The discharge port of the shelling device 5 is provided with a secondary feeding device 6, and a peeling device 7 is provided below the secondary feeding device 6. The peeling device 7 can peel the lotus seeds to ensure the thorough removal of the surface skin of the lotus seeds while maintaining the integrity and quality of the lotus seeds. The peeling device 7 can remove the outer skin of the lotus seeds by rotating the friction wheel or by high-pressure water flushing or a combination of the two. A discharge hopper 8 is provided below the peeling device 7, and the lotus seeds that have been shelled, shelled and peeled can be discharged from the equipment in an orderly manner through the discharge hopper 8, which is convenient for subsequent collection and processing.

[0035] During use, the lotus seeds to be processed first enter the conveyor 3 through the feed device 2, where they are then shelled by the shelling device 4. The shelled lotus seeds continue to move forward along the conveyor 3, undergo further cleaning by the shelling device 5, enter the secondary feed device 6, and finally enter the peeling device 7 for a second peeling process. After processing, the lotus seeds are discharged from the equipment through the discharge hopper 8. By integrating the shelling and peeling functions, continuous and automated processing of lotus seeds is achieved, improving production efficiency. Furthermore, the double shelling and peeling processes ensure that the surface of the processed lotus seeds is free of residue, thus meeting market demand for high-quality lotus seeds.

[0036] In some embodiments, the feeding device 2 includes a main bucket 21, and an auxiliary bucket 22 is provided below the main bucket 21 to guide and distribute lotus seeds. There can be two auxiliary buckets 22, which are symmetrically arranged and can be processed simultaneously on both sides of the frame 1, thereby improving the processing efficiency of the all-in-one machine; at the same time, processing on both sides can improve the symmetry of the all-in-one machine, thereby improving the stability of the all-in-one machine during operation; a splint bucket 23 is provided below the auxiliary bucket 22, and a differential cam 24 is provided on one side of the splint bucket 23. The splint bucket 23 and the differential cam 24 form an arc-shaped discharge channel, which can make the lotus seeds fall according to a predetermined trajectory, while slowing down the falling speed of the lotus seeds, so that the lotus seeds are more stable when they reach the discharge port. The discharge port of the discharge channel is provided with a transmission device 3, and a needle stop assembly 25 is also provided at the discharge port of the discharge channel. The needle stop assembly 25 can control the number of lotus seeds entering the transmission device 3. The needle stop assembly 25 can include two needle stops symmetrically arranged at both ends of the discharge port of the discharge channel. The needle stop can be a crank plus spring structure. This is the existing technology and will not be repeated here. The needle stop can make intermittent reciprocating motion. When the two needle stoppers approach each other, the lotus seeds are prevented from entering the transmission device 3. When the two needle stoppers move away from each other, the lotus seeds enter the transmission device 3 for subsequent processing.

[0037] In some embodiments, the transmission device 3 includes a drive motor 31, a first rotating wheel 32, a second rotating wheel 33, a conveyor belt 34 and a tensioning wheel 35. The drive motor 31 can provide power for the entire transmission device 3. The drive motor 31 is transmission-connected to the first rotating wheel 32 and the second rotating wheel 33, and can be connected by belts and other devices to achieve different transmission ratios between the drive motor 31 and the first rotating wheel 32, and between the drive motor 31 and the second rotating wheel 33. The first rotating wheel 32 and the second rotating wheel 33 are transmission-connected by a conveyor belt 34. A feeding device 2 is provided above the conveyor belt 34. The conveyor belt 34 can realize the transportation of lotus seeds at the discharge port of the feeding device 2. The first rotating wheel 32 and the second rotating wheel 33 are transmission-connected by the conveyor belt 34 and are both transmission-connected to the drive motor 31, so that the transmission device 3 is transmitted through the two first rotating wheels, which can enhance the transmission capacity of the transmission device 3 and avoid slipping during the transmission process.

[0038] In some embodiments, a tensioning wheel 35 is further provided on the frame 1, which is in transmission connection with the conveyor belt 34. The tensioning wheel 35 can be used to adjust the tension of the conveyor belt 34, so that the conveyor belt 34 always maintains the optimal tension state, ensuring stability and reliability during the transmission process.

