[0001] The present invention relates to the technical field of intelligent food processing, and in particular to a barbecue grilling device and a barbecue grilling method. Background Art

[0002] Barbecue is a common dish in China with a unique flavor and a long history. Barbecue includes pork, beef, vegetables, seafood, etc. However, in the existing barbecue process, most of the ingredients need to be sprinkled manually, which has a low degree of automation, consumes manpower, and reduces the efficiency of barbecue.

[0003] For example, patent publication number CN212678956U, titled "A Barbecue Device," describes a device comprising a barbecue body and a skewer holder. The device body is equipped with a rotating assembly, and the skewer holder is transmission-connected to the rotating assembly. The skewer holder is used to hold the unattached end of the skewer. The rotating assembly rotates, thereby rotating the skewer holder, which in turn rotates the skewer, causing the food on the skewer to rotate accordingly, achieving automatic flipping of the barbecued meat.

[0004] During the grilling process, barbecue seasoning needs to be sprinkled on the surface of the food to improve the taste and flavor of the grilled food. However, in the above-mentioned document, although the food can be automatically turned over during the grilling process to ensure uniform heating of the food, people still need to manually sprinkle the barbecue seasoning on the surface of the food, resulting in uneven spreading of the seasoning, which affects the taste of the food. In addition, manual spreading of the seasoning is time-consuming and labor-intensive, which reduces the grilling efficiency of the food. Summary of the Invention

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-Figure 4 As shown, a barbecue grilling device includes a box body 1, which is rectangular and has an open top. Moving wheels (not shown in the figure) are evenly installed on the bottom of the box body 1 to facilitate the movement of the entire device. A plurality of equidistantly arranged electric heating tubes 7 are installed in the box body 1, and the electric heating tubes 7 are used to provide a heat source for grilling the meat. A plurality of barbecue skewers 6 are installed on the top of the box body 1 along its length, and the plurality of barbecue skewers 6 are equidistantly arranged. A first rotating assembly for driving the barbecue skewers 6 to rotate is installed on the box body 1, and the first rotating assembly includes a motor 17, a plurality of support blocks 5 and a plurality of fixed blocks 11. The plurality of support blocks 5 are fixedly installed on the edge of the front side of the top of the box body 1, and the plurality of support blocks 5 are equidistantly arranged along the length of the box body 1. As shown Figure 2 As shown, multiple fixing blocks 11 are fixedly mounted on the top rear edge of the housing 1, corresponding one-to-one with the multiple support blocks 5. A driven shaft 12 is rotatably mounted on the fixing blocks 11. The driven shaft 12 extends horizontally through the fixing blocks 11. A mounting tube 14 is coaxially fixedly mounted on one end of the driven shaft 12. The mounting tube 14 is removably connected to the corresponding skewer 6. A plurality of key slots 16 are defined along the circumference of one end of the skewer 6. The inner wall of the mounting tube 14 is fixedly mounted along its circumference with a plurality of flat keys 15. The flat keys 15 correspond to and slide in contact with the key slots 16. By inserting the end of the skewer 6 with the key slot 16 into the corresponding mounting tube 14 and sliding the flat keys 15 inside the mounting tube 14 into the key slot 16, the mounting tube 14 drives the corresponding skewer 6 in rotation. Simultaneously, by disengaging the key slot 16 on the skewer 6 from the flat keys 15 inside the mounting tube 14, the skewer 6 can be easily removed. A circular stopper plate is fixedly mounted on the end of the skewer 6 away from the mounting tube 14. A placement slot is formed on the top of the support block 5 to fit the stopper plate. The stopper plate is placed in the corresponding placement slot, and a ball bearing is installed in the placement slot to reduce friction between the stopper plate and the placement slot.

