METHOD OF SHRIMP CATCHING DEVICES MANUFACTURING Russian patent published in 2018 - IPC A01K80/00 

FIELD: catching device.

SUBSTANCE: method includes tightening a rigid frame by a net consisting of rings of different diameters connected by stiffeners forming the windows and supplying the device with inlet holes. Net is taken in the form of a rectangle having a width equal to the perimeter of the lower ring in the tension, and the length of the net in the landing is equal to the length of the stiffener of the frame plus the length of the radius of the lower ring and plus the length of the radius of the upper ring. Net fabric is sewn along the length, with the formation of a cylindrical net cloth, and fixed on a rigid frame. Cylindrical net is fixed on the lower ring, while leaving the lower edge of the cylindrical net free at a distance from the lower ring equal to the radius of the lower ring. Then, attach the cylindrical net to the upper ring, leaving the upper edge of the cylindrical netting free at a distance equal to the radius of the upper ring. Lower and upper rings are lined with a rope having a diameter greater than the diameter of the filament of the net web not less than three times. From the slack of the net formed in the region of at least two upper parts of the opposite openings between the stiffeners, pull the netting to the center of the rigid frame with double rubber bands at a distance of 10–20 cm from each other, forming the entrance estuary. Inlet holes are placed at the points of attachment of the entrance mouths, making slots in the net.

EFFECT: invention makes it possible to simplify the production of gears, which increase the efficiency of fishing.
