Abstract

The invention relates to devices for the formation of cuts in the ice of reservoirs. The working body of the device is a b-shaped body 1 with through-cut 2 on the arcuate portion. In notches 2, cutting elements 4, made by horseshoe, are reinforced. The cutting edges of the elements 4 is a broken line. The drive of the working member is made in the form of a gearmotor 6, the rotation of the cranks of which is converted into movement of the housing 1 by connecting rods 7 connected for rigidity by a tight 8. In the cavity of the housing 1 a vertical scoop conveyor 9 is mounted, connected to the drive of the operating member. Blocks 12 are installed for the wiring of fishing gear cables. 2 z p.

Description

The invention relates to devices for the formation of cuts in the ice of water bodies and is intended primarily for use in ice fishing.

The purpose of the invention is to increase the reliability of operation and increase the speed of passage of the slits.

FIG. 1 shows the working body, a general view; in fig. 2 is a section A - A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. 3; in fig. 5 - the device is in working position.

The device for forming slots in ice contains a working body, which is a L-shaped body in cross section 1 with through notches 2 on an arcuate section in which nine elements 4 are fixed by means of screws 3. The latter are installed along the arcuate section and directed by their cutting edges 5 inside the housing 1.

The device comprises a drive and a motion converter. The drive is made in the form of a gearmotor 6, and the motion transducer is in the form of a pair of curved and paddle mechanisms, the crank 7 of which is connected to the housing 1 in its vertical part and between them the thrust 8.

To remove fragments of ice from the slot, it is equipped with a mechanism d, removal, located inside housing 1 and representing a conveyor 9 with scoops 10. A mechanical mechanism for removing fragments is connected with a drive through sprockets 11.

On the motor-reducer biv the lower part of the housing 1, blocks 12 for fishing gear cables were fixed.

The entire device is mounted on a vehicle — a tractor 13, to which it is connected by means of a P1 hinge 14 and a hydraulic cylinder 15, and on the tractor 13 a winch 16 for winding the fishing gear cables is mounted.

The device works as follows.

Upon arrival at the place of work, the hydraulic cylinder 15 lowers the casing 1 until contact with ice, and then turns on the gear motor 6. The rotating curves cause the movement of the H1-tuna 7 with thrust 8, the casing 1 also has circular movement 4 and begin chipping ice, while the hydraulic cylinder 15 continues to lower the housing 1. This process continues until the penetration of the housing I through the ice when the device assumes the operating position (Fig. 5). Further formation of a slit in the ice

It moves when the tractor 13 is moving. At the same time, a cable is pulled along the ice by blocks 12, along the edge of a net.

{The free motion of the cutting elements 4 for the most part, the circular trajectory of their movement, together with the movement of the tractor 13, creates the impact nature of the contact of the re-cut edges 5 with ice, which ensures high cutting efficiency. The frequency of the impacts of the cutting elements 4 is controlled by the speed of rotation of the drive in accordance with the required speed of drawing the water. The fastening of the cutting elements 4 in the notches 2 provides the impact elasticity, and f / -o6pa3HaH

5 case form 1 - structural strength. Ice fragments through the cutouts 2 due to the paclon of the front working surface of the cutting elements 4 enter the cavity of the housing 1, from where they are removed by the conveyor 9. High structural strength can cut a narrow slot in the ice, and a small number of moving parts ensures high efficiency and reliability devices, which significantly increases the cutting speed.
