Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, and in particular to a sorting roller device for a wheat seed color sorter. Background Technology

[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology.

[0003] Currently, existing sorting roller devices (such as patent publication number: CN220004950U) disclose a sorting device for a color sorter. The good product hopper receives the good product material after color sorting, the guide plate and the discharge hopper conduct the material, and the screening component receives the material and screens it. The material is screened according to the size set by the screen cylinder. The screened material falls into the storage hopper in grades, realizing screening in the discharge process of the color sorter, improving screening efficiency, and eliminating the need for further screening by a screening machine.

[0004] In the aforementioned patent, the diameter of the sorting roller cannot be changed. With a fixed diameter, increasing the seed feed rate leads to insufficient sorting of some seeds and a decrease in accuracy. If the speed is reduced to ensure accuracy, the processing efficiency is greatly reduced, and it is difficult to balance sorting speed and accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sorting roller device for a wheat seed color sorter, which solves the technical problem that the diameter of the sorting roller cannot be changed. With a fixed diameter, increasing the seed feed rate leads to insufficient sorting of some seeds and a decrease in accuracy. If the speed is reduced to ensure accuracy, the processing efficiency is greatly reduced, and it is difficult to balance sorting speed and accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sorting roller device for a wheat seed color sorter includes a shell, a support cylinder and a protective plate. Multiple support seats are fixedly installed on the outer side of the protective plate, and guide rails are slidably installed on the side ends of the protective plate. Drive screws are rotatably installed inside the guide rails.

[0008] The surface of each protective plate is provided with multiple silicone soft strips, and a sieve plate is fixedly installed at the top of each silicone soft strip. A linear slide plate is slidably installed at the side end of each sieve plate, and two buffer rods are fixedly installed at the bottom end of the linear slide plate.

[0009] Preferably, a mounting cylinder is fixedly installed on the side end of the guard plate, and a limit module is provided inside the mounting cylinder;

[0010] The limiting module has clamping bars slidably installed on both sides, and each clamping bar has an electric push rod at its end.

[0011] Preferably, a stabilizing ring is fixedly installed on the surface of the guide rail plate, and the surface of the stabilizing ring has a raised structure;

[0012] Multiple pivot seats are fixedly installed on the surface of the guide rail plate, and the end of the guide rail plate has a groove structure, and the end of the guide rail plate is connected to the limiting module.

[0013] Each of the aforementioned hub seats has a diagonal brace rotatably mounted inside, the top of which is rotatably connected to the linear slide plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects;

[0015] In this invention, the pivot seat pulls the inclined support rod, causing the linear slide plate to slide inward at the top of the support seat. When the linear slide plate slides, it squeezes the buffer rod to extend and retract, while simultaneously causing one end of the screening plate to contract. The screening plate squeezes the outer silicone soft strip to deform it, ultimately achieving the adjustment of the drum diameter to meet the seed screening needs of different feed amounts.

[0016] In this invention, the stabilizing ring fixedly installed on the surface of the guide rail plate has a raised structure. When the guide rail plate slides, it will drive the stabilizing ring to slide synchronously inside the mounting cylinder. The stabilizing ring is connected to the inner wall of the mounting cylinder, which can not only increase the stability of the sliding process, but also prevent the guide rail plate from shaking. When the linear slide plate slides, it will squeeze the buffer rod to extend and retract. The buffer rod can play a buffering role during the adjustment process, reducing the hard impact between components. Attached Figure Description

[0023] This application provides a sorting drum device for a wheat seed color sorter, effectively solving the problem that the diameter of the sorting drum cannot be changed. With a fixed diameter, increasing the seed feed rate leads to insufficient sorting of some seeds and a decrease in accuracy. If the speed is reduced to ensure accuracy, the processing efficiency is greatly reduced, and it is difficult to balance sorting speed and accuracy. By pulling the inclined support rod through the pivot seat, the linear slide plate slides inward at the top of the support seat. When the linear slide plate slides, it squeezes the buffer rod to extend and retract, and at the same time drives one end of the screening plate to contract. The screening plate squeezes the outer silicone soft strip to deform it, and finally realizes the adjustment of the drum diameter to adapt to the seed screening requirements of different feed rates.

[0024] Example

[0025] like Figures 1-4 As shown, the technical solution in this embodiment effectively solves the problem that the diameter of the sorting roller cannot be changed. Under a fixed diameter, increasing the seed feed rate leads to insufficient sorting of some seeds and a decrease in accuracy; if the speed is reduced to ensure accuracy, the processing efficiency is greatly reduced, and it is difficult to balance sorting speed and accuracy. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a sorting drum device for a wheat seed color sorter, including a housing 11, a support cylinder 12, and a protective plate 13. Multiple support seats 18 are fixedly installed on the outer side of the protective plate 13, and guide rail plates 23 are slidably installed on the side end of the protective plate 13. Drive screws 27 are rotatably installed inside the guide rail plates 23. The support cylinder 12 is rotatably connected to the housing 11 and provides support for the protective plate 13. At the same time, another set of protective plates 13 is provided with an opening, through which wheat seeds enter the inside of the drum. By driving the support cylinder 12 to rotate, the support cylinder 12 adjusts the entire protective plate 13 to rotate, thus rotating and screening the wheat seeds inside. The end of the drive screw 27 is connected to an output motor. The forward-rotating drive screw 27 exerts a force on the guide rail plate 23, causing the guide rail plate 23 to slide inside the mounting cylinder 19. The guide rail plate 23 slides towards the support cylinder 12, pulling the end of the diagonal brace 26 and exerting a downward force on the linear slide plate 16.

