Description

Technical Field

[0001] This utility model relates to the field of egg-laying hen breeding technology, and in particular to a ventilation and air exchange device for egg-laying hen breeding houses. Background Technology

[0002] Chinese patent document CN222692520U discloses a ventilation and air exchange device for broiler chicken farming, including a wall with a through hole. A mounting bracket is fixedly connected to the through hole, and a drive motor is fixedly mounted on the mounting bracket. A fan blade is fixedly connected to the output shaft of the drive motor. A filter screen is provided on the outside of the wall, and a cleaning component is provided on the wall. The cleaning component includes a positioning frame. A reducer motor drives a lead screw to rotate, thereby moving a slider along a slide groove. The movement of the slider drives a brush to clean the surface of the filter screen, scraping off the dust adsorbed on the filter screen. Water is sprayed through a fan-shaped nozzle to wet the dust and impurities, thereby increasing the weight of the dust. The impurities and dust fall into a collection hood and are discharged from the drain pipe with the water flow, preventing them from being adsorbed onto the filter screen again. The rinsing with water further improves the cleaning effect.

[0003] However, the filters of the aforementioned devices, including some existing devices, are generally installed using bolt fastening. The disassembly process is cumbersome and requires special tools. In the environment of multiple ventilation points in the breeding house, the high-frequency cleaning and maintenance of the filters not only significantly increases the intensity of manual labor, but also causes the continuous ventilation in the house to be interrupted due to the long downtime for disassembly and assembly, affecting the stability of the environment. Therefore, we propose a ventilation and air exchange device for egg-laying hen breeding houses. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation and air exchange device for egg-laying hen farms, which can solve the problem of time-consuming and labor-intensive filter replacement in some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and air exchange device for an egg-laying hen breeding house, comprising: The mounting plate has a movable frame attached to its front side. Two sets of sliding grooves are opened on the front side of the mounting plate. Two sets of sliders are fixedly installed on the rear outer surface of the movable frame. Both sets of sliders are slidably installed in the corresponding sliding grooves. Two sets of slots are opened on the front side of the movable frame. A set of filter plates is locked in each of the two sets of slots. A positioning mechanism is installed on the active frame and is used to position the active frame. A limiting mechanism is provided on the movable frame. The limiting mechanism includes two sets of limiting frames rotatably mounted on the front outer surface of the movable frame, and two sets of spring pins provided on the front outer surface of the movable frame. Both sets of spring pins are located at the inner corners of the corresponding limiting frames.

[0006] Preferably, the spring pin consists of a retaining pin and a spring. The front side of the movable frame has two sets of grooves, each set of grooves is provided with a set of retaining pins, and each set of retaining pins is fixedly installed with a set of springs between the corresponding inner wall of the groove and the inner wall of the groove.

[0007] Preferably, the positioning mechanism includes a positioning rod, a pull handle, a return spring, and positioning holes. The positioning rod is movably passed through the movable frame. Two sets of positioning holes are opened on the front side of the mounting plate. One end of the positioning rod is inserted into the corresponding positioning hole, and the other end of the positioning rod is fixedly installed with a pull handle. A return spring is sleeved on the positioning rod. One end of the return spring is fixedly connected to the outer surface of the front side of the movable frame, and the other end of the return spring is fixedly connected to the pull handle.

[0008] Preferably, a cylinder is integrally formed on the rear outer surface of the mounting plate, a connecting plate is fixedly installed between the inner walls of the cylinder, a servo motor is fixedly installed on the front outer surface of the connecting plate, and a fan is rotatably installed on the rear outer surface of the connecting plate, with the shaft of the servo motor being connected to the fan drive.

[0009] Preferably, an activated carbon filter screen is fixedly installed on the rear outer surface of the cylinder.

[0010] Preferably, a sealing gasket is fixedly installed on the rear outer surface of the mounting plate.

[0011] Preferably, the mounting plate has four sets of mounting holes that are evenly distributed at the four corners of the mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The ventilation system in this egg-laying hen house, through the cooperation of limiting and positioning mechanisms, allows for quick disassembly and assembly of filter plates. Furthermore, while one set of filter plates is being disassembled and cleaned, another clean set can be moved to the filtration position to achieve seamless filtration, avoiding equipment downtime. This solves the problem that existing devices typically use bolt-fastened filter installations, resulting in cumbersome disassembly processes requiring specialized tools. In environments with multiple ventilation points in the hen house, frequent filter cleaning and maintenance not only significantly increases labor intensity but also leads to interruptions in ventilation continuity due to prolonged downtime for disassembly and assembly, affecting environmental stability. This system improves the practicality of the equipment.

[0013] The ventilation system in this egg-laying hen farm uses activated carbon filters to remove odors from the air, preventing environmental pollution. Simultaneously, the sealing gaskets ensure the airtightness of the equipment installation, guaranteeing its effectiveness and facilitating its promotion and use. Attached Figure Description
