Description

Technical Field

[0001] This utility model relates to the field of logistics and conveying technology, specifically to a piezoelectric circular vibrating storage and unloading hopper. Background Technology

[0002] In industrial production (such as chemical, food processing, and building materials production) and material handling, material storage and unloading equipment is a crucial link connecting material storage and subsequent processing. Its unloading efficiency and stability directly affect the operating rhythm of the entire production line. Traditional external vibrating hoppers typically use a motor-driven eccentric block or a pneumatic hammer to strike the outer wall of the hopper body to achieve material vibration unloading. While this method can promote material flow to some extent, the vibration energy must be transferred through the hopper body to the internal material, resulting in significant energy loss. This leads to limited effectiveness in clearing easily agglomerated and poorly flowing materials (such as flour, gypsum powder, and coal powder), and "bridging" and "blockage" phenomena are still prone to occur. At the same time, long-term impact or high-frequency vibration on the outer wall of the hopper can cause cracks in the welds of the hopper body and wear and deformation of the inner wall, shortening the service life of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a piezoelectric circular vibrating storage hopper, which has the advantage of clearing materials from the inside of the hopper and solves the problem that striking the outer wall of the hopper body will reduce the service life of the hopper body.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A piezoelectric circular vibrating hopper includes a mounting frame and a hopper body mounted on the mounting frame. The hopper body is equipped with a vibration component and a drainage component. The vibration component includes multiple load-bearing sleeves fixed to both sides of the inner wall of the hopper body. Sliding rods are slidably connected between the load-bearing sleeves. Multiple vibrating plates are fixedly connected to the multiple sliding rods. Sliding discs that are slidably connected to the load-bearing sleeves are fitted on the sliding rods. Springs are fixedly connected between the sliding discs and the inner wall of the load-bearing sleeves. The ends of the sliding rods extend to the outside of the hopper body. Connecting strips are fixedly connected to the ends of the multiple sliding rods. A transmission component for pushing the connecting strip to move is provided on the mounting frame.

[0005] Preferably, the transmission component includes a motor fixedly mounted on a mounting bracket, with a transmission shaft fixedly connected to the output end of the motor, and multiple cams eccentrically mounted on the transmission shaft, the cams being located on the outer side of the connecting strip.

[0006] Preferably, the unblocking component includes an electric telescopic rod fixed to the hopper body, a load-bearing block fixed to the free end of the electric telescopic rod, a damping bearing fixed to the load-bearing block, a rotating shaft rotatably mounted on the damping bearing, a bushing fitted on the rotating shaft, an L-shaped rod fixed to the bushing, and a conical head fixed to the L-shaped rod corresponding to the discharge port at the bottom of the hopper body.

[0007] Preferably, a spur gear is fixedly connected to the end of the rotating shaft, and a rack that meshes with the spur gear is fixedly connected to the hopper body.

[0008] Preferably, a ring-shaped weight sensor is fixedly connected to the mounting frame, and a connecting ring is fitted onto the hopper body. The connecting ring rests on the ring-shaped weight sensor, and the size of the hopper body is compatible with the mounting frame.

[0009] Preferably, the spring is a compression spring, and the outer surface of the spring is coated with a zinc-nickel alloy anti-rust coating.

[0010] By employing the above technical solution, this utility model provides a piezoelectric circular vibrating storage and feeding hopper, which has at least the following beneficial effects: 1. This piezoelectric circular vibrating storage hopper, by setting up a vibration component, uses a load-bearing sleeve to provide directional support for the slide rod, and a sliding disc and spring to convert the power of the transmission component into the reciprocating vibration of the slide rod, to achieve precise vibration of the material from inside the hopper. This not only avoids damage to the hopper body from external impacts, but also breaks up material agglomeration, significantly improving the feeding speed and uniformity.

[0011] 2. This piezoelectric circular vibrating hopper, through the collaboration of a clearing component, a ring weight sensor, and a microcontroller, allows the ring weight sensor to monitor the material weight in real time. When the weight exceeds a threshold, the microcontroller triggers an electric telescopic rod, which drives a conical head to precisely steer and clear the blockage. It can automatically detect material blockage and trigger the clearing action without manual intervention, effectively reducing production interruptions, ensuring the continuity of material feeding operations, and reducing labor and time costs.

[0014] 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.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of the piezoelectric circular vibrating storage hopper provided by this utility model.

