Abstract

The invention discloses a method and device for controlling seeding depth of a no-tillage seeder. The device is arranged on the no-tillage seeder. The device for controlling seeding depth of the no-tillage seeder comprises a main control system, a detection system and a regulating system, wherein the detection system comprises a furrowing depth detecting unit, a pressing force sensor, a suppressing force sensor and a data acquisition unit; and the regulating system comprises a hydraulic controller, a hydraulic valve group, a pressing oil cylinder and a suppressing oil cylinder. The method anddevice for controlling seeding depth of the no-tillage seeder disclosed by the invention can accurately adjust and control the seeding 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...
