The invention discloses a drencher used for veterinary, and relates to the technical field of veterinary appliances. The drencher includes a support plate, a support frame is fixedly arranged on the support plate, a compression cylinder is vertically fixed on the support frame, A stirring device communicated with the compression cylinder through a suction
pipe is vertically fixed on the right sideof the compression cylinder, An upper tapping of that rotary shaft is provide with an external thread II and an external thread I with opposite screw directions, the bottom of the screw sleeve blockII and the screw sleeve block I are vertically fix with an expansion plate, a liquid
discharge pipe extends downward between the two expansion plates, and a spray head is installed at the low end of the liquid
discharge pipe; The drencher allows rotary stirring of the liquid
medicine to be fed by a stirring device, The
medicine liquid is uniformly mixed to ensure the full
exertion of the medicineeffect, and the expansion effect on the mouth part of the
livestock is realized through the back movement of the two expansion plates, so that the
medicine sprayed out by the spray head can enter themouth of the
livestock accurately, a good medicine injection operation is realized, and the medicine feeding quality is improved, the operation is simple and convenient, and the medicine injection efficiency is high.
