(54) COTTON CHEESE CLEANER CLEANER

The invention relates to the field of primary processing of raw cotton and can be used in the cleaning and cotton harvesting machines. A raw cotton cleaner is known that contains a cotton debris cleaning unit, including a series of parallel center drums and a grate separator located under them, and a large dust removal unit for cotton, which includes a pilch cylinder with a brush remover i The purpose of the invention is to improve efficiency cleaning up. This goal is achieved by the fact that, in the proposed device, the separator contains a series of parallel-installed belt conveyors with needles on the surface of the belts, and the grate bars are made in the form of grooves and are located along the row of drum carcasses, while the working branches of the conveyors are screws with spikes on the screw surface and with the opposite direction of the screw lines in the adjacent drums. In FIG. 1 shows a schematic of the proposed cleanser; in fig. 2 cleaning section, cross section; in fig. 3 is the same, top view, in FIG. 4 - entrance zone cleaner. The cleaner contains two nodes for cleaning raw cotton from small litter and from large litter installed in the housing 1 with the inlet 2 and the outlet 3 with the branch pipe. The first of the assemblies includes caustic augers 4 and grooved grates 5 located under them with needle-shaped conveyor belts, 6, which constitute separate drainage sections. The second cleaning unit includes a serrate cylinder 7, a brush puller B, a fender drum 9 and a receiving auger 10 for large trash. The entrance area of the cleaner contains a caustic screw 11 and a pair of paddle rollers 12, and a fan 13 serves for the removal of small debris, and a suction pump serves dust from the carbon chamber 14. Under the action of the forced flow of air sucked through the cleaner, raw cotton is fed to the distribution auger 11 and further on two feeding paddle rollers 12, which evenly throw cotton on the sections of the cleaning needles of tape b and round screws 4. The bulk of the cotton will ruffle with akol screws 4 up to

until the raw cotton is released from the shallow litter and goes to the serrate cylinder 7, from which the fender 9 drops large impurities to the receiving auger 10 to remove them from the cleaner, and the cleaned raw cotton from the serrate cylinder 7 is removed with a brush puller 8 and J is directed through the vacuum valve to the outlet 3.

In the carbon chamber 14, the cleaning ribbons 6 are arranged in sections, over which are spiky augers 4 with right and left directions of the screw lines, which creates a complex wave-like movement of raw cotton, increasing its residence time inside the machine with small dimensions of the cleaning body. Alternating the moving sections of the needle tapes with the fixed edges of the grates 5, in addition to the chafing effect of the augers, improves the degree of purification of the raw cotton, which reduces the time it takes for the raw cotton to come into contact with the garbage released from it.

Between the grate bars there are longitudinal gaps, which serve to remove fine litter from the cleaning zone by suction air flow created by the fan 13.

 In order to isolate coarse impurities during the cleaning process, there is a sawtooth section, into which raw cotton is carried out from the area of fine litter.

In the sawed section, raw cotton is thrown onto the saw-like surface of cylinder 7, where the raw cotton slices are kept stronger,

than large weed impurities in the form of cotton sash-boxes.

Under the action of the baffle drum 9, large weed impurities are knocked off the surface of the serrate headset and sent to the receiving screw 10 for taking them out of the machine, and the cleaned cotton is removed by the brush remover 8 to the outlet nozzle 3.
