[0002] Corn is one of the most widely grown food crops worldwide, and its yield and quality have a significant impact on agricultural economic development. Corn planting requires the use of a seed drill to ensure even seed distribution and adequate growing space. However, existing corn seed drills have limitations when it comes to adjusting row spacing.

[0003] Traditional corn planters are typically designed with fixed row spacing. This means the spacing between each row of corn seeds is pre-set during sowing, preventing flexible adjustment based on the specific needs of individual fields. In some plots, fixed row spacing can lead to excessively high or low planting densities. Excessively high planting densities can lead to intense competition between corn plants, limiting growth and impacting yield and quality. Excessively low planting densities, on the other hand, underutilize land resources, similarly impacting yield. Therefore, a corn seed planter with adjustable row spacing has been proposed to address these issues. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The present invention provides an embodiment of a corn seed planter with adjustable row spacing, comprising a support 1, with a runner 2 rotatably connected to the outside of the support 1. As the device moves, the runner 2 rotates synchronously. A feeding assembly is mounted on the top of the support 1 for feeding corn seeds in a fixed quantity. The feeding assembly comprises a seed box 3 fixedly connected to the top of the support 1, and a rotating rod 18 rotatably connected to the inside of the seed box 3. The rotating rod 18 is used to store corn seeds. Multiple feed troughs 19 are provided on the outside of the rotating rod 18, and a feeding nozzle 20 is fixedly connected to the outside of the rotating rod 18. A plug plate 21 is inserted in the middle of the feeding nozzle 20, and the plug plate 21 can be used to block the feeding nozzle 20 to adjust the row spacing according to the sowing time. Pulleys 22 are fixedly connected to the outer side of the rotating rod 18 and the inner side of the rotating wheel 2. A synchronous belt 23 is provided on the outer periphery of the two pulleys 22. When the rotating wheel 2 rotates, the bottom pulley 22 can be driven to rotate, and then the top pulley 22 can be driven to rotate under the transmission of the synchronous belt 23, thereby driving the rotating rod 18 to rotate synchronously, and the distributing trough 19 can be made to move in a synchronous circular motion. As a result, the seeds inside the seed box 3 also fall into the distributing trough 19, and then are transported to the position of the discharge nozzle 20 through the rotation of the rotating rod 18 for discharge.

[0032] Reference Figure 2-Figure 3 The rear side of the bracket 1 is fixedly connected to a mounting rod 6. Multiple slots 24 are defined on the outside of the mounting rod 6. A housing 7 is slidably connected to the outer periphery of the mounting rod 6. Inside the housing 7, a movable rod 12 is slidably connected. A plug 13 is fixedly connected to the top of the movable rod 12 and engages with the slot 24. To adjust the position of the housing 7, simply press the movable rod 12 downward to disengage the plug 13 from the middle of the slot 24. This allows the housing 7 to freely move around the outer periphery of the mounting rod 6. A spring 15 is also fixedly connected to the inside of the housing 7. The other end of the spring 15 is fixedly connected to the bottom of the movable rod 12. The spring 15 pushes the movable rod 12 upward, preventing the plug 13 from falling downward in its initial position. A feed tube 8 is fixedly connected to the outside of the housing 7. The diameter of the top opening of the feed tube 8 is larger than the bottom opening of the feed tube 8 to better receive the corn seeds. Seeds that fall from the feed nozzle 20 fall through the top opening of the feed tube 8 and are then conducted through the feed tube 8 to the ground.

[0033] Reference Figure 3The outer side of the rotating wheel 2 is rotatably connected to a rotating rod 4, and a plurality of positioning rods 5 are fixedly connected to the outer side of the rotating rod 4. The outer side of the housing 7 is fixedly connected to a support frame 9. The other end of the support frame 9 is rotatably connected to a rotating ring 10. The rotating ring 10 and the positioning rod 5 are engaged. The outer side of the rotating ring 10 is fixedly connected to a tiller 11. When the rotating rod 4 rotates, it can drive the positioning rod 5 to rotate. At this time, the rotating ring 10 can also rotate, thereby causing the tiller 11 to rotate to dig a hole in the ground, thereby facilitating subsequent sowing. The outer side of the rotating rod 4 is fixedly connected to a transmission assembly for driving the rotating rod 4 to rotate. The transmission assembly includes a gear 2 17. The gear 2 17 is fixedly connected to the end of the rotating rod 4. The inner side of the rotating wheel 2 is fixedly connected to a gear 16. The gear 16 and the gear 2 17 are meshed. When the rotating wheel 2 rotates, the gear 16 can be driven to rotate, and then the gear 2 17 can be driven to rotate synchronously, thereby causing the rotating rod 4 to rotate. At the same time, the rotating rod 4 rotates in the opposite direction to the rotating wheel 2, so as to better perform the digging operation.

[0034] Reference Figure 1-Figure 3 A fixing rod 14 is fixedly connected to the top of the housing 7. The fixing rod 14 is engaged with the slot 24. By engaging the fixing rod 14 with the slot 24 opened at the top of the mounting rod 6, the force on the insertion rod 13 can be reduced, thereby ensuring stable installation. The rotating ring 10 is slidably connected to the outside of the positioning rod 5 and is used to synchronously adjust the position of the tiller 11. The inner diameter of the bottom of the feed pipe 8 is adapted to the width of the tiller 11 to facilitate the entry of seeds into the pit.

[0035] Working principle: When in use, put the corn seeds to be planted into the seed box 3, then place the device on the ground to be sown, connect the bracket 1 with other external traction equipment, and move the traction equipment to drive the wheel 2 to rotate. At this time, the wheel 2 drives the gear 1 16 to rotate, and drives the rotating rod 4 to rotate through the transmission of the gear 2 17. At this time, the positioning of the positioning rod 5 can make the rotating ring 10 rotate. At this time, the soil-turning hoe 11 can be rotated, and the direction of rotation is opposite to that of the wheel 2. When the device is moving, the ground can be dug to facilitate subsequent sowing operations.

[0036] When the runner 2 rotates, the rotating rod 18 can be rotated by the drive of the pulley 22 and the synchronous belt 23, so that the distribution trough 19 can make synchronous circular motion. When the distribution trough 19 rotates to the upper side, the seeds inside the seed box 3 can enter the distribution trough 19, and then the rotating rod 18 continues to rotate to transport the seeds to the position of the discharge nozzle 20, and fall downward to the top of the discharge pipe 8, and then fall into the dug pit through the discharge pipe 8, thereby completing the planting;

[0037] When the planting spacing needs to be adjusted, the movable rod 12 can be pressed downward to move the insertion rod 13 and disengage from the notch on the outside of the shell 7. At this time, the shell 7 can be moved outside the mounting rod 6. After adjusting to the appropriate position, the fixed rod 14 is engaged with the upper slot 24, and then the insertion rod 13 is aligned with the lower slot 24. The movable rod 12 is released, and the insertion rod 13 can be pushed into the inside of the slot 24 under the action of the spring 15, thereby completing the adjustment of the position of the shell 7. While adjusting the position of the shell 7, the rotating ring 10 and the tillage hoe 11 can be driven synchronously, thereby adjusting the digging and sowing operations in one step, which is simpler to operate.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
