Description

Technical Field

[0001] This utility model relates to the field of feeding hopper technology, and in particular to a feeding hopper with a built-in screening component. Background Technology

[0002] Traditional hoppers often face problems such as poor flowability, clumping and blockage, low screening efficiency, and high energy consumption and cost when processing powdery and granular materials, making it difficult to meet the demands of modern industry for high efficiency, environmental protection and intelligence. To address this, the industry has gradually developed hopper technology with built-in screening components. Through mechanical vibration, dynamic screening, multi-stage screening and intelligent control, the discharge efficiency and screening accuracy are significantly improved, while the blockage rate and energy consumption are reduced. A quartz sand discharge hopper, with publication number CN216334905U, includes a quartz sand discharge hopper body. Support columns are welded to the front and rear ends of the outer surfaces at both ends of the quartz sand discharge hopper body. Mounting frames are welded to the lower outer surfaces of four sets of support columns. Vibration damping mechanisms are fixedly connected to the front and rear ends of the upper outer surface of the mounting frames, and mounting mechanisms are fixedly connected to the four corners of the lower outer surface of the mounting frames. This quartz sand discharge hopper, through the use of damping blocks, trapezoidal sealing blocks, and damping springs, reduces the impact of vibration on the mounting mechanism. This reduces the risk of vibration causing screws or bolts to loosen and leading to unstable installation when the mounting mechanism is installed on the corresponding quartz sand production device. The mounting mechanism facilitates the installation of the quartz sand discharge hopper body onto the corresponding quartz sand production device, and this installation structure is easy to dismantle, bringing better application prospects to the field of quartz sand production technology.

[0003] The existing technology described above lacks a screening design during the material feeding process, which can easily cause material blockage when materials of different specifications fall. The discharge hopper is inconvenient to disassemble, which makes it difficult to clear the blockage and increases downtime. Furthermore, the shock absorption mechanism may increase maintenance complexity. Therefore, corresponding improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a discharge hopper with a built-in screening component to solve the problem mentioned in the background art that existing discharge hoppers are prone to material blockage during the discharge process, which affects the discharge efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hopper with an internal screening component, comprising a box body and an inlet. The inlet is connected to the top of the box body. Hinges are connected to both inner walls of the box body, and guide plates are movably connected to one end of each hinge. A return spring is connected to the bottom of each guide plate. A protrusion is provided on the box body, and the protrusion has a triangular cross-section. An inspection door is provided on the outer side of the box body. A screening box is provided inside the box body, and a spring rod is connected to one end of the screening box. An inner hopper is provided at the bottom of the screening box, and a discharge pipe is provided at the bottom of the inner hopper.

[0006] Furthermore, a protrusion is connected to the other end of the screening box, and an eccentric wheel is provided at one end of the protrusion. An internal shaft is connected to the eccentric wheel, and a motor is connected to one end of the shaft. The motor is located on the outside of the box.

[0007] Furthermore, guide blocks are connected to both sides of the screening box, and guide columns are slidably connected inside the guide blocks. The two ends of the guide columns are fixed to the inner wall of the box, and a screen is connected to the bottom of the screening box.

[0008] Furthermore, each of the inner hoppers has a docking hole at its bottom, and an arc-shaped groove is formed on both inner walls of the docking hole.

[0009] Furthermore, a valve plug is provided on the outside of the discharge pipe, a sealing plate is sleeved on the discharge pipe, a connecting plate is sleeved on one end of the discharge pipe, and a fixing block is connected to both ends of the connecting plate, and a semi-circular protrusion is connected to both sides of the fixing block.

[0010] Furthermore, the arc-shaped grooves on both sides of the docking hole engage with the semi-circular protrusions on both sides of the fixing block.

