(54) PLANETARY GRINDER

 one . The invention relates to the technique of grinding materials, in particular, to mechpichitel for cutting current conductors in enterprises of secondary non-ferrous metallurgy. A rotary chopper is known for current-carrying conductors of the IPR type, consisting of a cylindrical cutting chamber with a discharge grid and a loading window. Inside the cylindrical chamber there is a rotor with knives fixed on it l. The current-carrying conductors entering through the loading window in small beams (portions) enter the zone of action of the rotating knives, cut them into small pieces and pour out through the discharge grid. In this grinder cutting pro. The current conductors are produced by pairing lines, however, for better grinding of the current conductors and removing the insulation from the insulation, it is advisable to cut the beam in different intersecting planes. A grinder is also known, containing a spherical working chamber consisting of two hemispheres, one of which is. They are mounted with the possibility of vratzen and equipped inside with a knife shaft, which is connected to a fixed hemisphere by means of a bevel gear and a drive. During the rotation of the drive bevel gear, the cutting knives of the chopper make a complex rotational movement 2. The material entering the chopping through the hopper enters the working chamber, is cut by knives from different sides and leaves the chopper through the discharge window. This grinder is closest to the proposed invention. The disadvantage of this shredder is the low efficiency of shredding the mother of the shaft. This is due to the fact that the cutter shaft is installed in the upper hemisphere, rotating in a horizontal plane, as a result of which the material does not grip during the grinding process and is able to catch it, grinding and unloading is unfavorable.

The purpose of the present invention is to increase the efficiency of the grinding process.

This goal is achieved by the fact that in a planetary chopper, mainly for current conductors in polymorphic radiation, including a spherical chamber, consisting of two hemispheres, one of which is installed with a possibility of verticalization and is provided with a shaft with a knife is Mi The spherical chamber is mounted obliquely to the horizon, the S shaft with notes is mounted in the lower hemisphere, which is rotatable. The knives are alternately attached to the shaft rigidly and hinge but.

FIG. 1 shows a general view of a shredder; in fig. 2 is a section along A-A in FIG. 1..25

A planetary chopper consists of a spherical inclined cutting chamber 1 made of two hemispheres: a lower rotating hemisphere 2 with an unloading 1 grate 3 and an upper non-30 moving hemisphere 4 with a loading window 5. In the lower hemisphere there is a cutter shaft in, fixed to it a rotor 7 with cutting bodies (cut-off knives) 8. For a better grinding and isolation of the current conductors, both the articulated suspension of sickle-shaped knives to the rotor and their rigid attachment is provided. Ineni .40

The internal cavities of the upper and lower oluspheres form a spiral tilting chamber for cutting conductors, the radius of which is slightly longer than the length of the longest sickle knife. At the end of the blade shaft 6 outside the cutting chamber, an implanted satellite 9 is mounted, which is exactly the same with the fixed conical wheel 10 and the lower bowl 2 serving as a carrier,

constitutes a conical planetary gear designed to communicate a crescent-shaped knife of complex rotational motion.

For shaving the efficiency of the grinding process and creating at the bottom of the cutting chamber the best conditions for shifting and. unloading of crushed current spans, bottom hemisphere with knife 707600

The shaft is set obliquely at an angle to the horizon.

The chopper works as follows

With the rotation of the lower hemisphere 2 koni. The satellite 9 performs a complex planetary motion. Together with the conical satellite, a knife shaft 6 with crescent-shaped knives 8 fixed on it also makes a complex movement. The knives, however, rotate around the axis of the knife shaft b, and also, together with the knife shaft, around the axis of the cutting chamber 1, i.e. make a complex rotational motion in mutually perpendicular planes. The current conductors entering the cutting through the discharge window enter the zone of action of the rotating knives 8, wedge between the walls of the cutting chamber 1 and the sickle-shaped blades (see Fig 2), cut them and pour into the lower hemisphere. In the lower hemisphere, under the action of inertial forces and gravity, as well as under the action of rotating knives, the conductors are intensively mixed, as a result of which the efficiency of the process of grinding the conductors and the unloading condition through the grate are improved.

The rotational movement of the lower hemisphere can be communicated by ra; in various ways.

The technical advantages of the proposed planetary shredder consist in increasing the efficiency of the grinding process of TOiTa conductors and, as a result, in reducing the unit cost of energy for cutting them. .
