Description

Technical Field

[0001] This utility model relates to the field of agricultural implements technology, specifically to a planting spacing adjustment device for a corn planter. Background Technology

[0002] Corn is an annual monoecious, cross-pollinated plant. Tall and robust, it is an important food and forage crop, and the world's highest-yielding crop. Rich in protein, fat, vitamins, trace elements, and fiber, it has enormous potential for developing highly nutritious and biologically functional foods. To improve corn planting efficiency, corn planting machines are often used to assist in planting. These machines move to place corn seeds into planting holes. However, currently available self-propelled corn planting machines do not easily adjust the planting spacing, and it is difficult to ensure that the spacing is equal after adjustment, which is not conducive to planting different varieties of corn.

[0003] A prior art patent with publication number CN219938914U discloses a solution including a seeding vehicle and a storage cylinder for sowing seeds. The top of the seeding vehicle is provided with a through groove running vertically through it. The middle of the seeding vehicle is provided with a working chamber, which is connected to the through groove. The storage cylinder is installed in the through groove and includes a fixed cylinder located in the middle of the through groove and movable cylinders located on both sides of the fixed cylinder. The movable cylinders are slidably connected to the through groove from left to right. The working chamber is provided with an adjustment component that drives the movable cylinders to slide synchronously outward or inward. This device can adjust the sowing spacing of corn seeds according to the planting distance required for different varieties of corn and keep all spacings equal.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, existing corn planters cannot automatically adjust the spacing between adjacent seed tubes according to different row spacings during planting, which reduces the planting efficiency of corn planters.

[0006] Secondly, when corn planters use the seeding tube for sowing, seeds often get stuck inside the tube, which affects the sowing efficiency.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
