Description

Technical Field

[0001] This invention relates to the field of conveying devices, and more particularly to a rotary conveying device for a drying apparatus for hawthorn processing. Background Technology

[0002] In the processing of hawthorn, drying the sliced ​​fresh hawthorn is a crucial step. Traditional drying operations usually rely on manual tray spreading or simple conveying equipment to send the hawthorn slices into the drying room or continuous dryer.

[0003] Existing technologies still have some problems: hawthorn slices after slicing are irregular in shape, sticky on the surface, and vary in size and thickness. When these scattered hawthorn slices are poured onto horizontal conveying equipment (such as belt conveyors or mesh belt conveyors) for flattening, they are prone to piling up, overlapping, and sticking together. During the drying process, the ventilation and heating of the contact areas of the overlapping hawthorn slices are severely hindered, resulting in inconsistent moisture evaporation rates. This directly causes uneven drying and uneven coloring in the same batch of products. Unoverlapping areas may be over-dried or even charred, while overlapping areas are prone to mold during storage due to excessive moisture content, which greatly affects the quality and commercial value of the final product. In addition, manual intervention in flattening is not only labor-intensive and inefficient, but also difficult to match the production rhythm of modern continuous drying lines. Moreover, personnel contact also brings potential food safety risks. Therefore, a rotary conveying device for hawthorn processing drying equipment is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by providing a rotary conveying device for a drying apparatus for hawthorn processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The rotary conveyor has a polygonal trough inside, and the outer periphery of the polygonal trough is connected to a discharge port. Several discharge ports are fixedly connected to the rotary conveyor. The rotary conveyor is equipped with several control devices arranged in a circular array. The control device includes a slide rail, a first spring is fixedly connected between the slide rail and the rotary conveyor, a slider is slidably connected to the outer wall of the slide rail, and a push plate is fixedly connected to the end of the slider. The push plate is slidably connected to the rotary conveyor.

[0008] Both sides of the polygonal trough are provided with several sets of symmetrically arranged bearing blocks in an array. Each set of bearing blocks has six blocks. A second shaft is fixed to one side of the bearing block. A torsion spring is fixed between the bearing block and the rotary conveyor. A gear is fixed to the end of the second shaft. A rack is meshed on the outer wall of each gear. The same mounting plate is fixed to the outer wall of every six racks. The mounting plate is fixed to one side of the rotary conveyor.

[0009] Preferably, a slide rod is fixed to the outer wall of the mounting plate, a second slide rail is slidably connected to the end of the slide rod, a central fixing plate is fixed to the inner side of the second slide rail, the central fixing plate is fixed to the material distribution trough, and a limit block is fixed to the side of the central fixing plate near the rotary conveyor.

[0010] Preferably, a second torsion spring is rotatably connected to the bottom of the discharge port, a placement shell is fixedly connected to the outer wall of the second torsion spring, and a third shaft is fixedly connected between the placement shell and the discharge port.

[0011] Preferably, a gear three is fixedly connected to the end of the torsion spring two, a rack three is meshed with the outer wall of the gear three, and a slide rod two is fixedly connected to the top of the rack three.

[0012] Preferably, a third slide rail is fixedly connected to the outer side of the second slide rail, and a height adjustment groove is provided inside the third slide rail. The second slide rod is slidably connected to the third slide rail through the height adjustment groove.

[0013] Preferably, a fourth shaft is rotatably connected to the inner side of the placement shell, a baffle is fixed to the outer wall of the fourth shaft, a gear four is fixed to the end of the fourth shaft, a torsion spring three is fixed between the gear four and the placement shell, the fourth shaft meshes with the outer wall of the gear four, and the rack plate is fixed to the third slide rail.

[0014] Preferably, each rotary conveyor has a gear ring fixedly connected to the outer wall of the side away from the distribution trough, and a drive gear meshes with the outer wall of the gear ring. Several drive gears are fixedly connected to the same first shaft. A second drive motor is fixedly connected to one side of the frame, and the output shaft of the second drive motor is fixedly connected to the first shaft.

