ABSTRACT:
A spreading implement has at least one hopper, preferably with two outlet spouts at the bottom thereof. Each spout has an outlet port through which material passes and a flow control device having holes is positioned beneath each port. A group of distributor pipes is mounted below a corresponding control device at each side of the hopper and the pipes extend laterally from the implement to terminate with outlets at different distances from the hopper. The inner ends of each group of pipes adjoin an inlet nozzle formed by open pipe channels and connectors that correspond to each pipe. The channels receive material from corresponding holes in the control device and the latter can be moved via a setting device to more or less register with apertures formed in a cover plate that overlies said channels. An enclosed air chamber is formed between the spouts at the bottom of the hopper and a blower forces air through the chamber into each inlet nozzle that enters the sides of the chamber. Each nozzle together with a group of pipes is pivotable about a horizontal pivot together with a side of the air chamber to a lower position which exposes the device for cleaning. The pipes are also pivotable about an upwardly extending axis to disconnect their inner ends from their connections to the nozzle and allow the pipes to swing as a unit rearwardly if an obstacle is encountered with sufficient force to unlock a spring biased mechanism. The pipes can also be pivoted with their supports upwardly for transport. The hopper is hermetically sealed and a rotatable agitator is provided adjacent each spout to facilitate material feed to each port. The agitators and blower are turned by a p.t.o. connection at the front of the hopper. A setting mechanism that moves each flow control device separately or in common can also be connected to a throttling vane to simultaneously adjust the amount of air being forced to the pipes.
