Abstract
A moisturizing apparatus for use with a wind machine including a fluid manifold mounted on the wind machine to dispense fluid in the path of an air stream created by a rotating fan blade on the wind machine to humidify hot dry air blown over agricultural crops. The apparatus includes valve means and valve control means to selectively activate the valve means from a normally closed position to an open position to allow fluid under pressure to pass through the manifold into the air stream.
Claims9
The combination of a wind machine and air moisturizing means adapted for use on agricultural crops, said combination including a hollow vertical tower mounted on the ground;
- a rotatable fan mounted at the top of said tower for creating an air stream horizontally over the crops;
- power means coupled to said fan;
- gearing means on said tower and coupled with said power means for rotating said fan 360.degree. around the vertical axis of said tower;
- a fluid manifold on said tower;
- fluid supply means connected to said manifold;
- fluid nozzles on said manifold and in communication therewith to direct fluid upward into said air stream;
- said nozzles including normally closed valve means spaced between said manifold and said nozzle to control fluid flow from said manifold through said nozzles;
- camming means linked with said fan and rotatably engaging said valve means momentarily biasing said valve means open to release fluid through said nozzles;
- wherein each of said normally closed valve means includes a plunger extending radially from said valve and a cam follower at the end thereof remote said valve, and a spring biasing said plunger radially outward whereby said valve is closed.
A moisturizing apparatus to humidify air for use with an agricultural wind machine wherein said machine includes a vertical tower mounted on the ground;
- power means mounted on the ground adjacent the tower and connected to a vertical drive shaft journaled within the vertical tower and extending upwardly through the top of said vertical tower;
- a fan journaled on a fan shaft atop the tower and gear means interconnecting said drive shaft and said fan shaft whereby rotation of said fan to create an air stream horizontally over agricultural crops may be effected;
- a gear housing surrounding said gear means;
- said housing, said fan shaft and said fan rotatable 360.degree. around the vertical axis of said tower through said drive shaft;
- said moisturizing apparatus including an annular fluid manifold extending circumferentially around said tower and secured to said tower adjacent the top thereof;
- fluid supply means connected to said manifold;
- nozzles on said manifold and in fluid communication therewith to direct fluid upward into said air stream;
- valve means associated with said nozzles to control fluid flow from said manifold through said nozzles wherein said valve means each includes a normally closed valve, a plunger extending radially from said valve and a cam follower at the end thereof remote from said valve, and spring means biasing said plunger radially outward whereby said valve is closed.
