DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a driving mechanism for rotating a disc distributor.

[0031] Reference Figure 1-3 The driving mechanism for the rotation of the disc feeder includes a driving motor, a transmission assembly 2, a limit assembly 3, and a support assembly 4. In this embodiment, the driving motor is not shown. The transmission assembly 2 includes a pin gear 21 and a pin wheel 22. The output shaft of the driving motor is coaxially connected to the pin gear 21 through a reducer 5. The output shaft of the driving motor is coaxially connected to the input shaft of the reducer 5. The pin gear 21 is coaxially connected to the output shaft of the reducer 5. The pin wheel 22 is coaxially connected to the outer peripheral side wall of the storage hopper 1. The pin wheel 22 and the pin gear 21 are meshed.

[0032] The cooperation of the pin gear 21 and the pin wheel 22 improves the smoothness of the transmission between the drive motor and the storage hopper 1, making it difficult for the storage hopper 1 to get stuck during operation, thereby improving the feeding efficiency of the disc feeder. Moreover, after long-term use, the pin teeth of the pin wheel 22 can be replaced separately, while the bevel gear and bevel gear ring need to be replaced as a whole. The production and maintenance costs of the pin gear transmission are more economical than those of the bevel gear transmission.

[0033] The limiting assembly 3 is located on the side of the storage hopper 1 away from the transmission assembly 2 in the width direction, that is, the limiting assembly 3 is located on the inner circumference side of the storage hopper 1 , and six groups of limiting assemblies 3 are equidistantly arranged along the circumference of the storage hopper 1 .

[0034] The limiting assembly 3 includes a fixing frame 31 and a limiting wheel 32. The fixing frame 31 is fixed on the top surface of the silo. The limiting wheel 32 is rotatably connected to the top surface of the fixing frame 31. The central axis of the limiting wheel 32 is vertically arranged. A limiting guide rail 33 is arranged on the peripheral side wall of the storage hopper 1. The peripheral side wall of the limiting wheel 32 abuts against the peripheral side wall of the limiting guide rail 33. Both sides of the limiting wheel 32 in the vertical direction are coaxially connected to the limiting retaining ring 321. The sides of the limiting retaining ring 321 that are close to each other are in contact with the two sides of the limiting guide rail 33 in the vertical direction.

[0035] The radial and axial displacements of the storage hopper 1 are limited by the cooperation of the limiting wheel 32 and the limiting guide rail 33, thereby improving the stability of the material distributor during operation, thereby improving the material distribution effect of the disc material distributor. Rolling friction is generated between the outer peripheral wall of the limiting wheel 32 and the inner peripheral wall of the storage hopper 1, thereby ensuring the smoothness of the rotation of the storage hopper 1.

[0036] The support assembly 4 is used to support the storage hopper 1 to rotate. The support assembly 4 includes a support wheel group 41 and a support track 42. The support wheel group 41 is arranged at the bottom of the storage hopper 1. Multiple groups of support wheel groups 41 are evenly arranged on both sides of the radial direction of the storage hopper 1 to improve the uniformity of the support force provided by the support wheel group 41 to the storage hopper 1. The support track 42 is annular and fixedly arranged on the top surface of the silo.

[0037] Each group of supporting wheel groups 41 includes two running wheels 411. The two running wheels 411 in the same group are respectively located on the inner and outer sides of the storage hopper 1. The two running wheels 411 in the same group are coaxially connected through a connecting shaft 412. Both ends of the connecting shaft 412 pass through the corresponding running wheels 411 and are connected to a fixing plate 413. The connecting shaft 412 is fixedly connected to the outer wall of the storage hopper 1 through the fixing plate 413, and the running wheels 411 are rotatably connected to the corresponding connecting shaft 412.

[0038] The support track 42 is also arranged on the inner and outer sides of the storage hopper 1. The running wheels 411 on the inner side of the storage hopper 1 move on the support track 42 on the inner side of the storage hopper 1 at the same time, and the running wheels 411 on the outer side of the storage hopper 1 move on the support track 42 on the outer side of the storage hopper 1 at the same time.

[0039] The cooperation between the supporting wheel set 41 and the supporting track 42 enables the storage hopper 1 to rotate more stably, further improving the material distribution effect of the disc material distribution machine.

[0040] The implementation principle of the driving mechanism for rotating the disc feeder in the embodiment of the present application is as follows:

[0041] The driving motor drives the pin gear 21 to rotate through the reducer 5, and the pin gear 21 drives the pin wheel 22 to rotate, thereby driving the storage hopper 1 to rotate. During the rotation of the storage hopper 1, the limiting wheel 32 abuts against the inner wall of the storage hopper 1 to limit the position, so that the storage hopper 1 can run stably.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
