A threshing drum has a cylindrical exterior, and a cuttings intake end having a seating surface. A helical auger flight, affixed to the cylindrical exterior of the threshing drum at the cuttings intake end, extends helically outward from the cylindrical exterior of the threshing drum from the inner edge to the outer edge and rearward from the leading extremity adjacent to the seating surface to the trailing extremity. The outer face faces forwardly toward the cuttings intake end. The inner face faces rearwardly away from the cuttings intake end. A wear plate includes a front extremity having a nose. The wear plate is connected to the inner face of the helical auger flight, the front extremity extends forwardly of the leading edge of the helical auger flight, and the nose of the wear plate is in direct contact against the seating surface of the cuttings intake end.

A harvest weighing mechanism utilizes a variable speed conveyor comprised of evenly spaced solid rods such that marketable product is suspended on the rods while small foreign material falls between the rods. The product moves at the same velocity as the conveyor until discharged and directed into an impact plate attached to an impact sensor. As the product collides with the impact plate the resultant deflection of the impact plate is converted to an electronic signal which is sent to a control box which uses an algorithm to convert radial velocity to linear velocity and through laws of energy conservation determines the weight of the product required to cause the deflection measured by the impact sensor.

A harvester lifts plant material and usable product off the ground using a header to create one or more distinct ribbons of material which are each fed axially into the front of rotating foraminous drums carrying stripper springs and within which a rotor with threshing springs and a screw conveyor on its outer surface is cooperatively mounted. The usable product thus separated from the plant material exits the foraminous drums to be collected and conveyed to the cleaning portion of the harvester. The product and foreign material are mechanically sized using a series of rollers and an air stream separates the product for subsequent trimming of stems therefrom. The product is then deposited on a sizing conveyor further separation and weighing.

An improved self-propelled grain harvester and threshing machine characterized by the sieves, cleaning fan and grain tank being beneath the grain harvester's threshing system which puts the center of gravity in the bottom of the machine and eliminates the need for conveying the grain throughout the machine for cleaning and to the top of the machine for storage. This configuration eliminates several clean grain conveying systems and reduces the length of the reprocess tailings elevator giving the machine a safe low profile and center of gravity when the machine is empty and the center of gravity lowers as the grain tank fills.

The present invention provides a cutter for corn threshing. The cutter is mounted on a rotary food processor with a driving device, which comprises a cylinder with one open end; a cavity disposed in the cylinder to accommodate threshed corn cobs; a cutting member disposed at the middle of the open end of the cavity; and a locking portion disposed at the other end of the cylinder and connected to the driving device of the rotary food processor in a detachable manner. The present invention further discloses a rotary food processor with this cutter. The cutter for corn threshing and the rotary food processor both have the advantages of small volume, simple operation and high practicability.

A stone trap assembly including an entrance and an exit. The entrance receives objects from a crop flow path for accumulation into the assembly during a harvesting operation, and the exit allows evacuation of the accumulated foreign objects out of the assembly during an evacuation operation. The assembly further includes a door configured to be rotatable around a first rotation axis, substantially transverse to the crop flow path, for movement along a door movement trajectory between a closed position and an evacuation position, and an impeller for forcing the accumulated foreign objects towards the exit. The impeller is configured to be rotatable around a second rotation axis, substantially transverse to the crop flow path, for movement along an impeller movement trajectory between a retracted position and an extended position closer towards the exit. The door and impeller are separately movable during at least a part of the trajectories.

A helical auger flight has an inner edge, an outer edge, an inner face, an outer face, and a leading extremity that includes a prominence and a leading edge that extends from the outer edge to the prominence. The prominence extends outward from the leading edge of the leading extremity to an outer end having an upturned jut. A wear plate is releasably connected to the inner face of the helical auger flight. The wear plate extends from the outer edge of the helical auger flight to the prominence. A front extremity of the wear plate extends forwardly of the leading edge of the helical auger flight so as to be in a shielding relationship with respect to the leading edge of the helical auger flight, and a nose of the front extremity of the wear plated is seated in direct contact against a contact surface of the jut.

A sugarcane harvester includes a basecutter assembly for cutting sugarcane stalks from sugarcane plants; a stalk-supporting mechanism for supporting the stalks of the sugarcane plants as they are being cut by the basecutters; a chopping section for chopping the sugarcane stalks into billets; and a discharge assembly for discharging the billets to a storage vehicle.
