[0002] In the mining process, a large amount of waste will be generated after the ore is processed by mineral processing. These wastes are usually called tailings. Tailings not only occupy a large amount of land resources, but also may cause pollution to the environment. Therefore, reasonable and effective tailings management has become one of the keys to the sustainable development of the mining industry. Tailings transporters, as important equipment connecting the beneficiation plant and the tailings pond, play a vital role in the safe and efficient transportation of tailings.

[0039] When in use, first push the multiple hoppers 4 to the designated position where the tailings are piled, and move the hoppers 4 on the ground using the universal wheels 5. After all the multiple hoppers 4 have moved to the designated position, the excavator will load the tailings into the multiple hoppers 4 in sequence for loading. Whenever the loading is completed in the hopper 4, the operator can drive the crawler transport vehicle 1 to move close to the hopper 4 where the loading is completed, and then control the hollow tube 3 on the crawler transport vehicle 1 to align with the positioning rod 6 on the hopper 4, and then continue to drive the crawler transport vehicle 1 close to the hopper 4 so that the positioning rod 6 on the hopper 4 is stuck in the hollow tube 3 and the notch 301, when the positioning rod 6 contacts the touch plate 802 in the notch 301, the positioning rod 6 will squeeze the touch plate 802 to move to the side close to the contact switch 804, and the first spring 803 will be compressed to make the touch plate 802 squeeze the contact switch 804, so that the contact switch 804 controls the prompt light 801 to light up, and then as the positioning rod 6 continues to be inserted into the hollow tube 3 and the notch 301, when the through hole 601 on the positioning rod 6 is completely aligned with the touch plate 802, the positioning rod 6 will be separated from the touch plate 802 in the notch 301, and then the first spring 803 will be compressed to make the touch plate 802 squeeze the contact switch 804, so that the contact switch 804 controls the prompt light 801 to light up. The spring 803 returns to its original state, and the first spring 803 drives the touch plate 802 to move to the side away from the contact switch 804 to reset, so that the touch plate 802 releases the contact switch 804, so that the contact switch 804 controls the prompt light 801 to go out. When the operator observes that the prompt light 801 goes out, the crawler transport vehicle 1 can be controlled to stop moving. At this time, the positioning rod 6 is completely inserted into the hollow tube 3 and the notch 301, so that the hollow tube 3 limits the positioning rod 6 and the hopper 4 in the vertical direction, and then the servo motor 701 drives the first gear 702 to rotate. , the first gear 702 drives the first lock plate 703 to rotate through the first tooth groove 704, so that the first lock plate 703 is stuck in the through hole 601, and then the first lock plate 703 limits the positioning rod 6 and the hopper 4 in the horizontal direction, and then the telescopic rod of the hydraulic cylinder 2 is controlled to shorten, so that the telescopic rod of the hydraulic cylinder 2 drives the hollow tube 3 to move upward, so that the hollow tube 3 drives the positioning rod 6 and the hopper 4 to move upward, and then the universal wheel 5 on the hopper 4 is separated from the ground, and then the operator drives the crawler transport vehicle 1 to move, so as to transport the tailings in the hopper 4.

