Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, specifically to a wind classifier. Background Technology

[0002] Vegetable seeds are seeds used for vegetable production and are divided into conventional seeds and hybrid seeds. Conventional vegetable seeds are seeds that vegetables grow naturally, while hybrid vegetable seeds are produced by pollinating them with plants of different characteristics, thereby altering their varietal traits.

[0003] Currently, there are two methods available on the market for removing shriveled and semi-full seeds from vegetable seeds: a small gravity separator and an air pressure separator. The small gravity separator is not ideal for seed selection, and the air pressure separator cannot perform graded removal. This necessitates repeated seed selection during processing, increasing the workload for workers and reducing processing efficiency.

[0004] According to announcement number CN210253114U, a specific gravity-type wheat screening device relates to the field of wheat processing equipment technology. This device includes a feed pipe and a screening box. One end of the feed pipe is fixedly connected to the top side of the screening box. A first vibration motor is fixedly installed on the lower surface of the feed pipe, and a fan is fixedly installed at the top of one end of the feed pipe. A collection box is fixedly connected to the lower part of the feed pipe near the screening box. The collection box has a collection slot inside, and a partition is fixedly connected to the top of the collection box. This specific gravity-type wheat screening device, through the arrangement of the collection box and collection slot, can store small particle impurities. The partition allows small particles mixed in with the wheat to fall into the collection slot through the fan and natural gravity without affecting the downward conveying of the wheat, resulting in cleaner wheat entering the screening box.

[0005] The gravity-based sorting device described above cannot grade and remove vegetable seeds, which means that the seeds need to be repeatedly sorted during the vegetable seed processing, increasing the workload of the staff and reducing the processing efficiency of the vegetable seeds. Therefore, we need to propose a wind-powered grading machine. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a wind-powered grading machine, including a grading box 1, a feeding component 2 for evenly distributing vegetable seeds installed at the top of the grading box 1, a first discharge port 3, a second discharge port 4 and a third discharge port 5 respectively provided at the bottom of the grading box 1, an adjustable baffle mechanism 6 provided at the top of the second discharge port 4 and the second discharge port 4, an axial flow fan 7 installed on one side of the grading box 1, an air supply pipe 8 connected to the air outlet of the axial flow fan 7, the other end of the air supply pipe 8 penetrating and extending into the interior of the grading box 1, and a dust collection component 9 for collecting dust inside the vegetable seeds provided on the other side of the grading box 1.

[0026] Specifically, vegetable seeds are poured into the feeding assembly 2, which then evenly feeds them into the grading box 1. The axial flow fan 7 is activated to blow air onto the vegetable seeds falling into the grading box 1. The airflow propels the vegetable seeds toward the first discharge port 3, the second discharge port 4, and the third discharge port 5. Seeds with higher density travel a shorter distance when exposed to wind, while seeds with lower density travel a longer distance. The seeds can be divided into three quality grades through the first discharge port 3, the second discharge port 4, and the third discharge port 5, thereby avoiding repeated sorting of vegetable seeds, reducing the workload of workers, and improving the processing efficiency of vegetable seeds.

[0027] The space of the second discharge port 4 is equal to the space of the third discharge port 5, and the space of the first discharge port 3 is larger than the space of the second discharge port 4. The setting of the space of the first discharge port 3 facilitates the separation and feeding of vegetable seeds from stones and soil clods.

[0028] The feeding assembly 2 includes a linear electromagnetic feeder 21, which is fixedly installed on the upper surface of the grading box 1. One end of the linear electromagnetic feeder 21 is provided with a hopper 24, and the bottom end of the hopper 24 is connected to the inner cavity of the grading box 1. Vegetable seeds are poured into the linear electromagnetic feeder 21, and then the linear electromagnetic feeder 21 vibrates and the vegetable seeds fall evenly from the hopper 24 into the grading box 1. The linear electromagnetic feeder 21 evenly sprinkles the seeds like a cloth, solving the problem of poor selection effect caused by seed overlap.

[0029] A support frame 22 is installed at the end of the linear electromagnetic feeder 21 furthest from the discharge hopper. A feed hopper 23 is bolted to the inner cavity of the support frame 22. Vegetable seeds are poured into the feed hopper 23, causing them to fall onto the surface of the linear electromagnetic feeder 21, thus enabling the feeder 21 to discharge the seeds. This prevents the seeds from spilling during feeding and improves the stability of the feeding process.

[0030] The baffle mechanism 6 includes a drive motor 61, which is fixedly mounted on the outer wall of the grading box 1 via a mounting bracket. The output shaft of the drive motor 61 is keyed to a rotating rod 62. The other end of the rotating rod 62 passes through the mounting bracket and is equipped with a rotating structure. The other end of the rotating structure is equipped with a support rod 63, which is rotatably connected to the outer surface of the grading box 1 via a bearing. The other end of the support rod 63 passes through the grading box 1 and is equipped with a baffle plate 64. When the drive motor 61 is started, the rotating rod 62 is rotated, which in turn rotates the rotating structure, causing the support rod 63 to rotate the baffle plate 64, thereby adjusting the baffle plate 64. The adjustable baffle plate 64 allows for more flexible handling of seed selection during processing.

[0031] The rotating structure includes an internal gear support bearing 65. The outer ring of the internal gear support bearing 65 is fixedly connected to the inner cavity of the mounting bracket. A rotating seat 66 is fixedly connected to the inner cavity of the internal gear support bearing 65. The surface of the rotating seat 66 is fixedly connected to one end of the support rod 63. A gear 67 is meshed with the inner cavity of the internal gear support bearing 65. The surface of the gear 67 is keyed to one end of the rotating rod 62. The rotating rod 62 drives the gear 67 to rotate. The gear 67 drives the internal gear support bearing 65 to rotate through the meshing connection, causing the rotating seat 66 to drive the support rod 63 to rotate. Through the cooperation between the internal gear support bearing 65 and the gear 67, the flexibility of the baffle plate 64 in adjusting the angle is increased.

[0032] The dust collection assembly 9 includes a dust collector 91, the dust collection port of which is connected to a dust collection pipe 92, the other end of which is connected to the inner cavity of the grading box 1, and a dust discharge port 93 is provided at the bottom of the dust collector 91. When the dust collector 91 is started, it sucks up the dust in the vegetable seeds in the grading box 1 through the dust collection pipe 92 and finally discharges it through the dust discharge port 93.

[0033] A control module 10 is provided on the outer surface of the grading box 1. The control module 10 is electrically connected to the axial flow fan 7. A control button 11 is provided on the surface of the control module 10. By cooperating with the control button 11 and the control module 10, the starting wind speed of the axial flow fan 7 can be controlled.

[0034] In practical use: Vegetable seeds are poured into the feed hopper 23 and then into the linear electromagnetic feeder 21. When the linear electromagnetic feeder 21 vibrates, the vegetable seeds are spread out evenly from the discharge hopper 24 into the grading box 1. The linear electromagnetic feeder 21 spreads the seeds evenly like a cloth. The axial flow fan 7 is started to blow air into the vegetable seeds falling into the grading box 1. The wind force drives the vegetable seeds to move towards the first discharge port 3, the second discharge port 4, and the third discharge port 5. Seeds with higher density have a shorter flight distance when exposed to wind force, while seeds with lower density have a longer flight distance when exposed to wind. The seeds can be divided into three quality grades through the first discharge port 3, the second discharge port 4, and the third discharge port 5, thereby avoiding repeated sorting of vegetable seeds, reducing the workload of workers, and improving the processing efficiency of vegetable seeds.

[0035] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
