FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to presses for briquetting feed materials.

The purpose of the invention is to increase productivity and reduce energy consumption.

FIG. 1 shows a stamp press, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the location of the end ends of the Popping tongues at the inlet of the pressing channels,

A stamp press consists of a housing 1, in the center of which a loading device is rigidly mounted, consisting of a channel with a variable section 2, in the upper part of which a loading window 3 is located, and a swinging sectional piston 4 placed inside it. Channel 2 is connected to receiving chambers 5, and the channel cross section is narrowed ms from the center to the receiving chambers. In the side

press performance. Piston A, turning, moves the material towards the receiving chambers 5, with

this causes it to be pre-compacted, with the result that air is removed from it. At the same time, the main part of the air is removed in the wide part of the channel, when

0 between the walls of the channel and the piston is a large enough gap, which significantly reduces the resistance of the air outlet and reduces the energy intensity of the pressing. The material is compressed

5 by stamps 13 and pressing into the pressing channels 14. But, since the ends of the bridges 15 at the entrance of the pressing channels are made at an acute angle to the walls, the material slides through when the stamp is applied to it, which reduces the energy intensity of the process. During the reverse of the stamps, the material caught in the interstices of the channel grooves 6 are made. Por-25 is stamped out by the partitions 10 into the receiving chamber, and the material in the opposite receiving chamber is pressed into the pressing channels.

Invention Formula Stamp press, including boot device, traverse. Shen 4 is connected to shaft 8 by means of strips mounted in bearing-bearing 9-on housing. The receiving chambers are separated by partitions 10 rigidly fixed in the housing, between which are located with the possibility of reciprocating movement of the yoke 11. Traverse connected by means of intermediate elements 12 thirty with a drive (not shown). On traverse 35 Installed with the possibility of returning "1and .. 1", stamps of 13 square sections are installed. To both sides of the receiving chambers 5, press channels 14 are located, which are separated by bridges 15. The ends of the bridges at the entrance to the press channels 40 are located at an acute angle to the walls of the channels. Stamp press works as follows.  The extruded material is fed through a loading window 3 into a channel with a variable cross section. 2. Since in the center the channel has a larger cross section, a large portion of material is loaded into it, which makes it possible to increase but with forward movement, with its stamps fixed on both sides, receiving chambers and pressing channels separated by interlaces, characterized in that, in order to increase productivity and reduce energy consumption, the loading device is completed as a channel with a variable cross section decreasing from the center to the receiving chambers, inside of which is installed the oscillating sectional piston, and at the entrance of the pressing channels. The faces of the jumpers are located at an acute angle to the walls of the channels. press performance. Piston A, turning, moves the material towards the receiving chambers 5, with this causes it to be pre-compacted, as a result of which air is removed from it. At the same time, the main part of the air is removed in the wide part of the channel, when there is a sufficiently large gap between the walls of the channel and the piston, which significantly reduces the resistance of the air outlet and reduces the energy intensity of the pressing. The material is compressed stamps 13 and pressing into the pressing channels 14. But, since the ends of the bridges 15 at the entrance of the pressing channels are made at an acute angle to the walls, the material is slid when the stamp is applied to it, which reduces the process's energy intensity. During the reverse of the stamps, the material that fell during interstitial motion, with its stamps fixed on both sides, receiving chambers and pressing channels, separated by jumpers, characterized in that, in order to increase productivity and reduce energy intensity, the loading The device is made in the form of a channel with a variable cross-section, decreasing from the center to the receiving chambers, inside of which there is a swiveling section piston, and at the inlet of the pressing channels laid at an acute angle to the walls of the channels. 15 14 Phie.g 11 10 one