[0039] In some embodiments, the shelling device 4 includes a cover plate 41, an elastic shell member 42, a driving mechanism 43 and a cutter 44. The cover plate 41 is arranged above the conveyor belt 34. The cover plate 41 is provided with an elastic shell member 42 on the side away from the feeding device 2. An extrusion shelling area is formed between the elastic shell member 42 and the conveyor belt 34. The elastic shell member 42 and the conveyor belt 34 can be used to squeeze the lotus seeds to easily achieve preliminary shelling of the lotus seeds. The elastic shell member 42 can be made of a material with a certain elasticity such as silicone, which can squeeze the lotus seeds while avoiding excessive squeezing force on the lotus seeds, thereby causing damage to the lotus seeds. , to avoid affecting the quality of the processed lotus seeds; a driving mechanism 43 is provided on the cover plate 41, and a cutter 44 is provided on the driving mechanism 43. A sliding groove 411 is provided on the cover plate 41, and the cutter 44 is plugged into the sliding groove 411 and can slide in the sliding groove 411. The driving mechanism 43 drives the cutter 44 to reciprocate in the sliding groove 411, thereby realizing the cutting process of the lotus seeds. The driving mechanism 43 can be an eccentric wheel structure connected to the driving motor 31. The eccentric wheel rotates, so that the driving mechanism 43 drives the cutter 44 to reciprocate. This is a prior art and will not be described in detail here.

[0040] In some embodiments, the shelling device 5 includes a shelling frame 51, on which two rotatable augers 52 are provided. The two augers 52 are arranged parallel to the discharge port of the transmission device 3, and the augers 52 are connected to the drive motor 31 for transmission. They can be connected through a gear structure to achieve different transmission ratios between the augers 52 and the drive motor 31, thereby achieving the optimal rotation speed of the augers 52 to ensure the shelling effect of the lotus seeds; the two augers 52 rotate in opposite directions, so that the two augers 52 move in a rolling mode, thereby enhancing the shelling effect of the augers 52 on the lotus seeds; a baffle 53 is provided on one side of the shelling frame 51 to prevent the lotus seeds from entering the shelling device 5 at too high a speed and falling from the shelling device 5. A secondary feeding device 6 is provided below the two augers 52 away from the baffle 53, which can send the lotus seeds that have been shelled and shelled to the next processing stage in an orderly manner. The secondary feeding device 6 can be provided with an intermittent wheel at the feeding port. The intermittent wheel is provided with grooves. The lotus seeds fall from the shelling device 5 into the grooves on the intermittent wheel and follow the rotation of the intermittent wheel to fall from the secondary feeding device 6 into the peeling device 7.

[0041] Specifically, when the lotus seeds processed by the shelling device 4 enter the shelling device 5, the lotus seeds fall on the two augers 52, and the augers 52 rotate, causing friction between the lotus seeds and the two augers 52. This friction drives the lotus seeds to move toward the secondary feeding device 6, while making the friction of the lotus flesh in the lotus seeds and the shell on the augers 52 different, so that the lotus flesh and the shell rotate relative to each other, thereby achieving separation of the lotus flesh from the remaining shell. Since the shell remaining on the lotus flesh is a semicircular shell with a hollow structure, the rotation of the two augers 52 will squeeze and deform the shell, so that the shell is compressed into a flat shape by force, and then falls from the gap between the two augers 52 or the gap between the augers 52 and the shelling rack 51, achieving complete separation of the lotus flesh from the shell and complete shelling of the lotus seeds.

[0042] In some embodiments, reference Figure 6 The secondary feeding device 6 includes a feeding hopper 61, which is arranged below the discharge port of the shelling device 5. A feeding port is provided at one end of the feeding hopper 61 away from the frame 1. The width of the feeding port is adapted to the size of the lotus seeds, so that the lotus seeds fall one by one in the width direction, thereby realizing the control of the falling of the lotus seeds. A feeding assembly 62 is provided below the feeding port, and the feeding assembly 62 can successively transport the lotus seeds in the feeding hopper 61 to the peeling device 7, thereby realizing continuous feeding of the peeling device 7.

[0043] Specifically, the feeding assembly 62 includes a rotatable feeding shaft 621, which can be connected to the drive motor 31 via a gear assembly or a conveyor belt. A feeding tray 622 is coaxially sleeved on the feeding shaft 621. The feeding tray 622 is located below the feeding port and is located within the feed hopper 61. As the lotus seeds rotate with the feeding tray 622, they will not fall from the sides of the feeding tray 622, ensuring that the lotus seeds rotate with the feeding tray 622 and fall from the feed hopper 61 into the peeling device 7. The feeding tray 622 is annularly provided with multiple feeding troughs 623. As the feeding tray 622 rotates, the lotus seeds falling from the feeding port fall into the feeding troughs 623, thereby causing the lotus seeds to rotate with the feeding tray 622 and then enter the peeling device 7.

