Description

Technical Field

[0001] This invention relates to the field of lotus seed production and conveying technology, specifically to a lotus seed processing and core removal device. Background Technology

[0002] Lotus seeds are harvested in autumn after the fruit matures. After harvesting, the lotus seeds are peeled, cored, and washed. They can be used as raw materials for various foods. Both the lotus seed meat and the lotus seed core are edible. Generally, to prevent the food from becoming bitter, the lotus seed core is removed before processing. The lotus seed core can be used as a traditional Chinese medicine.

[0003] Before removing the core from lotus seeds, they need to be screened to select lotus seeds of different sizes. After peeling, a core-removing machine or core-removing machine is used to completely remove the core from the lotus seeds. Then, the lotus seeds and lotus seed cores are collected separately. The most important part of the lotus seed core removal process is the positioning process. If the positioning is off, the lotus seed itself will be damaged during core removal, and the lotus seed core will not be completely removed. Some lotus seed core will remain inside the lotus seed, resulting in defective products.

[0004] In existing lotus seed removal machines, the positioning of lotus seeds can be broadly categorized into the following types: One type uses mechanical positioning, utilizing the characteristic that the lotus seed has a core at the tail end and its center of gravity is closer to the tail end, allowing the lotus seeds to naturally distribute with the tail end facing downwards. This method has high accuracy, but some lotus seeds still cannot be positioned correctly. Another type uses a visual method, which detects the difference in color between the head and tail of the lotus seed and uses a rotating mechanism to rotate the lotus seed after detecting the color of the tail end, ensuring that the tail ends face the same direction. A third type uses a through-hole screening method. The through-hole is conical, and the lotus seed head has no core protrusion, is round and plump, with a diameter slightly larger than the tail. The tail has a core root protrusion, is relatively pointed, and the core root is concentrated at the tail. It is said that due to the limitation of the core removal path, that is, the core removal path in the left and right direction, only one lotus seed can be cored at a time. Existing core-removing machines increase the number of core-removing needles. Generally speaking, small core-removing machines priced under 20,000 yuan have two core-removing needles working simultaneously, and can produce about 60-80 jin of lotus seeds per hour. Those priced under 50,000 yuan have eight core-removing needles working on four tracks. The common feature of the above positioning methods is that the lotus seeds are placed horizontally during transportation, and the core removal is done in a horizontal movement. This way of transporting lotus seeds undoubtedly limits the core-removing speed, and can only be improved in the direction of core-removing speed and positioning speed. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a lotus seed processing and core removal device that effectively solves the problem of how to change the original core-removing direction of lotus seeds during transport.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a lotus seed processing and core removal device, comprising a transmission belt frame and a drive roller, wherein a chain is drivenly connected to the drive roller, and further comprising: The lotus seed conveyor belt is installed between two chains on the left and right sides. It includes multiple conveyor bars and conical semi-steel rings embedded in the conveyor bars. The multiple conveyor bars together form a conveyor belt for transporting lotus seeds. The top diameter of the conical semi-steel ring is larger than the bottom diameter, and the top diameter is larger than the diameter of the tail of the lotus seed but smaller than the diameter of the head of the lotus seed. The core removal assembly is installed between the transmission belt frames and between the two layers of the conveyor belt composed of lotus seed conveyor belts. It includes a core removal needle that moves vertically and a box for collecting lotus seed cores. The core removal needle is connected to an external air source and can remove the cores from the lotus seeds inside the conical semi-steel ring by moving upwards.

[0007] Furthermore, a vertical positioning assembly is installed above the transmission belt frame, including a feeding hopper fixedly installed on the top of the transmission belt frame by a support column. Multiple dividing strips are fixedly connected inside the feeding hopper, and the spacing between the dividing strips is only for lotus seeds to fall vertically. Below the feeding hopper, corresponding to the intervals of the dividing strips, there are V-shaped push plates and rotating blocks. The V-shaped push plates are close to the rotating blocks to straighten the position of the lotus seeds falling from the intervals of the dividing strips.

