Description

A lotus seed sorting device with automatic feeding capability Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a lotus seed screening device with automatic feeding capability. Background Technology

[0002] Lotus seeds are both a medicinal herb and a food ingredient. Their quality grade is mainly determined by the size of a single lotus seed. Therefore, during the processing of lotus seeds, they often need to be sieved according to their size.

[0003] Patent CN221674875U discloses an automatic feeding lotus seed screening device, which includes a support plate; a screening box mounted on the support plate; multiple screens, all of which are placed inside the screening box; a hopper, which is fixedly installed on the top of the support plate; and a feeding mechanism mounted on the support plate and connected to the hopper. The automatic feeding lotus seed screening device provided by this patent can automatically feed lotus seeds, which is convenient and simple to operate, eliminating the need for manual feeding by staff, thus improving work efficiency and providing convenience for workers.

[0004] However, in this patent, lotus seeds are sieved using a sieve, but the aperture of the sieve is fixed, so the sieving standard cannot be dynamically adjusted. Therefore, a new type of sieving device is needed to solve this problem. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a lotus seed screening device with automatic feeding capability, which can screen lotus seeds into multiple portions according to their size, and the screening standard can be adjusted during the screening process to dynamically adjust the size of each portion of lotus seeds screened out.

[0006] The technical solution to achieve the purpose of this utility model is as follows: an automatic feeding lotus seed screening device, including a shell, a feeding mechanism on one side of the shell, and a screening component inside the shell. The screening component includes partitions, through holes, round rods, rotating cylinders, discharge holes, a motor, rotating rods, gears, and transmission gears. Multiple partitions are fixedly connected to the inner wall of the shell. The partitions are hollow. Each partition has through holes at its top and bottom. Multiple round rods are provided on the inner wall of each partition. Multiple rotating cylinders are rotatably connected to multiple partitions. Multiple discharge holes are respectively opened on multiple rotating cylinders. The motor is fixedly connected to the shell. The rotating rod is fixedly connected to the output shaft of the motor. Multiple gears are fixedly connected to the rotating rods. Multiple sets of transmission gears are fixedly connected to multiple rotating cylinders. Each gear meshes with each set of transmission gears. An adjustment component is provided between the shell and the partitions.

[0007] Preferably, each of the partitions has a round rod fixedly connected inside, and the other round rods are slidably connected to the inner wall of the partition.

[0008] Preferably, the adjusting assembly includes a connecting block and a spring. Each of the round rods is fixedly connected to the connecting block, and the connecting blocks are slidably connected to the inner wall of each partition. The spring is fixedly connected between every two adjacent connecting blocks.

[0009] Preferably, the adjustment assembly further includes a slide rod and a slider, with a slide rod slidably connected to the inner wall of each partition, and multiple sliders slidably connected to each slide rod, with a slider disposed between every two adjacent connecting blocks.

[0010] Preferably, the adjustment assembly further includes screws and knobs, with multiple screws rotatably connected to the side wall of the housing, and multiple screws threadedly connected to multiple slide rods respectively. Multiple knobs are rotatably connected to the side wall of the housing, and multiple knobs are fixedly connected to multiple screws respectively.

[0011] Preferably, the adjustment assembly further includes fixing rods, with two fixing rods fixedly connected to the inner wall of each partition, and the round rod inside each partition being slidably connected to the fixing rods.

[0012] Compared with the prior art, the significant advantages of this utility model are:

[0013] Firstly, in this utility model, lotus seeds are continuously conveyed by a feeding mechanism, causing them to fall into the uppermost rotating drum. The lotus seeds fall through the dropping hole to the through hole and are screened by parallel round rods. Multiple round rods are evenly spaced, so lotus seeds with a diameter larger than the distance between the round rods cannot pass through, thus completing the screening. The lotus seeds that pass through the round rods will fall into the next rotating drum, and then repeat the process of passing through each set of round rods to complete multiple screenings. Finally, the lotus seeds are screened into multiple portions, each with a different size. After screening, multiple baffles on one side of the outer shell can be opened to remove the remaining lotus seeds in each rotating drum.

[0014] Secondly, in this invention, during the screening process, the motor can be started to rotate the rotating rod, which in turn rotates the gear and drives the rotating drum. When the drum rotates, the material discharge hole on it will also rotate. The shape and area of ​​the bottom of the material discharge hole are different from those of the through hole, so the lotus seeds in the material discharge hole will shake due to the rotation, ensuring that the lotus seeds fully contact the round rod and shake, thus ensuring that the lotus seeds that can pass through the round rod pass through. To adjust the screening standard, the knobs can be turned to rotate the screws. The rotation of the screws will drive the sliding rod to move, and the slider on it will move accordingly. Since each round rod is equipped with a connecting block, and springs are installed between the connecting blocks, the spacing between each round rod is the same and is limited by the springs. The movement of the slider will drive the spacing between the round rods, increasing or decreasing the spacing between each pair of adjacent round rods, while maintaining the round rods at equal intervals. Therefore, the screening standard of lotus seeds screened by each partition can be adjusted. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved lotus seed screening device with automatic feeding capability. The technical solution of this utility model is as follows:

