Description

Technical Field

[0001] This invention relates to the field of dewing technology for Dalbergia spp. pod seeds, specifically to a device and method for dewing Dalbergia spp. pod seeds. Background Technology

[0002] In the artificial propagation of Dalbergia genus plants, seed propagation is one of the core methods for achieving large-scale seedling production, and the removal of wings from pod seeds is a crucial pretreatment step before sowing. The wing of Dalbergia pod seeds is tightly integrated with the kernel, and the wing texture combines toughness and fibrousness. Current wing removal methods mostly rely on manual peeling or simple mechanical rubbing. Manual peeling is extremely inefficient and cannot meet the seed processing volume requirements of large-scale seedling production; while simple mechanical rubbing can improve efficiency to some extent, improper control of rubbing force can easily damage the kernel, reducing the seed germination rate, and it cannot simultaneously ensure the seed drying state during the wing removal process.

[0003] Because Dalbergia seeds require a specific level of dryness after wing removal to prevent mold and ensure germination activity, current technologies separate the wing removal and drying processes. If seeds are not promptly transferred to drying after wing removal, they are susceptible to moisture absorption due to environmental humidity, leading to increased seed moisture content. This not only increases energy and time costs in subsequent drying processes but may also cause a decline in seed viability due to moisture content fluctuations. Furthermore, existing wing removal equipment lacks a dedicated design for the wing structure of Dalbergia seeds, making it impossible to achieve coordinated control of wing removal efficiency, seed integrity, and drying status. This severely restricts the large-scale and standardized development of Dalbergia seedling cultivation. Therefore, a technical solution that can simultaneously address the issues of efficient wing removal and seed drying is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to provide a device for removing the wings from the seeds of Dalbergia genus pods, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for removing the wings of Dalbergia spp. pod seeds, comprising a shell, a support frame fixedly connected to the bottom of the shell, a bearing sleeve fixedly connected to the middle of the bottom of the shell, a sieving mechanism installed inside the bearing sleeve, a power mechanism installed near the top and outside the shell of the sieving mechanism, a drying mechanism installed at the top inside the shell, and a drop-out opening on the outside of the bearing sleeve at the bottom of the shell.

[0006] Preferably, the screening mechanism includes a screening cylinder rotatably connected to a bearing sleeve. Screening blades are fixedly connected to the bottom of the screening cylinder. A second baffle is placed near the outer side of the bottom of the screening cylinder. A second swing rod is fixedly connected to the inner side of the second baffle. The second swing rod is rotatably connected to the bottom of the screening cylinder. A second limiting block is fixedly connected to the bottom of the screening cylinder near the second baffle. A rotating shaft is fixedly connected to the middle of the bottom of the screening cylinder. A stabilizing frame is rotatably connected to the rotating shaft near the top. The outer side of the stabilizing frame is fixedly connected to the inner wall of the outer shell.

[0007] Preferably, a fixed shaft is fixedly connected to the bottom of the screening cylinder, and a bearing is interference-fitted on the fixed shaft. The screening cylinder is rotatably connected to the bearing sleeve through the fixed shaft and the bearing. A bearing is interference-fitted in the middle of the stabilizing frame, and the rotating shaft is rotatably connected to the middle of the stabilizing frame through the bearing.

[0008] Preferably, screening blades are densely arranged at equal intervals at the bottom of the screening cylinder, and the two sides of the screening blades are arc-shaped.

[0009] Preferably, the bottom of the screening cylinder is provided with a second discharge port corresponding to the second baffle, and two second limiting blocks are provided, one of which is close to the edge of the second baffle, and the other of which is far away from the first block.

[0010] Preferably, the power mechanism includes a first gear, which is fixedly connected to a rotating shaft at the top of the screening cylinder, and a second gear is rotatably connected inside a gear housing, with a motor fixedly connected to the bottom of the gear housing.

[0011] Preferably, the outer rings of the first gear and the second gear mesh with each other, and the motor is fixedly connected to the second gear via a mounting shaft.

[0012] Preferably, the drying mechanism includes a drying cylinder, which is fixedly connected to the top of the rotating shaft. A first collecting seat is fixedly connected to the top of the drying cylinder inside the outer shell. A bottom plate is fixedly connected to the bottom of the drying cylinder inside the outer shell. A heating tube is fixedly connected to the top of the bottom plate on the outer ring of the drying cylinder. A first baffle is placed near the outer ring of the drying cylinder. A first swing rod is fixedly connected to the inner side of the first baffle. The first swing rod is rotatably connected to the rotating shaft near the top. A first limiting block is fixedly connected to the bottom of the drying cylinder near the first baffle.