[0008] Furthermore, the vertical positioning assembly also includes a fixing plate and a bracket fixedly installed on the top of the transmission belt frame by a support column. Multiple cylinders are fixedly connected to the bracket. A motor is fixedly connected to the output shaft of the cylinder. An elastic telescopic rod is fixedly connected to the drive shaft of the motor. The V-shaped push plate is fixedly connected to the elastic telescopic rod.

[0009] Furthermore, multiple micro switches are fixedly connected to the fixed plate, and the multiple micro switches are mounted together on the PCB board. The rotating block corresponds to each micro switch. The rotating block is rotatably mounted on the fixed plate, and there is a gap between the fixed plate and the lotus seed conveyor belt for the lotus seed head to move.

[0010] Furthermore, the core removal assembly also includes a base plate that is slidably inserted into the bottom of the box body, and the base plate is installed at the bottom of the box body by bolts; The bottom plate has multiple through holes corresponding to the core-removing needle. When the core-removing needle removes the core, the lotus seed core passes through the through holes in the bottom plate and enters the box.

[0011] Furthermore, several uniformly arranged rubber flaps are fixedly connected inside the through holes of the base plate, and an electric push rod is fixedly connected between the outer edge of the box and the transmission belt frame. When the core-removing needle rises to pass through the core, the electric push rod drives the box and the bottom plate to move downwards, and the lotus seed head extends into the rubber valve and is held in place by the rubber valve.

[0012] Furthermore, a movable plate is slidably installed on the back plate of the feeding hopper, and a friction plate inside the feeding hopper is fixedly connected to the upper part of the movable plate, the friction plate being in contact with the lotus seeds; A cylinder is fixedly connected between the moving plate and the side plate of the feeding hopper. The cylinder drives the moving plate to move back and forth left and right, and the friction plate rubs the lotus seeds, making them tend to be vertical.

[0013] Furthermore, two electric push rods are symmetrically fixedly connected to the top of the transmission belt frame, and a connecting plate is fixedly connected to the top of the two electric push rods. The core-removing needle is fixedly installed on the top of the connecting plate.

[0014] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By using a lotus seed conveyor belt in conjunction with a core removal component, an upward core removal action can be achieved, increasing the number of cores removed simultaneously and improving the core removal speed. Furthermore, the rubber flaps in the core removal component hold the head of the lotus seed in place during the core removal process, preventing the lotus seed from being pushed upwards too much and ensuring normal core removal. The closable rubber flaps also allow for the neat collection of lotus seed cores.

[0015] 2. By using a vertical positioning component, the horizontal kneading helps to position the lotus seeds vertically, and the V-shaped push plate pushes the lotus seeds to the correct position. When the lotus seeds are turned upside down, the rotation can also be used to drive the lotus seeds to flip over, helping to adjust the position of the lotus seeds and ensuring that the lotus seed axis is parallel to the core removal needle axis when removing the core later.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Reference Figures 1 to 9 Example: A lotus seed processing and core removal device includes a transmission belt frame 1 and a drive roller 2, with a chain 3 drivingly connected to the drive roller 2, and further includes: The lotus seed conveyor belt 4 is installed between the left and right chains 3. It includes multiple conveyor bars 401 and a conical semi-steel ring 402 embedded in the conveyor bars 401. The multiple conveyor bars 401 together form a conveyor belt for transporting lotus seeds. The top diameter of the conical semi-steel ring 402 is larger than the bottom diameter, and the top diameter is larger than the diameter of the tail of the lotus seed but smaller than the diameter of the head of the lotus seed. The core-removing assembly 6 is installed between the transmission belt frames 1 and between the two layers of the conveyor belt composed of the lotus seed conveyor belt 4. It includes a vertically moving core-removing needle 601 and a box 603 for collecting lotus seed cores. The core-removing needle 601 is connected to an external air source and can remove the cores from the lotus seeds inside the conical semi-steel ring 402. The core-removing assembly 6 also includes a base plate 604 that is slidably inserted into the bottom of the box 603. The base plate 604 is installed at the bottom of the box 603 by bolts. The base plate 604 has multiple through holes corresponding to the core-removing needle 601. When the core-removing needle 601 removes the cores, the lotus seed cores pass through the through holes of the base plate 604 and enter the box 603. Several evenly arranged rubber flaps 605 are fixedly connected in the through hole of the base plate 604. An electric push rod 607 is fixedly connected between the outer edge of the box body 603 and the transmission belt frame 1. When the core-removing needle 601 rises to remove the core, the electric push rod 607 drives the box body 603 and the base plate 604 to move down together. The lotus seed head extends into the rubber flaps 605 and is held in place by the rubber flaps 605. Two electric push rods 602 are symmetrically fixedly connected to the top of the transmission belt frame 1. A connecting plate 606 is fixedly connected to the top of the two electric push rods 602. The core-removing needle 601 is fixedly installed on the top of the connecting plate 606.

