Abstract

The invention makes it possible to increase the efficiency and stability of the process of dividing the mass of raw cotton into batches, at the same time classifying it according to the physicomechanical properties and reducing material costs. In the sections, raw cotton is moved, weed impurities are removed through elastic peripheral brush elements, enter the cleaner casing and are removed by the air flow of the pneumatic system. The separation of cotton into battles takes place with brush elements of the rotor and peripheral elements. Classification is carried out sequentially section by section. 6 Il.

Description

The invention relates to agricultural machinery, serves for the primary processing of harvested raw cotton, in particular for dividing raw cotton into batches, followed by sorting (classification) by physicomechanical properties during its transportation, St. No. 1423039.

The purpose of the invention is to increase the efficiency and stability of the process of dividing the mass of raw cotton into batches, at the same time classifying it according to the physicomechanical properties and reducing material costs.

The operations of dividing and classifying raw cotton bats are carried out simultaneously by passing a cotton mass through a transtrusion with elastic elements divided successively into sections,

separating raw cotton into batches and their classification by physicomechanical properties.

The transporting tube is enclosed in a fence having an exit opening equipped with a pneumatic system for removing trash and sorted traces.

The distance between the elastic fibers of the peripheral brush elements of the rods is comparable with the size of the classified cotton leaves.

The guard of the cylindrical core of the device is made of several sections separating the bat, classifying them according to the physicomechanical properties and arranged in series in ascending class along the longitudinal axis of the device, with each section corresponding to a certain spacing of the elastic fibers of the peripheral brush elements of the rods.

Figure 1 shows the proposed device; figure 2 - the rotor; on fig.Z - section aa in figure 1; Fig. 4 illustrates the mechanism of the process of dividing a lobule into batches; figure 5 - section bb in figure 4; FIG. 6b shows peripheral brush elements for I, II, III, IV sections of the device with different spacing of elastic fibers for sorting cotton bales into different classes.

The device consists of fencing sections 1, loading hopper with window 2, hollow shaft 3, electric drive 4 with gear 5, unloading openings 6 sections and storage tanks 7 (shown in section). The hollow shaft 3 is perforated with holes 8 and provided with brush elements 9 with a constant pitch of elastic fibers along the entire length of the shaft.

The rod cylindrical housing — the trans-pipe consists of a shell 10. is rigidly connected with longitudinal tubes-rods 11, on which peripheral brush elements 12 are mounted. Each section 1 is provided with a pneumatic system 13 through shaft 3.

Raw cotton is fed to the hopper with window 2. Raw cotton, moving in a transtrum, in section 1 is divided into batches. At the same time, the weed impurities present in the mass of raw cotton, under the action of centrifugal force, spill into the gaps between the elastic fibers of the peripheral elements 12. The cleaning effect is enhanced by the supply of compressed air through the holes 8 of the hollow shaft 3. Weed impurities that fly out of the transtrum are trapped by the air flow formed by the enclosing sections 1, are snail-shaped and fall out in storage tanks 7 (see FIG. 3).

The mechanism for dividing the raw cotton into separate bits is shown in Figures 4 and 5.

The two coupled batches, which are located between the elastic fibers of the brush elements 9, 9 and the elastic fibers of the core peripheral brush elements 12, 12, and the body of seeds having relative hardness, deflect the elastic fibers from the normal initial position and

in the plane of the brush elements, grooves are formed which repeat the shape of seeds. When the rotor brush elements move (for the sake of clarity, the rotational movement

it is depicted as a rectilinear) a pair of forces is formed - one by the elastic fiber of element 9, resting against the top of the semes, the other by the force of the rest reaction formed by the elastic element 12 supporting the lower

this Thus, there is a shift of the voltages relative to each other and the separation of pairs of volatios.

Further, the peeled and divided flyers fall into section II with peripheral

brush elements (figb). The smallest boulders pass between the peripheral brush elements, are captured by the air flow and are thrown into the storage tank 7.

A similar process is repeated in sections III and IV.

Efficient separation and classification of raw cotton in primary processing allows for the use of a general harvest cotton picker, simpler in design and reliable in operation, reducing harvest time and eliminating manual labor. In addition, the classification of raw cotton by grade allows

to separate higher quality fiber from low grade fiber and to obtain high quality raw materials.
