DEVICE FOR CUTTING WATER-ABSORBING SLOTS WITH THEIR SIMULTANEOUS FILLING WITH STRAW Russian patent published in 2021 - IPC A01B13/16 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building and may be used for treatment of soil subjected to water erosion. Device for cutting water-absorbing slots with their simultaneous filling with straw contains a frame with a slot cutter, guides and covering working elements installed on it. Guides are made in the form of rakes, and the covering working element is in the form of freely rotating disc. Between the slot cutter and the guides symmetrically to the longitudinal plane of symmetry of the slot cutter there installed are fixed on the frame by means of a frame with the possibility of height adjustment with the due to adjustment devices and with possibility of rotation relative to perpendicular longitudinal plane of symmetry of slot cutter horizontal axis of rotation two sealing side support rollers. Support surface of rollers is made concave in form of hyperboloid of rotation relative to perpendicular plane of symmetry of slot cutter to horizontal axis of rotation. Adjacent end flat surfaces of the sealing side support rollers located opposite each other are located in continuation of the planes located with them on one side relative to the longitudinal plane of symmetry of the slot cutter of its slot-forming side surfaces.

EFFECT: improved water-absorbing capacity of the slot.
