The tank body 1 is used to store food, which can be feed.

[0050] The working principle of the utility model is roughly as follows: when it is necessary to increase the height of the feeding tray 2, the first supporting leg 31 is flipped outward from between the two positioning plates 2211. During the unfolding process, the third side plate 317 cooperates with the limiting inclined surface 223 to limit the first supporting leg 31 to prevent the first supporting leg 31 from unfolding at an angle that is too large, thereby achieving the heightening of the poultry feeder. When it is necessary to further heighten the feeding tray 2, the inclined surface 322 of the second supporting leg 32 can be pulled outward until the pressing piece 324 extends outward under the restoring force of the spring 325, so that the upper end of the pressing portion 3241 of the pressing piece 324 abuts against the second end 312 of the first supporting leg 31 to limit the position, thereby preventing the second supporting leg 32 from retracting into the accommodating groove 313 under the gravity of the poultry feeder, thereby achieving the heightening of the feeding tray 2 again.

[0051] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
