ALARM SYSTEM FOR INFORMING AMOUNT OF GRAIN FILLED IN CONTAINER OR THE LIKE

摘要

PURPOSE:To provide an alarm system for informing the amount of grain filled in a container or the like, which comprises a detector element that is rotated together with a grain scattering blade when a predetermined amount of grain is filled in a container, whereby it is enabled to detect the amount of grain charged in the container over a relatively wide range and to inform it correctly. CONSTITUTION:As grain is supplied continuously into hopper 14, it is carried by lift 15 and auger 16 and dropped onto the upper surface of grain scattering blade 3. Grain thus dropped onto the upper surface of scattering blade 3 is charged into container 1 while being scattered in every direction by the rotation of blade 3. When a predetermined amount of grain is charged into the container 1, it results that detector element 4 is rotated in the manner spattering the grain located on the upper surface, whereby detector element 4 is tilted to a certain degree. By the tilting of detector element 4, micro switch is actuated and current is passed to sound buzzer.
