Abstract
A livestock weighing device that performs a secondary operation such as marking animals having a desired minimum weight with a visual indicia to aid sorting thereof. The weight of an animal moving across the platform actuates a cable system to move a shuttle associated with an actuator. The actuator changes condition to initiate a secondary operation, such as opening an outlet valve for a container of paint to dispense a quantity of paint onto the animal supported on the platform, when the sled is moved in a predetermined direction and the animal weighs more than the minimum required weight.
Claims4
A livestock weighing device for weighing an animal and actuating a secondary operation if the detected weight exceeds a target weight, the livestock weighing device comprising:
- a frame;
- a platform;
- first and second scale arms extending generally horizontally;
- the first scale arm pivotally connected to the frame at a first pivotal connection proximate a first end of the platform and connected to a first suspension link proximate a second end of the platform;
- the second scale arm pivotally connected to the frame at a second pivotal connection proximate a second end of the platform and connected to a second suspension link proximate a first end of the platform;
- the platform suspended from the first scale arm by a first hanger connected to the first scale arm between the first pivotal connection and the first suspension link and from the second scale arm by a second hanger connected to the second scale arm between the second pivotal connection and the second suspension link;
- a container of a marking substance, the container supported on the livestock weighing device and having an outlet through which the marking substance may be released and an outlet valve for selectively releasing the marking substance through the outlet, the outlet valve oriented for discharging the marking substance downward and toward a center of the platform;
- a trigger operably advanceable between first and second conditions;
- and
- a trip weight setting means applying a resistive force to prevent advancement of the trigger between the first and second conditions until a counteracting force corresponding to the weight of the animal supported on the platform transmitted through the first and second scale arms and the first and second suspension links, and acting in opposition to the resistive force, exceeds the resistive force and wherein when the counteracting force exceeds the resistive force the trigger advances between the first and second conditions and operably engages the outlet valve to discharge a quantity of the marking substance through the outlet for the container and downward onto a portion of the animal located at the center of the platform.

A livestock weighing device for weighing and marking an animal, the livestock weighing device comprising:
- a frame;
- a platform;
- first and second scale arms extending approximately horizontally;
- the first scale arm pivotally connected to the frame at a first pivotal connection proximate a first end of the platform and connected to a first linkage proximate a second end of the platform;
- the second scale arm pivotally connected to the frame at a second pivotal connection proximate a second end of the platform and connected to a second linkage proximate a first end of the platform;
- the platform suspended from the first scale arm by a first hanger connected to the first scale arm between the first pivotal connection and the first linkage and from the second scale arm by a second hanger connected to the second scale arm between the second pivotal connection and the second linkage;
- a balance arm pivotally connected to the frame between first and second ends, a counterweight assembly is connected to the balance arm proximate the first end thereof for providing a counterweight acting on the balance arm, the first and second linkages operably connected to the balance arm proximate the second end thereof;
- a container of a marking substance, the container supported on the livestock weighing device and having an outlet through which the marking substance may be released and an outlet valve for selectively releasing the marking substance through the outlet, the outlet oriented for discharging the marking substance downward and toward a center of the platform;
- a trigger operably connected to the balance arm;
- wherein, when the weight of an animal supported on the platform acting through the first and second scale arms and the first and second linkages exceeds the counterweight, the trigger operably engages the outlet valve to discharge a quantity of the marking substance through the outlet for the container and downward onto a portion of the animal located at the center of the platform.
