The mixing box 8 and the storage box 9 are conveniently installed at the bottom of the sowing box 5 through the mounting plate 7. After the seeds are placed inside the sowing box 5, the seeds are transported through the conveying pipe 6. Since the top of the first baffle 14 is in contact with the inner wall of the top of the mixing box 8, the inside of the second mixing chamber is shielded, and the first baffle 14 shields half of the feed hole, so that the seeds enter the first mixing chamber of the mixing box 8 through the other half of the feed hole and the moving port, and then the first storage box 9 on the top of the first mixing chamber is placed in the mixing box 8. The wood ash and soil inside enter the first mixing chamber through the connecting pipe 10, and the seeds inside the first mixing chamber are stirred by the stirring structure 19. After the stirring is completed, the mixed seeds enter the sowing tube 11 from the discharge port at the bottom of the first mixing chamber, and the sowing tube 11 is sown with the movement of the walking wheel 3. When it is necessary to sow fine seeds, the first motor 17 on one side of the first moving block 13 is started to drive the rotating rod 18 and the first baffle 14 to rotate, so that the first baffle 14 rotates to the inside of the first groove and keeps parallel with the first moving block 13. The first baffle 14 no longer covers half of the feed hole, exposing the second mixing chamber, and the first moving block 13 is started.

[0020] like Figures 1 to 5As shown, handles 20 are provided on both sides of the mounting frame 1 and on both sides of the seeding box 5, a roller 21 is provided on the rear side of the fixing frame 4, fixing rods 22 are fixedly installed on both sides of the bottom of the mounting plate 7, one end of the fixing rod 22 is fixedly installed on the mixing box 8, the fixing rod 22 is located between the two storage boxes 9, the fixing plate 12 is fixedly installed on the upper and lower inner walls of the mixing box 8, the moving port is arranged corresponding to the feed hole, the fixing plate 12 divides the mixing chamber into a first mixing chamber and a second mixing chamber, and the two seeding tubes 11 are respectively arranged corresponding to the first mixing chamber and the second mixing chamber.

[0021] The driving structure 2 facilitates the rolling of the walking wheel 3 and the roller 21, thereby driving the seeding box 5 to move and sow. The hand-held handle 20 facilitates the movement and stability of the seeding box 5, the walking wheel 3 and the roller 21. The fixing rod 22 facilitates the stability of the installation of the mixing box 8 and the mounting plate 7. The moving port and the feed hole facilitate the seeds or small seeds transported by the conveying pipe 6 to enter the first mixing chamber and the second mixing chamber of the mixing box 8 respectively, and are sown separately through the sowing pipe 11, so that the seeds and small seeds can be mixed separately in the mixing box 8, so as to improve the effect of grass seed mixing and facilitate use.

[0022] like Figures 2 to 5 As shown, the two storage boxes 9 are both provided with a feed port on the side away from the driving structure 2, wood ash and soil are provided inside the left storage box 9, and fine sand is provided inside the right storage box 9.

The two connecting pipes 10 are located on the diagonal line of the top of the mixing box 8, and are respectively provided corresponding to the first mixing chamber and the second mixing chamber.

[0023] The wood ash and soil in the storage box 9 on the left are transported to the inside of the first mixing chamber through the connecting pipe 10 through the control valve, and the seeds are fully mixed with the wood ash and soil through the stirring of the stirring structure 19. The wood ash and soil ensure that the seeds can obtain sufficient nutrients to improve the germination rate of the seeds and the growth quality of the crops. The control valve at the bottom of the storage box 9 on the right transports the fine sand inside it through the connecting pipe 10 to the inside of the second mixing chamber, and the fine sand is fully mixed with the fine seeds through the stirring structure 19. The fine sand can better ensure the uniform distribution of the seeds, prevent the fine seeds from being blown away by the wind or washed away by water, fix the seeds in the soil, and reduce the loss of seeds.

[0024] like Figures 5 to 7 As shown, the first moving block 13 and the first baffle 14 are vertically arranged, the second moving block 15 and the second baffle 16 are horizontally arranged, the first baffle 14 and the second baffle 16 are both semicircular in shape, and the first baffle 14 is located at the bottom of the feed hole.

[0025] The semicircular first baffle 14 or the second baffle 16 can block half of the discharge hole, so that the seeds and small seeds can be mixed in the first mixing chamber and the second mixing chamber respectively. Since the first moving block 13 and the first baffle 14 are vertically arranged, the first baffle 14 is located at the bottom of the discharge hole to block the second mixing chamber. The second moving block 15 and the second baffle 16 are horizontally arranged to facilitate the seeds to enter the mixing box 8 through the feed hole. The first moving block 13 and the second baffle 16 block the second mixing chamber, so that the seeds enter the first mixing chamber through the moving port, thereby facilitating the mixing of the seeds with wood ash and soil, and facilitating the germination and growth of the seeds.

[0026] like Figures 5 to 8 As shown, the movable structure includes a first connecting block 23, one side of the first connecting block 23 is fixedly installed on one side of the first movable block 13, the other side of the first movable block 13 is fixedly installed with a first rack 24, the bottom of the first rack 24 is fixedly installed with a first electric push rod 25, one side of the first rack 24 is meshed with a gear 26, the middle of the gear 26 is fixedly installed with a movable rod, one side of the gear 26 is meshed with a second rack 27, one side of the second rack 27 is fixedly installed with a second connecting block 28, one side of the second connecting block 28 is fixedly installed with the second movable block 15, a mounting groove is provided inside the fixed plate 12, and sliding grooves are provided on both sides of the fixed plate 12, the first connecting block 23 and the second connecting block 28 are slidably connected to the sliding grooves respectively, the first rack 24 and the second rack 27 are slidably connected to the inner wall of the mounting groove, the bottom of the first electric push rod 25 is fixedly installed to the inner wall of the bottom of the mounting groove, and both ends of the movable rod are rotatably connected to the inner wall of the mounting groove.

