Description

Technical Field

[0001] This utility model belongs to the field of monazite sanding technology, specifically relating to a feeding device for monazite sanding. Background Technology

[0002] Currently, monazite is mined in large pieces, but only in small pieces is it usable. This requires crushing the mined monazite before it can be fed into the machine. However, in existing equipment, crushing and feeding are carried out separately, which increases the cost and space required for the equipment. Furthermore, existing crushing methods typically use two meshing crushing rollers for compression and pulverization, but the hard and tough monazite raw material is prone to problems with insufficient crushing. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a feeding device for grinding monazite.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a feeding device for grinding monazite, comprising a screw conveyor, a support frame installed on the outer periphery of the screw conveyor, a feeding box installed and connected above the inlet end of the screw conveyor, a screening box installed and connected above the feeding box, a crushing mechanism installed and connected above the screening box, a rotating mechanism installed inside the screening box, a screening plate installed on the outer periphery of the rotating mechanism, and a collecting mechanism provided inside the feeding box.

[0005] Preferably, the crushing mechanism includes a crushing cylinder and an eccentric cylinder. The crushing cylinder is installed above the screening box. The outer periphery of the crushing cylinder has multiple through holes and a feed inlet. The eccentric cylinder is disposed inside the crushing cylinder and is eccentrically positioned with respect to the crushing cylinder. A drive motor is installed at the end of the crushing cylinder, and the output end of the drive motor is detachably connected to the side of the eccentric cylinder.

[0006] Preferably, the rotating mechanism includes a drive assembly and two connecting plates. Both connecting plates are installed inside the sieve box, and a rotating shaft passes through between the two connecting plates. The sieve plate is installed on the outer periphery of the rotating shaft, and the drive assembly is drivenly connected to the rotating shaft.

[0007] Preferably, the length of the feeding box is greater than the length of the screening box, a sliding groove is provided on the lower side of the screening box away from the connecting plate, a protrusion is installed on the side of the screening plate away from the rotating shaft, the protrusion cooperates with the sliding groove, and a vibrator is installed on the side of the screening plate.

[0008] Preferably, the drive assembly includes a disc, a ring, and a second bracket. The disc is mounted on the end of a rotating shaft, the second bracket is mounted on the outside of the feeding box, and a second drive motor is mounted above the second bracket. Multiple connecting posts are mounted on the side of the disc, the ring is located between two connecting posts separated by one connecting post, a connecting rod is mounted inside the ring, a pushing member is mounted on the side of the connecting rod, the pushing member cooperates with the outer periphery of the connecting post, the output end of the second drive motor is detachably connected to the middle position of the connecting rod, and a second through hole is opened on the side of the ring.

[0009] Preferably, the collecting mechanism includes a collecting plate, a sliding groove is provided on the side of the feeding box, the collecting plate is slidably connected in the sliding groove, and a second groove is provided on the top of the collecting plate.

[0010] Preferably, the screw conveyor is externally connected to a controller, and both the crushing mechanism and the rotating mechanism are communicatively connected to the controller.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] (1) In existing equipment, crushing and feeding are carried out separately. However, in this utility model, a feeding box, a screening box and a crushing mechanism are connected from top to bottom at the inlet end of the screw conveyor. By integrating crushing and feeding, the cost and placement space of the equipment can be reduced.

[0013] (2) Existing crushing usually uses two crushing rollers meshing, while the crushing mechanism in this utility model uses the eccentric setting of the crushing cylinder and the eccentric cylinder to make the eccentric cylinder form a dynamic extrusion space when it rotates at high speed. The monazite raw material not only bears the extrusion between the two, but also has a high frequency collision with the crushing cylinder wall due to centrifugal force. The dual crushing mechanism significantly improves the crushing efficiency and can fully crush the material.

[0014] (3) The through hole design on the outer periphery of the lower semicircle of the crushing cylinder ensures that the crushed material falls naturally into the screening box under the action of gravity, avoids material retention in the ineffective area of ​​the upper semicircle, and improves the continuity of the crushing process.

[0015] (4) The vibrator and the rotating mechanism on the outer periphery of the sieve plate work together. The vibrator causes the fine particles to pass through the sieve holes quickly and fall into the collection plate, reducing the phenomenon of particles getting stuck.

[0016] (5) When coarse particles need to be processed, the drive motor 2 drives the screen plate to rotate at a certain angle through the disc and ring transmission structure, so that the coarse particles on the screen plate slide down to the feed box, realizing the staged processing of coarse and fine particles, ensuring the efficient collection of fine particles, and avoiding the accumulation of coarse particles on the screen surface, thus improving the screening accuracy and efficiency.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the rotating mechanism includes a drive assembly and two connecting plates 15. Both connecting plates 15 are installed inside the sieve box 4. A rotating shaft 1 passes through the two connecting plates 15. A sieve plate 14 is installed on the outer periphery of the rotating shaft 1. The drive assembly is drivenly connected to the rotating shaft 1.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the length of the feeding box 3 is greater than the length of the sieve box 4. A sliding groove is provided on the lower side of the sieve box 4 away from the connecting plate 15. A protrusion 16 is installed on the side of the sieve plate 14 away from the rotating shaft, and the protrusion 16 cooperates with the sliding groove.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly includes a disc 7, a ring 8, and a bracket 2 12. The disc 7 is installed at the end of the rotating shaft 1, and the bracket 2 12 is installed on the outside of the feeding box 3. A drive motor 2 13 is installed above the bracket 2 12. Multiple connecting posts 11 are installed on the side of the disc 7. The ring 8 is located between two connecting posts 11 separated by one connecting post 11. A connecting rod 9 is installed inside the ring 8. A pusher 10 is installed on the side of the connecting rod 9. The pusher 10 cooperates with the outer periphery of the connecting post 11.

[0033] like Figure 1 and Figure 2 As shown, the collecting mechanism includes a collecting plate, a sliding groove is provided on the side of the feeding box 3, the collecting plate is slidably connected in the sliding groove, and a groove is provided on the top of the collecting plate.

[0034] In this utility model, multiple through holes are opened on the outer periphery of the lower semicircle of the crushing cylinder 5, and the crushing cylinder 5 is connected to the screening box 4 through the multiple through holes.

[0035] In this invention, when the ring 8 and multiple connecting posts 11 are engaged, the connecting post 11 closest to the connecting rod 9 is located inside the ring 8.

[0036] In this invention, the protrusion 16 can fit along the rotation axis in the arc of the groove.

[0037] In this invention, a vibrator is installed on the side of the sieve plate 14.

[0038] In this utility model, the screw conveyor 2 is externally connected to a controller, and both the crushing mechanism and the rotating mechanism are communicatively connected to the controller.

Afterwards, the staff will pull out the collection plate along the sliding groove, turn off the drive motor 6, and turn on the drive motor 13. The drive motor 13 will drive the connecting rod 9 to rotate the ring 8 until the pusher 10 engages with the connecting column 11 inside the ring 8, pushing the connecting column 11 to move. This will cause the disc 7 to rotate the rotating shaft 1, that is, the screen plate 14 will rotate at a certain angle. The crushed monazite raw material on the screen plate 14 will slide from the screen plate 14 into the feed box 3, and finally enter the screw conveyor 2. The screw conveyor 2 will be turned on to feed the crushed monazite raw material.

[0042] In this invention, the drive motor 213 needs to drive the disk 7 to rotate 90°.

[0043] In this invention, before the monazite raw material is fed in, the collecting plate needs to be slid into the sliding groove, and the feeding is achieved through this invention, requiring a suitable weight of monazite raw material to be fed in at one time.
