Description

Technical Field

[0001] This utility model relates to the field of ventilation regulation technology, specifically a ventilation regulation device for cattle sheds in cattle farms. Background Technology

[0002] The problem stems from environmental issues such as high temperature, high humidity, and harmful gases in large-scale cattle farms. In order to improve these issues and ensure the production performance of cattle herds, the technology has gradually developed from relying on natural ventilation in the early days of cattle shed design to actively controlling the environment.

[0003] A search revealed existing technology (application number: CN202221567890.3), which describes "a ventilation device for livestock farming, including a mounting frame, a fan assembly and a dust filter. The mounting frame is used to fix the device, the fan assembly controls the ventilation intensity by adjusting the speed, and the dust filter is fixed to the air inlet of the fan assembly by bolts to filter dust in the air."

[0004] This utility model focuses on the basic ventilation needs of livestock farming scenarios. It controls the ventilation volume by adjusting the fan speed and uses a single-layer dust filter to ensure air cleanliness. However, it does not have a mechanically linked wind-adjusting blade structure, so it cannot accurately control the ventilation direction and opening. Furthermore, the filter disassembly and assembly rely on bolt operation, resulting in low maintenance efficiency. In addition, it does not have a dedicated filter component designed to address the common problem of insect intrusion in cattle farms, which limits its functional adaptability. Therefore, it needs to be improved. Utility Model Content

[0030] Example 1:

[0031] like Figures 1 to 3 As shown, this embodiment provides a ventilation and adjustment device for cattle sheds in cattle farms, including: a fixed structure 1, including a fixed plate 101, and the fixed plate 101 is provided with connecting holes 102 around its perimeter for fixing devices; an adjustment structure 2, arranged in the middle of the fixed structure 1, including a protective shell 201, and the protective shell 201 is provided with an arc-shaped sliding groove; and a filter structure 3, provided in two sets, arranged on both sides of the adjustment structure 2.

[0032] In this embodiment, the regulating structure and the filtering structure constitute a ventilation regulating device for cattle sheds in a cattle farm according to this application.

[0033] It should also be noted that the ventilation control in this application can refer to ventilation control equipment for cattle sheds in cattle farms, ventilation control equipment for pig sheds in pig farms, etc. Figure 1 In this embodiment, ventilation regulation is described as an example of ventilation regulation equipment for cattle sheds in cattle farms. Of course, other types of ventilation regulation can also adopt similar structures, which will not be described in detail below.

[0034] Understandable, Figure 1 This illustration only shows some components of the ventilation and control equipment in a cattle farm barn. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the ventilation and control equipment in cattle sheds of cattle farms can also include, compared to... Figure 1 More or fewer parts.

[0035] It should also be understood that the motors were all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control methods and circuit connections will not be described in detail.

[0036] In addition, in this embodiment, the fixing structure 1 fixes the device through the connecting hole 102, the adjusting structure 2 realizes ventilation adjustment through the arc-shaped sliding groove and the internal linkage structure, and the filtering structure 3 filters the air.

[0037] Specifically, the outer ring 202 is arranged inside the protective shell 201 and has multiple sets of through holes; the spindle 203 is arranged at the center of the outer ring 202 and has multiple sets of rotating blocks.

[0038] In this embodiment, the outer ring 202 provides the mounting base, and the spindle 203 is connected to the air regulating blade 204 through the rotating block, providing support and rotation fulcrum for the air regulating blade 204.

[0039] Example 2:

[0040] Based on Example 1, in order to further improve the adjustment efficiency, an adjustment structure 2 is arranged inside the fixed structure 1;

[0041] Specifically, the adjustment structure 2 includes: a sliding groove 208, which is provided in multiple sets, passing through the through hole opened in the outer ring 202, and rotatably connected to the protective shell 201, and also having a sliding groove; an air regulating blade 204, which is arranged inside the outer ring 202, with one end connected to the sliding groove 208 and the other end connected to the rotating block provided in the spindle 203, and rotatably connected to the spindle 203; a slide rail 206, which is arranged inside the protective shell 201 and outside the outer ring 202; multiple rollers 205, which are provided in multiple sets, arranged on the outer ring 202, and slidably connected to the slide rail 206; and multiple transmission rods 207, which are provided in multiple sets, arranged on the slide rail 206, and slidably connected to the sliding groove opened in the sliding groove 208.

