Abstract
A hay conditioning unit includes drier units which utilize microwave energy to dry hay as that hay moves through a housing on a conveyor belt. Various temperature and moisture sensors are located along the path of the hay to sense the temperature and moisture of the hay so that hay can be discharged from the unit to have a precisely controlled moisture and protein level. Other controls are included to permit such state conditions to be controlled in a desired manner, and further controls are included to permit manually overriding the automatic process controls.
Claims10
A hay conditioner comprising:
- A) a chassis having a forward end and a rear end, sides connecting said forward end to said rear end, a top surface, a towing bar element connected to said forward end and having a towing vehicle attaching element thereon;
- B) a plurality of wheels rotatably mounted on said chassis;
- C) a power take-off unit connected to a vehicle which is towing said chassis;
- D) an electrical generator mounted on said chassis and connected to said power take-off unit;
- E) a hay pickup unit mounted on said chassis front end and including
- (1) a central hub rotatably mounted on said chassis,
- (2) raking tines mounted on said central hub in position to contact hay located on the ground over which said chassis moves, and
- (3) means for rotating said central hub in a direction to throw hay from the ground onto said chassis top surface;
- F) a conveyor unit mounted on said chassis and which includes
- (1) a conveyor belt extending along the chassis from adjacent to said chassis front end to adjacent to said chassis rear end,
- (2) an inlet end located near said chassis front end,
- (3) an outlet end located near said chassis rear end, and
- (4) conveyor belt drive means for moving said conveyor belt from said inlet end to said outlet end;
- G) a housing mounted on said chassis top surface adjacent to said conveyor belt and including
- (1) a first end located near said conveyor unit inlet end,
- (2) a second end located near said conveyor unit outlet end,
- (3) sides located near said chassis sides,
- (4) a top connected to said sides, and
- (5) windows defined through said housing sides;
- H) a hay conditioning unit mounted on said housing and including
- (1) a plurality of drying units mounted in said housing, each of said drying units including a magnetron oscillator,
- (2) a power source connected to said generator and to each drying unit,
- (3) a control unit connected to said power source and to said hay conditioning power unit,
- (4) a manual on/off switch connected to said hay conditioning control unit,
- (5) a temperature sensor element mounted in said housing adjacent to said conveyor belt and connected to said hay conditioning control unit, said hay conditioning control unit including circuit means connected to said conveyor belt drive means to control the speed with which said conveyor belt moves through said housing according to temperature conditions in said housing,
- (6) a humidity sensor mounted in said housing adjacent to said conveyor belt and connected to said hay conditioning control unit, said hay conditioning control unit including further circuit means connected to said conveyor belt drive means to control the speed with which said conveyor belt moves through said housing according to moisture conditions in said housing,
- (7) a manual control connected to each of said drier units, and
- (8) timer mechanism connected to said control unit and to said humidity sensor element and to said temperature sensor element.
