SU1752262A1 - Spindle drum of cotton picker - Google Patents

Abstract

Use: vertical spindle cotton harvesting machines. The essence of the invention: the protrusion of the gland cylinder is provided with an elastic element. The elastic element is located on the side opposite to the direction of rotation of the spindle, and is directed in its direction. There is a gap between the elastic element and the spindle. 2 Il.

Description

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

Known vertical spindle drum cotton picker containing spindles and gland cylinder

with protrusions on the outer surface. In order to increase the completeness of the cotton harvest, the protrusions on the outer surface of the gland cylinder are arranged along a helix.

The disadvantage is that the protrusions on the gland drum do not affect the entire height of each spindle, i.e. they do not contribute to better pinning of the trapped cotton on the teeth of the spindles, thereby not reducing the loss of raw cotton from carrying and the loss to the ground.

A spindle drum of a cotton picker is known, containing two disks mounted on a vertical shaft with supports located on their periphery with vertical spindles placed between the protrusions of a corrugated gland cylinder fixed on

the discs are parallel to the shaft and means for creating a directional air flow in the form of a cylindrical distribution chamber, at the bottom of which holes are made communicating with vertical tubes in the protrusions of the gland cylinder.

A disadvantage of the known cotton harvesting drum (prototype) is low operating efficiency, since the air flow does not help keep cotton on the spindle surface, and it is also very difficult to ensure tightness between the rotating and stationary parts of the system.

The purpose of the invention is to increase the completeness of the collection and reduce the loss of cotton on the ground

The goal is achieved by the fact that elastic elements placed with a gap relative to the spindles are installed on the movable cylinder of the spindle drum in the area of the projections along their entire height from the side opposite to the direction of rotation of the spindle drum.

FIG. 1 shows the spindle drum of the cotton harvester in FIG. 2 - the same, in section.

The cotton-picking drum contains two disks 2 mounted on a vertical shaft 1 with supports located on their periphery with vertical spindles 3 placed between the projections of a corrugated pressing cylinder 4 on which elastic elements 5 are mounted and fixed on disks 2. parallel to the shaft one.

The device works as follows.

In the working area, when cotton is taken from the opened bolls, spindles 3 rotate teeth towards elastic elements 5, which, in contact with the fiber, fix it on the teeth of spindles, preventing the trapped cotton from falling off. spindles, as the spindles rotate the teeth in the opposite direction. As a result, significantly reduced

cotton is carried by the pressing cylinder and spindles into the work area where it falls to the ground. Thus, the installation on the protrusions of the gland cylinders elastic

elements helps to improve the completeness of the collection of cotton in the bunker and reduce its losses to the ground. Elastic elements can be made of bristle, polymer fishing line, rubber, etc.