[0028] like Figure 3 and Figure 4As shown, a mounting shell 2 is fixedly mounted on the rear side of the housing 1. A motor 17 is fixedly mounted in the center of the bottom of the mounting shell 2. The output shaft of the motor 17 passes through the mounting shell 2 and is fixedly mounted with a driving shaft 18. The other end of the driving shaft 18 is rotatably connected to the housing 1. A transmission assembly is mounted between the other end of the driven shaft 12 and the driving shaft 18. The transmission assembly includes a driving pulley 19 and multiple driven pulleys 13. The driving pulley 19 is fixedly mounted on the outer circumference of the driving shaft 18. The multiple driven pulleys 13 are respectively fixedly mounted on one end of the corresponding driven shaft 12. A common transmission belt 20 is mounted between the driving pulley 19 and the multiple driven pulleys 13. The rear side of the housing 1 is coated with a high-temperature resistant material to ensure that the transmission belt 20 operates stably and for a long time in high-temperature environments. In addition, the diameters of the driving pulley 19 and the driven pulley 13 can be adjusted according to actual needs to control the rotation speed of the barbecue skewers 6 to meet different barbecue cooking requirements. The driven pulley 13 can be a pulley or a sprocket. If the driven pulley 13 is a pulley, the transmission belt 20 can be a belt. When the driven wheel 13 is a sprocket, the transmission belt 20 is a chain.

[0029] The motor 17 drives the driving wheel 19 to rotate through the driving shaft 18, and the driving wheel 19 drives multiple driven wheels 13 to rotate synchronously through the transmission belt 20. The driven wheels 13 drive the driven shaft 12 to rotate, so that the mounting cylinder 14 and the barbecue skewers 6 rotate synchronously, achieving uniform heating of the barbecue, avoiding the inconvenience and low efficiency of traditional manual flipping of the barbecue.

[0030] like Figure 1 and Figure 3 As shown, a support assembly is symmetrically mounted on one side of the box body 1, and a supporting plate 8 is fixedly mounted on the top of the supporting assembly. A plurality of material storage slots 9 are fixedly mounted on the top of the supporting plate 8 along its length direction. The plurality of material storage slots 9 correspond to the plurality of barbecue skewers 6 one by one, and the material storage slots 9 are used to store barbecue seasonings. Figure 6 As shown, a feeding port 43 is provided at the bottom of the storage tank 9, which passes through the supporting plate 8 downward, and the bottom surface of the feeding port 43 is flush with the bottom surface of the supporting plate 8. A cover 10 adapted to the top of the storage tank 9 is installed to prevent other impurities from falling into the storage tank 9.

[0031] A control assembly for opening or closing the feeding port 43 of the material storage trough 9 is installed between the supporting plate 8 and the box body 1. The first rotating assembly drives the barbecue skewers 6 to rotate and opens the material storage trough 9 through the control assembly, thereby sprinkling barbecue seasoning on the surface of the barbecue. Figure 5 and Figure 6As shown, the control assembly includes a drive assembly and two baffles 32, which are slidably mounted on the bottom of the carrier plate 8. T-slots 42 are symmetrically defined along the length of the bottom of the carrier plate 8. Guide blocks mate with the T-slots 42, fixedly mounted on either side of the baffles 32. These guide blocks slidably engage the corresponding T-slots 42, facilitating stable sliding of the baffles 32 along the bottom of the carrier plate 8. Each baffle 32 is equidistantly defined with multiple notches 33, which mate with corresponding feed openings 43 of the hopper 9. The drive assembly drives the two baffles 32 toward or away from each other. This movement causes the multiple notches 33 to shift or connect with the corresponding feed openings 43 of the hopper 9, thereby closing or opening the feed openings 43. This allows for automatic seasoning distribution during the barbecue process, avoiding the uneven distribution of seasonings caused by manual application and enhancing the barbecue's flavor. At the same time, it saves manpower and improves the efficiency of barbecue baking.

