Abstract
Description
Technical Field
[0001] This application relates to the field of environmental control equipment for cattle farms, and in particular to a ventilation and cooling device for cattle farms. Background Technology
[0002] Creating a comfortable growing environment for cattle is crucial in the daily operation of a cattle farm. Suitable temperature and good ventilation are key factors in ensuring the healthy growth of cattle and improving breeding efficiency. When summer temperatures rise, the temperature inside the cattle shed also rises. If ventilation and cooling are not carried out in time, the cattle are prone to heat stress, which affects their growth rate, immunity, and milk production.
[0003] Currently, cattle farms commonly use ventilation equipment to regulate temperature and air quality inside the barns. However, some existing ventilation systems suffer from fixed wind direction, resulting in uneven ventilation within the barn. In some areas, air circulation is poor, and temperatures remain high, failing to provide an overall comfortable environment for the cattle. This not only affects the growth performance of the cattle but may also increase the risk of disease transmission, causing economic losses for farmers. Therefore, a ventilation and cooling device for cattle farms is proposed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a ventilation and cooling device for cattle farms to solve the problems mentioned in the background art.

[0007] The wind direction adjustment mechanism includes multiple gears and racks. The gears are fixedly connected to the top of multiple rotating shafts. The rack meshes with the gears. A sliding jaw is slidably connected to the top outer wall of the housing via two guide rails. The two ends of the sliding jaw are fixedly connected to the rack via connecting rods. A rotating disk is rotatably connected to the top outer wall of the housing. An eccentric shaft is fixedly connected to the top outer wall of the rotating disk. The eccentric shaft is movably connected to the inner wall of the middle section of the sliding jaw.
[0008] Preferably, a servo motor is fixedly installed on the top inner wall of the housing, and the end of the output shaft of the servo motor passes through the housing and is fixedly connected to the outer wall of the rotating disk's axis.

Detailed Implementation
[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0020] This application discloses a ventilation and cooling device for cattle farms. (Refer to...) Figure 1-3A ventilation and cooling device for cattle farms includes an outer shell 1, an air outlet 2 on one side of the outer shell 1, a plurality of rotating shafts 4 rotatably connected to the inner wall of the outer shell 1 at the air outlet 2, air guide plates 5 fixedly connected to the outer wall of the plurality of rotating shafts 4, and an air direction adjustment mechanism that drives the plurality of air guide plates 5 to rotate synchronously installed on the top outer wall of the outer shell 1.
[0021] The wind direction adjustment mechanism includes multiple gears 7 and racks 8. The multiple gears 7 are fixedly connected to the top of multiple rotating shafts 4. The racks 8 mesh with the multiple gears 7. The top outer wall of the housing 1 is slidably connected to a sliding jaw frame 10 via two guide rails 9. The two ends of the sliding jaw frame 10 are fixedly connected to the racks 8 via connecting rods 11. The top outer wall of the housing 1 is rotatably connected to a rotating disk 12. The top outer wall of the rotating disk 12 is fixedly connected to an eccentric shaft 13. The eccentric shaft 13 is movably connected to the inner wall of the middle section of the sliding jaw frame 10.
[0022] A servo motor 14 is fixedly installed on the top inner wall of the outer casing 1. The end of the output shaft of the servo motor 14 passes through the outer casing 1 and is fixedly connected to the outer wall of the axis of the rotating disk 12.
[0023] An air inlet 3 is provided on the side of the outer casing 1 away from the air outlet 2. A slot 17 is provided on the outer wall of the outer casing 1 near the air inlet 3. A filter screen 18 is inserted into the inner wall of the slot 17. A handle 19 is fixedly connected to the outer wall of the outer casing 1.
[0024] A mounting bracket 15 is fixedly connected to the inner wall of the outer casing 1, and a fan 16 is installed on the outer wall of the mounting bracket 15. The fan 16 is located between multiple air guide plates 5 and filter screens 18.
[0025] Limiting plates 6 are fixedly connected to the inner walls on both sides of the outer casing 1 at the air outlet 2. When the two air guide plates 5 near the inner walls on both sides of the outer casing 1 rotate and abut against the two limiting plates 6, the multiple air guide plates 5 close the air outlet 2, thus limiting the rotation angle of the multiple air guide plates 5.
[0026] Multiple fixing ears 20 are fixedly connected to the outer walls of the outer casing 1. The outer walls of the fixing ears 20 are provided with through mounting holes. The device can be fixed in a suitable position by passing screws through the mounting holes.
[0027] The implementation principle of a ventilation and cooling device for cattle farms in this application embodiment is as follows: When in use, the device can be fixed in a suitable position in the cattle shed by screws through multiple fixing ears 20 on the outside of the outer shell 1. The fan 16 is connected to an external power source and the fan 16 is started. Multiple blades on the fan 16 rotate, drawing outside air into the outer shell 1 from the air inlet 3 and blowing it into the cattle shed through the air outlet 2. When the air passes through the filter screen 18, dust and impurities can be intercepted outside the outer shell 1, thereby achieving rapid ventilation and cooling in the cattle shed.
[0028] During ventilation, the servo motor 14 is activated via the airflow adjustment mechanism. The servo motor 14 can be connected to an external power source. The output shaft of the servo motor 14 drives the rotating disk 12 to rotate. The rotating disk 12 then drives the eccentric shaft 13 to revolve around the rotating disk 12. When the eccentric shaft 13 revolves, it slides back and forth on the inner wall of the sliding jaw frame 10, thereby driving the sliding jaw frame 10 to slide left and right on the inner walls of the two guide rails 9. The two ends of the sliding jaw frame 10 drive the rack 8 to move left and right back and forth through the connecting rod 11. When the rack 8 moves left and right back and forth, it drives multiple gears 7 to rotate synchronously. The gears 7 drive the rotating shaft 4 to rotate, and the rotating shaft 4 causes multiple air guide plates 5 to swing left and right back and forth. When the multiple air guide plates 5 swing, they can change the direction and angle of the air blown out from the air outlet 2, so that the air is more evenly distributed in the cattle shed.
