Abstract

Usage: vertically spindle cotton pickers. SUMMARY OF THE INVENTION: In the disks 2 and 3, spring-loaded leads 9 are arranged along a sliding fit, the upper part of which is connected to the profiled track 6 by means of rollers 10, and the lower - to the lower support 16 of the spindle 13. The upper support of the spindle is mounted on a sliding fit in the upper disk 2 having a U-shaped cover with a screw 14 of the kinematic pair of screw-nut spindle 13. The second drive 3 is mounted in the lower disk 3 and is rigidly connected to the first. 1 s P. f-ly, 2 ill. V;

Description

The invention relates to agricultural machinery.

The purpose of the invention is to increase operating efficiency, ease of installation, maintenance and reduction of energy consumption; improving the grip conditions of cotton by providing vertical movement of the spindle in the working slot.

The goal is achieved in that in the spindle drum of a cotton picker comprising a drive shaft with upper and lower disks rigidly connected to it, placed in supports, drive elements of the spindles mounted. on the upper support, rigidly fixed to the frame of the cotton picker, connected to the spindles and leashes by means of rollers, ensuring their vertical movement, the upper and lower disks have guide holes for accommodating the leashes, while the spindles are made in the upper part with an inner threaded elements and with the possibility of longitudinal movement relative to the axis of the fixed screws rigidly connected to the upper disk, leading them to rotate in all areas of work.

In FIG. 1 schematically shows a spindle drum of a cotton picker, section; FIG. 2 is a section AA in FIG. 1.

The spindle drum of the cotton picker comprises a vertical shaft 1 on which the horizontal upper 2 and lower 3 discs are rigidly fixed. The shaft 1 is mounted in bearings 4 at the same time with the upper support of the drum 5, to which the guide 6 is fixedly mounted in the form of a treadmill. The upper 2nd lower 3 discs have guide holes 7 and 8 for accommodating the leads 9, provided with rollers 10, which are connected to the upper part 11 of the lead, preloaded by the spring 12.

The vertical spindles 13 are mounted on the axes of the drive elements 14, made in the form of fixed screws, with the possibility of reversible rotation and are placed in the supports 15 of the upper disk 2 and the leads, respectively. The spindles 13 are mounted for longitudinal movement relative to the axes of the drive elements and the lower support 16 is connected to the lower part of the leads.

A cell 17 is attached to the leash in the form of a vertical groove spanning the spindle. The lower part of the leash is provided with a runner 18 and a second shoulder 19.

When the cotton picker is operating, the spindle drum, along with the translational (together with the machine) movement, rotates around its axis by a shaft 1, which is driven by drive elements of the cotton picker. At

this spindle 13 together with a leash under the pressure of the rollers 10 through the springs 12 occupies a lower position when approaching the working area; its position is determined by the position of the roller 10 relative to the treadmill 6, as well as the runner 18, which rests on the soil and slides along its surface.

When lowering the internal threaded elements in the upper part of the spindle together with the carrier-lead along the screw axis, the spindles are driven together with the threaded elements 14, along with the translational movement, into the rotational around

of its own axis, while the spindle rotates its teeth forward and grabs them with raw cotton from the opened bunches of the cotton bush, including from the low located bolls, and, winding

removes them from the working area of cotton picking.

As the spindle drum rotates around its axis, the movable section with the spindle moves towards the zone

removal, and when leaving the working area, the roller 10, rolling over the surface of the treadmill b, raises the section to the upper position when approaching the removal zone from the spindles. Consequently, the spindle starts

rotate in the opposite direction. The puller removes cotton from the spindles, feeds it into the receiving chamber, from where it is transported to the hopper of the machine.

With this design spindle

drum spindles have the ability to descend to low open cotton bolls and grab them; the spindle drive is passive, but rigid, ensuring

stable established kinematic modes of operation of the spindles, while their reversal occurs smoothly with any desired acceleration.

The use of the proposed spindle drum ensures the efficiency of the cotton picker and increases the completeness of collection by picking cotton from low-lying boxes and

ensuring stable established optimal kinematic modes of operation of the spindles. As a result, the efficiency of the drum in operation is increased, its assembly, maintenance and energy saving are improved.

Claims (1)

SUMMARY OF THE INVENTION 1. Spindle drum of a cotton picker comprising upper and lower disks mounted on a shaft spindles with a kinematic screw-nut pair installed between disks, a profiled track above the upper disk interacting with a spring-loaded roller, characterized in that, in order to improve conditions grip cotton lobes by ensuring vertical movement of the spindle in the working slot, spring-loaded leashes are placed in disks along a sliding fit, the upper part 0 which are connected to the profiled track by means of rollers, and the lower - to the lower support of the spindle, the upper support of the spindle made in the form of a nut and mounted on a sliding fit on the upper disk having a U-shaped cover on which the kinematic pair screw is fixed. 2fDrum according to claim 1, with the exception of the fact that, in order to prevent the spindle from turning around the axis of the leash, a second leash is installed in the lower disk, which is rigidly connected to the first.
