This creation is to provide a kind of trough structural improvement,Be be to the trough to keep fowls the ontology for including a preset volume and form,And one be incorporated in ontology lower end chassis constituted； Wherein,One section of support arm is extended out in the inside level side of ontology one end on the lower,To cut screw thread pipeline section in leg extremities projection downward one,And the center hold on chassis is through the hole that the permission ontology screw thread pipeline section passes through,When being set with chassis as group be as ontology be inserted in by a knob ontology downward the screw thread pipeline section of one end,And run through centre bore into chassis,Making orientation locking with a knob,Make the trough of the composition that can carry out the knob of swivel base lower end depending on poultry food amount number in use,To adjust the height between suitable ontology and chassis,So that there is trough motor-driven load number to adjust.本創作是提供一種飼料槽結構改良，是對餵養家禽的飼料槽為含括一預設容積及形態的本體、及一結合在本體下端的底盤所構成；其中，在該本體靠下一端的內側層面一側是延伸出一截支臂，以在該支臂末端朝下突伸一截螺紋管段，而在底盤的中心方位是貫穿一允許本體該螺紋管段通過的孔，作為本體在和底盤作組設時是藉一旋鈕套入本體朝下一端的螺紋管段、及貫穿入底盤的中心孔，在和一旋鈕作方位鎖固，使該組成的飼料槽在使用上能視家禽食用量多寡來旋轉底盤下端的旋鈕，以調整合宜的本體和底盤之間的高度，使得飼料槽具有機動的出料量多寡調整。
