How to design a cowshed
(1) There is only one row of cow beds in a single row. This kind of cowshed has small span, convenient construction and good ventilation, and is suitable for semi-open or open cowshed in Yu Jiancheng. This barn is suitable for small cattle farms.
(2) The double-row type has two rows of cow beds. Generally, a cowshed, about 100 heads, is built, which is divided into two units and spans about 12 meters, which can meet the requirements of natural ventilation. The middle of the tail-to-tail type is a dung cleaning channel, and the two sides are feed channels. There is a feeding channel in the middle of the head-to-head type and a dung cleaning channel on both sides.
2. Plastic shed cowshed is a kind of semi-open cowshed, which is a kind of thermal insulation semi-open cowshed introduced in the cold area of northern China in recent years. In winter, the semi-open (or open) beef barn is closed with plastic film, which uses solar energy and heat emitted by cattle to raise the temperature inside the barn, and the plastic film also avoids heat loss.
The following problems should be paid attention to when building a plastic film shed cowshed:
(1) is to choose the right orientation, and the plastic film shed cowshed needs to face south.
(2) Choose a suitable plastic film, such as polyethylene with high sunlight transmittance and low ground long-wave radiation transmittance, and its thickness should be 80- 100 micron; Third, it is necessary to set up vents reasonably. The air inlet of the shed is located on the downwind side of the roof, and the area of the upper protective cover and exhaust port is 20cm×20cm. The area of the air inlet is half that of the air outlet, and an air outlet is set every 3 meters.
3. Assembled cowshed This cowshed is made of steel, manufactured in the factory and equipped on site, and belongs to the open cowshed. The roof is galvanized or solar panels, and the roof beams are welded with angle steel; U-shaped groove and water tank are made of stainless steel, which can be adjusted freely with the height of cattle; Fences and fences are made of steel pipes.
The indoor setting of assembled cowshed is basically the same as that of ordinary cowshed, and its applicability and scientificity are mainly reflected in roof truss, roof and wall and adjustable feeding equipment. The roof truss beam is prefabricated by angle steel, and can be installed after the pier is built. The top of the frame beam is a purlin welded by angle steel and round steel.
The roof consists of 3 mm thick galvanized iron sheet, 4 cm thick polystyrene foam board and 5 mm thick galvanized iron sheet tile from bottom to top. The roof material is fixed on the purlin with screws, and the roof ridge is provided with an adjustable hood.
The wall about 60 cm is a brick-concrete structure (the fence cowshed does not need a wall). There is a reinforced concrete pier under each beam and column, and other parts are covered with cement mortar. Walls over 60 cm are divided into three structures: the walls on both sides of Liangwu Mountain, the breeder's living area and the forage house are "Cote Wall", and its basic skeleton is welded by angle steel, with 4 cm thick foam board filled in the middle of the angle steel, metal color plates buckled outside the skeleton, a layer of steel wire mesh fixed in the skeleton and plastered with cement mortar on the net; The partition walls of the breeder's living room, forage room and cowshed are powder cement mortar outside ordinary brick walls; Movable roller blinds are installed on the wall more than 60 cm before and after the cowshed. The roller blind is divided into two layers, the outer layer is a cotton curtain made of acrylic cotton sandwiched between double-layer curtain cloth, and the inner layer is a single-layer curtain made of single-layer curtain cloth. A steel wire mesh is installed between the two layers of roller blind, and the double-layer roller blind is fixed with windproof ropes.
The assembled cowshed has advanced design technology and adopts domestic high-quality materials. Its applicability, durability and aesthetics are first-class in China, and it is simple, time-saving and low-cost.
