Description

Technical Field

[0001] The utility model relates to the technical field of mineral material transfer and conveying equipment, in particular to a funnel device for mining and conveying. Background Art

[0002] The mining conveying funnel is a device for separating, screening and conveying ore. This funnel is usually composed of a funnel body, a conveyor belt, a motor and other parts. It can improve mining efficiency and ensure the quality and quantity of the ore. During the mining process, the mining funnel can temporarily keep most of the ore in the mine room. Workers stand on the ore pile to work. Through the funnel, the ore can be effectively guided to the designated location for subsequent processing and treatment;

[0003] When the ore is conveyed through the hopper, screening equipment is also used to screen out larger sized ores to prevent the hopper from being blocked. For example, the Chinese utility model patent disclosed by publication number: CN214086774U: Ore screening and feeding device, the application includes a feeding bin and a quantitative feeder arranged below the discharge port of the feeding bin, the feeding port of the feeding bin is provided with a grate, including a vibrating screen, the vibrating screen is obliquely arranged above the feeding port of the feeding bin, the bottom of the screen surface of the vibrating screen is provided with a guide plate inclined toward the feeding port of the feeding bin, the bottom of the feeding bin is located above the discharge port and is also provided with a shock absorbing mechanism, that is, the The application designs an inclined vibrating screen to screen out large ore stones, and the screened large ore stones are directly discharged from the discharge port. Although the application can screen the ore through the inclined guide plate, the size of the feed port at the top of the overall funnel is small, which limits the screening process. As a result, during the ore screening process, some ores that meet the size will also be discharged, so that the screened ore needs to be screened twice, which reduces the ore transportation efficiency and adds additional screening processes, increasing production costs. In addition, after the ore is screened and falls into the lower hopper, a large amount of spillover dust will be generated, causing pollution to the surrounding environment. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-Figure 7As shown, a plurality of upper dust suction ports 11 are provided on the inner side of the first dust suction channel 8 located above the first dividing plate 9, and a plurality of first lower dust suction ports 10 are provided on the inner side of the first dividing plate 9 located below the first dust suction channel 8. A fixed pipe 12 is fixedly installed at the middle position on the rear side of the upper blocking hopper 5, and the rear side of the fixed pipe 12 is connected to the input end of the external dust removal equipment through a pipeline. With the arrangement of the first dust suction channel 8 and the first dividing plate 9, and through the first lower dust suction ports 10 and the upper dust suction ports 11 arranged in a staggered manner at high and low, the dust generated during feeding in the hopper 1 can be sucked away. At the same time, the arrangement of the double-layer channel in the first dust suction channel 8 is conducive to lifting the first lower dust suction port 12 away from the fixed pipe 12. The dust suction capacity of the dust suction port 10 is improved. Two limit blocks 16 are fixedly installed on the outer side of the transmission shaft 7. Second shaft seats 13 are fixedly installed on both sides of the upper blocking hopper 5. A pad 14 is fixedly installed on the bottom of the upper blocking hopper 5. A third shaft seat 15 is fixedly connected between the upper blocking hopper 5 and the pad 14 located in front of the second shaft seat 13. The bottom of the third shaft seat 15 is rotatably connected to the corresponding support 4. An oil cylinder 27 is rotatably connected between the second shaft seat 13 and the corresponding first shaft seat 3. The two third shaft seats 15 are rotatably installed on the corresponding supports 4, so that the upper blocking hopper 5 is placed on the top of the hopper 1, so as to cooperate with the first shaft seat 3 to realize the removal of large pieces of mineral materials connected to the intercepting grille 25.