[0044] In some embodiments, the peeling device 7 includes an intermittently rotatable clamping assembly 71, which is arranged below the discharge port of the secondary feeding device 6. The clamping assembly 71 can be connected to the drive motor 31 through structures such as intermittent cams, so that the clamping assembly 71 can clamp the lotus seeds dropped from the secondary feeding device 6 and rotate intermittently. A rotatable friction wheel 72 is provided between the secondary feeding device 6 and the discharge hopper 8. The friction wheel 72 can be a rubber wheel. The friction wheel 72 is in rolling contact with the lotus seeds on the clamping assembly 71. The friction force generated by the rolling contact between the friction wheel 72 and the lotus seeds on the clamping assembly 71 can destroy the epidermis on the surface of the lotus seeds without damaging the lotus flesh inside the lotus seeds. A water gun assembly 73 is also provided on the frame 1. The outlet direction of the water gun assembly 73 is aligned with the lotus seeds on the clamping assembly 71. The broken epidermis on the lotus seeds can be washed by spraying water, so that the lotus flesh is completely separated from the epidermis, thereby realizing the peeling of the lotus seeds on the clamping assembly 71.

[0045] In some embodiments, there may be two friction wheels 72, including an upper friction wheel and a lower friction wheel. The upper friction wheel and the lower friction wheel are positioned adjacent to each other, and the lower friction wheel is positioned between the upper friction wheel and the discharge hopper 8. The two friction wheels 72 allow the lotus seeds to be peeled twice, ensuring the cleanliness of the peeled lotus seeds. The friction wheels 72 may be made of a soft material such as a sponge. Due to the ability of the friction wheels 72 to deform under force, lotus seeds of varying sizes are subjected to sufficient friction in the peeling device 7, thereby achieving complete peeling of the lotus seeds. Furthermore, the water gun assembly 73 allows the lotus seeds to be completely peeled.

[0046] In some embodiments, the clamping assembly 71 includes a turntable 711 that can rotate intermittently. The turntable 711 can be connected to the drive motor 31 through a structure such as an intermittent cam, so as to rotate intermittently. The turntable 711 is arranged below the discharge port of the secondary feeding device 6 and can directly receive the lotus seeds that fall from the secondary feeding device 6. A plurality of rollers 712 are provided in a ring shape on the turntable 711. A placement groove 714 that matches the shape of the lotus seeds is formed between two adjacent rollers 712. Lotus seeds are placed in the placement groove 714. The placement groove 714 can ensure that the lotus seeds can be clamped during the peeling process and will not slip or be misplaced. At the same time, the lotus seeds can rotate to a certain extent in the placement groove 714. A convex ring can be provided in the middle of the friction wheel 72, and the roller 712 can be provided with an annular groove. The shape of the convex ring is adapted to the shape of the annular groove, so that the friction wheel 72 can be in rolling contact with the lotus seeds in the placement groove 714 while the friction wheel 72 and the roller 712 do not contact each other, thereby preventing the friction wheel 72 from affecting the rotation of the turntable 711, thereby affecting the peeling process of the lotus seeds.

[0047] In some embodiments, the clamping assembly 71 further includes a rotatable blocking roller 713, which can be connected to the drive motor 31 via a gear assembly or a conveyor belt assembly. The blocking roller 713 is coaxially arranged with the turntable 711. A plurality of rollers 712 are annularly arranged around the blocking roller 713, and the rollers 712 are tangential to the blocking roller 713. The rotation of the blocking roller 713 drives the rollers 712 to rotate, thereby causing the dried fruits in the placement groove 714 to roll and rub against the rollers 712, thereby increasing the friction on the dried fruit skin and improving the peeling effect of the peeling device on the dried fruits.

[0048] In some embodiments, reference Figure 7 , the frame 1 is also provided with a water gun assembly 73, the outlet direction of the water gun assembly 73 is aligned with the lotus seeds on the clamping assembly 71, the water gun assembly 73 is intermittently driven, and the intermittent driving member includes a rotatable water change cam 731, and the water change cam 731 can be connected to the drive motor 31 through a gear assembly or a conveyor belt assembly. This is a prior art and will not be described in detail here; the water change cam 731 is connected to a water change lever 732, and the water change lever 732 is provided with a push rod 733 on the side away from the water change cam 731. A fixed cylinder 734 is inserted on the top rod 733, and the top rod 733 can slide in the fixed cylinder 734. A return spring 735 is connected between the bottom of the fixed cylinder 734 and the bottom of the top rod 733. A high-pressure gas tank 736 is connected to the top of the fixed cylinder 734. The high-pressure gas tank 736 stores high-pressure gas. An intermittent water discharge component 737 is provided in the fixed cylinder 734. The fixed cylinder 734 is connected to multiple water spray components 738. The intermittent water discharge component 737 can introduce the water in the high-pressure gas tank 736 into the water spray component 738.

