Description

Technical Field

[0001] This utility model relates to the field of livestock facility technology, specifically to a movable adjustable ventilated cattle shed. Background Technology

[0002] As a crucial infrastructure in modern livestock farming, the primary function of a cattle shed is to provide a suitable living environment for cattle, ensuring their healthy growth and productivity. Modern cattle sheds typically employ enclosed or semi-enclosed structures, equipped with basic environmental control systems, including insulation materials, ventilation windows, and exhaust equipment, aiming to create a temperature-controlled and well-ventilated feeding space for the cattle. The quality of the cattle shed environment directly affects the cattle's feed intake, feed conversion rate, immunity, and reproductive performance, making it a key factor determining the profitability of livestock farming.

[0003] In practice, cattle sheds face a significant technical challenge: balancing temperature and ventilation. During cold seasons, minimizing ventilation is necessary to maintain a suitable temperature, but this leads to the accumulation of harmful gases and moisture, increasing the risk of respiratory diseases. Conversely, while increased ventilation promotes heat dissipation during hot seasons, directly introducing hot outside air exacerbates heat stress and hinders cooling. This persistent problem has multiple adverse effects on livestock production. Cattle exposed to unsuitable temperatures or poor air quality for extended periods experience decreased feed intake, slower daily weight gain, and reduced milk production, resulting in a decline in production performance. Furthermore, excessive concentrations of harmful gases can damage the respiratory mucosa, significantly increasing the incidence of diseases such as pneumonia. Utility Model Content

[0004] In order to solve the current problem that cattle sheds cannot simultaneously maintain both temperature and ventilation; This utility model provides a movable adjustable ventilated cattle shed, including a roof, gable walls, and cattle pens. The roof includes an upper roof and a lower roof, which are arranged in a staggered manner. Multiple first motors are fixedly installed at the bottom of the lower roof. The output shafts of the first motors are rigidly connected to lead screws. Multiple screw holes are opened on the upper and lower roofs to form a threaded transmission pair with the lead screws. The first motors drive the lead screws to rotate, causing the upper roof to slide under the lower roof, thereby realizing the opening and closing adjustment of the roof. Multiple electrically operated lifting curtains are installed on the outside of the cattle pen to cover the sides of the pen. The lifting of the electric curtains, in conjunction with the opening and closing of the shed roof, controls the temperature and ventilation inside the shed.

[0005] As a preferred embodiment, the electric lifting curtain includes a windproof curtain and a second motor. The upper end of the windproof curtain is fixed on the output shaft of the second motor, and a fixing clip is provided on the outside of the output shaft for fixation.

[0006] As a preferred solution, a slide rail is provided at a position of the gable corresponding to the upper shed roof, and an edge of the upper shed roof is embedded in the slide rail and slides along a direction of the slide rail.

[0007] As a preferred solution, a waterproof strip is provided at an upper end edge of the lower shed roof, and a contact surface between the waterproof strip and the upper shed roof is pressed to form a continuous sealing structure.

[0008] As a preferred solution, an upper end of the lower shed roof is provided with a slope, and an inclination angle of the slope is not less than 2 degrees.

[0009] As a preferred solution, a water outlet is provided at a position of the gable corresponding to a lower side of the lower shed roof.

[0010] The beneficial effects of the present utility model are: 1. The present utility model controls the sliding opening and closing of the upper shed roof through a shed roof structure arranged in an upper-lower staggered layer, so that managers can flexibly adjust the opening area of the shed roof according to seasons, weather and temperatures. In summer or when the weather is stuffy, opening the shed roof can effectively increase ventilation and heat dissipation to prevent heat stress of cattle; in winter or in rainy and snowy weather, closing the shed roof can effectively preserve heat, prevent cold and block rain and snow.

[0011] 2. The present utility model realizes linkage control by arranging an electric lifting curtain and an openable and closable shed roof on the outer side of a cattle pen. When enhanced ventilation is required, part of the shed roof can be opened and the side curtain can be raised at the same time to form an efficient air convection channel; when heat preservation is required, the shed roof is closed and the side curtain is lowered to form a closed warm space. The synergistic effect of the shed roof and the side curtain makes the control of temperature, humidity and ventilation in the shed more flexible, creating a comfortable and healthy living environment for cattle all the time.

Detailed Description of Embodiments

[0013] To illustrate the characteristics of the present utility model, the present utility model is further described below with reference to the accompanying drawings and embodiments.

[0014] Embodiment: Please refer to the following: Figure 1 and Figure 2 This embodiment provides a movable, adjustable, ventilated cattle shed, including a roof 1, two gable walls 2, and cattle pens 3. The roof 1 adopts a staggered structure, consisting of an upper roof 11 and a lower roof 12. The lower roof 12 is made of color steel composite panels, with a width of eight meters, and its upper end is provided with a drainage slope of three degrees. Four 1.5 kW first motors 13 are evenly installed at the bottom of the lower roof 12 on both sides, and the output shaft of each first motor 13 is rigidly connected to a lead screw 14 with a diameter of thirty millimeters. Four screw holes 15 are opened at corresponding positions on the upper roof 11 and the lower roof 12 on both sides to form a threaded transmission pair with the lead screw 14. By driving the lead screw 14 to rotate through the first motor 13, the upper roof 11 can slide within a distance of zero to two meters below the lower roof 12.

[0015] The two gable walls 2 are constructed of concrete and are 3.5 meters high. A 100-millimeter-wide sliding rail is installed on the gable wall 2 corresponding to the upper roof 11. The edge of the upper roof 11 is fitted into the sliding rail to ensure smooth sliding. The upper edge of the lower roof 12 has a 3-degree slope and is fitted with an EPDM waterproof strip. The contact surface between the waterproof strip and the upper roof 11 forms a continuous seal through pressure. Two 150-millimeter-diameter water outlets are installed on the lower side of the gable wall 2 corresponding to the lower roof 12.

[0016] Cattle pens 3 are located on both sides inside the shed and are constructed of galvanized steel pipes. Six electrically operated lifting curtains 4 are installed on the outer side of cattle pens 3. Each curtain includes a 0.8 mm thick PVC windproof curtain 41 and a second motor 42 with a power of 0.25 kW. The upper end of the windproof curtain 41 is fixed to the output shaft of the second motor 42, and a stainless steel fixing clip 43 is installed on the outside of the output shaft to ensure a secure fixation.
