DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, please refer to the attached drawings, the present invention provides a technical solution: An ore transport device for underground iron mines comprises a base 100, and vertical side plates 101 are symmetrically fixed on both sides of the top surface of the base 100; like Figure 1 As shown, a first transport mechanism is provided between the upper parts of the two side plates 101, a second transport mechanism is provided between the lower parts, a loading assembly is provided between one ends of the two side plates 101, and a unloading assembly is provided between the other ends; The first transport mechanism includes a rotating switching assembly, and two rotating switching assemblies are provided on the inner side surface of each side plate 101, wherein one rotating switching assembly is close to the unloading assembly, and the other rotating switching assembly is close to the loading assembly. A horizontal lower guide plate 603 is fixed on the inner side surface of the side plate 101 at a position corresponding to the position between the lower parts of the two rotating switching assemblies, and a horizontal upper guide plate 604 is fixed at a position corresponding to the position between the upper parts of the two rotating switching assemblies. A plurality of material storage and transport assemblies are provided on the two lower guide plates 603, and a plurality of material storage and transport assemblies are also provided on the two upper guide plates 604. A feeding assembly is provided on the upper guide plate 604, and a return assembly is provided on the lower guide plate 603. A driving assembly is connected between the feeding assembly and the return assembly on the same side plate 101; The second conveying mechanism includes two parallel conveying wheels 108 rotatably connected between the lower parts of the two side plates 101, and a conveying belt 109 is provided on the two conveying wheels 108. One end of one of the conveying wheels 108 is connected to a motor, and the conveying wheel 108 and the conveying belt 109 are driven by the motor to move, so as to convey the ore material screened in the first transport mechanism and convey it to the second unloading trough 103 for unloading; like Figure 6 As shown, the material storage and transportation component includes a material storage trough 300, a screening structure is provided at the lower portion of the inner cavity of the material storage trough 300, horizontal sliding plates 303 are symmetrically fixed on both sides of the material storage trough 300, the bottoms of the two sliding plates 303 are respectively slidably connected to the top surfaces of the lower guide plates 603 or the upper guide plates 604 on both sides, a telescopic structure is provided at the top of the sliding plate 303, and the telescopic structure is correspondingly connected to the rotating switching component.

[0024] When transporting ore, the ore is moved to the storage trough 300 located at the top of the lower guide plate 603 and close to the loading assembly through the loading assembly, and the multiple storage troughs 300 on the lower guide plate 603 are intermittently moved toward the lower feeding assembly through the feeding assembly. During the movement, the ore is screened by the screening structure in the storage trough 300, so that smaller ores fall into the second transportation mechanism for transportation, and larger ores remain in the storage trough 300 and are transported by the first transportation mechanism, so as to avoid all the ores being pressed on the conveying structure such as the conveyor belt 109, reduce the pressure of the single conveying structure, reduce the impact on the conveying structure, and improve the conveying stability.

[0025] When the first transport mechanism and the second transport mechanism drive the corresponding ore to move to the unloading assembly, the unloading assembly unloads the ore in the first transport mechanism and the second transport mechanism respectively, thereby completing the ore transportation.

[0026] When the storage trough 300 moves to the rotating switching component at the unloading end of the device, the telescopic structures on both sides of the storage trough 300 are connected to the corresponding rotating switching components. After the storage trough 300 unloads the ore therein, the storage trough 300 is moved from the height position of the lower guide plate 603 to the height position of the upper guide plate 604 through the rotation of the rotating switching component, and the telescopic structure automatically adapts to the distance change of the rotating switching components on both sides during the rotation process to ensure that the position of the storage trough 300 is switched smoothly.

[0027] When the storage trough 300 moves to the height position of the upper guide plate 604, the return component is used to intermittently move the storage trough 300 toward the lower material component, so that the empty storage trough 300 can return to its position, and when returning to the lower material component, the switching component at the corresponding position is used to enable the storage trough 300 to return from the height position of the upper guide plate 604 to the height position of the lower guide plate 603, and continue to load and transport.

