Multiple vertical first electric push rods 2 are connected between the support plate 10 and the connecting plate 3. Two first electric push rods 2 can be set and are respectively located at both ends of the connecting plate 3.

[0020] When dibbling is required, as Figure 1 shown, the support plate 10 supports on the soil surface. The first stepping motor 21 is started to drive the rotating shaft 11 to rotate clockwise. The rotating shaft 11 drives the digging hoes 15 and the inoculation shovels 17 to rotate clockwise. When the digging hoes 15 rotate clockwise, a pit is dug on the soil surface and the dug soil is driven to rotate together. Then, the inoculation shovel 17 that has been conveyed with seeds by the seed supply structure moves to the pit. Along with the rotation and inclination of the inoculation shovel 17, the seeds on it fall into the pit. And when the digging hoes 15 rotate and incline, the soil on them falls into the pit from the end connected to the rotating shaft 11, automatically covering the seeds, improving the dibbling efficiency. Then, the mobile cart 1 is moved to another dibbling position, and the distance between the connecting plate 3 and the support plate 10 is adjusted by extending or shortening the first electric push rod 2, so as to adjust the distance between the support plate 10 and the lowest position of the digging hoes 15, thereby adjusting the digging depth.

[0021] Furthermore, a compression spring 4 is sleeved on the rod section of the connecting rod 5 between the connecting plate 3 and the trolley. The acting force of the compression spring 4 on the connecting plate 3 is downward, so that the support plate 10 fits with the soil surface, and the digging depth is made as consistent as possible.

[0024] Specifically, the vegetable seeding device capable of synchronous soil covering further includes a drill seeding assembly, and the drill seeding assembly includes: A furrow plow 16 fixedly installed on the side wall of the inoculation shovel 17 close to the digging hoe 15 can be fixed by screws; A soil leveling assembly provided on one side of the fan-shaped cylinder shell 9, which is used to push the soil turned out by the furrow plow 16 into the ditch to cover the seeds after sowing.

[0025] When drill seeding is required, the first stepping motor 21 drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the inoculation shovel 17 and the furrow plow 16 thereon to rotate. When the furrow plow 16 rotates into the soil, stop the first stepping motor 21. When the moving vehicle 1 moves forward, the furrow plow 16 can dig a ditch on the soil surface. The seed supply structure continuously conveys seeds, and the seeds falling from the seed outlet directly fall into the ditch to complete the drill seeding operation. The depth of the ditch can be adjusted according to the depth of the furrow plow 16 turning into the soil or the position of the support plate 10.

[0026] Furthermore, the soil leveling assembly includes: A mounting plate 37 longitudinally fixed on the upper sides of the two support plates 10; A soil leveling plate longitudinally arranged between two support plates 10. The soil leveling plate includes an elastic sleeve 31 and an elastic plate 34. The elastic sleeve 31 and the elastic plate 34 can be made of rubber. Both ends of the elastic plate 34 are respectively inserted into two elastic sleeves 31. One end of the elastic sleeve 31 is hinged to the adjacent support plate 10. A tension spring 36 is connected between one end of the elastic plate 34 located in the elastic sleeve 31 and the elastic sleeve 31. The two ends of the tension spring 36 can be respectively hooked to the elastic plate 34 and the elastic sleeve 31. A third stepping motor 32 fixed on a mounting plate 37, which can be fixed by bolts. A driving rod 33 is fixed on the output shaft of the third stepping motor 32, which can be fixed by welding. A pin shaft 29 is fixed at one end of the driving rod 33 away from the third stepping motor 32. An activity groove 35 for the pin shaft 29 to insert and move is formed on the elastic plate 34. During operation, as Figure 4 shown, initially the soil leveling plate is in an arc shape convex to the right, which can gradually guide the soil on the side to the middle to cover the seeds. By starting the third stepping motor 32, the third stepping motor 32 drives the driving rod 33 to rotate. The driving rod 33 drives the soil leveling plate to deform repeatedly and move left and right through the pin shaft 29. When the soil leveling plate is convex to the left, it can also guide the soil in the middle to both sides. The soil covering is automatically carried out after drilling and broadcasting by the soil covering component, improving the working efficiency. In this embodiment, the vegetable seeding device capable of synchronous soil covering further includes a soil scraping component 22. The soil scraping component 22 is arranged on the side of the sector-shaped cylinder shell 9 away from the soil covering component. The soil scraping component 22 includes: A mounting frame 24 longitudinally arranged above two support plates 10. The mounting frame 24 is fixedly connected to the support plate 10 through a vertical third electric push rod 26, which can be fixedly connected by screws.

As Figure 5 shown, when the belt of the belt power mechanism 27 drives the movable plate 30 to move from the middle to the side through the pin shaft 29, the pin shaft 29 first moves downward along the activity groove 35, the pin shaft 29 drives the scraper 23 to move downward through the installation rod 28, and then the scraper 23 moves horizontally to the side. Preferably, the bottom end of the scraper 23 is lower than the lower surface of the support plate 10 when the scraper 23 moves horizontally. The scraper 23 pushes the surface soil from the middle to both sides, which is convenient for seed sowing. Then the belt power mechanism 27 continues to operate, drives the movable plate 30 to move from the side to the middle through the pin shaft 29 on the belt, the pin shaft 29 first moves upward along the activity groove 35, and the pin shaft 29 drives the scraper 23 to move upward through the installation rod 28 to lift the scraper 23 to prevent the scraper 23 from pushing the surface soil to the middle and affecting the sown seeds.

