[0002] In the food processing industry, chestnuts, as a nutritious and uniquely flavorful ingredient, are increasingly in demand for deep processing. Opening chestnuts is a crucial step in chestnut processing. For example, when making roasted chestnuts, canned chestnuts, chestnut cakes, and other products, chestnuts need to be opened to improve the efficiency of subsequent processing and product quality.

[0003] Traditional chestnut-opening methods rely heavily on manual labor, requiring workers to use knives or other tools to make incisions in each chestnut individually. This method is not only labor-intensive but also extremely inefficient, making it difficult to meet the demands of large-scale industrial production. Furthermore, manual incision is affected by factors such as the operator's skill level and control of force, making it difficult to maintain consistency in the depth, angle, and position of the incisions.

A spiral feeding rod extending into the inner side of the output end of the feeding hopper is mounted on the bottom of the main shaft. A guide platform is mounted on the top of the processing table below the feeding hopper. An opening box is mounted on the top of the processing table on one side of the guide platform. One end of the guide platform extends into the interior of the opening box and is connected to a feeding guide rail. An inclined guide groove is provided at the center of the guide platform. The inclined guide groove communicates with a horizontal guide groove provided inside the feeding guide rail. Feeding wheels are evenly mounted on the inner walls of the feeding guide rails on both sides of the horizontal guide groove via rotating shafts.

[0006] The top of the processing table at one end of the horizontal guide channel is provided with clamping wheel one and clamping wheel two in parallel. The outer sides of clamping wheel one and clamping wheel two are evenly provided with clamping grooves. Each clamping groove is equipped with an arc-shaped clamping block by a spring. The inner wall of the arc-shaped clamping block is covered with a rubber pad.

[0007] A transmission box is installed at the bottom of the processing table corresponding to the positions of clamping wheel one and clamping wheel two. The transmission box contains intermeshing transmission wheel one and transmission wheel two. A servo motor is installed at the bottom of the transmission box, and the output end of the servo motor is fixedly connected to transmission wheel one.

[0008] An electric lifting rod is installed at one end of the top of the opening box. The output end of the electric lifting rod extends into the interior of the opening box and is equipped with an opening blade. Infrared heating tubes are also evenly arranged at the top of the interior of the opening box. The infrared heating tubes are connected to a controller installed on one side of the processing table through wires.

[0009] Preferably, the first transmission wheel and the first clamping wheel, as well as the second transmission wheel and the second clamping wheel, are coaxially connected, and the inner side of the clamping groove of the first clamping wheel and the second clamping wheel is provided with a hole for fixing the spring, the depth of the hole being less than the length of the spring.

[0015] This utility model provides an opening device for chestnut processing, which has significant advantages over the prior art, as detailed below:

[0016] 1. Through the synergistic action of the spiral feed rod, inclined guide trough, and horizontal guide trough, chestnuts can automatically align and enter the processing flow, reducing manual intervention and significantly improving production efficiency. The automated design not only reduces labor intensity but also decreases the defect rate caused by improper manual operation.

[0017] 2. Before entering the cutting chamber, the chestnuts pass through a heating zone formed by infrared heating tubes inside the open chamber. When the shell temperature rises to 60℃, the difference in thermal expansion between the shell and kernel effectively reduces cutting resistance. This preheating process not only makes the cutting process smoother but also reduces damage to the internal structure of the chestnuts, ensuring their integrity. Each infrared heating tube is equipped with a trapezoidal reflector on its outer side, effectively concentrating heat, improving heating efficiency, and reducing energy consumption. Simultaneously, the insulation jacket further reduces heat loss, making the heating process more energy-efficient and effective.

[0018] 3. Two clamping wheels are provided, each with evenly spaced clamping grooves on its outer side. Inside each groove, an arc-shaped clamping block is spring-loaded, and the inner wall of the arc-shaped clamping block is lined with a rubber pad. Once the chestnut enters the groove, it is tightly encased by the arc-shaped clamping block, ensuring a stable cut when passing the cutting edge. Furthermore, the cutting edge's height can be adjusted by an electric lifting rod, further improving cutting precision and flexibility.

