SCREW AUGER FOR PLANTING SEEDLINGS ON FILM COATING Russian patent published in 2024 - IPC A01C5/00 E21B10/44 

FIELD: agriculture.

SUBSTANCE: drill contains a supporting pipe, on the lower part of which there is a guide rod of round cross-section and a double-threaded auger, with sections of replaceable trapezoidal blades for technical knives mounted on it. A rotation handle is attached to the upper end of the support pipe. To cut the roots along the walls of the well, a hole saw is used, the internal diameter of which is equal to the external diameter of the auger. The serrated edge of the saw is installed below the lower end of the support pipe. The saw is attached to the drill where it contacts the bottom of the outer edges of the auger spirals. To prevent damage to the film by saw teeth, a removable protective strip made of thin sheet material is used. Thin rectangular neodymium magnets are attached to the ends of the strip, which, when closing the strip into a ring, partially overlap and provide the necessary force for pressing the strip to the ring.

EFFECT: invention improves conditions and reduces the time of drilling landing wells.
