Description

Technical Field

[0001] The utility model relates to the technical field of lotus seed processing, in particular to a core removing device for lotus seed production. Background Art

[0002] Lotus seeds, a traditional Chinese medicine, are the dried mature seeds of the lotus plant of the Nymphaeaceae family. Lotus seeds are a food that can be eaten directly. Because the lotus core inside tastes bitter, the lotus seeds can only be eaten after being peeled and cored.

[0003] At present, in order to improve processing efficiency, lotus seeds are generally directly put into a core removing machine to complete the automatic core removal operation during processing. However, during use, the existing core removing machine is difficult to keep the lotus seeds in a vertical state with the long diameter up and down. As a result, some lotus seeds are in a horizontal state, and the core removing mechanism directly passes through the lotus seeds. Not only can the lotus core not be pushed out, but the lotus seeds themselves are also damaged, resulting in a large amount of lotus seeds being wasted. There is still room for improvement. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1, with reference to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A lotus seed coring device comprises a processing table 1, a collecting frame 2 is plugged into the front of the processing table 1, a conveying assembly is fixedly connected to the upper surface of the processing table 1, a positioning table 3 is fixedly connected to the upper surface of the processing table 1, a positioning plate 4 is fixedly connected to the front of the positioning table 3, a coring assembly is fixedly connected to the upper surface of the positioning plate 4, and the conveying assembly comprises a U-shaped frame 5, the inner wall of the U-shaped frame 5 is rotatably connected to a conveying chain plate 6, a coring groove is opened on the upper surface of the conveying chain plate 6, and a coring through hole is opened on the inner bottom wall of the coring groove;

[0023] Two cavities are provided inside the conveying chain plate 6, and the inner walls of the two cavities are slidably connected with movable plates 7, and the opposite surfaces of the two movable plates 7 are fixedly connected with push rods 8, and the opposite ends of the two push rods 8 extend to the inside of the core removing groove, and the inner wall of the core removing groove is provided with two circular holes adapted to the push rods 8, and the opposite ends of the two push rods 8 are fixedly connected with arc-shaped clamping frames 9, and the inner walls of the two cavities are fixedly connected with two positioning rods 10, and the movable plate 7 is slidably connected to the surfaces of the two positioning rods 10, and the surfaces of the two positioning rods 10 are sleeved with first springs 11, one end of the first spring 11 overlaps the movable plate 7, and the other end overlaps the inner wall of the cavity;

[0024] The two arc-shaped clamping brackets 9 can, through the acting force of the first spring 11 itself, use the movable plate 7 and the ejector rod 8 to clamp the lotus seeds tightly in the core-removing groove, ensuring that the lotus seeds can be core-removed in a vertical state, so as to ensure that the lotus cores inside the lotus seeds can be ejected, improving the core-removing effect on the lotus seeds;

[0025] The core-removing component includes a hydraulic push rod 12. The output end of the hydraulic push rod 12 is fixedly connected with a core-removing ejector pin 13. The surface of the core-removing ejector pin 13 is fixedly connected with a locking plate 14. The lower surface of the locking plate 14 is fixedly connected with two sleeves 15. The inner top walls of the two sleeves 15 are fixedly connected with second springs 16. The inner walls of the two sleeves 15 are slidably connected with sliding plates 17. The bottom ends of the second springs 16 are fixedly connected with the upper surfaces of the sliding plates 17. The lower surfaces of the two sliding plates 17 are fixedly connected with support rods 18. And the bottom ends of the sleeves 15 are provided with fixing holes adapted to the support rods 18. The bottom ends of the two support rods 18 are fixedly connected with a pre-pressing plate 19. The upper surface of the pre-pressing plate 19 is provided with a circular hole. The inner wall of the circular hole is fixedly connected with a pre-pressing cylinder 20. The upper surface of the pre-pressing cylinder 20 is provided with a core-removing circular through-hole. The position of the core-removing ejector pin 13 corresponds to the position of the core-removing circular through-hole;

[0026] During the descending process of the core-removing ejector pin 13, it can first drive the pre-pressing plate 19 to descend through the locking plate 14, the sleeves 15 and the support rods 18. The pre-pressing plate 19 can drive the pre-pressing cylinder 20 to first contact the surface of the lotus seed. The pre-pressing cylinder 20 can press the lotus seed tightly to ensure the stability of the lotus seed during the core-removing process, so that the lotus seed will not shift or shake. At the same time, the support rod 18 drives the sliding plate 17 upward to squeeze the second spring 16. The core-removing ejector pin 13 can pass through the core-removing circular through-hole and insert into the lotus seed to eject the lotus core in the lotus seed, eliminating the need for manual operation by workers and improving the processing efficiency of the lotus seeds.

[0027] Example 2: Refer to Figure 1 and Figure 4 , a discharge hole is provided on the back surface of the U-shaped frame 5. A blanking through-hole is provided on the upper surface of the processing table 1. A strip-shaped groove is provided on the front surface of the positioning table 3. An air suction fan 21 is fixedly connected to the inner wall of the strip-shaped groove. The position of the air suction fan 21 corresponds to the position of the discharge hole;

[0028] The core-removed lotus cores fall on the lower conveyor chain plate 6 through the core-removing through-hole. Since a discharge hole is provided on the back surface of the U-shaped frame 5, the suction force generated by the air suction fan 21 can suck the lotus cores out of the discharge hole and make the lotus cores fall into the collection box 2 through the blanking through-hole to complete the automatic collection operation.

[0029] Working principle: First, the staff places the lotus seeds in each core removal groove, and uses two arc-shaped clamping frames 9 to hold the lotus seeds on the surface so that the lotus seeds can stand vertically in the core removal groove. When the conveying chain plate 6 drives the lotus seeds to move to the position of the core removal pin 13, the hydraulic push rod 12 is activated, and the hydraulic push rod 12 can drive the core removal pin 13 to descend. The core removal pin 13 first drives the pre-pressing plate 19 to descend through the locking plate 14, sleeve 15 and support rod 18. The pre-pressing plate 19 drives the pre-pressing cylinder 20 to first contact the surface of the lotus seeds. The pre-pressing cylinder 20 can press the lotus seeds tightly in the core removal groove, thereby To ensure the stability of the lotus seeds during the coring process, when the pre-compression cylinder 20 contacts the lotus seeds, the pre-compression plate 19 can drive the support rod 18 to move upward, thereby squeezing the second spring 16 through the slide plate 17. At the same time, the coring ejector pin 13 passes through the coring circular through hole and enters the lotus seeds from just above the lotus seeds to eject the lotus cores in the lotus seeds. The lotus cores fall onto the conveying chain plate 6 on the lower layer through the coring through hole and are attracted by the suction effect of the suction fan 21 at the same time. They enter the collecting frame 2 through the discharge hole and the blanking through hole, completing the collection operation of the lotus seeds and lotus cores and improving the coring efficiency of the lotus seeds.
