Abstract
Description
Technical Field
[0001] This utility model applies to the field of ore processing technology, and in particular relates to an ore crushing device for ironmaking. Background Technology
[0002] Currently, ore refers to a mineral aggregate from which useful components can be extracted or which has certain usable properties. In order to use the ore, it is often poured into a corresponding double-roll crusher, and the crushing process of the ore is achieved by the crushing rollers rotating in opposite directions inside the crusher.
[0003] However, in current methods of crushing ore using roller mills, the ore is often guided and conveyed into the mill via a feed frame. During this process, if the material is poured too quickly, it can easily accumulate excessively inside the mill, hindering thorough and rapid crushing. Furthermore, the pouring speed cannot be adjusted, significantly impacting the crushing quality and efficiency. Therefore, we propose an ore crushing device for ironmaking. Utility Model Content
[0004] The main objective of this invention is to provide an ore crushing device for iron smelting, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A crushing device for ironmaking ore includes a crushing box, with feed inlets on both sides of the top of the crushing box. Fixed plates are vertically fixedly installed on both ends of the top side of the crushing box, and the fixed plates are located on the side of the feed inlets. A guide plate is hinged to the top side of each fixed plate through a rotating shaft, and baffle plates are fixedly installed on both sides of the top of each guide plate.
[0007] Each of the fixed plates has a fixed frame fixedly installed horizontally on both outer ends. A transmission frame is fixedly installed between the sides of the two sets of fixed frames. A rotating screw is installed horizontally in the middle of the interior of each fixed frame via a bearing. A movable sleeve is movably sleeved on the outer surface of each rotating screw. A connecting block is fixedly installed on the top outer surface of each movable sleeve, and the connecting block is slidably installed inside the top of the fixed frame.
[0008] Each of the connecting blocks has a push rod hinged at an angle to its top surface via a pivot, and the top of the push rod is hinged to the bottom surface of the guide plate via the pivot.
[0009] By adopting the above technical solution, the horizontal movement force of the movable sleeve can be converted into a pushing force on the guide plate by the rotational transmission action of the rotating screw and the transmission conversion action of the push rod. While changing the inclination of the guide plate outside the feed inlet, the guiding and feeding speed of the guide plate is adjusted, so as to avoid the feeding speed of the ore material being too fast or too slow, which would affect the crushing quality and efficiency of the crusher box.
[0010] As an optional solution to the technical solution of this application, each of the transmission frames has a rotating rod rotatably mounted on both sides through bearings, and the side of the rotating rod is fixedly connected to the top of the side of the rotating screw. A transmission sprocket is fixedly sleeved on the middle surface of each of the rotating rods, and a transmission chain ring is meshed between the outer sides of the two sets of transmission sprockets. Both the transmission sprocket and the transmission chain ring are rotatably disposed inside the transmission frame.
[0011] By adopting the above technical solution, the rotating screws located on both sides of the bottom of the guide plate can rotate synchronously and in the same direction through the meshing transmission action of the transmission chain ring and the transmission sprocket.
[0012] As an optional solution to the technical solution of this application, each of the fixed frames has a limiting groove at the top center, and the connecting block is slidably inserted into the limiting groove.
[0013] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding sliding action of the connecting block through the limiting groove.
[0014] As an optional solution to the technical solution of this application, a servo motor is fixedly installed on the outer surface of each transmission frame, and the side of the servo motor transmission shaft is fixedly connected to the outer side of the rotating rod through a coupling.
[0015] By adopting the above technical solution, the power required for the rotation of the rotating rod is provided by the driving action of the servo motor.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The ore crushing device for ironmaking according to the technical solution of this application connects the two ends of the push rod to the bottom of the guide plate and the outside of the movable sleeve respectively through the rotating shaft. Under the rotational transmission action of the rotating screw on the movable sleeve, and the hinge of the guide plate and the fixed plate under the rotation action of the rotating shaft, the rotating screw drives the movable sleeve to move horizontally inside the fixed frame at the same time. Then, the push rod can convert the horizontal movement force of the movable sleeve into a pushing force on the guide plate. While changing the inclination of the guide plate outside the feed inlet, the guiding and feeding speed of the guide plate is adjusted to avoid the feeding speed of the ore being too fast or too slow, which would affect the crushing quality and efficiency of the crusher box.
[0018] By connecting the rotating rod and the rotating lead screw, and combining the meshing transmission action of the transmission sprocket and the transmission chain, the two sets of rotating lead screws can be driven synchronously and in the same direction by a servo motor in a single position. This ensures the rationality of the transmission of the push rods located on both sides of the bottom of the guide plate, while reducing the driving power source required for adjustment.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution: an ore crushing device for ironmaking, wherein a servo motor 33 is fixedly installed on the outer surface of each transmission frame 34, and the side of the transmission shaft of the servo motor 33 is fixedly connected to the outer side of the rotating rod 3 through a coupling.
[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each transmission frame 34 has a rotating rod 3 mounted on both sides inside via bearings, and the side of the rotating rod 3 is fixedly connected to the top of the side of the rotating screw 21. A transmission sprocket 31 is fixedly sleeved on the middle surface of each rotating rod 3. A transmission chain ring 32 is meshed between the outer sides of the two sets of transmission sprockets 31, and both the transmission sprocket 31 and the transmission chain ring 32 are rotatably disposed inside the transmission frame 34.
[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), the top of the crusher box 1 has a feed inlet 11 on both sides. The top side surfaces of the crusher box 1 are vertically fixed with a fixing plate 12, and the fixing plate 12 is located on the side of the feed inlet 11. The top side of each fixing plate 12 is hinged with a guide plate 13 through a rotating shaft. The top two sides of each guide plate 13 are fixed with a baffle plate 14.
[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each fixed plate 12 has a fixed frame 2 horizontally fixedly installed on both outer ends. A transmission frame 34 is fixedly installed between the sides of the two sets of fixed frames 2. A rotating screw 21 is horizontally rotatably installed in the middle of the interior of each fixed frame 2 through a bearing. A movable sleeve 22 is movably sleeved on the outer surface of each rotating screw 21. A connecting block 23 is fixedly installed on the top outer surface of each movable sleeve 22. The connecting block 23 is slidably installed inside the top of the fixed frame 2. A push rod 24 is inclinedly hinged to the top surface of each connecting block 23 through a rotating shaft. The top of the push rod 24 is hinged to the bottom surface of the guide plate 13 through a rotating shaft.
[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), each fixed frame 2 has a limiting groove 25 at the top center, and the connecting block 23 is slidably inserted into the limiting groove 25.
[0028] During operation, when ore needs to be crushed, depending on the size of the ore blocks, if the ore blocks are large, the external control switch is activated to turn on the servo motor 33, causing it to rotate. This rotates the rotating rod 3 and the transmission sprocket 31 fitted on its surface. Combined with the meshing transmission action of the transmission sprocket 31 and the transmission chain ring 32, this drives the rotating rod 3 and the rotating screw 21 located on both sides of the bottom of the guide plate 13 to rotate synchronously and in the same direction. Subsequently, the rotating screw 21 drives the movable sleeve 22 to rotate. 2. After moving horizontally within the fixed frame 2, the moving force of the movable sleeve 22 is converted into a pulling force on the guide plate 13 under the transmission conversion action of the push rod 24. This reduces the tilt angle between the guide plate 13 and the top of the guide plate 13, so that the ore material will not pass through the feed inlet 11 too quickly under its own gravity after accumulating on the surface of the guide plate 13. After the material moves into the crusher box 1 through the feed inlet 11, it is crushed by the crushing action of the crushing rollers rotating in opposite directions inside the crusher box 1.
