TECHNICAL FIELD
[0001] The present application relates to the technical field of jujube drying, in particular to a rotary jujube rapid drying device. BACKGROUND
[0002] Fresh jujubes are dried to obtain dried jujubes. Dried jujubes are easy to digest and convenient to store. The dried jujubes for storage are required to be moderately dried, not damaged, free of pests and diseases, have a red color, and be uniform in size. Since dried jujubes have the effects of nourishing yin and yang and tonifying blood, dried jujubes are increasingly favored by people. However, fresh jujubes have a short shelf life, and jujubes need to be cleaned during processing. Therefore, in order to store and transport jujubes for a long time, jujubes need to be dried, and a drying device is needed.
[0003] The existing jujube drying technology is searched, and the currently published jujube drying technology is to arrange the cleaned jujubes in multiple layers and place them in the box body for drying. For example, the utility model patent with the publication number CN216204782U discloses a drying device for fresh jujube processing. The space utilization rate in the box body is improved by arranging the jujubes in multiple layers, and the drying effect is enhanced. However, the hot air generated during drying is difficult to escape due to the multiple layers, and the jujubes are difficult to move on the placement plate, which may cause incomplete drying. Therefore, the published patent technology is searched, such as the invention patent with the publication number CN116548502B, which discloses a drying device for jujube processing. The jujubes are driven to move by a driving assembly to improve the drying effect. However, the capacity space of the drying box body is occupied by the structure such as the spoiler, which affects the amount of jujubes dried and reduces the drying efficiency.
[0004] In view of the problems of the existing jujube drying device, a rotary jujube rapid drying device is provided. SUMMARY

Detailed Implementation
[0081] 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.
[0082] Example 1, please refer to Figures 1 to 12 A rotary jujube rapid drying device includes a housing 1 and a rotating drum 2 rotatably disposed inside the housing 1. Drive shafts 3 are coaxially disposed at both ends of the rotating drum 2. The device also includes a drive assembly, a linkage assembly, a circumferential drying assembly, and an opening and closing assembly. The drive assembly is disposed inside the housing 1 and is used to drive the rotating drum 2 to rotate. The linkage assembly has a slow-motion function and is disposed between the rotating drum 2 and the drive assembly. The circumferential drying assembly is coaxially disposed on the outside of the rotating drum 2 and is used to uniformly dry the jujubes inside the rotating drum 2. The opening and closing assembly is disposed on the housing 1 and is used to control the opening and closing of the rotating drum 2 to facilitate the feeding and discharging of jujubes.
[0083] The opening and closing of the rotating drum 2 can be controlled by the opening and closing component. When the rotating drum 2 is open, it facilitates the conveying of red dates to be dried into the drum and also facilitates the conveying of dried red dates to the outside. When the rotating drum 2 is closed, it facilitates the rotation of the rotating drum 2 to cooperate with the circumferential drying component to fully dry the red dates inside. The drive component can drive the rotating drum 2 to rotate, and the rotation of the rotating drum 2 can make the red dates inside the rotating drum 2 tumble continuously, improving the drying effect. The linkage component can make the drum rotate while also continuously moving and shaking, improving the tumbling effect of the red dates inside the rotating drum 2, so that the drying component can better dry the red dates from all directions. The circumferential drying component can perform circumferential drying of the rotating drum 2, enhancing the drying efficiency. Compared with the existing technology, it can improve the tumbling effect of the red dates, increase the area of the red dates to be dried, and at the same time, it does not occupy the internal space of the rotating drum 2, increasing the amount of red dates dried and improving the drying efficiency.
[0084] Furthermore, a feed inlet is provided on the top of the box body 1, and a support 4 is provided at the bottom of the box body 1. A discharge port is provided on the front side of the box body 1. A feed hopper 5, an alignment frame 6, and a telescopic sleeve 7 are provided on the feed inlet. The feed hopper 5 is connected to the feed inlet. The alignment frame 6 is located directly below the feed inlet. The telescopic sleeve 7 is connected between the feed hopper 5 and the alignment frame 6.
