A heating component is installed in the drying oven 1. A circulating conveying mechanism 2 is also installed inside the drying oven 1, and the loading and unloading ends of the circulating conveying mechanism 2 extend to the outside of the drying oven 1. A plurality of hoisting mechanisms 3 are installed on the circulating conveying mechanism 2, and the circulating conveying mechanism 2 can drive the plurality of hoisting mechanisms 3 to circulate and convey. The hoisting mechanism 3 includes a suspension component, a rotation driving component, and a hook 33. The hook 33 is installed below the circulating conveying mechanism 2 through the suspension component. The rotation driving component can drive the suspension component and the hook 33 to rotate synchronously during the process of the suspension component and the hook 33 circulating and conveying with the circulating conveying mechanism 2. The rotation driving component can also drive the hook 33 to flip and move at the bottom of the suspension component when the suspension component and the hook 33 are conveyed to the unloading end of the circulating conveying mechanism 2, so that the opening of the hook 33 faces downward. When the drying equipment for kelp processing is working, the multiple hoisting mechanisms 3 thereon are driven to move cyclically through the circulating conveying mechanism 2. When the hoisting mechanism 3 moves to the loading position at the outer end of the circulating conveying mechanism 2, the kelp is hung on the hook 33. Then the circulating conveying mechanism 2 drives the hook 33 and the kelp to move and transport into the drying box 1. The kelp is gradually heated and dried by the heating component in the drying box 1. At the same time, the rotating driving component drives the suspension component and the hook 33 to rotate synchronously, so that the hook 33 drives the kelp to rotate synchronously during the moving and conveying process, so that the kelp is heated more evenly. Evenly; until the circular conveying mechanism 2 drives the hook 33 and the kelp to move and transport in the drying box 1 for one circle, the kelp drying process is completed, and then the hook 33 and the kelp move to the unloading end of the circular conveying mechanism 2, and the rotary driving component drives the hook 33 to flip and move at the bottom of the suspension component, so that the opening of the hook 33 faces downward, so that the kelp suspended on the hook 33 can automatically slide down, and the automatic unloading of the kelp is realized; then the hook 33 moves to the loading position again, and then the new kelp is suspended on the hook 33 for transportation and drying, and the kelp can be continuously dried by reciprocating in sequence; Through the cooperation of the drying box 1, the circulating conveying mechanism 2 and the multiple lifting mechanisms 3, the kelp is dried continuously, which can significantly improve the kelp drying efficiency and is beneficial to the drying process of large quantities of kelp. By driving the hook 33 to rotate during the kelp conveying and drying process, the kelp being conveyed can be driven to rotate, so that the kelp is heated more evenly, thereby improving the drying effect of the kelp. By driving the hook 33 to flip to a state with the opening facing downward during unloading, the automatic unloading of the kelp can be realized, making the kelp unloading process more convenient and quick.

Example 3

[0025] See also Figures 1 - 3 As shown, the difference between this embodiment and the above embodiment is that the circulating conveying mechanism 2 includes a bracket 21, a plurality of sprockets 23 are rotatably mounted on the outer ring of the upper end of the bracket 21, a conveying chain 24 is drive-mounted on the outer ring of the sprocket 23, a motor 22 is fixedly mounted on the top of the bracket 21, an output end of the motor 22 is drive-connected with one of the sprockets 23, a plurality of equally spaced conveying boxes 25 are fixedly mounted on the outer ring of the conveying chain 24, and a hoisting mechanism 3 is mounted on the bottom end of the conveying box 25; Among them, the conveying chain 24 is fixedly connected to the side of the conveying box 25 through corresponding chain links. When the circulating conveying mechanism 2 works, the motor 22 drives the sprocket 23 connected thereto to rotate. When the sprocket 23 rotates, it can drive the conveying chain 24 to move in a cycle, so that the conveying chain 24 drives a plurality of conveying boxes 25 connected thereto to move in a synchronous cycle, and then the conveying box 25 drives the hoisting mechanism 3 and the kelp below to move in a cycle.

[0026] Furthermore, a track frame 26 is fixedly installed at the top of the bracket 21. A through groove 27 is provided at the bottom of the track frame 26. A plurality of rollers 29 corresponding to the conveying boxes 25 one by one are installed inside the track frame 26 in a rolling manner. A connecting rod 28 is rotatably connected to the roller 29. The lower end of the connecting rod 28 passes through the through groove 27 and extends below the track frame 26, and the bottom end of the connecting rod 28 is fixedly connected to the top end of the conveying box 25. When the conveying box 25 moves, the conveying box 25 can drive the roller 29 to roll forward along the track frame 26 through the connecting rod 28. Through the cooperation of the track frame 26, the connecting rod 28 and the roller 29, the conveying box 25 is supported assistantly, which can improve the stability of the conveying box 25 during installation and moving conveyance, prevent the conveying box 25 from deflecting downward under the gravity of the kelp, and ensure that the conveying box 25 and the kelp can move and convey normally. Embodiment 4

