Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, and in particular to a sealing device for the tail of a bucket elevator. Background Technology

[0002] Bucket elevators are continuous conveying equipment used for vertically lifting bulk materials. They are widely used in industries such as grain, chemical, and building materials. During operation, the drive unit drives the traction component to rotate. The buckets scoop up materials at the bottom and lift them to the top with the traction component, where the materials are then discharged. Bucket elevators have advantages such as large conveying capacity, high lifting height, stable and reliable operation, and small footprint. They can effectively improve production efficiency and reduce labor intensity, making them an important piece of equipment for achieving efficient vertical material conveying.

[0003] Existing technologies include, for example, the utility model with publication number CN219620087U. This utility model relates to the field of bucket elevators, specifically comprising a base silo and two cylinders fixedly mounted on the top of the base silo. A head is fixedly mounted at the top between the two cylinders. A head wheel assembly is rotatably connected inside the head. A driven wheel located outside the head is fixedly mounted on one side of the head wheel assembly. A drive motor is fixedly mounted on one side of the head. A drive wheel is fixedly mounted on the output end of the drive motor. A transmission belt connects the drive wheel and the driven wheel. This utility model bucket elevator features a compact structure, beautiful appearance, large conveying capacity, strong overload capacity, and energy saving. It is the preferred equipment for feeding and emptying large and medium-sized vertical silos, as well as for large and medium-sized flour mills, oil mills, and other enterprises. Multiple inspection and cleaning ports are provided on the cylinders and body, facilitating cleaning, maintenance, assembly, and repair of the bucket elevator. It is safe, stable, and has a long service life.

[0004] However, due to the lack of sealing at the tail discharge point of the bucket elevator, external impurities can easily enter the machine body through the discharge port, causing material contamination, affecting product quality, and impurities may also accelerate the wear of internal components, shorten the service life of the equipment, increase the frequency and cost of maintenance, and a large influx of impurities will hinder the smooth transportation of materials, reduce the transportation efficiency, affect the continuity and stability of the production process, and ultimately lead to a decline in production efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology that the tail discharge point of a bucket elevator lacks a seal, allowing external impurities to easily enter the machine body through the discharge port, causing material contamination, affecting product quality, and potentially accelerating wear of internal components, shortening equipment lifespan, increasing maintenance frequency and costs. A large influx of impurities can also hinder smooth material transport, reduce transport efficiency, affect the continuity and stability of the production process, and ultimately lead to a decline in production efficiency. The proposed invention is a tail sealing device for a bucket elevator.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tail sealing device for a bucket elevator, comprising a tail body and a sealing device. A motor is mounted on the surface of the tail body, and a discharge port is opened on one side of the tail body. The sealing device is disposed within the inner wall of the discharge port. The sealing device includes a rocker arm rotatably connected to the tail body. A sealing plate is fixedly connected to the surface of the rocker arm, and a rubber sleeve is fixedly connected to the upper surface of the sealing plate. The inner wall of the rubber sleeve is hollow, and a pressure spring is fixedly connected to the inner wall of the rubber sleeve. A torsion spring is fitted onto the surface of the rocker arm, and the two ends of the torsion spring are fixedly connected to the rocker arm and the tail section of the machine body, respectively. A pull-down assembly is provided on the lower surface of the sealing plate. By setting a sealing device, the opening and closing of the discharge port is automatically controlled by the gravity of the material, realizing the integration of material discharge and sealing. When the material reaches the discharge port, it squeezes the sealing plate to open the outlet, and after being discharged, it can automatically close again, effectively preventing impurities from entering the machine body through the discharge port during non-discharge periods, reducing material contamination, reducing component wear, ensuring stable operation of the equipment, and improving the cleanliness of material conveying and the service life of the equipment.

[0007] Preferably, there are two sealing plates arranged symmetrically. These sealing plates serve as control components for the opening and closing of the discharge port. When material reaches the discharge port, its own weight compresses the sealing plate, causing it to rotate around a rocker arm, thus opening the discharge port and allowing the material to be discharged smoothly. After the material has been discharged, the sealing plate quickly returns to its original position under the action of a torsion spring, closing the discharge port and achieving a tight seal.

[0008] Preferably, there are multiple pressure springs arranged in a linear array. By setting pressure springs, they are likely to play the roles of buffering, adjusting pressure, or assisting in reset. From the overall structure, when the material squeezes the sealing plate to open the discharge port, the pressure springs may be compressed to absorb some of the material impact force, reduce the damage to the sealing plate due to excessive instantaneous pressure, and at the same time make the opening process of the sealing plate more stable.