[0085] The bracket 4 provides stable support for the box 1. The feeding hopper 5, alignment frame 6, and telescopic sleeve 7 work together to facilitate the conveying of the dates to be dried into the rotating drum 2, where the dates are tumbled and dried. The dried dates can be conveyed to the next processing step through the discharge port. The discharge port is inclined with a conveyor hopper, which is located below the rotating drum to facilitate the outward conveying of the dried dates. In order to facilitate the conveying of dates from low to high into the feeding hopper 5, a conveyor 8 is provided on one side of the box 1. The conveyor 8 facilitates the conveying of dates at lower positions into the feeding hopper 5. The conveyor 8 is a known existing device, and its operating principle will not be described in this embodiment.
[0086] Based on the aforementioned scheme, the drive assembly includes a support plate 9, a motor 10, and a drive sleeve 11. There are two support plates 9, which are symmetrically arranged on both sides of the rotating drum 2. Motors 10 are installed on both sides of the housing 1, and the output shaft of the motor 10 passes through the housing 1 and the support plate 9. The output shaft of the motor 10 is coaxially connected to the drive sleeve 11.
[0087] The rotating drum 2 can be supported by the support plate 9, and the drive sleeve 11 can be rotated by the motor 10. The drive sleeve 11 is used to connect with the rotating drum 2, so that the rotation of the motor 10 drives the drive sleeve 11 to rotate, thereby driving the rotating drum 2 to rotate.
[0088] Furthermore, the linkage assembly includes a connecting spring 12, a stabilizing rod 13, a stabilizing ball 14, and a spherical cavity 15. The drive shaft 3 extends into the drive sleeve 11, and the outer wall of the drive shaft 3 is connected to the inner wall of the drive sleeve 11 by a plurality of circumferentially arranged connecting springs 12. The stabilizing rod 13 is coaxially connected inside the drive sleeve 11, and the other end of the stabilizing rod 13 is connected to the stabilizing ball 14. The drive shaft 3 has a spherical cavity 15 inside, and the outer end of the spherical cavity 15 communicates with the outside. The stabilizing ball 14 is disposed inside the spherical cavity 15, and the space of the spherical cavity 15 is larger than that of the stabilizing ball 14.
[0089] The connecting springs 12 arranged circumferentially connect the drive sleeve 11 and the rotating drum 2. When the motor 10 rotates, it drives the rotating drum 2 to rotate. Because the dates continuously tumble inside the rotating drum 2, the force on the drum 2 is uneven, causing the connecting springs 12 to compress or stretch. This results in continuous vibration during rotation, further enhancing the tumbling effect of the dates inside the drum 2. It should be noted that the rotating drum 2 rotates slowly, not at high speed. Furthermore, the connecting springs 12 are evenly arranged circumferentially between the drive shaft 3 and the drive sleeve 11 (preferably an even number of connecting springs 12 between the drive shaft 3 and the drive sleeve 11). When the rotation is uniform, the rotating drum 2 and the drive sleeve 11 are coaxial. When the jujubes roll continuously, the rotating drum 2 is subjected to uneven force. One side of the connecting spring 12 on the drive shaft 3 is compressed or stretched, and the corresponding spring on the other side is stretched or compressed. This ensures that the drive sleeve 11 can drive the rotation of the rotating drum 2 while also enhancing the vibration of the rotating drum 2. Through the cooperation between the spherical cavity 15 and the stabilizing ball 14, where the inner size of the spherical cavity 15 is much larger than the size of the stabilizing ball 14, but the outer diameter of the stabilizing ball 14 is larger than the inner diameter of the opening of the spherical cavity 15 that connects to the outside, the vibration effect of the rotating drum 2 is ensured. At the same time, it can also prevent the rotating drum 2 from detaching from the drive sleeve 11 and improve the stability of the rotating drum 2 in use.