[0019] 4. Stabilizing telescopic rods are installed at the top of the opening housings on both sides of the electric lifting rod output end. The output end of each stabilizing telescopic rod is fixedly connected to the top of the opening blade, further ensuring the stability of the cutting process. In addition, the conveyor belt allows the processed chestnuts to be output promptly, avoiding accumulation and blockage. Attached Figure Description

The support frame 3 is made of L-shaped steel, possessing high strength and stability, and can effectively support the feed hopper 8 and its related components.

[0029] The feed hopper 8 is installed above the support frame 3. The top of the feed hopper 8 has a circular opening for installing the feed motor 6.

[0030] The feed motor 6 is a DC motor, mounted on the top of the feed hopper 8 and secured with bolts. The output end of the feed motor 6 extends into the interior of the feed hopper 8 and is connected to the main shaft 7. The function of the feed motor 6 is to drive the main shaft 7 to rotate, thereby achieving uniform feeding of the chestnuts.

[0031] The main shaft 7 is made of stainless steel, and its length is designed according to the depth of the feed hopper 8. One end of the main shaft 7 is connected to the output end of the feed motor 6, and the other end is equipped with a screw feed rod 4.

[0032] The spiral feed rod 4 is made of stainless steel, and the pitch of the spiral blades is suitable for the size of the chestnuts, with a diameter slightly smaller than the inner diameter of the feed hopper 8. The bottom of the spiral feed rod 4 extends to the inside of the output end of the feed hopper 8, and its function is to evenly push the chestnuts from the bottom of the feed hopper 8 to the open processing area.

[0033] Evenly spaced on the outer side of the main shaft 7 are feeding rods 5. The feeding rods 5 are made of nylon and rotate with the main shaft 7. The function of the feeding rods 5 is to prevent chestnuts from accumulating or clogging during the feeding process, ensuring that the chestnuts can smoothly enter the pushing area of ​​the spiral feed rod 4.

[0034] A guide platform 2 is installed on the top of the processing table 1 below the feed hopper 8. An open box 9 is installed on the top of the processing table 1 on one side of the guide platform 2. One end of the guide platform 2 extends into the interior of the open box 9 and is connected to the feeding guide rail 17. An inclined guide groove 29 is provided in the center of the guide platform 2. The inclined guide groove 29 is connected to the horizontal guide groove 28 provided inside the feeding guide rail 17. Feeding wheels 27 are evenly installed on the inner walls of the feeding guide rail 17 on both sides of the horizontal guide groove 28 through the rotating shaft 26.

[0035] The feed hopper 8 is located at the top of the device and is used to store the materials to be processed. The bottom of the feed hopper 8 has a discharge port through which the materials fall onto the processing table 1 below. The processing table 1 is a horizontal planar structure that provides the basic support for the device.

[0036] A guide platform 2 is installed on top of the processing table 1. The main function of the guide platform 2 is to guide the material falling from the feed hopper 8 into the open box 9. One side of the guide platform 2 is close to the edge of the processing table 1, and the other side extends into the interior of the open box 9. One end of the guide platform 2 is fixed to the processing table 1 by a connecting structure to ensure its stability.

[0037] An open box 9 is installed on top of the processing table 1 on one side of the guide table 2, with its opening facing upwards, to receive materials guided from the guide table 2. The internal space of the open box 9 is large enough to hold a certain amount of material for subsequent processing.

[0038] One end of the guide platform 2 extends into the interior of the open box 9 and is connected to the feeding guide rail 17. The feeding guide rail 17 is located inside the open box 9, and its main function is to guide the material from the guide platform 2 to the processing area. The feeding guide rail 17 consists of two parallel tracks with smooth inner walls to reduce resistance during material transport.

[0039] An inclined guide trough 29 is provided at the center of the guide platform 2. The inclined angle of the inclined guide trough 29 is reasonably designed so that the material can slide smoothly from the guide platform 2 onto the feeding guide rail 17. One end of the inclined guide trough 29 is connected to the surface of the guide platform 2, and the other end extends into the interior of the feeding guide rail 17 and communicates with the horizontal guide trough 28.

