Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the working bodies of fodder harvesting and feed grinding machines.

The aim of the invention is to reduce energy consumption and simplify the design.

Fig, 1 schematically shows the pipeline, side view; figure 2 is an active reflector with notches

The discharge pipe consists of a rotary part 1 and a fixed base 2, in the cavity 3 of which, adjacent to the channel 4 for the passage of the crushed mass, an active reflector 5 is installed, made in the form of a smooth drum. The base is made of the lower 6 and upper 7 parts, the front walls of which 8 and 9 are located at an angle of 90-180 ° relative to one another. The longitudinal axial plane 10 of the upper 7 part of the base 2 is located tangentially to the cylindrical forming 11 of the active reflector 5, and the longitudinal axial plane 12 of the lower part 6 intersects the cylindrical forming 11 of the active reflector 5. The surface of the active reflector 5 is provided with notches 13. The unloading pipeline is connected to the grinding apparatus 14.

The device works as follows.

The vegetable mass crushed in the grinding apparatus 14 is fed through the channel 4 of the fixed base 2 to the active reflector 5, which rotates in the opposite direction relative to the grinding apparatus. The outer shell of the grain is destroyed by the impact with the surface of the active reflector. Due to the notches 13 there is a better grip

grains with an active reflector surface. Under the influence of an active reflector, the particles of mass are ejected tangentially of its mass forming the upper part 7

the base of the pipeline 2.

Due to the impact and twisting over the surface of the active reflector, only the outer shell of the grains is destroyed, which allows to reduce the energy intensity of the active reflector by 20% compared with the prototype.

Due to the proposed geometry of the front walls at an angle of 90-180 °, the ground mass moves along

the channel of the discharge pipeline with minimal friction against the walls, thereby reducing by 1.5-2 times the energy required for mass transportation.

In addition, due to the elimination and the need for additional strengthening of the walls, their metal content is reduced,
