Abstract
A roadside spray apparatus primarily adapted for the precision application of chemical herbicides is mounted by means of a frame support on the front bumper of a vehicle and is monitored by the driver of the vehicle using one hand to operate electrical switches connected to solenoid valves controlling the spray through nozzles mounted on a spray boom, which boom can be adjusted laterally and can be pivoted from one side of the vehicle to the other, with the nozzles attached to coil springs on the spray boom, and with an adjustable mirror and adjustable guides located on the spray apparatus in view of the driver of the vehicle.
Claims16
A spray apparatus primarily adapted for roadside spraying from a moving vehicle, comprising:
- an extended fixed frame carried at the forward end of the vehicle and within view of an operator of said vehicle,
- said frame having a lower horizontal channel member substantially parallel with and attached to the front of said vehicle,
- said lower horizontal channel member being the main support for vertical and horizontal supporting bars which vertical supporting bars are attached at their upper ends to an upper horizontal bar and which completes the fixed frame,
- said lower horizontal channel member also being the supporting member for a horizontal boom arm which is mounted on the inside of and pivots at the center of said lower horizontal channel member and may be pivoted to be positioned at either side of said vehicle,
- said arm bearing means for locking the horizontal boom arm into position on either side of said vehicle,
- said horizontal boom arm comprising permanently mounted tubular sleeves housing horizontal inner and outer telescoping boom members which are extendable and retractable laterally relative to the tubular sleeves,
- said boom members bearing spray means connected to a reservoir of spray material.
A spray apparatus for securing to the front of a moving vehicle for roadside spraying, comprising:
- a frame for securing to the front of the vehicles;
- an arm member centrally, pivotally mounted with the frame for pivoting to either side of the vehicle for spraying either side of the roadway;
- inner and outer booms individually, telescopically mounted with the arm member for pivoting with the arm member and for independent lateral extension and retraction of either boom relative to the arm member for spraying and transport of the spray apparatus;
- separate spraying means mounted with each boom for selectively spraying distinct areas;
- at least two valve means mounted outside the vehicle for individually controlling the separate spray means;
- control panel means located inside the cab of the vehicle operatively connected to the at least two valve means and actuable by the operator to selectively control the at least two valve means mounted outside the vehicle.
A spray apparatus for securing to the front of a moving vehicle for roadside spraying, comprising:
- a support frame for securing to the front of the vehicle;
- a boom arm centrally, pivotally mounted with the frame for pivoting to either side of the vehicle for spraying either side of the vehicle
- at least two separate sets of spray nozzles mounted with the outer end of the boom arm and directed to spray at least two adjacent swaths at the side of the vehicle
- mounting means securing the spray nozzles to the boom arm so that the spray nozzles will swing rearwardly upon engaging an obstacle and return to their normal position upon disengagement with the obstacle;
- said mounting means including shield means mounted with the nozzles to engage the obstacle to protect the nozzles;
- at least two separate valve means for separately supplying spraying fluid to the at least two separate sets of spray nozzles;
- control means for positioning in the cab of the vehicle so the operator of the vehicle can separately control the supply of fluid to either of the sets of nozzles to spray either of the adjacent swaths at the side of the vehicle.
