Abstract

A bovine stomach tube and pump electrically driven by internal batteries and/or an external power supply. The device comprises an elongated flexible tube having an intake opening at one end and an outlet opening at the other end. The device incorporates an electrical motor and drive mechanism at one end powering a loop endless belt internal of the stomach tube for evacuating the rumen of bovines. An alternative embodiment may employ a flexible auger-type conveyor mounted for rotation in the stomach tube. The electrical drive motor may comprise an adaptation of hand-held drills utilizing rechargeable batteries or an external electrical power source. The device is designed for rapid evacuation of the rumen of a bovine.

Claims

1. An electric motor driven bovine stomach pump and tube, said tube having an overall diameter of approximately one inch, comprising:

a. an elongated flexible outer case having an intake end and a discharge end adapted to project into the esophagus of an animal, b. an intake opening constructed in the outer case adjacent the intake end, c. a discharge opening constructed in the outer case adjacent the discharge end, d. a conveyor means movably mounted internal of said outer case extending substantially the length of said outer case, said conveyor means further comprising;

1. a drive roller rotatably mounted in said outer case adjacent the said discharge opening, 2. an idle roller rotatably mounted in said outer case adjacent the said intake opening, 3. an endless flexible looped belt mounted for rotation on said drive roller and said idle roller, and 4. flexible, flared belt cups secured to said flexible looped belt, the flexible, flared belt cups being of such a configuration as to urge a fluid substance from the said intake opening to the said discharge opening, e. a bearing means supporting said conveyor means for movement in said outer case, and f. a drive means interconnected to said conveyor means for operably moving said conveyor means internal of said outer case operably moving the work product of said conveyor means from said intake opening to said discharge opening.

2. an idle roller rotatably mounted in said outer case adjacent the said intake opening,

3. The invention of claim 1 wherein said drive means comprises:

a. an electrical drive means incorporating, b. a variable speed control mechanism.

4. flexible, flared belt cups secured to said flexible looped belt, the flexible, flared belt cups being of such a configuration as to urge a fluid substance from the said intake opening to the said discharge opening, e. a bearing means supporting said conveyor means for movement in said outer case, and f. a drive means interconnected to said conveyor means for operably moving said conveyor means internal of said outer case operably moving the work product of said conveyor means from said intake opening to said discharge opening.

5. The invention of claim 1 wherein said drive means is:

a. an electrical drive means incorporating, b. a self-contained power supply.

6. The invention of claim 5 wherein said self-coNtained power supply is a rechargeable storage battery.
