Abstract
An aggregate spreading device includes a hopper, a conveyor system disposed below the hopper, and a spreader system extending from at least one side of the aggregate spreading device and configured to receive aggregate from the conveyor system. The spreader system includes a vertical support coupled to a frame of the aggregate spreading device, a first wall extending from a first end attached to the vertical support, and a second wall extending from a second end of the first wall. A lift actuator is configured to adjust the vertical placement of the spreader system and causing the first and second walls to move vertically.
Claims16
An aggregate spreading device comprising:
- a hopper;
- a conveyor system disposed below the hopper;
- a spreader system pivotably connected to at least one side of the aggregate spreading device and configured to receive aggregate from the conveyor system;
- a lift actuator configured to adjust a vertical placement of the spreader system;
- a position actuator for pivoting the spreader system between a storage position and a deployed position;
- and
- a slope actuator configured to adjust a slope angle of the spreader system;
- wherein one or more of the lift actuator, the slope actuator, and the position actuator are configured to transition the spreader system between positions above a grade line, at the grade line, below the grade line, and tilted across the grade line.
An aggregate spreading device comprising:
- a hopper supported by a support frame;
- a conveyor system disposed below an exit opening of the hopper;
- a first spreader system pivotably connected to a first end of the support frame;
- a second spreader system pivotably connected to a second end of the support frame;
- at least one lift actuator configured to independently adjust the vertical placement of each spreader system;
- at least one position actuator configured to pivot each spreader system between a storage position and a deployed position;
- and
- at least one slope actuator configured to independently adjust the slope angle of each spreader system;
- wherein one or more of the at least one lift actuator, the at least one slope actuator, and the at least one position actuator are configured to transition each spreader system between positions above a grade line, at the grade line, below the grade line, and tilted across the grade line.
A spreader system for an aggregate spreading device, the spreader system comprising:
- a vertical support coupled to the aggregate spreading device, the vertical support having a first portion slidably engaged with a second portion;
- a first wall extending from a first end to a second end, the first end being pivotably coupled to the vertical support;
- a second wall extending from the second end of the first wall;
- a lift actuator configured to cause the first portion of the vertical support to move with the respect to the second portion of the vertical support to adjust the vertical position of the first and second walls;
- a position actuator configured to pivot the first wall between a deployed position and a storage position;
- and
- a slope actuator configured to adjust the slope angle of the first wall;
- wherein one or more of the lift actuator, the slope actuator, and the position actuator are configured to transition the first wall between positions above a grade line, at the grade line, below the grade line, and tilted across the grade line.