[0027] The surface of the guard plate 13 is provided with multiple silicone soft strips 14. A sieve plate 15 is fixedly installed at the top of each silicone soft strip 14. A linear slide plate 16 is slidably installed at the side end of each sieve plate 15. Two buffer rods 17 are fixedly installed at the bottom end of the linear slide plate 16. The silicone soft strips 14 are made of soft material and can be bent and deformed. By pulling the diagonal support rod 26, the linear slide plate 16 slides synchronously at the top of the support base 18. The linear slide plate 16 slides into the support base 18, squeezing the two buffer rods 17 to extend and retract. At the same time, the linear slide plate 16 drives one end of the sieve plate 15 to contract. The sieve plate 15 squeezes the outer silicone soft strip 14, causing the silicone soft strip 14 to deform and adjust the diameter of the roller.

[0028] A mounting cylinder 19 is fixedly installed on the side end of the guard plate 13. A limit module 21 is provided inside the mounting cylinder 19. The guide plate 23 slides inside the mounting cylinder 19, and the end of the guide plate 23 is connected to the limit module 21.

[0029] Both sides of the limiting module 21 are slidably mounted with clamping strips 22, and each clamping strip 22 is provided with an electric push rod at the end. When the guide rail plate 23 stops sliding inside the mounting cylinder 19, the electric push rod squeezes the clamping strip 22 to move, so that the clamping strip 22 slides and squeezes the end of the guide rail plate 23 to fix the position of the guide rail plate 23.

[0030] A stabilizing ring 24 is fixedly installed on the surface of the guide rail plate 23. The surface of the stabilizing ring 24 has a raised structure. When the guide rail plate 23 slides, it drives the stabilizing ring 24 to slide inside the mounting cylinder 19. The stabilizing ring 24 is in contact with the inner wall of the mounting cylinder 19, which increases the stability of the sliding and can prevent the guide rail plate 23 from shaking.

[0031] Multiple pivot seats 25 are fixedly installed on the surface of the guide rail plate 23. The end of the guide rail plate 23 has a groove structure and the end of the guide rail plate 23 is connected to the limiting module 21. When the guide rail plate 23 slides, it generates a thrust on the end of the diagonal brace 26, causing the diagonal brace 26 to rotate and swing inside the pivot seat 25. At the same time, the linear slide plate 16 at the top of the support seat 18 generates a diagonal pull force, causing the linear slide plate 16 to slide synchronously along the top of the support seat 18.

[0032] Each hub seat 25 has a diagonal brace 26 rotatably mounted inside, and the top of the diagonal brace 26 is rotatably connected to the linear slide plate 16.

[0033] Working principle:

[0034] The first step involves the outer shell 11, which has a structure similar to a combination of a funnel and a cylinder, providing external protection and space for the entire sorting drum device. The support cylinder 12 is rotatably connected to the outer shell 11 and serves as a support structure for the guard plate 13. A set of guard plates 13 has openings for materials to enter the drum. When the support cylinder 12 is driven to rotate, it drives the guard plate 13 to rotate as a whole. The silicone soft strip 14, the sieve plate 15, and other components on the surface of the guard plate 13 rotate accordingly, performing rotational sieving of the wheat seeds inside. By utilizing the interaction between the various components and the seeds during the rotation process, the initial sorting operation is achieved.

[0035] The end of the drive screw 27 is connected to the output motor. When the output motor drives the drive screw 27 to rotate in the forward direction, the drive screw 27 exerts a force on the guide rail plate 23, causing the guide rail plate 23 to slide inside the mounting cylinder 19. During the sliding process of the guide rail plate 23 towards the support cylinder 12, the pivot seat 25 on its surface drives the end of the diagonal brace 26 to move, generating a diagonal pulling force on the linear slide plate 16. Under the action of the diagonal pulling force of the diagonal brace 26, the linear slide plate 16 slides towards the inside of the support seat 18 at the top of the support seat 18. During the sliding process, it squeezes the two buffer rods 17 to extend and retract. At the same time, the linear slide plate 16 drives one end of the screening plate 15 to contract. The screening plate 15 squeezes the outer silicone soft strip 14. Since the silicone soft strip 14 is a soft material that can be bent and deformed, the diameter of the drum can be adjusted to adapt to different sorting requirements.

[0036] In the second step, the guide rail plate 23 slides inside the mounting cylinder 19, and its end engages with the limiting module 21. When the guide rail plate 23 slides to the required position and stops, the electric push rods on both sides of the limiting module 21 are activated, and the clamping strip 22 moves. The clamping strip 22 slides and squeezes the end of the guide rail plate 23, thereby fixing the position of the guide rail plate 23 and ensuring the structural stability after the roller diameter is adjusted.

[0037] A stabilizing ring 24 with a raised structure is fixedly installed on the surface of the guide rail plate 23. When the guide rail plate 23 slides inside the mounting cylinder 19, the stabilizing ring 24 slides synchronously inside the mounting cylinder 19. The stabilizing ring 24 is connected to the inner wall of the mounting cylinder 19, which increases the stability of the guide rail plate 23 during the sliding process, effectively prevents the guide rail plate 23 from shaking, and ensures the stable operation of the entire diameter adjustment and screening process.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
