[0049] Please refer to the attached instruction manual. Figures 1-11 The present invention provides a slag scraper conveyor, which includes a scraper conveyor 1, a feed box 2 and a conveying motor 3 installed on the scraper conveyor 1, a transmission box 4 installed between the scraper conveyor 1 and the conveying motor 3, and a motor shaft 5 installed on the conveying motor 3, the motor shaft 5 being installed inside the transmission box 4.

[0050] Furthermore, a transfer buffer box 6 is installed on the feed box 2, and an overload protection pushing mechanism 7 is installed on the transfer buffer box 6. The overload protection pushing mechanism 7 is used to push the slag into the feed box 2. Specifically, the overload protection pushing mechanism 7 includes an impact pushing box 701, which is movably installed in the transfer buffer box 6. A U-shaped pushing frame 707 is movably installed on the transfer buffer box 6. A horizontal pushing plate 706 for pushing the slag is installed on the U-shaped pushing frame 707. A horizontal pushing adapter rod 708 is movably installed on the motor shaft 5. The horizontal pushing adapter rod 708 is movably installed on the U-shaped pushing frame 707.

[0051] It should be noted that, in this embodiment of the invention, when the slag enters the feed box 2 during the operation of the scraper conveyor 1, it first falls into the impact pusher box 701, and drives the two impact frames 704 to move downward. At the same time, the two support springs 705 are stressed, thereby allowing the impact pusher box 701 to move downward automatically, increasing the storage capacity of the slag. This can effectively avoid the problem of slag not being discharged due to a sudden increase in slag volume during slag conveying. In addition, the impact pusher box 701 can also move upward automatically, thereby achieving the purpose of automatically replenishing slag when the slag volume is too low. In addition, when the scraper conveyor 1 is running, the conveyor motor 3 is started, and the motor shaft 5 drives the rotating push rod 710 to rotate. The rotation of the rotating push rod 710 drives the horizontal push transfer rod 708 to move through the rotating push shaft 711. The movement of the horizontal push transfer rod 708 pushes the horizontal push plate 706 to move through the U-shaped pusher frame 707. When the rotating push rod 710 continues to rotate, it drives the horizontal push plate 706 to move back and forth once, pushing the slag in the impact push box 701 into the feed box 2, so as to achieve the purpose of uniform slag feeding.

[0052] Please continue to refer to the instruction manual appendix. Figures 1-11 Furthermore, in the slag scraper conveyor provided in this embodiment of the invention, a feeding box 2 is equipped with a feeding grinding acceleration mechanism 8, which is used to grind and clear the slag. Specifically, the feeding grinding acceleration mechanism 8 includes a grinding screen plate 801, which is installed on the bottom side of the feeding box 2. Two arc-shaped guide plates 802 are installed inside the feeding box 2. U-shaped grinding plates 803 are slidably installed on the bottom side of both arc-shaped guide plates 802, and multiple grinding teeth 810 are installed on the bottom side of the U-shaped grinding plates 803. It should be noted that, in this embodiment of the invention, when the U-shaped pusher 707 moves, the two grinding pushers 804 drive the two U-shaped grinding plates 803 to move. The two U-shaped grinding plates 803 approach each other to squeeze and crush the slag. Furthermore, through the movement of the two U-shaped grinding plates 803, the U-shaped grinding plates 803 cooperate with the grinding screen plate 801 through multiple grinding teeth 810 to grind the slag. At the same time, this helps the ground slag enter the scraper conveyor, which can avoid the problem of the scraper conveyor being blocked due to the slag being too large.

[0053] More specifically, in this embodiment of the invention, a striking and unblocking mechanism 9 is also included. The striking and unblocking mechanism 9 is installed on one side of the feed box 2 and is used to strike the top side of the scraper conveyor 1. The striking and unblocking mechanism 9 includes a striking mounting frame 901, which is installed on one side of the feed box 2. Multiple transition lifting rods 902 are movably installed on the striking mounting frame 901. Synchronous striking bars 903 are installed on the bottom side of the multiple transition lifting rods 902. The synchronous striking bars 903 strike the top side of the scraper conveyor 1 to shake off the slag on the top side of the scraper conveyor 1. It should be noted that, in this embodiment of the invention, during slag feeding, the synchronous striking bar 903 is raised and lowered by the transfer lifting rod 902, thereby causing the synchronous striking bar 903 to strike the top side of the scraper conveyor 1. In the process of the linkage pusher 908 reciprocating, the above actions are repeated to strike the top side of the scraper conveyor 1 multiple times, so as to shake off the slag adhering to the scraper conveyor 1, and further ensure the smooth flow of the scraper conveyor 1.

