Abstract

The invention relates to the field of agricultural engineering. The invention makes it possible to increase productivity by reducing the compacted structure of the material fed in the form of an endless ribbon to a pressing device. The initial wet material is pressed in the screw by the forging feeder 4, at the exit of which it is driven into rotational motion by the blades 12 mounted on the auger shaft and fed to the fixedly mounted forming knife B with the guide surface 9. The material cut by the knife 8 is directed to the guide surface 9 It comes in the form of a continuous tape into the press space formed by the eccentrically mounted filter 2 and pressure 3 drums, where during their rotation the juice is pressed. 3 il. i (L

The invention relates to agricultural machinery, mainly to devices for squeezing juice from green plants in the production of feed concentrates.

The purpose of the invention is to increase productivity by maintaining the compacted structure of the material supplied as an endless band into the press space.

FIG. 1 shows a press, longitudinal section; in fig. 2 - view of the end of the feeder from the side of the knife; in fig. 3 is a view A of FIG. 2

The press consists of a drive filter drum 2 mounted on frame 1 and eccentrically located inside it, forming a press space 3, pressure drum 3, screw feeder 4 and discharge device 5 gradually decreasing in the direction of movement of the material. The feeder 4 consists of a screw 6 enclosed in a cylindrical body with a hopper 7. A knife 8 mounted perpendicular to the auger shaft and located in a vertical plane for forming from an endless belt material compressed in the feeder is installed at the output of the feeder. The knife is provided with a guide surface 9 for placing the belt into the press space.

The knife 8 and the guide surface 9 are fixed in place, for example, on the case of the feeder 4 or the press frame 1, the cutting edge of the knife 10 bridging the gap between the screw shaft 6 and the case of the feeder 4, and the guide surface 9 tangentially tangent to the surface of the screw shaft 6.

The blades 12 are mounted on the screw shaft in front of the knife in order to give the pressed material a rotary

movement. The filter drum is mounted on the support rollers 13. The press operates as follows.

The original wet material is poured into the hopper 7 of the feeder 4, from where it is captured by the screw 6 and pressed when moving along the feeder. Moving progressively

The compressed material at the exit of the feeder 4 is captured by the blades 12 and is rotated. Thus, the material at the exit of the feeder has two movements: translational

and rotational. Due to this, it is cut along a helix by a fixedly mounted knife 8. The resulting endless ribbon of the original pressed material slides along the guide surface 9 and is uniformly fed into the press space. At the same time, there is no violation of the resulting structure of the material pressed into the feeder and its loosening.

the The juice is pressed while the drums 2 and 3 are rotating and released through the perforations of the filter drum.

The pressed material is removed from the press by the discharge device 5.
