The new design "concentrator" (Fig. 8) has a radius 1 on the left side of the drum, along the 
length of the decanter 3, decanter part is set at a narrowing distance from the grinding teeth of 
the drum. , the top of the decanter narrows from 35mm to 15mm. The distance between the drum 
and screw 2 has been increased so that the cups do not get stuck inside the "enrichment". A 
barrier 4 is installed at the top of the drum to guide the falling coils from the vertical conveyor 
through the intake chamber to the drum. The movement in the 'enrichment' section is driven by a 
belt through a pulley in the toothed drum and a fan pulley.

The advantage of the recently modernised pick-up machine (Fig. 8) is that it incorporates several 
problematic aspects of existing machines that are currently under development: 
- Low productivity 
- Fast maintenance 
- Price of the body on the machine 
- The 'enrichment' is stuck inside. 
Figure 8. New semaphore "enrichment" 
1-toothed drum, 2- auger, 3- deck, 4- set, 5- guide chamber. 
The new machine type included the following problems: higher productivity by reducing 
the number of drums, reduced distance between drums and augers, reduced maintenance costs 
and primary processing of unopened drums. In the new machine type, the spun cotton is put on 
the mulch, dried and then cleaned in a cocoon cleaning machine. At the farmer's discretion, it can 
be used as livestock feed or as a cotton harvesting machine if the cotton field is 80-90% open 
and the leaves have completely fallen. 
The farmer quickly harvests unopened areas thanks to the high productivity of this new type of 
machine and further increases yields by tilling the land in a short time.
