TECHNICAL FIELD

[0001] The utility model relates to the scraper technology field of material taking machine especially relates to a recyclable half door type material taking machine scraper. BACKGROUND

[0002] Steel plant has a large amount of bulk material to carry out stacking, storing and taking operation every day, and the half door type material taking machine is a device commonly used for bulk material taking operation.

[0003] The related art has a Chinese patent with the authorization announcement number CN211971065U, which provides a half door type scraper material taking machine device, which includes a portal, the top end of the portal is connected with the top end of the swing end beam through the thrust bearing, the swing end beam is installed on the high platform and connected with the track on the upper surface of the high platform, the bottom end of the portal is connected with the fixed end beam, the fixed end beam is connected with the track on the ground, the platform is welded on the fixed end beam, the side plate is hinged on the platform, the steel wire rope is installed between the side plate and the portal, a plurality of internal rollers are installed between the side plates, the external part of the internal rollers is collectively sleeved with the conveying belt, a plurality of scrapers are uniformly installed on the external part of the conveying belt, and the discharge rubber belt machine is installed on one side of the fixed end beam and below the side plate. The material surface below the side plate is taken into a certain depth and remains unchanged, and the conveying belt starts to circulate, so that the scrapers scrape the material onto the discharge rubber belt machine, which is transported out by the discharge rubber belt machine; after taking out one layer of material, the side plate is lowered by a corresponding height, and the scrapers scrape the material onto the discharge rubber belt machine again under the driving of the conveying belt, so that the material pile is taken out layer by layer until all the material in the bin is taken out.

[0004] In the process of implementing the present application, the inventors found that in the use process of the scraper, the scraper contacts the material and generates friction, which causes the surface of the scraper to be worn and shortens the service life of the scraper, so the scraper needs to be replaced frequently, making it difficult to reduce the loss cost of the half door type material taking machine. UTILITY MODEL CONTENTS

[0005] In order to prolong the service life of the scraper and reduce the loss cost of the half door type material taking machine, the present application provides a recyclable half door type material taking machine scraper.

[0006] The recyclable half door type material taking machine scraper provided by the present application adopts the following technical solution:

[0007] A recyclable semi-gantry material handling scraper includes a scraper plate, a reinforcing component on one side of the scraper plate to improve its strength, and several liners on the other side of the scraper plate with their bottoms protruding from the bottom of the scraper plate. Several first mounting components are provided between the liners and the scraper plate to allow for detachable connection between the liners and the scraper plate. Several rake teeth are provided on the side of the liners away from the scraper plate with their bottoms protruding from the bottom of the liners. A second mounting component is provided between the rake teeth and the liners to allow for detachable connection between the rake teeth and the liners.

[0008] By adopting the above technical solution, a scraper is installed on a semi-gantry reclaimer. The scraper drives the liner and rake teeth to move, scraping the material onto the discharge conveyor belt. During the scraping process, the rake teeth loosen the material, and the liner replaces the scraper in contact with the material, thereby reducing material wear on the scraper. Simultaneously, the reinforced components improve the overall structural stability and extend the scraper's service life. When the liner wears out, the first mounting component moves the liner's position on the scraper, ensuring the lower end of the liner protrudes beyond the bottom of the scraper, thus reducing liner wear. Instead of discarding the liner plate directly after wear, the service life of the liner plate is extended. Then, the installation position of the rake teeth on the liner plate is moved by the second mounting component, so that the lower end of the rake teeth protrudes from the bottom of the liner plate. When the rake teeth wear down, the installation position of the rake teeth on the liner plate is moved by the second mounting component, so that the lower end of the rake teeth protrudes from the bottom of the liner plate. This reduces the situation where the rake teeth are discarded directly after wear, and extends the service life of the rake teeth. By extending the service life of the liner plate and the rake teeth, the service life of the scraper of the semi-gantry reclaimer is extended, and the wear and tear cost of the semi-gantry reclaimer is reduced.

