Description

Technical Field

[0001] The utility model relates to the technical field of classifier feeding, in particular to a classifier with an auxiliary feeding function. Background Art

[0002] Classifiers operate by exploiting the different settling velocities of solid particles of varying size and specific gravity in liquids. Fine particles float in the water and overflow, while coarse particles sink to the bottom of the trough. Mechanical structures such as screws push the coarse particles upward for discharge, achieving material classification. They are widely used in a variety of fields, including metal beneficiation, non-metallic minerals, chemicals, food, and pharmaceuticals, for processes such as mineral grading, desliming, dehydration, and concentration.

[0003] Publication number CN 221268902 U discloses a classifier with a hopper function. The classifier has a material shaking function and a material shaking mechanism at its feed port, which increases the feeding speed of the feed port, improves the efficiency of the classifier, facilitates material unloading, is not prone to clogging, and is easy to use.

[0004] The classifier is specially equipped with a hopper function to ensure that the ore sand is not easily blocked during the discharge process. However, there are many types of ore sand, especially when the ore sand contains a high moisture content, it is easy to form lumps. Once the ore sand lumps block the discharge port, it is difficult to effectively loosen the agglomerated ore sand even through shaking equipment, which makes the discharge port at the bottom of the material box easily blocked, so improvement is needed.

[0015] Compared with the prior art, the present invention provides a classifier with auxiliary feeding function, which has the following beneficial effects:

[0016] 1. The classifier with auxiliary feeding function pours the material to be screened into the storage hopper through the provided pressing discharging mechanism.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0029] The utility model provides the following technical solutions: Example 1

[0030] See also Figure 1-6 The utility model provides a technical solution: a classifier with auxiliary feeding function, comprising a classifier body 1, a collecting mechanism 2 is arranged inside the classifier body 1, a material guide plate 3 is fixedly connected to the right side of the classifier body 1, a material storage hopper 4 is fixedly connected to the top of the material guide plate 3, and a pressing discharge mechanism 5 is arranged inside the material storage hopper 4;

[0031] The pressing and discharging mechanism 5 includes a pressing component 51 and a discharging component 52. The pressing component 51 is arranged on the right side of the storage hopper 4, and the discharging component 52 is arranged at the bottom of the storage hopper 4.

[0032] The pressing assembly 51 includes an arc-shaped plate 516, which is fixedly connected to the right side of the storage hopper 4. The front side of the arc-shaped plate 516 is fixedly connected to the first motor 519, and the back end of the first motor 519 is fixedly connected to the rotating shaft 517. The rotating shaft 517 is rotatably connected to the inner side of the arc-shaped plate 516. A gear 518 is fixedly connected to the middle of the outer periphery of the rotating shaft 517. A rack plate 515 is meshed with the left side of the gear 518. The left side of the rack plate 515 is fixedly connected to the lifting plate 512. The bottom of the lifting plate 512 is fixedly connected to the fixing rod 513. The bottom of the fixing rod 513 is fixedly connected to the pressing disk 511. The inner side of the rack plate 515 is slidably connected to the limiting rod 5191. The top and bottom of the limiting rod 5191 are fixedly connected to the hollow plate 514. The hollow plate 514 is fixedly connected to the right side of the inside of the storage hopper 4. The first spring 5192 is sleeved on the outer periphery of the limiting rod 5191.

[0033] Furthermore, a sliding groove corresponding to the movement trajectory of the rack plate 515 is opened inside the hollow plate 514, and the rack plate 515 is slidably connected inside the sliding groove. Through the opened sliding groove, the rack plate 515 can slide inside the hollow plate 514, making the rack plate 515 more stable during the movement.

[0034] Furthermore, the top of the first spring 5192 is fixedly connected to the bottom of the lifting plate 512, and the bottom of the first spring 5192 is fixedly connected to the bottom of the hollow plate 514. When the first motor 519 stops operating, the elastic force of the first spring 5192 enables the rack plate 515 to drive the lifting plate 512, the fixed rod 513 and the pressing plate 511 to move upward, so that the pressing plate 511 can return to its original position, making it difficult for the pressing plate 511 to block the material inside the storage hopper 4 from being discharged. Example 2

[0035] See also Figure 1-6, and on the basis of Example 1, it is further obtained that the discharging component 52 includes a first connecting plate 521, the first connecting plate 521 is fixedly connected to the left side of the storage hopper 4, the front of the first connecting plate 521 is fixedly connected to the second motor 524, the back end of the second motor 524 is fixedly connected to the bidirectional threaded rod 523, the bidirectional threaded rod 523 is rotatably connected to the inner side of the first connecting plate 521, the outer periphery of the bidirectional threaded rod 523 is threadedly connected to the threaded plate 522, the inner side of the threaded plate 522 is fixedly connected to a baffle 525, the right side of the baffle 525 is fixedly connected to a sliding plate 528, the sliding plate 528 is slidably connected to a connecting rod 527, the front and rear sides of the connecting rod 527 are fixedly connected to the second connecting plate 526, and the second connecting plate 526 is fixedly connected to the right side of the storage hopper 4.

[0036] Furthermore, the baffle 525 is arranged at the bottom of the storage hopper 4, and the top of the baffle 525 is in contact with the bottom of the storage hopper 4. By adjusting the position of the baffle 525, the size of the opening at the bottom of the storage hopper 4 can be adjusted, so that the device can control the amount of material discharged. Example 3

[0037] See also Figure 1-6 On the basis of Example 1, the collecting mechanism 2 is further obtained to include a guide rod 23, the guide rod 23 is fixedly connected to the inside of the classifier body 1, the outer periphery of the guide rod 23 is slidably connected to a slider 22, the top of the slider 22 is fixedly connected to a collecting box 21, the collecting box 21 is slidably connected to the inside of the classifier body 1, the front of the collecting box 21 is fixedly connected to a pull plate 25, and the outer periphery of the guide rod 23 is sleeved with a second spring 24.

[0038] Furthermore, the front end of the second spring 24 is fixedly connected to the front of the classifier body 1, and the back end of the second spring 24 is fixedly connected to the front of the slider 22. When the staff does not pull the collection box 21, the elastic force of the second spring 24 enables the slider 22 to drive the collection box 21 to be retracted into the classifier body 1, so that the collection box 21 can collect the material.

[0039] When the material in the hopper 4 is blocked, the first motor 519 drives the rotating shaft 517 and the gear 518 to rotate, so that the gear 518 can drive the lifting plate 512, the fixing rod 513 and the pressing plate 511 to move downward through the rack plate 515, so that the pressing plate 511 can press the material in the hopper 4, so that the blocked material can be pressed out of the hopper 4, so that the material in the hopper 4 can be discharged normally.

[0040] When the classifier body 1 is screening and grading the material, the screened material can fall into the collecting box 21. When the collecting box 21 is full of material, the pulling plate 25 drives the collecting box 21 and the slider 22 to move, so that the slider 22 can squeeze the second spring 24, so that the collecting box 21 can be pulled out of the classifier body 1, so that the staff can easily process the material inside the collecting box 21. When the staff does not pull the collecting box 21, the elastic force of the second spring 24 can drive the collecting box 21 to be retracted into the classifier body 1, so that the collecting box 21 can collect the material.
