Abstract:
A removable scraper device is described herein. The removable scraper device includes an attachment element and a socket defined by the attachment element, wherein the socket is configured to receive a post of a scraper element therein. The removable scraper device further includes a slot defined by the attachment element, wherein the slot is configured to receive a portion of a bucket of a wheeled-machine therein. The removable scraper device further includes an aperture defined by the attachment element and a bolt sized to be received within the aperture. In some embodiments of the removable scraper device, the bolt and aperture are configured to selectively press the attachment element against the bucket to removably secure the removable scraper device thereto.
Abstract:
Vehicles or implements feature walking beam assemblies each having a front wheel and rear wheel carried adjacent opposite ends of the walking beam on opposite sides of a pivot point thereof. The conventional single beam is replaced by a split beam arrangement in which front and rear beams are pivotal relative to one another by an actuator, whereby changing the angle between the front and rear beams lifts or lowers the main pivot of the walking beam in order to adjust the height of the respective side of the vehicle frame. The split walking beam can be used to adjust the tilt angle of a scraper blade or other ground working arrangement in a land leveler or other earth working machine.
Abstract:
Die Erfindung betrifft ein Planier- und/oder Räumfahrzeug (10) mit einem frontseitig, mittig bzw. zwischen wenigstens zwei Achsen und/oder heckseitig angeordneten, durch wenigstens zwei Teilabschnitte gebildeten verstellbaren Räumschild (12), dessen wenigstens zwei Räumschildflügel (12a, 12b) nach beiden Seiten einer Fahrzeuglängsachse (14) weisen und jeweils um eine gemeinsame Schwenkachse (16) oder zwei voneinander beabstandete Schwenkachsen (16) verstellbar sind, die in etwa vertikal orientiert ist/sind. Einem Mittelteil (18) des Räumschildes (12) mit einer Schwenklagerung (20) für die wenigstens zwei verstellbaren Räumschildflügel (12a, 12b) ist eine Hubeinheit (22) zur Verstellung des Mittelteils (18) in etwa parallel zur Fahrzeuglängsachse (14) zugeordnet. Jeder der wenigstens zwei Räumschildflügel (12a, 12b) ist in einem von der Schwenklagerung (20) beabstandeten Bereich mittels einer Koppelstange (24) an einem fahrzeugfesten Teil verankert. Die Erfindung betrifft zudem verstellbares Planierschild (12) für eine solche Räumvorrichtung (10).
Abstract:
A method, system, and non-transitory computer-readable storage medium for calibrating an implement actuation sensor (220) of a machine (100) are disclosed. The method may include calculating a first elevation value of an implement (102) of the machine in a gravity reference frame (301) of the machine. The method may further include calculating a second elevation value of a ground-engaging device (118) of the machine in the gravity reference frame of the machine. The method may further include determining a difference between the first elevation value and the second elevation value. The method may further include calibrating the implement actuation sensor based on the determined difference.
Abstract:
Earthmoving machines are provided comprising a translational chassis movement indicator, an earthmoving implement inclinometer, and an implement state estimator. The translational chassis movement indicator provides a measurement indicative of movement of the machine chassis in one or more translational degrees of freedom. The implement inclinometer comprises (i) an implement accelerometer, which provides a measurement indicative of acceleration of the earthmoving implement in one or more translational or rotational degrees of freedom and (ii) an implement angular rate sensor, which provides a measurement of a rate at which the earthmoving implement is rotating in one or more degrees of rotational freedom. The implement state estimator generates an implement state estimate that is based at least partially on implement position signals, signals from the translational chassis movement indicator and the implement inclinometer, and one or more weighting factors representative of signal noise.
Abstract:
The present invention is directed to levelling apparatus, typically as used on tractors, excavators and skid-steer vehicles, and references the levelling assembly and mounting options including directly to the existing blade of vehicles as well as other mounting arrangements. Preferred embodiments of a levelling apparatus include a blade body portion and body mounting portion connected by an arrangement of fixed and adjustable linkages, preferably hydraulic, to allow movement of the blade body portion (relative to the body mounting portion) in substantially an up and down direction, as well as rotational movement about an axis perpendicular to the general plane of an attached blade.
Abstract:
A controller (102) monitors groundspeed in an articulated machine (10) and selectively disables an automatic articulation control function when the groundspeed is at or near zero. If there is an indication that an operator may not be aware that the automatic articulation control function is active by comparing when a mode selector (110) was activated compared to a machine power cycle or an operator not being present, the automatic articulation control function may be inactivated until the mode selector (110) is toggled. If the articulated machine (10) is in neutral and the groundspeed is at or near zero, the automatic articulation control function may disabled. If the groundspeed is at or near zero but the transmission is not in neutral, the machine (10) may simply be stalled to due working conditions and the automatic articulation control function may be maintained.
