Abstract
Description
Technical Field
[0001] This invention relates to the field of screening equipment technology, specifically to a high-efficiency screening and automatic grading and crushing device for camellia fruit. Background Technology
[0002] Camellia oleifera fruit is the fruit of the Camellia oleifera plant, belonging to the genus Camellia in the family Theaceae. It is spherical or oval in shape. Camellia oleifera is an oil-bearing tree species unique to China. The tea oil extracted from its seeds contains over 90% unsaturated fatty acids and is also rich in vitamins E and D, making it highly nutritious. Furthermore, the fruit shell can be used to extract industrial raw materials such as uronic acid and xylitol, and can also be used to produce activated carbon and culture media for edible fungi.
[0003] After harvesting, camellia oleifera fruits need to be crushed before subsequent oil extraction. Existing camellia oleifera fruit crushing devices have a simple structure, generally consisting of a single crushing mechanism and a common screening device. In operation, the dried camellia oleifera fruits are directly poured into the machine for uniform crushing and then screened. Because the camellia oleifera fruits are of varying sizes, this type of machine easily leads to poor crushing efficiency and low productivity. Furthermore, multi-stage crushing can easily result in the outer shell of the camellia oleifera fruit being crushed too small, mixing with the fruit and causing difficulties in subsequent processing, as the outer shell also has significant uses and needs to be collected and processed.
[0004] Therefore, this application proposes a high-efficiency screening and automatic grading and crushing device for camellia fruit to solve the existing problems. Summary of the Invention
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a high-efficiency screening and automatic grading and crushing device for camellia fruit, which solves the problems of low efficiency in the current camellia fruit crushing and screening devices, and the tendency to crush the fruit shells too small, mixing them with the fruit and making subsequent processing inconvenient.

[0022] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example: like Figure 1-7 As shown, this embodiment of the invention provides a high-efficiency screening and automatic grading and crushing device for camellia fruit, including a main body 1. A shell-breaking box 2 is fixedly connected to one side of the top of the main body 1. A feeding channel 3 is fixedly connected to the upper end of the shell-breaking box 2. A support frame 4 is provided at the bottom of the main body 1. The bottom of the support frame 4 is integral, and the upper end has four support rods, which are respectively connected to the front and rear corners of the main body 1. A spring 16 is provided between the connection between the main body 1 and the support frame 4. A grading and crushing structure is provided inside the shell-breaking box 2 to grade and crush the camellia fruit. A screening structure is provided inside the main body 1 to separate and screen the fruit shells after crushing. A motor 18 is fixedly provided on one side of the support frame 4. The motor 18 drives the grading and crushing structure and the screening structure to work.
[0024] The grading and crushing structure includes a classification screen 7, a large crushing roller 8, a small crushing roller 10, and a partition plate 26. The classification screen 7 is fixedly installed at the inner end of the feed channel 3. The feed channel 3 is inclined and has an opening at its top. The top side of the classification screen 7 is located directly below the opening. When the camellia fruit enters the device, it can be screened into different crushing structures according to its size. Large crushing roller 8 and small crushing roller 10 are arranged parallel to each other inside the crushing box 2. The rear end of the large crushing roller 8 is rotatably connected to the inner wall of the crushing box 2 via a bearing, and the front end penetrates the front wall of the crushing box 2 and is connected to the large roller pulley 9. The rear end of the small crushing roller 10 is also rotatably connected to the inner wall of the crushing box 2 via a bearing, and the front end penetrates the front wall of the crushing box 2 and is connected to the small roller pulley 11. A first transmission belt 12 is connected between the large roller pulley 9 and the small roller pulley 11. A partition 26 is arranged between the large crushing roller 8 and the small crushing roller 10, and the front and rear sides of the partition 26 are fixedly connected to the front and rear inner walls of the crushing box 2. The lower end of the sorting screen 7 is located at the upper end of the partition 26. Large camellia fruits enter the large crushing roller 8 from the sorting screen 7, and small camellia fruits enter the small crushing roller 10 from the feeding channel 3 under the sorting screen 7.
