[0050] In some embodiments, in combination with Figure 1 and Figure 2As shown in the figure, a scraper crushing and transferring machine 100 is provided, which includes a machine body 110, a scraper drive assembly 120, a material crushing mechanism 130, a receiving hopper 140, and a magnetic separator 150. The machine body 110 includes a chute 111. The scraper drive assembly 120 is arranged on the machine body 110 and located inside the chute 111, and the scraper drive assembly 120 is used for conveying materials. The material crushing mechanism 130 is arranged on the machine body 110 and located above the chute 111, and is used for crushing the passing materials. The receiving hopper 140 is arranged on the machine body 110, located above the chute 111 and communicated with the chute 111, and is used for receiving materials. The magnetic separator 150 is arranged on the machine body 110, located above the chute 111 and on the discharge side of the chute 111.

[0051] For the scraper crushing and transferring machine 100 provided by the present disclosure, the machine body 110 is provided with a chute 111 extending from the feeding end to the discharging end. A receiving hopper 140 is arranged above the chute 111 at the feeding end. The end face area of the upper end of the receiving hopper 140 is larger than the end face area of the end connected to the chute 111, and the side wall is arranged in an inclined shape. The receiving hopper 140 is used for collecting the mined materials, and the materials are conveyed to the discharging end through the scraper drive assembly 120 arranged in the chute 111. A crushing mechanism is also arranged between the receiving hopper 140 and the discharging end. The crushing mechanism is arranged across the chute 111 above the chute 111. There is a spacing between the crushing mechanism and the chute 111, and the spacing is adjustable, and the height can be set according to the type of mined ore materials to achieve effective crushing of the passing materials. After the materials pass through the crushing mechanism, the large-volume materials can be crushed and then smoothly conveyed to the next connecting device through the scraper drive assembly 120. In this way, it is avoided that the material blocks are too large, resulting in overflowing of the transfer machine, improving the smoothness of material conveying and the safety for the staff during the material conveying process.

[0052] Furthermore, in combination with Figure 1 As shown in the figure, at the discharging end of the chute 111, a magnetic separator 150 is arranged across the chute 111 along the width direction of the chute 111. The magnetic separator 150 can remove the iron parts in the passing materials, avoiding the iron parts from entering the scraper drive assembly 120, thereby causing jamming of the scraper drive assembly 120 and improving the running stability of the scraper crushing and transferring machine 100.

[0053] Optionally, in combination with Figures 1 to 5 As shown in the figure, the scraper drive assembly 120 includes a driving device 121, a transmission sprocket 122, a scraper chain 123, and a drag chain device 124. The driving device 121 is arranged on the machine body 110. The transmission sprocket 122 is connected to the output end of the driving device 121. The scraper chain 123 is wound around the transmission sprocket 122. The drag chain device 124 is arranged on the machine body 110. The drag chain device 124 includes a drag chain plate 125, and the drag chain plate 125 is arranged on one side of the transmission sprocket 122.

[0054] In this embodiment, the components for realizing material conveyance are arranged to include a driving device 121, and the output end of the driving device 121 is connected to the scraper chain wheel 123. The driving device 121 is used to drive the rotation of the scraper chain wheel 123, and then drive the rotation of the scraper chain 123 wound around the scraper chain wheel 123, thereby realizing the conveyance of materials.

[0055] Further, as Figures 3 to 5 shown, the scraper driving assembly 120 further includes a drag chain device 124. The drag chain device 124 is arranged on the machine body 110. The drag chain device 124 includes a drag chain plate 125, and an arc-shaped groove is arranged on one side of the drag chain plate 125 facing the driving sprocket 122. The arc length groove is adapted to the side wall of the transmission shaft of the driving sprocket 122. The arc-shaped groove is arranged corresponding to the side wall of the tooth side of the driving sprocket 122, and there is a gap between the bottom of the arc-shaped groove and the side wall, and the gap is smaller than the height of the tooth. In this way, when the driving sprocket 122 rotates, it drives the rotation of the scraper chain 123 wound around the teeth. By arranging the drag chain plate 125 on the inner side of the rotation of the driving sprocket 122, the drag chain plate 125 can prevent the return part of the scraper chain 123 from continuing to rotate upward following the driving sprocket 122 and avoid the occurrence of hinge conditions, so that the scraper chain 123 can be smoothly transmitted.

[0056] Optionally, a groove is formed at the bottom of the chute 111, and the groove is used to install the drag chain device 124.

[0057] Optionally, as Figures 3 to 5 shown, the drag chain device 124 further includes: a drag chain seat 126 and a plug 127.

The plug 127 is connected to the machine body 110 and is located in the groove. The plug 127 and the drag chain seat 126 are arranged side by side on one side of the groove located in the chute 111. Among them, the plug 127 and the drag chain seat 126 are arranged side by side on one side of the groove located in the chute 111 to block the opening on one side of the groove located in the chute 111.

[0058] In this embodiment, the drag chain device 124 includes a drag chain seat 126, a drag chain plate 125 and a plug 127. The drag chain plate 125 is arranged on the drag chain seat 126. The drag chain seat 126 and the plug 127 are respectively detachably connected to the machine body 110. And both the drag chain seat 126 and the plug 127 are located in the groove. Among them, the groove opens towards one side of the chute 111, and by arranging the plug 127 and the drag chain seat 126 side by side, the opening is blocked, so that the residue of the conveyed material can be prevented from falling into the lower space, thereby affecting the normal operation of other components.

[0059] Further, the drag chain seat 126 and the plug 127 are respectively installed on the machine body 110 by screws. And the plug 127 is located on the side of the drag chain seat 126 away from the transmission sprocket 122. Since the drag chain plate 125 is relatively easy to be damaged, the drag chain device 124 needs to be frequently replaced. When replacing, first remove the plug 127 to release the groove space, then disassemble the drag chain seat 126. After releasing the screws, move the drag chain seat 126 to the other side of the groove, and the removal of the drag chain device 124 can be realized. Compared with the related art, in which the drag chain device 124 can be replaced only after the transmission sprocket 122 is disassembled. By adopting the drag chain device 124 of the present disclosure, the replacement method of the drag chain device 124 is simplified, the labor intensity of workers is reduced, and the work efficiency is improved.

[0061] In this embodiment, along the extension direction of the chute 111, the length of the plug 127 is set to be greater than the distance from the end of the drag chain plate 125 to the side wall of the transmission sprocket 122 located on one side of the drag chain plate 125, so as to provide sufficient operating space for the disassembly and installation of the drag chain seat 126, and improve the convenience of the disassembly and installation of the drag chain device 124.

[0062] Optionally, the width of the drag chain seat 126 is greater than the width of the drag chain plate 125. The width of the drag chain seat 126 is equal to or slightly less than the width of the groove to achieve the sealing effect of the groove, and at the same time can meet the installation space requirements of the drag chain seat 126. The width of the drag chain seat 126 is greater than the width of the drag chain plate 125, so that during the replacement of the drag chain device 124, sufficient moving space can be provided for the drag chain plate 125 to realize the smooth replacement of the drag chain device 124.

[0063] Optionally, in combination with Figure 1 As shown, the iron remover 150 includes a support seat 151 and an iron removing plate 152.
