[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 invention. The specific implementation scheme of this invention is as follows:

[0036] A dustproof mine car tipping mechanism includes fixed legs A1, each with a hinged movable arm 2. A drive unit 3, a hydraulic 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, driving the movable arm 2 to rotate around the hinge point. A tipping frame 4 is mounted between the two movable arms 2, with a clamping structure for holding the mine car. A second connecting rod 6 is hinged to both ends of a fixed leg B7 and the tipping frame 4, tilting the frame 4 at a certain angle to allow 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. The folding canopy prevents material from splashing onto workers or equipment and also traps dust within it, preventing its spread and 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 and saving costs.

[0037] Specifically, the folding tent includes a preset number of hinged U-shaped frames 81, with dustproof nets 82 installed between adjacent U-shaped frames 81. A connector 22 is installed on the uppermost U-shaped frame 81, and the connector 22 is connected to the end of the output shaft of the support cylinder. The connector 22 is a steel wire rope. A column 10 is installed on one side of the folding tent, and a steering wheel is installed on the column 10. The steel wire rope is turned by the steering wheel, which facilitates the steel wire rope to pull the folding tent open.

[0038] It should be noted that a water pipe is fixedly installed on the U-shaped frame 81, and atomizing nozzles are installed at intervals on the water pipe. When the folding awning is opened, the water pipe opens, and the atomizing nozzles spray water to improve dust suppression efficiency.

[0039] Based on the above embodiments, in another embodiment, the tilting frame 4 includes a connecting shaft 41 rotatably connected to the two movable arms 2. Two parallel support rods 42 are fixedly mounted on the connecting shaft 41, and the support rods 42 are fixedly connected to the connecting shaft 41 in a vertical structure. The clamping structure includes forks 51 and jaws 52. The forks 51 are hinged to one side of the lower part of the support rods 42, and the jaws 52 are hinged to the outer side of the upper part of the support rods 42. A first connecting rod 19 is fixedly mounted on the connecting shaft 41. One end of the first connecting rod 19 is hinged to one end of the second connecting rod 6. By pulling the first connecting rod 19 and the second connecting rod 6, the connecting shaft 41 is rotated on the movable arm 2, and thus deflected.

[0040] It should be noted that the support rod 42 has a sleeve 11 and a hydraulic cylinder 12 fixedly arranged on its side wall. The hydraulic cylinder 12 is fixedly arranged on one side of the sleeve 11. The sleeve 11 has a lifting shaft 13 arranged in a rotating lifting structure. The side wall of the lifting shaft 13 has a guide groove. The sleeve 11 has a fixing pin 21 that cooperates with the guide groove. The fixing pin 21 is arranged perpendicular to the sleeve 11.

[0041] The output shaft of the hydraulic cylinder 12 is provided with a retainer 20. One side of the retainer 20 is connected to the lifting shaft 13 in the direction of rotation and can drive the lifting shaft 13 to move up and down axially. A rotating frame 14 is fixedly provided at the lower part of the lifting shaft 13. A pin 15 is fixedly provided at the lower part of the end of the rotating frame 14 away from the lifting shaft 13. The fork 51 is provided with a pin hole 16 for the pin 15 to pass through. The pin 15 can move up and down axially along the pin hole 16.

[0042] The upper part of the lifting shaft 13 is provided with a mounting base 17 in a rotating structure. The mounting base 17 can move up and down with the lifting shaft 13. The mounting base 17 is provided with a retaining ring 18 in a rotating structure, and the retaining ring 18 is hooked on the claw 52.

[0043] When the hydraulic cylinder 12 drives the lifting shaft 13 to descend, thereby causing the chuck 52 to engage with the side wall of the mine car, at the same time, under the cooperation of the guide groove and the fixing pin 21, the lifting shaft 13 drives the rotating frame 14 to deflect, thereby rotating the fork 51 to the bottom of the mine car. Through a set of mechanisms, the chuck 52 and the fork 51 are linked, achieving two goals at once, which is convenient, fast, and improves the level of automation.

[0044] Specifically, the guide groove includes a first straight groove 91, a rotating groove 92, and a second straight groove 93 connected in sequence. The included angle between the first straight groove 91 and the second straight groove 92 is 90 degrees, so as to realize the conversion of the forks into the bottom of the mine car and out of the bottom of the mine car. It should be noted that the forks on both sides realize the conversion of the forks into the bottom of the car body from the front and the rear of the mine car, respectively.

[0045] The working principle and process of this invention are as follows:

[0046] When the mine car loaded with goods moves along the rails to one side of the tipping frame 4, the hydraulic cylinder 12 is activated. The hydraulic cylinder 12 drives the lifting shaft 13, the rotating frame 14, the pin 15 and the retaining ring 18 to move downward through the retaining seat 20. When the second straight groove 93 disengages from the fixed pin 21, the rotating groove 92 contacts the fixed pin 21, and the lifting shaft 13 rotates. Through the pin 15, the fork 51 is rotated towards the bottom of the mine car and continues to move downward until the first straight groove 91 contacts the fixed pin 21. The fork 51 is fully inserted into the bottom of the mine car. At the same time, the pawl 52 engages with the upper edge of the mine car to complete the clamping operation.

[0047] Start the support cylinder 3, extend the output shaft of the support cylinder 3, rotate the movable arm 2 around the hinge point with the fixed support leg A1, lift the tilting frame 4 and the mine car, and the fixed support leg B7 generates a pulling force on the first link 19 through the second link 6. The first link 19 pulls the tilting frame 4 to tilt inward through the connecting shaft 41, thereby tilting the mine car. At the same time as the output shaft of the support cylinder 3 extends, the folding tent is pulled open through the steel wire rope 22 to fill the water pipe with water, and the water is sprayed out through the atomizing nozzle to suppress dust.

[0048] After a half-minute pause, start the support cylinder 3. The output shaft of the support cylinder 3 retracts, and the mine car is placed on the rail. The folding canopy and water pipe are closed. Start the cylinder 12 to extend the output shaft, which in turn opens the chuck 52. The forks 51 also rotate outward due to the torsional force and lean against the side of the fixed outrigger A1. The mine car continues to work, and the unloaded goods are loaded and transported by the excavator.
