Description

Technical Field

[0001] This invention relates to the field of drying and feeding technology, and in particular to a graded feeding device for multi-layer drying racks. Background Technology

[0002] Camellia oil, also known as wild camellia oil, tea seed oil, or oil tea seed oil, is extracted from the seeds of the camellia tree (Camellia oleifera), a plant belonging to the Theaceae family. Its manufacturing process can be divided into: shelling, drying, crushing, steaming, pressing, and filtering.

[0003] Sun-drying camellia seeds is a crucial step in camellia oil processing, directly impacting oil yield and quality. Traditional flat-laying sun-drying is limited by space, resulting in low efficiency, susceptibility to mold, and the need for frequent manual turning. With the large-scale development of the camellia oil industry, the advantages of multi-layered drying racks have become increasingly apparent. They improve space utilization, allow for multi-directional ventilation, and are essential tools for enhancing sun-drying effectiveness, ensuring efficiency, and maintaining the flavor of the camellia oil.

[0004] A search revealed that Chinese invention patent CN112623616B discloses a multi-layer three-dimensional Polygonatum sibiricum drying system, including a three-dimensional drying rack, a feeding system, a discharging system, and a control system. The three-dimensional drying rack has multiple drying beds arranged in a stepped layout. At the feeding end of the three-dimensional drying rack, the feeding end of the lower drying bed extends beyond the feeding end of the upper drying bed, forming a positive stepped shape. At the discharging end of the drying bed, the feeding end of the lower drying bed is recessed within the feeding end of the upper drying bed, forming a reverse stepped shape. The feeding system includes a feeding conveyor with an adjustable feeding position. The discharging system consists of a material baffle located at the discharging end of the drying bed, with a material conveyor located at the bottom of the material baffle. The application uses a mobile feeding conveyor to feed materials onto a stepped, multi-layered drying bed to provide a batch and continuous supply of materials. However, this method cannot guarantee that each drying bed can be fed with an equal amount of material. As a result, the drying environment of materials in different layers will be different, which will lead to uneven drying rates of each layer and affect the overall drying efficiency and drying effect. Summary of the Invention

[0005] In view of the above-mentioned prior art, the present invention provides a graded feeding device for multi-layer drying racks, and the main technical problem to be solved is how to uniformly feed materials to multi-layer drying racks.

[0006] To achieve the above objectives, the technical solution of this invention is implemented as follows: A grading and feeding device for a multi-layer drying rack includes an outer box, within which a drive mechanism and a guiding mechanism are provided. The drive mechanism includes a motion component and a crank assembly. The guiding mechanism includes a material cylinder for receiving and conveying materials and several shelves at different heights. The motion component intermittently drives the material cylinder to move up and down and reciprocate to distribute materials to each shelf. One end of each shelf is provided with a guide plate, and the crank assembly pushes materials into the multi-layer drying rack by driving the guide plate to swing.

[0007] Furthermore, several shelves are fixedly connected at equal intervals from top to bottom at the front end of the outer box. The shelves are in an inclined state, and guide plates are rotatably connected to the front side of the shelves. Several guide plates are rotatably connected to the same side plate on one side.

[0008] Furthermore, a motor is fixedly connected to the bottom of the outer casing, and a connecting shaft is fixedly connected to one end of the motor's output shaft. The same housing is fixedly connected to the bottom of the outer casing outside the motor and the connecting shaft.

[0009] Furthermore, the crank assembly includes a connecting rod and a turntable. One end of the connecting rod rotates with the bottom end of the side plate, and the other end of the connecting rod is rotatably connected to one side edge of the turntable. The turntable is connected to one end of the connecting shaft by a key.

[0010] Furthermore, a rotating shaft is provided through the bottom of the outer casing on the inner side of the housing. The top of the rotating shaft is connected to a drive roller via a key. A driven roller is rotatably connected to one side of the inner wall at the bottom of the outer casing. The drive roller and the driven roller are fitted with the same belt.

[0011] Furthermore, a partition is fixedly connected to the bottom of the inner casing, and the motion components include a reciprocating screw that passes through one side of the partition, a gear connected to the outside of the reciprocating screw by a key, and racks fixed to the outside of the belt at equal intervals.

[0012] Furthermore, the rack meshes with the gear, and bevel gears are connected to the outside of the connecting shaft and the bottom of the rotating shaft via keys, with the two bevel gears meshing.

[0013] Furthermore, the reciprocating screw is externally threaded with a nut, and a slide rod is fixedly connected to the top of the partition plate on the side away from the reciprocating screw. A sliding sleeve is fitted around the slide rod, and the barrel is fixedly connected between the nut and the sliding sleeve.

