Description

Technical Field

[0001] This utility model belongs to the field of feeder technology, and in particular relates to a vibrating feeder. Background Technology

[0002] With the continuous acceleration of industrial automation, vibrating feeders, as key equipment that enables continuous and uniform material conveying, are widely used in mining, metallurgy, building materials, chemical and other fields. In the production line, they not only undertake the important task of smoothly conveying block, granular or powdery materials from the storage silo to the subsequent processing equipment, but the stability and uniformity of their feeding also directly affect the efficiency of the entire production process and the quality of the final product. Therefore, the market demand for high-performance vibrating feeders continues to grow.

[0003] However, existing vibrating feeders are prone to imbalances in vibration frequency or amplitude during use, resulting in poor vibration effect of the feeding plate. This not only makes it difficult to effectively prevent transportation blockages caused by the accumulation and adhesion of small particles during transportation, but may also cause excessive noise, affecting the normal operation of the equipment and the operating environment. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating feeder. By setting an impact part, it solves the problem that existing vibrating feeders are prone to vibration frequency or amplitude imbalance during use, resulting in poor vibration effect of the feeding plate. This not only makes it difficult to effectively avoid transportation blockage caused by accumulation and adhesion of small particles during transportation, but also may cause excessive noise, affecting the normal operation of the equipment and the operating environment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vibrating feeder, comprising a trough and further comprising: an elastic part, the elastic part including a feeding component and an elastic component, the feeding component being movably installed in the trough for feeding material; the elastic component being installed between the trough and the feeding component for controlling the vertical amplitude of the feeding component; and an impact part, the impact part including an impact component located above the feeding component and a driving component, the impact component being installed on the inner side wall of the trough; the driving component being installed on the side wall of the trough for driving the impact component to move vertically to contact the feeding component.

[0006] Furthermore, it also includes support legs that are fixedly connected to the bottom of the tank.

[0007] Furthermore, a support is fixedly connected to one end of the top of the trough, and a feed hopper is fixedly connected to the inner wall of the support.

[0008] Furthermore, the impact assembly includes two fixed plates fixedly connected to the inner wall of one side of the tank, spaced apart vertically. An impact rod is slidably connected to the two fixed plates, and an impact hammer is fixedly connected to the bottom of the impact rod. A U-shaped block is provided between the two fixed plates. The outer wall of the middle section of the impact rod is fixedly connected to the closed end of the U-shaped block. Two sliding grooves are mirror-shaped formed at the two free ends of the U-shaped block, and a cylindrical sliding rod is slidably connected between the two sliding grooves. The driving assembly includes a cylindrical rod fixedly connected to the inner wall of one side of the tank, and the cylindrical rod is rotatably connected to one end of the tank plate. Next, a slotted hole is formed on the slotted plate, and the other end of the slotted plate is hinged to a cylindrical sliding rod. The driving component includes a motor fixedly connected to the outside of the slot body. The output shaft of the motor is fixedly connected to a rotating shaft passing through the side wall of the slot body via a coupling. The end of the rotating shaft is fixedly connected to one end of the driving plate, and the other end of the driving plate is fixedly connected to a driving rod slidably connected to the slotted hole. The driving plate is located between the inner wall of the front side of the tilting box and the slotted plate, converting the rotational power of the motor into the linear motion power of the impact assembly, providing continuous driving force for the impact vibration. A U-shaped block is located between two fixed plates, converting the driving power into impact force to achieve vibration of the feeding plate.

[0009] Furthermore, the feeding assembly includes four trapezoidal grooves arranged in a rectangular pattern on the inner walls of both sides of the trough. A feeding plate located below the impact hammer is adapted inside the trough. Four extensions extend from both sides of the feeding plate. The four extensions are located in the four trapezoidal grooves, dividing each trapezoidal groove into upper and lower cavities. The elastic component includes four sliding rods that are vertically fixedly connected to the four trapezoidal grooves. The four sliding rods are slidably connected to the four extensions. Each sliding rod is fitted with a spring located between the top / bottom wall of the trapezoidal groove and the extension. Each trapezoidal groove has two springs, one upper and one lower. The structure of the trapezoidal grooves can prevent the feeding plate from derailing from the track and ensure the stability of the transportation process.

