Description

Technical Field

[0001] The utility model relates to the technical field of seed selection, in particular to a seed selection device for agricultural production and planting. Background Art

[0002] In order to improve the germination rate during agricultural planting, seed selection is generally required. Salt water seed selection is a commonly used seed selection method. The seeds are soaked in salt water. The full seeds will sink to the bottom of the salt water, while the light and deflated bad seeds float on the top of the salt water. Currently, there is a lack of an efficient and reliable seed selection device.

[0003] Chinese patent publication number CN220160207U discloses a screening and seed selection device for soybean planting. In the existing device, when the outer surface of shriveled or insect-damaged soybeans is attached with high-density stones or sand, the damaged soybeans will sink to the bottom, resulting in poor soybean screening effect.

[0004] In order to improve the seed selection efficiency during use, the above technical solution stirs the salt water and seeds through a stirring device at the bottom, and then makes the bad seeds float on the water surface and are discharged along the water flow by continuously injecting water inward. However, the rotation of the stirring device during use can easily damage the surface of the seeds, and the stirring device can easily block the seeds when the seeds are discharged, preventing some seeds from being unable to be discharged, and the flow speed of the bad seeds floating on the water surface is slow. Utility Model Content

[0005] The main purpose of the utility model is to provide a seed selection device for agricultural production and planting.

[0015] By setting up a disturbance component, during the seed selection process, the driving motor can drive the eccentric wheel to rotate. During the rotation of the eccentric wheel, the connecting frame can be pressed down, so that the connecting frame descends along the limit frame, thereby driving the float bag to descend. After the eccentric wheel is separated from the connecting frame, the float bag will rise due to the buoyancy of the salt water, and then the float bag can be reciprocated and lifted on the surface of the salt water.

[0022] like Figure 1-Figure 3 As shown, a seed selection device for agricultural production and planting provided in this embodiment includes a sorting box 1, a feed hopper 2 is installed in the middle of the top of the sorting box 1, seeds enter the sorting box 1 through the feed hopper 2, a water inlet pipe 3 is installed at the top of the sorting box 1 on one side of the feed hopper 2, and salt water enters the sorting box 1 through the water inlet pipe 3, and a guide rack 4 is installed above the sorting box 1 and below the feed hopper 2. The guide rack 4 can disperse the seeds entering, and a disturbance component 5 is arranged in the sorting box 1. The disturbance component 5 includes a float 501 located below the guide rack 4, and the float 501 can be in the salt water. The floating bag 501 is reciprocated and lifted to disturb it. A connecting frame 502 is installed at one end of the floating bag 501, and the connecting frame 502 can drive the floating bag 501 to move up and down. The outer side of the connecting frame 502 is slidably connected to the limiting frame 503, and the limiting frame 503 can guide the connecting frame 502. The top of the connecting frame 502 extends to the top of the sorting box 1. An eccentric wheel 504 is arranged on the outer side of the top of the connecting frame 502. The eccentric wheel 504 can intermittently contact the connecting frame 502. A driving motor 505 is installed on the eccentric wheel 504, and the driving motor 505 can drive the eccentric wheel 504 to rotate.

[0023] like Figure 2-Figure 3 As shown, the connecting frame 502 is slidably connected to the sorting box 1, and a protrusion for limiting the connecting frame 502 is formed on the connecting frame 502, which can limit and guide the connecting frame 502 through the sorting box 1, and prevent the connecting frame 502 from rising too high to cause the floating bag 501 to contact the material guide frame 4.

[0024] like Figure 1-Figure 3 As shown, a fixing frame 6 is arranged outside the driving motor 505 , the fixing frame 6 is installed on the sorting box 1 , and the fixing frame 6 is in an L-shaped structure, so that the driving motor 505 can be fixed conveniently through the fixing frame 6 .

[0025] like Figure 1-Figure 2 As shown, an inclined guide plate 7 is installed at the bottom of the sorting box 1, which can guide the sorted seeds through the guide plate 7, so that the seeds can be connected to the brine and discharged from the discharge pipe 8. The discharge pipe 8 is arranged at the bottom of the guide plate 7.

[0026] like Figure 1-Figure 2 As shown, a control switch 9 is installed on the outside of the discharge pipe 8, and the control switch 9 is connected to an external control device, so that the discharge pipe 8 can be turned on and off conveniently by the control switch 9.

[0027] like Figure 1-Figure 2As shown, a discharge port 10 is provided in the middle of one side wall of the sorting box 1, and a collecting box 11 is provided outside the discharge port 10, so that bad seeds and excess brine can enter the collecting box 11 from the discharge port 10 during the sorting process.

[0028] like Figure 1-Figure 2 As shown, a filter plate 12 is installed on one side of the collecting box 11, which can separate the bad seeds and brine entering the collecting box 11, and a discharge pipe 13 is installed below the side wall of the collecting box 11 close to the filter plate 12. The separated brine is discharged into an external collecting device through the discharge pipe 13.

[0029] Working principle of the device: When the device is used, a certain amount of salt water is passed through the water inlet pipe 3 into the sorting box 1, and then the seeds are passed through the feed hopper 2 into the sorting box 1. During the process of entering, the seeds are dispersed by the guide rack 4. At this time, the full seeds will settle to the bottom of the salt water, while the light and deflated bad seeds will float on the top of the salt water. Then, salt water is continuously injected into the sorting box 1, and the excess salt water and bad seeds enter the collection box 11 through the discharge port 10. The salt water and bad seeds are separated by the filter plate 12 in the collection box 11, and the separated salt water is discharged through the discharge pipe 13 into the external collection device;

[0030] During the seed selection process, the driving motor 505 drives the eccentric wheel 504 to rotate. During the rotation of the eccentric wheel 504, the connecting frame 502 can be pressed down, so that the connecting frame 502 descends along the limiting frame 503, thereby driving the float 501 to descend. After the eccentric wheel 504 is separated from the connecting frame 502, the float 501 will rise due to the buoyancy of the salt water, and then the float 501 can be reciprocated and lifted on the surface of the salt water. The reciprocating lifting of the float 501 can stir the salt water, thereby preventing some bad seeds from accumulating at the bottom, and can increase the shaking amplitude of the water surface and increase the discharge speed of the bad seeds. The disturbance component 5 is located at the water surface and will not affect the discharge of the seeds, which is convenient to use and improves practicality. After the seed selection is completed, the guide plate 7 guides the seeds to facilitate the seeds to connect with the salt water and be discharged from the discharge pipe 8.

[0031] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