[0022] The lotus seed is generally drum-shaped or ellipsoidal, but the geometric features at both ends are significantly different: one end is the pointed end of the lotus seed core, which is conical with a taper of about 30°-60°, and the diameter gradually decreases from the root to the tip; the other end is the rounded end of the lotus seed pod, which is arc-shaped with a large curvature and no gradual change in the diameter at the end, and the overall diameter is larger than the diameter at the tail. When positioning, the tail of the lotus seed is mainly located, so that when removing the core, it can be removed directly from the starting point of the lotus seed core germination, along with the root, leaving no residue after core removal.

[0023] The axis of the lotus seed core coincides perfectly with the tapered axis of the lotus seed tip. As long as the tip is precisely aligned with the axis of the conical semi-steel ring 402, the lotus seed core axis can be initially aligned with the axis of the subsequent core-removing needle 601. When the lotus seed falls with its tail facing down, it can smoothly pass through the top of the conical semi-steel ring 402 and finally fall into the bottom of the conical semi-steel ring 402. However, when the lotus seed falls with its head facing down, it will be directly stuck above the conical semi-steel ring 402 and cannot fall completely into the conical semi-steel ring 402. This is used to screen and position the lotus seeds. The lotus seeds with their tails facing down can be cored by the upward-moving core-removing needle 601. The core-removing needle 601 has a small needle hole for connecting to an external air source. During core removal, air pressure can be used to quickly blow out the lotus seed core. Since this technology is a mature existing technology and has been widely used in existing core-removing machines, only the distribution of 610 is shown. The air source, control system and other related equipment are not further limited here.

[0024] The conical semi-conical steel ring 402, when the two conveyor bars 401 are parallel, forms a complete conical through hole with the conical semi-conical steel rings 402 on the two conveyor bars 401. This through hole is used to receive lotus seeds. Due to the change in the de-coring direction and the cooperation of the conveyor bars 401 and the conical semi-conical steel ring 402, vertically distributed lotus seeds can be received. Therefore, on the lotus seed conveyor belt 4, one or more rows of lotus seeds can be de-cored simultaneously, which undoubtedly improves the working efficiency of the existing de-coring machine. Under the same positioning speed conditions, only the number of feeding devices needs to be increased to quickly increase the de-coring speed of lotus seeds. (This is in contrast to the electric push rod 60...) Compared to horizontal core removal, horizontal core removal limits the vertical space to only one lotus seed. If multiple lotus seeds are to be cored at once in the horizontal core removal direction, the electric push rod 602 cannot pass through two or more lotus seeds at a time. Therefore, the equipment needs to add a conveyor belt for transporting lotus seeds and a matching electric push rod 602, which will occupy more horizontal space and require more matching lotus seed positioning equipment. The advantage of vertical core removal is that it increases the number of lotus seeds that can be cored in the horizontal space, providing more favorable room for improvement in the subsequent improvement of the core removal speed.

