[0058] The following is combined with Figures 1 to 7 As shown, this embodiment of the invention provides an integrated millet seedling sowing machine for saline-alkali land, comprising:

[0059] Cart 1, the top of cart 1 has a rectangular hole and a delivery hole 26;

[0060] A seed dispensing component is installed on the top of the trolley 1, and the seed dispensing component is connected to the dispensing hole 26;

[0061] Two storage components are located on top of the trolley 1, and both storage components are used to store millet seedlings.

[0062] Two planting components are provided, both of which are located on the top of the trolley 1 near the rectangular hole. The planting components are used to place millet seedlings on the ground.

[0063] Acid-base adjustment component, which is located on the top of the trolley 1, is used to adjust the acid-base level of the soil.

[0064] The millet seedlings stored by the storage component are used in conjunction with the planting component to achieve the planting of millet seedlings;

[0065] The seed delivery component enables the planting of millet in seed form, allowing this seeder to meet different working conditions.

[0066] The acid-base regulating component outputs water with the appropriate pH level to temporarily change the soil's pH, thereby ensuring that millet seeds can germinate normally and that millet seedlings can survive.

[0067] Furthermore, it also includes:

[0068] Cylinder 3 is located on the top of the trolley 1, and a connecting bracket 4 is provided at the telescopic end of cylinder 3.

[0069] Breaking wheel 5, breaking wheel 5 and connecting frame 4 are fixed, breaking wheel 5 is used to turn the soil;

[0070] The soil covering wheel 36 is located at the bottom of the trolley 1 and is used for covering soil.

[0071] Using traction equipment or pushing the trolley 1 to travel on the ground, the switch of cylinder 3 is turned on. When cylinder 3 works, it drives the connecting frame 4 to descend, which in turn drives the soil-breaking wheel 5 to descend. The switch of soil-breaking wheel 5 is turned on, and the soil-breaking wheel 5 is used to turn the soil on the ground. As the trolley 1 moves, the soil-breaking wheel 5 turns the soil on the ground and then the planting work is carried out. Then, the soil-covering wheel 36 pushes the soil to the millet seeds or seedlings.

[0072] Furthermore, the storage components include:

[0073] Two first support plates 6 are set on the top of the trolley 1. Multiple first rotating shafts are rotatably arranged between the two first support plates 6 at equal distances. A first belt 7 is fitted on each pair of horizontal first rotating shafts. Multiple transmission wheels 18 are set on the side wall of each first support plate 6. Each pair of adjacent first rotating shafts is fixed to the nearest transmission wheel 18. The same transmission belt 17 is fitted on each pair of adjacent transmission wheels 18.

[0074] The first motor 19 is fixed on one of the side walls of the first support plate 6, and the first motor 19 is fixed to the nearest first rotating shaft;

[0075] A conveying assembly is mounted on the trolley 1 and is used to convey millet seedlings on the first belt 7 to the planting assembly.

[0076] Furthermore, the conveying components include:

[0077] The second fixing plate 10 is fixed to the top of the trolley 1. Multiple electric push rods 11 are fixed to the side wall of the second fixing plate 10. Each electric push rod 11 has a push plate 12 at its telescopic end. The multiple push plates 12 correspond one-to-one with the multiple first belts 7. The bottom of the push plate 12 is flush with the top of the first belt 7.

[0078] Two first fixing plates 9 are fixed on the trolley 1. Multiple connecting plates 8 are fixed on the side walls of the two first fixing plates 9, and the multiple connecting plates 8 correspond one-to-one with the multiple first belts 7. The top of the connecting plate 8 is flush with the top of the first belt 7.

[0079] Before planting, the seedlings need to be placed on the surface of multiple first belts 7 connected to the seedling nursery box. When planting, the switch of the first motor 19 is turned on. When the first motor 19 is working, it drives one of the first shafts to rotate, which in turn drives the first belt 7 to move, so that the seedlings on the first belt 7 can be moved to the planting component. By intermittently turning on the switch of the first motor 19, the seedlings can be transported one by one.

[0080] Furthermore, the planting components include:

[0081] Two second support plates 20 are both mounted on the trolley 1 and are located near the rectangular hole. Two second rotating shafts are rotatably mounted between the two second support plates 20, and the same second belt 21 is mounted on the two second rotating shafts.

