Description

Technical Field

[0001] This application relates to the field of seed screening machine technology, and more specifically, to a seed screening machine with intelligent particle recognition function. Background Technology

[0002] Seed color sorters utilize optical detection principles and incorporate photoelectric detection sensors and high-speed cameras to intelligently collect seed color information and perform intelligent digital processing, ultimately separating and sieving seeds of different colors. An existing fully automatic seed color sorter, disclosed in patent CN220215795U, incorporates a dust collector assembly and a rolling column. The dust collector assembly removes dust from the inside of the chamber, preventing it from obstructing the camera's view. The rolling column prevents seed blockage inside the feeding trough. However, the inventor believes the following shortcomings still exist in the aforementioned technologies: While the seed color sorters in the literature remove dust from the seeds before color sieving, seeds often contain impurities, broken particles, large flat particles, and large leaf debris. If these are not effectively pre-screened, they can negatively impact the color sieving process. Therefore, we propose a seed sorting machine with intelligent particle recognition capabilities. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a seed sorting machine with intelligent particle recognition function, which solves the technical problem in the prior art that although the seed color sorters in the comparative literature remove dust from the seeds before color sieving, the seeds are often mixed with impurities, broken particles, flat and large particles and large leaf debris. If the initial screening is not effectively performed, it will easily affect the color sieving process. This seed sorting machine realizes the seed color detection and recognition function by using photoelectric detection technology, and uses an air gun device to achieve the purpose of separating and sorting seeds of different colors. Before the seed color sorting, the upper primary screening device uses a double-layer sieve plate to screen out light leaves, flattened seeds, dust particles and debris particles, so that seeds of qualified size can be screened out of impurities after color separation.

[0005] 2. Technical Solution

[0006] This application provides a seed screening machine with intelligent particle recognition function, comprising: a color sorter and a mounting shell for positioning and installing the color sorter. The color sorter is electrically connected to a photoelectric detection sensor. The mounting shell is fixedly connected to a chute, a sorting box, and a primary screening device. The photoelectric detection sensor is detachably installed inside the mounting shell. An air gun is detachably installed on the color sorter. The sorting box is provided with a first sorting port and a second sorting port. The air vent of the air gun is located at the first sorting port. The primary screening device includes a feed hopper. The hopper and the screening shell are fixedly connected. A vibration motor is fixed to the bottom of the screening shell by bolts and threads. Four springs are fixedly connected to the bottom of the screening shell. A vertical rod is fixedly connected between the bottom of the springs and the mounting shell. Two screen plates are fixedly installed inside the screening shell. The bottom plate of the screening shell is inclined towards the hopper. A debris outlet is provided at the end of the screening shell near the hopper. A guide plate is fixedly connected at each screen plate at the end of the screening shell away from the hopper. The guide plate at the bottom is located at the upper end of the chute.

[0007] By adopting the above technical solution, the color sorter utilizes existing technology, by setting up photoelectric detection sensors, signal processing devices, and separation execution devices, to achieve high-speed detection and identification of seed colors by photoelectric detection technology, using seeds that are uniformly fed from the chute. When different colored seeds are detected, the air gun device sprays a high-speed airflow towards the detected colored seeds, causing them to be sprayed to the second sorting port of the sorting box, while seeds of the other color fall smoothly into the first sorting port of the sorting box, thus achieving intelligent identification and sorting of seed colors. Because seeds often contain miscellaneous leaves, in order to ensure proper color sorting, the seeds are placed in the feed hopper before color sorting. Under the action of a vibrating motor and springs, the seeds vibrate and move forward along the two sieve plates inside the screening shell. The upper sieve plate removes light miscellaneous leaves and flattened seeds, while normal seeds fall evenly onto the chute through the corresponding guide plate from the lower sieve plate. This process removes light miscellaneous leaves and flattened seeds, while debris and impurities move from the bottom plate of the screening shell toward the feed hopper and are discharged from the debris outlet, thus achieving the purpose of initial seed screening.

[0008] Optionally, a feeding channel is formed between the mounting shell, the slide, and the sorting box, and an anti-overflow baffle is provided at the bottom of the feeding channel of the mounting shell.

[0009] By adopting the above technical solution, qualified seeds are conveyed from the lower screen plate to the chute, and then fall into the sorting box at the bottom through the chute and the feeding channel.

[0010] Optionally, a bracket is fixedly connected between the mounting shell and the sorting box, and the second sorting port is set at a greater distance from the air hole of the air gun device than the first sorting port.

[0011] By adopting the above technical solution, qualified seeds falling from the chute are separated into different colored seeds by a color sorter, and the detected and identified colored seeds are blown by the air gun device to the second sorting port, thus achieving the purpose of sorting seeds of different colors.

[0012] Optionally, the sieve aperture of the upper sieve plate is larger than that of the sieve aperture of the bottom sieve plate.

[0013] By adopting the above technical solution, the two screen plates can be inclined towards the chute. The upper screen plate will screen out light leaves and flattened seeds, while the lower screen plate will retain qualified seeds and convey them to the chute. The debris and particles will fall onto the bottom plate of the screening shell, then move towards the feed hopper and be discharged from the debris outlet.

[0014] Optionally, the slide is inclined, and the inclined surface of the slide is provided with multiple channels.

[0015] By adopting the above technical solution, the slide can be set with multiple channels to make qualified seeds fall evenly in the direction of the channels, which facilitates photoelectric detection and separation.