[0054] Please refer to the instruction manual attached. Figure 2 and Figures 8-10 Furthermore, the slag scraper conveyor provided in this embodiment of the invention includes an overload prevention pushing mechanism 7 that further includes multiple water spray heads 712. The multiple water spray heads 712 are respectively installed on both sides of the impact pushing box 701. The bottom side of the impact pushing box 701 is hollow in a cross shape, and multiple drainage holes 714 are opened at the four corners of the bottom side of the impact pushing box 701.

[0055] In addition, a water inlet pipe 702 for water intake is connected to the bottom side of the impact pusher box 701, and a return water pipe 703 for drainage is installed on the bottom side of the transfer buffer box 6. It should be noted that, in this embodiment of the invention, when the scraper conveyor 1 is running, when the slag enters the feed box 2, it first falls into the impact pusher box 701. At this time, water enters through the water inlet pipe 702, and water is sprayed through multiple water nozzles 712 to cool the slag. Then, water is drained through multiple drainage holes 714, and then discharged through the return water pipe 703, thereby achieving the cooling of the slag.

[0056] For more details, please refer to the appendix to the instruction manual. Figures 2-7In this embodiment of the invention, two impact frames 704 are installed on the bottom side of the impact pusher box 701, and the impact frames 704 are movably mounted on the transfer buffer box 6. Furthermore, a support spring 705 is installed on the impact frame 704, and the support spring 705 is mounted on the bottom side of the transfer buffer box 6. It should be noted that in this embodiment of the invention, when slag enters the feed box 2, it first falls onto the impact pusher box 701. When the impact pusher box 701 is impacted, it causes the two impact frames 704 to move downwards, and the two support springs 705 are stressed. This allows the impact pusher box 701 to move downwards automatically, increasing the slag storage capacity and effectively preventing the problem of slag discharge failure caused by a sudden increase in slag volume during slag removal.

[0057] More specifically, in this embodiment of the invention, a rotating push rod 710 is mounted on the motor shaft 5, and the rotating push rod 710 is movably mounted on the transverse push adapter rod 708; a rotating push shaft 711 is movably mounted inside the transverse push adapter rod 708, and the rotating push shaft 711 is mounted on the rotating push rod 710. It should be noted that in this embodiment of the invention, when the motor shaft 5 rotates, it drives the rotating push rod 710 to rotate. The rotation of the rotating push rod 710 drives the transverse push adapter rod 708 to move via the rotating push shaft 711, and the rotating push shaft 711 slides within the transverse push adapter rod 708, thereby achieving the purpose of moving the transverse push plate 706 when the transverse push adapter rod 708 moves.

[0058] Please continue to refer to the instruction manual appendix. Figures 2-7 Furthermore, in the slag scraper conveyor provided in this embodiment of the invention, a transition groove 713 is provided on the U-shaped pusher frame 707, and a horizontal pusher adapter rod 708 is slidably installed in the transition groove 713; in addition, an transition spring 709 is installed on the inner wall of the transition groove 713, and the transition spring 709 is installed on the horizontal pusher adapter rod 708. It should be noted that, in this embodiment of the invention, when the rotating pusher rod 710 continues to rotate, the U-shaped pusher frame 707 is blocked by the transfer buffer box 6, causing the horizontal pusher adapter rod 708 to slide within the U-shaped pusher frame 707, and causing the transition spring 709 to contract under force, providing a buffer distance for the excessive movement of the horizontal pusher adapter rod 708.

[0059] Please refer to the instruction manual attached. Figure 2 and Figures 8-10 More specifically, in this embodiment of the invention, the feeding and grinding acceleration mechanism 8 further includes two grinding pushers 804, which are slidably mounted on both sides of the feeding box 2, and two U-shaped grinding plates 803 are mounted on the two grinding pushers 804 respectively.