[0025] Specifically, a vertical positioning component 5 is installed above the transmission belt frame 1, including a feeding hopper 501 fixedly installed on the top of the transmission belt frame 1 by a support column. Multiple dividing strips 504 are fixedly connected inside the feeding hopper 501. The spacing of the dividing strips 504 is only for lotus seeds to fall vertically. Below the feeding hopper 501, corresponding to the intervals of the separator strip 504, there are V-shaped push plates 510 and rotating blocks 512. The V-shaped push plates 510 are close to the rotating blocks 512 to straighten the position of the lotus seeds falling from the separator strip 504.

[0026] Furthermore, a movable plate 502 is slidably installed on the back plate of the feeding hopper 501. A friction plate 503 located inside the feeding hopper 501 is fixedly connected to the upper part of the movable plate 502. The friction plate 503 contacts the lotus seeds. A cylinder 505 is fixedly connected between the movable plate 502 and the side plate of the feeding hopper 501. The cylinder 505 drives the movable plate 502 to move back and forth left and right, and the friction plate 503 rubs the lotus seeds, making them tend to be vertical.

[0027] Inside the feeding hopper 501, lotus seeds are agitated by the reciprocating friction plate 503, gradually causing the horizontally positioned lotus seeds to become vertical until they fall between the separator bars 504. The friction plate 503 can be made of a flexible material such as rubber, increasing contact with the lotus seeds without damaging them. It is important to note that the section of the feeding hopper 501 with the separator bars 504 should only allow one lotus seed to pass vertically at a time; a width that is too wide or too narrow will cause problems with the guidance of the lotus seeds. The spacing of the separator strips 504 corresponds to the position of the conical semi-steel ring 402. The separator strips 504 can be welded into the feeding hopper 501, or threaded holes can be made in the separator strips 504 and bolts can be used to fasten them into the feeding hopper 501. The spacing of the separator strips 504 needs to be adjusted according to the specifications of the lotus seeds. The position of the conical semi-steel ring 402 is fixed. The conical semi-steel ring 402 can be customized with different thicknesses, while the taper can be kept consistent. The conical semi-steel ring 402 can be fixed to the conveyor strip 401 by adhesive bonding, or threaded holes can be made on the side of the conical semi-steel ring 402 and bolts can be used to fasten it to the conveyor strip 401 laterally, or a magnetic attraction method can be used, in which a sufficiently strong magnet is installed in the conveyor strip 401 to attract the conical semi-steel ring 402 to the conveyor strip 401.

[0028] The lotus seeds are temporarily stored in the feeding hopper 501. During the falling process, the lotus seeds are restricted in their falling direction by the separator 504 and fall into the conical semi-steel ring 402. The falling process requires the cooperation of the reduction motor on the drive roller 2. The drive roller 2 stops briefly and then continues to run, and this cycle continues. After falling, the lotus seeds will be distributed with their heads down or tails down. The lotus seeds with their heads down will stay above the conical semi-steel ring 402.

[0029] Specifically, the vertical positioning component 5 also includes a fixing plate 511 and a bracket 506 fixedly installed on the top of the transmission belt frame 1 by a support column. Multiple cylinders 507 are fixedly connected to the bracket 506. A motor 508 is fixedly connected to the output shaft of the cylinders 507. An elastic telescopic rod 509 is fixedly connected to the drive shaft of the motor 508. A V-shaped push plate 510 is fixedly connected to the elastic telescopic rod 509.

[0030] Multiple micro switches 513 are fixedly connected to the fixed plate 511. The multiple micro switches 513 are mounted together on the PCB board, and the rotating block 512 corresponds to each of the micro switches 513. The rotating block 512 is rotatably mounted on the fixed plate 511. There is a gap between the fixed plate 511 and the lotus seed conveyor belt 4 for the lotus seed head to move.

