Description

The invention relates to techniques for fishing equipment intended for drilling holes in the thickness of ice, and more particularly to devices with a mechanized drive of a screw-knife part.

Known designs of screw ice drills made with a manual drive of the screw-knife part. Such ice drills are made of a screw-knife part and a winch, which are interconnected by a hinge, necessary for the convenience of transporting the ice drill, which is folded for this purpose, by folding the screw-knife part 180 ° from the hinge with a hinge. And before the work of the ice drill, the hinge on the hinge is rotated 180 ° in the opposite direction and is rigidly fixed, for example, with a bolt and nut. After assembly, the shaft of the screw-knife part forms, with the collar shaft, a structurally unified collection shaft with a single axis of rotation. The screw-knife part is made of a hollow lightweight shaft, to the surface of which from one side there is a single-start screw blade rigidly attached by welding, while the shaft end part and the blade are equipped with a crossbar to which, as a rule, two mortise knives are attached at a certain angle [ 1] and [2].

A disadvantage of such a known ice drill device is that its auger blade is made in the form of a tape with which, during ice drilling, ice crumbs are squeezed to the periphery of the blade due to centrifugal force and can then fall into the gap between the wall of the hole and the screw. When such a screw-knife part is pulled out of the hole, the ice crumb also easily falls off the screw blade again into the hole. Therefore, and especially in severe frost and with a large thickness of ice, repeated and unproductive work is carried out to remove dry ice crumbs from the hole, which reduces the productivity of drilling the hole and increases the physical fatigue of the angler.

The closest technical solution, selected as a prototype, is “Gasoline ice drill” [3], which is made of a screw-knife part, an extension shaft, two handles and a gas engine with gearbox. The screw-knife part is made of a shaft to which one typical helical blade and two knives are welded.

The disadvantage of the prototype is that the gasoline engine while drilling ice creates significant noise and clogs the surrounding atmosphere with combustion products. A gasoline engine needs fuel to operate, which together with the engine creates a significant weight of the entire device. In addition, during ice drilling, ice crumbs due to centrifugal force are squeezed to the periphery of the blade and can then fall into the gap between the wall of the hole and the screw, and when such a screw-knife part is pulled out of the hole, the ice crumb also easily falls off the screw blade again into the hole .

The problem to which the invention is directed, consists in the complete exclusion of gas pollution and in reducing noise pollution of the environment, as well as in increasing the efficiency of ejection of ice crumbs from the hole during its drilling and, in addition, in reducing the weight of the entire structure of the ice drill, in reducing physical tired fisherman.

This is achieved by the fact that the ice drill with a mobile electric drive, made of a screw-knife part, consisting of a hollow shaft, to one of the ends of which a horizontal bar with removable knives is welded, and one screw blade is welded to the shaft surface from the side of the crossbar, while to the second end the shaft is detachably connected to an extension shaft and a gearbox with an engine and two handles, and the gearbox housing is equipped with a tubular nozzle in which the gearbox input shaft is coaxially located; in the shaft end, transverse to the shaft only a conical hole is made from the end of the shaft to the transverse hole, through which a household cordless electric drill is detachably connected with its shank, the shaft axis of which is placed at an angle of 90 ° with respect to the shaft axis of the screw-knife part connected to the output shaft of the handle gearbox, one in the form a detachable tube with a handle is installed relative to the second, made in the form of a drill, at an angle from 90 to 120 ° from the axis of the drill shaft, a tube with a handle is detachably installed, in addition, the wall of the tubular nozzle from the side of the end fitted with longitudinal grooves, and on the outer surface equipped with a split ring with a clamping bolt, in addition, the extension shaft is equipped with an additional folding handle located at a height L from the tops of the knives, while the auger blade on the side of the working surface is equipped with a side that is welded to the periphery of the working surface the blades at individual points, in the intervals between which the board is equipped with through grooves located at a certain step from each other. The tube with a handle and the shaft of the screw-knife part are equipped with threaded union nuts. The gearbox is made of a multi-way worm and a multi-way gear connected in a screw connection with intersecting axes. The worm is made of steel, and the gear wheel is made of polyamide.

