Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and in particular to a vibrating feeder for screening out crushed materials. Background Technology

[0002] Material screening is a process in which the incoming materials are screened during the production process to remove unqualified materials and transport the materials that meet the production requirements to the next process. Among them, the screening machine is a common piece of equipment in material screening production. When the screening machine is performing screening work, the material is fed in from the inlet, and after the material is screened in the sorting chamber, the good material and the bad material are finally discharged from the outlet.

[0003] Screening machines only require changing different screens when screening different types of crushed materials. However, current screening machines are inconvenient to disassemble because the screens are made of stainless steel plates with through holes. Bolts are connected to bolt holes on the frame through these through holes for fastening, but disassembly requires removing the entire bolt, which is inconvenient and there is a risk of bolts falling off during installation. Therefore, this application proposes a vibrating feeder for screening crushed materials. Utility Model Content

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a vibrating feeder for screening crushed materials, comprising:

[0022] The support frame 1 serves as the support for the entire structure. It mainly consists of a rectangular frame and four sturdy, durable support legs, which are firmly fixed to the bottom of the rectangular frame, ensuring the stability and load-bearing capacity of the entire device. Two first brackets 2 and two second brackets 5 are carefully installed on the rectangular frame. These brackets not only provide support but also lay the foundation for subsequent equipment installation.

[0023] The first support 2 and the second support 5 have different designs; both are equipped with support springs 4 at their upper ends. These support springs 4 provide the necessary elasticity and flexibility for the hopper 3 during vibration. The hopper 3 is stably positioned above the support springs 4. Because the height of the first support 2 is set greater than the height of the second support 5, the hopper 3 can be tilted above the first support 2 and the second support 5. This design allows the hopper 3 to discharge the material from the screen 9 more smoothly during the screening process, avoiding material accumulation and blockage.

[0024] To further improve screening efficiency and material flowability, vibrating motors 8 are specially installed on the hopper 3. These vibrating motors 8 are firmly fixed to the hopper 3 by the mounting bracket 7. Their operation generates a strong vibration effect, which, together with the elasticity of the support spring 4, allows the hopper 3 to vibrate continuously and evenly during the screening process. This vibration not only helps to disperse and evenly distribute the material, but also improves the screening efficiency of the screen 9.

[0025] The screen assembly is the core component of the entire screening equipment, and its design fully considers practicality and convenience. This screen assembly includes a specially designed placement groove 11, which cleverly extends through the bottom of the hopper 3 and presents a stepped structure. This design not only facilitates the placement and positioning of the screen 9 but also helps the material flow smoothly during the screening process.

[0026] A screen 9 is placed inside the placement trough 11, and a guide frame 10 is fixed at the bottom of the hopper 3, opposite to the placement trough 11, forming a perfect material outlet. This outlet can be connected to corresponding processing equipment, such as for screening wheat. The wheat is discharged from this outlet and vibrated to the processing equipment, which can perform crushing, washing, etc., of the wheat. After the material passes through the screen 9, the fine fragments will pass smoothly through the screen 9 and fall into the guide frame 10, and then be discharged through the guide frame 10, making it convenient for users to place a collection box at the bottom of the support frame 1 for centralized collection.

[0027] To facilitate the installation and removal of the screen 9, four bolts 12 are designed on the hopper 3. These bolts 12 are threaded into the hopper 3, ensuring a secure and reliable connection. Pressure blocks 13 are fitted onto the bolts 12, each with a through-hole allowing the bolts 12 to pass easily through. When it is necessary to fix the screen 9, simply tighten the bolts 12, causing the pressure blocks 13 to firmly press against the screen 9, thus achieving precise positioning of the screen 9. This design is not only simple and easy to implement but also highly effective, ensuring the stability and accuracy of the screen 9 during the screening process.

[0028] More importantly, when the screen 9 needs to be disassembled for cleaning or replacement, it is not necessary to completely remove the bolt 12 as in the traditional method. Simply use a tool to gently turn the bolt 12 to loosen it. Then, the pressure block 13 can be easily rotated so that it is no longer in contact with the screen 9, thus freeing the screen 9 from its limiting position and allowing it to be easily removed. This design greatly avoids the inconvenience of completely removing the bolts in existing technologies, providing users with a more convenient and efficient operating experience.

[0029] In screening operations, the physical properties and screening requirements vary depending on the type of crushed material being screened. Therefore, the discharge rate becomes an important parameter that needs to be flexibly adjusted. To meet this requirement, a limiting mechanism is specially designed on the hopper 3 to precisely control the amount of crushed material fed onto the screen 9.

[0030] The core component of this limiting mechanism is a baffle 6 that can slide freely within the hopper 3. The baffle 6 is simple yet practical in design, effectively blocking or guiding the flow of crushed material into the screen 9. To ensure stable and precise movement of the baffle 6, two cleverly designed slots 14 are provided on the hopper 3. These slots 14 not only provide the necessary space for the movement of the baffle 6 but also ensure the linearity and stability of its movement.

[0031] Two screws 15 are slidably connected within the slot 14, and these screws 15 are securely fixed to the baffle 6. Thus, when the baffle 6 moves, the screws 15 also move accordingly, achieving precise control over the position of the baffle 6. To further secure the position of the baffle 6, nuts 16 are threaded onto the screws 15. These nuts 16 can tightly abut against the outer wall of the hopper 3, ensuring that the baffle 6 can stably remain in any position when needed.

[0032] In actual operation, users can easily adjust the distance between the baffle 6 and the bottom of the hopper 3 simply by loosening the nut 16. This distance adjustment directly determines the flow rate of the crushed material entering the screen 9, so users can flexibly set it according to screening requirements and the characteristics of the crushed material. Once a suitable feed rate is found, users only need to tighten the nut 16 again to ensure that the baffle 6 can maintain a stable position when the vibrating motor 8 is working.

[0033] It is worth mentioning that the vibration of the vibrating motor 8 not only helps to evenly distribute the crushed material and improve screening efficiency, but also can prevent material from clogging in the hopper 3 to a certain extent. When the vibrating motor 8 is working, the vibration it generates can make the crushed material pass through the baffle 6 and the screen 9 more smoothly, thereby ensuring the continuity and stability of the screening process.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