[0032] like Figure 5 and Figure 6 As shown, the drive assembly includes a reciprocating assembly and two connecting plates 34. The two connecting plates 34 are symmetrically fixedly mounted on the bottom rear side of the carrier plate 8. A connecting shaft 35 is horizontally passed through the connecting plates 34 and is rotatably connected to the connecting plates 34. A first gear 37 is fixedly sleeved on one end of the connecting shaft 35. A first rack 38 is fixedly mounted on the rear side of the baffle 32, and the first rack 38 meshes with the corresponding first gear 37. A second gear 36 is fixedly mounted on the other end of the connecting shaft 35. The reciprocating assembly drives the second gear 36 to rotate, thereby driving the corresponding first gear 37 to rotate through the connecting shaft 35. The first gear 37 and the first rack 38 move, and the first rack 38 drives the corresponding baffle 32 to move, so that the multiple notches 33 of the baffle 32 are respectively misaligned or connected with the corresponding discharge openings 43 of the storage trough 9.

[0033] like Figure 5 As shown, a mounting plate 41 is symmetrically fixedly mounted on the bottom of the carrier plate 8, and a limit rod 40 is slidably mounted on the mounting plate 41. The limit rod 40 is horizontally inserted into the mounting plate 41, and one end of the limit rod 40 is fixedly connected to the corresponding first rack 38. A spring 39 is sleeved on the outer periphery of the limit rod 40, one end of the spring 39 is fixedly connected to the corresponding first rack 38, and the other end of the spring 39 is fixedly connected to the corresponding mounting plate 41. This prevents the baffle 32 from moving after the entire moving device is subjected to bumps.

[0034] like Figure 4 、 Figure 7 and Figure 8As shown, the reciprocating assembly includes a rectangular block 21, which is fixedly mounted on the inner side of the mounting shell 2. A slide groove 44 is vertically opened on the side of the rectangular block 21 close to the housing 1. A reciprocating screw 22 is rotatably mounted in the slide groove 44. The reciprocating screw 22 is arranged vertically, and the two ends of the reciprocating screw 22 are polished rod segments. The polished rod segments at both ends of the reciprocating screw 22 are rotatably inserted into the rectangular block 21. The polished rod segment at the bottom of the reciprocating screw 22 passes downward through the rectangular block 21 and is fixedly sleeved with a first bevel gear 24. A second bevel gear 25 is fixedly mounted on the outer periphery of the driving shaft 18, and the second bevel gear 25 meshes with the first bevel gear 24. The outer periphery of the reciprocating screw 22 is threadedly connected to a slider 23, which is slidably connected to the slide groove 44. Sliding rods 46 are symmetrically fixedly installed on the slider 23, and vertical through grooves 45 are opened on both sides of the rectangular block 21. The sliding rods 46 pass through the corresponding through grooves 45 and are fixedly installed with the second rack 30. The second rack 30 is perpendicular to the sliding rods 46, and the second rack 30 engages with the corresponding second gear 36 when in contact.

[0035] like Figure 4 and Figure 8 As shown, the support assembly includes a rotating cylinder 26 and a threaded rod 27. The rotating cylinder 26 is rotatably mounted on the bottom of the mounting shell 2. A base 47 is symmetrically fixedly mounted on the bottom of the mounting shell 2. The bottom of the rotating cylinder 26 is inserted into the corresponding base 47 and is rotatably connected to the corresponding base 47, thereby improving the stability of the rotating cylinder 26 during rotation. The bottom of the threaded rod 27 is threadedly connected to the rotating cylinder 26, and the top of the threaded rod 27 is fixedly connected to the supporting plate 8. A second rotating assembly is installed on the housing 1 to drive the rotating cylinder 26 to rotate. The second rotating assembly drives the rotating cylinder 26 to rotate. The rotating cylinder 26 drives the threaded rod 27 to rise and fall, and the threaded rod 27 drives the supporting plate 8 to rise and fall. When the supporting plate 8 descends, the distance between the material storage trough 9 and the barbecue skewers 6 is reduced, thereby reducing the impact of external wind on the falling trajectory of the seasoning and improving the accuracy of the seasoning landing on the barbecue. After the supporting plate 8 rises, it prevents the supporting plate 8 from obstructing the operation of the barbecue personnel. The distance between the supporting plate 8 and the electric heating tube 7 is increased, and the bottom surfaces of the supporting plate 8 and the baffle 32 are coated with high-temperature resistant materials, thereby protecting the supporting plate 8 and the baffle 32 and preventing the supporting plate 8 from being damaged by the electric heating tube 7 for a long time.