[0060] Furthermore, a transverse pusher frame 808 is installed on the U-shaped pusher frame 707, and a transverse connecting pusher frame 806 is installed on the transverse pusher frame 808. Two wedge-shaped pushers 807 are installed on the transverse connecting pusher frame 806. The movement of the two wedge-shaped pushers 807 is used to compress the movement of the two grinding pushers 804. It should be noted that, in this embodiment of the invention, when the U-shaped pusher frame 707 moves, it simultaneously drives the transverse pusher frame 808 to move. The movement of the transverse pusher frame 808 drives the transverse connecting pusher frame 806 to move, so that the transverse connecting pusher frame 806 drives the two wedge-shaped pushers 807 to compress the movement of the two grinding pushers 804. The two grinding pushers 804 drive the movement of the two U-shaped grinding plates 803. The two U-shaped grinding plates 803 move closer to each other to compress the slag. And through the movement of the two U-shaped grinding plates 803, the U-shaped grinding plates 803 cooperate with the grinding screen plate 801 through multiple grinding teeth 810 to grind the slag, thereby achieving the purpose of crushing the slag.

[0061] More specifically, in this embodiment of the invention, two return springs 805 are installed on the U-shaped grinding plate 803, and the two return springs 805 are installed on the inner wall of the feed box 2; in addition, a limiting groove 811 is provided on the bottom side of the arc-shaped guide plate 802, and the U-shaped grinding plate 803 is slidably installed in the limiting groove 811. It should be noted that, in this embodiment of the invention, the return springs 805 can drive the U-shaped grinding plate 803 to reset, and the U-shaped grinding plate 803 slides horizontally within the limiting groove 811.

[0062] Please continue to refer to the attached diagrams in the instruction manual. Figure 2 and Figures 8-10 More specifically, in this embodiment of the invention, a transverse track 809 is installed on one side of the feed box 2, and a transverse push adapter 808 is slidably installed within the transverse track 809. It should be noted that in this embodiment of the invention, the transverse push adapter 808 slides horizontally within the transverse track 809 when it moves.

[0063] Further, please refer to the appendix to the instruction manual. Figure 2 and Figure 11In this embodiment of the invention, the impact unblocking mechanism 9 further includes multiple pulling plates 904, which are respectively installed on the top ends of multiple transition lifting rods 902. A retraction spring 905 is installed on the bottom side of the pulling plate 904, and the retraction spring 905 is installed on the top side of the impact mounting frame 901. It should be noted that in this embodiment of the invention, when the pulling plate 904 drives the transition lifting rod 902 upward, the retraction spring 905 is stretched by force. The movement of the transition lifting rod 902 drives the synchronous impact bar 903 upward. When the linkage push frame 908 continues to move, the arc-shaped push plate 909 disengages from a squeezing push roller 907. Then, under the contraction force of the retraction spring 905, the pulling plate 904, through the transition lifting rod 902, drives the synchronous impact bar 903 downward to impact the top side of the scraper conveyor 1, thereby achieving the purpose of unblocking the scraper conveyor 1.

[0064] Please continue to refer to the attached diagrams in the instruction manual. Figure 2 and Figure 11 More specifically, in this embodiment of the invention, each of the multiple pull plates 904 has a connecting shaft 906 installed on one side, and each of the multiple connecting shafts 906 has a pressing pusher 907 installed on it.

[0065] Furthermore, a linkage pusher 908 is installed on the transverse pusher frame 808, and an arc-shaped push plate 909 is installed on the linkage pusher 908. The movement of the linkage pusher 908 causes the arc-shaped push plate 909 to press the extrusion pusher 907 upward, thereby driving the striking mounting frame 901 to move. It should be noted that, in this embodiment of the invention, when the transverse pusher frame 808 moves, it drives the linkage pusher 908 to move, which in turn drives the arc-shaped pusher 909 to move. When the arc-shaped pusher 909 moves, it pushes an extrusion pusher 907 to move, causing the extrusion pusher 907 to drive the adapter shaft 906 to rotate on one side of the pull plate 904, and also driving the pull plate 904 to move. The pull plate 904 then drives the adapter lifting rod 902 to move, thereby achieving the purpose of driving the synchronous striking bar 903 upward through the movement of the adapter lifting rod 902.

