Description

Technical Field

[0001] This utility model relates to the field of ventilation and air exchange equipment technology, specifically an automatic ventilation and air exchange equipment for cattle sheds. Background Technology

[0002] Ventilation equipment refers to devices that achieve indoor and outdoor air exchange through mechanical or natural means. They are mainly used to exhaust polluted air and introduce fresh air to maintain air quality and environmental comfort. Through forced circulation or heat exchange technology, they can expel indoor moisture, odors or harmful gases, while filtering, heating or purifying the introduced outdoor air to form a continuous airflow circulation, in order to assist livestock pens where high temperatures cannot circulate effectively.

[0003] The utility model with announcement number CN220211398U discloses a ventilation and air exchange device for cattle sheds in cattle farming. By setting a disassembly component, the expansion mechanism can be disassembled more easily during use, which is convenient for reuse and maintenance. By setting an installation component, the expansion mechanism can be installed more easily during use. By setting an extension component, the extension pipe can be extended during use, which is convenient for installation and replacement.

[0004] However, the ventilation and air exchange device disclosed above for cattle sheds still has the following problems in actual use: ventilation and exhaust are assisted by an upward-opening extension component, but the other end of the ventilation and air exchange device is connected to the interior of the cattle shed. During the air exchange process, its direction remains unchanged, which cannot help to exhaust the air inside the cattle shed from multiple angles. At the same time, there are right-angle pipes, which can easily cause the attracted weeds and dirt to clog the ventilation and air exchange device, making it difficult to improve the efficiency of the ventilation and air exchange device.

[0005] Therefore, we propose an automatic ventilation and air exchange device for cattle sheds to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an automatic ventilation and air exchange device for cattle sheds. This device addresses the problem that existing ventilation and air exchange devices use upward-opening extension components to assist ventilation and exhaust, but the other end of the ventilation and air exchange device is connected to the interior of the cattle shed. During the ventilation process, the direction of the device remains fixed, making it impossible to assist in exhausting air from multiple angles. In addition, the presence of right-angle pipes can easily lead to the attraction of weeds and dirt that clogs the ventilation and air exchange device, making it difficult to improve the efficiency of the ventilation and air exchange device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic ventilation and air exchange device for cattle sheds, comprising an outer frame and a drive motor fixedly installed inside the rear of the outer frame, wherein ventilation fan blades are fixedly installed on the front output shaft of the drive motor; further comprising: The front end of the equipment frame is provided with a ventilation mechanism, which includes a ventilation arc pipe, and a guide toothed ring is fixedly installed at the rear end of the ventilation arc pipe. The ventilation arc pipe is provided with a dust removal mechanism at its front end, and the dust removal mechanism includes a dust removal brush plate, which slides against the front end of the ventilation arc pipe.

[0010] Preferably, the ventilation mechanism includes a guide gear ring that is rotatably mounted on the front end of the equipment frame via a bearing, and the guide gear ring meshes with the drive gear at the front end of the equipment frame. The guide gear ring drives the ventilation arc pipe fixedly connected to the front end to rotate, and the ventilation arc pipe is an arc-shaped tubular structure that rotates circumferentially to improve the ventilation range.

[0011] Preferably, the dust removal mechanism includes a guide slide rod, and the rear end of the guide slide rod slides through the left and right sides of the front of the equipment frame, and the rear end of the guide slide rod is connected to the inner wall of the equipment frame by a return spring.

[0012] Preferably, the dust removal mechanism includes a hinged seat, which is rotatably mounted on the left and right sides of the rear end of the dust removal brush plate. The rear end of the hinged seat is rotatably connected to the front end of the guide slide rod. In the initial state, the guide slide rod drives the dust removal brush plate to always be in contact with the front end of the ventilation arc pipe through a reset spring.

[0013] Preferably, the dust removal mechanism includes a filter screen, which is fixedly installed at the front end of the ventilation arc pipe to filter weeds and dirt mixed during the air exchange process, so as to avoid affecting the normal operation of the ventilation fan blades inside the equipment frame. The filter screen rotates with the ventilation arc pipe and is scraped and cleaned by the attached dust removal brush plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The automatic ventilation and air exchange equipment for the cattle shed has a ventilation arc pipe at the front end of the equipment frame installed inside the cattle shed. During operation, the rotating ventilation arc pipe agitates the hot air inside the cattle shed, increasing the ventilation range. At the same time, the tensioned dust removal brush plate is always in close contact with the end of the ventilation arc pipe, assisting in scraping and cleaning weeds and dirt. The specific details are as follows: 1. The outer frame of the equipment is installed inside the cowshed at one end near the ventilation arc pipe. The internal drive motor drives the ventilation fan blades to rotate, so that the hot air inside the cowshed is drawn out through the rotation of the ventilation fan blades and then discharged out through the other end of the outer frame of the equipment.

[0015] Furthermore, the drive motor drives the drive shaft to rotate via a pulley assembly. The drive shaft rotates through a drive gear meshing with a guide ring, so that the guide ring drives the fixedly connected ventilation arc pipe to rotate in a circular motion, thereby agitating the hot air inside the cattle shed and increasing the ventilation range.

[0016] 2. The equipment frame is installed at one end of the cattle shed. Air is drawn in through a rotating ventilation arc pipe, and the filter screen inside the ventilation arc pipe filters out weeds and dirt from inside the cattle shed, preventing weeds and dirt from entering the equipment frame and affecting the ventilation efficiency.

[0017] 3. The inner wall of the equipment frame is connected to the guide slide rod by a reset spring, so that the dust removal brush plate connected to the guide slide rod through the hinged seat is always in a tensioned state, so that the dust removal brush plate is always in close contact with the end of the ventilation arc pipe, which helps to scrape and clean weeds and dirt.
