[0002] In agricultural production, corn is an important food and cash crop. The efficiency and quality of its sowing process directly affect its subsequent growth and final yield. Different corn varieties and different planting areas have specific requirements for row spacing. However, the row spacing adjustment mechanism of traditional seeders is complex and the adjustment process is cumbersome. It often requires disassembling multiple parts and recalibrating, which not only consumes a lot of time and manpower, but also makes it difficult to guarantee the adjustment accuracy. In terms of synchronous sowing performance, most existing seeders lack a reliable synchronous transmission mechanism between multiple sowing units. During operation, it is easy to cause inconsistent sowing rhythms of each sowing unit, resulting in uneven sowing and increasing the difficulty of later field management. Therefore, there is an urgent need for a corn seeder that is easy to adjust the spacing. Utility Model Content

[0017] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a connecting frame 1 and a traveling wheel 2, and the traveling wheel 2 is rotatably arranged on both the left and right sides of the connecting frame 1; It also includes: Motor 3 is fixedly installed inside the connecting frame 1. A lead screw 4 is fixedly installed on the output shaft of motor 3, and the lead screw 4 is rotatably installed inside the connecting frame 1 through a bearing. A cam groove plate 5 is rotatably sleeved on the lead screw 4 through a thread. The cam groove plate 5 is slidably installed inside the connecting frame 1 through a slide rail pair. Two guide rods 18 are fixedly installed inside the connecting frame 1, and the guide rods 18 are movably inserted through the cam groove plate 5. The guide rods 18 can provide auxiliary guidance for the up and down movement of the cam groove plate 5, thereby effectively improving the movement stability of the cam groove plate 5. The slider 6, of which there are several, is movably disposed in the groove 7 opened on the front side wall of the connecting frame 1. The guide block 9 is movably disposed in the guide groove 8 opened on the cam groove plate 5 at several equal intervals. The movable frame 10 is fixedly disposed on the guide block 9 and is fixedly disposed on the slider 6. A material conveying shell 11, comprising several shells, is fixedly mounted on several sliders 6. A storage shell 12 is fixedly mounted on each material conveying shell 11. A synchronous sowing mechanism 13 is provided on each material conveying shell 11. A scale line 14 is located on the front side wall of the connecting frame 1 above the slide groove 7, and the scale line 14 is designed to cooperate with the storage shells 12. The scale line 14 allows workers to accurately determine the distance between adjacent storage shells 12, thereby facilitating precise adjustment of the sowing row spacing. A seeding tube 15 is fixedly installed at the bottom of the conveying shell 11, and the seeding tube 15 is located outside the bottom outlet of the conveying shell 11. The seeding tube 15 can provide seeding guidance for the seeds falling from the conveying shell 11, so as to avoid the seeding position being greatly deviated due to wind force or other factors during the seed falling process. A strip opening 16 is opened on the front side wall of the storage shell 12, and a transparent baffle 17 is fixedly installed in the strip opening 16. The staff can observe the amount of seeds stored in the storage shell 12 through the transparent baffle 17. The synchronous seeding mechanism 13 includes: Rotating shaft 13-1, there are several rotating shafts 13-1, which are respectively inserted into several material conveying shells 11 through bearings. A seeding disc 13-2 is fixedly sleeved on the rotating shaft 13-1. Several seeding grooves 13-2-1 are opened on the annular side wall of the seeding disc 13-2 with equal rounded corners. A drive housing 13-3, of which there are several, is fixedly installed on the front side wall of several conveying housings 11. A drive sleeve 13-4 is rotatably installed inside the drive housing 13-3 via a bearing. A first bevel gear 13-5 is fixedly installed on the drive sleeve 13-4. A second bevel gear 13-6 that meshes with the first bevel gear 13-5 is fixedly installed at the front end of the rotating shaft 13-1. Two fixed frames 13-7 are fixedly installed on the left and right sides of the front side wall of the connecting frame 1, respectively. The drive shaft 13-8 is rotatably mounted on the two fixed frames 13-7 through bearings. The drive sleeve 13-4 is movably mounted on the drive shaft 13-8. A second motor 13-9 is fixedly installed on the left fixed frame 13-7. The output shaft of the second motor 13-9 is connected to the drive shaft 13-8. With the cooperation of the synchronous sowing mechanism 13, the synchronous rotation of several rotating shafts 13-1 and the sowing disc 13-2 can be realized to ensure the consistency of the sowing rhythm.

[0018] When using this utility model, the connecting frame 1 is connected to agricultural machinery such as a tractor. Then, the rotation of the walking wheels 2 can be used to move the seeder on the field. The second motor 13-9 is started. The second motor 13-9 drives the drive shaft 13-8 connected to it to rotate. The drive shaft 13-8 drives several drive sleeves 13-4 to rotate synchronously. The drive sleeves 13-4 drive the first bevel gear 13-5 to rotate. The first bevel gear 13-5 drives the rotating shaft 13-1 to rotate through the second bevel gear 13-6. The rotating shaft 13-1 drives the seeding disc 13-2 to rotate. At this time, the seeds in the storage shell 12 will fall into the seeding trough 13-2-1 that has rotated to the top, while the seeds in the seeding trough 13-2-1 that has rotated to the bottom will fall down to the field through the seeding tube 15, thereby realizing sowing. When the sowing spacing needs to be adjusted according to the planting row spacing requirements, motor 3 can be started. Motor 3 drives the lead screw 4 to rotate, adjusting the height of the cam groove plate 5 in the connecting frame 1. The guide block 9 will move in the guide groove 8, so that the guide block 9 drives the moving frame 10 to move horizontally. With the cooperation of the slider 6, the distance between several material conveying shells 11 can be adjusted synchronously, thereby realizing the adjustment of the sowing spacing.

[0019] Compared with the prior art, the beneficial effects of this utility model are: Driven by motor 3, the lead screw 4 rotates, and in conjunction with the linkage structure of cam groove plate 5, guide block 9 and slider 6, the synchronous and equidistant adjustment of several material conveying shells 11 is achieved. No manual disassembly and calibration is required, which greatly simplifies the row spacing adjustment process. At the same time, combined with the scale line 14 on the connecting frame 1, the staff can intuitively grasp the distance between adjacent material storage shells 12, ensuring that the row spacing adjustment is accurately matched to different planting needs, and effectively improving the adaptability of the seeder to diverse planting scenarios. The synchronous sowing mechanism 13, driven by motor 13-9, achieves synchronous rotation of multiple sowing discs 13-2 through the transmission cooperation of drive shaft 13-8, drive sleeve 13-4 and bevel gear. This transmission design ensures that the sowing rhythm of all sowing units is completely consistent, avoiding the problem of uneven sowing caused by asynchronous transmission in traditional sowing machines, ensuring the uniformity of sowing density, and laying the foundation for the uniform growth of corn seedlings. The guide rod 18 provides auxiliary guidance for the movement of the cam groove plate 5, which significantly improves the stability of the cam groove plate 5 during the adjustment process; The seeding tube 15 precisely guides the seed's falling path, effectively avoiding seeding position deviations caused by external factors such as wind.

[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
