[0025] like Figure 1-3 As shown, an automated pulping station suitable for the cross-section of underground mine roadways includes a guide rail 2, a pulping machine 8, and a mixer 12. The guide rail 2 is laid along the roof of the roadway 1 and can be an I-beam. It is anchored to the roof of the roadway 1 by anchor bolts. The guide rail 2 extends along the extension direction of the roadway 1. A drive vehicle 3 is slidably mounted on the guide rail 2. The drive vehicle 3 is driven by a stepper motor and is equipped with an electric hoist (the drive vehicle 3 can refer to the structure of a traveling crane). One end of the guide rail 2 extends to the storage station, and the other end extends to the mixing station, so that the ton bag 4 can be hoisted and moved between the storage station and the mixing station. The pulping machine 8 is located at the mixing station, and the feed inlet of the pulping machine 8 is connected to a screw conveyor 7. The outlet of the hopper 6 and pulper 8 is connected to the mixer 12 via the pump body 9, thereby transferring materials to the pulper 8. The feed inlet of the pulper 8 is located at the top and is also connected to a water supply pipe 11. A water supply solenoid valve is installed on the water supply pipe 11. A weighing module is installed at the bottom of the pulper 8. Materials and water are supplied sequentially. The material ratio is controlled according to the detection of the weighing module. The pulper 8 is equipped with a pulping motor, and the mixer 12 is equipped with a stirring motor. The screw feeder 7 is a screw guiding device driven by the feeding motor. The pulper 8, pump body 9, mixer 12, screw feeder 7, water supply solenoid valve and weighing module are connected to the controller to realize automated pulping.

[0026] In an optional embodiment, the hopper 6 is a conical groove, specifically a polygonal pyramid or a cone. The bottom of the hopper 6 corresponds to the feed end of the screw feeder 7 and is fixedly connected to the guide pipe of the screw feeder 7 by welding.

[0027] The screw feeder 7 includes a guide pipe and a screw guide rod. The screw guide rod is rotatably connected inside the guide pipe. One end of the screw guide rod extends out of the guide pipe and is connected to the feeding motor. The upper end of the guide pipe is provided with a discharge end, which is connected to the feed inlet of the pulper 8 through a corrugated pipe.

[0028] In one optional embodiment, the bottom of the outer frame of the pulper 8 is provided with height-adjustable support legs. These legs can be spirally connected or multi-sectioned, allowing for height adjustment as needed. Furthermore, the screw feeder 7 is hinged to the feed inlet of the pulper 8, allowing for angle changes based on height adjustment. A support mechanism is provided at one end of the screw feeder 7 corresponding to the hopper 6. This support mechanism supports the guide pipe of the screw feeder 7.

[0029] The support mechanism includes a support member 14 and a support leg 13. The support leg 13 is a triangular truss, and the support member 14 is an arc-shaped plate corresponding to the screw feeder 7. The arc-shaped plate is used to support the guide pipe of the screw feeder 7. The two support legs 13 are respectively hinged to the two ends of the support member 14 to form a hinge seat, which can be adapted to different angle changes.

