[0038] Embodiment 1

[0039] like Figure 1-Figure 6 As shown, the utility model provides an unmanned agricultural seeder, comprising an unmanned tractor and a trailer frame 1 fixedly connected thereto; a feeding assembly for sowing and feeding; and a soil turning assembly for turning over the soil layer.

[0040] By fixing a tilling shovel 101 on the trailer 1, connecting a soil leveling roller 102 to the trailer 1 through a chain, and arranging the soil leveling roller 102 behind the tilling shovel 101, the tilling shovel 101 can break the soil layer, and then the feeding assembly is used for sowing. After the sowing is completed, the soil leveling roller 102 flattens the soil layer, so as to make the sowing effect better. A tilling shovel 101 and a soil leveling roller 102 are grouped as a group, and multiple groups are arranged in a linear array at equal intervals on the trailer 1, so that tilling and sowing can be carried out in multiple places at the same time, thereby improving the working efficiency of the device by increasing the number of operations each time.

[0041] By symmetrically arranging two adjustment components on both sides of the trailer 1, rotating one end of the connecting rod 2 on one side of the trailer 1, and rotating the connecting wheel 201 on the other end of the connecting rod 2, the straight-line distance between the wheel 201 and the trailer 1 can be adjusted by changing the angle between the connecting rod 2 and the trailer 1, and by installing a connecting frame 202 on the other end of the connecting rod 2, rotating the connecting screw rod sleeve 203 on the connecting frame 202, threading the screw rod 206 in the screw rod sleeve 203, and fixing the mounting frame 205 on one side of the trailer 1, and rotating the screw rod 206 in the mounting frame 205, the screw rod sleeve 203 can be moved away from the mounting frame 205 by rotating the screw rod 206, thereby driving the wheel 201 to move in a continuous manner. The rotating connection between the rod 2 and the trailer 1 is the center of the circle and performs circular motion within a certain range, so that the straight-line distance between the wheel 201 and the trailer 1 can be freely adjusted, so that the soil-turning component can selectively contact the ground, and the thickness of the soil layer turned by the soil-turning component when turning the soil can be controlled to adapt to the planting depth of different seeds and land, and the soil-turning component will not contact the ground during transportation, thereby improving the portability of the device. By rotating one end of the rotating block 204 on the connecting frame 202 and rotatably connecting the other end of the rotating block 204 to the screw sleeve 203, the rotatable range of the wheel 201 performing circular motion with the rotating connection between the connecting rod 2 and the trailer 1 as the center is expanded.

[0042] Embodiment 2

[0043] Based on the first embodiment, specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the unloading assembly includes a top plate 4, which is arranged above the trailer 1, and the trailer 1 and the top plate 4 are connected by a column.

[0044] By arranging a collecting box 401 on the top surface of the top plate 4, opening a connecting groove 402 connected to the collecting box 401 on the bottom surface of the top plate 4, fixing the first sprocket 3 on the wheel 201, rotatably connecting the second sprocket 302 on the trailer 1, setting the first chain 301 between the first sprocket 3 and the third sprocket 303, fixing the second sprocket 302 on one side of the third sprocket 303, rotatably connecting the fourth sprocket 304 on the mounting frame 205, setting the second chain 305 between the second sprocket 302 and the fourth sprocket 304, fixing the transmission shaft 306 on the fourth sprocket 304, and setting a seed separation plate 307 on the transmission shaft 306, so that when the wheel 201 rotates, the first sprocket 3 The second sprocket 302 drives the third sprocket 303 to rotate synchronously, and then the power is transmitted to the fourth sprocket 304 through the second chain 305, thereby driving the seeding plate 307 to rotate and sprinkle the seeds in the collection box 401 in batches, so as to realize automatic sowing. By making the diameter of the first sprocket 3 smaller than the second sprocket 302, and the diameter of the third sprocket 303 smaller than the fourth sprocket 304, the transmission ratio between the first sprocket 3 and the fourth sprocket 304 is reduced, so that the wheel 201 rotates one circle and the seeding plate 307 moves forward one grid, so as to realize quantitative sowing, and by setting a resistance on the outside of the seeding plate 307 The retaining groove 308 is provided with a through groove 309 on the retaining groove 308, and the other end of the seeding pipe 501 is arranged behind the tilling shovel 101, so that the seeds on the seeding plate 307 will not be directly scattered, but can only be scattered from the through groove 309 when the seeds pass through the through groove 309, thereby further limiting the number of seeds scattered, and by arranging a collecting chamber 5 on the outer side of the through groove 309, and fixing one end of the seeding pipe 501 on the bottom surface of the collecting chamber 5, the seeds will enter the collecting chamber 5 when they are scattered from the through groove 309, and then be transported to the bottom of the trailer 1 through the seeding pipe 501 for sowing, thereby preventing the seeds from being scattered at a high place and then being blown by the natural wind, causing the sowing position to be offset. By setting a limiting hole 103 on the trailer 1, the other end of the seeding pipe 501 is passed through the limiting hole 103, so that the other end of the seeding pipe 501 can be limited by the limiting hole 103, thereby preventing the other end of the seeding pipe 501 from shaking with the bumps encountered when the trailer 1 moves forward, causing the sowing position to shift. By setting a plurality of feeding components, which are arranged in a linear array with equal intervals, and the number of the feeding components is the same as the number of the tilling shovel 101 and the soil leveling roller 102, the feeding components correspond to the tilling shovel 101 and the soil leveling roller 102, so that the sowing speed of the device is faster, and different plant seeds can be set in the top plates 4 of different feeding components, so as to achieve classified sowing.

[0045] Working principle:

[0046] To adapt to the planting depth of different seeds.

[0047] In the utility model, an adjusting component is provided.

[0048] The screw rod 206 can be rotated to move the screw rod sleeve 203 away from the mounting frame 205, thereby driving the wheel 201 to make a circular motion within a certain range with the rotating connection between the connecting rod 2 and the trailer 1 as the center, so that the straight-line distance between the wheel 201 and the trailer 1 can be freely adjusted, and the thickness of the soil layer turned by the soil turning component during soil turning can be controlled to adapt to different seeds and planting depths of land, and the soil turning component will not contact the ground during transportation, thereby improving the portability of the device.

[0049] In order to achieve automatic sowing without increasing the power source.

[0050] In the utility model, an adjusting component and a sowing component are provided.

[0051] When the wheel 201 rotates, the first sprocket 3 will rotate synchronously, and then the power will be transmitted to the second sprocket 302 through the first chain 301. The second sprocket 302 will drive the third sprocket 303 to rotate synchronously, and the power will be transmitted to the fourth sprocket 304 again through the second chain 305, thereby driving the seed separation plate 307 to rotate, and reducing the transmission ratio between the wheel 201 and the first sprocket 3, and allowing the seeds on the seed separation plate 307 to be sprinkled only through the through groove 309, further limiting the number of seeds to be sprinkled, so that the seeds in the collection box 401 can be sprinkled in batches and quantitatively, thereby realizing automatic sowing without increasing the power source.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