[0029] like Figure 4 , Figure 6-Figure 8 As shown, a plurality of second lower dust suction ports 19 are provided on the inner side of the second dust suction channel 26 located below the second dividing plate 18, a lower extension plate 20 is fixedly installed at the bottom of the baffle plate 28, a plurality of sliding openings 21 are provided in the lower extension plate 20, and a displacement plate 22 is movably connected to the bottom of the lower extension plate 20, and two fixing seats 17 are fixedly installed on the front side of the baffle plate 28, and the two fixing seats 17 are respectively inserted and installed on the corresponding limit blocks 16, and the rear side of the displacement plate 22 has a convex structure, and a plurality of plug plates 23 are fixedly installed on the top of the displacement plate 22, and the plug plates 23 are inserted and installed in the corresponding sliding openings 21, and a limiting rod 24 is fixedly connected between the plurality of plug plates 23 located at the front side of the baffle plate 28, and the displacement plate 22 is movably installed on one side of the baffle plate 28 through the plug plate 23 and the limiting rod 24, so that the transmission shaft 7 can drive the baffle plate 28 to rotate and open and close, and the displacement plate 22 can adaptively rise and fall without affecting the normal opening and closing of the baffle plate 28.

[0030] It should be noted that the utility model is a hopper device for mining transportation. Before use, the fixed pipe 12 can be connected to the input end of the external dust collector through a hose, and then the ore can be transported to the hopper 1. Before the ore falls into the hopper 1, it will be screened by the interception grid 25 in the upper baffle hopper 5, so that large pieces of ore or mineral soil blocks that do not meet the size requirements are intercepted, and the ore is directly intercepted and temporarily stored by the interception grid 25, while the large pieces of mineral soil blocks will be smashed by the ore or mineral soil blocks transported subsequently, so that some of the intercepted large pieces of mineral soil blocks are broken and enter the hopper 1. At this time, the adsorption force of the external dust collector is separated by the first partition plate 9 in the first dust suction channel 8, so that the dust generated when the hopper 1 is fed is sucked by the multiple first lower dust suction ports 10 and the upper dust suction ports 11 inside the first dust suction channel 8 and the multiple second lower dust suction ports 19 on one side of the baffle plate 28.

[0031] When it is necessary to remove the ore or ore blocks intercepted on the intercepting grid 25, the two cylinders 27 can be started during the feeding window period of the hopper 1, so that one end of the two cylinders 27 can cooperate with the two second shaft seats 13 to push the upper blocking hopper 5. As a result, the upper blocking hopper 5 rotates and tilts forward on the two supports 4 with the bottom of the two third shaft seats 15 as the axis. At this time, the two motors 6 are started synchronously, so that the two motors 6 synchronously drive the transmission shaft 7 to rotate, and the two limit blocks 16 on the outer side of the transmission shaft 7 synchronously drive the two fixed seats 17 on the front side of the baffle plate 28 to rotate, so that the fixed seat 17 drives the baffle plate 28 to rotate and open, and the bottom of the baffle plate 28 synchronously drives the displacement plate 22 to flip forward, so that the bottom of the displacement plate 22 is restricted by the pad 14 and moves upward, and the multiple plug plates 23 on the top of the displacement plate 22 move upward in the corresponding slide 21, thereby realizing The baffle plate 28 is flipped forward and opened, so that the ore on the intercepting grille 25 is discharged from the channel opened by the baffle plate 28 by its own gravity and the slope of the first dust suction channel 8. After the ore on the intercepting grille 25 is removed, the upper baffle hopper 5 can be reset with the help of two oil cylinders 27. At the same time, the two motors 6 drive the transmission shaft 7 to reset the baffle plate 28. When the baffle plate 28 drives the displacement plate 22 to move to the front side of the pad 14, since the displacement plate 22 needs to be tilted, the lowest end of the displacement plate 22 is lower than the height of the pad 14, so that the convex structure on the rear side of the displacement plate 22 is restricted by the front side of the pad 14 and is forced to move upward, so that the displacement plate 22 can follow the baffle plate 28 to flip back onto the pad 14, and cooperate with the baffle plate 28 to realize closing the through groove on the front side of the upper baffle hopper 5, and make the second dust suction channel 26 connected with the cavity of the first dust suction channel 8.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
