The disclosure provides for a wiper system for cleaning a surface of a sensor housing, such as a sensor housing positioned on top of a vehicle. The wiper system includes a plurality of windows spaced around a sensor housing, and a plurality of wipers positioned around the sensor housing, each of the wipers includes a wiper blade configured to clean a corresponding window of the plurality of windows. The wiper system further includes a drive system including a movable part coupled to a motor. The motor is configured to drive the drive system to simultaneously rotate the plurality of wipers around the sensor housing such that the plurality of wipers remove debris from the plurality of windows.

An agricultural harvesting machine, particularly a combine harvester or a forage harvester, has a supporting frame, a cutting mechanism, an inclined conveyor and a driver's cab. The cutting mechanism is arranged at the supporting frame by the inclined conveyor. The driver's cab is arranged at the supporting frame with the intermediary of at least one damper unit. At least one camera is arranged in an interior of the driver's cab. The camera is oriented to the cutting mechanism and/or to the inclined conveyor through a front windshield of the driver's cab. The camera is arranged in an operative area of a cleaning device of the front windshield so that a detection area of the camera can be optically acquired at least through a portion of the operative area of the cleaning device.

This technology relates to a system for clearing a sensor cover. The system may be comprised of a first wiper and second wiper configured to clear the sensor cover of debris and a motor. The motor may rotate the first wiper and the second wiper in a first direction at a first predetermined rotation rate defined at least in part by a second predetermined rotation rate of a first sensor arranged within the sensor cover. The first wiper and the second wiper may be offset by a predetermined angular distance relative to a center of the sensor cover.

A motor-powered windshield scourer for any type of a motor-powered vehicle and or motor craft. The motorized windshield scourer may have a motor propelled appendages or a singular appendage that have replaceable scouring attachments joined to the appendages. The motor that propels the appendages can be positioned anywhere on or in the motor vehicle/craft, whether under the hood, in the cabin or elsewhere. The motor driven appendages with joined scouring attachments may be mounted on the windshield of the vehicle directly opposite of the windshield wiper blades. When turned on, the motor may move the appendages with joined attachments in a side to side and/or up and down motion across the windshield. The appendages may include an unpliable metal such as: steel, titanium, tungsten, or inconel, and the scouring attachments may include nylon scouring pads or a vinyl coated mesh attached to and covering rubber or foam.

A wiper device is provided. An operating range of each of two sets of wiper arm units can be properly restricted. A first wiper arm unit is prevented from colliding with a first front pillar or a dash panel when a first output shaft of a first speed reduction mechanism has rotated beyond a first control angle, and a second wiper arm unit is prevented from colliding with a second front pillar or the dash panel when a second output shaft of a second speed reduction mechanism has rotated beyond a second control angle.

A work vehicle comprising: a cab, an inside of which is a cockpit, having a window portion; a vehicle body having a passage on a periphery of the cab; a front lateral wiper provided so as to be rotatable around a first axis and along the window portion, and rotating around a second axis that extends in a different direction with the first axis in a movement range between a normal position that is in contact with the window portion and a rising position separated from the window portion; and a passage fence extending along an outer edge of the passage. The passage fence is configured to open upward with penetrating the passage fence inwardly and outwardly, and a part of the passage fence has an opening that includes the movement range of the front lateral wiper.

A cab of a work vehicle includes a front windshield that extends in a vehicle width direction; front lateral windshields that extends diagonally rearward and is connected to both sides of the front windshield in the vehicle width direction via ridgelines, and a rear-end edge of each front lateral windshield extending in a vertical direction being gradually separated from the ridgeline of each front lateral windshield while extending downward; a front lateral wiper that is disposed so as to be rotatable around an upper axis that is disposed above each front lateral windshield and so as to be rotatable along each front lateral windshield; an upper drive device that is configured to reciprocally rotate the front lateral wiper around the upper axis between a rear position in and a front position.
