Description

Technical Field

[0001] The utility model belongs to the technical field of seed screening, and in particular relates to a high-spectrum seed screening device. Background Art

[0002] The main purpose of seed screening is to improve the overall quality of seeds by removing impurities (such as mud, sand and gravel, crop seeds, weed seeds, galls, husks, etc.), blighted grains and small seeds from seeds, and selecting high-quality seeds that are large, plump and neat, thereby improving the overall quality of seeds.

[0003] In the prior art, a Chinese patent with application number CN202210987781.2 discloses an online seed quality detection device, which includes: a seed transmission system for transmitting target crop seeds; a seed flipping system for flipping target crop seeds when the target crop seeds meet the flipping trigger condition; an image acquisition system including a first camera and a second camera for collecting bilateral image data of the target crop seeds; and a spectrum acquisition system for collecting spectral data of the target crop seeds. The online seed quality detection device provided by the present invention can simultaneously collect bilateral image data of crop seeds through the image acquisition system provided, and realizes the collection of spectral data by adding a spectrum acquisition system, and provides a data analysis basis for the screening of high-quality seeds through high-throughput collection of internal and external information of crop seeds.

[0004] The promotion of single-seed sowing technology has put higher requirements on seed quality. Hyperspectral imaging technology can be used to non-destructively detect seed vitality using the optical properties of seeds. However, the seeds need to be classified after screening. If they are mixed and transported, they are prone to erroneous diversion, which reduces the quality of the seeds. For this reason, we propose a hyperspectral seed screening device.

[0030] Example

[0031] See also Figure 1-Figure 4 , the technical solution provided by this embodiment is as follows:

[0032] A hyperspectral seed screening device comprises a base 1, a single-grain conveyor belt 2, an agricultural spectrum detector 4, a conveyor frame 17, a transfer cylinder 11 and a transfer mechanism, wherein: the single-grain conveyor belt 2 is arranged on the upper side of the base 1, and a plurality of grooves 3 are arranged on the outer side thereof, and the grooves 3 are used to place single-grain seeds to be detected; the agricultural spectrum detector 4 is fixedly connected to the upper side of the base 1, and is located on the upper side of the grooves 3; two conveyor frames 17 are provided and fixedly connected to the top of the base 1, and are respectively used to convey qualified and unqualified seeds; the transfer cylinder 11 is located between the grooves 3 and the conveyor frame 17, and is provided with a grain outlet 12 on the side close to the conveyor frame 17, and is used to transfer seeds to the conveyor frame 17; the transfer mechanism is arranged on the base 1, and is used to control the rotation of the transfer cylinder 11 and then transfer seeds to different conveyor frames 17.

[0033] In a specific embodiment of the utility model, the single-grain conveyor belt 2 is used to convey seeds by single grains. A plurality of evenly distributed grooves 3 are designed on the single-grain conveyor belt 2. A single seed is placed in each groove 3, and then the seeds are continuously conveyed through the single-grain conveyor belt 2 in a circular motion. The agricultural spectrum detector 4 is located on the upper side of the groove 3. When the seeds pass through the lower side of the agricultural spectrum detector 4, the agricultural spectrum detector 4 is used to image the spectrum of the seeds in real time, and the spectrum data of the seeds are classified, thereby detecting qualified and unqualified seeds. The transfer cylinder 11 is used to classify and convey the seeds. The seeds fall from the groove 3 into the transfer cylinder 11, and then fall into the conveying rack 17 through the particle outlet 12. One conveying rack 17 conveys qualified seeds, and the other conveys unqualified seeds. The extended end of the electric push rod 15 pushes the single rod 14 to rotate, and the single rod 14 drives the installation shaft 13 to rotate, and then drives the transfer cylinder 11 to rotate. The particle outlet 12 rotates slightly with the transfer cylinder 11, so that the discharge position of the particle outlet 12 can be accurately adjusted, and the seeds can be transported according to different grades to prevent the mixing of seeds of different grades, so as to ensure the quality of seed production.

