Abstract
Abstract A method for feeding a transporting liquid flow under pressure to create a recess in soil and using the liquid flow to carry fertilizers and chemicals in the solid state to the formed recess. A device for accomplishing the method comprises a pressure system for feeding the liquid under pressure from a tank through a pipeline having a nozzle. The pipeline is placed into a mixing chamber having loading and unloading ports and communicating with a bunker containing fertilizers and agricultural chemicals. The bunker is mounted on the frame of the device. The supply and cut-off of the liquid flowing through the nozzled pipeline is effected by means of a distributing valve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
71 words
A method of soil application of fertilizers and agricultural chemicals with a high pressure jet of liquid which method comprises the steps of: forming a pear-shaped recess in the soil with the high pressure jet, said recess being formed in the zone of a plant root system; and utilizing the jet to transport the fertilizers and agricultural chemicals in a solid non-dissolved state to the recess simultaneously with the formation thereof.
Claim 2
Independent Claim
71 words
A method of soil application of fertilizers and agricultural chemicals with a high pressure jet of liquid which method comprises the steps of: forming a pear-shaped recess in the soil with the high pressure jet, said recess being formed in the zone of a plant root system; and utilizing the jet to transport the fertilizers and agricultural chemicals in a solid non-dissolved state to the recess simultaneously with the formation thereof.
Claim 3
Independent Claim
162 words
A device for effecting the method of soil application of fertilizers and agricultural chemicals comprising in combination: a framed support mounted on a mobile vehicle; a tank for containing transporting liquid mounted on said framed support; pressure means mounted on said framed support for supplying the transporting liquid under pressure from said tank through a pipeline having a nozzled terminating portion to the soil; mixing chamber means mounted on said framed support for mixing the fertilizers and chemicals with the transporting liquid and having loading and unloading ports the latter being directed towards the soil, said mixing chamber means movably accommodating said pipeline the nozzled terminating portion of which engagably rests in said unloading port; a bunker for carrying the fertilizers and agricultural chemicals disposed above said mixing chamber means and communicating therewith through the loading port thereof; distributing means mounted on said framed support for controlling the flow of the transporting liquid passing through the nozzled terminating portion of said pipeline.
Claim 4
Independent Claim
162 words
A device for effecting the method of soil application of fertilizers and agricultural chemicals comprising in combination: a framed support mounted on a mobile vehicle; a tank for containing transporting liquid mounted on said framed support; pressure means mounted on said framed support for supplying the transporting liquid under pressure from said tank through a pipeline having a nozzled terminating portion to the soil; mixing chamber means mounted on said framed support for mixing the fertilizers and chemicals with the transporting liquid and having loading and unloading ports the latter being directed towards the soil, said mixing chamber means movably accommodating said pipeline the nozzled terminating portion of which engagably rests in said unloading port; a bunker for carrying the fertilizers and agricultural chemicals disposed above said mixing chamber means and communicating therewith through the loading port thereof; distributing means mounted on said framed support for controlling the flow of the transporting liquid passing through the nozzled terminating portion of said pipeline.
Claim 5
Dependent Claim
53 words
A device according to claim 2, in which said distributing means includes a valve which is controlled by means of a probe which opens and closes said valve in response to contacts of said probe with obstacles in the process of movement of said device over the surface of the soil being treated.
Claim 6
Dependent Claim
93 words
A device as claimed in claim 2, in which said pipeline is mounted within said mixing chamber means so as to be movable along the longitudinal axis thereof and is provided with a spring one end of which rests on a split washer secured on said pipeline and the other end rests on the bottom of a cup mounted in said mixing chamber means, said pipeline closing the unloading port of said mixing chamber means under the action of said spring in the absence of flow of the transporting liquid in said pipeline.
Claim 7
Dependent Claim
61 words
A device as claimed in claim 4 in which a flap is secured to said pipeline so that its upper edge is below the loading port of said mixing chamber means, said flap being capable of moving together with said pipeline under the action of the flow of the transporting liquid thus closing the loading port of said mixing chamber means.
Claim 8
Independent Claim
31 words
A device as claimed in claims 5 in which said mixing chamber means is composed of two parts joined telescopically to provide for changing the volume of said mixing chamber means.
Claim 9
Dependent Claim
50 words
A device as claimed in claim 6 in which said mixing chamber means is provided with a casing forming an annular space to be filled with the transporting liquid supplied into said mixing chamber means through openings in its wall, said liquid being mixed with the fertilizers and agricultural chemicals.
Claim 10
Dependent Claim
34 words
A device as claimed in claim 6 in which the terminating nozzle portion of said pipeline has passages in its side walls, said passages permitting communication between said mixing chamber means and said pipeline.