[0013] Preferably, the outer wall of the drying cylinder is provided with an evenly spaced ring of air grooves, and the bottom of the drying cylinder is provided with a first discharge port on one side next to the first baffle. There are two first limiting blocks, one of which is close to the edge of the first baffle, and the other of which is far away from the first block.

[0014] Another technical solution, a method for removing the wings from Dalbergia odorifera pod seeds, includes the following steps:

[0015] S1. After the heating tube is powered on, it generates heat. The motor drives the second gear to rotate, and the meshing first gear drives the rotating shaft to rotate. At this time, the heating tube generates heat after being powered on. The heat is evenly introduced into the cylinder through the air grooves on the outer wall of the drying cylinder. After the seeds are put into the drying cylinder, they are initially dewinged while rotating with the rotating shaft. At the same time, they absorb heat to achieve drying. The dried seeds enter the screening cylinder through the first discharge port.

[0016] S2. The sieving cylinder rotates synchronously. As the arc-shaped sieving blades inside the sieving cylinder rotate with the cylinder body, they exert a gentle and continuous kneading force on the seeds, and the seed wings and kernels gradually separate during the rotation.

[0017] Compared with the prior art, the present invention provides a device and method for removing the wings of Dalbergia odorifera pod seeds, which has the following beneficial effects:

[0018] 1. The device and method for removing the winged seeds of Dalbergia spp. comprises a screening mechanism in which screening blades with arc-shaped edges are densely arranged at equal intervals at the bottom of the screening cylinder. The screening cylinder is rotated by a power mechanism, and the arc-shaped structure of the blades forms a soft kneading force on the seeds, which can quickly separate the seed wings from the kernels and avoid kernel damage caused by rigid friction. At the same time, the screening cylinder ensures rotational stability through the rotational cooperation of the fixed shaft and the bearing sleeve, further improving the wing removal efficiency and overcoming the limitations of manual or simple machinery.

[0019] 2. The device and method for removing the wings of Dalbergia pod seeds include a drying mechanism and a screening mechanism that are coaxially integrated. The air grooves on the outer wall of the drying cylinder allow the heat generated by the heating tube to penetrate evenly into the cylinder, thus drying the seeds simultaneously. The seeds are directly in a dry environment during the wing removal process, eliminating the need for subsequent transportation. This avoids the increase in moisture content caused by environmental humidity, ensures seed germination activity, and reduces additional energy consumption and time costs.

[0020] 3. The device and method for removing the wings of Dalbergia pods are designed around the characteristics of Dalbergia genus seeds, such as strong seed wings and the need for drying and preservation. The layout of the heating tubes of the drying mechanism and the arc structure of the screening blades are optimized for seed characteristics. Furthermore, the drying and screening actions are linked by the same rotating shaft to achieve coordinated control of wing removal efficiency, kernel integrity, and drying status, thus meeting the needs of large-scale seedling cultivation.

[0039] Screening blades 65 are densely arranged at equal intervals at the bottom of the screening cylinder 64, and the two sides of the screening blades 65 are designed with arc shape.

[0040] The bottom of the screening cylinder 64 is provided with a second discharge port 66 corresponding to the second baffle 67. Two second limiting blocks 68 are provided, one of which is close to the edge of the second baffle 67, and the other is far away from the first block.

[0041] Example 2

[0042] Please see Figure 1-8Furthermore, based on Embodiment 1, the power mechanism 3 includes a first gear 31, which is fixedly connected to the rotating shaft 63 at the top of the screening cylinder 64, and a second gear 32 is rotatably connected to the gear housing 5. A motor 33 is fixedly connected to the bottom of the gear housing 5.

A first collection seat 41 is fixedly connected to the top of the drying cylinder 43 inside the outer shell 1. A bottom plate 48 is fixedly connected to the bottom of the drying cylinder 43 inside the outer shell 1. A heating tube 49 is fixedly connected to the top of the bottom plate 48 on the outer ring of the drying cylinder 43. A first baffle 45 is placed near the outer ring of the drying cylinder 43. A first swing rod 451 is fixedly connected to the inner side of the first baffle 45. The first swing rod 451 is rotatably connected to the rotating shaft 63 near the top. A first limiting block 47 is fixedly connected to the bottom of the drying cylinder 43 near the first baffle 45.

[0045] The outer wall of the drying cylinder 43 is provided with a ring of equally spaced air grooves 44. The bottom of the drying cylinder 43 is provided with a first discharge port 46 next to the first baffle 45. There are two first limiting blocks 47, one of which is close to the edge of the first baffle 45, and the other is far away from the first one.