[0031] When drive roller 2 stops rotating, cylinder 2 507 operates synchronously, and drive motor 508 and related components of V-shaped push plate 510 extend outward. V-shaped push plate 510 contacts the lotus seeds falling from below feeding hopper 501. If the lotus seeds fall with their tails down, V-shaped push plate 510 only contacts the head of the lotus seed. The V-shaped push plate 510, moving towards the lotus seed, pushes the head of the lotus seed towards rotating block 512, calibrating the position of the lotus seed and keeping its axis vertical. However, if the lotus seed moves with its head down, V-shaped push plate 510 pushes the lotus seed, causing the tail of the lotus seed to contact the area above rotating block 512. When the micro switch 513 is activated, the motor 508 behind the V-shaped push plate 510 will drive the elastic telescopic rod 509 and the V-shaped push plate 510 to rotate 180° together. At this time, the V-shaped push plate 510 can cooperate with the rotating block 512 to hold the lotus seed and flip it 180° so that the tail of the lotus seed is facing down. Then the lotus seed falls into the conical hole semi-steel ring 402. Then the drive roller 2 rotates. Since the lotus seed has fallen into the conical hole semi-steel ring 402, the part of the lotus seed's head that exceeds the top surface of the conveyor bar 401 is small. A certain gap needs to be left between the fixed plate 511 and the conveyor bar 401 so that the lotus seed can move through.

[0032] The movement of the V-shaped pusher plate 510 toward the lotus seeds helps to straighten their position and keep their axis vertical. If the lotus seeds are in the wrong position, the V-shaped pusher plate 510 can rotate to adjust their orientation so that the tails are facing down, allowing all the lotus seeds in a row to be cored. This allows for quick positioning of the lotus seeds. Unlike vision-based solutions, the micro switch 513's control system is simpler, lower in cost, and occupies less space, making it more suitable for vertically arranged lotus seeds.

[0033] When the drive roller 2 pauses rotation, multiple core-removing needles 601 rise synchronously under the drive of the electric push rod 602, inserting themselves into the lotus seed from the tail end upwards. With the action of an external air source, the lotus seed core is blown upwards. As the core-removing needles 601 rise, the base plate 604 and the box body 603 move downwards synchronously. The rubber flaps 605 on the base plate 604 press against the head of the lotus seed. The rubber flaps 605, through their elasticity, press down on the head of the lotus seed, restricting its further rise. As the core-removing needles 601 rise, they exert an upward force on the lotus seed. At this time, the rubber flaps 605 restrict the lotus seed from rising further. Under the applied force, a hole is squeezed out in the middle of the multiple rubber valves 605. The lotus seed core can pass through the rubber valve 605 under air pressure and enter the sealed space formed by the box 603 and the bottom plate 604. After the core removal is completed, the electric push rod 607 drives the box 603 and the bottom plate 604 to rise. The rubber valve 605 returns to its original shape and seals the through hole at the bottom of the bottom plate 604. The lotus seed core cannot fall out of the bottom plate 604. In this way, when removing the core, the lotus seed core and various fragments sprayed out from the lotus seed will only exist in the box 603 and the bottom plate 604, which can maintain the cleanliness of the equipment to a certain extent.

[0034] It should be noted that since the exposed portion of the lotus seed inside the conical semi-steel ring 402 is small, the contact area between the rubber valve 605 and the lotus seed is also small. After the core-removing needle 601 rises, the lotus seed will not cause the rubber valve 605 to deform at a near 90° angle. Therefore, the lotus seed cannot get stuck inside the rubber valve 605. After the box body 603 rises, the rubber valve 605 will squeeze the head of the lotus seed under its own elasticity and squeeze the lotus seed out. Since only the lotus seed needs to be collected later, it is not important that the position of the lotus seed changes after it falls.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