[0010] Furthermore, the upper spring has a smaller elastic force than the lower spring. The spring releases potential energy to reset the feeding plate and generate additional shaking, which enhances the vibration effect, assists in the loosening and transportation of materials, and improves the conveying efficiency.

[0011] This utility model has the following beneficial effects: 1. By incorporating an impact section, after the motor is started, the motor drives the drive rod on the drive plate to rotate via the rotating shaft. The drive rod, in conjunction with the slotted hole, drives the slotted plate to rotate on the cylindrical rod. The slotted plate, in turn, drives the U-shaped block to move through the cooperation of the cylindrical sliding rod and the sliding groove. The U-shaped block then drives the impact hammer on the impact rod to move. During the rotation of the drive rod, the impact hammer impacts the top of the feeding plate, the impact rod resets, the impact rod moves away from the feeding plate, and resets again. Through this cyclical operation, the feeding plate vibrates, thereby completing the transportation of small particles. This effectively avoids transportation blockages caused by accumulation and adhesion of small particles during transportation, ensuring continuous and stable material transportation, reducing the vibration of the feeding plate, and avoiding excessive noise. 2. By incorporating an elastic element, when the impact rod presses against the feeding plate, it causes the feeding plate to move downwards along the trapezoidal groove and slide bar, compressing the lower spring to generate elastic force and simultaneously stretching the upper spring to generate tension. When the impact rod moves away from the feeding plate, under the combined action of the elastic and tension forces of these springs, the feeding plate sways along the trapezoidal groove and slide bar, thereby accelerating the transport speed and providing additional power for material transport. This effectively speeds up the transport process of small particles, reduces material retention on the feeding plate, and further ensures smooth transport.

[0016] 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.

[0017] Please see Figure 1-6 As shown, this utility model is a vibrating feeder, including a trough 111, a support leg 112 fixed to the bottom of the trough; a bracket 113 fixed to one end of the top of the trough; and a feed hopper 114 fixed to the top of the bracket. It also includes: an elastic part 3, comprising a feeding component 31 and an elastic component 32, wherein the feeding component is movably installed in the trough for feeding material; the elastic component is installed between the trough and the feeding component for controlling the vertical amplitude of the feeding component; and an impact part 2, comprising an impact component 21 located above the feeding component and a driving component 22, wherein the impact component is installed on the inner side wall of the trough; and the driving component is installed on the side wall of the trough for driving the impact component to move up and down to contact the feeding component. The trough 111, support leg 112, bracket 113, and feed hopper 114 can be referred to as the feeding part 1.

