SU28373A1 - The working body of the cotton harvester - Google Patents

Description

The invention relates to cotton picker bodies made in the form of a rotating spindle with a screw thread. B. The proposed working body, to prevent winding of cotton from the bushes on the spindle, is surrounded by a fixed frame consisting of a bottom and a head connected by rods tightly adjacent to the screw cutting of the spindle, along which the cotton crests of the screw are moved to the assembled drum.

In a modification of the working body of the fixed frame is made in the form of a spiral, covering the spindle; the latter can be hollow with the infinite installed along the spindle and covering its walls, supplied with needles, tapes, which receive movement from the friction of the cotton seized by the needles of cotton on a fixed helix covering the spindle.

In FIG. 1 shows a longitudinal section of the working body of a cotton harvester; FIG. .2 cross-section of it; FIG. 3-modification of the working body; 4 is a cross-section of it; FIG. 5-modification of the working body with longitudinal teeth; FIG. 6- cross section of it; FIG. 7 is a longitudinal section of the hollow spindle; FIG. 8- cross section of it.

The working body of the cotton harvesting machine consists of a spindle 2 rotating about its axis 2 (Fig. 1, 2), equipped with a screw thread 3, surrounded by a fixed casing formed by the bottom and a head 7 connected by rods 1, which can rotate around its axis and tightly fit ridge of conical or cylindrical thread 3. with slightly corrugated grooves.

When a rotating spindle is inserted into the cotton bush, cotton is caught by the screw surface of the spindle in the spaces between the rods 1, preventing the winding of the cotton spindle, the screw crests of which move the cotton along the rods, which then enters the assembly drum b. ,,

In a modification of the working body of the cotton harvesting machines shown in FIG. 3, 5 and 7, the rotating spindle 8 is placed in a fixed frame that covers it, made in the form of a spiral 9. The spindle is provided with a small notch or protrusions 10 (Fig. 4), which reach up to approx. On the collecting drum 16. The spindle winds itself cotton fiber, which thanks to sleep. The rails 9 are fed into the collecting drum 16. On the spindle shown in FIG. 5, 6, a notch is made on the faces of the longitudinal axes 11, the teeth directed toward the base of the spindle.

In the embodiment of the working body shown in FIG. 7, 8, the spindle 14 is made hollow, and through the slots 15, endless ribbons 12 are mounted along it, carrying needles 13 and enclosing the spindle walls. The needles 13., during the rotation of the spindles, seize the cotton, due to the friction of which the fixed spiral 9 of the tape 12 receive movement along the arrow o, and the needled cotton is fed inside the spindle and from there into the collecting drum.
