Description

The invention relates to the agricultural field of technology and is used in vertically spindle cotton pickers.

Known friction drive, for example, the spindles of the cotton picker, comprising a drive belt and a brake device belt made of a more flexible material than the drive belt in contact with the spindle rollers. In this case, braking devices can be mounted above the spindle rollers.

The disadvantages of the described friction drive are heating and wear of the friction drive of the spindle, the inability to use the braking device when gearing the main drive.

The aim of the invention is to increase the durability of the drive.

To this end, the spindle drive of the cotton picker consists of gear rollers mounted on the spindles, interacting with gear arcuate tracks, with external and internal gearing, and means for synchronizing the position of the teeth located in the lead-in parts of the tracks, each gear track having a removable flat section mounted in the lead-in part of the track in front of the synchronization means, while on the working surface of the rollers, cylindrical rings whose outer diameter is equal to the outer diameter of the gear part of the roller, and longitudinal grooves are made on the gear tracks with a depth equal to the height of the teeth, with the possibility of placing cylindrical roller rings in them.

In FIG. 1 shows a general view of the drive: in FIG. 2 is a view along A in FIG. 1. in FIG. 3 is a section BB in FIG. 2; in FIG. 4 is a top view of the toe of the toothed belt (straightened); in FIG. 5 is a variant of collecting the volumetric flat part of the belt - allocation I in FIG. 4; in FIG. 6 is an end view of the removable part of the belt.

The spindle drive of the cotton picker consists of a toothed belt 1 straight and pads 2, which consists of a belt

and a spring-loaded rigid arcuate base of the reverse rotation of the spindles mounted on the spindles, rollers 3 having teeth 4 and cylindrical rings 5 evenly spaced along the height of the roller 3. The same teeth 6 and grooves 7 are made on the belt x 1, the height and configuration of the teeth and the groove of the belt 1 and roller 3 is according to fcetWiyidr. The working surface of the belt 1 is made of its layers: a hard, wear-resistant layer 8 and a soft, damping layer 9. In the inlet part of the belt 2 there is a flat part 10 for braking the rollers 3. After the flat part 10, the belt 1 teeth 6 are made with different heights - increasing with distance from the flat i-part 10 of the belt 2 to the zone of the belt 1, where the tooth 6 have a constant value. The flat part 10 of the belt 1 is connected to it by means of hooks of wires 11 with the help of a connecting rod 12. For close approximation, grooves 13 are made at the end to accommodate the hook of the connecting part of the belt 1. Belt 1 and shoe 2 are spring-loaded by means of a spring 14 and 15.

The drive operates as follows. When the drum rotates, the rollers 3 receive rotations from the belts 1 or 2, the gear drive provides a stable spindle speed. After disengaging, the roller 3 continues to inertia rotate in the same direction. In contact with the flat part 10 of the belt 1, the roller 3 decelerates. The low tooth height 6 at the beginning of the belt 1 provides a gradual shock-free start of the gearing of the gears 4 and 6. This is also facilitated by gearless cylindrical rings 5 and grooves 7. The latter also serves as an orientation gearing of the drive along the height of the roller 3: belt 1 due to the spring-loaded installation on the drum through the springs 14 and 15 can

vary in height. The double-layer belt provides wear resistance due to the presence of a wear-resistant layer 8 in the belt and the repayment of shock forces due to the presence of

the damping soft layer 9. When the braking plane of the belt part 1 or 2 is worn, it is easily removed by removing the rods 12 from the hooks of the wires 11, which are tightly placed in the grooves 13.

The technical and economic advantages of the drive are to increase its durability and improve agricultural performance due to the stability of rotation of the spindles.

Thus, the proposed drive provides reverse rotation of the spindles with a stable frequency due to gearing and durable operation due to the effective braking and synchronization of rotation of the spindles.
