Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a sowing device for rapeseed cultivation. Background Technology

[0002] Rapeseed, also known as oilseed rape or bitter vegetable, is a plant belonging to the Brassicaceae family and the Brassica genus. It originated in my country and has dark green stems that resemble those of cabbage. It is a variety of cabbage in the Brassicaceae family. Its flowers are yellow. In agronomy, the term rapeseed refers to several species of plants whose seeds contain oil. It is mainly distributed in Anhui, Henan, and Sichuan provinces. Rapeseed is rich in nutrients, especially vitamin C. It generally grows in relatively humid climates, such as southern China. Rapeseed has many uses. For example, the rapeseed flowers can be eaten before they bloom. When the rapeseed flowers are in full bloom, they are a beautiful sight. After the flowers wither, the rapeseed can be pressed for oil.

[0003] Existing rapeseed cultivation seeding devices cannot adjust the seeding rate according to actual conditions. When the seeding rate is too high, the rapeseed seedlings need to be separated manually, which is time-consuming and labor-intensive. Planting furrows need to be dug during sowing. When the spacing of the planting furrows is inconsistent with the position of the seeding port of the existing device, the seeds will fall outside the planting furrows, affecting the sowing effect. To address the above problems, a rapeseed cultivation seeding device is needed. Utility Model Content