[0014] Furthermore, a feed hopper is provided through the top of the outer casing, and a telescopic sleeve is fixedly connected between the feed hopper and the material cylinder.

[0015] Furthermore, an electric baffle gate is fixedly connected inside the feed hopper.

[0016] The beneficial effects of this invention are as follows: 1. This application utilizes the intermittent lifting and lowering movement of the material cylinder to allow it to stop at different shelves during the lifting and lowering process, so as to transfer the material put into the outer box to the shelves of different levels. At the same time, in conjunction with the continuous oscillation of the guide plate, the material can be pushed into the multi-layer drying rack to complete the graded feeding. Through the regular reciprocating movement and intermittent stopping of the material cylinder, the material can be evenly distributed to the shelves of different heights to maintain the consistency of the environment of the material in each level, thereby ensuring drying efficiency and drying effect. 2. The telescopic sleeve, through its own stretchable and deformable characteristics, can adapt to the lifting and reciprocating movement of the material cylinder. The telescopic sleeve can also receive materials from the feed hopper and accurately transfer them into the material cylinder to avoid material leakage and waste, or affect the smooth transmission of internal parts of the device. 3. By installing an electric baffle door in the feeding hopper, when the previous drying rack is full of material, the feeding hopper can be paused by closing the electric baffle door. At this time, there will be no material leakage when changing the drying rack. Afterwards, you can continue feeding by simply reopening the electric baffle door. Attached Figure Description

[0019] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0020] Example 1 See attached document Figure 1-4 This application provides a grading and feeding device for a multi-layer drying rack, including an outer box 1. The outer box 1 is provided with a drive mechanism and a guiding mechanism. The drive mechanism includes a motion component and a crank component. The guiding mechanism includes a material cylinder 22 for receiving and transmitting materials and several shelves 3 at different heights. The shelves 3 are used to transport materials to different height levels of the multi-layer drying rack. The motion component distributes materials to each shelf 3 by intermittently driving the material cylinder 22 to move up and down and back and forth. The regular movement of the material cylinder 22 can ensure the uniformity of material distribution, thereby ensuring that the amount of material at different levels is equal. This device is located between the feeding machine and the multi-layer drying rack, and mainly serves to grade and feed materials. The feeding machine can be a conveyor belt type or a suction type. Since the feeding machine and the multi-layer drying rack are very common in this field, they are not shown in the figure and are not described in detail.

[0021] Preferably, the shelf 3 is in an inclined state, and a guide plate 4 is provided at one end of the shelf 3. The crank assembly drives the guide plate 4 to swing and push the material into the multi-layer drying rack. The inclined shelf 3 can make the material roll on its surface under its own weight. Therefore, in conjunction with the swinging guide plate 4, the material falling into the drying rack can be prevented from piling up. Instead, it will be dispersed by the push of the guide plate 4, which is conducive to drying.

[0022] Preferably, several shelves 3 are fixedly connected at equal intervals from top to bottom at the front end of the outer box 1. A guide plate 4 is rotatably connected to the front side of the shelf 3 and extends to the outside of the outer box 1. Therefore, when the drying rack is placed at the front end of the outer box 1, the guide plate 4 can extend into the drying rack to ensure stable and smooth feeding and prevent material leakage between the two. The same side plate 5 is rotatably connected to one side of several guide plates 4.

[0023] Preferably, a motor 15 is fixedly connected to the bottom of the outer casing 1, and a connecting shaft 18 is fixedly connected to one end of the output shaft of the motor 15. The same housing 14 is fixedly connected to the bottom of the outer casing 1 outside the motor 15 and the connecting shaft 18. The connecting shaft 18 is disposed through one side of the housing 14 and is rotatably connected to it.

[0024] Preferably, the crank assembly includes a connecting rod 6 and a turntable 7. One end of the connecting rod 6 rotates with the bottom end of the side plate 5, and the other end of the connecting rod 6 is rotatably connected to one side edge of the turntable 7. Therefore, the rotation of the turntable 7 can cause the connecting rod 6 to change position, thereby driving the side plate 5 to swing the guide plate 4. The turntable 7 is connected to one end of the connecting shaft 18 by a key.

[0025] Preferably, a rotating shaft 17 is provided through the bottom end of the outer casing 1 inside the housing 14. The rotating shaft 17 is rotatably connected to the outer casing 1. The top end of the rotating shaft 17 is connected to a drive roller 20 via a key. A driven roller 11 is rotatably connected to one side of the bottom inner wall of the outer casing 1. The drive roller 20 and the driven roller 11 are fitted with the same belt 12.