[0009] Preferably, the scraper includes a top plate, a horizontal plate, and a set of side plates. The top of the horizontal plate and the top of the side plates are fixedly connected to the bottom of the top plate. One end of the horizontal plate is fixedly connected to one of the side plates, and the other end of the horizontal plate is fixedly connected to the other side plate. The side plates are arranged opposite each other, and the opposite surfaces of the side plates are lateral scraping surfaces. A set of mounting seats is fixedly provided on one side of the horizontal plate, and the other side of the horizontal plate is a transverse scraping surface. The transverse scraping surface is located between the lateral scraping surfaces, and the included angle between the transverse scraping surface and the lateral scraping surface is an obtuse angle. The liner is detachably mounted on the transverse scraping surface and the lateral scraping surface.

[0010] By adopting the above technical solution, the top plate, the horizontal plate and the side plate together form a scraper, which facilitates the scraping of materials.

[0011] Preferably, the reinforcing component includes a plurality of first transverse ribs, a plurality of first longitudinal ribs, a plurality of second transverse ribs, a plurality of second longitudinal ribs, and a reinforcing rib plate. The first transverse ribs and first longitudinal ribs are fixedly disposed on the side of one side plate away from the liner, and the first transverse ribs are perpendicular to each other. The second transverse ribs and second longitudinal ribs are fixedly disposed on the side of the other side plate away from the liner, and the second transverse ribs are perpendicular to each other. The reinforcing rib plate is fixedly disposed on the side of the transverse plate away from the liner, and the reinforcing rib plate is fixedly connected to the mounting base. The cross-section of the reinforcing rib plate is triangular.

[0012] By adopting the above technical solution, the first transverse rib and the first longitudinal rib are installed on one side plate, and the second transverse rib and the second longitudinal rib are installed on the other side plate, thereby strengthening the structural stability of the side plate. The reinforcing ribs are installed on the transverse plate, thereby improving the structural stability of the transverse plate, reducing the deformation of the scraper, and achieving the effect of improving the strength of the scraper.

[0013] Preferably, the first mounting assembly includes a first mounting screw, a first mounting nut, and a first mounting head. The first mounting head is fixedly disposed at one end of the first mounting screw. The first mounting screw is threadedly connected to the first mounting nut. A plurality of first fixing circular holes are formed through the horizontal plate and the side plate. The diameter of the first fixing circular holes is the same as the diameter of the first mounting screw. A plurality of first fixing elongated holes are formed through the liner. The width of the first fixing elongated holes is the same as the diameter of the first mounting screw. The length of the first fixing elongated holes is greater than the diameter of the first mounting screw. The first mounting screw is inserted into both the first fixing circular holes and the first fixing elongated holes. The side of the first mounting nut facing the first mounting head is used to abut against the side of the horizontal plate away from the liner. The side of the first mounting nut facing the first mounting head is used to abut against the side of the side plate away from the liner. The side of the first mounting head facing the first mounting nut is used to abut against the liner on the horizontal plate. The side of the first mounting head facing the first mounting nut is used to abut against the liner on the side plate.

[0014] By adopting the above technical solution, when the liner is installed on the horizontal plate, the liner is positioned opposite to the transverse scraping surface, and the first fixing elongated hole on the liner is positioned opposite to the first fixing round hole on the horizontal plate. Then, the first mounting screw passes through the oppositely positioned first fixing round hole and first fixing elongated hole, and the first mounting screw head abuts the liner against the transverse scraping surface. Afterwards, the first mounting nut is threaded onto the first mounting screw, so that the side of the first mounting nut facing the first mounting screw head abuts against the side of the horizontal plate away from the liner. When the liner is installed on the side plate, the liner is positioned opposite to the lateral scraping surface, and the first fixing elongated hole on the liner is positioned opposite to the first fixing round hole on the side plate. The round holes are arranged opposite each other. Then, the first mounting screw is passed through the first fixed round hole and the first fixed elongated hole, and the first mounting screw head is made to abut the liner against the side scraping surface. Then, the first mounting nut is threaded onto the first mounting screw, so that the side of the first mounting nut facing the first mounting screw head abuts against the side of the side plate away from the liner. Since the width of the first fixed elongated hole is equal to the diameter of the first mounting screw, and the length of the first fixed elongated hole is greater than the diameter of the first mounting screw, the installation position of the liner on the scraper can be changed by adjusting the relative position of the first mounting screw in the first fixed elongated hole, so that the lower end of the liner remains protruding from the bottom of the scraper.

