When holding the handle and starting the driving structure to make the traveling wheels and the rollers roll, then start the second electric push rod at the bottom of the first mixing chamber, so that the second electric push rod drives the sealing block to move, exposing the discharge port at the bottom of the first mixing chamber, and making the mixed seeds be sown through the seeding pipe along with the movement of the traveling wheels and the rollers;

[0016] Step 2: When sowing small seeds is required, start the first motor on one side of the first moving block to drive the rotating rod and the first baffle to rotate, so that the first baffle rotates into the first groove and is parallel to the first moving block. The first baffle no longer blocks half of the feeding hole, exposing the second mixing chamber. Start the first motor on one side of the second moving block to drive the rotating rod and the second baffle to rotate, so that the second baffle rotates to be perpendicular to the second moving block and away from the second groove. Then start the first electric push rod to drive the first rack and the first connecting block to move downward.

Specific embodiments

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides a grass seed mixed sowing device for grassland establishment, as Figures 1 to 5As shown in the figure, it includes a mounting frame 1. One end of the mounting frame 1 is provided with a driving structure 2. The bottom of the mounting frame 1 is provided with traveling wheels 3. The rear side of the mounting frame 1 is provided with a fixing frame 4. The top of the fixing frame 4 is provided with a seeding box 5. The bottom of the seeding box 5 is fixedly installed with a conveying pipe 6. One end of the conveying pipe 6 is provided with a mounting plate 7 on the outer side. The top of the mounting plate 7 is fixedly installed with the bottom of the seeding box 5. The bottom end of the conveying pipe 6 is provided with a mixing box 8. The top of the mixing box 8 is provided with two storage boxes 9. The bottom of the storage box 9 is fixedly installed with a connecting pipe 10. The bottom of the connecting pipe 10 is fixedly installed with the bottom of the mixing box 8. The bottom of the mixing box 8 is provided with two seeding pipes 11. An inlet hole is opened at the top of the mixing box 8. The bottom of the inlet hole is provided with a fixing plate 12. The fixing plate 12 is located inside the mixing box 8. A moving port is opened in the middle of the fixing plate 12. A first moving block 13 is arranged at the top on one side of the moving port. A first groove is opened on one side of the first moving block 13. A first baffle 14 is arranged at the top of the first moving block 13. A second moving block 15 is arranged at the bottom on the other side of the moving port. A second groove is opened on one side of the second moving block 15. A second baffle 16 is arranged inside the second groove. A moving structure is arranged inside the fixing plate 12 and between the first moving block 13 and the second moving block 15. A first motor 17 is arranged on one side of the first moving block 13 and the second moving block 15. The output end of the first motor 17 is in transmission connection with a rotating rod 18. The rotating rod 18 is rotatably connected to the tops of the first moving block 13 and the second moving block 15. The rotating rod 18 is fixedly installed with the tops of the first baffle 14 and the second baffle 16. The top of the first baffle 14 is in contact with the inner wall of the top of the mixing box 8. Stirring structures 19 are arranged on both sides of the fixing plate 12 inside the mixing box 8.

