A tipping frame is provided between the two movable arms in a rotating structure. A clamping structure is provided on the tipping frame to clamp the mine car. The two ends of a second connecting rod are connected to the fixed legs B and the tipping frame by a hinged structure, respectively, to tilt the tipping frame at a certain angle so that the mine car can be unloaded.

However, each U-shaped frame has a water pipe connected to one side, making the structure relatively complex. In actual use, after the folding canopy is unfolded and folded, the water pipes are easily sheared and squeezed by the U-shaped frame, affecting their service life. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: A dustproof mine car tipping mechanism includes fixed legs A1, each with a hinged movable arm 2. A drive unit 3, a support cylinder, is mounted on one side of each fixed leg A1, with both ends hinged to the fixed legs A1 and the movable arm 2, respectively, to drive the movable arm 2 to rotate around the hinge point. A tipping frame 4 is mounted between the two movable arms 2 in a rotating manner, and a clamping structure is provided on the tipping frame 4 to clamp the mine car. A second connecting rod 6 is hinged to both ends of a fixed leg B7 and the tipping frame 4, respectively, to tilt the tipping frame 4 at a certain angle, allowing the mine car to unload. A folding canopy is connected to the drive unit 3 and opens and closes with the rotation of the movable arms 2. By setting up a folding canopy, material splashes onto workers or equipment are prevented, and dust generated can be contained within the folding canopy to prevent its spread, thus meeting environmental protection requirements. Furthermore, the folding canopy opens simultaneously with the mine car tipping and unloading, eliminating the need for a separate drive mechanism for the folding canopy and saving costs.

[0015] The drive unit 3 is connected to a folding canopy, which is located on the side away from the mine car unloading. The folding canopy opens and closes with the rotation of the movable arm 2. Specifically, the folding canopy includes a hollow frame A5, a hollow frame B8, and a dustproof net 9. The hollow frame A5 and the hollow frame B8 are connected by the dustproof net 9. The hollow frames A5 and B8 are respectively set on one side of the fixed support leg A1 with a hinged structure. Both the hollow frames A5 and B8 have several water outlets. One end of each of the hollow frames A5 and B8 is fixedly connected to a connector 11. The connector 11 has a water inlet channel 10. An internal rotating sleeve is fitted with a water inlet pipe 12. A water passage 13 is opened on the side wall of the water inlet pipe 12 inside the connector 11. The water inlet pipe 12 is connected to the mounting base 14 in a fixed structure. The mounting base 14 can be fixedly connected to the ground, mainly to ensure the stability of the water inlet pipe 12, so as to realize the rotational connection and closure of the connector 11 and the water inlet pipe 12. The water inlet pipe can realize the rotational opening of the folding tent and the unified water inlet of the hollow frame A and hollow frame B, reducing the use of water pipes and simplifying the structure. Moreover, the water pipe no longer directly contacts the hollow frame A and hollow frame B, avoiding shear damage and improving service life.

[0016] It should be noted that the driving component 3 is a hydraulic cylinder. One end of the hydraulic cylinder is hinged to the fixed outrigger A1, and the other end is hinged to the movable arm 2. A connecting piece 15 is connected to the output end of the hydraulic cylinder away from the fixed outrigger A1. The other end of the connecting piece 15 is connected to the hollow frame A5. The connecting piece 15 is a steel wire rope. The output end of the hydraulic cylinder pulls the folding tent open through the steel wire rope. A column 16 is set on one side of the folding tent, and a steering wheel 17 is set on the column 16. The steel wire rope is turned through the steering wheel 17 to facilitate the opening of the folding tent by pulling the steel wire rope. It should be noted that the maximum opening angle of the outermost hollow frame A5 of the folding tent does not exceed 90 degrees, so that the folding tent can close automatically under its own weight.

[0017] In order to refine the sprayed water flow and improve dust suppression efficiency, atomizing nozzles 18 are fixedly installed in the hollow frame A5 and hollow frame B8 at the water outlet.

[0018] It should be noted that the connector 11 is connected to the water inlet pipe 12 by a rotating structure, and when the connector 11 is rotated to the preset position, the water inlet channel 10 is connected to the water passage channel 13. That is, after the mine car is completely overturned, the folding tent can be fully opened. At this time, the water inlet channel 10 of the connector 11 of the hollow frame A5 is connected to the water passage channel 13, and the water inlet channel 10 of the connector 11 of the hollow frame B8 is connected to the water passage channel 13. When the folding tent is closed, the water inlet channel 10 of the connector 11 is blocked by the side wall of the water inlet pipe 12, and water passage no longer occurs. There is no need to set up a valve switch. The structure is simple, convenient and quick.

[0019] To prevent water leakage, a sealing ring 19 is embedded in the side wall of the water inlet pipe 12 around the water passage 13.

[0020] To prevent the hollow frames A5 and B8 from colliding with the atomizing nozzle 18, and to position the connector 11 and prevent it from moving along the water pipe axis, a retaining ring 20 is provided on the outside of the water inlet pipe 12 between the two connectors 11.

[0021] The working principle and process of this utility model are as follows: First, the mine car is clamped and fixed using a clamping structure. Then, the hydraulic cylinder 3 is activated, and the output shaft of the hydraulic cylinder 3 extends, rotating the movable arm 2 around the hinge point with the fixed support leg A1. This lifts the tilting frame 4 and the mine car. The fixed support leg B7 generates tension through the second connecting rod 6, pulling the tilting frame 4 to tilt inward, thus tilting the mine car. As the output shaft of the supporting cylinder 3 extends, the folding canopy is pulled open by the wire rope 15. With the rotation of the hollow frame A5 and the hollow frame B8, the water inlet channel 10 of the connector 11 of the hollow frame A5 is connected to the water passage 13, and the water inlet channel 10 of the connector 11 of the hollow frame B8 is connected to the water passage 13. Water flows through the water passage 13 and the water inlet channel 10 into the corresponding hollow frame A5 and hollow frame B8, respectively, and then is sprayed out through the atomizing nozzle 18 for dust suppression.
