Abstract

The invention relates to the textile industry, can be used in saw gins, and allows for improved reliability by creating conditions for better capture of fibers by saws. The grate contains fixed grate mounted on support bars x installed relative to each other with a gap between their side surfaces to pass the saw cylinder. On the upper working surface of each grate, a wedge-shaped protrusion is made, the top of which is offset to one of the side surfaces of the grate, and one of the sides of the protrusion coincides with this surface. The bevels formed on the working surface of the grates have opposite directions in each pair, which contributes to a more efficient reorientation of cotton seeds located between adjacent saws. 1 hp f-ly, 3 ill.

The grille contains fixed grate bars supporting each other with a gap between their side surfaces for the passage of the saw cylinder. On the upper working surface of each grate, a wedge-shaped protrusion is made, the top of which is displaced to one of the side surfaces of the grate, and one of the sides of the protrusion coincides with this surface. The bevels formed at this time on the working surface of the grates have opposite directions in each pair, which contributes to a more effective reorientation of cotton seeds located between adjacent saws. 1 hp f-ly, 3 ill.

The invention relates to the textile industry and can be used in saw gins.

The purpose of the invention is to improve reliability by creating yc no BVsA for better capture of the fibers by saws.

FIG. 1 shows the grate of the saw gin-saw; FIG. 2 shows section A-A in FIG. 1-, FIG. 3 - the same, the variant of execution of the working surface of the grate.

The grate of saw gin contains the upper 1 and lower 2 grate bars. To these bars, the grate 3 is fixed with a pitch of their location corresponding to the pitch of the circular saws 4 of the saw cylinder and with a gap between their side surfaces for the passage of the saws. On the upper working surface of each grate there is a protrusion, one side of which coincides with the side surface of the grate, and the inclined working surfaces of the adjacent grate have opposite directions, for which the specified sides of the protrusions on the adjacent pit are symmetrically relative to the plane of the saws 4. .

The working surface of each grate can be made curvilinear of two adjacent and concave and concave portions (Fig. 3), and the adjacent working surfaces: e

ny grates in their cross section form parabolas: upper part-; The half of the parabola is convex, the lower part - half of the parabola is concave.

In the process of operation, the cotton raw pellets pick up the teeth of the saws 4 and transport them into the working area of the grates 3, where the fly slows down and part of the rolo con (fiber fiber strand) comes off. Full elimination of all the fibers from the seed occurs during repeated approach of the bat to the saw and their interaction in the working area.

When the tip of the protrusion moves to one of the side surfaces of the grate in each pair of adjacent grates relative to the saw level, protrusions and depressions are formed, which contributes to a more efficient reorientation of cotton flail on the saws in the process of their interaction with the saw the grate from the tip of the protrusion to the saw is not enough for an effective process of reorientation (turning over) of the seed cotton, and in the proposed one this distance S is twice as large a capture of additional fibers, which leads to a more efficient ginning ipovysheniyu gin reliability in operation,

Claims (1)

The implementation of the upper working surface of the parabolic grate creates good conditions for the capture of fibers due to the shear of the blades to the saws, and besides, due to the curvilineariness of the working surfaces, the force of the seed blow on the grate is reduced and their damage is eliminated. Invention Formula 1, a grate-sawn grate, containing grate bars, mounted on supporting bars with a bearing, one relative to another between their side surfaces for the passage of circular saw blades and having protrusions along their upper working surface, characterized in that To increase the reliability of the operation by creating conditions for better capture of the fibers by saws, the protrusion on each grate is made in such a way that one of its sides coincides with the side surface of the grate, and in each yar of the adjacent grate Oron vg Stupa arranged symmetrically with respect to the plane of arrangement of the saw blade, 2, Lattice according to claim 1, characterized in that the working surface of each grid-bar is made curved from the concave and concave portions interconnected, and the working surfaces of adjacent bars and cross-sections form parabolas in their cross section.
