Specifically, a bearing is fixedly connected to the outer wall of the bottom end of the discharge pipe, and the movable cylinder is rotatably connected to the bottom end of the discharge pipe through the bearing, so that starch can be input into the interior of the movable cylinder while ensuring effective rotation of the movable cylinder.

[0009] Preferably, the support shafts are distributed at equal angles along the axial centerline of the movable cylinder, and the crushing blades form a linkage structure with the movable conical wheel through the support shafts. Specifically, there is a gap between the crushing blades, so as to ensure that the crushing blades are driven to rotate through the support shafts when the movable conical wheel rotates.

[0010] Preferably, the movable cone wheel meshes with the fixed cone wheel, and the movable cone wheel and the fixed cone wheel form a rotating structure, which facilitates the rotation of the movable cone wheel while it revolves around the fixed cone wheel, thereby facilitating the subsequent crushing work.

[0011] Preferably, the inner wall of the fixed cone wheel is provided with a bearing, and the movable cylinder is connected to the fixed cone wheel through the bearing, thereby facilitating effective support for the movable cylinder.

[0022] Please see Figure 1-4This utility model provides a technical solution: a crushing and screening machine for starch processing, including a device housing 1, a fixed bracket 2 fixedly connected to the outer wall of the device housing 1, a drive motor 3 fixedly connected to one side of the device housing 1, a discharge pipe 11 fixedly connected to the other side of the device housing 1, a feed bin 9 fixedly connected to the top of the device housing 1, a drive shaft 4 fixedly connected to the output shaft of the drive motor 3 via a coupling, a driving sun gear 5 fixedly connected to one end of the drive shaft 4, a driven planetary gear 6 provided on the outer wall of the driving sun gear 5, a movable gear ring 7 provided on the outer wall of the driven planetary gear 6, a movable cylinder 8 fixedly connected to the inner wall of the movable gear ring 7, a screening baffle 10 fixedly connected to one end of the movable cylinder 8, a support shaft 12 movably connected to the inner wall of the movable cylinder 8, a crushing blade 13 fixedly connected to one end of the support shaft 12, and a crushing blade 13 fixedly connected to the other end of the support shaft 12. A movable conical wheel 14 is fixedly connected to the end of the device, and a fixed conical wheel 15 is fixedly connected to the inner wall of the device housing 1. By setting up the device housing 1, fixed support 2, drive motor 3, drive shaft 4, active sun gear 5, driven planetary gear 6, movable gear ring 7, movable cylinder 8, feed bin 9, screening baffle 10 and discharge pipe 11, it is convenient to drive the movable cylinder 8 to rotate, so that the movable cylinder 8 drives the starch to roll inside, thereby making the starch more uniformly crushed and solving the problem of uneven crushing that affects processing efficiency. At the same time, by setting up the support shaft 12, crushing blade 13, movable conical wheel 14 and fixed conical wheel 15, it is convenient for the movable cylinder 8 to drive the crushing blade 13 to rotate automatically during the rotation, so that the starch crushing work does not require additional energy drive, which helps to reduce processing costs.

[0023] Preferably, the driving sun gear 5 meshes with the driven planet gear 6, and the driven planet gear 6 meshes with the movable gear ring 7. Specifically, there is a gap between the driving sun gear 5 and the driven planet gear 6, and the driven planet gear 6 is symmetrically distributed among the driving sun gears 5. The driven planet gear 6 is rotatably connected to the inner wall of the device housing 1 through a shaft, which facilitates the driving sun gear 5 to drive the driven planet gear 6 to rotate, so that the driven planet gear 6 drives the movable gear ring 7 to rotate, which in turn facilitates the rotation of the movable cylinder 8, so that the movable cylinder 8 drives the starch to roll.

[0024] Preferably, the inner wall of the movable cylinder 8 is cone-shaped, and the screening baffle 10 is set at the longer end of the feed hopper 9. Specifically, the movable cylinder 8 and the device housing 1 form a rotating structure, which facilitates the sliding of one end of the starch screening baffle 10 during the rotation of the movable cylinder 8.

[0025] Preferably, the bottom of the discharge pipe 11 is L-shaped, and one end of the bottom of the discharge pipe 11 extends into the interior of the movable cylinder 8. Specifically, a bearing is fixedly connected to the outer wall of the bottom end of the discharge pipe 11, and the movable cylinder 8 is rotatably connected to the bottom end of the discharge pipe 11 through the bearing, so that starch can be input into the interior of the movable cylinder 8 while ensuring the effective rotation of the movable cylinder 8.

[0026] Preferably, the support shaft 12 is distributed at equal angles along the axial centerline of the movable cylinder 8, and the crushing blade 13 forms a linkage structure with the movable cone wheel 14 through the support shaft 12. Specifically, there is a gap between the crushing blades 13, so as to ensure that when the movable cone wheel 14 rotates, it drives the crushing blades 13 to rotate through the support shaft 12.

[0027] Preferably, the movable cone wheel 14 meshes with the fixed cone wheel 15, and the movable cone wheel 14 and the fixed cone wheel 15 form a rotating structure, which facilitates the rotation of the movable cone wheel 14 as it revolves around the fixed cone wheel 15, thereby facilitating the subsequent crushing work.

[0029] In operation, starch is first fed into the movable cylinder 8 through the feed hopper 9. Then, the drive motor 3 is started, causing the drive shaft 4 to rotate. The drive shaft 4 then rotates the active sun gear 5, which in turn rotates the driven planetary gear 6. The driven planetary gear 6 then rotates the movable gear ring 7, which in turn rotates the movable cylinder 8. This causes the starch inside the movable cylinder 8 to roll, which facilitates more uniform crushing. Furthermore, the conical shape of the inner wall of the movable cylinder 8 allows the starch to gradually approach the screening baffle 10 for screening. Simultaneously, as the movable cylinder 8 rotates, the support shaft 12 drives the movable cone wheel 14 to rotate around the fixed cone wheel 15. The movable cone wheel 14 rotates on its own axis while revolving around the fixed cone wheel 15, which in turn drives the crushing blades 13 to rotate via the support shaft 12. The crushing blades 13 then crush the starch. The entire structure is driven by a single motor, which helps to achieve energy-saving and environmentally friendly effects.