[0025] As shown in Figures 1-5, an automatic feeding lotus seed screening device includes a shell 1. A feeding mechanism 2 is provided on one side of the shell 1. The feeding mechanism 2 is composed of a spiral roller and a drive motor, as used in the comparative patent. A screening assembly 3 is provided inside the shell 1. The screening assembly 3 includes partitions 31, through holes 32, round rods 33, a rotating drum 34, a discharge hole 35, a motor 36, a rotating rod 37, gears 38, and transmission gears 39. Multiple partitions 31 are fixedly connected to the inner wall of the shell 1. The partitions 31 have a hollow structure, and the top of each partition 31 and... Each part 31 has a through hole 32 at the bottom. Each partition 31 has multiple round rods 33 on its inner wall. Multiple rotating drums 34 are rotatably connected to the partitions 31. Multiple material discharge holes 35 are opened on the rotating drums 34. A motor 36 is fixedly connected to the outer shell 1. A rotating rod 37 is fixedly connected to the output shaft of the motor 36. Multiple gears 38 are fixedly connected to the rotating rod 37. Multiple sets of transmission gears 39 are fixedly connected to the rotating drums 34. Each gear 38 meshes with each set of transmission gears 39. An adjustment assembly 4 is provided between the outer shell 1 and the partitions 31.

[0026] Furthermore, each partition 31 has a fixedly connected round rod 33 inside, and the remaining round rods 33 are slidably connected to the inner wall of the partition 31. One round rod 33 in the center of the through hole 32 is fixed, while the round rods 33 on both sides are movable.

[0027] Furthermore, the adjusting component 4 includes a connecting block 41 and a spring 42. Each round rod 33 is fixedly connected to a connecting block 41, and the connecting blocks 41 are slidably connected to the inner wall of each partition 31. A spring 42 is fixedly connected between every two adjacent connecting blocks 41. Under the action of the spring 42, the spacing between each round rod 33 can remain the same, and the round rods 33 remain parallel. Therefore, the gap between the round rods 33 can be used to sieve lotus seeds. Since lotus seeds are close to spheres, this method can be used for sieving.

[0028] Furthermore, the adjustment assembly 4 also includes a slide rod 43 and a slider 44. A slide rod 43 is slidably connected to the inner wall of each partition 31, and multiple sliders 44 are slidably connected to each slide rod 43. A slider 44 is provided between every two adjacent connecting blocks 41. When the slide rod 43 moves, it drives the slider 44 to move. The slider 44 interacts between the connecting blocks 41. In conjunction with each spring 42, the distance between the connecting blocks 41 can be controlled, that is, the distance between the round rods 33 can be adjusted. Both sides of the slider 44 are inclined surfaces. Therefore, when the slider 44 moves, its inclined surfaces contact the connecting blocks 41, and the connecting blocks 41 will move, thereby adjusting the distance between the round rods 33.

[0029] Furthermore, the adjustment assembly 4 also includes screws 45 and knobs 46. Multiple screws 45 are rotatably connected to the side wall of the housing 1, and multiple screws 45 are threadedly connected to multiple slide rods 43 respectively. Multiple knobs 46 are rotatably connected to the side wall of the housing 1, and multiple knobs 46 are fixedly connected to multiple screws 45 respectively.

[0030] Furthermore, the adjustment assembly 4 also includes a fixing rod 47. Two fixing rods 47 are fixedly connected to the inner wall of each partition 31. The round rod 33 inside each partition 31 is slidably connected to the fixing rod 47. The fixing rod 47 passes through each round rod 33, keeping the round rod 33 parallel.

[0031] The specific working method is as follows: lotus seeds are continuously conveyed by the feeding mechanism 2, causing them to fall into the uppermost rotating drum 34. The lotus seeds fall through the dropping hole 35 into the through hole 32 and are screened by parallel round rods 33. Multiple round rods 33 are set at equal intervals, so lotus seeds with a diameter larger than the distance between the round rods 33 cannot pass through, thus completing the screening. The lotus seeds that pass through the round rods 33 will fall into the next rotating drum 34, and then repeat the process of passing through each set of round rods 33, completing multiple screenings. Finally, the lotus seeds are screened into multiple portions, and the size of each portion of lotus seeds is different. After screening is completed, multiple baffles on one side of the outer shell 1 can be opened to remove the remaining lotus seeds in each rotating drum 34.

[0032] During the screening process, the motor 36 can be started to rotate the rotating rod 37, which in turn rotates the gear 38, and through the transmission gear 39, the rotating drum 34 rotates. When the rotating drum 34 rotates, the material discharge hole 35 on it will also rotate. The shape and area of ​​the bottom of the material discharge hole 35 are different from those of the through hole 32. Therefore, the lotus seeds in the material discharge hole 35 will shake due to the rotation, ensuring that the lotus seeds fully contact and shake with the round rod 33, ensuring that the lotus seeds that can pass through the round rod 33 pass through. To adjust the screening standard, the various knobs 46 can be rotated. This causes each screw 45 to rotate, which in turn drives the slide bar 43 to move, and the slider 44 on it to move accordingly. Since each round rod 33 is equipped with a connecting block 41, and springs 42 are installed between the connecting blocks 41, the spacing between each round rod 33 is the same and is restricted by the springs 42. The movement of the slider 44 will drive the spacing between the round rods 33, making the spacing between each pair of adjacent round rods 33 increase or decrease, and keeping the round rods 33 evenly distributed. Therefore, the sieving standard of each partition 31 for sieving lotus seeds can be adjusted.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
