Description

The invention relates to a pen for littering and rearing piglets, comprising a metal structural unit defined by side walls, comprising a sow stand with at least one opening wall, a sow feeding trough or piglet feeding trough, feed storage tanks and a supporting structure of interconnected floor elements, attached to the legs of the metal structural unit and forming a raised floor.

Various stalls for raising piglets with a raised floor, the so-called slatted floor, are known from practice, in which stalls for sows divide the basic area of the stall into two or three parts. .

The sow stalls are usually connected to the short sides of the piglet stalls or are arranged in an inclined line (diagonal) of the stall. In addition to restricting the movement of sows in the closed position, the sows 'stalls also increase the strength of the interconnected elements, but just under the greatest stress, ie for blowing and settling sows, sows' stalls cannot fulfill their function, as one or two sides are open structures. Due to this, the interconnecting structural elements are oversized in order to reduce the damage to the pen or their reinforcement is larger than necessary, which increases the weight and material consumption per pen.

There are also known stands for rearing piglets with a removable side wall, in which the removable sides can only meet the requirement of increased load-bearing capacity by using special, relatively easy-to-release fasteners. Proper mounting of these fasteners is sometimes problematic, as they are often lost due to their mobile nature, thus reducing the stiffening effect of the removable side, so that other load-bearing elements are exposed to increased stress and durability and ultimately reduce stand life.

A common feature of standing with the most diverse floor elements is that the floor elements lie on various load-bearing structures in such a way that they are stressed mainly in the vertical direction under load, so that they also bend in the vertical direction.

The load-bearing structure must therefore balance the forces in the floor plane or in the plane parallel to the floor in order to apply a direct load, as a result of which, however, the material consumption increases, since the floor elements have to withstand forces parallel to the floor.

The lateral load-bearing capacity of load-bearing elements on which a vertical load acts is increased either by a suitable □ movement of the load-bearing element or by the use of a special material. Both methods increase the consumption of material or the cost of labor required for production, notwithstanding the fact that the total cost of producing the pen increases.

The use of a removable feeding trough for sows is also known. So far, two solutions have been used to strengthen it. Either the feeding trough for sows is guided at the top on a tube with a circular cross-section and secured at the bottom against tilting at the feeding place by a sliding rail attached to the floor, or the guide tube is replaced by a so-called closed profile with square or rectangular cross-section. guide tubes. This achieves an advantage at the feeding point, but has the disadvantage of moving the feed trough from the feeding point, since it is not possible to pour out the cleaning water when cleaning the feed trough, which causes cleaning difficulties and makes cleaning more laborious.

It is also known to those skilled in the art that the course of the litter and rearing of piglets is monitored and registered. For this purpose, pre-printed so-called registration sheets are used, which are placed in a barn above a row of stands on a special structure or are hung on a holder or use wooden or metal boards, which are both expensive and difficult to operate due to their arrangement. at work, they even pose a risk of injury.

The object of the invention is to construct a pen for the litter and rearing of piglets free from the disadvantages and shortcomings of the known solutions from the point of view of material consumption, which, however, would have the desired mechanical strength and rigidity even when the stall is opened for sows. By designing the pen according to the invention, it is also intended to facilitate the work of the operator by various design variations in order to create favorable conditions for durability and provide the possibility to record piglets and piglets without the need for various aids outside the pen.

The stated task is achieved in a pen for litter and rearing piglets consisting of a metal structural unit delimited by side walls, comprising a sow stand with at least one opening wall, a sow feeding trough or piglet feeding trough, feed storage tanks and supporting structure of interconnected floor elements. , fixed to the legs of a metal structural unit and forming a raised floor, the essence of which consists in that mutually parallel longitudinal beams, to which side opening walls are connected and which are formed by inclined web plates, alternately inclined to each other and deviated from each other , welded between the connecting plates and at least one further beam arranged in the sowing space, most suitably in the pen axis below the floor elements, also formed of inclined web plates alternately inclined and deviated from the vertical plane and welded between the connecting plates.

The floor elements are formed of supporting tiles placed side by side, reinforced along the edges by downwardly bent edges, the downwardly bent edges of two parallel shorter adjacent edges being connected by a connecting plate of each longitudinal beam and forming a force transmission plane parallel to the ground and standing frame fronts. for sows, they are connected by at least one fixed upper switching element, with which they form a rigid three-dimensional frame structure. ’

The sow house is provided with a longitudinally adjustable limiter, at least one expansion limiter, displaceably connected to the switching elements, an opening and removable door located on one front and a second removable door on the other front, a side wall fixed along the longitudinal sides of the stall and another side opening wall provided with a locking pin. The side opening wall consists of a removable wall panel provided with connecting hooks for connecting the connecting elements to the corresponding longitudinal beam of the floor structure supporting structure and on both sides from above with legs and a fastening member formed by a locking pin passing through holes in the legs and provided with a cam against accidental displacement.

A feeding trough is located in the sows 'stall, the linear displacement of which is defined by a limiter between the first end position inside the sows' stall and the second end position outside the sows 'stall along a guide with two guide sections, the cross-section of the guide section inside the sows' stall being square. whereas the cross-section of the guide section outside the sow's stall is circular and the middle part of the guide between the two end positions of the feeding trough is provided with an opening for the insertion of a locking pin.

The feed trough guide is equipped with a stop with a plug-in pin.

The floor elements are provided, at least in part, with a coating, in particular rubber or plastic, to maintain the set temperature.

A supporting frame, replaceable and / or folding registration plates of technological procedures and regulations, or a record sheet of procedures, are attached to one leg and / or to one of the side walls. .

The beams formed in this way not only save material, but the beams can withstand the action of lateral forces essentially without deflection, since such action of lateral forces is converted in a special lattice into stress, the character of which is a combination of tension, compression and shear. The tensile stress of the floor elements is partly converted into a tensile stress, thus achieving its use in withstanding the multidirectional action of forces. The fact that the sow's house retains a rigid three-dimensional shape even when it is opened contributes significantly, even in this critical operating state, to ensuring the rigidity of the assembled pen structure.

The pen according to the invention has a number of further advantages resulting from the sliding arrangement of the trough, ensuring its stability during feeding and sliding during cleaning. Further advantages, in particular for ease of work and safety of the operator, will emerge from the description which follows. ...