[0009] Preferably, a support plate is fixedly connected to the inner wall of the tail section body. The support plate is inclined and abuts against the sealing plate. By setting the support plate, the support plate can restrict the rotation of the sealing plate when the sealing plate is reset, reducing the possibility of the sealing plate rotating too much and causing poor sealing effect.

[0010] Preferably, the pull-down assembly includes a retaining ring, which is fixedly connected to the sealing plate. A pull rope is fixedly connected to the surface of the retaining ring, and a reel is sleeved on the end of the pull rope away from the retaining ring. By setting up the pull-down assembly, when the sealing plate is difficult to rotate normally due to material blockage or other reasons, the operator can rotate the pull rod to reel in the pull rope, forcibly pull the sealing plate to open the discharge port, quickly clear the blockage, reduce the interruption of conveying caused by material blockage, ensure the continuity of the production process, improve the equipment's ability to cope with complex working conditions, reduce downtime, and improve production efficiency.

[0011] Preferably, a pull rod is fixedly connected to the surface of the reel, which is located on the lower surface of the sealing plate. By providing the pull rod, when material discharge becomes blocked or jammed, and the normal method of opening the outlet by the material's gravity squeezing the sealing plate fails, the pull rod becomes a key emergency unblocking component. The operator grasps the pull rod and rotates it; this simple action drives the connected reel to rotate, thereby winding up the pull rope. The pull rope is connected to the sealing plate, and the winding of the rope pulls the sealing plate downwards, ultimately overcoming the material blockage and opening the outlet, thus effectively unblocking it.

[0012] Preferably, there are two pull ropes, which are respectively located below the two enclosed plates.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a sealing device, when the material reaches the discharge port, it abuts against the rubber sleeve and squeezes the sealing plate. Under the influence of the material's gravity, the rocker arm drives the sealing plate to rotate and open the discharge port, allowing the material to be discharged through the discharge port. After the material is discharged, the torsion spring loses its restraint and generates elastic force to drive the rocker arm to rotate and reset. Then, the sealing plate closes the discharge port, facilitating the sealing of the discharge port. By setting a sealing device, the opening and closing of the discharge port is automatically controlled by the material's gravity, realizing the integration of discharge and sealing. The material reaches the discharge port, squeezes the sealing plate to open the outlet, and automatically closes after discharge, effectively preventing impurities from entering the machine body through the discharge port during non-discharge periods, reducing material contamination, reducing component wear, ensuring stable equipment operation, and improving the cleanliness of material conveying and the service life of the equipment.

[0015] 2. In this utility model, by setting up a pull-down component, when the material is blocked or jammed during feeding, making it difficult for the sealing plate to rotate, the operator can grasp the pull rod and rotate it to drive the reel to wind up the pull rope. Then, the pull rope pulls the sealing plate downward to rotate and open the discharge port, facilitating the unblocking of the discharge port. By setting up the pull-down component, when the sealing plate is difficult to rotate normally due to blockage or other reasons, the operator can rotate the pull rod to wind up the pull rope, forcibly pulling the sealing plate to open the discharge port, quickly clearing the blockage, reducing the interruption of conveying caused by material blockage, ensuring the continuity of the production process, improving the equipment's ability to cope with complex working conditions, reducing downtime, and improving production efficiency.

[0023] Please see Figures 1-6 This utility model provides a technical solution: a bucket elevator tail sealing device 4, including a tail body 1 and a sealing device 4. A motor 2 is provided on the surface of the tail body 1, and a discharge port 3 is opened on one side of the tail body 1. The sealing device 4 is disposed in the inner wall of the discharge port 3.

[0024] In this embodiment: the sealing device 4 includes a rocker arm 46, which is rotatably connected to the tail section body 1. A sealing plate 41 is fixedly connected to the surface of the rocker arm 46. A rubber sleeve 43 is fixedly connected to the upper surface of the sealing plate 41. The inner wall of the rubber sleeve 43 is hollow. A pressure spring 45 is fixedly connected to the inner wall of the rubber sleeve 43. A torsion spring 47 is sleeved on the surface of the rocker arm 46. The two ends of the torsion spring 47 are fixedly connected to the rocker arm 46 and the tail section body 1, respectively. A pull-down assembly 42 is provided on the lower surface of the sealing plate 41. By setting the sealing device 4, the opening and closing of the discharge port 3 is automatically controlled by the gravity of the material, realizing the integration of material discharge and sealing. When the material reaches the discharge port 3, it squeezes the sealing plate 41 to open the outlet. After discharge, it can automatically close again, effectively preventing impurities from entering the machine body through the discharge port during non-discharge periods, reducing material contamination, reducing component wear, ensuring stable operation of the equipment, improving the cleanliness of material conveying and the service life of the equipment.

