[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: an air supply device for animal husbandry, including a fan 1, which is the main body of the air supply device used for animal husbandry. The fan 1 can be placed near the entrance of the animal husbandry farm to inhale external air for air supply. The outer wall of the bottom end of the fan 1 is fixedly connected with a mounting plate 4, and the outer wall of the mounting plate 4 is slidably connected with a base 5. The base 5 can be fixed to the ground by bolts to fix the fan 1 as a whole. The inner wall of the base 5 is provided with a buffer mechanism. When the fan 1 is running, the mounting plate 4 moves up and down on the inner wall of the base 5 due to the vibration of the device. The buffer mechanism can play a buffering effect and reduce noise. The inner wall of the fan 1 is provided with a fixing mechanism, through which the filter 6 in the fan 1 can be conveniently and quickly disassembled and installed to clean the filter 6.

[0033] Reference Figure 2-Figure 3The fixing mechanism includes a trapezoidal block 201, the outer wall of the trapezoidal block 201 is slidably connected to the inner wall of the slide groove 206, and the trapezoidal block 201 can be pressed to move laterally in the top inner wall of the fan 1. The outer wall of the trapezoidal block 201 is fixedly connected with a protrusion 202, and the protrusion 202 penetrates the outer wall of the top rear side of the fan 1. By pressing the protrusion 202, the trapezoidal block 201 can be driven to move inward along the inner wall of the fan 1. The inner wall of the fan 1 is provided with a slide groove 206, and the inner wall of the slide groove 206 The wall is slidably connected with a connecting rod 203, and two groups of connecting rods 203 are arranged and symmetrically distributed in the inner walls of the two groups of slide grooves 206. One end of the connecting rod 203 is fixedly connected to the outer wall of the stopper 205, and the other end of the connecting rod 203 is slidably connected to the outer wall of the trapezoidal block 201. When not affected by external forces, the connecting rod 203 maintains contact with the short side of the trapezoidal block 201. When the trapezoidal block 201 is pressed, the connecting rod 203 is squeezed and can move to both sides.

[0034] Reference Figure 2-Figure 3 The inner wall of the fan 1 is elastically connected to a block 205 through a spring 204, and the block 205 keeps the arc surface facing the rear side of the fan 1. The filter 6 can be installed by moving it inward along the inner wall of the fan 1. One end of the spring 204 is fixedly connected to the outer wall of the block 205, and the other end of the spring 204 is fixedly connected to the inner wall of the fan 1. During installation, the outer wall of the filter 6 exerts an extruding force on the arc surface of the block 205, so that the block 205 moves inward along the inner wall of the fan 1, and the spring 204 contracts under the force, and the outer wall of the block 205 is slidably connected to the inner wall of the fan 1. When the filter 6 moves to the position corresponding to the slot 7 and the block 205, the block 205 pops out due to the elastic force of the spring 204 itself and engages with the slot 7, so that the filter 6 can be fixed.

[0035] Reference Figure 2-Figure 3 The inner wall of the fan 1 is detachably mounted with a filter 6, which can filter impurities such as dust and hair in the air to maintain the cleanliness of the supplied air, thereby improving the air quality in the livestock house. The outer wall of the filter 6 is provided with a slot 7, and the block 205 is engaged with the slot 7. The spring 204 can drive the block 205 to pop outward due to its own elastic force, and the straight surface of the block 205 contacts the inner wall of the slot 7, which can prevent the filter 6 from moving outward and falling off, thereby fixing the filter 6.

[0036] Reference Figure 4 The buffer mechanism includes a fixed rod 302, which is fixedly connected to the inner wall of the base 5. The fixed rod 302 does not contact the inner wall of the bottom end of the base 5, so that the damping ring 305 can slide on the outer wall of the fixed rod 302. The two ends of the fixed rod 302 are fixedly connected to the inner walls on both sides of the base 5. The outer wall of the fixed rod 302 is fixedly connected with a rubber ring 303. The outer wall of the fixed rod 302 is slidably connected with the damping ring 305. The rubber ring 303 is provided in multiple groups. The damping ring 305 is a prior art. The damping ring 305 moves on the outer wall of the rubber ring 303 to increase friction.

[0037] Reference Figure 4 The outer wall of the damping ring 305 is hinged with a rotating rod 304, and the top of the rotating rod 304 is hinged to the outer wall of the bottom end of the mounting plate 4. When the mounting plate 4 moves up and down due to vibration, the rotating rod 304 is driven to flip, and the damping ring 305 is driven to move on the outer wall of the rubber ring 303. Due to the large friction between the two, the vibration amplitude of the mounting plate 4 can be reduced, thereby having a buffering effect on the mounting plate 4. The inner wall of the base 5 is fixedly connected with an elastic telescopic rod 301, and the elastic telescopic rod 301 is provided with four groups, which can support the fan 1. One end of the elastic telescopic rod 301 is fixedly connected to the inner wall of the base 5, and the other end of the elastic telescopic rod 301 is fixedly connected to the outer wall of the bottom end of the mounting plate 4. When the mounting plate 4 vibrates, the elastic telescopic rod 301 is vibrated and retracted and rebounded, which can also have a certain buffering effect. Combined with the movement of the damping ring 305 on the outer wall of the rubber ring 303, the buffering effect is better, and a certain noise reduction effect can be achieved, thereby reducing interference and pollution to the surrounding environment.

[0038] Working principle: The operator can fix the base 5 on the ground near the entrance of the livestock farm by bolts, and operate the fan 1 to suck external air into the farm for ventilation. Since the fan 1 will vibrate and generate loud noise during operation, the vibration will drive the mounting plate 4 to move up and down in the base 5, causing the elastic telescopic rod 301 to shrink and rebound under force, and drive the rotating rod 304 to flip up and down, so that the damping ring 305 can move back and forth laterally on the outer wall of the rubber ring 303. Since the friction between the damping ring 305 and the rubber ring 303 is large, the vibration amplitude of the mounting plate 4 can be reduced, thereby achieving a better buffering effect, reducing vibration and reducing noise generation, so as to avoid excessive noise affecting surrounding personnel.

[0039] When the fan 1 is running, the external air can filter dust, hair and other impurities in the air through the filter 6, and relatively clean air can be sucked into the farm. However, when the filter 6 has been used for a long time, a large amount of impurities will adhere to the surface, affecting the air circulation effect. At this time, the operator can press the protrusion 202 inward to drive the trapezoidal block 201 to move inward, so that the connecting rod 203 contacts the long side wall of the trapezoidal block 201. The squeezing force of the connecting rod 203 can drive the stopper 205 to move to both sides and break away from the slot 7, so that the limit of the filter 6 can be released. The filter 6 can be removed quickly and easily. When the filter 6 needs to be installed after being replaced, the filter 6 can be moved inward along the inner wall of the rear end of the fan 1. The outer wall of the filter 6 squeezes the arc surface of the block 205, so that the block 205 moves inward along the inner wall of the fan 1. When the filter 6 moves to the position corresponding to the slot 7 and the block 205, the spring 204 drives the block 205 to pop outward due to its own elastic force and engages with the slot 7, so that the filter 6 can be fixed. Therefore, the filter 6 can be disassembled and installed without turning the bolts multiple times, which is more convenient and quick.
