Livestock Blower Apparatus

Abstract

A livestock blower apparatus for blowing air through a flexible hose onto an animal. A pair of blower units are enclosed within an interior space of a housing. The blower units are adapted to draw air through housing inlet openings and force it through a Y-shaped conduit out through a housing outlet opening without the air coming in contact with the housing interior space. A cooling fan is provided at a housing cooling inlet opening and blows air into the housing interior space. Another cooling fan is provided at a housing cooling outlet opening and draws/blows air out from within the housing interior space. The blower units are thereby protected from the elements and noise generated by them is muffled by the housing, and the blower units are cooled for minimizing the heat that may be transferred to the air being blown onto the animal.

         21 . A blower apparatus for blowing air onto animals comprising:
 a housing defining an interior space and having first and second working air inlet openings, a working air outlet opening, a cooling air inlet opening and a cooling air outlet opening;   first and second blower units wherein each blower unit comprises a fan selectively driven by an electric motor, wherein said fan includes a fan housing having an air inlet and an air outlet and wherein said electric motor is located outside of the fan housing;   said first and second blower unit motors are located within said housing interior space whereby said blower unit motors are protected by said housing;   said first blower unit fan air inlet communicates with said housing first working air inlet opening;   said second blower unit fan air inlet communicates with said housing second working air inlet opening;   both said first blower unit fan air outlet and said second blower unit fan air outlet communicate with said housing working air outlet opening, whereby working air is drawn in through said housing first and second working air inlet openings and is forced out through said housing working air outlet; and,   wherein heat generated by said first and second blower unit motors is removed from said housing interior space by drawing cooling air into said housing interior space through said housing cooling air inlet opening and forcing the cooling air out from within said housing interior space through said housing cooling air outlet opening, and wherein the cooling air does not contact the working air within the housing interior space.   
     
     
         22 . The blower apparatus of  claim 21  wherein said first and second blower units are tangential bypass flow motor fans. 
     
     
         23 . The blower apparatus of  claim 21  further comprising an elongate flexible air hose connected to said housing working air outlet opening at one terminal end thereof and having a reduced opening nozzle at another terminal end thereof. 
     
     
         24 . The blower apparatus of  claim 21  further comprising an air filter selectively placeable over each of said housing working air inlet openings. 
     
     
         25 . The blower apparatus of  claim 21  wherein said housing comprises an integrally formed handle. 
     
     
         26 . The blower apparatus of  claim 21  wherein said housing comprises a pair of integrally formed halves secured to each other with fasteners. 
     
     
         27 . The blower apparatus of  claim 21  wherein said first and second blower units are tangential bypass flow motor fans; and, further comprising a first air filter selectively placeable over said housing first working air inlet opening and a second air filter selectively placeable over said housing second working air inlet. 
     
     
         28 . A blower apparatus for blowing air onto animals comprising:
 a housing defining an interior space and having first and second working air inlet openings, a working air outlet opening, a cooling air inlet opening and a cooling air outlet opening;   first and second blower units wherein each blower unit comprises a fan selectively driven by an electric motor, wherein said fan includes a fan housing having an air inlet and an air outlet and wherein said electric motor is located outside of the fan housing;   said first and second blower unit motors are located within said housing interior space whereby said blower unit motors are protected by said housing;   said first blower unit fan air inlet communicates with said housing first working air inlet opening;   said second blower unit fan air inlet communicates with said housing second working air inlet opening;   both said first blower unit fan air outlet and said second blower unit fan air outlet communicate with said housing working air outlet opening, whereby working air is drawn in through said housing first and second working air inlet openings and is forced out through said housing working air outlet; and,   a cooling fan drawing cooling air into said housing interior space through said housing cooling air inlet opening and forcing the cooling air out from within said housing interior space through said housing cooling air outlet opening, whereby the cooling air within the housing interior space does not contact the working air within the housing interior space and heat generated by said first and second blower unit motors is removed from said housing interior space and said first and second blower unit motors are cooled.   
     
     
         29 . The blower apparatus of  claim 28 , further comprising a Y-shaped conduit having: a first opening communicating with said first blower unit fan air outlet; a second opening communicating with said second blower unit fan air outlet; and, a third opening communicating with said housing working air outlet opening. 
     
     
         30 . The blower apparatus of  claim 28  wherein said first and second blower units are tangential bypass flow motor fans. 
     
     
         31 . The blower apparatus of  claim 28  further comprising an elongate flexible air hose connected to said housing working air outlet opening at its one terminal end thereof and having a reduced opening nozzle at its other terminal end thereof. 
     
     
         32 . The blower apparatus of  claim 28  further comprising a first air filter selectively placeable over said housing first working air inlet opening and a second air filter selectively placeable over said housing second working air inlet opening. 
     
     
         33 . The blower apparatus of  claim 28  wherein said housing comprises an integrally formed handle. 
     
     
         34 . The blower apparatus of  claim 28  wherein said housing comprises a pair of integrally formed halves secured to each other with fasteners. 
     
     
         35 . The blower apparatus of  claim 28  wherein said first and second blower units are tangential bypass flow motor fans; and, further comprising a first air filter selectively placeable over said housing first working air inlet opening and a second air filter selectively placeable over said housing second working air inlet opening. 
     
     
         36 . The blower apparatus of  claim 28 , further comprising:
 a Y-shaped conduit having: a first opening communicating with said first blower unit fan air outlet; a second opening communicating with said second blower unit fan air outlet; and, a third opening communicating with said housing working air outlet opening; and,   wherein said first and second blower units are tangential bypass flow motor fans.
