Abstract

A wheeled manure-removal vehicle for removing manure from an animal-shed floor includes a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor. The scraper assembly includes a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body. The rolling body extends on a side of the scraping element which faces away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together, and has, on the side facing the scraping element, a rolling surface which is convexly rounded towards the scraping element. The use of the rolling body for contact with the scraping element has an advantageous effect on the life of the scraping element on the vehicle.

First claim

The invention claimed is:

1. A wheeled manure-removal vehicle for removing manure from an animal-shed floor, the vehicle being provided with a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor,
wherein the scraper assembly comprises a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body,
wherein the rolling body extends on a side of the scraping element turned away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together, and
wherein the rolling body, on the side facing the scraping element, has a rolling surface which is convexly rounded towards the scraping element,
wherein the rolling body has a substantially semicircular shape in cross section on a side thereof facing the scraping element.

2. The vehicle as claimed in claim 1 , wherein the scraping element is curved in a longitudinal direction thereof, and wherein the rolling surface is also curved in a longitudinal direction of the rolling body.

3. The vehicle as claimed in claim 1 , wherein the rolling body comprises an elongate body.

4. A wheeled manure-removal vehicle for removing manure from an animal-shed floor, the vehicle being provided with a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor,
wherein the scraper assembly comprises a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body,
wherein the rolling body extends on a side of the scraping element turned away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together,
wherein the rolling body, on the side facing the scraping element, has a rolling surface which is convexly rounded towards the scraping element, and
wherein the vehicle comprises a holding strip designed to form a holder for the scraping element in combination with the rolling body, wherein part of the scraping element is clamped between the rolling body and the holding strip.

5. The vehicle as claimed in claim 4 , wherein the rolling body, the scraping element and the holding strip are attached to each other using a fastener extending between the rolling body and the holding strip, through the scraping element.

6. The vehicle as claimed in claim 4 , wherein a bottom edge of the holding strip is rounded.

7. A wheeled manure-removal vehicle for removing manure from an animal-shed floor, the vehicle being provided with a scraper assembly for scraping the manure together into a manure-storage space by scraping across the animal-shed floor,
wherein the scraper assembly comprises a flexible, strip-shaped scraping element which is partly arranged around the manure-storage space and a rolling body,
wherein the rolling body extends on a side of the scraping element turned away from the manure-storage space in order to be in contact with the scraping element at least while scraping the manure together,
wherein the rolling body, on the side facing the scraping element, has a rolling surface which is convexly rounded towards the scraping element, and
wherein the vehicle comprises:
a tank for manure storage;
a plate fitted under the tank and provided with a manure passage opening for allowing manure to pass from and to the tank at the location of the manure-storage space; and
a suction nozzle element attached to the plate at the location of the periphery of the manure passage opening, the suction nozzle element being in the shape of a short hollow tube segment extending through the plate in a downward direction.

8. The vehicle as claimed in claim 7 , wherein the rolling body is attached to the plate, at a position which is, viewed in the direction of travel of the vehicle, situated behind the manure passage opening.

9. The vehicle as claimed in claim 7 , further comprising a holder for the suction nozzle element, the holder being attached to the plate and extending at the location of the periphery of the manure passage opening,
wherein part of the suction nozzle element is accommodated in the holder and attached to the holder,
wherein the holder comprises an assembly of two annular holder elements, and
wherein each holder element has a first part extending in the plane of the plate, and a second part integrally connected to the first part and extending through the plate and bent in a downward direction with respect to the first part.

10. The vehicle as claimed in claim 9 , wherein the first parts of the holder elements are attached to each other, and wherein the second parts of the holder elements are at a distance from each other and hold the part of the suction nozzle element therebetween.

11. The vehicle as claimed in claim 9 , wherein material is arranged on the holder, on an upper side of the plate and the holder for the suction nozzle element, the material serving to seal the suction nozzle element, as accommodated in the holder against the tank of the vehicle.

12. The vehicle as claimed in claim 7 , wherein a dimension of the plate is sufficient to have free access to a part of the plate on two sides of the vehicle.

13. The vehicle as claimed in claim 1 , wherein the vehicle is self-propelled.

14. An assembly of a plate with a manure passage opening, a suction nozzle element attached to the plate at the location of the periphery of the manure passage opening, and a combination of a scraping element and a rolling body attached to the plate and extending along the scraping element, for fitting underneath the tank of the vehicle as claimed in claim 7 .

15. The vehicle as claimed in claim 1 , wherein the scraping element is curved in a longitudinal direction thereof, and wherein the rolling surface is also curved in a longitudinal direction of the rolling body, substantially parallel to the scraping element.

16. The vehicle as claimed in claim 1 , wherein the rolling body comprises an elongate body having a substantially circular outer periphery.

17. The vehicle as claimed in claim 7 , wherein a dimension of the plate is sufficient to have free access to a part of the plate on two sides of the vehicle, the part of the plate serving to attach the plate to the vehicle.

18. The vehicle as claimed in claim 2 , wherein the rolling body comprises an elongate body.

19. The vehicle as claimed in claim 1 , wherein the scraping element is located rearwardly of the manure-storage space, and wherein the scraping element is curved in a longitudinal direction thereof.