[0018] The impact assembly 21 includes two fixed plates 211 fixedly connected to the inner wall of one side of the groove 111, spaced apart vertically. An impact rod 212 is slidably connected to the two fixed plates 211. An impact hammer 213 is fixedly connected to the bottom of the impact rod 212. A U-shaped block 214 is provided between the two fixed plates. The outer wall of the middle section of the impact rod 212 is fixedly connected to the closed end of the U-shaped block 214. Two sliding grooves 215 are mirror-shaped on the two free ends of the U-shaped block 214. A cylindrical sliding rod 216 is slidably connected between the two sliding grooves 215. The shape of the sliding groove allows the cylindrical sliding rod to slide within a range that supports vertical movement. Lubricating oil can be coated inside the sliding groove to reduce friction. The drive assembly 22 includes a cylindrical rod 221 fixedly connected to the inner wall of one side of the groove 111. The cylindrical rod 221 is rotatably connected to one end of the groove plate 222. The groove plate 222 has a groove hole 223. The groove hole is a curved groove that takes into account the motion trajectory and allows the drive rod to generate push and pull forces when sliding. The other end of the grooved plate 222 is hinged to the cylindrical slide rod 216. The driving component includes a motor 224 fixedly connected to the outside of the groove body 111. The output shaft of the motor 224 is fixedly connected to a rotating shaft 225 passing through the side wall of the groove body via a coupling. The end of the rotating shaft 225 is fixedly connected to one end of the driving plate 226, and the other end of the driving plate 226 is fixedly connected to a driving rod 227 that slidably connects to the grooved hole. By setting the impact part 2, the transportation blockage caused by the accumulation and adhesion of small particles during transportation can be effectively avoided, ensuring continuous and stable material transportation. The impact hammer can be made of rubber or other elastic materials to avoid excessive noise. The diameter of the driving rod 227 must match the width of the grooved hole 223 (to avoid radial sway), and the length of the grooved hole must accommodate the sliding distance of the driving rod 227 at its extreme position. Preferably, the slotted hole adopts an Archimedean spiral or a modified eccentric arc, and its contour needs to meet the following requirements: 0°~90° range: rapid increase in displacement to achieve efficient impact; 90°~270° range: smooth transition to ensure stable reset; closure continuity: seamless connection to the next cycle at 360°.

[0019] The feeding assembly 31 includes four rectangular trapezoidal grooves 311 respectively formed on the inner walls of both sides of the trough 111. A feeding plate 312 located below the impact hammer is fitted inside the trough 111. Four extensions extend from both sides of the feeding plate 312, and these extensions divide each trapezoidal groove 311 into upper and lower cavities. The elastic assembly 32 includes four sliding rods 321 vertically fixedly connected to the four trapezoidal grooves 311. The four sliding rods 321 are slidably connected to the four extensions, and each sliding rod 321 is fitted with a sleeve... A spring 322 is provided between the top / bottom wall of the trapezoidal chute and the extension. Each trapezoidal chute 311 has two springs 322, one upper and one lower. The two ends of the upper spring are connected between the top wall of the trapezoidal chute and the extension, and the two ends of the lower spring are connected between the bottom wall of the trapezoidal chute and the extension. The elastic force of the upper spring 322 is less than that of the lower spring 322. By providing the elastic part 3, additional power is provided for material transportation, which effectively speeds up the transportation process of small particles and reduces the retention of materials on the feeding plate 312, further ensuring the smoothness of transportation.

[0020] A specific application of this embodiment is as follows: During use, small granular materials are added to the trough 111 through the feed hopper 114 and fall onto the top of the feeding plate 312. Then, the motor 224 is started. At this time, the motor 224 drives the drive rod 227 on the drive plate 226 to move counterclockwise by 90 degrees via the rotating shaft 225. Simultaneously, the drive plate 226, through the action of the drive rod 227 and the slotted hole 223, drives the slotted plate 222 to rotate on the cylindrical rod 221. The slotted plate 222, through the cylindrical sliding rod 216 and two sliding grooves 215, drives the U-shaped block 214 to move. The U-shaped block 214 then drives the impact hammer 213 on the impact rod 212 to impact the top of the feeding plate 312. When the drive plate 226 drives the drive rod 227 to move 180 degrees, the impact rod 212 resets. When the rotation reaches 27 degrees... At 0 degrees, the impact rod 212 moves away from the feeding plate 312. When it rotates 360 degrees, the impact rod 212 returns to its original position. Through the above operation, the feeding plate 312 is impacted and vibrated, thus transporting small particles of material. During the above process, the impact rod 212 will squeeze the feeding plate 312, causing the feeding plate 312 to move downward on the four trapezoidal grooves 311 and the four sliding rods 321, and squeeze the four springs 322 located below, generating elastic force. The four springs 322 located above are stretched, thus generating tension. When the impact rod 212 moves away from the feeding plate 312, under the action of the elastic force and tension of the eight springs 322, the feeding plate 312 is caused to shake on the four trapezoidal grooves 311 and the sliding rods 321, thereby accelerating the transportation speed.
