Technical Field

[0001] The utility model belongs to the research field of seed screening technology, and specifically relates to a spectral imaging seed quality detection and sorting device. Background Art

[0002] The hyperspectral imaging quality detection device is a technology that uses image data from multiple bands to achieve detection. It combines image analysis technology with spectral analysis technology, and simultaneously detects the two-dimensional physical space information and one-dimensional spectral information of the target sample to obtain high-resolution continuous, multi-band image sequence data; by analyzing the hyperspectral image sequence of crop seeds, the external morphology and internal component properties of crop seeds can be detected, and then the seed quality indicators of the corresponding crops can be detected. Combined with seed quality sorting equipment technology, good quality seeds can be selected to further ensure the sowing quality of agricultural production. In this application scenario, after the seed quality is inspected, the seeds need to be quality sorted according to the quality of the seeds.

[0003] The patent with the publication number CN213103304U discloses a seed sorting instrument, including: a conveyor belt, an output mechanism, a seed quality detector and at least one sorting mechanism. Among them, the output mechanism is provided with an output port, and the output port outputs seeds to the conveyor belt; the seed quality detector is located above the conveyor belt; the sorting mechanism includes a receiving channel, a rotary valve and a pair of sorting channels, the receiving channel is located below the output end of the conveyor belt, the rotary valve is connected to the receiving channel and the sorting channel respectively, the rotary valve is electrically connected to the seed quality detector, and the rotary valve is used to select the receiving channel to be connected to one of the sorting channels. When in use, a plurality of output ports are provided on the outer surface of the drum, and the output ports are arranged in a row along the axial direction of the drum, and a plurality of rows of output ports are arranged at intervals on the drum to ensure that the seeds falling from the drum onto the conveyor belt can be arranged in a row at intervals, which is convenient for the seed quality detector to check. After each time the seed quality detector checks a row of seeds, the sorting mechanism can screen all the corresponding rows of seeds, and then screen the next row of seeds after the screening is completed.

[0004] However, in the above technical solution, when seeds fall from the output port to the conveyor belt under the action of gravity, the seeds are generally light in weight and easily bounced after falling, resulting in insufficient uniformity of seed arrangement, irregular sample arrangement, and even intermingling of seed samples between rows and columns, which affects the accuracy of the detection device in obtaining seed object information, and further affects the accuracy of judging whether the seeds are qualified. At the same time, the overlapping of seeds between adjacent rows also affects the accuracy of the sorting device in removing and sorting qualified and unqualified seeds, limiting the overall operation accuracy of the seed quality detection and sorting device. Summary of the invention

[0005] The utility model aims to overcome the problem that the seed sampling arrangement of the existing seed screening device is irregular, resulting in low seed detection and sorting accuracy.

[0006] In order to achieve the above-mentioned purpose, the technical idea adopted by the utility model is: a rotating arrangement frame is added between the output mechanism and the seed quality detection device, and a plurality of arrangement plates arranged at equal intervals are provided on the rotating arrangement frame. After the seeds fall onto the conveyor belt, the position of a row of seeds on the conveyor belt can be adjusted by rotating the arrangement plate, so that the seeds are arranged neatly, and then the seeds in different rows are arranged at equal intervals, which is convenient for subsequent detection devices to detect the quality of seeds. In the process of adjusting the position of the row of seeds by the arrangement plate, the row of seeds can be separated from the next row of seeds to prevent the mixing of seeds in two adjacent rows, so that in the subsequent process of seed quality detection and sorting, the accuracy of seed quality detection can be improved, as well as the accuracy of seed sorting.

After the seeds fall onto the conveyor belt, the position of a row of seeds on the conveyor belt can be fine-tuned by rotating the arrangement plate, so that the seeds are arranged neatly, and then the seeds in different rows are arranged at equal intervals, which is convenient for subsequent detection devices to detect the seed quality. In the process of the arrangement plate adjusting the position of the row of seeds, the row of seeds can be separated from the next row of seeds to prevent the seeds of two adjacent rows from mixing, so that in the subsequent process of seed quality detection and sorting, the accuracy of seed quality detection can be improved, and the accuracy of seed sorting can be improved.

[0020] The utility model provides an arrangement plate including a connecting portion and an arrangement portion, wherein one end of the connecting portion is connected to a rotating shaft, and the other end is connected to the arrangement portion; wherein the arrangement portion is provided with a positioning cavity so as to further fine-tune the position of each seed in the same column so that the seeds in the same column are arranged at equal intervals, thereby further improving the accuracy of seed quality detection and further improving the accuracy of seed sorting.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Example 1

[0035] like Figures 1 to 3As shown, a spectral imaging seed quality detection and sorting device provided by the utility model includes a rotating rack 1, an output device 2, a conveyor belt 3, a detection device 4 and a sorting device 5.

[0036] It should be noted that the present invention does not improve the output device 2 , the conveyor belt 3 , the detection device 4 and the sorting device 5 .

