Description

Technical Field

[0001] This utility model relates to the field of vibrating feeder technology, specifically a multi-angle vibrating feeder. Background Technology

[0002] Vibrating feeders are indispensable general-purpose feeding equipment in industries such as metallurgy, mining, chemical industry, and building materials. Their core function is to quantitatively, uniformly, and continuously transport lumpy, granular, or powdery materials from storage bins to receiving devices. In actual production, due to the different physical characteristics of the materials being processed (such as particle size, moisture content, and friction angle) and process requirements, it is often necessary to adjust the feeding speed and throughput of the feeder.

[0003] Currently, the most common method for adjusting the feeding capacity of a vibrating feeder is to change the inclination angle of the feeding trough. Increasing the inclination angle increases the component of the material's force in the direction of gravity, increasing the flow velocity and throughput; conversely, decreasing the inclination angle slows the flow velocity. A common method is the shim method, which involves placing steel plates or modules of different thicknesses under the feeder base to change the height of one end. This method is extremely inconvenient, requiring machine shutdown and the use of lifting equipment, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multi-angle vibrating feeder that can quickly find the optimal working angle for different materials, optimize processing capacity, is easy to adjust, simple to operate, and does not require machine shutdown or other equipment, thus greatly improving work efficiency and effectively solving the problems in the background art.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a multi-angle vibrating feeder, including a vibrating feeder body 1. A mounting bracket 10 is connected to the lower surface of the vibrating feeder body 1 away from the discharge port via a vibration spring 12. A vibrator 11 is mounted on the lower surface of the mounting bracket 10. All connecting bolts in this vibrating feeder, especially the bolts mounting the vibrator 11 and the vibration spring 12, are designed with anti-loosening features such as spring washers or lock nuts.

[0017] The lower surface of the vibrating feeder body 1, near the discharge port, is connected to the rotating block A3 via a connecting column 4. Rotating shafts A are fixedly mounted at both ends of the rotating block A3. The rotating shafts A rotate within grooves formed on the side surface of the fixed frame 2, and bearings matching the rotating shafts A are installed within these grooves. Through the rotating shafts A and the bearings, the vibrating feeder body 1 can tilt and rotate, adjusting the angle of its discharge port and thus regulating the discharge speed.

[0018] A base 6 is placed on the side of the fixed frame 2. A groove is formed on the upper surface of the base 6, and a sliding frame 7 is slidably mounted within the groove. A lifting frame 8 is slidably mounted on the upper surface of the sliding frame 7. The upper surface of the sliding frame 7 and the lower surface of the lifting frame 8 are corresponding inclined surfaces. The inclined surface of the sliding frame 7 is oriented downwards towards the discharge port of the vibrating feeder body 1, and the inclined surface of the lifting frame 8 matches it. When the sliding frame 7 slides back and forth, it can drive the lifting frame 8 to move up and down. A groove is formed on the upper side surface of the lifting frame 8, and a rotating shaft B is rotatably mounted within the groove. A bearing matching the rotating shaft B is also installed within the groove. A rotating block B9 is fixedly mounted on the outside of the rotating shaft B. The upper surface of the rotating block B9 is fixedly connected to the lower surface of the mounting frame 10. Simultaneously, the lifting frame 8 can drive the rotating block B9, the mounting frame 10, and the vibrating feeder body 1 to move up and down. Combined with the rotation of the rotating block A3, the overall angle of the vibrating feeder body 1 can be adjusted, thereby adjusting the tilt angle of its discharge port and the discharge speed. The entire adjustment mechanism is integrated within the original support space of the equipment. During the adjustment process, the total length, total width of the feeder and the position of the installation foundation remain unchanged, making it suitable for situations with compact space layout or where the installation foundation is already fixed.

[0019] Self-aligning roller bearings capable of withstanding axial and radial loads are selected to absorb vibration and installation errors. Additionally, rubber buffer pads are added at the connection points between the lifting frame 8 and the rotating block B9, and between the fixed frame 2 and the rotating block A3, to partially isolate and attenuate high-frequency vibrations transmitted to the adjustment mechanism.

[0020] In a preferred embodiment, a hydraulic cylinder 13 is mounted on the outer surface of the base 6. The movable end of the hydraulic cylinder 13 passes into the placement groove and contacts the side surface of the sliding frame 7. The operator can easily and effortlessly remotely adjust the tilt angle by controlling the hydraulic system, significantly reducing labor intensity. This also lays the foundation for integrating this function into a central automated control system and realizing intelligent real-time adjustment based on process parameters. Two or more hydraulic cylinders 13 can be selected. When multiple hydraulic cylinders 13 are used, a synchronization valve is installed in the oil circuit leading to each hydraulic cylinder 13. This valve has a special throttling orifice and pressure compensation mechanism, which can distribute the oil output from the pump equally to the two hydraulic cylinders (when extended), or collect the return oil from the two hydraulic cylinders equally back to the oil tank (when retracted), thereby achieving flow synchronization and extension synchronization.

