Description

Technical Field

[0001] This utility model relates to the field of mining vehicle equipment technology, specifically to an automatic cleaning device for the headlights of a mining vehicle. Background Technology

[0002] Mining cars are trackless transportation devices specifically designed and manufactured for underground mines. They are mainly used in conjunction with loaders in underground tunneling and mining operations. The car lights serve a dual purpose of illumination and warning during operation, providing road illumination in dim or dark mine environments, helping drivers identify track conditions, obstacles, and tunnel structures, and ensuring safe driving.

[0003] Existing technology, such as the announcement number "CN220321123U", relates to the field of automotive parts technology and discloses a self-cleaning automotive headlight, including a headlight, a diffuser plate, a brightness enhancement film, a back plate, a side pillar, a mounting box, a lead screw, an arc plate, a brush, a power port, and a fixing port. The brightness enhancement film is disposed on the front of the diffuser plate, and the diffusion film is disposed on the back of the diffuser plate. The front of the back plate is fixedly connected to the back of the diffuser plate. One side of the side pillar is fixedly installed to the diffuser plate. The mounting box is fixedly installed on the bottom of the outer wall of the side pillar. A lead screw is provided on the top of the mounting box, and an arc plate is installed at the bottom of the lead screw. A brush is installed on the back of the arc plate. When the outer surface of the headlight becomes dirty, the starter motor cylinder drives the lead screw to rotate, causing the arc plate to move. The brush cleans the dust from the headlight. After sliding to the bottom of the headlight, the lead screw can rotate in the opposite direction, causing the arc plate to move to the top of the headlight, achieving a convenient cleaning effect.

[0004] However, current self-cleaning automotive headlights have the following problems: 1) The headlights are located at the top and bottom, making them prone to obstructing the light source; 2) They are not easy to thoroughly clean when removing damp mud and dust. Therefore, we propose an automatic cleaning device for mining truck headlights. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing cleaning equipment easily blocking the light source and being difficult to clean wet mud and dust, and to provide an automatic cleaning device for mine car lights.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] An automatic cleaning device for the headlights of mining vehicles, such as Figures 1-3 As shown, the vehicle includes a front end 1, on which a headlight body 11 is fixedly mounted. A lamp cover 12 is fixedly mounted on the outer wall of the headlight body 11. A dust removal device 2 is provided on the bottom outer wall of the front of the front end 1. The dust removal device 2 includes a servo motor 21, which is fixedly mounted on the inner wall of the front of the front end 1. A rotating shaft 22 is fixedly mounted on the output end of the servo motor 21. A dust removal shell 23 is fixedly mounted on the outer wall of the rotating shaft 22. A sliding seat 24 is slidably mounted on the inner wall of the dust removal shell 23. A cleaning brush 25 is fixedly mounted on the sliding seat 24 near the inner wall of the front end 1. The cleaning brush 25 is at a certain distance from the headlight body 11.

[0021] The servo motor 21 is started by the control lever in the cab of the front of the vehicle 1. The dust removal shell 23 is shaped like a Z. The cleaning brush 25 has flexible bristles, and the headlight body 11 is located on the movement trajectory of the cleaning brush 25.

[0022] When the mine car's headlights are in use, the lampshade 12 provides protection for the headlight body 11 as the mine car travels through the mine. However, the surface of the lampshade 12 is often covered with impurities such as mud and dust, which affects the normal illumination of the headlight body 11. When the personnel find that the headlight light has become dim, they operate the control lever in the cab of the car head 1 to start the servo motor 21. The output end of the servo motor 21 drives the rotating shaft 22 to rotate counterclockwise. The rotating shaft 22 drives the dust removal shell 23 to rotate counterclockwise. The dust removal shell 23 drives the sliding seat 24 to rotate counterclockwise. The sliding seat 24 drives the cleaning brush 25 to rotate counterclockwise. The cleaning brush 25 wipes the dust on the outer wall of the headlight body 11 upwards, effectively removing impurities from the surface of the lampshade 12, restoring the light transmittance of the headlight body 11, and ensuring the lighting brightness, thereby ensuring the safe driving and operational efficiency of the mine car in the mine. Example

[0023] This embodiment, based on embodiment 1, specifically includes the following:

[0024] like Figure 3 As shown, the dust removal device 2 also includes a sliding rod 26, a ball bearing 27, a mounting rod 28, a triangular protruding arc plate 29, and a spring 210. The sliding rod 26 is fixedly installed at one end of the sliding seat 24 near the servo motor 21. The ball bearing 27 is rolled on the inner wall of the sliding rod 26 away from the cleaning brush 25. The mounting rod 28 is fixedly installed on the outer wall of the front of the vehicle 1 near the bottom of the servo motor 21. The triangular protruding arc plate 29 is fixedly installed on the outer wall of the mounting rod 28. The spring 210 is disposed between the dust removal housing 23 and the end of the sliding seat 24 away from the servo motor 21.

[0025] The sliding rod 26 is installed through and slidably mounted on the outer wall of the dust collector 23 near the servo motor 21. The triangular protrusion arc plate 29 is composed of several triangular protrusions, and the arc surface of the triangular protrusion arc plate 29 corresponds to the semi-arc motion trajectory of the ball 27.

[0026] In the use of this utility model's automatic cleaning device for mine car lights, the high humidity inside the mine causes dust or mud to become moist. Existing headlight cleaning devices struggle to clean the lights after this moistening of the mud or dust adheres to them. Therefore, when the sliding seat 24 drives the cleaning brush 25 to rotate upwards, the sliding seat 24 simultaneously drives the sliding rod 26 to rotate counterclockwise. The sliding rod 26 then drives the ball bearing 27 to rotate counterclockwise. As the ball bearing 27 rotates downwards, it contacts the triangular protrusion arc-shaped plate 29 on the mounting rod 28. The arc surface of the triangular protrusion arc-shaped plate 29 corresponds to the rotation trajectory of the ball bearing 27. The triangular protrusion on the triangular protrusion arc-shaped plate 29 causes the ball bearing 27 to roll along the triangular protrusion and arc surface of the triangular protrusion arc-shaped plate 29 after contact. The triangular protrusion causes the ball bearing 27 to move along the sliding seat on the sliding rod 26. The sliding seat 24 slides upwards along the inner wall of the dust collector 23, causing the cleaning brush 25 to move upwards. When it contacts the arc surface on the triangular protrusion arc plate 29, the spring 210 causes the sliding seat 24 on the sliding rod 26 to return downwards. At the same time, the sliding seat 24 causes the cleaning brush 25 to return downwards. The triangular protrusions on the several triangular protrusion arc plates 29 allow the cleaning brush 25 to move back and forth, enhancing the scraping force of the cleaning brush 25 on the surface of the lamp cover 12. This can more effectively remove stubborn wet dirt, prevent dust accumulation from affecting the lighting effect, and thus ensure the continuous clear light transmission of the vehicle headlight in the humid mine environment, further improving driving safety.
