Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, specifically a bucket elevator designed to prevent material leakage. Background Technology

[0002] Bucket elevators drive a series of buckets to circulate within a closed shell through traction components, enabling automated lifting and transfer of materials from low to high. They can handle powdery, granular, or small lump materials. Through feeding, lifting, and unloading control, they stably transport materials from their initial position to the target height or adjacent equipment. They are used in material loading and unloading, mixing, metering, and process flow connection in industrial production, and are key equipment for vertical material transfer in modern automated production lines.

[0003] Currently, in actual operation, bucket elevators often experience problems due to the large particle size differences, strong adhesion, or easy hygroscopic agglomeration of some raw materials. These materials tend to form agglomerated structures or get stuck in the gaps between conveying components after entering the bucket elevator, leading to internal seal failure and raw material leakage. Especially at the feed end, when material accumulates and blocks, not only will the obstructed material flow force the equipment to operate under overload, significantly reducing conveying efficiency, but the continuous compression of the material will also cause irreversible wear and deformation to core components such as buckets and chains. Long-term blockage operation may also lead to serious malfunctions such as motor burnout and shell cracking, threatening the continuous and stable operation of the entire production line. Utility Model Content

[0004] The purpose of this invention is to provide a bucket elevator that prevents material leakage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof bucket elevator, comprising a bucket elevator, and further comprising: A feed hopper is fixed to the surface of a bucket elevator. A protective shell is fixed to the surface of the feed hopper. A fixing block is fixed to the inner cavity of the protective shell. A motor is fixed to the surface of the fixing block. A rotating mechanism is provided in the inner cavity of the feed hopper. A vibration mechanism is provided on the surface of the rotating mechanism.

[0006] Preferably, the rotating mechanism further includes: A rotating shaft is fixed to the output end of a motor. Several agitator rods are fixed on the surface of the rotating shaft. A limit block slides on the surface of the rotating shaft. A support rod is fixed on the surface of the limit block.

[0007] Preferably, the vibration mechanism further includes: A rotating plate is fixed to one end of a rotating shaft. Several vibrating balls are fixed on the surface of the feed hopper. Several sleeves are fixed on the surface of the rotating plate. Springs are fixed inside the sleeves. Elastic rods slide inside the sleeves.

[0008] Preferably, the motor is a servo motor and has a dual-axis power supply inside.

[0009] Preferably, the spring is made of stainless steel and has high resistance to metal fatigue.

[0010] Preferably, the number of stirring rods is 12, and they are divided into two types, with the upper one being longer and the lower one being shorter.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention introduces a rotating mechanism and a vibration mechanism working in tandem. The rotating mechanism drives the internal rotating components to rotate forward, using mechanical force to dynamically disperse agglomerated raw materials, effectively breaking down the adhesive structure between material particles and reducing the risk of blockage in the conveying channel from the source. The vibration mechanism generates high-frequency micro-amplitude vibrations through the spring components triggered by the rotating mechanism, causing the material to form a continuous flow state under the vibration action. This effectively eliminates the arching phenomenon caused by static pressure of the material in the hopper, thereby reducing the leakage of raw materials due to internal arching and improving the flowability of raw materials in the conveying system. It is suitable for continuous conveying scenarios of high humidity and easily sticky materials, providing a reliable technical solution for ensuring the stable operation of the production line.

[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] Please see Figure 1-4 As shown, a bucket elevator for preventing material leakage includes a bucket elevator body 1, a feed hopper 3 fixed to the surface of the bucket elevator body 1, a protective shell 2 fixed to the surface of the feed hopper 3, a fixing block 5 fixed to the inner cavity of the protective shell 2, a motor 4 fixed to the surface of the fixing block 5, a rotating mechanism 6 provided in the inner cavity of the feed hopper 3, and a vibration mechanism 7 provided on the surface of the rotating mechanism 6.

[0016] The feed hopper 3 is fixed to the surface of the bucket elevator body 1 and is used to transport the input raw materials. The arc-shaped feed inlet can more smoothly transport the raw materials into the interior and reduce blockage.

[0017] The protective shell 2 is fixed to the surface of the feed hopper 3 to protect the internal machinery and prevent dust or debris from affecting the machinery.

[0018] The fixing block 5 is fixed to the surface of the feed hopper 3 to fix the motor 4 and ensure that the output of the motor 4 is stable when the machine vibrates.

[0019] The motor 4 is fixed to the surface of the fixed block 5, providing power to the equipment and driving its internal output rotation.

[0020] Motor 4 is a servo motor with internal dual-axis power to ensure stable rotation and prevent damage caused by excessive resistance from raw materials.

