Description

Technical Field

[0001] This utility model relates to the field of feeder technology, and in particular to a feeder with a high-strength bottom guard plate. Background Technology

[0002] A feeder is a mechanical device used to uniformly, continuously or quantitatively convey materials. It is widely used in industries such as mining, metallurgy, chemical industry, building materials, power, and grain processing.

[0003] Currently, feeders are generally classified into types such as screw feeders, vibrating feeders, and rotary feeders based on their working principles. Among them, vibrating feeders have become the ideal choice for feeding fine sand in the glass industry due to their simple structure, easy maintenance, and controllable flow rate.

[0004] However, since the main component of refined sand is SiO2 (Mohs hardness 7), long-term flow or vibration impact of the refined sand will cause micro-cutting wear on the bottom guard plate of the feeder, especially in areas with high-speed feeding or large drop, which will seriously shorten the service life of the equipment (after the bottom guard plate is damaged, material leakage will occur). Although the strength of the bottom guard plate is enhanced by using high-strength wear-resistant materials (such as high-strength steel) to make the bottom guard plate, wear still exists, and since the bottom guard plate is usually installed in the feeder by welding or other methods, it is difficult to replace the bottom guard plate. Utility Model Content

[0005] The main purpose of this utility model is to provide a feeder with a high-strength bottom guard plate, which addresses the problem of difficult bottom guard plate replacement in related technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A feeder with a high-strength bottom guard plate includes a hopper and a conveying mechanism. The conveying mechanism includes a vibrating frame, a bottom guard plate, and a support frame. The vibrating frame and the bottom guard plate are both located on the support frame, and the bottom guard plate and the vibrating frame are detachably connected.

[0008] Furthermore, the vibration frame is provided with several mounting strips, each mounting strip is provided with several connecting holes, and the bottom guard plate is provided with several fixing holes. Each fixing hole and each connecting hole are coaxially arranged in a one-to-one correspondence, and each fixing hole and each connecting hole are provided with a connecting member for threaded connection between the two.

[0009] Furthermore, each of the aforementioned mounting strips is located at the end of the bottom guard plate furthest from the hopper.

[0010] Furthermore, each of the mounting strips and the bottom protective plate is provided with a buffer pad, and each of the buffer pads is provided with several mating holes.

[0011] Furthermore, the projection surface of each of the buffer pads in the material conveying direction has an "L" shaped structure.

[0012] Furthermore, each of the mounting strips is provided with a number of connecting posts, each of the connecting holes passes through each connecting post, and each of the connecting posts and the mating holes are mated to each other.

[0013] Furthermore, each of the aforementioned mating holes includes a first hole body and a second hole body, with each first hole body corresponding to a hole shaft of each connecting post.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] This utility model mainly includes a conveying mechanism, which mainly includes a vibrating frame and a bottom guard plate. Unlike the traditional fixed connection (such as welding) between the vibrating frame and the bottom guard plate, the technical solution of this utility model adopts a method of detachably connecting the bottom guard plate to the vibrating frame, which ensures that when the bottom guard plate is damaged, it can be directly removed from the vibrating frame for replacement, thus solving the problem of difficult disassembly and replacement of the bottom guard plate from the root.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] like Figure 1 As shown, this embodiment mainly proposes a feeder with a high-strength bottom guard plate, which mainly includes a hopper 1 and a conveying mechanism 2. The hopper 1 serves as an intermediate or relay container between this embodiment and other production equipment in the external production line. Its existence can not only prevent the material from the upstream equipment from directly impacting the conveying mechanism 2, but also gather the material so that the material falls accurately into the conveying mechanism 2.

[0028] The conveying mechanism 2 includes a support frame 23, a conveying structure, and a drive structure for driving the conveying structure to carry out conveying. The conveying structure mainly includes a vibrating frame 21 and a bottom guard plate 22. The conveying structure (vibrating frame 21, bottom guard plate 22) and the unloading hopper 1 are all located on the support frame 23. That is, the support frame 23 serves as the main support carrier in this embodiment, enabling this embodiment to adapt well to the height difference between upstream and downstream equipment in the production line.

[0029] The preferred drive structure in this embodiment mainly includes a drive motor, a drive vibration shaft, and several adjustable counterweights. The drive vibration shaft is linked to the output shaft of the drive motor, and each adjustable counterweight is detachably connected to the drive vibration shaft. That is, the preferred drive structure in this embodiment is a drive structure with adjustable vibration amplitude, so that the conveying mechanism 2 has the function of adjusting the feeding speed. The specific structure and working principle of the drive structure should be determined according to the actual type of drive structure selected, and will not be described in detail in this embodiment.

[0030] The bottom guard plate 22 is detachably connected to the vibrating frame 21, thereby ensuring that when the bottom guard plate 22 is damaged, it can be removed from the vibrating frame 21 and replaced. This changes the connection relationship between the bottom guard plate 22 and the vibrating frame 21 in the traditional feeder, thus fundamentally solving the problem of the difficulty in replacing the traditional bottom guard plate 22.