[0034] The driving structure 2 is installed through the mounting frame 1, the seeding box 5 is installed through the fixing frame 4, and the driving structure 2 enables the traveling wheels 3 to drive the seeding box 5 to roll, thus facilitating seeding. The mixing box 8 and the storage box 9 are easily installed at the bottom of the seeding box 5 through the mounting plate 7. After seeds are placed inside the seeding box 5, the seeds are conveyed through the conveying pipe 6. Since the top of the first baffle 14 fits against the inner wall of the top of the mixing box 8, it shields the inside of the second mixing chamber, and the first baffle 14 shields half of the feed hole, causing the seeds to enter the first mixing chamber of the mixing box 8 through the other half of the feed hole and the moving port. Then, the plant ash and soil inside the first storage box 9 at the top of the first mixing chamber enter the inside of the first mixing chamber through the connecting pipe 10. The seeds inside the first mixing chamber are stirred by the stirring structure 19. After stirring is completed, the mixed seeds enter the seeding pipe 11 from the discharge port at the bottom of the first mixing chamber, and the seeding pipe 11 sows seeds as the traveling wheels 3 move. When sowing 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, causing the first baffle 14 to rotate into the first groove and remain parallel to the first moving block 13. The first baffle 14 no longer shields half of the feed hole, exposing the second mixing chamber. The first motor 17 on one side of the second moving block 15 is started to drive the rotating rod 18 and the second baffle 16 to rotate, causing the second baffle 16 to rotate to a state perpendicular to the second moving block 15 and away from the second groove. Then, the moving structure causes the first moving block 13 and the second baffle 16 to move downward to expose the second mixing chamber, and at the same time, causes the second moving block 15 and the second baffle 16 to move upward, making the second baffle 16 fit against the inner wall of the top of the first mixing chamber, shielding half of the feed hole and shielding the first mixing chamber. Then, the fine seeds are placed inside the placement box and enter the mixing box 8 through the conveying pipe 6 and the other half of the feed hole. Due to the shielding of the second moving block 15 and the first baffle 14, the fine seeds enter the second mixing chamber through the moving port. The fine sand inside the storage box 9 at the top of the second mixing chamber enters the second mixing chamber through the connecting pipe 10, and the stirring structure 19 is started to fully mix the fine sand and the seeds. The mixed seeds are sown by the seeding pipe 11, so that the seeds can be mixed separately with the plant ash, soil, fine seeds and fine sand in the mixing box 8 without affecting each other, promoting the germination and growth of the seeds, preventing the remaining plant ash and fine seeds inside the seeding box 5 from being mixed and burning the seeds, affecting the germination rate of the seeds, facilitating the mixed sowing of grass seeds, and improving the effect of grassland establishment.

[0035] Such as 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 at the rear of the fixing frame 4. Fixed rods 22 are fixedly installed on both sides of the bottom of the mounting plate 7. One end of each fixed rod 22 is fixedly installed with the mixing box 8. The fixed rods 22 are located between the two storage boxes 9. The fixing plate 12 is fixedly installed on the inner walls of the upper and lower sides of the mixing box 8. The moving port is arranged corresponding to the feeding hole. The fixing plate 12 divides the mixing cavity into a first mixing cavity and a second mixing cavity. The two seeding pipes 11 are respectively arranged corresponding to the first mixing cavity and the second mixing cavity.

[0036] The driving structure 2 facilitates the rolling of the traveling wheels 3 and the roller 21, thereby driving the seeding box 5 to move for seeding. Holding the handle 20 facilitates improving the stability of the movement of the seeding box 5, the traveling wheels 3 and the roller 21. The fixed rods 22 facilitate improving the stability of the installation of the mixing box 8 and the mounting plate 7. The moving port and the feeding hole facilitate the seeds or fine seeds conveyed by the conveying pipe 6 to respectively enter the interiors of the first mixing cavity and the second mixing cavity of the mixing box 8, and are respectively seeded through the seeding pipes 11, which facilitates separating and mixing the seeds and the fine seeds in the mixing box 8, facilitating improving the effect of grass seed mixed seeding, and being convenient to use.

[0037] As Figures 2 to 5 Shown, feeding ports are provided on one side of the two storage boxes 9 away from the driving structure 2. The left storage box 9 contains plant ash and soil, and the right storage box 9 contains fine sand. Control valves are provided on one side of the connecting pipes 10 close to the two storage boxes 9. The two connecting pipes 10 are located on the diagonal line at the top of the mixing box 8 and are respectively arranged corresponding to the first mixing cavity and the second mixing cavity.

[0038] The control valve conveys the plant ash and soil inside the left storage box 9 to the interior of the first mixing cavity through the connecting pipe 10, and through the stirring of the stirring structure 19, the seeds are fully mixed with the plant ash and soil. The plant 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 right storage box 9 conveys the fine sand inside it to the interior of the second mixing cavity through the connecting pipe 10, and through the stirring structure 19, the fine sand is fully mixed with the fine seeds. The fine sand can better ensure the uniform distribution of the seeds, and can prevent the fine seeds from being blown away by the wind or washed away by water, fixing the seeds in the soil and reducing the loss of seeds.

[0039] As Figures 5 to 7 Shown, the first moving block 13 and the first baffle 14 are perpendicular to each other, the second moving block 15 and the second baffle 16 are horizontal to each other. The shapes of the first baffle 14 and the second baffle 16 are both semi-circular, and the first baffle 14 is located at the bottom of the feeding hole.

