Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, specifically to a material hoist with an automatic vibration and unblocking device, and particularly to a hoist with an automatic vibration and unblocking device that can prevent materials from adhering to or blocking the feed inlet, hopper and discharge hopper. Background Technology

[0002] Bucket elevators are widely used vertical conveying equipment in industries such as chemical, food, building materials, and metallurgy. However, when conveying wet, sticky, or poorly flowing materials, the materials are prone to adhesion, arching, or even blockage at the feed inlet, buckets, and discharge hoppers, leading to decreased conveying efficiency and sometimes requiring shutdown for manual cleaning. This not only affects production efficiency and increases the labor intensity of workers but also poses certain safety hazards.

[0003] Currently, methods for resolving blockage issues typically include manual tapping, installing bin vibrators, or air cannons. Manual tapping is inefficient and unsafe; bin vibrators may adversely affect the overall structure of the equipment; and air cannons are costly and require a dedicated air supply. Therefore, there is an urgent need for a device that can efficiently, automatically, and locally clear blockages at common blockage points in hoists. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies and provide a material hoist with an automatic vibration and unblocking device. This hoist effectively prevents material from adhering to and clogging critical parts, such as the hopper, through automated mechanical vibration, ensuring the continuity and stability of material conveying and reducing downtime for maintenance.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a material hoist with an automatic vibration unblocking device, comprising a frame, a feed inlet and a discharge bucket disposed on the frame, and a hoisting mechanism composed of a transmission chain, a bucket and a drive sprocket, and further comprising a vibration unblocking system, wherein the vibration unblocking system includes: A vibrating shaft, which is supported on the frame; At least one vibrating component, the vibrating component including a vibrating hammer and a fastening assembly for mounting the vibrating hammer on the vibrating shaft, and a driving surface provided at one end of the vibrating hammer; A transmission mechanism for converting the rotational motion of the drive sprocket into the periodic oscillation of the vibrating component; The transmission mechanism, driven by the drive sprocket, causes the vibrating component to swing periodically, thereby causing the vibrating hammer to strike the hopper.

[0006] Furthermore, the transmission mechanism includes: At least one drive rod is connected to the drive sprocket and can rotate with it; The vibratory hammer is provided with a driving surface; As the drive rod rotates with the drive sprocket, it engages with the drive surface to drive the vibrating component to swing around the vibrating shaft.

[0007] Furthermore, the drive rods are configured as three, evenly distributed around the axis of the drive sprocket, with an angular interval of 120°.

[0008] Furthermore, the fastening assembly includes a fastener that is clamped onto the vibrating shaft, the vibrating hammer is fixed to the fastener by a connector, and the vibrating component can rotate freely around the vibrating shaft.

[0009] Furthermore, the driving surface is constructed as a curved structure.

[0010] Furthermore, the drive surface is made of a wear-resistant material, and / or the drive surface is a detachable and replaceable structure.

[0011] Furthermore, it also includes a tray for support and protection, on which the power source of the lifting mechanism is fixedly mounted or independently mounted on an external support.

[0012] Furthermore, it also includes a limiting device, which is disposed on the vibrating shaft to limit the movement range of the vibrating component.

[0013] Furthermore, the power source of the lifting mechanism is controlled by a timing controller to achieve intermittent operation.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through mechanical vibration, it acts directly on the most easily clogged part of the hopper, concentrating energy, having a large impact force, and achieving a significant unblocking effect.

[0015] 2. Controlled by a timer controller, it achieves automatic blockage clearing at set times without manual intervention, ensuring safety and efficiency, and is suitable for continuous production conditions.

[0016] 3. The crank-rocker mechanism used consists of mature mechanical components, with a robust structure and low failure rate. The two-stage reduction (belt + reducer) configuration offers flexibility and provides ample vibration torque.

[0017] 4. It avoids the long-term adverse effects of the silo wall vibrator on the overall structure and also reduces the damage to the equipment caused by manual unclogging. Attached Figure Description

[0019] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. This embodiment uses a hoist for conveying fly ash material as an example, but the application of the present invention is not limited thereto.

[0020] like Figure 1 As shown, the elevator includes a main steel frame 1. A feed inlet 2 is located at the bottom of the frame 1, through which the material to be conveyed enters. A discharge hopper 7 is located at the top of the frame 1, where the material lifted to the top is discharged.

[0021] The specific structure of the elevator includes a drive chain 3, a driven sprocket 4, buckets 5, and a drive sprocket 6. The drive chain 3 is wound around the drive sprocket 6 and the driven sprocket 4, and multiple buckets 5 are evenly fixed on the drive chain 3 at certain intervals. The drive sprocket 6 is driven by a motor to rotate, thereby driving the buckets 5 filled with material to complete the vertical lifting operation.

[0022] The integrated rapping unblocking system of this invention mainly includes a drive mechanism and a rapping component 9, which are described in detail below with reference to the accompanying drawings: The drive mechanism provides power and drives the oscillating component to oscillate periodically. In this embodiment, a crank-rocker mechanism is used to achieve this function.

