Spreader device

摘要

A material spreader having a beater bar that meters the supply of small quantities of material to the discharge opening of a material spreader hopper eliminating the need for a gate. The beater bar has one and preferably several paddles that rotate adjacent the discharge opening and as the paddle passes the opening, discharges only the amount of material on the paddle. The material spreader uses a high ratio transmission and low rpm motor to allow for extremely slow rotation of the beater bar. The motor speed can be controlled to allow very slow rotation and very small amounts of material to be discharged from the hopper. The spreader does not require a gate. The discharge of material is metered electronically.

主权项

1. A spreader device comprising:
a spreader hopper; said spreader hopper including spaced apart front and back walls, spaced apart side walls and a top and bottom; a discharge opening positioned in said back wall adjacent and above the bottom of said hopper, said discharge opening extending transverse to said hopper and generally parallel to said front and back walls; a beater bar positioned adjacent said discharge opening said beater bar including at least first and second sets of paddles said first and second sets of paddles being disposed radially upon said beater bar, and each set of paddles being in a spaced apart single row creating a gap between each paddle, said first and second sets of paddles being offset such that the first set of paddles are opposite said gap in said second set of paddles and said second set of paddles are opposite said gap in said first set of paddles, said paddles picking up and moving material to said discharge opening, said paddles providing material control by preventing material from being discharged from said bottom with said hopper without movement of said paddles; a motor and high ratio transmission operatively connected to said beater bar for rotating said beater bar; whereby said beater bar can rotate between infinitely variable speeds, with said paddles moving material to said discharge opening and providing material control.
