[0025] In a specific solution, the sliding trough frame 240 is located in the starting position inside the carrier frame 23, and the hydraulic telescopic rod 241 is in a retracted state. Secondly, the transverse rail frame 242 and the longitudinal rail frame 243 are located in the initial position, and the positioning guide drive structure 244 and the guide rod 245 are also in the initial position. Then, when the ore material reaches the surface of the screening grid frame 3 and is screened and discharged by driving the multi-stage transmission arm structure 2, when the screening grid frame 3 is blocked, the hydraulic telescopic rod 241 extends to push the sliding trough frame 240 to slide along the inside of the carrier frame 23, so that it moves to the blocking position.

[0026] In the present invention, according to Figure 1 - Figure 3 As shown, the top of the slope bearing frame 5 is rotatably connected with an adjusting rotating rod 8, and the adjusting rotating rod 8 is rotatably connected to the left top end of the discharge screen 9. A material baffle plate is installed on the side end of the discharge inclined plate 15, which is used to prevent the material from being scattered due to a large impact when the material is output to the surface of the discharge screen 9.

[0027] An arc groove conveying baffle 7 is installed inside the top of the conveyor belt structure 6, and the bottom end of the conveyor belt structure 6 is connected to an output limiting groove frame 16. The output end of the output limiting groove frame 16 and the surface of the screening grid 3 form a vertical axis.

[0028] The top of the support frame 23 is fastened with a large discharge tray 17 , the corners of the large discharge tray 17 are equipped with a force unloading elastic spring 20 , the side ends of the force unloading elastic spring 20 are equipped with a force unloading arc plate 18 , and the side ends of the large discharge tray 17 are equipped with a discharge belt structure 19 .

[0029] In a specific scheme, when the above-mentioned crushed ore is transported to the conveyor belt structure 6 through the slope bearing frame 5, the arc groove conveying baffle 7 installed inside the top of the conveyor belt structure 6 is used to prevent the ore from scattering during transportation, and by adjusting the rotating rod 8, when the two groups of vibrating lifting rods 10 vibrate the discharge screen 9 to further screen the ore, the discharge screen 9 can be adjusted up and down, and the angle of the discharge screen 9 can be adjusted to ensure that the ore is evenly distributed on the discharge screen 9, thereby improving the screening effect. The large-particle ore discharged from the discharge screen 9 will enter the large discharge plate 17 and roll along the slope of the large discharge plate 17. The unloading elastic spring 20 installed at the corner is used to drive the unloading arc plate 18 to buffer the impact force of the ore when the large-particle ore rolls, and forces the large-particle ore to turn to the discharge belt structure 19 for transportation during the rolling process, thereby effectively reducing the wear of the equipment.

[0030] In the present invention, according to Figure 1 - Figure 4 and Figure 5 As shown, a driving multi-stage transmission arm structure 2 is installed inside the support frame 1, and the driving multi-stage transmission arm structure 2 is composed of a driving motor, a pulley structure, a speed regulator, a multi-stage transmission rod and a connecting block. The connecting block is fastened to the side end bottom wall surface of the screening grid 3.

[0031] A crusher drive structure 13 is installed on the top of the top fixing frame 11, and a crushing structure 22 is installed inside the crusher body 12. The output end of the crusher drive structure 13 and the crushing structure 22 are connected. A plurality of groups of external spray heads are evenly installed on the surface of the top fixing frame 11 and the support frame 1. The pipelines of the plurality of groups of external spray heads and the rotary sprayer 219 are connected through an adapter pressurized conveyor and an external water pump tank.

[0032] Photoelectric sensors are installed on the sides of the discharge screen 9 and the screening grid frame 3, and one end of the screening grid frame 3 is rotatably connected to a discharge plate 26.

[0033] The other end of the screening grid 3 is fastened with a solid block, and a pneumatic lifting rod 27 is installed on the side end of the solid block. The pneumatic lifting rod 27 is installed on the surface of the supporting frame 1, and a slot frame 25 is installed on the side of the screening grid 3.

[0034] In a specific scheme, after the mined ore enters the crusher body 12 with the cooperation of the external buffer conveyor belt, the crushing structure 22 is driven by the crusher drive structure 13 to crush the ore into smaller particles, and the shock-absorbing structure 14 reduces the vibration during the crushing process. Photoelectric sensors are installed on the side ends of the discharge screen 9 and the screening grid 3 to detect the flow of the ore to ensure the screening effect. The pneumatic lifting rod 27 is used to lift the ore particles that have not entered the surface of the screening grid 3 after screening by the screening grid 3 through the rotatably connected discharge plate 26, and slide and roll to the external conveying structure on the other side. During the screening operation, the design of the external spray head and the rotary sprayer 219 can effectively reduce dust and temperature drop, thereby improving the safety and comfort of the working environment.