[0040] The first baffle 14 or the second baffle 16 in a semi-circular shape can block half of the discharge hole, facilitating the mixing of seeds and small seeds in the first mixing chamber and the second mixing chamber respectively. Since the first moving block 13 is perpendicular to the first baffle 14, the first baffle 14 is located at the bottom of the discharge hole to block the second mixing chamber. By setting the second moving block 15 and the second baffle 16 horizontally, it is convenient for seeds to enter the inside of the mixing box 8 through the feed hole. Through the blocking of the second mixing chamber by the first moving block 13 and the second baffle 16, the seeds enter the inside of the first mixing chamber through the moving port, thus facilitating the mixing of the seeds with wood ash and soil and facilitating the germination and growth of the seeds.

[0041] As Figures 5 to 8 shown, the moving structure includes a first connecting block 23. One side of the first connecting block 23 is fixedly installed with one side of the first moving block 13. The other side of the first moving 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 engaged with a gear 26. The middle of the gear 26 is fixedly installed with a movable rod. One side of the gear 26 is engaged 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 moving block 15. An installation groove is formed inside the fixing plate 12. Sliding grooves are formed on both sides of the fixing plate 12. The first connecting block 23 and the second connecting block 28 are respectively slidably connected with the sliding grooves. The first rack 24 and the second rack 27 are both slidably connected with the inner wall of the installation groove. The bottom of the first electric push rod 25 is fixedly installed with the inner wall of the bottom of the installation groove. Both ends of the movable rod are rotatably connected with the inner wall of the installation groove.

[0042] When sowing small seeds is required, the first motor 17 on one side of the first moving block 13 causes the rotating rod 18 to drive the first baffle 14 to rotate into the first groove and remain parallel to the first moving block 13. The first baffle 14 no longer blocks half of the feed hole, exposing the second mixing chamber. Start the first motor 17 on one side of the second moving block 15 to cause the rotating rod 18 and the second baffle 16 to rotate to a state perpendicular to the second moving block 15 and move away from the second groove. Then start the first electric push rod 25 to drive the first rack 24 and the first connecting block 23 to move downward. The first connecting block 23 moves along the chute, causing the first moving block 13 and the first baffle 14 to move downward. 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 chute, causing the second moving block 15 and the second baffle 16 to move upward, making the second baffle 16 fit against the inner wall of the top of the first mixing chamber, blocking half of the feed hole and covering the first mixing chamber. This facilitates small seeds to enter the interior of the second mixing chamber, and the fine sand and small seeds in the storage box 9 are mixed through the connecting pipe 10 to ensure the uniform distribution of the seeds, fix the seeds in the soil, and reduce seed loss.

[0043] As Figures 6 to 8 shown, a first sealed telescopic plate 29 is provided at the bottom of the first rack 24 and on one side of the first electric push rod 25. A second sealed telescopic plate 30 is fixedly installed at the bottom of the second rack 27. The bottoms of the first sealed telescopic plate 29 and the second sealed telescopic plate 30 are fixedly installed inside the bottom of the installation groove. The first sealed telescopic plate 29 and the second sealed telescopic plate 30 are arranged corresponding to the chute. The first sealed telescopic plate 29 is in an extended state, and the second sealed telescopic plate 30 is in a contracted state.

[0044] Through the movement of 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 chute on the side of the fixed plate 12 close to the first moving block 13, and the second sealed telescopic plate 30 blocks the chute on the side of the fixed plate 12 close to the second moving block 15, preventing seeds and small seeds from entering the installation groove inside the fixed plate 12, affecting the movement of the first rack 24 and the second rack 27, thus 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.

[0045] As Figures 6 to 7As shown in the figure, the stirring structure 19 includes a second motor 191, which is fixedly installed on the outer wall of the mixing box 8. The output end of the second motor 191 is drivingly connected to a rotating shaft 192. One end of the rotating shaft 192 passes through the second mixing chamber and the fixing plate 12 and is rotatably connected to the inner wall of the first mixing chamber. Stirring rods 193 are fixedly installed on the outer side of the rotating shaft 192. There are two groups of stirring rods 193, and they are respectively located inside the first mixing chamber and the second mixing chamber.

