The vibrating feeder used in mining is used to evenly or quantitatively feed materials from the storage bin or other storage equipment to the receiving equipment. It is an essential equipment for the automation of assembly line operation.
[0003] The feeder consists of a rotatable disc, a guide sleeve and a scraper. The material in the silo is accumulated on the disc with a wear-resistant lining through the guide sleeve. The disc rotates and the material is scraped out by the scraper for feeding. The feeding amount can be changed by adjusting the position of the scraper or the height of the guide sleeve. The diameter of the disc is generally less than 3 meters and the speed does not exceed 10 rpm. The disc feeder runs smoothly and reliably, the feeding amount is easy to adjust, and the energy consumption is low, but the structure is relatively bulky and suitable for powdery and granular materials with less viscosity.
[0004] The disc screen of the feeder has a much different overall appearance than the plate screen. When cleaning the disc screen, you can clean the meshes one by one in the assembled state, or clean the entire screen in the disassembled state. To clean a disc screen that is partially blocked or blocked over a large area, this method requires suspending the equipment, which can easily affect the continuous production work.

DETAILED DESCRIPTION
[0026] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0027] Embodiment 1:
[0028] This embodiment introduces a specific structure of a feeder with a disc screen self-cleaning mechanism. Figure 1-Figure 5As shown, it includes a disc screen body 1 applied to the feeder, including a cleaning grid frame 2 arranged at the bottom of the disc screen body 1 and a screw-like sleeve 12 sleeved inside the cleaning grid frame 2, a plurality of cleaning heads 3 are processed on the top of the cleaning grid frame 2, a first fixed plate 4 is arranged at the center of the bottom of the disc screen body 1, a rotating shaft 8 is processed on the bottom surface of the first fixed plate 4, two spiral grooves are processed on the outer wall of the screw-like sleeve 12, and a controlled seat 13 is movably connected inside the two spiral grooves;
[0029] like Figure 1 and Figure 2 As shown, the disc screen body 1 includes a screen 102, a ring frame 101 is processed on the outer side of the screen 102, and a center disc 103 is processed on the inner side of the screen 102;
[0030] The first fixed disk 4 is assembled and connected to the bottom of the center disk 103. By connecting the two ends of the two spiral grooves on the screw-like sleeve 12 respectively, when one end of the controlled seat 13 is pinned to the inside of the cleaning grid 2, the rotating shaft 8 can control the screw-like sleeve 12 to rotate in the process of the rotating shaft 8 driving the entire disc screen body 1 to rotate through the first fixed disk 4 and the center disk 103, so that the controlled seat 13 is guided by the spiral groove to reciprocate up and down, driving the cleaning head 3 on the top of the cleaning grid 2 to clean the blockage inside the disc screen body 1.
[0031] At the same time, in order to ensure the cleaning effect of the blockage, such as Figure 2 As shown, the multiple cleaning heads 3 are all conical in shape. By making the multiple cleaning heads 3 correspond to the multiple meshes in the screen 102 one by one, the tip of the cleaning head 3 can be used to push out the blockage in the mesh when the cleaning frame 2 drives the multiple cleaning heads 3 to reciprocate up and down.
[0032] Secondly, in order to make the rotating shaft 8 synchronously drive the screw-like sleeve 12 to rotate, such as Figure 4 and Figure 5 As shown, the outer wall of the rotating shaft 8 is processed with a second limiting groove 15, and the inner wall of the screw-like sleeve 12 is processed with a first limiting groove 5. The second limiting groove 15 and the first limiting groove 5 are pinned with the same pin key 6. By pinning the same pin key 6 between the second limiting groove 15 and the first limiting groove 5, the rotating shaft 8 and the screw-like sleeve 12 are connected and fixed. When the rotating shaft 8 rotates, the screw-like sleeve 12 can be driven to rotate;
[0033] Furthermore, the rotating shaft 8 drives the screw-like sleeve 12 to rotate inside the supporting sleeve 7. In order to make the controlled seat 13 move up and down under the influence of the spiral groove on the screw-like sleeve 12 during the process of the rotating shaft 8 driving the screw-like sleeve 12 to rotate, as shown in FIG. Figure 4 and Figure 5As shown, the outer part of the screw-like sleeve 12 is sleeve-connected with the support sleeve 7, and a limit groove 11 is provided at one end of the support sleeve 7. By making the middle part of the controlled seat 13 slidably connected to the inside of the limit groove 11, when the rotating shaft 8 drives the screw-like sleeve 12 to rotate, the controlled seat 13 can be controlled to slide up and down inside the limit groove 11 by means of the spiral groove.
