An ambient air-to-engine fluid heat exchanger, vehicle having independent ambient air modulators are provided for both the radiator and the charge air cooler in the form of an apertured plate mounted adjacent the face of the heat exchanger and controllably slidable to bring the plate apertures in registry with the ambient air openings of the heat exchanger. For the heat exchanger for engine coolant, the front face of the heat exchanger comprises a second plate having the heat exchanger ambient air openings therein. For the charge air cooler, a second plate is unnecessary because, in an air-to-air heat exchanger, the charge air tubes are about the same width as the ambient air passages and thus the tubes can block the air flow through the modulator apertures when the plate is positioned to do so. The modulator plate is further preferably provided with integral louver portions between the apertures for channelling and streamlining the ambient air flow into the apertures and heat exchanger.

A crop harvesting platform for a windrower including a cutter, a reel, and conveyors for performing the usual steps in a crop windrowing operation. The reel includes a central shaft, driven at one end, and from which a plurality of crop-engaging bats are supported through a plurality of axially spaced sets of arms. The sets of arms are secured to the shaft by respective mounting units spaced progressively further from the driven end of the shaft. The mounting units include progressively less loadtransmitting structure per unit from the driven end to the undriven end of the reel shaft.

A grain pan assembly for a combine harvester and including a sectional grain pan proper having a fixed rear section and a hinged forward door section capable of being swung out of the general plane of the grain pan to an inclined lowered position where both sections of the grain pan, as well as other adjacent combine instrumentalities, are exposed and accessible for inspection or maintenance. A novel hinge construction at the juncture region between the two sections allows the hinged door section to be freely swung between its raised and lowered positions and also, when desired, to be lifted from its supported relationship relative to the fixed section for complete removal from the combine, thereby establishing an increased working area for grain pan removal or for purposes of repair or replacement.

An over-center toggle mounting for a moldboard plow unit embodying a spring trip mechanism having a pair of rigid toggle elements one of which is pivoted to the plow shank and the other of which is pivoted to a leaf spring on the plow frame. Cooperating abutment stops effective between one of the toggle elements and the plow frame determine the over-center position of the toggle arrangement, and consequently the normal operating earthworking position of the plow unit. The principle function of these abutment stops is to provide a pivot fulcrum to cause the toggle to release from its over-center position when the leaf spring flexes downward and forward. Rearward pressure against the plow unit results in compression and forward endwise shifting of the rigid over-center toggle arrangement, thus flexing the leaf spring in direct proportion to the magnitude of the applied plow pressure. When such pressure exeeds a predetermined maximum, the leaf spring is flexed to such a degree that the over-center condition of the toggle arrangement is positively relieved, the mechanism is tripped and the plow unit is released from its earthworking position for rearward and upward displacement incident to forward movement of the plow frame. In a modified form of the spring trip mechanism, the leaf spring is replaced by a compression spring. In either form, restoration of the plow unit to its earthworking position may be accomplished by raising the plow frame or by reversing the direction of plow movement.

Connection between bulldozer blade and push arm allowing horizontal angle of push arm with respect to bulldozer blade to change during tilting of bulldozer blade. The connection between the front end of each push arm and one end of the bulldozer blade comprises a pin carried by the bulldozer blade, a ball part mounted on the pin for sliding therealong, and a socket part mounted on the front end of the push arm and receiving the ball part in a spherical connection.

A fuel tank and hydraulic reservoir are provided with a contiguous outer wrap with spaced side walls to define an air baffle therebetween. The baffle is an open channel communicating with the engine compartment so that air flows through the channel as a result of the pressure differential created by the engine driven fan within the compartment.

A gang coupling for correlating the rotary movements of the arbor bolts of adjacent aligned disk gang sections of a disk harrow or the like. Cooperating driving and driven coupling members are mounted on the adjacent ends of the coaxial arbor bolts and embody torque transmitting fingers which overlap each other in a longitudinal direction and assume the same degree of eccentricity relative to the common axis of the arbor bolts so that they are disposed in the same cylindrical surface of revolution and thus are capable of side-by-side engagement with each other for torque-transmitting purposes but allow for circumferential lost motion in either direction through an arc of slightly less than 360*.

A combined crop-diverting shed bar and bearing protector for the rotor shaft of an axial flow-type combine. A unitary casting is fixedly secured to a structural element of the combine chassis and serves the multiple purpose of diverting the crop material, which is fed endwise against a rotating impeller, radially outwardly and away from the centrally located bearing which supports the rotor shaft, and of affording a protective shield for the bearing against the infiltration of dust or other foreign matter.
摘要:
An axial flow combine of the type embodying threshing and separating means in the form of a generally cylindrical casing within which a vaned rotor operates and which defines a threshing region and a separating region. Helical impeller vanes on the forward end of the rotor impel the crop material rearwardly into the threshing region for conduction therethrough and from thence into and through the separating region. To enhance the capacity of the casing and rotor to handle crop material, a pair of transverse sheets which extend at a slight angle to each other so that one sheet is slanted in one direction relative to the rotor axis and the other sheet is slanted in the opposite direction, cooperate to establish, in effect a front wall for the casing. These sheets cooperate with the rotating impeller vanes to receive the backlash material which issues from the impeller and direct it forwardly into the working region of the latter.
摘要:
A shielded automatic drive shaft knuckle coupler having a hub with a splined shaft-admitting bore and radial openings mounting detent pins intersecting the bore, the detent pins being held in locked position by a cam ring which is rotatable about the hub to release position whereat a releasable latch engages one of the pins. The latch is released by the engaged pin when said pin is moved out of the bore during insertion or withdrawal of the shaft to which the knuckle is coupled or to be coupled.