[0015] Preferably, a first receiving groove is formed on the inner wall of the first fixed elongated hole. The first receiving groove penetrates the side wall of the liner away from the first fixed circular hole. The width of the first receiving groove is the same as the diameter of the first mounting screw head. The length of the first receiving groove is greater than the length of the first fixed elongated hole. The depth of the first receiving groove is greater than the thickness of the first mounting screw head. The first receiving groove is for inserting the first mounting screw rod and the first mounting screw head. The inner wall of the first receiving groove is used to abut against the side of the first mounting screw head facing the first mounting nut.

[0016] By adopting the above technical solution, after the liner is locked onto the horizontal plate and the side plate, the first mounting screw head is located in the first receiving groove. When scraping the material, the material fills the first receiving groove, thereby reducing the wear on the first mounting screw head and the first receiving groove.

[0017] Preferably, the second mounting assembly includes a second mounting screw, a second mounting nut, and a second mounting head. The second mounting head is fixedly disposed at one end of the second mounting screw. The second mounting screw is threadedly connected to the second mounting nut. A first fixing circular hole is formed through the rake teeth. The diameter of the second fixing circular hole is the same as the diameter of the second mounting screw. A plurality of second fixing elongated holes are formed through the liner. The width of the second fixing elongated holes is the same as the diameter of the second mounting screw. The length of the second fixing elongated holes is greater than the diameter of the second mounting screw. The second mounting screw is inserted into both the second fixing circular hole and the second fixing elongated hole. The side of the second mounting nut facing the second mounting head is used to abut against the side of the liner away from the rake teeth. The side of the second mounting head facing the second mounting nut is used to abut against the rake teeth on the liner.

[0018] By adopting the above technical solution, when installing the rake teeth on the liner, the rake teeth are positioned opposite the side of the liner away from the scraper, and the second fixing round hole on the rake teeth is positioned opposite the second fixing elongated hole on the liner. Then, the second mounting screw passes through the oppositely positioned second fixing round hole and second fixing elongated hole, and the second mounting screw head abuts the rake teeth against the liner. Afterward, the second mounting nut is threaded onto the second mounting screw, so that the side of the second mounting nut facing the second mounting screw head abuts against the side of the liner away from the rake teeth. Since the width of the second fixing elongated hole is equal to the diameter of the second mounting screw, and the length of the second fixing elongated hole is greater than the diameter of the second mounting screw, the installation position of the rake teeth on the liner can be changed by adjusting the relative position of the second mounting screw in the second fixing elongated hole, so that the lower end of the rake teeth remains protruding from the bottom of the liner.

[0019] Preferably, a second receiving groove is formed on the inner wall of the second fixed circular hole. The second receiving groove penetrates the side wall of the rake tooth away from the second fixed elongated hole. The width of the second receiving groove is the same as the diameter of the second mounting screw head. The length of the second receiving groove is greater than the length of the second fixed elongated hole. The depth of the second receiving groove is greater than the thickness of the second mounting screw head. The second receiving groove is for the insertion of the second mounting screw and the second mounting screw head. The inner wall of the second receiving groove is used to abut against the side of the second mounting screw head facing the second mounting nut.

[0020] By adopting the above technical solution, when the rake teeth are locked on the liner, the second mounting screw head is located in the second receiving groove. When scraping the material, the material fills the second receiving groove, thereby reducing the wear on the second mounting screw head and the second receiving groove.

[0021] Preferably, a positioning groove is formed on the inner wall of the second fixed elongated hole. The positioning groove penetrates the bottom of the liner and the side of the liner away from the scraper plate. The inner wall of the positioning groove is used to fit against the outer wall of the rake teeth.

[0022] By adopting the above technical solution, the positioning groove facilitates the positioning and installation of the rake teeth. When scraping materials, the materials fill the positioning groove, thereby reducing the wear on the inner wall of the positioning groove.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up scraper blades, reinforcing components, liners, first mounting components, rake teeth, and second mounting components, the service life of the scraper blades of the semi-gantry reclaimer is extended, and the wear and tear costs of the semi-gantry reclaimer are reduced.

[0025] 2. By setting a first mounting screw, a first mounting nut, a first mounting screw head, a first fixing round hole and a first fixing elongated hole, the liner is installed on the scraper plate, and by adjusting the relative position of the first mounting screw in the first fixing elongated hole, the installation position of the liner on the scraper plate is changed so that the lower end of the liner plate remains protruding from the bottom of the scraper plate;

[0026] 3. By setting a second mounting screw, a second mounting nut, a second mounting screw head, a second fixing round hole, and a second fixing elongated hole, the rake teeth are installed on the liner plate.

