20090095662 | HARVESTING CORN COBS - A cart is towed behind a combine harvester for collecting corn cobs and includes a conveyer belt feeding into a system for separating cobs from residue to be discharged and a tank for receiving and transporting the cobs. An unload auger is provided from the tank to one side of the cart while the cart moves forward. Power for driving the cart is obtained from a chopper drive of the combine harvester. The separating arrangement includes a series of sequential blower fans for blowing air through the discharged material as it is discharged from a conveyor and into a spreading guide disperses the residue. The cobs are conveyed using a series of augers where the auger to flight distance is at least 2 inches and particularly a pair of augers feed the cobs through a front wall of the tank so as to push cobs upwardly into the tank. | 04-16-2009 |
20090104952 | TRANSPORTING CORN COBS - A cart is towed behind a combine harvester for collecting corn cobs and includes a conveyer belt feeding into a system for separating cobs from residue to be discharged and a tank for receiving and transporting the cobs. An unload auger is provided from the tank to one side of the cart while the cart moves forward. Power for driving the cart is obtained from a chopper drive of the combine harvester. The separating arrangement includes a series of sequential blower fans for blowing air through the discharged material as it is discharged from a conveyor and into a spreading guide disperses the residue. The cobs are conveyed using a series of augers where the auger to flight distance is at least 2 inches and particularly a pair of augers feed the cobs through a front wall of the tank so as to push cobs upwardly into the tank. | 04-23-2009 |
20090124309 | HARVESTING CORN COBS - A cart is towed behind a combine harvester for collecting corn cobs and includes a conveyer belt feeding into a system for separating cobs from residue to be discharged and a tank for receiving and transporting the cobs. An unload auger is provided from the tank to one side of the cart while the cart moves forward. Power for driving the cart is obtained from a chopper drive of the combine harvester. The separating arrangement includes a suction fan or a single blower fan or a series of blower fans for blowing air through material from a conveyor and into a spreading guide which disperses the residue. The cobs are conveyed using a series of augers where the auger to flight distance is at least 2 inches and particularly a pair of augers feed the cobs through a front wall of the tank so as to push cobs upwardly into the tank. | 05-14-2009 |
20090137295 | SEPARATING COBS FROM GRAIN IN A CORN HARVESTER - A combine harvester for corn is adjusted so that the threshing system maintains the grain and cobs together and there is provided a first sieve to separate the grain and cobs from residue material which is discharged from a rear of the first sieve and a second sieve to separate the grain which passes through the second sieve from the cobs which are discharged from a rear end of the second sieve. The grain is transferred to a clean grain tank and the cobs are conveyed to a tank on a towed cart. | 05-28-2009 |

20160044869 | Apparatus for Chopping and discharging Straw from a Combine Harvester - In a combine harvester comprising a threshing rotor and an internal chopper or beater behind the threshing rotor feeding into a rear straw chopper and spreader through a distribution chamber there is provided a distribution assembly mounted rearwardly of the internal chopper or beater for controlling distribution of the materials transversely of the distribution chamber. The distribution assembly includes a pair of rearwardly extending fins which are moved by a control system for operating the fins to change the distribution at the rear of the combine harvester. The fins are carried on a mounting which is translated side to side and the fins are curved in a direction longitudinally of the direction of movement of the material from the discharge. The fins are controlled in response to a plurality of sensors at spaced positions across the distribution chamber and the sensors measure crop flow at the sensor by detecting impact of crop material on the sensor. | 02-18-2016 |
20160044870 | Drive System for the Straw Chopper of a Combine Harvester - A straw chopper for a combine includes a rotor mounted in a housing with blades on a rotor for chopping the discharge material onto a material spreading assembly. The rotor is driven by a drive transmission from an output drive shaft of the drive system of the combine harvester including first a right angle gear box connected to the drive shaft, a second right angle gear box connected to the rotor and a single drive shaft communicating drive from the first gear box to the second gear box. One end of the rotor is supported by a shaft of the second gearbox carried on the combine housing. An adjustment is provided at the output shaft or at a gearbox to remotely from the cab adjust the speed of the rotor. The drive transmission includes a cogged timing belt for positive drive for increased power. | 02-18-2016 |
20160113202 | Cutting Blade - A straw chopper to be mounted at the rear discharge of a combine harvester includes a housing with a feed opening and a discharge opening with a rotor mounted in the housing for chopping and accelerating the crop materials. The rotor has a hub and a plurality of flail blade members where at least some of the blades are formed of a plate having a mounting hole through the plate for mounting on a bushing or pin of the rotor where a bearing surface of the mounting hole of the plate and not the plate surface is coated with material such as tungsten carbide or chromium carbide of a thickness less than 0.020 inches which is harder than a parent material of the plate. | 04-28-2016 |
