Description

Technical Field

[0001] This utility model belongs to the field of agricultural product processing machinery technology, and in particular relates to a centrifugal dehulling device for the initial processing of perilla seeds. Background Technology

[0002] During the deep processing of perilla seeds, their outer shell needs to be removed. Current shelling devices are mostly suitable for processing agricultural products with larger particle sizes. When processing small agricultural products like perilla seeds after adjusting the size of the processing position, jamming and clogging are very likely to occur. Moreover, shelling devices often have intricate and complex structures, making it difficult to clean when jamming and clogging occurs, which greatly affects the shelling process. Therefore, a shelling processing device that can adapt to small-particle agricultural products is needed to meet the needs of production and processing. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] A centrifugal dehulling device for primary processing of perilla seeds includes a support frame 1, a shelling roller 2, a shelling cylinder 3, a separation cylinder 4, a distribution hopper 5, and a blower 7. The separation cylinder 4 is fixedly mounted on the support frame 1. The shelling cylinder 3 is coaxially fixedly mounted on the top of the separation cylinder 4 and is connected to the separation cylinder 4. The shelling roller 2 is rotatably inserted into the shelling cylinder 3, and the top of the shelling roller 2 is suspended and connected to the top of the support frame 1. The distribution hopper 5 is fixedly mounted on the support frame 1 and is located below the discharge port at the lower end of the separation cylinder 4. The blower 7 is fixedly mounted on the outer wall of the distribution hopper 5, and the air outlet of the blower 7 is connected to the ventilation opening on the distribution hopper 5. The blower 7 operates to perform air separation on the mixture fed into the distribution hopper 5.

[0022] The support frame 1 has a horizontally fixed top support plate 12. Two hydraulic rods 13 are vertically fixed on the upper surface of the top support plate 12. The telescopic ends of the two hydraulic rods 13 are fixedly connected to the mounting plate 11. A drive motor is fixedly installed at the center of the lower surface of the mounting plate 11. The drive shaft of the drive motor is coaxially fixedly connected to the shaft 21 of the shelling roller 2. When the drive motor runs, it drives the shelling roller 2 to rotate in the shelling cylinder 3. The outer wall of the shelling roller 2 and the inner wall of the shelling cylinder 3 move relative to each other to crush the perilla seeds and perform shelling processing. The extension amount of the hydraulic rods 13 can be adjusted by adjusting the height of the mounting plate 11 to adjust the distance between the outer wall of the shelling roller 2 and the inner wall of the shelling cylinder 3 to adapt to the shelling processing of perilla seeds of different particle sizes.

[0023] The shell-breaking roller 2 includes a shaft 21, a crushing roller 22, a throwing plate 23, and multiple pushing blades 24. The shaft 21 is coaxially fixed on the crushing roller 22. The working section of the lower part of the crushing roller 22 is in the shape of an inverted frustum. The throwing plate 23 is circular and coaxially fixed on the lower end face of the crushing roller 22. The multiple pushing blades 24 are fixed on the upper surface of the throwing plate 23 and are evenly distributed around the axis of the shell-breaking roller 2.

[0024] The shell-breaking cylinder 3 has an inverted conical wall with the same inclination as the working section of the crushing roller 22. A through hole is opened at the lower tip of the shell-breaking cylinder 3 to connect with the separating cylinder 4. The working section of the shell-breaking roller 2 is located in the shell-breaking cylinder 3. The throwing plate 23, carrying multiple throwing blades 24, is located in the separating cylinder 4. After being crushed in the shell-breaking cylinder 3, the perilla seeds slide down the inner wall of the shell-breaking cylinder 3 onto the throwing plate 23. The shell-breaking cylinder 3 continues to rotate, throwing the crushed perilla seeds toward the inner wall of the separating cylinder 4. The shells of the crushed perilla seeds are broken by impact when they hit the inner wall of the separating cylinder 4.

[0025] The separating cylinder 4 includes a cylindrical cylinder 41 and a conical hopper 42. The cylindrical cylinder 41 is cylindrical and coaxially fixedly connected to the shell-breaking cylinder 3. The conical hopper 42 is integrally fixedly connected to the open end of the lower end of the cylindrical cylinder 41. The discharge port at the lower end of the conical hopper 42 narrows into a long strip and becomes a flat mouth. The ventilation port of the separating hopper 5 connected to the blower 7 is opened on the side wall parallel to the length direction of the discharge port.