[0015] Preferably, the frame has two rotating shafts internally connected, and the outer walls of the two rotating shafts are fitted with the same spiral conveyor belt. A drive motor is fixedly connected to one side of the frame, and the output shaft of the drive motor is fixedly connected to one of the rotating shafts.

[0016] Compared with existing technologies, the advantages of this invention are as follows:

[0017] This invention utilizes a feeding trough, triangular block guide, and distribution block flow guide design to achieve automatic sliding and uniform distribution of hawthorn slices to the left and right rotary conveyors. A central vertical plate blocks the flow, turning the horizontally lying hawthorn slices into an upright position, ensuring that most slices can smoothly embed into the multi-angled groove branches. For the small number of slices remaining horizontally, a control device pushes a push plate to lift the right end, providing acceleration towards the multi-angled groove entrance in conjunction with the rotation of the rotary conveyor, achieving precise placement into the groove and preventing jamming or abnormal posture. Gear two drives the carrying block to sequentially perform a "contraction-extension" action, gradually limiting the hawthorn slices from the outside in. Combined with the continuous rotation of the rotary conveyor, the hawthorn slices are ultimately stably positioned within the placement shell, ensuring reliable transfer. When the placement shell rotates 90 degrees to directly below, gear four meshes with the fixed rack plate, automatically opening the baffle for precise control of material discharge.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0031] Reference Figure 1 - Figure 10 A rotary conveyor for drying equipment in hawthorn processing includes a frame 1. A feeding trough 3 is fixedly connected to the top of the frame 1. Several distributing troughs 14 are fixedly connected to the bottom of the feeding trough 3. A triangular block 5 is provided between every two distributing troughs 14. Each triangular block 5 is fixedly connected to the feeding trough 3. A feeding circular pipe 17 is fixedly connected to the bottom of each distributing trough 14. Two side distributing blocks 20 are fixedly connected inside each distributing circular pipe 17. A middle vertical plate 18 is fixedly connected inside each side distributing block 20. A rotary conveyor 12 is rotatably connected to both sides of each distributing circular pipe 17.

[0032] The rotary conveyor 12 has a polygonal groove 23 inside, and the outer periphery of the polygonal groove 23 is connected to a discharge port 16. Several discharge ports 16 are fixedly connected to the rotary conveyor 12. Several control devices arranged in a circular array are installed inside the rotary conveyor 12. The control devices include a slide rail 27. A first spring 28 is fixedly connected between the slide rail 27 and the rotary conveyor 12. A slider 26 is slidably connected to the outer wall of the slide rail 27. A push plate 25 is fixedly connected to the end of the slider 26. The push plate 25 is slidably connected to the rotary conveyor 12.

[0033] In this implementation plan, firstly, the cut hawthorn slices are placed into the feeding trough 3. Under the weight of the hawthorn slices themselves and the guiding action of the triangular block 5, they slide into the inside of the distribution trough 14. Subsequently, the hawthorn slices are guided by the distribution blocks 20 on both sides to the left and right rotary conveyors 12 respectively.

[0034] When the hawthorn slices fall onto the central upright plate 18 in a flat position, they will be blocked by the upright plate 18, thus changing from a flat position to an upright position. This design ensures that most of the flat hawthorn slices can stand upright so that they can be smoothly embedded into the various branches of the polygonal groove 23.

[0035] To address the issue of a small number of hawthorn slices remaining flat and stuck in the sharp corners inside the rotary conveyor 12, when the slide rail 27 is resisted by the limit block 36, it extends into the rotary conveyor 12, causing the slider 26 and push plate 25 to move synchronously. The push plate 25 lifts the right end of the hawthorn slices, and simultaneously, the rotary conveyor 12 moves along... Figure 6 Rotating clockwise in the indicated direction, the pushing action coordinates with the rotational motion, allowing this portion of hawthorn slices to fall smoothly into the branch of the polygonal trough 23. The upward pushing force of the pusher plate 25 lifts its right end, thus changing it from lying flat to tilting. Together with the rotary conveyor, it provides the hawthorn slices with an acceleration pointing towards the entrance of the branch of the polygonal trough 23, causing them to slide into the designated position along a predetermined trajectory. Through the combined force control of the pushing action and the rotational drive, the posture and position of the hawthorn slices can be precisely and reliably adjusted to ensure that they fall smoothly into the branch of the polygonal trough 23 and are received by the innermost 34.

