Description

Technical Field

[0001] The invention relates to the technical field of wheat sowing, in particular to a wheat precision sowing device based on hard soil. Background Art

[0002] Wheat sowing is an important agricultural production activity, which is of great significance to ensuring food security and farmers' livelihoods. In China, wheat is one of the main food crops, widely planted in North China, the Huanghuaihai Plain, and the middle and lower reaches of the Yangtze River. The time, method and technology of wheat sowing have a direct impact on the yield and quality of wheat. In the process of wheat sowing, tilling the soil is a key step, but the difficulty and methods of tilling the soil vary for different types of soil. For soft soil, ordinary tilling equipment can easily till the soil to ensure that the soil is loose, which is conducive to the germination and growth of wheat seeds. However, for hard soil that has been dry for a long time, tilling becomes complicated and difficult. Due to water loss and tight structure of this kind of soil, ordinary tilling equipment will appear to be very strenuous when operating, and may even lead to incomplete or failed tillage. Insufficient tillage will hinder the normal germination of seeds and the growth of seedlings, thereby affecting the success rate of wheat sowing, and then reducing future harvests and agricultural production efficiency. Therefore, we proposed a wheat precision sowing equipment based on hard soil. Summary of the invention
