A fan used in animal husbandry and its production method

Abstract

The invention relates to the technical field of heat dissipation of colony houses for livestock, in particular to a fan used for animal husbandry and a production method of the fan. The fan comprises a fan body and a support, a power source is connected with an electric control box and a motor, the support consists of a rotating system, a power system and an electric control system, a reducer with an oblique gear and a turbine is arranged on a motor shaft of the rotating system, a transmission shaft and the electric control box are disposed on the reducer, a plurality of rotating shafts are disposed on the transmission shaft, couplers are equidistantly disposed on the transmission shaft on the left sides and the right sides of the rotating shafts, a bearing is arranged in an inner cavity of each rotating shaft, the bearings are connected with plane bearings, a gear is disposed outside each rotating shaft, the gears drive the turbine, a fan angle adjusting support is disposed on the lower portions of the plane bearings of the rotating shafts and provided with a fan shell, the fan shell is a square hollow frame structure made of plastics in a rotational moulding forming manner, and a circular inner cavity which rotates along blades of the fan is arranged in the middle of the square frame structure. The fan is durable, reduces cost and is safe and reliable.

Description

[technical field] [0001] The invention relates to the technical field of heat dissipation in poultry houses, in particular to a fan used in animal husbandry and a production method thereof. [Background technique] [0002] As we all know, it is very important to choose a suitable environment for efficient breeding of beef and milk cattle. In order for cattle to grow in a good environment, it is generally required that the cattle farm environment should maintain a suitable temperature and air flow. Therefore often all need to be provided with fan to make cattle body feel cool in cattle farm. [0003] The fan installed in the cattle farm in the prior art is usually only fixed at a certain angle, and then blows air to one side of the cattle, but the other side of the cattle body cannot blow the wind all the time, resulting in uneven cooling of the cattle body. If it is necessary to blow the wind on both sides of the cattle body, it is necessary to install two fans at the same ...

Problems solved by technology

[0003] In the prior art, the fan installed in the cattle farm is usually only fixed at a certain angle, and then blows air on one side of the cattle, but the other side of the cattle body cannot blow the wind, resulting in uneven cooling of the cattle body

If it is necessary to blow the wind on both sides of the cattle body, it is necessary to install two fans at the same time, blowing on both sides of the cattle body respectively, which will increase the cost of raising cattle, which is not economical and practical; secondly, the fans on the market are generally There is no thermal relay, and the thermal relay will actively cut off the power supply when the motor is overheated, while the fan without a thermal relay cannot cut off the power supply when the motor is overheated, which is very dangerous in daily use and not safe and reliable; Fans are mainly made of iron-cased fans. Iron-cased fans are easily corroded due to their materials. They are not suitable for use in humid and harmful substances. They are not easy to clean and maintain in the future and are prone to leakage. Therefore, the life of iron-cased fans is short. , high cost, and unsafe, and hollow plastic products often cannot bear force on both arms at the same time, so as to avoid over-extrusion from destroying the mechanical balance and causing uneven distribution of external forces, so that the product has no relative stability
