Technical Field

[0001] The present application relates to the field of material sorting devices, and in particular to a guiding structure for a moving pallet of a coal and gangue sorting device. Background Art

[0002] Coal and gangue sorting devices usually require a moving pallet to achieve the transportation and sorting of materials, and the guiding structure plays a crucial role in ensuring that the pallet can move stably and accurately to the target position.

[0003] For example, in the moving pallet structure of a coal and gangue sorting combination device with the patent number 202223427731.3, which includes a receiving plate, a support pipe, a position and shape maintaining bin, a connecting plate, and a housing, there are still the following deficiencies in actual use:

[0004] When the moving pallet structure of the coal and gangue sorting device of the above patent is actually used, the telescopic movement is carried out through the direct sliding contact between the support pipe and the maintaining bin. The control effect on linearity is small. And in daily use, the receiving plate does not need to be fully extended for sorting work. This structure has poor control over telescoping, and due to the large wear rate between the sliding connection parts, the service life is short. Summary of the Utility Model

[0005] In order to improve the poor controllability and easy wear of parts, the present application provides a guiding structure for a moving pallet of a coal and gangue sorting device.

[0019] By adopting the above technical solution, the limiting square groove limits the bottom limiting wheel, making the movement direction more accurate.

[0020] Preferably, the through connecting screw also passes through the side wall of the telescopic strip and is threadedly connected to the telescopic strip. A sliding block is fixedly connected between the two connecting plates. The middle of the sliding block is slidably connected to the limiting column, and a fixing block is fixedly connected to the side wall of the limiting guide rod.

[0021] By adopting the above technical solution, the limiting guide rod fixes the fixing block, making the position of the limiting guide rod more stable and the stress distribution more uniform.

[0022] Preferably, one side of the fixed block away from the limit guide rod is fixedly connected to the inner cavity side wall of the device housing.

[0038] The embodiment of this application discloses a guiding structure for a moving pallet of a coal and gangue sorting device.

[0039] Embodiment 1

[0040] Referring to Figure 1 , a guiding structure for a moving pallet of a coal and gangue sorting device includes a device housing 1. A telescopic strip 3 is slidably connected through the middle of the device housing 1 for telescopic screening movement. One end side wall of the telescopic strip 3 away from the device housing 1 is fixedly connected to the connecting end of a connecting long plate 4 through a bolt connection. The top of the connecting long plate 4 is fixedly connected to the bottom of a loading plate 5 through welding or bolt connection for receiving the materials to be sorted out. A guiding and limiting mechanism 2 is arranged inside the device housing 1.

[0041] Through the above settings, after the staff starts the device, the guiding and limiting mechanism 2 will drive the telescopic strip 3 to perform a linear horizontal movement. The telescopic strip 3 will drive the connecting long plate 4 to perform a horizontal movement synchronously. The connecting long plate 4 will drive the loading plate 5 to perform a horizontal movement, thereby driving the loading plate 5 to extend to carry the materials to be sorted out.

[0042] Referring to Figure 2, 3, 4, 5, The guiding and limiting mechanism 2 includes a servo motor 21 fixedly connected to the bottom of the device housing 1. The output shaft end of the servo motor 21 passing through the bottom of the device housing 1 is fixedly connected to the synchronous pulley 22 by welding. The side wall of the synchronous pulley 22 is meshed and sleeved with the toothed plate 23 through teeth, so that the rotation is more stable. A square groove is opened on one side of the clamping plate 24 close to the toothed plate 23. The outer side wall of the toothed plate 23 is clamped with the clamping plate 24 through the square groove opened by the clamping plate 24, so that the contact surface fits more closely. Vertical teeth are opened on one side of the replication plate 25 close to the toothed plate 23 for fitting. The inner side wall of the toothed plate 23 is meshed and connected with the replication plate 25 through the vertical teeth opened on the side wall of the replication plate 25, so as to clamp from both sides. Threaded through holes are opened on the side wall of the clamping plate 24. The connecting bolt 26 passes through the threaded through holes opened on the side wall of the clamping plate 24 and is threadedly connected with the clamping plate 24. Threaded holes are opened on the side wall of the replication plate 25. The connecting bolt 26 is threadedly connected with the replication plate 25 through the threaded holes opened on the side wall of the replication plate 25. Thus, the toothed plate 23 is clamped and fitted on both sides through the connecting bolt 26, making the connection more stable. The bottom of the clamping plate 24 is fixedly connected to the top of the top plate 27 by welding or bolt connection. The bottom of the replication plate 25 abuts against the top of the top plate 27. The bottom of the top plate 27 is fixedly connected to the top of the connecting plate 28 by welding for connection with the telescopic strip 3. Circular through holes are opened on the side wall of the connecting plate 28. A rotating shaft is rotatably connected in the circular through holes on the side wall of the connecting plate 28. A top limiting wheel 29 is rotatably connected between the two connecting plates 28 through the rotating shaft. The bottom of the top limiting wheel 29 is movably connected to the limiting column 210 through fitting friction, so as to prevent the connecting plate 28 from having a vertical displacement. The limiting column 210 is fixedly connected to the inner cavity side wall of the device housing 1 by welding or bolt connection for limiting. The bottom of the limiting column 210 is movably connected to the top of the bottom limiting wheel 211 through fitting friction, so as to fit the bottom of the limiting column 210. A square groove is opened on the top of the limiting square groove 212. The bottom of the bottom limiting wheel 211 is slidably connected to the limiting square groove 212 through the square groove, so as to restrict the movement direction of the bottom limiting wheel 211. The bottom of the limiting square groove 212 is fixedly connected to the bottom of the inner cavity of the device housing 1 by welding. Threaded through holes are opened on the side wall of the connecting plate 28. The connecting plate 28 passes through the threaded through holes on the side wall and is threadedly connected with the penetrating connecting screw 213, making the connection tighter. Threaded through holes are opened on the side wall of the telescopic strip 3. The penetrating connecting screw 213 also passes through the threaded through holes opened on the side wall of the telescopic strip 3 and is threadedly connected with the telescopic strip 3. The two connecting plates 28 are fixedly connected to both sides of the sliding block 214 by welding for clamping and limiting. A through hole is opened through the middle of the sliding block 214. The middle of the sliding block 214 is slidably connected to the limiting column 210 through the through hole, so as to restrict the movement of the connecting plate 28. The side wall of the limiting guide rod 217 is fixedly connected to the fixed block 218 by welding,One side of the fixed block 218 away from the limit guide rod 217 is fixedly connected to the inner cavity side wall of the device housing 1 by welding or bolts, so as to bear the stress of each section of the limit guide rod 217, and keep the top plate 27 continuously fitting the top and bottom of the pulley 216. One side of the top plate 27 close to the inner wall of the device housing 1 penetrates through the fixing member 219 and is fixedly connected to the fixing member 219 by welding. The side wall of the fixing member 219 is fixedly connected to the inner cavity side wall of the device housing 1 by welding, so as to fix the limit guide rod 217. Threaded through holes are provided on the side wall of the connecting plate 28. The side wall of the connecting plate 28 penetrates through the threaded through holes to realize threaded connection with the fixing screw 220. The fixing screw 220 penetrates through one side wall of the telescopic strip 3 and realizes threaded connection with the telescopic strip 3, so that the connecting plate 28 and the side wall of the telescopic strip 3 are integrated, which is convenient for driving movement.