[0027] Please refer to Figure 1 、 Figure 2 As shown, the difference between this embodiment and the above embodiment is that the suspension assembly includes a suspension rod 31. The suspension rod 31 is rotatably installed at the bottom end of the conveying box 25. An installation frame 32 is fixedly installed at the bottom end of the suspension rod 31. An installation shaft 312 is rotatably installed on the installation frame 32. A hook 33 is fixedly installed on the installation shaft 312. When the conveying box 25 moves forward driven by the conveying chain 24, the conveying box 25 drives the suspension rod 31 and the hook 33 below to move synchronously, so that the hook 33 drives the kelp to move and convey for drying. Embodiment 5

[0028] Please refer to Figures 1 - 9As shown in the figure, the difference between this embodiment and the above embodiment is that the rotation drive assembly includes a rotating shaft 34, a transmission gear 36, a transmission gear ring 37 and a locking unit. The rotating shaft 34 is rotatably installed at the axial center position of the suspension rod 31. A driven gear 35 is fixedly installed at the top end of the rotating shaft 34. The transmission gear ring 37 is fixedly installed on the inner wall of the lower end of the track frame 26. The transmission gear 36 is rotatably installed inside the conveying box 25, and both ends of the transmission gear 36 are meshed and drivingly connected with the transmission gear ring 37 and the driven gear 35 respectively. The locking unit can lock and fix the rotating shaft 34 and the suspension rod 31 when the hoisting mechanism 3 is conveyed along with the circulating conveying mechanism 2, and when the hoisting mechanism 3 is conveyed to the blanking position, the locking unit can release the locking between the rotating shaft 34 and the suspension rod 31 and lock and fix the suspension rod 31 and the conveying box 25; The bottom end of the rotating shaft 34 extends above the mounting shaft 312, and a transmission bevel gear 321 is fixedly installed at the bottom end of the rotating shaft 34. A driven bevel gear 322 meshing and drivingly connected with the transmission bevel gear 321 is fixedly installed on the mounting shaft 312; The transmission gear ring 37 is a toothed-ring with missing teeth, and it is in a tooth-missing state at the feeding position of the circulating conveying mechanism 2; When the conveying box 25 drives the kelp to move and be conveyed in the drying box 1 for drying, the conveying box 25 drives the transmission gear 36 to move along the transmission gear ring 37, so that the transmission gear 36 rotates under the meshing drive of the transmission gear ring 37. At the same time, the transmission gear 36 meshingly drives the driven gear 35 to rotate, so that the driven gear 35 drives the rotating shaft 34 to rotate. At this time, since the locking unit locks and fixes the rotating shaft 34 and the suspension rod 31, the suspension rod 31 rotates synchronously with the rotating shaft 34, and then the suspension rod 31 drives the hook 33 to rotate, so that the hook 33 drives the kelp suspended thereon to rotate, making the kelp heat more evenly and improving the drying effect of the kelp; When the kelp completes the drying process and moves one week with the hoisting mechanism 3 to reach the blanking position, the locking unit releases the locking between the rotating shaft 34 and the suspension rod 31 and locks and fixes the suspension rod 31 and the conveying box 25. At this time, the suspension rod 31 is locked and no longer rotates with the rotating shaft 34, so that when the rotating shaft 34 rotates, it can drive the mounting shaft 312 to rotate through the meshing drive between the transmission bevel gear 321 and the driven bevel gear 322, so that the mounting shaft 312 drives the hook 33 to flip and move, making the opening of the hook 33 face downward, and the kelp suspended thereon can slide off from the opening of the hook 33, thus completing the automatic unloading of the kelp. After that, the hook 33 moves to the feeding position. At this time, since the transmission gear ring 37 is in a tooth-missing state, the hook 33 is no longer limited by gear meshing, so that the staff can rotate the hook 33 back to its original position and hang new kelp on the hook 33 to continue the conveying and drying of the kelp.

