Description

Technical Field

[0001] The utility model relates to the technical field of drum drive structures, and particularly relates to a drum drive structure of a belt conveyor. Background Technique

[0002] The drum drive structure of a belt conveyor is a key part in a belt conveyor. It is responsible for providing power for the conveyor belt to ensure the smooth transportation of materials. The drum drive structure usually includes components such as an electric motor and a driving drum. These components work together to transmit the rotational power of the electric motor to the driving drum, and then drive the conveyor belt to operate.

[0003] The common drum drive structure generally connects the electric motor and the drum through a rotating shaft. The electric motor drives the rotating shaft to drive the drum to rotate. However, the drum is a vulnerable part in the belt conveyor, and the electric motor also needs regular maintenance. In the existing structure, it is inconvenient to disassemble the drum after it is connected to the electric motor. It is often necessary to stop the equipment for a long time to replace the drum or maintain the electric motor. Therefore, those skilled in the art have provided a drum drive structure of a belt conveyor to solve the problems raised in the above background technique. Content of the Utility Model

[0006] (2) Technical Solutions

[0007] To achieve the above purpose, the utility model provides the following technical solution: A drum drive structure of a belt conveyor includes a bracket. One end of the upper part of the bracket is rotatably installed with a rotating sleeve. The other end of the upper part of the bracket is provided with a clamping groove. One end of the upper side of the clamping groove is rotatably connected with a pressing plate. One end of the pressing plate is threadedly connected with a first bolt. A drum is arranged above the bracket. One end of the drum is movably inserted into the rotating sleeve. The other end of the drum is provided with a second gear. A first gear is arranged below the second gear. A spline groove is opened in the middle of the first gear. A trolley is arranged on one side of the bracket close to the first gear. An electric motor is installed on the trolley. The output end of the electric motor is drivingly connected with a spline shaft.

[0008] Preferably, the spline shaft is inserted into the spline groove in the middle of the first gear.

[0009] Preferably, the first gear is in meshing contact with the second gear. When the trolley fits against the bracket, the spline shaft on the motor is inserted into the spline groove in the middle of the first gear. Thus, the motor drives the spline shaft to rotate. Subsequently, the spline shaft drives the first gear to rotate, and finally the first gear drives the drum with the second gear to rotate, thereby achieving the conveying effect of the belt conveyor.

[0010] Preferably, one end of the drum with the second gear is received by the card slot. The pressing plate fits against the end of the drum with the second gear. The first bolt is threadedly connected to the bracket. When the drum needs to be replaced, the first bolt is screwed out and the pressing plate is flipped. At this time, one end of the drum with the second gear can be lifted, and then the rotating sleeve is pulled out for replacement.

[0011] Preferably, a second bolt is threadedly connected to the trolley. The second bolt is threadedly connected to the bracket. Universal wheels are provided at the bottom of the trolley. When maintaining the motor, the second bolt can be screwed out, and the motor can be transported to the repair location by the trolley.

Please refer to Figure 1 , Figure 2 , Figure 3, the spline shaft 12 is inserted into the spline groove 4 in the middle of the first gear 3. When the trolley 10 is in contact with the bracket 1, the spline shaft 12 on the motor 11 is inserted into the spline groove 4 in the middle of the first gear 3, so that the motor 11 drives the spline shaft 12 to rotate. Subsequently, the spline shaft 12 drives the first gear 3 to rotate, and the rotation of the first gear 3 ultimately drives the drum 8 with the second gear 9 to rotate, thereby realizing the conveying effect of the belt conveyor. One end of the drum 8 with the second gear 9 is received by the card slot 5, the pressing plate 6 is in contact with one end of the drum 8 with the second gear 9, and the first bolt 7 is threadedly connected to the bracket 1. When the drum 8 needs to be replaced, the first bolt 7 is screwed out and the pressing plate 6 is flipped.