[0040] After the operator drives the crawler transport vehicle 1 to transport the tailings to the designated location, the first electric push rod 1302 drives the second electric push rod 1303, the abutment plate 1304, the reduction motor 1305 and the square rod 1306 to move to the side close to the hopper 4, so that the abutment plate 1304 moves to the top of the limit frame 1205. When the square rod 1306 contacts the first winding wheel 1201, if the square rod 1306 is aligned with the square groove 1301 on the first winding wheel 1201, the square rod 1306 will enter the square groove 1301. If the square rod 1306 is not aligned with the square groove 1301 on the first winding wheel 1201, the first winding wheel 1201 will block the movement of the square rod 1306. Then, as the reduction motor 1305 continues to When the hopper 4 moves to the side close to the hopper 4, the output shaft of the reduction motor 1305 squeezes the third spring 1307 to be compressed, and then the second electric push rod 1303 drives the push plate 1304 to move downward, so that the push plate 1304 contacts the limit frame 1205, and the push plate 1304 squeezes the limit frame 1205 to move downward, and the second spring 1206 is compressed to make the limit frame 1205 release the ratchet 1202, and then under the gravity of the right baffle plate 9, the right baffle plate 9 will rotate and open, and at the same time, the right baffle plate 9 will drive the arc plate 11 and the arc frame 10 on the right side to unfold in turn. When the right baffle plate 9 rotates and opens, the right baffle plate 9 will also pull the first winding wheel 1201 and the ratchet 1202 to rotate through the first connecting rope 1203 (if the four The square rod 1306 is now located in the square groove 1301, and the first winding wheel 1201 will drive the square rod 1306 and the output shaft of the reduction motor 1305 to rotate synchronously). After the right baffle 9 is rotated and opened, the second electric push rod 1303 drives the support plate 1304 to move upward and reset, so that the support plate 1304 is separated from the limit frame 1205. At this time, the second spring 1206 returns to its original state, and the second spring 1206 drives the limit frame 1205 to move upward and reset, so that the limit frame 1205 re-jams the ratchet 1202. After that, the first electric push rod 1302 drives the second electric push rod 1303, the support plate 1304, the reduction motor 1305 and the square rod 1306 to move and reset to the side away from the hopper 4. If the square rod 1306 is located When the square groove 1301 is in the square groove 1301, the square rod 1306 is driven to leave the square groove 1301. If the square rod 1306 is not in the square groove 1301, the output shaft of the reduction motor 1305 will gradually loosen the third spring 1307. When the third spring 1307 returns to its original state, the third spring 1307 will drive the square rod 1306 to move and reset, so that the square rod 1306 is separated from the first winding wheel 1201, and then the telescopic rod of the right hydraulic cylinder 2 is controlled to extend, so that the telescopic rod of the right hydraulic cylinder 2 drives the right end of the hollow tube 3 to move downward, so that the hollow tube 3, the positioning rod 6 and the hopper 4 are in an inclined state with the left side higher and the right side lower, so that the tailings in the hopper 4 slide to the right under the action of gravity to be discharged. When the tailings slide from the hopper 4 to the right baffle 9,The arc plate 11 and the arc frame 10 on the right side will block the tailings on the right baffle plate 9 to prevent the tailings from sliding down and discharging from the front and back sides of the right baffle plate 9, so that the tailings can only slide down to the left side for discharging, so that the tailings can be accurately discharged at the designated position.

[0041] After the tailings in the hopper 4 are completely discharged, the telescopic rod of the right hydraulic cylinder 2 is controlled to be shortened, so that the telescopic rod of the right hydraulic cylinder 2 drives the right end of the hollow tube 3 to move upward, so that the hollow tube 3, the positioning rod 6 and the hopper 4 are horizontal again, and then the second electric push rod 1303, the abutment plate 1304, the reduction motor 1305 and the square rod 1306 are driven by the first electric push rod 1302 to move to the side close to the hopper 4, so that the square rod 1306 enters the square groove 1301, or the square rod 1306 does not enter the square groove 1301, the third spring 1307 is compressed, and then the reduction motor 1305 drives the square rod 1306 to reverse. If the square rod 1306 is located in the square groove 1301, the square rod 1306 is 1306 will drive the first winding wheel 1201 to reverse synchronously. If the square rod 1306 does not enter the square groove 1301, when the square rod 1306 reverses to align with the square groove 1301, the third spring 1307 returns to its original state, and the third spring 1307 drives the square rod 1306 to enter the square groove 1301, so that the square rod 1306 drives the first winding wheel 1201 to reverse synchronously. Then, as the first winding wheel 1201 reverses synchronously, the first winding wheel 1201 will drive the ratchet 1202 to reverse synchronously. At this time, the ratchet 1202 is not hindered by the limiting frame 1205 (the characteristics of the ratchet 1202 are prior art and will not be described in detail). At the same time, the first winding wheel 1201 will reel in the first connecting rope 1203, so that the first connecting rope 1203 can be reeled in. The connecting rope 1203 pulls the right baffle plate 9 to gradually reverse and close, and the right baffle plate 9 drives the arc plate 11 and the arc frame 10 on the right side to be retracted in turn. After the right baffle plate 9 is reversed and closed, the first electric push rod 1302 drives the second electric push rod 1303, the stop plate 1304, the reduction motor 1305 and the square rod 1306 to move to the side away from the hopper 4 and reset, so that the square rod 1306 leaves the square groove 1301, and then the operator drives the crawler transport vehicle 1 back to the tailings accumulation position.
