| 201 | Apparatus and method for treating top soil | US10420787 | 2003-04-23 | US20040111960A1 | 2004-06-17 | Marcia J. Smullen; James R. Smullen |
| An apparatus and method for heat treating soil with or without sunlight, and more particularly to killing weed pests by pasteurizing a top soil thereby rendering the top soil particularly suitable for planting a fresh crop therein. In one embodiment a top soil heat treatment apparatus for pasteurizing a top soil is provided, the apparatus comprises a housing, a soil heater, and a first soil mover, such as a helical screw, adapted to contact a top soil with the heat source to provide pasteurized stop soil. A method is also provided to produce a pasteurized top soil suitable for planting a crop. The method comprises the step of transferring heat energy from a soil heater to a top soil in order to produce the pasteurized top soil. The pasteurized top soil has a substantially reduced capability of growing weeds and an enhanced capability of growing a crop planted therein. | ||||||
| 202 | PULVERIZER | US10230020 | 2002-08-28 | US20040050562A1 | 2004-03-18 | Timothy J. Stevens |
| The present invention provides a pulverizer for reducing the clumpiness or aggregation of soil into clumps or clods and for screening materials, the pulverizer having a frame mounting a substantially cylindrically configured screening drum for rotation and a scoop for aiding the delivery of the material to be pulverized or screened to the screening drum. In an embodiment of the present invention, the pulverizer may be mounted as an attachment onto an appropriate power source such as a tractor or a skid-steer loader. | ||||||
| 203 | Apparatus for separating debris from topsoil | US890497 | 1997-07-09 | US5816334A | 1998-10-06 | Barry Haggerty |
| An apparatus for simultaneously separating debris from topsoil and re-spreading the debris-free soil on the ground. The apparatus consists of a conventional, earth moving tractor to which a chassis is mounted and which carries a plurality of soil treating devices in series. The chassis includes a soil carrying and conveying paddle assembly mounted across the width of its front end which scoops up the debris laden soil off the ground. A conventional, vibrating table for separating the debris from the soil is mounted across the width of the chassis, adjacent to the paddle assembly, and the debris-laden soil is deposited onto the vibrating table from the paddle assembly. Once the vibrating table has separated the debris from the soil, the soil falls through the chassis' open bottom back to the ground, and the debris is ultimately moved to a conveyor assembly. The conveyor assembly carries the debris from the vibrating table and deposits it in a collection bin mounted across the back width of the chassis. The collection bin includes an alarm system to indicate to a driver of the tractor when the bin is full, and further includes a trap door assembly in the bin's bottom which permits the driver to selectively open or close the door from the driver's compartment. Hence, the driver is alarmed as to when the bin is full, and may then drive the apparatus to a refuse dump site, remotely open the trap door assembly, and then remotely close the door and continue working. | ||||||
| 204 | Plow apparatus and method using acoustics | US688665 | 1991-04-19 | US5271470A | 1993-12-21 | Billy R. King; Walter F. Rausch |
| The plow apparatus has plow blades to break up the soil in the plowed field. The broken up soil is scooped up with scooper blades by the forward motion of the plow apparatus and then conveyed to rotating tillers. The tillers break up the soil into smaller clumps. The tilled soil is then exposed to acoustical energy provided by acoustical transducers. The acoustical energy is of a sufficiently high intensity so as to kill or destroy weed seeds and insect larvae in the soil. The soil is then returned to the ground. | ||||||
| 205 | Apparatus for breaking rock located in a field | US312830 | 1981-10-19 | US4417627A | 1983-11-29 | Josef Willibald |
| Apparatus for breaking rock found in soil, such as in a field used for farming, includes a hood-like housing. A work shaft and a drum are positioned under the hood with the work shaft preceding the drum in the normal direction of movement of the apparatus. Flail-like parts are located on the outer surface of the work shaft and travel along a circular path. Prongs are provided on the drum and also move around a circular path. The circular path of the prongs is located lower than the circular path of the flail-like parts and at their closest point the circular paths are approximately tangent to one another where rock or other material is transferred from the prongs to the flail-like parts. | ||||||
| 206 | Cotton stalk and root shredder with re-bedder | US568127 | 1975-04-14 | US4015667A | 1977-04-05 | Aldo Ruozi |
| A root and stalk shredder having a frame, a pair of longitudinally extending, parallel, power driven lifting rollers rotatably mounted on the frame and extending longitudinally parallel to a path of travel of the shredder, guide means mounted on the frame forward of the rollers in the direction of movement of the shredder for guiding stalks between the rollers, a blade assembly mounted on the frame over the rollers and operatively associated with the rollers for cutting roots and stalks lifted by the rollers, and a plow assembly mounted on the frame and provided with a fin assembly for facilitating use of the shredder to re-shape a bed being cleared. A bed re-shaping assembly is mounted at the rear end of the shredder frame for covering over shredded crop residue deflected down into the bed by a deflector shield also arranged at the rear of the shredder frame. Advantageously, a disc blade assembly is arranged at the front of the shredder frame for clearing a pathway for the plow assembly through heavy weeds, debris, and the like. The blade assembly may comprise two overlapping sets of vertically spaced blade clusters, while the lifter rollers are advantageously provided with resilient sleeves on cylindrical portions of the rollers rearward in the shredder frame. These resilient sleeves are constructed so as to form a plurality of longitudinally extending ribs which may be reinforced by rods, and the like, so as to prolong the life of the sleeves. Generally Y-shaped handles associated with wheel assemblies which movably support the frame of the shredder facilitate adjustment of the wheel assemblies in order to obtain proper leveling of the shredder frame relative to a surface being worked. In a modified embodiment of the shredder, the blade clusters may be arranged for rotation about a horizontal axis as opposed to parallel vertical axes in order to obtain finer shredding of the crop residue and to achieve adaptability of the shredder to crop beds having different row spacings. | ||||||