[0090] Furthermore, the circumferential drying assembly includes a large gear disc 16, a dryer, a small gear disc 17, a small gear disc 28, a small gear 19, and a small gear 20, all coaxially mounted on the output shaft of the motor 10. The large gear disc 16 is rotatably connected to the output shaft of the motor 10. The dryer is coaxially mounted on the outside of the rotating drum 2 and connected between the two large gear discs 16. The small gear disc 17 is coaxially mounted on the output shaft of the motor 10 and is fixedly connected to the output shaft of the motor 10. The small gear disc 28 is rotatably mounted on the support plate 9, and the small gear disc 17 meshes with the small gear disc 28. The small gear 19 is rotatably mounted on the support plate 9 via a rotating shaft and meshes with the small gear disc 28. The small gear 20 is coaxially and fixedly connected to the rotating shaft and meshes with the large gear disc 16.
[0091] The rotation of motor 10 drives the small gear disc 17 to rotate, which in turn drives the small gear disc 18 to rotate, which in turn drives the small gear 19 to rotate. Through the meshing between the small gear 19 and the small gear 20, the rotation of motor 10 causes the small gear 20 to rotate. Since the small gear 20 meshes with the large gear disc 16, it drives the large gear disc 16 to rotate slowly. The slow rotation of the large gear disc 16 can drive the dryer to rotate slowly outside the rotating drum 2, thereby effectively and evenly drying the red dates inside the rotating drum 2, improving the drying effect, and further enhancing the dryer's effect of thoroughly drying the red dates.
[0092] Based on the aforementioned scheme, the dryer includes a frame 21, a heating chamber 22, heating rods 23, and a fan 24. At least two frames 21 are provided, and the two frames 21 are arranged symmetrically. The two ends of each frame 21 are connected to the inner walls of two large gear discs 16 respectively. The heating chamber 22 is provided inside the frame 21, and an air outlet is provided on the side of the heating chamber 22 near the rotating drum 2. Multiple heating rods 23 are arranged inside the heating chamber 22 along the length of the heating chamber 22. Multiple fans 24 are installed on the outer wall of each frame 21, and the air outlet of the fan 24 communicates with the inside of the heating chamber 22.
[0093] The fan 24 generates airflow that blows into the heating chamber 22. The heating rod 23 heats the air inside the heating chamber 22, generating hot air from the outlet and blowing it onto the dates inside the rotating drum 2. The multiple fans 24 ensure more comprehensive drying. The symmetrical arrangement of at least two frames 21 further enhances the drying effect. The number of frames 21 can be adjusted according to actual drying needs. The power cables for the fans 24 and heating rods 23 are connected via a conductive slip ring 50. The conductive slip ring 50 is coaxially mounted on the outside of the output shaft of the motor 10 and coaxially connected to the large gear disc 16. This ensures that the fans 24 and heating rods maintain electrical continuity while rotating with the large gear disc 16, improving reliability.
[0094] Furthermore, the rotating drum 2 includes a circular plate 25, connecting rods 26, arc-shaped grooves, and pull wires 27. The circular plates 25 are arranged on both sides of the rotating drum 2, and the drive shaft 3 is coaxially connected to the circular plates 25. Multiple connecting rods 26 are equidistantly arranged on the circumference between the two circular plates 25. The connecting rods 26 are cylindrical. Two arc-shaped grooves are provided on the opposite side wall of each of the two circular plates 25. The two arc-shaped grooves on each circular plate 25 are symmetrically arranged, and the arc-shaped grooves are consistent with the curvature of the circular plate 25. The two ends of the connecting rods 26 are slidably arranged in the arc-shaped grooves located on both sides of them, and the multiple connecting rods 26 located in the arc-shaped grooves on the same side are equidistantly connected by pull wires 27.
[0095] The pull line 27 ensures the integrity of the multiple connecting rods 26 and ensures that the distance between the connecting rods 26 is equal. The arc-shaped slide groove allows the multiple connecting rods 26 located inside the arc-shaped slide groove to slide and squeeze together, thereby forming an opening at the top of the rotating drum 2, which facilitates the delivery of red dates into the rotating drum 2 and also facilitates the discharge of red dates outward.
