Description

Technical Field

[0001] The invention relates to the field of poultry breeding, in particular to a multifunctional chicken farm ventilation device. Background Art

[0002] Chicken farm ventilation equipment is a kind of equipment that provides comfortable environmental conditions for chickens and facilitates ventilation, improves the health and production level of chickens, reduces the incidence of diseases and feeding and management costs, and achieves twice the result with half the effort for chicken farm production. Therefore, when building a chicken farm, ventilation equipment is needed.

[0003] During the use of existing chicken farm ventilation equipment on the market, it was found that most chicken farm ventilation equipment has a relatively simple and solid structure. Most of them directly achieve ventilation and filtration of the chicken farm through fans and filters. This ventilation method has the following disadvantages: (1) Due to the lack of corresponding ventilation diversion structure and insulation structure, there are problems such as the inability to quickly replace the dirty gas in the chicken farm, uneven ventilation in various areas of the chicken farm, and the sudden drop in temperature during the ventilation stage of the chicken farm that cannot meet the insulation requirements: (2) When the outdoor temperature drops or the weather is cold, conventional ventilation equipment cannot meet the heating requirements and accelerates the heat loss in the chicken farm. Special heating equipment is required; (3) The ventilation structure of the chicken farm is not equipped with a blocking structure, which allows voles to enter the chicken farm. The pathogens carried by the voles can easily infect the farmed chickens, and the voles may bite the farmed chickens, causing property losses to the chicken farm.

Multiple ventilation pipes are installed on the ventilation holes of the chicken shed, and a group of sleeves and electric valves are installed on the surface of each ventilation pipe. Each ventilation pipe is provided with an inclined portion at one end extending to the inside of the chicken shed, and air holes are provided on the surface of the inclined portion, and an elbow with an upward opening is provided at one end of the inclined portion. Heating covers are installed on the corresponding ventilation holes on the left and right sides of the chicken shed, and the heating covers are communicated with the ventilation holes.

[0007] Furthermore, a steel mesh plate is welded on the side of the heating hood facing away from the vent, and an insulation layer of polyurethane is provided on the outer surface of the heating hood shell. A mounting plate is fixed inside the heating hood, and a plurality of heating wires are mounted in parallel on the mounting plate, and the plurality of heating wires are connected in series. Two terminal heads are installed on the series circuit of the plurality of heating wires, and the two terminal heads are fixed to the outer surface of the heating hood.

[0008] Furthermore, a support ring is integrally injection-molded inside the sleeve of the ventilation pipe, and an obstruction horn is fixed to the inner ring of the support ring. An end hole is provided on the end face of the obstruction horn, and a cross is provided in the end hole. A plurality of strip holes are provided on the conical surface of the obstruction horn.

[0009] Furthermore, an installation box is fixed on the inner wall of the chicken shed, and a controller is fixedly installed in the installation box. A buzzer is fixed to the top of the installation box by screws, and an environmental detection module is fixed to the right side wall of the installation box. The environmental detection module is composed of a temperature and humidity sensor, an online odor monitor, and a carbon dioxide sensor. The temperature and humidity sensor, the online odor monitor, and the carbon dioxide sensor of the environmental detection module are all electrically connected to the controller, and the output end of the controller is electrically connected to the buzzer.

[0010] Furthermore, the inclined portion of the ventilation pipe is arranged toward the roof of the chicken shed, and the connection between the ventilation pipe and the sleeve is filled with sealant.

[0011] Furthermore, a plurality of the ventilators are distributed above the inlet and outlet and on both sides thereof, and the ventilators are specifically axial flow fans or circulating flow fans.

[0012] Furthermore, an opening is provided on the end surface of the installation box, and a box door is hingedly installed at the edge of the opening.

[0013] Furthermore, the mounting plate is composed of a base panel and an insulating layer attached to the surface thereof, and the insulating layer of the mounting plate is connected to the end of the heating wire.

[0014] Furthermore, the installation box is equipped with a built-in power supply, and the output end of the power supply is electrically connected to the controller.

[0016] Compared with the prior art, the present invention provides a multifunctional chicken farm ventilation device with the following beneficial effects: (1) The present invention forms a ventilation structure of a chicken shed by means of a ventilator, an electric hot blower, a ventilation pipe and a ventilation opening. When a plurality of ventilators installed at the inlet and outlet of the chicken shed are started, the ventilators are prompted to discharge the dirty air in the chicken shed under the rotation of their impellers, so that the chicken shed draws in outside air through the ventilation openings on both sides and a plurality of ventilation pipes under the action of the pressure difference between the inside and outside, thereby achieving the purpose of comprehensive ventilation of the chicken shed. At the same time, by starting the electric hot blower installed on the side away from the inlet and outlet of the chicken shed, the hot air blown out by the electric hot blower drives the dirty air in the chicken shed to the outside. The inlet and outlet can speed up the ventilation and air exchange of the chicken shed while facilitating heating and insulation, and are suitable for ventilation needs at night or in low temperature weather. On this basis, the inclined portion on the ventilation duct points to the roof of the chicken shed, and the inclined portion port is installed with an elbow with the opening facing upward. Combined with the air holes opened on the surface of the inclined portion, the fresh air introduced into the ventilation duct can directly reach the roof of the chicken shed, and after the air contacts the roof of the chicken shed, it is turned downward to blow. With this structure, it is easy to drive the hot air blown out by the electric blower downward, which on the one hand increases the ventilation effect and comprehensiveness, and on the other hand is beneficial to the comprehensive insulation of the chicken shed.

[0017] (2) The present invention installs an electric hot air blower on the side of the chicken shed away from the entrance and exit, and installs a heating cover on the outer side of several ventilation holes. As the electric hot air blower works, the electric hot air blower heats the outside cold air and passes it into the chicken shed, thereby achieving heat preservation of the chicken shed while ventilating. When it is necessary to heat the chicken shed, as the ventilator and the electric hot air blower work, several ventilation holes draw outside cold air into the chicken shed. At this time, the electric heating wire in the heating cover is started. Since the heating cover is connected to the ventilation hole, and the end face of the heating cover is welded with a steel mesh plate, and several electric heating wires in the heating cover are arranged in parallel, the outside cold air is heated in the process of passing through the heating cover. With this structure, the chicken shed can be quickly heated by normal heat preservation and electric heating wire auxiliary heating, which is conducive to meeting the heating needs of the chicken shed in low temperature weather.

[0018] (3) The present invention installs a sleeve with a blocking horn on the surface of the ventilation pipe. Since the cone surface of the blocking horn is provided with a plurality of strip holes and a cross is provided in the end hole of the blocking horn end face, when the electric valve of the ventilation pipe is in the open stage, the voles are intercepted by the blocking horn in the sleeve when entering the ventilation pipe, so that they cannot pass through the ventilation pipe and enter the interior. This satisfies the ventilation of the chicken shed and also has the effect of repelling rats. BRIEF DESCRIPTION OF THE DRAWINGS