[0026] Preferably, a partition 13 is fixedly connected to the bottom of the inner part of the outer casing 1. The moving component includes a reciprocating screw 9 that passes through one side of the partition 13, a gear 10 connected to the outside of the reciprocating screw 9 by a key, and racks 19 that are fixed at equal intervals to the outside of the belt 12. The reciprocating screw 9 is rotatably connected to the partition 13. The racks 19 are evenly spaced outside the belt 12, so the continuous movement of the belt 12 will intermittently drive the gear 10 to rotate, thereby causing the lifting and lowering movement of the screw nut 8 to stop intermittently.

[0027] Preferably, the rack 19 meshes with the gear 10. The rack 19 is a flexible rack, which consists of a base made of flexible material and tooth blocks equidistantly arranged on the base. The tooth blocks are adapted to the gear 10. The base can adapt to the arc surface of the driving roller 20 and the driven roller 11 by changing its own shape. When the rack 19 meshes with the gear 10, the driven roller 11 can provide support for the rack 19 to ensure a full meshing effect with the gear 10. The outside of the rod of the connecting shaft 18 and the bottom of the rotating shaft 17 are connected to bevel gears 16 by keys. The two bevel gears 16 mesh.

[0028] Preferably, the reciprocating screw 9 is externally threaded with a nut 8, and the top of the partition plate 13 is fixedly connected to a slide rod 21 on the side away from the reciprocating screw 9. A slide sleeve 23 is sleeved on the outside of the slide rod 21, and the barrel 22 is fixedly connected between the nut 8 and the slide sleeve 23.

[0029] Preferably, a feed hopper 2 is provided through the top of the outer casing 1, and a telescopic sleeve 24 is fixedly connected between the feed hopper 2 and the material cylinder 22. The telescopic sleeve 24 can transfer the material entering the feed hopper 2 into the feed cylinder 22, and an arc-shaped channel is provided in the material cylinder 22 to transfer the material to the shelf 3.

[0030] Working principle: When drying camellia seeds using a multi-layer drying rack, an external power supply can be connected to the motor 15 and it can be started. The motor 15 can drive the turntable 7 to rotate through the connecting shaft 18. When the turntable 7 rotates, it can continuously push and pull the side plate 5 through the connecting rod 6, thereby causing all the guide plates 4 to swing continuously. While the motor 15 drives the connecting shaft 18 to rotate, it can also drive the rotating shaft 17 to rotate through two bevel gears 16. The rotating shaft 17 can drive the drive roller 20 to rotate. With the support of the driven roller 11, the drive roller 20 can drive the belt 12 to run. At this time, the belt 12 can drive the gear 10 to rotate intermittently through the rack 19 intermittently set on its outside. Since gear 10 can drive reciprocating screw 9 to rotate, thereby driving screw nut 8 to drive material cylinder 22 to move back and forth in the vertical direction, the intermittent rotation of gear 10 can cause material cylinder 22 to pause intermittently during the lifting and reciprocating motion. Therefore, material cylinder 22 will stop regularly at each shelf 3 during the lifting and reciprocating motion. Afterwards, the drying rack can be pushed to the front of the device, and the guide plate 4 can be positioned between the layers of the drying rack. Then, the material can be fed from bottom to top to the feeding hopper 2. At this time, the material will fall from the inside of the telescopic sleeve 24 into the material cylinder 22, and will be transferred to different shelves 3 as the material cylinder 22 stops at different heights. At this time, the material will roll off the inclined shelf 3 and be pushed into the drying rack by the swinging guide plate 4. By repeating this process, the material can be graded and fed into the multi-layer drying rack through the continuous intermittent lifting and reciprocating motion of the material cylinder 22, so as to maintain the consistency of the environment of the material in each layer and thus ensure the drying efficiency and drying effect.

[0031] Example 2 See attached document Figure 5 This application provides a graded feeding device for multi-layer drying racks. Compared with embodiment 1, in order to facilitate the replacement of drying racks, an electric baffle door 25 is fixedly connected inside the feeding hopper 2.

[0032] Working principle: After the previous drying rack is filled with material, the electric baffle door 25 can be closed to block the feed hopper 2. At this time, the material discharged into the feed hopper 2 by the feeder will be temporarily stored inside it, so no further material will be discharged from the shelf 3 and guide plate 4. At this time, the drying rack in front of this device can be replaced, and the electric baffle door 25 can be opened again afterward to continue to grade and feed the next drying rack.

[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