Before the seed color sorting, the upper primary screening device uses a double-layer sieve plate to screen out light miscellaneous leaves, flattened seeds, dust particles and debris particles, so that seeds of qualified size can be screened out of impurities after color separation.

The color sorter 1 is electrically connected to a photoelectric detection sensor 13. The mounting shell 12 is fixedly connected to a slide 4, a sorting box 2, and a primary screening device 3. The photoelectric detection sensor 13 is detachably installed inside the mounting shell 12. An air gun device 11 is detachably installed on the color sorter 1. The sorting box 2 is provided with a first sorting port 22 and a second sorting port 23. The air vent of the air gun device 11 is located at the first sorting port 22. The primary screening device 3 includes a feed hopper 31 and a screening shell. 32. The feed hopper 31 and the screening shell 32 are fixedly connected. A vibrating motor 37 is fixed to the bottom of the screening shell 32 by bolt threads. Four springs 35 are fixedly connected to the bottom end of the screening shell 32. A vertical rod 36 is fixedly connected between the bottom end of the springs 35 and the mounting shell 12. Two screen plates 33 are fixedly installed inside the screening shell 32. The bottom plate of the screening shell 32 is inclined towards the feed hopper 31. A debris inlet 321 is provided at the end of the screening shell 32 near the feed hopper 31. A guide plate 34 is fixedly connected at the end of the screening shell 32 away from the feed hopper 31 and at each screen plate 33. The bottom guide plate 34 is located on the chute 4. At the upper end, the color sorter 1 utilizes existing technology, by setting up a photoelectric detection sensor 13, a signal processing device, and a separation execution device, to detect and identify the color of seeds uniformly falling from the chute 4 using photoelectric detection technology. When different colored seeds are detected, the air gun device 11 sprays a high-speed airflow towards the detected colored seeds, causing them to be sprayed to the second sorting port 23 of the sorting box 2, while the other colored seeds fall smoothly into the first sorting port 22 of the sorting box 2. This achieves the purpose of intelligent identification and sorting of particle seed colors, as seeds often contain... To ensure proper color sorting, seeds are placed in the feed hopper 31 before color sorting. A vibrating motor 37 and a spring 35 cause the seeds to vibrate and move forward along the two sieve plates 33 inside the screening shell 32. The upper sieve plate 33 removes light, loose leaves and flattened seeds, while normal seeds are evenly distributed onto the chute 4 via the corresponding guide plate 34 from the lower sieve plate 33. This process removes light, loose leaves and flattened seeds, while debris and particles move from the bottom plate of the screening shell 32 towards the feed hopper 31 and are discharged from the debris outlet 321, thus achieving the initial seed screening.

[0024] Reference Figure 2 and Figure 3 A feeding channel 121 is formed between the mounting shell 12, the slide plate 4 and the sorting box 2, and an anti-overflow baffle 14 is provided at the bottom of the mounting shell 12 at the feeding channel 121. Qualified seeds are conveyed from the lower screen plate 33 to the slide plate 4, and fall to the sorting box 2 at the bottom through the slide plate 4 and the feeding channel 121.

[0025] Reference Figure 1 and Figure 2 A bracket 21 is fixedly connected between the mounting shell 12 and the sorting box 2. The second sorting port 23 is set at a greater distance from the air hole of the air gun device 11 than the first sorting port 22. The qualified seeds falling from the slide plate 4 are separated by the color sorter 1, and the detected and identified color seeds are blown by the air hole of the air gun device 11 and blown to the second sorting port 23 to achieve the purpose of sorting seeds of different colors.

[0026] Reference Figure 2 and Figure 3 The sieve holes of the upper sieve plate 33 are larger than those of the bottom sieve plate 33. The two sieve plates 33 can be inclined towards the chute 4. The upper sieve plate 33 removes light leaves and flattened seeds, while the lower sieve plate 33 retains qualified seeds and conveys them to the chute 4. The debris and particles fall onto the bottom plate of the screening shell 32, then move towards the feed hopper 31 and are discharged from the debris outlet 321.

[0027] Reference Figure 2 and Figure 3 The slide plate 4 is placed at an angle, and the inclined surface of the slide plate 4 is provided with multiple channels 41. By setting multiple channels 41, the slide plate 4 can make qualified seeds fall evenly in the direction of the channels 41, which facilitates photoelectric detection and separation processing.

[0028] Working Principle: The color sorter 1 utilizes existing technology, by setting up a photoelectric detection sensor 13, a signal processing device, and a separation execution device, to detect and identify the color of seeds uniformly fed from the chute 4 using photoelectric detection technology. When different colored seeds are detected, the air gun device 11 sprays a high-speed airflow towards the detected colored seeds, causing them to be sprayed to the second sorting port 23 of the sorting box 2, while seeds of the other color fall smoothly into the first sorting port 22 of the sorting box 2. This achieves the purpose of intelligent identification and sorting of seed colors. Often accompanied by miscellaneous leaves, in order to ensure that color sorting proceeds normally, before color sorting, the seeds are placed in the feed hopper 31. Under the action of the vibrating motor 37 and the spring 35, the seeds are vibrated and moved forward along the two screen plates 33 inside the screening shell 32. The upper screen plate 33 is used to screen out light miscellaneous leaves and flattened seeds, while normal seeds fall evenly onto the chute 4 through the corresponding guide plate 34, thereby achieving the screening out of light miscellaneous leaves and flattened seeds. The debris and particles move from the bottom plate of the screening shell 32 toward the feed hopper 31 and are discharged from the debris outlet 321, thereby achieving the purpose of initial seed screening.
