VEESTAL

The invention relates to a stable for cattle, such as cows, pigs and the like, comprising a stable floor with at least one manure passage, as well as a sliding device movable over the manure passage for sliding manure out of the manure passage. It is noted that in the context of the invention manure also includes slurry and the like.

Such a cattle shed is known from French patent publication No. 2,718,606 (Massiot). The known stable comprises a stable floor with a manure passage provided with a longitudinal groove to guide the sliding device along it, so that manure present on the manure passage can be pushed away with the aid of the sliding device.

It is the object of the invention to propose an improved cattle shed 20, wherein the manure pass can be cleaned more efficiently than before, making use of a different technique.

To this end, a cattle shed of the type mentioned in the preamble according to the invention has the special feature that the manure passage comprises an elongated groove for sliding manure out of the manure passage, wherein the sliding device comprises a manure barge which extends at least partially obliquely to the groove, and wherein the manure barge extends at least substantially from the groove to a longitudinal edge of the manure passage. In practice it has been found that this makes a very efficient cleaning of the stable floor possible.

2

In a preferred embodiment of a cattle shed according to the invention, the manure barge extends over at least substantially half a width of the manure passage. The groove is therefore in the middle of the manure passage. This offers the possibility of cleaning the manure pass in, for example, two passages of the sliding device, one half of the manure pass being cleaned in each case.

In a further preferred embodiment of a cattle shed according to the invention, the manure slide is pivotable at least partially with respect to the sliding device in a plane parallel to the manure passage. In particular, outer parts of the manure slide are pivotable relative to the sliding device. This has the advantage that the manure walk in various passes can be cleaned via a reversing movement of the sliding device, wherein each time after a walk the manure slide is moved into a position in which it extends at least partially, namely with its outer parts, obliquely with respect to the groove.

In a further preferred embodiment of a cattle shed according to the invention, the sliding device forms part of an unmanned manure vehicle. The unmanned manure vehicle can preferably, after a first walk over the manure walk, make a reversing movement to subsequently make a second walk over the manure walk, wherein the manure slide can be moved from a first position, wherein the manure slide in the first walk run at least partially extends obliquely with respect to the groove, to a second position, wherein the manure scraper in the second pass extends at least partially obliquely with respect to the groove.

3

In a further preferred embodiment of a cattle shed according to the invention, the first and the second walkways each extend over at least substantially half a width of the manure passage.

In a further preferred embodiment of a cattle shed according to the invention, the groove is connected to a manure storage near one end thereof. In particular, the groove widens downwards, which results in a reduced ammonia emission in the shed.

The invention also relates to a sliding device for sliding manure from a stable floor into a groove apparently suitable for use in a cattle shed according to the invention.

The invention will be further elucidated on the basis of figures shown in a drawing, wherein - figure 1 represents a perspective and schematic view of a cattle shed according to the invention; figure 2 offers a perspective and schematic view of a sliding device as used in the cattle shed of figure 1.

Figure 1 shows a livestock shed 1 with upright walls 2, a roof 3 and a shed floor 4. The shed floor 4 comprises two tracks or manure passages 5, through which manure scrapers 6, to be further described below, move.

4

With reference to Figs. 2 to 6, each manure scraper 6 makes after a first run 7 over the half width of the manure run 5 (at the end thereof) a reverse movement to subsequently make a second run 8 over the half width of the manure run 5. During the reversing movement, outer parts A, B of the manure slide 6 are pivoted from a first position, wherein the outer parts A, B enclose an acute angle α, β in the first pass with a longitudinal groove running in the middle of the manure pass 5 9, to a second position, in which the outer parts A, B in the second path 8 also enclose an acute angle with the longitudinal groove 9. Optionally, the angles α and β are mutually equal and for instance 45 °. The manure scraper 6 is preferably part of an unmanned manure vehicle 10. Because of the oblique position of the outer parts A, B of the manure scraper 6, manure is effectively pushed from the runs 7,8 into the longitudinal groove 9. The longitudinal groove 9 is either open at the bottom, so that the manure pushed away is deposited in an underlying manure cellar, or closed at the bottom, so that manure moved away is transported to a manure storage 10 connected to the longitudinal groove 9, using a pump (not signed). A manure pit can also be used instead of a pump.

25

The manure scraper 6 is shown in detail in figures 3, 4 and 5. The outer parts A, B are pivotable relative to a straight part 11 of the manure slide 6 perpendicular to the longitudinal groove 9 about pivot axes 12, 13. 30

The invention is not limited to the embodiment shown, but also extends to other preferred variants that fall within the scope of the appended claims.
