The impact frame is provided with a supporting spring, and the supporting spring is installed on the bottom side of the transfer buffer box.

[0008] Further, in the preferred embodiment of the present application, the motor rotating shaft is provided with a rotating push rod, and the rotating push rod is movably installed on the horizontal pushing connecting rod. The horizontal pushing connecting rod is movably provided with a rotating push shaft, and the rotating push shaft is installed on the rotating push rod.

[0009] Further, in the preferred embodiment of the present application, the U-shaped pushing frame is provided with an excess sliding groove, and the horizontal pushing connecting rod is slidably installed in the excess sliding groove. The excess sliding groove is provided with an excess spring on the inner wall, and the excess spring is installed on the horizontal pushing connecting rod.

[0010] Further, in the preferred embodiment of the present application, the feeding grinding acceleration mechanism further comprises two grinding pushers, the two grinding pushers are slidingly installed on the two sides of the feeding box, and the two U-shaped grinding plates are installed on the two grinding pushers, respectively.

A retraction spring is installed on the bottom side of the pulling plate, and the retraction spring is installed on the top side of the knocking mounting frame.

[0014] Further, in the preferred embodiment of the present application, a plurality of adapter rotating shafts are installed on one side of the plurality of pulling plates, and a plurality of extrusion pushing wheels are installed on the adapter rotating shafts. A linkage pushing frame is installed on the horizontal pushing adapter, an arc-shaped pushing plate is installed on the linkage pushing frame, and the linkage pushing frame moves to extrude the extrusion pushing wheel on the arc-shaped pushing plate to move upward, so as to drive the knocking mounting frame to move.

[0015] The slag scraper conveyor has the following advantages: In the present application, when the slag scraper conveyor is running, the slag falls into the impact pushing box, so that the impact pushing box is impacted and drives the two impact frames to move downward, and then the two supporting springs are stressed, so that the impact pushing box can automatically move downward, thereby increasing the storage capacity of the slag, and effectively avoiding the problem that the slag cannot be discharged due to sudden increase of the slag amount during slag discharge; in addition, when the slag scraper conveyor is running, the conveying motor is started, and when the motor shaft drives the rotating push rod to rotate one revolution, the horizontal pushing plate reciprocates once, and the slag in the impact pushing box is pushed into the feeding box, thereby achieving the purpose of uniform slag feeding and ensuring smooth feeding of the feeding box.

[0016] Furthermore, in this invention, by setting up a feeding and grinding acceleration mechanism, when the U-shaped pusher moves, it synchronously drives the horizontal pusher frame to move, and the movement of the horizontal pusher frame drives the movement of the transverse connecting pusher frame. The transverse connecting pusher frame drives two wedge-shaped pushers to squeeze the two grinding pushers, so that the two grinding pushers drive the two U-shaped grinding plates to move. The two U-shaped grinding plates move closer to each other to squeeze the slag. In addition, by moving the two U-shaped grinding plates, the U-shaped grinding plates cooperate with the grinding screen plate through multiple grinding teeth to grind the slag, and help the ground slag enter the scraper conveyor. This can avoid the problem of the scraper conveyor being blocked due to the size of the slag being too large, and can also effectively avoid the accumulation and blockage of slag, ensuring that the scraper conveyor can continuously transport slag.

[0017] Furthermore, in this invention, by setting up a striking and unblocking mechanism, when the transverse pusher frame moves, it drives the linkage pusher frame to move, which in turn drives the arc-shaped push plate to move. When the arc-shaped push plate moves, it pushes a squeezing pusher to move, which in turn drives the transfer shaft to rotate on one side of the pulling plate, and drives the pulling plate to move. The pulling plate drives the transfer lifting rod to move, and causes the retracting spring to be stretched. The movement of the transfer lifting rod causes the synchronous striking bar to move upward. When the linkage pusher frame continues to move, the arc-shaped push plate disengages from a squeezing pusher. Then, under the contraction force of the retracting spring, the pulling plate drives the synchronous striking bar to move downward through the transfer lifting rod to strike the top side of the scraper conveyor. During the reciprocating movement of the linkage pusher frame, the above actions are repeated to strike the top side of the scraper conveyor multiple times, thereby shaking off the slag adhering to the scraper conveyor and further ensuring the smooth flow of the scraper conveyor.

It should be noted that when the rotating push rod 710 continuously rotates, the U-shaped pushing frame 707 is blocked by the intermediate transfer buffer box 6, so that the horizontal push adapter rod 708 slides in the U-shaped pushing frame 707, and the excessive spring 709 is stressed to contract, which provides a buffer distance for the excessive movement of the horizontal push adapter rod 708, and when the motor shaft 5 drives the rotating push rod 710 to rotate one circle, the horizontal pushing plate 706 reciprocates once, the slag in the impact pushing box 701 is pushed into the feeding box 2, and the purpose of uniform slag feeding is achieved; Further need to be explained is that when the U-shaped pushing frame 707 moves, the synchronous belt drives the horizontal pushing transfer frame 808 to move, so that the horizontal pushing transfer frame 808 slides horizontally in the horizontal moving track 809, and the horizontal pushing transfer frame 808 drives the horizontal linkage pushing frame 806 to move, so that the horizontal linkage pushing frame 806 drives the two wedge-shaped pushing seats 807 to extrude the two grinding pushing frames 804 to move, the two grinding pushing frames 804 drive the two U-shaped grinding plates 803 to move, and the plurality of retractable springs 805 are stretched under force, the two U-shaped grinding plates 803 are close to each other to extrude the slag, and through the movement of the two U-shaped grinding plates 803, the U-shaped grinding plate 803 grinds the slag by cooperating with the grinding sieve plate 801 through the plurality of grinding tooth blocks 810, and helps the ground slag enter into the scraper conveyor, so that the problem of blockage of the scraper conveyor caused by the size of the slag is avoided. Further, when the horizontal pushing transfer frame 808 moves, the linkage pushing frame 908 is driven to move, so that the linkage pushing frame 908 drives the arc-shaped pushing plate 909 to move, the arc-shaped pushing plate 909 drives one extrusion pushing wheel 907 to move when moving, so that the extrusion pushing wheel 907 drives the transfer shaft 906 to rotate on one side of the pulling plate 904, and drives the pulling plate 904 to move, the pulling plate 904 drives the transfer lifting rod 902 to move, and the retractable spring 905 is stretched under force, the transfer lifting rod 902 drives the synchronous beating strip 903 to move upward. It should be noted that when the linkage pushing frame 908 continuously moves, the arc-shaped pushing plate 909 is separated from one extrusion pushing wheel 907, and then under the contraction force of the retractable spring 905, the pulling plate 904 drives the synchronous beating strip 903 to move downward through the transfer lifting rod 902 to beat the top side of the scraper conveyor 1, and in the process of reciprocating movement of the linkage pushing frame 908, the above-mentioned action is repeated to beat the top side of the scraper conveyor 1 for multiple times, so that the slag adhered to the scraper conveyor 1 is shaken off, and the smoothness of the scraper conveyor 1 is further ensured.