[0046] Another technical solution, a method for removing the wings from Dalbergia odorifera pod seeds, includes the following steps:

[0047] S1. After the heating tube 49 is powered on, it generates heat. The motor 33 drives the second gear 32 to rotate, and the meshing first gear 31 drives the rotating shaft 63 to rotate. At this time, the heating tube 49 generates heat after being powered on, and it enters the drying cylinder evenly through the air grooves 44 on the outer wall of the drying cylinder 43. After the seeds are put into the drying cylinder 43, they complete the initial dewing process while rotating with the rotating shaft 63, and simultaneously absorb heat to achieve drying. The dried seeds enter the screening cylinder 64 through the first discharge port 46. This integrated design eliminates the interval between the dewing and drying processes, which not only reduces the risk of decreased seed vigor caused by fluctuations in moisture content, but also saves the energy and time of separate drying, achieving cost reduction and efficiency improvement in the pretreatment process, and providing a stable guarantee for the germination rate in the subsequent sowing process.

[0048] S2. The sieving cylinder 64 rotates synchronously. As the cylinder rotates, the arc-shaped sieving blades 65 inside the sieving cylinder 64 exert a gentle and continuous kneading force on the seeds. The seed wings and kernels gradually separate during rotation, while the arc-shaped edges prevent scratching the kernels. The dense arrangement of the sieving blades 65 further expands the contact area with the seeds, improving separation efficiency. This design not only overcomes the efficiency bottleneck of manual dewing but also solves the problem of easily damaging the kernels when using simple mechanical kneading. While ensuring seed integrity, it significantly improves the speed of dewing, providing efficient pretreatment support for large-scale seedling cultivation.

[0049] In actual operation, when this device is used:

[0050] When the heating tube 49 is powered on, it generates heat. The motor 33 drives the second gear 32 to rotate, and the meshing first gear 31 drives the rotating shaft 63 to rotate. At this time, the heating tube 49 generates heat and it enters the drying cylinder evenly through the air grooves 44 on the outer wall of the drying cylinder 43. When the rotating rod rotates clockwise, the first baffle 45 blocks the first discharge port 46 at the bottom of the drying cylinder 43 under the action of centrifugal force, so that the seeds in the drying cylinder will not fall off before drying. After the seeds are put into the drying cylinder 43, they complete the initial dewing and absorb heat to achieve drying while rotating with the rotating shaft 63. After drying, the motor 33 drives the drying cylinder 43 to rotate counterclockwise, opens the first discharge port 46, and the seeds enter the screening cylinder 64 through the first discharge port 46.

[0051] With the cooperation of the two first limiting blocks 47, the first baffle 45 is prevented from shifting too much during the process of blocking the first discharge port 46 away from the first discharge port 46, so as not to lose the purpose of blocking and opening the first discharge port 46.

[0052] At this time, when the rotating rod rotates counterclockwise, the second baffle 67 at the bottom of the sieve cylinder 64 blocks the second discharge port 66 at the bottom of the sieve cylinder 64 under the action of centrifugal force. At this time, the sieve cylinder 64 rotates synchronously. When the arc-shaped sieve blades 65 inside the sieve cylinder 64 rotate with the cylinder body, they form a gentle and continuous kneading force on the seeds, and the seed wings and kernels gradually separate during the rotation.

[0053] With the cooperation of the two second limiting blocks 68, the second baffle 67 is prevented from moving too much during the process of blocking the second discharge port 66 away from the second discharge port 66, so as not to lose the purpose of blocking and opening the second discharge port 66.

[0054] The clockwise and counterclockwise rotation of the rotating rod will not cause the first baffle 45 and the second baffle 67 to simultaneously block the first discharge port 46 and the second discharge port 66. The seeds can be transferred in the drying cylinder 43 and the screening cylinder 64 by rotating the motor 33 clockwise and counterclockwise.

[0055] The first collection port 42 of the first collection seat 41 facilitates the concentrated falling of seeds into the drying cylinder 43. The first gear 31 has a through hole, and the seeds fall into the sieve cylinder 64 through the through hole in conjunction with the second collection port 611 of the second collection seat 61.

[0056] As the seed wings and kernels in the sieving cylinder 64 gradually separate during rotation, the motor 33 continues to drive the rotating rod to rotate clockwise. At this time, the second baffle 67 opens the second discharge port 66, and the separated seeds are discharged through the drop port 8 at the bottom of the outer shell 1. A collection trough is placed at the bottom of the outer shell 1 in advance for collection.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
