The medicine mixing box 1 is divided into a seed chamber 102, a water chamber 101 and a medicine chamber 103 in sequence by the partition 3 and the mesh plate 4. The water chamber 101 is arranged between the two partitions 3, and the distance between the two partitions 3 gradually decreases toward the direction close to the water pipe 11; a water pipe 11 is installed at a position corresponding to the water chamber 101 on the medicine mixing box 1, and a solenoid valve is arranged on the water pipe 11, and the mesh plate 4 is arranged at the end position of the partition 3 close to the water pipe 11; feeding ports are opened at positions corresponding to the seed chamber 102 and the medicine chamber 103 on the medicine mixing box 1, and a cover 10 is installed at the feeding port position, and the initial Figure 8The first usage state shown is: the water pipe 11 is located directly above the medicine mixing box 1, the two covers 10 are located on both sides of the water pipe 11, and the distance between the two partitions 3 gradually decreases upward; the covers 10 on both sides are opened to fill the seeds into the seed cavity 102 from the feeding port, the medicine is placed into the medicine cavity 103, and water is passed from the water pipe 11 into the water cavity 101. At this time, during the filling process, the seeds, medicine and water are respectively in different chambers, and the medicine will not be wetted and agglomerated during filling; after the filling is completed, the feeding port and the water pipe 11 are closed; Then rotate the medicine mixing box 1 counterclockwise so that the medicine mixing box 1 gradually rotates from the use state to the state as shown in FIG. Fig. 9 The second use state shown is: the seed chamber 102 is located at the lower position of the medicine mixing box 1, and the water pipe 11 is located at the side of the medicine mixing box 1; during this rotation process, the seeds in the seed chamber 102 gradually collapse and roll toward the direction close to the mesh plate 4, and the water in the water chamber 101 gradually flows toward the mesh plate 4 close to the seed chamber 102, so that the water flows from the mesh plate 4 position corresponding to the seed chamber 102 toward the seeds, and the seeds and water roll and contact from both sides toward the middle position to wet the seeds first; Then continue to rotate the medicine mixing box 1 so that the medicine mixing box 1 is rotated from the use state 2 to the state as shown in FIG. Fig.10 The third use state shown is as follows: the water pipe 11 is located directly below the medicine mixing box 1, and the distance between the two partitions 3 gradually decreases downward; during the rotation process, the water, the soaked seeds and the medicine all roll toward the mesh plate 4, so that the medicine dissolves in the water or directly passes through the mesh plate 4 into the water cavity 101, and then gradually penetrates into the seed cavity 102 to contact the seeds, so that the medicine gradually penetrates into the seeds and contacts them, and avoids the medicine agglomerates from directly contacting the seeds, thereby avoiding uneven seed treatment; Continue to rotate the medicine mixing box 1, so that the medicine mixing box 1 gradually rotates from the use state 3 to the state as shown in FIG.

Both ends of the mounting frame 5 are rotatably connected with a horizontally placed rotating shaft 6 through bearings, and the rotating shaft 6 is fixedly installed between the box cover plate 2 at one end away from the mounting frame 5. A driving motor 7 is installed at one end of the mounting frame 5, and the output shaft of the driving motor 7 is connected to the corresponding rotating shaft 6 through a coupling, so that the continuous rotation of the medicine mixing box 1 is realized by rotating one of the rotating shafts 6 with the driving motor 7.

[0024] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 6 and Figure 8-Figure 11, a drug mixing device for high-yield seed cultivation of corn dry farming, based on embodiment 1, a plurality of dispersion components 8 are arranged on the partition 3, the two ends of the dispersion component 8 close to the seed cavity 102 are in contact with the water cavity 101 and the seed cavity 102 respectively, and the two ends of the dispersion component 8 close to the drug cavity 103 are in contact with the water cavity 101 and the drug cavity 103 respectively, a through groove is opened at a position corresponding to the dispersion component 8 on the partition 3, the dispersion component 8 is provided with a connection box 81 fixed to the inner wall of the through groove, and a box cover is arranged on both sides of the connection box 81, and the connection box 81 is extended in a direction perpendicular to the partition 3, and two slide plates 82 are slidably connected in the extension direction of the connection box 81, and a spring telescopic tube 83 is installed between the two slide plates 82, and an extension rod 85 is connected to one end of the slide plate 82 away from the spring telescopic tube 83, and one end of the extension rod 85 extends out of the connection box 81, and a dispersion disk 86 is installed at one end of the extension rod 85 away from the slide plate 82, when the connection box 81 is in an inclined state or a vertical state, under the action of gravity, The two slide plates 82 will move toward the bottom, and the slide plate 82 near the bottom position will abut against the inner wall of the connecting box 81. When the connecting box 81 rotates with the partition 3 and the medicine mixing box 1, the inclination direction of the connecting box 81 will change continuously, so that the slide plate 82 moves back and forth in the connecting box 81, so that the corresponding extension rods 85 and dispersion plates 86 in the water chamber 101, the seed chamber 102 and the medicine chamber 103 move back and forth, so as to disperse the water, seeds and medicines respectively, especially when the seed chamber 102 is at the bottom, the soaked seeds are dispersed, and when the medicine chamber 103 is at the bottom, the medicines and medicines are dispersed, thereby further improving the efficiency and effect of the medicine mixing operation, and the extension rod 85 and the dispersion plate 86 move naturally under the action of gravity, which can effectively avoid damage to the seeds; by connecting the two slide plates 82 under the setting of the spring telescopic tube 83, the water chamber 101 and the seed chamber 102, as well as the water chamber 101 and the medicine chamber 103 interact with each other, thereby improving the efficiency of the medicine mixing.

[0025] In the present invention, reference is made to Figure 1-Figure 6 and Figure 8-Figure 11 Both ends of the connection box 81 are provided with grooves 811 adapted to the dispersion disk 86, and the center position of the groove 811 is provided with a through hole adapted to the extension rod 85. When one of the slides 82 is in contact with the inner wall of the connection box 81, the dispersion disk 86 corresponding to the slide 82 at the other end is just in contact with the groove 811. Through the setting of the groove 811, while ensuring the movement of the extension rod 85 and the dispersion disk 86 to disperse seeds or water, when the seed cavity 102 is at the top and water flows out, the dispersion disk 86 corresponding to the seed cavity 102 is just attached to the groove 811 and will not extend out, thereby avoiding pressure damage to the rolling seeds in the non-immersed state, thereby further improving the protection effect of seed mixing with medicine.

When the dispersing disk 86 rotates with the medicine mixing box 1 and the partition 3 and reciprocates along the direction of the extension rod 85, the collision of water or seeds with the dispersing groove 861 will cause the dispersing disk 86 and the extension rod 85 to rotate around the extension rod 85, thereby improving the dispersing effect of the dispersing disk 86 on the surrounding water and seeds.

[0027] In the present invention, reference is made to Figure 1-Figure 6 and Figure 8-Figure 11 The two ends of the spring telescopic tube 83 are sealed with the slide plate 82, and a plurality of balls 84 are filled in the spring telescopic tube 83. When the connection box 81 gradually tilts as the partition 3 rotates, the plurality of balls 84 in the spring telescopic tube 83 roll over and intermittently hit the slide plate 82 near the corresponding bottom, so that the dispersing disk 86 extends outward with an intermittent change effect, thereby improving the dispersing effect of the dispersing disk 86 on the surrounding water and seeds and improving the efficiency of the mixing operation.
