Description

Technical Field

[0001] The present invention relates to the technical field of pig breeding equipment, and in particular to a temperature-controlled, ventilation-controlled, energy-saving pig nursery house for young pigs. Background Art

[0002] The ventilation design of pig farms requires that the requirements of air quality, airflow, etc. must be met when building pig houses. Due to the large amount of evaporation of pig urine and the amount of water vapor exhaled, failure to discharge the urine in time will cause high humidity in the pig house. The environment inside the pig house is humid, which will cause respiratory diseases and increase the mortality rate. Therefore, the pig house needs to be ventilated regularly. Ventilation of the pig house can not only solve the humidity problem of the pig house, but also reduce the ammonia concentration in the pen and reduce the growth of bacteria in the pig house.

[0003] However, the weather is cold in winter. When ventilating the pig house, the cold air flow during ventilation will cause the pigs to catch cold and become sick. In addition, excessive intake of cold air will reduce the pigs' activity and feed intake, which is not conducive to the growth of pigs in the pig house. When it is windy or snowy, ventilation is even more difficult. Especially when there are piglets in the nursery stage in the pig house, the low temperature environment is not conducive to the growth of pigs, and even local frostbite may occur. Pigs are more likely to get sick, catch colds, and develop arthritis, piglet diarrhea, etc. Therefore, preventing piglets from getting cold is a major difficulty in ventilation.

[0004] During the piglet care period, the existing pig house generally adopts a free-range feeding method. The piglets gather together to keep warm, forming gathering areas, resulting in poor ventilation. This method cannot provide good care conditions for the piglets, which seriously affects the survival rate of the piglets. Moreover, since the piglets' body temperature regulation function is not perfect, the low temperature environment is not conducive to the growth of the piglets. A sudden drop in temperature or a continuous low temperature will cause the piglets to catch a cold. The existing pig house has poor insulation effect and cannot overcome the cold environment, which is not conducive to the care and growth of the piglets. Summary of the Invention

[0005] In response to the shortcomings of the existing piglet nursery houses during use raised in the background technology, the present invention provides a temperature-controlled, ventilation-controlled, energy-saving piglet nursery house with the advantages of good ventilation effect, energy saving and temperature control, which solves the problems of poor ventilation in piglet-dense areas and low ventilation temperature in winter raised in the above background technology.

[0007] Preferably, the length of the long ventilation slot is highly consistent with the inner diameter of the ventilation pipe. When the regulating spring is not compressed, the long ventilation slot on the side of the movable air duct is in the closed section of the air regulating duct.

[0008] Preferably, when the adjustment spring is compressed to the shortest state, the bottom plate presses the touch switch to turn on.

[0009] Preferably, the inner side and the outer layer of the movable air duct are both provided with long ventilation slots, and the two long ventilation slots are not directly opposite each other, and the heating vortex connects the ventilation duct and the interior of the movable air duct.

[0012] The present invention has the following beneficial effects:

[0013] 1.

When the adjusting spring 6 is compressed to the shortest state, the long ventilation slot 12 is completely opposite to the ventilation pipe 3, so that the ventilation area in the piglet-dense area is increased, thereby avoiding the problem of poor ventilation in the densely populated area.

[0026] See also Figure 3-4The middle of the movable air duct 11 is movably sleeved with a main shaft 13, and an auxiliary fan blade 131 is fixedly installed at the bottom end of the main shaft 13. The top end of the main shaft 13 extends to the outer end of the movable air duct 11, and a motor 132 is fixedly installed at the top of the movable air duct 11. The motor 132 is fixedly connected to the main shaft 13, and a touch switch is fixedly installed at the bottom end of the bottom plate 7. When the adjustment spring 6 is compressed to the shortest state, the bottom plate 7 presses the touch switch to turn on, and the touch switch is electrically connected to the motor 132, which controls the motor 132 to start rotating the auxiliary fan blade 131. When the piglets gathered on the bottom plate 7 are too dense, the motor 132 is pressed to turn on, and the rotation of the auxiliary fan blade 131 is used to assist ventilation of the piglets at the protective fence 8, thereby realizing the combination of natural ventilation and mechanical ventilation, so that natural ventilation is used to reduce energy consumption in sparse piglet areas, and mechanical ventilation is assisted in piglet dense areas to avoid the problem of poor ventilation in dense areas.