[0096] Preferably, the opening and closing assembly includes a first turntable 28, a second turntable 29, a first driving rod 30, a second driving rod 31, a drive groove, a reset structure, and an ejection mechanism. The first turntable 28 is coaxially and rotatably mounted on the outer wall of the turntable. The second turntable 29 is coaxially and rotatably mounted on the outer wall of the first turntable 28. The first driving rod 30 is connected to the first turntable 28, and its other end is vertically connected to a first lever 32. The second driving rod 31 is connected to the second turntable 29, and its other end is vertically connected to a lever. Shaft 2 33, the drive groove is set on the outer wall of the circular plate 25, and the curvature of the drive groove is consistent with that of the arc-shaped slide groove. The width of the drive groove is smaller than the width of the arc-shaped slide groove. Shaft 1 32 and Shaft 2 33 are respectively located in the corresponding drive grooves, and Shaft 1 32 and Shaft 2 33 are respectively coaxially connected to the connecting rod 26 at the corresponding position. Turntable 1 28 and Turntable 2 29 are both provided with a reset structure between them and the circular plate 25. The ejection mechanism is set above and below the housing 1 to drive Turntable 1 28 and Turntable 2 29 to rotate.
[0097] The ejection mechanism can drive turntable 28 and turntable 29 to rotate in opposite directions simultaneously, thereby causing pivot 32 and pivot 33 to rotate in opposite directions simultaneously. This, in turn, pushes multiple connecting rods 26 inside the corresponding arc-shaped groove to squeeze together along the arc-shaped groove, thus forming an opening on the rotating drum 2. When it is necessary to close the rotating drum 2, the ejection mechanism retracts. At this time, under the action of the reset structure, turntable 28 and turntable 29 drive the connecting rods 26 to return to their original state (the distance between the connecting rods 26 in the original state is smaller than the size of the jujube), ensuring that the jujube does not leak out.
[0098] More preferably, the reset structure includes a fixed plate 34, a movable plate 35, an arc-shaped rod 36, a reset spring 37, and a locking mechanism. The fixed plate 34 is fixedly connected to the outer wall of the circular plate 25. Movable plates 35 are connected to the outer walls of both turntable 1 28 and turntable 29. The arc-shaped rod 36 slides through the fixed plate 34 and is connected to the movable plate 35. The reset spring 37 is fitted on the outside of the arc-shaped rod 36, and both ends of the reset spring 37 abut against the fixed plate 34 and the movable plate 35, respectively. The locking mechanism is set on the circular plate 25 and is used to lock the connecting rod 26 after it is closed.
[0099] When turntable 28 and turntable 29 are pushed by the ejection mechanism, they rotate. At this time, the return spring 37 is compressed and generates elastic force. When the ejection mechanism retracts, the elastic force on the return spring 37 pushes turntable 28 and turntable 29 to rotate in the opposite direction to their original positions and locks them through the locking mechanism. The locking mechanism prevents the connecting rod 26 from shaking and increasing the distance between the connecting rods 26 when the drum 2 rotates, thus ensuring that the jujubes are effectively dried inside the drum 2.
[0100] Furthermore, the ejection mechanism includes an electric cylinder 38, a U-shaped frame 39, an electric cylinder 40, a U-shaped frame 41, a push rod 42, and a drive frame 43. Two electric cylinders 38 are symmetrically installed on the top side wall of the housing 1 about the feed hopper 5. The bottom output end of each electric cylinder 38 is connected to a U-shaped frame 39. Two electric cylinders 40 are symmetrically installed on the bottom side wall of the housing 1, and the electric cylinders 40 are longitudinally aligned with the electric cylinders 38. The top output end of each electric cylinder 40 is connected to a U-shaped frame 41. A push rod 42 is connected to the outer wall of the turntable 28 and the turntable 29. The drive frame 43 is fixedly installed on the outside of the alignment frame 6, and the two ends of the drive frame 43 are fixedly connected to the two U-shaped frames 39 respectively.