[0035] The wiring diagrams of the photoelectric sensor, the driving multi-stage transmission arm structure 2, the crusher driving structure 13 and the pneumatic lifting rod 27 in the present invention are common knowledge in the field, and their working principles are already known technologies. The models are selected according to actual use, so the control method and wiring layout of the photoelectric sensor, the driving multi-stage transmission arm structure 2, the crusher driving structure 13 and the pneumatic lifting rod 27 are no longer explained in detail.

[0036] The method of use and working principle of this device: First, when the mined ore enters the crusher body 12 with the cooperation of the external buffer conveyor belt, the crushing structure 22 is driven by the crusher driving structure 13 to crush the ore into smaller particles, and the shock-absorbing structure 14 reduces the vibration during the crushing process, so that the crushed ore is evenly distributed on the discharge screen 9 through the discharge inclined plate 15. The discharge screen 9 has a large diameter, and under the operation of two sets of vibrating lifting rods 10, it can drive the discharge screen 9 to oscillate up and down, so that the small crushed materials produced can fall from the large diameter to the conveyor belt structure 6 for continued transportation, while the large particles that cannot fall will roll from the inclined discharge screen 9, and the adjusting rotating rod 8 can make the two sets of vibrating lifting rods 10 vibrate the discharge screen 9 to further screen. When the ore is crushed, the discharging screen 9 can be adjusted up and down, and the angle of the discharging screen 9 can be adjusted to ensure that the ore is evenly distributed on the discharging screen 9, thereby improving the screening effect. The large particles of ore discharged from the discharging screen 9 will enter the large discharging plate 17 and roll along the slope of the large discharging plate 17. The unloading elastic spring 20 installed at the corner is used to drive the unloading arc plate 18 to buffer the impact force of the ore when the large particles of ore roll, and force the large particles of ore to turn to the discharge belt structure 19 for transportation during the rolling process, thereby effectively reducing the wear of the equipment. When the above-mentioned crushed ore is transported to the conveyor belt structure 6 through the slope bearing frame 5, the arc groove conveying baffle 7 installed inside the top of the conveyor belt structure 6 is used to prevent the ore from being crushed during transportation. The output limit slot frame 16 is convenient for blocking the ore materials after screening when the conveyor belt structure 6 transports the ore materials, so that the ore materials fall into the screening grid frame 3. Then the multi-stage transmission arm structure 2 is started to drive the multi-stage transmission arm structure 2 to drive the screening grid frame 3 to slide and connect to the top side of the support frame 1 through the moving wheel 4 for further screening. After screening, the remaining ore materials that cannot fall down are lifted by the pneumatic lifting rod 27 through the rotatably connected discharge plate 26 to lift the ore particles that have not entered the surface of the screening grid frame 3, and slide and roll to the external conveying structure on the other side. At the same time, during the screening operation, the design of the external spray head and the rotary sprayer 219 can effectively reduce dust and temperature drop, thereby improving the safety of the working environment. And comfort, then, when the screening grid frame 3 is blocked, the hydraulic telescopic rod 241 extends, pushing the sliding slot frame 240 to slide along the inside of the carrier frame 23, so that it moves to the top of the blocked position, and then after the sliding slot frame 240 reaches the specified position, the positioning guide driving structure 244 is started to drive the longitudinal rail frame 243 to move vertically downward along the transverse rail frame 242, and the movement of the longitudinal rail frame 243 is precisely controlled by the motor and the transmission mechanism to ensure that the guide rod 245 reaches the blocked position. After the guide rod 245 reaches the blocked position, it is driven by the positioning guide driving structure 244 to move up and down and left and right accurately, directly contact and clean the blockage, without the need for manual intervention as a whole, thereby improving production efficiency and safety, and ensuring that the blockage is fully cleaned.To improve the cleaning effect, the ore after the above-mentioned multi-operation screening operation enters the injection end 212 through the left chute plate 210 and the right chute plate 211, and enters the particle size guide wheel 213 from the injection end 212, which rotates and pushes the particles in the injection end 212 for preliminary classification and guidance according to the particle size. The ore enters the discharge cavity between the outer shell 214 and the inner shell 215, and is finely screened through four groups of spiral channels 216 and spiral screening channels 217. The screening diameter is from large to small, ensuring that ores of different particle sizes are effectively separated. During fine screening, the dust and mist particles generated escape from the spiral screening channel 217 to Inside the inner shell 215, the rotating frame 218 then drives the rotary sprayer 219 to rotate, forming a guided airflow inside the inner shell 215 to attract the scattered dust and mist particles, and the rotary sprayer 219 sprays liquid mist to gather the generated dust and mist particles. After that, the screened ore is discharged through the bottom of the spiral screening channel 217, and enters different collection devices according to the ores of different particle sizes, and the gathered dust and mist particles are discharged from the opening and closing discharge chute 2190, so that when large-scale batch conveying and screening operations are carried out, multi-level screening can be carried out, and ores of different particle sizes can be accurately distinguished, thereby improving the screening effect and efficiency.
