Automatic feeding device for livestock breeding

The invention discloses an automatic feeding device for livestock breeding, and relates to the technical field of livestock breeding, the automatic feeding device comprises a box body, a striker plate is slidably installed on the box body in a penetrating mode, a horizontal traction assembly and a vertical traction assembly are installed at the two ends of a deflection frame respectively, and the horizontal traction assembly is used for driving an inner sliding plate to slide horizontally; the vertical traction assembly is used for driving the feeding trough to vertically slide, a connecting rod is hinged to the deflection frame, and an elastic assembly is installed between the fixing frame and the transverse rod. When the livestock feeding device is used, livestock feed put into the feeding hopper can finally fall into the feeding trough to achieve feeding operation on livestock, the feeding trough can drive the deflection frame to deflect through the vertical traction assembly, the deflection frame drives t
