[0002] Astragalus, a plant belonging to the genus Astragalus in the legume family, is also known as Northeast Astragalus. It is widely cultivated due to its medicinal value.

[0003] Currently, before planting Astragalus membranaceus, the seed coat is quite hard, so the seeds need to be treated. To improve the germination rate, the seeds are treated with sulfuric acid, and sharp stones with a diameter of 1 cm are used. The seeds and stones are mixed in a 1:1 volume ratio in a mixer for 10 minutes to slightly abrade the seed coat, which facilitates water absorption and greatly improves the germination rate. In addition, to prevent pests and diseases, the seeds are treated with phorate granules. After sowing, 48% trifluralin emulsifiable concentrate is sprayed evenly on the soil surface per acre.

[0004] However, when treating seeds, workers need to first use a stirring device to rub the seed coat, and then use a seed mixing device to mix the phorate granules with the astragalus seeds. This is inconvenient to use and the equipment integration is low. Therefore, a seed treatment device before sowing is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-4 As shown, a seed treatment device before sowing includes a tank 11. A motor 12 is fixedly connected to the top of the tank 11, and a rotating shaft 15 is fixedly connected to the output end of the motor 12. The rotating shaft 15 is rotatably connected to the middle of the tank 11. A grinding cylinder 13 is fixedly connected to the top of the tank 11, and a seed mixing cylinder 14 is fixedly connected to the bottom of the tank 11. Two sets of stirring blades 16 are fixedly connected to the rotating shaft 15. The two sets of stirring blades 16 are located inside the grinding cylinder 13 and the seed mixing cylinder 14, respectively. A sieve 17 is fixedly connected to the side of the grinding cylinder 13.

[0025] Before use, fill the grinding cylinder 13 with stones of 1 cm in diameter, then put the Astragalus seeds into the grinding cylinder 13, tilt the tank 11, and start the motor 12. The motor 12 drives the rotating shaft 15 and the stirring blade 16 to rotate. The stirring blade 16 drives the stones to rub the seed coat, causing slight abrasion to the seed coat, which is conducive to water absorption and can greatly improve the germination rate. Then tilt the tank 11, and the grinding cylinder 13 tilts towards the sieve 17. The seeds are sieved out by the sieve 17 and fall into the seed mixing cylinder 14 at the bottom. Phosphate granules are put into the seed mixing cylinder 14, and the seeds are mixed with phosphate granules by a set of stirring blades 16 located inside the seed mixing cylinder 14. This completes the pre-sowing treatment of Astragalus seeds. The above settings integrate seed coat abrasion and seed mixing, which makes it convenient for workers to use.

[0026] Furthermore, such as Figure 1-2 As shown, it also includes a frame 21, the top of which is hinged to the tank body 11. A hydraulic cylinder 22 is hinged to the side of the frame 21. A fixing ring 23 is hinged to the output end of the hydraulic cylinder 22. The tank body 11 passes through the middle of the fixing ring 23 and is fixedly connected to it. A collar 31 is slidably connected to the outer surface of the grinding cylinder 13. An electric push rod 32 is fixedly connected to the inner side wall of the top of the tank body 11. The output end of the electric push rod 32 is fixedly connected to the collar 31.

[0027] During use, the frame 21 is used to fix the tank 11, which can rotate on the frame 21. The hydraulic cylinder 22 hinged on the frame 21 can push the tank 11 to swing, thus tilting the tank 11 to facilitate thorough seed mixing and improve the uniformity of seed and phorate granule mixing. During use, the collar 31 can cover the side of the sieve screen 17. The collar 31 is driven up and down by the spring electric actuator 32 to release the obstruction of the sieve screen 17. During the seed coat abrasion process, the tank 11 can rotate at multiple angles to facilitate the uniformity of seed coat abrasion.

[0028] Furthermore, such as Figure 1 As shown, a first feed pipe 41 is fixedly connected to the top side of the grinding cylinder 13, and a second feed pipe 42 is fixedly connected to the tank body 11. The second feed pipe 42 is located at the top of the seed mixing cylinder 14, and a hopper 43 is fixedly connected to the top of both the first feed pipe 41 and the second feed pipe 42.

