Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Seed screening is of great significance in the soybean breeding and planting process. By screening the seeds, soybean seeds of different sizes can be obtained, which has the following benefits: 1. Promote uniform sowing: The size and weight of the seeds affect the uniformity of sowing. Through screening, the seeds can be classified according to size to ensure that the size of each seed is basically the same, which is conducive to uniformity during sowing and improves the utilization rate of seeds. 2. Improve the germination rate of seeds: Through screening, the incomplete, aging or too small seeds can be screened out, and healthy, full and germinating seeds can be selected to improve the germination rate and growth potential of seeds. 3. Ensure breeding quality: Seed screening can screen out impurities and unhealthy seeds, ensure the purity and quality of seeds, and improve the success rate of breeding work. 4. Improve the germination speed of seeds: After screening out high-quality seeds, the nutrient distribution inside the seeds is more even, which is conducive to the water absorption and germination speed of seeds and promotes seed growth. In summary, seed screening is a crucial link in the soybean breeding and planting process. By screening seeds, the quality and germination rate of seeds can be improved, the uniformity of sowing can be promoted, the health and growth vitality of seeds can be ensured, thereby promoting the quality and efficiency of soybean production.
[0024] Embodiment 1:
[0025] Based on the technical defects of the existing technology that it is difficult to separate bad seeds, which reduces the success rate of breeding, please refer to Figure 1-Figure 4The utility model provides a soybean seed screening device for agricultural breeding, which can not only screen the seeds, but also automatically select the bad seeds, thereby ensuring the quality and purity of the seeds and improving the success rate of breeding. The device comprises a bracket 1, the top of the bracket 1 is rotatably connected with a screening cylinder 2 with openings at both ends, a synchronous driving mechanism 3 for providing power for seed screening and removing bad seeds is fixed on the side wall of the bracket 1, a gear ring 4 is meshed on the synchronous driving mechanism 3, the gear ring 4 is fixedly connected to the outer wall of one end of the screening cylinder 2, a transmission shaft 5 is also fixedly connected to the synchronous driving mechanism 3, a crossflow fan blade 6 is fixedly provided on the outer wall of the transmission shaft 5, and the crossflow fan blade 6 is rotatably connected to the inside of the outer shield 7, and the outer shield 7 is fixed to the side wall of the bottom of the receiving hopper 9, and the receiving hopper 9 is directly below the screening cylinder 2; the seeds are poured into the screening cylinder 2 from one end, and then the synchronous driving mechanism 3 is used to drive the screening cylinder 2 and the crossflow fan blades 6 to rotate. After the seeds are screened by the screening cylinder 2, the smaller seeds and bad seeds fall from the bottom of the screening cylinder 2, and the crossflow fan blades 6 rotate to generate wind force. Since most of the bad seeds are shriveled or hollow inside, the bad seeds are lighter in weight. Under the action of wind force, the bad seeds can enter the air duct shell 10, thereby not only screening the seeds, but also automatically selecting the bad seeds.
[0026] To facilitate the simultaneous driving of the sieving drum 2 and the crossflow fan blade 6, please refer to Figure 3 The synchronous drive mechanism 3 includes a motor 31 installed on the side wall of the bracket 1. A main transmission wheel 33 and a spur gear 32 are fixedly arranged on the output shaft of the motor 31. The spur gear 32 is meshed with the ring gear 4. The main transmission wheel 33 is connected to the slave transmission wheel 35 through a transmission rope 34. The slave transmission wheel 35 is fixedly connected to one end of the transmission shaft 5. The motor 31 works and drives the main transmission wheel 33 and the spur gear 32 to rotate. The spur gear 32 meshes with the ring gear 4, thereby driving the screening drum 2 to rotate. At the same time, the main transmission wheel 33 can drive the slave transmission wheel 35 to rotate through the transmission rope 34, and the slave transmission wheel 35 can drive the crossflow fan blade 6 to rotate through the transmission shaft 5.
[0027] To ensure that the seeds can be screened smoothly, the screening drum 2 is tilted, and the tilt angle is 5° to 10°; when the screening drum 2 rotates, the seeds can roll downward along the inside of the screening drum 2.
[0028] In order to achieve seed screening, a honeycomb-shaped screen hole is provided in the middle position of the screening cylinder 2, and the diameter of the screen hole is 2.5㎜~4mm; when the seeds pass through the screen hole, the full seeds will not fall down, but can roll down along the screening cylinder 2, while the smaller seeds and bad seeds can fall from the screen hole to achieve seed screening.
[0029] In order to prevent dust from gathering on the crossflow blades 6 , a pre-filter 8 is installed on the side wall of the outer shield 7 ; the pre-filter 8 is used to block dust in the air and prevent dust from entering the crossflow blades 6 .
[0030] In order to improve the transmission stability of the main transmission wheel 33 and the slave transmission wheel 35, rope grooves are provided on both the main transmission wheel 33 and the slave transmission wheel 35; the rope grooves can prevent the transmission rope 34 from being separated, thereby improving the transmission stability of the two.
[0031] In order to prevent seeds from falling from the outside during screening, the top of the receiving hopper 9 is made open and extends to both sides; the open design can increase the receiving area of the receiving hopper 9, thereby preventing seeds from falling from both sides of the receiving hopper 9 during screening.
[0032] To facilitate the collection of seeds and the separation of bad seeds, the side of the hopper 9 away from the outer shield 7 is connected to the air duct shell 10, and the bottom of the hopper 9 and the air duct shell 10 are respectively placed with a collecting box 11 and a miscellaneous box 12; smaller seeds can fall directly into the collecting box 11, while bad seeds enter the miscellaneous box 12 along the air duct shell 10 so as to be collected separately.
[0033] It can be known from the above embodiments that: the seeds are poured into the screening drum 2 from one end, and then under the action of the synchronous drive mechanism 3, the motor 31 is used to drive the main transmission wheel 33 and the spur gear 32 to rotate, and the spur gear 32 drives the screening drum 2 to rotate by meshing with the ring gear 4. At the same time, the main transmission wheel 33 can drive the slave transmission wheel 35 to rotate through the transmission rope 34, and the slave transmission wheel 35 drives the crossflow fan blade 6 to rotate through the transmission shaft 5. After the seeds are screened by the screening drum 2, smaller seeds and bad seeds fall from the bottom of the screening drum 2, and the crossflow fan blade 6 rotates to generate wind force. Since most of the bad seeds are shriveled or hollow inside, the bad seeds are lighter in weight. Under the action of wind force, the bad seeds can enter the air duct shell 10 and enter the miscellaneous box 12 along the air duct shell 10.
[0034] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
