Background

The working environment of the engineering machinery is severe, the dust is large, the noise is large, and the working condition risk is high. The operator of a working machine needs a good view to ensure the safety of its operation. Therefore, the engineering machinery is generally provided with a large windshield, and the glass in the main working visual field area is also provided with a wiper to ensure the cleanliness of the glass.

The sealing performance of the engineering machinery control room is relatively good, but the problem of poor ventilation also exists. When the room is stuffy and hot and the external working environment allows, the operator is more accustomed to opening the air window for ventilation. However, for the windshield window with the wiper, as the windshield glass is connected with the cab body into a whole through the wiper assembly, the windshield windows cannot be opened, so that the indoor ventilation effect is greatly reduced, and the riding comfort of an operator is influenced.

The prior art mainly has the following forms in the position of the windscreen wiper when the windshield is opened and closed:

(1) integrated windscreen wiper

The wiper motor, the linkage mechanism, the wiper arm, the wiper rod and the wiper blade are simultaneously arranged on the windshield glass, and the control end is connected with the motor through a wire harness. When the windshield is opened, the wiper motor moves along with the windshield glass, and the control end is fixed, so that the larger the moving distance of the windshield glass is, the longer the wire harness needs to be reserved, and the wire harness cannot be fixed and is exposed outside. The windscreen wiper is still a whole actually, only the connecting wiring harness between the control end and the windscreen wiper motor is lengthened, and the wiring harness is exposed, so that the attractiveness is poor.

(2) Jumping type windscreen wiper

The wiper motor and the linkage mechanism are fixed on the control chamber body, the wiper arm is connected with the linkage mechanism, and the wiper rod and the wiper blade are fixed on the wiper arm. The wiper blade is attached to the glass in a manner consistent with the conventional wiper blade mounting manner, except that when the wiper arm moves to the edge of the glass, the oscillating amplitude of the wiper arm exceeds the range of the glass by a current signal given by the control end, and the wiper arm slides into the fixed support along a slope outside the glass (the slope is fixed at the end of the operating chamber shell). Therefore, the wiper is separated from the glass, and the glass is not limited by the wiper and can be opened and closed. However, when the wiper needs to be reused, an operator walks out of the control room, manually puts the wiper arm on the fixed support back onto the glass again, and then starts the wiper to work through the control end, so that the operation is complex.

SUMMERY OF THE UTILITY MODEL

The purpose is as follows: in order to overcome the not enough that exists among the prior art, the utility model provides a disconnect-type windscreen wiper device solves the problem that the windscreen wiper was installed to the windscreen wiper and the problem of opening, closing and current portable windscreen wiper motor pencil hourglass not beautiful problem outward.
