Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, in particular to a bucket elevator with a slip detection device. Background Art

[0002] A bucket elevator is a device used for vertical conveying of bulk materials. Materials are loaded primarily through a bucket, which then ascends or descends along a conveyor chain or belt. A bucket elevator typically consists of a loading area, a lifting chain (or belt), a bucket, a drive mechanism, a material guide, and a discharge area. Bucket elevators are widely used in various industrial sectors, such as grain processing, cement production, mining, chemical engineering, and metallurgy, for conveying granular, powdered, or lumpy bulk materials such as grain, limestone, ore, and fertilizer. Their key features include: 1. Efficient Conveying: Bucket elevators enable efficient vertical conveying, improving material handling efficiency. 2. High Load Capacity: Bucket elevators can be designed to meet specific lifting heights and conveying capacities, offering a high load capacity. 3. Simple Structure: Bucket elevators have a simple structure and are easy to install, maintain, and operate. 4. Small Footprint: Vertical conveying and a small footprint make them suitable for limited sites. 5. Safety and Reliability: Well-designed safety devices ensure safe operation. It should be noted that when using a bucket elevator, the model should be selected according to parameters such as material properties, particle size, temperature, etc., and equipment maintenance should be performed regularly to ensure safe operation of the equipment and extend its service life.

[0003] When using an existing bucket elevator, when the friction between the transmission wheel and the conveyor belt is insufficient, the material is prone to slip during the lifting process. Once slipping occurs, it will directly affect the conveying efficiency and stability of the elevator. In order to be able to detect the slipping of the elevator in time, a bucket elevator with a slip detection device is urgently needed. Utility Model Content

[0008] A bucket elevator with a slip detection device comprises a frame, a driving motor is installed on the outer side surface of the upper part of the frame, the output end of the driving motor is fixedly connected to the first rotating shaft, bearings are provided at the connection between the two ends of the first rotating shaft and the frame, the outer surface of the first rotating shaft is fixedly connected to the driving wheel, the inner side surface of the lower part of the frame is rotatably connected to the second rotating shaft through the bearing, the surface of the second rotating shaft is fixedly connected to the driven wheel, the surfaces of the driving wheel and the driven wheel are provided with a conveyor belt, the outer surface of the conveyor belt is installed with a hopper, the side surface of the lower part of the frame is fixedly connected to a fixed block, the surface of the fixed block is rotatably connected to the third rotating shaft through the bearing, the outer end surface of the third rotating shaft is fixedly connected to the gear, and the outer surface of the conveyor belt is installed with a toothed belt.

[0014] The utility model provides a bucket elevator with a slip detection device, which has the following beneficial effects:

[0015] 1. A bucket elevator with a slip detection device has a slip detection alarm effect through the arrangement of a toothed belt, a third rotating shaft, a speed sensor, a gear, a controller and an alarm. When in use, the bucket elevator drives the first rotating shaft to rotate through the driving motor, and the first rotating shaft then drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the conveyor belt. While the conveyor belt is transmitted on the surface of the driving wheel and the driven wheel, it drives the bucket to move and completes the lifting and transmission of the material. During the operation, the conveyor belt drives the toothed belt arranged on the surface of the conveyor belt to move together. Due to the meshing transmission between the toothed belt and the gear, the gear is driven to rotate through the toothed belt, and the gear then drives the third rotating shaft to rotate together. The outer end of the third rotating shaft is arranged inside the speed sensor, and the speed or frequency of the rotation of the third rotating shaft is measured by the speed sensor. The number is converted into an electrical signal output. Common speed sensors include Hall sensors, magnetoelectric sensors, photoelectric sensors, etc. The speed sensor can obtain the speed of the third rotating shaft. When the friction between the driving wheel and the conveyor belt decreases, the driving wheel slips, which will cause the transmission of the conveyor belt to slow down or stop intermittently. As the transmission of the conveyor belt decreases, the speed of the gear driven by the toothed belt decreases. At this time, the speed sensor detects that the speed of the third rotating shaft has decreased, which means that slippage has occurred during the conveying process. At this time, the speed sensor sends the detection signal to the controller, and the controller controls the alarm to sound an alarm, and the controller controls the drive motor to stop working. After the staff finds the alarm signal, they check the cause of the slip in time, which plays a role in slip detection and stopping after slipping, thereby achieving the purpose of slip detection alarm.

The side surface of the lower part of the frame 1 is fixedly connected to a fixed block 10. The surface of the fixed block 10 is rotatably connected to a third rotating shaft 11 through a bearing. The outer end face of the third rotating shaft 11 is equipped with a speed sensor 12. The inner end face of the third rotating shaft 11 is fixedly connected with a gear 13. The teeth on the surface of the toothed belt 9 are matched with the teeth on the surface of the gear 13. The surface of the toothed belt 9 is meshed with the gear 13. The outer surface of the conveyor belt 7 is equipped with a toothed belt 9. The outer surface of the lower part of the frame 1 is equipped with a controller 14. The outer surface of the lower part of the frame 1 is equipped with an alarm 15. The speed sensor 12 is electrically connected to the controller 14 through a wire. The controller 14 is electrically connected to the alarm 15 through a wire. The controller 14 is electrically connected to the drive motor 2 through a wire.

[0025] In order to achieve the purpose of slip detection alarm, when in use, the bucket elevator is provided with the effect of slip detection alarm through the arrangement of the toothed belt 9, the third rotating shaft 11, the speed sensor 12, the gear 13, the controller 14 and the alarm 15. When in use, the bucket elevator drives the first rotating shaft 3 to rotate through the driving motor 2, and the first rotating shaft 3 then drives the driving wheel 4 to rotate, and the driving wheel 4 drives the driven wheel 6 to rotate through the conveyor belt 7. While the conveyor belt 7 is transmitted on the surface of the driving wheel 4 and the driven wheel 6, it drives the hopper 8 to move and completes the lifting and transmission of the material. During the operation, while the conveyor belt 7 is transmitting, it drives the toothed belt 9 set on the surface of the conveyor belt 7 to move together.

When the friction between the driving wheel 4 and the conveyor belt 7 decreases, the driving wheel 4 slips, which will cause the transmission of the conveyor belt 7 to slow down or stop intermittently. As the transmission of the conveyor belt 7 decreases, the speed of the gear 13 driven by the toothed belt 9 decreases. At this time, the speed sensor 12 detects that the speed of the third rotating shaft 11 has decreased, which means that slippage has occurred during the transportation process. At this time, the speed sensor 12 sends the detection signal to the controller 14, and the controller 14 controls the alarm 15 to sound an alarm. The controller 14 controls the drive motor 2 to stop working. After the staff detects the alarm signal, they check the cause of the slip in time, which plays a role in slip detection and stopping after slipping, thereby achieving the purpose of slip detection alarm.