[0036] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0037] This application discloses a recyclable scraper for a semi-gantry material handling machine. (Refer to...) Figure 1 and Figure 2The system includes a scraper 1, which comprises a top plate 11, a horizontal plate 12, and a set of side plates 13. The tops of the horizontal plate 12 and the side plates 13 are welded to the bottom of the top plate 11. One end of the horizontal plate 12 is welded to one of the side plates 13, and the other end is welded to the other side plate 13. The side plates 13 are arranged opposite each other, and their opposite surfaces form a lateral scraping surface 131. A set of mounting bases 14 for connecting to a semi-gantry reclaimer is installed on one side of the horizontal plate 12, and the other side of the horizontal plate 12 forms a transverse scraping surface 121. The transverse scraping surface 121 is located between the lateral scraping surfaces 131, and the angle between the transverse scraping surface 121 and the lateral scraping surface 131 is an obtuse angle. Liners 3 are installed on both the transverse scraping surface 121 and the lateral scraping surface 131. The bottom of the liner 3 installed on the horizontal plate 12 protrudes from the bottom of the horizontal plate 12, and the bottom of the liner 3 installed on the side plates 13 protrudes from the bottom of the side plates 13. A plurality of first mounting components 5 are installed on the liner plate 3. The first mounting components 5 are used to detachably install the liner plate 3 onto the side plate 13 and the cross plate 12. A plurality of positioning grooves 41 are formed on the side of the liner plate 3 away from the cross plate 12 and the side plate 13. The positioning grooves 41 penetrate through the bottom of the liner plate 3. A plurality of rake teeth 4 are detachably installed in the positioning grooves 41, and the bottom of the rake teeth 4 protrudes from the bottom of the liner plate 3. The positioning grooves 41 facilitate the positioning and installation of the rake teeth 4. When scraping materials, the materials fill the positioning grooves 41, thereby reducing the wear on the inner wall of the positioning grooves 41. A second mounting component 6 is provided between the rake teeth 4 and the liner plate 3. The second mounting component 6 is used to detachably connect the rake teeth 4 and the liner plate 3. The scraper 1 is installed on the semi-gantry reclaimer. The scraper 1 drives the liner 3 and rake teeth 4 to move, scraping the material onto the discharge conveyor belt. During the scraping process, the rake teeth 4 loosen the material, and the liner 3 replaces the scraper 1 in contact with the material, thereby reducing material wear on the scraper 1 and extending its service life. When the liner 3 wears out, the first mounting component 5 moves the liner 3 on the scraper 1 so that the lower end of the liner 3 protrudes beyond the bottom of the scraper 1, thus reducing the likelihood of the liner 3 being discarded after wear and extending its service life. Then, the second mounting component 6 moves the rake teeth 4 on the liner 3 so that the lower end of the rake teeth 4 protrudes beyond the bottom of the liner 3. When the rake teeth 4 wears out, the second mounting component 6 moves the rake teeth 4 on the liner 3 so that the lower end of the rake teeth 4 protrudes beyond the bottom of the liner 3, thus reducing the likelihood of the rake teeth 4 being discarded after wear and extending its service life. By extending the service life of the liner plate 3 and the rake teeth 4, the service life of the scraper of the semi-gantry reclaimer is extended, and the wear and tear cost of the semi-gantry reclaimer is reduced.

[0038] To improve the overall stability of the scraper structure of the semi-gantry reclaimer, referring to... Figure 1 and Figure 2A reinforcing component 2 is installed on the side of the scraper 1 away from the liner 3. The reinforcing component 2 includes several first transverse ribs 21, several first longitudinal ribs 23, several second transverse ribs 22, several second longitudinal ribs 24, and a reinforcing rib plate 25. The first transverse ribs 21 and first longitudinal ribs 23 are welded to one side plate 13 away from the liner 3, and the first transverse ribs 21 and first longitudinal ribs 23 are perpendicular to each other. The second transverse ribs 22 and second longitudinal ribs 24 are welded to the other side plate 13 away from the liner 3, and the second transverse ribs 22 and second longitudinal ribs 24 are perpendicular to each other. The reinforcing rib plate 25 is installed on the side of the transverse plate 12 away from the liner 3 and is welded to the mounting base 14. The reinforcing rib plate 25 has a triangular cross-section. The first transverse ribs 21 and first longitudinal ribs 23 are installed on one side plate 13, and the second transverse ribs 22 and second longitudinal ribs 24 are installed on the other side plate 13, thereby enhancing the structural stability of the side plate 13. The reinforcing ribs 25 are installed on the horizontal plate 12, thereby improving the structural stability of the horizontal plate 12. This reduces the deformation of the scraper plate 1, thus increasing its strength.

