Description

Technical Field

[0001] The present invention relates to the technical field of shelling equipment, and specifically relates to a centrifugal shelling equipment and method. Background Art

[0002] Cereals cover a wide range, including rice, wheat, millet, soybeans, etc. They are mainly plant seeds and fruits. After being ground into flour, they can be used to make foods such as bread, steamed buns, biscuits, and noodles. A cereal grinding device is a mechanical equipment used to grind cereals into powder or granular materials. The cereals are ground into the required powder or granular materials by means of tool rotation or friction. The purpose is to process the cereals into a form suitable for consumption or processing for subsequent food processing or production.

[0003] Although the existing cereal shelling equipment in the prior art can achieve the shelling operation of various cereals, there are still some disadvantages. Especially when shelling mixed cereals, a large amount of cereals are usually directly poured into the shelling equipment all at once. Due to the different diameters of the mixed cereals, it is difficult for the shelling mechanism in the shelling equipment to adapt to cereals of different diameters simultaneously (for example, cereals with smaller diameters will pass through the gap formed between the tool during shelling and the inner wall of the shelling cylinder), resulting in insufficient shelling. This will affect the purity and quality of the product. Especially in high - requirement processing industries, the conventional method is to adjust the shelling intensity of the shelling equipment to re - perform the shelling treatment, which increases the production cost and processing time. Moreover, cereals with larger diameters will also be crushed during the re - shelling process, resulting in the loss of the nutritional value of the cereals. To solve the above problems, a centrifugal shelling equipment and method are proposed. Summary of the Invention

Although it can achieve the shelling operation of various cereals, there are still some disadvantages. Especially when shelling mixed cereals, a large amount of cereals are usually directly poured into the shelling equipment all at once. Due to the different diameters of the mixed cereals, it is difficult for the shelling mechanism in the shelling equipment to adapt to cereals of different diameters simultaneously (for example, cereals with smaller diameters will pass through the gap formed between the tool during shelling and the inner wall of the shelling cylinder), resulting in insufficient shelling. This will affect the purity and quality of the product. Especially in high - requirement processing industries, the conventional method is to adjust the shelling intensity of the shelling equipment to re - perform the shelling treatment, which increases the production cost and processing time. Moreover, cereals with larger diameters will also be crushed during the re - shelling process, resulting in the loss of the nutritional value of the cereals.

A spiral feeding sheet in a spiral shape is fixedly connected inside the sorting cylinder. A first through groove, a second through groove, and a third through groove are penetrated from right to left on the outer surface of the sorting cylinder. The size of the first through groove is smaller than that of the second through groove. The size of the second through groove is smaller than that of the third through groove.

[0014] Preferably, the shelling assembly includes two fixing bars which are respectively fixedly connected to the sides of the two support rods.

A discharge port is arranged at the lower end of one side of the pneumatic separation cylinder close to the centrifugal fan, and a shell discharge port is arranged at the upper end of the other side of the pneumatic separation cylinder far from the centrifugal fan.

[0017] A usage method of a centrifugal shelling device for implementing the above-mentioned centrifugal shelling device includes the following steps:

[0018] S1: First, power on the lifting motor, servo motor, driving motor and centrifugal fans. Then pour grains into the storage cylinder. Next, the lifting motor drives the first bevel gear to rotate, which drives the second bevel gear to rotate through the meshing relationship, thereby realizing the rotation of the threaded rod and then making the moving block move upward through the threaded fit relationship to lift the grains. After the storage cylinder reaches the highest point, the output end of the air cylinder extends to push the push block to slide upward along the guiding slide rail, and the connecting rod is used to push the turning plate to rotate around the rotating shaft, causing the storage cylinder to tilt and pour the grains inside the storage cylinder into the feeding hopper;

[0019] S2: The feeding hopper imports the grains into the sorting cylinder. Then, the output end of the servo motor drives the driving gear to rotate. Due to the meshing relationship between the driving gear and the driving gear ring, the sorting cylinder can rotate between the rotating guide wheels. When the sorting cylinder rotates, the internal spiral feeding sheet transports the grains from the right side to the left side. During the transportation process, grains of different sizes are screened into the guide trough through the first through groove, the second through groove, and the third through groove. Grains of different sizes enter the hulling assembly through the guide trough.

