Description

Technical Field

[0001] This utility model relates to the field of livestock breeding equipment, specifically to a flow guiding device for livestock breeding. Background Technology

[0002] In livestock farming, ventilation in the sheds is crucial, typically achieved by installing openable and closable air deflectors on the walls. However, due to the generally large size and length of these deflectors, they are prone to deformation over long-term use. Furthermore, traditional drive mechanisms suffer from limited support points and low motion precision, making it difficult to maintain a stable closed state. These factors combined lead to poor sealing at the interface between the deflector and the wall, resulting in poor airtightness and uncontrollable insulation performance in the shed. Utility Model Content

[0003] The purpose of this utility model is to provide a flow guiding device for livestock farming, so as to solve the existing technical problems in the background art.

[0004] The technical solution provided by this utility model is as follows: A flow guiding device for livestock breeding is provided, including a fixed plate, a flow guiding plate, a sealing strip, a rack, and a rack adjusting mechanism. A vent is provided on the fixed plate, and the flow guiding plate is positioned corresponding to the vent, with its bottom hinged to the fixed plate. The sealing strip wraps around the vent and is positioned between the flow guiding plate and the fixed plate. When the top of the flow guiding plate is away from the fixed plate, it is in an open state, forming a flow guiding channel between the flow guiding plate and the fixed plate, which communicates with the vent. When the top of the flow guiding plate is pressed against the fixed plate, it is in a closed state, with the sealing strip abutting against the flow guiding plate and the fixed plate on opposite sides. The rack adjusting mechanism includes a first gear and a driving mechanism. The driving mechanism is mounted on the fixed plate, and the first gear is driven and rotated by the driving mechanism. The rack meshes with the first gear, and one end of the rack is hinged to the flow guiding plate.

[0005] Based on the above technical solution, the sealing strip is fixedly installed on the fixing plate.

[0006] Preferably, the sealing strip is fixedly installed on the side of the guide plate facing the fixed plate.

[0007] Preferably, an adjustable locking device is provided between the guide plate and the rack. The adjustable locking device includes a connecting bolt and a U-shaped connector. The connecting bolt passes through the guide plate and is threadedly connected to the U-shaped connector. The U-shaped connector is hinged to the rack.

[0008] Based on the above technical solution, multiple adjustable locking devices are installed on the guide plate in the horizontal direction, and each is hinged to a corresponding rack.

[0009] Preferably, the rack is an arc-shaped structure adapted to the trajectory of the deflector in its open state, the opening of the arc-shaped structure faces downward, and the teeth of the rack are located below the rack.

[0010] Preferably, the rack and pinion adjustment mechanism further includes a guide rod, which is driven and rotated by a drive mechanism. A support rod is fixedly provided on the end face of the fixed plate on the side opposite to the guide plate. A through hole adapted to the outer diameter of the guide rod is provided on the support rod. The guide rod passes through the through hole and is rotatably connected to the support rod. The first gear is sleeved on the guide rod and is coaxially fixedly connected to the guide rod.

[0011] Based on the above technical solution, multiple first gears are simultaneously fixedly sleeved on the guide rod, and the number of the first gears corresponds to the number of racks.

[0012] Preferably, the guide rod is further provided with a limiting plate and a guide wheel. There are two limiting plates, which are respectively located on both sides of the first gear and hinged to the guide rod. The guide wheel is rotatably connected to the top of the two limiting plates through a rotating shaft, and the guide wheel is rotatably connected to the back of the rack.

[0013] Preferably, the driving mechanism includes a motor, a second gear, a third gear, and a transmission chain. The second gear is driven and rotated by the motor. The transmission chain is wound around both the second gear and the third gear. One end of the guide rod is coaxial with and fixedly connected to the third gear.

[0014] The beneficial effects of the technical solution provided by this utility model are as follows: (1) By setting a sealing strip outside the ventilation opening, and using an adjustable locking device at different positions of the guide plate and an arc-shaped rack that matches the opening trajectory of the guide plate, the closed state of the large-volume guide plate is precisely controlled, ensuring that each point of the guide plate can be tightly sealed with the fixed plate, thereby improving the sealing and temperature controllability of the internal space of the breeding house.

[0015] (2) By installing the sealing strip onto the fixed plate, the sealing strip is prevented from obstructing airflow in the airflow channel when the guide plate is opened, thus ensuring the air intake effect. Attached Figure Description

[0018] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Example 1 like Figures 1 to 4 As shown, a flow guiding device for livestock farming includes a fixed plate 11, a flow guiding plate 21, a sealing strip 3, a rack 41, and a rack adjusting mechanism. The fixed plate 11 can also be a wall of the livestock shed, and the flow guiding plate 21 is installed on the indoor side of the wall. A ventilation opening 12 is provided on the fixed plate 11, and the flow guiding plate 21 is positioned corresponding to the ventilation opening 12. The bottom of the flow guiding plate 21 is hinged to the fixed plate 11, and the top of the flow guiding plate 21 can be opened and closed relative to the fixed plate 11. When the top of the flow guiding plate 21 is away from the fixed plate 11, it is in the open state. At this time, a flow guiding channel 22 is formed between the flow guiding plate 21 and the fixed plate 11. Figure 4 The flow channel 22 is connected to the vent 12 to achieve ventilation. The sealing strip 3 is wrapped around the vent 12 and is disposed between the flow guide plate 21 and the fixing plate 11. When the top of the flow guide plate 21 is pressed against the fixing plate 11, it is in a closed state. At this time, the sealing strip 3 abuts against the flow guide plate 21 and the fixing plate 11 on opposite sides, thereby completing the tight fit between the flow guide plate 21 and the fixing plate 11 and achieving a tight seal. Preferably, the sealing strip 3 is fixedly installed on the side of the flow guide plate 21 facing the fixing plate 11, so that the sealing strip 3 can be replaced and installed synchronously with the flow guide plate 21.

