The invention relates to an anti-coagulation drilling fluid feeding tool. The upper portion of the outer circle of an upper joint of the tool is connected with a hanging ring in a threaded mode, and an anti-rotation mechanism is arranged on the outer circle of the upper joint. The upper portion of the anti-rotation mechanism is connected with the upper portion of the outer circle of the upper joint, and the lower portion of the anti-rotation mechanism is connected with a motor fixing cylinder. A step hole is formed in an inner cavity of the upper joint, and an electromagnet is arranged at thelower end of the step hole. A positioning ring is arranged around the outer circle of the electromagnet, and the positioning ring is fastened with the lower end of the inner cavity of the upper jointin a threaded mode. A sliding ring is arranged outside the positioning ring, and the anti-rotation mechanism is connected to the upper portion of the sliding ring. An armature is connected to the lower portion of the sliding ring, and an eccentric hole is formed in the upper portion of the upper joint. A cable sequentially penetrates through the eccentric hole, the electromagnet and the armature to be connected with a motor, and the motor is arranged in the motor fixing cylinder. A feeding cylinder body is connected between the motor fixing cylinder and a guiding shoe, and a stirring device isarranged in the feeding cylinder body. The stirring device is connected with an output shaft of the motor. Stirring blades are capable of swinging in a reciprocating mode to stir drilling fluid, so that the drilling fluid is effectively prevented from coagulating and being viscous, and traction power is provided for forward movement.
