[0002] Sowing is an important basic task in agricultural production. The emergence of seeders has greatly improved the efficiency of agricultural production and reduced the intensity of manual labor.

[0003] Currently, common equipment mainly focuses on sowing single crops or with specific row spacings. When dealing with different crop types, such as peanuts, corn, peas, rice and other crops, it is often necessary to replace the equipment or perform cumbersome adjustment operations, resulting in low operation efficiency. Seeders with fixed row spacings cannot meet the requirements of different planting methods and scales. The seed distribution lacks flexibility, and problems such as seed jamming and uneven feeding are likely to occur, which cannot meet the diverse production needs of modern agriculture and greenhouse planting.

[0004] Therefore, it is particularly important to design and manufacture a multi-purpose automatic double-ridge seeder suitable for sowing various crops with uniform and stable feeding for actual sowing processes. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-purpose automatic double-ridge seeder to solve the problem of not being able to meet the requirements of different planting methods and scales as mentioned in the above background art.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A multi-purpose automatic double-ridge seeder includes a frame. The front end of the frame is fixedly connected to a front frame through an adjustment part. Both sides of the front end of the front frame are rotatably connected to mounting frames. A set of sowing wheels are rotatably installed at the front ends of the two mounting frames through fixing frames. A sowing mechanism for guiding seeds to be buried in the ground at equal intervals by gravity is arranged between the mounting frame and the sowing wheels. Two soil covering wheels are rotatably installed on both sides of the lower end of the front frame behind the sowing wheels. The rear end of the front frame is fixedly connected to a rear frame. Two rear wheel motors are symmetrically installed at both ends of the rear frame, and rear wheels are installed at the outer ends of the rear wheel motors.

[0007] As a further description of the above technical solution: The sowing mechanism includes a sowing box fixed above one side far from the fixing frame at the front end of the mounting frame, a plurality of openers fixedly arranged in an annular array between the outer circumference of the sowing wheel and the outer end of the fixing frame, and a seed distribution wheel rotatably installed at the front end of the mounting frame for communicating the sowing box and the sowing wheels.

[0008] As a further description of the above technical solution: The inside of the sowing wheel is a hollow structure, and the sowing wheel is interconnected with a plurality of openers.

[0009] As a further description of the above technical solution: The cross-sections of the multiple mouth openers are triangular structures, and after the multiple mouth openers are rotated and inserted into the ground, the openings are distributed backward.

[0010] As a further description of the above technical solution: The seed distribution wheel is linked to the axle of the seeding wheel through a gear set.

[0011] As a further description of the above technical solution: At one end of the seed distribution wheel close to the seeding box, a plurality of blanking holes are equidistantly arranged for the seeds in the seeding box to enter the interior of the seed distribution wheel under the action of gravity.

[0012] As a further description of the above technical solution: The position adjustment part includes multiple groups of ridge distance adjustment holes 12 equidistantly arranged along the length direction at the front end of the frame and fastening bolts fixedly screwed between the front frame 11, the frame 13 and the ridge distance adjustment holes 12.

[0013] As a further description of the above technical solution: The soil covering wheel is aligned with the seeding wheel in the traveling direction.

[0014] As a further description of the above technical solution: In the middle of the upper end of the rear frame, a remote control system is installed between two rear wheels.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4, the present invention provides a technical solution: a multi-purpose automatic double-ridge seeder, including a frame 13. The front end of the frame 13 is fixedly connected to a front frame 11 through an adjustment part. On both sides of the front end of the front frame 11, mounting frames 5 are rotatably connected. At the front ends of the two mounting frames 5, a set of seeding wheels 10 are rotatably installed through fixing frames 8. A seeding mechanism for guiding seeds to be buried underground at equal intervals by gravity is arranged between the mounting frame 5 and the seeding wheel 10. On both sides of the lower end of the front frame 11, behind the seeding wheels 10, soil covering wheels 4 are rotatably installed. The rear end of the front frame 11 is fixedly connected to a rear frame 3. At both ends of the rear frame 3, two rear wheel motors 14 are symmetrically installed. At the outer ends of the rear wheel motors 14, rear wheels 1 are installed.

[0022] Specifically, as Figures 1 - 4 shown, the seeding mechanism includes a seeding box 6 fixed above one side of the front end of the mounting frame 5 and far from the fixing frame 8, a plurality of openers 7 fixedly arranged in an annular array between the outer circumference of the seeding wheel 10 and the outer end of the fixing frame 8, and a seed distribution wheel 9 rotatably installed at the front end of the mounting frame 5 and used for communicating the seeding box 6 and the seeding wheel 10.

