BRUSH PLANE OF CLOTHING AND COTTON-CLEANING MACHINES REMOVERS

one

The invention relates to the field of agricultural engineering, in particular to cotton harvesting pullers.

Known stitched strips pullers cotton and cotton ginning machines, containing, their U-shaped clip, the bar, inserted into the throat of the clip and the locking element in the form of a rod.

Odiaco in such w, light bars rod, located in the profile chamber of the holder along its length, deprives the brush of possible deformations in the process of work, causing those the most enhanced wear. In addition, the application of a rod as a fixing element tightens tolerances on the transverse and longitudinal dimensions, which is dictated by the assembly conditions. This complicates the fabrication technology of the bar.

The aim of the invention is to increase the durability and reduce the complexity in the manufacture and repair of w, flowing nanki.

This is achieved by the fact that the locking element is polypropylene in the form of a cylindrical helix installed in the cage, the outer diameter of which exceeds the width of the throat of the cage, and the coils of the helix are embedded between the threads at the bottom of the brush.

FIG. 1 shows the proposed brush strip, the locking element of which is made in the form of a coil spring and is located in sections along the length of the clip, in the places of embroideries; FIG. 2 is a sectional view of the casing of FIG. 1, in the place of absence of stamping; in fig. 3 - the same, in the place of stamping; on

FIG. -1 - fixing element - spiral spring; in fig. 5 - a brush strip, in which the length of the locking element (coil spring) is equal to the length of the clip; in fig. 6 is a cross section of the strip in FIG. five,

in the place of absence of punching (crimping of the barrel at the base of the brush element was not performed; pa of Fig. 7 is the same, at the site of punching. In (7-piece holder 1 having a section

along the length with the stamps, which serve as seats when fastening the cage in the separators, the brush elements 2 are inserted (without thickening at the base) with a coil spring (or springs) 3, which serves as a clamp of the brush in the cage.

In the case of the brush strip, as shown in pa FIG. 1, having clamps only in the places of stamping, the sleeve 1 after assembly is crimped at the base of the brush

element to the cross section shown in FIG. Thus, the fixing of the brush in the cage at the portions of the stamps is carried out by the coil springs 3, and in places where no stamping is present, by the shape of the cage obtained during the crimping.

In the case of a brush strip, as shown in FIG. 5, the fixing of the brush 2 in the casing 1 is carried out by a spiral spring 3, the length of which is equal to the length of the casing 1. Additional fixing of the brush member is not performed by crimping the casing. The locking element 3 in both cases is located in the volume of the profile chamber of the yoke 1, above the point of attachment of the threads in the brush element, with the introduction of turns of the spirals between the threads of the brush. In both cases, the condition d b is met, where d is the outer diameter of the spring; b - the transverse throat size.

In the case of the brush strip shown in FIG. 1 met condition

where / is the length of the vyshtampovki holder;

L is the length of the fixing element of the brush strip.

Subject invention

A brush strip for cotton pickers and cotton gin makers, containing a Y-shaped clip, a brush inserted into the mouth of the clip, and a fixing element, in order to increase durability and reduce labor intensity during manufacture and repair, the fixing element is designed as a cage of a cylindrical helix, the outer diameter of which exceeds the width of the throat of the cage, and the turns of the helix are embedded between cheats at the bottom of the brush.
