Crop Harvester Including a Quickly Adjustable Semi-Floating, Self-Steering Cutter Head

The present invention is directed to an easily adjustable, semi-floating, self-steering cutter head for row crops. The present invention incorporates self-steering capabilities, a cut-off mechanism and a quick-adjustment into a single integral unit. Direction sensing is accomplished by utilizing a feeler arm or a set of feeler arms which follow the plant stock row or other protrusions or indentations. Forces detected by the guidance sensors are transmitted to a ring which is a part of the housing and/or shielding of the cut-off device. The steering forces may be transmitted to a steering system through a single connection. The present invention is particularly useful in harvesting tobacco

Moveable Curing Frames

Low cost, low labor, moveable, sturdy, dependable and easily covered -- is this an ideal curing structure? Can it be done? Seeking such a design is the aim of ongoing studies using the cantilever-beam concept for supporting two rails of stick tobacco on a central beam

Moveable Tobacco Curing Frames

Moveable (or portable) curing frames offer the tobacco grower another option for successfully reducing labor and costs for producing air-cured tobacco. Reducing labor and costs is essential to continuing profitable tobacco production. Two designs that use the cantilever-beam concept for supporting two rails of stick tobacco on a central beam are shown and explained in this publication. Further details of construction and covering are shown in the following drawings

Cultivating Attachment for Crop Harvester Support Vehicle

A cultivator for attachment to a crop harvester including at least one tool frame member with soil tilling tools adjustably mounted relative thereto. A shaft is provided rotatably mounted relative to a support frame of the crop harvester. An actuating member is operatively connected to the shaft and the support frame for selectively imparting rotation to the shaft. A link is operatively, pivotally connected between the tool frame member and the support frame for guiding the frame member and the soil tilling tools between a raised position out of engagement with a ground surface and a lowered position into engagement with the ground surface. A connecting member is operatively connected to the shaft and the frame member for translating rotational motion of the shaft into rotatable, vertical motion of the tool frame member and the soil tilling tools about the link pivotally mounted to the support frame to selectively raise and lower the frame member and the soil tilling tools

Two Row Crop Harvester

A two row harvesting aid including an easily adjustable, semi-floating, self-steering primary cutter head and an auxiliary second row attachment for harvesting row crops. Self-steering capabilities, a cut-off mechanism and a quick-adjustment are combined into a single integral unit on the primary harvester. Direction sensing is accomplished by utilizing a feeler arm or a set of feeler arms which follow the plant stock row or other protrusions or indentations. Forces detected by the guidance sensors are transmitted to a ring which is a part of the housing and/or shielding of the cut-off device. The steering forces may be transmitted to a steering system through a single connection. The auxiliary second row attachment includes a motor operatively connected to an auxiliary cutter head for simultaneously harvesting an adjacent row of crops

Stick Holder and Deposition Device

The present invention is directed to a device for positioning a stick relative to a harvesting aid. The stick holder mounts a stick relative to an operator positioned on a harvesting aid. The stick holder is designed to adjust the height and angle of the stick relative to the operator. In addition, a plant holding trough is provided adjacent to the stick holder to retain the harvested crops prior to a loaded stick being discharged from the stick holder

A Field Curing Structure and Mechanized Housing System for Burley Tobacco

Two deterrents to expansion of production of burley tobacco are a lack of barn room located conveniently to the tobacco fields and a lack of hired labor for harvesting and housing, In working toward a solution to these problems, engineers from the Biosystems and Agricultural Engineering Department have designed and fabricated a field curing structure with a mechanized housing system. The field curing structure has three rows of posts set in the ground to provide columnar strength for the structure. Cross members are set on top of the columns to support the tobacco when it is placed into the structure. The roofing material, which must be replaced periodically, is spun-bonded polypropylene with a black waterproof coating This material has provided three to four seasons of life as a roof covering

Transplanter Mounting Attachment for a Harvester

A transplanter mounting attachment for attachment to a crop harvester including a pivot shaft operatively connected for rotation about an axis extending longitudinally with respect to a support frame of a crop harvester. A rotating sleeve substantially orthogonally disposed with respect to the pivot shaft and rotatably mounted relative thereto. A connecting shaft substantially orthogonally disposed with respect to the pivot shaft and rotatably mounted relative thereto. At least one transplanter attaching assembly operatively connected to the rotating sleeve and being raised or lowered upon rotary motion being imparted to the rotating sleeve. Wheels are provided which are operatively connected to the connecting shaft for engaging the ground surface to support the transplanter attaching assembly. The transplanter attaching assembly is free to rotate about substantially horizontal axes which extend substantially parallel and perpendicular to the support frame of a crop harvester

Storage of Burley Tobacco in Bales and Bundles

Bales and bundles of burley tobacco were stored for seven months from spring to fall. Leaves darkened during storage at all moisture levels and stalk positions with the exception of the bottom stalk position, which darkened only slightly. There was no difference in color change and dry weight loss between burley tobacco in bales and bundles. Normal and high moisture bales and bundles were often graded as unsound because of a deviant odor caused by bacterial activity. A bale weight loss of about 8% occurred at normal moisture with the loss being divided evenly between moisture and dry weight losse