[0029] Furthermore, the locking unit includes an upper friction disc 38, a lifting friction disc 39, a lower friction disc 310 and a guide rail 319. The upper friction disc 38 is fixedly installed at the upper end of the rotating shaft 34, the lower friction disc 310 is fixedly installed on the bottom wall inside the conveying box 25, the lifting friction disc 39 is slidably installed at the upper end of the suspension rod 31, and a spline 318 that slidably engages with the lifting friction disc 39 is arranged on the outer ring of the upper end of the suspension rod 31; A collar 316 is rotatably installed on the outer ring of the lifting friction disc 39, a lever frame 311 is rotatably installed on the outer ring of the collar 316, a support plate 317 is rotatably installed on the lever frame 311, the support plate 317 is fixedly installed inside the conveying box 25, one end of the lever frame 311 extends to the outside of the conveying box 25 and is fixedly installed with a guide block 320, the guide rail 319 is fixedly installed on the inner ring at the lower end of the track frame 26, and the guide block 320 is slidably engaged inside the guide rail 319; The guide rail 319 includes a drying limit guide rail and a discharging limit guide rail. The discharging limit guide rail is located at the loading and unloading position of the circulating conveying mechanism 2, and the height of the discharging limit guide rail is higher than that of the drying limit guide rail. At the same time, the discharging limit guide rail and the drying limit guide rail are connected by a guiding slope. When the kelp is moved and conveyed in the drying box 1 for drying, the guide block 320 is slidably engaged inside the drying limit guide rail, and at this time, the inner end of the lever frame 311 is inclined upward, so that the lever frame 311 drives the lifting friction disc 39 to move upward through the collar 316 and abut against the bottom surface of the upper friction disc 38. At this time, the suspension rod 31 and the rotating shaft 34 are locked by the frictional resistance between the upper friction disc 38 and the lifting friction disc 39, so that when the rotating shaft 34 rotates, it can drive the suspension rod 31 to rotate synchronously, so that the suspension rod 31 drives the hanging hook 33 and the kelp to rotate, improving the uniformity of heat reception of the kelp. When the suspension rod 31, the hanging hook 33 and the kelp move to the unloading position, the lever frame 311 drives the guide block 320 to move along the guiding slope into the discharging limit guide rail. At this time, the outer end of the lever frame 311 moves upward and the inner end moves downward, so that the inner end of the lever frame 311 drives the lifting friction disc 39 to move downward through the collar 316, so that the lifting friction disc 39 is separated from the upper friction disc 38, releasing the frictional lock between the suspension rod 31 and the rotating shaft 34. At the same time, the bottom surface of the lifting friction disc 39 abuts against the top surface of the lower friction disc 310 to lock and fix the suspension rod 31 to the conveying box 25 through the frictional resistance between the lifting friction disc 39 and the lower friction disc 310, preventing the suspension rod 31 from continuing to rotate with the rotating shaft 34, so that when the rotating shaft 34 rotates subsequently, it can drive the hanging hook 33 to turn over and unload the material; Through the cooperation of the upper friction disc 38, the lifting friction disc 39, the lower friction disc 310, the lever frame 311, the guide block 320 and the guide rail 319, the locking state between the suspension rod 31 and the rotating shaft 34 and between the rotating shaft 34 and the conveying box 25 can be automatically adjusted during the drying and unloading of the kelp, so that the hanging hook 33 can perform rotational or flipping movements, making the drying and unloading processes of the kelp more convenient and fast. Embodiment 6

[0030] Please refer to Figure 4 and Figure 6 As shown, the difference between this embodiment and the above-mentioned embodiment is that a reset hinge shaft 313 is rotatably installed on one side of the mounting frame 32. One end of the reset hinge shaft 313 is fixedly installed with a limit buckle 315 located at the opening of the lifting hook 33. A limit stop block 314 abuting against the upper side of the limit buckle 315 is also fixedly installed on the mounting frame 32; Among them, the limit buckle 315 is located at the opening of the lifting hook 33, which can limit and seal the opening of the lifting hook 33, prevent the kelp suspended on the lifting hook 33 from falling off the lifting hook 33, improve the stability of kelp suspension and transportation, and when suspending kelp, the limit buckle 315 can be pushed inward and rotated, so that the opening of the lifting hook 33 is exposed, making it more convenient to suspend kelp. After the kelp is suspended, when the pressure on the limit buckle 315 is released, the limit buckle 315 can rotate and reset under the action of the reset elastic force of the reset hinge shaft 313, and limit and seal the opening of the lifting hook 33 again.

Then, the circulating conveying mechanism 2 drives the lifting hook 33 and the kelp to move and be conveyed into the drying box 1, and gradually heat and dry the kelp through the heating components in the drying box 1; At the same time, the rotation driving component drives the suspension component and the lifting hook 33 to rotate synchronously, so that the lifting hook 33 drives the kelp to rotate synchronously during the moving and conveying process, making the kelp heat more evenly; Until the circulating conveying mechanism 2 drives the lifting hook 33 and the kelp to move and be conveyed in the drying box 1 for one week to complete the kelp drying process. Then, the lifting hook 33 and the kelp move to the discharging end of the circulating conveying mechanism 2. At this time, the rotation driving component drives the lifting hook 33 to flip and move at the bottom of the suspension component, so that the opening of the lifting hook 33 faces downward, enabling the kelp suspended on the lifting hook 33 to automatically slide off, realizing automatic discharging of the kelp; Then the lifting hook 33 moves to the feeding position again, and new kelp is suspended on the lifting hook 33 for drying.
