[0002] At present, in agricultural planting, conventional manual sowing has low efficiency, poor quality and limited sowing area. Especially in the process of sowing grass seeds on the slope of the river, the terrain is complex and inclined, and it is difficult to use machinery to operate on the slope. At the same time, manual sowing is difficult and it is difficult to meet the full coverage of grass seed sowing operations.

[0003] After searching, the patent publication number CN114604430A is an automatic seed sowing device for agricultural drones, including a mounting plate, a mounting shell and a seed box are installed at the bottom of the mounting plate, the seed box is located in the mounting shell, and a collection mechanism is arranged on both sides of the mounting shell. A sowing mechanism and a coating mechanism matched with the sowing mechanism are arranged in the mounting shell, and an adhesion mechanism is arranged on both sides of the inner wall of the mounting shell, and the adhesion mechanism is located below the sowing mechanism. In this invention, while the rotating roller rotates, the pakchoi seeds in the seed box fall into the seed groove, and the pakchoi seeds are rotated and sown by using the seed groove and the rolling sleeve opened on the outer wall of the rotating roller, so that the pakchoi seeds can be discharged evenly and the spacing is equal, ensuring that the pakchoi seeds sown and planted in the field later are evenly distributed in the growth spacing, and the pakchoi growth can be used to adjust the rotation speed of the rotating roller according to the flight speed of the agricultural drone to adjust the sowing speed of the pakchoi planting.

[0004] In the process of implementing this solution, it was found that the following problems in the prior art have not been well solved: during seed sowing, the seeds will fall inside the rotating roller. At the same time, the seed grooves on the circumferential outer wall of the rotating roller cannot guarantee that the seeds can fall smoothly, which can easily cause the seeds to get stuck inside the seed grooves and cause blockages. Manual clearing is required, and stable seed sowing cannot be carried out. Therefore, it is urgent to design an automatic seed sowing device for agricultural drones to solve the above problems.

[0009] Furthermore, the sealing assembly includes a fixing frame fixedly connected to the outer wall of one side of the mounting plate, an outer wall of one side of the fixing frame is fixedly connected to an inclined rod, the fixing frame is fixedly connected to a motor through the inclined rod, an output end of the motor is fixedly connected to a first rotating column, one end of the first rotating column is fixedly connected to a sealing cylinder, the sealing cylinder is adapted to the sealing groove, and a through groove is provided on the circumferential outer wall of the sealing cylinder.

[0010] Furthermore, a matching groove is provided on the circumferential outer wall of the sealing cylinder, and equally spaced clamping holes are provided on the bottom inner wall of the matching groove. A water absorbent pad is installed inside the matching groove, and a clamping column is fixedly connected to the bottom outer wall of the water absorbent pad, and the clamping column and the clamping hole are clamped with each other.

[0011] Furthermore, a rotating wheel is fixedly connected to the circumferential outer wall of the first rotating column, a swing rod is fixedly connected to the circumferential outer wall of the rotating wheel, and a protrusion is fixedly connected to the outer wall of one side of the storage hopper.

[0012] Furthermore, the wetting component includes a connecting frame fixedly connected to the outer wall of one side of the top plate, one end of the connecting frame is fixedly connected to a liquid storage tank, one side of the liquid storage tank is plugged with a liquid injection tube, one end of the liquid injection tube is threadedly connected to a sealing cover, nutrient solution is contained in the liquid storage tank, a liquid guide tube is plugged into the bottom of the liquid storage tank, one end of the liquid guide tube is plugged into a wetting cylinder, the circumferential outer wall of the wetting cylinder is provided with a water seepage groove, the inside of the water seepage groove is provided with a permeable membrane, and the circumferential outer wall of the sealing cylinder is in contact with the water seepage groove.

[0013] Furthermore, handles are fixedly connected to the outer wall of the storage hopper, and the handles are provided in two groups, which are distributed on both sides of the storage hopper.

[0015] The inner circumferential wall of the driven wheel is fixedly connected with a second rotating column, the second rotating column is located inside the moistening cylinder, and the outer circumferential wall of the second rotating column is fixedly connected with stirring rods distributed at equal distances.

[0016] After adopting the above structure, the present invention has the following advantages compared with the prior art: In the present invention, by providing a clamping assembly and a sealing assembly, before people need to carry out seed sowing work, they can first clamp the storage hopper filled with seeds in the inside of the clamping slot through the clamping plate, and then start the motor to drive the first rotating column to rotate. During the rotation of the first rotating column, the sealing cylinder located below the storage hopper can be driven to rotate. Since the sealing cylinder and the sealing slot cooperate with each other, when the through groove provided on the circumferential outer wall of the sealing cylinder rotates to the bottom of the cloth plate, the seeds can leak out from the inside to complete the sowing work. At the same time, the through groove is a through type, so there will be no blockage during the sowing process, which ensures that the seeds can fall stably, and the staff can adjust the seed sowing distance by replacing the cloth plate, which meets people's use needs. When the motor starts to drive the first rotating column to rotate, it will also drive the rotating wheel fixed on its outer wall to rotate.

When the swing arm rotates, it will be squeezed with the protrusion, thereby applying a lateral squeezing force to the storage hopper. The outer walls of both sides of the storage hopper are fixedly connected with a connecting seat, and the clamping plate and the connecting seat are rotatably connected. Therefore, when the storage hopper is subjected to a lateral squeezing force, it will swing, thereby playing a role of vibration screening, accelerating the leakage of seeds inside the storage hopper, and avoiding blockage of seeds during automatic sowing.

[0017] In the present invention, through the wetting component, when the motor drives the sealing cylinder to rotate, the circumferential outer wall of the sealing cylinder is provided with a water-absorbing pad, and at the same time, a wetting cylinder fitted with the sealing cylinder is provided on the left side of the sealing cylinder. When the water-absorbing pad rotates to one side of the water seepage groove of the wetting cylinder, the nutrient solution will contact the water-absorbing pad through the permeable membrane. At this time, the water-absorbing pad will be full of nutrient solution. When the water-absorbing pad rotates to the right below the sealing groove, the seeds to be sown will contact it. At this time, the surface of the seeds can adhere to the nutrient solution, so that the survival rate of the sown seeds is higher. When the starting motor drives the first rotating column to rotate to sow seeds, the rotation of the first rotating column can drive the driving wheel to rotate. At the same time, the driving wheel and the driven wheel are connected by a transmission belt. Therefore, the rotation of the driven wheel can drive the second rotating column to rotate. During the rotation of the second rotating column, the stirring rod fixed on the outer wall thereof can be driven to rotate. At the same time, the stirring rod is located inside the wetting cylinder. Therefore, the rotation of the stirring rod can fully stir the nutrient solution to avoid precipitation in the nutrient solution and other conditions that lead to uneven fertilizer efficiency.