The invention is illustrated by drawings, where figure 1 shows a General view of the ice drill. Figure 2 shows the view of the ice drill in the direction of arrow A. Figure 3 shows the shaft cutout of the screw-knife part with the hinged handle in the closed position. Figure 4 - the same handle in the open position. Figure 5 shows an enlarged recess illustrating the mechanical connection of the electric drill with the gearbox through a tubular nozzle. Figure 6 shows the ridge of the screw-knife part, explaining the placement of the grooves of the side.

The ice drill device includes a screw-knife part 1, consisting of a hollow shaft 2, to one of the two ends of which a crossbar 3 is welded, to which removable knives 4 are attached. One screw blade 5 is welded to the surface of the shaft 2 from the side of the crossbar 3. To the second end of the shaft 2, the extension shaft 6 and the gearbox 7 are detachably and sequentially connected. The gearbox housing 7 is equipped with a tubular nozzle 8, in which the input shaft 9 of the gearbox 7 is coaxially located. A transverse hole 10 is made in the end part of the shaft 9, and from the end of the shaft 9 to the hole The hole 10 has a tapered bore 11. A tapered shank 12 belonging to the cordless electric drill 13 is inserted into the tapered bore 11. The axis 14 of the shaft of the electric drill 13 is positioned relative to the axis of the shaft 6 at an angle α. The shaft 2 through the extension shaft 6 is detachably connected to the output shaft 15 of the gear 7. Between the axis 14 of the shaft of the electric drill 13 and the axis of the shaft of the tube 16 having a handle 17, an angle φ can be set at the request of the angler. A discrete change in the angle φ is performed by a hinge 18 and a fixing bracket 19. The wall of the tubular nozzle 8 is provided with longitudinal grooves 20 on the side of the end, and on the outer surface of the nozzle 8 is equipped with a split ring 21 having a coupling bolt 22. The extension shaft 6 is provided at a height L from the tops of the knives 4 by a folding handle 23. The blade 5 on the side of the working surface is provided with a bead 24. The bead 24 has through grooves 25, which are made in step S. The tube 16 is connected to the hinge 18 in the same way as shaft 2 to the shaft 6 and shaft 6 to the output shaft 15 using union threads bean nuts 26. The gear 7 is made of a multi-start worm 27 and a multi-start gear 28. The length h of the tube 16 with the handle 17 can be replaced by a longer or shorter one at the request of the angler.

The ice drill works as follows.

Previously, all detachable nodes of the device are connected to the ice drill design. Then, with the left hand, they take hold of the handle 17, and with the right hand hold the handle of the electric drill and set the ice drill on the supposed ice drilling point. Next, with the index finger of the right hand, press the start contact and, if necessary, fix it with a button (available on the electric drill handle) and, while holding the ice drill in a vertical position, without special physical stress, they only monitor the penetration of the screw-knife part 1 into the ice. After the passage, the ice strata is intercepted with the right hand on the handle 23 and the screw-knife part 1 is easily removed together with the ice sludge from the drilled hole, while a significant part of the water that is saturated with ice crumbs flows through the through grooves 25, and the remaining ice crumbs are quickly shaken off, freeing the auger from it. Then the ice drill is ready for the next drilling.

The usefulness of the claimed device lies in the fact that, in comparison with the prototype, smoke-free environment is eliminated; noise level is reduced, and this reduces the deterrence of fish and, thus, increases the catchability of the place. In addition, in comparison with the prototype, the weight of the entire ice drill device is reduced, the launch of the ice drill is facilitated, namely the rotation of the screw-knife part. The absence of easily flammable and explosive liquids in the structure of the ice drill design, which is important when transporting the ice drill. The absence in the design of the electric ice drill drive of specifically smelling liquids, such as combustible gas engines, the smell of which can fall on your hands and then on the bait, which will scare away the fish. The presence of a bead on the periphery of the working surface of the blade of the screw-knife part will allow more efficient removal of ice sludge from the hole. The presence of grooves in the side of the blade contributes to the rapid drainage of water and the facilitation of the screw-knife part, which means reducing the physical fatigue of the fisherman.
