[0073] Embodiment 8
[0074] The continuous mining conveying system of the embodiment has the same basic structure as that of Embodiment 7, but is different and improved in that, as shown in Figure 1 the steps are as follows:
[0075] Step one, intelligent transfer device movement: before the rock blasting, the electrical control system 23 and the hydraulic system 22 are started, the lifting wheel group 24 is withdrawn into the support on the L2 conveyor 2, so that the rotating disc II 25 contacts the mobile unloading hopper 4; the steering support wheel group 21 moves away from the blasting point, the L2 conveyor 2 rotates around the mobile unloading hopper 4 in the direction away from the blasting point under the driving of the steering support wheel group 21, and the L1 conveyor 1 moves backward at the same time; the mobile crushing station moves together with the L1 conveyor 1 to a safe distance outside the blasting point;
[0076] Step two, intelligent transfer device reset: after the blasting is completed, the L1 conveyor 1 is moved to the front of the stone pile by the mobile crushing station; the L2 conveyor 2 can rotate around the mobile unloading hopper 4 under the driving of the L1 conveyor 1 and move back to the working area, and the equipment does not require separation during movement;
[0077] Step three, intelligent transfer device work: after the equipment is reset, the lifting wheel group 24 under the L2 conveyor 2 is lowered to contact the ground, the tail of the L2 conveyor 2 is lifted, and the unloading port at the tail is lifted to above the feeding port of the mobile unloading hopper 4; the electrical control system 23 is arranged on the L2 conveyor 2 and is programmed by WebAccess to realize remote control and compatibility with the mobile crushing station, so as to realize intelligent control of the entire intelligent transfer device.
[0078] Step four, start the displacement device 5: when the material through the feed port 41 on the mobile discharge hopper 4 falls into the head of the displacement device 5, the material is transported forward under the drive of the conveyor belt I 50.
[0079] Example 9
[0080] The displacement and stacking method of the conveying system for continuous mining in this embodiment is basically the same as that in example 8, and the difference and improvement is that: Figure 9 As shown in the figure, the stacking step is:
[0081] Step one, start the horizontal swing mechanism 74: the horizontal swing mechanism 74 drives the outer conveying belt 70 to swing left in a fan-shaped trajectory with the rotary support as the center and the vertical long edge of the outer conveying belt 70 as the diameter, until the horizontal swing mechanism 74 swings 135°;
[0082] Step two, outer conveying belt 70 single feeding: the material falls into the outer conveying belt 70 through the feed port 77, and with the operation of the outer pulley on the mobile telescopic device 7, the material rises along the outer conveying belt 70 to above the discharge port 78 and falls to the ground;
[0083] Step three, start the horizontal swing mechanism 74 again: the horizontal swing mechanism 74 drives the outer conveying belt 70 to swing and drop in a fan-shaped trajectory with the rotary support as the center and the vertical long edge of the outer conveying belt 70 as the diameter, until the horizontal swing mechanism 74 swings 135° to the right;
[0084] Step four, start the inner conveying belt 700: extend the inner conveying belt 700 by 3m by starting the radial telescopic mechanism 7, and at the same time start the inner conveying belt 700, and after the material falls into the inner conveying belt 700 through the discharge port 78, it is conveyed along the inner conveying belt 700 to the end of the inner conveying belt 700 and then falls;
[0085] Step five, start the horizontal swing mechanism 74 again: the horizontal swing mechanism 74 swings left, with the rotary support as the center and the vertical long edge of the outer conveying belt 70 plus 3m, i.e. with the length of 16m as the diameter, to swing and drop in a fan-shaped trajectory, until the horizontal swing mechanism 74 swings 135° to the left;
[0086] Step six, start the radial telescopic mechanism 7 again: extend the inner conveying belt 700 by a specified length of 6m;
[0087] Step seven, repeat steps five and six accordingly, until the inner conveying belt 700 is fully extended by the radial telescopic mechanism 7, a total of 12m, and the horizontal swing mechanism 74 finally swings to 135° to the right, and the falling track is a continuous radial falling in a 270° fan ring surface;
[0088] The radial stacking method of the displacement conveying and stacking system can uniformly disperse the material with high humidity, such as the concentrate powder with moisture content of 30% or more, on the entire fan-shaped annular working surface, and there is a spacing of 3m between the material falling tracks, which does not affect the ventilation effect and can accelerate the drying speed. After the first layer is dried, the material continues to fall in the reverse track, which can increase the unloading amount of the working surface while drying.
[0089] Embodiment 10
[0090] The basic structure of the displacement conveying and stacking method of the continuous mining conveying system is the same as that of Embodiment 9, and the difference and improvement are as follows: Figure 3 As shown in the figure, the horizontal swing mechanism 74 swings left and right at an angle of 45°, which can form a 90° fan-shaped annular working surface, and is suitable for unloading and drying in a small area. The lengths of the inner conveying belt 700 and the outer conveying belt 70 are 15m and 16m respectively, and the widths are both 1.2m. The inner conveying belt 700 is extended by 5m each time by the radial telescopic mechanism 7, including the following steps:
[0091] Step one, start the horizontal swing mechanism 74: the horizontal swing mechanism 74 drives the outer conveying belt 70 to swing left in a fan-shaped trajectory with the rotary support as the center and the vertical long side of the outer conveying belt 70 as the diameter, until the horizontal swing mechanism 74 swings 45°;
[0092] Step two, outer conveying belt 70 single feeding: the material falls into the outer conveying belt 70 through the feeding port 77, and rises along the outer conveying belt 70 to the above of the material falling port 78 and falls to the ground along with the rotation of the outer pulley on the moving telescopic device 7;
[0093] Step three, start the horizontal swing mechanism 74 again: the horizontal swing mechanism 74 drives the outer conveying belt 70 to swing and fall in a fan-shaped trajectory with the rotary support as the center and the vertical long side of the outer conveying belt 70 as the diameter, until the horizontal swing mechanism 74 swings 45° to the right;
[0094] Step four, start the inner conveying belt 700: extend the inner conveying belt 700 by 5m by starting the radial telescopic mechanism 7, and at the same time start the inner conveying belt 700. The material falls into the inner conveying belt 700 through the material falling port 78, and is conveyed along the inner conveying belt 700 to the end of the inner conveying belt 700 and then falls;
[0095] Step five, start the horizontal swing mechanism 74 again: the horizontal swing mechanism 74 swings left with the rotary support as the center and the vertical long side of the outer conveying belt 70 plus 5m, i.e. the length of 21m as the diameter, to swing and fall in a fan-shaped trajectory, until the horizontal swing mechanism 74 swings 45° to the left;
[0096] Step six, radial telescopic mechanism 7 restart: extend inner conveyor belt 700 by a specified length of 10m;
[0097] Step seven, repeat step five and six in this way until radial telescopic mechanism 7 extends inner conveyor belt 700 by a total of 15m, horizontal swing mechanism 74 swings to the right by 45° in the end, and the blanking rail is a continuous radial blanking of 90° sector surface;
[0098] Step eight, caterpillar moving mechanism II 76 starts: pause feeding, caterpillar moving mechanism II 76 drives the entire device to shift to the next blanking surface;
[0099] Step nine, reverse blanking: feeding restarts, blanking along the reverse track of the continuous radial blanking rail in step seven.