[0037] The output device 2 is a prior art, and the present invention does not make any improvements thereto. For its specific structure and working principle, reference may be made to the output mechanism in the patent with publication number CN213103304U in the background technology.

[0038] Specifically, the output device 2 includes a seed collector 21, a roller 22 and an output port 23. The size of the output port 23 is slightly larger than the seeds to be transported; the roller 22 is in contact with the seed collector 21, and the roller 22 is partially embedded in the seed collector 21 from the open surface, and the roller 22 is located above the conveyor belt 3.

[0039] The working principle of the output device 2 is as follows: the rotation of the drum 22 causes the seeds 6 to enter the output port 23 arranged on the drum 22 from the seed collector 21. During the rotation of the drum 22, the seeds 6 fall from the output port 23 onto the transmission belt 3 under the action of gravity. Since a plurality of horizontal rows of output ports 23 are arranged at equal intervals on the drum 22, the seeds 6 are preliminarily arranged when they fall.

[0040] The detection device 4 is a high-spectral quality detection device; the high-spectral quality detection device adopts multi-narrow band image data technology, which combines imaging technology with spectral technology to detect the two-dimensional geometric space and one-dimensional spectral information of the target, and obtains continuous, narrow-band image data with high spectral resolution; thus, according to the characteristics of the hyperspectral, the seed quality of the corresponding crops can be accurately detected, so that the quality of the seeds can be accurately determined based on the display of the hyperspectral detection image data, and further ensure that the crops can grow stably. In practical applications, the technology that can be used to perform multi-spectral imaging of seeds 6 using color cameras and LED lights adopts an LED lighting multi-spectral imaging system. The detection device 4 detects seed quality as a prior art, and the utility model does not improve on this.

[0041] In actual application, the seeds fall from the output device 2 onto the conveyor belt 3, and then the conveyor belt 3 transports the seeds to the bottom of the detection device 4 so that the detection device 4 can detect the seed quality. After the detection is completed, the seeds fall from the conveyor belt 3 to the sorting device 5.

[0042] It is a prior art that the sorting device 5 sorts seeds, and the present utility model does not make any improvements thereto. For its specific structure and working principle, reference may be made to the seed sorting mechanism in the patent with publication number CN105251698A.

[0043] Specifically, the sorting device 5 includes a plurality of sorting boxes, wherein one sorting box includes a qualified box 51 and an unqualified box 52, the qualified box 51 and the unqualified box 52 are connected as one, and a baffle 54 is correspondingly arranged above the sorting box, and the baffle 54 is connected to the motor 53; when in use, if the detection device 4 detects the seed quality and determines that the seed quality is qualified, the detection device 4 sends the result to the sorting device 5, and the sorting device 5 controls the baffle 54 on the sorting box corresponding to the seed to slide through the electric telescopic push rod on the motor 53 to cover the opening of the unqualified box 52, When the qualified box 51 is opened, the opening of the qualified box 51 is opened, so that the seeds 6 fall from the conveyor belt 3 and directly enter the qualified box 51; if the detection device 4 detects the seed quality and determines that the seed quality is unqualified, the detection device 4 sends the result to the sorting device 5, and the sorting device 5 controls the baffle 54 on the sorting box corresponding to the seed to slide through the motor 53 to cover the opening of the qualified box 51, and at the same time, the opening of the unqualified box 52 is opened, so that the seeds 6 fall from the conveyor belt 3 onto the baffle, and then the seeds 6 are drawn into the unqualified box 52 along the inclined surface of the baffle 54, thereby achieving sorting. Among them, the number and position of the sorting boxes correspond to the output port 23 respectively. The embodiment of the utility model is explained by taking the number of output ports 23 as 6 and the number of sorting boxes as 6 as an example.

[0044] Since the seeds are light in weight, after the seeds fall from the output port 23 of the output device 2 onto the conveyor belt 3 , the seeds in different rows are easily mixed, and then the seeds can be sorted and rearranged by the rotating arrangement rack 1 .

[0045] The improvements of the utility model are described in detail below:

[0046] The rotating arrangement frame 1 is located between the output device 2 and the detection device 4; specifically, the rotating arrangement frame 1 includes a gantry support frame 11, a rotating shaft 12, and a plurality of arrangement plates 13 arranged at equal intervals on the rotating shaft 12. It should be noted that the utility model does not limit the number of the arrangement plates 13, and the embodiment of the utility model is described by taking the number of the arrangement plates 13 as 6 as an example.

[0047] The rotating shaft 12 is arranged at the center of the gantry support frame 11 and is rotatably connected to the gantry support frame 11. Specifically, the rotating shaft 12 is located directly above the conveyor belt 3 so that the arrangement plate 13 can arrange the seeds and adjust the seed positions. In practical applications, the rotation speed of the rotating shaft 12 is slightly greater than the rotation speed of the transmission belt 13, so that the arrangement plate 13 can move the seeds on the conveyor belt 3 to the side where the monitoring device 4 is provided, so as to achieve secondary arrangement of the seeds, that is, further adjustment of the seed positions.

