Fig1

The invention relates to mechanical engineering, in particular to the grinding components of agricultural machinery, specifically to the layout and parameters of the silo line of fodder harvesting combines.

The aim of the invention is to increase the productivity of a forage harvester.

Figure 1 shows the layout of the grinding apparatus, the silo line and the flow accelerator of a forage harvester; FIG. 2 is a view A of FIG. one.

The silo line 1 (Fig. 1 of the forage harvester 2 is telescopically connected to the section of the chopping apparatus 3 into which the chopping drum 4 is installed. In the channel of the silo line 1 (Fig. 2) a rotor blade flow accelerator 5 is installed. The channel is narrowed by tilting at an angle a side walls 6 of the channel The flow of the process in the channel of the silo 1 is as follows.

By the grinding drum 4, the technical product is thrown into the narrowing part of the channel of the silo duct 1 in the direction of the flow accelerator 5, which acts on the crushed technical product with blades and throws it out in the channel of the silo 1, while the grinding drum 4 gives the particles of the crushed technical product a certain speed and direction. movement.

In addition, it is necessary to observe the condition under which the trajectories of movement of all particles on the narrowing section of the channel of the silo duct 1 must converge in one

B at a 11 - 12 °,

the zone where it is necessary to place the beginning of the outer diameter of the blades of the flow accelerator for co-5114 to the particles of the technological product of additional energy for their further movement along the channel.

The beginning of this zone of installation of the outer diameter (figure 2) is determined from the condition L-I 2tga

where L is the width of the silos-conduit in the area of the chopping drum; I - the width of the narrowed section of the channel

the silo pipe;

a is the angle of inclination of the canal walls. Only if this condition is met, a stable process flow is guaranteed and the silo duct clogging is prevented.

Claims (1)

Claims Silo line of a forage harvester comprising a body made in the form of a chute with walls forming a channel of movement of crushed particles of a technological product with a narrowing section, flow accelerator, which is designed to increase the productivity of the forage harvester of the flow accelerator blades is located from the beginning of the narrowing section of the channel at a distance B, determined from the condition  pri 11-12 °, where L is the width of the pipeline in the area chopping drum; I - width of the narrowed area silo channel; and - the angle of the channel walls.