[0028] Among them, Figure 4 As shown, the rotation switching assembly includes a fixed end plate 600 vertically fixed on the inner side of the side plate 101, a rotating frame 601 is rotatably connected to the middle of the inner side of the fixed end plate 600, a motor is connected to the center of the rotating frame 601, and horizontal switching shafts 602 are fixed to the upper and lower sides of the rotating frame 601, and are correspondingly connected to the telescopic structure through the switching shaft 602, a rotating groove 104 is provided on the side plate 101 at a position corresponding to the rotating frame 601 and the switching shaft 602, and the two ends of the lower guide plate 603 are fixedly connected to the fixed end plates 600 on both sides, and the two ends of the upper guide plate 604 are respectively located at the corresponding sides of the rotating groove 104.

[0029] When the material storage trough 300 on the lower guide plate 603 moves to the unloading position of the device, the switching shaft 602 extends into the telescopic structure on the material storage trough 300, and after the material storage trough 300 completes unloading, the motor drives the rotating frame 601 and the switching shaft 602 to rotate, and the switching shaft 602 at the lower position rotates inward and upward, thereby driving the telescopic structure and the material storage trough 300 to move, so that the material storage trough 300 moves from the height position of the lower guide plate 603 to the position of the upper guide plate 604, and during the movement, the distance between the switching shafts 602 on both sides of the material storage trough 300 will change, and the telescopic structure will automatically adapt to the position change of the switching shaft 602 to ensure that the position of the material storage trough 300 can be switched smoothly.

[0030] Among them, Figure 7As shown, the telescopic structure includes a telescopic block 304 slidably connected to the top surface of the sliding plate 303, and a limit hole 305 is provided on the telescopic block 304, and the limit hole 305 is correspondingly linked to the switching shaft 602, and a telescopic shaft 307 is fixed to the inner end of the telescopic block 304, one end of the telescopic shaft 307 passes through the side wall of the storage trough 300, and is fixed with a telescopic plate 309, and a spring end plate 308 is fixed on the telescopic shaft 307, a spring is connected between one side of the spring end plate 308 and the outer side wall of the storage trough 300, and a pushing wheel 306 is rotatably connected to the other side of the telescopic shaft 307 corresponding to the spring end plate 308, and the pushing wheel 306 is correspondingly connected to the feeding assembly and the return assembly.

[0031] When the material storage trough 300 moves to the rotating switching assembly, the switching shaft 602 is located inside the limiting hole 305. When the rotating frame 601 drives the switching shaft 602 to rotate, the switching shaft 602 drives the telescopic block 304 to move in the direction of the material storage trough 300, and the telescopic shaft 307 and the telescopic plate 309 slide toward the inner cavity of the material storage trough 300, and the spring end plate 308 compresses the spring. Then, when the switching shaft 602 drives the material storage trough 300 to move to the height position of the upper guide plate 604, the telescopic block 304 moves outward with the switching shaft 602, thereby automatically adjusting the position, realizing the horizontal distance change of the switching shaft 602 on both sides of the material storage trough 300 during the rotation process, so that the height position of the material storage trough 300 can be smoothly switched.

[0032] Wherein, the feeding assembly includes a feeding push plate 401, the position of the feeding push plate 401 is staggered with the position of the lower guide plate 603, and corresponds to the position of the pushing wheel 306, a plurality of pushing grooves 402 are evenly arranged at the bottom of the feeding push plate 401, some of the pushing grooves 402 are correspondingly connected to the pushing wheel 306, and a plurality of parallel rotating short rods 403 are evenly arranged on the side of the feeding push plate 401 close to the side plate 101, a short shaft 404 is fixed to one end of the rotating short rod 403, and the rotating short rod 403 is rotatably connected to the upper part of the feeding push plate 401 through the short shaft 404, a rotating shaft 405 is fixed to the other end of the rotating short rod 403, the rotating shaft 405 is rotatably connected to the side plate 101, and one end extends out of the side plate 101 and is correspondingly connected to the driving assembly; The return assembly includes a return push plate 400, which has the same structure as the feed push plate 401, and is connected with a short shaft 404, a rotating short rod 403 and a rotating shaft 405 of the same structure, and one end of the rotating shaft 405 of the return assembly is also connected to the driving assembly accordingly.

