[0001] The utility model relates to the technical field of lotus seed processing, in particular to a screw lotus seed processing and classifying machine. Background Art

[0002] Lotus seeds, a Chinese medicine name, are the dried mature seeds of the Nymphaeaceae plant, which are distributed in provinces in the north and south of my country. They have the effects of tonifying the spleen and stopping diarrhea, stopping leukorrhea, benefiting the kidneys and astringing sperm, nourishing the heart and calming the mind. They are often used for spleen deficiency diarrhea, leukorrhea, spermatorrhea, palpitations and insomnia.

[0003] For example, a Chinese patent discloses: a lotus seed processing quality classification device, patent number: CN215507647U, which separates lotus seeds into two adjacent classification barrels through a distributor, and discharges them to the outside through a collecting hopper and a distributor pipe, thereby achieving the purpose of sorting lotus seeds according to their size.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: during the lotus seed grading and feeding, the above device passed the lotus seeds into the inside of the feeding pipe through the feeding hopper, lacking a quantitative feeding function, resulting in inconsistent amounts of conveying and sorting each time, and too many lotus seeds being put in at one time, resulting in accumulation, affecting the grading efficiency and quality. Utility Model Content

[0015] (III) Beneficial effects

[0016] 1. During the feeding process, lotus seeds are put into the feeding hopper, the motor is started, and the motor output shaft drives the ring to rotate through the conveying screw. During the rotation of the ring, the pushing block slides through the extrusion block. The pushing block slides and pushes the loaded lotus seeds from the rectangular groove to the conveying screw. When the pushing block loses the extrusion force, it is driven to reset by the action of the first spring, and the lotus seeds are fed and pushed through the intermittent rotation of the ring. The lotus seeds are transported forward through the rotation of the conveying screw, and the amount of each feeding is controlled to avoid accumulation caused by too much lotus seeds at one time. The pushing block slides through the intermittent rotation of the ring to push the feeding, so that the amount of lotus seeds put in is moderate, which is conducive to more uniform transportation of lotus seeds for grading, thereby improving the efficiency of grading and screening.

[0017] 2. After the lotus seeds are graded and screened, they fall into the discharging hopper. After the grading is completed, the lotus seeds fall along the inclined chute. When discharging, the lotus seeds are temporarily blocked in the inclined chute by the baffle. The rotating block is pressed, and the rotating block rotates to release the clamping limit of the baffle. After the baffle cancels the limit, it is lifted upward by the force of two second springs. At this time, the lotus seeds accumulated in the inclined chute slide down to control the amount of each discharging, avoid excessive or insufficient discharging, ensure the accurate delivery of materials in the production process, quickly and accurately complete the discharging operation, save discharging time, and improve production efficiency.

[0024] The embodiment of the present application provides a screw lotus seed processing and grading machine, which effectively solves the problem that the lotus seeds are put into the inside of the discharge pipe through the discharge hopper during the lotus seed grading and feeding, and lacks the quantitative feeding function, resulting in inconsistent amounts of conveying and sorting each time, and excessive lotus seeds are put in at one time, resulting in accumulation, which affects the grading efficiency and quality. During the feeding process, the lotus seeds are put into the feeding hopper, and the motor is started. The motor output shaft drives the circular ring to rotate through the conveying screw. During the rotation of the circular ring, the pushing block is squeezed by the extrusion block to slide. The pushing block slides from the rectangular groove to push the loaded lotus seeds onto the conveying screw. When the pushing block loses the squeezing force, it is driven to reset by the action of the first spring, and the lotus seed feeding and pushing are realized by the intermittent rotation of the circular ring. The lotus seeds are conveyed forward by the rotation of the conveying screw, and the amount of each feeding is controlled to avoid excessive lotus seeds being put in at one time and causing accumulation. The pushing block is pushed to slide by the intermittent rotation of the circular ring to push the feeding, so that the amount of lotus seeds put in is moderate, which is conducive to more uniform conveying and grading of the lotus seeds, thereby improving the efficiency of grading and screening. Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in the embodiment of the present application is to effectively solve the problem that in the lotus seed grading and feeding of the above-mentioned device, the lotus seeds are passed through the lower hopper into the interior of the lower feeding pipe, and the quantitative feeding function is lacking, resulting in inconsistent amounts of conveying and sorting each time, and excessive lotus seeds are put in at one time, resulting in accumulation, which affects the grading efficiency and quality. The overall idea is as follows: a screw lotus seed processing and grading machine comprises a grading box 11, a conveying screw 12 is rotatably connected inside the grading box 11, a ring 13 is sleeved on the outer surface of the conveying screw 12, two extrusion blocks 14 are fixedly connected to one side of the ring 13 close to the conveying screw 12, a push block 15 is slidably connected inside the grading box 11, and two first springs 16 are fixedly connected to the outer surface of the push block 15, and the two first springs 16 are fixedly connected to the inside of the grading box 11, and a feeding mechanism is fixedly connected inside the grading box 11, and the feeding mechanism comprises a feeding hopper 17, and the feeding hopper 17 is fixedly connected to the inside of the grading box 11, and a A rectangular groove 18 is provided, and a pusher block 15 is slidably connected inside the rectangular groove 18. A motor 19 is fixedly connected to one side of the grading box 11, and a conveying screw 12 is sleeved on the outer surface of the motor 19. During the feeding process, lotus seeds are put into the feeding hopper 17, and the motor 19 is started. The output shaft of the motor 19 drives the ring 13 to rotate through the conveying screw 12. During the rotation of the ring 13, the pusher block 15 is squeezed by the extrusion block 14 to slide. The pusher block 15 slides from the rectangular groove 18 to push the loaded lotus seeds onto the conveying screw 12. When the pusher block 15 loses the extrusion force, it is driven to reset by the force of the first spring 16, and the lotus seed feeding and pushing are realized by the intermittent rotation of the ring 13. The lotus seeds are conveyed forward by the rotation of the conveying screw 12, and the amount of each feeding is controlled to avoid accumulation caused by too much lotus seeds being put in at one time. The pusher block 15 is pushed to slide by the intermittent rotation of the ring 13 to push the feeding, so that the amount of lotus seeds put in is moderate, which is conducive to more uniform transportation and grading of the lotus seeds, thereby improving the efficiency of grading and screening.