[0040] The horizontal guide trough 28 is located inside the feeding guide rail 17, and its two ends are connected to the inclined guide trough 29 and the inner wall of the feeding guide rail 17, respectively. The main function of the horizontal guide trough 28 is to evenly distribute the material sliding down from the inclined guide trough 29 onto the feeding guide rail 17, ensuring that the material can be transported smoothly.

[0041] Feeding wheels 27 are evenly installed on both sides of the inner wall of the feeding guide rail 17 via rotating shafts 26. The feeding wheels 27 are cylindrical with smooth surfaces and can rotate with the rotating shafts 26. The main function of the feeding wheels 27 is to propel the material forward on the feeding guide rail 17, ensuring that the material can be continuously conveyed to the processing area.

[0042] One end of the shaft 26 of the feed roller 27 extends to the top of the feed guide rail 17 and is equipped with a gear 12.

[0043] At one end of the horizontal guide channel 28, the processing table 1 is provided with a clamping wheel 14 and a clamping wheel 19 arranged side by side. The top of the clamping wheel 14 is also provided with a gear 12, and each gear 12 is fixedly connected to the other by a chain 13.

[0044] Both clamping wheel 14 and clamping wheel 29 are evenly provided with clamping grooves 20 on their outer sides. Each clamping groove 20 is fitted with an arc-shaped clamping block 21 through a spring 23. The inner wall of the arc-shaped clamping block 21 is covered with a rubber pad 24.

[0045] One end of the shaft 26 of the feed roller 27 extends to the top of the feed guide rail 17, and a gear 12 is mounted at that end. The main function of the feed roller 27 is to transport materials from one end of the feed guide rail 17 to the other. The feed guide rail 17 provides a stable transmission path for the materials, and its top is designed with a support structure for mounting the gear 12.

[0046] At one end of the horizontal guide channel 28, on the top of the processing table 1, are two clamping wheels, one 14 and the other 19, arranged side by side. Each clamping wheel 14 also has a gear 12 on its top. Each gear 12 is fixedly connected to the others by a chain 13, forming a transmission system. This transmission system ensures that the clamping wheels 14 and 19 rotate synchronously, thereby achieving stable clamping and conveying of the material.

[0047] Clamping grooves 20 are evenly provided on the outer sides of clamping wheel 14 and clamping wheel 19. An arc-shaped clamping block 21 is installed inside each clamping groove 20 via a spring 23. The inner wall of the arc-shaped clamping block 21 is lined with a rubber pad 24 to increase the friction when in contact with the material and prevent the material from sliding.

[0048] A transmission box 34 is installed at the bottom of the processing table 1 at the position corresponding to the clamping wheel 14 and the clamping wheel 2 19. The transmission box 34 is equipped with a transmission wheel 1 35 and a transmission wheel 2 36 that mesh with each other. A servo motor 16 is installed at the bottom of the transmission box 34, and the output end of the servo motor 16 is fixedly connected to the transmission wheel 1 35.

[0049] The transmission wheel 35 and the clamping wheel 14, as well as the transmission wheel 36 and the clamping wheel 19, are all coaxially connected. The clamping grooves 20 of the clamping wheel 14 and the clamping wheel 19 are provided with holes 22 for fixing the spring 23. The depth of the holes 22 is less than the length of the spring 23.

[0050] The transmission housing 34 contains two meshing transmission wheels: a first transmission wheel 35 and a second transmission wheel 36. Both transmission wheels 35 and 36 employ high-precision gear design to ensure smooth and efficient transmission. The meshing method between transmission wheels 35 and 36 is spur gear meshing, which effectively transmits power.

[0051] A servo motor 16 is mounted on the bottom of the transmission housing 34. The servo motor 16 is a high-torque, high-precision servo motor, capable of providing continuous and stable power output. The output end of the servo motor 16 is fixedly connected to the transmission wheel 35 via a coupling, ensuring the reliability and stability of power transmission.

[0052] The transmission wheel 35 and clamping wheel 14, as well as the transmission wheel 36 and clamping wheel 19, are all coaxially connected. Specifically, the transmission wheel 35 and clamping wheel 14 are connected by a transmission shaft 37, and the transmission wheel 36 and clamping wheel 19 are connected by another transmission shaft 38. This coaxial connection effectively reduces energy loss during transmission and improves transmission efficiency.

