Description

Wiper system

Technical field

The present invention relates to the technical field of development of auxiliary transport in coal mines equipment component, particularly relate to a kind of Wiper system.

Background technology

Explosion-proof rubber wheel transportation vehicle is the main assistant conveyance vehicle of underground coal mine, due to underground coal mine bad environments, has a large amount of dust granules, is attached to front part of vehicle glass, makes blurred vision; In addition, seeping water in top, tunnel, even forms the curtain of rain.Vehicle, in the process run, usually forms raindrop in the front glass of operator's compartment, makes to realize fuzzy, needs to eliminate in time with Wiper system.

Conventional Wiper system is electric wiper device, but, due to underground coal mine environmental requirement, use electric device to have the potential safety hazard arrived very much, be very restricted.

Summary of the invention

For the deficiency of above-mentioned background technology, the object of the present invention is to provide a kind of Non-follow control, the Wiper system of safe ready.

To achieve these goals, Wiper system provided by the invention, comprising: the link gearing of Wiper arm, the Wiper blade be connected on Wiper arm, handle and connecting handle and Wiper arm;

Link gearing comprises the first rotating shaft that is vertically connected at handle one end, the first rotating shaft and handle geo-stationary;

Link gearing also comprises one group of connecting rod assembly, and connecting rod assembly comprises a transverse arm and is connected to first trailing arm at transverse arm two ends, the second trailing arm, and the first trailing arm, the second trailing arm are connected with transverse arm rotation respectively; The first trailing arm other end is fixedly connected with the first rotating shaft; The second trailing arm other end is fixedly connected with by one second rotating shaft with Wiper arm bottom, the second rotating shaft and Wiper arm and the second trailing arm geo-stationary.

In some embodiments, handle is fixed on flame proof rubber tyre vehicle operator's saddle by handle bearing, and Wiper arm is fixed on outside front glass by rain brush bearing.

Wiper system provided by the invention compared with prior art, has the following advantages: its simplicity of design, compact conformation, anti-explosion safety, is convenient to remove the dust granule on glass and water droplet, successful.

Accompanying drawing explanation

Fig. 1 is the front view of the Wiper system of the first embodiment of the present invention.

Fig. 2 is the lateral plan of the Wiper system of the first embodiment of the present invention.

Detailed description of the invention

Explanation that the present invention is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 and Fig. 2 show schematically show the Wiper system provided according to one embodiment of the present invention.

As depicted in figs. 1 and 2, Wiper system provided by the invention, comprise and be fixed on the handle 2 of flame proof rubber tyre vehicle operator's saddle by handle bearing 21 and be fixed on the Wiper arm 1 outside front glass by rain brush bearing 12, inside Wiper arm 1, the side namely contacted with front glass is provided with Wiper blade.

As depicted in figs. 1 and 2, link gearing 3 connection for transmission is passed through between handle 2 and Wiper arm 1.

As depicted in figs. 1 and 2, link gearing 3 comprises first rotating shaft 31 being vertically connected at handle 2 one end, is vertically connected at the second rotating shaft 33 of Wiper arm 1 bottom and connects one group of connecting rod assembly 32 of the first rotating shaft 31 and the second rotating shaft 33.

As shown in the figure, the first trailing arm 3221, second trailing arm 3222, first trailing arm 3221, second trailing arm 3222 that connecting rod assembly 32 comprises a transverse arm 321 and is connected to transverse arm 321 two ends is rotationally connected with transverse arm 321 respectively; First trailing arm 3221 other end is fixedly connected with the first rotating shaft 31; Second trailing arm 3222 other end second rotating shaft 33 is fixedly connected with.

In this embodiment of the present invention, the first rotating shaft 31 and handle 2 geo-stationary; First rotating shaft 31 and the first trailing arm 3221 geo-stationary; First trailing arm 3221 is rotationally connected with transverse arm 321; Transverse arm 321 and the second trailing arm 3222 are rotationally connected, the second trailing arm 3222 and the second rotating shaft 33 geo-stationary; Second rotating shaft 33 and Wiper arm 1 geo-stationary.Therefore, first rotating shaft 31 is imput shaft, second rotating shaft 33 is driven shaft, the first rotating shaft 31 is rotated by handle 2 by navigating mate, the first trailing arm 3221 in connecting rod assembly 32 is with the first rotating shaft 31 and rotate to an angle centered by the first rotating shaft 31, therefore transverse arm about 321 forms displacement, the second trailing arm 3222 is driven to rotate to an angle centered by the second rotating shaft 33, second rotating shaft 33 is simultaneously rotated with the second trailing arm 3222, then Wiper arm 1 rotates with the second rotating shaft 33 and swings, remove the dust granule on glass, and water droplet.

To sum up, Wiper system provided by the invention, its simplicity of design, compact conformation, anti-explosion safety, is convenient to remove the dust granule on glass and water droplet, successful.
