发明名称 Spreader device for particulate material
摘要 A device for spreading particulate material in an elongated path at a precise predetermined height. The device comprises a front panel extending vertically from an upper opening and then extending horizontally terminating at the forward edge of a lower opening. A rear panel extends vertically from the upper opening and terminates at a lower edge located at an elevation above the lower edge of the front panel. Side panels extend vertically and are coupled to the front and rear panels. The side panels have inwardly extending shoes with lower surfaces parallel with the lower edge of the horizontal portion of the front panel. An L-shaped bar is adjustably positioned adjacent to the lower edge of the rear panel for varying the height of the particulate material to be dispensed. The L-shaped bar has a vertical portion adjustably coupled with respect to the rear panel and a horizontal portion extending rearwardly from the rear panel with the lower surface thereof determining the height of the particulate material to be spread. Attachments couple the device to a truck for pulling the device simultaneously with the dispensing of particulate material into the upper opening and from the lower opening.