[0025] Specifically, there are two sealing plates 41 arranged symmetrically. These sealing plates 41 serve as the opening and closing control components for the discharge port 3. When material reaches the discharge port 3, its own weight compresses the sealing plates 41, causing them to rotate around the rocker arm 46, thus opening the discharge port 3 and allowing the material to be discharged smoothly. After the material has been discharged, the sealing plates 41 quickly return to their original position under the action of the torsion spring 47, closing the discharge port 3 and achieving a tight seal.

[0026] Specifically, there are multiple pressure springs 45 arranged in a linear array. By setting up the pressure springs 45, the pressure springs 45 are likely to play the role of buffering, adjusting pressure, or assisting in reset. From the overall structure, when the material squeezes the sealing plate 41 to open the discharge port 3, the pressure springs 45 may be compressed to absorb some of the material impact force, reduce the damage to the sealing plate 41 due to excessive instantaneous pressure, and at the same time make the opening process of the sealing plate 41 more stable.

[0027] Specifically, a support plate 44 is fixedly connected to the inner wall of the tail section 1. The support plate 44 is inclined and abuts against the sealing plate 41. By setting the support plate 44, the support plate 44 can restrict the rotation of the sealing plate 41 when the sealing plate 41 is reset, thereby reducing the situation where the sealing plate 41 rotates too much and causes poor sealing effect.

[0028] Specifically, the pull-down assembly 42 includes a retaining ring 422, which is fixedly connected to the closing plate 41. A pull rope 421 is fixedly connected to the surface of the retaining ring 422, and a roller 423 is sleeved on the end of the pull rope 421 away from the retaining ring 422.

[0029] In this embodiment: by setting up the pull-down component 42, when the material makes it difficult for the sealing plate 41 to rotate normally due to blockage or other reasons, the operator can rotate the pull rod 424 to wind up the pull rope 421, forcibly pull the sealing plate 41 to open the discharge port 3, quickly clear the blockage, reduce the interruption of conveying caused by material blockage, ensure the continuity of the production process, improve the equipment's ability to cope with complex working conditions, reduce downtime, and improve production efficiency.

[0030] Specifically, a pull rod 424 is fixedly connected to the surface of the spool 423, and the spool 423 is located on the lower surface of the enclosed plate 41.

[0031] In this embodiment: By setting up the pull rod 424, when the material discharge becomes blocked or jammed, and the normal method of opening the discharge port 3 by the pressure of the material's gravity on the sealing plate 41 fails, the pull rod 424 becomes a key operating component for emergency unblocking. The operator grasps the pull rod 424 and rotates it. This simple action drives the connected reel 423 to rotate, thereby winding up the pull rope 421. The pull rope 421 is connected to the sealing plate 41. The winding of the pull rope 421 pulls the sealing plate 41 downward, ultimately overcoming the obstruction of the material blockage and opening the discharge port 3, thus effectively unblocking the discharge port 3.

[0032] Specifically, there are two pull ropes 421, which are respectively set below the two closed plates 41.

[0033] Working principle: By setting up the sealing device 4, when the material reaches the discharge port 3, it abuts against the rubber sleeve 43 and squeezes the sealing plate 41. Under the influence of the material's gravity, the rocker arm 46 drives the sealing plate 41 to rotate and open the discharge port 3, and the material is discharged through the discharge port 3. After the material is discharged, the torsion spring 47 loses its restraint and generates elastic force to drive the rocker arm 46 to rotate and reset. Then the sealing plate 41 closes the discharge port 3, which facilitates the sealing of the discharge port 3. By setting up the sealing device 4, the opening and closing of the discharge port 3 is automatically controlled by the gravity of the material, realizing the integration of discharge and sealing. When the material reaches the discharge port 3, it squeezes the sealing plate 41 to open the outlet, and after discharge, it can automatically close again, effectively preventing impurities from entering the machine body through the discharge port during non-discharge periods, reducing material pollution, reducing component wear, ensuring stable operation of the equipment, improving the cleanliness of material conveying and the service life of the equipment.

[0034] By setting up the pull-down assembly 42, when the material is blocked or jammed during feeding, making it difficult for the closing plate 41 to rotate, the pull rod 424 is grasped and rotated to drive the reel 423 to wind up the pull rope 421. Then the pull rope 421 pulls the closing plate 41 downward to open the discharge port 3, making it easier to clear the discharge port 3. By setting up the pull-down assembly 42, when the material is blocked or other reasons that make it difficult for the closing plate 41 to rotate normally, the operator can rotate the pull rod 424 to wind up the pull rope 421, forcibly pull the closing plate 41 to open the discharge port 3, quickly clear the blockage, reduce the interruption of the conveying caused by the material blockage, ensure the continuity of the production process, improve the equipment's ability to cope with complex working conditions, reduce downtime, and improve production efficiency.
