Description

Technical Field

[0001] The utility model relates to the technical field of grading wheels, in particular to an adjustable grading wheel structure. Background Art

[0002] The grading wheel is a common industrial equipment used to grade materials according to factors such as quality and size. Its structure and working principle vary depending on the material and process requirements, and can be divided into many types. Common grading wheels include single-layer grading wheels, multi-layer grading wheels and rotary grading wheels. The grading wheel is usually composed of a circular frame, which contains multiple mutually perpendicular blades or partitions. These scrapers or partitions will rotate after the material enters and grade the material into different particle sizes or qualities. Due to different grading requirements, the angle requirements between the blades are different. Therefore, it is necessary to adjust the angle of the blades.

[0003] In the related art, during the operation of the grading wheel, the blades are generally fixedly connected to the wheel body by welding, and then connected to an external motor or other driving source through the wheel body, and the wheel body is driven to drive the blades to rotate, thereby performing the work.

[0004] However, during the current operation of the grading wheel, since the blades are installed by welding, it is difficult to adjust the angle of the blades according to the material grading requirements after the blades are installed. When the material grading requirements change, the user is required to disassemble and replace the entire grading wheel, which makes the use of the grading wheel more cumbersome and affects the adaptability and flexibility of the grading wheel.

[0036] Specifically, the working process or working principle of the adjustable grading wheel structure is as follows: during use, when the angle of the blade 2 cannot meet the grading requirements of the material and the inclination angle of the blade 2 needs to be changed, first, the screw handle 19 is held and rotated to cooperate with the screw hole 18 to apply an upward force to the clamping plate 15, so that the clamping plate 15 is separated from the clamping port 14 and enters the accommodating groove 17. At this time, the fixed column 16 provides stable support for the operation of the screw handle 19 and the screw hole 18, and then the adjusting ring 4 is held and driven to rotate the adjusting tooth 5. At this time, the connecting column 8 follows the gear 6 to rotate and applies a rotational tilting force to the blade 2, thereby changing the inclination angle of the blade 2 so that the inclination angle of the blade 2 is consistent with the material grading requirements. At the same time, the stabilizing column 13 follows the blade 2 to rotate inside the stabilizing groove 12 to adjust and stabilize the space between the blade 2 and the chassis 3. During this process, the rotating connecting column 10 moves inside the rotating connecting mouth 9 to cooperate with the rotating connecting disk 11, and performs rotational connection and anti-deviating work between the adjusting ring 4 and the top plate 1. At the same time, the angle slot 22 follows the adjusting ring 4 to rotate at the bottom of the reference frame 21. According to the change of the scale position between the reference frame 21 and the angle slot 22, the space adjustment ring 4 can change the actual angle of the blade 2 by adjusting the tooth 5 to drive the gear 6, so that the adjustment angle of the blade 2 can be more precise. After the inclination angle of the blade 2 is adjusted, the screw handle 19 is held and rotated to cooperate with the screw hole 18 to apply a downward force to the tightening disk 15, so that the tightening disk 15 moves downward, disengages from the accommodating groove 17, enters the tightening mouth 14, and contacts and tightens with the top of the top plate 1, and performs tightening and positioning work between the adjusting ring 4 and the top plate 1 to ensure the stability of the adjusting ring 4 and the blade 2 after adjustment.
