MODULE FOR LAYING MULCHING FILM Russian patent published in 2024 - IPC A01B13/02 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building and can be used for laying irrigation pipeline and mulching film both with simultaneous making of holes for planting material, and without holes. Module for laying mulching film contains successively arranged on frame shovelling elements, levelling board, device for laying irrigation line, film spreading device, pressing wheels, levelling elements and perforator. Additionally, it comprises base with lugs, rockers and linear drive with articulated joints. Perforator is formed by two cylindrical drums with hubs installed on a hexagonal shaft with bearing supports and moving along the shaft by means of a servo drive and a lever mechanism. Lever mechanism is presented in the form of three pivotally connected levers sequentially arranged one after another. Lifting of cylindrical drums is performed from linear drive pivotally connected to lever rigidly fixed on hexagonal shaft on one side. Spring-loaded perforating elements are extended by means of a cam mechanism from a stepper motor and can provide perforation with different pitch. Turn angle sensors are mounted on hubs.

EFFECT: possibility of automatic change of film perforation pattern by displacement of perforator drums hubs along guide shaft in axial direction and change of number of active perforating elements.
