The alfalfa seeder with high seedling emergence rate according to claim 1, It is characterized in that The conveying unit (7) further comprises a driving mechanism (72) for rotating the conveying member (71), the driving mechanism (72) comprising a double-shaft motor (721) mounted on the surface of the screen drum (1), the upper and lower output ends of the double-shaft motor (721) being respectively connected to an upper transmission rod (722) and a lower transmission rod (723), the surface of the upper transmission rod (722) being fixedly connected to an upper belt pulley (724), the surface of the upper belt pulley (724) being connected to a matching upper transmission toothed belt (725), the upper transmission toothed belt (725) being connected to the upper transmission toothed belt (725) and the upper transmission toothed belt (725) being connected to the upper transmission toothed belt (725). ) is connected to the inner surface of a matching upper pulley 2 (726), the inner wall of the upper pulley 2 (726) is fixedly connected to the surface of a water pipe 3 (56), the surface of the lower transmission rod (723) is fixedly connected to a lower pulley 1 (727), the surface of the lower pulley 1 (727) is connected to a matching lower transmission toothed belt (728), the inner surface of the lower transmission toothed belt (728) is connected to a matching lower pulley 2 (729), and the inner wall of the lower pulley 2 (729) is fixedly connected to the surface of the rotating rod (711).

6. The alfalfa seeder with high seedling emergence rate according to claim 1, It is characterized in that The moving member (2) comprises two L-shaped fixed rods (21), one end of the L-shaped fixed rod (21) is fixedly connected to the surface of the feed barrel (1), and the other end is fixedly connected to a V-shaped support frame (22), two symmetrical moving wheels (23) are installed on the surface of the V-shaped support frame (22), a push rod (24) is fixedly connected to the surface of the L-shaped fixed rod (21), and two symmetrical reinforcing rods (25) are fixedly connected between the corresponding surfaces of the two V-shaped support frames (22).

7. A method for using the alfalfa seeder with a high seedling emergence rate according to claim 1, It is characterized in that The following steps are involved: Step A, when sowing alfalfa seeds, firstly introduce the alfalfa seeds into the feed barrel (1) through the inclined feed pipe (3). When the alfalfa seeds are located in the screening unit (6), the screening unit (6) can have a certain shaking effect during use by combining its own elastic force with the gravity of the alfalfa seeds falling, so as to efficiently screen the alfalfa seeds. When the alfalfa seeds enter the feed barrel (1), the water spraying mechanism (5) should work at the same time. In this way, the screening unit (6) can also use the impact of the falling warm water sprayed by the water spraying mechanism (5) and the gravity of the falling alfalfa seeds to efficiently cooperate with the screening unit (6) to automatically shake and screen the alfalfa seeds. The warm water entering the feed barrel (1) is used to cooperate with the alfalfa seeds entering the feed barrel (1) to soak, so as to ensure that the alfalfa seeds absorb sufficient water before sowing. Step B, the alfalfa seeds after being screened and soaked in the feed cylinder (1) are then introduced into the conveying cylinder (4) for transport and sowing. The warm water entering the feed cylinder (1) is filtered and then introduced into the water spraying mechanism (5) to discharge the warm water entering the feed cylinder (1). Finally, a feed pipe with a control valve between the bottom of the feed cylinder (1) and the top of the conveying cylinder (4) is opened to allow the alfalfa seeds after being screened and soaked in the feed cylinder (1) to enter the conveying cylinder (4) and be transported and sown through the conveying unit (7).