[0025] Both the large crushing roller 8 and the small crushing roller 10 are equipped with several baffle rods 27 at their lower ends. The front and rear ends of the baffle rods 27 are connected to the front and rear walls of the crushing box 2, respectively. The baffle rods 27 are arranged in an arc shape, corresponding to the outer edge shape of the large crushing roller 8 and the small crushing roller 10. The spacing between the baffle rods 27 can be designed according to the required crushing fineness. The crushed product falls onto the upper separation screen 5 through the gap between the baffle rods 27.
[0026] The screening structure includes an upper separating screen 5, a lower separating screen 6, and a vibrating main shaft 14. The upper separating screen 5 and the lower separating screen 6 are arranged from top to bottom inside the main housing 1. Movable holes 28 are provided on both sides of the upper separating screen 5 and the lower separating screen 6. Limiting blocks 29 that cooperate with the movable holes 28 are provided on the inner wall of the main housing 1. The upper separating screen 5 and the lower separating screen 6 achieve short-stroke vertical movement through the cooperation of the movable holes 28 and the limiting blocks 29. The front wall of the main housing 1... A bearing housing 13 with a vertical support is fixedly installed at the center. The rear end of the vibrating main shaft 14 is rotatably connected to the bearing housing 13 with a vertical support. A main shaft pulley 15 is fixedly connected to the front end of the vibrating main shaft 14. An eccentric block 17 is fixedly sleeved on the shaft body near the front end of the vibrating main shaft 14. A third transmission belt 21 is connected between the main shaft pulley 15 and the small drum pulley 11. A motor pulley 19 is fixedly connected to the output end of the motor 18. A second transmission belt 20 is connected between the motor pulley 19 and the main shaft pulley 15.
[0027] When the motor 18 is working, it drives the vibrating main shaft 14 to rotate through the second transmission belt 20. When the vibrating main shaft 14 rotates, it drives the main housing 1 to vibrate. At this time, the upper separation screen 5 and the lower separation screen 6 inside it will bounce up and down to perform screening. When the vibrating main shaft 14 rotates, it drives the small drum pulley 11 to rotate through the third transmission belt 21, and then drives the large drum pulley 9 to rotate through the first transmission belt 12, thereby driving the large shell-breaking drum 8 and the small shell-breaking drum 10 to rotate.
[0028] The main box 1 is open at the end away from the shell breaking box 2. The upper separation screen 5 and the lower separation screen 6 both pass through the opening of the main box 1 on the same side. The main box 1 is tilted towards the opening end.
[0029] The inner end of the main box 1 is also provided with a stop plate 22, which is located directly above the upper separation screen 5. The front and rear walls of the main box 1 are both fixedly provided with slide rails 23 near the upper side. Sliding sliders 24 are slidably provided in the two slide rails 23. The front and rear sides of the stop plate 22 are respectively fixedly connected to the two sliding sliders 24. The outer sides of the two sliding sliders 24 are fixedly connected with handles 25. The upper end of the stop plate 22 is a flat plate, and several round rods are fixedly connected to the bottom end of the flat plate. The position of the round rods on the stop plate 22 corresponds vertically to the screen holes on the upper separation screen 5. When the screen holes on the upper separation screen 5 are blocked, the round rods on the plate will pass through the screen holes and discharge the blockage by pressing down the stop plate 22 with the handles 25.
[0030] Both the small roller pulley 11 and the main shaft pulley 15 are double-channel pulleys, which can be connected to two belts.
[0031] Working principle: When in use, start the motor 18 and pour the camellia fruit into the device through the opening on the feed channel 3. After being screened by the sorting screen 7 according to size, the camellia fruit is then processed by the large shell-breaking roller 8 and the small shell-breaking roller 10. The shelled product falls onto the upper separation screen 5 through the gap of the baffle rod 27. After being processed by vibrating screen, the small particles fall onto the lower separation screen 6. After being vibrating screen again, the camellia fruit falls to the bottom of the main box 1 and is discharged from the main box 1 through the outlet. The camellia fruit shells on the upper separation screen 5 and the lower separation screen 6 are also discharged from the outlet.
[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