[0026] The lower end of the distribution hopper 5 is provided with a first discharge hopper 51 and a second discharge hopper 52. An inclined distribution plate 53 is fixedly arranged between the first discharge hopper 51 and the second discharge hopper 52. The first discharge hopper 51 is located below the discharge port of the cone hopper 42, and the second discharge hopper 52 is located on the side of the first discharge hopper 51 away from the ventilation port. Discharge ports are opened below the first discharge hopper 51 and the second discharge hopper 52. Collection boxes are movably connected below the two discharge ports. When the fan 7 operates, it blows air into the distribution hopper 5 through the ventilation port. The mixed shelled perilla seeds and perilla seed shells fall from the discharge port and are separated by the airflow blown by the fan 7. The shelled perilla seeds fall into the first discharge hopper 51, and the perilla seed shells are blown and fall into the second discharge hopper 52.

[0027] The centrifugal dehulling equipment for primary processing of perilla seeds also includes a cleaning component 6. A circular hoisting track 14 is fixedly mounted on the top of the support frame 1. A hanging slider 15 is slidably installed on the hoisting track 14. The cleaning component 6 is fixedly hoisted onto the bottom surface of the hanging slider 15. The position of the cleaning component 6 can be adjusted by dragging the hanging slider 15 along the hoisting track 14. The hoisting track 14 is designed as an inverted T-shape, and the hanging slider 15 has a hanging groove that matches the hoisting track 14.

[0028] The cleaning assembly 6 includes an air pump assembly 61, an air supply pipe 62, and a jet nozzle 63. The air pump assembly 61 is fixedly mounted on the mounting slider 15. The air pump assembly 61 integrates an air pump and a winding device. The air supply pipe 62 is wound around the winding device. One end of the air supply pipe 62 is connected to the air outlet of the air pump, and the jet nozzle 63 is fixedly installed on the other end of the air supply pipe 62. Pulling the lower end of the air supply pipe 62 extends the jet nozzle 63 so that it is inserted between the shell-breaking roller 2 and the shell-breaking cylinder 3. The air pump operates to supply air, causing the airflow to be sprayed out from the jet nozzle 63 to clean the outer wall of the shell-breaking roller 2 and the inner wall of the shell-breaking cylinder 3. During the cleaning process, the position of the mounting slider 15 can be adjusted arbitrarily to ensure thorough and comprehensive cleaning. After cleaning is completed, the air pump is turned off and the winding device is started to wind the air supply pipe 62.

[0029] The upper end of the shelling cylinder 3 is provided with an outward inclined edge, and the outer edge of the upper end of the shelling roller 2 is provided with an inward inclined edge. The inward inclined edge and the outward inclined edge cooperate to form a feeding port. The perilla seeds to be shelled are added into the equipment through the feeding port for shelling processing.

[0030] The outer wall of the working section of the shell-breaking roller 2 and the inner wall of the shell-breaking cylinder 3 are both made of frosted surface to increase friction and improve the crushing effect.

[0031] Working principle: Before shelling, the extension of the hydraulic rod 13 is adjusted, thereby adjusting the distance between the outer wall of the shelling roller 2 and the inner wall of the shelling cylinder 3 to match the particle size of the perilla seeds to be processed and ensure the best shelling effect.

[0032] During the shelling process, the perilla seeds to be shelled are put into the shelling cylinder 3. The drive motor is started to drive the shelling roller 2 to rotate and crush the perilla seeds. After being crushed, the perilla seeds fall onto the throwing plate 23 and are thrown against the inner wall of the separating cylinder 4 as they rotate. The crushed perilla seed shells will be broken under the impact. The mixture of shelled perilla seeds and perilla seed shells falls from the discharge port of the cone hopper 42 into the distribution hopper 5 for air separation. The shelled perilla seeds after air separation fall into the collection box.

[0033] Unshelled perilla seeds may be mixed in with the shelled perilla seeds collected in the collection box. Color sorting equipment can be used to sort the mixture, and then the unshelled perilla seeds can be shelled again.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
