Description

Technical Field

[0001] The invention relates to the technical field of agricultural sowing machinery, and in particular to a beet sowing method and device. Background Art

[0002] Sugar beet is an important economic crop, and its cultivation requires efficient and precise sowing devices to ensure planting quality and yield. Traditional sugar beet sowing methods have many problems, such as uneven sowing, difficulty in accurately controlling sowing depth and spacing, and poor adaptability under different terrain and soil conditions.

[0003] For example, a Chinese utility model patent with a publication number of CN212519942U discloses a sub-film seeding device for beet planting, which includes a fixed plate, a first roller, a second roller, a first motor, a feed roller, a leveling shovel and a swing adjustment mechanism. A first roller is provided at the front end of the bottom of the fixed plate, and the swing adjustment mechanism is installed and fixed at the front end of the top of the fixed plate. The swing adjustment mechanism includes a cross plate, a rotating block, a receiving plate, a shovel head, a swing rod and a rotating mechanism. The cross plate is rotatably connected to the left front end of the fixed frame through the rotating block, the receiving plate is locked and fixed to the right end of the cross plate by screws, the receiving plate is fixedly connected to the upper rear end of the shovel head, one end of the swing rod is rotatably connected to the left side of the front end of the cross plate through a hinge shaft, and the other end of the swing rod is rotatably matched with the output end of the rotating mechanism.

[0004] The above solution has the following shortcomings in actual use:

[0005] This solution adopts a swing adjustment mechanism set on the upper end of the fixed plate. The swing of the swing rod drives the horizontal plate to rotate on the upper end of the fixed frame through the rotating block, so that the horizontal plate drives the shovel head to change its height through the receiving plate. However, in actual use, since beet seeds include naked seeds and polished pellet seeds, the two types of beet seeds have different sowing quantities and methods. The above structure lacks flexible adjustment of sowing parameters and components for different types of beet seeds, resulting in low sowing efficiency and serious seed waste, which affects the growth of beets and the final harvest.