[0020] S3: Grains of different sizes enter different chambers separated by the blocking plate in the hulling cylinder. Then, the output end of the driving motor drives the driving pulley to rotate. Through the belt and the driven pulley, the main shaft rotates. When the main shaft rotates, the connecting rod drives the extrusion plate to rotate. The grains are hulled by the extrusion between the extrusion plate and the hulling cylinder.

[0021] S4: After hulling, the grains enter the air separation cylinder through the holes at the bottom of the hulling cylinder. At this time, the centrifugal fan works to blow air into the air separation cylinder. Since the weight of the grain husk is less than that of the grain endosperm, under the action of the airflow, the grain husks will be discharged through the shell discharge port, while the heavier endosperm will leak out from the discharge port through the inclined bottom surface of the air separation cylinder under the action of gravity.

[0022] Compared with the prior art, the advantages of the present invention are as follows: By setting the rotation of the threaded rod, the moving block moves upward through the threaded fit relationship to lift the grains. After the storage cylinder reaches the highest point, the output end of the cylinder extends to push the push block to slide upward along the guiding slide rail. Through the connecting rod, the turning plate is pushed to rotate around the rotating shaft, causing the storage cylinder to tilt, and the grains inside the storage cylinder are poured into the sorting cylinder. When the sorting cylinder rotates with the servo motor as the power source, the grain particles are divided into three different specifications of large, medium, and small through the first through groove, the second through groove, and the third through groove. Grains of different sizes enter the hulling assembly through the guide trough and are hulled in the area separated by the blocking plate. After the hulling process, the grains are screened under the airflow blown by the centrifugal fan. The grain husks will be discharged through the shell discharge port, while the heavier endosperm will leak out from the discharge port through the inclined bottom surface of the air separation cylinder under the action of gravity. Through sorting, different specifications of grains are processed separately. This precise adaptation can significantly improve the hulling efficiency, avoid over - processing or under - processing situations. At the same time, it can not only improve the hulling efficiency, but also reduce the residue of the husk, improve the purity and cleanliness of the grains. During the hulling process of mixed - specification grains, the mixing of smaller and larger grains together will cause the equipment to bear uneven pressure, resulting in excessive wear. Through sorting, it can ensure that each specification of grain is processed in a suitable way, thereby slowing down the wear of the equipment and extending the service life of the equipment.

On the surfaces of the two guide rails 209, a pushing block 210 is slidably connected through a sliding block. On one side of the two pushing blocks 210 away from the guide rails 209, a connecting rod 213 is rotatably connected. The upper ends of the two connecting rods 213 are rotatably connected to the bottom of the turning plate 212. At the corresponding positions of the bottom of the moving seat 208 and the two pushing blocks 210, air cylinders 211 are fixedly installed.

Two limiting columns 217 are also fixedly connected to the bottom of the moving seat 208. The setting of the turning plate 212 and the air cylinder 211 enables the storage cylinder 216 to automatically turn over and pour grains, realizing the function of automatic feeding and improving the automation degree of the equipment.

[0048] Refer to Figure 7 - Figure 8As shown in the figure, the sorting component 3 includes two sets of mounting brackets 301 and a sorting cylinder 307. The two sets of mounting brackets 301 are respectively fixedly connected to the upper ends of the two support rods 1. The sorting cylinder 307 is rotatably connected above the rotating guide wheel 306. Inside the sorting cylinder 307, a spiral feeding piece 309 in a spiral shape is fixedly connected. On the outer surface of the sorting cylinder 307, a first through groove 310, a second through groove 311, and a third through groove 312 are penetrated from right to left. The size of the first through groove 310 is smaller than that of the second through groove 311, and the size of the second through groove 311 is smaller than that of the third through groove 312. At least one side of the mounting bracket 301 is internally fixedly connected with a feeding hopper 302, and the bottom of the feeding hopper 302 extends into the sorting cylinder 307.

