Abstract

A COTTON-EQUIPMENT DRUM SPINDLE DRIVE, containing coaxially mounted spindle-mounted drive friction elements, interacting with the forward and reverse rotational belt tracks, characterized in that, in order to ensure the rotation of the spindle with different speed patterns, one can create a sharpener with reverse speed and reverse rotation, in order to ensure the rotation of the spindle with different speed patterns, and with the same sharpening rotation and reverse spins, with the purpose of ensuring the rotation of the spindle with different speed patterns, and with the same speed sharpening and reverse spins. , the drive element of each spindle is made with an increasing diameter in its height, and the forward rotation track has a variable cross section along its length, the cross section to The ends of the sections are made equal and larger than the middle section, while the reverse rotation track is installed with the possibility of interaction with the largest diameter section of the drive element of each spindle, and the end sections of the forward vraza track are installed with the possibility of interaction with the smallest diameter section of the drive element of each spindle.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery and can be used in cotton harvesting machines.

A spindle drum is known, containing spindle drive rollers in contact with the forward and reverse spindle tracks, the first of which is shaped by a part of an ellipse of the greatest radius of curvature of the carrier, which is a telescopically articulated element connected by a spring, carrying spindles and additional rollers in contact with the guided cam mounted on the frame of the apparatus 1.

The disadvantages of such mechanisms are low agronomic indicators and manufacturing complexity.

Also known is a drive mechanism for the spindles of a cotton harvesting machine, including outer and inner fixed tracks and drive friction rollers of the spindles supported on the fingers, where the spindles with the drive rollers are connected to the support fingers of the spring 2.

The main disadvantage of this design is the failure to provide an accelerated mode of rotation of the spindles in the cotton harvesting area, which reduces agrotechnical indicators, and the presence of spring support fingers slightly reduces the reliability of the mechanisms in operation.

The purpose of the invention is to increase the reliability of the drive by providing the required angular velocity of the spindles in the working areas.

The goal is achieved by the fact that in the drive of the spindles of the drum of the cotton-harvesting apparatus containing & their coaxially mounted with the spindles their drive friction elements interacting with the belt tracks of forward and reverse rotation, they are made with an increase in its height rotation has a variable cross section along its length, and the cross section of the end sections is made of equal size and larger middle section, while the reverse rotation path installed

with the possibility of interacting with the largest diameter section of the drive element of each pin, and the ends of the direct rotation track are installed with the possibility of interacting with the smallest diameter section of the drive element of each spindle.

FIG. 1 shows the proposed drive of the spindles of a cotton-picking drum, top view; in fig. 2 shows section A-A in FIG. 1 in two versions; in fig. 3 - reamer belt (ring wheel) in two versions.

The proposed drum spindle drive comprises a belt track 1 for direct rotation (ring wheel) made curved (a) with zones M and N or stepped (b) with zones X, Y and Z to provide the necessary angular velocity, drive rollers 2 made tapered (a) or stepped (b), also to provide the necessary angular velocity, track 3 reverse rotation (sun wheel), drove 4, spindles 5, guide cam 6 and additional rollers 7.

The entrance to the working zone, the lower zone M of the drive roller 2 (a) comes into contact with the zone of the M belt track 1 (a) and the spindle 5 gains a high angular velocity, which is necessary when entering the working zone. When the upper zone N of the drive roller (a) comes into contact with the zone N of the belt track 1 (a), the angular velocity of the spindle 5 gradually decreases, and when the drive roller 2 (a) enters the zone of the M belt track 1 (a), the angular velocity again increases. A similar change in the angular velocity for the drive roller 2 (b) upon contact with the belt track 1 (b) in the zones X, Y and Z.

In the pickup zone P, the belt track 3 contacts (upper) zone N of the drive roller 2 (a) or zone Z of the drive roller 2 (b) in order to reduce the angular velocity to ensure complete removal of cotton from the spindles 5. The radius of the carrier 4 does not change, The link carrier 4 remains rigid. This increases reliability, performance in the drive of the drum spindles, and also simplifies the design of the drum.