[0046] When seeds or small seeds are located inside the first mixing chamber or the second mixing chamber, start the second motor 191 to drive the rotating shaft 192 to rotate along the inner wall of the second mixing chamber, so that the stirring rods 193 rotate inside the first mixing chamber and the second mixing chamber, fully mixing the plant ash, soil and seeds inside the first mixing chamber, and fully mixing the fine sand and small seeds inside the second mixing chamber, thereby facilitating the improvement of the sowing effect of different seeds.

[0047] As Figure 5 、 Figure 9 shown, two discharge ports are opened at the bottom of the mixing box 8. The two discharge ports are arranged corresponding to the sowing pipes 11. A moving groove is opened on the inner wall of the bottom of the mixing box 8. A fixing block is fixedly installed in the middle of the moving groove. Second electric push rods 31 are fixedly installed on both sides of the fixing block. One end of the second electric push rod 31 is fixedly installed with a sealing block 32. The sealing block 32 is located inside the discharge port. A fixing groove is opened at the bottom of the sealing block 32. An electric telescopic rod 33 is fixedly installed inside the fixing groove. A cleaning block 34 is fixedly installed at the bottom of the electric telescopic rod 33.

[0048] The sealing block 32 is convenient for blocking the discharge port, so that the seeds and small seeds can be mixed. Start the second electric push rod 31 to drive the sealing block 32 to move, so that the sealing block 32 moves into the moving groove to expose the discharge port. Through the two discharge ports, the seeds mixed well inside the first mixing chamber and the second mixing chamber can enter the two sowing pipes 11 respectively for sowing. When the seeds inside the mixing box 8 are sown and the sowing pipes 11 are blocked, start the second electric push rod 31 to drive the sealing block 32 to move into the discharge port, and then start the electric telescopic rod 33 to drive the cleaning block 34 to move up and down, so that the seeds blocked in the sowing pipes 11 are dredged, facilitating the improvement of the sowing efficiency of the sowing pipes 11 and thus facilitating use.

[0049] The present invention also provides a sowing method for a grass seed mixed sowing device for grassland establishment, including the following steps,

[0050] Step 1: Put the seeds into the interior of the sowing box 5, convey them through the conveying pipe 6, enter the interior of the first mixing chamber of the mixing box 8 through the feeding hole and the moving port, use the control valve to let the plant ash and soil in the storage box 9 at the top of the first mixing chamber enter the interior of the first mixing chamber through the connecting pipe 10, and start the second motor 191 to drive the rotating shaft 192 and the stirring rod 193 to rotate, so that the plant ash, soil and seeds are fully mixed. When holding the handle 20 and starting the driving structure 2 to make the traveling wheels 3 and the rollers 21 roll, then start the second electric push rod 31 at the bottom of the first mixing chamber, so that the second electric push rod 31 drives the sealing block 32 to move, exposing the discharge port at the bottom of the first mixing chamber, and making the mixed seeds be sown by the sowing pipe 11 as the traveling wheels 3 and the rollers 21 move;

[0051] Step 2: When sowing small seeds is needed, start the first motor 17 on one side of the first moving block 13 to drive the rotating rod 18 and the first baffle 14 to rotate, so that the first baffle 14 rotates into the first groove and remains parallel to the first moving block 13. The first baffle 14 no longer blocks half of the feeding hole, exposing the second mixing chamber. Start the first motor 17 on one side of the second moving block 15 to drive the rotating rod 18 and the second baffle 16 to rotate, so that the second baffle 16 rotates to a state perpendicular to the second moving block 15 and moves away from the second groove. Then start the first electric push rod 25 to drive the first rack 24 and the first connecting block 23 to move downward. The first connecting block 23 moves along the chute, and makes the first moving block 13 and the first baffle 14 move downward. When the first rack 24 moves, the gear 26 drives the movable rod to rotate along the inner wall of the installation groove, and makes the second rack 27 drive the second connecting block 28 to move upward along the chute, so that the second moving block 15 and the second baffle 16 move upward, and the second baffle 16 fits against the inner wall of the top of the first mixing chamber, blocking half of the feeding hole and blocking the first mixing chamber;