[0023] like Figure 3 As shown, the power source includes a motor 13 and a reducer 12. The motor 13 is a three-phase asynchronous motor, directly connected to the reducer 12 via a shaft. The reducer 12 is a cycloidal pinwheel reducer, converting the high-speed, low-torque output of the motor 13 into a low-speed, high-torque output to meet the high torque requirements of driving the transmission chain 3. The output end of the reducer 12 is directly connected to and drives the drive sprocket 6. The drive sprocket 6 is composed of a gear shaft and two gears at both ends of the shaft.

[0024] The connection relationship of drive rod 11 is as follows Figure 3 and Figure 4 As shown. The two ends of the drive rod 11 are connected to the two gears of the drive sprocket 6. There are three drive rods 11, evenly distributed around the gear shaft at an angle of 120°.

[0025] The installation method of the vibratory shaft 10 is as follows: Figure 1 and Figure 4 As shown. The vibratory shaft 10 is rotatably supported on the frame 1 by two seated bearings, and its mounting position is adjacent to the outer wall of the feed hopper 7, which is most prone to clogging.

[0026] The rapping component 9 is the core component that directly performs the unblocking function, and it is mounted on the rapping shaft 10 via a snap-fit ​​assembly. The specific structure of the snap-fit ​​assembly is as follows: Figure 2 and Figure 6 As shown, it includes a vibratory hammer 91 and a vibratory buckle 92. One end of the vibratory hammer 91 has a curved driving surface 91a; the other end is the vibratory buckle 92, which is a U-shaped or semi-circular fastener whose inner diameter matches the outer diameter of the vibratory shaft 10. It is fastened to the vibratory shaft 10 by high-strength bolts, allowing the vibratory attachment 9 to rotate freely around the vibratory shaft 10. This connection method is robust and reliable, and the installation position on the vibratory shaft 10 can be flexibly adjusted according to the needs of unclogging.

[0027] The installation method of the vibratory hammer 91 is as follows Figure 2 and Figure 6 As shown. The vibratory hammer 91 is forged from high-carbon steel or alloy steel and is fixedly connected to the outside of the vibratory buckle 92 by bolts.

[0028] The head structure of the Vibratory Hammer 91 is as follows Figure 6 As shown, the driving surface 91a is constructed as a curved surface. When the driving rod 11 approaches the driving surface 91a, the driving rod 11 lifts the vibrating component 9 upwards. The driving rod 11 moves left and right along the curved surface of the driving surface 91a. When the driving rod 11 moves to a certain high point and disengages from the driving surface 91a, the vibrating component 9 rotates downwards along the vibrating shaft 10 and strikes the hopper 7. This effectively shakes off firmly adhered material at the moment of impact. The driving surface 91a can also be treated with a wear-resistant welding process or designed as a detachable and replaceable modular structure, with wear-resistant alloy blocks fixed by bolts for easy replacement after wear.

[0029] The installation position of tray 8 is as follows Figure 1 and Figure 3 As shown. The tray 8 is a steel structure, fixed to the frame 1 by welding or bolting. The reducer 12 and motor 13 are jointly fixed to the tray 8, providing integrated support and safety protection. The reducer 12 and motor 13 can also be independently installed on other supporting structures, such as floors, steel structures, etc.

[0030] The position of the limit device 101 is as follows Figure 5 As shown. The limiting device 101 is arranged parallel to the vibrating shaft 10, and uses an adjustable limiting bolt or limit switch to mechanically limit the left and right movement of the drive rod 11, ensuring that the swing amplitude of the vibrating shaft 10 is consistent and safe.

[0031] Control methods such as Figure 3 As shown. Motor 13 is controlled by an external timer controller (such as a PLC or time relay), and the working cycle can be preset to achieve intermittent automatic operation.

[0032] Working principle: Motor 13 operates. Power is transmitted sequentially through reducer 12 and drive sprocket 6, causing drive rod 11 to rotate circumferentially around drive shaft 6. Drive rod 11 moves along drive surface 91a, driving vibrating component 9 to move upward along vibrating shaft 10. When drive rod 11 reaches a certain high point, it leaves drive surface 91a, and vibrating component 9 swings downward along vibrating shaft 10, striking hopper 7. The three drive rods reciprocate in this way, driving vibrating component 9 to violently impact the reinforcing ribs on the outer wall of hopper 7, generating strong, concentrated impact vibration waves. These vibration waves are effectively transmitted to the interior of hopper 7, causing material adhering to the hopper wall to be shaken off, restoring smooth material flow.

[0033] This intermittent automatic operation mode utilizes the kinetic energy of the drive sprocket 6, eliminating the need for additional drive energy. While ensuring efficient blockage removal, it avoids energy waste and unnecessary equipment wear.

[0034] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