[0016] Example 1: Relying solely on the material's own gravity for feeding can lead to "bridging" and "blockage" for materials that are prone to clumping and have poor flowability (such as flour and gypsum powder), significantly reducing the feeding speed or even causing it to stop completely. To solve these problems, a combination of... Figures 1-3 As shown, the piezoelectric circular vibrating storage hopper provided by this utility model includes a mounting frame 100 and a hopper body 101 mounted on the mounting frame 100. The hopper body 101 is provided with a vibration component 200 and a dredging component 300. This vibration method does not require direct impact or sliding on the hopper body 101, and can directly vibrate the material from the inside, which can avoid damage to the hopper body 101 and improve the feeding speed. If the traditional method of externally impacting the hopper is used instead, long-term impact will cause cracks in the welds of the hopper body 101 and deformation of the inner wall, shortening the equipment life. Furthermore, the vibration energy cannot be transmitted to the material interior, resulting in a far inferior unblocking effect compared to "internal vibration." To solve these problems, the vibration assembly 200 includes multiple load-bearing sleeves 207 fixed to both sides of the inner wall of the hopper body 101. Sliding rods 201 are slidably connected between the load-bearing sleeves 207. Multiple vibrating plates 202 are fixedly connected to the multiple sliding rods 201. A sliding disc 209, slidably connected to the load-bearing sleeve 207, is fitted onto the sliding rod 201. A spring 208 is fixed between the sliding disc 209 and the inner wall of the load-bearing sleeve 207. The end of the sliding rod 201 extends... Extending to the outside of the hopper body 101, the ends of multiple sliding rods 201 are jointly fixed with connecting strips 203. The mounting frame 100 is provided with a transmission component for pushing the connecting strips 203 to move. When the transmission component moves to one side, the sliding disc 209 moves with the sliding rods 201. Subsequently, the sliding disc 209 compresses and stretches the spring 208. Then, under the action of the spring 208, the sliding rod 201 vibrates, which in turn drives the vibrating plate 202 to vibrate. The vibration of the sliding rod 201 can be synchronously transmitted to multiple vibrating plates 202, increasing the vibration area. This ensures that materials in different areas of the hopper body 101 are affected by vibration, effectively preventing local accumulation of materials and improving the uniformity of material feeding.

[0017] Specifically, the transmission component includes a motor 204 fixedly mounted on the mounting bracket 100. The output end of the motor 204 is fixedly connected to a transmission shaft 205. Multiple cams 206 are eccentrically mounted on the transmission shaft 205. The cams 206 are located outside the connecting bar 203. When the motor 204 starts, it drives the transmission shaft 205 to rotate. The cams 206 rotate with the transmission shaft 205 and come into contact with the connecting bar 203, causing it to move to one side. Then, the cams 206 disengage from the connecting bar 203, and the connecting bar 203 can be reset. The elasticity of the spring 208 provides continuous power for the vibration of the slide bar 201, ensuring a stable vibration frequency and avoiding a decrease in material feeding efficiency due to weakened vibration.

[0018] Furthermore, spring 208 is a compression spring 208, and the outer surface of spring 208 is coated with a zinc-nickel alloy anti-rust coating. The zinc-nickel alloy coating has excellent corrosion resistance and can effectively isolate corrosive media such as air and moisture from contacting the surface of spring 208, preventing spring 208 from weakening its elasticity or failing due to rust, which is beneficial to improving the service life of spring 208.

[0019] As can be seen from the embodiments, the motor 204 drive method has a higher degree of automation compared to manual or pneumatic drive, reduces manual operation intervention, lowers labor costs, and facilitates the automated operation of the equipment by controlling the start and stop of the motor 204.

[0020] Example 2: Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, the unblocking component 300 includes an electric telescopic rod 301 fixedly connected to the hopper body 101. A load-bearing block 302 is fixedly connected to the free end of the electric telescopic rod 301. A damping bearing 303 is fixedly mounted on the load-bearing block 302. A rotating shaft 304 is rotatably mounted on the damping bearing 303. A bushing 305 is fitted onto the rotating shaft 304. An L-shaped rod 306 is fixedly connected to the bushing 305. A conical head 307 corresponding to the discharge port at the bottom of the hopper body 101 is fixedly connected to the L-shaped rod 306. When material in the hopper body 101 becomes blocked at the discharge port, the electric telescopic rod 301... The contraction of the free end causes the load-bearing block 302 to move upward. The damping bearing 303 on the load-bearing block 302 moves with it, and then the damping bearing 303 drives the L-shaped rod 306 to move. Subsequently, the L-shaped rod 306 rotates, causing the conical head 307 to face upward. The conical head 307 moves upward and enters the hopper body 101 through the discharge port to clear the material. When a blockage occurs, the conical head 307 can directly extend into the hopper to clear the blockage. Compared with traditional clearing methods such as external tapping, it can directly act on the blockage point, making clearing more efficient and thorough, avoiding material interruption caused by blockage, and ensuring the continuity of operation.