[0042] In a preferred embodiment, the two ends of the air regulating blade 204 are respectively connected to the slide groove 208 and the rotating block of the spindle 203. The roller 205 is made of rubber and is used to limit the sliding direction of the slide rail 206 so that the slide rail 206 rotates. The transmission rod 207 moves in the sliding groove of the slide groove 208 to drive the air regulating blade 204 to rotate, thereby realizing the adjustment of the opening and closing angle of the air regulating blade 204 and controlling the ventilation volume.

[0043] Specifically, the adjusting rod 209 is arranged on the slide rail 206 and is slidably connected to the arc-shaped sliding groove opened in the protective shell 201. It also has a through hole for adjusting the opening and closing of the air regulating blade 204. The fixing block 210 is arranged on the protective shell 201 and has multiple sets of threaded holes. The bolt 211 is threaded through the through hole opened in the adjusting rod 209 and the threaded hole opened in the fixing block 210 for fixing the adjusted position.

[0044] In this embodiment, the adjusting rod 209 slides along the arc-shaped sliding groove to drive the transmission rod 207. After adjustment, the bolt 211 connects the adjusting rod 209 to the fixed block 210 to fix the position, thereby fixing the opening and closing angle of the air regulating blade 204 and maintaining a stable ventilation volume.

[0045] Specifically, the fan 212 is arranged inside the protective housing 214, and one end is connected to the output end of the motor 213.

[0046] With this configuration, the output of motor 213 drives fan 212 to rotate, accelerating airflow. By adjusting the rotation direction of motor 213, the device can achieve suction or exhaust.

[0047] Example 3:

[0048] Based on Example 2, in order to further improve the filtration efficiency, a filter structure 3 is arranged on both sides of the adjustment structure 2;

[0049] Specifically, filter 301 is arranged on one side of protective shell 201 and is magnetically connected to protective shell 201 by a magnetic block for insect prevention.

[0050] Among them, filter screen 301 is fixed by magnetic blocks to block insects from entering the cowshed through the ventilation openings, thus ensuring the environment of the cowshed.

[0051] Specifically, filter screen 302 is arranged on one side of protective shell 214 and is magnetically connected to protective shell 214 by a magnetic block for dust prevention.

[0052] In this embodiment, filter screen 302 is fixed by a magnetic block to filter dust in the air and prevent it from entering the device, thus maintaining the durability of the device.

[0053] In actual use, first, fix the fixing plate 101 to the wall using cross bolts 211. Then, attach the filter screen 301 to the protective shell 201 and the filter screen 302 to the protective shell 214. Start the device, and the internal motor 213 will drive the fan 212 to rotate. When the air volume needs to be adjusted: by moving the adjusting rod 209 to the right, the adjusting rod 209 drives the slide rail 206 to rotate. The transmission rod 207 fixed on the slide rail 206 slides inside the slide groove 208. The rotation of the slide groove 208 drives the air regulating blades 204 to rotate. By adjusting the angle of the adjusting rod 209, the opening and closing size of the air regulating blades 204 is linked to control the air volume.

[0054] Precisely adapted to the actual needs of cattle farms. Its mechanically linked air regulating blades 204, compared to the traditional method of adjusting only the fan speed, can more accurately control the ventilation volume and direction to meet the ventilation needs of different areas of the cattle shed; paired with motor 213 driving fan 212, it can flexibly switch between active air supply and passive ventilation modes to cope with different scenarios such as stuffy and windless conditions.

[0055] Meanwhile, the dual filter screen for insect prevention and dust prevention uses magnetic connection, which is easier to disassemble and maintain than bolt fixing. It can also specifically solve the problems of insect intrusion and dust in cattle sheds. In addition, the stable fixing structure ensures reliable operation of the equipment. The overall function is practical and highly adaptable.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
