Description

The invention relates to the textile industry and can be used for the cleaning of raw cotton from small weed impurities in cotton plants. The aim of the invention is to increase the efficiency of the distribution of food. The drum contains perforated shell and hollow perforated blades, on the front part of which longitudinal slit holes are made. 3 sludge.

The invention relates to the textile industry and can be used for the cleaning of raw cotton from small weed impurities in cotton plants.

The aim of the invention is to increase the efficiency of the distribution of food.

Figure 1 shows the drum, cross section: figure 2 - the same, side view: in fig.Z - drum as part of the cleaner of the fibrous material.

The drum contains a perforated shell 1 and hollow perforated blades 2, the front part of each of which is a longitudinal slotted hole 3. The width of the gap can be adjusted by compressing or unclamping the mesh surface of the blade 2.

Example. The cleaner contains a shaft 4 with feed rollers 5, perforated working drums with exciting raw cotton blades 2, curved drum caps 6 with pegs, reeling grids 7. discharge shaft 8 and a bunker 9 for dumping.

The working drums inside the hollow and weed impurities are released inside the drums.

The drum cleaner works as follows.

Raw cotton from the shaft 4 is fed by the feed rollers 5 to the first working drum and is thrown over the top of another drum, etc., until it is unloaded from the cleaner through the hopper 9.

When the raw cotton strikes the net surface and the pegs of the lids 6, small weed impurities enter the drums, stand out from it under the action of centrifugal force through the holes 3 and the perforation of the nets in the lower part of the drums and then wake up through the grid 7 into the bunker 9, from where they are removed from the cleaner .

Under the drums, a perforated mesh 7 is installed to prevent the piece of cotton and straw falling under the drums from falling out with the litter. The cleaning of this raw cotton is carried out in the same way as in the famous drum.

2 with holes Knowing their tops allows to increase the area of the mesh surface for the selection of litter.

The use of blades 2, the top of which has gaps smaller than the size of the bat along the length of the drums, also makes it possible to increase the cleaning efficiency of raw cotton due to the fact that weed impurities free from bonds with fiber freely fall through the gaps into the drum from above and are removed from the bottom due to centrifugal action.

The slot width of the blade tips is adjustable to avoid cotton loss, because different breeding varieties, and

they can be processed at the cotton factory by 2-4 breeding, have different sizes of raw cotton bolls.