[0027] When it is necessary to sow small seeds, the first motor 17 on the side of the first moving block 13 is used to make the rotating rod 18 drive the first baffle 14 to rotate into the first groove and keep it parallel to the first moving block 13. The first baffle 14 no longer covers half of the feed hole, exposing the second mixing chamber. The first motor 17 on the side of the second moving block 15 is started to make the rotating rod 18 and the second baffle 16 rotate to keep it vertically with the second moving block 15 and away from the second groove. The first electric push rod 25 is then started to drive the first rack 24 and the first connecting block 23 to move downward. The first connecting block 23 moves along the slide groove, and the first moving block 13 and the second mixing chamber are connected. The first baffle 14 moves downward, and when the first rack 24 moves, the gear 26 drives the movable rod to rotate along the inner wall of the installation groove, and the second rack 27 drives the second connecting block 28 to move upward along the slide groove, so that the second movable block 15 and the second baffle 16 move upward, and the second baffle 16 is fitted with the inner wall of the top of the first mixing chamber to block half of the feed hole and the first mixing chamber, so as to facilitate the small seeds to enter the interior of the second mixing chamber, and mix the fine sand in the storage box 9 with the small seeds through the connecting pipe 10 to ensure the uniform distribution of the seeds, fix the seeds in the soil, and reduce the loss of seeds.

The bottoms of the first sealed telescopic plate 29 and the second sealed telescopic plate 30 are both fixedly installed inside the bottom of the mounting groove. The first sealed telescopic plate 29 and the second sealed telescopic plate 30 are both arranged corresponding to the slide groove. The first sealed telescopic plate 29 is in an extended state, and the second sealed telescopic plate 30 is in a contracted state.

[0029] By moving the first rack 24 and the second rack 27, the first sealed telescopic plate 29 and the second sealed plate can be telescoped, so that the first sealed telescopic plate 29 can block the slide groove on the side of the fixed plate 12 close to the first moving block 13, and the second sealed telescopic plate 30 blocks the slide groove on the side of the fixed plate 12 close to the second moving block 15, preventing seeds and small seeds from entering the mounting groove inside the fixed plate 12, affecting the movement of the first rack 24 and the second rack 27, thereby affecting the movement of the first moving block 13 and the first baffle 14, the second moving block 15 and the second baffle 16, and affecting the mixing and sowing of seeds.

[0030] like Figure 6 to Figure 7As shown, the stirring structure 19 includes a second motor 191, and the second motor 191 is fixedly installed on the outer wall of the mixing box 8. The output end of the second motor 191 is transmission-connected with a rotating shaft 192. One end of the rotating shaft 192 passes through the second mixing chamber and the fixed plate 12 and is rotationally connected to the inner wall of the first mixing chamber. Stirring rods 193 are fixedly installed on the outside of the rotating shaft 192. There are two groups of stirring rods 193, which are respectively located inside the first mixing chamber and the second mixing chamber.

[0031] When seeds or tiny seeds are located inside the first mixing chamber or the second mixing chamber, the second motor 191 is started to drive the rotating shaft 192 to rotate along the inner wall of the second mixing chamber, so that the stirring rod 193 rotates inside the first mixing chamber and the second mixing chamber, and the wood ash, soil and seeds inside the first mixing chamber are fully mixed, and the fine sand and tiny seeds inside the second mixing chamber are fully mixed, thereby improving the sowing effect of different seeds.

[0032] like Figure 5 , Fig. 9 As shown, two discharge ports are provided at the bottom of the mixing box 8, and the two discharge ports are arranged corresponding to the sowing tube 11. A movable groove is provided on the inner wall at the bottom of the mixing box 8, a fixed block is fixedly installed in the middle of the movable groove, second electric push rods 31 are fixedly installed on both sides of the fixed block, a sealing block 32 is fixedly installed at one end of the second electric push rod 31, the sealing block 32 is located in the discharge port, a fixed groove is provided at the bottom of the sealing block 32, an electric telescopic rod 33 is fixedly installed inside the fixed groove, and a cleaning block 34 is fixedly installed at the bottom of the electric telescopic rod 33.

[0033] The sealing block 32 is used to block the discharge port so that the seeds can be mixed with the fine seeds. The second electric push rod 31 is started to drive the sealing block 32 to move, so that the sealing block 32 moves to the inside of the movable groove to expose the discharge port. The seeds mixed in the first mixing chamber and the second mixing chamber are conveniently introduced into the two sowing tubes 11 for sowing through the two discharge ports. When the sowing of seeds in the mixing box 8 is completed and the sowing tube 11 is blocked, the second electric push rod 31 is started to drive the sealing block 32 to move to the inside of the discharge port, and then the cleaning block 34 is driven up and down by starting the electric telescopic rod 33, so that the seeds blocked in the sowing tube 11 are cleared, so as to improve the sowing efficiency of the sowing tube 11, thereby facilitating use.

[0034] The present invention also provides a sowing method of a grass seed mixed sowing device for grassland planting, comprising the following steps: Step 1: Put the seeds into the sowing box 5, transport them through the conveying pipe 6, and enter the first mixing chamber of the mixing box 8 through the feeding hole and the moving port.