[0050] Refer to Figure 9 - Figure 11 As shown in the figure, the hulling component 6 includes two sets of fixing bars 601. The two sets of fixing bars 601 are respectively fixedly connected to the sides of the two support rods 1. A hulling cylinder 602 is fixedly connected between the two sets of fixing bars 601. Inside the hulling cylinder 602, a blocking plate 604 corresponding to the positions of the two partition plates 5 is fixedly connected. The setting of the blocking plate 604 further divides the hulling cylinder 602 into different chambers, avoiding the mutual influence of grains of different sizes during the hulling process. Inside the hulling cylinder 602, a main shaft 603 is rotatably connected. The right end of the main shaft 603 passes through the right side wall of the hulling cylinder 602 and is fixedly connected with a driven pulley 607. A wind selection cylinder 612 is fixedly connected to the bottom of the hulling cylinder 602. Inside the wind selection cylinder 612, a partition plate corresponding to the positions of the two partition plates 5 is also fixedly connected. It should be noted that holes adapted to the first through groove 310, the second through groove 311, and the third through groove 312 are opened at the bottom of the hulling cylinder 602, so that the materials after hulling can smoothly enter the wind selection cylinder 612.

[0051] Refer to Figure 9 - Figure 11As shown, the shelling assembly 6 further includes two sets of fixing frames 608, which are respectively fixedly connected to the front sides of the two sets of support rods 1. An installation plate 609 is fixedly connected between the two sets of fixing frames 608. At least three centrifugal fans 613 are fixedly installed on the upper surface of the installation plate 609. The output ends of the three centrifugal fans 613 are connected to the air separation cylinder 612 through pipelines. A driving motor 610 is fixedly installed on the upper right side of the upper surface of the installation plate 609. The output end of the driving motor 610 is fixedly connected to a driving pulley 611. The driving pulley 611 is in transmission connection with a driven pulley 607 through a belt.

[0052] Referring to Figure 9 - Figure 11 As shown, connecting rods 605 are fixedly connected to the left end, middle and right end of the outer surface of the main shaft 603. The ends of the connecting rods 605 are fixedly connected to pressing plates 606. A discharge port 614 is arranged at the lower end of one side of the air separation cylinder 612 close to the centrifugal fan 613. A shell discharge port 615 is arranged at the upper end of the other side of the air separation cylinder 612 far from the centrifugal fan 613. The distances between the pressing plates 606 in different regions and the inner wall of the shelling cylinder 602 are different. For example, the distance between the pressing plate 606 under the third through groove 312 and the inner wall of the shelling cylinder 602 is greater than the distance between the pressing plate 606 under the second through groove 311 and the inner wall of the shelling cylinder 602. Similarly, it can be known that the distance between the pressing plate 606 under the second through groove 311 and the inner wall of the shelling cylinder 602 is greater than the distance between the pressing plate 606 under the first through groove 310 and the inner wall of the shelling cylinder 602. The combination of the air separation cylinder 612 and the centrifugal fan 613 can separate the two according to the weight difference between the grain shell and the endosperm, realizing the further purification of the grain.

[0053] The present invention also designs a use method of a centrifugal shelling device, including the following steps:

[0054] S1: First, power on the lifting motor 205, the servo motor 304, the driving motor 610 and the centrifugal fan 613. Then pour grains into the storage cylinder 216. Then the lifting motor 205 drives the first bevel gear 206 to rotate, drives the second bevel gear 207 to rotate through the meshing relationship, thereby realizing the rotation of the threaded rod 204, and then making the moving block 215 move upward through the threaded cooperation relationship to lift the grains. After the storage cylinder 216 reaches the highest point, the output end of the cylinder 211 extends to push the push block 210 to slide upward along the guiding slide rail 209, and pushes the turning plate 212 to rotate around the rotating shaft 214 through the connecting rod 213, so that the storage cylinder 216 tilts, and the grains inside the storage cylinder 216 are poured into the feeding hopper 302.

