Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a multi-stage vibrating screen structure for material sorting. Background Technology

[0002] Material sorting refers to the process of separating different components in a mixture into single or similar components based on the differences in their physical and chemical properties (such as density, particle size, magnetism, conductivity, color, surface wettability, etc.) using specific technologies or equipment.

[0003] Vibrating screen separators, as core equipment in the field of material sorting, are widely used in industries such as mining, chemical raw material processing, building materials processing, and food processing. They drive materials to stratify and pass through the screen surface through high-frequency vibration, achieving efficient separation of materials of different particle sizes or densities. However, most of the screens in current mainstream vibrating screen separators adopt a fixed aperture design, and the mesh size needs to be customized according to the initial design requirements of the target material. When the production scenario changes (such as processing different batches of materials, adjusting the sorting accuracy, or switching product specifications), traditional equipment cannot replace the screen through simple operations. Moreover, because vibrating screen separators are usually large in size, the screen replacement operation is more cumbersome and complicated, resulting in low screen replacement efficiency and insufficient flexibility in use. Utility Model Content

[0004] The purpose of this invention is to address the problem that in the existing technology, most mainstream vibrating screen separators use a fixed aperture design for their screens, and the mesh size needs to be customized according to the initial design requirements of the target material. When the production scenario changes (such as processing different batches of materials, adjusting the sorting accuracy, or switching product specifications), traditional equipment cannot replace the screen through simple operations. Furthermore, since vibrating screen separators are usually large in size, the screen replacement operation is more cumbersome and complicated, resulting in low screen replacement efficiency and insufficient flexibility in the use of vibrating screen separators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage vibrating screen structure for material sorting, including a housing, a vibrating motor fixedly connected to the side wall of the housing, two connecting frames fixedly connected inside the housing, a filter frame provided in the connecting frame, and a quick-connecting mechanism provided between the filter frame and the connecting frame for movable connection.

[0006] The quick connection mechanism includes: a locking block fixedly connected to both ends of the filter frame; a locking groove provided at the corresponding locking block of the connecting frame; a limiting slider slidably connected at the corresponding locking groove of the connecting frame; an installation block fixedly connected to the connecting frame at the limiting slider; a threaded pin rotatably connected inside the installation block; the threaded pin is threadedly connected to the limiting slider; and a positioning plate fixedly connected to the connecting frame on the other side of the installation block.

[0007] In the synchronous drive mechanism, all the threaded pins in the same vertical direction are connected to the synchronous drive mechanism for transmission.

[0008] In a preferred embodiment, the synchronous drive mechanism includes a mounting bracket fixedly connected to the inner wall, and a rotating shaft rotatably connected between multiple mounting brackets in the same vertical direction. A first bevel gear is fixedly connected to the rotating shaft at a threaded pin, and a second bevel gear is fixedly connected to the end of the threaded pin. The first bevel gear and the second bevel gear mesh and drive each other.

[0009] In a preferred embodiment, a baffle is fixedly connected to the top side of the filter frame to prevent material from deviating.

[0010] In a preferred embodiment, the outer center of the baffle is provided with a buckle groove, which makes it easy to pull up the baffle when replacing the filter frame.

[0011] In a preferred embodiment, a torsion handle is fixedly connected to the top of the rotating shaft. The outer circumference of the torsion handle is uniformly provided with grooves. The torsion handle facilitates the driving of the rotating shaft, and the grooves can improve the contact friction of the rotating shaft, making it easier to rotate the rotating shaft.

[0012] In a preferred embodiment, the housing is provided with a first discharge channel and a second discharge channel at the height of the connecting frame. The output directions of the first discharge channel and the second discharge channel are staggered to facilitate the separate output of materials.

[0013] In a preferred embodiment, a base plate is fixedly connected to the bottom of the housing to facilitate the output of materials passing through the second connecting frame.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention enables the unlocking or limiting of multiple filter frames. The unlocking control is achieved by rotating the torsion handle, thus enabling quick replacement of the filter frames. The operation is simple and fast, the replacement efficiency is high, and the flexibility of the device can be improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a multi-stage vibrating screen structure for material sorting, including a housing 1, a vibrating motor 2 fixedly connected to the side wall of the housing 1, two connecting frames 3 fixedly connected inside the housing 1, a filter frame 4 set inside the connecting frames 3, and a quick-connecting mechanism movably connecting the filter frame 4 to the connecting frames 3. The filter frame 4 needs to be equipped with a replacement part, and the size of its internal filter holes is designed according to the product to facilitate timely replacement.