[0053] Both clamping wheels 14 and 19 have holes 22 inside their clamping grooves 20 for fixing springs 23. The depth of the holes 22 is less than the length of the springs 23, ensuring that the springs 23 can maintain a certain preload after installation. The springs 23 are made of high-strength, high-elasticity materials, which can provide stable clamping force during clamping.

[0054] Start the servo motor 16. The output of the servo motor 16 drives the transmission wheel 35 to rotate through the coupling. The transmission wheel 35 drives the transmission wheel 36 to rotate through spur gear meshing, and then drives the clamping wheel 14 and the clamping wheel 19 to rotate synchronously through the transmission shaft 37 and the transmission shaft 38, respectively.

[0055] As clamping wheels 14 and 19 rotate, chestnuts successively enter the clamping groove 20. With the rotation of clamping wheels 14 and 19, spring 23 is compressed, generating a clamping force that firmly holds the chestnuts within the clamping groove 20. Because the depth of the hole 22 is less than the length of the spring 23, the spring 23 maintains a certain preload during compression, ensuring the stability and reliability of the clamping process.

[0056] An electric lifting rod 30 is installed at one end of the top of the open box 9. The output end of the electric lifting rod 30 extends into the interior of the open box 9 and is equipped with an opening blade 32. Stable telescopic rods 33 are installed at the top of the interior of the open box 9 on both sides of the output end of the electric lifting rod 30. The output end of each stable telescopic rod 33 is fixedly connected to the top of the opening blade 32. The outer wall of the open box 9 is evenly covered with a heat-insulating jacket 31.

[0057] Infrared heating tubes 10 are evenly arranged at the top of the interior of the open box 9. The infrared heating tubes 10 are connected to the controller 18 installed on one side of the processing table 1 through wires.

[0058] Each infrared heating tube 10 is provided with a reflector 11 on its outer side, and the reflector 11 is a trapezoidal structure.

[0059] The overall structure of the opening box 9 is rectangular, with an electric lifting rod 30 installed at one of its top ends. The output end of the electric lifting rod 30 extends into the interior of the opening box 9, and an opening blade 32 is installed at its end. The opening blade 32 is made of a high-hardness material to ensure the accuracy and durability of the cutting process.

[0060] On both sides of the output end of the electric lifting rod 30, and on the left and right sides of the top of the opening housing 9, a stabilizing telescopic rod 33 is installed. The output end of each stabilizing telescopic rod 33 is firmly connected to the top of the opening blade 32 through a fixed connecting device, thereby providing stable support during the cutting process and preventing the opening blade 32 from shifting during movement.

[0061] The outer wall of the open box 9 is evenly covered with an insulating jacket 31. The insulating jacket 31 is made of high-efficiency insulation material, which can effectively reduce heat loss and maintain the stability of the temperature inside the box, making it suitable for scenarios where the internal items need to be heated.

[0062] In addition, infrared heating tubes 10 are evenly arranged at the top of the interior of the open housing 9. Each infrared heating tube 10 is connected to a controller 18 installed on one side of the processing table 1 via a wire. The controller 18 has temperature setting and adjustment functions, and can accurately control the heating temperature of the infrared heating tube 10 according to actual needs.

[0063] Each infrared heating tube 10 is equipped with a reflector 11 on its outer side. The reflector 11 adopts a trapezoidal structure design, which can effectively reflect the heat generated by the infrared heating tube 10 to the interior of the open box 9, thereby improving heating efficiency. The trapezoidal structure of the reflector 11 not only expands the heat radiation area, but also ensures the uniformity of heat distribution.

[0064] The processing table 1 at the output end of the open box 9 is equipped with a conveyor belt 15, and a transmission motor 25 is installed on one side of the processing table 1 at the position corresponding to the position of the conveyor belt 15. The drive shaft of the transmission motor 25 is fixedly connected to the transmission shaft of the conveyor belt 15.

