The results of laboratory studies of the automatic seeding depth control system
When sowing crops, high demands are placed on the quality of the process. Including the observance of the depth of sowing. Existing depth tracking systems do not allow adjusting the coulter deviations during the movement of the unit, which negatively affects the uniformity of sowing and ultimately leads to a decrease in yield. This paper presents the results of laboratory studies of the sowing depth control system for disc seeders using a stiffness regulator made on the basis of a flexible tubular element. During the experiment, the hydraulic pressure supplied to the cavity of the stiffness regulator, the movement of the coulter under the action of the force of the regulator, and the time of the complete movement process were recorded. It was found that with increasing pressure, the movement of the coulter in the vertical plane has a dependence close to linear. The maximum coulter travel when applying pressure within the stiffness of the stiffener material is more than 50mm. When simulating the situation when the coulter goes beyond the set depth range, the process of returning it to its original state does not exceed 1.8 s. The results obtained will allow you to configure the system in its practical application in the sowing process.
