ROBOTIC DEVICE FOR APPLICATION OF HERBICIDES INTO UNDERTREE STRIPS OF GARDEN Russian patent published in 2020 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to robotic devices for application of herbicides to near-end strip of intensive type garden. Distinctive feature of the solution is that the inlets of at least each of the two solenoid valves 75 and 80, 77 and 78, 76 and 79 are connected by hydraulic lines with outlets of at least one dispenser 71, 72, 73, and outlets of at least two solenoid valves 76, 79 and four solenoid valves 75, 80 and 77, 78 are connected by hydraulic lines with internal headers 22, 23, moving units 42, 43, wherein external headers, in turn, are connected to fixed units 46, 47, 48, 49, and on front ledges 17, 18 and driven 19, 20 frame elements of each working member 8 and 9 are movable rods 34, 35, 36, 37, each of which is connected by one end to the hydraulic cylinder rod 30, 31, 32, 33, by the other end - to the movable blocks bodies 42, 43, 44, 45, respectively, forming, at conjugation with fixed units 46, 47, 48, 49 self-locking and self-connecting shaft-bush rigid fixed connection of two parts, at least, one of frontal elements 17, 18, 19, 20 of working members frames, at that distance between axes of drive 17, 18 and driven elements 19, 20 of frontal sides of frame of each working element is not less than three maximum diameters of tree boles in near-bore bands, and under each front driving and driven frame element of each working member there are gripping-copying deflectors 50, 51, 52, 53, axes of which coincide with axes of row of trees, and contain two symmetrical elements, ends of which are connected by springs to frontal frame members of working members 8 and 9, wherein in the projection of the cross-section of capturing-deflector deflectors 50, 51, 52, 53 on the horizontal plane they have a conoidal profile, oriented by the diffuser part in the direction of movement of the device, wherein the smallest linear dimension z of the input portion of each conoidal profile is greater than the sum of the maximum limit diameter of the tree bend, maximum limit size of deviations of centers of tree trunks in a row and value of maximum permissible limit deviation of axis of symmetry of power facility 1 with robot device from axis of symmetry of space between rows.

EFFECT: creation of a robotic device for application of herbicides into the near-berms of garden plantations, which provides for higher quality of treatment of near-bore strips with herbicides, higher efficiency of technological process.