[0049] The water change cam 731 rotates, forcing the water change lever 732 toward the end of the water change cam 731 and causing the water change lever 732 to move upward, away from the end of the water change cam 731. This causes the push rod 733 to slide upward within the fixed barrel 734, thereby moving the intermittent water discharge member 737. High-pressure water from the water pump, under the action of high-pressure gas in the high-pressure gas tank 736, is directed into the water spray member 738. From the water spray member 738, it is sprayed onto the lotus seeds in the storage tank 714, washing the lotus seeds and completely separating the lotus skin from the lotus flesh. When the water change cam 731 is stationary, the return spring 735 causes the push rod 733 to slide downward within the fixed barrel 734, thereby returning the intermittent water discharge member 737 to its original position and preventing water from the water pump from entering the water spray member 738.

[0050] In some embodiments, reference Figure 8The fixed cylinder 734 includes a lifting groove 7341, which is slidably and sealedly connected to the top rod 733. A water drain groove 7342 is provided above the lifting groove 7341, and the water drain groove 7342 is connected to multiple water spray parts 738. A connecting groove 7343 is provided above the water drain groove 7342. The top of the connecting groove 7343 is connected to a high-pressure gas tank 736. A water pump is connected to one side of the connecting groove 7343. A sealing ring platform 7344 is provided between the water drain groove 7342 and the connecting groove 7343; the intermittent water drain component 737 includes a ejector pin 7371, which is coaxially arranged at the top of the ejector rod 733 and can slide in the water drain groove 7342. A steel ball 7372 is provided in the connecting groove 7343, and the steel ball 7372 is sealedly connected to the sealing ring platform 7344.

[0051] When the ejector pin 733 moves upward in the lifting groove 7341, it drives the ejector pin 7371 to slide upward in the water drain groove 7342. The ejector pin 7371 presses against the steel ball 7372, causing the steel ball 7372 to move upward and separate from the sealing ring 7344. At this time, the water flowing out of the water pump flows from the connecting groove 7343 to the water drain groove 7342 under the action of the high-pressure gas in the high-pressure gas tank 736, and flows to the water spraying member 738, and finally sprays to the water in the placement groove 714. When the push rod 733 moves downward in the lifting groove 7341, it will drive the ejector pin 7371 to slide downward in the drain groove 7342. The steel ball 7372 loses the support of the ejector pin 7371. Under the action of gravity and water pressure, the steel ball 7372 moves downward and falls on the sealing ring platform 7344, and is sealed with the sealing ring platform 7344, thereby preventing the water flowing out of the water pump from flowing from the connecting groove 7343 to the drain groove 7342.

[0052] Through the joint action of the water-changing cam 731, the water-changing lever 732, the push rod 733, the fixed cylinder 734, the return spring 735, the high-pressure gas tank 736, the intermittent water discharge component 737 and the water spray component 738, the intermittent communication between the high-pressure gas tank 736 and the water spray component 738 can be achieved, and intermittent water spraying can be achieved. Therefore, without increasing the water pressure in the high-pressure gas tank 736, the instantaneous impact force of the water flow sprayed by the water spray component 738 is enhanced, thereby improving the separation effect between the lotus seed epidermis and the lotus flesh. At the same time, when water flushing is not required, there is no need for water spraying, thereby avoiding the continuous output of water during the processing process, thereby saving water and reducing the processing cost of lotus seeds.

[0053] The specific working principle is as follows:

[0054] Lotus seeds enter the main bucket 21, passing through the auxiliary bucket 22 and the splint bucket 23. The differential cam 24 controls the speed, while the needle stop assembly 25 ensures that only the appropriate amount of lotus seeds enters the conveyor 3 at any one time. The lotus seeds then travel along the conveyor belt 34 to the shelling device 4. During this movement, a drive mechanism 43 drives a cutter 44 in reciprocating motion, cutting the lotus seed shells. Simultaneously, an elastic shell separating member 42 and the conveyor belt 34 compress the lotus seeds, separating the shell from the lotus flesh. The shelled lotus seeds then fall into the shelling device 5. Two augers 52 rotate, driving the lotus seeds toward the secondary feeder 6. Friction between the two augers 52 and the lotus seeds removes any remaining shells, and the seeds then fall into the secondary feeder 6. Lotus seeds fall from the discharge port into the discharge chute 623 of the discharge tray 622. Following the rotation of the tray 622, they eventually enter the clamping assembly 71. The seeds then fall into the placement groove 714 between the two rollers 712 and are secured there. As the turntable 711 rotates, the two friction wheels 72 roll and rub against the lotus seeds, achieving a secondary peeling. Simultaneously, the water gun assembly 73 operates. The water change cam 731, via the water change lever 732, drives the push rod 733 up and down. The intermittent water discharge element 737 controls the intermittent release of water from the high-pressure gas tank 736. The water spray element 738 then rinses the lotus seeds with high-pressure water, achieving a secondary peeling. The peeled lotus seeds are then discharged from the discharge hopper 8, completing the entire process.