[0034] Specifically, the transfer mechanism includes a mounting shaft 13, a single rod 14, an electric push rod 15 and an ear shaft 16. The mounting shaft 13 is rotatably connected to the top of the base 1, the upper end of the mounting shaft 13 is fixedly connected to the transfer cylinder 11, the single rod 14 is fixedly connected to the circumferential surface of the mounting shaft 13, the ear shaft 16 is fixedly connected to the top of the base 1, the bottom of the electric push rod 15 is rotatably connected to the ear shaft 16, and the extended end of the electric push rod 15 is rotatably connected to the single rod 14.

[0035] In a specific embodiment of the utility model, the mounting shaft 13 is used to support the rotation of the transfer cylinder 11. The transfer cylinder 11 and the mounting shaft 13 are concentric. The particle outlet 12 is close to the upper side of the conveying frame 17. The seeds fall into the transfer cylinder 11 from the groove 3, and then fall onto the conveying frame 17 from the particle outlet 12, and continue to be conveyed by the conveying frame 17. When in use, the single rod 14 is pushed to rotate by the extended end of the electric push rod 15, and the single rod 14 drives the mounting shaft 13 to rotate, and then drives the transfer cylinder 11 to rotate. The particle outlet 12 rotates slightly with the transfer cylinder 11, so that the discharge position of the particle outlet 12 can be accurately adjusted, and the seeds can be conveyed according to different grades and categories.

[0036] Specifically, two support frames 7 are fixedly connected to the top of the base 1 , and synchronous wheels 8 are rotatably connected inside the two support frames 7 . The single-grain conveyor belt 2 is transmission-connected between the two synchronous wheels 8 .

[0037] In a specific embodiment of the present utility model, the support frame 7 is used to support the synchronous wheel 8 to rotate, and the synchronous wheel 8 is used to support the single-grain conveyor belt 2 to circulate.

[0038] Specifically, a servo motor 5 is fixedly connected to the top of the base 1, and an output end of the servo motor 5 is fixedly connected to a first transmission wheel 6, wherein the axis of one of the synchronous wheels 8 is fixedly connected to a second transmission wheel 9, and a synchronous belt 10 is connected between the second transmission wheel 9 and the first transmission wheel 6.

[0039] In a specific embodiment of the utility model, the servo motor 5 is used to drive the single-grain conveyor belt 2 to move in a circular motion. When in use, the first transmission wheel 6 is driven to rotate through the output end of the servo motor 5, and the second transmission wheel 9 is driven to rotate under the synchronous action of the synchronous belt 10, and then the synchronous wheel 8 fixed thereto is driven to rotate. The single-grain conveyor belt 2 follows the synchronous wheel 8 to move in a circular motion to realize continuous seed transportation in the groove 3.

[0040] Specifically, the transfer cylinder 11 is close to the lower side of the groove 3 , and the particle outlet 12 is located on the upper side of the conveying frame 17 .

[0041] In a specific embodiment of the present invention, the position of the transfer cylinder 11 is close to the end of the groove 3. As the single-grain conveyor belt 2 circulates, under the action of gravity, the seeds in the groove 3 will fall into the transfer cylinder 11. The diameter of the transfer cylinder 11 is larger than the moving path of the seeds, ensuring the precise movement of the seeds. The length of the extended end of the electric push rod 15 will change the rotation angle of the single rod 14, and the position of the grain outlet 12 changes with the single rod 14. The grain outlet 12 is designed with two positions, which are respectively located on the upper side of different conveying racks 17, so as to transport the seeds according to their classification.

[0042] Working principle: When the seeds pass through the lower side of the agricultural spectrum detector 4, the agricultural spectrum detector 4 will image the seed spectrum in real time, and classify the seed spectrum data, so as to detect qualified and unqualified seeds. The seeds fall from the groove 3 into the transfer cylinder 11, and then fall into the conveying rack 17 through the grain outlet 12. One conveying rack 17 conveys qualified seeds, and the other conveys unqualified seeds. The single rod 14 is pushed to rotate by the extended end of the electric push rod 15, and the single rod 14 drives the installation shaft 13 to rotate, and then drives the transfer cylinder 11 to rotate. The grain outlet 12 rotates slightly with the transfer cylinder 11, so that the discharge position of the grain outlet 12 can be accurately adjusted, and the seeds can be transported according to different grades to prevent the mixing of seeds of different grades, so as to ensure the quality of seed production.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
