Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a vibrating screen with an adjustable feed inlet diameter. Background Technology

[0002] Vibrating screens are key equipment for material grading and screening, widely used in mining, chemical, grain processing, building materials, coal and other industrial fields. Their core is to drive the screen body to generate periodic vibration through vibration sources such as motors and vibrators, so that the bulk materials to be processed will loosen, jump or translate on the inclined or horizontal screen surface equipped with screens of different aperture sizes. Most existing vibrating screens use a fixed aperture design for the feed inlet. When processing large-particle materials, the fixed small aperture can easily cause material to accumulate and block the feed inlet, requiring the machine to be stopped for manual cleaning. This not only interrupts the production process but also increases the intensity of manual labor. When processing small-particle materials, the fixed large aperture will cause the material to rush into the screen surface too quickly, and some fine materials will be discharged with the coarse materials without being fully screened, resulting in material waste. Therefore, this utility model provides a vibrating screen with an adjustable feed inlet diameter. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a vibrating screen with an adjustable feed inlet diameter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vibrating screen with an adjustable feed inlet diameter, comprising a vibrating screen machine and an adjustment component, the adjustment component comprising a feed frame fixedly connected to the vibrating screen machine, a sliding plate one slidably connected to the outer side of the feed frame, a sliding plate two slidably connected to the outer side of the feed frame, an extension bending plate fixedly connected to the outer side of the sliding plate one, a top rod fixedly connected to the outer side of the sliding plate two, and a bottom rod fixedly connected to the outer side of the extension bending plate; The drive assembly includes a gear rotatably connected to the feed frame, a second tooth fixedly connected to the top of the first slide plate, and a first tooth fixedly connected to the bottom of the second slide plate.

[0005] In a preferred embodiment, both tooth one and tooth two are meshed with gears.

[0006] In a preferred embodiment, a first limiting plate is fixedly connected to the outer side of the feeding frame, and a second limiting plate is fixedly connected to the outer side of the feeding frame.

[0007] In a preferred embodiment, the outer side of the top rod is slidably connected to the first limiting plate, and the outer side of the bottom rod is slidably connected to the second limiting plate.

[0008] In a preferred embodiment, the top rod and the bottom rod are slidably connected to the inner wall of the feed frame on their outer sides.

[0009] In a preferred embodiment, the outer side of the extended bending plate is slidably connected to the inner wall of the feed frame.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention uses gears to simultaneously drive tooth one and tooth two, which in turn drives slide plate one and slide plate two to open and close symmetrically at the same speed. This causes the top rod and bottom rod to slide linearly along the four points of limiting plate one and limiting plate two, ultimately causing the width of the feed inlet to expand or shrink instantaneously. This design allows for adjustment of the feed inlet size without stopping the machine. It effectively solves the problems of easy clogging when the fixed aperture is used for large particles and rapid waste when using small particles. It allows for on-site enlargement of the opening to prevent clogging of large particles and immediate reduction of the opening to limit the flow of small particles, completely eliminating the need for manual unblocking and secondary screening during machine shutdown. This results in continuous production, improved screening efficiency, and reduced material waste. Attached Figure Description

[0013] 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.

