专利汇可以提供Discharge means for agricultural foam专利检索，专利查询，专利分析的服务。并且A group of nozzles for discharging foam to cover a surface completely, in which foam is supplied to the nozzle at right angles to the discharge direction and at a substantial distance from any side or end wall of the nozzle to promote uniform pressure and flow. In addition, an improved nozzle support has a lost motion connection to permit the nozzle to follow the surface, secured with a pin for easy changing of the lateral position, the nozzle being slidable on a pair of beams for vertical and axial adjustment. Plows are provided to cover the edges of the foam with dirt. Sideboards shelter the emerging foam from the wind until it is deposited.，下面是Discharge means for agricultural foam专利的具体信息内容。

权利要求

1. A device for dispensing a uniform blanket of a foam of liquid and gas, comprising means for generating a said foam, a delivery passage from said generating means to a nozzle, and a nozzle for discharging said uniform blanket of a foam of liquid and gas including a foam chamber comprising spaced substantially parallel top and bottom plates, said chamber having a foam opening comprising a pair of substantially parallel laterally extending lips, said chamber having closed side walls and a closed end wall, said delivery passage supplying a gas-liquid foam to said chamber substantially at right angles to said plates through a port substantially and equally spaced not less than one diameter of said passage from a side wall and the end wall and a greater distance from said lips, whereby foam is emitted at substantially equal velocities at all points along the lips.

2. The device of claim 1 wherein the chamber and the lips are arch shaped in the lateral direction.

3. The device of claim 1 wherein the upper and lower plates forming the chamber and the lips are flat.

4. The device of claim 1 wherein said delivery passage includes a laterally extending distributor having a plurality of openings into said chamber, each said opening supplying foam to said chamber at a right angle to the portion of the plates forming the chamber about the opening.

5. A nozzle for discharging a uniform blanket of a foam of liquid and gas including a foam chamber comprising spaced substantially parallel top and bottom plates, said chamber having a foam opening comprising a pair of substantially parallel laterally extending lips, said chamber having closed side walls and a closed end wall, and means supplying foam to said chamber substantially at right angles to said plates through a port substantially spaced from the side walls, the end wall, and the lips, said nozzle being provided with means attaching it to a forwardly extending beam, a vehicle, a laterally extending beam on said vehicle, and means removably fixing said forwardly extending beam in laterally adjusted position with respect to said lateral beam, said last mentioned means including a lost motion connection between said beams shaped to permit oscillation of the forwardly extending beam around the lateral beam as an axis.

6. The device of claim 5 wherein said means fixing said forwardly extending beam in laterally adjusted position includes a lateral tube attached to the forwardly extending beam and enclosing the lateral beam; and said lost motion connection includes a pin, a hole in the lateral beam, and a hole in the tube enclosing the lateral beam, one said hole being sized to receive said pin loosely and the other said hole being sized to receive said pin closely.

7. A nozzle for discharging a uniform blanket of a foam of liquid and gas including a foam chamber comprising spaced substantially paRallel top and bottom plates, said chamber having a foam opening comprising a pair of substantially parallel laterally extending lips, said chamber having closed side walls and a closed end wall, and means supplying a gas-liquid foam to said chamber substantially at right angles to said plates through a port substantially spaced from the side walls, the end wall, and the lips, and in which a flat shield substantially larger than the nozzle is held beside the nozzle in a vertical position to keep wind from disturbing the foam till it is deposited.

8. The device of claim 1 wherein one of said top and bottom plates is provided with a lateral channel open to said chamber.