[0031] In this embodiment, the bottom guard plate 22 is preferably made of high-strength wear-resistant materials such as manganese steel, thereby ensuring the structural strength of the bottom guard plate 22 itself, extending the service life of the bottom guard plate 22, and extending the replacement frequency of the bottom guard plate 22.

[0032] Specifically, such as Figures 2-3 As shown, the vibration frame 21 in this embodiment is provided with a plurality of mounting strips 211. Each mounting strip 211 is preferably fixedly connected to the vibration frame 21 by welding to ensure the connection strength between the two. Each mounting strip 211 is provided with a plurality of connecting holes 2111, and the bottom guard plate 22 is provided with a plurality of fixing holes 221. Each fixing hole 221 and each connecting hole 2111 are coaxially arranged in a one-to-one correspondence, and each fixing hole 221 and each connecting hole 2111 are provided with a connector 3 for threaded connection between the two. That is, the detachable connection between the vibration frame 21 and the bottom guard plate 22 is achieved by the threaded connection of the plurality of connectors 3 between the two, which not only ensures the connection strength, but also facilitates the disassembly, assembly and replacement of the bottom guard plate 22.

[0033] In this embodiment, each connector 3 is preferably a common threaded fastener such as a bolt with a nut, so that a replacement can be quickly found if the connector 3 in this embodiment is lost.

[0034] In this embodiment, the bottom guard plate 22 is preferably inclined on the vibrating frame 21, that is, the horizontal height of the end of the bottom guard plate 22 close to the hopper 1 is higher than the horizontal height of the end of the bottom guard plate 22 away from the hopper 1, so as to guide the material to perform rapid feeding.

[0035] Each mounting strip 211 is located at the end of the bottom guard plate 22 away from the hopper 1, so that each mounting strip 211 can not only support the bottom guard plate 22, but also be shielded by the bottom guard plate 22 to prevent the conveyed fine sand (material) from coming into contact with the mounting strip 211 and causing damage to the mounting strip 211.

[0036] Furthermore, each mounting strip 211 is symmetrically and evenly distributed around the bottom guard plate 22, ensuring that there are support points on both sides of the bottom guard plate 22. This allows the bottom guard plate 22 to bear the force from the conveyed material in a balanced manner, thereby reducing the risk of structural deformation or damage to the bottom guard plate 22 and indirectly improving its strength.

[0037] Preferably, a number of reinforcing ribs should be provided between the mounting strip 211 and the vibration frame 21 to ensure the support stability of the mounting strip 211.

[0038] At the same time, such as Figures 2-5As shown, in this embodiment, each mounting strip 211 and the bottom protective plate 22 are provided with a buffer pad 4. Each buffer pad 4 is provided with a plurality of mating holes 41. Each mating hole 41 is used for each connector 3 to penetrate itself, so as to avoid the presence of the buffer pad 4 from interfering with the connection relationship between the connector 3 and the bottom protective plate 22.

[0039] In this embodiment, the buffer pad 4 is preferably made of wear-resistant elastic material such as rubber. By taking advantage of the characteristic of elastic material that it can absorb vibration energy, the vibration amplitude transmitted to the connection of the connector 3 is reduced, thereby reducing the risk of the connector 3 loosening and improving the connection strength between the bottom guard plate 22 and the vibration frame 21.

[0040] Each buffer pad 4 has an "L" shaped projection surface in the material conveying direction, which enables the buffer pad 4 to prevent direct friction between the vibration frame 21 and the bottom guard plate 22, thus avoiding wear or scratches on the surfaces of both.

[0041] Each mounting strip 211 is provided with several connecting posts 2112, and each connecting post 2112 is matched with a corresponding hole 41. Through this hole-shaft matching, the positional constraint between each buffer pad 4 and the mounting strip 211 is achieved, thereby preventing the buffer pad 4 from shifting when installing the bottom guard plate 22 and effectively ensuring the accuracy of the fit between the buffer pad 4 and the bottom guard plate 22. Each connecting hole 2111 passes through each connecting post 2112, that is, the presence of the connecting post 2112 extends the thread length of the connecting hole 2111, thereby enhancing the connection strength between the connector 3 and the mounting strip 211.

[0042] like Figure 6 As shown, each mating hole 41 in this embodiment includes a first hole body 411 and a second hole body 412. Each first hole body 411 is matched with each connecting post 2112 in a one-to-one hole-shaft fit. The diameter of the second hole body 412 is smaller than the diameter of the first hole body 411. The axial length of the first hole body 411 is equal to or less than the axial length of the connecting post 2112. In this way, after each connecting post 2112 and mating hole 41 are matched with each other, they can also form an abutment relationship, avoiding contact between the connecting post 2112 and the bottom guard plate 22, and ensuring that the buffer pad 4 can fully disperse the force transmitted from the vibration frame 21 to the bottom guard plate 22.
