When the mixing material field needs to be stacked for the first time, the control system issues an instruction, and the intelligent unloading vehicle 6 and the material distribution device 8 start synchronously and are positioned at the starting point of the mixing material field. Open to the maximum stretched state and wait for the material input; when the material is transported to the intelligent unloading truck 6, the material will be diverted to flow down through the funnel and the chute 61, and after receiving the material through the hopper 81 of the material distribution device 8, it will move along the telescopic chute After the 80 reaches the aggregate dust suppression hopper 82, the material flow gathers and decelerates and is piled into the stockyard; at the same time, the intelligent unloading vehicle 6 and the material distribution device 8 move forward synchronously and at a uniform speed on their respective tracks to ensure that the material stockpile 10 forms a uniform and regular triangle Cross-section; when the intelligent unloading vehicle 6 and material distributing device 8 arrive at the end position of the mixing material field, they stop walking and continue to keep stockpiling, while the winch 850 starts, and the material level detection device 89 detects the height of the stockpile 10, and the stockpile 10 reaches a certain level. After the height is reached, the hoist 850 retracts the telescopic chute 80 upwards to a certain height, and the intelligent unloading vehicle 6 and the material distributing device 8 adjust the reverse running speed to move and pile materials at a uniform speed; During the process, the amount of stockpiled material on the length of the unit stockpile 10 is equal, and the synchronous reciprocating speed of the intelligent unloading vehicle 6 and the material distribution device 8 should meet In the formula, v is the belt speed of the input belt conveyor 5, v1 is the walking speed of the intelligent unloading vehicle 6 and the material distributing device 8 along the material flow direction of the feeding belt conveyor, and v2 is the intelligent unloading vehicle 6 and The speed at which the distributing device 8 reverses the material flow direction of the feeding belt conveyor.

In order to achieve a good mixing effect, in addition to appropriately increasing the number of layers of the mixing pile 10, the method of "changing the starting point and delaying the fixed end point" can be used to reduce the amount of material at the end of the mixing ore during the distributing process, that is, the intelligent unloading car 6 and material distributing device 8 rise with the height of material pile 10 at the starting position, and the starting point of material pile moves forward gradually when laying each layer of material; High, when laying each layer of material, the end point of the stacking remains unchanged, and the stacking is delayed to raise the height of the stack 10 to the height of the next material layer. According to the stacking principle of the mixing process of layering and tiling above, the stacking operation of the mixing yard is completed.

When the intelligent unloading vehicle 6 or the material distributing device 8 fails, the control system issues an instruction, and the upstream batching and conveying facilities stop feeding materials. At the same time, the control system stores the current stacking position and the height of the stockpile 10, which can be detected and repaired in situ or moved. To (manually or automatically) the maintenance positions at both ends of the material yard to be inspected and repaired; when the fault of the intelligent unloading vehicle 6 or the material distributing device 8 is eliminated, according to the relevant information stored in the control system, it will automatically move to the last fault point, and will stretch The chute 80 is put into a suitable stacking height, and after the preparatory work is completed, wait for the material input to continue to complete the stacking operation.

Example 2

As shown in Figures 9 to 11, the storage shed adopts a single-span layout, with 2 input distribution systems and 1 retrieving and output system. The difference between the scheme of this embodiment and embodiment 1 is that the number of input systems is increased, the number of intelligent unloading vehicles 6 and material distribution devices 8 is set to 2, and the equipment is used as backup for each other during the stacking operation. All the other compositions and structures are the same as in Example 1. Technological process and working process are identical with embodiment 1.

Example 3

As shown in Figures 12 to 14, the storage shed adopts a double-span arrangement, with 2 input distribution systems and 2 retrieving and output systems. The single-span layout of this embodiment is basically the same as that of Embodiment 1, and the technological process and working process are the same as those of Embodiment 1. The main advantages of this embodiment are: ①meeting the technical layout requirements of multiple material piles 10; ②through the combination of small-span storage sheds, the technical layout of large-span storage sheds caused by traditional material storage equipment is changed.

This closed storage yard has very good environmental protection, energy saving, and consumption reduction effects, and can greatly reduce production and operation costs by reducing the amount of watering and material loss; the combination of intelligent unloading vehicle 6 and material distribution device 8 replaces traditional large-scale stockpiling The equipment is stacked and arranged in space, optimizing the cantilever beam structure of the original upper platform, reducing the span of the closed raw material yard, and reducing the occupied area. At the same time, the equipment is compact in structure, light in weight, small in investment, simple in operation, easy to use and maintain , can reduce engineering investment; this closed stockyard has a good effect on improving material performance stability and mixing quality in the bulk material mixing process of metallurgical and other industries; closed stockyard can greatly reduce harsh weather The impact of the environment on production operation; closed stockyards have obvious effects on production conditions, surrounding environment, and beautification of the factory area.

Wherein telescoping chute 80 is set can avoid common intelligent unloading vehicle 6 because of funnel chute opening to material pile 10 surface drop high, and the dust raising problem that produces in unloading process, can guarantee to keep equal drop operation all the time in the stacking process simultaneously. This kind of dust suppression method is a natural airtight method, no need to provide other external energy sources, no secondary pollution, energy saving and environmental protection; setting the aggregate dust suppression bucket 82 can reduce the material flow acceleration formed by the free fall of the material through the material accumulation buffer mechanism, and reduce the material flow. The secondary dust caused by the impact of the high-speed flow on the material pile 10 can reduce the wear of the material on the inner side of the aggregate dust suppression bucket 82; by reducing the size of the discharge port of the aggregate dust suppression bucket 82, the material flow can be concentrated and evenly centered, and the material flow can be reduced. Material segregation during the small stacking process, while reducing the range of material contact with air during the descending process, and inhibiting the overflow of dust inside the telescopic chute 80 . It solves the problem of increased engineering investment caused by the structural layout of the intelligent unloading vehicle 6 walking platform 4 cantilever beams in closed workshops, reduces the engineering investment, and at the same time solves the material breaking problem caused by the platform beam through the material distribution device 8 to meet the mixing and stacking process Require. Under the unified control of the control system of the operating room 62 on the machine, the intelligent unloading vehicle 6 and the material distributing device 8 can always operate synchronously, satisfying on-site debugging, manual operation on the machine or remote automatic operation, and realizing synchronous back-and-forth continuous walking and stacking, and equal drop adjustment Functions such as medium stacking, variable starting point and fixed end point stacking with delay, travel positioning, and stacking at previous fault points meet the stacking function of layered and tiled mixing yards.
