The bulldozer wiper is a key component to ensure construction safety during the rainy season, mainly used to remove rainwater, dust, and dirt from the windshield, ensuring clear visibility for the driver. Its operation is usually achieved through the control device inside the driver's cabin, with common gears including low speed, high speed, and intermittent mode. Some models are also equipped with a washer system, which sprays washing water with a scraping action when pressed, improving the cleaning effect
Structure and principle: Bulldozer wipers are generally composed of an electric motor, a reducer, a four-bar linkage mechanism, a wiper arm spindle, and a wiper blade assembly. Its power comes from the electric motor. The DC permanent magnet motor is integrated with the worm gear mechanical part. The worm gear mechanism plays a role in reducing speed and increasing torque. The output shaft drives the four-bar linkage mechanism, converting the continuous rotational motion of the motor into left and right swinging motion, and then driving the wiper arm and wiper blade to achieve the windshield scraping action.
Type: Depending on the driving device, it can be divided into vacuum type, pneumatic type, and electric type. Currently, electric wipers are widely used on bulldozers. In addition, it can be divided into traditional intermittent wipers and raindrop sensing wipers according to their working methods. Traditional intermittent wipers can be adjusted by the driver according to the rain and visual conditions; Raindrop sensing wipers can automatically detect the amount of rainfall through raindrop sensors and adjust the wiping frequency accordingly.
Application scenario: Mainly used for bulldozers in rainy, snowy, or dusty working environments. For example, during open-pit mining operations, if there is rain or a large amount of dust is raised by vehicle movement, it will obstruct the driver's line of sight. The wiper can promptly remove rainwater or dust from the windshield, allowing the driver to clearly observe the work ahead and ensure safety and efficiency.
Avoid exposure to sunlight and corrosion: When parked for a long time, the bulldozer should be placed in a cool place to prevent rubber parts from aging; Clean the mud, sand and gravel on the wiper blade in a timely manner after construction to avoid scratching the glass during scraping
System function testing: Before the rainy season, check the connection of the motor, wiring harness, and the water level of the washer water storage tank to ensure that the intermittent mode and water spraying function are normal, and to prevent electrical faults from affecting construction