[0024] The quick-connect mechanism includes: a locking block 19 fixedly connected to both ends of the filter frame 4; a locking groove 18 provided at the corresponding position of the locking block 19 on the connecting frame 3; a limiting slider 12 slidably connected at the corresponding position of the locking groove 18 on the connecting frame 3; an installation block 14 fixedly connected at the limiting slider 12 on the connecting frame 3; a threaded pin 15 rotatably connected inside the installation block 14; the threaded pin 15 is threadedly connected to the limiting slider 12; and a positioning plate 13 fixedly connected on the other side of the installation block 14 on the connecting frame 3. The positioning plate 13 is used for limiting the movement of the limiting slider 12 and prevents it from rotating out of the threaded pin 15. By rotating the threaded pin 15, the limiting slider 12 can be driven to move. With the locking block 19 of the connecting frame 3 and the locking groove 18 on the connecting frame 3, after the locking block 19 is placed into the locking groove 18, the limiting slider 12 can be placed above the locking groove 18 by the threaded pin 15, thereby fixing and limiting the locking block 19.

[0025] The synchronous drive mechanism has threaded pins 15 connected to the synchronous drive mechanism in the same vertical direction. By setting the synchronous drive mechanism, multiple limit sliders 12 can be driven synchronously.

[0026] like Figure 1-4 As shown, the synchronous drive mechanism includes a mounting bracket 9 fixedly connected to the inner wall. Multiple mounting brackets 9 in the same vertical direction are rotatably connected to a rotating shaft 10. A first bevel gear 16 is fixedly connected to the rotating shaft 10 at the threaded pin 15. A second bevel gear 17 is fixedly connected to the end of the threaded pin 15. The first bevel gear 16 and the second bevel gear 17 are meshed and connected for transmission. By rotating the rotating shaft 10 in coordination with the first bevel gear 16 and the second bevel gear 17, the threaded pin 15 in the same vertical direction can be driven to rotate synchronously. The operation is simple and quick, and the function of quickly unlocking the card block 19 can be realized.

[0027] like Figure 1-4 As shown, a baffle 5 is fixedly connected to the top side of the filter frame 4. By setting the baffle 5, the material can be prevented from running off-center.

[0028] like Figure 1-4 As shown, the outer center of the baffle 5 is provided with a buckle groove 20. The buckle groove 20 makes it easy to pull up the baffle 5 when replacing it, so as to facilitate the replacement of the filter frame 4.

[0029] like Figure 1-4 As shown, a torsion handle 11 is fixedly connected to the top of the rotating shaft 10. The outer circumference of the torsion handle 11 is uniformly provided with grooves. The torsion handle 11 facilitates the driving of the rotating shaft 10, and the grooves can improve the contact friction of the rotating shaft 10, making it easier to rotate the rotating shaft 10.

[0030] like Figure 1-4 As shown, the housing 1 is provided with a first discharge channel 6 and a second discharge channel 7 at the height of the connecting frame 3. The output directions of the first discharge channel 6 and the second discharge channel 7 are staggered to facilitate the output of materials from different sides.

[0031] like Figure 1-4 As shown, a base plate 8 is fixedly connected to the bottom of the casing 1, which facilitates the output of materials passing through the second connecting frame 3.

[0032] Working principle: When replacing the filter frame 4, the rotating shaft 10 is driven to rotate by rotating the torsion handle 11. The first bevel gear 16 at different heights on the rotating shaft 10 drives the second bevel gear 17 at the end of the threaded pin 15 at the corresponding height, thereby driving multiple limit sliders 12 to slide away from the locking block 19, thus unlocking multiple locking blocks 19. Then, the filter frame 4 can be replaced through the locking groove 20. After the replacement is completed, the torsion handle 11 is turned back to complete the fixing operation. The replacement operation of the filter frame 4 is simple and quick, with high replacement efficiency, which can improve the flexibility of the device.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
