Description

The invention relates to agricultural machinery, in particular to presses for senosolous materials.

Known presses for senosolous materials, including a receiving chamber adjacent to the loading hopper and a pressing chamber located behind it with a piston installed in them [1] and £ 2].

However, well-known presses have low productivity, which reduces their performance. .

The aim of the invention is to increase the productivity of the press.

This goal is achieved by the fact that the press is additionally equipped with a backpressor chamber located between the receiving and pressing chambers and adjacent to the loading hopper with a briquette ejector installed in it, and the piston has a protrusion entering the pressing chamber, the height of which does not exceed the height of the piston.

In FIG. 1 shows a press for senosolous materials, side view during the working stroke of the piston; in FIG. 2 the same when idling the piston.

The press for senosolous materials contains a receiving chamber 2 adjacent to the loading hopper 1 and a pressing chamber 3 located behind it with a piston 4. A compression chamber 5 is located between the receiving 2 and the pressing 3 chambers, adjacent to the loading hopper 1 and having a briquette ejector 6. The piston 4 has a protrusion 7, which enters the compression chamber 3, whose height does not exceed the height of the piston 4. At the outlet of the compression chamber 3, a regulator 8 ·, of briquette density, is installed.

The press is used as follows. .

When the piston 4 is operating, the senosolous material coming from the hopper 1 into the receiving chamber 2 is partially pushed into the pressing chamber 3 by the protrusion 7 and partially compressed in the prepress chamber 5. When the piston 4 is reverse, the ejector 6 moves the compressed material from the prepress chamber 5 to the pressing chamber 3 and returns to its original position. At the same time, the next batch of material enters the receiving chamber 2 from the hopper 1. In the next working stroke of the piston 4, two briquettes are formed at once - one of the pre-compressed feed that has come from the prepress chamber 5, and the other from the material located in the receiving chamber 2. Further, the pressing process is repeated.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to presses for haymaking materials. Known presses for haymaking materials include a receiving chamber adjacent to the feed hopper and a pressing chamber placed behind them with a piston 11 and 2 installed in them. However, the known presses have low productivity, which reduces their performance. . The aim of the invention is to increase the productivity of the press. This goal is achieved by the fact that the press is additionally equipped with an underpressure chamber located between the receiving and pressing chambers and a subpress chamber adjacent to the loading bunker with a briquette ejector installed in it, and the piston has an outlet that does not exceed the height of the pores. . FIG. 1 shows a press for hay materials, side view at a working stroke of the piston; in fig. 2 the same when idle the piston. The press for hay materials contains a receiving chamber 2 adjacent to the hopper 1 and a pressing chamber 3 behind it with a piston k installed in them. Between the receiving 2 and the pressing 3 chambers there is a pre-pressing chamber 5 adjacent to the loading bunker 1 and having a briquette ejector 6. The piston k has a protrusion 7. entering the pressing chamber 3, the height of which does not exceed the height of the piston C, the output of the pressing chamber 3 installed 8- regulator, the density of briquettes. The press is used as follows. . 39 When the piston stroke k moves, the hay-straw material coming from the hopper 1 into the receiving chamber 2 is partially pushed into the press chamber 3 by the protrusion 7 and partially partially held in the pre-pressure chamber 5. During the reverse stroke of the piston k, the ejector 6 moves the compressed material from the compression chamber 5 into bale chamber 3 and return to the initial position. At the same time, the next portion of material enters the receiving chamber 2 from the bunker 1. At the next working stroke of the piston C, two briquettes are formed at once - one of the pre-compressed feed, which came out of the pre-compression chamber 5, 1 the other of the material in the receiving chamber 2. Further, the pressing process is repeated. Such an embodiment of the press makes it possible to increase its productivity by forming two briquettes during the working stroke of the piston. Claims of a press for hay materials, including an inlet chamber adjacent to the loading and ingging bunker and a pressing chamber placed behind it with a piston installed, which is characterized in that the press is additionally equipped between the inlet and the compression chambers and the adjacent a pre-press chamber with a briquette ejector installed in it to the hopper, and the piston has a protrusion entering the press chamber, the height of which does not exceed the height of Orshn.