[0066] In summary, the working principle of the slag scraper conveyor provided in this embodiment of the invention is as follows:

[0067] When the scraper conveyor 1 is running, the slag enters the feed box 2 and first falls into the impact push box 701. At this time, water enters through the water inlet pipe 702 and sprays water through multiple water spray heads 712 to cool the slag. Then, water is drained through multiple drain holes 714 and then discharged through the return water pipe 703.

[0068] Furthermore, when the impact pusher box 701 is impacted, it causes the two impact frames 704 to move downwards, and the two support springs 705 to be stressed. Therefore, under the rebound force of the two support springs 705, the impact pusher box 701 gradually resets as the slag decreases, which can effectively avoid the problem of slag not being discharged due to a sudden increase in slag volume. When the scraper conveyor 1 is running, the conveyor motor 3 starts, and drives the rotating push rod 710 to rotate through the motor shaft 5. The rotation of the rotating push rod 710 drives the horizontal pusher rod 708 to move through the rotating push shaft 711. The movement of the horizontal pusher rod 708 pushes the horizontal pusher plate 706 to move through the U-shaped pusher frame 707. It should be noted that when the rotating push rod 710 continues to rotate, the U-shaped pusher frame 707 is blocked by the transfer buffer box 6, causing the horizontal pusher rod 708 to slide inside the U-shaped pusher frame 707, and causing the transition spring 709 to contract under force, providing a buffer distance for the excessive movement of the horizontal pusher rod 708. Furthermore, when the motor shaft 5 drives the rotating push rod 710 to rotate one revolution, it drives the horizontal pusher plate 706 to move back and forth once, pushing the slag in the impact pusher box 701 into the feed box 2, thereby achieving the purpose of uniform slag feeding.

[0069] It should be further explained that when the U-shaped pusher frame 707 moves, it simultaneously drives the horizontal pusher adapter frame 808 to move, so that the horizontal pusher adapter frame 808 slides horizontally within the horizontal track 809. The movement of the horizontal pusher adapter frame 808 drives the horizontal connecting pusher frame 806 to move, so that the horizontal connecting pusher frame 806 drives the two wedge-shaped pushers 807 to squeeze the two grinding pushers 804 to move. The two grinding pushers 804 drive the two U-shaped grinding plates 803 to move, and cause the multiple retraction springs 805 to be stretched by force. The two U-shaped grinding plates 803 move closer to each other to squeeze the slag. Through the movement of the two U-shaped grinding plates 803, the U-shaped grinding plates 803 cooperate with the grinding screen plate 801 through multiple grinding teeth 810 to grind the slag. At the same time, it helps the ground slag to enter the scraper conveyor, which can avoid the problem of the scraper conveyor being blocked due to the size of the slag being too large.

[0070] Furthermore, when the transverse pusher frame 808 moves, it drives the linkage pusher frame 908 to move, which in turn drives the arc-shaped pusher plate 909 to move. When the arc-shaped pusher plate 909 moves, it pushes a pressing pusher 907 to move, which in turn drives the adapter shaft 906 to rotate on one side of the pull plate 904, and drives the pull plate 904 to move. The pull plate 904 drives the adapter lifting rod 902 to move, which causes the retraction spring 905 to be stretched. The movement of the adapter lifting rod 902 drives the synchronous striking bar 903 to move upward. It should be noted that when the linkage pusher 908 moves continuously, the arc-shaped pusher 909 disengages from a squeezing pusher 907. Then, under the contraction force of the retracting spring 905, the pulling plate 904 drives the synchronous striking bar 903 to move down through the transfer lifting rod 902 to strike the top side of the scraper conveyor 1. During the reciprocating movement of the linkage pusher 908, the above actions are repeated to strike the top side of the scraper conveyor 1 multiple times, thereby shaking off the slag adhering to the scraper conveyor 1 and further ensuring the smooth flow of the scraper conveyor 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
