ABSTRACT:
A fluent dispensing apparatus with a timer control valve that controls the amount of fluent material dispensed into the bag or flexible container. The apparatus includes a holding tank filled with fluent material, such as sand. Formed in the tank is at least one hopper having a lower chute. A sliding gate is disposed over the lower opening of the chute which is coupled to a pneumatic arm. Movement of the pneumatic arm is coupled to an adjustable timer so that the sliding gate automatically opens and closes after a pre-determined length of time. By adjusting the timer so that after a pre-selected length of time the sliding gate is opened, the same quantity of sand may be deposited into each bag. By adjusting the timer so that a sliding gate is closed after a selected length of time, the number of bags produced over a specific period of time may be controlled. The hopper is designed for side-filling for easier filling and an optional vibrator is disposed inside the hopper to facilitate the filling process. The apparatus is constructed on a trailer so that it may be easily transported by a motor vehicle to different locations.
