Grain pipe valve assembly

摘要

A grain pipe valve assembly maintains a desired level of flow restriction through a grain pipe. The assembly includes a valve couplable to a downspout. The valve is positionable proximate a lower end of the downspout. The valve has a swivel gate selectively extendable into the downspout wherein the swivel gate inhibits flow of grain through the downspout. A sensor is couplable to the downspout in spaced relationship to the valve towards the upper end of the downspout to detect when backflow of grain reaches a predetermined level in the downspout. The sensor is operationally coupled to the valve wherein the swivel gate is controlled and extended into the downspout to maintain backflow of grain to the predetermined level in the downspout.

主权项

1. A grain pipe valve assembly comprising:
a grain elevator having an elevator throat, a bottom end and a top end; a downspout having an upper end coupled to said top end of said grain elevator wherein said downspout is configured to deliver grain from said top end of said grain elevator through said elevator throat into said downspout to and out of a lower end of said downspout; a valve coupled to the downspout, said valve being positioned proximate said lower end of said downspout, said valve having a swivel gate selectively extendable into said downspout wherein said swivel gate inhibits flow of grain through said downspout; a sensor coupled to said elevator throat, said sensor being positioned in spaced relationship to said valve towards said upper end of said downspout to detect when backflow of grain reaches a predetermined level in said elevator throat, said sensor being operationally coupled to said valve wherein said swivel gate extends into said downspout to maintain backflow of grain to the predetermined level in said downspout.