[0011] Furthermore, the area of ​​the top cross-section of the inner hopper is greater than the cross-sectional area of ​​the screen box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the discharge hopper with the built-in screening component not only realizes the accurate screening of materials and avoids large materials from clogging the feed port, but also buffers the materials when they are fed in, preventing the materials from damaging the inner wall of the discharge hopper. By starting the motor, the machine shaft drives the eccentric wheel to rotate. One end of the eccentric wheel rotates and strikes the protrusion, which causes the screen box to vibrate. The spring rod at one end of the screen box also moves left and right, thereby screening the material inside the screen box. Foreign objects are intercepted by the screen at the bottom of the screen box, improving the purity of the material. The vibration design can keep the material flow unobstructed and reduce the risk of blockage. The hinged seat, guide plate, and return spring provide a certain buffer when the material enters the box. Slow feeding can prevent large-volume or lumpy materials from clogging due to rapid accumulation, ensuring the screening process is continuous and reducing mechanical wear on the equipment. By forcefully pulling the discharge pipe, the discharge pipe can be extracted from the inner hopper. The discharge pipe can be cleaned separately. During installation, simply push it to install the discharge pipe onto the inner hopper. The fixing blocks at both ends of the connecting plate on the discharge pipe are fixed in the docking holes set inside the inner hopper. The semi-circular protrusions on both sides of the fixing blocks are fixed in the arc-shaped grooves at both ends of the docking holes for a more secure fit. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-5 An embodiment of this utility model is provided: a feeding hopper with a built-in screening component, including a box body 1 and a feeding port 2. The feeding port 2 is connected to the top of the box body 1. Hinges 3 are connected to both inner walls of the box body 1, and guide plates 4 are movably connected to one end of each hinge 3. Return springs 5 ​​are connected to the bottom of each guide plate 4. A protrusion is provided on the box body 1, and the cross-section of the protrusion is triangular. An inspection door is provided on the outer side of the box body 1. Specifically, such as Figure 1 and Figure 2 As shown, during use, when the material falls onto the guide plate 4, the hinge seat 3 and the guide plate 4 are movably connected. The return spring 5 at the bottom of the guide plate 4 can absorb the energy generated when the material impacts the guide plate 4, reducing the direct collision between the material and the guide plate 4, and preventing the material from directly impacting the screen box 6. The triangular protrusions on the inner wall are to prevent the material from leaking out and falling from the side. If small materials fall to the bottom of the box 1, the inspection door can be opened for cleaning. The box 1 is equipped with a screening box 6, and one end of the screening box 6 is connected to a spring rod 9; The other end of the screening box 6 is connected to a protrusion 8, and one end of the protrusion 8 is provided with an eccentric wheel 701. The eccentric wheel 701 is connected to a machine shaft 7, and one end of the machine shaft 7 is connected to a motor 14. The motor 14 is located on the outside of the box 1. Guide blocks 15 are connected to both sides of the screening box 6, and guide columns 16 are slidably connected inside the guide blocks 15. The two ends of the guide columns 16 are fixed to the inner wall of the box body 1, and the bottom end of the screening box 6 is connected to the screen 10. Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, when in use, the motor 14 is started, and the shaft 7 drives the eccentric wheel 701 to rotate. When the eccentric wheel 701 rotates, one end will strike the protrusion 8 on one side of the screen box 6. The vibration of the protrusion 8 will drive the spring rod 9 to move left and right, so that the spring rod 9 is elastically stretched and contracted, which will drive the screen box 6 to move left and right and generate vibration. At the same time, it will drive the guide blocks 15 on both sides of the screen box 6 to move on the guide column 16. The rigid structure of the guide column 16 can effectively resist the deflection or tilt of the guide block 15, so that the guide block 15 always maintains a straight line movement. For materials with large density differences, vibration can destroy the stratification tendency and maintain the stability of the material. The bottom of the screening box 6 is provided with an inner hopper 11, and the bottom of the inner hopper 11 is provided with a discharge pipe 13. The bottom of the inner hopper 11 is provided with a docking hole 19, and the two inner walls of the docking hole 19 are provided with arc-shaped grooves. A valve plug 12 is provided on the outside of the discharge pipe 13, a sealing plate 20 is sleeved on the discharge pipe 13, a connecting plate 17 is sleeved on one end of the discharge pipe 13, and a fixing block 18 is connected to both ends of the connecting plate 17, and a semi-circular protrusion is connected to both sides of the fixing block 18. The arc-shaped grooves on both sides of the mating hole 19 and the semi-circular protrusions on both sides of the fixing block 18 engage with each other; The area of ​​the top cross-section of the inner hopper 11 is greater than the cross-sectional area of ​​the screen box 6; Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, if the discharge pipe 13 becomes clogged during use, it can be easily pulled out of the inner hopper 11 by force and repaired. After cleaning, the discharge pipe 13 can be fixed in the inner hopper 11 by simply pushing it to fix the fixing block 18 on the docking hole 19. The circular protrusions on both sides of the fixing block 18 are fixed in the arc grooves on both sides of the docking hole 19, which serves to tighten it. The discharge pipe 13 can be easily replaced without disassembling the entire equipment.

[0018] Working principle: When using this utility model, firstly, the material is poured into the inside of the box 1 from the feed port 2. The guide plates 4 on both sides of the inside of the box 1 buffer the material. When the material falls onto the guide plate 4, the hinge seat 3 is movably connected to the guide plate 4. The return spring 5 at the bottom of the guide plate 4 can absorb the energy generated when the material impacts the guide plate 4, reducing the direct collision between the material and the guide plate 4, avoiding the material from directly impacting the screen box 6, and reducing the risk of deformation and damage to the screen 10 caused by the impact force. Secondly, after buffering, the material falls into the screening box 6. The motor 14 is started, and the machine shaft 7 drives the eccentric wheel 701 to rotate. When the eccentric wheel 701 rotates, one end will hit the protrusion 8 on one side of the screening box 6. The vibration of the protrusion 8 will drive the spring rod 9 to move left and right, so that the spring rod 9 is elastically stretched and contracted, which will drive the screening box 6 to move left and right and generate vibration. At the same time, it will drive the guide blocks 15 on both sides of the screening box 6 to move on the guide column 16. The rigid structure of the guide column 16 can effectively resist the deflection or tilt of the guide block 15, so that the guide block 15 always maintains a straight line movement. The vibration can cause the material to jump on the screen 10, increasing the contact frequency between the material and the screen 10 and the probability of passing through the screen, thus accelerating the screening. Finally, the screened material falls into the inner hopper 11 and drops from the discharge pipe 13. If the discharge pipe 13 is accidentally blocked, it can be pulled out of the inner hopper 11 by force and repaired. After cleaning, the discharge pipe 13 can be fixed in the inner hopper 11 by force. The fixing block 18 can be fixed on the docking hole 19 by force. The circular protrusions on both sides of the fixing block 18 are fixed in the arc grooves on both sides of the docking hole 19 to play a fastening role. The sealing plate 20 on the discharge pipe 13 can seal the inside of the box 1.