[0014] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a vibrating screen with an adjustable feed inlet diameter, including a vibrating screen machine 1 and an adjusting component 2. The adjusting component 2 includes a feed frame 21 fixedly connected to the vibrating screen machine 1. A sliding plate 22 is slidably connected to the outer side of the feed frame 21, and a sliding plate 23 is slidably connected to the outer side of the feed frame 21. An extension bending plate 24 is fixedly connected to the outer side of the sliding plate 22, and a top rod 25 is fixedly connected to the outer side of the sliding plate 23. A bottom rod 26 is fixedly connected to the outer side of the extension bending plate 24. A limiting plate 27 and a limiting plate 28 are fixedly connected to the outer side of the feed frame 21. The outer side of the top rod 25 is slidably connected to the limiting plate 27, and the outer side of the bottom rod 26 is slidably connected to the limiting plate 28. The outer sides of the top rod 25 and the bottom rod 26 are slidably connected to the inner wall of the feed frame 21, and the outer side of the extension bending plate 24 is slidably connected to the inner wall of the feed frame 21. The feed frame 21 is a connecting carrier: fixed on the vibrating screen 1, providing a mounting base for components such as slide plate 1 22, slide plate 23, and limiting plate. Slide plate 1 22 and slide plate 23 cooperate, changing their overlapping area within the feed frame 21 through lateral sliding, directly controlling the effective aperture size of the feed inlet. Slide plate 23 and slide plate 1 22 have a "symmetrical sliding" relationship, jointly forming the "two-sided adjustment edges" of the feed inlet. The aperture is enlarged and reduced by reverse sliding. The extension bending plate 24 extends the adjustment stroke of slide plate 1 22: fixed on the outside of slide plate 1 22, sliding synchronously with slide plate 1 22, filling the gap after slide plate 1 22 slides. The top rod 25 connects to the fixed... Position: Fixed on the outside of slide plate 23, one end is slidably connected to limit plate 27, and the other end is slidably embedded in the inner wall of feed frame 21. Bottom rod 26 synchronous guide: Fixed on the outside of extension bending plate 24, one end is slidably connected to limit plate 28, and the other end is embedded in the inner wall of feed frame 21. Linkage support: Slides synchronously with extension bending plate 24, driving slide plate 22 to maintain stable stroke. Limit plate 27 is fixed on the outside of feed frame 21, providing a "sliding track" for top rod 25, while limiting the maximum sliding stroke of top rod 25. Limit plate 28 is fixed on the outside of feed frame 21, providing a sliding track for bottom rod 26, while limiting the maximum stroke of bottom rod 26. The drive assembly 3 includes a gear 33 rotatably connected to the feed frame 21, a tooth 32 fixedly connected to the top of the slide plate 22, and a tooth 31 fixedly connected to the bottom of the slide plate 23. Both the tooth 31 and the tooth 32 are meshed with the gear 33.

[0015] Tooth 31 is fixed to the bottom end of slide plate 23 and meshes with gear 33, converting the rotational motion of gear 33 into the lateral linear motion of slide plate 23. Tooth 32 is fixed to the top end of slide plate 22 and meshes with gear 33 (located on both sides of gear 33, respectively with tooth 31), converting the rotational motion of gear 33 into the opposite lateral linear motion of slide plate 22. Gear 33 is rotatably connected to feed frame 21, serving as an intermediate transmission hub, and simultaneously meshes tooth 31 and tooth 32 to transmit power and change the direction of motion.

[0016] Working principle: like Figure 1 - Figure 5 As shown: In use: First, the external power drives the gear 33 to rotate clockwise / counterclockwise around its rotation center fixed on the feed frame 21. Then, the gear 33 simultaneously engages with teeth 31 and 32 located on its upper and lower sides, converting its rotational motion into two opposing linear motions—tooth 31 slides to the left with slide plate 23, and tooth 32 slides to the right with slide plate 22. This causes slide plate 23 and slide plate 22 to slide laterally in opposite directions at the same speed, thus fixing the slide plate 21 to the feed frame 21. The top rod 25 on the outer side of plate 23 slides in the same direction along the inner hole of limiting plate 1 27, and the bottom rod 26 fixed on the outer side of the extension bending plate 24 slides in the opposite direction along the inner hole of limiting plate 28. The two rods form a four-point linear guide in the corresponding grooves on the inner wall of the feed frame 21, which can drive the slide plate 1 22, the extension bending plate 24, and the slide plate 23 to maintain a stable linear motion without tilting or shaking. Finally, the width of the notch formed by the relative edges of slide plate 1 22 and slide plate 23 is expanded or reduced synchronously.

[0017] 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.