[0055] S2: The hopper 302 feeds the grains into the sorting cylinder 307. Then, the output end of the servo motor 304 drives the driving gear 305 to rotate. Due to the meshing relationship between the driving gear 305 and the driving gear ring 308, the sorting cylinder 307 can rotate between the rotating guide wheels 306. When the sorting cylinder 307 rotates, the spiral feeding blade 309 inside transports the grains from the right side to the left side. During the transportation process, grains of different sizes are screened into the guide trough 4 through the first through groove 310, the second through groove 311, and the third through groove 312. Grains of different sizes enter the hulling assembly 6 through the guide trough 4;

[0056] S3: Grains of different sizes enter different chambers separated by the blocking plate 604 in the hulling cylinder 602. Then, the output end of the driving motor 610 drives the driving pulley 611 to rotate. Through the belt and the driven pulley 607, the main shaft 603 rotates. When the main shaft 603 rotates, the connecting rod 605 drives the extrusion plate 606 to rotate. The grains are hulled by the extrusion between the extrusion plate 606 and the hulling cylinder 602;

[0057] S4: After hulling, the grains enter the air separation cylinder 612 through the holes at the bottom of the hulling cylinder 602. At this time, the centrifugal fan 613 operates to blow air into the air separation cylinder 612. Since the weight of the grain husk is less than that of the grain endosperm, under the action of the air flow, the grain husk will be discharged through the husk discharge port 615, while the heavier endosperm will leak out from the discharge port 614 through the inclined bottom surface of the air separation cylinder 612 under the action of gravity.

9. A method for using a centrifugal shelling device, used to implement the centrifugal shelling device as claimed in claims 1 to 8, characterized in that: The following steps are involved: S1: First, the lifting motor (205), the servo motor (304), the drive motor (610) and the centrifugal fan (613) are powered on, and then the grains are poured into the storage barrel (216). Then, the lifting motor (205) drives the first bevel gear (206) to rotate, and drives the second bevel gear (207) to rotate through the meshing relationship, thereby realizing the rotation of the threaded rod (204) and then the moving block (215) moves upward to lift the grains through the threaded matching relationship. After the storage barrel (216) reaches the highest point, the output end of the cylinder (211) extends to push the push block (210) to slide upward along the guide rail (209), and pushes the flip plate (212) to rotate around the rotating shaft (214) through the connecting rod (213), so that the storage barrel (216) is tilted, and the grains in the storage barrel (216) are poured into the discharge hopper (302); S2: The discharge hopper (302) guides the grains into the sorting drum (307), and then the output end of the servo motor (304) drives the driving gear (305) to rotate. The driving gear (305) enables the sorting drum (307) to rotate between the rotating guide wheels (306) through the meshing relationship with the driving gear ring (308). When the sorting drum (307) rotates, the grains are transported from the right side to the left side through the internal spiral feeding sheet (309). During the transportation process, the grain particles of different sizes are screened into the guide groove (4) through the first through groove (310), the second through groove (311) and the third through groove (312). The grain particles of different sizes enter the shelling assembly (6) through the guide groove (4); S3: Grain particles of different sizes enter different chambers separated by the blocking plate (604) in the shelling cylinder (602), and then the output end of the driving motor (610) drives the driving pulley (611) to rotate, and the main shaft (603) rotates through the belt and the driven pulley (607). When the main shaft (603) rotates, the squeezing plate (606) is driven to rotate through the connecting rod (605), and the grains are shelled by squeezing the squeezing plate (606) and the shelling cylinder (602); S4: After shelling, the grains enter the air separation cylinder (612) through the hole at the bottom of the shelling cylinder (602). At this time, the centrifugal fan (613) works to blow gas into the air separation cylinder (612). Since the weight of the grain husk is less than the grain endosperm, under the action of the air flow, the grain husk will be discharged through the hull discharge port (615), while the heavier endosperm will leak out from the discharge port (614) through the inclined bottom surface of the air separation cylinder (612) under the action of gravity.