[0028] In a specific implementation, the seed supply structure includes: A seed box 6 fixed above the mobile vehicle 1; A cylinder body 86 fixedly installed at the bottom of the seed box 6, which can be fixed by welding. A plurality of seed inlet holes communicating with the seed outlet at the bottom of the seed box 6 are longitudinally spaced apart at the top of the cylinder body 86. A plurality of seed dropping pipes 7 are connected to the bottom of the cylinder body 86. The number of the seed inlet holes, the seed dropping pipes 7 and the digging hoe 15 is equal and they correspond one by one; A roller 81 rotatably installed coaxially in the cylinder body 86. There is a spacing between the outer side wall of the roller 81 and the inner side wall of the cylinder body 86. A second stepping motor 85 for driving the roller 81 to rotate is fixed at one end of the cylinder body 86; An annular air bag 84 sleeved on the roller 81. The annular air bag 84 can be attached to the inner side wall of the cylinder body 86. One end of the roller 81 penetrates through an air pipe 87. The end of the air pipe 87 outside the roller 81 is connected to an air charging and discharging pump, which can be fixed to the outer side wall of the cylinder body 86 by screws. A branch pipe is provided in the roller 81. One end of the branch pipe is rotatably connected to the air pipe 87, and the other end of the branch pipe is connected to the annular air bag 84; A plurality of adjusting plates 83 circumferentially spaced between the annular air bag 84 and the inner side wall of the cylinder body 86. Both ends of the adjusting plate 83 are fixed to the telescopic ends of the second electric push rods 82. The second electric push rods 82 are fixed on the roller 81. The adjusting plate 83 can squeeze the annular air bag 84 to form a seed transfer groove. Partition air bags are fixed on both sides of the seed inlet holes on the adjusting plate 83 for separating a plurality of seed transfer grooves.

[0029] Specifically, during direct seeding, the seeds in the seed box 6 enter the seed transfer groove through the seed outlet and the seed inlet hole. Along with the rotation of the roller 81 driven by the second stepping motor 85, the roller 81 drives the seeds to rotate. The seeds enter the seed dropping tube 7 and then fall onto the inoculation shovel 17. The size of the seed transfer groove can be adjusted by extending or shortening the second electric push rod 82, thereby regulating the seeding rate of direct seeding; During drilling, the annular airbag 84 is deflated by the air charging and discharging pump. The volume of the annular airbag 84 becomes smaller, forming a channel for the seeds to pass between the inner side wall of the cylinder body 86. The seeds continuously enter the seed dropping tube 7 through the channel and then continuously fall into the furrow from the seed outlet, completing the drilling seeding.

[0030] During broadcasting, the annular airbag 84 is deflated by the air charging and discharging pump. The volume of the annular airbag 84 becomes smaller, forming a channel for the seeds to pass between the inner side wall of the cylinder body 86. The seeds continuously enter the seed dropping tube 7 through the channel and then fall from the seed outlet. At the same time, the first stepping motor 21 drives the rotating shaft 11 to rotate quickly counterclockwise. The rotating shaft 11 drives the digging hoe 15 and the inoculation shovel 17 to rotate quickly counterclockwise, scattering and throwing the seeds falling from the seed outlet for broadcasting. Of course, it is also possible to directly use other seeding components for broadcasting in the prior art without excessive limitation.

[0031] In summary, the present invention provides a vegetable seeding device capable of synchronous soil covering, and its working principle is as follows: When direct seeding is required, as Figure 1 shown, the support plate 10 supports on the soil surface. The first stepping motor 21 is started to drive the rotating shaft 11 to rotate clockwise. The rotating shaft 11 drives the digging hoe 15 and the inoculation shovel 17 to rotate clockwise. When the digging hoe 15 rotates clockwise, a pit is dug on the soil surface and the dug soil is driven to rotate together. Then, the inoculation shovel 17 that has conveyed the seeds through the seed supply structure moves to the pit. Along with the rotation and inclination of the inoculation shovel 17, the seeds on it fall into the pit. And when the digging hoe 15 rotates and inclines, the soil on it falls into the pit from the end connected to the rotating shaft 11, automatically covering the seeds, improving the efficiency of direct seeding. Then, the mobile vehicle 1 moves to another direct seeding position; When drilling is required, the first stepping motor 21 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the inoculation shovel 17 and the furrow plow 16 on it to rotate. When the furrow plow 16 rotates into the soil, the first stepping motor 21 is stopped. When the mobile vehicle 1 moves forward, the furrow plow 16 can dig a furrow on the soil surface. The seed supply structure continuously conveys the seeds, and the seeds falling from the seed outlet directly fall into the furrow, completing the drilling operation; When broadcasting is required, the belt power mechanism 27 is started, and the belt of the belt power mechanism 27 moves, as Figure 5As shown, when the belt of the belt power mechanism 27 drives the movable plate 30 to move from the middle to the side through the pin shaft 29, the pin shaft 29 first moves downward along the movable groove 35. The pin shaft 29 drives the scraping plate 23 to move downward through the mounting rod 28. Then the scraping plate 23 moves horizontally to the side. Preferably, when the scraping plate 23 moves horizontally, the bottom end thereof is lower than the lower surface of the support plate 10. The scraping plate 23 pushes the surface soil from the middle to both sides, facilitating seed sowing. The annular airbag 84 is deflated through the air charging and discharging pump. The volume of the annular airbag 84 becomes smaller, and a channel for seeds to pass through is formed between the inner side wall of the cylinder body 86. Seeds continuously enter the seed dropping tube 7 through the channel and then fall from the seed outlet. At the same time, the first stepping motor 21 drives the rotating shaft 11 to rotate quickly counterclockwise. The rotating shaft 11 drives the digging hoe 15 and the inoculation shovel 17 to rotate quickly counterclockwise, dispersing and throwing out the seeds falling from the seed outlet for sowing. The soil leveling component automatically covers the soil after drilling and sowing, improving the working efficiency.
