Abstract: A chopper system and method for cutting crop material with a rotating first drum having first blades and a counter-rotating second drums having second blades. Blade pairs with one first blade and one second blade contact one another and cut the crop material. The blades of each blade pair contact one another for at least ten degrees of rotation. The blades can have beveled cutting edges, and the blade pairs can make bevel to bevel contact. The initial contact of the blade pairs during each rotation can form a swipe angle of 15 degrees or less. The initial contact of the blade pairs during each rotation can have the acute end of the first blade contact the second blade near the middle of the beveled edge. During each rotation, the acute end of the second blade can contact the back of the first blade.

Abstract: Sugar cane stalks are conveyed along a path passing between upper and lower chopper drums equipped with chopper blades extending lengthwise of the drums and located so that blades of one drum intermesh with those of the other so as to cut the cane stalks into billets. The cutting diameter of the blades of the upper chopper drum is greater than that of the blades carried by the lower blade resulting in the peripheral speed of the upper chopper drum being greater than that of the lower chopper drum. The cutting edge of each of the blades is defined at one side by a compound bevel with the blades being disposed on the drums so that they overlap and mesh bevel-to-bevel. The compound bevels are chosen so as to both satisfy the requirement that the blades be self-sharpening and have close to a zero timing angle.

Abstract: A method for collecting biomass, such as straw, and for producing a pyrolysis liquid, such as oil or tar, from the biomass, includes the step of collecting the biomass from a growth site, e.g. a field, by means of a mobile unit. The biomass is continuously fed into a pyrolysis apparatus accommodated by the mobile unit, as the mobile unit is moved across the growth site. While the biomass is processed in the pyrolysis apparatus, further biomass is simultaneously being collected. The pyrolysis apparatus may be a flash pyrolysis or fast pyrolysis apparatus relying on centrifugal forces for forcing biomass towards a reactive surface in a pyrolysis reactor. The mobile unit may be self-propelled.

Abstract: A machine which provides for both leaf stripping and grading can be used to process plants, such as burley tobacco plants, by continuously moving the plants in a first direction while simultaneously varying the position of the plants in a second direction relative to a defoliating apparatus. The plants may be moved horizontally through a machine by a transporter engaging the plant stalks while the vertical distance between the transporter (and thus the plants) is varied relative to the defoliating apparatus. The transporter and defoliating apparatus may be positioned at an angle to one another. Due to the changing amount of vertical distance, leaves from different sections of the plants, such as leaves at different stalk heights, can be contacted and removed at different corresponding horizontal locations in the machine. Accordingly, leaves can be graded based on the location(s) from which they are retrieved after removal.

Abstract: A baler for making rectangular crop bales has a generally horizontally disposed fore-and-aft extending baling chamber. The pickup of the baler is disposed underneath the baling chamber in line with the path of travel of a reciprocating plunger in the overhead chamber. An in-line transfer duct leads generally upwardly and rearwardly from the pickup to the bottom of the chamber. An enclosed crop flow passage is defined from a point immediately behind the pickup to a point located at the opening in the bottom of the baling chamber and presents a forwardmost cutting zone, a packing zone behind the cutting zone, and an accumulating zone behind the packing zone. Cutter apparatus within the cutting zone reduces the crop materials into smaller pieces as they flow through the cutting zone, whereupon a separate packer takes the materials from the rear side of the cutter apparatus and packs them in a downstream direction toward the accumulating zone where they form into a charge.

The rotating pneumatic tires are disposed at a predetermined angle relative to the ground surface, and the pair of pneumatic tires being rotated at a predetermined peripheral speed. The predetermined speed of the pneumatic tires is determined by and less than the rate of movement of the frame structure. The nip of the pneumatic tires thereby grasps the plant stalks for a sufficient period of time and for a sufficient distance of movement of the frame structure such that the plant stalks are pulled from the ground surface with their roots substantially attached thereto.

Abstract: A slip clutch and cutter blade apparatus for cane stalk harvesters provides a machine frame with a cutting mechanism in the form of cutter shafts powered by hydraulic motors. The cutter shafts have a plurality of knives thereon that pinch the cane therebetween as the shafts rotate to chop the cane wholestalks into billets. A flywheel is mounted on a flywheel shaft. A gearbox interfaces the flywheel and cutter blades. A flywheel clutch is used as a overload protection device for the chopper system. If overloading occurs, the flywheel slips and therefore limits the torque. The flywheel is placed on the bushing and clamped between the friction linings with the aid of the thrust plate, the cup springs, brake plate, brake plate cover, and bolts. The more the cup springs are compressed by the bolts; the higher the torque at which the flywheel slips.

The rollers are mounted on parallel shafts which are tilted so that the upper ends of the shafts are further ahead in the direction of machine travel than are their lower ends; thus, trash stems caught up between the rollers are uprooted and then presented to an array of scissoring blades whereby the stems are cut into short easily-disposable fragments.

Guides on the main frame define guideways to guide plants to be slashed, as the main frame is advanced, towards the rotary cutters which co-act, near to the rear of the guideways, with fixed cutters on the main frame. The inclined assemblies of rotary cutters, coacting with the fixed cutters, cut the branches of the bushes into small pieces before the trunks of the bushes are severed near ground level, and the lowermost of the rotary cutter blades penetrate the soil and chop the roots of the bushes.