[0033] When the driving assembly is working, the rotating shaft 405 and the rotating short rod 403 of the feeding assembly and the return assembly are driven to rotate respectively, and the feeding push plate 401 and the return push plate 400 reciprocate with the circular motion of the rotating short rod 403 while maintaining a horizontal position; Among them, under the action of the circular motion of the corresponding rotating short rod 403, the feeding push plate 401 first moves to the feeding side of the device, and the height position gradually decreases. When the pushing groove 402 on the feeding push plate 401 is located at the pushing wheel 306, the rotating short rod 403 drives the feeding push plate 401 to move to the lower material side, and drives the pushing wheel 306 and the storage tank 300 and other structures to move to the front side, so as to realize the movement of multiple storage tanks 300 on the lower guide plate 603; Then the feeding push plate 401 continues to move toward the upper material side with the movement of the rotating short rod 403, and the height position gradually increases, and the feeding push plate 401 is disengaged from the push wheel 306 and stops moving when the rotating short rod 403 is in a vertical state, so that the storage trough 300 and other structures can move from the height position of the lower guide plate 603 to the height position of the upper guide plate 604 through the action of the rotating switching component.

[0034] When the feeding push plate 401 moves, the return push plate 400 moves synchronously and in the opposite direction. Thus, through the same working principle, the multiple storage troughs 300 move from the unloading side to the loading side of the device, completing the return of the multiple storage troughs 300.

[0035] The uniform rotation of the rotating short rod 403 is converted into a variable speed linear motion of the storage tank 300 through the transmission of the feeding push plate 401. The variable speed motion causes a certain shaking of the ore in the storage tank 300, thereby improving the screening effect.

[0036] Among them, Figure 5 As shown, the driving assembly includes two support seats 501 fixed on the outer surface of the side plate 101, a worm 500 is rotatably connected to the two support seats 501, and one end of the worm 500 is connected to a motor, a first gear 406 is fixed to the end of the rotating shaft 405, a second gear 503 is meshed on the first gear 406, a worm wheel 502 is coaxially fixed on the second gear 503, and the second gear 503 and the worm wheel 502 are rotatably connected to the side plate 101, and the worm wheels 502 in the return assembly and the feeding assembly are respectively located on the upper and lower sides of the worm 500 and meshed with the worm 500.

[0037] When the feeding assembly and the return assembly are working, the worm 500 is driven by the motor to rotate, and through the transmission of the worm wheel 502, the first gear 406 and the second gear 503, all the rotating shafts 405 drive the corresponding rotating short rods 403 to rotate, so that the feeding push plate 401 and the return push plate 400 are rotated in different directions respectively, and the motor and the worm 500 and other structures move intermittently, and the rotating short rod 403 pauses after each rotation of one circle, so that the rotating switching assembly can work and switch the upper and lower positions of the storage trough 300, and then the driving assembly works again to continue moving the positions of multiple storage troughs 300.

[0038] Embodiment 2: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 8 As shown, the screening structure includes a rotating screen 302 located in the storage trough 300, one end of the rotating screen 302 is rotatably connected to the inner wall of the storage trough 300, and inclined second hydraulic telescopic rods 310 are symmetrically arranged and rotatably connected on both sides of the bottom of the rotating screen 302, and the other end of the second hydraulic telescopic rod 310 is rotatably connected to the bottom of the inner wall of the storage trough 300, and limiting platforms 301 are fixed on the four inner cavity side walls of the storage trough 300, and the top surface of the limiting platform 301 is inclined, and the bottom surface contacts the top surface of the rotating screen 302.

[0039] After the ore material is loaded in the storage trough 300, the ore is located on the rotating screen 302, and the rotating screen 302 is limited by the limit platform 301 and the second hydraulic telescopic rod 310, and then the storage trough 300 is intermittently moved through the intermittent movement of the feeding assembly. Each time it moves, a certain shaking effect is generated on the ore material, so that the ore is screened by the rotating screen 302, so that smaller ores can pass the screening and fall onto the second transportation mechanism, and larger ores remain in the storage trough 300 and are transported by the first transportation mechanism, thereby realizing the screening of ore materials and separately transporting ore materials of different sizes.

[0040] Embodiment 3: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 3 As shown, the loading assembly includes a loading box 200 fixed between the tops of the two side plates 101, as shown in FIG. Fig.10 As shown, an inclined fixed material pipe 203 is fixed to the bottom of the upper material box 200, and the bottom of the upper material box 200 is inclined toward the fixed material pipe 203. A movable material pipe 205 is provided on the fixed material pipe 203, and the end of the movable material pipe 205 is connected to the bottom of the fixed material pipe 203 through a first hydraulic telescopic rod 204; like Fig.11 As shown, the end of the fixed material tube 203 extends into the interior of the movable material tube 205, and the top surface is slidably connected to the top surface of the inner cavity of the movable material tube 205, the bottom of the inner cavity of the movable material tube 205 is rotatably connected to the limiting wheel 206, and the limiting wheel 206 contacts the bottom surface of the fixed material tube 203, and a limiting seat 207 is fixed to the top of the inner cavity of the movable material tube 205. The side of the limiting seat 207 close to the fixed material tube 203 is connected to a sealing plate 208 through a spring, and two parallel guide shafts 209 are fixed to the other side of the sealing plate 208. The guide shafts 209 pass through the limiting seat 207 and are slidably connected to the limiting seat 207.

