Abstract

The invention discloses a method and device for controlling the sowing depth of a no-tillage seeder, which is arranged on a no-tillage seeder. The sowing depth control device of the no-tillage seeder includes: a master control system; a detection system, including a ditching depth detection A unit, a lower pressure sensor, a ballast pressure sensor and a data collector; and a regulating system, including a hydraulic controller, a hydraulic valve group, a pressure oil cylinder and a pressure oil cylinder. The invention can precisely regulate the sowing depth.

Description

technical field [0001] The invention relates to an online measurement and control device and method for a seeder, in particular to a method and a device for controlling the sowing depth of a no-tillage seeder. Background technique [0002] Precision seeding technology has become an important feature of modern agricultural production, and it is also one of the important technologies for increasing agricultural production and harvest and reducing food production costs. The sowing depth control technology of the no-tillage seeder is an important link in the precision sowing technology. Maintaining a suitable and consistent sowing depth and pressure to ensure good contact between the seeds and the soil will increase the capillary action of the soil on the seed groove, so that the seeds It is easy to absorb water from the soil, which is good for seed germination. At present, on corn seeders, mechanical springs are generally used in conjunction with parallel four-bar monomer prof...
