METHOD OF MANUFACTURING MINI-RAKE Russian patent published in 2023 - IPC A01D7/00 

FIELD: agricultural equipment.

SUBSTANCE: method of manufacturing a mini-rake can be used, for example, on an individual farm. The method for making a mini-rake is to make a handle and fingers with claws curved relative to them from metal wire. Two blanks of the same length are made from spring alloy wire, the ends of the blanks are sharpened, and in each blank, the ends of the same length are bent on both sides at right angles and in the same plane, forming claws, the first blank is bent in half so that the claws are parallel to each other, and then bend the second workpiece in half on a mandrel with a diameter of 10 mm in the same way. Then both the blanks are assembled together so that the claws point in the same direction, and a handle is formed by fixing the blanks with two soft wire bands. Moreover, one of the bandages is placed at a distance of 0.1 times the rake length from the edge of the handle, and the second - at 0.7 times the rake length. Then the fingers with the claws of the outer workpiece are spread to form an angle α=60° between them by moving each of these fingers symmetrically to the axis of symmetry of the rake at an angle of α/2. Then move two fingers with the claws of the inner workpiece apart in a similar way to an angle of α/6.

EFFECT: reliability and ease of use.
