| 20100154692 | AGRICULTURAL IMPLEMENT FOR DELIVERING AMMONIA GAS TO SOIL - An agricultural implement for delivering ammonia gas to soil includes a soil cutting device for forming a furrow in the soil to be fertilized, a closing device trailing the cutting device for closing the furrow, and an ammonia gas delivery tube extending downwardly into the furrow between the cutting device and the closing device, and then extending rearwardly along the furrow to the closing device for delivering ammonia gas onto at least one wall of the furrow rearwardly of the trailing end of said cutting device and of the leading end of said closing device. A discharge nozzle is mounted on the trailing end of the ammonia gas delivery tube for discharging ammonia gas onto the bottom and/or sides of the furrow. The ammonia gas delivery tube and the discharge nozzle may be made of non-metallic material, such as polymeric material, to reduce or avoid freezing of soil and moisture on the implement. | 06-24-2010 |
| 20100319596 | METER PRE-COOLER FOR AMMONIA APPLICATION SYSTEM - An ammonia distribution system has an ammonia meter, and a pre-cooler heat exchanger with a reservoir located upstream of the meter and a cooling tube downstream of the meter. | 12-23-2010 |
| 20120167809 | AGRICULTURAL IMPLEMENT HAVING FLUID DELIVERY FEATURES - An agricultural implement for delivering fluid fertilizer into a furrow in the soil of an agricultural field includes a main frame, an opener device attached to the main frame for forming a furrow in the soil, a closing device having an axis of rotation and trailing the opener device for closing the furrow, and a dispensing device for delivering a fluid into the furrow. The injection device has a bottom end extending downwardly into the furrow between the opener device and the axis of rotation of the closing device, an inlet port for receiving the fluid, at least two outlet ports for discharging the fluid into different regions of the furrow, and a bifurcated passageway for conducting the fluid from the inlet port to the outlet ports. The outlet ports may be located to discharge the fluid onto or adjacent to both of the side walls of the furrow. | 07-05-2012 |
| 20120216732 | METHOD AND APPARATUS FOR APPLYING A MINIMUM FLOW OF ANHYDROUS AMMONIA AT TARGETED RATES DUE TO LIMITATIONS EXISTING IN CURRENT DISTRIBUTION/DELIVERY - The invention provides an apparatus and method for enabling at least a minimum pressure and flow rate of stored NH3 from a storage tank to knives for injection into soil, regardless of ambient temperature. A pressure sensor and control valve monitors the pressure of the NH3 flow. If the sensed pressure drops below a desired minimum, e.g., 0.5 psi, a controller drives the control valve to open and also signals ramping up of a boost pump. The boost pump pumps NH3 from the storage tank to ensure maintenance of a minimum flow rate and pressure of NH3 from the tank to the soil. The pump runs on-demand only as needed, thereby reducing power requirements when the pump is not needed to supplement NH3 tank pressure. | 08-30-2012 |
| 20130233215 | Soil Deflector Wing for Furrow Opener With Replaceable Winged Tip Body - A paired row opener has a furrowing tip arranged to be selectively supported on a body of the opener. The furrowing tip includes a knife portion and a pair of wing portions extending rearwardly and outwardly therefrom where are separable together from the opener body. A pair of deflector wings are integrally formed on the opener body above inner edges of the respective wing portions which are abutted with the opener body so as to deflect disturbed soil away from a seam between the inner edge of the wing portions and the opener body. An insulated mounting block is fastened onto a rear bracket of the opener body which receives an anhydrous ammonia delivery tube therethrough so permit optional delivery of anhydrous ammonia at a location which is insulated and spaced rearwardly from the opener body. | 09-12-2013 |
| 20140060404 | STORAGE TANK SUMP ARRANGEMENT FOR AN AGRICULTURAL IMPLEMENT - A storage tank sump arrangement for an agricultural implement. One agricultural implement includes row units configured to deliver flowable agricultural product to a field. The agricultural implement also includes a storage tank configured to hold the flowable agricultural product. The storage tank includes a first sump and a second sump. Further, the first sump is positioned adjacent to a front portion of the storage tank relative to a direction of travel and the second sump is positioned adjacent to a rear portion of the storage tank relative to the direction of travel. The agricultural implement includes a pump in fluid communication with the first sump and the second sump. The pump is configured to pump the flowable agricultural product from the storage tank to the row units. | 03-06-2014 |
| 20150144039 | ANHYDROUS AMMONIA INJECTOR FOR DISK OPENER - A disk opener includes a disk blade for creating a furrow and a closing wheel for closing it. An injection zone is defined generally below and up to slightly forward of the closing wheel. An anhydrous ammonia injector is mounted between the blade and the wheel and delivers anhydrous ammonia via a delivery tube into the furrow at an injection point within the injection zone. The injection point is also preferably centered within the furrow. | 05-28-2015 |
| 20150144040 | APPARATUS TO IMPROVE FIELD APPLICATION OF ANHYDROUS AMMONIA IN COLD TEMPERATURES - An apparatus and method to improve delivery of liquid anhydrous ammonia from a portable liquid NH | 05-28-2015 |
| 20160007524 | Anhydrous Ammonia Fertilizer Distribution Line Monitor | 01-14-2016 |
