Pig feeder

摘要

A pig feeder of the type comprising an inverted trapezoid-shaped hopper in which the supply of feed-to-be-dosed is loaded, which is easy to adjust by means of a single control unit that acts at the same time on both edges of the lower tray, which serves as an adjusting feed dosing gate, for which purpose a synchronism bar is provided in the upper part, which further enables an accurate readout of the dosing aperture position of the feeder by means of a rotating pointer.

1. A pig feeder comprising:
a horizontally elongated hopper (2) having an inverted trapezoidal shape for receiving food for pigs to be dosed through a lower discharge outlet, a movable lower gate (9) suitable to cover a free discharge area of said lower discharge outlet, said movable lower gate (9) being supported by two vertical supports (20a, 20b) connected each to a respective farthest end of said movable lower gate, a rotary synchronism bar (11) having two eccentric pivot means (18, 24), each of said eccentric pivot means at each farthest end of said rotary synchronism bar (11), each of said eccentric pivot means being connected to one of said vertical supports so as to allow said movable lower gate (9) to move upwardly and downwardly by rotation of said rotary synchronism bar (11), a control unit (15) comprising a rotatable threaded pin (13), and a thread-following means (16) suitable to drive a rotation movement of said threaded pin (13) through one of said eccentric pivot means (18) to the rotary synchronism bar (11), wherein said rotatable threaded pin (13) has an univocal position and movement correlation with said rotary synchronism bar (11).