[0036] like Figure 4 and Figure 8As shown, the second rotating assembly includes a worm gear 29 and a worm 28. Worm gear 28 is rotatably mounted on housing 1, with the other end of worm gear 28 rotatably connected to mounting housing 2. Worm gear 29 is fixedly mounted on the outer periphery of rotating cylinder 26, and a third gear 31 is fixedly mounted on the outer periphery of worm gear 29. When slider 23 drives second rack 30 to reciprocate up and down, second rack 30 engages with third gear 31, driving third gear 31 to rotate. The rotation of third gear 31 drives worm gear 29 through worm gear 28, which in turn drives the corresponding rotating cylinder 26 to rotate.

[0037] like Figure 1 and Figure 7 As shown, a control panel 3 is fixedly mounted on one side of the mounting housing 2. The control panel 3 has a built-in PLC controller and is electrically connected to the motor 17 and the electric heating tube 7. The PLC controller 3 is embedded with a PLC control program. When the barbecue is finished and the slider 23 moves to the bottom of the chute 44, the control panel 3 turns off the motor 17 and the electric heating tube 7. The heating power of the electric heating tube 7 can also be controlled via the control panel 3 to adapt to different barbecue temperatures. A buzzer (not shown) is fixedly mounted on the mounting housing 2 and is electrically connected to the control panel 3. When the motor 17 and the motor 17 heat tube are turned off, the barbecue is finished, and the control panel 3 controls the buzzer to sound, reminding the griller to remove the skewers 6.

[0038] like Figure 1 As shown, the bottom of the housing 1 is opened, into which a collection box 4 is slidably mounted. Both sides of the collection box 4 are slidably connected to the inner wall of the housing 1. The collection box 4 collects dropped seasonings and oil dripping from the barbecue process, preventing them from adhering to the bottom of the housing 1 and making them difficult to clean. A handle is fixedly mounted on the front of the collection box 4, which can be pulled outward to separate the collection box 4 from the housing 1, making it easier to clean.

[0039] A barbecue grilling method, wherein the barbecue grilling method uses the barbecue grilling device described above, and the barbecue grilling method comprises the following steps: S1: Install the barbecue skewer 6. Put the barbecued meat on the barbecue skewer 6. Then align the key slot 16 on the barbecue skewer 6 filled with barbecued meat with the flat key 15 in the corresponding mounting tube 14. Then insert the barbecue skewer 6 into the corresponding mounting tube 14. At the same time, the flat key 15 slides into the corresponding key slot 16. Place the end of the barbecue skewer 6 away from the mounting tube 14 on the corresponding support block 5. This completes the installation of the barbecue skewer 6.

[0040] S2: Grilling begins. The motor 17 and the electric heating tube 7 are started simultaneously. The electric heating tube 7 heats the meat on the grill skewer 6 to grill. The motor 17 drives the driving wheel 19 to rotate via the driving shaft 18. The driving wheel 19 drives the multiple driven wheels 13 to rotate via the transmission belt 20. The driven wheels 13 drive the driven shaft 12 to rotate. The driven shaft 12 drives the grill skewer 6 to rotate via the mounting tube 14. The rotation of the grill skewer 6 drives the meat on the periphery thereof to be evenly heated.

[0041] When the two second racks 30 move upward and are out of contact with the corresponding third gear 31, the distance between the supporting plate 8 and the skewers 6 is minimized, thereby reducing the influence of external wind force on the falling trajectory of the barbecue seasoning and improving the accuracy of the barbecue seasoning falling on the barbecue.