[0036] The polygonal groove 23 has several sets of symmetrically arranged bearing blocks 24 on both sides. Each set of bearing blocks 24 has six blocks. A second shaft 29 is fixed to one side of the bearing block 24. A torsion spring 31 is fixed between the bearing block 24 and the rotary conveyor 12. A gear 34 is fixed to the end of the second shaft 29. A rack 32 meshes with the outer wall of each gear 34. The same mounting plate 35 is fixed to the outer wall of every six racks 32. The mounting plate 35 is fixed to one side of the rotary conveyor 12.

[0037] A slide rod 33 is fixedly connected to the outer wall of the mounting plate 35. A second slide rail 19 is slidably connected to the end of the slide rod 33. A central fixing plate 22 is fixedly connected to the inner side of the second slide rail 19. The central fixing plate 22 is fixedly connected to the material distribution trough 14. A limit block 36 is fixedly connected to the side of the central fixing plate 22 near the rotary conveyor 12.

[0038] A second torsion spring 38 is rotatably connected to the bottom of the discharge port 16. A placement shell 13 is fixedly connected to the outer wall of the second torsion spring 38. A third shaft 37 is fixedly connected between the placement shell 13 and the discharge port 16.

[0039] In this embodiment, when the slide bar 33 rotates to the protruding part of the second slide rail 19, it pushes the mounting plate 35 to move towards the center. At this time, the outermost gear 34 first drives the second shaft 29 and the bearing block 24 mounted on it to rotate, so that the bearing blocks 24 on both sides first retract into the rotary conveyor 12, and then extend outward again. The three sets of bearing blocks 24 perform the "retract-extend" action in sequence from the outside to the inside, gradually positioning the hawthorn slices until they are stably clamped between the two sets of bearing blocks 24. During this period, the rotary conveyor 12 continues to rotate for several cycles, and finally the hawthorn slices fall accurately into the placement shell 13.

[0040] Among them, the end of the torsion spring 38 is fixedly connected to the gear 39, the outer wall of the gear 39 is meshed with the rack 31, and the top of the rack 341 is fixedly connected to the slide rod 40.

[0041] The third slide rail 21 is fixedly connected to the outer side of the second slide rail 19. The third slide rail 21 has a height adjustment groove 30. The second slide rod 40 is slidably connected to the third slide rail 21 through the height adjustment groove 30.

[0042] The inner side of the placement shell 13 is rotatably connected to a fourth shaft 43. A baffle 15 is fixed to the outer wall of the fourth shaft 43. A gear 44 is fixed to the end of the fourth shaft 43. A torsion spring 11 is fixed between the gear 44 and the placement shell 13. The fourth shaft 43 meshes with the outer wall of the gear 44. The rack plate 42 is fixed to the third slide rail 21.

[0043] Each rotary conveyor 12 has a gear ring 7 fixedly connected to the outer wall of the side away from the distribution trough 14. The outer wall of the gear ring 7 is meshed with a drive gear 9. Several drive gears 9 are fixedly connected to the same first shaft 10. A second drive motor 6 is fixedly connected to one side of the frame 1. The output shaft of the second drive motor 6 is fixedly connected to the first shaft 10.

[0044] The frame 1 has two rotating shafts 8 internally connected. The outer walls of the two rotating shafts 8 are fitted with the same loop conveyor belt 2. A drive motor 4 is fixedly connected to one side of the frame 1. The output shaft of the drive motor 4 is fixedly connected to one of the rotating shafts 8.

[0045] In this embodiment, after the feeding process is completed, slide bar 2 40 moves down along the height adjustment groove 30 until it reaches the bottom of the third slide rail 21, and rack 3 41 moves up, causing the placement shell 13 to rotate 90 degrees. When the placement shell 13 rotates to the bottom, the gear 44 at its bottom meshes with the fixed rack plate 42. The gear 44 rotates, which in turn causes the fourth shaft 43 to deflect, opening the baffle 15. The hawthorn slices slide out of the placement shell 13 and are evenly discharged onto the surface of the loop conveyor belt 2.

