Description

Изобретение относитс к рыболовству , в частности к ледобуру, используемому дл образовани скважин во льду водоемов, предпочтительно дл образовани лунок при подледном лове рыбы.The invention relates to fishing, in particular to ice drill, used for the formation of wells in the ice of reservoirs, preferably for the formation of holes during ice-fishing.

Наиболее близким к предлагаемому вл етс ледобур, содержащий режущую головку, выполненную в виде сферического пустотелого корпуса с резцами и окнами, и приспособление дл удалени лед ной крошки 1.The closest to the present invention is an ice drill, containing a cutting head made in the form of a spherical hollow body with incisors and windows, and a device for removing ice chips 1.

Однако известный ледобур не обеспечивает полной очистки лунок от лед ной крошки при его извлечении.However, the known ice drill does not completely clean the wells of ice chips when it is removed.

Цель изобретени - предотвращение забивани лунки при извлечении ледобура .The purpose of the invention is to prevent clogging of the hole when extracting an ice screw.

Указанна цель достигаетс тем, что в ледобуре, содержащем режущую головку, выполненную в виде сферического пустотелого корпуса с резцами , и окнами, и приспособление дл удалени лед ной крошки, приспособление дл удалени лед ной крошки представл ет собой заслонку с изогнутыми лопаст ми, окно выполнено в виде щели в нижней части корпуса, резцы установлены так, что их рабоча часть выходит за пределы головкиThis goal is achieved by the fact that in an ice drill containing a cutting head made in the form of a spherical hollow body with incisors and windows, and a device for removing ice chips, the device for removing ice chips is a gate with curved blades, the window is made in the form of a slit in the lower part of the body, the cutters are installed so that their working part extends beyond the head

в зоне, а поверхность резцов дл отвода крошки изогнута по внутренней поверхности головки, при этом лопасти заслонки расположены над резцами так, что перекрывают щель.in the zone, and the surface of the incisors for the removal of chips is bent along the inner surface of the head, while the blades of the valve are located above the incisors so that they overlap the slit.

20 лед ной крошки соответственно).20 ice chips, respectively).

Ледобур содержит режущую головку, выполненную в виде сферического пустотелого корпуса 1 с резцами 2 и 3, шнек 4, штангу 5 с ручкой 6 на кон25 це , плечо 7 с ручкой 8 и приспособление дл удалени лед ной крошки, сферический пустотелый корпус 1 имеет окно 9 дл прохода лед ной крошки по шнеку 4. Окно 9 выполнено в Ice screw contains a cutting head made in the form of a spherical hollow body 1 with cutters 2 and 3, auger 4, a rod 5 with a handle 6 at the end, a shoulder 7 with a handle 8 and a device for removing ice chips, a spherical hollow body 1 has a window 9 for the passage of ice chips on the screw 4. Window 9 is made in

Claims

30 a slit in the bottom of the casing 1. The ice crumb removal device is a 10 G shutter with curved blades. Cutters 2 and 3 are fixed with screws 11 and mounted so that their working part extends beyond the cutting head in the slot area, while the surfaces of cutters 2 and 3 for bending the crumbs are bent along the inner surface of the cutting head. The blades of the valve 11 are secured by screw 12 and are located above the incisors 2 and 3 so that they block the gap from the possible passing of the ice crumb. Ice screw works as follows. When drilling an ice hole, ice on the crumb continuously goes up through the screw 4 through the spherical hollow body 1 with a valve 10 that prevents the crumb from passing into the hole (this eliminates the need to periodically deliver the ice drill from the hole.) You should hold the handle 6 with the other hand and the ice handle with the other hand and rotate the ice hole with the flow or ice hole. When drilling, the spherical hollow body 1 does not detach from the center of the hole or knock on its edge. Dobour prevents ice chips from clogging while drilling and when removing them from the hole. Formula of Ice Break containing a cutting head made in the form of a spherical hollow body with incisors and windows, and a device for removing ice chips, characterized in that to prevent clogging of the hole when removing the icebreaker, the device for removing the ice crumb sets up the valve with curved blades, the window is made in the form of a slot in the lower part of the body, the cutters are set so that their working and a part extends beyond the head in the zone, the surface of the incisors for removal of crumb is bent along the inner surface of the die, while the blades of the valve are located above the incisors so that they overlap the slit.