[0048] The arrangement plate 13 includes a connecting portion 13a and an arranging portion 13b; wherein one end of the connecting portion 13a is connected to the rotating shaft 12, and the other end is connected to the arranging portion 13b. The material of the arranging portion 13b is an elastic material, and specifically, the material of the arranging portion 13b can be silicone or rubber. When in use, when the arranging portion 13b is closest to the conveyor belt 3 and then moves away from the transmission belt 3, the corners of the arranging portion 13b are bent and deformed, and thus will not get stuck with the transmission belt 3, thereby ensuring the normal operation of the rotating arrangement frame 1.

[0049] Specifically, the arrangement plate 13 is located above the conveyor belt 3; when in use, the rotating shaft 12 rotates, so that the arrangement plate 13 is close to the conveyor belt 3, and then the arrangement part 13b arranged below the arrangement plate 13 contacts the conveyor belt 3. Since the rotation speed of the rotating shaft 12 is slightly greater than the rotation speed of the conveyor belt 3, after the arrangement part 13b contacts the conveyor belt 3, the seeds 6 located in front of it are rearranged within a certain width range forward, for example, the seeds 6 are rearranged within a range of about 2-3 mm width in front of it, thereby realizing a secondary arrangement of the positions of a column of seeds 6, which is convenient for subsequent detection of the quality of the seeds 6.

[0050] Among them, Figure 3 As shown, the arrangement portion 13b provided in the embodiment of the utility model is a rubber soft scraper, and the corners of the rubber soft scraper are chamfered. In this way, when the rubber soft scraper is about to approach the conveyor belt 3 and is about to move away from the conveyor belt 3, the rubber soft scraper can be bent more conveniently to ensure that the arrangement plate 13 rotates normally around the rotating shaft 12. Example 2

[0051] Based on Example 1, different from Example 1, as shown in 3, the arrangement portion 13b provided in the embodiment of the utility model is provided with a plurality of positioning cavities arranged at equal intervals, and the plurality of positioning cavities respectively correspond to the seed positions preliminarily arranged by the output device 2; in this way, when in use, since the rotation speed of the rotating shaft 12 is slightly greater than the transmission speed of the conveyor belt 13, the arrangement portion 13b drives the seeds to roll forward when it is close to the transmission belt 3, and in the process of rolling, the seeds move toward the center of the positioning cavity under the action of the positioning cavity.

[0052] The arrangement portion 13b is an arc-shaped wave plate, and the positioning cavity is a semicircular cavity. When in use, the seeds roll forward and move along the inner wall of the semicircular cavity toward the center of the semicircular cavity, thereby adjusting the spacing between the seeds in a row of seeds and achieving equal spacing between the seeds in a row. Example 3

[0053] Based on Example 2, different from Examples 1 and 2, the arrangement portion 13b provided in the embodiment of the utility model is a V-shaped corrugated plate, and the positioning cavity of the arrangement portion 13b is a V-shaped cavity; wherein the center angle of the V-shaped cavity is an arc, so that when the seeds 6 are arranged for the second time, the seeds 6 will not be stuck in the center angle of the V-shaped cavity.

[0054] In this way, when the arrangement portion 13b adjusts the spacing between the seeds in a row, the seeds can quickly move toward the center of the V-shaped cavity along the inner side surface of the V-shaped cavity, and the efficiency of adjusting the seed spacing is higher.

[0055] Application examples:

[0056] Step 1: The rotating arrangement frame 1 is arranged between the output device 2 and the detection device 4, and the gantry support frame 11 spans the conveyor belt 3, so that the rotating shaft 2 is located directly above the conveyor belt 3;

[0057] Step 2: Power on the rotating arrangement frame 1, the output device 2, the conveyor belt 3, the detection device 4 and the sorting device 5;

[0058] Step 3: The roller 22 in the output device 2 rotates to transfer the seeds 6 from the seed collector 21 to the conveyor belt 3, and the seeds 6 are preliminarily arranged;

[0059] Step 4: The rotating shaft 2 rotates so that the arrangement plate 13 adjusts the position of the seeds in the same row arranged on the conveyor belt 3 so that the distances between the seeds 6 in different rows are equal; in this step: the positioning cavity of the arrangement portion 13b further fine-tunes the spacing between the seeds 6 in the same row so that the spacing between the seeds in the same row is equal;

[0060] Step 5: The neatly arranged seeds 6 are moved to the bottom of the detection device 4 under the action of the conveyor belt 3 so that the detection device 4 can detect the seed quality;

[0061] Step 6: the detection device 4 sends the detection structure of each seed in the same column to the sorting device 5;

[0062] Step seven: The sorting device 5 controls the movement of the baffle 54 through the motor 53 according to the sorting structure, so as to collect seeds of qualified quality in the qualified box 51, and collect seeds of unqualified quality in the unqualified box 52. At this time, the sorting of seeds in the same column is completed, and this process is repeated to sort the seeds in the next column.
