DETAILED DESCRIPTION

[0019] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. Example

[0020] A fast discharge device for horizontal shafts and tunnels, wherein a working pit 02 is opened at a position directly below the vertical shaft 01 in the horizontal shaft and tunnel 00. Figure 1 As shown, the discharging device comprises a slope slide 1 and a hoisting mechanism 2; the slope slide 1 is arranged in an inclined manner, the upper part of which is not higher than the elevation of the horizontal shaft 00, and the lower part of which extends into the working pit 02; The lifting mechanism 2 includes a lifting rope 21 and a discharge bucket 22 connected to the lifting rope 21. When in use, the discharge bucket 22 is lowered into the working pit. After the stone is loaded onto the slope slide 1, it can slide directly into the discharge bucket 22 along the slope slide 1, eliminating the secondary loading process of the excavator in the prior art, making the entire loading process lower in energy consumption, lower in cost, and higher in efficiency.

[0021] See also Figure 2 As shown, the inclined slide 1 has an inclined chute 11 , which effectively restricts the stones from sliding on the inclined slide 1 .

[0022] Since it is difficult to accurately control the amount of stone entering the discharge barrel 22, stones often overflow from the discharge barrel 22. After the stones overflow, they will be arranged around the discharge barrel 22. When the discharge barrel 22 transports the stones out of the tunnel and resets them to their original position, the discharge barrel 22 is difficult to place stably because of the presence of previously overflowed stones at the position where the discharge barrel 22 needs to be reset. Therefore, it often needs to be cleaned, affecting the efficiency of stone delivery.

[0023] To this end, the discharging device in the embodiment further comprises an overflow isolation platform 3 arranged at the tail end of the ramp slide 1, such as Figure 3-4As shown, the overflow isolation platform 3 includes an insertion groove 31 for accommodating the discharge barrel 22, and an overflow slope 32 is arranged on the overflow isolation platform 3 near the slot of the insertion groove 31. When stones enter the discharge barrel 22, excess stones can roll down the overflow slope 32 to the outside of the overflow isolation platform 3, and the overflow isolation platform 3 separates the overflowed stones from the discharge barrel 22 in the insertion groove 31. Therefore, when the discharge barrel 22 transports the stones out of the tunnel and resets them to the insertion groove 31, it is no longer affected by the previously overflowed stones, and there is no unstable placement phenomenon. The stone delivery efficiency can be guaranteed. In addition, the insertion groove 31 on the overflow isolation platform 3 effectively restricts the discharge barrel 22 to prevent the discharge barrel 22 from being impacted by the stones and tipping over. A retaining ring 23 is provided at the edge of the barrel mouth of the discharge barrel 22. The retaining ring 23 is coaxially arranged with the discharge barrel 22 and surrounds the edge of the barrel mouth. When the discharge barrel 22 is placed in the insertion groove 31, the retaining ring 23 covers the overflow slope 32 to prevent the stones sliding down the slope slide 1 from sliding into the insertion groove 31.

[0024] Generally speaking, the overflowed stones need to be reloaded into the discharge barrel 22 manually or with the help of mechanical equipment, which results in additional manual workload.

[0025] To this end, a material return structure 4 is also included, which includes a material return table 41. The material return table 41 includes a collecting trough 411. A through hole 412 is provided at the bottom center of the collecting trough 411. The overflow isolation table 3 passes through the through hole 412, and the stones overflowing from the discharge barrel 22 are confined in the collecting trough 411.

[0026] The return material structure 4 also includes a lifting drive mechanism for lifting the return material platform 41, the lifting drive mechanism includes a lifting rod 421 connected to the return material platform 41 and provided with a magnet 422, a rod mounting platform 423 for slidingly mounting the lifting rod 421, a coil circuit with a coil portion 424, a mounting column 425 for fixing the coil portion 424, a toggle switch 426 arranged in the coil circuit, and a trigger mechanism for turning on the toggle switch 426, the coil portion 424 is directly opposite to the magnet 422, the trigger mechanism includes a trigger rod 427, the trigger rod 427 passes through the overflow isolation platform 3 and extends into the insertion groove 31, the trigger rod 427 is connected to a reset spring 428 connected to the overflow isolation platform 3, the trigger rod 427 is connected to the toggle switch 426, and when the discharge barrel 2 When the trigger rod 427 is pressed, the trigger rod 427 overcomes the elastic force of the return spring 428 and moves downward. When the trigger rod 427 moves downward, it toggles the toggle switch 426 to turn on the toggle switch 426. When the toggle switch 426 is turned on, the coil circuit is energized to generate a magnetic field opposite to the magnet 422, so that the lifting rod 421 moves upward to achieve the lifting of the return platform 41. When the return platform 41 is lifted, the stones accumulated inside it can be returned to the discharge barrel 22. Compared with the traditional manual or mechanical equipment to return the overflowed stones to the discharge barrel 22, no additional manual work is required. When the discharge barrel 22 leaves the insertion slot 31, the trigger rod 427 is reset under the action of the spring, driving the toggle switch 426 to reset, the coil circuit is de-energized, and the return platform 41 is reset.

[0027] In the embodiment, there are multiple coil parts 424 arranged in a circle, and accordingly, there are also multiple lifting rods 421. The magnetic fields generated by the multiple coil parts 424 interact with the magnets to provide a greater lifting force.

[0028] A pressure block 4211 is provided at the part of the lifting rod 421 located above the rod mounting platform 423. When the coil circuit is powered off, the lifting rod 421 is pressed on the rod mounting platform 423 by the pressure block 4211, so that the lifting rod 421 does not directly contact the mounting column 425, thereby reducing the force on the mounting column 425. A limit block 4212 is provided at the part of the lifting rod 421 located below the rod mounting platform 423, which effectively limits it on the rod mounting platform 423 and also limits the lifting distance of the lifting rod 421.

[0029] The bottom of the collecting trough 411 is inclined upward as it moves away from the through hole 412 . After the return platform 41 is lifted, the stones can more easily return to the discharge barrel 22 due to the effect of the inclined surface.

[0030] A buffer component 5 is provided above the discharge barrel 22. The buffer component 5 can be a pendulum ball, which is suspended and connected to the suspension rope 21. When the stone slides down the slope slide 1, the speed of the stone is reduced. On the one hand, it prevents the stone from flying over the discharge barrel 22, so that the stone can smoothly enter the discharge barrel 22. On the other hand, it can also reduce the impact of the stone on the barrel wall of the discharge barrel 22.

[0031] A cover is provided on the slope chute 11 to prevent stones from escaping out of the slope chute 11 when sliding on the slope chute 11. The cover is not shown in the drawings.

[0032] like Figure 5 As shown, the upper end of the slope slide 1 is connected to a horizontal feeding section 6, and the horizontal feeding section 6 has a horizontal feeding trough 61 connected to the entrance of the slope chute 11. The mined stones can be poured into the horizontal feeding trough 61 first. When a certain amount of loading is achieved, the pushing plate can be used to push the stones into the slope chute 11.