[0042] S4: Spreading: When the two second racks 30 move upward and disengage from the corresponding third gear 31 respectively, the two second racks 30 just contact and mesh with the corresponding second gear 36, so that the two second racks 30 continue to move upward and drive the corresponding second gear 36 to rotate respectively, the second gear 36 drives the connecting shaft 35 to rotate, the connecting shaft 35 drives the first gear 37 to rotate, and the first gear 37 drives the first rack 38 to move, so that the two first racks 38 drive the two baffles 32 to move back to back, and the two baffles 32 move back to back and drive multiple notches 33 to connect with the corresponding discharge port 43 of the storage trough 9, thereby opening the discharge port 43 of the storage trough 9. After the discharge port 43 of the storage trough 9 is opened, the barbecue seasoning in the storage trough 9 is sprinkled from the discharge port 43 to the surface of the barbecue.

[0043] S5: Close the discharge port 43 of the material storage trough 9: When the barbecue skewers 6 drive the barbecue to rotate one circle and the barbecue seasoning is evenly sprinkled on the periphery of the barbecue, the reciprocating screw 22 drives the slider 23 to move downward, and the downward movement of the slider 23 drives the two second racks 30 to move downward. The two second racks 30 respectively drive the corresponding second gears 36 to rotate, and the second gear 36 drives the first gear 37 to rotate through the connecting shaft 35. The first gear 37 drives the first rack 38 to move, so that the two first racks 38 drive the two baffles 32 to move toward each other. The two baffles 32 move toward each other and respectively drive multiple notches 33 to be misaligned with the discharge port 43 of the corresponding material storage trough 9, thereby closing the discharge port 43 of the material storage trough 9.

[0044] S6: The supporting plate 8 is reset. When the two second racks 30 are disengaged from the corresponding second gears 36 during the process of moving downward, the two second racks 30 are engaged with the corresponding third gears 31 respectively. The rotation of the third gear 31 drives the corresponding worm 28 to rotate. The worm 28 drives the corresponding worm wheel 29 to rotate. The worm wheel 29 drives the corresponding rotating cylinder 26 to rotate. The rotation of the rotating cylinder 26 drives the supporting plate 8 to rise through the threaded rod 27. When the supporting plate 8 rises to the highest point, the second rack 30 is disengaged from the third gear 31.

[0045] S7: Power off: After the second rack 30 is disengaged from the third gear 31, the slider 23 continues to move downward. When the slider 23 moves to the bottom of the slide 44, the controller 3 controls the motor 17 and the electric heating tube 7 to turn off. At this time, the grilling of the barbecue is also ended, and the barbecue skewer 6 can be removed.

[0046] Working principle: In the initial state, the slider 23 is located at the lowest end of the slide 44. At this time, the notch 33 on the baffle 32 is misaligned with the discharge port 43 of the storage trough 9, and the distance between the supporting plate 8 and the box body 1 is the farthest.

[0047] First, put the barbecued meat on the barbecue skewer 6, then align the key groove 16 on the barbecue skewer 6 filled with barbecued meat with the flat key 15 in the corresponding mounting tube 14, and then insert the barbecue skewer 6 into the corresponding mounting tube 14. At the same time, the flat key 15 slides into the corresponding key groove 16, and the end of the barbecue skewer 6 away from the mounting tube 14 is placed on the corresponding support block 5, thereby completing the installation of the barbecue skewer 6.

[0048] The motor 17 and the electric heating tube 7 are started simultaneously through the control panel 3. The electric heating tube 7 heats the meat on the barbecue skewers 6 to be grilled. The motor 17 drives the driving wheel 19 to rotate through the driving shaft 18. The driving wheel 19 drives multiple driven wheels 13 to rotate through the transmission belt 20. The driven wheels 13 drive the driven shaft 12 to rotate. The driven shaft 12 drives the barbecue skewers 6 to rotate through the mounting tube 14. The rotation of the barbecue skewers 6 drives the barbecue meat on the periphery thereof to be evenly heated. There is no need to manually flip the barbecue skewers 6, thereby saving manpower and improving the efficiency of barbecue grilling.