[0030] Furthermore, a discharge platform 5 is provided above the hopper 6. The discharge platform 5 includes an upper platform 507, a lower platform 508, and a compression mechanism. The upper platform 507 is located above the main frame 501, and a discharge port corresponding to the outlet of the ton bag 4 is located in the middle of the upper platform 507. The bottom outlet of the ton bag 4 is generally sealed with two ropes. When using it, first untie the rope at the lower part of the outlet of the ton bag 4, and the outlet of the ton bag 4 can be passed through the discharge port. The lower platform 508 is located in the middle of the main frame 501. After the outlet of 4 passes through the discharge port, it points to the lower platform 508. The middle of the lower platform 508 is provided with a discharge pipe 503 corresponding to the discharge port. The upper end of the discharge pipe 503 is used to connect to the outlet of the ton bag 4. At this time, before the upper tie is untied, the ton bag 4 and the discharge pipe 503 can be connected without causing the material to fall. The lower end of the discharge pipe 503 points to the hopper 6. After the upper end of the discharge pipe 503 is connected to the outlet of the ton bag 4, all the tie is untied, and the material is transferred to the hopper 6 through the discharge pipe 503. The extrusion mechanism is located on the lower platform 508 and extrudes the upper end of the discharge pipe 503 circumferentially to extrude and seal the outlet of the ton bag 4 against the outer wall of the discharge pipe 503. The extrusion mechanism includes an extrusion ring 506 and an extrusion cylinder 502. The upper end of the discharge pipe 503 is a conical opening with the smaller end of the conical opening pointing upwards. The inner diameter of the extrusion ring 506 is adapted to the outer diameter of the lower part of the conical opening. The extrusion ring 506 is correspondingly sleeved on the outer wall of the conical opening of the discharge pipe 503. The extrusion ring 506 is driven by the longitudinal extrusion cylinder 502. At least two extrusion cylinders 502 are correspondingly connected to the extrusion ring 506, so that the extrusion ring 506 circumferentially squeezes the conical opening of the discharge pipe 503, thereby pressing the outlet of the ton bag 4.

[0031] Multiple corresponding unloading plates 505 are hinged on the upper platform 507 of the main frame 501. A corresponding unloading cylinder 504 is hinged below the unloading plate 505. The unloading cylinder 504 drives the unloading plate 505 to rotate upward to compress the ton bag 4 in the circumferential direction. There are 4 unloading plates 505.

[0032] The piston end of the extrusion cylinder 502 is connected to the hinge plate of the extrusion ring 506 via an extrusion spring. A vibrator is installed on the outer wall of the discharge pipe 503 to prevent blockage. A central hole corresponding to the discharge pipe 503 is provided in the middle of the lower platform 508. The inner diameter of the central hole is slightly larger than the outer diameter of the discharge pipe 503. At least four return springs are provided on the outer circumference of the discharge pipe 503. One end of the return spring is connected to the discharge pipe 503, and the other end extends radially along the discharge pipe 503 and is fixed on the lower platform 508, so that the vibration force of the vibrator can be fully released. Furthermore, a limiting platform with an outer diameter larger than the central hole is provided on the outer wall of the discharge pipe 503 to stop and limit in the longitudinal direction. Correspondingly, the extrusion cylinder 502 is hinged to the lower platform 508.

[0033] In an optional embodiment, a filter plate is provided above the hopper 6, and a vibrator is provided on the outer wall of the hopper 6. The extrusion cylinder 502, the discharge cylinder 504, the vibrator, and the solenoid valves corresponding to each cylinder are also connected to the controller, which can be a microcontroller.

[0034] In an optional embodiment, the pulper 8 has a stirring chamber, which is horizontal. A horizontally distributed stirring shaft is located inside the stirring chamber. One end of the stirring shaft extends out of the stirring chamber and connects to a pulping motor. Stirring blades are provided on the outer wall of the stirring shaft, and these blades are inclined to move the material from the inlet to the outlet 15. The bottom of the stirring chamber is an arc-shaped bottom adapted to the stirring shaft. An outlet 15 is located below the end of the stirring chamber furthest from the inlet, allowing the material to be stirred as it flows towards the outlet 15. The outlet 15 is connected to a pump body 9. The outlet end of the pump body 9 is connected to the inlet of the pulper 8 and the mixer 12 via a three-way valve 10. The three-way valve 10 switches to connect the inlet of the pulper 8 and the outlet end of the pump body 9, allowing the slurry to circulate through the pump body 9, thereby improving pulping efficiency.

[0035] The three-way valve 10 switches to connect the feed inlet of the mixer 12 with the discharge end of the pump body 9. The main body of the mixer 12 is a cylindrical barrel. Inside the mixer 12, there is a stirring shaft, which is connected to the stirring motor. The slurry is kept flowing by low-speed stirring to prevent the slurry from settling.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