[0026] A lower hopper 21 is fixedly connected to the lower end of the grading box 11. An inclined chute 22 is provided inside the lower hopper 21. Lotus seeds are put into the upper hopper 17. The lotus seeds are pushed by the pushing block 15 in the upper hopper 17 and slide to the outer surface of the conveying screw 12. The conveying screw 12 rotates to drive the lotus seeds to be conveyed forward and are graded into different sizes during the conveying process and fall into the lower hopper 21. After the grading is completed, the lotus seeds fall along the inclined chute 22 to achieve grading of the lotus seeds during the processing.

[0027] Two second springs 23 are fixedly connected inside the lower hopper 21, and baffles 24 are fixedly connected to the upper ends of the two second springs 23. The baffles 24 are slidably connected to the inside of the grading box 11. One end of the grading box 11 is rotatably connected to two rotating blocks 25. The two rotating blocks 25 are both clamped in the baffles 24. After the lotus seeds are graded and screened, they fall into the lower hopper 21. The lotus seeds after grading fall along the inclined chute 22. When the lotus seeds are discharged, the baffles 24 are temporarily blocked in the inclined chute 22. The rotating block 25 is pressed, and the rotating block 25 rotates to release the clamping limit of the baffle 24. After the baffle 24 cancels the limit, it is lifted upward by the force of the two second springs 23. At this time, the lotus seeds accumulated in the inclined chute 22 slide down to control the amount of each discharge, avoid excessive or insufficient discharge, ensure the accurate delivery of materials in the production process, quickly and accurately complete the discharge operation, save discharge time, and improve production efficiency.

[0028] In view of the problems existing in the prior art, the utility model provides a screw lotus seed processing and grading machine. During the feeding process, lotus seeds are put into a feeding hopper 17, and a motor 19 is started. The output shaft of the motor 19 drives a circular ring 13 to rotate through a conveying screw 12. During the rotation of the circular ring 13, a pushing block 15 is squeezed and slid by an extrusion block 14. The pushing block 15 slides from a rectangular groove 18 to push the loaded lotus seeds onto the conveying screw 12. When the pushing block 15 loses its squeezing force, it is driven to reset by the force of a first spring 16, and the lotus seed feeding and pushing are realized by the intermittent rotation of the circular ring 13. The lotus seeds are conveyed forward by the rotation of the conveying screw 12, and the amount of each feeding is controlled to avoid accumulation caused by too much lotus seeds being fed at one time. The pushing block 15 is pushed to slide by the intermittent rotation of the circular ring 13 to push the feeding, so that the amount of lotus seeds fed is moderate, which is conducive to more uniform transportation and grading of the lotus seeds, thereby improving the efficiency of grading and screening.

[0029] Working principle:

[0030] In the first step, lotus seeds are put into the upper hopper 17. The lotus seeds are pushed by the push block 15 in the upper hopper 17 and slide to the outer surface of the conveying screw 12. The conveying screw 12 rotates to drive the lotus seeds to be conveyed forward and are graded into different sizes during the conveying process and fall into the lower hopper 21. The lotus seeds after grading fall along the inclined chute 22 to achieve the grading of lotus seeds during the processing. During the feeding process, the lotus seeds are put into the upper hopper 17, and the motor 19 is started. The output shaft of the motor 19 drives the ring 13 to rotate through the conveying screw 12. During the rotation of the ring 13, the push block 14 squeezes and pushes the ring 13. The block 15 slides, and the pushing block 15 slides to push the loaded lotus seeds from the rectangular groove 18 onto the conveying screw 12. When the pushing block 15 loses the extrusion force, it is driven to reset by the force of the first spring 16, and the lotus seed loading and pushing are realized by the intermittent rotation of the ring 13. The lotus seeds are conveyed forward by the rotation of the conveying screw 12, and the amount of each feeding is controlled to avoid accumulation caused by too much lotus seeds being put in at one time. The pushing block 15 is pushed to slide by the intermittent rotation of the ring 13 to push the feeding, so that the amount of lotus seeds put in is moderate, which is conducive to more uniform transportation of the lotus seeds for grading, thereby improving the efficiency of grading and screening.

[0031] In the second step, after the lotus seeds are graded and screened, they fall into the discharge hopper 21. The lotus seeds after grading fall along the inclined chute 22. When discharging, the lotus seeds are temporarily blocked in the inclined chute 22 by the baffle 24, and the rotating block 25 is pressed. The rotating block 25 rotates to release the clamping limit of the baffle 24. After the baffle 24 cancels the limit, it is lifted upward by the force of the two second springs 23. At this time, the lotus seeds accumulated in the inclined chute 22 slide down to control the amount of each discharging, avoid excessive or insufficient discharging, ensure the accurate delivery of materials in the production process, quickly and accurately complete the discharging operation, save discharging time, and improve production efficiency.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
