Definitions

  • the invention is related to an animal shed system with an unloading area where a manure collecting vehicle can unload or dispose the manure.
  • the unloading area is provided as a floor opening in a shed floor, with a closing device to close the floor opening after unloading of the manure.
  • the invention relates to a closing device for such an animal shed system.
  • Wheeled manure-removal vehicles or manure robots are used in animal sheds to remove manure, i.e. feces and urine, from the animal shed floor. Removing manure from the shed floor gives cleaner floors and thus cleaner hooves of the cows or other animals held in the shed. This attributes to the health and well-being of the animals.
  • a manure-removing vehicle as described above is used in animal sheds that have to store a large quantity of manure, which forms an aggressive environment with toxic and flammable gasses. Such an environment is in need of extra safety measures to minimize the harm to the animals kept in the animal space, and any other users of the animal shed, such as a farmer.
  • European patent publication EP3932191 describes an animal shed system comprising an animal shed having an animal shed floor with a floor opening, and a reservoir situated under the animal shed floor. Through the floor opening manure can be dumped in the reservoir by a manure-removal vehicle.
  • a device extends from the floor opening into the reservoir and forms a passageway between the floor opening and the reservoir. The device is configured to prevent an airflow from the reservoir to the animal shed through the floor opening by blocking the passageway when in use.
  • the floor opening still needs additional safety measures such that animals and/or persons cannot accidentally step into the floor opening.
  • safety measures such as a safety structure, e.g. a safety cage, result in a reasonable sized area of the animal shed that is inaccessible to and therefore not usable for the farmer.
  • a safety cage limits the dimensions of the manureremoval vehicle to a maximum to prevent that the safety cage becomes too large and is therefore accessible by dairy animals or persons.
  • the floor opening has such dimensions that smaller farm animals, children or calves can accidentally end up in the reservoir, which can be fatal.
  • an animal shed system comprising
  • the animal shed floor has a first walking surface and an opposite second surface facing the reservoir, the first and second surfaces spaced apart, such that the floor has a thickness different from zero;
  • the closing device comprises an actuating system to move the closing device with respect to the floor opening to an open position opening up the floor opening or to a closed position closing the floor opening.
  • the closing device is provided at the floor opening to close the floor opening when the manure-removal vehicle is absent from the opening.
  • the closing device thus prevents that an animal and/or a person can accidentally step into the floor opening.
  • the closing device may form a safety structure like the safety cage described above, with the advantage that the area covered by the floor opening may be used in absence of the manure-removal vehicle. Additionally, the closing device in the closed position prevents any farm animal or person in the animal shed can accidentally step or slide into the reservoir.
  • the floor opening would be located in a corner of the shed, such that the area around the floor opening is also not accessible by the manure-removal vehicle. With the closing device closing the floor opening, the floor opening may be located at any desired location in the animal shed, for example a location that can be more easily cleaned and accessed by the manure-removal vehicle.
  • the animal shed floor may be a closed floor where the only opening to the reservoir or manure pit is the floor opening for dumping manure. Otherwise, the floor may be a permeable floor where urine and liquid feces can flow through drain holes to the reservoir or a separate part thereof, and solid feces remain on the first surface of the animal shed floor. With slatted floors and other floors comprising openings, less manure will be collected by the manure-removal vehicle.
  • the manure- removal vehicle may thus remove a mixture of feces and urine.
  • the manure-removal vehicle removes only feces that remains on the animal shed floor.
  • the animal shed is used for animal husbandry, in particular for cattle, such as dairy cows. Traditionally, cattle is kept in an animal space, such as the animal shed. Cattle, in particular cows, will excrete urine and feces that end up on the floor of the shed as manure (the mixture of urine and feces).
  • the manure-removal vehicle removes the manure and dumps the manure into the reservoir.
  • the manure-removal vehicle may be a wheeled manure-removal vehicle, such as an autonomous unmanned manure removal vehicle, e.g. a manure suction robot, or a pulled manure slide.
  • the manure-removal vehicle is preferably an autonomous unmanned manure removal vehicle that autonomously and unmanned drives over the animal shed floor and removes the manure from the animal shed floor.