[0065] The conveyor belt 15 is located in the center of the processing table 1, and its length and width are designed according to actual processing requirements. The material of the conveyor belt 15 can be high-strength rubber or plastic that is wear-resistant and high-temperature resistant to ensure that it is not easily damaged during long-term use.

[0066] On one side of the processing table 1, a conveyor motor 25 is installed at the position corresponding to the conveyor belt 15. The function of the conveyor motor 25 is to provide power to drive the conveyor belt 15. The model and power of the conveyor motor 25 are selected according to the size of the conveyor belt 15 and the required transmission speed.

[0067] The drive shaft of the conveyor motor 25 is connected to the conveyor shaft of the conveyor belt 15 via a fixed connection device.

[0068] In this embodiment, the electric lifting rod 30 drives the opening blade 32 downward to a preset height according to a preset program. After the chestnuts to be processed are poured into the feeding hopper 8, the feeding motor 6 is started, which drives the main shaft 7 to rotate. The material-pushing rod 5 on the outside of the main shaft 7 rotates with the main shaft, dispersing the accumulated chestnuts and preventing blockage. The spiral feeding rod 4 at the bottom of the main shaft 7 rotates synchronously, using the pushing action of the spiral blades to evenly feed the chestnuts from the output end at the bottom of the feeding hopper 8. After being pushed by the spiral feeding rod 4, the chestnuts fall into the guide platform 2 at the top of the processing table 1. The inclined guide groove 29 at the center of the guide platform 2 is at a certain angle, and the chestnuts slide down along the inclined guide groove 29 and enter the horizontal guide groove 28 inside the feeding guide rail 17, completing the initial conveying.

[0069] Feeding wheels 27 on both sides of the feeding guide rail 17 are mounted on the inner wall of the guide rail via rotating shafts 26. Gear 12 at the top of the rotating shaft 26 is connected to gear 12 at the top of clamping wheel 14 via a chain 13. When clamping wheel 14 rotates, it drives gear 12 of the feeding wheel 27 to rotate via the chain 13, causing the feeding wheel 27 to rotate synchronously. The chestnuts in the horizontal guide trough 28 move along the feeding guide rail 17 towards clamping wheel 14 and clamping wheel 19 under the push of the feeding wheels 27.

[0070] The infrared heating tube 10 at the top of the open box 9 is activated under the control of the controller 18, emitting infrared radiation to heat the chestnuts. The trapezoidal reflector 11 on the outside of the infrared heating tube 10 concentrates and reflects the heat onto the surface of the chestnuts, improving heating efficiency; the heat-insulating jacket 31 on the outer wall of the open box 9 reduces heat loss, allowing the chestnut shell temperature to rise rapidly to 60°C, creating a thermal expansion difference between the shell and the kernel, reducing subsequent cutting resistance.

[0071] The servo motor 16 at the bottom of the processing table 1 starts, driving the transmission wheel 35 inside the transmission housing 34 to rotate. The transmission wheel 35 meshes with the transmission wheel 36, causing them to rotate synchronously. The transmission wheel 35 and the clamping wheel 14, and the transmission wheel 36 and the clamping wheel 19 are coaxially connected via a transmission shaft, so the clamping wheel 14 and the clamping wheel 19 rotate synchronously in opposite directions. When the chestnut enters the clamping groove 20 outside the clamping wheel 14 and the clamping wheel 19, the spring 23 inside the groove pushes the arc-shaped clamping block 21 to clamp the chestnut (the spring 23 is installed in the hole 22 inside the clamping groove 20, the hole depth is less than the spring length, ensuring stable clamping force). The rubber pad 24 on the inner wall of the arc-shaped clamping block 21 increases friction to prevent the chestnut from slipping and achieves precise positioning.

[0072] When the clamping wheels 14 and 19 rotate the heated chestnut wheel to below the opening blade 32, the top of the chestnut contacts the opening blade 32, and the chestnut shell is successfully cut open. The clamping wheels 14 and 19 continue to rotate, causing the chestnut with the opening to fall out of the clamping groove 20 and onto the conveyor belt 15 at the output end of the opening box 9. The conveyor motor 25 drives the conveyor belt 15 to transport the chestnuts to the subsequent processing area, realizing continuous production.
