  • Patent number: 11152164
    Abstract: A lock-out pinion can be coupled to a center sump control shaft to rotate therewith. A lock-out slide can include a rack and a blocking cover. A lock-out guide can be coupled to the sump control housing and can form a guide channel. The lock-out slide can be received in the guide channel with the lock-out pinion drivingly coupled to the rack to move the lock-out slide along the guide channel from a lock-out position in which the blocking cover prevents rotation of the intermediate sump control shaft with the driving handle, to an unlocked position in which the blocking cover permits rotation of the intermediate sump control shaft with the driving handle, in response to manual rotation of the center sump control shaft in the center sump opening direction.

  • Patent number: 11066256
    Abstract: An unload conveyor and a sweep conveyor can be positioned below and above a floor of the grain bin, respectively. A below floor gearbox and an above floor gearbox can be positioned below and above a sloped wall, respectively, of a sump. The sloped wall can be designed to shed grain toward a sump basin. A coupling shaft can extend through a non-circular sump shaft aperture in the sloped wall to couple the below floor gearbox to the above-floor gearbox. The coupling shaft can extend vertically. A pair of seal cover plates can form a horizontal wall extending perpendicular to the coupling shaft. The horizontal wall can have a circular sealing aperture therein and through which the coupling shaft extends. A washer can be provided adjacent the circular sealing aperture that can be free to move laterally with wobbling of the coupling shaft.

  • Patent number: 11066247
    Abstract: A gearbox below a grain bin floor can have a shift coupling movable between a drive position and a neutral position. A control rod can be axially movable between a corresponding drive position and a corresponding neutral position. A pair of biasing members can be operably positioned between the control rod and the shift coupling to bias the shift coupling in opposite directions. The opposite biasing forces of the biasing members can act against each other to bias the control rod into the neutral positioning recess to retain the external shift coupling and the control rod in the neutral position and the corresponding neutral position, respectively. The opposite biasing force of the biasing members can bias the control rod into the drive positioning recess to retain the external shift coupling and the control rod in the drive position and the corresponding drive position, respectively.

  • Patent number: 11039604
    Abstract: This invention relates to laying nest having a rack drive expulsion system. As disclosed herein, the invention preferably comprises a laying nest for hens comprising a box and a rack drive floor expulsion system. The floor pivotably moves between first and second positions by virtue of a gear rack that is fixedly connected to and disposed within the box, and a gear wheel that is rotatably connected to the floor. Accordingly, the expulsion system provides for the selected removal of hens from the laying nests as desired.

  • Patent number: 10782069
    Abstract: A grain drying system and process includes a controller that is electronically coupled to a variable speed fan and to a heater or a heat pump to supply air through a plenum and the grain. Also coupled to the controller are ambient temperature and humidity sensors, internal plenum temperature and a humidity sensor. The controller adjusts a fan speed in combination with operating the heater or heat pump to deliver a target equilibrium moisture temperature, during a first period when the ambient air is outside the equilibrium moisture target. The controller operates the fan at a minimum speed, during a second period when the ambient air is outside the equilibrium moisture target, and the controller is unable to obtain equilibrium moisture target air in the plenum in view of operational limits of the fan and the heater or heat pump.

  • Patent number: 10542731
    Abstract: A breather cap assembly is configured to be connected to a stand-tube used in a watering system. When the watering system is in normal operation, the breather cap assembly is configured to allow for air to flow between the outside the assembly and the stand-tube. The breather cap assembly also provides for structure which acts as a baffle to minimize the introduction of foreign material from outside the breather cap assembly into the stand-tube. When the watering system is in flushing operation, the breather cap assembly is configured to seal off the stand-tube in order to minimize the possibility of water leaving the stand-tube. The breather cap assembly further also provides for structure which acts as a baffle to collect and retain a majority of any water that does leave the stand-tube during a flushing operation.