[0023] Among them, the inside of the seeding wheel 10 is a hollow structure, and the seeding wheel 10 is interconnected with the plurality of openers 7. After the seeds enter the seeding wheel 10 through the seed distribution wheel 9, they can fall into the opener 7 at the bottom of the seeding wheel 10 under the action of gravity, and then the seeds are buried in the soil.

[0024] In addition, the cross-sections of the plurality of openers 7 are triangular structures, and the openings of the plurality of openers 7 are distributed backward after rotating and inserting into the ground. After rotating and opening the soil, it does not affect the seeds in the seeding wheel 10 to fall into the soil through the openers 7 by rotation.

[0025] Specifically, as Figures 1 - 4 shown, the seed distribution wheel 9 is linked to the axle of the seeding wheel 10 through a gear set. At the same time, a plurality of material dropping holes for the seeds in the seeding box 6 to enter the inside of the seed distribution wheel 9 under the action of gravity are equidistantly arranged at one end of the seed distribution wheel 9 close to the seeding box 6. The seeds in the seeding box 6 can stably enter the seed distribution wheel 9 through the rotating material dropping holes on the seed distribution wheel 9, and then enter the cavity inside the seeding wheel 10. Under the action of gravity and rotational force, they enter the soil downward through the opening part of the opener 7.

[0026] Specifically, as Figure 1As shown in the figure, the position adjustment part includes multiple groups of ridge distance adjustment holes 12 evenly arranged at the front end of the frame 13 along the length direction and fastening bolts installed by threaded fixed-point screwing between the front frame 11, the frame 13 and the ridge distance adjustment holes 12. When it is necessary to adjust the overall distance of the front frame 11, the fastening bolts can be pre-unscrewed from the ridge distance adjustment holes 12 on the frame 13 using tools, and then the front frame 11 can be adjusted as a whole in the length direction of the frame 13 according to the actual seeding use requirements. Finally, after using tools to screw the fastening bolts into the front frame 11, the frame 13 and the ridge distance adjustment holes 12 at the specified position, the adjustment operation of the distance between the two seeding wheels 10 and the seeding box 6 is completed.

[0027] Specifically, as Figures 1 - 4 shown in the figure, the soil covering wheel 4 is aligned with the seeding wheel 10 in the traveling direction, and can compact the seeds buried in the soil through the opener 7 to prevent the seeds from being directly exposed outside the soil.

[0028] Specifically, as Figures 1 - 4 shown in the figure, a remote control system 2 is installed in the middle of the upper end of the rear frame 3 between the two rear wheels 1. The input end of the remote control system 2 can establish a wireless signal connection with the output end of a handheld intelligent device or a remote control. The output end of the remote control system 2 is electrically connected to the rear wheel motor 14. The remote control system 2 can receive wireless control signals in real time, and then can control and adjust the forward rotation, reverse rotation and speed of the rear wheel motor 14, so as to realize the remote control walking operation of the seeding machine.

[0029] Specifically, as Figures 1 - 4 shown in the figure, when handling and turning, the two seeding wheels 10 are installed at the mounting frame 5. Since the mounting frame 5 is rotatably connected to the front frame 11, the seeding wheels 10 can be automatically lifted by the external drive system of the seeding machine, and only rely on the rear rear wheels 1 and the soil covering wheels 4 to realize the forward function, reduce the wear on the opener 7, adapt to more complex terrains, reduce noise and unnecessary air and soil pollution Working principle: When in use, the seeder first needs to reach the designated seeding area. The user pre-establishes a wireless signal connection between the handheld intelligent device or remote control device and the remote control system 2, and then uses the help of the LiDAR or vision sensor to drive the seeder to the corresponding seeding position. After the seeding machine reaches the target position, the prepared target seeds need to be put into the seeding box 6 to ensure that the long-term feeding work is reduced during seeding. The seeder advances along a predetermined trajectory through the remote control system 2. The seeding wheel 10 digs pits and sows seeds through the opener 7 to ensure that each seed lands on the ground and is evenly distributed. After the seeding wheel 10 finishes digging pits and filling seeds, the soil covering wheel 4 will backfill and compact the soil to ensure that the seeds are not exposed. During handling and turning, the two seeding wheels 10 are installed at the mounting frame 5. Since the mounting frame 5 is rotatably connected to the front frame 11, the seeding wheels 10 can be automatically lifted by the external drive system of the seeder, and only the rear wheels 1 and the soil covering wheel 4 are relied on to realize the forward function.

[0030] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
