped scraper is made of wear-resistant steel NM500 or other wear-resistant materials; the height of the entire scraper can be adjusted according to the different characteristics of the conveyed material to improve the scraping efficiency; according to the specific gravity and adhesiveness of the material, the T-shaped arm structure can be changed to an H-shaped arm structure to improve the overall rigidity and scraping effect. The NM500 steel plate is precisely cut using a CNC laser cutting machine to ensure that the dimensions of the T-shaped structure meet the design requirements; The T-arm is welded to the vertical plate 105 and the horizontal plate 106 using fully automatic welding. The weld grade is not lower than Grade II, and the weld is ground smooth after welding. In this embodiment, two sets of rotating shafts 101 are rotatably mounted on the frame 100. Sprockets 102 are fixedly fitted at both ends of the rotating shafts 101. Chains 104 are fitted around the outside of the sprockets 102. A geared motor is fixedly mounted on the frame 100. The geared motor drives one end of the rotating shaft 101 to rotate, thereby driving the chain 104 to rotate. Two sets of chain pressure plates 108 are fixedly mounted on the inner wall of the frame 100. The chain pressure plates 108 are located between the chains 104 to limit the movement of the chains 104 and prevent the chains 104 from jumping upwards due to vibration or load during movement.

[0025] Working principle and usage process of this invention: When this invention is in use, if a gap is created between the vertical plate 105 and the bottom of the inner wall of the frame 100 due to wear, the main screw 500 is loosened by rotating it to release the fixation of the auxiliary scraper 201. Then, the secondary screw 501 is loosened by rotating it to release the fixation of the left strip 209. At this time, the auxiliary scraper 201 inside the box 200 on one side of the vertical plate 105 moves towards the bottom of the inner wall of the frame 100 under the elastic pressure of the spring 204 on the top of the inner wall of the box 200. Then, the surface of the auxiliary scraper 201 contacts and always adheres to the bottom of the inner wall of the frame 100, filling the gap in the middle of the vertical plate 105; at the same time, the long scraper strips 212 at both ends of the vertical plate 105... Under the squeezing action of the spring 213, the scraper moves towards the bottom of the inner wall of the frame 100 and contacts the inner wall surface of the frame 100. At this time, the left scraper 209 slides inside the box 200 and the right scraper 211 slides inside the upper circular plate 208. At this time, the long scraper 212 fills the gap between the two ends of the vertical plate 105. At this time, the auxiliary scraper 201 and the long scraper 212 can adaptively fit into the gap between the bottom of the inner wall of the frame 100 to ensure the scraping effect of the material. When material leakage occurs at the gap between the vertical plate 105 and the bottom of the inner wall of the frame 100 during the scraping process, the vertical plate 105, the long scraper 212, etc., scrape the leakage again to ensure the scraping effect. For frames 100 of different widths, first remove the rubber sleeve 302 outside the locking stud 304, loosen the locking stud 304 by rotating it outward, release the fixation of the moving strip 303, and adjust the position of the moving strip 303 on the telescopic component on one side of the long scraper 212 (the moving strip 303 slides in the lower circular plate 301), drive the moving scraper 300 to move so that its outer end fits against the side wall of the frame 100. After adjustment, tighten the locking stud 304 to fix the position of the moving strip 303, and put the rubber sleeve 302 on the outer end of the locking stud 304. The rubber sleeve 302 at the end of the locking stud 304 can prevent dust from entering the threads. The telescopic component can be used to adapt to frames 100 of different widths and reduce material leakage from the side wall. During the auxiliary scraping process, an external air supply device is connected at the pipe 402, and then the waterproof motor 401 is started. The working end of the waterproof motor 401 rotates, driving the rotating rod 406 to rotate. The rotating rod 406 drives the hollow convex plate 403 below and the multiple sets of nozzles 409 on the hollow convex plate 403 to rotate and adjust the blowing tilt angle. After adjustment, the rotation stops, and then the two sets of hydraulic rods 407 are opened. The working end of the hydraulic rod 407 moves upward, driving the connecting frame and the baffle 405 and rubber plate 408 on the connecting frame to rise. Subsequently, the rubber plate 408 moves upward and disengages from the nozzle 409, exposing the nozzle 409. 09. At this time, the air supply equipment is turned on, and high-pressure gas enters the interior of the hollow convex plate 403. Compressed air is sprayed out through the nozzles 409 evenly distributed on one side of the hollow convex plate 403, which blows and cleans the surface of the T-shaped scraper driven by the chain 104 to rotate the T-shaped scraper. The material attached to the surface of the vertical plate 105, the auxiliary scraper 201, and the long scraper 212 is blown and cleaned. It can realize the blowing and cleaning during the auxiliary scraping process. When the equipment stops cleaning, it is operated according to the opposite principle. The hydraulic rod 407 on the hollow convex plate 403 drives the baffle 405 and the rubber plate 408 to move, covering the nozzles 409 to prevent blockage.