[0082] Multiple placement plates 22 are arranged at equal intervals on the surface of the second belt 21, and each placement plate 22 is provided with a strong magnet 23 at its end.

[0083] Furthermore, it also includes:

[0084] Two first gears 24 are respectively rotatably mounted on the sidewalls of two second support plates 20 located on the same side of the rectangular hole, and the two first gears 24 are respectively fixed to two second rotating shafts;

[0085] The second motor 25 is mounted on one of the second support plates 20, and the second motor 25 is fixed to the nearest second rotating shaft.

[0086] When the switch of the electric push rod 11 is turned on, the electric push rod 11 drives the push plate 12 to move. When the push plate 12 moves, it first pushes the seedlings on the first belt 7 onto the connecting plate 8, so that the seedlings move on the surface of the connecting plate 8, and then pushes them onto the two placement plates 22. The seedlings are supported by the placement plates 22 on the two second belts 21. The seedlings on the first belt 7 move onto the multiple placement plates 22 in the same way at the same time.

[0087] When the switch of the second motor 25 is turned on, the second motor 25 drives the second shaft to rotate, which in turn causes the second belt 21 to move. Through the action of the two first gears 24, the two second belts 21 move synchronously in opposite directions, so that the seedlings on the two placement plates 22 can fall down as the second belts 21 move. When the two second belts 21 separate, the seedlings are above the ground and fall to the ground. After covering with soil and watering, the planting of seedlings is completed.

[0088] Furthermore, the seed delivery components include:

[0089] Storage box 13 is fixed to the top of trolley 1, and a tube 27 is provided at the bottom of storage box 13;

[0090] The second baffle 35 is fixed inside the injection hole 26;

[0091] The first baffle 34 is rotatably mounted on the second baffle 35, and the first baffle 34 is rotatably connected to the bottom end of the tube body 27. Both the first baffle 34 and the second baffle 35 have through holes at their tops.

[0092] The second gear 28 is fixedly sleeved on the first baffle 34;

[0093] Two fixing blocks 30 are both set on the top of the trolley 1;

[0094] Prism 31 is fixed on two fixed blocks 30. A rack plate 29 is slidably connected to prism 31, and the rack plate 29 and the second gear 28 mesh with each other.

[0095] Spring 32 is fixed to one of the fixing blocks 30, and spring 32 is fixed to rack plate 29;

[0096] Electromagnet 33 is fixed to the end of rack plate 29.

[0097] The second motor 25 operates continuously. When the second motor 25 is working, it drives the strong magnet 23 on the placement plate 22 to periodically approach the electromagnet 33 through the second rotating shaft and the second belt 21. When the strong magnet 23 approaches the electromagnet 33, the electromagnet 33 moves under the action of magnetic force, which drives the rack plate 29 to move. During this process, the spring 32 is stretched. When the rack plate 29 moves, it drives the second gear 28 to rotate, which in turn drives the first baffle 34 to rotate, so that the through holes on the first baffle 34 and the second baffle 35 coincide. At this time, the millet seeds fall through the tube 27 and the through holes on the first baffle 34 and the second baffle 35, and are output through the delivery hole 26 to realize the seed sowing work. When the strong magnet 23 moves away from the electromagnet 33, the rack plate 29 is driven to reset under the action of the spring 32, so that the first baffle 34 and the second baffle 35 are reset, thereby preventing the seeds from falling and realizing the quantitative and fixed-distance planting of seeds.

[0098] Furthermore, the acid-base adjustment component includes:

[0099] Water tank 2 is fixed to the top of trolley 1, and valve 14 is installed through the side wall of water tank 2.

[0100] A connecting pipe 15 is connected to a valve 14, and a sprinkler head 16 is provided at the end of the connecting pipe 15.

[0101] Turning on the valve 14 allows water from the tank 2 to enter the sprinkler head 16 through the valve 14 and connecting pipe 15, and then be output through the sprinkler head 16 to irrigate the millet seeds or seedlings. The water with appropriate acidity or alkalinity temporarily adjusts the soil's pH level so that the millet seeds can germinate normally or the survival rate of the millet seedlings can be guaranteed.