[0039] To facilitate changing the installation position of the liner 3 on the scraper 1, refer to... Figures 1 to 7The first mounting assembly 5 includes a first mounting screw 51, a first mounting nut 52, and a first mounting head 53. The first mounting head 53 is mounted on one end of the first mounting screw 51, and the diameter of the first mounting head 53 is larger than the diameter of the first mounting screw 51. The first mounting screw 51 is threadedly connected to the first mounting nut 52. A plurality of first fixing circular holes 54 are formed through the horizontal plate 12 and the side plate 13. The diameter of the first fixing circular holes 54 is the same as the diameter of the first mounting screw 51. A plurality of first fixing elongated holes 55 are formed through the liner 3. The width of the first fixing elongated holes 55 is the same as the diameter of the first mounting screw 51, and the length of the first fixing elongated holes 55 is greater than the diameter of the first mounting screw 51. When installing the liner 3 on the horizontal plate 12, the liner 3 is positioned opposite to the transverse scraping surface 121, and the first fixing elongated hole 55 on the liner 3 is positioned opposite to the first fixing round hole 54 on the horizontal plate 12. Then, the first mounting screw 51 passes through the oppositely positioned first fixing round hole 54 and first fixing elongated hole 55, and the first mounting screw head 53 abuts the liner 3 against the transverse scraping surface 121. After that, the first mounting nut 52 is threaded onto the first mounting screw 51, so that the side of the first mounting nut 52 facing the first mounting screw head 53 abuts against the side of the horizontal plate 12 away from the liner 3. When installing the liner 3 on the side plate 13, the liner 3 is positioned opposite the lateral scraping surface 131, and the first fixing elongated hole 55 on the liner 3 is positioned opposite the first fixing round hole 54 on the side plate 13. Then, the first mounting screw 51 is passed through the oppositely positioned first fixing round hole 54 and first fixing elongated hole 55, and the first mounting screw head 53 abuts the liner 3 against the lateral scraping surface 131. Afterward, the first mounting nut 52 is threaded onto the first mounting screw 51, so that the side of the first mounting nut 52 facing the first mounting screw head 53 abuts against the side of the side plate 13 away from the liner 3. Since the width of the first fixing elongated hole 55 is equal to the diameter of the first mounting screw 51, and the length of the first fixing elongated hole 55 is greater than the diameter of the first mounting screw 51, the installation position of the liner 3 on the scraper plate 1 can be changed by adjusting the relative position of the first mounting screw 51 in the first fixing elongated hole 55, so that the lower end of the liner 3 remains protruding from the bottom of the scraper plate 1.

[0040] To extend the service life of the first mounting screw head 53, refer to Figures 1 to 7A first receiving groove 56 is formed on the inner wall of the first fixed elongated hole 55, penetrating the side wall of the liner 3 away from the first fixed circular hole 54. The width of the first receiving groove 56 is the same as the diameter of the first mounting screw head 53, the length of the first receiving groove 56 is greater than the length of the first fixed elongated hole 55, and the depth of the first receiving groove 56 is greater than the thickness of the first mounting screw head 53. The first receiving groove 56 is for inserting the first mounting screw 51 and the first mounting screw head 53, and the inner wall of the first receiving groove 56 is used to abut against the side of the first mounting screw head 53 facing the first mounting nut 52. When the liner 3 is locked onto the horizontal plate 12 and the side plate 13, the first mounting screw head 53 is located in the first receiving groove 56. When scraping materials, the materials fill the first receiving groove 56, thereby reducing the wear on the first mounting screw head 53 and the first receiving groove 56.