[0043] Through the above settings, the servo motor 21 will be started by the staff. Subsequently, the output shaft of the servo motor 21 will rotate. The end of the output shaft of the servo motor 21 will drive the synchronous pulley 22 to rotate. After the synchronous pulley 22 rotates, it will drive the toothed plate 23 to transmit through meshing. When the toothed plate 23 transmits, the toothed plate 23 will perform a linear motion. The toothed plate 23 will drive the clamping plate 24 and the copying plate 25 to perform linear motion synchronously. The clamping plate 24 will drive the top plate 27 to perform linear motion synchronously. The top plate 27 will drive the connecting plate 28 to perform linear motion. The connecting plate 28 will drive the telescopic strip 3 to perform linear motion. The horizontal movement of the connecting plate 28 will also drive the top limit wheel 29 to rotate on the top of the limit column 210. At the same time, the bottom limit wheel 211 will fit the bottom of the limit column 210 to rotate, so as to engage the connecting plate 28 and the limit column 210 to prevent the connecting plate 28 from having a vertical displacement phenomenon. At the same time, the through screw 215 is threadedly connected to the telescopic strip 3, and the telescopic strip 3 will drive the through screw 215 to perform a horizontal motion.

[0044] Refer to Figure 6 , 7, the guiding and limiting mechanism 2 further includes a through screw 215 threadedly connected to the side wall of the telescopic strip 3. The outer wall of the other end of the through screw 215 penetrating through the telescopic strip 3 is set as a smooth surface. The side wall of the other end of the through screw 215 penetrating through the telescopic strip 3 is rotatably connected to the pulley 216 through the set smooth surface, so as to facilitate the rotation of the pulley 216 and improve the rationality of the structure. The outer wall of the other end of the through connecting screw 213 penetrating through the telescopic strip 3 is set as a smooth surface. The other end of the through connecting screw 213 penetrating through the telescopic strip 3 is also rotatably connected to another pulley 216, making the rotation more stable. The top and bottom of the pulley 216 are both rotatably connected to the limit guide rod 217 through fitting friction, so that the pulley 216 can only rotate horizontally.

[0045] With the above settings, when the through screw 215 moves horizontally, it will drive the pulley 216 to rotate. As the pulley 216 moves horizontally, it will directly rotate between the two limit guide rods 217 and restrict the linear movement of the telescopic strip 3, making the movement of the structure more stable. The fitting of the pulley 216 will also prevent the telescopic strip 3 from directly contacting the guiding component, thereby reducing material loss.

[0046] Among them, the device also includes an internal coupling, a motor plate, a switch, and a servo motor 21, etc., which are all prior arts, and their structural principles will not be elaborated here.

[0047] The implementation principle of the guiding structure of the movable pallet of the coal and gangue sorting device in the embodiment of the present application is as follows:

[0048] The servo motor 21 drives the synchronous wheel 22 to rotate, so that the clamping plate 24 moves linearly. Then, the clamping plate 24 drives the connecting plate 28 to move linearly horizontally, thereby driving the telescopic strip 3 to move horizontally. By the fitting of the top limit wheel 29 and the bottom limit wheel 211 to the limit column 210, the connecting plate 28 can only drive the telescopic strip 3 to move horizontally. Subsequently, the telescopic strip 3 drives the material loading plate 5 to move horizontally to perform the material sorting work.

[0049] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
