The material is transported to the stacking area by the belt conveyor, uniformly layered and stacked according to the preset trajectory by the special stacking equipment, forming a regular-shaped pile.

[0041] The specific use and role of the embodiment are as follows: when the continuous stacking operation is performed on the bulk ore material, the feeding belt conveyor accurately delivers the ore to the mobile unloading vehicle 6 above the right fixed belt conveyor 5 according to the preset conveying rhythm; the mobile unloading vehicle 6 can move stably above the fixed belt conveyor 5 according to the stacking requirements, so as to ensure that the ore receiving is not missed and the ore transfer is not scattered; then the received ore is efficiently transferred to the mobile cantilever belt conveyor 2 above the right transverse mobile belt conveyor 1; the mobile cantilever belt conveyor 2, as the core stacking executive component, can realize pitch and telescopic adjustment through the cantilever structure, and uniformly and continuously deliver the ore to the specified stacking area through the continuous and stable conveying action, so as to complete the layer-by-layer accumulation of the regular material pile; the transverse mobile belt conveyor 1 moves stably along the preset track, drives the mobile cantilever belt conveyor 2 above to adjust the operation position synchronously, so as to flexibly change the stacking range and distribution form of the ore, ensure that the material pile can fully utilize the yard space, and form a pile structure with uniform density and regular contour, thereby laying a foundation for efficient subsequent heap leaching operation; after the ore heap leaching operation is completed, the crawler bucket wheel reclaimer 3 starts and moves to the side of the material pile; the material bucket wheel 302 rotates at a low speed under the drive of the driving system, accurately digs the ore in the material pile; the bottom of the discharge port of the material bucket wheel 302 is an inclined surface; after the ore enters the material bucket wheel 302, the ore will slide from the discharge port of the material bucket wheel 302 to the guide plate on the upper part of the material guide hopper 303 under the action of gravity as the material bucket wheel 302 rotates; the inclined surface of the discharge port can accurately guide the ore, so that the ore can accurately slide above the guide plate and enter the material guide hopper 303 along the guide plate; the ore slides along the inclined inner wall of the material guide hopper 303 under the action of gravity, and finally falls above the material buffer baffle 307 on both sides; after being impacted by the ore, the material buffer baffle 307 slowly swings downward around the limiting mounting seat 305; at this time, the reset spiral spring 306 connected with the material buffer baffle 307 is synchronously stretched, absorbs the impact force generated by the falling ore through the elastic deformation of the spring, and makes the ore slide stably along the inclined material buffer baffle 307 to the conveying belt above the crawler bucket wheel reclaimer 3, thereby effectively avoiding the equipment wear and material splashing caused by the direct impact of the ore on the conveying belt; meanwhile, the splash-proof baffles 304 on the front and rear sides of the material guide hopper 303 form a closed protection space, which can effectively block the ore particles that may be scattered to both sides during the sliding process, avoid the ore splashing to the outside of the conveying belt, and ensure the integrity of the material conveying; in this process, the elastic support force of the limiting support spring 311 in the guide mounting box 309 makes the sliding detection plate 310 inside the positioning mounting plate 308 always in close contact with the outer wall of the material guide hopper 303; when the material guide hopper 303 is inclined due to long-term impact of the ore, equipment vibration and other factors, the material guide hopper 303 on one side of the inclination will generate a lateral pressure on the corresponding sliding detection plate 310,The sliding detection plate 310 is forced to move outward along the inner side sliding groove of the guide mounting box 309, and the corresponding limiting support spring 311 is compressed synchronously. When the sliding detection plate 310 moves to the preset position, the outer side press switch 312 is pressed by the sliding detection plate 310 and the inner wall of the guide mounting box 309, the contact of the press switch 312 is closed, the sound and light alarm 313 connected in series with the control circuit is started, and a clear sound and light alarm signal is sent, so as to timely remind the on-site staff that the material guide hopper 303 has an inclination fault, so that the staff can quickly respond and adjust the installation angle of the material guide hopper 303, to avoid the problem of material falling, blocked conveying and the like caused by the expansion of the fault. When the ore is completely slid onto the conveying belt, the pressure on the material buffer baffle 307 disappears, the reset spiral spring 306 is contracted and reset under the action of its restoring force, the material buffer baffle 307 is swung in the reverse direction around the limiting mounting seat 305, and the limiting mounting seat 305 can accurately limit the reset stroke of the material buffer baffle 307, so that the material buffer baffle 307 always maintains the best working angle. At the same time, the positioning mounting frame 301 provides reliable support and positioning for the material guide hopper 303 through the stable bolt connection structure, effectively resists vibration and impact in the working process, reduces the inclination probability of the material guide hopper 303, and then the conveying belt of the crawler bucket wheel reclaimer 3 is started to stably convey the ore to the mobile receiving hopper 4. The ore slides along the inner wall of the mobile receiving hopper 4 to the left side of the horizontal moving belt conveyor 1, the left side horizontal moving belt conveyor 1 accurately transfers the ore to the left side of the fixed belt conveyor 5 through synchronous operation, and finally the ore is transferred to the next processing procedure by the fixed belt conveyor 5, realizing the full-process continuous operation from stacking to unstacking and transfer, and ensuring the high efficiency, stability and smoothness of the whole production process.