[0021] In a preferred embodiment, the movable end face of the hydraulic cylinder 13 is provided with a buffer pad 14. When the hydraulic cylinder 13 pushes the sliding frame 7 to reciprocate, at the moment of starting and stopping, and when the vibration generated by the continuous operation of the vibrating feeder is transmitted back to the hydraulic cylinder 13 through the sliding frame 7, the buffer pad 14 can play a buffering and vibration isolation role, avoiding hard impact and wear between metal parts. This not only makes the operation more stable and quiet, but also greatly reduces the fatigue damage of parts caused by impact and vibration, thereby improving the reliability and durability of the system.

[0022] Replaceable wear-resistant liners (such as those made of high-molecular-weight polyethylene or copper-based alloy) are provided between the placement slots of the sliding frame 7 and the base 6, and between the mating inclined surfaces of the sliding frame 7 and the lifting frame 8. Meanwhile, lubrication lines and grease fittings are provided on the sliding frame 7 and / or the lifting frame 8 to facilitate regular grease application, thereby reducing frictional resistance, minimizing wear, ensuring smooth adjustment, and extending service life.

[0023] Optionally, at least one vertical slide is provided on the inner surface of the placement groove, and corresponding slide bars are fixedly provided on both sides of the lifting frame 8. The slide bars slide up and down in the slide groove to limit the lifting frame 8 and prevent it from sliding back and forth along the discharge direction of the vibrating feeder.

[0024] An optional technical solution involves providing grooves 15 on the outer surfaces of the two side plates near the discharge port on the main body 1 of the vibrating feeder. Sliding blocks are slidably mounted within these grooves 15, and U-shaped extension plates 16 are fixedly mounted on the outer sides of the two sliding blocks. These extension plates 16 are slidably mounted on the outer side of the vibrating feeder main body 1 near the discharge port via the sliding blocks. When the feeder's tilt angle is adjusted, the height and horizontal position of the discharge port change accordingly, potentially creating gaps with fixed downstream equipment (such as belt conveyors). By using the slidable U-shaped extension plates 16, after adjusting the tilt angle, the extension plates 16 can be manually or automatically pushed to ensure that their extended ends always tightly overlap with the downstream equipment, forming a dynamic sealed channel. This guarantees that materials can be transported completely and environmentally friendly at any working angle, improving the overall integrity and cleanliness of the system.

[0025] Optionally, the two side plates of the extension plate 16 are provided with screw holes on their side surfaces, and fixing bolts 17 are threaded into the screw holes. When the extension plate 16 is slid to make it tightly overlap with the downstream receiving equipment, tightening the fixing bolts 17 can use the fastening force generated between the bolt end and the side plate of the vibrating feeder to firmly lock the extension plate 16 onto the side plate of the vibrating feeder body 1. This avoids the problem that the extension plate 16 may slip and leave the optimal discharge position during operation, thereby ensuring that the discharge interface of the feeder can be kept in the appropriate position under different inclination angles, and improving the operational reliability of the equipment.

[0026] Furthermore, handles 18 are fixedly provided on the upper surface of the two side plates of the extension plate 16. When it is necessary to adjust the position of the extension plate 16 according to the change of tilt angle, the operator can easily and steadily push and pull the extension plate 16 through the handles 18. The operation is simple and the adjustment is convenient, which further improves the work efficiency.

[0027] In a preferred embodiment, a plurality of positioning pin holes 19 are evenly provided on the side surfaces of the fixed frame 2, the rotating shaft A, the lifting frame 8, and the rotating shaft B. Rigid positioning pins are inserted into the positioning pin holes 19. After the feeder is adjusted to the target tilt angle by the hydraulic cylinder 13, positioning pins are inserted into the corresponding positioning pin holes 19 at key hinge points and sliding pairs such as the fixed frame and rotating shaft A, and the lifting frame and rotating shaft B. This rigidly connects the moving parts and the fixed parts into one, forming a purely mechanical locking guarantee. This ensures that the entire support structure will not experience slight angular drift or settlement when facing strong and continuous working vibrations, further improving the stability of use.

[0028] Optionally, an angle scale can be installed in a prominent position on the fixed frame 2 or the lifting frame 8, and a corresponding pointer can be installed on the rotating block A3 or the rotating block B9. Alternatively, a displacement sensor can be installed on the travel path of the lifting frame 8. By measuring the displacement of the lifting frame 8, the current feeder tilt angle can be indirectly calculated and displayed, providing feedback signals for automated control and thus improving the accuracy of angle adjustment.

[0029] The displacement sensor, hydraulic cylinder 13, and vibrator 11 used in this application are all commonly used electronic components in the prior art. They are powered by an external power source and controlled by an external controller such as a PLC controller or a microcontroller. Their specific structure, working principle, control method, and circuit connection are all well-known technologies and will not be described in detail here.

[0030] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