[0029] When in use, the first feed pipe 41, the second feed pipe 42 and the upper hopper 43 are provided to facilitate the feeding of astragalus seeds and phorate granules by the staff, making it convenient for the staff to use.

[0030] Furthermore, such as Figure 3 and5 As shown, a ring body 51 is rotatably connected to the bottom of the seed mixing cylinder 14, and a feeding slide 52 is fixedly connected to the ring body 51. A through groove 53 is provided at the bottom of the seed mixing cylinder 14 and the top of the feeding slide 52 at corresponding positions. A fixing arm 62 is hinged to the side of the ring body 51, and a torsion spring is installed at the hinge of the fixing arm 62. A support rod 61 is fixedly connected to the bottom of the tank body 11, and a slot 63 is provided at the end of the support rod 61. The fixing arm 62 is inserted into the slot 63.

[0031] During use, the ring 51 rotates at the bottom of the seed mixing cylinder 14. The rotation of the ring 51 causes the feeding slide 52 to align with the through groove 53 at the bottom of the seed mixing cylinder 14. The feeding slide and the inside of the seed mixing cylinder 14 are connected, which facilitates the discharge of the mixed seeds. During the mixing process, the feeding slide 52 and the through groove 53 are misaligned to close the through groove 53. The fixing arm 62 is inserted into the slot 63 at the end of the support rod 61. The torsion spring keeps the fixing arm 62 inserted into the slot 63, which fixes the ring 51.

[0032] Furthermore, such as Figure 1 As shown, the bottom of the frame 21 is equipped with casters 7. When in use, the casters 7 on the bottom of the frame 21 make it convenient for staff to move the equipment, thus making it convenient for staff to use.

[0033] Working principle: Before use, fill the grinding cylinder 13 with stones of 1 cm diameter. Then, put the Astragalus seeds into the grinding cylinder 13 and tilt the tank 11. Start the motor 12, which drives the rotating shaft 15 and stirring blade 16 to rotate. The stirring blade 16 moves the stones to rub the seed coat, causing slight abrasion to facilitate water absorption and greatly improve the germination rate. After that, tilt the tank 11, and the grinding cylinder 13 tilts towards the sieve 17. The seeds are sieved out by the sieve 17 and fall into the seed mixing cylinder 14 at the bottom. Phoxim granules are added, and the seeds are mixed with the phorate granules by a set of stirring blades 16 located inside the seed mixing cylinder 14. This completes the pre-sowing treatment of Astragalus seeds. The above setup integrates seed coat abrasion and seed mixing, making it convenient for operators to use. During operation, the frame 21 is used to fix the tank 11, which can rotate on the frame 21. The hydraulic cylinder 22 hinged to the frame 21 can push the tank 11 to swing, thus tilting the tank 11 for easy adjustment. Thorough seed mixing improves the uniformity of the mixture between seeds and phorate granules. During use, the collar 31 can cover the side of the sieve screen 17. The collar 31 is driven up and down by the spring electric actuator 32 to release the obstruction of the sieve screen 17. During seed coat abrasion, it allows the tank 11 to rotate at multiple angles, which facilitates the uniformity of seed coat abrasion. The first feed pipe 41, the second feed pipe 42, and the upper hopper 43 facilitate the convenient addition of Astragalus seeds and phorate granules by the staff. For ease of use by staff, the ring 51 rotates at the bottom of the seed mixing cylinder 14. The rotation of the ring 51 causes the feeding slide 52 to align with the through groove 53 at the bottom of the seed mixing cylinder 14. The feeding slide and the inside of the seed mixing cylinder 14 are connected, which facilitates the discharge of the mixed seeds. During the mixing process, the feeding slide 52 and the through groove 53 are misaligned to close the through groove 53. The fixing arm 62 is inserted into the slot 63 at the end of the support rod 61. The torsion spring keeps the fixing arm 62 inserted into the slot 63, thus fixing the ring 51.