[0101] When red dates need to be added to the rotating drum 2, the "opening" of the rotating drum 2 faces upward. By controlling the two electric cylinders 38 to operate simultaneously (connected to the same control switch), the electric cylinders 38 push the U-shaped frame 39 downward. The bottom end of the U-shaped frame 39 contacts the push rods 42 on the first and second turntables 28 and 29, pushing the first and second turntables 28 and 29 to rotate in opposite directions. This causes the dial shaft 32 and the dial plate 2 to rotate the connecting rods 26 on both sides, forming an opening at the top of the rotating drum 2. Since the drive frame 43 is connected to the alignment frame 6, when the U-shaped frame 39 moves downward, the drive frame 43 also drives the alignment frame 6. The cylinder moves downwards and closer to the top of the rotating drum 2. Therefore, when the top of the rotating drum 2 forms an opening, the jujubes can be effectively conveyed into the rotating drum 2 through the feed hopper 5, telescopic sleeve 7, and alignment frame 6. When the electric cylinder 38 retracts, the connecting rod 26 on the rotating drum 2 resets, and the alignment frame 6 also returns to its original position, preventing the alignment frame 6 from affecting the rotation of the rotating drum 2. Similarly, when it is necessary to discharge the dried jujubes, the "opening" position of the rotating drum 2 is rotated downwards. The extension of the electric cylinder 40 drives the U-shaped frame 41 to move upwards, causing the turntables 28 and 29 to rotate, allowing the jujubes to fall downwards. The falling jujubes fall into the conveyor belt. The jujubes are fed into the hopper and discharged to the next processing step. It should be noted that regarding the positioning of the rotating drum 2 to mate with either U-shaped frame 39 or U-shaped frame 41, in the first embodiment, a position sensor can be used to identify the position. An identification mark is set on the circular plate 25 at the "opening" of the rotating drum 2, and the position is controlled by the position sensor. In the second embodiment, an electromagnet can be installed in the middle of either U-shaped frame 39 or U-shaped frame 41, and a magnet that attracts the electromagnet is correspondingly placed on the circular plate 25 at the "opening" of the rotating drum 2. The position is then controlled by... The motor 10 rotates slowly, bringing the magnet on the circular plate 25 close to the electromagnet. The motor 10 is then turned off (the motor 10 is a motor without a brake function, and the output shaft of the motor 10 can still rotate freely after it is turned off). At this time, the electromagnet attracts the magnet on the circular plate 25 through attraction. The magnet and the electromagnet are closest, and the attraction is the greatest, which further improves the alignment of the alignment frame 6 and the "opening" on the rotating drum 2. In the third implementation, an observation panel is provided on the side wall of the housing 1, which can also be used for manual observation. By controlling the slow rotation of the motor 10, the rotating drum 2 can be manually adjusted to the required position (a conspicuous mark needs to be made on the circular plate 25).
[0102] To further explain, the alignment frame 6 moves downwards towards the rotating drum 2 without contacting the connecting rod 26 on the rotating drum 2. This ensures that the connecting rod 26 can be moved by the action of the first rotating disc 28 and the second rotating disc 29. The distance between the alignment frame 6 and the connecting rod 26 is smaller than the size of the jujube. In addition, the width of the alignment frame 6 is smaller than the width of the "opening" formed on the rotating drum 2. This avoids errors caused by the rotating drum 2's inaccurate positioning, ensuring that all the jujubes inside the feed hopper 5 can be conveyed into the rotating drum 2. Furthermore, the push rod 42 has a certain length, ensuring that the first U-shaped frame 39 or the second U-shaped frame 41 can continue to effectively push the slightly tilted first rotating disc 28 or the second rotating disc 29.
[0103] Example 2, this example is based on Example 1, please refer to... Figure 8 and Figure 10 The locking mechanism includes a locking block 44. Each circular plate 25 has two adjacent drive slots with locking cavities, which are connected to the drive slots via locking holes. A locking block 44 is slidably mounted inside the locking holes. A limit plate 45 is also connected to the locking block 44, located inside the locking cavity. The limit plate 45 is connected to the locking cavity via a spring 46. Both the first and second pivot shafts 32 and 33 have insertion holes adapted to the locking block 44. The two locking mechanisms... A connecting groove is provided between the fixed cavities, and a connecting plate 47 is provided in the connecting groove. The connecting plate 47 is connected to the limiting plate 45 inside the two locking cavities. The middle part of the connecting groove extends outward from the circular plate 25 and communicates with the outside. An operating rod 48 is connected to the middle part of the connecting plate 47. The operating rod 48 extends to the outside of the circular plate 25. The bottom ends of the connecting plate 47 and the operating rod 48 are connected to the connecting groove with a retaining spring 46. A touch rod 49 is connected to the middle of the U-shaped frame 39 and the U-shaped frame 41.