[0049] When the driving shaft 18 rotates, the second bevel gear 25 is driven to rotate, and the second bevel gear 25 drives the first bevel gear 24 to rotate. The first bevel gear 24 drives the reciprocating screw 22 to rotate. The reciprocating screw 22 drives the slider 23 to move upward, and the slider 23 drives the two second racks 30 to move upward. When the two second racks 30 move upward, they respectively engage with the corresponding third gear 31 when they contact and mesh, and drive the corresponding third gear 31 to rotate. The rotation of the third gear 31 drives the corresponding worm 28 to rotate, and the worm 28 drives the worm wheel 29 to rotate. The worm wheel 29 drives the rotating cylinder 26 to rotate. The rotating cylinder 26 drives the threaded rod 27 to move downward, and the threaded rod 27 drives the carrying plate 8 to move downward. When the two second racks 30 move upward and disengage from the corresponding third gear 31 respectively, the distance between the carrying plate 8 and the barbecue skewers 6 is minimized, thereby reducing the influence of external wind force on the falling trajectory of the barbecue seasoning and improving the accuracy of the barbecue seasoning falling on the barbecue.

[0050] When the two second racks 30 move upward and disengage from the corresponding third gear 31 respectively, the two second racks 30 just contact and mesh with the corresponding second gear 36, so that the two second racks 30 continue to move upward and drive the corresponding second gear 36 to rotate respectively, the second gear 36 drives the connecting shaft 35 to rotate, the connecting shaft 35 drives the first gear 37 to rotate, and the first gear 37 drives the first rack 38 to move, so that the two first racks 38 drive the two baffles 32 to move back to back, and the two baffles 32 move back to back and drive the multiple notches 33 to connect with the corresponding discharge ports 43 of the storage trough 9, thereby opening the discharge port 43 of the storage trough 9. After the discharge port 43 of the storage trough 9 is opened, the barbecue seasoning in the storage trough 9 is sprinkled from the discharge port 43 to the surface of the barbecue skewered on the outer periphery of the corresponding barbecue skewer 6.

[0051] When the skewers 6 rotate the meat one full circle and the barbecue seasoning is evenly spread around the meat, the reciprocating screw 22 drives the slider 23 downward, which in turn drives the two second racks 30 downward. The two second racks 30 respectively drive the corresponding second gears 36 to rotate. The second gears 36 drive the first gear 37 to rotate via the connecting shaft 35. The first gear 37 drives the first rack 38 to move, thereby driving the two first racks 38 to move the two baffles 32 toward each other. The two baffles 32 move toward each other, causing the multiple notches 33 to shift with the corresponding feed openings 43 of the material storage trough 9, thereby closing the feed opening 43 of the material storage trough 9. This achieves automatic spreading of seasoning during the barbecue process, avoids uneven spreading caused by manual spreading, and improves the taste of the barbecue. This saves manpower and improves the efficiency of barbecue.

[0052] As the two second racks 30 disengage from their corresponding second gears 36 during downward movement, they mesh with their corresponding third gears 31. The rotation of the third gear 31 drives the corresponding worm 28, which in turn drives the corresponding worm wheel 29, which in turn drives the corresponding rotating cylinder 26. The rotating cylinder 26, through the threaded rod 27, drives the supporting plate 8 upward. When the supporting plate 8 reaches its highest point, the second racks 30 disengage from the third gear 31. The slider 23 then continues to move downward. When the slider 23 reaches the bottom of the chute 44, the controller 3 controls the motor 17 and the electric heating tube 7 to turn off. This concludes the grilling process, allowing the skewers 6 to be removed. This automates and maximises the efficiency of the grilling process, improving grilling efficiency.

[0053] Thus, the first rotating assembly of the present invention rotates the skewers 6 while simultaneously opening the feed opening 43 of the material storage trough 9 via the control assembly, thereby evenly distributing the material onto the surface of the meat. Simultaneously, the first rotating assembly rotates the skewers 6 while also raising and lowering the carrier plate 8 via the reciprocating assembly, in conjunction with the second rotating assembly and the support assembly, thereby improving the accuracy of the material distribution. The entire grilling process not only rotates the meat, ensuring even heating, but also automatically distributes the material evenly onto the surface of the meat during its rotation, enhancing the taste and flavor of the meat. Furthermore, manual intervention is reduced throughout the entire process, automating the grilling process and improving grilling efficiency.