[0041] When feeding through the feeding box 200, the movable material pipe 205 moves outward, so that the sealing plate 208 is separated from the end of the fixed material pipe 203, and the outer end of the movable material pipe 205 is located above the material storage tank 300 on the first guide plate, so that the ore entering the feeding box 200 can move along the fixed material pipe 203 and be discharged through the movable material pipe 205. When the ore is discharged from the fixed material pipe 203 to the movable material pipe 205, it may contact the sealing plate 208. The sealing plate 208 can be moved by the action of the spring and the guide shaft 209, thereby providing a buffering effect and reducing damage to the sealing plate 208. When the material storage trough 300 close to the loading assembly switches its position from top to bottom, the movable material pipe 205 is moved toward the fixed material pipe 203 by the first hydraulic telescopic rod 204, so that the sealing plate 208 contacts the end of the fixed material pipe 203, so that the fixed material pipe 203 is closed and the discharge of materials is suspended. At the same time, the end of the movable material pipe 205 is staggered with the position of the material storage trough 300 to avoid the position switching of the material storage trough 300.

[0042] like Figure 2 As shown, the material unloading assembly includes a first unloading chute 102 and a second unloading chute 103 located below the first unloading chute 102, the inner side end of the first unloading chute 102 is located below the lower guide plate 603 and the material storage trough 300, and the inner side end of the second unloading chute 103 is located below the second conveying mechanism, so as to unload the materials in the first conveying mechanism and the second conveying mechanism respectively, and the outer side section of the first unloading chute 102 is bent to one side, and the outer side section of the second unloading chute 103 is bent to the other side, so that the first unloading chute 102 is bent to the other side, so that the first unloading chute 102 is bent to the second conveying mechanism. The material dropping positions of the first material dropping chute 102 and the second material dropping chute 103 are staggered, and a vertical fixing column 105 is fixed on the base 100, and a first support frame 106 and a second support frame 107 are fixed on the fixing column 105 respectively, and the first support frame 106 is fixed between the first material dropping chute 102 and the base 100, and the second support frame 107 is fixed between the second material dropping chute 103 and the base 100, so as to provide support for the first material dropping chute 102 and the second material dropping chute 103 and improve the position stability.

[0043] Embodiment 4: The structure of this embodiment is basically the same as that of embodiment 3, except that Fig.10 As shown, a collecting hopper 201 is fixed to the upper part of the inner cavity of the feeding box 200, and a crushing assembly is provided below the collecting hopper 201. The crushing assembly includes two symmetrical and parallel crushing wheels 202. Both ends of the crushing wheels 202 are rotatably connected to the side walls of the feeding box 200, and a crushing gear is fixed to one end. The two crushing gears are meshed with each other, and one of the crushing gears is connected to a motor.

[0044] When the ore enters the loading box 200, the ore is concentrated on the crushing wheel 202 through the collecting hopper 201. The two crushing wheels 202 are driven by the motor and the two crushing gears to rotate, and then the ore is crushed by the crushing wheel 202 to avoid the ore being too large and affecting the subsequent transportation and transfer.

[0045] Embodiment 5: The structure of this embodiment is basically the same as that of embodiment 1, except that Fig. 9 As shown, a plurality of spring grooves 605 are evenly arranged along the circumferential direction on the switching shaft 602, and a friction block 606 is slidably connected in the spring groove 605, and the inner end of the friction block 606 is connected to the inner end of the spring groove 605 through a plurality of evenly arranged springs. When the telescopic block 304 moves onto the switching shaft 602, the friction block 606 is restricted by the inner wall of the limiting hole 305 and retracts. At the same time, through the action of the spring, it maintains contact with the inner wall of the limiting hole 305 and increases the friction force, thereby avoiding accidental displacement of the telescopic block 304 and the storage trough 300 when the rotating switching component moves.