[0021] Specifically, a spur gear 308 is fixedly connected to the end of the rotating shaft 304, and a rack 309 is fixedly connected to the hopper body 101 to mesh with the spur gear 308. The spur gear 308 moves with the rotating shaft 304, and then meshes with the rack 309 to make it rotate. The spur gear 308 drives the rotating shaft 304 to rotate. Then the spur gear 308 disengages from the rack 309 and does not continue to drive the rotating shaft 304 to rotate. Instead, it drives the conical head 307 on the L-shaped rod 306 to rotate. After the unblocking is completed, the spur gear 308 moves downward and meshes with the rack 309 again to drive the conical head 307 on the L-shaped rod 306 to reset. This can accurately transmit the rotation angle, so that the position of the conical head 307 is consistent with each rotation and reset, improving the reliability of unblocking and reset.

[0022] Furthermore, a ring-shaped weight sensor 102 is fixedly connected to the mounting frame 100, and a connecting ring 103 is fitted onto the hopper body 101. The connecting ring 103 rests on the ring-shaped weight sensor 102. The size of the hopper body 101 is adapted to the mounting frame 100. A microcontroller is also provided. When the ring-shaped weight sensor 102 detects that the material in the conical body exceeds the preset limit, it activates the electric telescopic rod 301 so that the conical head 307 clears the material in the hopper body 101. The clearing is triggered by the weight threshold, which can prevent the material in the hopper from accumulating excessively and exceeding the bearing limit, and prevent the hopper body 101 or the mounting frame 100 from being damaged due to overload.

[0023] The ring weight sensor 102 is electrically connected to the microcontroller via a wire. The sensor transmits the converted weight electrical signal to the microcontroller in real time. The microcontroller has a built-in preset weight threshold (such as the abnormal weight value when the material is blocked, the weight range value of normal feeding, etc.). After receiving the signal, it will compare and analyze the real-time detected weight electrical signal with the preset threshold to determine whether the weight of the material in the hopper is within the normal range, or whether the conditions for triggering subsequent actions (such as starting the unblocking component 300) have been met. When the microcontroller determines that the material weight is abnormal (such as exceeding the preset blockage threshold), it will generate corresponding control commands based on the preset program to provide signal basis for subsequent activation of components such as the electric telescopic rod 301. If the weight is within the normal range, no trigger command will be generated to ensure that the equipment only activates relevant components when necessary, realizing on-demand control. Its core is to transform the material weight information into a signal that can be used for intelligent control of the equipment through the collaboration between components.

[0024] As can be seen from the above embodiments: First, the material enters the hopper body 101, and then is discharged through the discharge port. The motor 204 drives the transmission shaft 205 to rotate, and the cam 206 rotates accordingly to push the connecting bar 203, which drives the slide bar 201 and the sliding plate 209 to move, compressing the spring 208 with the zinc-nickel alloy coating. After the cam 206 disengages, the spring 208 resets, causing the slide bar 201 to vibrate back and forth, driving the vibrating plate 202 to vibrate and discharge the material. At the same time, the ring weight sensor 102 detects the weight of the material in real time through the connecting ring 103 and is connected to the microcontroller. When the weight exceeds the preset value, the electric telescopic rod 301 retracts, driving the load-bearing block 302, the damping bearing 303 and the bushing 305 to move upward. The spur gear 308 meshes with the rack 309 to rotate the rotating shaft 304, which in turn causes the L-shaped rod 306 to drive the conical head 307 upward, passing through the discharge port to clear the blockage. After the blockage is cleared, the telescopic rod extends and resets, and the spur gear 308 re-engages, causing the conical head 307 to return to its original position. When the weight drops to the normal range, the single-chip microcomputer shuts down the motor 204 and the telescopic rod.