[0046] The rotation of the rotary conveyor 12 is powered by a second drive motor 6, which drives the drive gear 9 and gear ring 7 through the first shaft 10, ultimately realizing the rotational motion of the rotary conveyor 12. The movement of the loop conveyor belt 2 is driven by a first drive motor 4, which directly drives the rotating shaft 8 to rotate, thereby pulling the loop conveyor belt 2 to move continuously.

[0047] Working principle: First, the sliced ​​hawthorn slices are placed into the feeding trough 3. Under the gravity of the hawthorn slices and the guiding action of the triangular block 5, they slide into the inside of the distribution trough 14. Then, the hawthorn slices are guided by the distribution blocks 20 on both sides and are respectively guided to the left and right rotary conveyors 12 to achieve multi-station synchronous feeding control.

[0048] When the hawthorn slices fall onto the central upright plate 18 in a flat position, they are blocked by the upright plate 18, thus changing from a flat state to an upright state. The upright plate 18 forcibly guides and controls the hawthorn slices to stand upright so that they can be smoothly embedded into the various branches of the polygonal groove 23.

[0049] To address the issue of a small number of hawthorn slices remaining flat and stuck in the sharp corners inside the rotary conveyor 12, when the slide rail 27 is resisted by the limit block 36, it extends into the rotary conveyor 12, causing the slider 26 and push plate 25 to move synchronously. The push plate 25 lifts the right end of the hawthorn slices, and simultaneously, the rotary conveyor 12 moves along... Figure 6 The direction shown is rotated clockwise. The pushing action and rotational motion work together to ensure that this part of the hawthorn slices can fall smoothly into the branch of the polygonal trough 23. The upward pushing force of the pusher plate 25 lifts its right end, thus changing it from lying flat to tilting. Together with the rotary conveyor, it provides the hawthorn slices with an acceleration pointing towards the entrance of the branch of the polygonal trough 23, allowing them to slide into the designated position along a predetermined trajectory. Through the combined force control of the pushing action and the rotational drive, the posture and position of the hawthorn slices can be precisely and reliably controlled to ensure that they fall smoothly into the branch of the polygonal trough 23 and are received by the innermost 34.

[0050] Subsequently, when slide bar 33 rotates to the protruding part of the second slide rail 19, it pushes the mounting plate 35 to move towards the center. At this time, the outermost gear 34 first drives the second shaft 29 and the bearing block 24 mounted on it to rotate, causing the bearing blocks 24 on both sides to retract into the rotary conveyor 12 first, and then extend outward again. The three sets of bearing blocks 24 perform the "retract-extend" action in sequence from the outside to the inside, gradually positioning the hawthorn slices until they are stably clamped between the two sets of bearing blocks 24. During this period, the rotary conveyor 12 continues to rotate for several cycles, finally causing the hawthorn slices to fall accurately into the placement shell 13.

[0051] After the feeding process is completed, slide bar 2 40 moves down along height adjustment groove 30 until it reaches the bottom of third slide rail 21. Rack 3 41 moves up, causing placement shell 13 to rotate 90 degrees. When placement shell 13 rotates to the bottom, gear 44 at its bottom meshes with fixed rack plate 42. Gear 44 rotates, which in turn causes fourth shaft 43 to deflect, opening baffle 15. Hawthorn slices slide out of placement shell 13 and are evenly discharged on the surface of loop conveyor belt 2.

[0052] The rotation of the rotary conveyor 12 is powered by the drive motor 6, which drives the drive gear 9 and gear ring 7 through the first shaft 10 to mesh and transmit the rotational motion of the rotary conveyor 12.

[0053] The movement of the loop conveyor belt 2 is driven by the drive motor 4, which directly drives the rotating shaft 8 to rotate, thereby pulling the loop conveyor belt 2 to move continuously.

[0054] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
