Description

[Detailed description of the invention] This invention relates to floor grates for use in pigpens, cowsheds, and other livestock barns.

Maintaining the hygiene of livestock barns is important for the health management of livestock, but it is particularly important to ensure that there is no excrement or urine on the floor.

Therefore, there is a tendency to use slatted flooring for the floors of livestock barns, but this has the disadvantage that highly sticky droppings stick to the sides of the vertical slatted bars and do not fall, resulting in clogging.

In order to solve this problem, for example,
As described in Publication No. 3, as shown in FIG. 1 as a longitudinal sectional front view of an example of the crosspiece 1, the side surface 1A of the crosspiece is inclined so as to approach the center of the width of the crosspiece as it goes downward. However, unless the angle of inclination is made considerably large, the tendency for the feces 2 to stick to the surface without falling completely will not disappear.

However, if the angle of inclination is increased to the extent that the dung can be easily cut, the thickness of the upper part of the side surface of the crosspiece will decrease and it will no longer be able to support the weight of the livestock.

Based on the above-mentioned viewpoint, the present invention provides a grating for the floor of a livestock barn that allows dung to be cut off easily without reducing the strength of the crosspiece, and has a grating that is orthogonal to both end edges 5, 5. The upper steeply sloped surface 4 has both sides of the crosspiece 4 approximately half the thickness of the crosspiece.
A, and an intermediate gently sloped surface 4C having an extremely large inclination angle from the lower end of the upper steeply sloped surface 4A to the upper steeply sloped surface 4A.
and a lower steeply sloped surface 4B following the lower end of the gently sloped surface 4C, and the cross-sectional shape of the crosspiece 4 is a substantially inverted convex shape with both sides bent.

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in a perspective view in FIG.
It consists of edge portions 5, 5, a central connecting portion 6, etc., and the crosspiece portions 4, 4 are perpendicular to both end edge portions 5, 5.

As shown in FIG. 3, which is an enlarged sectional view taken along the line III-III in FIG.
A, a lower steeply sloped surface 4B, and a middle gently sloped surface 4C, and the cross-sectional side surface shape of the crosspiece 4 is formed into a broken line shape.

The upper steeply inclined surface 4A and the lower steeply inclined surface 4B have a height approximately equal to the thickness of the crosspiece 4, and are connected by an intermediate gently inclined surface 4C having a very large inclination angle.

As shown in FIG. 4, which is an enlarged cross-sectional view taken along the line IV-IV in FIG. This is a part that is placed on a raised part of a concrete tank-like underfloor structure of a livestock barn (not shown).

In this embodiment, two crosspieces 4 are used, and a plurality of crosspieces are used as shown in the plan view in FIG. 5, but the number of crosspieces 4 may be one or three or more.

Also, reinforced concrete may be used instead of prestressed concrete.

Since the present invention is configured as described above, when the excrement excreted on the crosspieces 4, 4 sinks into the gap between the crosspieces 4, 4, the upper layer having a height of approximately Even if attached to the steeply sloped surface 4A, the intermediate gently sloped surface 4C has an extremely large slope angle.
The feces easily fall off at the ridgeline between the two, and the gap between the crosspieces 4, 4 will not be clogged.

In addition, the present grates 3 in which the side surfaces of the crosspiece are formed by the upper steeply sloped surface 4A, the intermediate gently sloped surface 4C1, and the lower step slope 4B are the crosspieces 4, 4.
There is no reduction in strength, especially bending strength.

As is clear from the above explanation, the proposed grates can be used as floorboards for livestock barn floors, especially those with a water-washing structure under the floor, to avoid clogging with feces, and provide strong, durable, and sanitary livestock barns. It has advantages such as being effective at humping.