  • dangerous gases may be released from the manure.
  • These gasses may include hydrogen sulfide, hydrogen cyanide, carbon dioxide, ammonia and methane. Peaks in concentration in the reservoir can result in fatal situations for humans and animals.
  • An additional aggravating feature is that these gases displace oxygen, which can result in a life-threatening situation.
  • some gases are flammable and may cause an explosion. Areas that pose extra danger are the confined spaces in the reservoir or manure cellar, but also the immediate surroundings such as the animal space.
  • Hydrogen sulfide is the greatest danger for humans and animals. When this gas is present in low concentration, it spreads an odor of rotten eggs. In high concentrations it is no longer perceived, because it paralyzes the olfactory nerve. This situation is when it becomes life threatening because death occurs immediately at a slightly higher concentration. Hydrogen sulfide is heavier than air, so it stays low to the ground. However, small animals like dogs or cats, but also small children are more likely to be caught by the gas.
  • HCN Gaseous hydrogen cyanide or prussic acid
  • Methane (CH4) is extremely flammable and can form explosive mixtures with air or other gasses. Methane is the most common gas formed from manure. It is lighter than air and is therefore usually at the top of the well or basement. It can explode very easily or give flash flames. A simple spark can be enough to cause a catastrophe. Methane can - if it occurs in large concentrations - also expel the oxygen from an environment and indirectly lead to suffocation, certainly because it often occurs together with carbon dioxide that can also have a choking effect.
  • Carbon dioxide is formed during the decomposition or combustion of organic matter in an atmosphere with oxygen. It is also one of the main components of biogas. Carbon dioxide is particularly dangerous when it occurs in high concentrations. It is an odorless gas and is therefore sometimes called the silent killer. It often occurs together with carbon monoxide (CO). Carbon monoxide is very toxic because it replaces oxygen in the red blood cells. Carbon dioxide is less of a problem gas in the context of manure gases, unless in the manure pit itself. In the animal shed, it is usually diluted quickly. Because the gas is heavier than air, it can accumulate in the manure cellar, even if it has been empty for a while.
  • Ammonia (NH3) is formed during the breakdown of nitrogen-rich compounds (proteins and urine). It is lighter than air and usually evaporates fairly quickly. It is therefore also one of the gases that can cause a lot of odor nuisance in an animal shed or barn. At low concentrations, it irritates eyes and mucous membranes. In higher concentrations, it can be fatal. Because of the strong pungent odor, ammonia is easily perceived so that measures can be taken in time, for example by ventilation.
  • the closing device is configured to prevent an airflow from the reservoir to the animal shed through the floor opening when in use.
  • the closing device is moved to the open position by the actuating system only upon arrival or presence of the manure-removal vehicle at the floor opening.
  • the animal shed system may comprise a detection system.
  • the detection system may comprise a sensor system to sense the presence of the manure-removal vehicle, such as a magnet sensor, or a mechanical detection system to mechanically detect the presence of the manure-removal vehicle, such as a lever or button in the animal shed floor, or the like.
  • the detection system may be communicatively connected to the control system.
  • the manure-removal vehicle may be provided with a detection device to detect its presence at the deposition opening, wherein the detection device may be communicatively connected to the control system.
  • the detection device may be part of the detection system described above.

  • the closing device is only to be opened when the manure-removal vehicle has arrived and/or is present at the floor opening, and closed when the manure removal vehicle is absent from the floor opening.
  • the manure-removal vehicle can only move away from the floor opening, i.e. remove itself from the floor opening, when the closing device is in the closed opening, i.e. the floor opening is closed and covered.

  • the actuating system is located underneath the animal shed floor, and wherein the closing device is actuated to move with respect to the floor opening towards the reservoir.
  • the actuating system can be placed underneath the animal shed floor, or at least below the level of the animal shed floor, for instance within the closing device itself. In that way, the closing device may enclose and shield the actuating system.
  • the closing device may move in different manners, for instance in a sliding motion with respect to the floor opening, in rotational motion with respect to the floor opening, or a tumbling motion with respect to the floor opening.
