Technical Field

[0001] The utility model relates to the technical field of agricultural sowing, in particular to a light finger clip precision seeder. Background Technique

[0002] Planting industry is one of the main components of agriculture. It is a social production department that utilizes the life functions of plants and obtains food, non-staple foods, feeds, and industrial raw materials through artificial cultivation, including the cultivation of various crops, forest trees, fruit trees, medicinal and ornamental plants, etc. There are food crops, cash crops, vegetable crops, green manure crops, feed crops, forages, flowers and other horticultural crops. During the planting process, sowing equipment is needed to plant seeds in the fields.

[0003] When the current sowing equipment is in use, a furrow opener is first used to open a furrow in the soil, then the seeds naturally fall into the opened furrow, and finally the furrow is covered with soil. However, there are the following drawbacks in this method: 1. The dropped seeds are too dense (and may even fall on the straw or leaves in the field), with different depths, affecting the growth and nutrient uptake of the later crops; 2. The soil under the seeds at the bottom of the furrow is too hard, which is not conducive to root growth. Content of the Utility Model

[0004] The purpose of the utility model is to provide a light finger clip precision seeder to solve the above problems, as described in detail below.