[0102] The specific working method is as follows: When using it, first fill water tank 2 with water of appropriate acidity or alkalinity;

[0103] Using traction equipment or pushing the trolley 1 to travel on the ground, the switch of cylinder 3 is turned on. When cylinder 3 works, it drives the connecting frame 4 to descend, which in turn drives the soil-breaking wheel 5 to descend. The switch of soil-breaking wheel 5 is turned on, and the soil-breaking wheel 5 is used to turn the soil on the ground. As the trolley 1 moves, the soil-breaking wheel 5 turns the soil on the ground and then carries out planting work. Then, the soil is pushed to the millet seeds or seedlings by the covering wheel 36. Finally, the switch of valve 14 is turned on, so that the water in the water tank 2 can enter the sprinkler head 16 through valve 14 and connecting pipe 15, and then be output through sprinkler head 16 to irrigate the millet seeds or seedlings. The appropriate acid and alkalinity of the water is used to temporarily adjust the acidity and alkalinity of the soil so that the millet seeds can germinate normally or to ensure the survival rate of the millet seedlings.

[0104] When planting millet using seedlings, the seedlings need to be placed on the surface of multiple first belts 7 before planting. When planting, the switch of the first motor 19 is turned on. When the first motor 19 is working, it drives one of the first shafts to rotate, which in turn drives the first belt 7 to move, so that the seedlings on the first belt 7 can be moved to the planting component. By intermittently turning on the switch of the first motor 19, the seedlings can be transported one by one.

[0105] Then turn on the switch of the electric push rod 11. When the electric push rod 11 is working, it drives the push plate 12 to move. When the push plate 12 moves, it first pushes the seedlings on the first belt 7 onto the connecting plate 8, so that the seedlings move on the surface of the connecting plate 8, and then pushes them onto the two placement plates 22. The seedlings are supported by the placement plates 22 on the two second belts 21. The seedlings on the first belt 7 move onto the multiple placement plates 22 in the same way at the same time.

[0106] When the switch of the second motor 25 is turned on, the second motor 25 drives the second shaft to rotate, which in turn causes the second belt 21 to move. Through the action of the two first gears 24, the two second belts 21 move synchronously in opposite directions, so that the seedlings on the two placement plates 22 can fall down with the movement of the second belts 21. When the two second belts 21 separate, the seedlings are above the ground and fall to the ground. After covering with soil and watering, the planting of seedlings is completed.

[0107] During the above process, it is necessary to properly control the intermittent operation of the second motor 25 and the first motor 19. For example, when the second motor 25 stops after working for a certain period of time, the second belt 21 rotates to release all the seedlings. Then, the switch of the first motor 19 on one side is turned on, so that all the first belts 7 on that side move synchronously, so that the seedlings on each of the first belts 7 move forward one unit. Then, the corresponding electric push rod 11 is turned on to complete the synchronous supply of seedlings on all the first belts 7, so that the seedlings move to the placement plate 22 on the second belt 21 again for the next round of sowing. The alternating operation of the two first motors 19 is used to complete the planting of all the seedlings on the first belts 7.

[0108] When planting millet using seeds, the second motor 25 operates continuously. When the second motor 25 operates, it drives the strong magnet 23 on the placement plate 22 to periodically approach the electromagnet 33 via the second rotating shaft and the second belt 21. When the strong magnet 23 approaches the electromagnet 33, the electromagnet 33 moves under the influence of magnetic force, causing the rack plate 29 to move. During this process, the spring 32 is stretched. The movement of the rack plate 29 drives the second gear 28 to rotate, which in turn drives the first baffle 34 to rotate, causing the through holes on the first baffle 34 and the second baffle 35 to overlap. At this time, millet seeds fall through the tube 27 and the through holes on the first and second baffles 34 and 35, and are output through the delivery hole 26, thus achieving seed sowing. When the strong magnet 23 moves away from the electromagnet 33, the rack plate 29 is driven to reset under the action of the spring 32, causing the first and second baffles 34 and 35 to reset, thereby preventing seeds from falling and achieving quantitative and fixed-distance seed planting.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
