专利汇可以提供Liquid fertilizer applying apparatus专利检索，专利查询，专利分析的服务。并且A mobile apparatus for applying liquid fertilizer, herbicide, pesticides and the like to crops comprises a mobile chassis having a chambered fertilizer (or weed killer) containing tank and a mist producing device mounted thereon. The mist producing device includes a fan housing having rearwardly facing outlets around which are arranged nozzle mechanisms through which the liquid fertilizer is discharged. The fine jets of liquid fertilizer or weed killer are broken up into a mist or atomized condition by the high velocity streams of air and the mist is applied to the crops as the apparatus is moved through the crops to be fertilized or treaded. A foldable sectional boom is also mounted on the chassis and is selectively usable with respect to the mist producing device to thereby permit foliage feeding of the crops or the application of a weed killer to the crops in a controlled manner. The chambered tank permits fertilizer and weed killer to be applied simultaneously but obviates the need for mixing.，下面是Liquid fertilizer applying apparatus专利的具体信息内容。

权利要求

1. A mobile apparatus for applying liquid herbicide and for applying liquid fertilizer in an extremely fine mist, comprising a chassis having ground engaging wheels and having a hitch at the front end thereof, a compartmented tank mounted on said chassis and including a pair of compartments, one of which is adapted to contain liquid fertilizer therein, and the other compartment adapted to contain liquid herbicide, a mist producing device including a fan housing having an inlet and having a plurality of generally rearwardly facing cylindrical outlets, a driven fan mechanism in said housing and producing high velocity streams of air through said outlets, a plurality of groups of nozzle mechanisms arranged circumferentially around the periphery of each outlet and positioned in close proximal relation thereto, first supply and return conduits connected with said tank, first control valve means connecting said nozzle mechanisms in communicating relation with said first supply and return conduits, first pump means interposed in communicating relation with said first supply conduit to cause the liquid fertilizer to selectively flow under pressure from said tank to the nozzle mechanisms, or to be returned to the tank, the discharge orifice of each nozzle mechanism being angularly disposed with respect to the associated fan housing outlet to discharge a small jet of liquid at relatively high velocity angularly and rearwardly into the high velocity stream of air discharged by the associated housing outlet whereby said liquid fertilizer is atomized into an extremely fine mist, a foldable sectional boom mounted on said chassis adjacent the rear thereof and being foldable between an extended operative position and a folded inoperative position, said boom including a plurality of similar sections including a center section hingedly connected to outboard sections, second supply and return conduit means connecting said boom to said tank, a second control valve connecting said boom with said second supply and return conduits, to permit liquid herbicide to be supplied thereto, or to be returned to the tank, a second pump connected in communicating relation with said second supply conduit, each boom section having a plurality of outlets therein through which the herbicide or insecticide is discharged, whereby liquid fertilizer and herbicide may be selectively individually applied to the crops to be treated or the liquid fertilizer and herbicide may be simultaneously applied to the crops.

2. The apparatus as defined in claim 1 and a pluraLity of annular mounting members positioned above said tank, each mounting member being positioned adjacent but spaced radially outwardly and axially rearwardly of one of said fan housing outlets and each mounting a group of said nozzle members adjacent but axially rearwardly of one of said fan housing outlets.

3. The apparatus as defined in claim 1 and a pair of manifold lines each being positioned adjacent said groups of nozzle mechanisms and each manifold line being connected to a plurality of nozzle mechanisms of each group.