[0021] The rotating mechanism 6 is located inside the feed hopper 3. By rotating, the raw materials fed into the hopper have a certain degree of fluidity, thereby reducing the possibility of accumulation and blockage. Furthermore, the rotation can break up the clumps of raw materials through external force, allowing them to better carry out the work in the next stage and reducing blockages caused by different sizes.

[0022] The rotating mechanism 6 includes a rotating shaft 61 fixed to the output end of the motor 4. Several agitator rods 62 are fixed on the surface of the rotating shaft 61. A limit block 63 slides on the surface of the rotating shaft 61. A support rod 64 is fixed on the surface of the limit block 63.

[0023] The rotating shaft 61 rotates within the inner cavity of the feed hopper 3. Driven by the motor 4, it drives other components on its surface to move, achieving a large-area transmission effect. Under the action of a single output mode, it drives the interior to operate at high speed.

[0024] The stirring rods 62 are fixed to the surface of the rotating shaft 61, and there are 12 rods in total. They are divided into two types: the upper one is longer and the lower one is shorter. They are used to stir the raw materials to reduce the probability of blockage. While the stirring rods 62 are stirring, they can break up larger pieces of raw materials, thereby reducing the possibility of arching caused by different sizes of raw materials.

[0025] The limiting block 63 slides on the surface of the rotating shaft 61 to limit the range of rotation of the rotating shaft 61, stabilize its rotation area, and ensure that it will not deflect due to vibration when rotating, thereby causing the stirring rod 62 fixed on its surface to rotate unstably.

[0026] The support rods 64 are fixed to the inner wall of the feed hopper 3, and there are four of them. By fixing and limiting the limit block 63, the rotation of the stirring rod 62 inside is restricted. Through multi-directional fixing, the stability of its rotation can be greatly improved.

[0027] The vibration mechanism 7 is installed on the surface of the feed hopper 3. By rotating continuously, it drives the elastic vibration inside the feed hopper 3 to vibrate continuously in small amplitude. Under the drive of vibration, the raw materials accumulated inside the feed hopper become fluid, thereby reducing the probability of accumulation.

[0028] The vibration mechanism 7 includes a rotating plate 71 fixed to one end of the rotating shaft 61, a number of vibrating balls 72 fixed on the surface of the feed hopper 3, a number of sleeves 73 fixed on the surface of the rotating plate 71, a spring 74 fixed in the inner cavity of the sleeve 73, and a spring rod 75 sliding in the inner cavity of the sleeve 73.

[0029] The rotating plate 71 is fixed to one end of the rotating shaft 61 and is used to support the vibrating parts and provide support for their rotation.

[0030] 100 vibrating balls 72 are fixed to the surface of the feed hopper 3. By continuously squeezing the elastic rod 75, it generates high-frequency micro-vibrations during compression and ejection, thereby driving the feed hopper 3 fixed to it to vibrate and solve the arching problem.

[0031] Sleeves 73 are fixed to the surface of rotating plate 71, and there are 100 of them. They are used to limit the sliding of elastic rod 75 and limit the continuous compression of spring 74 inside.

[0032] Spring 74 is fixed to the surface of elastic rod 75. By continuously compressing and releasing, it drives the elastic rod 75, which is fixed at one end, to move continuously, controlling its vibration and thus reducing the probability of internal arching.

[0033] The spring 74 is made of stainless steel and has high resistance to metal fatigue, allowing it to maintain its original state during compression and release at high frequencies.

[0034] The elastic rod 75 slides in the inner cavity of the sleeve 73. Driven by the spring 74, it continuously slides over the surface of the vibrating ball 72. After reaching the top, it will quickly descend, generating vibrations continuously during the process, thereby achieving the purpose.

[0035] Working principle: After the raw materials are fed into the hopper 3, the operator starts the motor 4. Driven by the motor 4 and limited by the limit block 63, the rotating shaft 61 rotates continuously. As the rotating shaft 61 rotates, the stirring rod 62 fixed on it continuously stirs the raw materials in the inner cavity of the hopper 3, breaking up any possible agglomerates and making the raw materials flow. At the same time, the rotating plate 71 at the bottom rotates continuously under the rotation of the rotating shaft 61, driving the sleeve 73 on it to rotate. The elastic rod 75 inside the sleeve 73 continuously slides and contacts the vibrating ball 72. Under the continuous up and down sliding, high-frequency fine vibration is generated. Under this vibration, the raw materials in the hopper 3 are in a flowing state, which can further reduce the probability of blockage and thus reduce the possibility of blockage. In addition, with the cooperation of the rotating mechanism 6, the blockage problem caused by different sizes of raw materials is also reduced.