[0052] Step 3: Then put the small seeds into the interior of the sowing box 5, convey them through the conveying pipe 6, enter the interior of the second mixing chamber of the mixing box 8 through the feeding hole and the moving port, use the control valve to let the fine sand in the storage box 9 at the top of the second mixing chamber enter the interior of the second mixing chamber through the connecting pipe 10, and start the second motor 191 to drive the rotating shaft 192 and the stirring rod 193 to rotate, so that the fine sand and the seeds are fully mixed. When holding the handle 20 and starting the driving structure 2 to make the traveling wheels 3 and the rollers 21 roll, then start the second electric push rod 31 at the bottom of the second mixing chamber, so that the second electric push rod 31 drives the sealing block 32 to move, exposing the discharge port at the bottom of the second mixing chamber, and making the mixed seeds be sown by the sowing pipe 11 as the traveling wheels 3 and the rollers 21 move;

[0053] Step 4: When the seeding in the mixing box 8 is completed and the seeding pipe 11 is blocked, start the second electric push rod 31 to drive the sealing block 32 to move into the discharge port, and then start the electric telescopic rod 33 to drive the cleaning block 34 to move up and down, so that the seeds blocked in the seeding pipe 11 are dredged, and then move the electric telescopic rod 33 and the cleaning block 34 back to their original positions.

[0054] Working principle: When in use, put the seeds into the inside of the sowing box 5, convey them through the conveying pipe 6, enter the inside of the first mixing chamber of the mixing box 8 through the feeding hole and the moving port, and use the control valve to make the plant ash and soil in the storage box 9 at the top of the first mixing chamber enter the inside of the first mixing chamber through the connecting pipe 10. Then start the second motor 191 to drive the rotating shaft 192 and the stirring rod 193 to rotate, so that the plant ash, soil and seeds are fully mixed. When holding the handle 20 and starting the driving structure 2 to make the traveling wheels 3 and the rollers 21 roll, then start the second electric push rod 31 at the bottom of the first mixing chamber, so that the second electric push rod 31 drives the sealing block 32 to move, exposing the discharge port at the bottom of the first mixing chamber, and making the mixed seeds be sown through the sowing pipe 11 along with the movement of the traveling wheels 3 and the rollers 21. When sowing fine seeds, start the first motor 17 on one side of the first moving block 13 to drive the rotating rod 18 and the first baffle 14 to rotate, so that the first baffle 14 rotates into the first groove and is parallel to the first moving block 13. The first baffle 14 no longer blocks half of the feeding hole, exposing the second mixing chamber. Start the first motor 17 on one side of the second moving block 15 to drive the rotating rod 18 and the second baffle 16 to rotate, so that the second baffle 16 rotates to be perpendicular to the second moving block 15 and away from the second groove. Then start the first electric push rod 25 to drive the first rack 24 and the first connecting block 23 to move downward. The first connecting block 23 moves along the sliding groove, and makes the first moving block 13 and the first baffle 14 move downward. When the first rack 24 moves, the gear 26 drives the movable rod to rotate along the inner wall of the installation groove, and makes the second rack 27 drive the second connecting block 28 to move upward along the sliding groove, so that the second moving block 15 and the second baffle 16 move upward, making the second baffle 16 fit with the inner wall of the top of the first mixing chamber, blocking half of the feeding hole and blocking the first mixing chamber. Then put the fine seeds into the inside of the sowing box 5, convey them through the conveying pipe 6, enter the inside of the second mixing chamber of the mixing box 8 through the feeding hole and the moving port, and use the control valve to make the fine sand in the storage box 9 at the top of the second mixing chamber enter the inside of the second mixing chamber through the connecting pipe 10. Then start the second motor 191 to drive the rotating shaft 192 and the stirring rod 193 to rotate, so that the fine sand and the seeds are fully mixed. When holding the handle 20 and starting the driving structure 2 to make the traveling wheels 3 and the rollers 21 roll, then start the second electric push rod 31 at the bottom of the second mixing chamber, so that the second electric push rod 31 drives the sealing block 32 to move, exposing the discharge port at the bottom of the second mixing chamber, and making the mixed seeds be sown through the sowing pipe 11 along with the movement of the traveling wheels 3 and the rollers 21.

[0055] When the seeding in the mixing box 8 is completed and the seeding pipe 11 is blocked, start the second electric push rod 31 to drive the sealing block 32 to move into the discharge port, and then start the electric telescopic rod 33 to drive the cleaning block 34 to move up and down, so that the seeds blocked in the seeding pipe 11 are dredged, and then move the electric telescopic rod 33 and the cleaning block 34 back to their original positions.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
