ADAPTIVE DISC PLOUGHSHARE Russian patent published in 2024 - IPC A01C7/20 A01C5/06 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to working elements of agricultural machines for tillage and sowing of grain crops. Adaptive disc ploughshare includes a spherical disc fixed on a hub with a bearing assembly and an axis, and connected to a post, which is attached to the ploughshare bar, mechanisms for adjustment of angle of attack and angle of inclination of spherical disk, hydraulic cylinder for adjustment of spherical disk stroke depth. Mechanism for adjusting the angle of inclination of the spherical disc in the vertical plane includes a head fixed on a post and a bushing with a ball installed in it, having a through cylindrical hole for installation of an axis on which there is a collar, and a stop with a lug is fixed by means of a retainer. Post head is installed between the collar and the stop with an lug, and between the lugs of the stop and the post there is a lower hydraulic cylinder. Mechanism for adjusting the angle of attack of the spherical disc includes a leash, a plank and an upper hydraulic cylinder, the rod of which is pivotally connected to a plank located parallel to the ploughshare bar, to which one end of the leash is also hinged. Other end of the leash has a splined connection with the post. Hydraulic cylinders of mechanisms for adjusting the angle of inclination and angle of attack of the spherical disc, as well as the hydraulic cylinder for adjusting the spherical disk stroke depth are connected through electrohydraulic slide valves to a control unit which is connected to a soil moisture sensor.

EFFECT: invention will make it possible to improve the quality of soil treatment and sowing of seeds of grain crops by improving the process of forming a sowing furrow, increase crop capacity and reduce traction resistance during operation of the adaptive ploughshare, simultaneously perform soil treatment and sowing operations with reduction of time spent on the adjustment process.