[0034] By adopting the above technical solution:
[0035] The above-mentioned design is achieved by arranging a cleaning grid frame 2 at the bottom of the disc screen body 1, and connecting a screw-like sleeve 12 through a controlled seat 13 inside the cleaning grid frame 2. When the rotating shaft 8 drives the disc screen body 1 to rotate, the screw-like sleeve 12 is synchronously driven to rotate by means of the pin key 6 pinned to the rotating shaft 8 and the screw-like sleeve 12. The spiral groove on the outer wall of the screw-like sleeve 12 cooperates with the controlled seat 13, and the controlled seat 13 cooperates with the limiting groove 11 at one end of the support sleeve 7 (fixed installation). The cleaning grid frame 2 reciprocates up and down on the outside of the support sleeve 7, thereby driving multiple cleaning heads 3 to push the blockages in the mesh of the screen 102 to the top at fixed time intervals, without manual operation, and suspending the feeder.
[0036] Embodiment 2:
[0037] Based on Example 1, this example introduces the specific structure of the support sleeve 7. A second fixed plate 9 is processed at one end of the support sleeve 7. A spring 10 is arranged between the second fixed plate 9 and the cleaning grid 2.
[0038] Among them, by assembling and fixing the second fixed plate 9 with the feeder, it can be ensured that the controlled seat 13 cooperates with the limiting groove 11 at one end of the supporting sleeve 7. In the process of the rotating shaft 8 driving the screw-like sleeve 12 to rotate, the controlled seat 13 is controlled by the spiral groove on the outer wall of the screw-like sleeve 12 to drive the cleaning grid 2 to reciprocate up and down inside the limiting groove 11;
[0039] At the same time, in order to balance the gravity of the cleaning grid 2 and the cleaning head 3, it is prevented that the cleaning grid 2 is connected to the screw-like sleeve 12 through the controlled seat 13, and the screw-like sleeve 12 has a tendency to move toward the bottom outside the rotating shaft 8 due to the influence of a large gravity. Figure 2 and Figure 4 As shown, the spring 10 is used to form a support between the second fixed plate 9 and the cleaning grid 2, which is beneficial to balance the gravity of the cleaning grid 2 and the cleaning head 3 as much as possible with the help of the spring 10, and does not affect the up and down movement of the cleaning grid 2 outside the support sleeve 7;
[0040] Secondly, in order to prevent one end of the spring 10 from interfering with the bolts used to fix the second fixing plate 9, as shown in FIG. Figure 4As shown, the surface of the second fixed plate 9 is processed with an isolation ring 14. By sleeve-fitting one end of the spring 10 on the inner side of the isolation ring 14, isolation can be formed between the spring 10 and the bolt to form protection.
[0041] By adopting the above technical solution:
[0042] The above-mentioned design processes a second fixed plate 9 at one end of the support sleeve 7 and sleeves a spring 10 on the outside of the support sleeve 7 so that it is supported between the cleaning grid 2 and the second fixed plate 9. This is beneficial for balancing the gravity of the cleaning grid 2 and the cleaning head 3 as much as possible with the help of the spring 10, and when the cleaning grid 2 is controlled to reciprocate up and down outside the support sleeve 7, the spring 10 can be compressed, which will not affect the function of the cleaning grid 2 to drive the cleaning head 3 to normally clean the internal mesh of the screen 102.
[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