[0041] To facilitate changing the installation position of the rake teeth 4 on the liner plate 3, refer to... Figures 1 to 8 The second mounting assembly 6 includes a second mounting screw 61, a second mounting nut 62, and a second mounting head 63. The second mounting head 63 is mounted on one end of the second mounting screw 61, and the diameter of the second mounting head 63 is larger than the diameter of the second mounting screw 61. The second mounting screw 61 is threadedly connected to the second mounting nut 62. A first fixing circular hole 54 is formed through the rake teeth 4, and the diameter of the second fixing circular hole 64 is the same as the diameter of the second mounting screw 61. A second fixing elongated hole 65 is formed in the positioning groove 41, and the second fixing elongated hole 65 penetrates the liner plate 3. The width of the second fixing elongated hole 65 is the same as the diameter of the second mounting screw 61, and the length of the second fixing elongated hole 65 is greater than the diameter of the second mounting screw 61. When installing the rake teeth 4 in the positioning groove 41 onto the liner 3, the second fixing round hole 64 on the rake teeth 4 is positioned opposite to the second fixing elongated hole 65 on the liner 3. Then, the second mounting screw 61 passes through the oppositely positioned second fixing round hole 64 and second fixing elongated hole 65, and the second mounting screw head 63 abuts the rake teeth 4 against the liner 3. Afterward, the second mounting nut 62 is threaded onto the second mounting screw 61, so that the side of the second mounting nut 62 facing the second mounting screw head 63 abuts against the side of the liner 3 away from the rake teeth 4. Since the width of the second fixing elongated hole 65 is equal to the diameter of the second mounting screw 61, and the length of the second fixing elongated hole 65 is greater than the diameter of the second mounting screw 61, the installation position of the rake teeth 4 on the liner 3 can be changed by adjusting the relative position of the second mounting screw 61 within the second fixing elongated hole 65.

[0042] To extend the service life of the second mounting screw head 63, refer to Figures 1 to 8A second receiving groove 66 is formed on the inner wall of the second fixed circular hole 64. The second receiving groove 66 penetrates the side wall of the rake tooth 4 away from the second fixed elongated hole 65. The width of the second receiving groove 66 is the same as the diameter of the second mounting screw head 63, the length of the second receiving groove 66 is greater than the length of the second fixed elongated hole 65, and the depth of the second receiving groove 66 is greater than the thickness of the second mounting screw head 63. The second receiving groove 66 is for inserting the second mounting screw 61 and the second mounting screw head 63. The inner wall of the second receiving groove 66 is used to abut against the side of the second mounting screw head 63 facing the second mounting nut 62. When the rake tooth 4 is locked on the liner plate 3, the second mounting screw head 63 is located in the second receiving groove 66. When scraping material, the material fills the second receiving groove 66, thereby reducing the wear on the second mounting screw head 63 and the second receiving groove 66.

[0043] The implementation principle of a recyclable semi-gantry reclaimer scraper according to an embodiment of this application is as follows: A scraper 1 is installed on the semi-gantry reclaimer. The scraper 1 drives the liner 3 and rake teeth 4 to move, scraping the material onto the discharge conveyor belt. During the scraping process, the rake teeth 4 loosen the material, and the liner 3 replaces the scraper 1 in contact with the material, thereby reducing material wear on the scraper 1. Simultaneously, the first transverse rib 21, the first longitudinal rib 23, the second transverse rib 22, the second longitudinal rib 24, and the reinforcing rib 25 improve the strength of the scraper 1 and the stability of the overall structure, extending the service life of the scraper 1. When the liner 3 wears down, the installation position of the liner 3 on the scraper 1 is first moved by the first mounting component 5, so that the lower end of the liner 3 remains protruding from the bottom of the scraper 1, thereby reducing the direct discarding of the liner 3 after wear and extending its service life. Then, the installation position of the rake teeth 4 on the liner 3 is moved by the second mounting component 6, so that the lower end of the rake teeth 4 remains protruding from the bottom of the liner 3. When the rake teeth 4 wear down, the second mounting assembly 6 moves the installation position of the rake teeth 4 on the liner plate 3, keeping the lower end of the rake teeth 4 protruding from the bottom of the liner plate 3. This reduces the likelihood of the rake teeth 4 being discarded directly after wear, extending their service life. By extending the service life of the liner plate 3 and the rake teeth 4, the service life of the scraper of the semi-gantry reclaimer is extended, and the wear and tear costs of the semi-gantry reclaimer are reduced.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