[0020] The rack and pinion adjustment mechanism is used to control the opening and closing angle of the guide plate 21. Specifically, the rack and pinion adjustment mechanism includes a first gear 47, a guide rod 46, and a drive mechanism. A support rod 13 is fixedly installed on the end face of the fixed plate 11 opposite to the guide plate 21. The support rod 13 has a through hole that matches the outer diameter of the guide rod 46. The guide rod 46 passes through the through hole and is rotatably connected to the support rod 13. The first gear 47 is sleeved on the guide rod 46 and is coaxially fixedly connected to the guide rod 46. To ensure transmission stability, the guide rod 46 is also provided with a limiting plate 48 and a guide wheel 49. Two limiting plates 48 are provided, located on both sides of the first gear 47 and hinged to the guide rod 46 to axially limit the first gear 47. The guide wheel 49 is rotatably connected to the top of the two limiting plates 48 through a rotating shaft, and the guide wheel 49 is rotatably connected to the back of the rack 41, effectively reducing friction. The guide rod 46 is driven and rotated by a drive mechanism, thereby causing the first gear 47 to rotate synchronously. The drive mechanism is mounted on a fixed plate and includes a motor 42, a second gear 43, a third gear 44, and a transmission chain 45. The second gear 43 is driven and rotated by the motor 42. The transmission chain 45 is wound around both the second gear 43 and the third gear 44. One end of the guide rod 46 is coaxial with and fixedly connected to the third gear 44. When the motor 42 is working, it drives the second gear 43 to rotate through the transmission chain 45, thereby causing the guide rod 46 and the first gear 47 to rotate synchronously. The rack 41 meshes with the first gear 47, and one end of the rack 41 is hinged to the guide plate 21. The rack 41 is an arc-shaped structure adapted to the opening trajectory of the guide plate 21. The center of curvature of this arc is located on the hinge axis between the guide plate 21 and the fixed plate 11, and its radius is equal to the distance from the hinge point between the guide plate 21 and the fixed plate 11 to the hinge point between the rack 41 and the guide plate 21. The opening of the arc-shaped structure faces downward, and the teeth of the rack 41 are located below the rack 41 to ensure smooth transmission. Multiple first gears 47 are fixedly sleeved on the guide rod 46. The number of first gears 47 corresponds to the number of racks 41, thereby simultaneously adjusting the movement amplitude of each rack 41, and thus simultaneously controlling the opening and closing actions of multiple positions of the guide plate 21.

[0021] To further optimize the sealing effect, an adjustable locking device is provided between the guide plate 21 and the rack 41. This adjustable locking device includes a connecting bolt 53 and a U-shaped connector 52. The connecting bolt 53 passes through the guide plate 21 and is threadedly connected to the U-shaped connector 52. The U-shaped connector 52 is hinged to the rack 41. By rotating the connecting bolt 53, the relative distance between the guide plate 21 and the U-shaped connector 52 is adjusted, thereby adjusting the relative distance between the fixing plate 11 and the guide plate 21. This allows for adjustment of the tightness of the guide plate 21 when closed, based on the deformation of the sealing strip 3 and the guide plate 21 at that location. Preferably, multiple adjustable locking devices and corresponding racks 41 and first gears 47 are installed horizontally on the guide plate 21. These multiple adjustable locking devices are distributed at different positions on the guide plate 21, thereby allowing for individual control of different positions of the guide plate 21.

[0022] The connecting bolt 53 passes through the first nut 51, the first washer 50, the guide plate 21, the second washer 54, and the second nut 55 in sequence. The guide plate 21 is fixed on the connecting bolt 53 by tightening the first nut 51 and the second nut 55.

[0023] To improve structural strength and service life, the fixing plate 11 is made of aluminum alloy and the guide plate 21 is made of fiberglass.

[0024] Example 2 The difference between this embodiment and the above embodiments is that, Figure 5 and Figure 6 As shown, the sealing strip 3 is fixedly installed on the fixed plate 11, thereby keeping the sealing strip 3 away from the air inlet side of the outlet of the guide channel 22, avoiding air backflow at the outlet of the guide channel 22 due to the obstruction of the sealing strip 3, and ensuring that air can smoothly pass through the guide channel 22 and enter the breeding house when the guide plate 21 is opened to any angle, without affecting the ventilation effect.

[0025] The foregoing has shown and described the basic principles and main features of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments. Therefore, the embodiments should be regarded as exemplary and non-limiting. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims within this utility model.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