[0104] When the "opening" on the rotating drum 2 is closed, both the first pivot 32 and the second pivot 33 return to their original positions. At this time, the first pivot 32 and the second pivot 33 push the corresponding locking blocks 44 into the locking cavity. The locking blocks 44 have inclined surfaces on the side near the first pivot 32 or the second pivot 33 to facilitate the first pivot 32 and the second pivot 33 pushing the locking blocks 44. When the locking blocks 44 are aligned longitudinally with the insertion hole, under the action of the retaining spring 46, the locking blocks 44 can be inserted into the insertion hole, thereby ensuring that the first pivot 32 and the second pivot 33 no longer slide, improving the stability of the rotating drum 2 during use. When it is necessary to open the "opening" on the rotating drum 2, the touch rod 49 is set so that when the U-shaped frame 39 or the second U-shaped frame 41 approaches the rotating drum 2, the touch rod 49 will first touch the opening. Operating lever 48 drives limiting plate 45 to slide inside locking cavity. At this time, clamping spring 46 is compressed, and locking block 44 is pulled out inside insertion hole. The depth of connecting groove or locking cavity is greater than the depth of locking block 44 inserted into insertion hole. After locking block 44 is pulled out inside insertion hole, dial shaft 1 32 and dial shaft 2 33 are released. At the same time, U-shaped frame 1 39 or U-shaped frame 2 41 contacts push rod 42. Operating lever 48 and push rod 42 continue to be pressed simultaneously, thereby opening the "opening" on rotating drum 2. When the "opening" is closed, U-shaped frame 1 39 or U-shaped frame 2 41 returns to its original position. Locking block 44 and rotating disk 1 28 or rotating disk 2 29 return to their original positions under the action of clamping spring 46 and return spring 37, respectively, so that rotating drum 2 can be used effectively.
[0105] In summary, when using this rotary jujube rapid drying device, firstly, the "opening" position of the rotating drum 2 is aligned upwards with the U-shaped frame 39. Then, the electric cylinder 38 is activated, controlling both electric cylinders 38 to move downwards simultaneously. This causes the alignment frame 6 to move downwards, opening the top of the rotating drum 2 to form an "opening." The washed jujubes are then conveyed into the conveyor 8, which transports the jujubes to be dried to the top of the feed hopper 5 and into the rotating drum 2. Once the required drying capacity is reached inside the rotating drum 2, the conveyor 8 controls the electric cylinder 38 to move upwards, causing the turntables 28 and 29 to rotate back to their original positions. This closes the "opening" on the rotating drum 2 and locks it with the locking mechanism. Then, the motor 10, heating rod 23, and fan 24 are powered on. When the motor 10 rotates, it drives the rotating drum 2 to rotate slowly. The jujubes are continuously tumbling and shaking inside the rotating drum 2. Simultaneously, the dryer rotates around the drum 2 to provide all-around hot air drying. After drying, the "opening" of the drum 2 is rotated to a position where its lower side aligns longitudinally with the U-shaped frame 41. Two electric cylinders 40 are simultaneously controlled to open the "opening" of the drum 2, allowing the dried jujubes to be conveyed to the next processing step via a conveyor hopper. Additionally, symmetrical air inlets and outlets are provided on the side walls of the chamber 1, each equipped with filter cotton and an inlet fan 24 and an outlet fan 24, respectively. This ensures the flow of clean air inside the chamber 1 and the removal of hot air generated during drying, improving the drying effect. It should be noted that the jujube processing workshop itself has a purification level treatment to ensure food safety.