[0027] See also Figure 5-6The movable air duct 11 includes an inner layer and an outer layer, and an air duct sandwich 111 is formed between the inner layer and the outer layer. A ventilation slot 12 is provided on the inner side and the outer layer of the movable air duct 11, and the two ventilation slots 12 are not positioned opposite each other. A heating vortex 121 is fixedly connected between the inner ventilation slot 12 and the outer ventilation slot 12. After the airflow at the ventilation duct 3 flows into the heating vortex 121 through the ventilation slot 12 of the outer layer, it enters the movable air duct 11 through the ventilation slot 12 of the inner layer. The top of the air duct sandwich 111 is provided with a The water outlet is fixedly connected to a circulating water pipe 14 through the water outlet. The circulating water pipe 14 introduces circulating hot water into the air duct interlayer 111, thereby heating the gas passing through the heating vortex 121 to prevent the cold air flow generated by ventilation in winter from causing the piglets to get cold and become sick. The middle of the air duct interlayer 111 is movably sleeved with a water-isolating piston 141. The water-isolating piston 141 fits against the outer wall of the heating vortex 121 to prevent the circulating hot water from flowing to the bottom of the movable air duct 11. The bottom end of the water-isolating piston 141 is fixedly connected to a linkage shaft 142. The bottom of the linkage shaft 142 is fixedly connected with an air-isolating piston 143. The air-isolating piston 143 drives the water-isolating piston 141 to move up and down as a whole through the linkage shaft 142, thereby adjusting the contact length between the hot water and the water-isolating piston 141 at the air duct interlayer 111, thereby controlling the gas temperature of the air flow passing through the water-isolating piston 141. The protective fence 8 and the temperature control main pipe 9 are hollow sealed tubes, and an inert gas with a large expansion coefficient is enclosed in the hollow tube. The temperature control main pipe 9 is connected to the bottom of the air duct interlayer 111 through the temperature control disk 10. When When the temperature in the protective fence 8 of the pig house drops due to the low temperature of the ventilation air flow, the gas in the protective fence 8 and the temperature control main pipe 9 contracts, pulling the air isolation piston 143 down along the air duct interlayer 111, thereby driving the water isolation piston 141 down through the linkage shaft 142. At this time, the length of the circulating hot water above the air duct interlayer 111 increases, and the heating effect at the heating vortex 121 is improved, thereby increasing the temperature of the ventilation air flow at the movable air duct 11, preventing the piglets in the protective fence 8 from getting cold and sick due to the low temperature of the ventilation air flow.

[0028] The working principle of the method of use of the present invention is as follows:

[0029] When in use, the entire ventilation pipe 3 is set up on the top of the pig house, and its two ends are connected to the outside of the pig house, and multiple groups of temperature control and ventilation devices are set up at the bottom of the ventilation pipe 3, multiple groups of circulating water pipes 14 are interconnected and connected to the boiler, and multiple groups of protective fences 8 can be connected or separated according to the needs of childcare. When there are no piglets above a single protective fence 8, the adjusting spring 6 pushes the bottom plate 7 upward, so that the movable air duct 11 moves up to the ventilation slots 12 opened around it and retracts into the air adjustment duct 5. At this time, the movable air duct 11 above the protective fence 8 is not connected to the ventilation pipe 3, and when When the piglets enter the protective fence 8, the bottom plate 7 is pressed downward to compress the adjusting spring 6, and the movable air duct 11 is pulled down through the protective fence 8 and the temperature control main pipe 9, so that the ventilation slots 12 around the movable air duct 11 move down to be connected with the ventilation pipe 3. At this time, the air in the ventilation pipe 3 connected to the outside of the pig house flows into the pig house through the ventilation slots 12, achieving the effect of ventilation and air exchange in the area; when the piglets gather in the protective fence 8 here, the bottom plate 7 is continued to be pressed downward, so that the ventilation volume in the area increases with the increase in the number of piglets gathered there, avoiding the piglets from being exhausted due to insufficient ventilation in the densely populated area. The problem of reduced pig resistance; when the adjustment spring 6 is compressed to the shortest state, the bottom plate 7 presses the touch switch to turn on, and the touch switch is electrically connected to the motor 132, which controls the motor 132 to start rotating the auxiliary fan blades 131, so that when the piglets gathered on the bottom plate 7 are too dense, the motor 132 is pressed to turn on, and the auxiliary fan blades 131 are rotated to assist ventilation of the piglets at the protective fence 8, realizing the combination of natural ventilation and mechanical ventilation, so that natural ventilation is carried out in the sparse piglet area to reduce energy consumption, and mechanical ventilation is assisted in the dense piglet area to avoid poor ventilation in the dense area. Problem; when the temperature in the protective fence 8 of the pig house drops due to the low temperature of the ventilation air flow, the gas in the protective fence 8 and the temperature control main pipe 9 contracts, pulling the air isolation piston 143 down along the air duct interlayer 111, thereby driving the water isolation piston 141 down through the linkage shaft 142. At this time, the length of the circulating hot water above the air duct interlayer 111 is increased, and the heating effect at the heating vortex 121 is improved, thereby increasing the temperature of the ventilation air flow at the movable air duct 11, achieving the effect of automatic temperature control in the pig house, and preventing the piglets in the protective fence 8 from getting sick due to the cold due to the low temperature of the ventilation air flow.
