Description
Technical Field
[0001] This utility model relates to the field of discharge port anti-blocking technology, and in particular to an anti-blocking device for the discharge port of a destoner. Background Technology
[0002] A destoner is a device that removes impurities by utilizing the difference in density and suspension velocity between particulate materials and minerals, and by using mechanical wind power and a screen surface that moves back and forth along a certain trajectory to separate minerals from particulate materials.
[0003] When using existing destoners, materials tend to accumulate in the discharge port, causing blockage and making it difficult to discharge materials. This affects the destoner's discharge efficiency, requiring the machine to be stopped to unclog the discharge pipe before it can be used again, which wastes time. Utility Model Content

A piston seat is rotatably sleeved on the outside of the rotating shaft, and the spiral blade is located on the side of the piston seat facing the opening of the discharge cylinder. A horizontal positioning unit for positioning the piston seat is installed on the discharge cylinder.

[0021] This specification provides one or more embodiments of an anti-clogging device for the discharge port of a destoner, such as... Figure 1 and Figure 2As shown, the device includes a discharge cylinder 1, which is a hollow structure with one open end. A rotating shaft 2 is installed inside the discharge cylinder 1. A spiral blade 3 is fixedly sleeved on the outside of the rotating shaft 2. A piston seat 7 is rotatably sleeved on the outside of the rotating shaft 2, with the spiral blade 3 located on the side of the piston seat 7 facing the opening of the discharge cylinder 1. A horizontal positioning unit for positioning the piston seat 7 is installed on the discharge cylinder 1. A drive mechanism for driving the rotating shaft 2 to rotate is installed on the discharge cylinder 1. A discharge hole 4 is opened at the bottom of the inner wall of the discharge cylinder 1. Two side plates 5, adapted to the discharge hole 4, are fixedly connected to the bottom of the discharge cylinder 1. Two guide plates 6 are rotatably connected between the two side plates 5, and a mechanism for driving the guide plates 6 to swing is installed on the side plates 5. The structure features a swinging mechanism. The opening of the discharge cylinder 1 is fixedly connected to the discharge port of the destoner, and the ends of the rotating shaft 2 and the spiral blade 3 extend from the opening of the discharge cylinder 1 into the discharge port of the destoner. The operator positions the piston seat 7 and the rotating shaft 2 using a horizontal positioning unit to prevent the rotating shaft 2 from swaying relative to the discharge cylinder 1. The rotating shaft 2 and the spiral blade 3 are driven to rotate by a drive mechanism, and the spiral blade 3 is used to convey and discharge the grain particles. This avoids the problem of blockage at the discharge port of the destoner caused by the accumulation of grain particles. The grain entering the discharge cylinder 1 is finally discharged through the discharge hole 4, and the swinging structure drives the two guide plates 6 to swing, which facilitates the discharge of grain between the two side plates 5.
[0022] In embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the swing structure includes a translation frame 8 respectively disposed on the opposite side of the two guide plates 6. Two hydraulic telescopic rods 9 are fixedly connected to the opposite side of the two side plates 5, and the telescopic ends of the hydraulic telescopic rods 9 are fixedly connected to the corresponding translation frame 8. The translation frame 8 and the corresponding guide plate 6 are connected by a sliding member. The sliding member includes a slide plate 10 rotatably mounted on the translation frame 8. A first support part 11 is slidably sleeved on the outside of the slide plate 10, and the first support part 11 is fixedly connected to the guide plate 6. The translation frame 8 is driven to move horizontally by the hydraulic telescopic rods 9, and the translation frame 8 drives the slide plate 10 to move. The slide plate 10 rotates relative to the translation frame 8, and the tilt angle of the slide plate 10 changes. The slide plate 10 drives the tilt angle of the guide plate 6 to change synchronously through the first support part 11. The slide plate 10 slides relative to the first support part 11. The translation frame 8 is driven to move horizontally back and forth by the hydraulic telescopic rods 9, so that the guide plate 6 swings between the two side plates 5.
[0023] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the drive mechanism includes a servo motor 12 fixedly mounted on the discharge cylinder 1. A groove 13 is provided on the side of the rotating shaft 2 facing the servo motor 12. A prism 14 is slidably mounted in the groove 13, and the prism 14 is fixedly connected to the output end of the servo motor 12. The horizontal positioning unit includes two support bars 15 fixedly mounted on the side of the piston seat 7 away from the spiral blade 3. The end of the support bar 15 away from the piston seat 7 passes through the discharge cylinder 1. A lifting plate 17 is provided above the discharge cylinder 1. Two insert plates 18 are fixedly connected to the bottom of the lifting plate 17. Several insertion holes 19 adapted to the insert plates 18 are provided on the support bars 15. The bottom end of the insert plate 18 is located inside the discharge cylinder 1, and the bottom end of the insert plate 18 is located in the corresponding insertion hole 19. Two second support parts 20 are fixedly connected to the outer wall of the discharge cylinder 1. The top of the second support part 20 and the bottom of the lifting plate 17 are connected by a tension spring 21. A limiting sleeve 16 is slidably mounted on the outside of the support bar 15, and the limiting sleeve 16 is fixedly connected to the outer wall of the discharge cylinder 1. The sleeve 16 is fixedly connected to the outer wall of the discharge cylinder 1. The operator drives the lifting plate 17 and the insert plate 18 to move upward, and the tension spring 21 is in a stretched state so that the bottom end of the insert plate 18 disengages from the corresponding insertion hole 19, releasing the positioning of the support bar 15 and the piston seat 7. The operator pushes the piston seat 7 and the rotating shaft 2 relative to the discharge cylinder 1 through the support bar 15. The support bar 15 slides relative to the limiting sleeve 16. The design of the limiting sleeve 16 increases the stability of the support bar 15 when moving horizontally. The rotating shaft 2 drives the slide groove 13 to slide relative to the prism 14. After the position of the rotating shaft 2 is adjusted, the operator releases the lifting plate 17, and the tension spring 21 drives the lifting plate 17 and the insert plate 18 to move downward so that the bottom end of the insert plate 18 is inserted into the corresponding insertion hole 19, thus fixing the piston seat 7 relative to the discharge cylinder 1. The prism 14 is driven to rotate by the servo motor 12, and the prism 14 can drive the rotating shaft 2 and the spiral blade 3 to rotate synchronously through the slide groove 13.
