Title:

Grating for grating.

Utility model

The innovation "concerns a grating for Rostauf stall, esp. to cover a flume "in alluvial manure systems, the longitudinal rods of which rest on cross members. With known rusts

/ One of these types are the longitudinal bars of, for example, 1 m in length Number carried by cross members. This large number of cross members makes it difficult to clean the grate, as the openings allow them to fall through of the droppings are in the form of rather short rectangles.

The purpose of the furnace is to remedy this disadvantage, and consists in the fact that cross members are only at the ends of the, for example, about 1 m long Grate are provided.

Mostly it is preferred to have the grate on the long sides with support bars to be provided, by means of which it rests on the edges of the flume. Although it is also possible both of them To let the cross member according to the invention rest directly on the edges of the flume, the arrangement of longitudinal Support rods are preferred, which according to the invention are combined with the two cross members to form a rigid frame.

Since the longitudinal beams according to the invention are only arranged at the ends of the grate, so for example. At a distance of 1 m, the

-2-

The unsupported length of the longitudinal bars is almost the same. That's why According to the innovation, the longitudinal bars receive a cross-section with a high section modulus in the vertical and horizontal directions offers, for example, a T-shape, a semicircular shape or a trapezoidal shape. A large moment of resistance is also necessary in the horizontal direction, as the lier is often strong horizontal when standing up Exercise ß-rafts on the grate bars. When the section modulus the grate bars for this cannot be estimated with certainty in advance If the force is not sufficient, the longitudinal bars can be replaced by one or more non-load-bearing cross bars, e.g. with a round cross-section, be kept at a distance, which are welded or caulked to the longitudinal bars and preferably below the center of the Longitudinal bar cross-section should be provided so that the grate can be easily cleaned from above.

The inflation is explained on the basis of the drawing examples. It demonstrate

! ig. 1 a grate according to the innovation according to I-I of! Ig. 2,

Mg. 2 the top view of the grate according to Pig. 1 but in half scale and

Fig. 3 to 7 cross sections through different grate bars.

The grate according to the S ¹ Ig. 1 and 2 has transverse grate bars 1., which in the present case all have the shape of a trapezoid, the larger side of which is at the bottom. These grate bars rest with each end 1a on a cross member 2, which is designed as a simple square iron. The two ends of the! Iron 2

are welded at 3 to a support rod 4, which has the shape of an upside-down U. Other porms for the ¹

/are
Bearing rods ^ of course also possible. The grate bars 1 thus carry freely along their length and therefore preferably have a profile that is adapted to this load, as is the case with the Pig. 3 to 7 is explained.

Pig. 3 shows a profile, the cross-section of which is from an overhead Trapezoid 5 with attached web 6 below. Roughly in the middle of the grate length, the web 6 is provided with a hole 7, through which a round iron 8 is inserted. This round iron sits below the horizontal center plane of the profile and goes through all grate bars. The round iron is welded or caulked at points 9 so that it is horizontal Forces that are exerted on the grate bars and can lead to its sagging, transferred to the neighboring grate bars.

The profile according to Pig. 4 consists of a semicircle 1o with below applied splash 11. The profile according to Pig. 5 has an approximate triangular cross-section with a triangle on its tip. The profile according to Pig. 6 again has the cross-section of a trapezoid 12 with the web 13 attached at the bottom, with the large side of the trapezoid on top. The rust bar according to Pig. 7 has a cross section in T-shape. In all cases, the underlying edges 14 are made sharp in order to make it easier for the manure to slide off.

The overhead edges 15 are strongly rounded to avoid injuries to prevent animals.
