Description

 , one

The image is related to the mining industry and is intended for the development of salt deposits.

The purpose of the invention is to increase reliability.

FIG. 1 shows the reversing organ, general view; FIG. 2 - section A-A in FIG. 1; in fig. 3 - section BB, fig, 1; in fig. 4 shows the node T in FIG. 1 | in fig. 5 shows an embodiment of a connecting link in the form of a multilink; in fig. 6 - pasi- cut BB in FIG. 5; in fig. 7 shows an embodiment of the assembly I in FIG. ; in fig. 8 - section G-Y in FIG. 7

The reversible working body of the combine consists of a drum 1 with a hub 2, rotary blades 3 with a cutting tool 4 and 5, pivotally mounted on the drum 1 with the help of fists 6 and 7 ,.

The rotary blades 3 are pivotally connected to each other by means of a connecting link 8, fulfilled in the form of a ring. Holes are located on the connecting link 8 (grooves 9, equidistant from the axis of rotation of the drum 1, and the major axes of the holes pass through this axis and form m "1 each being equal central angles

On the pivot blades, axles 10 are located, which are located on a line dividing the pivoting blades 3 in half and passing through the axis of rotation of the cams 6 and 7, on which the pivoting blades are fixed.

The connecting link 8 is centered about the axis of the drum 1 by the points of contact formed by the inner cylindrical surface

ring 8 and the cylindrical surface of the fists 6, which are fixed rotary blades 3,

The connecting link 8 can be made 5 in the form of a multi-link, each link of which is connected to the rotary blades 3 by means of the axes 10.

It is possible that the connecting link 8, made in the form of a ring, may have axes 10 located on a circle equidistant from the axis of rotation of the drum and forming equal central angles among themselves. These axes mate with ellipsoid orifices 9, the major geometric axes of which are located on a line that halves the rotating blades 3 and passes through the axis of rotation of the fists 6, I

The device works as follows.

When the reversing tool rotates counterclockwise, the cutting tool 5, located on the rotary blades x 3, comes into contact with the salt layer with its back side and the reaction force of the layer turns the blade 3, preparing the cutting tool 4 for work (cutting salt). the blade is hingedly connected with all the blades of ring 8, then at the same time 35 all the blades are rotated into the working position.

When the reverse tool rotates in the opposite direction, the process of rotating the blades is repeated - 40,
